This  work  (Special  Bulletin  No.  2)  is  one  of  a  series  of  papers  intended  to  illustrate  the 
collections  belonging  to,  or  placed  in  charge  of,  the  Smithsonian  Institution,  and  deposited 
in  the  United  States  National  Museum. 

The  publications  of  the  National  Museum  consist  of  two  series — the  Bulletin  and  the 
Proceedings.  A  small  edition  of  each  paper  in  the  Proceedings  is  distributed  in  pamphlet 
form  to  specialists  in  advance  of  the  publication  of  the  bound  volume.  The  Bulletin  is 
issued  only  in  volumes.  Most  of  the  volumes  hitherto  published  have  been  octavos,  but  a 
quarto  form  has  been  adopted  for  works  of  the  size  and  character  of  the  present  Bulletin, 
this  being  No.  2  in  the  quarto  scries. 

The  Bulletin  of  the  United  States  National  Museum,  the  publication  of  which  was 
commenced  in  1875,  consists  of  elaborate  papers  based  upon  the  collections  of  the  Museum, 
reports  of  expeditions,  etc.  The  Proceedings  are  intended  to  facilitate  the -pi,ompt  publi- 
cation of  freshly  acquired  tacts  relating  to  biology,  anthropology,  and  geology,  descriptions 
of  restricted  groups  of  animals  and  plants,  discussions  of  particular  questions  relative  to 
the  synonymy  of  species,  and  the  diaries  of  minor  expeditions. 

Other  papers  of  more  general  popular  interest  are  printed  in  the  appendix  to  the 
annual  report. 

Papers  intended  for  publication  in  the  Proceedings  and  Bulletin  of  the  United  States 
National  Museum  are  referred  to  the  advisory  committee  on  publications,  composed  as 
follows:  Frederick  W.  True  (chairman),  R.  Edward'Earll  (editor),  James  E.Benedict,  Otis

OCEANIC    ICHTI I YOLOGY. 


INTRODUCTION. 


Orn  purpose  bus  been  to  present  in  Oceanic  Ichthyology  a  discussion  of  all  forms 

of  fisbes  found  in  the  seas  of  tbe  world, both  pelagic  species  and  those  occurring  at  deptbs 
greater  than  500  feet,  especial  prominence  being  given  to  those  species  which  arc  found  in 
tbe  Atlantic  Ocean,  most  of  which  we  have  bad  opportunity  to  study.  All  oceanic  fishes 
are  included,  partly  because  it  is  not  yet  possible  to  distinguish  strictly  between  the  two 
classes,  and  partly  because  the  pelagic  forms  have,  in  part  at  least,  been  mentioned  in  the 
discussions  by  all  previous  writers  on  "  deep-sea  fishes." 

By  Oceanic  fishes  we  mean  those  deep  sea  and  pelagic  species  which  dwell  in  the  open 
ocean  tar  from  the  shore,  either  at  the  surface,  at  the  bottom,  beyond  a  depth  of  500  feet,  or, 
if  such  fishes  there  be,  the  intermediate  zones. 

Oceanic  Ichthyology  is  that  branch  of  ichthyology  which  is  concerned  with  their  study. 

Deep-sea  fishes  are  those  which  are  found  at  a  depth  of  1,000  feet  or  more,  without 
reference  to  the  question  whether  or  not  they  also  occur  in  shallower  water.  The  limit  of 
500  feet  is  taken  for  convenience  in  the  study  of  the  origin  of  local  deep-sea  faunas.  The 
limit  of  100  fathoms  is  that  ordinarily  in  use.  Tbe  Eeports  of  the  Challenger  class  as 
'•deep-sea  deposits"  all  those  below  100  fathoms  depth.  Tbe  zone  between  the  litteral 
zone,  and  the  bathybial  zones,  500-1000  feet,  is  called  the  '•hcmibathybial  zone" 

rdagic  fishes  are  those  which  live  far  from  laud  and  at  a  distance  from  the  bottom, 
rarely  approaching  the  shore  except  when  driven  by  wind  or  current.  It  is  these  which 
are  most  closely  associated  with  the  "Plankton,"  and  were  included  in  it  before  the  mean- 
ing of  the  term,  as  proposed  by  Hensen,  was  limited  by  ILeckel.  Home  of  these,  which 
occur  at  considerable  depths,  we  call  "bathy pelagic." 

We  cannot  claim  that  in  the  present  memoir  we  have  brought  forward  any  conclusions 
which  are  new  to  science,  though  a  great  number  of  new  facts  are  recorded.  We  hope, 
however,  that  we  have  succeeded  in  the  attempt  to  bring  the  information  which  we  have 
ourselves  been  able  to  obtain  into  proper  relationship  with  the  mass  of  similar  knowledge 
already  recorded,  and  that  our  descriptions  are  so  accurate  and  full  that  the  deterioration 
or  loss  of  the  material  studied,  much  of  which  was  in  very  fragmentary  and  precarious  con- 
dition when  it  came  to  us,  may  not  be  entirely  disastrous.  We  have  tried  to  assemble  all 
existing  data  about  oceanic  fishes  and  to  arrange  them  in  such  a  manner  that  they  may  be 
serviceable  to  naturalists  in  other. fields  for  comparison  and  study,  as  well  as  to  ichthyolo- 
gists for  ready  reference,  when  at  a  distance  from  the  rather  extensive  group  of  books  which 
must  now  be  consulted  even  for  the  casual  identification  of  a  deep-sea  fish.  We  have  also 
endeavored  to  sum  up  the  conclusions  reached  by  previous  students  before  incorporating 
our  own  results  with  those  of  our  predecessors.* 

Note.— I  have  in  preparation  and  shall  booh  publish  an  extended  Btudyofthe  geographical  distribution 

of  deep-sea  and  pelagic  fishes,  and  of  the,  origin  of  the  several  bathybial  iisli  faunas.

IV  INTRODUCTION. 

When  this  volume  was  begun,  it  was  not  intended  to  include  so  large  a  field  within  its 
scope,  but  unexpected  delays  have  brought  us  to  a  time  when  there  is  an  entire  discontinu- 
ance of  deep-sea  work,  and  when  the  final  ichthyological  results  of  all  past  expeditions 
have  been  published. 

In  1885  Prof.  Collett,  of  the  University  of  Christiania,  published  a  volume  upon  the 
fishes  of  the  Norwegian  North  Sea  Expedition.  In  1887  Dr.  Gunther,  of  the  British  Museum, 
published  his  great  work  on  "  The  Deep-Sea  Fishes  of  the  Challenger  Expedition  ".  In  1888 
Dr.  Yaillant,  of  the  Museum  of  Natural  History  in  Paris, reported  upon  the  Deep-Sea  Fishes 
of  the  Travailleur  and  Talisman  Expedition,  and  in  the  same  year  Mr.  Alexander  Agassiz 
presented  his  admirable  "Contributions  to  American  Thalassography",  in  which,  for  the 
first  time,  were  presented  in  compact  form  the  results  of  the  ichthyological  work  of  the  Coast 
Survey  and  the  Fish  Commission. 

These  four  magnificent  works,  together  with  the  various  short  papers  since  published 
by  American  and  Scandinavian  naturalists  and  by  Mr.  S.  Alcock  upon  the  deep-sea  fishes  of 
India,  relate  to  a  group  of  animals  concerning  which,  until  recently,  naturalists  knew  almost 
nothing. 

The  study  of  oceanic  ichthyology  is  still  in  its  infancy  and  yet  many  very  remarkable 
results  have  been  obtained.  Although  not  more  than  600(f)  different  kinds  of  lishes  have 
been  obtained  from  the  depth  of  1,000  feet  and  more,  it  would  appear  that  a  very  good 
general  idea  of  the  character  of  the  fauna  has  already  been  acquired.  This  is  indicated 
by  the  fact  that  fishes  are  constantly  being  rediscovered  in  the  most  remote  localities.  A 
form  obtained  by  Lowe  in  Madeira  in  1870  was  rediscovered  by  us  off  the  New  England 
coasl  in  1881,  and  by  German  naturalists  in  the  Japanese  Sea  in  L879,  by  the  Blake  near 
Barbadoes  in  1880,  and  a  year  or  two  later  jff  the  coast  of  Soudan.  Several  previously 
known  only  from  New  Zealand  have  been  obtained  by  the  Fish  Commission  off  the  New 
England  coast,  and  some  of  our  own  genera  and  species  have  lately  been  discovered  in  tin- 
Bay  of  Bengal. 

Although  the  capture  of  certain  individual  forms  in  widely  remote  localities  in  the 
oceanic  abyss  might  l>e  interpreted  to  mean  that  the  field  has  been  somewhat  fully 
explored,  and  that  it  is  now  being  gone  over  a  second  or  third  time,  such  an  interpretation 
would  be  misleading.  Our  knowledge  of  abyssal  life  is  still  exceedingly  imperfect.  New 
species  and  genera  are  obtained  every  time  the  nets  are  lowered  to  the  bottom  in  an 
untried  spot.  Very  many  forms  have  been  taken  in  only  one  locality,  and  are  represented 
in  the  museums  by  unique  specimens,  so  that  the  ichthyologist  has  not  material  enough  to 
enable  him  to  study  the  structure  of  the  organisms  to  which  he  has  given  a  name.  Then, 
too,  the  appliances  for  the  capture  of  the  fishes  of  any  region,  especially  those  which  are 
believed  to  live  suspended  in  the  middle  strata  of  mid-ocean,  are  so  imperfect,  and  the  like- 
lihood is  great  that  there  are  many  forms  so  organized  that  they  can  not  well  be  taken 
by  small  slow-moving  nets,  that  naturalists  will  surely  fall  into  error  if  they  suppose 
themselves  in  possession  of  anything  like  an  adequate  equipment  for  a  final  study  of  the 
subject. 

It  seems  probable  that  there  are  many  inhabitants  of  the  depths  which  are  too  swift, 
too  wary  and  cunning,  or  too  large  thus  to  be  taken.  It  cannot  be  doubted,  for  example, 
that  somewhere  in  the  sea,  at  an  unknown  distance  below  the  surface,  there  are  living 
certain  fish-like  animals,  unknown  to  science  and  of  great  size,  which  come  occasionally  to 
the  surface  and  give  a  foundation  to  such  stories  as  those  of  the  sea  serpent. 

To  appreciate  the  meager  extent  of  our  knowledge  of  what  is  going  on  in  mid-ocean  it 
is  only  necessary  to  think  of  such  a  fish  as  Ghiasmodon  and  its  history.  Ghiasmodon  is 
one  of  those  grotesque  looking  pelagic  fishes  with  yawning,  flexible  jaws  and  a  vastly 
distensible  stomach,  which  is  able  to  engorge  other  fishes  equal,  or  more  than  equal,  in  size 
to  itself.  This  practice  is  naturally  attended  by  disaster,  and  the  Ghiasmodon,  in  the  event 
of  death,  is  brought  to  the  surface  by  the  expansion  of  the  gases  in  its  tissues.  Such 
accidents  evidently  happen  very  often.  The  chances  were  few.  nevertheless,  that  waifs  of 
this  kind  should  fall  into  the  hands  of  naturalists,  and  yet  within  forty  years  Ghiasmodon

has  occurred  five  times.    '  In  I  lie  other  hand,  Chiasmodon,  although  so  abundant,  lias  only 
once  been  taken  by  the  deep-sea  nets. 

Another  ocean  dweller  which  the  exploring  ships  have  not  yet  discovered  is 
Regalecus,  or  the  "Oar-fish,"  a  serpent  shaped,  rapidly  swimming  form,  usually  from  18 
to  24  feel  in  length,  which  occasionally  is  stranded  on  the  shore  in  the  storms  season. 
Within  the  pasi  one  hundred  and  fifty  years  individuals  have  visited  the  shores  of  Nor 
way,  Fininark,  the  Faroe  Islands,  Scotland.  Ireland,  England,  Mediterranean,  Prance, 
Bermuda,  the  Oapeof  Good  Hope,  Hindustan,  and  New  Zealand.  Gunther  gives  a  list 
of  44  seen  by  naturalists,  and  this  is  of  course  hut  an  insignificant  pari  of  those  which 
have  actually  been  stranded.  Its  world  wide  distribution  and  the  number  of  wait's  give 
evidence  that  it  is  abundant  in  mid-ocean, yet  the  exploring  ships  in  all  the  years  of  their 
combined  searchings  have  found  no  vestiges  of  it,  old  or  young. 

Many  similar  eases  might  be  cited,  but  our  object  is  simply  to  call  attention  to  the 
great  necessity  for  further  exploration  of  the  depths. 

The  distinctions  between  the  inhabitants  of  deep  water,  those  of  the  middle  depths, 
and  those  of  the  surface  strata  of  mid-ocean  are  not  yet  absolutely  tixed.  Such  are  the 
imperfections  in  the  methods  of  trawling  and  dredging  that  the  naturalist,  when  he  has 
sorted  out  the  fishes  from  his  nets  after  a  haul  in  mid  ocean,  is  often  in  doubt  as  to  where 
his  captures  have  been  made.  If  he  has  taken  a  flounder  from  a  haul  of  800  fathoms,  or 
finds  a  macrurid,  a  brotulid,  a  stomiatid,  a  synodontid,  or  a  neinichthyid  in  a  net  which 
has  been  below  the  2,000-fathom  line,  he  feels  reasonably  sure  that  he  has  brought  it  up 
from  the  bottom.  But  who  shall  say  where  Argyropeleeus,  Stemoptyx,  Myctopkum,  having 
allies  among  the  pelagic  fishes  in  the  same  net,  have  come  from?  It  may  be  from  the 
bottom,  or  they  may  have  become  entangled  in  the  meshes  of  the  trawl  when  but  a  few 
fathoms  from  the  surface,  coming  up  or  going  down. 

The  recent  investigations  of  Mr.  Agassiz  in  the  Pacific,  with  the  Tanner  net,  seem  to 
show  pretty  conclusively  that  there  are  but  few  living  forms  belowT  a  depth  of  1,80b  or  2,000 
feet  and  that  the  Myctophidce  stay  for  the  most  part,  if  not  entirely,  between  that  depth  and 
the  surface.  It  is  possible  to  draw  inferences  from  the  experiments  in  regard  to  many  forms 
which,  like  the  Myctophidce,  are  known  frequently  to  occur  swimming  at  the  surface  at 
night,  but  there  are  also  doubtful  cases,  like  Bathyophis,  Bhodichthys,  Microstoma,  and  many 
others,  which  need  further  consideration. 

Another  greatneed  is  for  more,  and  more  perfect,  material.     Fully  one-half  of  the  deep 
sea  forms  are  now  represented  only  by  single  specimens,  and   many  important  anatomical 
questions  can  not  be  solved,  because  these  uniques  may  not  be  sacrificed  to  dissection.     Half 
of  the  families  of  Malacopterygians  mentioned  in  this  report  can  not  be  assigned  to  their 
proper  places,  because  their  skeletons  have  not  been  fully  examined. 

Besides  this,  the  imperfection  of  the  existing  specimens  is  a  great  drawback.  The 
material  is  of  a  kind  which  it  is  peculiarly  difficult  to  study.  Not  only  are  the  forms 
strange  and  difficult  to  assign  to  their  proper  taxonomic  relationships,  but,  owing  to  the 
soft,  cavernous  skeletons,  and  the  flabby  muscles,  tender  skins,  deciduous  scales,  and  fragile 
appendages  which  are  characteristic  of  many  of  them,  they  are  very  liable  to  injury.  After 
these  delicate  animals  have  been  drawn  up  from  a  depth  of  2  or  3  miles  in  rough  nets,  they 
are,  as  might  be  expected,  in  a  very  dilapidated  condition.  It  has  often  been  found  neces- 
sary to  examine  a  score  of  more  of  individuals,  in  order  to  be  able  to  appreciate  characters 
which  could  commonly  be  made  out  from  a  single  specimen. 

The  Studies  which  have  led  to  the  writing  of  this  book  were  begun  in  the  summer  of 
1 s T 7 .  when  the  first  deep-sea  fishes  \w\i-  caught  by  American  nets  on  the  coast  of  North 
America.  This  took  place  in  the  Gulf  of  Maine,  4  1  miles  cist  of  <  Sape  Ann,  on  the  L9th  of 
August,  when  from  the  side  of  the  I".  S.  Pish  Commission  steamer  Speedwell  the  trawl  net 
was  cast  in  L60  fathoms  of  water.  The  writers  were  both  standing  by  the  mouth  of  the  net 
when,  as  the  seaman  lifted  the  end  of  the  bag,  two  strange  forms  fell  out  on  the  deck.  A 
single  glance  was  enough  to  tell  us  that  they  were  new  to  our  fauna,  and  probably  unkuow  n 
to  science.    They  seemed  like  visitors  from  another  world,  and  none  of  the  strange  forms 


VI  INTRODUCTION. 

which  have  since  passed  through  our  laboratory  have  brought  half  as  much  interest  and 
enthusiasm.  Macrurus  Bairdii  and  Lycodes  Verrillii  were  simply  new  species  of  well- 
known  deep-dwelling  genera,  and  have  since  been  found  to  be  very  abundant  on  the  con- 
tinental slope,  but  they  were  among  the  tirst  fruits  of  that  great  harvest  in  the  field  of 
oceanic  ichthyology  which  we  have  had  the  pleasure  of  helping  to  garner  in  the  fifteen 
years  which  have  passed  since  that  happy  and  eventful  morning.  It  seems  incredible  that 
American  naturalists  should  not  then  have  known  that  a  few  miles  away  there  was  a  fauna 
as  unlike  that  of  our  coast  as  could  be  found  in  the  Indian  Ocean  or  the  seas  of  China. 

It  should  be  remembered  that  although  the  Challenger  has  been  back  more  than  a  year 
from  her  long  cruise,  her  treasures  were  as  yet  undescribed,  and  that  no  one  knew  what  a 
marvelous  wealth  of  material  she  had  gathered  except  the  naturalists  on  board.  Even 
they  can  scarcely  have  expected  that  year  after  year  the  great  quarto  volumes  of  these  final 
reports  would  continue  to  be  printed,  until  to-day  there  are  forty  of  them — the  magnificent 
outcome  of  the  most  liberally  equipped  exploring  expedition  ever  sent  out  by  any  nation. 
Oceanic  ichthyology  was  as  yet  unborn. 

A  year  later  Dr.  (liinther  began  to  publish  the  preliminary  descriptions  of  the  Chal- 
lenger fishes  in  the  London  Annals  and  Magazine  of  Natural  History,  and  a  new  interest  was 
added  to  the  study  of  ichthyology.  From  that  time  until  now  we  have  never  been  without 
a  wealth  of  attractive  oceanic  material  for  study,  and  the  genera  and  species  announced 
by  us  from  the  western  Atlantic  have  been  more  in  number  than  those  brought  back  by  the 
Challenger,  yet  the  discoveries  made  in  those  earliest  years  have  always  seemed  the  most 
interesting. 

It  may  be  asked  how  it  happened  that  no  deep-sea  fishes  had  been  taken  by  the  Coast 
Survey  vessels  which  began  dredging  in  1867,  or  by  those  of  the  Fish  Commission  which 
began  in  1871.  The  answer  is  a  simple  one.  The  Fish  Commission  vessels  were  small, 
and  did  not  venture  outside  of  the  hundred  fathom  line  until  1877,  and  the  Coast  Survey 
in  those  days  collected  with  the  dredge  only.  When  Mr.  Agassi/,  took  charge  of  the  bio- 
logical work  of  the  Coast  Survey,  in  1877,  he  introduced  the  trawl  net,  and  began  to  collect 
fishes,  but  these  did  not  come  into  our  hands  uutil  1883.  The  nets  were  not  really  per- 
fected until  1883,  when  the  Albatross  and  the  Travailleur  began  their  cruises. 

In  1878  the  headquarters  of  the  Fish  Commission  was  at  Gloucester,  and  we  began  to 
receive  from  the  Cape  Ann  fishermen  deep-sea  forms  taken  by  them  on  the  off-shore  banks. 
In  this  way  came  our  Haloporphyrus  viola  and  Lycodes  paxillus,  brought  by  Capt.  J.  W. 
Collins,  then  of  the  halibut  schooner  Marion  and  since  well-known  by  his  writings  upon 
the  fisheries;  our  Argentina  syrlensium,  G.  &  B.  (since  identified  with  A.  situs  of  Europe); 
Lycodes  Vahlii,  a  Greenland  form,  brought  by  Capt.  Hawkins,  of  the  schooner  Gwendolen  : 
Anarrhiehas  lati/rons,  Alepidosaurus  ferox,  Alepocephalus  Bairdii,  G.  &  B.;  Synaphobranchus 
pinnatus,  Simenchelys parasiticus,  Gill;  Chinuvra plumbea,  Gill  (=ajfinis,  Boc.  &Cap.);  Cen- 
troscyllium  Fdbrieii  and  Gentroscymnus  aelolepis,  Echiostoma  barbatum,  Ghauliodus  Sloanei, 
Reinhardtius  Mppoglossoides,  Macrurus  rupestris,  Lopholatilus  chamceleonticeps,  G-.  &  B. — all 
received  in  time  to  be  catalogued  in  our  Fishes  of  Essex  County,  Massachusetts,  published 
in  1879,  together  with  Phycis  Chesteri,  G,  &  B.,  and  Eumicrotremus  spinosus,  obtained  in  the 
same  year  by  the  Fish  Commission  vessels. 

In  1880  the  Fish  Commission  began  its  explorations  of  the  Gulf  Stream  off  the  south 
coast  of  New  England.  Dr.  Bean  was  on  the  Pacific  coast  and  the  following  were  described 
by  Dr.  Goode:  Monolene  sessilicauda,  Citharichthys  arctifrons,  C.  unicornis,  Thyris  pellucidus, 
Hypsicometes  gobioides,  Peristedium  miniatum,  Macrurus  carminatus,  Halieutaea  senticosa, 
Limanda  Beanii,  Amitra  liparina,  Cottunculus  forms,  Setarches parmatus,  Chlorophtlialmus 
chalybeius,  Wotacanthusphasganorus,  Monolene,  Hypsicometes,  and  Amitra  being  new  genera, 
and  Mancalias  uranoscopus,  Ghaunax  pictus,  and  Cottunculus  Thomsoni  were  added  to  the 
fauna. 

Apogon  pandionis  and  Benthodesmus  elongatus  were  found  in  the  same  year. 

In  1881  we  undertook,  at  the  request  of  Prof.  Baird  and  Mr.  Agassiz,  to  produce  a 
work  upon  the  fishes  of  the  Coast  Survey  and  the  Fish  Commission  together,  ami  discon-

upon  them  without  much  delay.     It  was  not   until   1891,  however,  that  we  were  able  to 

complete  our  studies,  the  illness  and  death  of  Prof.  Baird  having  interrupted  the  work 
and   thrown   upon  each  of  us  new  responsibilities  w  hich  left  little  time  at  our  command. 

We  had.  however,  prepared  for  Mr.  Agassiz  preliminary  reports  u] the  deep  sea  fishes 

of  the  Blake,  taken  in  1880  (published  in  L883),  and  upon  those  taken  in  1878 and  l.sT'.i  (pub- 
lished in  issili,  and  had  also  furnished  the  notes  upon  the  fishes  for  his  general  work.  Three 
<  'raises  of  the  Blake.  Besides  the  Blake  fishes  of  1878-'79-'80,  we  eon  tinned  to  receive  those 
from  the  Albatross  until  that  vessel  passed  into  the  Pacific  in  1888.  Her  more  recent  collec- 
tions are  being  worked  up  by  Prof.  C.  11.  Gilbert  and  by  Dr.  Bean,  who  is  studying  those 
of  the  Alaskan  seas,  and  by  Mr.  <  larman,  who  is  reporting  upon  thoseobtained  off  the  west 
coast  of  Central  America,  partly  made  under  the  direction  of  Mr.  Agassiz  in  1891. 

The  \\  ork,  as  it  now  appears,  is  in  many  respects  very  unsatisfactory  to  its  authors.  It 
has  been  written  at  odd  hours  snatched  from  administrative  duties,  too  often  in  the  very 
midst  of  them — always  under  the  pressure  of  haste,  and  always  with  the  feeling  of  impa- 
tience that  more  exhaustive  studies  could  not  be  made.  Later,  serious  illness  delayed  its 
printing. 

As  first  planned  it  was  to  include  only  the  oceanic  fishes  of  the  east  coast  of  North 
America,  but  it,  gradually  expanded  to  embrace  all  those  species  of  the  Atlantic  Basin  and 
all  the  oceanic  genera  of  the  world. 

It  was  first  ready  for  the  press  in  1885,  then  revised  and  rewritten  in  1888,  then  again 
in  1891,  and  again  in  18'J1  as  it  was  going  through  the  press. 

The  appearance  of  Giinther's  final  reports  upon  the  Challenger  fishes,  1SS7.  of  Yaillant's 
upon  those  of  the  Travailleur  in  1888,  of  Alcoek's  Investigator  papers  in  1889-1892,  of  Col- 
lett's  Hirondelle  notes  in  1889,  have  each,  in  their  turn,  caused  much  revision  and  rewrit- 
ing, and  the  appearance  of  Liitken's  Spolia  Atlantiea,  Part  II,  printed  in  1892,  has  made  it 
necessary  to  reset  a  number  of  pages. 

In  its  present  form  it  stands  as  a  compendium  and  summary  of  existing  knowledge  in 
regard  to  Oceanic  Ichthyology.  No  one  knows  when  there  will  be  opportunity  for  its 
further  study.  There  are  no  expeditions  and  there  seems  to  be  no  prospect  for  new  ones. 
Even  the  A Ibatross,  built  by  the  United  States  expressly  for  this  servicers  diverted  to 
police  duty  about  the  Seal  Islands. 

Public  interest  is  sated  by  the  crude  preliminary  results  already  obtained.  The  scien- 
tific world  knows  that  the  knowledge  of  to-day,  in  all  branches  of  thalassographic  work,  is 
incomplete  and  rudimentary  in  the  extreme,  and  that,  with  the  experience  now  acquired, 
the  results  of  future  exploration  will  be  immensely  greater.  We  can  only  hope  for  a 
renaissance  in  this  field. 

In  making  acknowledgments  to  those  who  have  aided  in  this  work,  we  think  first  of 
our  dear  friend,  the  late  Prof.  Baird,  of  the  pains  with  which  he  provided  every  facility, 
and  of  the  interest  with  which,  twice  a  day,  when  studies  were  in  progress,  he  came  to  the 
laboratory  to  talk  over  the  discoveries  and  discuss  them.  To  his  successor  as  Commissioner 
of  Fisheries,  Col.  McDonald,  we  owe  the  granting  of  every  request  we  have  made,  and  our 
requests  have  been  many.  To  Mr.  Alexander  Agassiz  we  are  likewise  indebted  for  coin 
tesies  many  and  great,  not  the  least  of  which  is  the  patience  with  which  lie  has  waited 
ten  years  for  a  report  which  was  promised  in  three.  To  Prof.  Theodore  Gill  we  offer  our 
thanks  for  counsel  and  information,  lavishly  and  ungrudgingly  bestowed,  out  of  the  fullness 
of  his  ichthyological  wisdom.  To  Commander  Z.  L.  Tanner,  U.  S.  N.,  in  command  of  the 
Albatross,  and  Mr.  J.  E.  Benedict,  naturalist  of  the  ship,  much  is  due  for  the  manner  in 
which  the  collections  were  gathered  and  preserved.  To  Dr.  Giinther  we  owe  inspiration 
and  kindly  advice;  to  Dr.  Sauvage,  of  the  Museum  of  Natural  History  in  Paris,  to  Dr. 
Liitken,  to  Prof.  Collett  and  to  Dr.  Alcock,  to  Dr.  Bilgendorf,  President  Jordan,  and 
Mr.  Carman,  frequent  letters  and  the  use  of  specimens;  to  Prof.  Giglioli,  the  use  of  his 
matchless  collection  of  Italian  vertebrates,  among  which  were  the  fishes  collected  by 
the  steamer   Washington  in  the  Mediterranean.     Capt.  H.  T.   Brian,  of  the  Government 


VIII  INTRODUCTION. 

Printing  Office,  has  also  aided  materially  in  the  work  by  his  advice.  Mr.  Barton  A.  Bean 
has  aided  in  the  handling  of  the  collections  and  illustrations  and  measurement  of  speci- 
mens, and  Mr.  J.  L.  Willige  has  rendered  useful  service  in  the  preparation  of  the  tables  of 
locality  and  distribution  and  in  proof  reading. 

Only  twenty  years  ago  the  fish  fauna  of  the  deep  sea  was  represented  in  collections  by 
forty  or  fifty  specimens,  representing  not  more  than  twenty  species  at  the  most — acci- 
dental waifs  picked  up  at  the  surface  or  cast  ashore  by  the  waves — "like  the  few  stray 
bodies  of  strange  red  men  which  tradition  reports  to  have  been  washed  on  the  shores  of 
the  Old  World  before  the  discovery  of  the  New,  and  which  served  to  indicate  the  existence 
of  unexplored  realms  inhabited  by  unknown  races,  but  not  to  supply  information  about  their 
character,  habits,  and  history."  ' 

If  the  coming  twenty  years  shall  produce  one-tenth  so  much  in  the  way  of  discovery  in 

the  life  of  the  deep  seas,  it  will  be  more  than  it  now  seems  reasonable  to  expect.

A  DISCUSSION  OF  THE  SPECIES  AND  THEIR  DISTRIBUTION. 


Class  MARSIPOBRANCHII. 

Startipobranchii,  Bonaparte,  Trans.  I. inn.  Soc.  London,  v.  is,  pp.  289,  304,  1841. 
Marsipobranchia,  Gill,  Johnson's  Cyclopaedia,  m,  310. 
Dermopteri  (part),  Owex,  Anatomy  of  Vertebrates,  i,  7. 

Skeleton  of  a  very  inferior  type,  the  notochord  or  embryonal  vertebral  column  being 
persistent.  Skull  rudimentary  and  represented  by  a  small  brain  case  and  capsules  for 
the  organs  of  sense  (auditory  and  olfactory),  as  well  as  by  an  ethmovonierine  plate:  the 
inferior  appendages  developed  as  elements  designated  as  the  "subocular  arch."  with  a 
metapterygoid  or  "superior  quadrate"  and  an  "inferior  quadrate"  portion,  the  "palato 
pterygoid"  element,  and  the  "stylohyal  process;"  labial  cartilages  form  also  a  prominent 
feature  of  the  skull;  bones  or  cartilages,  representing  the  upper  as  well  as  the  lower  jaws. 
entirely  wanting;  the  branchial  apparatus  sustained  by  a  basket  like  skeleton;  no  limbs 
developed,  and  no  scapular  arch  or  pelvic  girdle.  Brain  small  hut  distinctly  developed, 
differentiated  into  the  brain  proper  and  medulla  oblongata;  the  former  composed,  as  in  the 
higher  forms,  of  the  "mesencephalon,"  "thalamencephalon,"  "prosencephalon,"  and  "rhinen- 
cephalon;"  the  latter  small,  with  a  fourth  ventricle  conspicuous  from  above,  and  the  "cere- 
bellum" very  rudimentary.  Auditory  apparatus  quite  simple,  represented  by  a  single  mem 
branous  tube  without  any  differentiation  into  canals  and  vestibules,  as  in  the  Hyperotreta, 
or,  at  most,  as  in  the  Hyperoartia,  with  two  semicular  canals  and  a  sacculated  vestibule. 
Olfactory  apparatus  consists  of  a  median  sac:  is  provided  with  but  a  single  external  aper- 
ture. Heart  distinctly  developed  and  divided  into  an  auricle  and  ventricle,  the  former  hav- 
ing in  front  a  venous  sinus,  ami  the  whole  inclosed  in  a  "  pericardium,"  which  connects  with 
the  peritoneal  cavity.  Intestinal  canal  simple;  liver  specialized  as  such,  and  kidneys  well 
developed,  with  ureters  opening  behind  into  the  rectum.  Organs  of  generation  without 
ducts,  discharging  into  the  abdomen,  from  which  the  products  depart  by  an  abdominal  pore. 

The  species  of  the  class  are  found  in  both  fresh  and  salt  waters,  the  Petromyzontids 
having  members  in  the  fresh  and  salt  waters  of  all  temperate  and  subtemperate  countries: 
while  the  Myxinoids  are  represented  in  the  cold  waters  of  tin;  northern  hemisphere  by 
Mi/. rinc,  as  well  as  along  the  shores  of  a  considerable  portion  of  the  Pacific — in  the 
Japanese  and  Chinese  seas,  California,  Chile,  and  Australia.

2  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

Although  no  representatives  of  the  class  have  been  found  in  a  fossil  condition,  their 
absence  in  the  older  strata  is  undoubtedly  due  rather  to  the  difficulty  connected  with  the 
preservation  of  the  readily  destructible  cartilaginous  skeleton  than  to  their  actual  absence. 
It  is  indeed  probable  that  the  order  was  extensively  represented  in  past  times  and  that  it 
was  more  abundautly  developed  than  any  other  type.     (Gill.) 


Order  HYPEROTRETA. 

Cyelostomata  hyperotreta,  Mcller,  Abhandl.  Akad.  Wiss. 
Hyperotreta.  Gill,  .lohnson's  Cyclopaedia,  n,  1079. 

An  order  of  marsipobranchiates  characterized  by  the  construction  of  the  cranial  carti- 
lages and  the  complete  tabulation  of  the  median  nasal  aperture,  and  its  perforation  of  the 
palate  (hence  the  name).  The  branchial  apertures  are  developed  on  each  side  far  behind 
the  head,  and  arc  variable  in  number:  the  inner  branchial  ducts  communicate  directly 
with  the  esophagus;  the  ova  arc  large  and  each  is  provided  with  an  oval  horny  case  con- 
stricted at  both  ends,  and  with  numerous  filaments  thereto.  The  embryology  is  still  unknown. 
In  the  adult  condition  the  mouth  has  no  lips  and  no  plates  on  the  disk,  but  a  median  tooth 
is  above  the  entrance  of  the  esophagus,  and  two  pectinifonn  rows  of  teeth  on  the  tongue. 

The  order  is  composed  of  two  families:  (1)  Myxinidce,  with  one  geuus,  Myxine,  repre- 
sented by  species  in  the  northern  and  southern  hemispheres;  and  (2)  Bdellostomidce,  whose 
species  are  confined  to  the  Pacific  Ocean,  one  of  them  ascending  as  far  northward  as  Cali- 
fornia.   (Gill.) 

Family  MYXINIDCE. 

Afyxinidce,  GCxther,  Cat.  Fish.  Brit.  Mus.,  vm,  1870,  510. 

MYXINE,  Linnseus. 

Myxine,  I. inn  i:cs,  System:!  Naturae,  ed.  x,  1.  1758,  650  I  type,  Myxine  glutinosa,  L.). 

Body  eel  shaped,  covered  by  a  thin  loose  skin  ;  two  rows  of  mucous  glands  along  the 
lower  side.  Eyes  absent.  Skull  little  developed,  cartilaginous.  Mouth  lipless,  suctorial, 
with  barbels  on  each  side.  Nostril  single,  median,  at  front  of  head,  with  two  pairs  of 
barbels.  Teeth  strong,  a  single  one  on  the  roof  of  the  mouth,  and  two  rows  on  each  side 
uf  the  tongue.  < 4 ill  sacs  at  the  sides  of  esophagus  near  the  left  branchial  opening;  a  third 
opening  to  esophagus  and  the  branchial  sacs.    Ovary  single,  on  right  side.    No  oviducts. 

MYXINE   GLCTINoSA,  Lixx.s:is.     (Figure  1.) 
Myxine  glutinosa,   Linn.,  Syst.  Nat.,  ed.  x.  i.  65  i;  ed.  xn,  1080. — Gunther,  Cat.  Fish.  Brit.  Mus.,  vm.  510. 

A  Myxine  with  8-11  rather  slender  lingual  teeth  in  each  row,  the  two  foremost  strongest 
and  more  confluent  at  the  base  thau  the  others.  Length  of  head  contained  3i  to  4  times  in 
total  length ;  tail  6  J  to  10  times.     Color  grayish  brown  to  bluish  brown  above,  whitish  below. 

Linmvus  included  Myxine  among  his  '•  Vermes  Intestinal  placing  it  between  the  leeches 
and  the  shipworms,  and  described  its  habits  briefly  as  follows:  "IntreU  etdevorat  pisces; 
aquam  in  gluten  mutat,"  and  this  sentence  expresses  nearly  all  that  is  known  about  the 
habits  of  the  animal  at  the  present  time.  It  may  be  said,  however,  that  it  is  found  only  in 
waters  of  low  temperature,  probably  always  below  50°,  and  that  on  account  of  its  parasitic 
habits  its  capture  is  not  likely  to  be  effected  except  in  connection  with  some  larger  fish  on 
which  it  is  preying.  Its  presence,  therefore,  is  not  certain  to  be  detected  by  the  trawl  and 
dredge.  The  "slime-eel,"  as  it  is  called,  frequently  penetrates  into  the  abdominal  cavity  of 
other  fishes  to  feed  upon  their  flesh.    It  secretes  thick,  glutinous  slime,  in  enormous  quan-

tities  and  with  wonderful  rapidity.  A  single  hag  will  till  a  two-gallon  bucket  with  slime 
mingled  with  water  in  a  few  .seconds,  and  after  a  slight  interval  can  repeat  the  operation 
with  ease.  The  ei:u's  are  elliptical  in  shape,  and  are  supplied  at  each  end  with  numerous 
short  threads  for  adhesion.  Nansen  has  made  an  exceedingly  interesting  investigation  into 
the  hermaphroditism  of  this  form. 

Myxine  occurs  only  in  the  North  Atlantic.  On  the  coasts  of  Europe  it  is  found  in  the  Nor- 
wegian Fiords  as  deep  as  70  fathoms,  and  it  ranges  as  far  south  as  Newcastle  and  the  Firth 
of  Forth.  In  the  western  Atlantic  it  is  known  to  occur  on  the  offshore  banks  as  far  north 
as  the  Grand  Bank  of  Newfoundland,  and  probably  still  farther  north  through  the  Arctic 
Sea;  and  it  also  occurs  on  the  shoals  in  the  Hay  of  Fundy,  one  of  the  best  known  colonies 
being  on  the  cod  bank  to  the  eastward  of  the  north  end  of  the  island  of  Grand  Man  an. 
The  fishermen  of  the  offshore  banks  frequently  pull  them  to  the  surface  clinging  to  the  fish 
taken  on  their  hooks.  In  the  deeper  waters  of  the  western  Atlantic  they  have  been  found 
as  far  south  as  lat.  38°  31',  Ion.  73°  25',  off  the  capes  of  Delaware  by  the  Fish  Commis- 
sion at  a  depth  of  126  fathoms,  and  off  Cape  Fear,  North  Carolina,  lat.  34°,  Ion.  76°  10', 
at  a  depth  of  178  fathoms.  Off  Marthas  Vineyard  they  have  been  found  by  the  Fish  Com- 
mission at  a  depth  of  264  fathoms,  with  a  temperature  of  47°,  and  farther  out  at  sea  in  the 
same  region  by  the  Blake  at  304  fathoms  (lat.  40°  11'  40",  Ion.  68°  22'),  and  524  fathoms 
(lat.  41°  32',  Ion.  65°  55'). 

The  form  is  so  abundant  off  the  New  England  coast  in  depths  of  100  to  250  fathoms  that  a 
record  of  all  the  localities  of  its  occurrence  has  not  been  kept.  It  is  known,  however,  that 
specimens  were  obtained  from  the  following  stations  of  the  Blake:  309,  306,  and  327;  and 
also  from  the  following  stations  of  the  Fish  Commission  steamers:  8G9,  870,  871,  878,  939, 
951,  1038,  1047,  1154,  2080,  20SX,  2089,  2092. 

MYXINE  AUSTRALIS,  Jenyns.     (Figure  2.) 

Myxine  australis,  Jenyns,  Voyage  of  H.  M.  S.  Beagle,  Zoology  (edited  by  Charles  Darwin),  1839-'43;  Fishes; 
•     159;  Gcnther,  Cat.  Fish.  Brit.  Mas.,  vm,  1870,  511;  Challenger  Report,  xxn,  1887,  2157. 
ffeptatrema  oirrhatum,  Schlegel,  Fauna  Japonlca,  Poissons,  310,  pi.  143  (fide  Giinther). 

A  Myxine  with  ten  or  eleven  slender  teeth  in  each  of  the  two  series;  the  three  foremost 
strongest  and  confluent  at  the  base,  the  other  teeth  remaining  separate;  in  the  second 
series  the  two  innermost  teeth  are  confluent  at  the  base. 

,1/.  australis  was  first  described  from  Sandy  Point  and  the  Tyssen  Island,  at  the  south- 
ern extremity  of  .South  America.  It.  was  found  by  the  Challenger  in  the  Japanese  Sea, 
where  six  specimens  from  9  to  20  inches  in  length  were  taken  on  the  Hyalonema  ground  at 
a  depth  of  345  fathoms  (Station  232).  Dr.  Giinther  isof  the  opinion  that  Heptatrema  oirrha- 
tum Schlegel,  from  Japan,  should  be  referred  to  the  same  species.  The  Challenger  obtained 
specimens  of  M.  australis  from  the  Straits  of  Magellan,  and  the  species  is  most  probably  an 
inhabitant  of  the  deeper  waters  to  the  east  of  Patagonia,  and  entitled  to  a  place  in  the 
fauna  of  the  Atlantic  basin. 

Order  HYPEROARTIA. 

Cyclostomata  hyperoartia,  Miller,  Abhandl.  Akad.  Wiss.,  Berlin,  1834,  77. 
Ryperoartia,  Gill,  Johnson's  Cyclopaedia,  n,  1079. 

Au  order  of  Marsipobranchiates  distinguished  by  the  development  of  the  skull  and  the 
eoecal  nature  of  the  median  external  nasal  aperture;  no  duct  perforating  the  palate,  which 
is,  therefore,  left  entire  (whence  the  name).  The  branchial  apertures  are  on  each  side 
behind  the  head,  and  seven  in  number;  the  inner  branchial  duets  debouch  into  a  separate 
common  tube.  The  ova  are  small  and  superficially  like  those  of  fishes.  The  young  undergo 
a  complete  metamorphosis  after  leaving  the  egg.  The  larva'  have  an  elongated  slit-like 
mouth,  and  are  without  teeth  or  eyes.  In  this  condition  they  were  formerly  considered  to 
be  members  of  a  peculiar  group  (Ammocoetes).    At  maturity  the  mouth  is  circular,  surrounded

by  a  lip,  and  armed  with  dentigerous  lamella-  on  its  disk,  as  well  as  with  lingual  teeth; 
enlarged  plates  above  and  below  the  antrum  of  the  esophagus  have  been  called  maxillary 
and  mandibular,  but  they  have  no  hoinological  relation  with  the  upper  and  lower  jaws  of 
ordinary  fishes,  and  the  lower  jaw  in  them  is  absolutely  wanting. 

This  order  embraces  only  a  single  family  of  existing  species  (the  Petromyzontidce  or 
lampreys),  of  which  there  are  at  least  five  genera,  three  of  which  are  represented  in  North 
America.     (Gill.)

Dorsal  fins  two,  the  second  continuous  with  the  caudal;  maxillary  teeth  separate, 
pointed,  close  together,  not  forming  a  crescent-shaped  plate ;  mandibulary  plate  with  seven  to

Peiromyzon  americanus,  Le  Sueur,  Trans.  Am.  Phil.  Soe.,  i,  383. — Stoker,  Hist.  Fish.  Mass.,  251. 

Specimens  of  a  Petromyzon  apparently  not  specifically  distinct  from  P.  marinm,  have 
been  obtained  from  several  localities  at  considerable  depths.  The  Fish  Commission  trawled 
it  off  Cape  Ann  at  station  189,  in  85  fathoms,  and  at  192  in  100  fathoms,  and  also  at  station 
946,  off  Marthas  Vineyard  (lat.  39°  5.')',  Ion.  71°  14'),  at  a  depth  of  217  fathoms,  and  bottom 
temperature  of  17°.  The  occurrence  of  this  form  at  so  great  a  depth  is  interesting  in  con- 
nection with  the  record  of  the  following  species,  P.  Bairdii. 

PETKOMYZON  (Bathv.myzox)  BAIRDII,  Gill. 

Petromyzon  (Bathymyzon)  Bairdii,  Gill,  Forest  and  Stream,  xxi.  Ann.  30,  1883;   Proc.    U.  S.  Nat.Mus.,  vi, 
1883,  254. 

This  form  of  lamprey  was  described  by  Gill  from  a  single  specimen  (Nat.  Mus.,  No. 
33311),  obtained  by  the  U.  S.  Fish  Commission  at  station  2018  (lat.  40°  02'  00",  Ion.  68 
50'  30"),  at  a  depth  of  517  fathoms.     No  specific  characters  were  mentioned  except  those 
enumerated  above  under  the  generis-" diagnosis  -'supraoral  and  intraoral  plates  or  laminae 
destitute  of  odontoid  tubercles,  the  armature  of  the  lamprey  type  being  obsolescent."' 

The  form  is  very  closely  related  to  Petromyzon  marinus,  bat  the  limits  of  generic  and 
specific  variation  in  the  Hyperoartia  are  by  no  means  definitely  agreed  upon,  and  Gill's 
identification  of  this  specimen  is  accepted  without  comment  or  criticism. 

The  following  MS.  descriptions,  prepared  in  1883,  have  been  placed  in  our  hands  by  Dr. 
Gill: 

The  head,  from  the  snout  to  the  first  branchial  aperture,  is  contained  about  seven  times 
in  the  total  length,  while  the  eye  is  intermediate  between  the  snout  and  fifth  branchial 
aperture.  The  diameter  of  the  eye  is  equal  to  one-fourth  of  the  distance  of  the  interorbital 
area. 

The  diameter  of  the  circular  disk  equals  the  interval  between  the  eye  and  fifth  branchial 
aperture;  the  margin  is  regularly  fringed,  as  in  the  related  species. 

Indications  of  eight  teeth  are  on  the  infroral  lamina,  and  the  tips  of  the  two  suproral 
ones  are  barely  perceptible;  the  pectinations  of  the  lingual  teeth  are  well  marked  and 
differentiated. 

The  chest  (i.  e.,  space  between  first  and  seventh  branchial  apertures)  is  about  as  long 
as  the  snout. 

The  fins  are  moderate,  the  anterior  dorsal  being  somewhat  higher  in  front  of  the  middle 
than  the  diameter  of  the  orbit,  and  the  second  dorsal  about  twice  as  high  or  equal  to  the 
distance  between  the  eye  and  first  branchial  aperture.

The  color  is  dark,  except  upon  the  l>elly,  which  is  grayish.  The  second  dorsal  is  darker 
across  the  middle  infronl  and  towards  the  margin  behind,  while  the  caudal  is  blackish 
throughout.

This  hitherto  undescribed  form  is  evidently  most  closely  related  to  the  typical  species 
of  the  genus  Petromyzon,  but  differs  by  the  obsolescence  of  the  armature  of  the  suproral 
and  iufroral  lamina-,  while  differences  of  proportion  characterize  the  species;  it  is  scarcely 
generically  distinct  from  Petromyzon,  but  may  be  distinguished  as  a  subgeneric  type  under 
the  name  Bathymyzon    with  the  following  characters: 

BATHYMYZON. 

Petromyzontinm  with  the  suproral  lamina  contracted,  its  two  converging  teeth  almost 
completely  fused  together  and  only  evident  at  the  summit  of  the  combined  mass,  infroral 
lamina  crescentiforin  and  spout-like  at  the  middle,  and  with  the  denticles  obsolete,  discope- 
ripheral  teeth  numerous  and  in  obliquely-arched  series  of  4-7,  declining  downwards;  the 
innermost  lateral  teeth  of  the  four  rows  diverging  from  the  mouth,  in  each  side  bicuspid, 
with  the  cusps  approximated,  and  diminishing  downwards  rapidly;  the  lingual  teeth  3, 
pectinate,  the  anterior  deeply  impressed  and  sulcate  backwards  at  the  middle  and  the  pos- 
terior correspondingly  curved  backwards  at  their  inner  lateral  angles;  the  anterior  dorsal 
tin  distinct  from  posterior.      (6ill,  MS.) 


Class  ELASMOBRANCHIL 

Lyriferous  vertebrates  with  cartilaginous  skeleton,  and  destitute  of  membrane  or  der- 
mal bones;  no  cranial  sutures.  Body  with  vertical  and  paired  fins,  the  posterior  pair  ab- 
dominal; caudal  tin  with  elongated  upper  lobe;  gills  attached  by  their  outer  edges  to  the 
skin,  with  an  intervening  gill  opening  between  each;  no  gill  cover;  skin  naked  or  covered 
with  minute  imbricated  scales  or  hard  plates,  sometimes  spinous;  no  air  bladder;  arterial 
bulb  with  three  series  of  valves;  intestines  with  a  spiral  valve;  optic  nerves  united,  not 
decussating,  or  only  slightly  so;  ova  few  and  large,  fertilized,  and  sometimes  developed 
internally;  embryo  with  external  deciduous  gills;  males  with  intromittent  organs  attached 

to  ventrals.

The  Nurse  Shark  belongs  to  the  northern  parts  of  the  North  Atlantic  and  the  Arctic 
Ocean.  Twenty  or  more  have  been  taken  about  the  British  Isles  within  the  past  century, 
chiefly  along  the  northern  shores,  though  one  has  been  seen  off  Suffolk,  and  one  in  L832  was 
found  in  the  estuary  of  the  Thames.  In  the  western  Atlantic  it  has  not  been  seen  south  of 
Cape  Cod.  Three  came  ashore  at  Provincetown  in  1848-49,  one  at  Portland,  Me.,  in  1S4(>, 
and  one  about  Cape  Ann  before  1818,  when  Le  Sueur  saw  and  described  its  stuffed  skin  at 
Marblehead.  About  Greenland  it  is  frequent  near  the  shores,  as  it  is  also  off  Iceland  and 
Norway,  and  the  jaws  are  often  seen  in  ethnographical  collections,  being  used  by  the  Eski- 
mo to  make  a  rude  tiara-like  headdress.  Curiously  enough,  this  sluggish  shark  is  a  deter 
mined  enemy  of  the  whale,  and  bites  great  lumps  of  flesh  from  its  body,  as  Scoresby  has 
recorded  in  his  "Arctic  Regions." 

Somniosus  descends  to  considerable  depths,  and,  as  Liitken  has  shown,  deposits  its 
numerous  soft,  globular  eggs,  devoid  of  protective  covering,  in  the  soft  mud  in  the  bottom 
of  the  deep  sea. — (Liitken,  Vid.-Medd..  1879-'80,  pp.  56-61.  Zoological  Record.  1S74.  Day,

Somniosus  rostratus  (Scymnus  rostratus,  Risso= Loemargus  rostratus,  Canestrini),  is  a 
form  recognized  by  Italian  naturalists  from  a  very  few  individuals  observed  about  Nice  and 
Genoa.     It  lives  a  grande  profondita  (Canestrini)  and  attains  the  length  of  10  decimeters.

region  have  been  made  at  all  seasons  of  the  year,  it  would  appear  that  its  breeding  place 
and  home  is  in  the  northeastern  Atlantic,  and  that  its  infrequent  capture  is  due  to  its  habit 
of  living  on  the  offshore  ledges  and  banks  at  considerable  depths.  As  the  synonymy  shows, 
it  was  recorded  by  Smith  from  the  Cape  of  Good  Hope.  It  may  be  regarded  as  peculiar  to 
the  eastern  pari  of  the  Atlantic  Hasin,  the  Cape  Cod  specimen  being  doubtless  a  waif.

Spinaci&a,  GOnther,  Cat.  Fish.  Brit.  Mus..  vm,  1870,  U7-425.— Jordan  and  Gilbert,  Bull,  xvi,  U.  8.  Nat. 
Mus.,  1883,  15. 

Selachians  with  body  somewhat  elongate  and  head  depressed;  eyes  lateral;  nictitating 
membrane  absent;  mouth  inferior,  rather  large,  with  a  deep  groove  along  either  side;  teeth 
compressed,  varied;  nostrils  inferior,  lateral,  near  the  front  margin  of  the  snout;  spiracles 
moderate;  gill  openings  moderate,  five  on  each  side  and  all  in  front  of  the  pectoral  tins: 
dorsal  tins  two.  each  armed  with  a  spine;  the  first  dorsal  in  front  of  the  pectorals;  anal  tin 
lacking;  caudal  tin  with  the  lower  lobe  small  or  obsolete;  ventials  far  back. 

Of  the  seven  genera  comprising  this  family  only  two,  Squalus  (=AcantMas)  and  Oxy- 
notus  {=Gentrina),  are  shallow-water  forms.  Of  these,  all  the  species  are  represented  in 
the  Mediterranean.  The  family  Spiitacidw  is  peculiarly  characteristic  of  the  Mediterranean 
fauna,  all  known  species  except  three,  one  of  which  is  from  the  northwestern  Atlantic  and 
two  are  from  Japan,  occurring  in  that  sea  or  waters  immediately  adjacent.  Squalus  is  the 
most  cosmopolitan  of  the  genera,  but  does  not  enter  the  North  Pacific. 

The  deep-sea  forms  of  these  little  sharks  are  especially  abundant  in  the  great  depths 
outside  the  entrance  to  tin'  Mediterranean,  where  an  extensive  fishery  is  carried  on.

The  little  spinous  dogfish  with  tricuspid  teeth  in  its  upper  jaws  has  not  yet  been 
found  in  the  western  Atlantic.  Unless  the  naturalists  of  Europe  have  been  careless, 
its  distribution  on  that  coast  is  very  remarkable.  The  Norwegians  find  it  along  theirentire 
coast,  from  the  Christiania  Fiord  to  West  Fimnark  (kit.  <i'J°  30'),  where  it  is  abundant  and 
produces  young  in  midsummer.  In  the  Mediterranean  it  is  also  abundant,  occurring  at 
great  depths  (dbita  agrande  prqfondita,  Canestrini),  and  it  has  also  been  taken  in  the  Atlantic 
off  Lisbon.  We  can  find  no  record  of  its  Inning  been  observed  by  French  or  English  nat- 
uralists, unless  it  has  been  confounded  with  the  other  form  of  spiny  dogfish — Squalus 
acanthias,L., — which  is  abundant  at  both  extremes  of  the  recorded  range  of  Spinax  spinax, 
and  is  abundant  in  the  Mediterranean  as  well  as  in  Norway,  and  also  on  the  American 
coast  from  New  York  (hit.  40°  30')  northward  to  Labrador  and  doubtless  to  Greenland,  It  is 
probable  that  a  more  careful  search  may  reveal  the  presence  of  Spinax  on  the  English  and 
French  coasts,  and  it  may  be  in  America. 

Etmopterus  spinax  is  replaced  about  Madeira  by  E.pusillus.

The  Blale  took  a  single  individual,  believed  to  belong  to  this  species,  at  Station  CVIH, 
off  St.  Christopher,  in  208  fathoms.  It  had  previously  been  known  only  from  Madeira  and 
Cuba,  the  Cape  Verdes,  200  fathoms  (Travailleur),  and  the  Bermudas  (Goode).  Lowe  had 
five  or  six  from  Madeira,  where  it  is  not  very  rare,  never  exceeding  a  foot  in  length.  The 
species  is  there  taken  "  at  moderate  depths."  but  the  line  fisheries  of  Madeira  are  all  at  extra- 
ordinary depths  below  the  surface.

Body  somewhat  rounded,  covered  with  minute  stellate  scales;  dorsal  tins  short,  each 
preceded  by  a  strong  spine;  teeth  in  both  jaws  tricuspid,  small;  color,  dark  brown. 

This  little  shark,  previously  known  only  from  the  coast  of  Greenland,  has,  since  L878, 
been  found  to  be  common  on  the  offshore  banks  at  depths  of  150  or  more  fathoms  in  com- 
pany with  Centroscymnus.  Vaillanfs  assignment  of  a  specimen  from  the  Banc  d'Arguin, 
750  fathoms,  to  this  species,  is  at  best  very  questionable. 

A  young  individual,  probably  G.  Fabrieii,  was  taken  at  station  2377,  February  11. 
188.3.  Colors:  "All  the  tins  whitish,  except  caudal,  which  is  yellowish;  dorsals  with  a  nar- 
row black  stripe  anteriorly:  tip  and  lower  lobe  of  caudal  with  very  broad  black  margin; 
iris  greenish  golden;  sides  with  several  lines  made  up  of  dark  dashes."

This  form  is  evidently,  as  Dr.  Gunther  indicates,  very  closely  allied  to  Centroseyllium 
Fabrieii,  having  the  same  disposition  of  the  tins,  size  of  teeth,  and  dorsal  spines,  but  the 
epidermoid  productions  of  the  head  and  body  are  much  coarser  and  in  the  form  of  granula- 
tions, whilst  in  Centroseyllium   Fabrieii  they  are  minute. 

One  specimen,  11  inches  long,  badly  mutilated,  was  obtained  by  the  Challenger  at

The  labial  fold  extends  for  some  distance  aloug  the  margin  of  the  jaws.  Snout  spatulate, 
much  produced,  the  distance  between  the  nostrils  being  less  than  one-third  of  the  length  of 
the  prseoral  portion  of  the  snout.  Lower  angle  of  the  pectoral  flu  rounded,  not  produced; 
the  length  of  the  bases  of  the  two  dorsal  flits  (without  the  spines)  is  nearly  equal,  and  one- 
half  of  the  distance  between  them;  extremity  of  the  ventral  fins  below  the  middle  of  the 
second  dorsal  fin.  The  scutes  arc  small,  tricuspid,  and  so  minute  as  to  give  a  velvety  appear- 
ance to  the  skin.     (Oiinthcr.) 

This  form  occurs  off  the  coasts  of  Portugal  and  Madeira.

Labial  groove  prolonged  forwards,  but  separated  by  a  broad  space  from  that  of  the 
other  side.  Upper  teeth  very  small,  narrow  and  lanceolate.  The  distance  between  the  nos- 
trils is  rather  less  than  one-half  the  length  of  the  prseoral  portion  of  the  snout.  Lower  angle 
of  the  pectoral  rounded,  not  produced.  Dorsal  fins  short,  especially  the  first,  the  length  of 
which  (without  the  spine)  is  only  about  one  sixth  its  distance  from  the  second;  extremity  of 
the  veutrals  below  the  end  of  the  second  dorsal.  Scales  on  the  heail  and  nape  with  striae; 
the  others  smooth,  with  a  depression  at  the  base.     Uniform  blackish  brown.     (Oilnther.) 

Capello  records  the  species  from  Setubal,  and  J.  Y.  Johnson  obtained  an  example  from 
the  sea  of  Madeira.  The  species  is  abundant  on  the  offshore  banks  of  New  England,  at  the 
depth  of  200  fathoms  and  more.     It  is  ovoviviparous,  like  Squalus. 

The  naturalists  of  the  French  expedition  made  some  very  interesting  observations  upon 
the  breeding  habits  of  this  shark,  iu  August,  1881.  .Most  of  the  females  were  in  condition  of 
gestation.  The  number  of  youug  varied  from  thirteen  to  fifteen.  These  were  of  various 
sizes — from  10  to  160  millimeters — and  Vaillant,  in  his  report  (p.  60),  gives  interesting 
details  concerning  them.  It  is  the  idea  of  Vaillant  that  these  females,  at  the  approach  of 
the  breeding  season,  come  nearer  to  the  surface  of  the  water  iu  order  to  find  a  greater  heat. 
the  temperature  at  the  great  depths  where  they  are  supposed  ordinarily  to  live  not  being 
sufficient  to  develop  the  youug.  He  remarks,  however,  that  the  specimens  taken  near 
Setubal,  in  deeper  water  were  evidently  very  near  the  period  of  parturition,  and  that  it  is 
evident  that  the  removal  to  warmer  temperature  is  not  always  indispensable. 


DISCISSION    OP    SPECIES    AND    THEIR    DISTRIBUTION.  15 

Dr.  E.  Percival  Wrighl  reported  to  Dr.  G-unther  that  he  had  seen  the  Portuguese  fish- 
ermen capturing  this  form  at  a  depth  of  400  or  500  fathoms,  with  hand  lines  2,400  feet  in 
length,  and  that  they  came  from  the  same  depth  with  Hyalonema. 

Gentroscymnus  obscurus,  Vaillant  (Voy.  Travailleur  e1  Talisman,  67,  pi.  n.  fig.  2),  is 
doubtfully  assigned  to  this  genus,  having  close  affinities  also  with  Centrophorus.  It  was 
taken  off  Soudan  in  200  fathoms  and  below.

The  Centrina,  called  in  Italy  " pesce-porco,"  upuerco"  and  "pourc-marm,"  in  Por- 
tugal " peixe-porco„'n  in  France  ••  humantin,,'"  is  not  unusual  in  the  Mediterranean,  and  indi- 
viduals have  been  taken  at  considerable  depths  on  the  Setubal  banks,  by  Portuguese  natural- 
ists, while  Moreau  records  a  straggler  from  the  mouth  of  the  Loire.  In  1*77  one  was  taken 
in  2(3  fathoms  off  the  coast  of  Cornwall,  and  in  past  years  the  species  appears  to  have  strayed 
as  far  north  as  Cornwall. 

Its  claim  to  a  position  among  the  dee])  sea  lishes  is  doubtful,  but  in  the  opinion  of  some 
ichthyologists  it  is  an  inhabitant  of  great  depths. 

It  has  never  been  found  outside  of  the  northwest  Atlantic. 

Family   SCYLLIORHINID^E. 

Scylliidce,  GOnthkr,  Cat.  Fish.  Brit.  Mus..  vni,  1870,  400. — Gill,  Fam.  Fishes,  24. — Day.  Fishes  (it.  Britain

A  family  of  sharks  distinguished  by  the  position  of  their  dorsal  fins  and  their  laying- 
eggs  like  those  of  tin'  rays.  The  body  is  more  elongated  than  in  the  sharks  generally;  the 
scales  developed,  as  fine  shagreen;  the  head  depressed  and  oval:  the  nostrils  with  large  flaps; 
the  mouth  inferior  and  arched  ;  the  teeth  small  (several  series  being  in  use  at  the  same  time), 
compressed,  and  cuspidate;  branchial  apertures  five,  the  posterior  of  which  are  above  the 
pectorals;  spiracles  behind  the  eyes  well  developed;  dorsal  tins  two,  the  anterior  above  or 
behind  the  ventrals;  anal  fin  present,  variable  in  position ;  caudal  tin  extended  toward  the 
end  of  the  tail,  and  with  the  lower  lobe  little  produced  downward  at  its  front  margin:  pec- 
torals moderately  developed  and  with  rounded  angles.

The  family,  as  thus  defined,  embraces  Scyllium,  Pristiurus,  Stegostoma,  Parascyllium, 
Chiloscyllium,  and  related  genera.  They  are  inhabitants  entirely  of  the  sens  of  the  Old 
World  and  Australia,  none  being  found  in  American  waters.  They  are  among  the  lew- 
sharks  which  lay  eggs  iuvestedin  parchment-like  eases,  like  those  of  the  rays.

Body  moderate,  portion  behind  the  vent  longer;  head  depressed,  width  nearly  equal  to 

its  length  in  front  of  the  spiracles.  Distance  across  the  head  at  anterior  angles  of  eyes,  from 
angle  of  eye  to  end  of  snout,  between  angles  of  mouth,  between  outer  angles  of  nostrils,  or 
between  angle  of  nostril  and  that  of  month,  about  equal.  Shape  of  body  similar  to  thai  of 
S.  canicula.  Snout  moderate,  length  from  mouth  less  than  the  distance  between  the  outer 
margins  of  the  nostrils.  Nasal  valves  separated  by  an  interspace  of  less  than  their  width, 
not  reaching  the  mouth,  somewhat  folded,  without  a  free  cirrus.  Mouth  medium;  the  height 
of  the  irregular  arch  formed  by  its  outline  is  little  more  than  half  its  width.  Labial  fold 
on  lower  jaw  extending  nearly  one-fourth  of  the  distance  to  the  symphysis;  fold  on  upper 
jaw  rudimentary.  Teeth  small,  alike  on  upper  and  lower  jaws,  bearing  a  sharp  central 
cusp,  on  each  side  of  which  are  two  smaller  ones,  several  series  in  function  at  the  same 
time.  No  nictitating  membrane.  Spiracles  small.  Gill  openings  small,  fourth  and  tilth 
over  the  base  of  the  pectoral.  Pectorals  moderate,  broad,  short,  anterior  margins  curved, 
extremities  rounded.  Veutrals  rather  small,  united  for  a  short  distance  behind  the  claspers, 
outer  extremity  broadly  rounded,  posterior  angle  acute.  First  dorsal  much  larger  than  tin- 
second,  about  twice  the  length  of  its  base  in  advance  of  the  latter,  extending  forward  above 
the  free  portions  of  the  veutrals,  insertion  very  near  the  middle  of  the  total  length.  Second 
dorsal  smaller  than  the  anal,  which  extends  below  the  anterior  half  of  its  entire  length,  not 
reaching  the  caudal.  Caudal  not  large,  a  shallow  notch  between  its  upper  and  lower 
lobes,  upper  slightly  indented  on  its  hinder  margin.  Scales  of  shagreen  small,  unequal:  on 
those  of  the  back  there  are  three  or  five  carina;,  the  median  of  which  is  prolonged  into  an 
acute  point. 


DISCISSION    OP   SPECIES    AND    THEIR    DISTRIBUTION.  17 

Light  brownish,  or  reddish  brown,  crossed  at  irregular  intervals  by  groups  of  two  to  four 
narrrow  black  lines  which  arc  joined  toward  the  Banks  by  short  lines  in  such  manner  as  to 
inclose  polygonal  spaces,  thus  forming  a  network  in  which  the  meshes  vary  exceedingly  in 
size  and  shape.     Uniform  light  yellowish  below. 

Total  length,  12.25;  snout  to  vent,  5.75  inches. 

One  specimen  was  obtained  by  the  Blake,  lat.  38°  22'  35"  X..  long.  73  33'  40"  W.;  89 
fathoms.     The  Fish  Commission  has  since  obtained  several  others. 

A  young  individual,  (i  inches  in  length,  was  obtained  by  the  Blake  off  Barbados,  at 
Station  evil,  at  a  depth  of  200  fathoms,  the  coloration  of  which  is  so  unlike  that  of  the  typi- 
cal 8.  rr/iY'crthat  at  first  sight  it  would  seem  to  belong  to  quite  a  different  form,  but  a  study 
of  its  coloration  reveals  a  general  correspondence  with  the  specimen  described  by  Garman. 
The  reticulations  are  scarcely  visible,  and  the  spaces  between  the  lines  at  the  base  of  each 
of  the  dorsal  tins  are  tilled  by  a  shading  of  uniform  brown  reenforced  by  darker  blotch-like 
lines,  and  a  similar  transformation  is  observable — two  blotches  on  the  tail  and  three  in 
advance  of  the  first  dorsal,  as  well  as  upon  the  base  of  the  pectorals  and  in  a  spot  upon  each 
side  midway  between  the  extremity  of  the  pectoral  and  the  base  of  the  anal.  Approxi- 
mately in  the  track  of  the  narrow  lines  observable  in  Carman's  specimen  may  be  found 
various  spots  and  blotches  of  blackish  brown,  so  that  at  first  sight  it  gives  the  impression 
of  being  covered  with  blotches  rather  than  with  reticulations. 

It  was  at  first  our  intention  to  describe  this  as  a  separate  species  under  the  name  of  8.  boa, 
but  it  is  doubtful  if  it  can  be  regarded  even  as  a  color  variety,  the  markings  being  doubtless 
due  to  immaturity.

Nasal  valves  confluent,  with  a  short  blunt  cirrus  on  the  posterior  as  well  as  on  the 
anterior  flap,  being  nearly  opposite;  the  length  of  nasal  cavity  about  equal  to  the  horizontal 
diameter  of  the  eye,  the  two  cavities  separated  l>y  a  space  ecpial  to  half  that  of  the  inter- 
orbital  area,  and  two-fifths  the  length  of  the  snout ;  the  distance  of  the  posterior  angle  of 
the  nasal  cavity  from  the  root  of  the  teeth  at  the  nearest  point  equal  to  half  the  area 
between  the  cavities;  distance  from  the  symphysis  to  the  tip  of  the  snout  ecpial  to  the  width 
between  the  angles  of  the  mouth.  A  well-developed  labial  fold  at  the  angle  of  the  mouth, 
extending  on  the  lower  jaw  halfway  from  its  angle  to  the  symphysis,  and  on  its  upper  jaw 
nearly  in  the  direction  of  the  nasal  cavity,  disappearing  at  half  the  distance.  Teeth  moder- 
ate, with  two  small  lateral  cusps  on  each  side  of  the  longer  middle  cusp,  in  about  five  rows. 
Gill  openings  narrow,  somewhat  less  than  the  long  diameter  of  the  eye;  the  distance  from 
the  anterior  opening  to  the  last,  which,  like  the  fourth,  is  above  the  angle  of  the  pectoral 
tin,  is  equal  to  half  the  length  of  the  snout.  Ventral  fins  thick,  short,  leaf-shaped,  their 
origin  twice  as  far  from  the  nasal  cavity  as  is  the  last  of  the  gill  openings.  The  origin  of  the 
anal  fill  under  the  tip  of  the  first  dorsal,  and  its  end  under  the  end  of  the  dorsal;  its  base 
equal  to  half  the  length  of  the  head  (without  the  gill  openings),  nearly  equal  to  the  com- 
bined leugth  of  the  bases  of  the  two  dorsals.  Caudal  continued  in  the  line  of  the  axis  of 
the  body;  lower  lobe  rounded,  and  in  its  greatest  height  not  deeper  than  the  height  of  the 
caudal  extension  of  the  body  at  the  same  point.     Color,  uniform  grayish  brown.

S.  Nat.  Miis..  1S83,  147. 

The  following  description  and  table  of  measurements  are  from  Dr.  Bean's  account  of 
the  species: 

The  greatest  height  of  the  body  is  at  the  origin  of  the  first  dorsal;  it  is  contained  eight 
and  three  sevenths  times  in  the  total  length.  The  height  at  the  origin  of  ventrals  is  con- 
tained nine  and  one  half  times  in  total  length.  The  height  ot  head  at  the  first  gill  opening 
is  a  little,  greater  than  that  of  body  at  the  ventral  origin,  while  the  height  of  the  head  at 
the  angle  of  the  mouth  is  a  little  less  than  one-eleventh  of  the  total  length.  The  least 
height  of  the  tail  equals  the  height  of  the  anal,  ami  is  contained  twenty-five  times  in  total 
length. 

The  head  is  somewhat  depressed  in  front,  with  moderately  sharp  snout,  which  is  nearly 
twice  as  long  as  the  distance  of  its  tip  from  the  mouth.  The  distance  from  snout  to  last 
gill  opening  is  contained  live  times  in  total  length.  The  distance  from  snout  to  first  gill 
opening,  measured  horizontally,  equals  twice  the  height  of  body  at  origin  of  second  dorsal. 
The  distance  between  the  first  and  hist  gill  openings  equals  nearly  twice  the  length  of  the 
eye.  The  height  of  the  first  gill  opening  is  about  equal  to  the  distance  between  the  angle 
of  the  mouth  and  the  spiracle.  The  height  of  the  head  at  angle  of  mouth  is  contained 
eleven  times  and  at  the  first  gill  opening  nine  times  in  total  length.  The  length  of  the 
snout  equals  one-half  the  body  height  at  origin  of  first  dorsal.  The  distance  of  mouth 
from  snout,  measured  on  the  axis  of  the  fish,  equals  one-third  width  of  mouth.  The  dis- 
tance from  snout  to  angle  of  mouth,  obliquely  taken,  equals  oue-fourth  the  distance  from 
snout  to  last  gill  opening.  The  distance  between  eye  and  spiracle  equals  that  from  mouth 
to  nostril.  The  distance  from  angle  of  mouth  to  spiracle  is  about  equal  to  height  of  first 
gill  opening.  The  spiracle  is  moderately  large,  the  length  of  its  opening  being  contained 
twice  in  the  height  of  fourth  .nill  opening.  The  oblong  eye  is  placed  near  the  dorsal  profile; 
the  length  of  the  orbit  is  about  one  half  the  greatesl  height  of  second  dorsal:  the  length  of 
the  eve  equals  about  one-fourth  width  of  mouth.  The  length  of  upper  jaw  is  slightly  more 
than  that  of  lower,  and  nearly  equals  the  distance  between  the  spiracles.  The  distance 
from  the  mouth  to  the  nostril  is  about  one  fourth  least  height  of  tail;  the  distance  between 
nostrils  equals  four  times  the  distance  from  eye  to  spiracle.  The  interorbital  space  equals 
one-half  the  length  of  second  dorsal  base.  The  distance  between  the  spiracles  equals  four 
times  their  greatest  length. 

The.  first  dorsal  is  very  long  and  low,  highest  behind  its  middle,  the  length  of  its  base 
equal  to  seven  times  its  greatest  height;  its  distance  from  the  snout  is  a  little  more  than 
twice  the  greatest  length  of  pectoral.  The  secoud  dorsal  is  distant  from  the  end  of  the  first 
a  length  equal  to  nearly  twice  its  greatest  height;  the  length  of  its  base  is  somewhat  more 
than  the  body  height  at  origin  of  first  dorsal. 

The  second  dorsal  begins  at  a  distance  from  the  end  of  the  first,  equal  to  the  height  of 
body  at  ventral  origin;  the  length  of  its  base  equals  twice  the  interorbital  distance;  its 
height  equals  nearly  twice  the  length  of  the  orbit. 

The  anal  is  entirely  under  the  secoud  dorsal,  but  its  base  is  a  little  less  than  five-sev- 
enths as  long  as  that  of  the  latter;  the  greatest  height  of  the  anal  equals  the  least  height 
of  caudal  peduncle. 


DISCUSSION    OF    SPECIES    AND    THEIR    DISTRIBUTION. 


19 


The  caudal  originates  at  a  distance  from  the  end  of  the  second  dorsal  about  equal  to 

the  height  of  the  anal;  it  is  divided  by  a  notch  into  a  short  upper  portion,  whose  length*  is 
very  little  more  than  the  greatest  height  of  first  dorsal,  and  a  very  low  and  long  lower  por 
tion,  the  longest  margin  of  which  is  nearly  twice  as  long  as  the  snout.  The  distance  of  the 
caudal  from  the  end  of  anal  base  equals  one-fourth  the  length  of  second  dorsal  base. 

The  distance  of  pectoral  from  snout  is  contained  five  times  in  total  length;  the  length 
of  pectoral  equals  nearly  twice  the  width  of  its  base,  and  is  a  little  more  than  one-ninth  of 
total  length.     The  greatest  width  of  pectoral  equals   twice   the  height  of  anal,  and  is  eon 
tained  twelve  and  one  third  times  in  total  length. 

The  origin  of  the  ventral  is  slightly  in  advance  of  the  end  of  first  dorsal,  and  is  behind 
the  middle  of  total  length  a  distance  equal  to  the  interoibital  space.  The  length  of  ventral 
equals  that  of  lower  jaw.  The  width  of  ventral  base  equals  that  of  pectoral  base;  the great- 
est width  of  ventral  slightly  exceeds  its  length. 

Color. — When  received  the  margins  of  the  tins  were  apparently  faded:  the  original 
color  was  probably  grayish  brown  with  dark  margins  on  all  the  fins  except  the  first  dorsal. 
Gapello  states  that  his  example  was  chestnut-brown. 

The  National  Museum  received  February  12,  1883,  in  the  fresh  state,  a  fine  example  of 
a  species  of  Pseurlotriiiris,  which  came  ashore  at  the  Amaganseft  Life-Saving  Station  on 
Long  Island,  February  8,  l.ss:3,  forwarded  by  Mr.  J.  15.  Edwards,  keeper  of  the  Suffolk 
Life-Saving  station.     [The  specimen  is  the  one  here  described.] 

No  species  of  the  genus  Pseudotriacis  has  heretofore  been  recorded  in  the  western  At- 
lantic. 

The  gills  and  mouth  were  obstructed  by  sand.  The  only  parasites  discovered  on  the 
animal  were  a  couple  of  isopods,  one  of  which  was  found  in  the  eye  cavity.

Scyllium  acanthonotum,  Dkfil.  and  Ver.  (young  specimen,  fide  Giglioli). 

A  Pristiurus  with  the  nasal  valves  separated  by  a  broad  interval  and  placed  nearer  to 
the  mouth  than  to  the  end  of  the  snout;  a  short  labial  fold  round  the  angle  of  the  mouth. 
Dorsal  tins  subequal  in  size,  the  second  above  the  hinder  part  of  the  anal;  anal  flu  nearly 
as  long  as  the  head  to  the  first  gill  opening;  upper  parts  with  rounded  darker  spots  of  vari- 
ous sizes,  each  with  a  lighter  margin.     (Giinther). 

Pristiurus  claims  a  place  among  deep-sea  fishes  on  account  of  its  captures  near  Tromsoe, 
at  a  depth  of  250  fathoms.  The  species  is  abundant  on  the  coast  of  Norway,  as  far  north  as 
Tiondhjems  Fiord  (hit.  63°  30'),  where,  according  to  Storm,  it  is  found  in  considerable  depths 
(hit,  70°).  if  is  ,.,,!.,.  on  Ohristiania  Fiord  (lat.  58°).  Farther  south  it  is  a  littoral  form, 
occurring  at  Madeira  and  also  in  the  vicinity  of  Lisbon,  where  it  is  rare  and  is  called 
Leitao  or  Litao.  It  is  the  "Eyed  Dogfish"  of  Couch  and  Yarrell,  who  have  recorded  a 
single  specimen  (25  inches  long)  from  the  coast  of  Cornwall,  taken  by  a  line  fisherman 
off  Polperro,  in  1837. 


DISCUSSION    OP    SPECIES   AM)    THEIR    DISTRIBUTION.  21 

In  llic  Mediterranean  it  is  found  :it  considerable  depths.  In  July,  is~!».  Prof.  Giglioli, 
fishing  off  Genoa  with  trawl  lines,  took  50  individuals  at  depths  of  mo  to  500  fathoms.

Priatiurut  atlanticus,  Vmii.ixi.  Exp.  Scient,  Trav.  el  Tal.,  1888,  59,  pi.  r,  iiur.  I. 

A  Pristiurus  closely  resembling  /'.  melastomus,  Rafinesque,  but  with  its  snout  some- 
what more  obtuse,  its  length  from  the  extremity  of  the  upper  lip  being  less  than  the  dis- 
tance between  the  labial  commissures,  while  in  the  other  species  it  is  equal  or  greater.     The 

teeth  are  somewhat  stouter,  less  elongate,  ami  on  their  sides  are  two  dent  ieiilat  inns  instead 

of  the  single  one.  They  also  appear  to  be  more  numerous — 31  on  each  side  of  the  upper 
jaw,  in  place  of  lis  in  /'.  mclanostomus.  The  cutaneous  plates,  although  similar  in  character 
and  very  like  in  form,  have  the  margin  proportionately  narrower,  and  the  middle  rib  more 
narrow  and  salient,  the  lateral  teeth  being  less  divergent.  The  branchial  openings  decrease 
in  width  posteriorly,  the  last  not  more  than  halt' the  height  of  the  first;  while  in  /'.  melanos 
tomus  it  is  at  least  three-fourths. 

The  above  description  is  a  translation  of  the  description  by  Vaillant.  who,  though 
admitting  that  the  differences  taken  singly  are  slight,  considered  that  taken  together  they 
impart  to  the  animal  a  peculiar  physiognomy,  and  that  the  comparison  of  a  number  of 
specimens  of  the  same  size  seemed  to  him  to  justify  the  establishment  of  a  new  species. 

Vaillant  is  of  the  opinion  that  possibly  this  form  may  be  that  described  by  Lowe  from 
Madeira,  under  the  name  Pristiurus  melanostomus. 

A  single  female,  440  millimeters  in  length,  was  taken  at  a  depth  of  540  meters  off  Cape 
Spartel.  from  Station  VIII  of  the  French  expedition.

small;  teeth  in  six  or  seven  rows  in  each  jaw,  about  two  hundred  in  each  row;  first  dorsal 
large,  triangular,  over  the  space  between  pectorals  and  veutrals ;  second  dorsal  much  smaller, 
rather  larger  than  anal ;  tail  large. 

This  giant  selachian  appears  to  be  most  abundant  in  the  far  north.  It  is  not  unusual 
about  the  British  Isles,  especially  around  Scotland  and  the  Orkneys.  Its  capture  is  very 
unusual  in  the  Mediterranean,  but  in  Norway  it  is  the  occasion  of  a  considerable  fishery 
on  account  of  its  liver.  In  the  northwestern  Atlantic  it  is  rare,  though  sometimes  encoun- 
tered by  the  Gloucester  fishermen,  where  they  capture  it  for  its  liver,  as  is  done  in  Norway. 
Prof.  Verrill  has  recorded  the  occurrence  in  the  summer  of  1S70,  at  Eastport,  Me.,  of  there 
specimens  25  to  •'!<>  feet  in  Length,  and  one  previously  taken  in  1S6S,  which  measured  35 
feet.  Mitchill,  writing  in  L814,  spoke  of  its  occasional  occurrence  at  Provincetown.  Storer 
mentions  a  specimen  measuring  •"><•  feet  3  -inches,  harpooned  in  Provincetown  Harbor  in  1839. 

It  is  unknown  elsewhere  than  in  the  North  Atlantic,  and  south  of  the  Grand  Banks  on 
the  west  and  Scotland  on  the  east  may  be  regarded  as  an  estray.  To  what  extent  it  fre- 
quents the  depths  is  unknown,  but  since  the  young  have  never  been  seen  it  is  believed  to 
breed  in  deep  water.

Body  very  long,  slender,  eel-like,  increasing  in  size  comparatively  little  anteriorly,  com- 
pressed near  and  behind  the  vent,  which  is  in  the  posterior  half  of  the  total  length.  Head 
broad,  wider  than  high.  Crown  slightly  convex,  forming  a  rather  sharp  angle  with  the 
snout  and  sides  of  the  head  from  the  eyes  forward.  Skull  with  an  anterior  foramen,  begin- 
ning a  short  distance  in  front  of  a  vertical  from  the  front  edge  of  the  orbit,  resembling  that 
of  Raja.  Behind  this,  midway  between  the  eyes,  there  is  an  elongate  depression  on  the 
crown  as  of  a  second  foramen,  while  on  the  occiput,  a  little  distance  in  front  of  the  occipital 
pores,  a  deep,  rounded  depression  indicates  what  is  commonly  called  the  second,  the  poste- 
rior foramen.     Snout  broad,  rounded,  hardly  extending  in  front  of  the  jaws,  rather  acute.

angled  or  shovel-shaped  at  the  top.  Nostril  moderate,  vertical,  separated  by  a  fold  from 
each  side  into  an  upper  opening  looking  forward  and  a  lower  one  looking  backward,  situated 
about  midway  from  eye  to  end  of  snout  and  near  the  middle  of  the  space  from  top  of  head 
to  month.  Eye  moderately  large,  orbil  elongate,  near  a  vertical  from  the  middle  of  the 
length  of  the  month,  spiracle  very  small,  over  the  hyomandibular;  its  distance  behind  the 
eye  equal  to  thai  from  eye  to  end  of  snout.  Mouth  cleft  very  deep,  slightly  curved,  extend- 
ing as  far  back  as  the  skull.  Hoof  and  door  of  mouth  covered  with  sharp  scales,  the  former 
curving  upward  very  strongly  behind  the  teeth  between  the  nostrils.  Upper  and  lower 
jaws  about  equal  in  length.  Lips  without  a  groove  or  labial  fold.  Glossohyal  cartilage 
(basihyal)  prominent  above  the  floor  of  the  mouth  and  free  at  its  extremity  about  half  an 
inch,  forming  a  tongue.  Teeth  small,  similar  in  both  jaws,  several  in  each  row  in  function 
at  the  same  time,  each  with  three  long,  smooth,  curved,  backward  directed,  slender,  very 
sharp  cusps,  each  of  which  bears  some  resemblance  to  a,  serpent's  tooth.  A  small  cusp  on 
the  base  at  each  side  of  the  central.  Bases  of  teeth  broad,  extending  inward  about  the 
length  of  the  cusps,  terminating  in  two  prongs  which,  extending  beneath  the  base  of  the 
next  tooth,  prevent  the  possibility  of  reversion  or  turning  the  cusps  forward.  Fourteen 
rows  of  teeth  on  each  side  on  the  upper  jaws,  no  median  series.  A  median  row  on  the  s\  m 
physis  of  the  lower  jaws,  its  teeth  similar  in  size  and  shape  to  those  of  the  thirteen  rowson 
each  side  of  it.  Hyomandibular  and  ceratohyal  closely  and  somewhat  firmly  connected 
with  the  jaws  at  the  hinge  or  hinder  angle  of  the  latter.  Branchial  arches  long,  very  slen- 
der, with  sharp  small  scales  on  their  inner  edges.  Without  dissecting,  twenty-two  branchial 
rays  can  be  counted  on  the  hyomandibular  and  ceratohyal  (the  first  arch)  and  on  the  suc- 
ceeding six  arches  in  order,  15,  14,  12,  !t,  <>,  and  0,  respectively.  In  most  cases  the  outer 
extremities  of  the  rays  are  produced  in  a  sharp,  flexible  point  beyond  the  adjacent  margin 
of  the  gill  covers.  Gill  openings  very  wide,  oblique,  the  opposite  series  very  narrowly  sepa- 
rated on  the  throat,  the  fourth  in  front  of  a  vertical  from  the  pectoral  and  the  tift  h  and  sixth 
extending  back  above  the  shoulder.  A  broad  opercular  flap  covers  the  first  branchial  aper- 
ture and  is  continuous  and  free  across  the  isthmus,  forming  a  frill  or  ruffle;  it  is  held  in 
place  and  prevented  from  turning  forward  by  a  thin  fold  or  wall  of  membrane,  nearly  an  inch 
in  height,  attached  immediately  beneath  the  middle  of  the  basihyal.  The  external  distri- 
bution of  slime  canals  is  about  as  follows:  Starting  above  the  nostril  in  front  of  the  eye,  a 
line  turns  backward  along  each  side  of  the  skull  and,  after  receiving  a  branch  from  behind 
the  eye,  continues  along  the  middle  of  each  Hank  to  the  extreme  end  of  the  vertebral  column 
in  the  tail,  where  it  makes  an  abrupt  turn  downwards  for  about  a  quarter  of  an  inch:  under 
the  chin  on  each  side  a  line  runs  along  the  mandible  and  curving  upwards  disappears 
behind  the  angle  of  the  mouth:  a  branch  of  this,  beginning  nearly  on  a  vertical  beneath 
the  middle  of  the  space  between  the  eye  and  nostril,  runs  farther  from  the  mouth  and  turn- 
ing upward  near  the  margin  of  the  opercular  flap,  after  receiving  a  short  branch  behind  the 
angle  of  the  mouth,  continues  to  a  point  a  very  short  distance  behind  the  spiracle,  small 
branch  coining  into  it  near  the  end  from  the  direction  of  the  corner  of  the  mouth.  Pectorals 
moderate,  broad,  rounded.  Dorsal  comparatively  small,  its  posterior  extremitj  extending 
as  far  back  as  that  of  the  anal,  angle  blunt.  The  upper  margin  of  the  dorsal  is  armed  with 
a  series  of  enlarged,  compressed,  chisel-shaped  scales,  which  extends  forward  on  the  back 
to  a  vertical  from  the  vent,  a  few  of  the  anterior  being  horizontally  flattened.  Ventrals 
large,  broad,  a  little  broader  than  long,  rounded,  posterior  angle  acute.  Anal  broad,  long. 
rounded,  acute-angled  posteriorly.  Caudal  long,  very  broad,  rounded  anteriorly,  posterior 
angle  acute:  produced  into  a  filamentary  point :  margin  very  thin  or  membranaceous.  Above 
the  muscular  vertebral  portion  of  the  tail  there  is  a  narrow  expanse  of  tin.  widening  back 
ward,  the  edge  of  which  is  armed  by  a  sharp  series  of  chisel  shaped  scales,  and  extended 
downward  behind  the  end  of  the  vertebral  column,  where  it  becomes  about  three  sixteenths 
of  an  inch  in  width.  That  it  is  the  dorsal  portion  of  the  tin  which  descends  is  proved  by  the 
change  in  the  direction  of  the  points  of  the  scales  and  of  the  mucus  canal.  The  dorsal  por- 
tion of  the  tin  is  plainly  indicated  on  the  hinder  margin  of  the  tail  about  half  \va\  down  to 
the  filamentary  point.     The  chisel-shaped  scales  are  in  reality  formed  from  two   series  (one

belonging  to  each  side  of  the  body)  which  have  coalesced.  Though  small  and  harsh  to  the 
touch,  the  scales  on  the  body  are  not  sharp;  they  offer  about  the  same  resistance  from  what- 
ever direction  the  finger  may  be  passed  over  them.  On  the  tail,  however,  they  are  very 
sharp  and  the  points  are  directed  backward.  Along  the  edges  of  the  canals  on  both  body 
and  tail  the  scales  are  compressed  and  flattened;  they  form  the  only  cover  or  protection  for 
these  organs,  which  in  the  specimen  described  have  the  appearance  of  long  seams  or  grooves. 
On  the  skull  these  canals  do  not  stand  open  as  on  the  rest  of  the  body.  Xear  the  mouth, 
and  especially  toward  its  angle,  the  scales  are  larger  and  more  prominent.  Under  the 
middle  of  the  belly,  the  skin  forms  two  closely  approximated  rolls  or  ridges  separated  by  a 
groove,  and  inside  of  these  the  muscle  is  thicker  than  towards  the  thinks.  Intestine  very 
small,  valve  spiral.  Abdominal  pores  opening  behind  the  vent,  protected  by  a  fold.  Car- 
tilages soft  and  flexible  as  those  of  Somniosus  or  Selache.  Uniform  brown,  darker  at  the 
thin  margins  of  the  tins. 

This  species  was  first  described  in  188-4  from  a  specimen  in  the  .Museum  of  Comparative 
Zoology,  believed  to  have  come  from  Japan.  At  this  time  it  was  suggested  that  it  might 
correspond  very  closely  to  an  animal  24  feet  in  length,  observed  in  1880  at  I'emaquid,  Me. 
(Bull.  IT.  S.  Fish  Com.,  m,  p.  407,  cut),  and  that  it  was  one  of  the  forms  which  had  been 
discussed  under  the  name  of  sea  serpent.  Gunther  has  since  had  three  specimens,  the 
largest  4  feet  10  inches  long,  from  Yeddo  Bay.  The  Prince  of  Monaco  found  it  near  Madeira, 
March,  1889. 

Order  RAI^E. 

Selachians  with  pectoral  fins  much  developed,  and  produced  from  the  anterior  margins 
forward,  and  connected  with  the  rostral  cartilages,  thereby  constituting  an  integral  part  of 
the  form,  and  not  abruptly  differentiated  from  the  body,  as  in  the  sharks  and  all  true  fishes; 
the  branchial  openings  are  in  two  converging  rows  of  live  each  on  the  inferior  surface  of 
the  body;  spiracles  are  well  developed  behind  the  eyes.  In  other  respects  the  order  essen 
tially  agrees  with  the  Squali,  and  the  two  form  a  common  superorder  or  subclass,  the 
Plagiostomi.  The  form  varies  considerably  in  the  several  members  of  the  order;  on  the 
one  hand,  the  sawfishes  have  an  outline  much  like  that  of  the.  sharks,  and  with  a  long 
caudal  portion,  and,  on  the  other  hand,  the  eagle  rays  and  certain  stingrays  have  a  disk 
extremely  wide — much  wider  than  long — and  the  caudal  portion  is  reduced  to  a  whip-like 
appendage.  These  two  forms  exemplify  the  extremes  of  the  characteristics  according  to 
which  the  order  is  divided  into  two  suborders,  viz:  (1)  Pachyura  (including  the  Baiidce, 
Ehinobatidw,  Pristidce,  and  Torpedirtidce)  and  (li)  Masticura,  including  the  "eagle  rays" 
(Myliobatidce),  "devil-fishes"  (Cephafopteridee),  and  "stingrays"  (  Trygonidce). — Gill. 

Of  the  several  families  which  compose  this  order,  only  one,  the  L'<iiitl<r,  is  represented 
in  the  depths  of  the  sen. 

Family  RAIID^E. 

Rajidw,  Gun'ther,  Cat.  Fish.  Brit.  Mus.,  vm,  1870,  455. 

Disk  broad,  rhomboid,  rough  or  spinous;  tail  stout,  rather  long,  with  a  longitudinal 
lateral  fold,  usually  with  two  dorsal  fins  and  on  some  species  a  caudal  fin;  pectorals  extend- 
ing to  snout;  ventrals large;  no  serrated  spine  on  the  tail;  oviparous;  egg  cases  leathery, 
with  hollow  tendrils  at  each  of  the  four  angles.

Ruiiihr.  with  pectoral  fins  not  continuous  around  the  snout,  with  ventrals  deeply  notched, 
and  caudal  slightly  developed  or  wanting;  with  tail  quite  distinct  from  the  disk,  and  pro-

vided  with  two-rayed  dorsals;  skin  more  or  less  spinous;  dentition  differing  in  the  two 
sexes;  the  mak'  usually  provided  with  a  differentiated  patch  of  spines  on  each  pectoral. 

The  genus  Rata  is  almost  cosmopolitan,  1ml  most  abundant  in  northern  seas. 

In  this  genus  are  included  the  forms  usually  known  by  the  name  of' Skate.  About  forty 
species  have  been  provisionally  described,  of  which  perhaps  twelve  are  found  in  the  Atlantic 
basin  below  the  100  fathom  line.  The  genus  has  not  yet  been  collected  at  a  depth  greater 
than  oil*  fathoms.  Of  the  seven  species  of  Baia  occurring  on  the  British  coast,  four  at  least 
have  been  found  in  deep  water.  Of  the  nine  species  of  the  Atlantic  coast  of  North  America, 
five  have  been  found  in  the  depths. 

The  Bays  are  believed  to  have  been  abundant  in  the  Cretaceous  and  Tertiary  periods, 
but  the  species  most  characteristic  of  early  geological  times  is  allied  rather  to  the  forms 
now  living  in  shallow  water  than  to  those  of  greater  depths. 

The  Bays  of  the  eastern  and  western  Atlantic  have  not  been  compared  with  a  suffi 
ciently  large  number  of  individuals  at  hand,  and  it  is  probable  that  when  this  shall  be  done 
the  number  of  species  for  the  north  Atlantic  will  be  considerably  reduced. 

The  curious  egg  cases  of  the  Kays,  rectangular,  black,  leathery,  with  tubular  flexible 
tendrils  at  each  of  the  four  angles,  popularly  known  as  "  devil's  knitting  sheaths"  or  "mer- 
maid's purses,"  are  well  known  to  every  stroller  along  the  seashore.  The  large  egg  cases 
of  Baia  Iwvis  are  especially  familiar. 

An  unfamiliar  form  of  egg,  large,  square,  and  with  short  tendrils,  was  found  at  various 
depths  off  Newport  in  1880,  and  young  skates  with  extremely  long  tails  were  taken  from 
them.  These  have  not  yet  been  satisfactorily  identified,  but  it  will  possibly  be  found  that 
they  belong  to  Baia  radiata.

Baia  with  large  spinous  plates  or  bucklers,  in  addition  to  the  spines  on  pectorals,  head, 
back,  ami  tail  found  in  B.  ocellata.  These  are  large,  strong  spines,  with  broad  stellate  or 
shield-like  bases.  They  are  arranged  as  follows:  One  or  two  in  front  of  each  eye;  one  on 
each  side  between  the  eye  and  the  spiracle;  a  pair  on  the  shoulder,  the  smaller  in  front; 
and  fourteen  or  more  forming  a  dorsal  row,  beginning  just  back  of  the  head  and  extending 
to  the  caudal.  An  irregular  row  of  spines  on  each  side  of  the  tail,  separated  from  the 
membrane  by  a  band  of  shagreen;  males  with  two  or  more  rows  of  claw-like  spines  on  the 
pectorals.  Teeth  with  a  long,  sharp  point,  rising  from  the  middle  and  hooking  backwards 
in  the  male,  bluntish  in  the  female;  females  larger  than  the  males  and  more  spinous.

•■  Adult  male  with  the  additional  patches  of  spines  usual  in  this  genus.''     (Giinther.) 
This  species,  the  "  Sandy  Ray  "  of  British  writers,  is  closely  allied  to  Raia  erinacea, 
Mitchill  (  =  Kaia  cijlanteria,  as  defined  by  Giinther),  the  most  abundant  of  all  skates  on  the 
coast  of  New  England,  which  has,  however,  not  yet  been  found  below  the  100  fathom  line. 
Giinther  speaks  as  follows  of  the  abyssal  range  of  I\'.  cireularis: 

"One  specimen,  a  female,  15  inches  long,  was  obtained  on  the  cruise  of  the  Triton,  in 
the  Faroe  Channel,  at  a  depth  of  516  fathoms  (station  111.  August  24,  1882).  Also,  Collett 
reports  its  occurrence  in  130  and  370  fathoms  off  t  lie  coast  of  Norway.  The  Faroe  specimen 
does  not  differ  in  its  armature  from  specimens  obtained  on  the  south  coast  of  England,  only 
the  spines  on  the  upper  side  of  the  snout  and  the  interorbital  space  are  somewhat  more 
developed,  though  in  this  respect  litoral  specimens  show  likewise  some  variation.  With 
regard  to  color,  it  is  notable  that  the  spot  on  each  side  of  the  back  which,  in  littoral  spec- 
imens, is  variegated  with  yellow,  is  much  smaller  in  the  deep  sea  specimen,  and  uniformly 
black,  without  yellow.  The  lower  parts  are  nearly  uniform  blackish  brown,  which  color  laps 
over  to  the  upper  side  of  the  ventral  fins.     Tail  with  irregular  brownish  cross  bands."

The  margins  of  the  snout  form  a  right  or  nearly  right  angle,  its  extremity  being 
rounded;  the  margin  of  the  body  between  the  snout  and  the  extremity  of  the  pectoral  fin 
is  undulated.  Width  of  the  interorbital  space  considerably  exceeding  that  of  the  orbit  and 
spiracle;  eye  rather  small,  about  as  long  as  the  spiracle.  Distance  between  the  nostrils  a 
little  more  than  their  distance  from  the  end  of  the  snout.  Teeth  very  slender,  acutely 
pointed,  widely  set,  with  narrow  base.     Outer  pectoral  angle  nearly  a  right  one. 

Sides  of  the  trunk  nearly  smooth,  but  the  greater  part  of  the  pectorals  and  the,  margin 
of  the  head,  also  the  snout  and  interorbital  space,  are  studded  with  minute  or  very  small 
spines  resting  upon  a  stellate  base.  A  series  of  larger  spines  runs  along  the  median  line  of 
the  back  and  tail,  commencing  immediately  behind  the  occiput.  A  group  of  three  similar 
spines  occupies  each  side  of  the  shoulder;  a  short  series  composed  of  three  or  tour  spines 
along  the  supraorbital  margin  and  above  the  spiracle.  The  spines  along  the  ridges  of  the 
snout  are  also  somewhat  enlarged.  Grayish  brown  above  with  a  trace  of  a  darker  spot  on 
each  side  of  the  body.  Lower  parts  white  with  large  subsymmetrical  brown  patches.  In 
very  young  specimens  the  lower  parts  are  uniform  white. 

"The  only  example  hitherto  met  with  is  the  male  specimen  now  described,  taken  in  hit. 
about  SO0  N.  and  Ion.  0°  E.,  at  sea,  west  of  the  northern  coast  of  Spitzbergen,  the  most 
northerly  locality,  too,  in  which  this  genus  is  yet  known  to  occur."     (Collett,  op.  cit.,  1880.) 

A  large  mah1  specimen,  244  inches  long,  was  obtained  on  the  cruise  of  the  Knight  Errant, 
at  station  0,  on  August  23,  1880,  in  608  fathoms,  together  with  three  small  ones,  of  which 
two  are  males  G4  inches  long,  and  one  a  female  8  inches  long.  A  fourth  very  young  speci- 
men was  caught  at  station  4  in  about  400  fathoms. 

Dr.  Giinther's  remarks  on  the  peculiar  characters  of  this  species  (Challenger  Report,  loc.

Tail  terminating  in  ;i  very  long  finless  filament,  aboul  as  long  as  the  body  and  head. 
The  first  dorsal  fin  dusc  to  and  subeontinuous  with  the  second  «low  dorsal  fin,  the  upper 

margin  of  which  is  even,  not  notched,  except  just  in  front  of  the  caudal  fin,  which  is  also 
low.  Each  clasper  of  the  male  is  divided  into  two  long,  slender  branches,  which  are  rather 
longer  than  the  snout,  and  the  inner  branch  is  again  longitudinally  divided  into  a  simply 
cartilaginous  sty  liform  part  and  another  coated  with  the  spiny  membrane.  Brown,  marbled 
with  lighter;  dorsal  tins  with  a  broad  black  margin.     [Gimther.) 

This  species  has  been  found  along  the  coast  of  Europe  from  Norway  to  Portugal,  and 
also  oft' Soudan  and  at  the  Azores,  but  never  as  yet  in  North  American  waters.  Individ- 
uals have  also  been  taken  at  the  Cape  of  Good  Hope  and  in  the  seas  of  Japan.  The  Knight 
Errant  and  the  Triton,  in  their  exploration  of  the  Faroe  channel,  obtained  young  individ- 
uals with  their  bodies  from  1  A  to  5  inches  in  length.  These  were  from  a  depth  of  505  to 555 
fathoms.  The  Travailleur,  in  L882,  obtained  in  the  Gulf  of  Gascony  some  very  small  indi- 
viduals, the  least  one  only  130  millimeters  in  length,  and  still  carrying  the  yolk  bag.  This, 
according  to  Vaillant.  was  probably  in  the  horny  egg  case  when  it  was  inclosed  by  the 
dredge  net,  and  fragments  of  the  horny  envelope  were  attached  to  it,  which  proved  to  be 
very  similar  to  those  figured  by  M  idler  and  Dumeril  as  the  egg  case  of  Chimmra. 

This  discovery  is  particularly  instructive,  since,  even  so  late  as  1**7,  Dr.  Gunther  has 
expressed  the  opinion  that  the  ova  which  had  been  described  as  Chimaeroid  probably 
belonged  to  Callorhynchus.  Dr.  Gunther  was  of  the  opinion,  in  L889,  that  there  was  no  well- 
authenticated  egg  of  Chimmra  in  any  collection  :  but  the  adult  Callorhynchus  has  never  been 
found  so  far  north  as  the  Gulf  of  Gascony,  and  Vaillant  is  probably  justified  in  his  conclu- 
sion that  the  familiar  form  of  egg  is  that  of  Ghimcera  monstrosa  or  the  closely  allied  Chi- 
nuvra  affinis. 

As  Dr.  Gunther  has  already  said,  these  discoveries  show  that  Chi mmra  is  a  deep-sea 
fish,  and  one  which  propagates  its  species  in  deep  water,  a  circumstance  which  accounts  for 
the  previous  scarcity  of  young  individuals  in  collections.

A  Ghimcera  with  the  snout  acutely  produced,  the  ante-orbital  flexure  of  the  suborbital 
line  extending  little  above  the  level  of  the  inferior  margin  of  the  orbit;  body  more  elongate 
than  in  0.  monstrosa;  second  dorsal  removed  from  the  first  by  interval  equal  to  the  length  of 
the  base  of  the  latter.  Second  dorsal  much  lower  than  in  the  other  species,  and  with  the 
free  border  straight,  without  undulations.  The  dorsal  spine  with  its  anterior  surface  rounded  ; 
the  ventrals  triangular  and  pointed;  the  pectorals  extending  to  the  outer  axil  of  the  ven- 
trals.  Space  between  first  dorsal  and  the  ventral  wide,  the  pectoral  terminating  much  in 
advance  of  the  ventral.  Caudal  fin  very  small,  terminating  in  a  minute  filament.  Cephalic 
appendages  with  five  spines  on  inner  surface.  Posterior  appendages  tripartite,  but  the 
division  of  the  three  portions  takes  place  at  two-thirds  of  the  distance  from  the  base;  the 
cylindrical  portion  is  larger  and  presents  a  form  different  from  that  in  the  others.  Color 
uniformly  plumbeous. 

This  form  is  closely  allied  to  Chimmra  monstrosa.  It  was  first  described  by  Capello 
from  the  coast  of  Portugal,  and  later  by  Gill  from  the  North  American  side  of  the  Atlantic, 
at  depths  varying  from  2(»()  to  1,200  fathoms.  It  is  very  common  in  the  deep  water  on  the 
outer  edges  of  banks  north  of  Georges  Hanks,  and  was  formerly  often  brought  in  by  the 
Gloucester  halibut  schooners.

Snout  with  a  cartilaginous  prominence,  terminating  in  a  cutaneous  Hap.  Two  dorsal 
tins,  the  anterior  with  a  very  long  and  strong  spine.  Extremity  of  the  tail  distinctly  turned 
upwards,  with  a  fin  along  its  lower  edge,  but  without  one  above.  Anal  fin  close  to  the  cau- 
dal, short  and  deep. 

The  typical  species  of  this  genus,  ft  callorhynchvs  (L.)  {  =  <'.  mtarctica  (Lacepede)

Hydrolagux  Colliei,  Gill,  Proc.  Ac.  Nat.  Sc.  Phila.,  1862,  331. 

Tail  simply  tapering,  without  filament.  Three  dorsal  tins,  besides  the  caudal:  the  first, 
with  the  spine,  is  separated  by  a  considerable  interspace  from  the  second;  the  three  other 
tins  low,  subcoutinuous.  Each  clasper  of  the  male  is  divided  into  two  club-shaped  brandies, 
which  are  rather  shorter  than  the  snout;  both  branches  coated  with  the  spiny  membrane, 
and  the  inner  is  not  subdivided.  Brown,  silvery,  upper  parts  with  round  yellow  spots. 
This  form  occurs  only  in  the  North  Pacific.  It  is  abundant  about  Paget  Sound,  and 
in  southeastern  Alaska.  It  swims  at  the  surface,  and  is  abundant  about  the  wharves  at 
Esquimalt,  where  it  is  called  the  "Ratfish." 

There  is  no  evidence  that  it  descends  to  very  considerable  depths. 

HARRIOTTA,  Goode  and  Bean,  n.  g. 

Snout  exceedingly  elongate,  with  a  cartilaginous  midrib,  and  foliaceous  lateral  expan- 
sions of  the  skin  at  its  base.  Two  dorsal  tins,  the  anterior  with  an  immense  triangular 
spine,  finely  serrated,  upou  its  lateral  edges.  Anal  fin  reduced  to  a  cutaneous  fold.  Lon- 
gitudinal axis  of  the  tail  nearly  the  same  as  that  of  the  trunk,  very  elongate,  with  filamen- 
tous tip,  the  fin  below  much  more  extensive  than  that  above.  No  cephalic  organ.  Gill- 
openings  lateral ;  separated  by  a  wide  isthmus.     Claspers  small  and  simple. 

This  genus  is  named  in  honor  of  Thomas  Harriott,  the  most  eminent  philosopher  and 
naturalist  of  his  day  in  England,  who  was  a  member  of  Raleigh's  Roanoke  colony  in  Vir- 
ginia in  1585,  and  who  published  the  first  work  in  English  on  American  natural  history.

HARRIOTTA   RALEIGHANA,  GOODE  and  Bean,  n.  s.     (Figures  37-40.) 

Tail  extended  in  a  very  long  filament,  much  longer  in  the  older  individuals  than  in  the 
young,  in  whieh  no  filament  exists.  The  first  dorsal  fin  separated  from  the  second  by  an 
interval  nearly  equal  to  the  diameter  of  the  eye  in  the  older  individuals,  very  much  greater  in 
the  younger  ones,  in  which  the  cartilaginous  portion  is  exceedingly  narrow  and  high.  The 
second  dorsal  tin  long  and  low,  its  height  about  equal  to  the  diameter  of  the  eye,  its  length 
equal  to  that  of  the  head.  The  spine  preceding  the  first  dorsal  fin  is  very  strong  ;  its  length 
iu  the  older  individuals  equal  to  the  distance  from  its  own  base  to  the  origin  of  the  second 
dorsal;  in  the  young  it  is  proportionately  much  longer  and  stouter,  and  there  is  also  a 
double  row  of  strong  spines  in  advance  of  the  second  dorsal,  and  in  the  notch  bet  ween 
the  second  dorsal  and  its  continuation  upon  the  upper  part  of  the  tail;  and  there  is 
a  similar  group  of  at  least  six  strong  spines  upon  the  top  of  the  head  back  of  the  inter- 
orbital  space,  and  surrounded  by  the  curve  of  the  forward  extension  of  the  lateral  line. 
Traces  of  these  spines  may  l>e  felt  beneath  the  skin  in  older  individuals  of  both  sexes. 
Claspers  in  the  young  male  examined,  small  and  simple,  in  length  scarcely  equal  to  two- 
thirds  of  the  long  diameter  of  the  eye.  Pectoral  tins  immense,  wing-like,  rounded  in  the 
young,  subfalcate  in  the  older  individuals;  inserted  slightly  in  advance  of  the  origin  of  the 
first  dorsal,  and  extending  in  the  older  forms  beyond  the  root  of  the  ventral.  Ventrals  also 
subfalcate;  similar  in  form  and  appearance  to  the  pectoral,  and  extending  to  a  point  at  two- 
thirds  of  the  distance  from  the  origin  to  the  end  of  the  second  dorsal;  in  length  little  less 
than  half  the  snout.  Iu  the  young  the  ventrals  are  placed  somewhat  farther  back  and  reach 
to  a  point  under  the  origin  of  the  third  section  of  the  dorsal  fin.  The  tail  is  prolonged  in 
a  slender  filament,  and  iu  the  older  individuals  the  cutaneous  flap  upon  its  lower  edge  is 
three  or  four  times  as  deep  as  that  above,  and  extends  beyond  it  anteriorly  and  posteriorly. 
In  the  younger  specimens  the  upper  and  lower  flaps  are  about  equal  iu  height,  and  the 
upper  flap  extends  far  in  advance  of  the  insertion  of  the  lower  one.  The  lateral  line  extends 
in  a  straight  line  from  a  point  beneath  the  origin  of  the  first  dorsal  approximately  to  the 
middle  of  the  lower  caudal  lobe,  which  it  follows  along  its  base  for  the  remainder  of  its 
course;  in  advance  of  the  dorsal  fin  it  bends  downward  in  an  elliptical  course,  and  then 
rises  vertically  from  the  occiput  to  join  its  counterpart  from  the  other  side;  bridle-like 
extensions  of  the  same  system  extend  on  the  sides  of  the  head  under  the  eyes,  curving 
upward  in  front  of  the  eye,  then  downward  and  joining  on  the  under  side  of  the  snout  to 
a  branch  running  from  beneath  the  eye  downward  to  the  base  of  the  pectoral  fin  in  the 
young,  or  under  the  throat  to  a  junction  in  the  older  ones,  and  also  forward  from  the  same 
point  under  the  eyes  to  join  on  either  side  the  circle  which  surrounds  the  mouth.  An  elabo- 
rate system  of  mucous  pores  upon  all  sides  of  the  snout ;  on  the  under  surface  of  the  snout 
in  four  longitudinal  series.  In  the  older  individuals  there  is  an  extension  of  the  lateral 
line  system  on  either  side  of  the  midrib  on  the  snout  to  its  tip,  and  there  are  also  sym- 
metrical continuations  of  the  same  upon  the  under  surface  of  the  snout.  Color,  brown; 
caudal  tila inent  pale. 

The  diameter  of  the  eye  is  contained  5i  times  in  the  length  of  the  snout  in  the  older 
specimens,  and  the  distance  between  the  eyes  is  equal  to  their  diameter. 

Of  this  species  we  have  seen  four  specimens,  the  largest,  a  female  (No.  39415,  IT.  S.  N. 
M.),  25  inches  in  length,  from  39°  44'  30"  X.  hit.,  70  30'  45"  W.  Ion.,  in  1,081  fathoms,  taken 
by  the  steamer  Albatross.  Another,  a  male  (No.  38200,  U.  S.  N.  M.),  I9i  inches  in  length, 
was  taken  by  the  Albatross  in  36°  45'  N.  lat.,  74°  28'  30"  W.  Ion.,  at  a  depth  of  781  fathoms. 
A  third,  a  young  individual  (No.  35520,  U.  S.  N.  M.),  4  inches  in  length,  was  obtained  by 
the  Albatross  in  39°  37'  45"  N.  lat.,  71°  18'  45"  W.  Ion.,  in  991  fathoms.  Still  another.  No. 
35G31,  was  taken  at  station  2235,  lat.  39°  12',  Ion.  72°  03'  30",  707  fathoms. 

The  species  is  named  in  honor  of  Sir  Walter  Raleigh,  by  whom  the  first  English  scien- 
tific explorer  was  sent  to  the  New  World.

There  are  two  distinct  groups  in  Alepocephalus,  probably  of  subgeneric  value.  The 
first  group  includes  the  type.  .1.  rostratus,  Eisso.  It  is  characterized  by  a  somewhat  short, 
compressed  body,  large  head,  with  extended  membranaceous  flaps,  and  by  short  dorsal  and 
anal  fins,  similar  in  size  and  shape  and  nearly  opposite  each  other. 

A.  rostratus  has  the  largest  scales,  50  to  55  in  the  lateral  line  (Yaillaut  claims  to  have 
counted  71  on  a  large  individual),  and  has  a  comparatively  large  eye  and  snout. 

A.  Agassizii  has  somewhat  smaller  scales  (about  90  in  the  lateral  line),  a  comparatively 
larger  head  (3  in  total),  and  the  eyes  slightly  larger  (3A  in  head,  10£  in  body). 

A.  productus  has  a  smaller  eye  than  A.  Agassizii,  and  a  longer  snout,  it  being  about 
one-third  of  the  length  of  the  head.  In  A.  rostratus,  however,  the  snout  length  is  one- 
tenth  of  the  total;  in  A. productus  one-twelfth. 

A.  Blanfordii,  Alcock  (Ann.  and  Mag.  Nat.  Hist.,  1S92,  ii,  357),  from  the  Indian  Ocean, 
has  an  immense  eye. 

A.  niger  of  Giinther  is  a  somewhat  slenderer  form,  with  very  small  scales. 

All  of  these  forms  are  dull  in  color  aud  have  the  ventral  fins  weak  and  inconspicuous. 

A.  Bairdii  represents  another  type,  having  a  stout  body,  about  as  high  in  proportion  to 
its  length  as  in  A.  Agassizii,  etc.,  but  with  a  smaller  head  and  less  voluminous  opercular  flaps 
The  eye  is  comparatively  much  smaller  (18  in  total  length),  and  is  nearer  the  upper  profile 
of  the  head.  The  vertical  fins  are  stronger  and  more  muscular,  and  are  heavily  scaled  at 
their  bases.    Lateral  line  nearly  straight.     Mamillaries  slender,  not  expanded  posteriorly. 

A.  bicolor,  Alcock  (Ann.  and  Mag.,  1891,  ii,  133),  is  from  the  Indian  Ocean,  240-76 
fathoms. 

A.  edentulus,  Alcock,  I.  c.  is  from  the  Indian  Oceau,  475  fathoms.

The  height  of  the  body  is  a  little  more  than  one-fifth  of  the  total  length  (without  caudal) ; 
the  length  of  the  head  is  a  little  less  than  one  third.  Diameter  of  the  eye  contained  thrice 
and  one-fourth  in  the  length  of  the  head,  and  longer  than  the  snout.  Scales  much  longer 
than  wide,  with  the  anterior  (radical)  margin  truncated.  Origin  of  the  dorsal  tin  opposite 
to  the  vent.  Pectoral  fin  longer  than  orbit.  Distance  of  ventral  lit t  from  the  head  three- 
fifths  the  length  of  the  latter.    Uniform  deep  black.     (Giinther.)

This  species  occurs  in  the  deeper  waters  of  the  Mediterranean,  and  was  described  by 
Risso  in  1S20.  Until  1874,  when  the  Challenger  began  her  work,  this  was  the  only  repre- 
sentative of  the  family  known  to  ichthyology. 

The  French  expedition  obtained  twenty-four  specimens  from  off  the  coasts  of  Soudan 
and  Morocco,  from  about  830  to  2,190  meters,  from  the  Banc  d'Arguin;  from  the  Canaries, 
975  meters;  the  Azores,  2,235  meters,  and  the  Cape  Yerde  Islands,  3,655  meters.  Giinther 
is  disposed  to  believe  that  Esunculus  Costal  is  the  young  of  this  species.

An  Alepoeephalus  resembling  A.  Agassizii  in  form  and  proportions,  but  with  larger 
scales,  smaller  eye,  and  longer  snout. 

The  body  isquite  robust,  itsheighl  at  the  pectoral  origin  nearly  one-fourth  of  the  length 
from  the  snout  to  the  base  of  rhe  median  caudal  rays.  Least  heighl  of  the  tail  about  one 
half  the  body  in  length.     The  head  forms  more  than  one  third  (35.5)  ofthe  total  length. 

The  snout   equals  one-third  of  the  length  of  the  head,  the  eye  nearly  s-fourth,  and  the 

posterior  margin  ofthe  orbit  is  nearly  equidistant    between   the  snout   and  the  opercular

margin.  The  upper  jaw  extends  a  little  behind  the  vertical  from  the  posterior  margin  of 
the  pupil;  the  lower  jaw  is  shorter  and  included  by  the  upper,  and  is  nearly  one  half  as  long 
as  the  head.  The  width  of  the  cranium  between  the  orbits  is  one-seventh  of  the  length  of 
the  head,  and  behind  the  orbits,  more  than  one-third.  The  insertion  of  the  dorsal  is  above 
the  vent;  the  length  of  its  base  is  twice  the  diameter  of  the  eye.  The  anal  base  is  under 
the  anterior  portion  of  the  dorsal,  and  the  length  of  its  base  is  about  three  fourths  that  of 
the  dorsal.  The  caudal  flu  has  its  median  rays  as  long  as  the  diameter  of  the  eye,  and  the 
external  rays  at  least  one-fifth  of  the  total  length  of  the  fish.  The  pectoral  commences  at 
a  distance  from  the  snout  equal  to  one-fourth  of  the  length  of  the  body.  The  rentrals  are 
inserted  considerably  behind  the  middle  of  the  length  (0.57),  and  appear  to  have  been  at 
least  as  long  as  the  diameter  of  the  orbit.

Body  comparatively  elongate,  somewhat  compressed,  its  greatest  height,  at  a  point  mid- 
way between  pectoral  and  ventral  insertions,  contained  5J  times  in  its  length  to  the  origin 
of  the  middle  caudal  rays,  its  greatest  width  equal  to  one  tenth  of  total  length,  the  least 
height  of  tail  contained  11  times  in  length  of  body. 

Scales  large,  thin,  oblong,  triangular  at  the  free  end,  those  at  the  base  of  the  anal  fin 
having  the  free  end  more  produced  than  the  others.  Sixty  live  scales  in  the  lateral  line, 
seven  rows  between  it  and  the  origin  of  the  dorsal,  eleven  between  that  of  the  anal  and  the 
lateral  line.     Scales  extend  for  a  short  distance  upon  the  bases  of  the  dorsal  and  anal  tins. 

Head  moderately  compressed,  snout  subcorneal,  the  lower  jaw  included.  The  length  of 
the  head  is  contained  4^  times  in  length  of  body,  slightly  exceeding  twice  the  length  of 
the  lower  jaw.  Width  of  the  head  equal  to  the  length  of  the  operculum  and  very  slightly 
less  than  that  of  the  upper  jaw.  Width  of  interorbital  area  half  of  the  least  height  of  tail. 
Length  of  snout  half  that  of  the  mandible,  which  is  one-ninth  of  the  total  length.  Diam-

Dorsal  inserted  directly  above  the  vent,  slightly  in  advance  of  the  anal  and  at  a  dis- 
tance from  the  snout  nearly  equal  to  two-thirds  of  the  total  length  of  the  body. 

Length  of  longest  ray  of  dorsal  one-half  that  of  the  postorbital  portion  of  the  head. 
The  distance  of  the  anal  from  the  snout  is  almost  3  times  the  length  of  the  head,  its 
first  ray  being  about  under  the  fourth  ray  of  the  dorsal.  Its  length  of  base  is  greater  than 
that  of  the  dorsal  by  one  fifth  of  the  length  of  the  latter;  its  longest  ray  slightly  exceeds 
the  longest  of  the  dorsal. 

Middle  caudal  rays  equal  in  length  to  longest  ray  of  anal,  the  external  rays  somewhat 
more  than  twice  as  long. 

Distance  of  pectoral  from  snout  3  times  as  great  as  the  least  height  of  the  tail;  its 
length  one-tenth  of  total  length  and  equal  to  width  of  body,  reaching  to  ninth  row  of  scales. 

Distance  of  ventral  from  snout  equal  to  twice  the  length  of  the  head,  its  length  slightly 
greater  than  that  of  middle  caudal  rays.

Fishes,  664. 

Body  rather  elongate,  compressed,  covered  with  scales  of  moderate  size.  Cleft  of  the 
mouth  rather  wide,  the  maxillary  extending  to  below  the  middle  of  the  eye.  Botli  in- 
termaxillary and  maxillary  armed  with  a  series  of  minute  teeth,  as  is  also  the  mandible; 
palatine  bones  with  similar  teeth;  those  on  the  latter  often  weak  and  deciduous.  Vomer- 
ine teeth  present  or  absent.  No  teeth  on  the  tongue.  Eye  very  large.  Dorsal  and  anal 
fins  moderately  long,  the  former  behind  the  ventrals.  Adipose  flu  none.  Caudal  forked. 
Gills  very  narrow;  pseudobranchiae  present:  gill  rakers  long,  lanceolate.  Pyloric  append- 
ages in  moderate  number.     Ova  rather  small. 

Bathytroctes  is  closely  allied  to  Alepocephalus,  from  which  it  differs  chiefly  in  the  pres- 
ence of  teeth  on  the  maxillary.  Ten  species  have  been  described,  seven  of  which  are  from  the 
Atlantic.  One  of  these,  B.  attritus,  is,  by  the  admission  of  its  describer,  quite  as  likely  to 
belong  to  some  other  genus — perhaps  Alepocephalus. 

The  type  of  this  genus  is  Bathytroctes  macrolepis,  Gunther,  from  a  depth  of  2,150  fath- 
oms, north  of  Celebes  [Challenger  station  xcvm). — 1'>.  squamosus,  Alcock  is  from  740  fathoms 
in  the  Arabian  Sea.     B.  stomias,  Gilbert,  is  from  877  fathoms,  off  Oregon  and  Washington.

A  Baihytroctes  with  the  dorsal  tin  tar  in  advance  of  the  anal,  and  the  maxillary  reach- 
ing to  below  the  posterior  third  of  the  orbit.  Larue  scales  and  short  vertical  tins,  'flic 
height  of  the  body  is  two-elevenths  of  its  length;  the  head  slightly  more  than  one-third. 
Head  depressed,  elongate,  scaleless;  broad  across  the  occipital  region,  tapering  forward;  its 
upper  surface  deeply  concave  longitudinally.  Eye  large;  its  diameter  greater  than  the 
length  of  the  snout  and  3^  in  length  of  head.  Interorbital  space  halt  the  diameter  of  the 
eye.  Suout  pointed,  daws  equal.  Cleft  of  mouth  rather  wide;  the  maxillary  extending 
beyond  the  vertical  from  the  center  of  the  eye.  Dentition  weak;  teeth  small, equal, pointed, 
uniserial:  intermaxillary  and  front  of  maxillary  toothless;  vomerine  teeth  in  two  groups; 
palatine  teeth  few,  about  9. 

Vent  about  midway  between  the  branchial  opening  and  the  caudal.  The  dorsal  inser-

The  maxillary  reaches  to  below  the  hind  margin  of  the  orbit;  intermaxillary  terminat 
ing  in  front  in  a  short  projection. 

The  height  of  the  body  is  nearly  one-fifth  of  the  total  length  (without  caudal);  the 
length  of  the  head  one-third.  Hones  of  the  head  very  thin  and  very  easily  ruptured,  like 
all  the  other  parts  of  the  body.  Head  compressed,  moderately  deep,  its  depth  at  the  occi- 
put being  three  fifths  of  its  length;  its  upper  surface  longitudinally  concave,  the  width  of 
the  interorbital  space  being  more  than  one-half  of  the  longitudinal  diameter  of  the  eye. 
Lye  large,  a  little  longer  than  deep,  contained  thrice  and  two-thirds  in  the  length  of  the 
head  and  equal  to  that  of  the  snout.  Infraorbital  ring  narrow,  the  broad  and  large  maxil- 
lary being  separated  from  the  orbit  by  a  narrow  strip  of  bone.  Snout  wedge-shaped,  with 
a  pair  of  short  and  flat  projections  in  front,  each  being  formed  by  the  intermaxillary  and 
toothed  at  its  extremity.  The  (deft  of  the  mouth  is  wide,  the  maxillary  extending  to  below 
the  hind  margin  of  the  orbit.  Dentition  very  feeble,  all  the  teeth  being  minute  and  uni- 
serial.  The  intermaxillary  and  maxillary  are  toothed  throughout  their  whole  extent:  the 
teeth  of  the  mandible  are  particularly  minute,  and  the  series  is  interrupted  close  to  the 
symphysis,  the  syniphyseal  portion  being  external  to  the  lateral  portion,  which  is  implanted

on  the  upper  edge  of  the  bone.  The  vomerine  teeth  are  reduced  to  a  pair  of  very  small 
teeth  in  the  middle  of  the  bone.  Palatine  teeth  none,  or  reduced  to  a  single  tooth-like  pro- 
jection. 

Branchiostegals  long,  narrow,  slender.  Gills  as  in  Bathytroctes  macrokpis.  Gill  rakers 
long,  lanceolate,  closely  set,  20+7  on  the  outer  branchial  arch. 

Vent  nearer  to  the  gill  opening  than  to  the  root  of  the  caudal.  Origin  of  the  dorsal 
fin  somewhat  in  advance  of  the  vent;  it  is  much  longer  than  high,  the  length  of  the  ante- 
rior rays  increasing  to  the  sixth  or  seventh  ray.  Origin  of  the  anal  fin  below  the  anterior 
half  of  the  dorsal,  which  it  resembles  in  shape.  Caudal  fin  deeply  emarginate.  Pectoral 
inserted  a  short  way  above  the  lower  profile,  rather  short  and  broad,  about  as  long  as  the 
eye.  Ventrals  broad,  extending  to  the  vent,  their  root  being  rather  nearer  to  the  base  of 
the  caudal  than  to  the  extremity  of  the  snout. 

Scales  simple,  cycloid,  in  about  1-'  longitudinal  series  above  and  below  the  lateral  line, 
between  the  dorsal  and  ventral  fins.  Lateral  line  straight,  running  from  the  upper  end 
of  the  gill  opening  along  the  middle  ot  the  tail,  with  rather  small  mucous  apertures. 

Color,  uniform  black.

The  maxillary  extends  to  below  the  posterior  third  of  the  orbit.  Height  of  the  body 
r»i  in  total  length  (without  caudal),  the  head  3f.  Bones  of  head  thin  (as  in  Bathytroctes 
macrolejyis).  Head  rather  compressed,  moderately  deep,  its  depth  at  the  occiput  being  two- 
thirds  of  its  length;  its  upper  surface  is  concave,  the  width  of  the  interorbital  space  being 
one-half  of  the  longitudinal  diameter  of  the  eye.  Eye  very  large,  rather  longer  than  deep, 
one-third  of  the  length  of  the  head,  and  considerably  longer  than  snout.  Infraorbital  ring 
rather  narrow,  the  broad  maxillary  separated  from  the  orbit  by  a  very  narrow  strip  of  bone. 
Snout  somewhat  wedge-shaped,  with  upper  profile  declivous,  with  jaws  equal  in  front  and 
with  maxillary  extending  to  posterior  third  of  the  orbit.  Dentition  feeble;  all  the  teeth 
equally  minute  and  uniserial;  intermaxillary  and  maxillary  toothed  throughout;  vomerine 
series  transverse  and  straight,  slightly  interrupted  in  middle;  palatini  series  nearly  as  long 
as  vomerine.  Branchiostegals  slender,  rod-shaped.  Gills  four,  that  of  fourth  arch  being 
short  and  reduced  to  a  horizontal  series  of  lamina',  which  is  only  one-third  of  the  horizon- 
tal series  of  the  outer  branchial  arch.  Gill  laminae  very  short,  especially  on  the  convex 
portion  of  the  arches;  gill  rakers  long,  lanceolate,  closely  set,  24+11  on  the  outer  branchial 
arch. 

Vent  considerably  nearer  to  root  of  caudal  fin  than  to  gill  opening,  whilst  origin  of 
the  dorsal  fin  is  somewhat  nearer  to  latter.  Dorsal  fin  longer  than  high,  its  anterior  rays 
increasing  in  length  to  fifth  or  sixth  ray.  Origin  of  anal  behind  vertical  from  middle  of 
dorsal  fin.  Caudal  tin  deeply  emarginate.  Pectoral  inserted  a  short  way  above  lower 
profile;  it  has  a  moderately  broad  base,  is  three-fifths  of  the  length  of  the  head,  and  does 
not  extend  to  ventral.  Ventrals  close  together,  scarcely  extending  to  vent,  their  root  being 
midway  between  root  of  caudal  and  anterior  margin  of  orbit. 

Scales  deciduous,  cycloid,  with  numerous  fine  concentric  and  radiating  stria-;  there 
were  probably  9  scales  in  a  transverse  series  between  the  lateral  line  and  the  origin  of  the 
dorsal  fin  and  between  the  lateral  line  and  the  ventral  fin.  Lateral  line  straight,  running 
from  the  upper  end  of  the  gill  opening  along  the  middle  of  the  tail,  with  rather  narrow 
mucous  apertures.    Color,  uniform  black.     (Giinther.)

BATHTTEOCTES  MELANOCEPHALUS,   V.mi.iam. 
Bathytroctea  melanocepholus,  Yaillaxt,  Ex]i.  Sci.  Travailleni  el  Talisman,  1888,  155,  pi.  xi.  Bgs.  3a,  3b. 

Height  of  body  one-fifth  of  total  length,  its  greatesl  thickness  one-eighth.  The  length 
of  the  head  is  two-fifths  of  the  total  length;  the  anterior  profile  is  somewhat  oblique.  The 
length  of  the  snout  is  equal  to  one  third  of  the  distance  from  its  tip  to  the  posterior  edge  of 
the  operculum.  The  maxillary  extends  to  a  vertical  slightly  behind  the  posterior  margin  of 
the  orbit.  The  intermaxillary  teeth  and  those  on  the  mandible  are  elongate,  line,  conical, 
nniserial,  separated  from  each  other  by  spaces  scarcely  equal  to  their  own  thickness.  The 
e\  e  is  very  large;  its  diameter  two  elevenths  of  the  length  of  the  head  ;  interorbital  Space 
slightly  less.  In  fresh  condition  the  framework  on  the  operculum,  which  is  very  delicate, 
is  hidden  in  the  soft  integument,  forming  a  curtain,  far  extended  posteriorly.  After  having 
been  in  alcohol,  a  great  number  of  radiating  ribs,  extending  downward  ami  backward  on 
the  operculum,  are  seen.  Vent  considerably  in  advance  of  the  anal,  ami  near  the  middle  of 
the  distance  from  the  posterior  edge  of  the  operculum  to  the  base  of  the  caudal.  Lateral 
line  is  in  the  median  line  of  the  body,  except  in  its  anterior  part :  the  scales  which  compose 

it  are  more  conspicuous  than  on  the  rest  of  the  body — twice  as  large,  that  is  to  say <• 

of  them  corresponds  ordinarily  to  two  transverse  rows — and  there  are  about  64  of  them  in 
the  total  length  of  the  lateral  line.  The  dorsal  is  inserted  above  the  interspace  between  the 
ventrals  and  the  origin  of  the  anal,  the  anal  being  shorter  than  the  dorsal.  Both  anal  and 
dorsal  are  low.     Caudal  einarginate.     Pectoral  and  ventral  short,  the  former  with  13  rays. 

The  body  is  grayish  green;  head  deep,  blackish  blue;  fins  brown;  eye  with  gray  blue 
iris  and  black  pupil.  Scales  oval,  those  of  the  lateral  line  peculiar  in  form  (fully  described 
and  figured  by  Yaillant). 

Pour  specimens  were  obtained  by  the  Travailleur  in  the  middle  eastern  Atlantic;  two 
from  the  coast  of  Morocco,  from  2,200  to  2,500  meters;  one  from  the  coast  of  Soudan,  1,435 
meters;  one  from  the  Banc  D'Arguin,  1,(>70  meters.     The  type  is  108  millimeters  in  length. 

It  would  appear  from  the  published  descriptions  that  B.  melanocepholus  is  well  distin- 
guished from  II.  microlepis,  although  both  have  been  taken  in  the  same  region.  The  most 
salient  diagnostic  characters,  as  published,  are  included  in  the  analytical  key  to  the  species 
on  a  preceding  page.

Body  elongate;  its  height  one-seventh  of  its  total  length:  thickness  one-thirteenth. 

The  length  of  the  head  is  about  one  third  of  the  total  length,  and  the  snout  one-third 
of  the  length  of  the  head.  The  maxillary  extends  nearly  to  the  vertical  from  the  middle  of 
the  eye.  and.  like  the  intermaxillary,  it  is  armed  with  conical  teeth,  not  very  closely  set. 
Teeth  on  the  mandible  lancet-shaped,  curved  inward.  Opercular  apparatus  membranous. 
Vent  twice  as  far  from  the  snout  as  from  the  root  of  the  caudal.  The  dorsal  and  anal  fins 
are  nearly  opposite  and  approximately  equal  in  length  (the  type  specimen  was  much  muti- 
lated, and  an  exact  description  has  not  been  given):  the  origin  of  the  dorsal  is  above  the 
vent,  and  the  length  of  its  base  is  slightly  greater  than  the  greatest  height  of  the  body; 
the  anal  resembles  it  very  closely  and  extends  very  slightly  beyond  it  posteriorly.  The 
pectoral  fin  appears  to  have  been  somewhat  elongate,  pointed,  with  its  tip  extending  beyond 
the  base  of  the  ventral,  which  is  situated  almost  in  the  middle  of  the  length  of  the  body. 
Scales  moderate,  6  above  and  14  below  the  lateral  line.

44  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

A  single  specimen  was  obtained  by  the  French  expedition  at  Station  lxxxvii,  from  the 
Banc  d'Arguin,  at  a  depth  of  1,113  meters.  The  type  appears  to  have  been  very  badly 
mutilated,  but  M.  Vaillant  has  made  a  careful  restoration  in  the  figure  which  he  presents. 

This  species,  like  B.  antillarum  and  B.  australis,  belongs  to  a  division  of  the  genus 
distinguished  by  having  the  dorsal  and  anal,  equal  in  length,  and  nearly  opposite.  For  this 
group  a  subgenus  is  proposed  under  the  name  of  Talismania. 

BATHYTROCTES  (TALISMANIA)  ANTILLARUM,  Goode  and  Bean,  n.  s.     (Figure .49.) 

The  maxillary  extends  below  tlie  anterior  portion  of  the  orbit,  and  essentially  to  the 
vertical  from  the  anterior  margin  of  the  pupil.  The  height  of  the  body  is  contained  5  times 
in  the  total  length  (without  caudal);  the  head  3£.  Bones  of  the  head  thin;  head  coin- 
pressed,  moderately  deep,  its  depth  at  the  occiput  being  three-fifths  of  its  length.  The 
profile  of  the  head  in  advance  of  the  orbit  is  slightly  concave,  the  upper  margin  of  the  orbit 
approaching  very  close  to  the  upper  inutile;  the  supraorbital  rim  forming  a  portion  of  the 
dorsal  profile  of  the  head.  The  width  of  the  interorbital  space  is  nearly  half  the  diameter 
of  the  eye.  Eye  large,  conspicuous,  its  diameter  equal  to  one  third  of  the  length  of  the 
head;  the  pupil  also  large,  its  diameter  two  fifths  that  of  the  orbit;  its  horizontal  diameter 
considerably  greater  than  the  length  of  the  snout,  its  vertical  diameter  equal  to  the  length 
of  the  snout,  which  is  contained  4  times  in  the  length  of  the  head.  Interorbital  ring  very 
narrow  :  the  maxillary  is  separated  from  the  orbit  by  a  very  narrow  strip  of  bone.  Snout 
sharply  conical,  its  upper  profile  concave,  jaws  equal  in  front.  Dentition  feeble;  all  the 
teeth  equal,  minute,  uniserial.  intermaxillary  and  maxillary  toothed  throughout.  Vomer- 
ine series  transverse  and  straight,  slightly  interrupted  in  the  middle;  palatine  series  nearly 
as  long  as" the  vomerine;  the  two  last-named  series  confluent.  Branchiostegals  7 ;  exceed- 
ingly slender  and  long,  Gills  4;  the  fourth  well  developed,  with  a  slit  behind  it.  Gill 
laminae  short,  especially  on  the  convex  portion  of  the  arches.  Gill  rakers  long,  lanceolate, 
closely  set;  17  on  the  outer  branchial  arch  below  the  angle;  7  above.  Vent  equidistant 
between  the  root  of  the  caudal  and  the  gill  opening;  origin  of  the  dorsal  Dearer  to  the  latter. 
Dorsal  fin  longer  than  high,  its  anterior  rays  increasing  in  length  from  the  eighth  to  the 
nineteenth  ray.  Origin  of  the  anal  somewhat  in  advance  of  the  dorsal,  which  is  inserted 
over  the  third  ray  at  the  point  where  it  emerges  from  its  scaly  sheath.  Caudal  tin  deeply 
emarginate.  Pectoral  fin  inserted  in  the  lower  third  of  the  height  of  the  body;  moderately 
broad  at  its  base;  its  upper  rays  nearly  twice  as  long  as  the  lower  ones;  its  length  half  that 
of  the  head,  and  its  tip,  when  extended  straight,  in  the  vertical  from  the  insertion  of  the 
ventral,  which  passes  through  the  twelfth  scale  of  the  lateral  line.  Ventrals  close  together, 
not  reaching  to  the  vent,  but  to  the  origin  of  the  sheath  which  incloses  both  the  vent  and 
the  base  of  the  anal  fin  :  its  length  equal  to  that  of  the  lower  rays  of  the  pectoral  and 
to  that  of  the  snout.  The  root  of  the  ventral  midway  between  the  tip  of  the  snout  and 
the  root  of  the  anterior  caudal  rays.  Scales  large,  deciduous,  cycloid  ;  about  9  horizontal 
rows  above  the  ventrals.  Lateral  line  curving  in  a  concave  sweep  from  near  the  upper 
angle  of  the  operculum  to  a  point  above  the  origin  of  the  basal  sheath  of  the  anal,  thence 
in  a  straight  line  to  the  base  of  the  caudal.  Color  of  the  specimen  (denuded  of  scales  and 
long  kept  in  alcohol),  a  rusty  brown;  head  blackish.

BATHYTROCTES  (TALISMANIA)  ^EQUATORIS,  Goode  and  Beax,  n.  s.     (Figure  50.) 

A  species  of  Bathytroctes  resembling  B.  antillarum  in  the  size  of  the  scales,  bui  with  a 
mouth  larger  than  that  in  B.  homopterus. 

The  maxillary  reaches  to  the  vertical  from  the  posterior  margin  of  the  orbit.  The  height 
of  the  body  is  contained  5§  times  in  the  total  length;  the  length  of  the  head  3£.  Bones  of 
the  head  thin;  head  large,  compressed,  the  depth  at  the  occiput  being  three-fourths  its 
length,  its  width  about  one-third.     Its  upper  surface  longitudinal,  concave,  and  deeply  con-

cave  between  the  orbits,  with  a  convexity  above  the  snout.  Width  of  the  [nterorbital  space 
about  equal  to  the  diameter  of  the  eye.  The  length  of  the  snout  contained  3jj  times  in  thai 
of  the  bead.  Eye  large,  a  little  longer  than  deep,  contained  l'r;  times  in  the  length  of  the 
head  and  L\  times  in  the  length  of  the  snout.  Infraorbital  ring  very  narrow.  The  maxil- 
lary is  broad,  large,  and  conspicuously  dilated  at  the  extremity,  its  greatest  width  at  this 
point  being  more  than  two  thirds  the  diameter  of  the  eye.  Cleft  of  the  mouth  wide.  Den- 
tition feeble:  no  traces  of  teeth  upon  either  vomer  or  palatine.1  Branchiostegals  5,  long 
and  slender.  Gills  4.  Gill  laminae  short,  especially  on  the  convex  portion  of  the  arches. 
Gill  rakers  long,  strong,  broad  at  the  base;  (J+  17  on  the  outer  arch. 

Vent  placed  equidistant  from  root  of  caudal  and  root  of  pectoral.  The  origin  of  the  dorsal

anterior  rays  increasing  in  length  to  tlie  middle  of  the  tin.  the  longest  ray  contained  3§  in 
length  of  head,  and  about  equal  to  the  longest  ray  of  the  anal.  Caudal  tin  deeply  emargi- 
natc.  Pectoral  inserted  far  below  the  middle  of  the  body.  It  has  a  narrow  base,  and  its 
length  in  a  perfect  specimen  is  probably  not  greater  than  the  diameter  of  the  eye.  Yentrals 
close  together,  remote  from  the  vent,  the  root  being  nearly  midway  between  the  root  of  the 
caudal  and  the  tip  of  the  snout,  and  equidistant  from  the  root  of  the  anal  and  the  base  of 
the  pectoral. 

Scales  deciduous,  cycloid,  45  or  48  in  the  lateral  line,  the  lateral  line  beginning  from  a 
point  on  a  level  with  the  top  of  the  eye,  and  ascending  in  a  broad  curve  to  a  point  over  the 
ventrals,  and  thence  in  a  straight  line  to  the  root  of  the  caudal.     Color,  bluish  black.

BATHYTROCTES  ATTRITUS,  Vaillant. 

Bathytroctes  attritus,  Vaillant,  Exp.  Sci.  Travailleur  et  Talisman,  Poissons,  1888,  158,  pi.  XII,  fig.  2  (struc- 
tural details). 

This  name  was  given  by  Vaillant  to  certain  mutilated  fishes  obtained  from  the  Azores, 
Cape  Verde,  and  Banc  d'Arguin,  at  1,550  to  3,655  metres  If  they  belong  to  Bathytroctes  at 
all,  they  appear  to  resemble  most  closely  B.  melanocephalus.  Until  fresh  material  shall  be 
obtained,  it  seems  doubtful  whether  B.  attritus  is  a  valid  species. 

NARCETES,  Alcock. 

Narcetes,  Alcock.  Ann.  aid  Mag.  Nat.  Hist.,  1890,  n,  305,  vn,  1891,  i,  10. 

Body,  as  in  Bathytroctes,  rather  elongate,  compressed,  covered  with  scales  of  moderate 
size.  Eye  rather  small.  Cleft  of  mouth  wide,  the  maxillary  extending  beyond  the  vertical 
through  the  middle  of  the  eye.  Teeth  in  premaxillary  and  mandible  fine, pluriseria I;  line 
teeth  on  maxillary,  palatines  and  vomer;  no  teeth  on  tongue.  Dorsal  and  anal  fins  rather 
short,  the.  former  beginning  in  vertical  from  origin  of  ventral.  No  adipose  dorsal.  Caudal 
symmetrically  forked,  dill  openings  wide.  Pseudobranehia?  present.  Gill  rakers  com- 
plete; 7  branchiostegals;  4  gills,  with  narrow  lamina?.  Gill  rakers  long.  Pyloric  append- 
ages in  moderate  number. 

The  type  of  this  genus  is  Narcetes  eremilas,  Alcock  (1.  c),  obtained  by  the  Investigator 
in  the  Arabian  Sea  (station  105)  at  a  depth  of  740  fathoms.  The  description  is  based  upon 
two  female  specimens,  measuring  13A  and  94  inches  respectively.

I'latytroetes,  Gunthkr,  Ann.  and  Mag.  Nat.  Hist.,  1878,  II,  249;  Challenger  Report,  XXII,  229. 

Body  rather  abbreviated,  much  compressed,  and  covered  with  small  keeled  scales. 
Mouth  of  moderate  width;  the  maxillary  and  intermaxillary  and  mandible  armed  with  a 
single  series  oi  small  teeth.     Palate  smooth.     Eye  rather  large.     The  dorsal  and  anal  fins

i. vm,  fig.  A. — Alcock,  Ann.  and  Mag.  Nat.  Hist.,  vi,  1890,  n.  307. 

Body  much  compressed  and  deep;  its  greatest  depth  at  about  the  middle  of  its  length, 
and  contained  in  it  2f  times,  not  including  the  caudal.  Head  compressed,  moderate,  two- 
sevenths  of  the  length  of  the  body,  longitudinally  concave  above,  the  concavity  bordered  on 
each  side  by  a  perforated  muciferous  canal,  and  broadest  behind,  tapering  to  a  pointbetween 
the  nostrils.  Bones  of  head  are  rather  thin,  but  less  so  than  in  Bathytroctes.  Bye  large, 
one-third  of  the  length  of  the  head,  equal  to  snout,  and  situated  close  to  upper  profile. 
Infraorbital  ring  incomplete.  Mouth  rather  small,  the  lower  jaw  projecting.  Maxillary 
broad,  short,  extending  to  vertical  from  margin  of  orbit.  Dentition  very  feeble ;  teeth  uni- 
serial,  uniformly  minute,  occupying  the  whole  extent  of  intermaxillary  and  the  maxillary, 
but  confined  to  the  front  part  of  the  mandible;  only  a  few  rudimentary  teeth  are  visible  on 
the  side  of  the  mandible.     Vomer  with  a  minute  tooth  on  each  side;  palatines  toothless. 

Branchiostegals  extremely  slender,  curved.  Gills  four;  the  inner  one  very  short;  gill 
lamime  short,  especially  on  the  convex  portion  of  the  arches;  gill  rakers  long,  lanceolate, 
•  closely  set,  20  +  10  on  the  outer  branchial  arch. 

Vent  is  much  nearer  to  root  of  caudal  than  to  gill  opening.  Dorsal  tin  commences 
immediately  above  it,  the  anal  behind;  these  fins  are  very  similar  in  shape  and  of  moderate 
height.  Caudal  peduncle  more  than  half  as  deep  as  long,  its  depth  being  increased  by  a 
fold  of  the  integument  between  the  vertical  fins.  Caudal  rather  short  and  forked.  Pecto- 
ral very  short,  only  half  as  long  as  the  eye. 

Scales  small,  cycloid,  each  with  a  longitudinal  keel,  and  not  spinigerous,  as  in  Maerunu, 
but  simple,  as  in  the  keeled  scales  of  a  snake;  the  striatums,  instead  of  continually  crossing 
the  scale,  are  interrupted  by  the  raised  median  line.  Head  entirely  scaleless.  Lateral  line 
straight,  running  along  the  middle  of  the  body  and  tail,  and  composed  of  very  small  pores. 

Brown;  head,  pectoral  region,  the  vent,  and  fringes  of  the  caudal  peduncle  black. 

Radial  formula:  D.  18;  A.  17;  P.  20;  L.  lat.  about  100. 

A  single  individual,  ~>i  inches  long,  was  taken  by  the  Challenger  at  station  107,  in  the 
middle  Atlantic,  at  depth  of  1,500  fathoms.  Alcock  records  it  from  the  Arabian  sea,  Investi-

Xenodermichihys,  Gunther,  Ann.  and  Mag.  Nat.  Hist.,  n,  1878,  250;  Challenger  Report,  xxn,  1887,  230. 
Body  rather  elongate,  compressed,  withotit  true  scales.  The  skin  is  rather  tough,  finely 
wrinkled  longitudinally,  with  numerous  small  nodules,  regularly  arranged,  which  possess 
the  structure  and  probably  the  functions  of  luminous  organs.  Minute,  rudimentary,  scale- 
like productions  are  imbedded  in  the  skin,  especially  on  the  trunk.  Month  very  small,  with 
feeble  jaws  and  rudimentary  teeth  in  the  intermaxillary  and  mandible,  and  a  few  in  the 
maxillary.  Palate  toothless.  Dorsal  and  anal  fins  equal  in  length.  Caudal  forked.  Gill 
opening  wide,  but  not  extending  much  above  the  level  of  the  pectoral  fins.  Gills  well 
developed;  pseudobranchise.     Gill  rakers  long.

small,  with  minute  teeth  on  intermaxillary  and  anterior  portion  of  mandible.  Maxillary 
short,  broad,  very  thin,  reaching  slightly  beyond  the  vertical  from  the  anterior  margin  of 
the  orbit.  Eye  moderate,  not  entering  into  the  upper  profile;  its  diameter  greater  than  the 
width  of  the  interorbital  space,  and  two-ninths  the  length  of  the  head.  Snout  shorter  than 
the  diameter  of  the  orbit.  Vent  midway  between  the  root  of  the  caudal  and  the  pectoral. 
Dorsal  and  anal  similar  in  form  and  equal  in  extent,  the  anal  beginning  slightly  behind  the 
vent,  and  the  dorsal  immediately  above  it.  The  bases  of  the  posterior  rays  of  the  two  fins 
opposite.  The  ultimate  rays  of  these  tins  are  the  longest,  the  length  of  the  rays  gradually 
increasing  from  beginning  to  end.  Caudal  peduncle  nearly  twice  as  long  as  its  own  height. 
Caudal  deeply  forked,  with  filamentous  lobes,  preceded  above  and  below  by  numerous  rudi- 
mentary lays.  Pectoral  placed  low,  narrow,  pointed :  its  length  three-fifths  that  of  the  head. 
Ventrals  narrow,  reaching  to  vent;  their  length  equal  to  half  that  of  the  head. 

Skin  tough,  leathery,  finely  wrinkled,  studded  with  small  raised  nodules,  which  extend 
upon  the  rays  of  all  the  fins  except  the  caudal;  much  more  numerous  below  than  above  the 
lateral  line,  which  is  very  conspicuous,  broad,  straight,  originating  close  behind  the  eye  and 
extending  along  the  middle  of  the  body  and  tail  to  the  base  of  the  caudal  rays. 

Radial  formula:  D.  33;  A.  33;  P.  6;  V.  5. 

A  single  specimen,  8  inches  in  length,  was  taken  by  the  Challenger  at  station  ccxxxn,

ALEPOSOMUS,  Gill. 
Aleposomus,  Gn.i ,  American  Naturalist,  xvm,  1884,  433. 

Alepocephalids  with  body  elongate,  scaleless.  The  skin  is  thick,  finely  rugose,  with  a 
considerable  number  of  small  nodules  upon  the  belly,  and  sometimes  also  upon  the  sides 
and  the  lower  part  of  the  head.  Lateral  line,  wanting.  Mouth  moderate,  with  minute  teel  h 
upon  the  mandible  and  premaxillary.  Palatines,  tongue,  and  pharyngeal  bones  probably 
toothless.  Dorsal  and  anal  fins  opposite,  similar  in  form  and  equal  in  length.  Caudal 
probably  forked.     Vent  behind  the  middle  of  the  body.    Gill  openings  wide. 

There  are  two  species  in  this  genus:  A.  Copei,  Gill,  with  large  oval  orbit,  large  mouth, 
high  vertical  tins,  and  with  numerous  nodules  upon  the  sides,  and  A.  socialis  ( Vaillant),  with 
smaller  eye,  its  outline  projecting  above  the  dorsal  outline,  smaller  mouth,  and  nodules 
apparently  concentrated  on  the  lower  parts  of  the  head  and  the  anterior  portion  of  the  bell}'. 

ALEPOSOMUS  COPEI,  Gill.     (Figure  51.) 
Aleposomus  Copei,  Gill,  American  Naturalist,  win,  1884,  433. 

Body  compressed,  its  outlines  sloping  from  head  to  middle  of  the  caudal  peduncle; 
its  height  5.J  in  its  length. 

Length  of  the  head  3%  in  length  of  body.  Snout  short,  declivous,  its  length  half  the 
horizontal  diameter  of  the  eye  and  about  one-fifth  that  of  head.  Mandible  scarcely  extend- 
ing beyond  upper  jaw.  Maxillary  extends  to  vertical  from  middle  of  orbit.  Small  teeth 
upon  mandible  and  premaxillary.  Eye  very  large :  its  diameter  half  the  length  of  the  head ; 
its  upper  outline  does  not  project  above  the  dorsal  profile,  as  in  .1.  sodaUs.  Gill  opening 
large.  Skin  thick,  slimy,  no  lateral  line  distinguishable.  No  scales  present,  but  numerous 
tubercles  upon  the  sides  of  the  body.  None  arc  perceptible  on  the  head.  Vent  midway 
between  the  origin  of  the  ventral  and  the  tip  of  the  last  dorsal  ray.  Dorsal  origin  equidis- 
tant from  the  gill  opening  and  the  base  of  the  middle  caudal  rays;  highest  in  its  middle 
portion,  rounding  forward  and  behind.  Anal  inserted  immediately  under  the  dorsal;  simi- 
lar in  shape  and  equal  in  extent.  Caudal,  though  mutilated,  was  undoubtedly  emarginate, 
and  probably  forked.  Accessory  rays,  characteristic  not  only  of  A  leposomus  but  of  Xenoder- 
michthys,  are  not  conspicuous.  The  pectoral  is  inserted  very  low  down,  close  to  the  pos-

much  greater  than  half  the  diameter  of  the  eye.  The  ventral  origin  is  equidistant  from  the 
posterior  margin  of  the  eye  and  the  base  of  the  posterior  dorsal  ray ;  it  is  slender,  and  reaches 
nearly,  if  not  quite,  to  the  vent.    Color,  uniform  blackish. 

A  single  specimen  (No.  33551,  17.  S.  N.  M.),  3j  inches  in  length,  was  obtained  by  the 
Albatross  at  station  2099  in  37°  12'  20"  N.  lat.,  69°  39'  W.  Ion.,  at  a  depth  of  2,919  fathoms. 

ALEI'OSOMI'S  SOCIALIS,  i  Vaii.lant),  Goode  and  Beajs.     (Figure  58.) 

Xenodermiehthys  sucialis,  Vaillant,  Exp.  Sci.  Travailleur  et  Talisman,  18*8,  162,  pi.  xin,  fig.  1. 

Body  compressed,  with  upper  and  lower  outlines  parallel  for  the  greater  portion  of  their 
length.     Its  length  is  nearly  G  times  its  height. 

Head  one  fourth  of  leugth  of  body.  Snout  very  short,  hardly  one-fourth  length  of  the 
head,  while  the  mandible,  which  extends  considerably  beyond  the  upper  jaw,  is  nearly  half 
as  long  as  head.  The  maxillary  reaches  nearly  to  the  line  of  the  center  of  the  eye.  Small 
teetli  upon  the  mandible  and  premaxillary.  The  palatines,  the  tongue,  and  the  pharyngeal 
bones  are  toothless.  The  eye  is  enormous,  its  diameter  two-fifths  of  the  length  of  the  head. 
It  protrudes  above,  the  profile,  forming  a  protuberance  noticeable  either  at  the  side  or  from 
below.  Width  of  interorbital  space  scarcely  one-sixth  of  the  length  of  the  head.  Gill 
opening  large,  although  the  opercular  slit  does  not  reach  very  far  up,  its  upper  edge  beipg 
attached  to  the  body  by  a  membrane. 

In  the  fresh  individual  the  skin  was  slimy,  covered  by  a  thick  mucus,  so  that  the  lateral 
line  can  not  be  distinguished;  is  doubtless  merged  in  the  fold  between  the  upper  and  lower 
muscular  masses.     No  trace  of  scales.     Vent  situated  behind  middle  of  body. 

The  dorsal  extends  behind  the  caudal  peduncle;  it  is  not  very  high  and  is  slightly  raised 
posteriorly  in  relation  to  the  dorsal  outline.  The  anal  resembles  it  precisely  in  size  and 
shape;  the  caudal  is  deeply  emarginate,  and  is  preceded  above  and  below  by  very  distincl 
accessory  rays,  which  occupy  half  of  the  distance  between  the  dorsal  and  the  anal.  The 
paired  tins  are  but  little  developed,  short,  and  the  pectorals  have  about  Hi  rays. 

Color  uniformly  deep  blackish,  violet :  the  litis  seem  lighter  on  account  of  their  trans- 
lucency.  There  are  traces  of  black  spots  upon  the  membrane  of  the  anal,  and  also  under 
the  eye  upon  the  cheek  and  the  opercular  (lap,  and  these  continue  also  upon  the  belly; 
these  spots  are  more  conspicuous  in  the  specimen  when  it  is  preserved  than  when  it  is  fresh. 
The  iris  is  violet;  pupil  opaline.     ( Vaillcmt.) 

This  species  was  obtained  in  great  abundance  on  the  Banc  d'Arguin,  where  133  specimens 
were  obtained  in  one  haul,  at  a  depth  <>t'  1,230  meters.  It  was  also  obtained  in  small  numbers 
off  the  coast  of  Morocco  from  717  to  1,350  meters,  and  on  the  coast  of  Soudan  at  800  meters. 
Vaillant  seems  to  be  somewhat  uncertain  whether  or  not  this  form  belongs  to  the  genus 
Xenodermichthys,  aud  remarks  that,  comparing  it  with  the  diagnosis  of  Dr.  Giinther,  he  can 
see  nothing  which  absolutely  rules  it  out.  Assuredly,  the  skin  presents  no  traces  of  rugosities 
nor  of  any  growth  which  can  be  compared  to  scales  even  in  a  rudimentary  condition.  At,  all 
events,  it  can  be  readily  distinguished  from  Xenodermichthys  nodulosus  of  Giinther,  which 
has  an  arrangement  of  fins  very  different,  and  a  much  slighter  development  of  the  eye. 

As  Vaillant  says,  the  great  abundance  in  which  this  fish  was  taken  in  one  haul  of  the 
deep-sea  net  would  seem  to  indicate  that  it  occurs  in  large  schools  in  the  depths  of  ocean. 

Xenodermichthys  Giiii/litri,  Alcock,  Ann,  and  Mag.  Nat.  Hist.,  1892,  n,  357,  vol. 
xvili,  fig.  3,  from  Investigator,  station  133,  Indian  Ocean,  078  fathoms,  seems  likely  to 
belong  to  this  genus. 

LEPTODERMA,  Vaillant. 

Leptodenna,  Vaillant,  Exp.  Sci.  Travailleur  et  Talisman,  Poissons,  1888,  165. 

Body  elongate,  gradually  diminishing  posteriorly  until  it  becomes  almost  thread-like. 
Head  moderate,  but  (in  the  only  known  species)  with  enormous  eyes.  Mouth  small.  Teeth 
upon  premaxillaries  and  maxillaries.  A  distinct  submaxillary.  Dorsal  and  anal  elongate, 
extended  upon  the  caudal  peduncle  and  ending  slightly  in  advance  of  its  extremity,  the  tins 
very  much  larger  than  the  dorsal.     Gill  opening  wide,  though  not  very  high.    No  scales. 


DISCUSSION    OF    SPECIES   AND    THEIR    DISTRIBUTION.  49 

The  genus  is  closely  allied  iii  Xenodermichthys,  but  is  easily  distinguished  from  it  1>\  its 
general  appearance,  its  smaller  mouth,  and  by  the  great  inequality  in  the  extent  of  the  dor- 
sal and  anal  tins.  The  skin,  entirely  devoid  of  scales,  adheres  hut  slightly  to  the  tissues 
which  it  covers. 

LEPTODERMA  MACROPS,  \  aii.iani.     (Figure  56.) 

Leptoderma  maerops,  Vaili.ani,   Exp.  Sci.  Travailleur  el  Talisman,  Poissons,  105,  pi   xn,  fig.  2. — AXCOCK, 
Ann.  and  Mag.  Nat.   Hist..  1892,  II,  361. 

Mody  elongate,  its  greatest  height  just  behind  the  head  being  equal  to  one-tifteenth  of 
its  length,  and  its  thickness  at  the  same  place  in  about  the  same  proportion.  It  is  slightly 
thinner  about  its  middle,  and  posteriorly  the  compression  is  much  more  decided. 

Head  small  but  for  enormous  size  of  orbital  spheres;  its  length  one-fifth  that  of  the 
body;  snout  is  obtuse,  short,  its  length,  hardly  three-elevenths  of  distance  separating  its 
extremity  from  posterior  margin  of  opercular  (lap:  mouth  small,  the  maxillarynot  reaching 
nearly  back  to  the  line  of  the  anterior  margin  of  the  orbit.  Each  premaxillary  armed  with 
a  row  of  small  conical  teeth  to  the  number  of  about  four;  maxillary  toothless,  the  mandible 
armed  with  teeth  like  those  on  the  premaxillary,  slightly  developed,  scarcely  visible 
except  when  strongly  magnified;  no  teeth  on  the  palatines.  Iris  is  much  developed,  pro- 
truding; diameter  of  eye  is  three-eighths  length  of  head.     Gill  openings  wide  and  low. 

Ventral  far  forward,  at  a  distance  from  snout  equal  to  about  three-eighths  length  of 
body;  lateral  line  apparently  lacking;  the  tegument  is  so  delicate  that  it  has  been  impos- 
sible to  find  a  specimen  in  which  it  was  not  destroyed,  since  it  adhered  but  slightly  to  the 
muscular  tissues.  Dorsal  and  anal  very  low,  unequal  in  extent,  the  origin  of  the  former 
opposite  twenty-second  ray  of  the  latter,  both  terminating  at  about  the  same  vertical  and 
close  to  the  caudal.  All  the  rays  are  divided  and  articulated.  Caudal  but  slightly  devel- 
oped; pectoral  lanceolate;  ventrals  seemingly  connate. 

Color,  black,  velvety;  iris,  gray;  pupil,  opaline. 

Radial  formula:  D.  48;  A.  71;  V.  5. 

This  species  appears,  like  Xenodermichthys,  to  occur  in  large  schools  upon  the  Banc 
d'Arguin,  47  specimens  having  been  taken  in  one  haul  at  a  depth  of  1,495  meters.  Others 
were  obtained  in  the  same  locality  at  2,330  meters,  and  also  on  the  coast  of  Soudan  at  1,100 
meters,  and  the  coast  of  Morocco  at  1,163  to  1,23")  meters.  M.  Yaillant  complains  that  not- 
withstanding the  abundance  of  specimens  not  one  of  them  was  in  condition  for  description. 

The  Investigator  obtained  at  station  134,  in  the  Indian  Ocean,  753  fathoms,  a  fish  SjJ 
inches  long,  identified  by  Alcock  with  this  form. 

ANOMALOPTERUS,  Vaillant. 

Anomaloptt  nix,  Vaillant,  Exp.  Sci.  Travailkur  et  Talisman,  Poissons,  1888,  160. 

Body  oblong,  short;  head  very  large.  Teeth  upon  premaxillaries,  mandible,  and  pala- 
tines. Soft  dorsal  and  anal  upon  the  caudal  peduncle,  nearly  equal  in  extent,  the  former 
preceded  by  a  kind  of  adipose  fold  or  cushion,  occupying  the  entire  length  of  the  back  in 
front  of  it.    Gill  opening  broad  and  large.     Skin  naked. 

In  its  deprivation  of  scales  the  genus  resembles  Xenodermichthys  and  Leptoderma,  from 
which,  however,  it  is  distinguished  by  its  general  form  and  by  the  adipose  ante  dorsal  cush- 
ion, which  occurs  in  no  other  genus. 

ANOMALOPTERUS   PINGUIS,  Vaillant.     (Figure  54.) 

Anomalopierui  pinguis,  Vaillant.  Exp,  Sci,  TtavaiUeur  et  Talisman,  Poissons,  1888,  160. 

Head  nearly  half  entire  length  of  body;  length  of  snout one-third  that  of  the  head.    Mouth 

very  wide,  the  maxillary  extending  beyond  perpendicular  from  posterior  margin  of  orbit. 

Upper  jaw  and  mandible  armed  with  small  teeth;  stronger  teeth  upon  palatines;  none  upon 

the  vomer  (the  small  size  of  the  individual  examined  renders  it  impossible  to  be  absolutely

sure  of  this  fact).  Eye  surrounded  by  a  cutaneous  fold,  which  in  a  fresh  specimen  narrows 
it  very  much,  so  that  it  measures  only  about  one-twentieth  of  the  length  of  the  head.  (The 
size  of  the  eye  seems  much  greater,  however,  in  a  specimen  preserved  in  spirits.)  Gill  open- 
ing wide;  the  operculum  covered  in  life  by  a  membranaceous  tegument. 

Skin  naked.  The  lateral  line  begins  at  upper  angle  of  gill  opening,  descending  rapidly 
to  median  line,  after  which  it  falls  to  the  base  of  the  caudal. 

Dorsal  occupies  four  fifths  of  the  length  of  the  back,  beginning  above  the  upper  angle 
of  the  gill  opening.  Its  anterior  portion  (two-thirds  of  its  entire  length)  is  composed  of  a 
low,  cutaneous,  adipose,  fold  or  cushion,  while  its  posterior  portion  is  a  true  fin  supported  by 
rays.  Anal  extends  to  posterior  portion  of  dorsal,  though  a  little  shorter  and  extending  a 
little  further  posteriorly.  Caudal  slightly  emargiuate,  and  equal  in  length  to  about  one- 
sixth  of  the  length  of  the  body.  Pectorals  very  short;  the  origin  almost  under  that  of  the 
rayed  portion  of  the  dorsal.  • 

Color  bluish ;  iris  white. 

Radial  formula:  D.  17;  A.  14;  P.  9;  V.  !>. 

The  unique  representative  of  this  species  was  obtained  off  the  coast  of  Morocco,  in 
1,400  meters.  It  is  very  small,  and  the  action  of  alcohol  has  distorted  it  Aery  much.  Hap- 
pily a  sketch  made  from  the  fresh  specimen  has  enabled  M.  Vaillant  to  give  a  figure  and  a 
quite  minute  description.  The  length  of  the  body  is  scarcely  GO  millimeters;  its  height  is 
about  one-fifth  of  its  length,  and  its  thickness  is  still  less. 

AULASTOMATOMORPHA,  Alcock. 

Aulastomatomorpha,  Ai.cock,  Aim.  and  May.  Nat.  Hi>t..  vi,  307,  (Oct.  1890),  vn,  10,  Jan.  1891,  with  outline 
figure.     Type,  A.  phospliorops. 

Body  elongate,  covered  with  minute,  hardly  imbricate  scales.  Head  naked.  Anterior 
bones  of  head  produced  intoalongtube  terminating  in  a  narrow  month.  .Margin  of  upper  jaw 
formed  by  premaxillarics  and  mamillaries.  Teeth  uniserial  and  in  the  jaws  only.  Eye 
large.  Gill  cover  apparently  complete.  Gill  opening  wide  below,  contracted  above,  its 
upper  angle  nearly  on  the  level  of  the  pectoral  fin.  Gills  4,  with  narrow  laminae.  Pseudo- 
branchiae  rudimentary.  Dorsal  fin  upon  the  caudal  peduncle.  No  adipose  dorsal.  Anal  fin 
very  long.    Caudal  forked.     Pyloric  caeca  few,  small.    No  air  bladder. 

This  genus  is  characterized  especially  by  the  rudimentary  pseudobranchise,  and  the 
prolongation  of  the  anterior  bones  of  the  head  into  a  snout,  like  that  of  Aulostoma. 

The  type  of  the  species  is  A.  phosphorous,  Alcock  (1.  e.),  obtained  by  the  Investigator  in 
the  Arabian  Sea,  station  104,  at  a  depth  of  1,000 fathoms;  a  single  specimen,  believed  to  be  an 
adult  male,  11  inches  in  length.  (Figure  55.)  Alcock  remarks  that  the  head  of  this  unique 
fish  is  covered  throughout  by  a  thick,  spongy,  glandular  skin,  with  dazzling  white  reflec- 
tions, which  is  probably  luminous  in  function.  The  eyes  are  very  large  and  extremely 
prominent. 

Family  PTEROTHRISSID^E,  Goode  and  Bean. 

Bathythrissidw,  Gunther,  Challenge!  Report,  xxu,  1887,  220. 

Body  oblong,  with  rounded  abdomen,  covered  with  cycloid  scales;  head  naked;  bar- 
bels none.  Margin  of  the  upper  jaw  formed  by  the  iutermaxillaries  mesially,  and  by  the 
maxillaries  laterally.  Opercular  apparatus  complete.  Adipose  fin  absent;  dorsal  fin  much 
elongate,  many-rayed;  anal  flu  short.  Stomach  with  blind  sac;  pyloric  appendages  numer- 
ous. Gill  apparatus  well  developed;  pseudobranchise;  gill  openings  wide;  an  air  bladder. 
Ova  very  small;  ovaries  without  duct.     (Giinther.) 

Theuame  of  the  genus  proposed  by  Giinther  falls  into  synonymy,  and  the  family  name 
is,  in  accordance  with  common  usage,  chauged  to  correspond  to  that  of  the  typical  genus.

This  form  is  abundant  in  shallow  water  in  the  Mediterranean  and  Adriatic,  where  it  is 
often  taken  by  the  fishermen.  It  is  kuowu  also  oft  Portugal  and  in  the  northeastern  Atlan- 
tic from  Scotland  to  61°  and  beyond.  In  Norwegian  waters  it  occurs  in  the  depths,  Collett 
haviug  obtained  it  in  200  fathoms.  This  distribution  is  paradoxical,  and  is  referred  to  in 
another  place. 

A.  sphyrcena  spawns  in  April  in  the  Mediterranean. 

Giinther  considers  A.  decagon  from  Eokitika,  New  Zealand,  to  be  the  same  form. 
Giglioli,  after  studying  an  extensive  series  obtained  by  him  at  Messina,  has  decided  that

This  form  occurs  in  Norway  at  depths  of  It'll  fathoms  ami  less.  The  first  taken  in  North 
America — the  type,  of  A.  syrtensium,  Goode  and  Bean  (U.  S.  X.  M  ,  No.  21624) — was  found 
in  the  stomach  of  a  Phycis  from  Sable  Island  Bank,  in  200  fathoms.  In  July,  1891,  a 
specimen  18  inches  long  (TJ.  S.  N.  M..  No.  4370S)  was  caught  by  a  boy  with  a  hook  and  line 
in  the  harbor  of  Belfast.  Mr.  Another.  No.  37801,  15  inches  long,  was  taken  at  Biddefbrd

The  family  Microstomia,  although  never  formally  defined  by  Dr.  Gill,  is  evidently  a 
valid  one.  separated  from  Argentinidce  by  the  much  smaller  number  of  branchiostegal 
rays,  only  three  or  tour,  instead  of  six  to  eight, as  in  Argentinidce.    The  advanced  position 

of  the  ventrals  is  a  collateral  character.

Microstomids,  with  small  mouth,  small  intermaxillaries,  short  and  broad  mamillaries. 
Small  teeth,  in  narrow  series  in  lower  jaw,  and  on  head  of  vomer.  Ventrals  in  front  of  dor-

Air  bladder  large.     Scales  large,  thin,  silvery.     Adipose  tin  absent  in  adults. 

"The  evidence  as  to  the  bathybial  habits  of  these  small  fishes,"  writes  Gunther,  "is 
merely  circumstantial.  They  seem  to  have  the  same  vertical  range  as  Argentina,  but  are 
more  rarely  seen  in  collections,  as  the  small  size  of  their  slender  cylindrical  body  renders 
their  capture  very  difficult."

Family  BATHYLAGID^. 

Bathylagidce,  Gill,  Science,  in,  620,  1884.     (Name  only.  I 

The  family  Bathylagidce  of  Gill  was  formed  for  the  genus  Bathylagus  of  Gunther.  This 
genus  includes  live  species  of  small  fishes,  one  of  them  (/»'.  atlanticus)  occurring  in  the 
Atlantic  in  depths  as  great  as  2,040  fathoms,  another  ( /.'.  antarcticus)  inhabiting  the  Ant- 
arctic Ocean  at  a  depth  of  1,950  fathoms,  and  a  third  (B.pacificus)  occurring  off  the  coast. 


54  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

of  Washington  in  685  to  877  fathoms.  All  of  these  species  were  apparently  black  in  life. 
In  all  of  them  the  eye  is  large  and  is  believed  to  be  intended  for  the.  utilization  of  phosphor- 
escent light  produced  by  other  animals  of  the  deep  sea.  These  fishes  are  not  predaceous. 
Their  bones  are  very  thin,  the  fin  rays  feeble,  and  the  scales  easily  deciduous.  Dr.  Giinther 
considers  Bathylagus  nearly  allied  to  Microstoma. 

Mr.  Murray  has  made  a  very  important  observation  on  the  circumstances  attending  the 
capture  of  this  fish,  which  has  direct  bearing  on  the  question  as  to  the  bathybial  range  of 
many  of  the  fishes  captured  by  the  deep  sea  trawl.  At  this  station  the  trawl  was  over  the 
side  seven  hours,  but  it  never  seemed  to  touch  the  bottom.  Yet  it  contained,  besides  the 
specimen  of  Bathylagus,  several  large  Medusas  several  bright  scarlet  shrimps,  and  other 
animals.  ''  It  is  impossible  to  say  how  near  the  trawl  may  have  been  to  the  bottom,  but 
Mr.  Murray  considers  it  quite  certain  that  most,  if  not  all,  of  the  animals  above  mentioned 
were  captured  in  the  intermediate  water,  between  a  depth  of  100  fathoms  from  the  surface 
and  a  short  distance  from  the  bottom."' 

"Notwithstanding  this  circumstance,''  says  Giinther,  "  the  thinness  of  the  bones,  the 
fragility  of  the  fin  rays,  the  delicacy  of  the  skin  and  scales,  and  the  enormously  large  eyes, 
seem  to  be  sufficient  evidence  that  these  fishes  are  actually  inhabitants  of  very  great  depths, 
although  there  may  be  reasonable  doubts  as  regards  the  exact  depth  at  which  Bathylagus 
atlanticus  was  obtained.  These  fishes  must  therefore  be  entirely  dependent  tor  vision  on 
the  phosphorescent  light  which  is  produced  by  other  abyssal  creatures.  Not  being  fish  of 
prey  themselves,  or  only  to  a  slight  degree,  they  would  be  attracted  by  the  light  issuing 
from  the  Pediculates  and  Stomiatids  of  the  deep,  and  thus  fall  an  easy  prey  to  these  fishes."

Body  oblong,  compressed,  covered  with  thin  deciduous  scales  of  moderate  size.  No 
phosphorescent  organs.  Head  short,  rather  compressed,  with  thin  membranaceous  bones. 
Mouth  very  narrow,  transverse,  anterior;  the  margin  of  the  upper  jaw  is  formed  by  the 
intermaxillary  and  maxillary,  which  is  short  dilated.  Teeth  on  the  intermaxillary  rudi- 
mentary; those  of  the  lower  jaw  extremely  small,  implanted  on  the  edge  of  the  bone,  form- 
ing a  minute  serrature;  a  series  of  minute  teeth  across  the  vomer  and  along  the  palatine. 
Eye  very  large.  Pectoral  and  ventral  fins  developed;  the  latter  seven-rayed  and  inserted 
opposite  to  the  dorsal,  at  a  considerable  distance  from  the  pectoral.  Dorsal  fin  in  the  mid- 
dle of  the  length  of  the  body ;  adispose  fin  small,  not  very  far  from  the  caudal.  Anal  fin  of 
moderate  length  or  many  rayed.  Gill  opening  narrowed,  commencing  opposite  to  the  root 
of  the  pectoral,  and  extending  across  the  isthmus,  the  gill  membranes  being  united  and  not 
attached  to  the  isthmus.  GUI  rakers  lanceolate,  rather  long;  gills  small;  pseudobrauchue 
well  developed.

The  height  of  the  body  is  a  little  less  than  the  length  of  the  bead,  which  is  one-fourth

rior  profile  and  transverse  anterior  mouth,  the  clefl  of  the  moutb  being  nearly  on  the  same 
level  as  the  lower  margin  of  the  eye.  All  the  bones  of  the  head  are  very  thin,  semicarti 
laginons;  the  head  seems  to  have  been  scaleless.  The  gill  cavity  is  closed  behind,  the  gill 
opening  beginning  opposite  to  the  runt  of  the  pectoral  fin,  and  the  gill  membrane  forming  a 
broad  bridge  across  the  isthmus.  This  membranous  bridge  is  not  attached  to  the  isthmus 
and  contains  a  layer  of  transverse  muscular  fascicles,  by  which  the  gill  covers  can  be  simul- 
taneously firmly  closed.  The  branchiostegals  are  extremely  thin  and  short  and  hidden  in 
the  membrane.  The  dorsal  tin  commences  nearly  midway  between  the  snout  and  caudal: 
it  is  short  and  composed  of  feeble  rays.  Vent  placed  far  backwards,  the  length  of  the  tail 
not  being-  much  more  than  that  of  the  head.  Anal  lin  likewise  composed  of  feeble  rays, 
terminating'  at  a  short  distance  from  the  caudal.  The  caudal  tin  is  too  much  injured  to 
ascertain  its  shape.  Pectoral  tin  narrow,  close  to  the  lower  profile.  Ventrals  opposite  to 
the  hind  pari  of  the.  dorsal  tin. 

All  the  scales  being  lost,  their  size  and  number  can  be  given  only  approximately  from 
the  remaining  scale  pouches;  they  must  have  been  very  thin,  and  the  lateral  line  seems  to 
have  run  along  the  middle  of  the  side  of  the  body.  Of  the  color  nothing  can  be  stated, 
except  that  the  scale  pouches  have  a  distinct  black  margin.     ( GHinther.)

BATHYLAGUS  EURYOPS,  Goode  and  Bean,  n.  s.     (Figure  63.)

head  without  snout),  the  length  of  the  head  being  one-fourth  of  the  total  (without  caudal). 
The  diameter  of  the  eye  is  one-half  the  length  of  the  head;  width  of  the  interorbital  space  a 
little  more  than  one-half  the  diameter  of  the  eye.  Snout  very  short;  steep  profile;  itsangle 
on  a  level  with  the  lower  margin  of  the  eye.  All  the  bones  of  the  head  very  thin,  semicar- 
tilaginous.  Gill  apparatus  as  in  the  other  species.  Dorsal  fin  feeble,  nearer  tip  of  snout 
than  root  of  caudal.  The  vent  far  back,  the  length  of  the 'tail  not  being  much  more  than 
that  of  the  head.  Anal  tin  feeble,  distance  of  its  insertion  from  the  end  of  the  base  of  the

BATHYLAGUS  BENEDICTI,  Goodk  and  Bean,  n.  a.     (Fignre  64.) 

This  species  is  in  some  respects  intermediate  between  B.  atlanticus  and  1>.  antarcticus. 
The  height  of  the  body  is  nearly  equal  to  the  length  of  the  head,  which  is  two  ninths  of  the 
total  (without  caudal).  The  diameter  of  the  eye  is  one-half  the  length  of  the  head,  as  in 
the  other  species.  The  width  of  the  interorbital  space  is  less  than  two-thirds  of  that  of  the 
eye  (proportionately  narrower  than  in  the  other  species).  Snout  very  short,  its  length 
about  one-fourth  the  diameter  of  the  eye.  Mouth  short,  its  angle  being  about  on  a  level 
witli  the  lower  margin  of  the  eye.  Bones  of  head  thin,  semicartilaginous ;  head  apparently 
scaleless;  no  traces  of  scales  in  the  specimens  before  us.  dill  cavity,  membranes,  and 
branchiostegals  as  in  the  other  species.  The  origin  of  the  dorsal  lin  is  nearer  to  the  end  of 
the  snout  than  to  the  base  of  the  caudal,  and  equidistant  between  the  snout  and  the  adi- 
pose fin;  its  length  equal  to  two-fifths  of  the  length  of  the  head.     Vent  placed  farther  for-

ward  than  in  B.  atlanticus,  the  length  of  the  postanal  portion  of  the  body  being  greater 
than  that  of  the  head,  and  contained  3J  times  in  the  total  without  caudal.  The  ventral  fins 
are  placed  opposite  the  posterior  portion  of  the  base  of  the  dorsal. 

Although  the  scales  have  all  disappeared,  it  would  seem  that  there  had  been  about  32 
longitudinal  rows;  and  their  size  may  be  judged  of  by  the  fact  that  there  were  7  rows 
between  the  base  of  the  pectoral  and  the  vertical  from  the  origin  of  the.  ventral.  Adipose

Body  elongate,  subcylindrical.  Head  depressed,  the  snout  triangular,  rather  pointed. 
Interorbital  region  transversely  concave.  Mouth  very  wide;  premaxillary  not  protractile, 
long  and  strong,  more  than  half  length  of  the  head;  maxillary  closely  connected  with  it, 
very  small  or  obsolete.  Premaxillary  with  one  or  two  series  of  large  compressed  knife-

projection  above  the  eye.  Pseudobranchiae  well  developed.  Gill  rakers  very  small,  spine- 
like. Gill  membranes  slightly  connected.  Top  of  head  naked.  Cheeks  and  opercles  scaled 
like  the  body.  Body  covered  with  rather  small,  adherent,  cycloid  scales.  Lateral  line  pres- 
ent. No  phosphorescent  spots.  Dorsal  tin  short,  rather  anterior.  Pectorals  moderate, 
inserted  high.  Ventrals  anterior,  not  far  behind  pectorals,  large,  the  inner  rays  longer

with  a  long,  blind  sac  and  many  pyloric  caeca.     (Jordan.) 

The  genus  has  the  appearance  of  being  well  suited  for  deep-water  life,  and  its  near  allies 
are  some  of  the  most  characteristic  of  the  bathybial  forms.

Saurus  trivirgatus,  Valenciennes,  Poiss.,  Isles  Canaries,  72,  pi.  xv,  fig.  1  (good). 

Length  of  head  -t  in  total,  snout  broader  than  long,  pointed,  with  jaws  equal  anteriorly, 
or  with  the  upper  jaw  slightly  projecting.  Dorsal  slightly  higher  than  the  length  of  its  rear 
base.  Pectorals  extend  to  ninth  or  tenth  scale  of  lateral  line.  Scales  upon  the  tail  slightly 
cariuate.    Color  dusky  gray  above,  yellow  below.    D.  11-12;  A.  11-12.    Scales  3i  |  58-62  |  0. 

This  form,  the  type  of  the  genus  Haunts,  C.  and  V.,  is  closely  allied  to  uEsox  synodus," 
Linn.,  the  type  of  Synodus,  Schn.,  which  is  quite  as  likely  to  have  been  the  common  Ameri- 
can Synodus  /ceteris  as  any  other  form. 

This  form,  rare  in  the  Mediterranean,  occurs  also  about  St.  Vincent,  Madeira,  and  the 
Canaries,  and  has  been  taken  by  the  authors  at  Bermuda,  where  it  is  known  as  the  "Snake 
Fish."  It  occurs  at  moderate  depths  about  Bermuda,  but  probably  below  the  hundred- 
fathom  line.  No  observations  have  been  made  in  regard  to  its  bathic  range.  S.kaianus, 
Gunther,  occurs  about  the  Ki  Islands  at  140  fathoms;  and  Giinther  is  of  the  opinion  that  S. 
atlantieus,  Johnson,  aMadeiran  form,  and  >S.  intermedins,  Spix.  from  tropical  American  waters, 
also  range  into  deep  water.  Others  are  likely  to  do  so.  So  is  Saurida,  an  Indo-Pacific 
genus. 

BATHYLACO,  Goode  and  Bean,  n.  g. 

Body  subeylindrical,  rather  elongate,  stout,  similar  in  form  to  Synodus.  (Scales  are 
absent  in  the  specimen  studied,  and  it  is  not  even  possible  to  determine  whether  or  not  this 
is  a  naked  species.)  Head  conical.  Snout  short.  Mouth  very  large,  wide,  oblique,  lower 
jaw  slightly  projecting.  .Maxillary  narrow  and  long,  with  small  teeth,  which  are  somewhat 
biserial  in  front,  and  uniserial  behind;  interrupted  at  the  symphysis.  Mandible  with  a 
narrow  band  of  similar  teeth.  Palatine  teeth  in  a  narrowband;  tongue  toothless.  Eye 
moderately  large,  very  tar  forward,  its  upper  edge  (dose  to  the  dorsal  profile.  Pectoral 
small,  placed  low.  Ventral  nearly  median,  a  little  in  advance  of  the  dorsal  and  far  behind 
the  pectoral,  with  8  rays.  Dorsal  origin  nearly  in  the  middle  of  the  length  and  extending 
to  above  the  middle  of  the  anal.  Adipose  fin  probably  absent.  The  anal  origin  far  back, 
tin  short,  (iill  opening  very  wide,  as  in  Bathysaurus,  the  left  membrane  overlapping  the 
right,  not  attached  to  the  isthmus.  Branchiostegals  numerous,  trill  rakers  short  and  few. 
Opercular  bones  very  thin  and  feeble. 

BATHYLACO  NIGRICANS,  Goode  and  Beax,  n.  s.     (Figure  69.) 

The  length  of  the  head  one-fourth  of  total  (without  caudal);  its  depth  one-half  its 
length.  Snout  scarcely  more  than  one  half  the  diameter  of  tin'  eye,  and  contained  about  * 
times  in  the  length  of  the  head.  The  lower  jaw  the  longer.  The  eye  is  contained  4.;  times 
in  the  length  of  the  head,  its  diameter  equal  to  the  width  of  the  interorbital  space.  The 
intermaxillary  is  nearly  two-thirds  the  length  of  the  head.     The  mandible  is  contained  3

times  in  the  distance  from  the  tip  of  the  snout  to  the  origin  of  the  dorsal.  Dorsal  fin 
inserted  at  a  distance  from  the  tip  of  the  snout  equal  to  twice  the  length  of  the  head,  the 
length  of  its  base  nearly  one-third  of  total  (without  caudal).  The  anal  origin  is  under  the 
posterior  third  of  the  dorsal,  the  length  of  its  base  equal  to  half  that  of  the  head.  Pecto- 
ral small,  placed  low,  immediately  back  of  the  branchial  opening;  apparently  few-rayed. 
Color,  black. 

Radial  formula:  B.  8;  D.  20;  A.  10;  V.  8;  P.  6. 

The  condition  of  the  specimen  is  very  bad,  and  it  is  only  the  desire  to  call  attention  to 
this  interesting  form  that  induces  us  to  give  it  a  name. 

A  single  specimen,  8J  inches  in  length,  was  taken  by  the  Bhtke  off  Santa  Cruz,  at  a 
depth  of  2,393  fathoms. 

BATHYSAURUS,  Gunther. 

Bathysaitrus,  Gunther,  Ann.  and  Mag.  Nat.  Hist.,  August,  1878,  181;  Challenger  Report,  xxn,  181. 

Shape  of  the  body  similar  to  that  of  Saurus,  subcylindrical,  elongate,  covered  with 
small  scales.  Head  depressed,  with  the  snout  produced,  flat  above.  Cleft  of  the  mouth 
rather  wide,  with  the  lower  jaw  projecting;  intermaxillary  very  long,  styliform,  tapering, 
not  movable.  Teeth  in  the  jaws  in  broad  bands,  not  covered  by  lips,  curved,  unequal  in 
size,  and  barbed  at  the  end.  A  series  of  similar  teeth  runs  along  the  whole  length  of  each 
side  of  the  palate,  a  few  teeth  on  the  tongue,  and  groups  of  small  ones  on  the  hyoid.  Eye 
of  moderate  size,  lateral.  Pectorals  of  moderate  length.  Ventral  s  rayed,  inserted  imme- 
diately behind  the  pectoral.  Dorsal  fin  in  the  middle  of  the,  length  of  the  body,  with  about 
18  rays.  Adipose  fin  absent  or  present.  Anal  of  moderate  length.  Caudal  emarginate. 
Gill  openings  very  wide,  the  gill  membranes  being  separate  from  each  other  and  from  the 
isthmus.  Eleven  or  twelve  branchiostegals.  Gill  laminre  well  developed,  separate;  gill 
rakers  tubercular;  pseudobranchise  well  developed.     (Uiinther.)

ica, 1885,  40. 

Body  very  elongate,  subcylindrical,  with  depressed  head  and  tapering  tail,  its  greatest 
height  contained  7  times  in  its  length,  without  caudal,  and  8  times  in  the  length  to  tip  of 
upper  caudal  lobe;  its  greatest  width  9  times  in  standard  length;  its  height  at  origin  of 
anal  about  half  its  greatest  height;  length  of  caudal  peduncle  equal  to  greatest  height  of 
body. 

Scales  irregularly  ovate,  with  the  free  portion  convex,  thin,  cycloid,  leathery,  deciduous; 
those  in  middle  (it  body  with  a  vertical  diameter  nearly  equal  to  that  of  the  pupil;  those  of 
lateral  line  with  posterior  margin  truncate.  In  the  lateral  line,  which  extends  upon  the 
caudal  fin,  descending  below  the  median  line  of  the  body  near  the  origin  of  this  fin,  are 
78  specialized  scales,  larger  than  those  of  the  body.  Between  the  dorsal  fin  and  the  lateral 
line  are  about  8  rows  of  scales;  between  the  latter  and  the  anal  fin  are  about  the  same 
number. 

Head  twice  as  long  as  the  greatest  height  of  the  body7,  strongly  depressed,  alligator- 
like, naked  except  upon  the  cheeks  and  a  small  area  on  the  occiput,  with  strong  nasal  and 
interorbital  ridges.  The  greatest  width  is  somewhat  more  than  half  its  greatest  length, 
the  width  of  interorbital  area  nearly  equal  to  one  fourth  the  length  of  the  lower  jaw.  The 
length  of  the  snout  is  equal  to  twice  the  horizontal  diameter  of  the  eye.  The  anterior  nos- 
trils are  situated  midway  between  the  tip  of  the  snout  and  the  anterior  margin  of  the  orbit. 
The  cleft  of  the  mouth  is  enormous,  its  angle  posterior  to  the  eye  by  a  distance  about  equal 
to  the  width  of  the  interorbital  space.  The  length  of  the  upper  jaw  equals  one-sixth  of  the 
standard  body  length ;  that  of  the  lower  jaw,  one  fifth.  The  margin  of  the  upper  jaw  (formed 
by  the  intermaxillary  only)  is  armed  with  two  irregular  rows  of  depressible  teeth,  some  of 
which  are  barbed;  those  in  the  inner  row  are  much  the  largest,  many  of  them  being  two-

thirds  as  long  as  the  horizontal  diameter  of  the  pupil  and  twice  as  long  as  those  in  the 
outer  series.  The  lower  jaws  are  enormously  strong,  and  broad,  Battened  below,  the  width 
measured  on  the  under  surface  of  the  head  equal  to  t  wo  t  birds  t  he  width  of  t  he  broad  inter- 
orhital  space  The  lower  jaw  projects  outside  of  the  upper  jaw  at  the  sides  a  distance 
apparently  equal  to  half  its  width,  and  considerably  in  front;  the  lower  jaws  are  thickly 
studded  with  dcpressiiile  teetli,  many  of  them,  especially  the  larger  inner  ones,  strongly 
barbed,  those  in  trout claw  -like,  recurved.  On  the  palatines,  three  rows  of  teeth,  the  mid 
die  ones  very  much  enlarged  and  most  of  them  strongly  barbed — these  being  the  largest  of 
all  the  teeth.  On  the  tongue  a  tew  weaker  teeth,  and  groups  of  similar  teeth  upon  the 
vomer.     (Jill  lamina',  gill  rakers,  and  pseudobranchiae  as  described  by  Dr.  Gunther. 

The.  dorsal  tin  contains  17  rays,  and  is  inserted  at  a  distance  from  the  tip  of  the  snout 
equal  to  the  length  of  its  own  base,  and  slightly  greater  than  one-third  of  the  standard 
body  length.  The  fourth  or  longest  ray  is  equal  in  length  to  the  greatest  height  of  tin; 
body.  The  first  ray  is  a  rudiment;  the  second  is  nearly  half  as  long  as  the  third;  the  third 
slightly  shorter  than  the  fourth;  after  the  fourth  the  rays  diminish  rapidly  in  length  to  the 
ninth,  which  is  about  half  as  long  as  the  lower  jaw,  and  subsequent  to  which  the  diminution 
is  gradual;  the  last  ray  is  about  as  long  as  the  first. 

There  is  no  adipose  dorsal;  if  ever  present,  it  was  obliterated  before  the  specimen  came 
into  our  possession. 

The  anal  fin  contains  11  rays,  and  is  inserted  considerably  behind  the  vertical  from 
the  termination  of  the  dorsal,  at  a  distance  equal  to  the  horizontal  diameter  of  the  eye;  the 
length  of  its  base  is  equal  to  half  that  of  the  dorsal,  the  length  of  its  longest  ray  (the  third) 
equal  to  that  of  the  eighth  of  the  dorsal. 

The  caudal  is  slightly  forked,  its  middle  rays  two-thirds  as  long  as  those  in  the  upper 
lobe,  and  about  equal  to  the  seventh  dorsal  ray. 

The  pectoral  fin  consists  of  15  rays,  is  inserted  under  the  fourth  scale  of  the  lateral 
line,  and  at  a  distance  iu  front  of  the  dorsal  equal  to  half  the  greatest  height  of  the  body. 
Its  length  is  equal  to  that  of  the  lower  jaw,  and  the  seventh  ray  is  prolonged  to  a  length 
equal  to  that  of  the  head,  its  tip  extending  to  the  perpendicular  from  the  twelfth  dorsal  ray. 

The  ventral  is  composed  of  8  rays,  and  its  base  is  almost  entirely  in  advance  of  the 
perpendicular  from  the  origin  of  the  dorsal;  its  length  equals  half  that  of  the  head.  The 
two  ventrals  are  far  apart.

A  specimen  (Xo.  38100,  U.  8.  X.  M.),  264  inches  in  length,  was  obtained  by  the  Albatross 
from  station  2710,  in  a  depth  of  981  fathoms.  A  specimen  (No.  33305,  I'.  S.  X.  M.),  104 
inches  in  length,  was  taken  by  the  Albatross  from  station  2051,  in  1,106  fathoms.  Another, 
S.J  inches  in  length,  was  taken  by  the  A Ibatross  from  station  2550,  in  1,081  fathoms,  and 
another  from  station  2104,  in  991  fathoms. 

Vaillant  identified  a  specimen  obtained  off  the  coast  of  Morocco,  in  2,200  meters,  with 
B.  Agassizii.  Gunther  originally  described  the  species  from  a  specimen  taken  by  the  Chal-

Chlorophthalmus  Agassizii,  tii  nther,  Challenger  Report,  xxu,  192,  pi.  L.  C. 

Body  terete,  its  height  6^  iu  its  length,  its  width  1$.  The  least  height  of  the  tail  is 
half  that  of  thebody.  The  scales  are  moderately  strong,  sharply  pectinated  at  the  edge,  and 
arranged  iu  regular  transverse  rows,  overlapping  in  such  a  manner  as  to  resemble  oblique 
plates  upon  the  sides.    The  lateral  line  is  prominent,  straight,  containing  about  48  scales. 


DISCUSSION    OF    SPECIES    AND   THEIR   DISTRIBUTION.  61 

Between  the  Literal  line  and  the  origin  of  fche  dorsal  aiciiA  scales,  the  origin  of  the  ventral 
(J.  The  greatest  length  of  the  head  to  the  end  of  the  flexible  flap  of  the  operculum  slightly 
exceeds  one  fourth  of  the  body  length,  and  is  itself  slightly  more  than  4  times  the  Length  of 
the  snout.  The  longitudinal  diameter  of  the  orbit  is  l  times  thai  of  the  interorbital  space 
and  enters  3  in  length  of  head.  The  maxillary,  broad  and  flattened  posteriorly,  is  in  length 
one-tenth  of  the  body,  and  extends  back  to  perpendicular  from  the  anterior  margin  of  the 
pupil.  The  articulation  of  the  mandible  is  in  advance  of  the  posterior  tip  of  the  maxillary, 
its  length  slightly  greater,  and  it  protrudes  beyond  the  snout,  when  the  mouth  is  open,  a 
distauee  greater  than  the  width  of  the  interorbital  area.  When  the  mouth  is  closed  its  tip 
still  projects  noticeably. 

The  dorsal  tin  is  located  almost  midway  between  the  snout  and  the  adipose  dorsal.  Its 
height  is  almost  equal  to  that  of  the  ventral.  The  adipose  dorsal  is  over  the  middle  of  the 
anal,  its  length  half  the  diameter  of  the  orbit. 

The  distance  of  the  anal  from  the  snout  is  about  three-fourths  of  the  body  length.  Its 
length  of  base  is  equal  to  the  length  of  the  snout;  its  height  to  that  of  the  middle  caudal 
lays.  The  caudal  is  furcate.  The  pectoral  is  long,  subfalcate,  inserted  close  to  the  bran- 
chial (deft,  its  tip  extending  to  the  fourteenth  or  fifteenth  scale  of  the  lateral  line,  its  length 
twice  that  of  the  mandible. 

The  ventral  is  located  two-fifths  of  the  way  from  the  snout  to  the  base  of  the  caudal, 
and  directly  under  the  middle  of  the  dorsal. 

Radial  formula:  D.  11  +  1;  A.  S;  (J.  10;  P.  17  or  18;  V.  9  or  10;  L.  hit.  about  48. 

Color  grayish  mottled  with  brown,  scales  metallic,  silvery. 

Specimens  were  obtained  by  the  Fish  Hit  irk  in  five  localities  ranging  in  depth  from  101 
to  156  fathoms,  and  by  the  Albatross  from  eleven  stations  at  depths  of  from  85  to  167 
fathoms. 

fl.  chalybeius  is  not  identical  with  C.  Agassi~ii,  but  is  well  separated  by  the  smaller  eye, 
longer,  more  conical  snout,  lower,  more  terete  body,  and  larger  scales.  It  closely  resembles 
it,  however,  in  general  form.  Dr.  Giinther's  diagnosis  of  ('.  Agassizii  in  the  Challenger 
volume  more  nearly  applies  to  C.  chalybeius,  and  his  figure  is  apparently  of  C.  ohalybeius. 

C.  product  m,  Giinther,  was  obtained  off  the  Fiji  Islands,  at  a  depth  of  315  fathoms. 

('.  nigripinnis,  Giinther,  is  known  only  from  a  single  individual,  taken  bythe  Challenger 
off  Twofold  Bay,  at  a  depth  of  120  fathoms. 

CHLOROPHTHALMUS  TRUCULENTUS,  Goode  and  Beax,  n.  s.     (Figure  72.) 

Body  subterete,  somewhat  compressed,  its  height  5A  in  its  length,  its  width  about  8. 
The  least  height  of  the  tail  is  contained  about  2$  in  the  greatest  height  of  the  body  at  the 
insertion  of  the  dorsal.  Scales  moderate,  cycloid,  arranged  in  regular  transverse  rows, 
overlapping  in  such  manner  as  to  resemble  oblique  plates  on  the  sides.  The  lateral  line  is 
rather  inconspicuous,  containing  between  40  and  50  scales  (on  account  of  denuded  condition 
of  body,  an  accurate  enumeration  can  not  be  made).  There  are  about  6  scales  between 
the  lateral  line  and  the  origin  of  the  dorsal,  and  6  or  7  between  it  and  the  ventral.  The 
greatest  length  of  the  head  from  the  tip  of  the  projecting  lower  jaw  is  a  little  more  than 
one-third  of  the  length  of  the  body,  and  is  contained  1'A  times  in  the  length  of  the  snout. 
The  lower  jaw  projects  beyond  the  tip  of  the  snout  a  distance  equal  to  one-fourth  the  length 
of  the  snout.  The  diameter  of  the  orbit  is  nearly  equal  to  that  of  the  snout,  and  about  one- 
third  the  length  of  the  head.  The  width  of  the  interorbital  space  is  contained  twice  in  the 
longitudinal  diameter  of  the  orbit.  The  maxillary  is  broad  and  flattened  posteriorly,  is  con 
tained  about  8  times  in  the  length  of  the  body,  and  does  not  reach  to  the  perpendicular  bom 
the  anterior  margin  of  the  orbit.  The  insertion  of  the  dorsal  is  midway  between  the  tip  of  the 
snout  and  the  adipose  dorsal.  Its  height  is  greater  than  the  length  of  the  ventral,  which  is 
equal  to  the  greatest  height  of  the  body.  The  adipose  dorsal  is  over  the  middle  of  the  baseof 
the  anal,  its  length  two-fifths  of  the  diameter  of  the  orbit. 

The  distance  of  the  anal  from  the  snout  is  about  three-fourths  of  the  body's  length;  the

length  of  its  base  is  about  two-thirds  that  of  the  snout;  its  height  equal  to  the  diameter  of 
the  orbit.  Caudal  furcate.  Pectoral  Long  and  strong,  its  length  equal  to  the  distance  from 
the  tip  of  the  snout  to  the  posterior  margin  of  the  orbit,  and  about  twice  that  of  the  man 
dible.  The  ventral  is  inserted  under  the  middle  of  the  base  of  the  dorsal,  the  distance  from 
the  posterior  margin  of  the  orbit  equal  to  the  distance  of  the  latter  from  the  snout.  Color, 
brownish. 

Radial  formula:  D.  1,  8;  A.  1,  7;  V.  9  or  10. 

The  species  is  described  from  a  specimen  about  S  inches  in  length,  obtained  by  the 
steamer  Blake,  at  station  lii,  off  Barbadoes,  in  158  fathoms.

BENTHOSAURUS,  Goode  and  Bean. 

Benthosatinis,  Goode  and  Beax,  Bull.  Mas.  Comp.  Zool.,  xn.  No.  5,  165. 

Body  long,  somewhat  compressed,  tapering  into  a  slender,  elongate,  caudal  peduncle. 
Scales  cycloid,  of  moderate  size.  Head  slightly  depressed;  cleft  of  month  wide,  horizontal, 
the  lower  jaw  projecting  at  its  extremity  and  anteriorly  at  the  sides.  The  maxilla  is  long, 
not  stout,  dilated  posteriorly;  the  intermaxillary  very  long,  styliform,  tapering,  immovable. 
The  intermaxillary  and  mandible  with  bands  of  small  teeth,  of  uniform  size,  interrupted  at 
the  symphysis.  A  short  oblong  band  of  similar  teeth  on  each  side  of  the  vomer,  separated 
by  a  rather  wide  interspace.  Palate  and  tongue  smooth.  Bye  very  small,  inconspicuous.

BENTHOSAURUS  GRALLATOR,  Goode  and  Bean.     (Figure  73.) 
Bentho8aurus  grallator,  Goode  and  Bean,  Bull.  Mus.  Comp.  Zool.,xn,  No.  5, 168. 

Body  elongate,  somewhat  compressed,  depressed  slightly  forward,  tapering  behind  into 
a  long  slender  tail,  its  greatest  height  contained  71  times  in  its  standard  length,  and  equal- 
ing half  the  length  of  the  head,  its  greatest  width  one-third  the  length  of  the  head;  its 
height  at  the  origin  of  the  anal,  five-sixths  of  its  greatest  height.  Least  height  of  tail  half 
the  height  of  the  body  at  the  ventrals.     Length  of  caudal  peduncle  6i  times  its  least  height. 

Scales  very  thin,  cycloid,  leathery,  deciduous;  oval  in  form,  except  at  the  base  of  the 
dorsal  and  anal  fins,  where  they  become  more  elongate;  the  horizontal  diameter  of  a  scale 
in  the  lateral  line  equals  twice  the  diameter  of  the  eye.  The  lateral  line  is  straight,  above 
the  median  line  anteriorly,  becoming  median  on  the  caudal  peduncle,  the  tube-bearing  scales 
being  prominent,  and  about  55  in  number.  Between  the  dorsal  fin  and  the  lateral  line  are 
about  nine  rows  of  scales;  between  the  latter  and  the  anal  fin,  eight  or  nine  rows. 

Head  twice  as  long  as  the  greatest  height  of  the  body,  its  length  contained  a  little  less 
than  1  times  in  the  standard  body  length,  considerably  depressed,  scaleless  except  on  the 
vertex  and  the  preoperculum.     Operculum  (perhaps  accidentally)  denuded. 

The  snout  is  much  produced,  almost  equal  to  the  width  of  the  interorbital  space,  which 
is  convex.  The  maxilla  extends  far  behind  the  posterior  margin  of  the  eye,  its  length  equal- 
ing that  of  the  postorbital  part  of  the  head.  The  mandible  projects  beyond  the  upper  jaw 
to  a  distance  slightly  more  thau  the  diameter  of  the  orbit,  and  receives  the  snout  within  its 
extremity  when  the  jaws  are  closed.    The  teeth  have  been  fully  described  iu  the  generic

diagnosis.    The  mandible  has  a  scries  of  seven  large  pores  mi  its  lower  surface.    There  are 

several  similar  pores  under  the  eye.  The  nostrils  are  situated  about  midway  between  the 
eye  and  the  extremity  of  the  snout,  small,  slit  like,  the  posterior  about  twice  as  large  as  the 
interior  one  in  each  pair. 

The  dorsal  fin  contains  11  rays,  and  is  inserted  midway  between  the  tip  of  the  snout 
and  the  base  of  the  middle  caudal  rays.  The  tin  is  highest  in  front,  the  Length  of  the  rays 
diminishing  rapidly  posteriorly.    There  is  apparently  no  adipose  dorsal. 

The  anal  tin  contains  12  rays  and  is  similar  in  shape  to  the  dorsal,  the  anterior  rays 
being  the  longest,  and  about  equal  in  length  to  the  mandible;  its  distance  from  the  snout  is 
about  o  times  the  length  of  its  longest  ray. 

The  caudal  is  forked,  its  middle  rays  two-fifths  as  long  as  those  in  the  upper  caudal 
lobe;  the  lower  lobe  is  much  prolonged,  the  lower  ray  being  more  than  4  times  as  long  as 
the  middle  rays.  Its  extremity  is  broken  off  in  our  specimen,  but  apparently  it  must  have 
been  nearly  twice  as  long  as  the  stump  which  now  remains. 

The  pectoral  fin  is  normal,  composed  of  9  rays,  and  is  inserted  close  to  the  opercular 
flap;  its  length  is  slightly  greater  than  that  of  the  head  (although  mutilated),  extending 
beyond  the  origin  of  the  dorsal. 

The  ventral  is  composed  of  7  rays,  and  its  base  is  entirely  in  advance  of  the  perpendic- 
ular from  the  origin  of  the  dorsal;  the  inner  rays  reach  to  the  vent,  while  its  outer  ray  is 
enormously  prolonged,  extending  far  beyond  the  extremity  of  the  upper  caudal  lobe;  the 
length  of  the  prolonged  ray  is  fully  4  times  that  of  the  head.  The  two  ventrals  are  close 
together. 

Eadial  formula:  D.  11;  A.  12;  P.  9;  V.  7;  B.  11.     Scales,  9-53-8  or  9. 

Color  brown,  the  roof  of  the  mouth  and  inside  of  the  branchiostegal  flap  black,  as  well 
as  the  operculum  and  branchiostegal  membrane. 

A  single  specimen,  392  millimeters  (15i  inches)  long  to  the  tips  of  the  prolonged  ven- 
tral rays,  was  taken  by  the  Blake,  at  a  depth  of  1,830  fathoms,  at  station  CLSxrv,  in  lat. 
21°  33'  N.,  Ion.  84°  23'  W. 

A  second  example  of  the  same  fish,  and  of  nearly  the  same  size,  was  taken  by  the  steamer 
Albatross,  September  6, 1884,  in  lat,  39°  3'  13"  K  and  Ion.  70°  50' 45"  W.,  at  a  depth  of 
1,537  fathoms.  This  is  well  preserved,  and  throws  additional  light  on  the  external  charac- 
ters of  the-species;  the  fins,  especially,  are  more  nearly  perfect.  Measurements  of  the  two 
are  given  below.

fig.  4;  pi.  xv,  tigs.  4,  4a,  ib. 

This  species  does  not  appear  to  reach  a  large  size;  the  largest  of  the  many  examples, 
taken  by  the  Talisman  measuring  260  millimeters.  The  height  is  about  one-eighth  of  the 
total  length;  the  thickness  nearly  one-twelfth;  the  head  two- elevenths,  and  the  caudal

Bathypterois  dubivs,  of  Vaillant,  is  represented  in  his  collections  by  seventy  examples, 
among  which  he  recognizes  a  great  amount  of  individual  variation,  and  more  than  one 
species  may  be  included  under  this  name.     It  resembles  most  closely  B.  longipee. 

Examples  were  taken  off  the  coast  of  Morocco,  in  depths  ranging  from  834  to  1,590 

meters;  off  the  Canaries,  in  1,238  meters;  off  the  Soudan  coast,  in  932  to  1,232  meters;  on 

the  Arguin  Bank,  in  depths  of  1,113  to  1,195  meters,  and  at  the  Azores,  in  1,257  to  1,112 

meters. 

BATHYPTEROIS  QUADRIITLIS,  ci  ntheh.     (Figure  75.) 

Bathypterois  quadrifilis,  GfJNTHEK,  Ann.  and  Mag.  Nat.  Hist.,  1878,  u,  p.  184. — Challenger  Report,  xxu,  188, 
pi.  xxxm,  lig.  15. 

The  uppermost  and  lowermost  of  the  pectoral  rays  are  filiform,  the  former  bifid  tor 
more  than  two  thirds  of  its  length,  the  latter  simple.  Outer  ventral  rays  much  prolonged, 
not  dilated.     Dorsal  inserted  close  to  root  of  ventrals.     Adipose  tin  present. 

This  species  differs  somewhat  more  from  the  preceding  than  these  do  among  themselves. 
The  greatest  depth  of  the  body  is  one-seventh  of  the  total  length,  without  caudal,  the  length 
of  the  head  nearly  one-fifth.  The  head  is  remarkably  flat  above,  and  the  width  oftheinter- 
orbital  space  exceeds  the  length  of  the  snout.  The  eye  is  small,  but  larger  than  in  the  pre- 
ceding species,  about  one-third  of  the  length  of  the  snout,  and  one-fifth  or  one-sixth  of  the 
length  of  the  postorbital  portion  of  the  head.  The  dentition  and  branchial  apparatus  do 
not  offer  any  noteworthy  peculiarity. 

The  dorsal  tin  occupies  the  middle  between  the  extremity  of  the  upper  jaw  and  the  root 
of  the  caudal  fin.  A  narrow  adipose  tin  is  present  and  midway  between  the  dorsal  and  cau- 
dal. The  anal  tin  commences  immediately  behind  the  dorsal,  its  origin  being  equidistant 
from  the  roots  of  the  pectoral  and  caudal.    Caudal  tin  emarginate. 

The  principal  distinctive  feature  of  this  species  is  that  it  possesses  not  only  the  long 
detached  upper  pectoral  ray,  but  also  an  equally  long  lower  ray,  which,  however,  is  not 
removed  from  the  remainder  of  the  fin.  The  upper  ray  becomes  bifid  in  its  proximate  third, 
and  is  accompanied  by  an  extremely  short  rudimentary  second  ray;  it  scarcely  reaches  to 
the  caudal  tin  and  is  shorter  than  the  lowermost  ray,  which  may  reach  to  the  end  of  the 
caudal,  and  is  split  only  at  its  very  extremity. 

The  structure  of  the  ventral  tins  is  the  same  as  in  Bathypterois  longipes,  but  the  strong 
outer  rays  are  somewhat  curved  and  do  not  reach  the  end  of  the  anal. 

The  scales  are  cycloid,  as  in  the  other  species,  but  those  behind  the  basal  portion  of  the 
pectoral  tin  are  deeply  pectinated,  provided  with  from  5  to  10  long  aud  narrow  teeth,  of 
which  the  middle  ones  are  the  longest.     (Giinther.) 

Color  blackish  or  black;  pectoral  filaments  whitish.

The  types  of  this  specimen  were  obtained  by  the  Challenger  off  the  coast  of  Brazil;  two 
specimens,  one  from  station  120,  at  a  depth  of  770  fathoms,  one  from  station  121,  at  a  depth 
of  500  fathoms.

The  uppermost  pectoral  ray  is  the  strongest,  about  as  long  as  the  whole  tish,  bifid 
towards  its  extremity.  Outer  ventral  rays  much  prolonged,  strong,  but  not  dilated  at  the 
extremity.  Dorsal  fin  inserted  at  some  distance  behind  the  root  of  the  ventrals.  Adipose 
fin  present  or  absent. 

Similar  to  Bathypterois  longifilis,  from  which  it  differs  only  in  the  following  points:  Eye 
minute.  The  dorsal  tin  is  placed  farther  backwards,  its  origin  being  nearly  midway  between 
the  end  of  the  snout  and  the  root  of  the  caudal ;  consequently  the  root  of  the  ventral  is  some 
distance  in  advance  of  the  dorsal,  and  the  end  of  the  dorsal  is  vertically  opposite  to  the 
fifth  anal  ray.  One  specimen  possesses,  the  other  lacks,  adipose  tin.  Caudal  fin  deeply 
forked,  with  the  outer  ray  much  produced.  Of  the  two  branches  into  which  the  posterior 
third  of  the  long  pectoral  ray  is  split,  one  is  much  shorter  and  weaker  than  the  other.  The 
two  outer  ventral  rays  are  closely  adpressed  from  the  root  to  the  end,  and  much  stouter  and 
longer  than  the  other  rays;  they  are  articulated  to  the  end  and  without  the  soft  pads 
described  in  the  preceding  species.  These  fin  rays  extend  beyond  the  end  of  the  anal  fin.

fig.  IS. 

Body  elongate,  cylindrical;  tail  compressed  behind;  head  depressed.  The  deptb  of  the 
trunk  diminishes  l>nt  little  backwards,  and  is  contained  L3J  times  in  the  total  length,  with- 
out  caudal;  the  length  of  the  head  is  one-sixth  of  the  total.  Head  broad,  much  broader 
than  deep,  its  greatest  depth  being  two-thirds  of  its  length.  Snout  broad,  much  depressed, 
with  obtusely  rounded  anterior  profile;  cleft  of  the  mouth  verj  wide,  the  maxillary  moder- 
ately dilated  behind  and  extending  beyond  the  middle  of  the  length  of  the  head.  Man- 
dible projecting  beyond  the  upper  jaw,  broad,  but  owing  to  the  depressed  form  of  the  snout 
its  upper  surface  is  nearly  entirely  at  the  lower  side  of  the  snout.  Infraorbital  chain  of 
bones  very  narrow,  wedged  in  between  the  transparent  lamina  and  the  maxillary,  with  four 
\er\  distinct  apertures  leading  into  the  mucous  duet.  The  upper  surface  of  the  head,  includ- 
ing the  snout,  is  wholly  covered  by  the  two  cornea  like  laminae  of  the  luminous  apparatus. 
They  an'  closely  attached  to  each  other  along  the  median  line,  each  being  divided  by  a 
shallow  transverse  ridge  into  a  larger  anterior  and  a  smaller  posterior  portion.  The  ridge 
turns  forward  near  and  parallel  to  the  median  line,  and  marks  the  course  of  a  superficial 
mucous  duet. 

The  gill  laminae  are  well  developed  and  the  gill  rakers  long,  needle-shaped,  closely  set, 
about  22  in  number  on  the  outer  branchial  arch. 

The  vent  is  nearly  twice  as  distant  from  the  root  of  the  caudal  fin  as  from  the  end  of 
the  snout,  and  rather  more  than  the  length  of  the  head  from  the  gill  opening;  it  is  placed 
between  the  ventral  fins. 

The  dorsal  fin  commences  immediately  behind  the  vertical  from  the  vent;  it  is  short, 
but  its  longest  rays  are  twice  as  high  as  the  body.  Origin  of  the  anal  midway  between  the 
vent  and  the  root  of  the  caudal,  composed  of  rays  which  are  more  slender  and  shorter  than 
those  of  the  dorsal.  Caudal  fin  narrow,  subtruncated,  more  than  half  as  long  as  the  head. 
Pectorals  rather  feeble,  lateral,  as  long  as  the  caudal,  and  extending  to  the  ventrals.  Veu- 
trals  are  composed  of  stronger  rays,  horizontally  placed  and  somewhat  distant  from  each 
other,  as  is  frequently  found  in  fishes  habitually  moving  on  the  bottom ;  they  slightly  exceed 
the  pectorals  in  length. 

The  scales  are  large,  thin,  deciduous,  forming  only  six  longitudinal  series  on  each  side 
of  the  trunk.  Lateral  line  faintly  indicated  along  the  middle  of  the  body;  the  muciferous 
channels  on  the  head  are  also  narrow,  with  small  apertures.  Brown,  fins  colorless.  Buccal 
and  branchial  cavities  and  lower  side  of  head  black.     (jQUnther.)

The  height  of  the  body  is  a  little  less  than  one-fourth  of  the  total  length;  length  of 
head  a  little  less  than  one  third.  Eye  minute;  contained  about  23  times  in  length  of  head, 
and  aboul  8  times  in  that  of  snout ;  inserted  midway  between  the  margin  ofthejawand  the 
dorsal  profile,  distant  from  the  former  a  space  contained  about  2  J,  times  in  the  length  of  the 
snout.  The  maxillary  reaches  very  far  back,  extending  to  a  point  behind  the  orbit  equal  to 
1A  times  the  length  of  the  snout.  The  origin  of  the  dorsal  is  directly  above  that  of  the  anal, 
which  is  inserted  a  short  distance  behind  the  vent;  distance  from  the  snout  equal  to  more 
than  I  times  the  length  of  its  own  base,  and  the  distance  of  its  termination  from  the  root 
of  the  upper  rays  of  the  caudal  equal  to  its  own  greatest  height.  The  anal  fin  is  similar  in

CKTOMIMUS  STORERI,  Goobb  and  Bean,  n.  8.     (Figure  79.) 


The  height  of  the  body  is  a  little  more  than  one-fourth  of  the  total  length:  the  length 
of  the  head  is  contained  3:\  in  that  of  the  body.  Diameter  of  the  eye  continued  about  18 
times  in  the  length  of  the  head,  and  about  7  times  in  that  of  the  snout,  the  eye  being  inserted 
nearer  to  the  dorsal  profile  than  to  the  jaw,  its  position  in  the  vertical  being  twice  as  far 
from  the  line  of  the  upper  jaw  as  from  the  dorsal  line;  it  is  nearly  in  the  line  of  the  vertical 
erected  from  the  middle  of  the  upper  jaw  to  the  right  angles  of  its  edge.  The  lower  jaw  is 
strongly  curved,  and  projects  far  beyond  the  upper.  The  origin  of  the  dorsal  fin  is  a  little 
in  advance  of  that  of  the  anal,  which  is  inserted  at  a  distance  from  the  vent  equal  to  3  or  4 
times  the  diameter  of  the  eye.  The  dorsal  fin  is  longer  than  the  anal,  the  termination  of 
the  latter  being  under  the  fifth  ray  from  the  end  of  the  dorsal.  They  are  aboul  equal  in  height, 
and  the  direction  of  the  rays  when  erected  is  backward  and  at  an  acute  angle  with  the  axis 
of  the  body.  The  longest  rays  are  contained  about  2.V  times  in  the  length  of  the  head. 
Pectoral  tin  is  inserted  very  far  down,  the  lower  portion  of  its  peduncle  almost  on  the 
abdominal  line;  the  finis  lanceolate,  and.  although  mutilated,  is  believed  to  have  been  about 
half  as  long  as  the  head.  The  lateral  line  sweeps  in  a  sinuous  curve  from  a  point  above  the 
upper  angle  of  the  gill  opening  to  a  point  somewhat  in  advance  of  the  insertion  of  the 
dorsal,  and  thence  in  a  straight  line  to  the  base  of  the  caudal.  A  line  of  mucous  pores  on 
either  side  of  the  median  dorsal  line  in  advance  of  the  dorsal  tin.

A  single  specimen  (Xo.  35G34,  U.  S.  X.  M.),  4§  inches  in  length,  was  taken  by  the  Fish 
Commission  steamer  Albatross  at  station  2222,  on  September  (i.  1884,  in  39°  03  15"  X.  hit.. 
70"  50'  45"  W.  Ion.,  at  a  depth  of  1,535  fathoms. 

This  species  is  provisionally  described  from  a  careful  drawing  made  by  Mrs.  Eilde- 
brandt,  December  11,  1SS4,  under  the  criticism  of  Dr.  Bean,  the  type  specimen  being  inac- 
cessible at  the  time  this  study  is  made. 


70  DEEP-SEA    FISHES    OF   THE    ATLANTIC    BASIN. 

This  species  is  named  in  honor  of  the  late  Dr.  David  Humphreys  Storer,  in  token  of 
our  appreciation  of  the  distinguished  services  of  this  pioneer  of  American  ichthyology.

Myciapliidu',  Gill,  MS. 

Body  oblong  or  moderately  elongate,  compressed  (except  in  Scopelosaurus),  covered 
with  scales,  which  are  usually  cycloid.  Mouth  wide,  the  entire  margin  of  the  upper  jaw 
formed  by  the  long  and  slender  preuiaxillaries,  closely  adherent  to  which  are  the  slender 
maxillaries.  Teeth  various,  mostly  villiform,  and  in  bauds  iu  the  jaw;  also  pterygoids, 
palatines,  and  tongue;  also  on  vomer  in  adults.  No  barbels.  Gill  membranes  separate, 
free.  Branchiostegals,  8-10.  Pseudobranchiae  well  developed.  Gill  rakers  long  and 
slender.  Lateral  line  present,  the  scales  prominent  and  often  enlarged.  Cheeks  and 
opercles  scaly.  Adipose  fin  present.  Dorsal  fin  short,  median,  of  soft  rays.  Pectorals 
and  ventrals  present.  Anal  fin  moderate.  Caudal  forked.  Air  bladder  small.  Intestinal 
canal  short.    Sides  scaly,  with  phosphorescent  spots. 

For  convenience  of  study  and  comparison,  it  would  seem  somewhat  desirable  that  the 
forms  now  usually  grouped  under  the  great  polymorphous  genus  Scopelus,  should  be  divided 
into  minor  groups.  We  have,  therefore,  proposed  the  provisional  plan  formulated  iu  the 
accompanying  key.    Some  of  the  groups  are  probably  of  subgeneric  value. 

Siuce  the  completion  of  our  study  of  this  family,  two  important  papers  have  appeared: 
the  first  by  Dr.  Fed.  Raffaele,  published  in  the  "Mittheilungen"  of  the  Zoological  Station 
at  Naples  in  1889,  and  secondly,  Dr.  Liitken's  masterly  and  exhaustive  paper  on  the  Scope- 
lids  of  the  Zoological  Museum  of  the  University  of  Copenhagen,  forming  part  2  of  "Spolia 
Atlautica,"  printed  in  the  Memoirs  of  the  Eoyal  Academy  of  Sciences  and  Letters  of  Den- 
mark, sixth  series,  Vol.  vn,  part  (i,  Copenhagen,  1892. 

The  first  of  these  papers  announced  an  important  new  system  of  discriminating  between 
the  species  of  fishes  formerly  grouped  in  the  genus  Scopelus,  based  upon  the  arrangement 
of  the  luminous  spots,  which  were  classified  by  the  author  in  eight  groups. 

At  the  time  when  Dr.  liaffaele's  paper  was  brought  to  our  attention,  our  book  was  being 
put  in  type,  so  that,  beyond  reference  to  it  in  the  synonymy,  it  was  impossible  to  utilize  the 
work  of  the  author,  for  it  became  evident  that  if  his  plan  were  adopted  it  would  necessitate 
an  entire  revision  of  our  plan  of  classification,  and  while  it  seemed  to  be  full  of  suggestions 
we  were  not  yet  satisfied  as  to  the  extent  of  the  usefulness  of  the  proposed  new  plan. 

The  publication  of  Liitken's  work  lias,  however,  rendered  it  necessary  to  completely 
revise  our  opinions  upon  the  relations  of  the  species.  A  review  of  the  group  in  the  light 
of  Liitken's  conclusions  convinced  us  that  the  arrangement  of  the  luminous  spots  is  of  the 
greatest  value  in  the  classification  of  these  fishes.

72  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

Two  specimens  (No.  23369,  U.  S.  X.  ft£ ;  Xo.  272,  Gloucester  Donations),  90  and  G3  milli- 
meters, were  taken  on  tlie  Grand  Bank  by  tlie  schooner  Lizzie.  Individual,  90  millimeters 
in  length,  is  Xo.  43787,  U.  S.  X.  M. ;  Xo.  284,  of  the  Gloucester  Donations.  Another  (Xo. 
23756,  TJ.  S.  X.  M. ;  No.  588,  Gloucester  Donations),  95  millimeters  in  length,  washed  aboard 
the  schooner  Conductor  on  the  Grand  Bank.  A  specimen  (Xo.  934,  Gloucester  Donations), 
100  millimeters  in  length,  was  taken  by  schooner  Marguerite,  off  Banquero.  Still  another 
specimen  (Xo.  24646,  U.  S.  X.  M.;  Xo.  607,  Gloucester  Donations),  90  millimeters  in  length, 
washed  aboard  the  schooner  Gatherer  on  the  Grand  Bank.  An  individual  (Xo.  43781,  U.  S.  X. 
M. ;  Xo.283,  Gloucester  Donations),  87  millimeters  in  length,  with  caudal  somewhat  imperfect, 
was  obtained  January  30,  1879,  in  about  44°  30'  N.  lat.,  54°  35'  W.  Ion.  It  washed  aboard 
in  rough  weather.  One  (Xo.  608,  Gloucester  Donations),  83  millimeters  in  length,  washed 
aboard  the  schooner  Plymouth  Rock  on  the  Grand  Bank  during  a  storm.  Another  (Xo. 
2404S,  U.  S.  X.  M.;  Xo.  604,  Gloucester  Donations;,  also  washed  aboard  the  schooner  Mary 
F.  Chisholm  on  southern  edge  of  the  Grand  Bank.  A  specimen  (Xo.  43783,  U.  S.  X".  M. ;  Xo. 
573,  Gloucester  Donations),  three  specimens  (Xo.  43788,  U.  S.  X.  M. ;  No.  867,  Gloucester 
Donations),  three  specimens  (Xo.  29982,  IT.  S.  X.  M.),  and  specimens  (Xo.  43784,  IT.  S.  X 
M. ;  Xo.  281,  Gloucester  Donations)  were,  also  obtained  by  the  Gloucester  fisherman. 

The  Fish  HawTc  secured  three  specimens  (Xo.  2S999,  TT.  S.  X.  M.)  from  station  1044,  in 
38°  37'  X.  lat,,  73°  12'  W.  Ion.,  at  a  depth  of  224  fathoms;  and  the  Albatross  captured 
several  specimens  (Xo.  43781!,  0".  S.  X.  M.)  at  the  surface  at  station  2549,  in  39°  51'  30"  X. 
lat.,  70°  17'  W.  Ion.,  a  depth  of  571  fathoms,  and  specimens  (Xo.  35696,  O.  S.  X.  M.)  from 
station  2262,  in  39  ^  54'  45"  X.  lat.,  69°  29'  45"  W.  Ion.,  at  a  depth  of  250  fathoms. 

This  species  is  evidently  the  J/,  punctatum  of  Rafinesque,  as  well  as  of  Bonaparte. 
We  have  identified  it  with  a  number  of  specimens  labeled  "Scopelus  Ganinianus,"  obtained 
at  Messina  and  presented  by  the  Royal  Zoological  Museum  at  Florence  (Xo.  40057,  U.S. 
X.  M.),  and  also  with  the  figure  and  description  of  Bonaparte  and  Rafinesque.  Though 
Rafinesque's  figure  does  not  fully  agree  with  the  description,  which  is  manifestly  careless, 
it  has  the  posterolateral  photophores  in  front  of  the  dorsal,  as  in  all  our  specimens. 

We  arc  unable  to  determine  exactly  what  form  is  that  discussed  by  Lutken  (p.  251), 
under  the  name  Scopelus  Caninianus,  Cocco,  for  it  has  the  posterolateral  photophore  much 
farther  back  in  relation  to  the  termination  of  the  second  dorsal  and  anal  fin  than  has  our 
M. punctatum,  and  is  in  this  respect  more  closely  allied  to  Liitken's  Scopelus  ajfini.s  (p.  252). 

MYCTOPIIUM  AFFINE,  (Lctkkn!,  G k  and  Bean. 

Scopelus  axJiiiis,  Li'"TKEN,  Spolia  Atlantica,  n,  1892;  32,  Fig.  L0. 

A  species  of  Myctophum  closely  resembling  M. punctatum,  but  having  the  posterolateral 
photophore  farther  back,  under  the  soft  dorsal  and  not  far  in  advance  of  the  vertical  from 
the  last  ray  of  the  anal,  over  which  occurs  the  break  in  the  series  ofsuperanal  photophores, 
the  number  of  which  is  7-10  +  4-6.     Radial  formula: — (!):  L.  lat.  37. 

Liitken  examined  a  considerable  number  of  specimens  of  this  species,  presumably  all 
taken  at  the  surface,  between  38°  40'  X.  lat.,  63°  W.  Ion.,  and  39°  54'  S.  lat.,  41°  30'  E.  Ion. 

MYCTOPHTOI  OPALINUM,  Goode  and  Beau,  n.  s.     (Figure  81.) 

Height  of  body  contained  4§  times  in  total  (without  caudal);  head  4  \.  Least  height  of 
tail  is  two-fifths  of  height  of  body.  Snout  very  short,  declivous,  with  a  well-developed 
median  keel,  its  length  about  one-third  of  diameter  of  eye.  Eye  large,  about  2|  in  the  head- 
Intermaxillary  reaches  nearly  to  angle  of  preoperculum  and  is  broadly  expanded  at  its

thai  of  head.     Caudal  is  rather  small  and  moderately  lurked. 

Mediolateral  photophores  three,  in  straight,  obliquely  ascending  line;  anterolateral  one; 
posterolateral  one,  under  soft  dorsal  and  over  and  slightly  in  advance  of  break  in  row  of 
superanals,  which  is  above  root  of  last  ray  of  anal.     Number  of  superanals  s+6. 

In  most  of  tin'  specimens  of  .1/.  opalinum  examined ,  the  6 or  8  scales  on  the  top  of  the 
caudal  peduncle,  immediately  in  front  of  the  caudal  tin.  are  luminous. 

MYCTOPHUM  PHENGODES,  (LttTKKN),  Goodi  and  Bean. 

Scopelus phengodea,  LOtken,  Spolia  Atlanta ea,  n,  1892,  253,  Fig.  11. 

A  species  resembling  in  general  appearance  our  Myctophum  punctatum,  from  which  it 
is  distinguished  by  having  a  long,  falcate  pectoral,  the  tip  of  which  extends  almost  to  the 
vertical  from  the  vent,  and  is  uearer  to  the  row  of  mediolateral  photophores  than  to  the 
anterolateral.  This  form  has.  asin  .1/.  punctatum,  the  posterolateral  considerably  in  advance 
of  the  soft  dorsal,  and  has  the  precaudal  photophores  much  farther  apart  (a  character  upon 
which  some  stress  is  laid  by  Liitkeu,  but  which  seems  to  us  of  le  ss  importance  than  the 
position  of  the  posterolateral  photophore).     Number  of  superanals,  G-7  +  7-9. 

Radial  formula:  D.  12;  A.  21;  L.  hit.  38. 

Liitkeu  had  it  from  the  Atlantic,  south  of  the  equator,  presumably  from  surface.

This  species  was  first  described  from  the  Mediterranean  about  Nice,  but  appears  to  be 
rare.  The  British  Museum  had  specimens  from  the  eastern  Atlantic.  The  Albatross 
obtained  a  specimen  (No.  43772,  U.  S.  N.  M.)  upon  the  surface,  at  7  p.  m.,  from  station  2727, 
in  36°  35'  N.  lat.,  74°  03'  30"  W.  Ion.,  and  also  a  very  line  specimen  (No.  43773,  U.  S.  N.  M.) 
from  station  2724,  in 36° 47'  N.  lat.,  73'  25'  W.  Ion.,  at  a  depth  of  1,041  fathoms. 

Liitkeu  had  a  number  of  specimens  of  M.  Humboldtii  {op.  <it..  p.  254,  tic;.  2)  from  the 
following  localities:  X.  lat.  34°  20',  W.  Ion.,  18°  30';  N.  lat,  12°  12',  W.  Ion.  28°  48';  S.  lat.

Liitken  unites  M.  lumps  with  M.  Humboldtii,  but  since  the  latter  has  been  as  yet  found 
only  in  the  northeastern  Pacific,  we  prefer  to  hold  them  apart  until  specimens  from  the  two 
oceans  have  been  studied  side  by  side.     The  scales  in  lateral  line  are  said  to  number  37-9.

Scoj)el us  gracilis,  Li  tken,  Spolia  Atlantica.  II,  1892,255,  fig.  13. 

A  species  closely  allied  to  M.  Hnmboldii.  haying  mediolateral  photopliores  two,  antero- 
lateral two,  posterolateral  one,  over  the  break  in  the  anal  series,  which  is  much  in  front  of 
the  soft  dorsal  and  over  the  middle  of  the  anal  flu,  the  number  of  anal  photophores  being 
5-7+11-14.  The  pectoral  is  moderate,  not  passing  the  second  anterolateral  photophore. 
The  caudal  photophores  are  close  together  as  in  M . punctatum. 

Eadial  formula:  D.  12;  A.  19;  L.  lat.  41. 

Lutken  had  several  specimens,  presumably  from  the  surface,  taken  in  the  following 
localities:  M.  lat.  22°,  W.  Ion.  34°  30';  N.  lat.  22°  12',  W.  Ion.  48°;  S.  lat.  35°  36',  E.  Ion.

The  height  of  the  body  is  contained  4  times  in  the  total  length  (without  caudal) ;  the 
head  3J.  The  snout  is  obtuse,  conical,  the  upper  and  lower  profiles  nearly  equally  curved. 
The  eye  is  large,  its  diameter  a  little  less  than  half  the  length  of  the  head.  The  dorsal  is 
postmedian,  nearly  midway  between  the  snout  and  the  root  of  the  caudal,  and  behind  the 
base  of  the  ventral.  The  pectoral  extends  nearly  to  the  end  of  the  ventral.  The  photo- 
phores are  arranged  as  follows :  Mediolaterals,  2;  anterolaterals,  2;  posterolaterals,  2,  over 
the  break  in  the  superanal  series,  which  is  not  far  in  advance  of  the  vertical  connecting 
the  base  of  the  last  anal  rays  with  that  of  the  soft  dorsal.  The  two  anterolaterals  far  apart, 
the  caudals  near  together,  the  last  far  below  the  end  of  the  lateral  line.  Number  of  super- 
anals,  5-0+0-7. 

Eadial  formula:  I).  12-13;  A.  17-18;  L.  lat.  39-10. 

Gunther  gives  Norway  and  Greenland  as  the  range  of  this  species,  but  cites  no  au- 
thority for  this,  and  appears  to  have  examined  only  Mediterranean  material.  The  species 
has  been  observed  at  Nice  and  Messina,  whence  the  National  Museum  has  specimens  (Cat. 
No.  40063)  received  from  the  I  loyal  Museum  of  Florence.  Lutken  had  a  specimen,  40  milli- 
meters long,  from  N.  lat.  34°  40',  W.  Ion.  24°  20'.  His  type,  as  well  as  the  Messina  speci- 
men examined  by  us,  has  a  luminous  plate  on  the  top  of  the  caudal  peduncle. 

MYCTOPHUM   REINHARDTII  (Lutken). 
Scopelus  Reinhardtii,  Lutken,  spuliu  Atlantica,  n.  1892,  257,  fig.  16. 

A  species  of  Myctophum  resembling  M.  Benoiti  in  general  appearance,  but  having  the 
anterolateral  photophores  much  closer  together  than  in  that  species,  the  foremost  being,  as  in 
M.  Benoiti,  almost  directly  above  the  root  of  the  ventral  fin.  The  precaudals  are  well  sep- 
arated, the  posterior  one  considerably  above  the  anterior,  and  touching  the  extremity  of 
the  lateral  line.  Pectoral  long,  falcate,  extending  quite  to  the  lower  mediolateral  photo- 
phore, and  almost  to  the  vertical  from  the  vent.    The  number  of  the  superanals  is  4-7+7-8. 

Eadial  formula:  D.  11;  A.  10. 

The  two  examples  studied  by  Lutken  were  obtained  from  N.  lat.  34°  22',  W.  Ion.  18° 
10',  and  N.  lat.  5°  31',  W.  Ion.  23°  15'.  One  of  these  had  a  luminous  plate  on  the  top  of 
the  caudal  peduncle,  the  other  a  similar  plate  below. 

MYCTOPHUM  REMIGER,  Goode  and  Beax,  n.  s.     (Figure  84.) 

Depth  of  body  is  one-fourth  of  total  length.  Length  of  head  3|  times  in  total  length. 
Least  height  of  tail  about  two-thirds  of  its  greatest  height.  Snout  very  short,  the  upper 
and  lower  profile  of  the  head  being  similar;  its  length  a  little  less  than  one-half  diameter

of  eye.  Eye  large,  nearly  two-fifths  lengtb  of  the  head.  Intermaxillary  reaches  as  far 
back  as  maxillary,  nearly  to  angle  of  the  preoperculum.  Maxillary  expanded  posteriorly 
and  concealed  under  large  scales  of  cheek.  Space  between  eye  and  hinder  edge  of  pre- 
operculum one-third  diameter  of  the  eye.  Origin  of  dorsal  nearer  tip  of  snout  than  rout  of 
caudal,  being  over  eleventh  scale  of  lateral  line,  and  nearly  over  origin  of  ventral.  Base  ol 
dorsal  two-thirds  as  long  as  head,  and  length  of  longest  ray  equals  length  of  head  without 
snout.  Ventral  does  not  quite  reach  rent.  Pectoral  as  long  as  head,  and  reaches  to  above 
anal  origin.  Anal  origin  nearly  under  end  of  dorsal  base.  The  length  of  anal  base  is  a 
little  greater  than  that  of  head.     Caudal  rather  small  and  forked. 

Posterolaterals,  2,  over  break  in  superanal  series  and  far  apart,  the  anterior  one,  nearly 
over  middle  of  anal  tin,  the  posterior  one  about  one  scale  in  advance  of  the  vertical  from 
the  root  of  the  soft  dorsal.  Anterolaterals  widely  separated,  the  first  obliquely  in  advance 
of  and  above  the  second,  and  touching  or  upou  the  lateral  line;  the  second  far  behind  the 
root  of  the  ventral  and  over  the  interval  between  the  first  and  second  postcentral  photo- 
phores.     Superanals  7  +  G.     Radial  formula:     D.  12;  A. 21-22;  L.lat. 38-42. 

This  species  is  closely  related  to,  if  not  identical  with,  .1/.  Rygomii  of  Liitken.  If  they 
prove  to  be  identical,  Liitken's  name  has  priority. 

This  species  is  described  from  eight  specimens  (No.  4.3702,  U.  S.  N.  M.)  obtained  at  the 
surface  by  the  steamer  Albatross  at  station  257.'!,  in  40°  34'  IS"  N.  lat.,  04°  09'  W.  Ion. 
They  were  attracted  by  the  electric  light.  The  largest  example  is  75,  and  the  smallest  56 
millimeters  in  length.  Six  specimens  (No.  3S193,  U.  S.  N.  M.)  were  also  taken  by  the  Alba- 
tross at  the  surface  at  7  p.  m.  at  station  2727,  in  36°  35'  N.  lat.,  74°  03'  30"  W.  Ion.;  speci-

A  species  closely  related  to  3L  remiger,  (loode  and  Bean,  if  not  identical  with  it,  the 
arrangement  of  the  photophores  being  very  nearly  the  same,  except  that  the  anterolaterals' 
are  somewdiat  more  widely  separated  vertically,  the  anterior  and  upper  one  being  above  the 
origin  of  the  ventral,  the  posterior  and  lower  one  above  the  second  post- ventral  photophore. 
The  pectoral,  though  long  and  falcate,  does  not  extend  so  far  back,  not  closelyr  approaching 
either  the  most  advanced  of  the  mediolaterals  or  the  vertical  from  the  vent.  The  postero- 
laterals are  much  closer  together  than  in  M.  remiger,  and  the  precaudals  farther  apart,  the 
posterior  one  being  relatively  higher  and  placed  nearly  upon  the  extremity  of  the  lateral 
line,  instead  of  being  quite  below  it,  as  in  M.  remiger.    Number  of  superanals  7+6  or  5-6+6.

BENTHOSEMA,   Goode  and    Bean. 

This  form  differs  from  the  typical  Myctophum  by  the  fact  that  the  dorsal  is  considerably 
shorter  than  tha  anal,  but  overlaps  it,  reaching  to  the  vertical  from  the  middle.  It  has  the 
body  elongate,  the  caudal  peduncle  somewhat  stout,  the  eyes  large,  the  snout  very  short, 
with  declivous  upper  profile;  maxillaries  considerably  dilated  behind:  scales  of  the  lateral

anterolaterals,     (fjiyftos,  the  ocean  depth:  -',,"/,  a  constellation  of  stars.) 

To  this  genus  apparently  belong,  in  addition  to  the  type  species,  B.  Mulleri  (  =  B.  gla- 
cialis,  Bernhardt,  as  identified  by  Liitken),  the  two  species  described  by  Liitken  now  under 
the  names  Scopelus  arcticus  and  Scopelus  Golletti.  The  species  described  by  us  under  the 
name  Benthosema  Giintheri  is  now  referred  to  our  modified  genus  Lampanyctus.

This  species,  until  recently  known  only  from  the  roast  of  Greenland  and  the  northern 
shores  of  Norway,  has  been  frequently  taken  since  1881  by  the  IT.  S.  Fish  Commission  off 
the  southern  shores  of  New  England,  and  also  by  the  Blake  at  numerous  stations  mentioned 
below.  Collett  believes  it  to  have  been  obtained  by  the  Norwegian  North  Atlantic  Expedi- 
tion in  a  (hedge  which  was  worked  at  a  depth  of  1,110  fathoms.  The  depth  of  the  west 
Atlantic  was  from  300  to  600  fathoms,  and  it  was  found  as  tar  south  as  the  coast  of  South 
Carolina.  The  specimens  are  usually  in  a  very  suit  ami  battered  condition,  indicating  that 
they  have  been  obtained  at  a  considerable  depth;  and  ( 'ollett  found  in  the  stomach  of  one  of 
those  examined  by  him  an  ostracod  (Concosciaborealis),  which  has  never  been  found  nearer 
the  surface  than  at  a  depth  of  300  fathoms,  (i  anther  and  Collett  believe  it  to  be  truly 
batbybial,  and  the  testimony  of  the  Fish  Commission  explorers  tends  iu  the  same  direction 
with  regard  to  these  as  to  the  majority  of  the  other  species  of  the  family. 

Specimens  of  this  species  were  obtained  by  the  Blake  from  the  following  localities:

78  DEEP-SEA   FISHES   OF   THE   ATLANTIC    BASIN. 

BENTHOSEMA  ARCTICUM,  (Lutken),  Goode  aud  Bean. 

Scopelus  articus,  Lutken,  Spolia  Atlantica,  n,  1892,  249,  Fig.  6. 

A  species  apparently  more  closely  related  to  B.  Miilleri  than  to  any  other  form,  but 
having  no  posterolateral  photophore  and  uo  break  in  the  series  of  superanals,  the  number 
of  which  is  fifteen  or  sixteen.  It  has  two  mediolaterals  in  subhorizontal  line,  continuous 
with  the  two  anterolaterals.  It  is  a  much  shorter-bodied  form  than  B.  glacialis,  and  has  a 
much  shorter  and  higher  first  dorsal.  Liitken's  figure  shows  only  one  opercular  photophore, 
instead  of  two,  which  are  customary.    Eadial  formula:  D.  9;  A.  17;  P.  14;  V.  8. 

Liitken's  types  were  four  specimens  obtained  from  Greenland  and  one  from  Davis's 
Strait.  Two  of  them  have  a  large  supracaudal  luminous  plate,  and  three  others  small 
infracaudal  luminous  plates. 

BENTHOSEMA  COLLETTI,  (Lutken),  Goode  and  Bean. 

Scopelus  Colletti,  Lutken,  Spolia  Atlantica,  n,  1892,  249,  Fig.  7. 

A  species  having  the  photophores  arranged  somewhat  as  in  B.  arcticiim,  but  with  the 
two  mediolaterals  in  a  subvertical  hue  continuous  with  the  last  of  the  ventral  photophores, 
instead  of  approximately  with  the  anterolaterals.  There  is  no  posterolateral  photophore. 
The  superanals  are  in  a  continuous  row,  10-17  in  number.  Head  somewhat  blunt;  pectoral 
short,  as  in  B.  arcticum,  reaching  about  to  the  vertical  from  the  origin  of  the  first  dorsal. 

Eadial  formula:  D.15;  A.  21;  L.  lat,  38. 

This  species  is  described  from  a  single  specimen  in  the  Museum  at  Christiania,  obtained 
from  the  Pacific,  GUO  miles  west  of  Cape  Horn.

anale,  1826,  in,  466.— Raffaele,  Mitt.  ZoGl.  Stat.  Naples,  i\,  184,  PL  vn,  Fig.  10. 

Height  of  body  one-fifth  of  total  length;  length  of  head  two-sevenths.  Least  depth 
of  tail  slightly  greater  than  half  the  height  of  body.  Head  three-fifths  as  high  as  long. 
Bye  moderate,  contained  5  times  in  length  of  head.    Posterior  margin  of  preoperculum 

obliquely  descending  backwards  as  in  L.  gemellarii,  but  in  an  even  sharper  angle,  to  allow 
for  the  expansion  of  the  enormous  reptile  like  mouth.  The  mouth  is  slightly  oblique, 
curved;  the  maxillary  reaches  nearly  to  the  angle  of  the  preoperculum,  and  is  but  slightly 
dilated  behind.  Origin  of  the  dorsal  fin  in  advance  of  a  point  midway  between  the  ex- 
tremity of  the  snout  and  the  root  of  the  caudal  by  a  distance  equal  to  space  from  lobe  of 
snout  to  posterior  margin  of  orbit  and  placed  farther  back  than  usual  in  relation  to  the 
ventrals,  its  origin  being  above  the  axil  of  the  latter.  Caudal  large,  furcate.  Pectoral 
lanceolate,  long,  and  strong,  its  tip  extending  to  the  vertical  from  the  middle  of  the 
dorsal.     Scales  smooth,  those  of  the  lateral  line  very  slightly  enlarged. 

Mediolateral  photophores,  2;  posterolaterals,  2,  one  above  the  other,  or  nearly  so.

A  single  specimen  (No.  43777,  U.  S.  N.  M.),  52  millimeters  in  length,  was  obtained  by 
the  Gloucester  fleet,  it  being  No.  100  of  the  Gloucester  series. 

The  species  is  dedicated  to  the  author  of  the  Catalogue  of  the  Fishes  of  the  British 
Museum  and  the  Fishes  of  the  Challenger,  monumental  works,  which  are  the  foundations  of 
ichthyological  work  in  the  last  half  of  the  nineteenth  century. 

LAMPANYCTUS  WARMINGII,  (Lutkkn),  Goode  and  Bean. 

Scopelus  (Xotoscopelus)  Warmingii,  Lutkex,  Spolia  Atlautica,  n,  1892,  259,  fig.  19. 

A  species  closely  allied  to  Lampanyctus  Giintheri,hamug  long  pectorals,  and  precaudals 
3+1,  the  last  at  end  of  lateral  line.     Superanals,  7  +  .">.     Radial  formula:  D.  12;  A.  13. 

This  species  is  distinguished  from  L.  Giinthcri  by  having  one  more  precaudal  photo- 
phores  in  the  first  group  and  by  having  a  shorter  pectoral,  which  docs  not  reach  to  the 
origin  of  the  anal,  while,  in  L.  Oiintheri  it  extends  far  behind  the  eud  of  the  pectoral  and 
nearly  to  the  middle  of  the  base  of  the  anal.  The  posterolaterals,  one  or  two  in  number, 
are  continuous  in  the  gently  curved  series  of  the  anterior  half  of  the  broken  superanal  series. 

LAMPANYCTUS  GEMMIFEE,  Goode  and  Bean,  u.  s.     (Figure  88).

depth  of  tail  two-thirds  height  of  body.  Eye  large,  nearly  one-fourth  length  of  head.  Dis- 
tance between  posterior  margin  of  orbit  and  preopercular  edge  equals  diameter  of  eye. 
Snoutobtuse,  very  short,  its  length  less  than  half  diameter  ol  eye.  Maxillary  scarcely  dilated 
behind.  Origin  of  dorsal  midway  between  tip  of  snout  and  dorsal  mirror.  Base  of  dorsal 
equal  to  length  of  postorbital  part  of  head,  and  about  equal  to  longest  dorsal  ray.  Ventral 
origin  slightly  in  advance  of  dorsal  origin.  Pectoral  reaches  slightly  beyond  origin  of  anal. 
Scales  smooth,  those  of  the  lateral  line  scarcely  larger  than  others.  Mediolateral  photo- 
phores,  2;  posterolaterals,  2,  the  latter  one  above  the  other,  or  nearly  so.  Precaudals,  4-5 
in  nearly  horizontal  though  curved  row,  the  last  far  below  the  end  of  the  lateral  line. 
Anterolaterals,  3,  in  nearly  continuous  line  with  lowest  prepectoral  and  mediolaterals.  Num- 
ber of  superanals  7-8.  The  pearly  mirror  upon  the  upper  edge  of  the  caudal  peduncle  as 
long  as  the  eye,  and  much  longer  than  the  one  extending  from  the  end  of  the  anal  to  the 
root  of  the  caudal;  slender  and  narrow,  two-thirds  as  long  as  the  head.

A  single  individual  (No.  35604,  U.  S.  N.  M.),  the  type  of  the  species,  7£  inches  in  length, 
was  taken  by  the  Albatross  at  station  2201,  in  30°  30'  45"  N.  lat.,  71°  35'  15"  W.  Ion.,  at  a 
depth  of  538  fathoms.     Scopelus  Bonapartii  of  Cocco  and  Bonaparte  is  nearly  allied.

length  of  bead.  Snout  moderate,  with  obtuse  tip.  Cleft  of  mouth  slightly  oblique,  curved 
downward  below  eye.  Origin  of  dorsal  slightly  in  advance  of  origin  of  ventral;  equidistant 
from  origin  of  adipose  dorsal  and  anterior  margin  of  orbit.  Pectoral  half  as  long  as  ventral. 
Dorsal  ninth  taller  and  longer  than  anal,  but  closely  resembling  it  in  form. 

Mediolateral  photophores,  3;  anterolaterals,  one  or  two,  the  former  in  an  obliquely  verti-

This  species,  described  l>y  Cocco,  from  Sicily,  and  named  by  him  in  honor  of  Dr.  Carlo 
Gemellaro,  of  Catania,  a  local  geologist  of  note,  has  been  found  only  about  Messina,  where 
it  is  regarded  as  very  rare,  although  Giglioli  obtained  nine  individuals  at  the  time  of  his 
great  capture  of  scopelids,  in  September,  1878.  One  of  these  (Cat.  No.  11170,  U.  S.  N.  M.) 
was  given  by  him  to  the  National  Museum.

Scopelus  cnrttleuK,  Klvnzinger. 

Seopelm  (Notoscopelus)  cceruleua,  LtSTKEN,  Spolia  Atlantica,  260,  fig.  20. 

A  species  apparently  closely  related  to  L.  Gemellarii,  though  somewhat  more  slender,  as 
shown  in  the  figure  of  Liitken.  The  main  point  of  difference  appears  to  be  in  the  compar- 
atively elongate  anal  tin.  which  contains  nineteen  rays  instead  of  twelve,  as  in  L.  Oemelr 
larii,  but  the  figure  given  by  Liitken  does  not  show  an  elongate  anal  fin. 

LAMPANTCTUS  LACERTA,  Goode  and  Bean,  n.  s.     (Figure  89.) 

Height  of  the  body  one-fifth  total  length  (without  caudal);  length  of  head3J  times  in  total ; 
greatest  depth  of  head  two-thirds  of  its  length.  Eye  moderate;  its  diameter  contained  34 
times  in  length  of  head.  Snout  somewhat  obtuse,  rounded,  with  strong  keel;  its  length 
about  one-half  diameter  of  eye.  Cleft  of  mouth  somewhat  oblique,  maxillary  reaching  to 
angle  of  preoperculum  and  somewhat  dilated.  Origin  of  dorsal  is  much  nearer  tip  of  snout 
than  root  of  caudal.  Pectoral  slender,  its  middle  rays  elongate.  Ventrals  inserted  slightly 
behind  the  origin  of  dorsal,  and  reach  to  base  of  first  anal  ray.  Anal  inserted  behind  end 
of  dorsal  base.    Caudal  large,  forked.    Photophores  arranged  somewhat  as  iu  21.  punctatum. 

Mediolaterals,  3;  posterolateral,  1;  the  former  in  an  obliquely  vertical  row,  as  in  .1/. 
punctatum,  the  latter  under  the  soft  dorsal.  Precaudals  in  low  horizontal  line.  Number  of 
superanals  7+5.  Three  large  pits  in  the  mandibles  also  show  luminous  qualities.  Color, 
apparently  light  brown;  the  scales  opalescent. 

Radial  formula:  D.  13;  A.  15;  L.  lat.  about  30. 

This  species  is  described  from  three  specimens  (No.  43778,  U.  S.  N.  M.)  obtained  by  the 
Albatross  from  station  2401,  in  28°  38'  30"  N.  lat.,  85°  52'  30"  W.  Ion.,  at  a  depth  of  142

Eadial  formula:  D.  13;  A.  12;  L.  lat.  34-36  (36  in  the  specimen  examined). 

This  species,  as  described  by  Lowe  from  Madeira,  and  afterwards  obtained  by  Johnson 
from  the  same  locality,  has  also  been  found  in  the  Mediterranean.  The  National  Museum 
has  specimens  from  Messina,  presented  by  the  Royal  Zoological  Museum  of  Florence.  A 
single  specimen  (No.  32811,  U.  S.  N.  M.)  examined  by  us  was  obtained  by  the  Albatross 
from  station  2014,  in  36°  41'  05"  N.  lat.,  74°  38'  55"  W.  Ion.,  at  a  depth  of  373  fathoms,  in 
1883.     The  range  of  this  species  is  thus  extended  westward  nearly  4,000  miles. 

Two  individuals  (No.  21600,  U.  S.  N.  M.;  No.  199,  Gloucester  Donations),  the  longer 
80  millimeters  in  length,  the  other  68  millimeters,  were  taken  by  one  of  the  Gloucester  fish- 
ing vessels  on  the  fishing  banks.  Also,  No.  21689,  U.  S.  N.  M.  (No.  219,  Gloucester  Dona- 
tions), 75  millimeters  in  length.  Additional  specimens  (No.  28978,  U.  S.N.  M.),  in  very  bad 
condition,  were  taken  by  the  Fish  Hawk  from  station  1038,  in  39°  58'  N.  lat.,  70°  00'  W. 
Ion.,  at  a  depth  of  146  fathoms.  An  example  (No.  28934,  U.  S.  N.  M.),  72  millimeters  in 
length,  was  taken  by  the  Fish  Haick  from  station  1031,  in 39°  57'  N.  lat,,  69°  19'  W.  Ion.,  at

Notoscopehis.  Gt'NTnER,  Cat.  Fish.  Brit.  Mus.,  v,  1884,  405,  411  (as  suhgenusi. 

Myctophids,  with  the  dorsal  fin  much  longer  than  the  anal,  and  overlapping  the  anterior 
half  of  the  latter.  Body  elongate.  Snout  obstusely  conical;  jaws  equal  in  front;  cleft  of 
mouth  nearly  horizontal ;  maxillary  not  dilated  behind.  No  luminous  glands  on  head  or  tail. 
Arrangement  of  photophores  irregular:  anterolaterals,  1  or  none;  mediolaterals,  2  or  3; 
posterolaterals,  1,  2,  or  3.  Precaudals  2+1,  the  last  one  high  up,  and  between  the  flap  of 
the  operculum  and  the  lateral  line. 

The  type  of  this  genus  is  Lampanyctus  resplendens,  Richardson.  The  Eigenmanns  have 
set  apart  as  a  new  genus,  under  the  name  ••  Catablemella^  a  form  characterized  by  the  low 
pectorals,"  the  type  being  Kotoseopelus  brachyehir.     (Proc.  Cal.  Acad.  Sci.,  2d  ser.,  in,  24.) 

The  National  Museum  has  specimens  from  Nice  (Cat.  No.  40057,  U.  S.  N.  M.)j  sent  by 
the  Royal  Museum  at  Florence,  labeled  "  Scopelus  elonijatus."'  which  evidently  belong  to  this 
genus,  having  21  rays  in  the  dorsal,  17  or  18  in  the  anal,  the  height  of  the  body  contained 
5  times  in  its  length,  and  the  eye  one-fourth  the  length  of  the  head.  They  would  appear  to 
be  closely  related  to  iVr.  resplendens,  which,  however,  has  not  hitherto  been  announced  from 
the  Mediterranean.    This  form  is  evidently  that  described  and  figured  by  Costa.

Steindachner,  Vinciguerra,  Raffaelle,  and  Collett  seem  all  disposed  to  recognize  but  one 
species  of  Notoscopelus.  We  think  we  have  distinguished  four,  but  possibly  our  series  is 
not  sufficiently  complete  to  justify  us  in  positive  opinions.

Height  of  body  contained  4J  in  total  length  (without  caudal) ;  length  of  head  3i  times. 
Least  depth  of  tail  half  the  height  of  body.  Head  slightly  longer  than  high.  Eye  large, 
diameter  one-third  that  of  head.  Profile  almost  perpendicular,  an  elaborate  luminous  plate 
occupying  the  entire  space  between  the  eyes,  extending  backward  between  the  lower 
margin  of  the  orbit  and  the  upper  jaw  to  a  point  behind  the  vertical  from  the  middle  of  the 
orbit,  and  also  with  a  lobe  on  either  side  above,  impinging  upon  the  anterior  upper  limb  of 
the  orbit.  Cleft  of  mouth  slightly  oblique,  its  length  nearly  twice  the  diameter  of  the  orbit. 
The  maxillary  reaches  the  angle  of  the  preoperculum,  and  is  not  dilated  behind.  The  origin 
of  the  dorsal  and  ventral  tins  is  in  the  same  vertical,  that  of  the  latter  equidistant  from  the 
tip  of  the  snout  and  the  adipose  tin,  that  of  the  former  equidistant  from  the  anterior  margin 
of  the  orbit  and  adipose  tin.  The  insertion  of  the  last  dorsal  ray  over  the  origin  of  the 
first  anal  ray.  Pectoral  two  thirds  as  long  as  ventral,  its  tip  reaching  slightly  beyond  vertical 
connecting  origin  of  dorsal  and  anal.     Scales  smooth;  those  of  lateral  line  slightly  larger. 

The  photophores  are  small  and  not  very  conspicuous.  In  the  example  studied,  there  are 
11  iu  superanal  series,  there  being  a  broad  break  over  the  root  of  the  last  anal  rays,  with 
5  in  front  and  6  behind  it,  the  single  posterolateral  being  placed  far  above,  near  the  lateral 
line,  and  forming  an  equilateral  triangle  with  the  two  placed  on  either  side  of  the  break. 
Mediolaterals,  2,  placed  obliquely  and  far  apart,  the  anterior  and  highest  above  the  origin 
of  the  anal,  the  posterior  and  lower  about  midway  between  this  and  the  first  in  the  anal 
series,  which  is  over  the  interval  between  the  roots  of  the  third,  fourth  and  fifth  branched  rays 
of  the  anal  tin.    Anterolaterals,  3,  placed  in  the  form  of  an  isosceles  triangle,  the  apex  of

which  is  represented  by  the  most  anterior  of  the  group,  which  is  placed  over  the  axil  of  the 
ventral  and  about  three-fourths  of  thewayfrom  its  root  to  the  lateral  Hue;  a  fourth  photo 

phore,  possibly  also  to  be  grouped  here  is  nearly  midway  between  the  axil  of  the  pectoral 
and  the  axil  of  the  dorsal.     Radial  formula:   l>.  Ill,  13;  A.  111.  14;  L.  hit.  40. 

This  species  has  been  found  only  in  the  Mediterranean.  Etaflaele  had  six  specimens  from 
.Messina,  ami  Giglioli  obtained  two  Others  from  the  same  locality  in  the  latter  part  of  Sep- 
tember. 1878,  one  of  which,  presented  by  hiru  to  the  National  .Museum  (Cat.  14169),  is  the 
type  of  the  foregoing  description.  The  species  seems  to  be  exceedingly  rare,  even  in  the 
Mediterranean.  The  great  extension  and  elaboration  of  the  nasal  luminous  plate  shown  in 
the  figure,  may  be  due  to  sexual  conditions.  At  all  events,  as  has  been  remarked,  it  is 
unlike  that  shown  by  Raft'aele,  though  sufficiently  similar  to  that  of  Cocco  and  Bonaparte.

Height  of  body  contained  4A  times  in  total  length;  length  of  head  3§  times.  Least 
depth  of  tail  24,  in  height  of  body.  Head  considerably  longer  than  high,  its  height  equal  to 
distance  from  anterior  margin  of  pupil  to  end  of  opercular  flap.  Eye  moderate,  its  diameter 
nearly  one  fourth  length  of  head.  Snout  short,  but  less  declivous  and  obtuse  than  in 
,1.  metopoclampa.  A  pearl-colored  luminous  organ  touching  the  limb  of  orbit,  but  separated 
from  it  above  and  below,  with  posterior  lobe  not  prolonged  far  back,  and  with  a  space 
between  its  lower  margin  and  the  opening  of  the  jaw.  Cleft  of  mouth  oblique  and  curved, 
the  maxillary  reaching  to  augle  of  preoperculum  and  uot  dilated.  Origin  of  dorsal  and 
ventral  nearly  in  same  vertical,  that  of  former  midway  between  anterior  margin  of  orbit 
and  adipose  tin:  that  of  latter  midway  between  tip  of  snout  and  adipose  fin.  Insertion  of 
the  last  ray  of  dorsal  is  over  interspace  between  third  aud  fourth  rays  of  anal.  Pectoral 
(unless  mutilated)  only  half  as  long  as  ventral,  and  its  tip  does  not  approximate  the  vertical 
from  its  origiu.  Dorsal  and  anal  similar,  the  former  with  its  upper  margin  concave.  Adi- 
pose dorsal  iuserted  over  interspace  betweeu  antepenultimate  and  penultimate  anal  rays, 
and  as  long  as  ultimate  dorsal  ray.     Scales  smooth,  those  of  lateral  line  scarcely  enlarged. 

Iu  the  type  there  are  thirteen  photophores  in  the  anal  series;  a  wide  break  over  the 
roots  of  the  last  two  rays  of  the  anal  tin.  No  posterolaterals.  Two  mediolaterals,  the 
anterior  the  lowest.  Two  anterolaterals,  theanterior  and  highest  very  small,  above  the  axil

between  this  and  the  anterior  of  the  mediolateral  group,  and  forming,  with  the  two  photo- 
phores in  that  group,  an  obtuse  isosceles  triangle,  with  the  anterior  of  the  l lial  group  at 

its  apex.  Of  the  four  precaudal  photophores  the  last  three  are  the  most  nearly  together, 
and  form  a  nearly  vertical  line  at  the  base  of  the  lower  caudal  lobe.  There  is  a  large,

tween  antepenultimate  and  ultimate  anal  rays.  Pectoral  stout  and  much  shorter  than  ven- 
tral, not  reaching  much  more  than  half  way  to  its  root.  Scales  smooth,  those  in  the  lateral 
line  somewhat  enlarged,  shiny,  and  conspicuous;  the  lateral  line  descending  in  a  gentle  cat- 
enary curve  to  a  poiut  above  the  origin  of  the  ventral.  The  arrangement  of  the  photo- 
phores  is  very  peculiar,  and  can  best  be  understood  by  an  examination  of  the  figure.  There  is 
a  break  in  the  series  of  superanals,  there  being  live  on  the  lower  part  of  the  caudal  peduncle 
behind  the  extremity  of  the  anal.  There  are  apparently  two  posterolaterals,  the  pos- 
terior and  highest  near  the  lateral  line,  and  forming  the  beginning  of  a  series  of  S,  arranged 
in  the  arc  of  a  circle,  the  last  being  the  highest  in  the  group  of  mediolaterals,  of  which  there 
are  4.  There  is  but  one  anterolateral,  which  is  above  the  axil  of  the  ventrals,  slightly 
behind  it  and  about  midway  between  it  and  the  lateral  line.  There  is  a  large,  triangular, 
luminous  patch  in  the  space  between  the  axil  of  the  pectoral  and  the  flap  of  the  operculum, 
which  covers  its  anterior  portion,  aud  is  itself  decorated  with  a  circular  photophore. 
There  appears  to  be  a  luminous  patch  along  the  anterior  margin  of  the  preoperculum.

A  Myctophum  with  a  stout,  short  body,  moderately  compressed;  with  a  rounded,  blunt 
snout,  very  large  mouth,  comparatively  small  eye;  comparatively  short,  triangular  dorsal 
and  anal,  the  former  entirely  in  advance  of  the  latter  aud  inserted  very  far  forward. 

Height  of  body  4  times  in  total  length;  length  of  head  3  times.  Depth  of  body  one- 
fourth  of  total  length.  Caudal  peduncle  stout;  its  height  nearly  one-half  height  of  body. 
Eye  moderately  large,  its  diameter  contained  2|  times  in  length  of  head;  distance  between

DISCUSSION   OF   SPECIES    AND    THEIR    DI8TRIB1  Tlo.V.  89 

This  species,  first  described  by  Oocco  from  the  Mediterranean,  is  abundant  about  Sicily. 
but  has  oever  before  been  found  in  the  At  Ian  tic  The  descriptions  of  Cocco  and  Bonaparte 
were  too  general  for  use  in  comparison,  also  thai  of  Giinther,  being  founded  upon  a  small 
number  of  very  minute  specimens,  especially  as  it  lias  few  rays  in  the  anal  and  the  propor- 
tions of  the  head  and  eye  peculiar  to  very  young  specimens. 

It  is  with  peculiar  pleasure  that  we  add  to  tlie  fauna  of  America  a  species  identified 
with  the  name  of  Rafinesque,  who  was  the  first  to  call  attention  to  the  genus  to  which  it 
belongs.  The  three  specimens  (No.  .'i;r>.">o,  U.  S.  K  M.)  described  by  us,  the  largest  of 
which  is  77  millimeters  long,  with  imperfect  tail,  were  taken  by  the  steamer  Albatross  in 
37°12'20"  N".  lat.,  69  39'  W.  Ion.  These  have  been  studied  in  connection  with  ample 
material  from  Messina  (No.  40058,  U.  S.  N.  M.),  received  from  the  Florence  Museum.

Myctophids,  similar  in  form  and  proportions  to  the  typical  genus  of  the  family,  though 
stouter,  with  a  very  much  wider  and  less  oblique  mouth,  pectoral  placed  lower,  and  with 
opercular  apparatus  much  more  obliquely  articulated.  Dorsal  and  anal  similar,  not  touch- 
ing the  same  vertical.  The  glandular  photophore  in  front  of  each  eye  below  the  nostril,  and 
the  pearl  like  photophores  upon  the.  sides  divided  into  halves  by  a  septum  of  black  pig- 
ment.    No  caudal  photophores.     Postlaterals,  2,  in  obliquely  ascending  row. 

The  type  of  this  genus  is  Diaphus  theta,  Eigenmann  and  Eigenmann,  he.  cit.,  from  mod-

Height  of  body  4J  (perhaps  in  females)  to  5  in  total  length.  Length  of  head  contained 
rather  more  than  5  times  in  length  (without  caudal).  Tail  slender,  elongate,  its  least  depth 
one-fourth  of  the  height  of  the  body.  The  diameter  of  the  eye  is  contained  4  times  in  the 
length  of  the  head.  Distance  between  the  posterior  margin  of  the  orbit  and  the  preoper- 
cular  edge  is  two-thirds  of  the  diameter  of  the  eye.  Preopercular  edge  obliquely  descending 
backwards.  Snout  conical,  the  upper  part  projecting  beyond  the  lower,  the  upper  and 
lower  profiles  nearly  equally  curved.  The  maxillary  extends  to  the  angle  of  the  preoper- 
culum  and  is  scarcely  dilated.  The  dorsal  origin  is  nearer  to  the  end  of  the  snout  than  to 
the  root  of  the  caudal,  and  behind  the  base  of  the  ventral;  the  last  ray  of  the  dorsal  is  in 
the  vertical  from  the  second  or  third  anal  ray.     Pectoral  extends  to  the  middle  of  ventral. 

In  some  specimens  each  of  the  scales  on  the  back  of  the  tail  has  a  pearl-colored  dot; 
this  is  probably  a  sexual  character  of  the  male.  The  back  and  the  nape  are  blackish;  sides 
silvery,  with  gold  and  silver  reflections.  The  inside  of  the  mouth  is  blackish,  the  iris 
silvery,  the  pupil  transparent.     Eadial  formula:  D.  10-12;  A.  20-21;  V.  8;  1  |  41  |  3. 

This  species,  although  said  to  be  very  rare  in  the  Mediterranean,  would  appear  to  be 
one  of  the  most  abundant  of  the  surface  forms  in  the  Western  Atlantic,  for  many  hundreds 
of  specimens  have  been  obtained  by  the  Albatross  at  the  surface,  often  from  twenty  to  fifty 
in  a  single  locality  taken  with  a  dip  net;  sometimes  by  electric  light  after  dark.

A  species  closely  resembling  8.  Coccoi,  in  form,  but  having  a  single  anterolateral  photo- 
phore,  placed  much  as  in  8.  Coccoi,  and  three  posterolaterals  in  an  obliquely  vertical  row, 
arranged  as  in  Myctophum  punctatum.  Pectoral  fin  long,  falcate,  passing  far  beyond  the

the  specimens  identified  by  us  with  8.  Coccoi.  It  occurs  in  almost  every  lot,  and  therefore 
a  new  list  of  localities  is  not  given.  It  seems  not  impossible  the  form  may  eventually  be 
found  to  be  a  sexual  variation  of  8.  Coccoi. 

RHLNOSCOPELUS  RARUS,  Lutken. 
Scopelua  (BtAnoaeopeliu)  rarus,  i>i  tm:n,  Spolia  Atlantica,  11,  1892,  246,  fig.  4. 

This  species,  described  by  Liitken,  seems  to  differ  from  the  other  species  of  this  genus  in 
many  important  particulars,  and  but  for  the  unquestioned  accuracy  and  thorough  insight 
which  this  authority  has  always  manifested,  an  inspection  of  the  figure  would  lead  us  to 
question  whether  it  properly  belongs  here.  The  peculiar  arrangement  of  thephotophores,  and 
the  presence  of  a  luminous  plate  upou  the  top  of  the  caudal  peduncle  distinguish  it  at  once 
from  all  the  others,  as  well  as  does  the  shape  of  the  body,  which  is  more  like  that  of  Myc- 
tophum,  the  short  anal  fin,  the  overlap  of  the  dorsal  with  the  anal,  and  the  comparative 
shortness  and  thickness  of  the  caudal  peduncle,  and  also  the  nearly  vertical  direction  of  the 
preopercular  limb.  The  most  characteristic  feature  in  the  arrangement  of  the  photophores 
is  the  almost  entire  absence  of  the  postventral  series  and  the  number  of  photophores  in  the 
Buperanal  series,  comparatively  much  smaller  than  in  8.  Coccoi. 

ELECTRONA,  Goocle  and  Bean,  n.  g. 

Myctophids  having  dorsal  and  anal  fins  slightly  overlapping.  The  lateral  line  with  scales 
much  enlarged;  scales  hard,  persistent.  Luminous  gland  on  top  of  the  caudal  peduncle,  but 
none  on  head.  Anal  longer  than  dorsal,  and  passing  behind  the  vertical  from  soft  dorsal. 
Body  ovate,  compressed;  head  short;  profile  declivous;  snout  not  projecting.  Caudal  pedun- 
cle short  and  stout.    No  posterolateral  photophore.     (Type,  Scopelus  Ris.soi,  Cocco.)

No  description  is  necessary  of  this  well  known  species,  but  for  the  first  time  is  presented 
a  good  figure  of  a  specimen  sent  to  the  National  Museum  by  the  Royal  Museum  in  Florence. 

We  are  greatly  in  doubt  as  to  the  relationships  of  this  form,  but  it  is  provisionally  placed 
near  RhinoscojH  Iks  on  account  of  the  resemblance  in  the  scales. 

DASYSCOPELUS,  Gunther. 

Dasi/scopelus,  GOnther,  Cat.  Fish.  Brit.  Mus.  v.,  1864,  105,  ILL. 

Myctophid  fishes,  having  the  dorsal  and  anal  fins  touching  the  same  vertical,  but  not 
overlapping; somewhat  emarginate.  Scales  of  lateral  line  much  enlarged,  hard,  persistent, 
ctenoid.  Anal  terminating  below  soft  dorsal.  Body  elevated,  somewhat  compressed.  Caudal 
peduncle  rather  slender;  luminous  scales  on  the  back  of  the  caudal  peduncle.  The  arrange 
ment  of  the  photophores  much  as  in  Myctophum :  2  anterolaterals;  2  tnediolaterals; •  pos- 
terolateral, far  in  advauce  of  the  break  in  the  anal  series,  1'  precaudals,  the  last  at  the  end 
of  the  lateral  line. 

The  type  of  this  genus  is  Scopelus  asper  and  Gunther  assigns  to  it  also  s.  subasper,  from 
the  Pacific.    (For  I),  spinosus,  Steindachner,  see  Appendix).

1864,  411. 

The  height  of  the  body  is  one-fourth  of  the  total  length  (without  caudal),  the  length  of 
the  head  two  sevenths;  the  least  depth  of  the  tail  is  one-third  of  the  height  of  the  body; 
the  depth  of  the  head  is  contained  1£  times  in  its  length.  Eye  very  large,  two-fifths  of  the 
length  of  the  head;  distance  between  the  posterior  margin  of  the  orbit  and  the  preoperculur 
edge  equal  to  one-third  of  the  diameter  of  the  eye;  posterior  margin  of  the  preoperculum 
vertical.  Snout  extremely  short  and  obtuse,  with  its  upper  profile  abruptly  bent  down- 
wards. Cleft  of  the  mouth  nearly  horizontal  with  the  lower  jaw  received  within  the  upper. 
The  maxillary  reaches  nearly  to  the  angle  of  the  preoperculum,  and  is  gradually  and  slightly 
dilated  behind.  The  origin  of  the  dorsal  fin  is  considerably  nearer  to  the  extremity  of  the 
snout  than  to  the  root  of  the  caudal,  and  immediately  behind  the  base  of  the  ventral;  its 
last  ray  is  a  little  before  the  origin  of  the  anal.  The  pectoral  extends  to  the  middle  of  the 
ventral,  which  is  the  shorter.  Scales  with  the  margins  strongly  serrated;  those  of  the 
lateral  line  are  much  larger  than  the  others.  Some  of  the  adult  specimens  have  a  pearl- 
colored  matter  imbedded  in  the  substance  of  the  scales  on  the  back  of  the  tail.     (Giinthtr.)

DASYSCOPELUS  SPINOSUS  (Steindachner). 

Scopelus  spinosua,  Steindachner,  LOtken,  Spolia  Atlantica,  n,  1892,  239,   pi.  I,  rig.  2. 

A  species  described  and  figured  by  Liitkeu,  of  which  he  had  a  number  of  specimens 
from  the  Atlantic  from  the  following  localities:  X.  lat.  14°  11',  W.  Ion.  29° 32';  N.  hit.  9  ,

S.lat.  7  '  6',  \Y.  Ion.  7  30',  as  well  as  others  from  the  central  Pacific.  It  differs  from  />.  osper 
chiefly  in  the  character  of  the  lateral  line,  which  in  Richardson's  figure  of  />.  osper  has  the 
scales  very  much  enlarged.    The  arrangement  of  the  photophores  is  much  the  same. 

DASYSCOPELUS  SUBASPER  (Qunther). 

Scopelus  subotper,  Gcnthf.r,  Cat.  Fish.  Brit.  Mus.,  v.  411.— LOtken,  Spolia  Atlantica,  n,  1892,  240,  fig.  1. 

Gunther  described  this  species  from  the  Pacific  Ocean  (lat.  73°  30'  S.  Ion.  123°  E.) 
and  Liitkeu  identifies  from  the  Atlantic  a  species  under  this  name,  which  he  distinguishes 
from  the  others  by  the  absence  of  the  break  in  the  superanal  scries  of  photophores,  the 
absence  of  the  posterolateral  photophore,  the  arrangement  of  the  anterolaterals  and  medio- 
laterals  in  groups  of  two  each,  and  also  a  peculiarly  inverted  triangular  patch  of  the  pie- 
pectorals.

The  type  of  this  species  is  a  single  specimen,  0.1  inches  long,  in  the  British  .Museum, 
obtained  off  Madeira  in  January,  18<i3.  The  Albatross  obtained  a  specimen  on  February  11, 
1885,  from  station  2370,  in  31°  03'  15"  K  lat.,  88°  lti'  W.  Ion.,  at  a  depth  of  324  fathoms. 
The  Blake  obtained  two  specimens,  one  off  Dominica,  in  333  fathoms,  and  one  from  Sta- 
tion xlii,  off  Martinique,  in  357  fathoms.  The  French  expedition  obtained  it  from  off  the 
coast  of  Morocco,  1,350  and  L,590  meters.  The  Investigator  took  it  in  the  Indian  Ocean  in 
188-220  fathoms. 

The  color  of  the  Albatross  specimen,  as  noted  immediately  after  capture  by  Dr.  Bean, 
was  as  follows:  Grayish  silver  on  sides,  with  narrow  margins  of  claret  red  on  the  scales  (or 
scale  impressions).  All  the  fins  with  brick-red  on  membrane  covering  the  rays.  Iris,  pale 
gold.  Preoperculum  aud  interopercle  with  narrow  lines  of  red.  Bone  supporting  brauchi-

!U  DISCUSSION   OF    SPECIES   AND    THEIR    DISTRIBUTION. 

NANOBRANCHIUM  MACDONALDI,  Goode  and  Bean,  n.  s.     (Figure  110). 

Height  of  body  contained  5  in  total  length;  head  31  times.  Bye  moderate,  its  diameter 
contained  5  times  in  length  of  head,  and  considerably  greater  than  that  of  snout.  Mouth 
extremely  wide;  rather  oblique;  with  lower  jaw  somewhat  projecting,  extending  backwards 
to  end  of  preoperculum.  Intermaxillary  as  long  as  maxillary,  toothed  throughout  its  entire 
length;  both  bones  narrow  and  rod-shaped.  Gill  lamina*  very  short;  gill  rakers  long, 
needle-shaped,  the  longest  a  little  longer  than  eye.  Origin  of  dorsal  nearer  extremity  of 
snout  than  root  of  caudal,  its  last  ray  opi)osite  fourth  or  tilth  ray  of  anal,  while  the  origin 
of  anal  is  opposite  tenth  ray  of  dorsal ;  the  longest  ray  of  the  latter  equal  to  length  of  head 
without  snout.  Adipose  fin  small,  opposite  penultimate  ray  of  anal.  Caudal  much  forked. 
Pectoral  composed  of  three  or  four  small,  short,  delicate  rays.  Ventral  inserted  slightly 
in  advance  of  dorsal,  and  extending  to  vent.  Phosphorescent  organs  arranged  much  as  in 
N~.  nigrum.  The  glandular  organ  of  white  upon  the  top  of  the  caudal  peduncle  is  much 
smaller  than  that  described  for  X.  nigrum,  but  has  possibly  been  partially  obliterated;  the 
one  on  the  lower  part  of  the  peduncle  is  much  larger.    Coloration,  purplish  blown.

eries. It  appears  clearly  distinguished  from  X.  nigrum,  Giinther,  obtained  by  the  Chal- 
lenger south  of  the  Philippine  Islands,  at  a  depth  of  500  fathoms.  This  species  is  described 
from  a  single  specimen  (Xo.  3947S,  U.  S.  X.  M.)  5  inches  in  length,  obtained  by  the 
Albatross  from  station  2553,  in  39°  48'  N.  lat.,  70°  36'  W.  Ion.,  at  a  depth  of  551  fathoms. 

In  an  individual  (Xo.  494S1,  U.  S.  X.  M.),  taken  by  the  Albatross  from  station  2549,  in 
39°  51'  30"  X.  lat.,  70°  17'  W.  Ion.,  the  pectoral  is  much  more  developed  than  in  any  of  the 
types,  its  length  being  two-fifths  that  of  the  head,  and-  readies  nearly  to  origin  of  ventral.

SCOPELOSAURUS,   Bleeker. 

Scopeloeaurus,  Bleeker,  citation. 

This  genus  stands  far  apart  from  all  the  others  in  the  family,  having  a  cylindrical  body, 
with  small  scales,  median  dorsal,  and  teeth  in  the  lower  jaw  in  several  series.  It  is  repre- 
sented by  a  single  species,  S.  Hoedti,  Bleeker,  from  Amboyua,  and  it  is  not  known  whether 
or  not  it  is  abyssal  in  its  habits.

MaurolUidir,  Giix  (MS.). 

Body  somewhat  elongate,  compressed,  scaleless.  Barbels  Done.  Margin  of  the  apper 
jaw  formed  by  the  maxillary  and  intermaxillary,  both  of  which  are  provided  with  teeth. 
Opercular  apparatus  incomplete.  Gill  opening  very  wide,  tl ater  branchial  arch  extend- 
ing forward  to  behind  the  symphysis  of  the  lower  jaw.  Psendobranchise  present.  Air 
bladder  none.  Adipose  tin  rudimentary.  Series  of  luminous  phosphorescent  spots  along 
the  lower  side  of  the  bead,  tail,  and  body.  A  single  dorsal  tin,  without  spinous  rays.  The 
remarkable  form  Op  tat  hup  root  us,  Vaillaut  (fig.  112),  perhaps  belongs  here.

Body  compressed,  naked,  silvery ;  phosphorescent  bodies  upon  the  lower  parts.  Mouth 
moderate.  Maxillary  bones  dilated,  forming  nearly  the  entire  margin  of  the  upper  jawr; 
intermaxillaries  small;  lower  jaw  included.  Teeth  inconspicuous,  a  few  near  the  symphysis 
of  the  lower  jaw,  while  the  edge  of  the  maxillary  is  finely  serrated.  Eyes  moderate  in  size, 
separated  by  a  very  narrow  interorbital  area.  Pectorals  placed  very  low.  Ventrals  pres- 
ent. Dorsal  nearly  median.  Adipose  fin  rudimentary.  Anal  moderate.  Caudal  forked. 
Gill  opening  extensive,  outer  branchial  arch  reaching  to  behind  the  symphysis  of  the  lower 
jaw,  with  numerous  short  gill  rakers. 

The  recent  tendencies  of  opinion  among  American  zoologists  are  not  in  accord  with  the 
action  of  Dr.  Giiuther  in  substituting  Coccia  for  Ivhthyocuccus.

No  pseudobranchiai.    No  gill  rakers.     Branchiostegals  numerous.     {Jordan  and  Gilbert.) 

The  question  of  the  presence  or  absence  of  the  air  bladder  having  never  been  inves- 
tigated, a  dissection  by  Dr.  Bean  has  revealed  the  presence  of  a  conspicuous  but  thin-walled 
organ.  The  specimen  (No.  35626,  U.  S.  N.  M.)  taken  by  the  Albatross  shows  long,  slender 
ovaries,  with  small  but  perfectly  distinct  eggs.

The  height  of  the  body  is  contained  5i  times  in  the  total  length  (without  caudal) ;  the 
length  of  the  head  1  times.  Jaws  heterodont,  the  intermaxillary  being  armed  with  2,  the 
maxillary  with  about  12  large,  distinct  teeth,  the  spaces  between  them  being  filled  with  very 
small  teeth;  lower  jaw  similarly  armed  with  10  or  11  large  teeth.  The  entire  cheek  is  cov-

This  species  is  known  to  be  common  in  the  Mediterranean  and  the  neighboring  parts  of 
the  Atlantic,  especially  off  Madeira. 

Its  first  occurrence  in  the  western  Atlantic  was  in  1881,  when  it  was  trawled  by  the 
Fish  Hawk  off  the  New  England  coast.  It  was  also  obtained  by  the  Albatross,  at  station 
2665  in  263  fathoms,  and  by  the  French  expedition,  in  1,180  meters,  off  the  coast  of  Morocco 
and  off  the  Cape  Verdes,  in  160-5S0  meters.

physis  of  the  lower  jaw.  On  the  palatines  and  possibly  upon  the  pterygoids  a  few  small, 
sharp,  pointed  teeth.  Oil  I  opening  \  ery  wide;  the  gill  rakers  long  and  thin.  Preoperculum 
rounded.  Twelve  short  branchiostegals;  ;it  the  base  of  each  of  the  8  anterior  onesa  lumi

covered  with  teeth  similar  to  those  in  the  jaws,  bul  in  severalrows.  The  dorsal  has  its 
origin  nearly  midway  between  the  ventral  and  the  anal,  ami  is  composed  of  l.">  or  1  I  rays. 
Adipose  tin  thread-like.  Ventral  in  front  of  the  middle  of  the  body  (no1  behii  d,  as  stated 
by  Kner)  with  7  rays,  reaching  to  the  vent.  Anal  with  from  17  to  19  rays,  beginning  under 
the  last  3  or  4  rays  of  the  dorsal,  and  the  fin  similar  in  heigh!  to  the  dorsal.  The  cau- 
dal is  equal  in  length  to  that  of  the  head  from  snout  to  preoperculum,  and  is  strongly 
forked.  Pectoral  small,  pointed,  and  nearly  as  long  as  the  caudal.  The  thin,  caducous 
scales  with  which  the  body  is  covered  exhibit  no  radiating  lines,  simply  delicate,  concen- 
tric rings.  On  either  side  two  longitudinal  rows  of  inconspicuous  phosphorescent  spots, 
surrounded  with  black  pigment;  the  lower  row  near  the  line  of  the  belly  begins  near  the 
throat  and  ends  at  the  origin  of  the  anal.  In  the  space  from  the  pectoral  to  the  ventral  are 
16  spots;  between  the  ventral  and  the  anal  11;  the  upper  row  commences  with  2  large 
spots  upon  the  suboperculum,  and  continues  back  to  the  caudal.  Color,  dark  gray;  the  back 
and  belly  silvery;  all  the  fins  whitish,  uniform  color.

'flu's  form,  described  in  1870  by  Kner  from  a  single  badly  damaged  specimen  taken  in 
the.  Atlantic,  is  evidently  a  true  Gonostoma.  It  closely  resembles  in  many  respects  Mauro- 
liens  Poweriee  and  Maurolicus  attenuatus  of  authors,  which  seem  to  have  little  affinity  with 
the  typical  species  of  Maurolicus. 

We  have  before  us  a  specimen  taken  by  the  Blake  from  Station  ccxlv,  off  Havana,  at  a 
depth  of  243 fathoms.  Other  specimens  were  taken  by  the  Blake  from  Station  xliii,  off 
Grenada,  at  a  depth  of  461  fathoms;  from  Station  xxrv,  off  Grenada,  atadepth  ofl61  fath-

Body  elongate,  somewhat  compressed,  apparently  devoid  of  scales;*  lower  parts  with 
inconspicuous  series  of  luminous  spots,  with  the  latter  arranged  approximately  as  in  Gono- 
stoma, but  usually  much  less  conspicuous.  Head  conical,  compressed ;  cleft  of  mouth  very 
wide,  oblique,  extending  behind  the  eye.  The  lower  jaw  strongly  projecting.  Maxillary

caudal  rays,  its  width  being  less  than  two-thirds  of  its  height.  Its  height  at  the  ventrals 
is  contained  8J  times  in  standard  length;  the  least  height  of  tail  is  half  that  of  the  body  at 
the  ventrals. 

Cheek  naked.  Head  length  contained  4§  times  in  body  length,  its  width  about  one 
third  of  its  length.  The  intermaxillary  is  very  short,  extending  to  vertical  from  posterior 
limb  of  anterior  nostril.  The  maxillary  is  very  strongly  curved  downward,  and  has  a  short 
kn  jl>  at  its  anterior  extremity,  not  visible  without  dissection.  The  maxillary  extends  back- 
ward to  a  distance  from  the  tip  of  the  snout  equal  to  the  length  of  the  head  without  the 
snout.  The  peculiar  arrangement  of  the  teeth  is  described  above  in  the  generic  diagnosis. 
Most  of  those  in  the  maxillary  are  inclined  strongly  forward.  Gill  rakers,  9  above  the  angle 
and  13  or  14  below. 

The  long  lower  jaw,  with  the  exception  of  the  projecting  tip,  is  included  within  the 
upper  jaw;  its  length  is  equal  to  the  distance  from  the  anterior  nostril  to  the  end  of  the 
head. 

Eye  circular,  close  to  the  profile,  the  iuterorbital  area  being  very  narrow.  Its  length 
is  equal  to  that  of  the  snout,  and  contained  7  times  in  tin?  length  of  the  head. 

Dorsal  fin  inserted  at  a  distance  from  the  tip  of  the  snout  equal  to  3  times  the  length 
of  the  lower  jaw,  its  base  being  as  long  as  the  head;  the  first  ray  is  minute  and  about  two- 
thirds  as  long  as  tin'  eye;  the  second  ray  is  about  two-thirds  the  length  of  the  base  of  the 
fin,  and  the  subsequent  rays  rapidly  and  uniformly  decrease  in  length  to  the  last,  which  is 
about  twice  as  long  as  the  first.    All  the  rays  except  the  first  are  bifid. 

The  anal  tin  is  inserted  under  the  second  ray  of  the  dorsal;  its  base  is  half  as  long  again 
as  that  of  the  dorsal,  and  nearly  one-third  as  long  as  the  body  of  the  fish;  its  outline 
resembles  that  of  the  dorsal,  though  slightly  emarginate,  its  longest  ray  a  little  longer  than 
the  longest  of  the  dorsal,  and  half  as  long  as  the  base  of  the  fin.  All  the  rays  except  the 
first  are  bifid. 

Caudal  forked,  its  middle  rays  less  than  half  as  long  as  the  outer  rays,  equal  in  length 
to  least  height  of  caudal  peduncle. 

Pectoral  inserted  under  the  tip  of  the  opercular  flap,  its  length  equal  to  the  greatest 
height  of  the  body. 

Ventral  inserted  at  a  distauce  from  the  snout  equal  to  twice  the  length  of  the  head,  its 
length  slightly  exceeding  that  of  the  pectoral,  and  contained  7  times  in  the  standard  body 
length.

(  olor  blackish  brown,  the  luminous  pores  inconspicuous,  in  a  row  in  each  side  from  the 
pectoral  region  to  the  tail,  and  another  below  it  from  the  throat  to  the  origin  of  the  anal. 

The  Challenger  obtained  this  form  first  from  great  depths  near  Bermuda,  but  subse- 
quently at  numerous  localities  in  the  Atlantic,  Pacific,  and  Antarctic  Oceans,  at  depths  of 
from  500  to  2,900  fathoms;  and  it  has  since  also  been  obtained  from  very  numerous  local 
ities  in  the  Atlantic  by  the  Albatross  and  the  Blake.  Although  many  hundreds  of 
specimens  are  in  the  National  Museum,  the  species  is  so  exceedingly  delicate  and  hard  to 
preserve  that  not  one  of  them  gives  satisfactory  opportunity  for  study. 

Neostoma  quadrioculatum,  Yaillant,  pi.  vin,  fig.  2,  must  be  very  similar  to  this  species 
(Exp.  Sci.  Trav.  et  Talisman,  99). 

According  to  Alcock,  O.  microckm  has  been  found  by  the  Investigator  in  the  Bay  of

BONAPARTIA,  Goode  and  Bean,  n.  g. 

Body  oblong,  compressed,  slender  behind,  as  in  Gonostoma;  covered  with  large  cycloid 
scales,  nearly  equal  in  size.  A  continuous  row  of  photophores  on  either  side  of  the  ventral 
line  upon  the  lowest  row  of  scales,  extending  from  the  anterior  part  of  the  lower  jaw  to  the 
extremity  of  the  base  of  the  anal;  others  upon  the  caudal  peduncle.  Head  much  com- 
pressed, cleft  of  mouth  very  wide.  Intermaxillary  short;  maxillary  long,  curved,  forming 
tlic  entire  margin  of  the  upper  jaw,  extending  to  the  angle  of  the  preoperculum.  Jaws 
armed  with  a  single  series  of  not  very  numerous,  acicular  teeth,  uniform  in  size;  minute 
teeth  on  the  palatines  and  pterygoids.  Eye  moderate.  Pectoral  and  ventral  fins  small. 
1  tarsal  tin  on  the  hinder  half  of  the  body,  opposite  the  anterior  portion  of  the  anal.  Adipose 
tin  absent.  Anal  much  longer  and  higher  than  dorsal.  Caudal  (probably)  subtruncate. 
Gill-opening  exceedingly  wide,  the  branchial  aperture  extending  nearly  to  the  dorsal  line 
on  either  side,  and  extending  forward  also  to  the  symphysis  of  the  lower  jaw.  Gill-rakers 
very  long. 

This  species  is  named  in  honor  of  the  Prince  of  Canino,  whose  admirable  work  upon  the 
fishes  of  Italy,  one  of  the  most  essential  of  the  older  works  in  the  ichthyologist's  library,  is 
especially  full  in  its  discussion  of  the  fishes  allied  to  the  one  now  under  discussion. 

BONAPARTIA  PEDALIOTA,  GOODE  and  Bean,  n.  s.     (Figure  120.) 

Body  elongate,  compressed,  its  height  contained  4J  times  in  its  total  length  (without 
caudal);  length  of  the  head  .'i.V  times.  The  diameter  of  the  eye  is  about  equal  to  the  length 
of  the  snout,  and  about  one -fifth  of  the  length  of  the  head;  width  of  interorbital  space  less 
than  diameter  of  the  eye.  Mouth  large,  oblique,  the  lower  jaw  slightly  projecting;  the 
upper  jaw  reaches  back  to  the  angle  of  the  preoperculum,  and  is  convex  on  its  lower  edge 
between  the-verticals  from  the  anterior  and  posterior  margins  of  the  eye.  The  pre- 
operculum extends  backward  in  a  sharp  angle.  The  origin  of  the  dorsal  fin  is  equidis* 
tant  from  the  root  of  the  ventral  and  the  axil  of  the  posterior  anal  ray.  and  in  the  vertical 
from  the  base  of  the  fourth  or  fifth  anal  ray:  its  length  of  base  about  two-fifths  of  that  of 
the  anal,  and  a  little  more  than  half  the  length  of  the  head.  Its  greatest  height,  which  is 
anteriorly,  about  equal  to  the  length  of  its  base.  The  space  between  this  and  the  root  of 
the  caudal  is  equal  to  the  length  of  the  upper  jaw.  The  origin  of  the  anal  is  equidistant 
from  the  posterior  margin  of  the  orbit  and  the  base  of  the  middle  caudal  rays.  Its  ante- 
rior third  is  greatly  prolonged,  falcate  in  form,  giving  to  the  lower  outline  of  the  fin  a  para- 
boloid curve.  The  length  of  the  longest  or  third  ray  is  about  equal  to  the  length  of  the 
base  of  the  fin,  and  nearly  four  times  the  length  of  the  twelfth  ray.  Posteriorly  to  the  end 
of  the  dorsal  the  fin  is  low,  decreasing  from  a  length  equal  to  the  diameter  of  the  orbit,  to

about  half  this  dimension  in  the  ultimate  rays.  The  pectorals  and  ventrals  are  short  and 
feeble,  the  central  inserted  about  midway  between  the  tip  of  the  snout  and  the  rout  of  the 
caudal  fin.  Pectoral  about  midway  from  the  tip  of  the  snout  to  the  origin  of  the  anal.  The 
caudal  apparently  about  equal  to  the  head  in  its  length,  l>ut  being  mutilated,  its  form  can- 
not be  accurately  determined.  The  scales  resemble  those  of  Gonostoma,  withoul  radiating 
lines.  ,\  single  row  of  rather  conspicuous  phosphorescent  spots  extends  from  the  lower 
jaw  beneath  the  eye,  to  the  end  of  the  anal  on  either  side,  these  dots  being  heavily  mar- 
gined and  with  Mack  above.  There  are  twelve  of  these  between  the  branchial  opening 
and  the  origin  of  the  ventral,  five  between  the  ventral  and  the  anal,  sixteen  in  the  anal 
series,  and  two  upon  the  caudal  peduncle,  one  at  the  origin  of  the  lower  caudal  rays,  the 
other  in  the  vertical  above  it  and  about  one-liftb  of  thedistance  from  the  dorsal  outline.  A 
series  of  vertical,  elongated  spots,  apparently  phosphorescent,  upon  either  side  of  the  lower 
jaw,  giving  it  a  pectinate  appearance. 

Color  (in  alcohol)  brownish  gray;  the  head  with  silvery  reflections. 

Radial  formula:  D.  20;  A.  30;  L.  lat.  46. 

The  types  of  this  species  are  two  specimens,  about  one  and  two  inches  long  respect- 
ively, obtained  by  the  steamer  Albatross  from  station  2042  in  25°  20'- 30"  N.  Lat.,  70°  58' 
W.  Long.,  at  a  depth  of  of  217  fathoms. 

YARRELLA,  Goode  and  Bean,  n.  g. 

Body  elongate,  compressed,  covered  with  rather  large,  thin,  deciduous  scales;  the  lower 
parts  with  luminous  spots.  Head  conical,  compressed;  cleft  of  mouth  very  wide,  oblique, 
extending  behind  the  eye.  Lower  jaw  strongly  projecting.  Intermaxillary  comparatively 
long,  forming  about  half  of  margin  of  upper  jaw.  Upper  jaw  with  a  single  row  of  teeth  in 
the  maxillary,  and  a  double  row  in  the  intermaxillary,  interspersed  with  occasional  stronger 
teeth;  those  in  the  intermaxillary  directed  downward  or  backward,  those  in  the  maxillary 
somewhat  forward.  Mandible  with  double  row  of  small  teeth,  outer  row  with  some  larger 
ones.  A  row  of  short,  weak  teeth  on  the  palatines;  head  of  vomer  with  a  short  fang  on 
either  side.  Eye  moderate;  gill  openings  very  wide,  the  membranes  free  from  the  isthmus. 
Gill  rakers  not  very  numerous,  rather  short  and  stout.  Pseudobranchiae  none.  Branchi- 
ostegals  numerous,  11.  No  air  bladder.  Dorsal  and  anal  well  developed,  the  former  far  in 
advance,  its  posterior  rays  over  the  origin  of  anal.   No  adipose  fin.   Caudal  moderately  forked. 

This  genus  is  in  several  respects  intermediate  between  Gonostoma  and  Photichthys.  It 
is  named  in  honor  of  William  Yarrell,  F.  L.  8.,  (1789-1856),  the  English  ichthyologist. 

YARRELLA  BLACKFORDI,  Goode  and  Bean,  n.  s.     (Figure  121.) 

Body  elongate,  its  greatest  depth  equal  to  length  of  head  without  snout,  and  contained 
74  times  in  the  total  (without  caudal).  Length  of  head  4A  times  in  total  (without  caudal). 
Eye  moderate,  its  diameter  two-thirds  length  of  snout,  and  contained  7  times  in  length  of 
head.  The  maxillary  extends  far  behind  the  ej  e,  its  length  equal  to  that  of  the  postorbital 
part  of  the  head.  Length  of  intermaxillary  nearly  two  tilths  length  of  head.  Teeth  as 
described  under  genus.  Gill  rakers  G  above  and  13  below  the  angle  of  the  first  arch.  1 1n- 
longest  about  as  long  as  the  eye.  Branchiostegals,  14.  Dorsal  origin  a  little  nearer  root 
of  caudal  than  tip  of  snout,  its  origin  nearly  over  the  middle  of  the  space  between  tbe  ven- 
tral and  the  anal  origin,  and  its  posterior  ray  over  the  seventh  ray  of  the  anal;  the  length 
of  its  base  equals  that  of  postorbital  part  of  head:  rays  imperfect,  the  longest  fragment 
remaining  equal  to  longest  of  anal,  and  not  much  more  than  one  third  length  of  head. 
Distance  of  ventral  origin  from  tip  of  snout  contained  2.1  times  in  total  (without  caudal): 
rays  imperfect,  the  longest  only  about  one-fourth  of  length  of  head.  Pectoral  placed  low, 
on  a  narrow  base.  Scales  have  evidently  been  present,  and  of  considerable  size,  but  their 
character  and  number  can  not  be  ascertained. 

Eadial  formula:  D.  15;  A.  ii,  27:   V.  6;  P.  8. 

Color,  purplish  brown;  9  phosphorescent  spots  on  the  isthmus.  25  between  the  sjm-

and  26  from  vent  to  tail.  A  second  row  of  pearly  spots  extends  from  above  root  of  pecto- 
ral to  origin  of  anal. 

This  species  is  dedicated  to  E.  G.  Blackford,  president  of  the  board  of  fish  commis- 
sioners of  the  State  of  New  York,  in  recognition  of  his  services  in  the  promotion  of  ich- 
thyological  studies. 

The  type  of  this  species  was  obtained  by  the  Albatross  from  station  237C, in  29°  03'  15" 
N.  lat.,  88°  16'  W.  Ion.,  at  a  depth  of  324  fathoms.  Two  other  specimens,  the  larger  one  9£ 
inches  in  length,  were  taken  by  the  Albatross  at  the  same  station.

Body  much  elongated,  band-shaped  (covered  with  large  thin  deciduous  scales?).  A 
double  series  of  phosphorescent  organs  runs  along  the  lower  side  of  the  body  and  tail. 
Head  compressed,  with  pointed  snout  and  projecting  lower  jaw.  Mouth  very  wide  but 
slightly  oblique;  jaws  armed  with  small  pointed  teeth  rather  unequal  in  size;  eye  of  mod- 
erate size;  paired  fins  well  developed;  dorsal  fin  in  advance  of  the  anal,  behind  the  ven- 
tral; adipose  fin  none;  anal  very  long.     (Gunther.) 

This  genus  is  represented  by  two  species — the  type,  Diplophos  tcenia,  and  another  from 
the  Pacific,  Diplophos  pacificus  (Challenger  Report),  1.  c.  33.  Both  species  were  obtained 
near  the  surface,  but  their  relations  with  deep-sea  forms  are  very  intimate.

The  length  of  the  head  is  one-sixth  of  the  total  length,  the  greatest  depth  of  the  body 
only  one-sixteenth.  Snout  more  than  twice  as  long  as  the  eye,  pointed,  with  the  lower  jaw 
longest.  The  maxillary  reaches  backwards  tar  behind  the  eye.  Dorsal  fin  short,  its  first 
ray  somewhat  nearer  to  the  end  of  the  snout  than  to  the  root  of  the  caudal;  anal  fin  com- 
mencing below  the  last  dorsal  ray,  and  ending  at  a  short  distance  from  the  caudal.  Paired 
fins  short;  pectoral  inserted  near  to  the  lower  profile;  ventrals  reaching  nearly  to  the  ori- 
gin of  the  dorsal.  The  phosphorescent  organs  are  rounded  black  bodies,  without  silvery 
centre;  they  are  very  numerous  and  arranged  in  two  parallel  series  along  each  side  of  the 
lower  profiles.  Those  of  the  upper  series  are  smaller  than  those  of  the  lower,  are  quite  round 
and  do  not  extend  so  far  towards  the  head  and  the  caudal,  as  the  lower.  The  lower  are  larger 
and  transversely  oblong.  A  pair  of  still  larger  luminous  organs  occupies  a  position  in  front 
of  the  base  of  the  lower  caudal  rays.     Brownish.     (Gunther.)

This  genus  is  closely  allied  to  Gonostoma,  from  which  it  differs  in  the  following  points: 
Both  jaws  are  armed  with  a  single  series  of  teeth,  those  of  the  maxillary  being  small 
and  equal  in  size.  The  intermaxillary  is  armed  with  2  large  fangs  besides  the  small 
teeth;  mandible  with  7  large  equidistant  teeth,  the  spaces  between  them  being  filled 
up  with  very  small  denticles.  Vomer  with  a  fang  on  each  side  of  its  head;  palatine  with 
strong,  curved  teeth,  which  gradually  decrease  in  size  backwards.  The  dorsal  fin  corre- 
sponds in  position  to  the  space  between  ventral  and  anal;  adipose  fin  small.  Air  bladder 
present  as  a  long,  simple  sac  with  thick  walls.     {Hutton,  Giinther.)

34538,  IT.  S.  N.  M.),  the  tye  of  Chauliodus  Meldii,  C.  and  V..  obtained  by  <  'apt.  Field,  in  May, 
1819,  on  a  voyage  from  Mogador  to  New  York,  probably  at  the  surface.  This  specimen 
parsed  from  the  hands  of  Dr.  Mitchill  to  those  of  Mr.  ,1.  ('arson  Brevoort,  then  to  Mr.  E. 
G.  Blackford,  by  whom  it  was  presented  to  the  National  Museum. 

ASTRONESTHKS  GEMMIFEE,  Goode  and  Bean,  n.  s.     (Figure  124.) 

Length  of  head  contained  4i  times  in  the  total  (without  caudal);  its  depth  8  times,  and 
the  depth  of  the  body  5J  times.  Barbel  about  equal  in  length  to  the  head.  Origin  of  the 
dorsal  tin  a  little  nearer  tip  of  snout  than  root  of  caudal;  length  of  its  base  contained 
nearly  4  times  in  the  total  (without  caudal);  its  longest  ray  two  thirds  the  length  of  the 
head.  Ventral  origin  directly  under  the  dorsal  origiu;  length  of  the  ventral  contained  .">i 
times  in  the  total  (without  caudal);  it  does  not  nearly  reach  to  the  vent.  The  distance  of 
the  anal  origin  from  the  root  of  the  caudal  is  a  little  more  than  one-fourth  of  total  length 
(without  caudal).  Eye  longer  than  snout;  one-fourth  as  long  as  the  head.  Pectoral  is 
nearly  one-seventh  as  long  as  body  (without  caudal). 

Radial  formula:  D.  17;  A.  17:  V.  7;  I'.  9. 

The  type  of  this  species  (No.  24045,  U.  S.  N.  M.),  about  7]  inches  in  length,  was  taken 
from  a  halibut's  stomach.  January  26,  1890,  by  the  schooner  Polar  Wave,  in  41  25'  N.  lat., 
53     12'  W.  Ion.     The  halibut  was  taken  in  about  300  fathoms. 

This  species  may  possibly  prove  identical  with  .1.  niger.  The  limits  of  variation  of  the 
lin  rays  in  this  genus  has  not  been  determined  for  lack  of  sufficient  material.  The  species 
has  17  anal  rays  and  numerous  gem-like  dots  on  the  lower  part  of  the  body,  there  being 
about  30  in  the  series  froiu  the  symphysis  of  the  inaudible  to  the  ventral.

Length  of  bead  contained  4|  times  in  total  (without  caudal) ;  its  greatest  depth  nearly 
two-thirds  of  its  length.  Body  slender,  its  height  at  the  dorsal  origin  equal  to  length  of 
postorbital  part  of  head,  and  one-eighth  of  total  length  (without  caudal).  Snout  very  short, 
two-thirds  diameter  of  the  eye,  which  is  contained  nearly  4  times  in  length  of  head.  No 
teeth  on  the  vomer,  and  a  few  scattered  small  teeth  on  the  palatine  bones.  The  origin  of 
dorsal  is  nearer  to  root  of  caudal  than  tip  of  snout.  Length  of  dorsal  base  half  that  of  the 
head;  rays  all  imperfect.  Ventral  origin  immediately  under  the  dorsal  origin;  it  does  not 
nearly  reach  to  the  vent,  and  its  length  equals  that  of  the  postorbital  part  of  the  head. 
Distance  of  anal  origin  from  root  of  caudal  equals  length  of  head.  Length  of  anal  base 
equals  postorbital  part  of  head.  Adipose  fin  directly  over  the  tenth  ray  of  the  anal.

toral and  ventral  fins  very  narrow  and  elongate.  Each  of  the  median  abdominal  series  of 
luminous  spots  contains  54  between  pectoral  and  ventral  fins,  14  between  ventral  and  anal, 
and  15  between  the  origin  of  the  anal  and  caudal.     (Gunther,)

Stomias  boa  was  obtained  by  the  French  expedition  in  eleven  different  localities,  one 
individual  from  each,  at  various  depths  in  the  Gulf  of  Gascogne,  on  the  coasts  of  Portugal 
and  Morocco,  on  the  Banc  d'Arguin,  and  about  the  Cape  Verde  Islands,  at  depths  from  about 
405  to  1,800  meters,  the  greatest  depth  being  in  the  Gulf  of  Gascogne. 

Dr.  Peters  also  identified  this  form  from  the  Pacific.  [Monatsbericht,  Ak.  Wiss.,  Ber- 
lin, 1876,  1846. 

Vaillant  having  examined  a  considerable  amount  of  material,  coincides  with  the  opin- 
ion of  Gunther  that  Stomias  boa  and  Stomias  barbatus  are  identical,  but  reinforces  recent 
opinions  as  to  the  distinctness  of  Stomias ferox,  which  is  well  characterized  by  its  coloration 
and  its  slender  body,  as  well  as  by  the  form  of  the  mandibulary  barbel,  which,  although  it 
is  soft  and  extensible,  so  that  the  characters  derived  from  its  relative  dimensions  are  not  of 
special  value,  has  an  unfringed  tip  which  may  be  regarded  as  a  satisfactory  character, 
although  even  upon  this  question  there  is  some  doubt.

Stomias  affinis,  GiiNTHER,  Challenger  Report,  XXII,  1885,  205,  pi.  liv,  fig.  A. 

Scaleless,  but  with  the  hexagonal  divisions  of  the  skin  distinct.  The  height  of  the  body 
is  one-twelfth  of  the  total  length,  without  caudal,  the  length  of  the  head  one-eighth.  Teeth 
fixed.  The  barbel  is  about  as  long  as  the  head,  and  terminates  in  3  filaments  (fig.  a);  the 
end  of  the  stem  of  the  barbel  white,  with  a  black  pigment  spot,  and  probably  luminous. 
Pectoral  and  ventral  tins  narrow  and  elongate,  especially  the  latter,  which  taper  into  a  fila- 
ment and  extend  beyond  the  anterior  anal  rays.  Anal  tin  higher  than  dorsal.  Each  of  the 
abdominal  series  of  luminous  spots  contains  43  between  the  pectoral  and  ventral  fins,  6 
between  ventrals  and  anal,  and  15  (16)  between  the  origin  of  the  anal  and  caudal;  another 
parallel  series  runs  below,  and  a  third  above  the  middle  of  the  side  of  the  body.  Fins 
white,  dorsal,  anal,  and  ventrals  with  black  margins.     (Gunther.)

Until  in  1879  a  specimen  of  this  species  |  N<>.  22364,  U.  S.  X.  M.),  was  brought  in  by  one 
of  the  Gloucester  fishing  vessels,  this  form  was  known  only  from  Madeira,  where  a  speci- 
men 13|  inches  long  was  taken  in  a  net  close  to  the  shore,  prior  to  1843,  when  it,  was 
described  l>y  Lowe.  Since  1879  numerous  specimens  have  been  obtained:  two  by  the  Tilakr, 
from  Stations  cxxxvi  and  cxxxvii,  in  the  old  Bahama  Channel,  at  a  depth  of  500  fathoms;

ECHIOSTOMA  MARGARITA,  Goode  and  Bean,  n.  a.     (Figure  131.) 

The  length  of  the  individual  to  base  of  the  caudal  is  393  millimeters  (13J  inches).  The 
greatest  depth  of  the  body,  51  millimeters,  equals  the  length  of  the  head  and  is  contained 
nearly  8  times  in  the  total  length.  A  stout  barbel  is  situated  at  a  distance  of  23  millime- 
ters from  the  tip  of  the  lower  jaw;  its  length,  2s  millimeters,  is  somewhat  more  than  one- 
half  the  length  of  the  head;  at  the  extremity  this  barbel  is  divided  into  six  fringes,  one  of 
which  is  whitish;  a  whitish  band  on  the  barbel  near  the  root  of  the  fringes.  Thereare 
about  31  teeth  on  each  side  of  the  maxilla,  and  36  on  each  side  of  the  mandible;  none  of 
the  teeth  in  the  jaws  being  enlarged.  The  vomer  has  a  pair  of  depressible  fangs  on  the 
right  side  and  a  single  one  on  the  left.  There  are  5  depressible  teeth  on  each  palatine.  Lin- 
gual teeth  in  about  four  rows.  The  largest  teeth  in  the  jaws  are  scarcely  more  than  2  mil- 
limeters long. 

The  length  of  the  upper  jaw,  40  millimeters,  is  four-fifths  the  length  of  the  head.  The 
mandible,  48  millimeters,  is  nearly  as  long  as  the  head.  The  diameter  of  the  eye,  8  milli- 
meters, equals  the  length  of  the  snout  and  is  one-fifth  as  long  as  the  upper  jaw.  The  man 
dible  projects  beyond  the  upper  jaw  when  the  mouth  is  closed  a  distance  equal  to  one-half 
the  length  of  the  eye.  Nostrils  about  midway  between  the  eye  and  the  tip  of  the  snout. 
The  gill  lamina)  are  all  well  developed  and  increase  in  size  backwards,  not  entirely  con- 
cealed by  the  opercular  bones.     The  gill  rakers  consist  of  minute  scattered  spines. 

The  distance  of  the  vent  from  the  base  of  the  caudal,  04  millimeters,  is  contained  0' 
times  in  the  total  length.  The  anal  begins  immediately  behind  the  vent  and  extends  nearly 
to  the  base  of  the  tail.  The  dorsal  is  immediately  over  the  anal.  The  origin  of  the  ventral 
is  211  millimeters  from  the  tip  of  the  snout  and  109  millimeters  from  the  base  of  the  caudal. 
The  sixth  and  longest  ray  of  the  ventral,  4:;  millimeters,  is  five-sixths  the  length  of  the  head. 
The  pectorals  of  both  sides  have  been  torn  off.  Two  rows  of  minute  phosphorescent  dots 
similar  to  those  in  E.  barbatum  and  similarly  situated.  A  pearl  colored  spot  above  the 
maxilla,  beginning  at  the  hind  margin  of  the  eye;  its  length  about  two  thirds  that  of  the  eye; 

Radial  formula:  I).  18;  A.24;  V.  7:  P.O.

On  the  13th  of  March,  1885,  the  steamer  Albatross  trawled  a  large  specimen  of  Echio- 
stoma  at  station  2394,  X.  lat.  28° 38' 30",  \Y.  Ion.  87°02',in420  fathoms  (U.  S.  Nat.  Mus.,No.

Opostomias,  Gt'NTHER,  Challenger   Report,    XXII,  238  (type,  0.  micripiuis,  GCNTHER,   loc.  cit.,  208,  pi.  mi, 
fig.  A). 

A  genus  of  stomiatoid  fishes,  closely  allied  to  Echiostoma,  but  differing  in  dentition, 
the  jaws  aimed  with  few  strong,  nondepressible  teeth,  received  in  deep  hollows  in  the  oppo- 
site jaws.  Maxillaries  and  palatines  toothless.  Pectoral  with  separate  ray.  Body  naked. 
An  immense  number  of  luminous  organs. 

This  genus  is  known  from  a  single  specimen,  loi  inches  long,  captured  by  the  Challen- 
ger south  of  Australia,  at  a  depth  of  2,150  fathoms,  described  by  Gunther  as  Echiostoma 
micrijmtis.    (Fig.  132.) 

5RAMMATOSTOMIAS,  Goode  and  Bean,  n.  g. 

Similar  in  general  appearance  to  Echiostoma.  Head  short,  compressed.  Body  com- 
pressed, moderately  elongate.  Dorsal  and  anal  with  numerous  rays,  placed  opposite  each 
other  and  close  to  the  root  of  the  caudal.  Ventrals  in  advance  of  the  middle  of  the  body, 
at  a  great  distance  from  the  vent.  Pectorals  placed  near  the  abdominal  outline,  consisting 
of  a  short  filament  very  slightly  separated  from  the  rest  of  the  fin,  and  several  rays  con- 
nected by  a  membrane.  Two  rows  of  minute  phosphorescent  spots  on  the  body  similar  to 
those  in  Echiostoma.  A  very  long  and  slender  hyoid  barbel.  Mandibular  teeth  very 
unequal  in  size,  comparatively  few  in  number,  arranged  in  two  rows,  an  outer  row  of  fixed 
teeth  and  an  inner  row  of  depressible  ones.  The  first  pair,  near  the  tip  of  the  mandible,  is 
very  greatly  enlarged  and  passes  outside  of  the  upper  jaw  when  the  mouth  is  closed.  Inter- 
maxillary teeth  uniserial  or  nearly  so,  the  edge  of  the  bone  posteriorly  with  minute  cirri. 
A  pair  of  small,  fixed,  curved  fangs  in  front,  followed  by  a  pair  of  larger  movable  ones. 
Vomer  toothless.  Palatines  with  several  weak  teeth.  No  lingual  teeth.  Upper  pharyn- 
gals  present.  A  pearl-colored  spot  on  the  cheek,  similar  to  that  in  Echiostoma.  Four 
gills;  a  short,  narrow  slit  behind  the  fourth.  Gill  rakers  not  numerous,  short,  spine-like. 
Gill  lamina1  increase  in  size  backwards.  A  series  of  pigment  cells  along  the  median  line  of 
the  body,  so  arranged  as  to  simulate  a  lateral  line.  Eye  small,  Caudal  lobes  apparently 
unequal.  Skin  naked,  its  whole  surface  sprinkled  with  minute  raised  pigment  spots,  each 
with  a  light  center. 

GRAMMATOSTOMIAS  DENTATUS,  Goode  and  Bean,  n.  s.    (Figure  133.) 

The  greatest  height  of  the  body  equals  the  length  of  the  head  without  the  snout  and  is 
one-seventh  of  the  total  length  without  caudal.  The  maxilla  is  long  and  slender;  its  length 
is  contained  6£  times  in  the  total.  The  length  of  the  mandible  is  contained  5|  times  in  the 
total.  The  eye  is  as  long  as  the  snout,  about  one-fifth  as  long  as  the  head.  The  nostrils 
are  a  little  nearer  to  the  eye  than  to  the  tip  of  the  snout.  The  anterior  nostril  is  placed 
nearly  in  front  of  the  middle  of  the  eye  in  a  very  short  tube ;  the  posterior  is  on  a  level  with 
the  top  of  the  eye  and  is  merely  a  small  slit.  The  supramaxillary  and  intermaxillary  are 
closely  welded,  but  their  separation  is  marked  by  a  changing  in  the  character  of  the  teeth; 
those  on  the  supramaxillary  being  minute  cirri.  The  large  fangs  in  the  tip  of  the  mandible 
are  two-sevenths  of  the  length  of  the  upper  jaw. 

The  hyoid  barbel  is  placed  at  a  distance  from  the  symphysis  of  the  mandible,  which  is 
about  equal  to  the  enlarged  fangs  of  the  mandible,  or  one-fifth  of  the  length  of  the  mandi- 
ble. The  length  of  the  barbel  is  nearly  one-third  of  the  total.  The  pectoral  is  situated  close 
behind  the  head  and  near  the  ventral  outline;  its  first  ray  is  distinct  from  the  other  three, 
although  placed  close  to  them,  and  is  not  produced.  The  greatest  length  of  the  pectoral  is 
about  one-fourth  that  of  the  head.  The  ventrals  are  placed  in  advance  of  tin1  middle  of 
the  total  length,  their  distance  from  the  origin  of  the  pectorals  being  one-half  as  great  as

from  the  caudal  base.  The  fourth  and  longest  ray  nearly  equals  the  greatest  Height  of  the 
body.    The  distance  of  the  dorsal  origin  from  the  caudal  base  is  contained  5|  timesinthe 

total  length.  The  longest  dorsal  ray,  which  is  in  the  middle  of  the  tin.  is  one-half  as  long  as 
the  longest  of  the  ventral  rays.  The  length  of  the  dorsal  base  is  contained  0'  times  in  the 
total  length.  The  base  of  the  anal  is  slight  ly  longer  than  that  of  the  dorsal,  and  its  longest 
ray  is  about  three-fourths  as  long  as  the  longest  dorsal  ray.  The  caudal  lobes  in  the  only 
specimen  available  for  study  are  unequal,  the  lower  one  being  much  longer  than  the  upper, 
but  this  may  be  the  result  of  accident.  There  are  two  rows  of  luminous  spots,  one  close  to 
the  ventral  outline,  which  becomes  obsolete  before  it  reaches  the  origin  of  the  anal,  and 
another  in  the  lower  third  of  the  height  of  the  body,  which  becomes  indistinct  about  the 
middle  of  the  total  length;  14  of  these  spots  between  the  pectoral  and  the  ventral  in  the 
lower  series  and  11  in  the  upper  series.

Eustomias  obscurus,  Vaillant,  Exp.  Sci.  Travailleur  et  Talisman,  113,  pi.  Ill,  figs.  3,  3a. 

Body  elongate:  height  scarcely  one-twentieth  of  length,  and  thickness  one  thirtieth. 

The  head,  whose  length  is  one-seventh  of  the  length  of  the  body,  is  conical,  compressed; 
the  lower  jaw  projects  beyond  the  upper:  the  snout  half  the  length  of  the  head:  mouth 
very  large,  although  the  maxillary  does  not  extend  far  behind  the  orbit:  the  intermaxillary 
has  2  long,  fang  like  teeth,  and  11  others  less  conspicuous  but  strong;  the  tirst  and  the 
fifth  in  the  latter  series  are  the  strongest,  the  last  the  smallest.  On  the  maxillary  the 
teeth  are  visible  only  with  the  aid  of  a  magnifying  glass;  the  teeth  upon  the  mandibles  are

similar  to  those  upon  the  maxillaries,  and  are  14  in  number  on  either  side;  the  first  two, 
separated  from  the  following  by  an  interval,  are  the  strongest;  the  third,  sixth,  tenth,  and 
eleventh  are  also  conspicuous;  the  others,  although  shorter,  are  very  robust;  no  teeth 
upon  the  palatines;  fangs  upon  the  tongue  as  strong  as  those  in  the  jaws,  1  in  front  and 

2  or  3  behind  it.  Diameter  of  the  eye  11  times  in  the  length  of  the  head,  interorbital 
space  slightly  less;  length  of  barbel  twice  that  of  head,  cylindrical,  fringed  at  each  end 
with  7  long  threads,  at  the  end  of  each  of  which  is  a  small  ball.  Branchial  opening  broad ; 
branchiostegal  membrane  supported  by  short  rays,  between  which  are  luminous  dots;  a 
small  luminous  body,  conspicuous  on  account  of  its  light  color,  under  the  eye.  Body  abso- 
lutely scaleless,  with  numerous  little,  white,  luminous  dots  in  double  series  on  each  side  of 
the  belly;  vent  far  back,  distance  frcm  the  snout  equal  to  seven-tenths  of  length  of  body. 

Dorsal  and  anal  extend  nearly  to  the  base  of  the  caudal;  the  length  of  the  anal  is  one-

Photonectea,  Gcxther,  Challenger  Report,  xxu,  1887,  212  (Type,  Lucifer  albipinnis,  Doderlein,  from  Inosima). 

Body  compressed,  rather  long,  scaleless;  vent  far  behind  the  middle  of  the  length. 
Head  compressed,  with  short  snout  and  exceedingly  wide  mouth.  Teeth  in  the  jaws  small, 
unequal  in  size,  in  single  series;  vomer  and  palatine  with  a  small  group  of  teeth  on  each 
side.  Eye  small.  Opercular  portion  of  the  head  very  narrow.  A  long  hyoid  barbel.  The 
dorsal  fin  opposite  the  anal,  which  commences  behind  the  vent.  Pectorals  none.  Ventrals 
inserted  behind  the  middle  of  the  length.  A  small  suborbital  phosphorescent  organ,  and 
two  series  of  luminous  dots  along  the  lower  part  of  the  sides,  with  numerous  rudimentary 
similar  organs  scattered  over  the  skin  of  the  body.     (Giinther.) 

Photonectes  (=Lucifer,  Doderlein)  has  been  known  heretofore  from  a  single  species,  P. 
albipinnis,  taken  at  Inosima,  Japan. 

PHOTONECTES  GRACILIS,  Goode  and  Bean,  n.  8.    (Figure  137.) 

A  species  much  more  slender  than  P.  albipinnis.  The  type  of  this  description  is  in 
very  poor  condition;  the  hyoid  barbel  is  remarkably  short  and  is  probably  imperfect.  The 
fins,  also,  are  incomplete,  and  the  luminous  dots  along  the  sides  are  so  indistinct  as  to  be 
made  out  only  with  great  difficulty.  Its  length,  without  including  caudal,  is  170  milli- 
meters. The  greatest  height  of  the  body  (11  millimeters)  is  contained  15£  times  in  the 
length  without  caudal.  The  least  height  of  the  tail  (2  millimeters)  is  nearly  one-fifth  of  the 
height  of  the  body.  The  greatest  depth  of  the  head  (12  millimeters)  equals  the  length  of 
its  postorbital  portion.  The  snout  is  very  short,  nearly  one-half  as  long  as  the  eye.  The 
posterior  nostril  is  immediately  in  front  of  the  eye,  and  the  anterior  is  near  the  end  of  the 
snout  and  a  little  below  the  level  of  the  posterior.  Both  are  subcircular  or  oblong  in  shape, 
and  the  posterior  has  a  small,  narrow  flap.  The  diameter  of  the  eye  (5  millimeters)  is 
one-fourth  the  length  of  the  head  (20  millimeters).  Below  and  behind  the  eye  there  is  a 
luminous  body,  which  is  nearly  as  long  as  the  eye  and  somewhat  club  shaped.  At  the  mar- 
gin of  the  operculum  there  is  a  small,  roundish,  luminous  dot.  The  maxilla  is  a  very  thin 
and  narrow  bone  extending  backward  almost  to  the  end  of  the  head;  it  is  very  slightly 
curved  and  forms  a  very  obtuse  angle  with  the  short  intermaxilla.  The  mandible  is  very 
strongly  curved  upward,  resembling  a  sled  runner;  its  length  (22  millimeters)  equals  twice 
the  greatest  height  of  the  body.    Both  jaws  are  armed  with  numerous  fine  teeth  of  unequal

size;  only  .1  remain  on  each  side  of  the  intermaxilla.    Tbe  maxilla  has  20  true  teeth  on  its 

anterior  half,  and  the  posterior  half  has  about  1»>  seme.  There  are  about  35  teeth  <>n  each 
side  of  the  inaudible.  All  the  teeth  of  the  jaws  rake  inward  and  backward,  and  are 
depressible.  Three  teeth  on  each  side  of  the  head  of  the  vomer,  increasing  in  size  back- 
wards.   A  pair  of  teeth  on  each  palatine  bone.    One  fang  near  the  tip  of  the  tongue  and 

3  farther  back.  Four  gills,  a  small  slit  behind  tin'  fourth.  The  gill  laminae  not  well  cov- 
ered by  the  operculum.  Gfll  rakers  verj  few,  minute,  ami  spine  like.  Gill  openingvery 
wide,  the  membrane  cleft  almost  down  to  the  origin  of  the  hyoid  barbel.  No  pseudo- 
branchiae.  The  hyoid  barbel  is  situated  nearly  under  the  tip  of  the  tongue;  it  is  evidently 
imperfect,  its  length  being  scarcely  one  half  that  of  the  eye. 

The  length  of  the  bead  (20  millimeters)  is  contained  8.1  times  in  length  to  base  of  cau- 
dal. The  origin  of  the  dorsal  is  at  a  distance  from  the  caudal  base  (11  millimeters),  a  little 
more  than  one-fourth  of  the  standard  length.  The  length  of  the  dorsal  base  (34  milli- 
meters) is  one-fifth  of  the  standard  length.  The  longest  dorsal  ray  is  a  little  longer  than 
the  eye. 

The  anal  begins  immediately  under  the  dorsal,  and  its  base  is  slightly  longer  than  that 
of  the  dorsal;  its  rays  are  about  as  long  as  those  of  the  dorsal.  The  distance  from  the  end 
of  the  anal  to  the  origin  of  the  middle  caudal  rays  (10  millimeters)  equals  one  half  the 
length  of  the  head.  The  distance  of  the  ventral  from  the  tip  of  the  snout  (87  millimeters) 
is  a  little  more  than  one-half  of  the  standard  length;  consequently  the  origin  of  the 
ventral  is  very  slightly  nearer  to  the  root  of  the  caudal  than  the  tip  of  the  snout.  The 
distance  from  the  origin  of  the  ventral  to  that  of  the  anal  slightly  exceeds  the  length  of 
the  anal  base.     Caudal  and  ventral  imperfect.     Pectoral  wanting. 

Radial  formula:  D.  18;  A.  21;  V.  7;  P.  0. 

Color,  very  dark.  A  row  of  luminous  dots  along  the  margin  of  the  branchiostegal 
membrane;  two  rows  beginning  on  the  isthmus  and  extending  back  along  the  edge  of  the 
belly,  passing  between  the  ventrals  and  slightly  above  the  base  of  the  anal,  disappearing 
near  the  end  of  the  body;  another  row  higher  up  on  the  side,  which  cannot  be  traced  back 
farther  than  the  origin  of  the  ventral,  on  account  of  the  bad  condition  of  the  specimen. 

This  specimen  was  obtained  by  the  steamer  Blake,  at  station  XL,  off  Martinique,  in 
472  fathoms.

Giinther  has  described  a  species  very  closely  related  under  the  name  of  Malacosti  us 
indicus  (Challenger  Report,  xxn,  214,  pi.  irv,  tig.  B.),  from  near  the  Philippines,  500  fath- 
oms, and  in  the  Andaman  Sea  (Alcoch)  650  fathoms.

Malacosteus  choristodaclylus,  Valllant,  Exp.  Sci.  Travailkur  et  Talisman,  xxu,  18ns,  ids,  pi.  viii,  fig.  4. 

A  Malacosteus  with  a  comparatively  stout  body,  its  height  nearly  one-fourth  of  its 
length,  its  thickness  six  one-hundredths  of  same;  with  immense  branchial  opening  by  the 
extent  of  which  the  length  of  the  head  is  seemingly  reduced  to  one-eighth  of  the  length  of 
the  body,  and  with  comparatively  short  dorsal  and  anal  fins  inserted  nearly  opposite  each 
other,  apparently  rounded  and  not  falcate;  caudal  fin  very  small;  luminous  body  under  eye 
subquadrangular,  its  greatest  length  less  than  the  diameter  of  the  eye;  ventrals  longer 
than  base  of  anal,  much  longer  than  base  of  dorsal;  the  longest  ray  apparently  equal  to  the 
distance  from  insertion  of  anal  to  the  end  of  middle  caudal  rays;  length  of  strongest  fangs 
greater  than  diameter  of  eye.  Black,  apparently  without  small  luminous  dots  upon  the 
body. 

Eadial  formula:  D.  19;  A.  20;  C.  12+;  P.  5;  B.  6. 

This  species  was  described  by  Vaillant  from  three  specimens,  two  from  the  coast  of 
Morocco  in  1,400  to  1,635  meters  and  one  from  the  Azores  in  2,220  meters.  The  species  is 
very  distinct  from  M.  niger  and  easily  recognized.

A  genus  allied  to  Malacosteus,  characterized  by  the  absence  of  pectoral  and  adipose 
dorsal  fins,  and  the  absence  also  of  teeth  upon  the  palatines.  The  body  is  compressed,  skiu 
naked;  ventrals  in  advance  of  the  middle  of  the  body;  vent  behind  the  middle  of  the  body; 
opercula  rudimentary.  A  series  of  long,  crooked  teeth  in  the  intermaxillary;  teeth  upon 
the  lingual  and  pharyngeal  bones,  but  absent  upon  the  vomer.  Two  post-orbital  photo- 
phores.  Two  rows  of  photophores  along  the  sides  of  the  belly,  and  a  great  number  of  small 
luminous  points  scattered  over  the  entire  surface  of  the  body.    Type,  P.  Guenii,  Collett.

The  type  of  this  species,  ;i  single  specimen,  a  female  containing  eggs  nearly  mature, 
was  taken  on  the  30th  of  June,  1887,  by  the  Hirondelle,  at  a  depth  of  1,138  meters,  oft 
the  Azores,  in  :;s  34'  30"  N.  Lat.,  30°  43'  30"  W.  bong.  The  species  is  named  in  honor  of

Fishes,  N.  America,  1885,  39. 

Body  elongate,  compressed,  scaleless;  head  compressed;  snout  produced ;  mouth  cleft 
wide;  premaxillary  long  and  slender;  maxillary  thin,  long,  immovable.  Teeth  unequal, 
immovable.  Very  small  teeth  run  along  entire  length  of  intermaxillary.  Palatine  teeth 
compressed,  pointed,  the  two  or  three  anterior  ones  very  strong  and  long,  and  the  pos- 
terior ones  moderate.  Teeth  in  lower  jaw  similar  to  those  on  the  palatine  bones,  one 
pair  in  front  and  two  or  three  pairs  in  the  middle  much  enlarged.  Eye  large.  Pectoral 
and  ventral  tins  well  developed.  Adipose  fin  of  moderate  size.  Caudal  forked.  Gill  opening 
very  wide.     Branchiostegals,  v-vn. 

The  name  Plagyodus,  Steller  (Pallas,  Zoogr.  Ross.  Asiat.,  Ill,  383),  has  been  adopted  by 
Dr.  Gunther,*  but  it  is  doubtful  whether  Steller  used  the  name  Plagyodus  in  the  sense  of  a 
Linnaean  genus. 

The  following  discussion  of  this  genus  is  quoted  from  Gunther's  great  work: 

"Like  most  other  deep-sea  fishes,  Alepidosaurus  has  been  found  at  widely  distant  local- 
ities, and  it  is  probable  that  in  time  it  will  be  obtained  in  tlie  intermediate  parts  of  the 
ocean.  Deep-sea  fishes  are  much  less  subject  to  differences  of  climate  than  those  inhabit- 
ing the  coasts  or  the  surface,  and  therefore  we  should  not  be  surprised  to  find  the  repre- 
sentatives of  one  aad  the  same  genus,  and  frequently  even  the  same  species,  in  high  lati- 
tudes of  the  northern  and  southern  hemispheres. 

"Every  part  of  the  Alepidosauri  is  so  fragile  that  it  is  extremely  difficult  to  obtain 
perfect  specimens.  It  is  also  impossible  to  preserve  them  in  spirits  without  some  portion 
of  the  dorsal  and  of  the  other  fins  being  broken.  The  entire  structure  of  the  dorsal  fin  is 
so  delicate,  that  it  must  even  be  liable  to  injury  and  alteration  of  outline  while  the  fish  is 
in  its  native  element.  The  fibrous  ligaments  connecting  the  vertebra  are  very  loose  and 
extensible,  so  that  the  form  of  the  fish  is  easily  lengthened  when  its  body  is  slightly 
stretched.  Therefore  no  reliance  whatever  is  to  be  placed  on  trivial  specific  distinctions 
founded  on  the  form  of  the  dorsal  fin  and  on  the  relative  proportions  of  the  head  and  body. 
A  comparison  of  the  two  figures  of  A.  ferox,  given  by  Lowe,  will  show  the  truth  of  this 
observation. 

"The  loose  connection  of  the  single  parts  of  the  body  is  found  in  numerous  deep  sea 
fishes,  and  is  merely  the  consequence  of  their  withdrawal  from  the  pressure  of  the  water  to 
which  they  are  exposed  in  the  depths  inhabited  by  them.  When  within  the  limits  of  their 
natural  haunts,  the  osseous,  muscular,  and  fibrous  parts  of  the  body  will  have  that  solidity 
which  is  required  for  the  rapid  and  powerful  movements  of  a  predatory  fish.  That  the 
fishes  of  this  genus  belong  to  the  most  ferocious  of  the  class  is  proved  by  the  dentition  and 
the  contents  of  their  stomach;  but  it  is  worthy  of  notice  that  although  the  mouth  is  so 
deeply  cleft,  the  lower  jaw  can  not  be  moved  from  the  upper  at  a  greater  angle  than  about 
40  degrees.  The  teeth  are  constantly  changing  and  it  is  odd  that  an  ichthyologist  like 
Lowe  should  have  had  so  much  difficulty  in  recognizing  the  nature  of  some  immature  teeth 
lying  in  the  gingiva." 

P.  Poey  has  described  a  specimen  from  Cuba,  under  the  name  of  A.  altivelis  (Poey, 
Mem.  Hist.  Nat.  Cuba,  II,  302),  and  also  referred  to  another  form,  which  Gill  has  named 
provisionally  Gaulopus  Poeyi  (Proc.  Acad.  Nat.  Sci.,  Philad.,  1802,  p.  131).

DISCUSSION    ()F    SPECIES    AND    THEIB    DISTRIBUTION.  117 

Gill  has  also  described  a  species  from  the  Pacific  coast  of  North  America,  under  the 
name  of  Gaulopus  borealis  (Proc.  Acad.  Nat.  Sri.,  Philad.,  1862,  p.  L28);  and  Beau  another, 
Alepisaurus  cesculapius  (Proc.  U.  S.  Hat.  Mus.,  1883,  .'501);  and  there  is  also  die  doubtful 
Caulopus  serra  of  Gill  from  .Monterey,  California. 

We  are  not  thoroughly  satisfied  that  more  than  one  species  has  been  found  in  the 
Atlantic.

Length  of  the  head  is  less  than  twice  the  height  of  the  body,  aud  rather  less  than  one- 
si  sth  of  the  total.  Eye  median,  contained."*  to  6  times  in  length  of  head,  as  wide  as  the  inter- 
orbital  space.  Dorsal  fin  much  elevated;  pectorals  elongated,  equal  in  length  to  the  head, 
hut  reaching  nearly  two-thirds  of  the  distance  to  the  insertions  of  the  ventrals;  first  rays  of 
dorsal,  pectoral,  and  ventral  serrated. 

Radial  formula:  D.38-44;  A. 14-17;  P.14-15;  V.  0-10. 

A.  ferox  was  first  described  from  specimens  obtained  by  Lowe  in  the  deep  waters  near 
Madeira.  In  addition  to  Lowe's  types,  and  a  few  other  specimens  obtained  by  the  Madeira 
fishermen  upon  tue  deep-sea  lines,  the  species  appears  not  to  have  been  captured,  except  in 
the  Western  Atlantic. 

From  the  Western  Atlantic  specimens  have  been  sent  to  the  National  Museum.  Of 
three  of  these  the  locality  is  not  known,  but  they  were  obtained  in  the  New  York  markets 
by  Mr.  E.  G.  Blackford,  and  forwarded  to  Washington  by  him.  The  Albatross  obtained 
one  at  the  surface  (Cat.  No.  25202  U.  S.  N.  M.)  in  Uo  30'  X.  Lat.,  57°  13'  W.  Long.,  and 
another  (Oat,  22292  (J.  S.  N.  M.)  at  a  depth  of  105  fathoms  in  42°  4.V  K  Lat.,  63°  W.  Long. 
The  Gloucester  fishermen  obtained  two  on  Le  Have  Lank,  one  (No.  24245)  at  275  fathoms, 
another  (No.  L'4244)  at  120  fathoms;  also,  two  others  (Nos.  24296  ami  L'HiOT)  in  200  fathoms 
at  Lat.  42°  37' K,  Lon.  62°  55' W.,  and  another  (No.  24243)  in  Lat.  43°  46'  IS.,  Lon.  61° 
is'  w.  in  200  fathoms.  A  skull  of  Alepisaurus,  from  Van  Diemen's  Land,  preserved  in  the 
British  Museum,  has  been  provisionally  identified  by  Gunther  with  those  species,  but  it- 
seems  scarcely  safe  to  regard  A.  ferox  as  an  inhabitant  of  the  Australian  seas  until  more 
material  has  been  obtained  for  study. 

A  closely  allied  species,  with  somewhat  shorter  paired  tins,  has  been  described  by  Dr. 
Bean  under  the  name  of  A.  ceseulapius.  The  fish  was  speared  at  Unalaska  in  October.  L880, 
just  as  it  was  swimming  upon  the  beach.  It  undoubtedly  had  come  to  I  lie  surface  from  the 
deep  adjacent  to  Captains  Harbor,  where  it  was  captured.  The  hundred-fathom  line 
at  this  point  approaches  rather  close  to  the  shore.  This  individual  had  in  its  stomach  twenty- 
one  individuals  of  the  spiny  lumpfish.  It  was  Dr.  Bean's  opinion  that  it  had  been  driven 
ashore  by  the  torture  of  a  parasitic  worm  found  in  its  flesh.  The  "Wolf  Fish",  as  it  is 
called  in  this  region,  frequently  is  stranded  on  the  beach  at  lliuliuk.

Alepidosaunis  altivells,  Guktther,  loc.  cit.,  and  in  Challenger  Report,  xxn,  203. 

Length  of  the  head  is  more  than  twice  the  height  of  the  body,  and  contained  6^  times 
in  the  total  (with  the  caudal).  Dorsal  fin  much  elevated;  pectoral  elongate,  but  terminat-

lobes  equal  in  length. 

Radial  formula:  D.  40;  A.  17;  P.  16;  V.  13. 

The  type  of  this  species  was  about  3  feet  long,  and  was  obtained  by  Cuban  fishermen 
at  a  great  depth.  Poey  had  another  form,  somewhat  different,  since  described  by  Gill 
under  the  name  Caulopus  PoeyL*

Body  elongate,  somewhat  compressed,  formed  much  as  in  a  Barracuda,  covered  with 
cycloid  scales  of  moderate  or  rather  large  size.  Head  long,  usually  scaly  on  the  sides. 
Mouth  very  large,  lower  jaw  projecting.  Premaxillary  not  projectile,  very  long  and  slender, 
forming  the  entire  margin  of  the  upper  jaw.  Maxillary  long  and  slender,  closely  adherent 
to  the  premaxillary.  Teeth  rather  strong,  pointed,  in  single  series  on  the  jaws  and  pala- 
tines; some  of  them  on  lower  jaw  and  palatines  sometimes  very  long  and  fang  like,  and 
most  of  them  freely  depressible.  Opercular  bones  thin.  Pseudobranchise  present.  Gill 
membranes  separate,  free  from  the  isthmus.  Branchiostegals,  about  7.  Gill  rakers  short, 
sharp,  spine-like.  Eye  large.  Lateral  line  present,  its  scales  usually  enlarged.  Dorsal  fin 
short  and  small,  behind  the  middle  of  the  body,  nearly  or  quite  over  the  ventrals.  Adipose 
fin  present;  anal  fin  low,  rather  long;  caudal  fin  short,  narrow,  forked;  pectorals  rather 
small,  placed  low.  Pyloric  csecauone.  No  air  bladder.  Phosphorescent  spots  few  or  none. 
(Jordan.) 

In  this  family  are  at  present  included  six  or  more  supposed  species  of  pelagic  fishes  of 
small  size,  which  are  believed  to  occur  only  in  the  deep  waters  of  the  Atlantic  and  Pacific, 
which  in  structure  recall  to  mind  the  genus  Ahpocephalus,  but  which  in  general  appearance 
are  more  like  Sphyrcena.    There  are  two  groups. 

Those  of  the  Sudis  type,  which  is  distinguished  by  the  presence  of  three  or  five  very 
long,  fang-like  teeth  on  each  side  of  the  lower  jaw,  has  not  yet  been  found  in  the  Atlantic 
Basin  itself.  Sudis  hyalina  of  Risso  has  long  been  known  from  the  Mediterranean.  S.  ringens 
of  Jordan  and  Gilbert  was  collected  by  Jordan  in  1880  in  the  Santa  Barbara  Channel,  Cal- 
ifornia. 

The  Paralepis  type  is  represented  by  four  species :  one,  P.coregonoides,  from  the  Mediter- 
ranean, P.  sphyrcenoides,  from  the  Mediterranean  and  also  from  Madeira;  one,  P.  borealis, 
from  the  Arctic  waters  of  North  America,  from  the  Gulf  of  St.  Lawrence  northward,  and 
one,  P.  coruscans,  very  similar  to  the  latter,  and  found  under  similar  conditions  in  Puget 
Sound.  It  is  probable  that  with  more  material  the  number  of  species  may  be  considerably 
lessened.  There  are  two  species  described  from  Nice  which  we  have  not  been  able  to  study, 
viz.,  P.  Cuvieri,  Bonaparte,  and  P.  speciosus,  Bellotti.    The  types  of  the  latter  are  said  to  be 

in  Milan.

Body  elongate  and  much  compressed  posteriorily;  its  height  is  contained  6  to  G£  times 
in  its  total  length  (without  caudal);  the  length  of  the  head  44  times.  The  wide  cleft  of  the 
mouth,  which  is  oblique,  extends  far  beyond  the  eye,  but  docs  not  reach  the  angle  of  the

122  DEEP-SEA    FISHES   OF   THE    ATLANTIC    BASIN. 

This  species  is  known  only  from  the  Mediterranean,  where  it  is  very  rare.  The  National 
Museum  has  a  specimen  (No.  40054,  U.  S.  N.  31.)  from  Nice,  presented  by  the  Royal  Museum 
at  Floreuce,  which  corresponds  perfectly  to  Gunther's  description  and  figure,  and  also  to 
those  of  Risso  and  Valenciennes.  Canestrini  appears  to  have  seen  a  dift'ereut  type,  which 
he  described  as  having  the  dorsal  one-half  as  long  as  the  anal,  instead  of  one-third  (D.  14; 
A.  28).    It  is  not  impossible  that  this  was  another  specific  form. 

OMOSUDIS,  Gunther. 

Omoeudis,  GWnther,  Challenger  Report,  xxn,  1887,  201. 

Body  oblong,  compressed,  naked;  head  compressed;  snout  of  moderate  length;  cleft  of 
month  very  wide;  intermaxillary  and  maxillary  bones  slender,  the  former  with  a  series  of 
very  small  teeth  of  equal  size,  only  one  or  two  anterior  ones  being  somewhat  enlarged;  the 
lower  jaw,  the  vomer,  and  palatine  bones  with  a  few  very  large  and  lanceolate  teeth.  Lower 
jaw  broad,  and,  like  the  rest  of  the  head,  formed  of  very  thin  bone.  The  supraclavicle  and 
post  clavicles  form  a  long  rod  extending  from  the  occiput  on  each  side  downwards  to  the 
abdomen,  and  partly  free,  not  covered  by  skin.  Ventral  fins  inserted  far  behind  the  pecto- 
rals, below  the  origin  of  the  dorsal.  Dorsal  fin  behind  the  middle  of  the  length  of  the  body; 
adipose  fin  very  small;  anal  fin  long.  Stomach  very  distensible.  Branchiostegals,  8;  pseu- 
dobranchise  well  developed ;  gills  4,  with  broad  gill  laminae  and  very  short  gill  rakers.

Omosudis  Lowii,  GONTHER,  Challenger  Report,  xxn,  201,  pi.  lii,  figs,  c,  c". 

The  length  of  the  head  is  two  sevenths  of  the  total  length  (without  caudal);  the 
greatest  depth  of  the  body  immediately  behind  the  head  is  one-fifth  of  the  total  length.  The 
head  is  strongly  compressed,  with  rather  flat  upper  surface ;  snout  somewhat  pointed,  rather 
longer  than  the  eye,  the  diameter  of  which  is  one-third  of  the  length  of  the  head.  The 
bones  of  the  head  are  extremely  thin,  the  operculum  being  smaller  than  the  suboperculum, 
and  separated  by  two  or  three  ridges.  The  infraorbital  ring  is  nearly  membranaceous. 
Preoperculum  terminating  below  in  a  forked  point.  Cleft  of  the  mouth  extending  back- 
wards to  the  angle  of  the  preoperculum. 

The  dentition  is  truly  formidable  for  so  small  a  fish;  the  longest  tooth  is  one  anteriorly 
on  the  side  of  the  mandible;  in  the  British  Museum  specimens,  only  one  is  present  either 
on  the  right  or  left  of  the  jaw;  its  length  is  nearly  one-third  of  that  of  the  head.  The  next 
largest  are  those  on  the  palate,  where  there  are  two  on  each  side,  besides  several  smaller 
ones.  Smaller  teeth  are  also  implanted  on  the  hinder  part  of  the  dentary  bone.  All  the 
large  teeth  can  be  laid  backwards. 

A  semicircular  scale  like,  osseous  lamella  of  extreme,  thinness  covers  the  lower  part 
of  the  cheek,  and  is  marked  by  very  shallow,  concentric  striae. 

The  singular  bone  which  supports  the  side  of  the  anterior  part  of  the  abdomen  is 
styliform,  slightly  curved  backwards.  It  starts  from  the  top  of  the  occiput  and  descends 
tow  aids  the  median  line  of  the  abdomen,  which  it  reaches  behind  the  pectoral  fin.  It  is 
composed  of  the  two  pronged  supraclavicle.  which  is  fixed  by  ligaments  to  the  occiput,  and 
of  three  slender,  needle-shaped  postclavicles;  the  uppermost  postclavicle  is  suspended  by 
ligaments  from  the  supraclavicle,  as  is  also  the  clavicle.  The  rod  lies  immediately  below 
the  thin  integument,  and  its  lower  portion  is  quite  free. 

The  dorsal  fin  commences  midway  between  the  root  of  the  caudal  and  the  eye,  and  is 
composed  of  very  feeble  rays ;  the  anal  commences  at  some  distance  behind  the  dorsal  and 
terminates  not  very  far  from  the  caudal.  Caudal  fin  small,  with  a  considerable  number  of 
basal  rays  above  and  below.  Pectoral  fins  quite  at  the  lower  side  of  the  body;  ventral  fins 
very  small  and  partly  coalescent. 

Light  brownish  on  the  back,  with  numerous  brown  pigment  spots  on  the  sides;  abdo- 
men black.    ( G  ii  n  th  er. )

had  previously  obtained,  in  1868,  the  specimen  collected  by  Lowe  at  Magdalena.  The 
Albatross  obtained  a  single  specimen  from  station  2392,  in  28°  47' 30"  28.  lat.,  87°  27'  W. 
Ion.,  at  a  depth  of  724  fathoms. 

The  capacity  of  this  form  for  swallowing  fishes  greater  in  size  than  itself  appears  to  be 
as  great  as  that  of  Chiasmodus,  as  may  be  understood  from  an  inspection  of  figure  c1  in 
Giinther.

Body  much  elevated  and  compressed,  passing  abruptly  into  a  short  and  compressed 
tail,  the  angle  inade  by  the  hind  margin  of  the  trunk  and  the  lower  edge  of  the  tail  being 
tilled  up  by  a  broad  fold  of  the  integument,  of  peculiar  transparent  appearance,  resembling 
thin  cartilage.  This  fold  bears  the  anal  fin  and  is  supported  by  interhsemal  rays.  The 
greater  portion  of  the  body  is  scaleless  and  covered  with  a  silvery  pigment,  A  series  of 
luminous  spots  runs  along  the  lower  edge  of  the  abdomen  and  is  separated  from  that  of  the 
other  side  by  a  cartilaginous  fold  occupyingthe  median  line  of  the  abdomen;  another  series 
runs  on  each  side  of  the  isthmus:  a  row  of  three  above  and  behind  the  root  of  the  ventials, 
and  another  row  of  three  above  the  vent.  The  luminous  organs  on  the  lower  part  of  the 
tail  consist  anteriorly  of  a  row  of  four,  of  which  the  first  is  prolonged  along  the  back  as  a 
narrow  band,  terminating  about  the  middle  of  the  depth  of  the  body  in  a  globular  black 
spot  with  a  white  center;  posteriorly  in  front  of  the  caudal  rays  there  is  another  row  of  four 
small  spots.

Pectorals  well  developed,  close  to  the  lower  profile;  ventrals  small;  pelvic  bone  with 
a  bifid  spine  in  front  pointing  forwards.  The  dorsal  fin  occupies  the  middle  of  the  back  and 
consists  of  a  triangular  bony  lamella,  very  thin  in  front,  but  strengthened  along  its  hind 
margin,  and  followed  by  several  rays.  Adipose  fin  absent,  or  represented  by  a  very  low 
membranous  fringe  of  the  dorsal  margin  of  the  tail.  The  anal  fin  is  incompletely  developed, 
extending  from  the  vent  to  the  root  of  the  caudal  tin,  its  rays  being  rudimentary,  widely 
set,  and  scarcely  free.  Caudal  fin  broad  and  forked.  Gill  opening  very  wide,  the  gill  mem- 
brane being  attached  to  the  isthmus.  A  luminous  organ  occupies  the  inner  side  of  the  oper- 
culum close  to  its  end;  another  is  placed  at  the  anterior  end  of  the  ceratohyal,  and,  finally, 
a  very  large  glandular  mass  is  lodged  on  the  upper  edge  of  the  anterior  end  of  the  clavicle. 
GUIs  4;  the  branchial  arches  are  long,  not  angularly  bent,  the  branchial  slits  being  closed 
by  a  membrane  in  their  upper  portion.  Only  a  few  of  the  gill  rakers  are  prolonged,  needle- 
shaped,  and  widely  set,  the  others  being  quite  rudimentary.  Pseudobrauchke  present.

This  grotesquely  shaped  and  interesting  fish  was  first  discovered  in  the  West  Indies  in 
1774  by  Hermann. 

It  was  described  by  him  in  1781  in  the  Xaturforneher.  It  was  next  observed  in  the 
mid-Atlantic  in  August,  1S42,  when  Lowe  obtained  a  specimen  taken  between  Madeira  and 
St.  Marys,  the  southernmost  of  the  Azores,  about  80  miles  to  the  southeast  of  the  latter 
island,  in  a  calm,  smooth  sea.  It  was  among  the  rarest  of  fishes  until  the  time  of  the  Chal- 
lenger, which  upon  its  cruise  around  the  world  obtained  quite  a  number  of  specimens  in  the 
mid-Atlantic,  the  Australian  seas,  and  in  various  places  in  the  South  Pacific,  and  about  the 
same  time  the  vessels  of  the  IT.  S.  Fish  Commission  and  Coast  Survey  began  to  obtain  it  in 
the  western  Atlantic.  The  manner  of  its  occurrence  has  been  very  puzzling.  Although 
two  or  three  specimens  were  obtained  at  the  surface,  they  were  usually  caught  up  in  a 
dredge  or  trawl  from  500  to  2,500  fathoms,  and  the  peculiarities  of  its  distribution  have 
given  rise  to  much  speculation.  A  study  of  the  list  of  specimens  published  in  the  Chal- 
lenger Report  would  seem  to  indicate  that  the  fish  inhabits  all  depths  from  the  surface 
downward.  Dr.  Giinther  is  unable  to  accept  this  as  an  indication  of  that  state  of  affairs, 
and  is  of  the  opinion  that  its  frequent  capture  would  seem  to  be  only  a  proof  of  its  abun- 
dance in  all  t  ropieal  seas  and  of  the  slowness  of  its  movements,  which  prevent  it  from  going 
out  of  the.  dredge  or  net.  He  believes  that  although  ii  and  A  rgyropelecus  are  pelagic  fishes 
which  live  in  shoals,  it  is  possible  that  they  may  descend  to  or  beyond  the  hundred-fathom 
line  during  the  daytime.  Why  during  the  daytime  only  is  hard  to  understand,  and  it 
seems  to  us  perhaps  judicious  to  admit  that  we  do  not  know  the  conditions  of  its  distribu- 
tion as  regards  depth,  and  to  wait  for  further  information  before  forming  any  opinion.  Dr. 
Giinther  has  studied  all  of  the  Challenger's  specimens  carefully  and  has  arranged  them  in 
groups  with  reference  to  the  form  of  the  body. 

The  numerous  specimens  collected  by  the  Challenger  differ  not  inconsiderably  in  the 
shape  of  the  body,  which,  in  some  specimens,  is  much  more  oblique  than  in  others;  in  the 
width  of  the  upper  surface  of  the  head  and  neck,  and,  finally,  in  the  size  of  the  eye,  which  in  a 
specimen  50  millimeters  long  is  8  millimeters  wide,  and  in  another  specimen  of  the  same 


DISCUSSION    OF    SPECIES    AND    THEIR    DISTRIBUTION.  1 2."> 

length  <»nly  7  millimeters.     Also  ihe  relative  position  of  the  luminous  organs,  which  are 
congregated  in  groups,  is  subject  to  unimportanl  variations. 
Two  forms  arc  recognized  by  Giinther: 

(1)  in  the  first  and  more  common  (Fig.  I>)  the  eye  is  comparatively  larger  and  its 
diameter  more  than  the  depth  of  the  triangular  space,  which  is  formed  by  the  margins  of 
the  preoperculum,  of  the  jaws,  and  of  the  orbil :  the  upper  part  of  the  mouth  is  also  con- 
spicuously above  the  level  of  the  lower  margin  of  the  orbit. 

(2)  In  tli  c  second  form  (Fig.  D')  the  diameter  of  the  eye  is  not  longer  than  the  <  1  «'i  >t  li  of 
the  triangular  spare  described,  and  the  upper  pari  of  the  clef!  of  the  month  is  on  a  level 
with  the  lower  margin  of  the  orbit. 

Both  tonus  occur  in  the  Indo-Pacitic  as  well  as  Atlantic,  and  seem  sometimes  to  have 
been  obtained  on  the  same  occasion;  and  as,  moreover,  intermediate  forms  occur  which 
migirl  be  assigned  to  either  of  the  two  forms,  it  is  evident  that  the  differences  mentioned 
are  not  of  specific  value. 

Very  young  specimens,  of  15  millimeters  in  length,  were  found  by  Giinther  already  to 

possess  all  the  characteristics  of  the  adult. 

Specimens  of  this  species  were  taken  by  the  Blake,  from  Station  xxxv,  off  Santa  Cruz, 
at  a  depth  of  508  fathoms;  from  Station  cccxxiu,  in  33°  19'  N.  hit.,  70  1l"  30"  W.  Ion.,  at 
a  depth  of  -T.7  fathoms:  and  from  Station  CCOXVT,  in  32<:  7'  >T.  hit.,  78  .".7'  30"  \Y.  Ion.,  at  a

by  the  schooner  Guy  Cunningham  off  the  Grand  Bank  at  a  depth  of  150  fathoms. 

Dr.  Giinther,  after  studyingthe  specimens  obtained  during  the  voyage  of  the  Challenger, 
reached  the  conclusion  that  its  frequent  capture  at  all  depths  from  surface  downward  is 
only  a  proof  of  its  abundance  in  all  tropical  seas,  and  of  the  slowness  of  its  movements, 
which  prevent  it  from  getting  out  of  the  way  of  the  dredge  or  net.  He  infers  that,  like 
Argyropeleeus,  it  is  a  pelagic  fish,  which  probably  lives  in  shoals,  as  sometimes  more  than 
one  example  were  obtained  in  the  same  haul,  and  that  possibly  it  may  descend  to  or  beyond 
the  100  fathom  line  during  the  daytime.  More  information  is  needed  upon  all  these 
points.

A.  hemigymnus,  is  according  to  Giinther,  common  in  the  Mediterranean  and  neighbor- 
ing parts  of  the  Atlantic,  and  frequently  caught  at  night  in  the  surface  net.  During  the 
cruise  of  the  Porcupine  an  adult  example  was  obtained  between  Shetland  and  Faroe,  at  a 
depth  of  180  fathoms.  Giinther  concludes  that  this  fish  is  of  nocturnal  habits,  living  dur- 
ing the  day  at  a  depth  below  the  surface  which  varies  according  to  circumstances.  The 
French  expedition  obtained  it  in  the  Gulf  of  Marseilles  in  1,060  meters;  in  the  Gulf  of 
Gascony  in  741-1,534  meters;  off  the  Canaries  in  1,200  meters;  off  the  coast  of  Portugal,  in 
950-1,100  meters,  and  off  the  coast  of  Morocco  in  1,123  meters. 

This  form,  though  usually  very  rare  in  the  Mediterranean,  sometimes  is  found  in  such 
abundance  that  it  is  evident  that  in  certain  localities  and  depths  it  must  be  one  of  the 
commonest  of  forms.  Giglioli  obtained  in  September,  1878,  at  Messina,  over  seven  hundred 
in  three  days,  brought  to  the  surface  by  the  swift  current  passing  through  the  Straits. 

Two  specimens  of  this  species  were  obtained  by  the  Blake,  from  Station  cccxv,  in  32° 
18'  40"  N.  lat.,  78°  43'  W.  Ion.,  at  a  depth  of  225  fa-thorns.  One  specimen  (No.  31709,  U.  S. 
N.  M.)  was  takenby  the  Fish  Haul:  from  station  1112,  in  39°  50'  N.  lat.,  70°  35'  W.  Ion.,  at 
a  depth  of  245  fathoms;  and  one  by  the  Albatross  from  station  2117,  in  15°  24'  40"  N.  lat., 
63°  31'  30"  W.  Ion.,  at  a  depth  of  683  fathoms. 

A  species  closely  similar  was  taken  by  the  Investigator  in  the  Indian  Ocean,  station  118, 
in  103  fathoms.  (Alcock,  Ann.  and  Mag.  Nat.  Hist.,  1891,  n,  120.)  It  may  be  called  A. 
AlcocM.

This  species,  like  the  others  just  described,  has  hitherto  been  considered  to  be  a  pelagic, 
surface  form,  and  has  now  and  then  been  found  as  far  north  as  the  coast  of  Norway,  and  was 
taken  by  the  French  expedition  i  >ff  Portugal  in  950  and  1,015  meters.  The  Challenger  dredged 
a  specimen  2J  inches  long,  at  a  depth  of  1,125  fathoms,  at  Station  I,  off  Cape  Finisterre. 

Dr.  Giinther,  discussing  this  occurrence,  remarks:  "The  question  arises  whether  the 
fish  was  really  captured  at  this  great  depth,  or  whether  it  entered  the  dredge  during  its

passage  through  the  surface  strata;  and  I  am  very  much  inclined  to  think  that  the  latter 
took  place  We  have  very  little  positive  information  as  to  the  habits  of  these  fishes,  but 
we  know  that  they  arc  commonly  obtained  near  the  surface  in  mid  ocean;  and  from  their 
structure  ;vc  may  infer  that,  like  all  deep,  compressed  fishes,  they  are  slow  swimmers,  and 
that  they  can  with  ease  maintain  a  free  position  in  the  water,  without  the  necessity  of  a 
support,  remaining  as  it  were  at  a  certain  distance  from  the  surface.  This  may  be  observed 
iu  a  lish  of  our  own  seas  with  a  similar  elevated  body,  viz,  the  John  Dory,  in  which,  how 
ever,  a  rapid  andulatory  movement  of  the  soft  dorsal  tin  is  almost  unceasing.  The  great 
development  of  the  luminous  organs,  combined  with  the  large  eyes,  indicates  the  nocturnal 
habits  of  the  fish,  which  would  induce  it  to  descend  to  a  greater  depth  during  the  day- 
time. Also  the  firm  structure  of  the  bones  disproves  the  bathybiaJ  habits  of  Argyropelecus."

POLYIPNUS,  GUnther. 

Polyipnus,  Gunther.  Challenger  Report,  xxn,  1887, 170,  (type,  P.  spinosus,  from  the  surface  near  the  Philippine 

Islands.) 

Polyipnus  differs  from  Sternoptyx  in  having  the  body  covered  with  very  large  anterior 
scales  and  in  lacking  the  anterior  spinal  dilatation  of  the  anal  fin.  Its  body  is  more  reg- 
ular in  form,  there  being  no  deep  indentation  at  the  base  ot  the  tail;  and  there  are  other 
salient  characteristics,  chief  among  them  the  extraordinary  development  of  the  luminous 
organs  in  size  and  number,  not  less  than  55  phosphorescent  organs  on  each  side. 

The  type  of  this  genus  is  Polyipnus  spinosus  (Fig.  149),  obtained  by  the  Challenger 
between  the  Philippine  Islands  and  Borneo  at  a  depth  of  250  fathoms  (GUnther,  Challenger 
Report  xxn,  170,  pi.  li,  fig.  B.)  and  by  the  Investigator  in  the  Bay  of  Bengal  188-210  fath- 
oms. It  differs  from  Sternoptyx  in  having  the  body  a  more  regular  shape,  there  being  no 
deep  indentation  by  which  the  tail  is  separated  from  the  trunk,  and  in  other  characteristics 
described  by  Gimther.

The  first  individual  obtained  was  caught  in  February.  It  was  a  female  with  eggs, 
which  were  in  two  masses  lying  side  by  side,  5i  inches  long,  notcovered  with  a  sac  Pyloric 
cujca  12,  small.  Air  bladder  5  inches  long  and  with  a  delicate  silvery  coat,  intestine 
straight.  Peritoneum  black  anteriorly,  posteriorly  with  patches  of  black  lines  on  a  pale 
ground.  (Johnson.)  Two  specimens  (No.  34418,  U.  S.  N.  M.),  one  10i  inches  and  the  other 
21  inches  in  length,  were  obtained  by  the  Albatross  at  station  2181,  in  39°  29'  N.  hit.,  71°  40' 
W.  Ion.,  at  a  depth  of  093  fathoms. 

Others  were  obtained  by  the  Blake  at  stations  Lxvn,  128-240  fathoms,  and  lxviii, 
243-458  fathoms,  off  Guadeloupe  and  Santa  Lucia. 

HALOSAURUS  JOHNSONIANUS,  Vaillant.     (Figure  153.) 
Halosaurus  Johnsoniamis,  Vaillant,  Exp.  Sci.  Travailleur  et  Talisruau,  181,  pi,  xv,  fig.  2,  2\  2b,  2C,  2*. 

This  Halosaurus  is  very  similar  to  the  preceding,  but  does  not  appear  to  reach  so  large 
a  size.  The  form  is  more  slender,  the  height  not  exceeding  one  twenty-fifth  of  the  total 
length ;  the  body  is  cylindrical,  but  it  should  be  remarked  that  we  have  not  obtained  a  sin- 
gle example  in  a  state  of  preservation  comparable  to  that  of  certain  individuals  of  the  pre- 
ceding species  (Halosaurus  Oweni). 

The  form  of  the  head,  the  proportions  of  the  muzzle,  those  of  the  eye  and  the  inter- 
orbital  space,  the  arrangement  of  the  gill  cover  offer  nothing  distinctive.  Moreover,  if  we 
may  be  able  to  judge,  this  last  is  not  scaled;  but  on  the  temples  and  the  upper  part  of  the 
head  scales  are  present  without  doubt. 

The  vent  is  very  little  behind  the  anterior  third  of  the  body  and  is  distant  from  the 
end  of  the  snout  only  3  times  the  length  of  the  head. 

The  origin  of  the  dorsal  is  at  a  distance  from  the  end  of  the  snout  equal  to  twice  the 
length  of  the  head.  The  pectorals  do  not  reach  nearly  to  the  insertion  of  the  ventrals, 
which  is  at  a  distance  from  the  end  of  the  snout  less  than  twice  the  length  of  the  head; 
the  ventral  is  wholly  in  advance  of  the  dorsal. 

The  coloration,  although  approaching  that  of  Halosaurus  Oweni,  Johnson,  shows  certain 
differences.  Each  scale  shows  at  its  free  extremity  a  black  spot,  forming  a  reticulation  in 
check  pattern.  The  dark  scales  of  the  lateral  line  form  a  pronounced  band;  finally,  as  in  the 
following  pages,  the  dark  color  of  the  branchial  cavity  is  more  extended  on  the  scapular 
regions,  extends  across  the  gill  covers  and  on  the  whole  head.  These  characters,  together 
with  the  accessory  characters,  are  sufficient  to  distinguish  this  species  from  the  preceding, 
to  which  it  is  nearly  related.

root  of  the  ventral,  and  also  over  the  thirty-first  scale  in  the  specialized  lateral  line.  Two 
scales  between  lateral  line  and  origin  of  the  ventral;  ventral  broad,  the  length  slightly 
longer  than  that  of  longest  dorsal.  Pectoral  fin  moderate,  extending  less  than  half  way 
from  its  owi  base  to  the  root  of  the  ventral,  its  length  equal  to  half  that  of  the  head.  Scales

ALDROVANDIA,  Goode  and  Bean,  n.  g. 

Lyopomi,  with  ventrals  normal;  no  second  dorsal  fin;  vertex  scaleless;  scales  of  lateral

ridges.  Anal  fin  moderate,  high;  its  height  one-third  to  one-fourth  that  of  dorsal.  Type 
Halosaurus  rost7-atus,  Giinther. 

This  genus  is  dedicated  to  Ulysses  Aldrovandus,  of  Bologna,  the  founder  of  the  first 
natural  history  mnseum,  whose  name,  strangely  enough,  has  never  been  honored  by  asso- 
ciation with  a  genus  of  animals  or  plants.

"The  length  of  the  head  much  exceeds  the  height  of  the  body.  The  snout  very  much 
produced,  spatulate,  its  preoral  portion  being  more  than  one  half  of  its  length.  Eye  of 
moderate  size,  its  length  being  one-third  of  the  postocular  portion  of  the  head,  and  consid- 
erably  less  than  the  width  of  the  interorbital  space.  Maxillary  scarcely  reaching  the  front 
margin  of  the  eye.  The  length  of  the  head  is  a  little  more  than  its  distance  from  the  root 
of  the  ventral,  which  is  nearly  entirely  situated  before  the  dorsal.  Nearly  all  the  scales  are 
lost,  but  some  of  the  lateral  line  remain;  they  are  much  larger  than  the  other  scales;  and 
on  the  tail,  where  the  lateral  line  approaches  the  lower  profile,  these  larger  scales  fill  up  all 
the  space  between  the  lateral  line  and  the  anal  fin. 

"  Distance  of  the  snout  from  the  mouth,  SJ,  lines;  distance  of  the  snout  from  the  eye,  1

of  the  snout  from  the  root  of  the  ventral,  1  inches  10  lines;  distance  of  the  snout  from  the 
origin  of  the  dorsal,  5  inches  8  lines;  distance  of  the  snout  from  the  vent,  6  inches  11  lines; 
total  length,  20  inches. 

"  Bones  of  the  head  very  thin;  operculum  smooth,  covered  with  a  very  fine  membrane. 
The  lower  part  of  the  side  of  the  head  is  occupied  from  the  snout  to  the  gill  opening  by  two 
exceedingly  wide  muciferous  channels,  of  which  one  takes  its  origin  on  the  preorbital,  the 
other  on  the  mandible,  and  which  open  behind  at  the  gill  opening  by  a  common  and  very 
wide  aperture.  Branchial  apparatus  as  in  the  other  species.  The  dentition  is  very  similar 
to  that  of  Halosaurus  macrochir,  but  the  palatine  patches  are  crescent-shaped  and  rather 
widely  separated  from  the  pterygoid  band. 

"The  scales  of  the  lateral  line  are  about  three  times  the  size  of  the  others,  and  about 
twenty-four  in  number  between  the  gill  opening  and  the  vent.  Each  bears  a  luminous 
organ,  vertically  elongated  and  rhombic,  but  not  extending  to  the  upper  and  lower  margins 
of  the  scales.  Light  color,  the  lower  part  of  the  head  and  the  gill  cover  black;  abdominal 
region  blackish."

Snout  moderately  produced,  the  preoraJ  portion  forming  only  one-third  of  its  length. 
Bye  rather  small,  one-fourth  of  the  postocular  portion  of  the  head,  and  one-half  of  the 
width  of  the  interorbital  space.  Maxillary  reaching  to  the  front  margin  of  the  eye.  The 
length  of  the  head  is  more  than  its  distance  from  the  root  of  the  ventral,  the  origin  of 
which  is  immediately  in  front  of  that  of  the  dorsal.  Pectoral  tin  with  narrow  base,  very 
long,  extending  nearly  to  the  root  of  the  ventral.  Scales  of  the  lateral  line  larger  than  the 
others,  more  or  less  hidden  in  a  pouch  of  black  skin,  with  a  phosphorescent  organ  at  the 
base  of  the  free  portion.  These  large  scales  are  continued  for  some  length  on  the  tail  and 
cover  the  base  of  the  anal  fin,  which,  like  the  dorsal,  is  covered  in  its  basal  half  with  small 
scales.     Uniform  black. 

The  entire  head  is  naked ;  only  the  upper  portions  of  the  gill  cover  and  of  the  cheek  are 
covered  with  scales  similar  to  those  of  the  body. 

The  baud  of  intermaxillary  teeth  is  broader  than  the  maxillary  band.  Palatine  teeth 
in  two  separate  patches,  each  being  of  an  oval  shape,  with  the  pointed  end  directed  for- 
wards; pterygoid  teeth  in  a  very  narrow  band,  which  extends  far  backwards  in  the  cavity 
of  the  mouth;  basibranehials  with  a  long  and  broad  band. 

Pour  well  developed  "ills.  Outer  branchial  arch  with  14  widely-set  gill  rakers,  of 
which  the  middle  ones  are  slender  and  as  long  as  the  eye,  the  others  becoming  shorter

head  is  longer  than  the  distance  between  it  and  the  root  of  the  ventral.  The  supramaxil- 
lary  reaches  the  vertical  of  the  front  margin  of  the  eye.  The  dorsal  is  entirely  behind  the 
ventrals;  the  anal  commences  as  far  behind  the  root  of  the  ventrals  as  the  latter  is  behind 
the  preoperculum;  the  pectorals  nearly  reach  backward  to  the  ventrals.  The  squamation 
is  similar  to  that  of  the  A.  macrochira.

Halosaurus  phalacrus,  Vaillant,  Exp.  Sci.  Travailleur  et  Talisman,  185,  pL  xv,  fig.  3;  pi.  xvi,  figs.  1 — lc. 

In  appearance  and  in  general  proportions  this  species  approaches  the  Halosaurus 
macrochir  of  Giinther,  being,  however,  a  little  more  slender,  so  that  the  height  is  less  than 
one-twentieth  of  the  total  length;  the  body  is  a  little  more  compressed. 

The  head  is  one-ninth  of  the  total  length;  it  is  equally  depressed  below  and  notably 
more  elongate,  so  that  the  muzzle  is  spatuliform.  The  snout  is  three  sevenths  of  the  length 
of  the  head,  the  preoral  portion  occupying  its  anterior  third.  The  horizontal  diameter  of 
the  eye  equals  the  width  of  the  interorbital  space  and  is  one-seventh  of  the  length  of  the 
head.    Scales  on  the  operculum  and  the  temporal  region;  upper  part  of  the  head  naked. 

The  origin  of  the  dorsal  is  at  a  distance  from  the  tip  of  the  snout  equal  to  the  length  of 
the  head.  Pectorals  not  reaching  to  the  insertion  of  the  ventrals,  which  are  at  a  distance 
from  the  gill  opening  notably  less  than  the  length  of  the  head;  the  ventrals  are  short  and 
placed  in  advance  of  the  dorsal.  This  tish  in  the  fresh  state  shows  a  flesh  pink  tint;  the 
anal  dusky,  approaching  to  brown;  the  head  bluish  black.  Total  length  (millimeters),  430; 
height,  20.04;  thickness,  13.03;  length  of  the  head,  53.12;  length  of  the  snout,  21.45;  diame-

The  examples  recorded  by  Vaillant  are  from  oft'  the  coast  of  Morocco,  Soudan,  and  the 
Azores,  in  depths  ranging  from  1,103  to  2,220  meters. 

ALDROVANDIA  GRACILIS,  Goode  and  Bean,  n.  s.     (Figure  157.) 

This  is  a  very  slender  species  and  resembles  H.  rostratus,  from  which  it  differs  in  having 
a  larger  eye,  a  smaller  number  of  modified  scales  in  the  lateral  line,  and  in  having  the  vent 
placed  more  posteriorly.  The  description  is  made  from  the  Albatross  specimen  taken  at 
station  2380.  The  length  of  this  individual  is  490  millimeters.  The  greatest  height  of  the 
body  (24  millimeters)  is  contained  204  times  in  the  total  length,  and  about  2i  times  in  the 
length  of  the  head.  The  greatest  width  of  the  body  (17  millimeters)  is  two-thirds  of  its 
greatest  height.  The  length  of  the  head  (GO  millimeters)  is  contained  s1,  times  in  the  total. 
The  greatest  width  of  the  head  (17  millimeters)  equals  the  length  of  the  maxilla.  1  >istance 
from  the  end  of  the  mouth  to  the  tip  of  the  snout  (11  millimeters)  equals  nearly  one-fifth 
the  length  of  the  head.  The  length  of  the  snout  (27  millimeters)  is  a  little  greater  than 
the  length  of  the  mandible.  The  width  of  the  interorbital  space  (7  millimeters)  is  about 
one-fourth  the  length  of  the  snout  and  three-fourths  the  length  of  the  eye.  The  maxilla 
extends  to  slightly  beyond  the  anterior  margin  of  the  eye;  the  mandible  a  little  behind  the 
end  of  the  eye.  At  present  the  head  contains  a  few  scales  in  several  series  behind  the  eye. 
The  diameter  of  the  eye  (9  millimeters)  is  equal  to  one-third  the  length  of  the  snout,  and 
about  two-fifths  of  the  length  of  the  postorbital  part  of  the  head.  The  mouth  is  rather 
large.  Teeth  on  the  intermaxillaries  and  mandible  in  somewhat  broader  bands  than  those 
on  the  maxilla.  Vomerine  patches  broad,  well  separated  in  front.  Tip  of  tongue  free. 
Integumentary  flap  not  extending  much  beyond  the  margin  of  the  subopercle.  Branchi-

length  of  the  head.  The  length  of  the  base  (17  millimeters)  is  two-thirds  of  the  height  of 
the  body.  The  longest  ray  is  two-fifths  as  long  as  the  head  and  nearly  equal  to  the  height 
of  the  body,  about  34  rows  of  scales  in  front  of  the  dorsal.  The  ventral  is  entirely  in 
advance  of  the  dorsal;  its  distance  from  the  end  of  the  head  (49  millimeters)  equal  to  the 
distance  from  the  tip  of  the  mandible  to  the  end  of  the  head.  The  length  of  the  ventral 
1 18  millimeters)  is  about  equal  to  that  of  the  dorsal  base  and  twice  the  length  of  the  eye. 
The  origin  of  the  ventral  is  about  under  the  twenty-eighth  row  of  scales.  The  distance  of 
the  vent  from  the  origin  of  the  ventral  (66  millimeters)  is  greater  than  the  length  of  the 
head;  it  is  close  to  the  anal  origin.  The  distance  from  the  dorsal  origin  to  that  of  the  anal 
(53  millimeters)  equals  3  times  the  length  of  the  dorsal  base.  Nine  or  10  enlarged  scales  in 
the  lateral  line  in  front  of  the  ventral  origin  and  about  the  same  number  between  the 
ventral  and  the  vent. 

The  dorsal  is  scaly,  less  than  one-half  of  its  height;  about  12  rows  of  scales  between 
the  dorsal  origin  and  the  lateral  line,  and  only  about  two  rows  below  the  lateral  line. 

Scales  silvery,  the  light  orange-brown  body  color  showing  through  them.  Branchios- 
tegal  membrane  bluish;  inner  surface  of  gill  covers  nearly  black;  inside  of  month  bluish. 

Three  specimens  are  known,  one  obtained  by  the  Blake,  at  Station  lxx,  off  Guadaloupe, 
769  fathoms;  one  at  station  2380  by  the  Albatross,  and  another  at  station  2381  by  the  same 
vessel.  Station  2380  is  in  N.  lat.  28°  02'  30",  W.  Ion.  87°  43'  45",  from  1,430  fathoms.  Sta- 
tion 2381  is  in  K.  lat.  28°  05'  00",  W.  Ion.  87°  56'  15",  1,330  fathoms. 

It  is  not  impossible  that  this  species  may  be  identical  with  17.  Jolinsoniamts  of  Vaillant, 
but  the  types  of  the  French  naturalist  were  so  much  mutilated  that  his  description  is  not 
sufficient  to  establish  the  relationship. 

ALDROVANDIA  PALLIDA,  Goode  and  Bean,  n.  s.    (Figure  158.) 

Greatest  height  of  the  body  at  origin  of  the  dorsal  and  is  contained  15  times  in  the 
total  length,  and  is  about  one-half  the  greatest  length  of  the  head,  which  is,  including 
the  subopercular  flap,  78  millimeters,  and  contained  about  1%  times  in  the  total  length. 
The  greatest  width  of  the  body  (21  millimeters)  is  a  little  more  than  one  half  its  greatest 
height.  The  greatest  depth  of  the  head  (24  millimeters)  is  a  little  less*than  one-third  of  its 
length  and  nearly  equal  to  its  greatest  width.  The  head  is  naked,  with  the  exception  of  a 
patch  of  scales  beginning  behind  the  eye;  its  greatest  width  (10  millimeters)  nearly  equal 
tooue-half  the  width  of  the  body.  The  eye  is  midway  between  the  tip  of  the  snout  and  the 
end  of  the  head.  Its  long  diameter  (11  millimeters)  equal  to  one  third  the  length  of  the 
snout  (33  millimeters),  also  equal  to  the  width  of  the  interorbital  space.  The  nostrils  are 
close  to  the  front  of  the  eye,  the  anterior  in  a  short  tube,  which  ends  in  a  little  pointed  flap; 
the  posterior  larger,  nearly  elliptical  in  shape.  The  distance  from  the  front  margin  of  the 
mouth  to  the  tip  of  the  snout  (16  millimeters)  equals  nearly  one-half  the  length  of  the  snout. 
The  maxilla  extends  to  below  the  front  margin  of  the  eye.  Teeth  in  broad,  villiform  bands 
on  the  intermaxilla,  mandible,  and  vomer;  in  narrower  bands  on  the  maxilla  and  palatines. 
End  of  the  tongue  barely  free.  The  integumentary  flap  projecting  beyond  the  margin  of 
the  suboperculum.  The  dorsal  originates  about  over  the  end  of  the  base  of  the  ventral. 
Its  distance  from  the  tip  of  the  snout  a  little  more  than  twice  the  length  of  the  head.  The 
length  of  its  base,  (23  millimeters)  nearly  equal  to  thegreatesi  depth  ofthe  head.  The  basal 
half  of  the  fin  is  profusely  covered  with  scales;  it  consists  of  two  simple  and  nine  divided 
rays.  The  longest  dorsal  ray  (30  millimeters)  equals  three  fourths  the  greatest  height  of 
the  body.  The  last  ray  (12  millimeters)  is  two-fifths  as  long  as  the  third.  The  ventralis 
distant  from  the  snout  a  space  about  equal  to  twice  the  length  of  the  head.  It  consists  of 
two  simple  and  seven  divided  rays;  the  longest  ray  (23  millimeters)  equal  to  base  of  dorsal. 
The  pectoral  is  placed  above  the  middle  of  the,  body  not  far  from  the  head.  Its  length  (35 
millimeters)  equal  tooue-half  the  distance  of  its  base  from  the  origin  ofthe  ventral;  it  reaches 
to  about  the  seventeenth  row  of  scales.  The  vent  is  under  the  sixty-third  scale  ofthe  lateral 
line;  there  are  about  12  rows  of  scales  between  the  origin  of  the  dorsal  and  the  lateral  line

and  about  2£  rows  between  the  lateral  line  and  the  origin  of  the  ventral.  The  lateral  line 
is  composed  of  enlarged  and  modified  scales,  and  becomes  obliterated  about  the  middle  of 
the  length  of  the  tail.  There  are  15  or  16  of  these  enlarged  scales  between  the  head  and 
the  origin  of  the  ventral;  about  27  between  the  vent  and  the  head.  The  distance  from  the 
origin  of  the  ventral  to  the  anus  (73  millimeters)  is  nearly  equal  to  the  length  of  the  head. 
The  anal  fin  begins  not  far  behind  the  vent  and  contains  about  100  rays.  The  caudal,  which 
is  long  and  slender,  contains  about  1  rays;  the  pectoral  13.  The  membrane  covering  the 
anal  rays  is  scaled  throughout  almost  its  entire  length.  Gill  rakers  rather  short  and  few; 
three  above  the  angle,  twelve  below. 

The  color  of  the  scales  is  a  light  silveryr  gray,  through  which  the  body  color  appears  as 
alight  orange-brown.  Branchiostegal  membrane  and  opercular  bones  bluish.  Inside  of 
gill  covers  very  dark  blue. 

A  single  individual,  the  type  of  the  species,  600  millimeters  in  length,  was  taken  by  the 
Blake  at  Station  clxxiii,  in  24°  30'  1ST.  lat.,  84°  05'  W.  Ion.,  at  a  depth  of  955  fathoms.

A  species  distinguished  from  V.  Upturns  by  a  more  compressed,  higher  body  and 
tail,  the  thickness  one-fiftieth,  the  height  one-twentieth  of  total;  by  the  presence  of  two 
strong  teeth,  one  behind  the  other,  on  the  anterior  portions  of  the  vomer,  and  by  a  space 
separating  the  gill  openings  which  is  considerably  greater  than  the  diameter  of  these 
openings. 

U.  vicinus,  the  sole  representative  of  this  genus  in  the  Atlantic,  was  obtained  by  the 
French  explorers  from  the  Banc  d'Axguin,  1,495  meters;  off  Soudan,  932  meters,  and  at  the 
Cape  Verde  Islands,  in  633  meters  depth ;  three  from  the  first  locality,  one  from  each  of  the 
others.

140  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

Head  blunt,  rounded,  bulldog-like  iu  aspect;  angle  of  mouth  midway  between  the  tip 
of  suout  and  anterior  edge  of  eye.  Body  stout,  its  depth  at  origin  of  dorsal  about  equal  to 
length  of  bead.  Dorsal  origin  a  head's  length  behind  gill  openings;  diameter  of  eye  half 
the  length  of  the  snout  or  a  little  more;  length  of  pectoral  two-fifths  that  of  head;  length 
of  body  ten  or  eleven  times  that  of  the  head;  tail  a  head's  length  longer  than  head  and 
trunk.     Color  brown,  uniform. 

This  very  remarkable  form  was  first  known  from  a  few  specimens  brought  to  Glouces- 
ter in  1879  by  the  fishing  vessels.  It  burrows  in  the  muscles  of  living  halibut  and  other 
large  fishes,  after  the  manner  of  Myxine,  and  excavates  large  cavities  in  the  thickest  parts 
of  their  bodies.  These  first  examples  were  from  depths  of  200  to  300  fathoms.  Subse- 
quently the  Albatross  obtained  it  from  various  bottom  localities  at  depths  of  from  200  to 
904  fathoms. 

This  fish  has  occasionally  been  found  embedded  in  the  flesh  of  larger  fishes,  but  has 
also  been  obtained  in  the  trawl  net  by  the  Albatross  at  the  following  stations: 

No.  35002,  U.  S.  N.  M.,  was  from  station  22J  (8,  in  39°  06'  N.  lat,,  72°  10'  W.  Ion.,  in  904  fathoms ;

09'  W.,  at  a  depth  of  200  fathoms. 

In  1889  numerous  examples  of  an  anguilliform  fish  were  taken  in  nets  at  the  Azores 
Islands  at  depths  varying  from  844  to  2,000  meters  by  the  yacht  Hirondelle,  under  the  aus- 
pices of  the  Prince  of  Monaco.  These  were  subsequently  determined  to  belong  to  a  peculiar 
form  called  by  Dr.  Bobert  Collett  Conchognathus  Grimaldii.  A  comparison  of  the  description 
given  indicates  plainly  that  the  supposed  new  generic  type  is  identical  with  Simenchelys.  It 
has  the  same  scaly  skin,  short,  truncated  head,  small  mouth,  acrodont  teeth,  inferior  branchial 
slits,  and  large  "  conchiform"  lower  jaw,  reference  to  which  is  conveyed  in  the  generic  name. 

The  question  naturally  arises,  says  Gill,  whether  the  Simenchelys  parasiticus  and 
Conchognathus  Grimaldii  are  distinct.  So  far  as  can  be  judged  from  tin-  description  of  Dr. 
Collett  this  question  must  be  answered  in  the  negative.  The  measurements  of  two  speci- 
mens of  nearly  the  same  size  correspond  closely  enough  for  specific  purposes,  except  as  to 
height.  That  measurement  for  the  Conchognathus  Grimaldii  has  evidently  been  obtained 
from  a  specimen  with  a  very  full  belly,*  and  not  at  the  pectoral  or  anal  region.  The  meas- 
urements from  an  American  specimen  are  subjoined  for  comparison  with  measurement  of  an 
Azorean  one  given  by  Dr.  Collett : 

*Le  corps  est  comprint;  le  niuseau  est  tronqu€;  le  ventre  un  peu  pendant,  tics  dilatable. — Collett,  op. 
cit.,  p.  124.

longer  (ban  snout.  CTniform brown,  rather  darker  below;  the  vertical  fins  darker  behind, 
light-edged  anteriorly;  inside  of  mouth  blue-black;  gill  openings  dark. 

This  remarkable  eel  was  first  made  known  by  the  Madeiran  ichthyologists,  Lowe  and 
Johnson,  by  whom  it  was  found  at  74(1  fathoms  and  in  intermediate  depths.  The  Challenger 
obtained  it  near  the  coast  of  Brazil,  in  1,200  fathoms;  off  Japan,  in  345  to  565  fathoms;  and 
about  the  Philippines,  in  375  to  500  fathoms.  Its  presence  iu  the  western  Atlantic  was  first 
detected  by  the  Cape  Ann  fishermen,  who  in  1S79  began  bringing  them  in  from  the  offshore 
banks,  where  they  had  been  taken  on  trawl  lines  at  200  to  300  fathoms.  In  1879  the  Fish 
Hawk  took  it  often  in  250  to  365  fathoms,  and  subsequently  the  Albatross  and  the  Blake 
brought  it  in  from  numerous  stations  at  depths  of  300  to  1,000  fathoms.  The  Travailleur 
and  Talisman  took  it  in  numerous  localities;  off  Morocco,  912-2,210  meters;  off  the  Canaries, 
865-2,083  meters;  off  Soudan,  882-1,435  meters;  on  the  Banc  dArguin,  1,113-1,550;  off 
the  Cape  Verdes,  405-3,200;  off  the  Azores,  1,257-2,235  meters. 

Specimens  of  this  species  were  obtained  by  the  Blake  from  the  following  localities:

A*,  brevidorsalis,  from  the  Pacific  Ocean,  north  of  New  Guinea,  1,070  fathoms,  and  oft 
Japan,  345  fathoms  (Giinther,  Challenger  Report,  xxu,  255,  pi.  lxiii,  fig.  c),  resembles  S. 
pinnattis  in  general  structure;  but  its  dorsal  fin  begins  far  behind  the  vent,  rather  than 
above  it,  as  in  the  other  species. 

The  species  described  by  Dr.  Giinther  as  *S".  affinis  is  now  considered  by  him  to  be  iden- 
tical with  the  Atlantic  form.  It  was  taken  by  the  Challenger,  station  232,  off  Inosima,

Synaphobranchids  with  origin  of  dorsal  almost  as  far  forward  as  the  base  of  the  pec 
toral  and  far  in  advance  of  the  anal.  Vent  nearly  in  the  middle  of  the  length  of  the  body. 
Vomerine  teeth  in  two  patches,  that  in  front  being  the  larger,    ((rill.)

Histiobranchus  infernalis,  Gill,  loc.  tit. 

Synaphobranchus  infernalis,  GCnther,  Challenger  Report,  xxu,  254. 

Body  moderately  elongated  and  compressed;  its  height  at  the  anus  equals  .56  of  the 
length  and  the  greatest  width  above  the  stomach  being  less  than  two  thirds  of  the 
height.  The  head  forms  about  one-ninth  of  the  total  length,  and  its  width  is  a  little  less 
than  one-half  its  length;  the  snout  is  moderate,  the  length  being  less  than  the  greatest 
width  of  the  head.  The  eye  is  also  moderate,  its  diameter  being  much  less  than  one  hall' 
the  length  of  the  snout. 

The  upper  jaw  is  nearly  one-tenth  of  the  total  length  and  the  lower  jaw  a  little  mure. 

The  dorsal  commences  not  far  behind  the  vertical  from  the  root  of  the  pectoral,  while 
the  anal  arises  little  nearer  the  snout  than  the  end  of  the  tail;  both  are  moderately  devel- 
oped. 

The  pectorals  are  considerably  shorter  than  the  snout. 

The  color  in  life  is  said  to  be  an  almost  uniform  dark  plumbeous,  but  in  alcohol  the 
trunk  is  dark  yellowish  brown,  becoming  almost  black  on  the  abdominal  region  and  around 
the  pectoral  as  well  as  on  the  iutermandibular  integuments  and  around  the  pectorals,  while 
the  dorsal  and  anal  are  whitish  except  towards  the  posterior  fourth  of  the  length,  where 
they  are  very  dark  or  blackish. 

A  specimen,  No.  3327!),  was  taken  by  the  Albatross  at  station  2037,  lat.  38°  30'  30"  K, 
Ion.  69°  08'  25",  W.,  in  1,731  fathoms. 

Another  species  of  the  same  genus,  characterized  mainly  by  stouter  body  and  lower 
vertical  tins,  is  Histiobranchws  bathybius,  Giinther  (Synaphobranchus  bafhybius,  Giinther, 
Ann.  and  Mag.  Nat.  Hist.,  xx,  1877,  445,  Challenger  Report,  xxu,  254,  pi.  lxii,  tig.  B),  a 
stouter,  chunkier  form,  with  shorter  snout  and  tail,  and  smaller  fins,  obtained  in  the 
Pacific  and  Indian  oceans,  at  depths  from  1,375  to  2,050  fathoms.

Anguilloid  apodals,  with  thick  skeleton,  thin  scaleless  skin,  and  tail  surrounded  by 
vertical  fins;  pectoral  well  developed;  jaws  of  moderate  length;  vomer  well  armed;  pos- 
terior nostril  not  lateral;  tongue  narrow,  its  margins  adnate;  gill  openings  rather  wide. 
"IJranchiostegal  membrane  connecting  the  opposite  sides  below,  the  epipharyngeal 
reduced  to  one  pair,  and  the  nypopharyngeals  linguiform  and  encroaching  on  the  fourth 
branchial  arch." 

"The  characters  which  appear  to  distinguish  the  MurcBnesoces  best  from  the  Anguillids 
and  Con  grids  or  Leptocephalids  are  the  low  position  on  the  hyomandibular  of  the  condyle 
for  the  operculum,  the  slender  branchial  arches  and  the  development  and  position  of  the 
hypopharyngeals  and  epipharyngeals,  the  union  of  the  opposite  branchiostegals  by  the 
inferior  branchiostegal  membrane,  and  the  want  of  freedom  of  the  tongue.  Whether  the 
other  genera  that  have  been  closely  associated  with  Murame80x(ffoplunnis,Oxyconger,N'eo- 
conger,  Nettastoma,  and  Saurencheh/s)  arc  related  to  the  family  can  only  be  determined  by  an

only  ones  known  to  be  certainly  possessed  of  the  characters  provisionally  assigned  to  the 
family."     (Gill.) 

This  family  may  provisionally  receive,  in  addition  to  its  typical  form,  a  number  of 
genera,  chiefly  American.  They  occur  chiefly  in  warm  regions.  Only  three  genera  are  as 
yet  known  from  the  deeper  waters,  Xenomystax,  Hoplunnis,  and  Sauromurcenesox.

A  pair  of  larger  canines  near  the  end  of  the  lower  jaw  in  the  example  figured.  A  row  of 
six  to  eight  strong,  large  canines  on  the  vomer. 

A  single  individual  (No.  44240  U.  S.  Nat.  Mus.)  was  obtained  by  the  Albatross  at  sta- 
tion 2402,  111  fathoms,  lat.  28°  36',  long.  86°  50'. 

SAUROMURCENESOX,  Alcock. 

Sauromurmnesox,  Alcock,  Ann.  and  Mag.  Nat.  Hist.,  Nov.  and  Dec,  1889,  457. 

Form  of  the  body  widely  departing  from  the  typical,  the  trunk  being  high  and  well 
marked  off  from  the  head  and  tail,  which  is  a  long,  tapering  appendage.  Tissues  well  devel- 
oped. Gills  four,  opening  into  the  pharynx  by  wide  slits;  gill  openings  separate.  Heart 
situated  immediately  behind  the  gills.  Nostrils  lateral.  Eye  large.  Tongue  free.  Verti- 
cal fins  ill  developed,  confluent ;  the  dorsal  begins  in  front  of  the  level  of  the  gill  opening. 
Pectoral  fins  well  developed.  No  scales.  Snout  long,  pointed.  Cleft  of  mouth  extending 
far  behind  the  eye;  the  upper  jaw  overlapping  the  lower.  One  complete  row  of  teeth  in 
each  jaw  and  a  second  incomplete  row  in  the  maxilla;  premaxillary  teeth  and  those  at  the 
mandibularly  symphysis  fang- like;  a  single  row  of  large  fangs  in  the  vomer. 

This  genus  is  represented  by  one  species,  S.  vorax,  Alcock,  from  Bay  of  Bengal,  taken 
at  the  depth  of  193  fathoms. 

Family  OPHICHTHYID^E.

Ophichthyoid,  apodal  fishes,  with  gill  openings  rather  wide,  lateral;  scaleless  body,  and 
tip  of  tail  sometimes  free  from  vertical  fins  (sometimes  with  filamentous  caudal  fin).    Pec-

torals  moderate,  weak,  or  absent.    Posterior  nostrils  in  lip  or  near  it;  anterior  nostrils 
sometimes  tabular. 

This  family  includes  a  large  number  of  genera,  of  which  seventeen  are  recognized  by 
Jordan  and  Davis  in  their  paper  on  the  Apodal  Pishes  of  America  and  Europe,  (iill  groups 
them  in  three  subfamilies,  as  shown  in  the  key  already  presented.  * 

These  apod  als  are  found  chiefly  in  warm  seas.    Only  one  genus  of  the  typical  Ophisu 
roids,  Pisoodonophis,  is  found  at  any  distance  below  the  surface.

(1891),  619. 
Pisodontophii,  GUNTHER,  Cut.  Fish.  Brit.  Mus.,  vm,  1870,  55. 

Ophichthyoid  apodals,  with  tip  of  tail  free.  Dorsal  and  anal  fins  well  developed,  the 
former  low,  beginning  far  back.  Teeth  blunt,  granular;  vomer  with  teeth.  Pectoral  fins 
present,  small. 

Of  this  genus,  closely  allied  to  Myrichthys,  a  single  species  has  been  found  at  consid- 
erable depths  in  the  western  Atlantic.  Four  species  from  Indian  seas  are  mentioned  in 
Giinther's  "Catalogue,"  and  he  refers  to  a  half-grown  individual  obtained  from  Grenada, 
in  the  West  Indies,  which  seemed  to  him  identical  with  P.  boro,  the  type  of  the  genus. 
/'.  cruentifer,  described  by  us  below,  is  perhaps  most  closely  allied  to  P.  cancrivorm  (Rich- 
ardson), known  from  the  East  Indian  Archipelago  and  Australia. 

PISOODONOPHIS  CRUENTIFER,  Goode  and  Bean,  n.  s.     (Figure  166.) 

Length  of  the  head  equal  to  one-fourth  of  the  distance  from  the  gill  opening  to  the 
vent,  and  the  length  of  the  body  about  two-thirds  that  of  the  tail.  The  cleft  of  the  mouth 
is  rather  wide,  measuring  one-third  of  the  length  of  the  head,  counting  from  the  end  of  the 
upper  jaw.  The  snout  is  conical,  depressed.  The  head  is  snake-like  in  appearance,  with 
powerful  muscular  enlargements  of  the  cheeks  and  a  constriction  behind  the  head  some- 
what like  that  of  Derichthys.  Eye  moderate,  its  length  half  that  of  the  snout,  and  one- 
tenth  that  of  the  head.  Teeth  granular,  in  conspicuous  bands,  a  small  oblong  patch  on  the 
premaxillaries  and  a  long  band  upon  the  vomer.  The  length  of  the  pectoral  fin  is  about 
two-sevenths  that  of  the  head.  It  is  broad,  spatulate.  The  dorsal  begins  far  behind  the 
tip  of  the  pectoral,  its  distance  from  the  tip  of  the  snout  being  one-seventh  of  the  total 
length,  or  from  gill  opening  to  dorsal  origin  two-thirds  length  of  head.  Dorsal  and  anal 
fins  of  moderate  height. 

Color  uniform  brownish  yellow. 

This  species  has  been  found  in  the  following  localities:  Types,  two  specimens,  No.  28938, 
station  1035  of  the  U.  S.  Fish  Commission  steamer  Fish  Hawk,  were  taken  in  N.  hit.  39° 
57',  W.  Ion.  G9°  28',  in  120  fathoms.  Another  specimen  was  taken  by  the  same  steamer  in 
about  the  same  locality,  No.  30233,  and  three  others,  No.  31711,  in  N.  lat.  39°  56',  W.  Ion. 
70°  35',  in  a  depth  of  245  fathoms.  The  types  of  the  description  are  lOg  and  14^  inches 
long. 

The  peculiar  and  savage  physiognomy  of  this  fish  suggests  at  once  the  idea  that  it  is  a 
parasitic  boring  form,  and  in  confirmation  of  this  we  have  specimens  taken  by  the  fishermen 
on  Jeffrey's  Bank  and  also  another  from  New  Bedford,  taken  by  Mr.  J.  H.  Thompson  from 
the  body  of  a  fish.  We  have  occasionally  taken  the  dried  and  shriveled  remains  of  a  fish 
apparently  closely  related  to  this  from  salted  halibut  and  codfish.

Family  NETTASTOMID^E. 
Nettaetomidw,  Jordan  and  Davis,  Rep.  U.  S.  F.  C,  1888  (1891),  649. 

This  family,  as  understood  by  us,  contains  a  few  species  of  deep-sea  eels  closely  allied 
to  the  Murcenesocidce  in  technical  characters,  but  more  resembling  the  Nemichthyidos  in 
appearance,  form  of  the  head,  and  in  dentition.  The  family,  which  is  a  provisional  one,  may 
be  thus  defined. 

Enchelycephalous  eels  without  pectoral  fins,  with  the  tongue  not  free,  the  posterior 
nostrils  remote  from  the  Up,  the  gill  openings  small,  separate,  and  subinferior,  the  vent 
remote  from  the  head,  the  tail  ending  in  a  slender  tip  <>r  filament,  the  dorsal  and  anal  tins 
moderately  developed,  aud  the  jaws  produced,  slender,  and  straight,  the  upper  the  longer, 
and  both,  as  also  the  vomer,  armed  with  hands  of  sharp,  close-set,  recurved,  subequal  teeth. 

Three  genera  are  known,  deep-sea  fishes  with  fragile  bodies  and  the  thin  skin  charged 
with  black  pigment.     (Jordan  and  Darin.)

Hyoprorus  messitii  nets,  Km  i  [KER,  lu<:  <it.  —  X  uixant,  op.  cil.,  95. 

A  Nettastoma,  with  stunt  upper  jaw.  slighth  projecting  beyond  the  lower  and  without 
prominent  cutaneous  flap;  with  mouth  cleft  not  extending  behind  the  vertical  from  tin-  orbit. 
Teeth  strong.  Tail  three  tilths  the  length  of  the  body.  Diameter  of  the  eye  three-twen- 
tieths the  length  of  the  head.    Pins  margined,  with  black  posteriorly. 

This  form  is  found  in  the  western  Mediterranean,  where  it  has  nol  yei  been  traced  to 
any  considerable  depth.  It  doubtless  is  more  common  in  the  deep  than  in  the  shallow 
waters,  for  its  bathybial  distribution  has  been  demonstrated  in  adjoining  Atlantic  waters. 

Nettastoma  brevirostris,  Facciol$  (Naturalista  Sicihano,  vi,  L887,  ICG,  pl.m,  flg.  3)  is 
apparently  a  closely  allied  form. 

Yaillant  believes  that  he  has  recognized,  in  two  small  individuals  of  (».">  and  142  milli- 
meters, respectively,  the  young  of  Nettastoma,  and  probably  of  this  species,  and  dissents 
from  the  views  of  those  ichthyologists  who  regard  the  Leptocephalus  form — Hyvprorus  mes- 
sinensis — as  the  young,  or  transformed,  Nettastoma.

Closely  allied  to  Nettastoma,  but  with  snout  prolonged  in  a  slender  fleshy  proboscis,  with 
the  anterior  nostrils  at  its  base.    The  type  is  N.  prat  rum,  Goode  and  Bean.

Fenefica procera,  Jordan  and  Davis,  toe.  <it. 

A  Nettastoma  with  body  very  elongate,  compressed,  tapering  to  a  very  slender  atten- 
uate point;  its  greatest  height  contained  nearly  4  times  in  the  distance  from  the  gill  open- 
ing to  the  tip  of  the  lower  jaw,  and  equals  half  the  length  of  the  snout.  Head  slender, 
conical;  jaws  somewhat  depressed;  the  upper  jaw  heavier  and  thicker,  and  projecting 
beyond  the  lower  a  distance  equal  to  the  diameter  of  the  eye.  Length  of  snout  equals  the 
distance  from  the  posterior  margin  of  the  orbit  to  the  gill  opening;  the  cleft  of  the  mouth 
extends  behind  the  eye  to  a  distance  equal  to  the  diameter  of  the  orbit.  On  each  side  of  the 
upper  jaw,  and  in  advance  of  the  eye,  are  twelve  pores;  behind  each  eye  are  three  pores, 
while  on  the  median  line,  on  the  top  of  the  upper  .jaw,  are  several  pores  posteriorly  arranged 
in  pairs,  of  which  there  are  four,  the  ultimate  pair  being  between  the  posterior  nostrils. 
There  is  also  a  pair  of  pores  upon  the  nape,  connecting  the  postorbital  rows,  and  seventeen 
on  each  side  of  the  mandible.  The  mandibulary  series  is  continued  by  another  series 
extending  over  the  cheeks  and  nape.  The  snout  is  provided  with  a  slender,  filamentous  tip, 
whose  length  is  equal  to  twice  the  diameter  of  the  eye.  The  tongue  is  apparently  absent  in 
the  specimens  examined  by  us.  The  teeth  are  arranged  as  in  N.  melanurum,  but  exceed 
ingly  small,  and  much  less  conspicuous  than  in  the  figures  of  Eaup  and  Risso. 

Dorsal  tin  commences  above  the  gill  opening. 

The  anal  fin  is  inserted  under  the  seventy-third  dorsal  ray  at  a  distance  from  the  snout 
equal  fco3§  times  the  length  of  the  head.  The  tail  is  twice  as  long  as  the  body,  head  included. 
The  total  length  of  the  specimen  is  727  millimeters,  including  I  he  nasal  tip,  which  measures 
7  millimeters. 

Lateral  line  highly  specialized,  with  numerous  pores,  corresponding  in  general  charac- 
ter to  those  upon  the  head,  and  arranged  in  a  deep  furrow,  fcheir  distances  apart  being  about

the  same  as  in  the  case  of  those  upon  the  head.  Height  of  dorsal  and  anal  fins  about  equal 
to  half  the  height  of  body. 

Color,  apparently,  brownish;  peritoneum  black. 

The  types  of  V.  procera  were  two  fishes  obtained  at  station  325,  N.  lat.  33°  35'  20",  W.  Ion. 
76°,  at  a  depth  of  047  fathoms.  Another  mutilated  specimen,  about  190  millimeters  long, 
was  taken  at  station  327.  This  species  is  in  many  respects  closely  allied  to  the  Nettastoma 
melanurum  of  the  Mediterranean,  but  appears  to  differ  from  it  in  the  greater  length  of  the  tail, 
the  much  smaller  teeth,  and  in  the  presence  of  a  filamentous  nasal  tip. 

VENEFICA  PROBOSCIDEA,  (Vaillant),  Jordan  and  Davis 
Nettastoma proboscideum,  Vaillant,  Exp.  Sci.,  Travailleur  et  Talisman,  Poissons,  1888,89,  pi.  vn,  fig.  3. 

A  Xettastoma,  with  upper  jaw  projecting  quite  beyond  the  lower,  and  prolonged  in  a 
proboscis  like  tip  half  as  long  as  the  upper  jaw  and  5  times  the  diameter  of  the  eye,  with 
mouth  cleft  extending  far  behind  the  orbit.  Teeth  small,  in  cardiform  bauds  on  jaws  and 
palatines.  Tail  one-half  to  three-fifths  the  length  of  body  (head  included).  Diameter  of  the 
eye  one-twentieth  the  length  of  the  head. 

This,  described  from  a  single  specimen  obtained  off  Morocco,  at  2,200  meters,  is  a 
small-eyed  form,  with  fine  teeth  and  a  nasal  extension.  The  length  of  the  nasal  tip  is, 
essentially,  an  unreliable  character,  and  the  proportion  of  tail  to  body  may  prove  to  be  sub- 
ject to  considerable  individual  variation.

A  genus  closely  allied  to  Nettastoma,  having  the  nostrils  lateral,  the  posterior  one 
slit  like  and  placed  near  the  eye.  Body  scaleless.  Snout  much  produced.  .Taws,  vomer, 
and  palatine  bones  with  several  series  of  small,  pointed  teeth,  those  along  the  median  line 
of  the  vomer  being  somewhat  the  larger.  Vertical  fins  well  developed;  pectorals  none. 
Nostrils  lateral,  the  anterior  near  to  the  end  of  the  snout,  the  posterior  in  front  of  the 
eye.    Air  bladder  and  pyloric  appendages  absent.     (Peters.)

Saurenchelys  cancrivora,  Peters,  loc.  <■;/. — GCnther,  Cat.  Fish.  Brit.  Mas.,  vni,  48. 

Tail  tapering  into  a  point.  Gill  opening  one -fifth  more  distant  from  vent  than  from  the 
end  of  the  snout.  Diameter  of  eye  one-third  of  the  length  of  the  snout.  Length  of  head 
two-fifths  of  total  length.  Dorsal  fin  commencing  immediately  behind  the  gill  opening. 
Upper  jaw  the  longer.  Vertical  fins  with  a  black  margin  posteriorly.  Peritoneum  silvery. 
( Peters.) 

The  unique  specimen  from  which  the  above  characters  were  taken  was  found  by  Dr. 
Peters,  in  the  Berlin  Museum  in  a  jar  of  fishes,  chiefly  from  India.  A  crab  found  iu  the 
stomach  led  Dr.  Peters  to  believe  that  the  fish  had  been  misplaced,  and  actually  had  come 
from  the  Mediterranean  or  the  Atlantic.  Its  resemblance  to  Nettastoma  and  the  fact  that 
it  is  not  known  in  any  shallow- water  fauna  lead  us  to  believe  that  it  is  probably  a  deep- 
water  form.

Head  comparatively  stout,  its  depth  one-seveuth  its.  greatest  length.  Eye  moderate, 
less  than  one-third  the  length  of  the  head  without  snout.  Length  of  pectoral  fins  slightly 
less  than  height  of  the  anal,  which  is  less  than  the  height  of  the  body  and  rather  more  than 
the  greatest  depth  of  the  head.  Pale  above,  belly  and  anal  fin  blackish,  the  color  not 
abruptly  chauging,  the  back  somewhat  speckled. 

This  most  remarkable  species  was  first  obtained  by  H.  M.  S.  Samarang  in  the  South 
Atlantic  in  1846,  and  a  little  later  by  the  indefatigable  Lowe  at  Madeira.  In  1879,  when  the 
Fish  Commission  had  its  headquarters  at  Gloucester,  a  third  specimen  was  obtained  by  us 
from  a  George's  Bank  fisherman,  who  had  preserved  it  in  a  whisky  bottle,  and  who  was 
induced  to  part  with  it  in  barter  for  a  five-dollar  bill. 

In  1881,  the  Fish  Hawk  while  at  work  in  2~>-  fathoms  off  Newport,  brought  up  a  small 
specimen,  clinging  by  its  long  jaws  to  the  outside  of  the  trawl  net.  Since  then,  the  Alba- 
tross and  the  Blake  have  obtained  numerous  specimens,  off  the  South  Atlantic  coast  in  300 
to  1,000  fathoms.  Vaillant  has  a  magnificent  specimen,  650  millimeters  long,  obtained  in 
1888  meters  on  the  Banc  d'Arguin.     The  Challenger  did  not  obtain  a  single  specimen. 

The  following  is  a  list  of  localities  whence  this  species  has  been  obtained  by  the  Alba- 
tross :

The  ridges  that  bound  the  median  rostral  sulcus  converge  and  form  a  carina  along  the 
median  Hue  in  vertical  from  the  anterior  border  of  the  orbit.  The  greatest  height  of  the 
body  (at  posterior  third)  of  the  type  specimens  (0.447  meter  long)  is  0.013  meter,  and  the

CYEMA,  Giinther. 

Cyema,  Gunther,  Ann.  and  Mag.  Nat.  Hist.,  n,  1878,251;  Challenger  Report,  xxn,  1887,  265. — Jordan  and 
Davis,  Rep.  U.  S.  F.  C,  1888,  65. 

Tbis  genus,  says  Giinther,  combines  tbe  form  of  the  snout  of  a  Xrmii-hthi/s  with  the 
soft,  short  body  of  a  Leptocephalus;  but  tbe  gill  openings  are  very  narrow  and  close  together 
on  tbe  abdominal  surface.  Vent  in  about  tbe  middle  of  the  length  of  the  body;  vertical  fins 
well  developed,  confined  to  and  interrupted  at  the  extremity  of  the  tail.  Pectoral  fins  well 
developed.     Eye  very  small. 

It  is  to  be  hoped  that  Dr.  Giinther  will  publish  his  views  more  fully  upon  the  relation 
of  this  form  to  Leptocephalus.  To  a  casual  observer  Cyema,  as  exhibited  in  the  French  and 
English  material,  seems  very  like  a  young  N~emichthys,  with  its  jaws  and  tail  mutilated  and 
partly  repaired.

A  specimen  4A  inches  longwas  obtained  by  the  Challenger  in  the  South  Pacific,  station 
215,  depth  1,500  fathoms;  another,  4§  inches  long,  at  station  158,  in  the  Antarctic  seas, 
depth  1,800  fathoms.  The  French  explorers  took  another,  identified  by  Vaillant  with  this 
species,  at  station  xxxvin,  2,210  meters,  off  the  coast  of  Morocco.  This  specimen  is  thus 
described  by  Vaillant : 

This  is  a  little  fish,  110  to  120  millimeters  long  and  scarcely  2i  to  •'!  millimeters  in  thick- 
ness; this  form  has  justly  been  compared  to  Leptocephalus  by  the  accomplished  Keeper  of 
the  Zoological  Collections  in  the  British  Museum. 

The  head  is  swollen,  forming  about  one-sixth  of  the  total  length;  the  muzzle  forms 
more  than  a  half  of  the  bead;  the  angle  of  the  mouth  is  well  behind  the  eye;  the  jaws  are 
armed  with  small  serrated  teeth  disposed  in  quincunx  and  giving  it  the  appearance  of 
a  fine  file  as  in  Nemichthys.  The  upper  jaw  is  in  large  part  wanting,  also  the  extremity  of 
the  lower  and  their  dimension  can  only  be  given  approximately.  It  is  not  possible  to  dis- 
cover the  position  of  the  nostrils.  The  eyes  are  small  and  the  interorbital  space  rather 
large,  about  one-seventh  of  the  length  of  the  head.  The  narrow  branchial  orifices  are  close 
to  the  lateral  line,  but  not  confluent,  and  placed  very  near  tbe  pectorals. 

The  anus  is  situated  behind  the  middle  of  the  total  length,  at  the  union  of  the  anterior 
five-eighths  with  the  posterior  three-eighths.     The  skin  is  scaleless. 

The  dorsal  and  anal  are  nearly  opposite,  on  the  posterior  part  of  the  body,  immediately 
behind  the  anus.  The  manner  in  which  these  fins  terminate  is  not  quite  clear;  in  the  living 
animal  it  appears  to  me  that  they  are  united,  forming  a  semi-lunar  fork,  posteriorly  wanting 
the  ordinary  caudal  fin  of  fishes  properly  so  called,  but  I  am  not  willing  to  affirm  that  the 
extremity  was  absolutely  intact,  the  action  of  the  preserving  fluid  making  the  ascertain- 
ment of  tbe  tact  more  difficult  daily. 

The  color  is  a  beautiful  velvety  black.

The  specimen  is  jSTo.  84-1007,  in  the  ichthyological  collection  of  the  Paris  Museum.  It

3,743  and  3,202  meters  in  the  Pacific  and  Antarctic  oceans. 


DISCUSSION   OF   SPECIES   AND   TIIKIK    DISTRIBUTION.  155

and  Davis,  Rep.  I",  s.  r.  C,  1888,  653. 

Neiiiichthyids  with  a  rectilinear  occipito-rostral  outline,  with  very  attenuated  jaws, 
high  mandibular  rami,  the  branchial  apertures  nearly  confluent,  enlarged  acute  conic  teeth 
in  a  median  row  on  the  vomer,  and  with  a  silverj  epidermis,  and  a  filiform  tail.  (Oill  and 
Ryder.)

The  rays  are  ensheathed  in  a  tough  membrane  which  renders  it  impossible  at  present 
to  enumerate  them  with  exactitude.  They  are,  however,  it  is  to  be  noted,  more  distant 
from  each  other,  and  consequently  fewer  than  in  Serrivomer. 

The  tish  has  a  silvery  sheen  by  which,  as  well  as  by  the  smaller  eyes  and  deeper  mandi- 
bles, it  may  be  at  once  recognized  from  its  relations. 

This  is  the  smallest  of  the  family,  but  a  beautiful  silvery  form.  The  total  length  of 
the  only  specimen  found  is  0.13  of  a  meter,  and  its  greatest. height  (at  the  branchial  region) 
is  0.0025  meter.    ( Gill  and  Ryder.) 

A  single  specimen  (Cat.  No.  33293,  U.  S.  X.  M.)  was  obtained  by  the  Albatross  at  station 
2039,  in  38°  19'  26"  X.  bit.,  68°  20'  20"  W.  Ion.,  at  a  depth  of  2,361  fathoms.

The  description  of  this  species  given  by  Giinther  (Preliminary  notice  1873,  p.  251) 
being  very  brief,  the  example  dredged  from  the  Talisman,  on  the  other  hand,  leaving  much 
to  be  desired  in  the  way  of  preservation,  the  affinity  is  doubtful. 

The  example,  moreover,  if  we  may  be  able  to  judge,  is  a  Little  more  nearly  cylindrical 
in  form.  The  muzzle  is  sharply  conical,  the  teeth  of  the  jaws  rasp-like,  similar  to  those  of 
Nemichtlvys  scolopaceus,  Richardson.  The  eye  appears  small,  nearer  to  the  extremity  of  the 
snout  than  to  the  branchial  orifice.

DEEP-SEA    FISHES   OF   THE    ATLANTIC    BASIN. 


The  vent  is  placed  a  little  farther  back  than  in  the  typical  species  of  the  genus;  the 
length  of  the  tail,  compared  to  the  total  length,  is  in  that  more  than  ten-elevenths  and 
only  seven-ninths  in  the  individual  here  described.  The  skin  being  for  the  greater  part  re- 
moved, together  with  a  portion  of  the  fius,  some  important  characters  are  wanting.  I  find 
no  trace  of  the  dorsal,  except  au  incomplete  ray,  which  is  a  little  behind  the  anus;  the  anal 
commences  immediately  behind  this  last.  It  appears  to  have  been  higher  than  the  dorsal. 
The  base,  moreover,  of  the  scapular  bone,  which  supports  the  pectorals,  alone  enables  us  to 
determine  the  location  of  these  fins  behind  the  branchial  aperture.

"We  find  the  principal  character  given  to  this  species  by  Dr.  Vaillant  to  be  the 
insertion  of  the  anus  at  a  distance  from  the  pectorals  double  that  which  separates  the 
pectorals  from  the  eye.  As  for  the  proportional  elongation  of  the  body,  which  is  greater 
in  the  Nemichthys  scolopaceus,  Richardson,  than  in  Xemichthys  infant,  Giinther,  in  our  exam- 
ple the  difference  is  less  marked. 

Serrivomer  Richardii  is  represented  as  having  the  eye  one  twenty-fifth  of  the  length  of 
the  head;  in  8.  Beanii  the  eye  is  much  larger,  forming  more  than  one-twentieth  of  the 
length  of  the  head.  In  8.  Richardii  the  origin  of  the  dorsal  fin,  if  correctly  represented, 
is  distant  from  the  gill-opening  a  space  nearly  equal  to  the  length  of  the  head,  while  in  8. 
Beanii  its  distance  from  this  point  equals  the  length  of  the  head.  The  gape  of  the  mouth 
also  in  S.  Richardii  is  apparently  much  wider  than  in  8.  Beanii,  the  angle  of  the  mouth 
being  well  behind  the  vertical  through  the  eye  in  8.  Bichardi  and  below  the  posterior  mar 
gin  of  the  eye  in  8.  Beanii. 

Serrivomer  Richardii  was  taken  at  station  131  of  the  Talisman,  off  the  Azores,  at  a 
depth  of  2,995  meters.

Both  jaws  are  armed  with  slender,  curved,  widely  set  teeth,  irregularly  uniserial  orbiserial, 
their  points  being  directed  inward.  The  length  of  the  jaws  is  from  one-third  to  one-seventh 
of  the  length  of  the  body;  that  is,  the  distance  from  the  vent  to  the  extremity  of  the  snout. 
The  dorsal  fin  commences  a  long  way  behind  the  head  and  a  short  distance  in  front  of  the 
vent;  like  the  anal  it  may  or  may  not  reach  the  end  of  the  tail,  which  terminates  in  an 
extremely  delicate  and  thin  filament.  The  small  pectoral  tin  with  some  thirty  very  thin 
rays.  Gill-opening  an  elongate  slit.  A  bluish-white  line  runs  on  the  back  along  each  side 
of  the  base  of  the  dorsal  fin,  and  a  similar  line  is  sometimes  distinct  along  the  anal  fin. 
(Oiinther.) 

Of  this  genus  five  specimens  have  been  captured;  described  by  Dr.  Gunther  as  follows. 
There  may,  of  course,  be  two  species,  for  it  is  not  certaiu  that  Mitchill  and  Harwood  both 
saw  the  same  form. 


153  DEEP-SEA   FISHES    OF   THE    ATLANTIC    BASIN. 

(1)  The  fish  described  by  Mitchill  in  1824,  which  was  taken  in  52°  K  lat.,  30°  W.  Ion.; 
it  was  discovered  afloat  in  a  helpless  condition,  having  swallowed  a  fish  10  inches  long.  The 
body  of  this  specimen  was  11  and  the  tail  58  inches  long.  It  does  not  seem  to  have  been 
preserved. 

(2)  The  fish  described  by  Harwood  in  1827,  which  was  taken  in  62°  N.  lat.,  57°  W.  Ion. ; 
it  was  discovered  afloat  in  a  helpless  condition,  "almost  worn  out  by  unavailing  efforts  to 
gorge  a  fish  of  about  7  inches  in  circumference."  This  is  the  largest  of  the  specimens  known, 
its  body  having  been  about  20  and  the  tail  34  inches  long.  It  does  not  seem  to  have  been 
preserved. 

(3)  The  fish  described  by  Johnson  in  18G2,  which  was  taken  off  Madeira,  under  what 
circumstances  Johnson  could  not  learn,  but  probably  also  floating  on  the  surface;  it  had 
swallowed  another  deep-sea  fish  about  9  inches  long  (Halargyreus  Johnsonii),  the  stomach  of 
which  was  forced  up  into  the  mouth  by  the  distended  air  bladder,  showing  how  rapidly  both 
fishes  must  have  ascended  to  the  surface.  The  body  of  this  specimen  is  8J  and  the  tail  23 
inches  long.    It  is  preserved  in  the  British  Museum. 

(4)  A  young  specimen  in  the  British  Museum,  the  history  of  which  is  unknown;  its 
body  is  3,  its  tail  8i  inches  long.  It  is  much  shriveled,  having  been  preserved  for  a  long 
time,  but  supplies  some  valuable  information  on  points  in  which  the  larger  is  imperfect. 

(5)  A  single  badly  mutilated  specimen,  secured  by  the  Blake  from  station  cccxxxi,  in 
35°  44'  40"  E".  lat.,  74°  40'  20"  W.  Ion.,  at  a  depth  of  898  fathoms. 

Dr.  Giinther's  description  applies,  no  doubt,  to  S.  ampullaceus.  His  figure  is  repro- 
duced in  our  figure  178. 

Family  EURYPHARYNGID^.

Vai.liant,  Exp.  Sci.  Travailleur  et  Talisman,  1888,  193. 

Lyomeri  with  the  branchio-anal  portion  much  shorter  than  the  rostro-branchial;  with 
the  tail  very  elongated  and  moderately  attenuated  backwards ;  the  head  flat  above,  and  with 
a  transverse  rostral  margin,  at  the  outer  angles  of  which  the  eyes  are  exposed;  with  the 
palatine  jaws  excessively  elongated  backwards  and  the  upper  parallel,  and  closing  against 
each  other  as  far  as  the  articulation  of  the  two  suspensorial  bones ;  with  minute  teeth  on 
both  jaws;  the  dorsal  and  anal  fins  well  developed  and  continued  nearly  to  the  end  of  the 
tail,  and  with  minute,  narrow  pectoral  fins. 

The  mandibular  rami  are  exceedingly  narrow  and  slender,  but  the  jaws  are  extremely 
expansible  and  the  skin  is  correspondingly  dilatable;  consequently  an  enormous  pouch  may 
be  developed.  Inasmuch  as  the  slenderness  and  fragility  of  the  jaws  and  the  absence  of 
raptorial  teeth  (at  least  in  Gastrostomies)  preclude  the  idea  of  the  species  being  true  fish  of 
prey,  it  is  probable  that  they  may  derive  their  food  from  the  water  which  is  received  into 
the,  pouch,  by  a  process  of  selection  of  the  small  or  minute  organisms  therein  contained. 

The  peculiar  closure  of  the  anterior  half  of  the  upper  jaws  upon  each  other,  and  the 
coordinate  joint  between  the  hyomaudibular  and  quadrate  elements  of  the  suspensorium 
are  doubtless  correlated  with  the  mode  of  ingestion  or  selection  of  food.  The  skin  consti- 
tuting the  pouch,  it  may  be  added,  has  a  peculiar  velvety  appearance,  and  also  reminds 
one  of  the  patagium  or  wing  membrane  of  a  bat.     ( G ill  and  Ryder.)

Both  jaws  possess  merely  t'eelile  dental  granulations,  but  the  lower  jaw  is  armed  in  front 
with  a  pair  of  slender  curved  teeth  (2  millimeters  long).  The.  length  of  the  jaws  is  about 
one-half  of  that  of  the  body.  The  origin  of  the  dorsal  tin  is  nearer  to  the  end  of  the  snout 
than  to  the  vent;  neither  the  dorsal  nor  the  anal  tin  reach  the  end  of  the  tail  (which  termi- 
nates in  a  small,  skinny  lobe).  (Hll-opening  a  very  small  round  opening.  No  bluish-white 
line  along  the  back.     (GHmther.) 

"  This  animal,"  writes  Grill,  "is  about  0.47  meter  long  and  0.02  meter  high  at  the  most 
elevated  part  and  is  of  au  intense  deep-black  color.  The  body,  the  form  of  which  is  masked 
in  front  by  the  abnormal  mouth,  which  will  be  mentioned  further  on,  resembles  that  of 
jUacrurm;  it  becomes  regularly  attenuated  from  about  the  anterior  fourth,  the  point  at 
which  the  external  branchial  orifice  is  seen,  and  terminates  in  a  point  at  the  caudal  extrem- 
ity;  the  anus  is  situated  at  the  junction  of  the  anterior  third  with  the  posterior  two-thirds 
of  the  body. 

"What  gives  this  fish  a  very  peculiar  physiognomy  is  the  arrangement  of  the  jaws  and 
the  structure  of  the  mouth,  which  are  even  au  exaggeration  of  what  Mr.  Ayres  has  described 
in  Malacosteus  niger.  Although  the  head  is  short  (scarcely  0.03  meter),  the  jaws  and  the 
suspensoriuin  are  excessively  elongated;  the  latter  did  not  measure  less  than  0.095  meter; 
and  from  this  it  results  that  the  articular  angle  is  carried  very  far  back,  to  a  distance  from 
the  end  of  the  muzzle  equal  to  about  3i  times  the  length  of  the  cephalic  portion."

The  cranium  forms  about  one-thirtieth  or  less  of  the  extreme  length,  and  is  as  broad  as 
long;  the  jaws  are  excessively  elongated,  being  nearly  (in  large)  or  more  (in  young)  than 
7  times  longer  than  the  cranium;  there  are  about  100  rays  in  the  dorsal  fin  and  about 
107  in  the  anal;  the  pectorals  are  very  small,  being  only  about  as  long  as  the  diameter  of 
the  eye,  and  little  more  than  twice  as  long  as  wide  at  the  base,  and  have  about  nine  simple 
rays.  The  rays  of  the  unpaired  tins  are  quite  flexible  in  the  small  individuals,  but  quite 
rigid  and  more  perfectly  ossified  in  the  larger;  they  become  obsolete  toward  the  end  of  the 
tail.  The  rays,  which  are  rigid  and  well  ossified  anteriorly,  become  shorter,  very  slender, 
and  flexible — in  fact,  almost  as  limp  as  threads  near  the  end  of  the  tail.  The  vertebral 
bodies  become  longer  and  more  attenuated  toward  the  end  of  the  tail.

fins,  and  submedian  anus.  Scales  absent,  the  skin  being  perfectly  smooth.  Lateral  line 
commencing  on  the  side,  behind  the  head,  near  the  back,  but  submedian  behind. 

Head  oblong,  oval.  Eyes  in  the  anterior  half  of  the  head.  Nostrils  lateral,  in  front  of 
the  eyes;  neither  tubular.  Mouth  with  the  cleft  little  oblique,  extending  behind  the  eyes. 
Jaws  well  developed,  mamillaries  approximated  to  the  front  of  the  vomer  and  attenuated 
backwards.  Mandible  moderately  stout;  the  dentary  with  the  coronoid  process  moderate

DERICHTHYS  SEKPENTINUS,  Gill.     (Figure  169.) 
Derichthys  serpentinus,  Gill,  American  Naturalist,  xvm,  1887,433. 

Body  stout,  somewhat  compressed,  especially  behind  the  vent;  its  greatest  height  in 
the  region  of  the  vent  nearly  equal  to  the  length  of  the  head;  its  postanal  portion  equal  to 
the  distance  from  the  vent  to  the  posterior  margin  of  the  orbit. 

Head  small,  snake-like,  its  resemblance  to  that  of  a  serpent  being  enhanced  by  the  con- 
tracted neck-like  appearance  of  the  anterior  portion  of  the  body.  Its  anterior  portion  is 
depressed,  and  the  view  from  above  abruptly  truncate,  the  width  of  the  tip  of  the  snout 
being  considerably  greater  than  the  interorbital  space.  The  lower  jaw  is  narrower  ami  in 
eluded,  the  upper  jaw  projecting  beyond  its  tip  a  distance  nearly  equal  to  the  diameter  of 
the  eye.  The  length  of  the  snout  is  one  third  that  of  the  head.  The  cleft  of  the  mouth  ex- 
tends behind  the  eye  a  distance  equal  to  or  slightly  greater  than  the  diameter  of  the  orbit.

162  DEEP-SEA    FISHES    OF   THE    ATLANTIC    BASIN. 

Nostrils  elongate,  the  exterior  slit  occupying  the  middle  third  of  the  space  between  the  an- 
terior margin  of  the  orbit  and  the  tip  of  the  snout.  Length  of  the  neck  four-fifths  that  of 
the  head,  equal  to  the  distance  from  the  posterior  limit  of  the  nostril  to  the  posterior  por- 
tion of  the  head.  Pectorals  inserted  high  up,  almost  in  median  line,  and  composed  of  two 
or  three  flexible,  filiform  rays.  Origin  of  the  dorsal  about  midway  between  the  vent  and 
the  tip  of  the  snout,  the  fin  composed  of  flexible,  delicate  rays,  not  sufficiently  differentiated 
from  the  thin  membrane  as  to  be  easily  counted,  those  rays  being  longest  in  the  region  above 
the  vent. 

Vent  nearly  median.  Anal  fin  beginning  immediately  behind  the  vent,  and  similar  in 
height  and  appearance  to  the  dorsal  fin,  which  it  apparently  joins  at  the  tip  of  the  tail. 
No  ventrals. 

Lateral  line  inconspicuous,  with  minute  pores,  though  its  location  is  emphasized  by 
the  Amphioxus  like  arrangement  of  the  muscular  fibers.  Length  of  type  8  inches;  of  head, 
one-half  inch;  of  region  in  advance  of  pectorals,  1  inch;  greatest  height,  seven-sixteenths

Notacanthi,  Bleeker,  Tentamen,  1859,  xxm  (in  part). 
Heteromi,  Gill,  American  Naturalist,  Nov.,  1889,  1016. 

Teleosts  with  the  scapular  arch  formed  by  the  proscapula  and  post  temporal  (or  postero- 
temporal),  the  latter  detached  from  the  sides  of  the  cranium  and  impinging  on  the  supraoc- 
cipital;  the  hypercoracoid  and  hypocoracoid  coalesced  into  a  single  lamellar  imperforate 
plate;  the  actiuosts  normal;  the  cranium  with  the  condyle  confined  to  the  basioccipital 
(ill  defined);  the  exoccipitals  coalesced  with  the  epiotics  and  opisthotics;  the  vomer 
obsolete;  the  opercular  apparatus  complete,  but  the  preoperculum  slightly  connected  with  or 
discrete  from  the  suspensorium;  the  suborbitals  suppressed;  the  jaw  bones  complete  and 
little  aberrant;  the  palatines,  entopterygoids,  aud  ectopterygoids  well  developed;  the 
anterior  vertebras  separate,  and  the  ventrals  abdominal.     (Gill.) 

All  the  heteromous  teleosts  have  a  subfnsiform,  moderately  compressed  body  with  head 
short  and  snout  protruding,  sometimes  produced,  proboscis-like  (as  in  Polyacanthonotus).

Mouth  moderate,  transverse,  inferior.  Lower  jaw  normal,  with  rami  immovably  con- 
nected at  symphysis.  Scales  small  on  body  and  head;  lateral  line  present.  Teeth  slender, 
closely  set,  in  single  series  in  each  jaw.  Gill  openings  wide,  the  membranes  separate  and 
free  from  the  isthmus. 

Dorsal  fin  median,  with  short  and  free  dorsal  spines,  and  with  only  one  ray  (if  any) 
behind.  Anal  fin  long,  rather  high,  extending  from  the  middle  of  the  body  to  tbe  caudal, 
with  which  it  unites,  and  with  numerous  spinous  rays.  Ventrals  abdominal,  often  con- 
fluent,with  1-5  spines  and  1-8  soft  rays.    Pectorals  short  and  high  up.    Pseudobranchia^  none. 

The  elaborate  anatomical  description  of  Xotacanthus  sexspinis,  given  by  Giinther  (Chal- 
lenger Report,  xxn,  213-8)  with  numerous  excellent  figures,  applies  in  its  general  features 
to  all  the  members  of  this  family.  In  the  discussion  of  the  genera  and  species  below,  little 
attention   has  been  given  to  the  degree  of  connection  of  the  ventral  fins.    In  every  in-

stance  they  are  connate  or  continent,  but  the  degree  of  connection  depends  not  so  much 
upon  their  proximity  to  each  other  as  upon  bhe  extent  of  the  connecting  membrane  in  the 
several  forms, and  we  question  whether  the  character  can  be  so  defined  as  to  serve  even  for 
specific  distinctions.  All  the  species  examined  by  us  have  the  peculiar  modifications  of  the 
posterior  extremities  of  the  maxillary,  and  the  sharp  spine  more  or  less  hidden  by  the  fleshy 
fold  of  the  lips  at  the  angle  of  the  month  on  either  side.

Head  and  body  much  compressed,  the  body  elongate,  snout  obtuse,  rounded  at  its  tip, 
not  proboseis-like.  The  cleft  of  the  mouth  inferior.  Dorsal  fin  almost  rudimentary,  con- 
sisting of  12-15  very  short,  flexible  spines,  remote  from  each  other  and  not  connected  by 
a  membrane.  Anal  fin  very  long,  its  origin  close  behind  the  vent,  which  is  situated  nearly 
midway  of  the  length  of  the  body;  its  anterior  portion  is  composed  of  separate,  tlexible 
spiues,  without  membrane,  resembling  those  of  the  dorsal;  these  gradually  lengthen, 
grading  into  the  articulated  branched  rays.  No  caudal.  Ventrals  broad,  with  broad, 
peduncle-like  bases,  closely  contiguous,  separated  only  by  a  slight  groove  at  the  base,  situ- 
ated near  the  vent.  Teeth  acicular,  in  single  row  upon  maxillaries,  in  a  double  row  upon 
mandibulars,  villiform  and  in  double  row  upon  the  palatines.  Scales  very  numerous,  of

Notacanthus  sexspinis,  Richardson,  as  figured  by  Giiuther  in  the  Challenger  Report,  has 
8  dorsal  spines  (the  last  with  supplementary  ray),  instead  of  the  <>  indicated  by  its  specific 
name;  and  this  is  the  case  also  with  the  New  Zealand  specimen  in  the  National  Museum, 
preseuted  by  Dr.  Gunther,  and  one  from  Cook  Strait,  New  Zealand,  in  the  Museum  at  Flor- 
ence, which  is  410  millimeters  in  length,  and  has  a  radial  formula:  D.  8;  A.  13  126;  P.  12: 
V.  1/8;  Co.  These  specimens  do  not  show  the  inflation  of  the  checks,  figured  in  Dr. 
Gunther's  plate. 

The  results  of  Dr.  Giinther's  dissections  seem  to  indicate  thai  this  species  at  least  of 
Notacanthus  does  not  live  at  a  very  great  depth.

A  Notacanthus  with  elongate  body,  whose  greatest  height  lies  between  the  pectoral  and 
ventral  tins  and  is  contained  about  41  times  in  the  distance  from  the  vent  to  the  tip  of  the 
snout.  Head,  short,  compressed,  its  length  not  quite  3h  times  in  distance  from  vent  to  snout. 
Mouth  large,  extending  backward  to  a  point  nearly  under  the  eye,  the  maxillary  nearly 
to  the  vertical  from  the  anterior  margin  of  pupil.  The  mouth  does  not  lie  entirely  on  the 
under  portion  of  the  head,  but  is  sublateral.  There  are  35  teeth  in  the  intermaxillaries  on 
each  side.  The  distance  between  the  upper  profile  of  the  head  and  the  eye  is  about  equal 
to  the  diameter  of  the  eye,  ami  the  diameter  is  slightly  greater  than  one-third  the  length  of 
the  snout  (certainly  not  more  than  one-half  the  length  of  the  snout),  and  about  one-eighth 
the  length  of  the  head.  (In  this  connection,  it  is  taken  for  granted  that  the  hole  in  the  skin 
of  the  head  represents  the  size  of  the  eye:  if,  however,  we  assume  that  the  entire  portion 
free  of  scales  is  the  eye,  the  diameter  is  greater  and  equal  to  one-sixth  the  length  of  the  head. 
It  is,  at  any  rate,  considerably  less  than  the  width  of  the  interorbital  space.)  The  gill  cover 
appears  to  be  divided  to  below  the  symphysis  of  the  operculum  (with  hyomandibular),  and 
is  free  from  the  isthmus  (the  entire  under  portion  of  the  head  is  cut  open  in  the  middle). 

Scales  are  lacking  only  about  the  mouth  and  eyes;  about  40  longitudinal  rows  of 
small  scales  (2  millimeters  broad.  4  millimeters  long)  between  the  ventral  outline  and  the 
lateral  line;  smooth,  and  imbricated. 

Of  the  11  dorsal  spines,  the  first  (overlooked  by  Bloch  and  Valenciennes)  is  very  small 
and  only  visible  as  a  point;  placed  close  to  this  (1  millimeter)  is  the  second,  which  is  also 
very  short  and  feeble.  The  third,  though  also  short,  is  thicker.  The  vent  lies  behind 
the  fifth  spine.  Of  the  15  anal  spines,  which  have  their  origin  immediately  behind  the 
vent,  the  first  (overlooked  by  Bloch  and  Valenciennes)  is  very  small;  it  does  not  extend 
beyond  the  profile;  the  second  and  third  but  slightly.  The  spines  which  are  longest  and 
placed  farthest  back  still  bear  traces  of  a  connecting  membrane  and  are  probably  only 
worn-off  rays.  The  pectorals  are  inserted  somewhat  farther  back  from  the  gill  covers  than 
shown  by  Bloch;  the  end  is  surely  broken  off,  but  yet  it  can  hardly  be  doubted  that  this 
fin  is  too  long  in  Bloch's  figure;  its  base  is  less  than  one-sixth  the  length  of  the  head. 
The  ventral  fins,  connected  behind  the  median  line  by  a  membrane,  terminate  considerably 
in  advance  of  the  vent  (they  are  apparently  worn  off  a  little  behind). 

Radial  formula:  D.  xi;  A.  15  +  118  C.  ?;  P.  19;  v,  3  +  7  (1),  8  (r).— Branchiostegals,  vm, 
(r)-ix  (1). 

Total  length  (restored)  85  centimeters.  Length  of  head  about  10.7  centimeters. 
Height  of  body  about  8  centimeters.    Length  of  tail  about  47.5  centimeters. 

The  full  diagnosis  given  above  was  furnished  by  our  friend  Dr.  Franz  Hilgendorf,  Cus- 
tos  of  the  zoological  collections  in  the  Royal  Museum  of  Natural  History,  Berlin,  who 
also  gave  the  following  notes  on  the  present  condition  of  the  types:

DISCUSSION   OF   SPECIES   AND    THEIR    DISTRIBUTION.  165 

Besses  in  addition  to  this  only  a  single  specimen  of  Notaeanthus — Wotac.  sexspinis),  but  it  is 
in  a  very  unsatisfactory  condition.  It  was,  perhaps,  injured  in  transportation  from  Paris. 
The  jar  lias  not  been  opened  for  more  than  thirty  years.  Very  likely  Blocb  received  ii  in  a 
poor  state  of  preservation — a  large  cavity  in  the  belly,  between  the  pectorals  and  ventrals,  a 
dilapidated  left  cheek,  injured  eyeballs,  intestines  wanting,  etc.     In  addition  to  this,  there 

are  other  defects  of  a  later  date,  such  as  the  loss  of  the  caudal,  the  tip  of  the  snout,  the 
macerati f  the  frontal  bones.  The  gill  arch  is  almost  entirely  gone:  the  intestines  alto- 
gether. The  frontal  bone  is  crushed  and  the  first  vertebra  is  disconnected.  There  is  a  long 
gap  in  the  dorsal  tin. 

The  actual  length  is  now  82  centimeters;  in  addition  to  tins  should  be  added,  at  the 
most,  1  centimeter  for  the  snout  and  §  centimeter  for  the  caudal  tin.  This  makes  its  former 
length  about  85  centimeters.  (Bloch  says  2A  feet ;  this  would  lie,  according  to  the  Rhenish 
\i.  i.  Prussian]  measure, only 78J  centimeters.  Perhaps  Bloch  used alonger foot, or  hegave 
only  an  approximate  measurement.)  As  we  have  no  other  specimen  which  we  might  have 
.•on  founded  with  that  of  Bloch,  and  ours  still  bears  the  label  (apparently  in  Troschel's  hand- 
writing) "ITotacanthus nasus,  Iceland,  Bloch,"  1  have  no  doubt  that  No.  140!)  is  the  type 
specimen.     Nor  can  there  have  been  another  in  Paris. 

How  much  of  the  end  of  the  caudal  is  missing  is  difficult  to  say.  The  point  of  the  frac- 
ture is  hard  and  the  fin  bones  are  soft.  1  f  Valenciennes's  account  is  accurate,  the  caudal  fin 
only  is  missing,  and  one  or  two  rays  of  this  are  still  attached.  If  Bloch's  description  is  cor- 
rect, there  were  14!) — (13+8  or  10 ?)=126-128  rays  in  the  anal:  consequently,  a  caudal  end, 
with  at  least  10  rays,  in  addition  to  the  caudal  tin,  was  lost,  and  the  fish  would  have  been 
somewhat  longer  than  85  centimeters.    1  presume  there  was  an  oversight  on  Bloch's  part. 

The  material  now  classed  by  authors  under  the  name  of  N.  nasus  is  the  following: 
(1)  A  specimen  described  by  Fabricius  in  1798  under  the  generic  name  of  Campylodon, 
obtained  in  1704  from  Greenland:  (2)  Bloch's  type  in  the  Berlin  Museum,  believed  by  him 
to  come  from  the  West  Indies,  described  under  the  names  N.  Ghemnitzii  (?),  N.  nasus,  and 
Acanthonotus  nasus;  (3)  A  specimen,  obtained  off  Iceland  by  La  Recherche  and  brought  by 
Gaimard  to  the  Paris  Museum,  figured  in  the  Eegne  Animal,  and  said  to  have  been  figured 
also  in  the  Voyage  in  Scandinavia.  This,  as  has  already  been  stated,  is  possibly  a  typical 
V.  nasus;  (4)  A  specimen,  ■'!  feet  long,  obtained  in  South  Greenland,  and  brought  in  1S77  to  the 
Copenhagen  Museum.    This  also  is  possibly  not  a  characteristic  representative  of  the  species. 

Both  Canestrini  and  Giglioli  enumerate  Notacanihus  nasus  among  Mediterranean  fishes, 
but  entirely  without  authority.

A  N~otacanthus,  with  its  body  much  higher  over  ventrals  than  over  pectorals,  and  com- 
paratively short,  its  height  equal  to  one-third  of  the  distance  from  the  vent  to  the  tip  of 
the  snout,  and  nearly  equal  to  the  length  of  the  head,  the  lateral  line  arcuate  in  front  of 
the  dorsal  spines,  following  profile  of  the  back  and  then  sinking  to  the  median  line  of  the 
body.    First  dorsal  spine  in  front  of  vertical  from  insertion  of  ventral. 

The  snout  is  compressed,  pointed,  much  produced  beyond  the  moderate  mouth.  The  cleft 
extends  nearly  to  the  vertical  through  the  middle  of  eye.  The  length  of  the  snout  is  li 
times  the  diameter  of  the  eye.  The  width  of  the  interorbital  area  is  slightly  less  than  the 
diameter  of  the  eye.  The  projection  of  the  snout  beyond  the  mouth  is  equal  to  the  diameter 
of  the  eye  or  nearly  so.  The  snout  is  compressed,  not  swollen.  Mouth  narrow,  transverse, 
its  width  about  one  fourth  the  length  of  the  head.  The  eye  is  placed  some  distance  below 
the  upper  profile  and  in  the  line  of  the  lateral  line  continued  to  the  nostrils.  Gill  opening 
wide;  the  membranes  confluent  and  slightly  in  advance  of  the  vertical  from  the  upper  end 
of  the  gill  opening;  not  attached  to  the  isthmus.     Scales  very  minute,  imbricated,  adherent. 

All  the  dorsal  spines  are  short,  the  anterior  very  short;  the  second  and  first  nearly  over 
the  origin  of  the  ventrals,  the  fifth  above  the  vent  and  the  sixth  slightly  behind  the  ori 
gin  of  the  anal.  The  longest  aboutone  half  as  long  as  the  eye.  The  last  (eleventh),  which  is 
followed  by  a  single  ray  attached  to  it  by  membrane,  is  over  the  fifteenth  spine  of  the  anal. 
The  dorsal  spines  are  distant  from  each  other,  and  behind  each  is  a  narrow  angular  mem- 
brane.   The  anal  begins  immediately  behind  the  vent,  and  in  its  middle  portion  is  consid-

erably  elevated;  the  length  of  its  longest  rays  is  about  equal  to  that  of  the  snout,  from 
which  point  it  slopes  rapidly  to  the  tip  of  the  tail.  The  pectoral,  placed  high  up  in  the 
middle  axis  of  the  body,  is  inserted  at  some  distance  behind  the  gill  openings,  and  is  broad 
and  nearly  oval  in  shape.  Ventrals  confluent,  some  distance  in  advance  of  the  vent,  stout, 
broad,  ovate  in  form,  not  extending  to  the  vent,  but  separated  from  it  by  a  distance  equal 
to  half  their  own  length.     Color,  uniform  light  brown.

A  Notamnthnx,  with  body  slender,  comparatively  elongate,  little  higher  over  ventrals 
than  over  pectorals ;  with  its  lateral  line  inconspicuous,  nearer  to  the  dorsal  than  to  the

ventral  outline,  not  arched  anteriorly.  Snout  produced  and  compressed.  Palatine  teeth 
in  a  single  series.  Ventrals  joined  by  a  membrane  of  considerable  width  between  the 
internal  rays.  The  height  of  the  body  is  about  one-thirteenth  of  its  length ;  its  thickness 
about  one-twentieth.  The  tail  does  not  appear  to  be  in  the  least  truncated,  though  so 
described  by  certain  authors,  one  of  whom  in  his  figure  shows  a  tail  carried  to  an  acute 
point,  making  the  length  of  the  body  considerably  greater  in  proportion  to  its  height  than 
is  indicated  in  his  own  description.  Color,  yellowish,  with  silvery  reflections;  the  limb  of 
the  operculum,  the  margin  of  the  orbit,  and  the  mouth  darker. 

Radial  formula:  D.  vi-vn;  A.  XII-100+;  Y.  ii,  ni-6  (iv-8 according  to  De  FUippiand 
Verany). 

This  form  was  carefully  figured  and  described  by  Risso  in  1840.  He  had  a  single  speci- 
men, 148  millimeters  long,  which  he  recognized  as  an  inhabitant  of  abyssal  depths  (Sejour 
abi/mes  marines  vaseux).  By  some  error,  his  description  and  figure,  otherwise  perfectly  con- 
sistent, disagreed  in  respect  to  the  number  of  spines  in  the  dorsal  fin,  the  figure  showing 
seven,  the  description  nine.  Misled  by  this.  De  Filippi  and  Verany  redescribed  the  same  fish 
in  1859,  and  to  justify  their  course  proposed  the  theory  that  Risso's  description  and  figure 


DISCUSSION   OP    SPECIES    AND    THEIR    DISTRIBUTION.  167 

wore  based  on  different  specimens,  a  theory  accepted  without  criticism  by  later  writers,  but 

which  we  can  not  believe  a  true  one. 

Kisso  was  a  careful  and  experienced  worker,  and  it  would  be  unjust  to  the  memory  of 
one  of  the  best  Italian  ichthyologists  to  admit  that  he  could  be  guilty  of  such  an  error. 
Then,  too,  he  states  positively  that  he  had  only  a  single  specimen.  It  is  much  more  prob- 
able that  the  German  typesetter,  in  the  office  of  Wiegmann's  Archiv,  mistook  a  "  7"  for  a 
"9"  in  Risso's  manuscript. 

Bisso's  figure  is  a  good  one  of  a  young  N~.  mediterraneus,  and  his  description  agrees 
with  it  perfectly  with  the  exception  of  this  one  figure  in  the  text. 

The  specimen  described  and  figured  by  G-iinther  under  the  name  X.  mediterraneus  is 
not  a  Mediterranean  form,  but  one  from  the  southern  Pacific,  and  has  been  referred  by  us 
to  a  new  genus  and  species.  Moreau  is  in  error  in  referring  the  figures  of  Bloch  and  of 
Cuvier  and  Valenciennes  to  this  species  (see  discussion  under  NotacantUus  nasus). 

X.  Bonapartii  was  describedunder  the  name  X.  mediterraneus,  by  DeFilippi  and  Verany 
in  1857  from  a  specimen  obtained  at  Nice,  and  preserved  in  the  Zoological  Museum  at  Turin. 
Two  others  from  the  same  locality,  referred  by  Moreau  to  this  species,  are  in  the  Museum 
in  Paris.  The  Travailleur  and  Talisman  obtained  four  additional  individuals:  one  from 
the  coast  of  Soudan,  at  a  depth  of  1,232 meters,  and  another  from  the  same  region  at  932 
meters;  two  from  the  Banc  D'Arguin  at  1,495  meters.  These  last  have  been  made  the  sub- 
ject of  an  elaborate  description  by  Vaillant,  who  also  publishes  a  good  figure. 

This  species  is  distinguished  from  X.  sexspinis  (Fig.  192  A,  B),  described  by  Richard- 
son from  Australian  seas  (Voyage  Erebus  and  Terror,  Fishes,  54,  pl.xxxn,  Figs.  4-11),  and 
subsequently  described  by  Gunther,  who  also  gives  an  excellent  figure  (Challenger  Report 
xxn,  243,  id.  lxi,  Fig.  a),  by  various  characters,  most  striking  of  which  is  the  difference 
in  the  relationships  of  the  position  of  the  dorsal  spines  and  the  soft  anal  fin.  In  X.  sex- 
sjiinis  the  dorsal  and  soft  anal  do  not  pass  the  same  vertical,  whereas  in  JV.  mediterraneus 
the  last  three  dorsal  spines  are  placed  over  the  anterior  part  of  the  soft   anal. 

The  type  of  X.  mediterraneus  from  Nice  was  examined  by  Giglioli  at  the  Turin  Museum 
in  1882.  Its  total  length  is  203  millimeters,  and  its  radial  formula  D.  G/l;  A.  12/132?:  V. 
3-4/8;  C.  .->.'. 

Prof.   Giglioli   informs  us  that  in  his  "Central  Collection    of   Italian  Vertebrata"  at 
Florence  he  has  four  specimens  of  X.  Bonapartii,  as  follows: 

a.  Nice,  August  11,  1882.    Total  length  153  millimeters.     D.  8/1;  A.  6-7/120;  V.  3/6-7;  p.  9-10;  C.  3-4?.    A 

large,  curved  spine  in  upper  corner  of  mouth  on  either  side. 

b.  Nice,  March  7,1891.     Total  length  205   millimeters.      D.  7/1;  A.  14-120;  V.  3  7;  P.  12;  C.  4?.      Buccal 

spines  hidden  in  skin. 

c.  Nice,  June  15, 1892.     Total  length  203  millimeters.     D.  7/1;  A.  8?/140;  V.  3/5-7;  P.  10-12.     Buccal  spines 

large  and  prominent. 

d.  Syracuse,  1855-60?.    D.  7/1;  A.  11/25;  P.  9-10;  V.  3/5. 

Another  specimen,  collected  by  Bellotti  at  Messina,  December  12, 1S82,  and  now  in  the 
Museo  Civico  at  Milan,  was  examined  by  Giglioli,  who  states  that  it  was  104  millimeters 
long,  and  had  D.  7/1;  A.  7/?;  V.  3/6;  P.  10-12;  C.  51.

A  Xotarantlnis.  with  its  body  a  little  higher  over  the  veutrals  than  over  pectorals,  and 
comparatively  elongated;  with  its  lateral  line  slightly  arched  above  the  pectorals,  sinking

the  diameter  of  one  of  the  dorsal  spines)  but  upon  the  anterior  half  of  the  body  about  three 
times  as  large,  decreasing  in  size  upon  posterior  half,  until  upon  tail  they  are  smaller  than

covered  in  every  part,  even  the  lips,  with  small  scales,  of  which  there  are  about  40  betweeu 
eye  and  end  of  opercular  flap.  Scales  deeply  imbedded  (iu  life  probably  hidden  beneath 
a  slimy  epidermis). 

Length  of  the  head  about  74,  times  in  that  of  body.  The  bones  are  flexible,  and  their  out- 
lines are  invisible  without  dissection,  the  whole  being  covered  with  a  leathery  skin.  Width 
of  interorbital  space  appeals  to  be  (in  the  mutilated  head)  somewhat  greater  than  length  of 
snout,  and  about  one-fourth  length  of  the  head.  Diameter  of  orbit  appears  to  be  about 
one-half  width  of  interorbital  space.  Length  of  postorbital  portion  of  head  nearly  3  times 
that  of  snout.  Length  of  mandibular  bone  slightly  exceeds  twice  diameter  of  eye;  that 
of  upper  jaw  considerably  greater.  Teeth  in  upper  jaw  blunt,  accicular,  set  side  by  side 
like  the  teeth  of  a  comb,  about  32  on  each  side.  In  lower  jaw  shorter,  slenderer,  and  in 
double  rows.    Yilliform  teeth  upon  palatines. 

Dorsal  fin  begins  at  a  distance  from  snout  not  far  from  2%  times  length  of  the  head, 
and  nearly  over  the  one  hundred  and  tenth  scale  of  lateral  line;  it  consists  of  10  low,  widely 
separated  spines,  unconnected  by  any  membrane.  Distance  between  first  and  tenth  spine 
nearly  double  length  of  head. 

Spines  from  fourth  to  ninth  about  equidistant,  while  other  interspaces  are  shorter. 

Distance  from  snout  to  anal  fin  equal  to  about  four  times  length  of  head.  Anterior 
spinous  portion  of  anal  resembles  dorsal  and  is  devoid  of  connecting  membrane.  (The 
membrane  is  also  absent  from  the  posterior  half  of  the  fin,  but  may  possibly  have  been 
destroyed.  Anal  rays  extend  to  tip  of  tail  and  number  about  130,  the  number  of  spines 
being  19.  Anal  begins  immediately  behind  vent,  and  its  length  of  base  is  slightly  less  than 
half  that  of  body  (less  by  a  length  about  equal  to  the  distance  from  the  angle  of  the  mouth 
to  the  gill-opening). 

Pectoral  fin  placed  at  a  distance  behind  the  gill-opening  about  equal  to  width  of  its 
own  base.  (Its  length  is  at  least  double  this  distance — how  much,  more  can  not  be  deter- 
mined, but  the  fin  is  evidently  short  and  rounded  in  contour,  the  upper  rays  longest).  Its 
base  is  stout,  peduncular,  and  thickly  covered  with  scales. 

Distance  of  the  ventrals  from  snout  equal  to  that  of  the  dorsal,  though  its  insertion  is 
slightly  in  advance  of  that  of  dorsal.  Ventrals  closely  adjacent,  separated  by  narrow 
groove,  broad,  with  peduncle-like  bases,  thickly  covered  with  scales  and  provided  witt 
two  spines  and  eight  or  nine  rays  (as  nearly  as  the  specimen  will  permit  determination).

DISCUSSION    OF    SPECIES    AND    THEIR    DISTRIBUTION.  169 

The  U.  S.  Fish  Commission  received  the  type  from  the  schooner  Gatherer,  of  Glouces- 
ter, ('apt.  Briggs  Gilpatrick,  which  had  been  taken  from  the  stomach  of  a  Ground-shark, 
[Somniosus  brevipinnis),  on  the  Grand  Bank  of  Newfoundland. 

GIGLIOLIA,  Goode  and  Bean,  n.  g. 

A  genus  of  Notaeanthidce,  distinguished  from  Hfotacanthus  by  the  less  advanced  position 

of  the  dorsal,  the  first  dorsal  spine  being  placed  in  the  vertical  over  the  vent  and  (dose  to 
the  vertical  from  the  first  anal  spine.  Dorsal  spines  6-9;  anal  spines  1,1-18,  these  being 
longer  and  more  slender  than  in  Nbtacanthtis,  enveloped  nearly  to  their  tips  in  a  membrane, 
and  grading  imperceptibly  in  length  and  size  into  those  of  the  anal,  which  is  co?  paratively 
high.  The  greatest  height  of  the  body  is  in  the  region  of  the  ventral  tins,  am  .he  lateral 
line,  which  is  conspicuous,  is  arched  over  the  pectorals  and  ventrals,  but  follows  closely  the 
dorsal  outline  until  it  passes  beyond  the  dorsal  spines,  alter  which  it  is  directed  in  a  straight 
line  to  the  tip  of  the  pointed  tail.  Head  comparatively  broad,  mouth  interior,  almost  suc- 
torial, with  lip  absent  in  the  middle  portion  of  mouth  in  front;  teeth  in  each  intermaxillary 
20-22;  snout  thick,  swollen,  much  produced,  nostrils  large,  conspicuous,  covered  by  a  mem- 
branous tlap.  Pectoral  short,  broad,  rounded.  Ventrals  placed  low  down  and  completely 
united,  extending  to  the  vent. 

In  general  appearance  and  proportions  this  form  resembles  the  high-backed  division  of 
the  genus  Notacanihus,  to  which  belong  V.  nanus  and  N.  Chemnitzii.  Its  mouth,  however, 
is  placed  more  on  the  under  surface  of  the  head  than  even  in  N.  sexspinis. 

This  genus  is  named  in  honor  of  Commendatore  Enrico  Ilillyer  Giglioli,  professor  in  the 
University  of  Florence,  and  founder  of  the  Central  Museum  of  Italian  Vertebrates,  who  has 
been  a  leader  in  all  the  efforts  of  the  Italian  Government  in  deep-sea  research,  and  whose 
thorough  works  upon  the  geographical  distribution  of  Italian  vertebrates,  both  terrestrial 
and  aquatic,  are  of  an  importance  which  can  not  be  overvalued. 

The  only  species  assigned  to  this  genus  is  that  obtained  by  the  Challenger  off  the  south- 
west coast  of  South  America,  and  referred  by  Giintherto  Wotacanthus  Bonapartii.  This 
form,  represented  by  a  single  individual  Hi  inches  long,  from  a  depth  of  400  fathoms  at 
station  310,  we  propose  to  designate  by  the  specific  name  Moseleyi,  in  memory  of  the  late 
lamented  Henry  Xottidge  Moseley,  f.  r.  s.,  who  was  naturalist  of  the  Challenger,  and  Liuacre 
professor  in  the  University  of  Oxford.

The  following  excellent  description  is  that  written  by  Dr.  Giiuther: 

Body  moderately  elongate,  its  greatest  depth  opposite  the  ventral  fin  and  contained 
2§  times  in  distance  of  the  vent  from  the  end  of  the  snout;  the  length  of  the  compressed 
oblong  head  is  contained  2£  times  in  the  same  length.  The  snout  is  thick,  swollen,  much 
produced  beyond  the  narrow  transverse  mouth,  which  is  opposite  to  the  front  margin  of 
the  orbit,  and  quite  at  the  lower  side  of  the  head.  Twenty  teeth  on  each  side  of  the  upper 
jaw.  The  eye  is  close  to  the  upper  profile,  two-thirds  of  the  length  of  the  snout,  one-fifth  of 
that  of  the  head,  and  less  than  the  width  of  the  interorbital  space.  Gill-openings  of  mod- 
erate width,  the  gill-membranes  being  confluent  in  the  vertical  from  the  upper  end  of  the 
gill-opening,  and  not  attached  to  the  isthmus. 

The  whole  body  and  head  are  covered  with  minute,  smooth,  imbricate,  and  adherent 
scales. 

All  the  dorsal  spines  are  short,  the  anterior  very  short,  the  second  opposite  to  the  vent. 
The  anal  spines  commence  immediately  behind  the  vent,  and  increase  in  length  posteriorly. 
passing  into  the  flexible  rays,  which  are  of  varying  and  indefinite  number.  The  pectoral  is 
inserted  at  the  usual  distance  from  the  gill-opening,  and  has  a  base  of  moderate  width. 
Ventrals  united  and  extending  to  the  vent.

Notacanthids,  with  very  slender,  elongate  body,  and  inferior  mouth,  and  the  snout  pro- 
longed into  a  proboscis-like  tip,  resembling  that  of  Mastacembelus;  its  length  at  least  one- 
third  that  of  the  head.  Dorsal  fin  represented  by  numerous  slender,  curved,  flexible,  dis- 
joined spines,  the  first  of  which  is  placed  some  distance  behind  the  vertical  from  the  origin 
of  the  pectoral.  Anal  composed  of  a  smaller  number  of  longer,  slender,  flexible  spines, 
passing  at  a  point  some  distance  behind  the  last  of  the  dorsal  spines  into  a  low,  short,  anal 
fin.  Pectorals  moderate,  slender,  placed  above  the  median  line  of  the  body,  and  close  to  the 
lateral  line.  Ventrals  slender,  entirely  separate,  not  reaching  to  the  vent.  Scales  incon- 
spicuous or  probably  absent.  Lateral  line  conspicuous,  descending  from  the  angle  of  the 
operculum  in  a  strong,  broad  curve  to  below  the  middle  region  of  the  body  at  a  point  not 
far  from  the  vent.  Teeth  very  fine,  in  rows  upon  each  jaw :  stronger  teeth  upon  the  palate,

body.  Snout  very  elongate,  oue-third  of  the  length  of  the  head;  as  long  as  the  height  of 
the  body  at  the  shoulders,  and  three  times  the  diameter  of  the  eye.  In  form  resembling 
that  (if  Mastacembelus.  "The  condition  of  the  type,"  remarks  Vaillant,  "does  not  allow  us 
to  estimate  the  size  of  the  mouth,  but  its  commissure  does  not  reach  tbe  anterior  edge  of  the 
orbit.  Its  form  is  analogous  to  that  in  other  species  of  the  genus,  that  is  to  say,  its  inferior 
teeth  are  exceedingly  fine  and  closely  set,  in  the  jaws,  while  there  are  stronger  teeth  upon 
the  palate,  where  they  are  arranged  in  the  form  of  a  horseshoe." 

Eye  moderate  in  size,  its  diameter  one-eighth  the  length  of  the  head;  interorbital  space 
very  narrow,  not  one-half  the  diameter  of  the  eye.  Branchial  opening  large.  Operculum 
truncated  posteriorly. 

Vent  in  front  of  the  middle  of  the  body. 

No  traces  of  scales.  The  lateral  line,  however,  is  conspicuous,  and  it  descends  from  the 
upper  angle  of  tbe  operculum  to  the  middle  of  the  body,  or  a  little  below  it,  in  the  vicinity 
of  the  region  of  the  vent.  The  first  dorsal  spine  is  placed  two  thirds  times  its  own  length 
back  of  the  vertical  from  the  axil  of  the  pectoral,  and  its  length  is  less  than  the  diameter  of 
the  eye.  The  highest  dorsal  spines,  those  in  the  posterior  third  of  the  fin,  are  twice  as  long 
as  the  diameter  of  the  eye.    The  spines  are  all  slightly  curved  backward,  and  there  is  a  soft,

separate  caudal  fin,  but  it  is  by  no  means  certain  that  this  exists.  The  pectoral  is  placed 
a  considerable  distance  from  the  operculum,  nearly  equal  to  the  length  of  the  snout,  and 
its  lower  axil  is  in  the  median  line  of  the  body,  or  nearly  so.  Its  length  is  about  equal 
to  1  hat  of  the  snout.  The  vent  rals,  situated  at  a  distance  from  the  snout  equal  to  about 
one-third  of  the  length  of  the  body,  do  not  reach  the  anus,  and  are  the  same  size  as  the 
pectorals.  In  Vaillant's  specimen  they  appear  to  be  separate,  and  he  was  able  to  observe 
but  a  single  spine.     The  color,  in  fresh  condition,  was  milky  white;  the  head  and  iris  black. 

Radial  formula,  D.  29-37;  A.  34-41. 

This  species  was  known  to  Risso,  who  had  in  his  collection  the  specimen  which  after- 
wards served  De  Filippi  as  a  type  and  which  is  now  in  the  Turin  Museum.  A  sketch  by 
Eisso,  of  this  fish,  is  here  reproduced.  The  Turin  specimen  was  examined  by  Prof.  Giglioli 
in  1882:  it  is  160  millimeters  long  and  has  the  following  radial  formula:  D.  29/1;  A.  35. 

Prof.  Giglioli  has  three  specimens  in  his  collection  at  Florence.  We  are  indebted  to 
him  for  the  following  details  concerning  them: 

a.  Nice,  August  5,  1881  (typo  of  Paradoxichthya  Qaribaldianw) :  Total  length,  199  millimeters.     D.  32/0;  A. 
38/100;  P.  9-10;  V.  1-10;  C.  4?.     This  specimen  has  a  long,  straight  spine,  pointed  backwards,  above  the 
maxillary  bone  on  either  side. 
6.  Nice.  March  1,  1891:  Total  length,  186  millimeters.    D.  30  1;  A.  41/150;  P.  10;  V.  1/10C.4?.   Found  dead 

and  partly  decomposed.     The  peculiar  maxillary  spine  is  small  in  this  and  in  the  following  specimen,

Notacanthids,  with  elongate  body  and  inferior  mouth.  Body  and  head  covered  with 
minute,  imbricated  scales.  Dorsal  fin  represented  by  numerous  short,  straight,  robust  and 
disjoined  spines,  27  to  34  in  number,  the  first  in  advance  of  the  insertion  of  the  pectoral. 
Anal  as  in  Wotaccmthus,  but  lower,  and  with  a  longer  portion  of  low,  short,  slightly  curved, 
disjoined  spines,  from  35  to  55  in  number,  which  under  the  final  dorsal  spines  pass  into  flexi- 
ble rays.  Lateral  line  straight,  conspicuous.  Pectorals  moderate,  placed  far  back,  below 
the  middle  line  of  the  body,  and  remote  from  the  lateral  line.  Teeth  in  jaws  erect,  small; 
and  also  in  series  on  the  vomer  and  palate.  A  line  of  pores  on  the  inner  edge  of  the  mandi- 
ble.    Ventrals  moderate,  entirely  separate. 

This  genus  is  named  in  honor  of  Col.  Marshall  MacDonald,  U.  S.  Commissioner  of 
Fisheries,  in  commemoration  of  his  liberal  policy  in  furthering  ichthyological  research.

The  body  is  greatly  compressed,  its  outlines  tapering  rapidly  in  both  directions  from 
the  origin  of  the  vent.  Its  greatest  height  is  contained  3i  times  in  the  distance  of  the  vent 
from  the  tip  of  the  snout,  or  about  four  fifths  the  length  of  the  head,  which  is  contained  94 
times  in  the  total.  The  snout  is  compressed,  pointed,  snake  like,  produced  beyond  the  mouth 
a  distance  less  than  the  diameter  of  the  eye  and  contained  3  times  in  the  length  of  the 
head.  The  mouth  is  small;  its  cleft  scarcely  reaches  to  the  anterior  nostril.  Each  jaw  is 
armed  with  a  series  of  minute  teeth  and  a  similar  series  on  vomer  and  palate.  The  eye  is 
moderate  in  size,  placed  not  far  from  the  dorsal  profile,  distant  about  2 4  diameters  from 
the  end  of  the  snout,  more  than  3  diameters  from  the  end  of  the  onercle.    Gill  opening  wide. 


]  72  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

The  body  and  head  covered  by  minute,  imbricated  scales.  A  line  of  mucous  pores  extends 
from  the  anterior  end  of  the  lateral  line  forward  under  the  eye  and  to  the  end  of  the  maxilla. 

The  dorsal  spines  are  short,  distant  from  one  another,  the  first  being  over  the  end  of 
the  opercle,  the  fifth  slightly  behind  the  vertical  through  the  origin  of  the  pectoral,  the 
twelfth  slightly  in  advance  of  theorigin  of  the  pectoral,  the  fifteenth  almost  over  the  origin 
of  the  anal,  and  the  last  (twenty-eighth)  a  little  behind  the  middle  of  the  length  of  the  tail. 
In  another  individual  the  fourth  spine  is  immediately  over  the  pectoral  insertion,  the  thir- 
teenth over  the  ventral  origin,  and  the  whole  number  of  spines  is  30,  but  there  is  behind 
the  thirtieth  a  minute  spine  almost  united  by  membrane.  The  anal  begins  immediately 
behind  the  vent  and  after  the  fifth  spine  the  height  of  the  fin  remains  uniform  until  the 
length  of  the  rays  gradually  decreases  near  the  tip  of  the  tail.  The  pectoral  is  inserted  at 
a  distance  from  the  gill  opening  nearly  twice  its  own  length.  The  ventrals  have  a  broad 
base,  are  not  confluent,  and  reach  to  the  vent  or  slightly  beyond  it.

The  types  are  number  35601,  U.  S.  N.  M. ,  and  were  obtained  by  the  steamer  Albatross 
at  station  2216,  K  lat.  39°  47',  W.  Ion.  70°  30'  30",  in  a  depth  of  963  fathoms.  They  meas-

named by  Vaillant  in  the  report  of  the  Travailleur  and  Talisman,  p.  387.  This  is  distin- 
guished by  the  larger  number  of  its  dorsal  rays,  the  less  anterior  position  of  the  origin  of 
the  dorsal,  the  lesser  height  of  the  body  in  comparison  with  the  distance  from  the  vent  to 
the  snout,  comparatively  longer  snout  and  larger  eye,  and  the  absence  of  the  suborbital  row 
of  mucous  pores. 

This  form  was  obtained  by  the  Challenger  at  station  237,  south  of  Yeddo,  in  1,875 
fathoms. 

Dr.  Giinther  states  that  although  this  is  a  matter  of  some  uncertainty,  the  diagnosis  of 
H.  Rissoanus  '-applies  sufficiently  well  to  his  specimen;"  further  remarking  that ''since  a 
number  of  Mediterranean  fishes  are  identical  with  Japanese,  and  at  least  one  other  species 
of  Notacanthus  (A.  Bonapartii)  shows  a  wide  geographical  range,  he  should  not  feel  justi- 
fied in  giving  a  distinct  name  to  the  fish  described."  We  can  not  help  feeling  that  Dr. 
(iiiuther  has  departed  from  his  customary  cautious  and  scientific  method  in  this  case,  and 
are  satisfied  that  he  would  not  have  done  so  had  he  seen  the  specimen  obtained  by  the 
French  exploring  expedition  on  the  coast  of  Morocco,  and  described  and  figured  by  Vail- 
lant. Coming,  as  it  does,  from  the  Mediterranean  region,  and  having  the  proboscis-like 
character  of  the  snout,  much  more  emphasized  than  in  the  Japanese  form,  the  presumptions 
in  favor  of  its  identity  with  A.  Rissoanus  are  very  strong.  We  therefore  not  only  adopt  the 
identification  of  Vaillant  in  preference  to  that  of  Giinther,  but  accept  the  new  name  which 
Vaillant  has  proposed  for  the  Japanese  form. 

Family  LIPOGENYID^. 
IApogenyidce,  Gill,  MS. 

Heteromes  with  a  roundish,  inferior,  suctorial  mouth ;  imperfect  lower  jaw  with  its  rami 
separated  at  middle,  connected  with  the  corresponding  sides  of  the  upper  jaw,  and  invested 
in  a  thick,  transversely  plicated,  horseshoe  shaped  lip,  reflected  upwards  behind  on  the 
cheeks;  no  teeth;  short  row  of  4  or  5  partially  connected  graduated  dorsal  spines  and  5  to 
7  branched  rays,  forming  a  regular  fin.     (Gill.) 

The  anomalous  and  unexampled  modification  of  the  lower  jaw  and  mouth  deserves  a  de- 
tailed anatomical  examination,  but  the  existence  of  only  one  specimen — for  the  present,  at 
least; — is  deemed  to  render  such  an  investigation  inadvisable. 


DISCUSSION   OF    SPECIES   AND   THEIR    DISTRIBUTION.  173 

LIPOGENYS,  Goode  and  Bean,  n.  g. 

Head  and  body  compressed,  the  body  elongate,  as  in  Wotacanfhus.  Snout  produced, 
compressed,  obtuse  al  tip.  Cleft  of  the  mouth  inferior,  suctorial,  circular  in  bout,  sur- 
rounded by  rugose,  contractile  lip.  with  cleft  posteriorly,  flanked  by  wing-like  flaps,  con 
taining  the  modified  mandibular^  boms,  which  articulate  with  the  end  of  the  maxilla,  and 
are  free  behind.  A  concealed  spine  at  the  endof  the  maxilla.  No  teeth.  Anterior  nostril 
in  short  tube,  the  posterior  oblong,  under  a  short  flap.  Dorsal  tin  short,  but  normal  ami 
well  developed,  with  a  distinct  soft  portion.  Anal  tin  norma]  in  position,  high,  with  many 
Spines,  and  with  some  of  the  rays  spine  like,  though  forked.  A  distinct,  though  very  small, 
caudal  tin.  Ventrals  normal,  well  developed,  with  several  spines.  Scales  minute,  very 
numerous.     Lateral  line  conspicuous  anteriorly. 

LIPOGENYS  GILLII,  Goodk  and  Bean,  n.  s.  (Figures  190;  196  A,  B.) 

Body  compressed,  its  greatest  width  one-half  its  height,  which  is  about  one-tenth  of  the 
length.  The  length  of  the  head  is  contained  Sjf  times  in  that  of  the  body  and  twice  in  the 
distance  from  the  origin  of  the  pectoral  to  the  vent.  The  width  of  the  interorbital  space 
is  about  equal  to  the  diameter  of  the  eye,  which  is  one-fifth  the  length  of  the  head.  The 
length  of  the  snout  is  nearly  one-fourth  that  of  the  head.  The  postorbital  portion  of  the 
head  is  twice  as  long  as  the  snout.  The  peculiar  form  of  the  jaws  and  mouth  has  been  de- 
scribed under  the  head  of  the  genus.  The  diameter  of  the  circular  opening  is  about  one- 
half  the  diameter  of  the  eye.  The  dorsal  fin  begins  at  a  distance  from  the  snout  equal  to 
about  three  times  the  length  of  the  head.  It  consists  of  5  graduated  spines,  of  which  the 
first  is  minute  and  the  longest  as  long  as  the  snout,  and  5  rays,  of  which  the  second  is 
longest,  nearly  one-half  as  long  as  the  head.  The  spines  and  rays  are  all  compactly 
arranged  in  a  strong,  triangular  tin.  The  length  of  the  dorsal  base  equals  one  half  that  of 
the  head.  The  anal  begins  under  the  fourth  spine  of  the  dorsal;  it  contains  -11  spines  and 
SS  rays,  of  which  the  anterior  ten  are  stiff,  though  articulated,  and  divided  at  the  tip.  The 
longest  ray  is  longer  than  the  longest  spine,  about  as  long  as  the  snout.  The  ventral  con- 
sists of  3  spines  and  7  rays.  The  two  fins  almost  meet  in  the  median  line,  but  are  discon- 
nected. The  fin  readies  to  the  vent.  Its  distance  from  the  tip  of  the  snout  is  about  2J 
times  the  length  of  the  head.  The  pectoral  is  placed  below  the  median  line  of  the  body,  at 
a  distance  from  the  head  about  equal  to  the  diameter  of  the  eye;  its  length  is  a  little  greater 
than  the  postorbital  part  of  the  head.  The  lateral  line  is  well  developed  anteriorly,  becom- 
ing obsolete  at  a  distance  from  the  end  of  the  dorsal  about  equal  to  l!i  times  the  length  of 
the  head. 

The  color  is  uniform  light  brown.  The  under  sideof  the  gill  covers  dark,  showing  dark 
at  the  edges  of  the  opercular  bone. 

The  type  measures  17  inches  in  length.  It  is  No.  39212,  and  was  taken  by  the  steamer 
Albatross  at  statiou  2742,  in  K  lat.  37°  46'  30",  W.  long.  73°  56'  30",  from  a  depth  of  865 
fathoms. 

Order    TELEOCEPHALI. 

Teleocephiili,  Gux,  Johnson's  Cyclopaedia,  iv,  763,  1S77. 

Skeleton  more  or  less  ossified;  skull  well  developed,  and  its  elements  numerous,  with 
cranial  bones  as  follows:  Of  cartilage  bones,  basioccipital,  exoccipital,  supraoccipital,  basi-

by  postero-teinporal  and  post-temporal  bones;  the  brain  is  differentiated,  according  to  the 
current  nomenclature,  into  (1)  a  cerebral  part,  consisting  of  cerebral  hemispheres  and  optic 
lobes,  and,  in  front,  small,  olfactory  lobes;  and  (12)  a  cerebellar  part,  cerebellum,  which  is 
moderately  developed,  covered,  and  simple.     {Gill.)

Body  oblong  or  ovate,  compressed,  with  scales  ctenoid,  cycloid,  foliate,  or  granular. 
Head  large  and  thick,  not  exceedingly  cavernous.  Mouth  wide,  oblique.  Eye  lateral  and 
large.  Maxillaries  large,  premaxillaries  protractile;  suborbitals  narrow.  Teeth  villiform, 
in  one  or  more  bands,  sometimes  with  a  few  pairs  of  fangs,  as  in  Caulolepis.  Opercular 
bones  usually  spinous,  and  the  other  bones  of  the  head  usually  strongly  serrated.  Branch- 
iostegals  vii- vin ;  gill  membranes  separate,  3;  gills  4,  a  slit  behind  the  fourth;  pseudo- 
branchiae  present;  gill-rakers  moderate.  A  single  dorsal;  anal  with  but  few  spinous  rays; 
ventral  fins  thoracic,  with  (>  or  more  soft  rays;  pyloric  caeca  numerous. 

This  family  is  characteristically  bathybial,  few  members  being  known  to  occur  in  shal- 
low waters,  and,  indeed,  with  the  exception  of  the  family  Holocentridce,  the  whole  of  the 
superfamily  Berycoidea  as  proposed  by  Gill,  including  the  families  /.'(///'"'"'(except  two 
species  of  Beryx),  Trachichthyidce,  Stqphanoberycidce,  and  Anomalopidw,  are  found  at  very 
considerable  depths.  Monoeentridce,  known  from  Chinese  and  Japanese  seas,  are  probably 
also  inhabitants  of  the  region  below  100  fathoms.  As  Giinther  has  shown,  this  group  are 
found  only  in  the  sea,  and  are  provided  with  highly  developed  apparatus  for  the  secre- 
tion of  superficial  mucus,  thus  fitting  them  for  living  at  a  greater  depth  than  any  other 
allied  group.  "They  have,''  wrote  Giinther,  "a  world-wide  distribution  in  all  tropical  seas." 
In  this  connection  the  geological  history  of  this  group  is  particularly  significant.  "  Fossil 
Berycoids,"  says  Giinther,  "show  a  still  greater  diversity  of  form  than  living;  they  belong 
to  the  oldest  Teleosteous  fishes,  the  majority  of  Acanthopterygians  found  in  the  chalk  being 
representatives  of  this  family.  Beryx  lias  been  found  in  several  species,  with  other  genera 
now  extinct:  Pseudoberyx,  with  abdominal  ventrals,  from  Mount  Lebanon;  Berycopsis,  with 
cycloid  scales;  Ilomonnti/s,  stcnustontu,  Sphenvaplndus,  Acanus,  Soplopteryx,  Platycormtw, 
with  granular  scales;  Podocys,  with  a  dorsal  fin  extending  to  the  neck:  Acrogaster,  Macro- 
lepis,  and  Bhacolepis,  from  the  chalk  of  Brazil.  Species  of  Holocentrum  and  Myripristis 
occur  in  the  Monte  Bolca  formation."

Body  oblong,  compressed;  abdomen  trenchant,  not  carinated.  Scales  ctenoid,  ar-

Body  oblong,  considerably  compressed,  its  height  greatest  at  the  origin  of  the  dor- 
sal; contained  2£  times  in  its  length,  and  equal  to  the  length  of  the  head.  The  upper 
maxillary  bone  reaches  almost  to  the  middle  of  the  orbit.  The  eye  is  very  large,  its  diam- 
eter about  21  times  in  the  distance  from  the  tip  of  the  snout  to  the  extremity  of  the 
operculum,  its  upper  limb  impinging  upon  the  upper  profile  of  the  head.  The  distance  of 
the  insertion  of  the  pectoral  from  the  snout  is  equal  to  the  length  of  the  base  of  the  anal. 
The  insertion  of  the  anal  is  approximately  in  the  vertical  from  the  tenth  to  the  twelfth 
dorsal  ray,  and  its  middle  is  slightly  behind  the  ultimate  ray  of  the  dorsal.  The  ventral  is 
inserted  under  the  axil  of  the  pectoral.  The  scales  are  sharply  ctenoid,  with  a  strong  middle 
keel;  the  number  in  the  lateral  line  is  64  to  65,  and  there  are  said  to  be  from  34  to  35  in 
the  transverse  row,  although  the  published  figures  indicate  about  18  below  the  lateral  line, 
and  pet  Imps  half  the  number  above. 

Radial  formula:     D.  IV,  16-19;  A.  IV,  28-29;  V.  1-10;  P.  14  (t). 

This  species  was  first  described  by  Cuvier  from  a  dried  specimen  in  the  Museum  at 
Lisbon,  which  at  the  time  was  supposed  to  have  come  from  Madeira,  but  which  is  more  likely 
to  have  been  from  the  coast  of  Portugal,  since  Capello  finds  it  not  infrequent  in  the  markets

of  Lisbon  from  January  to  April,  where  it  i.s  known  as  the  Im/perador.  It  was  afterwards 
found  at  Madeira  by  Lowe.  who.  unaware  of  the  existence  of  two  species  in  those  waters, 
figured  it  in  the  Cambridge  Transactions  under  the  name  of  B.  splendens,  and  it  has  since 
been  found  to  be  almost  as  abundant  about  Madeira  as  Lowe's  subsequently  described 
species.  It  is  known  by  the  Madeiran  fishermen  as  the  Alfonsin  a  casta  larga,  and  it 
is  more  brilliantly  scarlet,  though  it  has  a  paler  mouth.  It  is  obtained  at  a  depth  of  from 
300  to  400  fathoms,  at  from  1  to  2  leagues  from  the  shore,  and  attains  the  weight  of  -I  or 

5  pounds.  The  Challenger  obtained  specimens  from  the  Sea  of  Japan  at  a  depth  of  345 
fathoms.     Dr.  Doderlein  also  obtained  specimens  in  Japan  in  1881. 

The  type  of  B.  borealis  was  taken  at  Borna^s,  near  Bergen,  March  S,  1839.  Two  addi- 
tional examples,  referred  to  this  species,  were  secured  near  Bergen  in  1871;  these  are  men- 
tioned in  "Norges  Fiske,"  1871,  and  again  by  Lilljeborg  in  his  " Skandinavisk  Fauna"  in 
1881.    Lilljeborg  admitted  it  as  a  species  doubtfully  distinct  from  B.  decadactylus. 

Collett  has  compared  the  type  of  B.  borealis  with  an  adult  specimen  of  B.  decadactylus 
from  Madeira  and  with  Steindachner's  descriptions  of  examples  of  this  species  from  Lisbon 
and  the  Canaries  and  those  taken  by  Doderlein  in  Japan.  The  type  of  B.  borealis  is  only 
280  millimeters  long,  and  Collett  is  satisfied  of  its  identity  with  B.  decadactylus.  He  has 
critically  studied  the  chief  diagnostic  characters  relied  upon  by  Diiben  and  Koren,  namely, 
the  greater  height  of  the  body  and  the  number  and  size  of  the  nasal  spines. 

We  present  below  a  translation  of  the  essential  parts  of  his  discussion: 

Lowe,  in  1840,  and  Steindachner,  in  1877,  showed  that  the  character  stated  by  Cuv. 

6  Val.  (copied  by  Giinther)  of  the  body  height  in  li.  decadactylus  equaling  the  length  of 
head,  is  erroneous.  In  this  species  the  length  of  the  head  is  always  less  than  height  of 
body,  and  is  contained  in  it  from  1±  to  14  times.  In  the  Museum  example  from  Madeira 
the  proportion  between  the  head  length  and  body  height  is  as  1  to  1.33;  in  the  type  of  />'.  bore- 
alis, winch  is  ouly  one-half  as  long  as  the  Madeira  specimen,  and  thus  should  have  a  rela- 
tively greater  height  of  body,  the  proportion  is  as  1  to  1.43.  No  specific  difference  can  be 
based  on  tins  character. 

The  number  and  size  of  the  spines  of  the  snout  he  found  to  vary  with  the  size  and  age 
of  the  fish,  and  he  concludes  that  this  character  is  unimportant.  In  Japanese  examples  of 
/.'.  decadactylus,  measuring  370  millimeters,  the  preorbital  spine  is  one-third  as  long  as  the 
eye,  almost  exactly  as  in  the  typical  specimen  of  B.  borealis.  The  relative  length  of  this 
spine  decreases  with  age. 

In  the  radial  formula  and  number  of  scales.  /;.  borealis  and  B.  decadactylus  agree. 
There  is  no  difference  in  their  proportions,  dentition,  and  other  specific  characters.

Body  compressed,  elongate,  its  height  equal  to  the  length  of  the  head,  and  contained 
3i  times  in  the  total.  The  pectoral  and  dorsal  fins,  which  are  equal  in  length,  are  one-fifth 
of  the  entire  length  of  the  fish;  the  ventral,  one-sixth.  The  dorsal  and  anal  fins  are  higher 
than  in  B.  decadactylus,  and  the  insertion  of  the  anal  is  under  the  end  of  the  dorsal. 
Caudal  deeply  forked.  Scales  large,  the  whole  surface  spinous,  with  short  refiexed  points  or 
prickles,  giving  a  general  roughness  to  the  touch.  Lateral  liue  nearly  straight,  following 
the  curvature  of  the  back,  inconspicuous,  and  with  71  to  76  scales,  with  8  above  and  20  be- 
below  the  lateral  line  in  transverse  series.  Its  color  is  thus  described  by  Lowe:  uAt  the 
moment  of  capture,  whilst  this  fish  is  yet  alive,  the  whole  body  beneath  the  lateral  line  is  of 
a  pure,  resplendent,  silvery  white;  the  fins  alone,  and  merely  the  ridge  of  the  back  and  head, 
the  inside  of  the  mouth,  the  lower  jaw,  and  parts  beneath  the  eye,  beiug  of  the  brightest 
scarlet,  contrasting  strongly  with  the  pure  silver  of  the  whole  sides  and  belly,  which  only 
after  death  turn  iridescent-rosy,  or  sometimes  rich  golden  scarlet.  The  hind  parts  of  the 
dorsal  and  the  ventral  fins  are  transparent ;  the  iris  is  pale  scarlet.  There  is  a  watery  trans- 
parency about  the  scarlet  of  the  back  in  this  state  perfectly  inimitable  by  art. 


DISCUSSION  OF   srECIES   AND   THEIR   DISTRIBUTION.  177 

"The  fishermen  affirm  correctly  that  this  superior  degree  of  « triteness  when  first  c;i|. 
fined  is  constant  in  this  species,  their  Alfonsin  d  casta  cumprida,  as  compared  with  /;. 
deeadactylus,  Cuv.,  their  Alfonsin  a  casta  larga,  which  is  from  the  first  more  generally 
scarlet  or  high  colored.  It  is  also  remarkable  that  the  pale-colored  month  is  characteristic 
of  the  outwardly  richer  colored  species;  while,  in  the  paler,  B.  splendens,  the  mouth  inter- 
nally  is  full  bright  red." 

Radial  formula:     D.  iv,  13-15.    A.  iv,  25-29.     V.  i,  7  +. 

This  species,  originally  described  by  Lowe  in  1833,  was,  as  has  already  been  stated, 
erroneously  represented  in  the  t  'ambridge  Philosophical  Transactions,  by  a  figure  of  the  other 
species.  In  Madeiran  waters  it  is  equallj  abundant  with  Jl.  deeadactylus,  bul  it  has  not  been 
identified  from  the  Lusitanian  coast.  A  single  specimen  was  obtained  by  the  steamer 
Albatross  at  a  depth  of  424  fathoms  from  station  2415,  in  35°  49' 30'' N.  lat.,  74°  34'  45"  \V. 
Ion.,  and  the  British  Museum  has  lately  secured  specimens  from  Japan. 

Lowe  records  the  following  singular  observations:  "One  singular  distinction  which 
exists  between  this  fish  and  /.'.  deeadactylus,  Cuv.,  is  the  comparatively  rapid  decomposition 
of  the  viscera.  I  have  repeatedly  had  individuals  of  both  sorts  brought  for  examination, 
which  had  been  caught  together,  and  while  the  whole  contents  of  the  abdomen  in  />.  deea- 
dactylus have  been  in  the  most  perfect  preservation,  those  of  B.  splendens,  though  in  other 
respects  the  fishes  were  quite  fresh,  have  proved  entirely  decomposed.  And  1  have  only 
been  able  to  overcome  this  difficulty  by  going  out  in  the  fishing  boats  aud  being  present  at 
the  actual  capture  of  this  latter  species,  the  Alfonsin  d  casta  cumprida  of  the  fishermen; 
which  begins  to  be  met  with  of  small  size  at  tin'  depth  of  150  or  200  fathoms,  but  is  scarcely 
taken  in  full  size  and  plenty  except  with  its  congener.  /.'.  deeadactylus,  Cuv.,  the  Alfonsin

from  the  shore."

The  greatest  depth  of  the  body  below  the  origin  of  the  dorsal  fin  equals  the  depth  below 
the  occiput,  and  is  rather  more  than  one  fourth  of  the  total  length  (without  caudal),  the 
length  of  the  head  being  one-third.  The  head  is  but  little  compressed,  but  higher  than 
broad,  aud  longer  than  high;  the  snout  is  very  obtuse,  with  the  lower  jaw  scarcely  project- 
ing beyond  the  upper:  maxillary  extending  to  behind  the  vertical  from  the  posterior  mar- 
gin of  the  eye;  eye  small,  its  diameter  being  one-sixth  of  the  length  of  the  head,  and  two 
thirds  of  that  of  the  snout;  crown  of  the  head  very  convex',  divided  by  ridges  (which 
are  angularly  bent)  into  a  central  rhomboid  portion  and  into  a  pair  of  lateral  ones:  the 
skiu,  extending  from  ridge  to  ridge  and  covering  the  muciferous  channels,  is  finely  and  lon- 
gitudinally plaited,  and  pierced  at  regular  intervals  by  very  small  pores.  The  operculum 
has  a  membranaceous  margin;  the  gill  membrane  perfectly  free  from  the  isthmus,  and  not 
united  with  that  of  the  other  side;  there  are  four  perfect  gills,  but  the  pseudobranchise  arc 
small.  Head  entirely  SCaleleSS.

178  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

The  distance  between  the  origin  of  the  dorsal  fin  and  the  end  of  the  snout  is  nearly 
equal  to  that  between  the  dorsal  and  caudal  fins;  its  spines  are  very  feeble,  gradually  in- 
creasing in  length  behind,  the  second  soft  ray  being  the  longest,  but  much  shorter  than  the 
base  of  the  fin.  The  anal  fin  is  small,  with  the  spines  very  feeble ;  and  there  arc  not  more  than 
two  in  the  specimen  from  which  this  description  is  taken,  while  Mr.  Lowe  says  that  he  has 
found  four  spines  in  the  first  specimen  which  was  discovered.  The  base  of  the.  anal  fin  is 
covered  with  rather  large  scales.  Caudal  fin  small,  forked,  covered  with  scales  at  the  base; 
pectoral  falciform,  not  quite  as  long  as  the  head,  and  not  extending  on  to  the  vent;  ven- 
trals much  shorter,  with  the  spine  very  feeble.  The  scales  are  large,  especially  on  the 
trunk,  with  the  margin  irregularly  notched;  they  become  smaller  on  the  tail,  but  the  tho- 
racic region  is  covered  with  very  large  ones,  especially  one  between  the  ventrals,  being  not 
much  smaller  than  the  operculum.    Lateral  line  none.    Color,  entirely  black.     (Giinther.)

PLECTROMUS,    Gill. 

Plectromua,  Gill,  Proc.  U.  S.  Nat.  Mus.  VI,  1883,  257,  258.— Bean.  „p.  cit.,  1885,  73.— Jordan,  Cat.  Fish.  N.  A., 

1885,  74. 

Berycine  fishes,  resembling  in  form  Melamphaes,  with  moderate  cycloid  scales.  Head 
large  and  thick,  with  wide  muciferous  channels,  and  often  with  conspicuous  foliaceous  con- 
tinuations of  the  superficial  bones.  Cleft  of  mouth  moderate,  somewhat  oblique.  Jaws 
nearly  equal,  though  the  under  one  is  slightly  the  more  prominent.  Teeth  villiform  in  the 
jaws  (in  the  type  species,  P.  suborbitalis),  arranged  in  two  rows,  of  which  those  of  the  inner 
row,  at  least  in  the  lower  jaw,  are  largest ;  palatines  toothless.  A  single  dorsal,  with  2  to  3 
spines  and  10  to  10"  rays.  Vent  and  origin  of  the  anal  under  the  last  rays  of  the  dorsal, 
the  anal  fin  with  1  spine  and  8  to  9  rays.  Ventrals  thoracic,  and  with  7  rays  as  in  Mel- 
amphaes. Branchiostegals  vni;  pseudobranchiae  present;  opercles  not  armed.  Caudal 
forked. 

The  genus  Plectromus,  which  has  been  united  with  Melamphaes  by  European  ichthy- 
ologists, is  provisionally  maintained  in  this  work  on  account  of  certain  apparently  valid 
characters,  such  as  the  more  normal  position  of  the  anal  fin,  which  is  inserted  under  the 
end  of  the  dorsal  rather  than  far  back  as  in  the  typical  Melamphaes;  also  by  the  much 
smaller  number  of  spines  in  the  dorsal  and  the  larger  number  of  rays  in  the  anal,  which 
appears  also  to  have  1  instead  of  2  antecedent  spines. 

Most  of  the  Atlantic  species  described  by  Giinther  appear  to  be  more  closely  allied  to 
the  Plectromus  type  than  to  Melamphaes  typhlops,  and  arc  provisionally  placed  in  the  genus 
Pleestromus  rather  for  the  purpose  of  eliciting  further  discussion  than  as  an  expression  of 
positive  opinion,  for  which  the  material  at  our  disposal  is  not  sufficient.  Melamphaes  eras- 
sleeps,  Giinther  (of  which  a  figure  is  given),  appears,  however,  to  be  a  very  close  ally  of  the 
species  described  by  Bean  under  the  same  specific  name. 

In  addition  to  the  several  Atlantic  species,  M.  in  yzolcpis,  Giinther  (Ann.  and  Mag.  Nat. 
Hist.,  1878,  II,  185,  Chall.  Beport,  xxn,  28),  obtained  by  the  Challenger  south  of  New  Guinea 
and  off  the  Arroe  Islands  at  800  fathoms,  and  by  the  Investigator  in  the  Bay  of  Bengal  at 
1,310  fathoms  (Aleoch,  Ann.  and  Mag.  Nat.  Hist.,  Sept.,  1890,  201),  seems  to  have  affinities 
with  Plectromus. 

The  following  details  concerning  the  genus  Plectromus,  as  represented  in  the  type 
species,  P.  suborbitalis,  are  furnished  by  Dr.  Gill: 

Body  little  compressed,  highest  behind  ventrals,  with  the  dorsal  outline  describing  a 
slight  sigmoidal  curve  and  the  abdominal  almost  rectilinear;  the  caudal  peduncle  long  and 
robust. 

Scales  moderate,  imbricated,  cycloid,  and  readily  deciduous. 

Lateral  line  apparently  undeveloped. 

Head  oblong  or  longer  than  high,  very  declivous  in  front,  and  with  the  suspensorium 
almost  vertical;  the  cranium  above  with  a  naked  skin  extending  from  the  nape  forward  to

the  nasal  region  covering  large,  muciferons  cavities  separated  by  osseous  bars  and  with  lat- 
eral crests  simulating  those  of  crested  Scorpaenids. 

Suborbital  bones  with  the  superficial  area  narrow  and  emitting  sulcate  spiuiform  pro- 
cesses; checks  covered  with  skin  as  well  as  periorbital  region. 

Preoperculum  with  its  inner  fold  parallel  with  but  widely  separated  from  the  external 
margin;  the  latter  is  rounded  at  the  angle,  the  posterior  limb  is  vertical,  and  a  short  hori- 
zontal one  is  developed. 

Operculum  normally  developed,  with  large  cycloid  scales,  and,  behind,  radiating  ridges; 
suboperculum  extending  as  a  membranous  border  behind;  interoperculum  moderate. 

Eye  moderate  (its  diameter  equaling  a  quarter  of  the  head's  length)  and  entirely  in  the 
anterior  half  of  the  head. 

Mouth  with  the  cleft  moderately  oblique. 

Upper  jaw  not  protractile;  the  intermaxillaries  protracted  backwards  almost  as  far  as 
the  superiuaxillaries;  the  latter  have  normally  dilated  smooth  ends. 

Lower  jaw  quite  deep,  curved,  with  smooth  skin,  with  the  rami  inclined  inwards  below 
and  nearly  contiguous,  and  with  a  truncate  chin. 

Teeth  rather  small,  curved,  and  pointed,  in  two  rows  iu  each  jaw,  those  of  the  upper 
closing  around  the  lower  jaw,  and  the  teeth  of  the  external  row  (at  least  in  the  lower  jaw) 
smaller  thau  those  of  the  internal. 

Branchial  apertures  normally  cleft. 

Shoulder  girdle  emitting  a  spine  on  each  side,  behind  the  nape. 

PLECTROMUS  SUBORBITALS,  Gill.     (Figure  201.)

A  species  of  Plectromus  having  the  length  of  the  head  contained  nearly  3  times  in  the 
total  without  the  caudal ;  the  height  of  the  body  3§  times.  The  diameter  of  the  eye  equals 
the  length  of  the  snout  and  is  contained  54  times  in  the  length  of  the  head.  Mouth  oblique ; 
the  end  of  the  maxilla  reaches  to  below  the  hind  margin  of  the  orbit.  Two  spiues,  one 
on  each  side  of  the  nape,  springing  forward  from  the  shoulder  bones,  give  a  strange  appear- 
ance to  the  fish,  and  have  gained  for  it  the  generic  name  Plectromus.  The  mandible  projects 
slightly.  Gill  membranes  deeply  cleft,  free  from  the  isthmus  behind,  gill-rakers  moderate, 
about  15  below  angle  of  1st  arch.  A  single  series  of  weak,  somewhat  scattered,  curved 
teeth  on  the  iutermaxilla  and  mandible. 

The  dorsal  origin  is  over  about  the  sixth  row  of  scales;  the  length  of  the  dorsal  base 
equals  length  of  head.  The  anal  origin  is  under  the  seventeenth  ray  of  the  dorsal;  the  anal 
base  is  nearly  one-third  as  long  as  the  head. 

The  pectoral  is  two-sevenths  of  the  total  length  without  the  caudal.  Theven  tral  origi- 
nates under  the  base  of  the  pectoral;  these  fins  are  imperfect. 

Radial  formula:  D.  in,  16;  A.  r,  S;  P.  14;  V.i,  7.  Scales  about  30;  transverse  series,  6; 
the  exposed  margins  of  the  few  scales  present  are  marked  with  coarse  concentric  stria?. 

Color,  black. 

The  type  of  the  species  (Xo.  33271,  U.  S.  N.  M.),  3$,  inches  long  without  the  caudal, 
which  is  imperfect,  was  obtained  by  the  Albatross  from  station  2030  iu  38°  52'  40"  K  lat., 
69°  24'  40"  W.  Ion.,  at  a  depth  of  1,735  fathoms.  Another  (No.  35451,  U.  S.  X.  M.)  was 
taken  from  station  21110.  in  39°  40'  1ST.  lat.,  70°  20'  15"  W.  Ion.,  at  a  depth  of  1,800  fath- 
oms; also  two  small  individuals  from  station  2535,  in  40°  03'  30"  X.  lat.,  07°27'  15"  W.  Ion., 
at  a  depth  of  1,149  fathoms.

toral  is  equal  in  length  to  the  head,  and  more  than  twice  as  long  as  the  ventral,  and  its 
tip  does  not  extend  quite  to  the  vent.  The  scales  are  large,  there  being  about  25  rows  in 
the  longitudinal  series. 

Radial  formula:  D.  n,  11-12;  A.  I,  8-9;  V.  I,  8;  P.  15. 

Color,  nearly  black;  the  fins  somewhat  lighter  at  the  margins. 

The  type  specimen  (Cat.  Xo.  33553,  V.  S.  N.  M.)  was  obtained  by  the  Albatross  from  sta- 
ti®n  2099,  in  37°  12'  20"  X.  hit.,  69°  39'  W.  Ion.,  at  a  depth  of  2,919  fathoms,  and  is  conse- 
quently remarkable  as  coming  from  the  greatest  depth  explored  by  the  Albatross,  and  the 
greatest  depth  from  which  any  tish  has  ever  been  obtained.  Its  length  is  18  millimeters, 
and  it  is  very  badly  preserved.  Other  specimens  were  obtained  by  the  Albatross  as  follows :

PLECTROMI'S  ROBUSTUS,  (Guntuer),  Goode  and  Bean. 
Melamphaes  robustus,  Gunther,  Challenger  Report,  XXII,  1887,  29. 

The  height  of  the  body  is  two-sevenths  of  the  total  length  (without  caudal) ;  the  length 
of  the  head  a  little  less  than  two-fifths;  the  least  depth  of  the  tail  is  two-fifths  of  its  free 
portion.  Head  thick,  with  the  usual  muciferous  cavities;  snout  short;  eye  very  small,  about 
one-eighth  of  the  length  of  the  head  ami  one  half  of  that  of  the  snout.  Posterior  margin

Height  of  the  body  one-fourth  of  the  total  length,  and  not  quite  equal  to  the  length  of 
the  head.  Eye  rather  large,  its  diameter  more  than  one-fourth  the  length  of  the  head,  and 
considerably  greater  than  that  of  the  snout.  Interorbital  space  in  its  greatest  width 
equal  to  about  half  the  greatest  height  of  the  body;  in  its  least  width,  one-fourth  the  great- 
est height  of  the  body.  The  caudal  peduncle  is  long  and  slender,  its  length  equal  to  the 
distance  from  the  posterior  root  of  the  anal  to  the  head;  its  height,  immediately  behind  the 
dorsal  and  anal  tins,  is  equal  to  one  half  the  greatest  height  of  the  body;  its  least  height, 
about  midway  between  the  dorsal  fin  and  the  caudal,  .scarcely  more  than  one-fourth  of  the 
height  of  the  body.  The  anal  is  inserted  under  the  last  rays  of  the  dorsal,  broadly  trian- 
gular in  form,  and  owing  to  the  rapid  diminution  in  the  height  of  the  body  under  the  dorsal 
and  anal,  both  of  these  fins  present  the  greater  portion  of  their  upper  margin  toward  the 
posterior  portion  of  the  fish.  The  pectorals  are  long,  leaf-like,  extending  beyond  the  roots 
of  the  dorsal  and  anal.  The  ventral  is  placed  entirely  in  advance  of  the  root  of  the  pecto- 
ral, and  is  very  broad  and  stout — almost  spatulate  at  its  extremity;  its  length  equal  to 
that  of  the.  pectoral,  and  its  tip  overlapping  the  anterior  portion  of  the  anal.  The  head  is 
very  rough,  foliaceous;  lower  jaw  prominent  and  projecting.     Color,  black.

This  species  was  described  by  Liitken  from  the  Atlantic,  south  of  the  Azores.  Its  pro- 
portions are  so  peculiar  that  it  seems  quite  possible  that  it  may  not  belong  either  to  Me- 
lamphaes or  Plectronms,  as  now  characterized.

Melamphaes,  Vaillant,  loc.  <//.,  385.  (part). 

Berycine  fishes  resembling  Melamphaes  and  Plectromus,  but  in  general  form  strongly 
suggestive  of  Myctophum.  Scales  moderate  and  cycloid,  regularly  arranged.  Head  thick 
and  comparatively  short,  with  deep  muciferous  channels.  Mouth  moderate,  somewhat 
oblique.  Jaws  nearly  equal,  the  lower  slightly  more  prominent.  Teeth  upon  the  inter- 
maxillary and  the  mandible:  palate,  vomer,  and  tongue  toothless.  Eyes  minute,  rudiment- 
ary. A  single  short  dorsal  of  about  12  rays  (number  of  spines  not  determined,  possibly 
rudimentary).  Vent  under  the  middle  of  the  base  of  the  dorsal;  origin  of  the  anal  under 
the  posterior  fourth  of  the  dorsal.  The  anal  tin  with  8  or  more  rays  (number  of  spines,  if  any 
not  rudimentary,  not  determined).  Ventral  tins  thoracic  and  with  ten  rays.  Pseudobran- 
chiae  present.     No  swim  bladder. 

This  genus,  was  founded  by  Vaillant  upon  the  five  specimens  of  a  species  described  by 
him  under  the  name  of  S.  coeles.  The  material  studied  by  him  was  badly  preserved,  and  the 
diagnosis,  especially  of  the  vertical  tins,  is  unsatisfactory.  At  first,  led  by  superficial  re- 
semblance, the  form  was  believed  to  belong  close  to  the  old  genus  Scopelus,  and  the  unfortu- 
nate name   Scopelogadus  is  intended  to  describe  a  Scopelus-like  fish  with  thoracic  tins.    In

an  appendix  to  his  great  work,  Yaillant  expresses  the  opinion  that  he.  had  erred  in  forming 
a  new  genus,  and  that  it  belongs  properly  to  Helamphaes,  of  Gunther. 

Scopelogadus  is  well  distinguished  from  both  Melampkaes  and  from  Plectromus  by  vari- 
ous characters,  most  prominent  of  which  are  the  short  head,  comparatively  small  mouth, 
rudimentary  eye,  and  short  dorsal  and  anal  tins,  which  overlap  to  the  extent  of  nearly  a 
third  of  the  length  of  each.

length  of  pectoral  equal  to  that  of  the  head,  its  tip  extending  far  behind  the  vent  and  to 
the  vertical  from  the  ba  se  of  the  antepenultimate  dorsal  ray;  length  of  the  ventral  about 
half  that  of  the  pectoral,  its  tip  not  reaching  to  the  vent.  Scales  large,  about  21  in  the 
longitudinal  series — 2  above  and  i  below.  Dorsal  placed  midway  between  the  snout  and 
the  base  of  the  upper  caudal  rays  (not  the  an  teeedent  rudimentary  spines).  Origin  of  the 
anal  under  the  base  of  the  preantep  cnultimate  dorsal  ray,  the  dorsal  overlapping  it  nearly 
one-half  of  its  leng  tli.

A  long  description,  accompanied  by  several  figures  of  anatomical  details,  is  given  by 
Yaillant.  The  species  was  described  from  four  specimens  obtained  on  the  Banc  D'Arguin 
at  depths  of  from  1,000  to  1,250  meters,  and  off  the  Cape  Verde  Islands  at  3,655  meters. 

MALACOSARCUS,  Gunther. 
Malacosarcus,  Gunther,  Challenger  Report,  xxn,  30. 

Head  large  and  thick,  with  bones  very  thin,  and  with  wide  and  deep  muciferous  cavi- 
ties; also  the  canal  along  the  lateral  line  is  much  distended.  Cleft  of  the  mouth  wide, 
obliquely  descending  backwards,  with  jaws  nearly  equal  in  front.  A  narrow  band  of  villi 
form  teeth  in  both  jaws;  palate  toothless.  Eight  branchiostegals,  pseudobranchia?  present. 
The  edges  of  the  preoperculum  and  the  lower  edge  of  the  mandible  with  minute  and 
distant  spines.  Scales  extremely  thin,  not  sculptured,  deciduous,  irregular,  and  of  moderate 
size.  One  dorsal;  caudal  emarginate,  with  broad  basal  fold  above  and  below;  anal  spines 
very  feeble.  Veutrals  small,  five-rayed,  inserted  at  some  distance  behind  the  pectorals. 
Gills  four;  gill-lamina'  short;  gill-rakers  long,  needle-shaped.     (Giinther). 

Although  this  fish  is  only  a  degraded  form  of  Melamphaes,  Giinther  decided  to  make  it 
the  type  of  a  distinct  genus,  since  otherwise  the  generic  definition  of  Melamphaes  would 
lose  much  in  precision. 

This  peculiar  genus  is  represented  by  the  single  species  M.  macrostoma,  Giinther  (Ann. 
and  Mag.  Nat.  Hist.,  1S7S,  vol.  n,  p.  18(3;  Challenger  Report,  Vol.  xxn,  p.  30),  obtained  in 
the  mid-Pacific,  Challenger  station  271,  at  a  depth  of  2,425  fathoms,  3i  inches  long;  and 
near  the  Low  Archipelago,  station  270,  at  a  depth  of  2,350  fathoms,  3i  inches  long.  No 
vestige  of  it  has  yet  been  found  in  the  Atlantic.

Body  short,  compressed,  scopeliform,  covered  with  thin,  cycloid  scales.  Head  very 
large,  nearly  half  the  entire  length  of  the  fish  to  base  of  caudal,  with  scales  upon  cheeks, 
suboperculum,  and  probably  elsewhere.  No  barbel.  Mouth  very  large,  the  lower  jaw 
projecting.  Margin  of  upper  jaw  composed  of  a  short  intermaxillary  and  a  long  maxillary. 
Teeth  cardiforin,  numerous,  very  small,  on  the  intermaxillaries  and  mandibles:  none  dis- 
covered on  maxillaries,  palatines,  or  vomer.     Opercular  apparatus  complete. 

Dorsal  fin  in  the  middle  of  the  body,  its  origin  not  far  behind  that  of  the  veutrals,  the

Height  of  the  body  two  sevenths  of  its  length  to  base  of  caudal  rays;  its  width  about 
one  half  its  height.  Scales  as  large  as  the  pupil,  with  concentric  stria',  about  twenty-four 
in  the  lateral  line  and  about  ten  in  the  transverse  series. 

Head  about  two-fifths  of  standard  length,  somewhat  resembling  in  appearance  that  of 
Mi  I>iii-(  jihiihi\  Bairdii.  The  eye  is  large,  circular,  located  normally.  The  length  of  the 
upper  jaw  is  three  sevenths  that  of  the  head;  that  of  the  lower  jaw  about  one  half.  The 
end  of  the  maxillary  is  nearly  in  the  perpendicular  from  the  posterior  limb  of  the  pupil. 
The  length  of  the  snout  is  about  equal  to  the  least  diameter  of  the  eye.  The  distance  from 
the  limb  of  the  preoperculum  to  the  end  of  the  opercular  Hap  is  equal  to  that  from  the  tip 
of  the  snout  to  the  posterior  margin  of  the  orbit.  Teeth  as  described  in  generic  diagnosis. 
Dorsal  flu  inserted  midway  between  tip  of  snout  and  origin  of  middle  caudal  rays.  The  fin 
is  mutilated  and  its  outline  can  not  be  determined;  it  is  composed  of  7  or  8  spines  and  (! 
soft  rays,  and  the  length  of  its  base  is  nearly  equal  to  the  height  of  the  body  at  its  insertion. 

The  anal  fin  is  inserted  in  the  perpendicular  from  the  base  of  the  eighth  dorsal  ray.  It 
is  composed  of  nine  rays,  and  the  length  of  its  base  is  half  that  of  the  dorsal  base. 

The  pectoral  is  inserted  far  below  the  axis  of  the  body,  and  with  a  single  scale  between 
its  axil  and  the  branchial  opening.    Its  length  is  twice  the  distance  of  its  insertion  from  snout. 

The  ventral  is  minute  (apparently)  and  is  inserted  in  advance  of  the  pectoral;  it  has 
about  7  or  8  rays. 

The  caudal  is  mutilated,  but  seems  to  be  composed  of  15  rays.

Berycids  with  a  laterally  oval  or  broad  pyriform  contour,  a  compressed  body  covered 
with  small,  pedunculated,  leaf  like  scales,  an  abruptly  declivous  forehead,  small  eyes,  a  pair 
of  very  long,  pointed  teeth  in  fronl  of  upper  jaw  closing  in  front  of  lower,  a  similar  pair  of 
still  longer  pointed  teeth  in  the  lower,  received  in  fovea'  of  the  palate;  on  the  sides  of  each 
jaw  two  long  teeth  terminating  in  bulbous  tips;  a  row  of  minute  teeth  on  the  posterior  half 
of  the  supramaxillaries,  and  a  toothless  palate. 

This  genus,  closely  related  to  Anoplogaster,  is  represented  by  a  single  Atlantic  species. 
The  details  of  its  structure  are  described  more  fully  in  the  following  notes  communicated  in 
manuscript  by  Dr.  Gill: 

Body  compressed,  pyriform, highest  in  front,  and  with  the  dorsal  and  inferior  outlines 
converging  to  caudal  peduncle,  which  is  moderately  Long  and  slender. 

Scales  small  and  not  or  scarcely  imbricated,  upraised  by  peduncles,  and  with  the  sur- 
face extended  and  dentate  behind. 

Lateral  line  distinct  and  developed  as  a  groove  running  parallel  with  the  back  and 
continuous  to  the  base  of  the  caudal  tin. 

Head  higher  than  long,  with  the  cranial  portion  very  declivous,  and  with  the  snspen- 
sorial  portion  obliquely  extended  downwards  and  backwards;  the  cranium  above  with  three 
naked  membranous  areas,  an  anterior  pair  pointed  forward  and  diverging  to  receive  the 
ascending  process  of  the  intermaxillaries  and  a  median  hastiform  one  behind;  also  with  a 
naked  horseshoe-shaped  area  around  the  nape;  the  naked  spaces  being  separated  by  the 
bony  bars  limiting  the  large  muciferous  cavities;  suborbital  bones  enlarged,  sculptured,  and 
with  small,  erect  spines;  the  first  with  three  radiating  bars;  the  second  largest,  sending 
four  depending  processes,  three  forward  or  downward,  and  another  articulating  with  the 
preoperculum  above  its  angle;  the  postorbital  expanding  distally  and  articulating  with  the 
preoperculum  above;  the  interspaces  covered  by  a  tense  skin  with  the  extension  of  the  scales 
imbedded  in  it. 

Preoperculum  angulated  downward  and  backward,  spinigerous  at  the  angle  and  with 
no  horizontal  lines:  opercular  apparatus  much  reduced ;  the  operculum  extended  downward, 
with  numerous  stria'  and  ridges  and  with  three  more  diverging  ridges  extended  backwards 
or  downward  into  spiniform  angles,  one  horizontal  and  the  others  oblique,  leaving  emar 
ginated  interspaces  between;  the  inter-  and  subopercula  small,  the  latter  with  several  strise 
pointed  backward. 

The  eye  moderately  developed  near  the  anterior  profile.  Upper  jaw  not  protractile, 
with  the  intermaxillaries  extended  far  backward  and  the  supramaxillaries  lying  behind  and 
above,  and  with  wide  oval  extremities  furnished  with  radiating  ridges  or  striae.

STEPHANOBERYX  MON^E,  Gill.     (Figure  205.) 

Stephanoberyx  Monce,  Gill,  Proc.  U.  S.  Nat.  Mus.,  vi,  1883,  258. 

The  type  of  the  species  is  a  young  specimen,  about  2  inches  long.  For  comparison 
with  S.  Gillii  we  have  used  examples  measuring  44  inches  from  Albatross  station  231)2. 

In  one  of  these  the  eye  is  two-ninths  as  long  as  the  head  and  nearly  equal  to  the  snout; 
the  head  equals  one-third  of  total  length  to  caudal  base,  the  greatest  depth  of  the  body 
two-sevenths  of  the  same  length.  The  upper  jaw  is  slightly  loiiger  than  the  postorbital 
part  of  the  head.  Gill-rakers  long  and  slender,  about  25  below  the  angle  on  the  first  arch. 
The  distance  of  the  anal  origin  from  the  end  of  the  head  equals  two-thirds  length  of  head. 
The  ventrals  originate  under  the  middle  of  the  pectorals. 

Color,  brownish.

709  fathoms. 

STKl'IIAM  IBERYX  GILLII,  Goode  and  Bean,  n.  s.     (Figure  206.) 

The  type  specimen  is  Xo.  33555,  U.  S.  Nat.  Museum,  obtained  from  Albatross  station 
20!)'.);  its  Length  is  0  inches.  Two  additional  examples  from  Albatross  station  2102  have  also 
been  used  lor  the  purpose  of  this  description ;  one  of  these  is  1^  inches  long  and  the  other 
5A  inches. 

The  diameter  of  the  eye  equals  length  of  snout  and  one-fourth  length  of  head,  which  is 
one-third  of  total  length  to  caudal  base.  Greatest  depth  of  body  two-sevenths  of  total  with- 
out caudal.  The  upper  jawis  as  long  as  the  postorbital  part  of  the  head.  Gill-rakers  long 
and  slender,  about  15  below  the  angle  on  the  first  arch.  The  ventral  origin  is  behind  the 
end  of  the  extended  pectoral.  The  distance  of  the  anal  origin  from  end  of  head  fully  equals 
length  of  head. 

About  33  rows  of  scales  from  bead  to  base  of  caudal ;  9  rows  above  and  7  below  the 
lateral  line. 

Radial  formula:  B.  7;  D.  11;  A.  11;  P.  13;  V.  i,  5. 

Color,  in  spirits,  pale,  the  back,  in  front  of  dorsal,  showing  traces  of  rose. 

The  species  may  readily  be  distinguished  from  8.  motive  by  its  smaller  number  of  dorsal 
and  anal  rays  and  gill-rakers,  the  position  of  its  ventrals,  and  the  greater  length  of  its 
trunk. 

Specimens  were  obtained  from  Albatross  stations  2099  (2,919  fathoms),  2102  (1,209  fath- 
oms), and  2190  (1,230  fathoms). 

Family  TRACHICHTHYID^E. 

Traehiehthyoidei,  Bleekei:,  Tentamen,  18.~>9,  xix.     (Familia  73). 

Body  ovate,  deep,  much  compressed,  with  small  or  moderate  ctenoid  scales.  Abdo- 
men protected  by  a  dermal  scute,  forming  a  serrated  edge.  Head  large,  deeper  than  long; 
superficial  bones  excavated,  and  with  conspicuous  muciferous  cavities.  Mouth  very  wide, 
oblique.  Villiforin  teeth  in  the  jaws  and  on  the  vomer.  Suborbitals  very  broad,  covering 
the  checks.  Branchiostegals  8.  Gill-openings  wide;  gill-lamimn  very  short.  A  single  dorsal 
tin,  with  a  few  anterior  spinous  rays.    Ventrals  with  6  soft  rays. 

In  this  family  are  included  two  genera:  Trachichthys,  with  teeth  upon  its  vomer,  oper- 
culum with  spine,  and  with  two  anal  spines,  and  Uoplostethus,  with  toothless  vomer,  opercu- 
lum entire,  and  3  anal  spines.

Body  compressed,  more  or  less  deep,  covered  with  small  ctenoid  and  generally  rough 
scales,  which  are  rather  it  regularly  arranged.  Abdomen  protected  by  dermal  scutes,  which

spinous;  veutrals  with G  soft  rays;  pectoral  symmetrical;  caudal  deeply  forked.  (Giinther.) 
Eight  species  of  Trachichthys  are  known,  of  which  one  is  found  in  the  Atlantic,  and  all 
of  these  have  been  described  from  floating  specimens,  presumably  originating  in  the  ocean 
depths.  T.  intermedins,  however,  was  obtained  by  the  Challenger  near  New  Zealand,  at  a 
depth  of  275  fathoms,  and  by  the  Investigator  in  the  Bay  of  Bengal,  272  fathoms;  and 
previously  by  Hector,  off  Cape  Farewell,  New  Zealand,  in  400  fathoms.  (Hector,  Tr.  New

The  height  is  two-fifths  of  the  total  length  to  base  of  caudal.  The  head  is  two- 
sevenths  of  the  total  length.  Mouth  very  large  and  nearly  vertical.  Its  superior  border 
formed  by  the  styliform  iutermaxillary.  A  wide  notch  at  the  symphysis  of  the  intennaxil- 
laries.  Maxillary  long  and  stout,  dilated  below,  with  a  large  supplementary  striate  plate,  as 
in  Beryx.  The  maxillary  reaches  the  vertical  from  the  middlle  of  the  eye.  Lower  jaw 
included,  its  bones  strongly  and  deeply  striate.  Intermaxillary  and  mandible  with  narrow 
bands  of  villiform  teeth,  the  innermost  row  a  little  enlarged.  Bands  of  villiform  teeth  on 
the  palate.  A  small  round  patch  of  similar  teeth  on  the  vomer.  Nostrils  close  together 
near  the  upper  anterior  part  of  the  orbit,  the  posterior  the  larger.  Eye  nearly  round, 
placed  high,  but  not  reaching  the  profile,  its  length  4£  times  in  that  of  the  head.  Edge 
of  opercle  irregularly  sen-ate  or  sinuous.  A  spine  at  the  lower  end  of  the  subopercle. 
Large,  imbricated,  striate,  bony  plates  (ten  in  the  specimen)  form  a  ventral  keel  extending 
from  the  root  of  the  ventral  fin  to  the  vent,  increasing  in  size  from  each  end  of  the  series 
to  the  middle.  Dorsal  origin  behind  the  root  of  the  pectoral;  nearer  the  snout  than  the 
base  of  the  caudal.  The  fourth  dorsal  spine  the  longest.  Soft  dorsal  higher  than  spinous, 
the  third  and  fourth  rays  longest.  A  series  of  large,  rough  scales,  somewhat  trapezoidal 
in  shape,  at  each  side  of  the  dorsal  and  anal  tins.  The  pectoral  does  not  reach  nearly  to 
them,  but  to  the  vertical  of  the  seventh  dorsal  spine.  Ventral  inserted  under  root  of  pec- 
toral, consisting  of  a  long,  stout,  striated  spine  and  six  branched  rays.  Caudal  deeply 
forked,  membrane  between  its  rays  covered  with  rows  of  small  scales.  Lateral  line  on  the 
upper  part  of  the  body,  not  following  the  curve  of  the  back.    , 

The  head  and  all  the  flusareof  abrightred  color;  the  back  is  of  brownishred,  passing 
into  gray  on  the  sides;  the  belly  is  white,  tongue  black;  also  the  iusidc  of  the  mouth  and 
gill-covers.  Sometimes  the  inside  of  the  gill-covers  is  marked  with  black  patches.  Palate 
red. 

Radial  formula:  D.  vni,  14;  A.  in,  12;  V.  I,  6;  L.  lat.,  27.     Pyloric  caeca  13. 

This  species  differs  from  the  Antarctic  one  in  having  the  bones  of  head  more  solid,  nar- 
rower, muciferous;  a  smaller  eye  and  the  spinous  dorsal  fin  more  differentiated  from  the 
soft.  The  scales  are  small.  Abdominal  scutes  ten.  The  height  of  the  body  is  less  than 
half  the  total  length  (without  caudal);  the  diameter  of  the  eye  two-ninths  of  the  length  of 
the  head.  No  projecting  suprascapulary  spine.  The  third  and  fourth  dorsal  spines  are 
the  longest,  and  the  seventh  is  shorter  than  the  eighth. 

Only  one  specimen,  19  inches  long,  was  obtained  off  Madeira  in  the  month  of  April.  Mr. 
Johnson  adds  that  from  the  protruded  stomach  and  inflated  membrane  about  the  eye,  it 
may  be  inferred  that  the  fish  came  from  a  great  depth.  Like  so  many  other  Madeiran 
fishes,  this  species  occurs  also  in  Japan,  where  it  was  met  with  by  Doderlein,  who  seems  to 
have  been  unacquainted  with  Johnson's  description.     (Giinther.)

Specimens  of  this  species  have  been  discovered  at  distant  intervals  of  time  at  consid- 
erable depth  (the  precise  depth  is  not  known)  in  the  western  parts  of  the  Mediterranean, 
off  Madeira,  and  recently  also  in  the  sea  of  Japan.  Dr.  Hilgendorf  was  of  opinion  that 
he  could  specifically  distinguish  Japanese  specimens  by  a  somewhat  larger  number  of  ab- 
dominal scutes.  This  would  have  been  a  character  insignificant  enough,  even  if  the  Japan- 
ese specimens  had  not  sometimes  the  same  number  of  scutes  as  the  Mediterranean.  A 
more  important  difference  seems  to  be  the  structure  of  the  scales,  which  I  find  in  Japanese 
specimens,  on  the  whole,  less  strongly  ctenoid  than  the  Madeiran.  But  even  in  this  respect 
there  is  no  constancy  in  specimens  from  either  of  the  two  localities.     (Giinther.)

3£  times  in  the  length  of  the  head.  The  scales  are  very  small  (much  more  so  than  in  H. 
mediterrameus),  the  diameter  of  the  scales  of  the  body  being  one-seventh  that  of  tbe  scales 
of  the  lateral  line;  they  are  nearly  circular,  and  have  a  few  little  spines.  Ventral  keel  in- 
distinct.   Dorsal  and  anal  spines  feeble.    Yentrals  extending  scarcely  to  the  vent. 

Radial  formula:  D.  vi,  17;  P.  i,  17;  v.  I,  0;  A.  n,  11;  C.  vn,  18,  8. 

This  species  is  distinguished  from  11.  mediterraneus  by  the  relatively  smaller  size  of  its 
eyes  and  scales,  by  the  indistinct  ventral  cuirass,  and  by  the  greater  number  of  rays  in  the 
fins.  The  type  was  a  single  specimen  taken  off  Flores  in  the  Azores,  July  30, 1888,  by  the 
steam  yacht  Hirondelle  at  a  depth  of  1,557  meters.

spaces;*  seven  branchiostegals;  a  first  dorsal  with  about  five  weak  spines,  the  second  and 
anal  oblong,  and  normal  thoracic  ventrals  (i,  5).     (Gill,  MS.) 

This  family  is  represented  by  a  single  species  and  a  single  genus — Anomalops  palpe 
bratus  (Boddaert),  Giinther,  known   only  from  eight    specimens,  four  from  Amboina   and 
Manado,  one  from  the  Fiji  Islands,  one  from  the  Fauiuoto  Archipelago,  and   two  others 
from  the  New  Hebrides,  the  types  of  Ogilby's  recent  valuable  paper,  "Eedescription  of 
Anomalops  palpebrarum."    (Records  of  the  Australian  Museum,  Sydney,  i,  1S90,  69-71.) 

This  form  was  placed  by  Giinther  in  the  family  Carangidas,  but  this  assignment  was 
professedly  provisional,  since  he  had  never  been  able  to  examine  the  specimens.  The  origi- 
nal assignment  by  Bleeker  and  Kner  to  the  Hcri/rida:  was  more  nearly  exact,  but,  as  Dr. 
Gill  has  shown,  it  seems  to  possess  positive  and  distinctive  family  characters  of  its  own. 

ANOMALOPS,  Kner. 

Anomalops,  Kner,  Sitzungsberichto  Akad.  Wiss.  Wien.,  lviii,  1868,  p.  294,  pi.  I.,  Fig,  1. 

Body  oblong,  covered  with  small  rough  scales.  Snout  very  short  and  convex;  mouth 
very  wide.    Eyes  very  large;  a  glandular,  elongate,  and  partly  free,  luminous  organ  occu-

pies  a  hollow  of  the  infraorbital  ring  below  the  eyes.  Villiform  teeth  in  the  jaws  and  on  the 
palatine  bones;  vomer  toothless.  First  dorsal  short;  second  and  anal  moderately  long; 
caudal  forked.     (Giinther.) 

According  to  Giinther,  Anomalops  palpebratus  lives  in  great  depths,  and  comes  to  the 
surface  at  night  or  by  accident  only.  "The  peculiar  organ  below  the  eyes,"  he  writes,  "is 
without  doubt  of  the  same  nature  and  has  the  same  function  as  similar  structures  on  the 
side  of  the  head  of  other  deep-sea  fishes;  as  in  Pachystomias,  it  is  partly  free,  as  if  it  could 
be  made  to  protrude  out  of  the  pit  in  which  it  lies."

This  family  is  so  little  bathybial  in  its  range  that  it  may  be  passed  over  with  a  brief 
allusion.  The  family  includes  perhaps  two  hundred  species,  many  of  which  are  semipe- 
lagie  in  habit  but  which,  so  far  as  is  at  present  known,  live  near  the  shores  and  in  the  upper 
water.  There  is  no  evidence  that  any  of  them  breed  far  from  the  coasts,  except  it  may  by 
XaiicratfK.     Most  of  them  are  probably  restricted  in  range,  so  far  as   individual    migrations

are  concerned.  Seriola,  Oligoplites,  Trachynotus,  and  some  of  the  large  species  of  Carcmx, 
such  as  0.  hippos,  are  powerful  swimmers,  and  are  likely  to  make  long  journeys,  at  least 
as  far  as  from  the  West  Indies  to  the  Bermudas,  where  many  of  the  species  occur  casually. 
Others,  like  Selene,  drift  far  and  wide  with  the  currents,  and  are  found  in  mid  ocean, 
apparently  under  much  the  same  conditions  as  in  Xomens.  Nomeus  is,  however,  character- 
istically a  mid-ocean  lish,  and  is  not  known  to  breed  near  the  shores,  but  there  is  good 
reason  to  believe  that  Selene  does. 

Seriola  Dumcrilii,  Risso,  is  said  by  Canestrini  to  occur  everywhere  in  the  Mediter- 
ranean, but  to  dwell  at  great  depth  (a  grande  profondita),  so  that  its  capture  is  uncommon. 
The  young  of  Seriola  are  pelagic  surface  forms. 

Garanx  amblyrhynchus,  C.  &  V.  has  been  found  several  times  under  circumstances  which 
would  seem  to  indicate  that  it  came  from  very  great  depths,  but  it  so  closely  resembles  in 
structure  the  other  members  of  the  genus  that  it  is  hard  to  believe  that  there  is  not  some 
error  of  observation.  It  was  brought  up  by  the  Blake  at  station  324  (Lat.  33°  27",  Ion. 
75o  53'  30"),  in  G47  fathoms. 

Porthmeus  amia(Lichia  am  ia,  Auctorum,  in  its  adult  form — Porthmeus  argenteus,  in  young 
state)  is  while  young  a  pelagic  form,  and  has  been  found  off  the  west  coast  of  Africa.  The 
young  of  Chorinemus  and  of  Oligoplites  are,  according  to  Liitkeu,  also  pelagic  (Spolia  At- 
lautica,  p.  192  (600)).  Two  species  belonging  to  this  family  have  been  taken  in  the  deep- 
sea  nets,  but  it  seems  hard  to  believe  that  they  were  caught  at  the  bottom.

Physoclystous  Aeanthopterygians,  with  body  elongate,  fusiform;  the  scales  minute  or 
wanting  (generally  cycloid,  but  about  the  thorax  larger  ones,  sometimes  ctenoid,  are 
developed,  forming  the  so-called  corselet  of  the  tunnies).  Lateral  line  distinct,  frequently 
sinuous.  Head  subconic,  poiuted  anteriorly.  Mouth  rather  large,  with  lateral  cleft;  upper 
jaw  not  protractile;  maxillary  without  supplemental  bone;  sharp  teeth  on  the  jaws  and 
generally  on  the  vomer,  sometimes  on  palatines,  rreoperculum  entire;  operculum  well 
developed,  unarmed;  in  the  extremely  young  the  preoperculum  is  usually  armed  witli 
several  radiating  spines,  subsequently  absorbed  and  lost.  Gill-openings  large,  confluent 
below.  Gill-rakers  usually  long.  Pseudobranchire  present,  large.  A  slit  behind  the  fourth 
gill.  Brauchiostegals  generally  7.  Dorsal  fins  2,  the  first  composed  of  rather  slender, 
spinous  rays,  depressible  in  a  groove,  the  second  with  branched  rays,  the  posterior  ones 
usually  detached  and  separate,  forming  series  of  Unlets.  The  first  dorsal  is  always  either 
elongate  or  widely  separate  from  soft  dorsal.  Anal  similar  to  second  dorsal.  Caudal 
peduncle  very  slender,  usually  keeled,  the  caudal  deeply  forked,  adapted  for  rapid  propul- 
sion. Ventrals  moderate,  thoracic.  Vertebra  numerous  (more  than  25).  Pyloric  caeca 
well  developed,  numerous.     Stomach  sac-shaped.     Air  bladder  frequently  absent.

Subfamily  SCOMBRIN^E. 

Scombrids  with  fusiform,  moderately  elongate  bodies,  and  short  (less  than  lii  spines)  first 
dorsal  fin,  separated  by  a  wide  space  from  the  second  dorsal.  Pectorals  nigh  up.  Caudal 
nut  carinated. 

Several  of  the  forms  in  the  subfamily  occur  at  times  far  out  at  sea,  but  this  is  no  reason 
for  considering  them  properly  pelagic.  Like  the  common  mackerel  (Scomber  scombrus), 
which  also  is  found  in  schools  remote  from  land,  they  probably  all  breed  near  the  coasts, 
and  depend  for  their  food  upon  the  shoals  of  small  fishes  and  crustaceans,  which  are  abund- 
ant near  the  hind.  Scomber  spawns  at.  considerable  depths,  but  probably  never  beyond 
the  KMi  fathom  line.  It  is  probable  that  many  of  the  ScombHdcB  sink  at  times  far  below 
the  sin  face  strata,  especially  in  the  winter.  These  matters  are  but  little  understood,  tow- 
ever,  and  it  is  indeed  probable  that  our  knowledge  of  the  bathic  distribution  of  the  mem- 
bers of  the  mackerel  family  is  no  more  imperfect  than  our  supposed  knowledge  of  their 
geographic  range  and  migrations.  The  remarks  of  Valenciennes  in  the  "Histoire  Xaturelle 
des  lies  ( Janaries"  (Poissons,  p.  49),  though  written  fifty  years  ago,  are  worthy  of  consider- 
ation to-day. 

Subfamily  ORYCNIN^G. 

Scombrids  having  a  fusiform,  moderately  elongate  body,  ami  spinous  dorsal  long,  com- 
posed of  more  than  12  spines,  and  contiguous  to  the  second.  Pectorals  low.  Caudal  carinate. 
Pyloric  casca  very  numerous. 

The  tunnies,  bonitoes,  and  horse  mackerels  composing  this  family  are  even  more  charac- 
teristically pelagic  than  those  oi  I  he  preceding  subfamily,  but  never  have  as  ye1  been  found 
below  100  fathoms.  There  is  every  reason  to  suppose  that  at  times  they  sink  below  the 
upper  strata.

Thyrsitops  lepidopoides,  Gill,  Proc.  Acad.  Nat.,  Sci.,  Phila.,  1862,  126. 

A  Thyrsitops  with  a  somewhat  robust  body,  having  its  height  one-sixth  of  its  total 
length,  its  thickness  two-fifths  of  its  height.  The  lengi  h  of  the  head,  as  in  pretiosus,  is  one- 
fourth  of  the  total  length.  Nostrils  so  placed  that  the  anterior  is  midway  between  the  orbit 
and  the  tip  of  the  snout,  and  the  posterior  midway  between  the  anterior  and  the  orbit. 
Lower  jaw  passing  the  upper,  but  obtuse.  Teeth  in  the  jaws  small,  those  in  the  roof  of  the 
mouth  anteriorly  very  large  and  conspicuous.  A  row  of  teeth  on  the  vomer,  and  another 
along  each  palatine  bone,  small,  short,  and  sharp.  Tongue  smooth.  Operculum  deeply 
emarginate,  having  two  sharp  points,  flexible,  intruding  into  the  skin.  First  dorsal  low, 
uniform  in  height,  17  very  flexible  rays,  the  length  of  which  is  about  one  fourth  of  the 
height  of  the  body,  the  last  being  very  small.  The  length  of  the  base  of  this  fin  is  one- 
third  that  of  the  body.  The  second  dorsal  in  its  anterior  part  is  twice  as  high  as  the  first, 
and  its  length  is  twice  its  own  height.  It  is  composed  of  2  hidden  spines  and  14  rays,  and 
is  followed  by  4  finlets.  The  anal  is  similar  to  the  second  dorsal  in  position  and  size,  is 
composed  of  2  spines  and  15  soft  rays,  and  is  followed  by  4  finlets,  the  last  of  which 
looks  as  if  it  were  double.  The  length  of  the  pectoral  is  one-ninth  of  the  total  length. 
Ventral  two-thirds  as  long  as  the  pectoral.  The  head  and  the  most  of  the  body  appear 
to  be  smooth,  but  toward  the  end  of  the  tail  some  scales  are  visible.  The  lateral  line  is 
nearly  straight,  and  formed  of  a  series  of  little,  serrated  scales.  Color  silvery,  a  little 
darker  on  the  back;  the  lateral  line  brown,  fins  gray,  iris  golden.

The  types  of  this  species  were  sent  to  the  Muse~e  d'Histoire  Naturelle  from  Brazil  by 
Delalande,  and  were  a  foot  in  length.  The  species  is  undoubtedly  an  inhabitant  of  consid- 
erable depths.

THYESITOPS  VIOLACEUS,  Bean.    (Figure209.) 
Thyrsitaps  violaccus,  Bean,  Proo.  17.  S.  Nat.  Mus.,  1887,  pp.  513,  514. 

A  Thyrsitops  with  the  body  stout,  itsgreatest  width  being  exactly  one-halfof  the  height 
at  the  anal  origin.  The  greatest  height  of  the  body  is  one-half  of  the  length  of  thehead, 
and  is  contained  8  times  in  the  total  length  without  caudal.  The  length  of  thehead  is  one 
fourth  of  the  standard  length ;  its  greatest  width  is  contained  ££  times  in  its  length.  The 
width  of  the  interorbital  area  is  slightly  greater  than  the  length  of  the  eye,  which  is  con- 
tained nearly  7  A  times  in  the  length  oft  he  head  and  :>\  times  in  the  length  of  the  upper  jaw. 
The  least  height  of  the  tail  equals  the  width  of  t He  interorbital  area.  The  length  of  the 
snout  equals  twice  the  length  of  longest  dorsal  spine,  ami  one-half  the  distance  from  the 
tip  of  the  snout  to  the  origin  of  the  spinous  dorsal.  The  maxilla  extends  to  the  vertical 
through  the  front  of  the  eye.  The  length  of  theupperjaw  equals  3J  times  the  width  of 
the  interorbital  space.  The  mandible  reaches  to  the  vertical  through  the  hind  margin  of 
the  eye:  its  length,  including  the  fleshy  tip,  is  5  times  the  width  of  the  interorbital  area. 
The  anterior  nostril  is  smaller  than  the  posterior;  it  is  situated  in  advanceof  the  eye  one 
diameter  of  the  eye.  The  posterior  nostril  is  a  narrow  slit  placed  midway  between  the  ante- 
rior and  the  eye.  Strong  teeth  on  the  intermaxillary  and  mandible.  Three  large  fangs 
anteriorly  in  the  roof  of  the  month;  pseudobranchiae  well  developed;  no  trace  of  gill-rakers. 
Thespinous  dorsal  begins  at  a  distance  from  the  snout  which  equals  twice  the  length  of 
the  snout;  it  is  highest  in  the  middle.  The  ninth  and  thirteenth  spines  are  slightly  longer 
than  the  third  spme  and  more  than  twice  as  long  as  the  twentieth,  their  length  equaling 
one-half  that  of  the  snout.  The  soft  dorsal  is  highest  anteriorly,  its  longest  ray,  the  fifth, 
being  nearly  twice  the  least  height  of  the  tail.  The  caudal  is  forked;  its  middle  rays  about 
one-half  as  long  as  the  external  rays.  The  anal  origin  is  under  the  third  ray  of  the  soft 
dorsal,  its  distance  from  the  vent  2J times  the  length  of  the  dagger-shaped  spine.  The  vent 
is  directly  under  the  end  of  the  spinous  dorsal.  The  anal  rays  are  longest  anteriorly,  the 
fifth  ray  being  nearly  as  long  as  the  corresponding  ray  of  the  soft  dorsal.  The  dagger- 
shaped  spine  in  front  of  the  anal  equals  one-half  the  least  height  of  the  tail.  The  ventral 
is  immediately  under  the  third  spine  of  dorsal;  its  first  and  longest  ray  equals  three-fourths 
of  the  interorbital  width.  The  fifth  ray  is  about  two-thirds  as  long  as  the  first.  The  pec- 
toral begins  under  the  second  dorsal  spine;  its  length  equals  2i  times  the  width  of  the 
interorbital  area.     It  extends  to  the  vertical  midway  between  the  fifth  and  six  dorsal  spines. 

The  lateral  line  is  well  developed;  it  descends  gradually  from  the  upper  angle  of  the  gill 
opening,  reaching  the  median  line  of  the  body  under  the  soft  dorsal.  The  scales  are  irregu- 
lar in  shape,  thin,  elongate,  cycloid,  and  deciduous. 

Color,  purplish.     The  spinous  dorsal,  pectorals,  ventrals,  and  inside  of  mouth  blackish.

It  is  44  inches  long  to  the  base  of  the  middle  caudal  rays,  it  is  more  nearly  related  to 
lepidopoides  than  to  any  other  species;  in  fact,  it  is  not  very  closely  related  to  any  of  the 
others.  If  we  may  trust  the  figures  and  descriptions  of  I.  lepidopoides  our  new  species  has 
a  larger  number  of  dorsal  spines  and  rays  and  a  much  smaller  number  of  dorsal  and  anal 
Unlets.  T.  lepidopoides  is  said  to  be  uniform  silvery,  the  back  somewhat  plumbeous  and 
the  fins  gray.  Our  species  is  uniformly  purplish  brown,  the  spinous  dorsal,  pectorals,  ven- 
trals,  and  inside  of  the  mouth  blackish.

Suvettus,  Cocco,  Giorn.  Sci.  Sicilia,  xlii,  1829,  2.— Gill,  Proc.  Acad.  Nat.  Sci.,  Phila.,  1862,  126. 

I  !i  idy  fusiform  and  somewhat  elongated.  First  dorsal  with  less  than  25  spines.  Spinous 
dorsal  continguous  to  the  soft,  variable.  Pectorals  equidisant  from  the  back  and  breast,  or 
nearer  the  latter.  Abdomen  keeled.  Tail  not  keeled.  Ventrals  I,  5.  Dorsal  and  anal 
unlets  developed.  Dorsal  and  anal  unlets  2.  Lateral  line  obsolete.  Skin  with  bony, 
oblique  tubercles. 

There  have  been  two  supposedly  distinct  forms  described,  one  the  Ruvettus  pretiosus 
from  the  eastern  Atlantic  and  the  Mediterranean,  and  one,  the  Tfiyrsites  scholar  is  of  Poey, 
from  Cuba.  It  is  probable  that  Dr.  Giinther  is  right  in  believing  them  to  be  identical,  al- 
though no  one  except  Poey  has  examined  this  accidental  form,  and  the  two  have  never  been 
placed  side  by  side. 

liurcttus  is  no  doubt  similar  in  its  habits  to  the  closely-related  Thyrsitops,  which  de- 
cends  below  the  hundred-fathom  line.

A  Scombroid,  with  elongate,  fusiform,  somewhat  compressed  body;  its  height  is  equal 
to  one-sixth  of  its  length  (without  caudal);  the  length  of  its  head  about  one-fourth.  Ab- 
domen with  a  denticulated  keel.  Body  covered  with  bony  plates,  remote  from  each  other, 
and  armed  with  spines.  No  lateral  line.  The  maxillary  extends  beyond  the  vertical  from 
the  posterior  margin  of  the  orbit.  First  dorsal  fin  composed  of  15  spines,  IS  rays,  and  2 
separate  finlets ;  the  spinous  portion  received  in  a  furrow.  The  second  dorsal  nearly  simi- 
lar and  opposite.  Two  detached  anal  finlets.  Caudal  strongly  forked,  the  upper  lobe  the 
largest.  Color,  above,  blackish  brown ;  below,  dull  white,  the  bony  scutes  being  whitish

This  form,  first  described  from  the  Mediterranean,  occurs  about  Sicily ;  here  it  is  so  rare 
at  the  present  time  that  it  does  not  appear  to  have  a  common  name  among  the  fishermen, 
though  Canestrini  says  that  its  flesh  is  delicious.  Bonaparte  refers  to  it  as  Rovetto,  and 
the  fishermen  of  Catania  call  it  Pesci  Ruvetto.  Dr.  Anastasio  Cocco  first  described  it  from 
Messina.  Giglioli  has  observed  it  at  Genoa,  Naples,  Palermo,  Malta,  and  Spalato  (Dalma- 
tia)  and  at  Mce.    It  was  subsequently  found  by  Lowe  at  Madeira,  and  by  Webb  and  Ber-

thelot  at  the  Canaries,     tt  occurs  rarely  on  the  Portuguese  coast,  where  ft  is  failed  Esco 

lur,  and  doubtless  also  in  Spanish  waters.  About  the  Canaries  the  fish  is  known  as  the 
Escolar,  a  name  which  is  said  to  be  applied  to  members  of  the  family  Qadidas  by  Spanish 
fishermen.  The  Escolar  occurs  in  great  schools  about  the  Canaries  in  winter,  and  the 
fishermen  capture  it  with  hook  and  line  at  a  depth  of  a  hundred  fathoms  or  less,  and  its 
flesh  is  highly  prized.  Cantraiue  Btates  thai  it  is  taken  at  considerable  depths  about, 
Malta.  Lowe  found  it  at  Madeira  at  depths  as  great  as 300 and  400  fathoms.  It  was  found 
by  Poey  in  the  waters  of  Cuba  before  1854.  Poey  tells  us  that  it  is  rarely  seen  in  the 
markets  because  of  the  difficulty  attending  its  capture,  for  it  can  lie  caught  only  at  a  depth 
of  300  fathoms  on  dark  nights  in  September  and  the  early  part  of  October.  Poey  further 
states  that  when  one  of  these  fishes  is  brought  to  the  surface  it  appears  to  be  surrounded 
by  a  globe  of  phosphorescent  light.  The  Cuban  fishermen  go  "a  scholaring"  (it  escolarear) 
after  the  fishing  for  the  Spearfish  [Tetrapturus)  has  ceased,  and  before  that  for  the  lied 
Snapper  (Lutjanus  aya)  begins.  According  to  Canestrini  it  grows  to  the  weight  of  loo 
pounds  in  Sicilian  waters. 

In  1S91  a  specimen  (No.  43740,  U.  S.  N.  M.)  40  inches  in  length,  was  taken  on  Georges 
Bank,  in  about  41°  40'  N.  lat.,  67°  44'  W.  long.,  in  September.  It  was  obtained  by  the 
schooner  M.  A.  Boston,  Capt.  Thomas  Thompson,  of  Gloucester,  and  was  sent  by  the 
captors  to  the  C  S.  Fish  Commission.  Another  individual,  6  feet  long,  was  taken  from 
the  same  region  a  few  weeks  later.  This  also  was  sent  to  the  Fish  Commission,  and  was 
transferred  to  the  National  Museum,  where  its  skeleton  is  preserved.

lobe  the  smaller.  Ventral  under  the  lower  angle  of  the  pectoral.  Coloration  bluish,  lighter 
on  sides  and  belly,  fins  reddish  brown,  dorsal  opalescent,  iris  white.

Poey's  Epinnula  magistralis  was  known  from  a  single  specimen,  0S0  millimeters  long, 
obtained  at  Havana  in  September,  1853.  It  was  not  known  to  the  fishermen,  and  nearly 
forty  years  have  elapsed  since  its  capture.  Everything  would  seem  to  indicate  that  it  is  a 
dweller  in  the  depths  of  ocean  adjacent  to  Cuba. 

The  Albatross  obtained  a  specimen  (U.  S.  N.  M.,  No.  37238),  in  the  Caribbean  Sea  in 
1885.

Body  very  elongate,  with  a  few  large,  deciduous,  simple  scales  of  delicate  structure 
here  and  there  apon  its  surface. 

The  height  of  the  body  is  contained  9£  limes  in  its  length;  the  length  of  the  head  IA 
times.  Head  flattened  above,  concave  in  the  interorbital  region,  with  four  low  ridges,  the 
inner  pair  of  which  inclose  an  elongate,  diamond-shaped  space;  lower  jaw  longest. 

Eye  round,  lateral,  its  diameter  equal  to  one-fifth  of  the  length  of  the  head;  length  of 
the  snout  is  lij  times  the  diameter  of  the  eye;  opercle  with  two  obtuse  projections  behind, 
separated  by  a  notch. 

Spinous  dorsal  inserted  in  front  of  the  root  of  the  pectoral,  its  height  slightly  greater 
than  half  that  of  the  body;  its  length  less  than  halt  that  of  the  body;  placed  in  a  groove. 
supported  by  twenty-one  simple  slender  spines;  the  second  dorsal  is  placed  close  behind  the 
first,  not  SO  high  and  less  than  half  as  long,  with  nineteen  rays,  and  followed  by  two  tinlets. 

The  pectoral  origin  is  under  the  angle  of  the  opercle;  its  length  is  equal  to  that  of  the 
second  dorsal  fin.  The  spines  representing  the  ventrals  are  inserted  close  together  under 
the  hinder  part  of  the  roots  of  the  pectorals;  their  length  about  one-fourth  of  the  height  of 
the  body.  These  spines  are  longitudinally  grooved,  and  each  appears  to  consist  of  two  or 
three  spines  coalesced  together. 

Vent  very  slightly  posta  edian;  a  flat,  dagger-shaped  spine,  longitudinally  grooved, 
half  as  long  as  the  height  of  the  body,  inserted  close  behind  the  vent.  The  anal  fin  is 
inserted  behind  this  spine  at  a  distance  about  equal  to  its  length,  and  is  opposite  to,  but 
rather  shorter  than  the  second  dorsal.     Caudal  fin  deeply  furcate. 

The  lateral  line  descends  obliquely  from  above  the  opercle  to  the  middle  of  the  length 
of  the  fish,  and  then  continues  with  a  gentler  obliquity  along  the  posterior  part  of  the 
body  to  the  tail,  where  it  is  inserted  at  one-third  of  the  distance  from  the  ventral  to  the 
dorsal  outline. 

Radial  formula:  D.  xxt  |  10  |  n;  A.  IS  |  III;  P.  13;  V.  1. 

This  species  closely  resembles  Promethichthys  atlanticus,  from  which  it  may  be  dis- 
tinguished by  the  dagger-shaped  spine  in  front  of  the  anal  tin,  by  the  greater  number  of 
spines  in  the  first  dorsal — -1  instead  of  IS — by  the  smaller  number  in  the  second  dorsal — 
lit  instead  of  21 — and  by  the  longer  anal,  which  has  IS  instead  of  16  spines.  It  also  has 
the  ventral  spines  under  the  posterior  angle  of  the  pectorals,  instead  of  in  advance  of 
them,  and  has  iis  lateral  line  descending  more  gently. 

From  Xcsiiirchiis  it  is  distinguished  by  its  ventral  fins  and  by  the  absence  of  the  car- 
tilaginous prolongations  of  the  jaws. 

"This  fish,"  remarks  (lunther,  "was  known  front  a  single  example,  10  inches  long, 
obtained  at  Madeira  in  the  month  of  December,  and  has  been  fully  described  by  Johnson. 
The  Challenger  collection  contains  a  very  young  specimen,  only  33  millimeters  long,  which 
agrees  so  well  with  Johnson's  description  that  it  no  doubt  belongs  to  the  same  species.  ( )nly 
the  dagger-shaped  postanal  spine  is  shorter  than  the  ventral  spines,  and  also  the  separation 
of  distinct  Unlets  can  not  be  clearly  made  out,  as  might  be  expected  in  so  young  an  exam- 
ple. It  was  brought  up  in  the  dredge  at  Challenger  station  10.  in  lat.  34°  51'  X.,  Ion.  68 
30'  W.,  where  the  dredge  had  reached  a  depth  of  2,675  fathoms.  However,  no  part  of  the 
organization  of  these  Trichiuroids  indicates  that  they  descend  to  so  great  a  depth,  whilst. 
on  the  other  hand,  young  Trichiuroids  are  not  rarely  found  near  the  surface.  It  is,  there 
fore,  much  more  probable  that  this  small  lisli  entered  the  dredge  shortly  before  it  came  to 
the  surface.''     (Giuither.)

Color,  silver  gray,  the  spinous  dorsal  darker. 

This  fish,  the  "  Coelho  "  or  Eabbit  Fish  of  Madeira,  lives  habitually  at  the  bottom,  and 
is  taken  at  most  seasons  at  a  depth  of  from  100  to  300  or  400  fathoms,  and  in  the  summer 
months,  according  to  Lowe,  it  is  generally  one  of  the  commonest  and  cheapest  fishes  in  the 
market,  where  it  is  sold  in  bundles,  chiefly  to  the  Portuguese.  It  breeds  iu  August  and 
September,  and  attains  a  length  of  30  millimeters. 

Several  specimens  were  obtained  in  Bermuda  in  1S77  by  Dr.  Goode.  The  fishermen 
obtain  it  at  a  depth  of  60  to  100  fathoms,  and  it  is  known  to  them  as  the  "Catfish." 

DICROTUS,  Gunther. 
Dicrotus,  Gunther,  Cat.  Fish.  Brit.  Mus.  11,1860,  349.     (Type,  D.  armatus.) 

Body  rather  elongate,  compressed ;  cleft  of  the  mouth  wide.  The  first  dorsal  continuous, 
with  the  spines  of  moderate  strength,  and  extending  on  to  the  second;  finlets  none.  Ven- 
tral reduced  to  a  long,  crenulated  spine.  Preoperculum  with  several  spines  at  the  angle. 
Body  naked.  Several  strong  canines  in  the  jaws;  minute  teeth  on  the  vomer  and  the 
palatine  bones.    No  keel  on  the  tail.     Seven  branchiostegals.     Pseudobranchiie. 

The  fishes  assigned  to  this  genus  are  always  small.  They  will  perhaps  prove  to  be  the 
young  of  Prometheus  or  Gempylus.

15",  W.  Ion.  75°  33'  30"  off  Cape  Batteras.  The  first  two  were  obtained  in  excursions  off 
Newport,  R.  I.  The  example  from  station  2G01,  measuring  nearly  1  inch  in  length,  is 
referred  to  in  the  description,  the  other  two  not  being  at  the  present  time  accessible  to  us. 
We  are  led  to  refer  this  individual  to  the  genus  Dicrotus  because  of  the  absence  of  a  dagger- 
shaped  spine  behind  the  vent  and  because  of  the  similarity  in  the  number  of  dorsal  spines. 
we  assume  that  Dicrotus  of  Giinther  is  the  young  of  PromeihicMhys  atlanticus.  Our  spe- 
cies resembles  very  strongly  the  illustration  by  Dr.  Liitken,  in  "Spolia  Atlantica"  of  Nea- 
lotus  tripes,  and  as  there  is  no  indication  of  the  presence  of  a  dagger-shaped  spine  even  in 
an  example  of  nearly  1  inch  in  length  we  can  not  believe  that  our  individual  belongs  to  Xea- 
lotus;  it  possesses  the  characters  of  Dicrotus  much  more  nearly  and  we  shall  refer  to  it  under 
that  name.  The  length  of  the  individual  described  is  21  millimeters  to  the  base  of  the 
caudal.  The  greatest  height  of  the  body(3i  millimeters)  is  contained  6  times  in  the  standard 
length.  The  least  height  of  the  tail  is  one-half  the  length  of  the  eye.  The  length  of  the 
eye  is  one  half  the  length  of  the  postorbital  part  of  head  and  somewhat  more  than  one-sixth 
of  the  tot  al  length  of  the  head.  The  length  of  the  head  (9  millimeters)  is  contained  2J  times 
in  the  standard  length.  The  upper  jaw  reaches  to  the  vertical  from  the  front  of  the  orbit, 
and  the  lower  jaw  to  below  the  beginning  of  the  postorbital  third  of  the  orbit.  The  nostril  is 
placed  iu  front  of  the  eye  a  distance  equal  to  two-thirds  the  length  id' the  eye.  Three  large 
fangs  in  the  upper  jaw,  a  large  fang  uear  the  tip  of  the  lower  jaw,  and  8  smaller  teeth. 
Three  weak  diverging  spines  on  the  border  of  the  preoperculuin.  The  dorsal  originates  at  a 
distance  behind  the  eye  about  equal  to  one  and  one-half  times  the  length  of  the  eye,  or  about 
over  the  middle  of  the  operculum.  The  spines  are  all  serrated;  the  first  five  are  about 
equal,  their  length  nearly  equal  to  that  of  the  postorbital  part  of  the  head;  they  diminish 
gradually  in  size  from  the  fifth,  and  the  last  is  only  about  one-half  as  long  as  the  eye.  The 
longest  ray  is  scarcely  more  than  two-thirds  as  long  as  the  eye.  The  anal  origin  is  under 
that  of  the  soft  dorsal.  The  length  of  the  anal  base  is  about  one-half  that  of  the  snout. 
The  soft  dorsal  base  is  not  much  longer  thantheanal  base.  The  first  anal  spine  is  one-third 
as  long  as  the  eye;  the  second  spine  is  one-third  as  long  as  the  soft  dorsal  base.  The  long- 
est anal  ray  is  two  thirds  as  long  as  the  eye.  The  ventral  origin  is  under  the  sixth  spine 
of  the  dorsal;  the  spine  is  strongly  serrated;  its  length  equal  to  that  of  fhe.  ninth  dorsal 
spine,  slightly  more  than  one-eighth  of  the  standard  length.  The  ventral  contains,  also, 
either  a  single  bifid  rayor  two  simple  rays.  The  pectoral  origin  is  under  the  third  spine 
of  the  dorsal.  The  length  of  the  fin  is  one-fourth  the  length  of  the  head.  The  caudal  is 
moderately  forked;  the  middle  rays  one-half  as  long  as  the  snout  and  about  two  thirds  as 
long  as  the  external  rays.

The  greatest  height  equals  about  a  twelfth  of  the  extreme  length,  while  the  head  forms 
about  an  eighth  of  the  same.  The  head  is  oblong,  trenchant  above,  elevated  above  the 
eyes  for  a  space  considerably  greater  than  the  diameter  of  the  eye,  and  decurved  very 
obliquely  downwards  to  the  snout.  The  diameter  of  the  orbit  enters  about  G  times  in  the

Body  naked,  much  compressed,  attenuate,  tapering  gradually  from  vent  to  base  of 
caudal.  Caudal  peduncle  very  slender,  supporting  a  small  but  well  developed  caudal  fin. 
Vent  considerably  nearer  to  head  than  to  tail.  Lateral  line  simple,  in  a  deep,  wide  furrow, 
nearly  straight,  in  front  of  the  vent  gradually  ascending  to  the  scapular  region. 

Head  compressed,  its  upper  profile  nearly  horizontal;  snout  gibbous  near  its  end,  as  in 


DISCUSSION    OP    SPECIES    AND    THEIR   DISTRIBUTION'.  205 

Lepidopus.  Top  of  head  very  flat,  concave  between  the  eyes,  with  no  occipital  crest.  Inter- 
orbital  ridges  not  elevated.  Eyes  large,  slightly  postmedian.  Operculum  oblong,  reaching 
a  little  beyond  the  base  of  the  pectoral  tin.  Nostrils  horizontal,  in  front  of  the  eyes. 
Supramaxillary  uot  extending  to  vertical  from  front  of  eyes.  Lower  jaw  with  stout  cutane 
ous  appendage. 

Three  very  long,  simple,  compressed  teeth  on  each  intermaxillary  in  front;  outside  of 
these  a  few  minute  teeth,  and  behind  them  a  row  of  large  acicular  teeth.  In  lower  jaw  a 
single  row  of  moderately  large  acicular  teeth,  more  numerous  than  in  the  upper  jaw,  largest 
in  the  middle  of  the  jaw.     Palatine  teeth  minute. 

Dorsal  fin,  beginning  above  the  operculum,  nearly  uniform  in  height  throughout  its 
entire  length,  and  continuous  almost  to  the  caudal.  Rays  very  numerous  (over  150  in  /.'. 
ekmgatus).  Anal  beginning  near  the  vent,  preceded  by  a  single  scale  like  appendage; 
spines  very  numerous  (numbering  with  the  rays  about  100  in  B.  <jlt>n</afus,  all  except  28  or  30 
being  spines),  minute  and  almost  hidden;  a  short  fin  posteriorly. 

Caudal  small,  normal,  forked.     Pectoral  inserted  almost   horizontally,  with  lower  rays 
longest,  and  its  upper  outline  rounded.     Ventral  tins  represented  each  by  a  minute  scale 
like  spine,  inserted  below  the  origin  of  the  pectorals. 

Pseudobranchiae  present;  gills  1,  a  slit  behind  the  fourth.  Gill-rakers  short  and  spiny, 
in  a  single  series  on  the  first  and  second  arches,  almost  obsolete  on  the  third  and  fourth. 
(In  Lepidopus  caudatus  all  the  arches  are  supplied  with  several  series  of  rakers.) 

Benthodesmus  may  be  distinguished  from  Lepidopus  and  Evoxymetopon  by  the  following 
salient  characters: 

1.  The  slenderer,  lower  form  of  the  body,  the  height  of  which  in  B.  elongatus  at  the 
vent  is  one-fourth  the  length  of  the  head;  in  Lepidopus  caudatus,  nearly  half  the  length  of 
the  head. 

2.  In  the  location  of  the  vent,  which  is  considerably  nearer  to  the  head. 

3.  In  the  depressed  form  of  the  head,  its  fiat  profile,  the  insignificance  of  the  frontal 
ridges,  and  the  absence  of  the  occipital  crest. 

4.  In  the  much  greater  number  of  dorsal  rays. 

5.  In  the  more  advanced  position  of  the  rudimentary  ventrals,  which  are  situated  in 
Benthodesmus  under  the  base  of  the  pectorals. 

0.  In  the  ineseuce  of  a  single  small  postanal  scute,  in  place  of  the  two  larger  ones  in 
]j<pid(>i>us. 

10.  In  the  characteristic  arrangement  of  the  gill-rakers.

bert, Bull,  xvi,  U.  S.  Nat.  Mus.,  1883,  910.— Jordan,  Cat.  Fish.  N.  A.,  1885,  G7. 

Body  attenuate,  its  height  at  the  vent  contained  four  times  in  length  of  head,  its  width 
being  about  one-third  of  its  height  at  the  point  mentioned.  Length  of  caudal  peduncle 
half  of  greatest  height  of  body.     Least  height  of  tail  one  third  width  of  interorbital  area. 

Length  of  head  contained  seven  and  a  half  times  in  length  of  body,  its  greatest  width 
one-sixth  of  its  length;  its  greatest  height  nearly  one  fourth  of  its  length;  width  of  interor- 
bital area  (on  the  bone)  one  fourth  of  the  height  of  the  head.  Length  of  snout  contained 
2i  times  in  length  of  head.  Upper  jaw  not  reaching  to  vertical  from  anterior  margin  of 
eye.  and  equal  in  length  to  the  postorbital  portion  of  head.  Lower  jaw  in  length  equal  to 
about  twice  the  greatest  height  of  body.  Mandibular  tip  nearly  one-third  as  long  as  the 
diameter  of  the  eye.  Eye  slightly  postmedian  in  location,  the  orbital  diameter  equal  to  half 
the  length  of  the  snout. 

Besides  the  three  long  teeth,  there  are  on  each  intermaxillary  8  or  9  of  moderate  size; 
on  one  side  many  small  intermediate  teeth  are  present.  The  number  of  teeth  in  the  lower 
jaw  varies  from  13  on  the  one  side  to  21  on  the  other. 

The  first  branchial  arch  has  13  gill  rakers,  the  longest  of  which  measures  about  2  milli- 
meters.   The  second  arch  has  about  the  same  number,  while  on  the  third  there  are  but  6  or

7,  very  small,  and  present  only  in  the  angles,  while  in  the  fourth  there  are  about  the  same 
number,  very  inconspicuous. 

The  dorsal  fin  originates  above  the  middle  of  the  operculum,  and  at  a  distance  from  the 
snout  equal  to  twice  the  length  of  the  snout. 

The  anal  tin  is  composed  of  about  100  spines  and  rays.  Owing  to  the  mutilation  of  the 
specimen  it  is  impossible  to  determine  how  many  there  are  of  each,  but  there  are  supposed 
to  be  about  28  rays,  normally  united  by  a  membrane  into  a  fin. 

The  caudal  is  also  imperfect,  but  the  middle  rays  are  seen  to  be  about  half  as  lung  as 
the  remnants  of  the  external  rays.  The  flu  is  supposed  to  resemble  in  shape  that  of  Lepi- 
dopus <■(<  tela  tits. 

The  pectoral  originates  under  the  tip  of  the  opercular  flap.  Its  outline  is  rounded 
above  instead  of  emarginate,  as  in  Lepidopus  eaudatus.  Its  longest  ray  equals  in  length 
the  postorbital  part  of  the  head. 

The  ventrals  originate  at  a  distance  from  the  snout  equal  to  that  of  the  base  of  the 
pectorals  from  the  same  point.  They  are  rudimentary  and  represented  by  minute  scutes, 
the  length  of  which  is  3J  millimeters  in  the  specimen  before  us,  and  about  equal  to  half  the 
interorbital  width.

Csecal  appendages  8,  in  the  specimen  examined.  Some,  however,  may  have  been  lost,

it  was  found. 

Color,  uniform  silvery,  with  traces  of  dark  color  upon  head  and  tail. 

The  type  of  this  description,  a  remarkable  fish,  taken  from  the  stomach  of  a  halibut 
caughton  the  western  edge  of  the  Grand  Bank  of  Newfoundland  in  80  fathoms,  was  received 
in  1887  from  Oapt.  Eoderick  Morrison,  of  the  Gloucester  fishing  schooner  Laura  Nelson.

Ar;nl.,  Lisb.,  vol.  I,  tab.  iv,  fig.  1. 

This  species  lias  never  been  described,  except  in  so  far  as  its  characters  are  included 

in  that  of  the  genus.    Lowe's  original  statement  concerning  it  was  as  follows: 

Of  this  most  curious  new  genus  a  single  individual  only  has  yet  occurred.  The  whole 
fish  is  of  a  dark  coffee  color,  approaching  to  black  ('uniform  black,' says  (iiinther),  and  has 
in  form  so  close  a  general  resemblance  to  Lepidopus  argyreus,  that  it  might  well  be  taken 
hastily  for  a  mere  variety  of  that  lish. 

It  has  been  obtained  only  from  Madeira  aud  the  coast  of  Portugal,  where  specimens  4 
or  5  feet  long  have,  in  rare  instances,  as  stated  by  Capello,  been  caught  on  the  long  lines 
used  by  the  fishenneu  for  the  capture  of  deep-sea  sharks. 

■•  We  have  no  information,"  writes  Giinther,  "  as  to  the  exact  depth  at  which  this  lish 
lives,  but  there  is  no  doubt  that  it  belongs  to  the  deep-sea  fauna.  The  large  eye,  the  black 
color  of  the  body,  and  the  thinness  of  the  bones  of  the  head  and  of  the  vertebne,  are  ad- 
ditional evidence  of  the  bathybial  habits  of  the  fish."

Jphanojms  minor,  Collett,  Vidensk.  Selsk.  Forhandl.  C'hristiania,  1886,  No.  19,  3. 

A  single  specimen  of  a  silvery-gray  species  of  Aphtmoptts  was  taken  July  4,  1886,  off 
the  east  coast  of  Greenland,  lat.  6.3°  N.,  Ion.  31°  W.,  by  Captain  Pedersen,  of  Sandefjord, 
Norway,  who  placed  it  in  the  University  Museum  at  Christiania. 

The  following  is  Collett's  diagnosis: 

Dark  silvery  or  steel- colored.  The  length  of  the  head  is  about  2%  in  the  length  of  the 
body  to  the  vent;  diameter  of  the  eye  about  4t  in  the  length  of  the  head;  8  long  teeth  in 
the  intermaxillary,  the  two  foremost  "canines"  the  longest;  8  teeth  in  the  lower  jaw,  a  trifle 
shorter;  no  teeth  in  vomer  and  the  palatine  bones.  Ventrals,  none;  a  strong  dagger- 
shaped  spine  behind  the  vent.    Air  bladder  present;  appendices  pylorica?.,  7. 

Length  from  tip  of  snout  to  the  vent  (in  the  single  specimen  examined)  352  millimeters.

1  The  following  is  Lowe's  diagnosis,  as  published  in  1839:  "Form  as  in  Lepidopus,  elongate,  much  com- 
pressed, like  a  sword  blade,  naked,  but  with  a  short  keel  on  each  side  toward  the  tail.  Muzzle  and  teeth 
as  in  Lepidopus  (Gouan),  but  the  palatines  unarmed.  Dorsal  lins  2,  nearly  equal.  Anal  lin  as  in  Lepi- 
dopus (but  w  ith  a  strong,  sharp  spine  instead  of  a  scale  before  it),  a  little  behind  the  vent.  No  trace  or  rudi- 
ment of  ventral  tins."

This  is  a  well-known  form,  frequently  found  in  shoal  waters  from  Cape  Cod  to  the 
West  Indies,  and  needs  no  description  here. 

The  Challenger  obtained  the  scabbard-fish  off  Inosima,  Japan,  at  a  depth  of  345  fath- 
oms. Young  were  obtained  by  the  U.  S.  Fish  Commission  at  station  2273,  at  17  fathoms; 
2289,  at  7  fathoms;  2121-2,  at  31-31  fathoms. 

A  commercial  fishery  of  considerable  importance  exists  at  Jamaica.  This  species 
enters  the  estuary  of  the  St.  Johns  River  iu  Florida,  and  has  been  known  to  leap  into  row- 
boats.  Linnaeus  wrote  of  it  in  1758:  Totus  argenteus  exiliens  ex  aqua  saj>c  in  cymbani.

Body  elongate,  covered  with  small,  cycloid  scales.  Cleft  of  the  mouth  >blique,  the 
lower  jaw  projecting.  Gardiform  teeth  on  jaws  and  vomer  and  palatines;  a  patch  ofvilliform 
teeth  on  the  tongue.  Skull-crest  much  more  elevated  in  adult  than  in  young.  Dorsal 
many  rayed,  low,  extending  from  nape  nearly  to  base  of  caudal;  anal  similar,  but  shorter; 
both  without  distinct  spines;  pectorals  small;  ventrals  well  developed,  thoracic,  I,  5,  partly 
received  into  a  groove  in  the  abdomen;  caudal  fin  widely  forked. 

Liitken  has  reviewed  in  his  Spolia  Atlantica  the  species  of  the  genus  Coryphwna,  and  an 
abstract  of  his  conclusions  is  here  preseuted: 

The  genus  Coryphcena,  the  "Dolphins"  as  they  are  called  by  sailors,  is  one  of  those 
peculiarly  pelagic  in  its  characteristics,  and  it  is  an  example,  more  remarkable  than  any 
other,  of  the  extreme  confusion  which  has  resulted  from  the  fact  that  a  numbe.  of  really 
limited  existing  species  has  been  divided  into  a  great  number  of  nominal  species,  based 
only  upon  differences  of  age  and  sex,  individual  peculiarities,  different  geographical  locali- 
ties, carelessly  made  drawings,  incomplete  descriptions,  etc.,  a  confusion  which  has  been 
wrongly  charged  to  Cuvier.  The  mistake  of  separating  the  species  into  two  genera,  Cory- 
phcena and  Lampugus,  has  already  been  rectified  by  competent  authority,  and  the  number 
of  species  believed  to  be  well  founded  at  the  same  time  was  reduced  from  19  to  G.  lie  is  now 
of  the  opinion  that  the  number  should  not  be  more  than  2,  or  at  the  most  3.  The  two  time- 
honored  species  of  Linnaeus,  the  large  Dolphin,  "La  Petite  Dorrade"  (ft  hippurus),  which 
reaches  a  length  of  nearly  6  feet;  and  the  little  Dolphin,  "La  Petite  Dorrade"  {G.  equisetis), 
which  rarely  exceeds  2£  feet.  In  Spolia  Atlantica,  Liitken  gives  an  extensive  comparison 
of  these  two  species,  having  special  reference  to  the  changes  which  they  undergo  with  age, 
and  those  which,  like  the  length  of  ft  equisetis,  are  sexual ;  and  these  variations  have  been  illus- 
trated by  figures  of  the  head,  which  are  reproduced  in  this  work.  Most  of  the  species  de- 
scribed and  figured  can,  according  to  Liitken,  be  very  easily  assigned  to  the  two  cosmopoli- 
tan species  referred  to,  which  have  been  often  brought  in  by  sailors,  the  only  ones,  in  fact, 
from  which  he  has  been  able  to  get  material  for  study.  Liitken  hesitates  in  his  opinion 
concerning  G.pelagiea  (azorica,  sicula)  of  the  Mediterranean,  which  has  been  accepted  by 
most  authors  who  have  studied  the  Mediterranean  fauna,  but  which  very  probably  does 
not  differ  specifically  from  ft  hippurus;  at  least,  he  felt  obliged  to  regard  as  a  young  speci- 
men of  this  species  a  little  "  ft  pelayicw"  from  the  Mediterranean,  which,  under  that  name, 
was  sent  to  him  for  examination  by  a  museum  in  Italy.  In  support  of  his  opinion  that 
there  are  really  only  two  species  of  Coryphwna,  he  mentions  two  circumstances — one,  that 
Giinther,  although  he  formally  acknowledges  more,  actually  refers  all  the  specimens  in  his 
own  custody  to  these  two  species  arid  has  not  recognized  any  others;  and  again,  that  Liit- 
ken himself  has  been  able  without  difficulty  to  divide  numerous  specimens  of  young  Cory- 
phcena, from  18  to  02  millimeters  long,  caught  by  Scandinavian  fishermen,  into  two  series, 
representing  two  species,  and  to  refer  these  series  to  the  two  species  before  mentioned,  and 
to  no  others,  to  wit,  most  of  them  to  ft  equisetis,  and  a  fewer  number  to  ft  hippurus.  The 
little  Coryphcena*  are  so  dissimilar  to  the  adults  that  it  is  very  easy  that  they  should  have 
given  rise  to  mistake,  and  thus  it  has  happened  that  the  young  ft  hippurus  has  been  de- 
scribed by  Pallas  under  the  name  of  C.  faseiolata.  Liitken,  in  the  work  referred  to,  ui\cs 
comparative  descriptions  of  the  young  individuals  of  both  species  in  their  successive  states 
ami  in  relation  to  their  adult  forms,  and  gives  figures  illustrative  of  his  ideas,  calling  at 
teution  to  the  fact  that  the  greater  length  of  the  ventrals  in  ft  hippurus,  and  their  point  of

origin  under  the  pectorals  less  farther  backward  than  in  C.  equisetis,  is  one  of  the  best  means 
of  separating  the  young  of  the  two  forms,  and  corresponds  also  to  one  of  the  best  distinc- 
tive characters  of  the  adult.  The  small  individuals  of  both  species  uot  only  have  the 
preoperculuni  provided  with  spines,  but  also  a  scapular  spine  and  supraorbital  spine  on 
each  side.  The  larger  specimens  have  the  body  very  elongate,  but  are  at  the  same  time 
less  thick,  without  being  compressed,  as  they  are  in  advanced  age.  The  dorsal  is  rela- 
tively as  low  as  in  C.  equisetis:  in  the  adult,  its  origin  at  a  point  scarcely  behind  the  anterior 
margin  of  the  eye;  in  the  young,  above  the  posterior  margin  of  the  preoperculuni j  in  those 
still  younger,  between  the  preoperculuni  aud  the  opening  of  the  gills;  in  ('.  hippurus,  adult, 
above  the  posterior  margin  of  the  pupil;  in  the  younger  specimens  of  the  same  species, 
above  the  branchial  opening,  and  so  ou.  The  system  of  coloration  is  a  marked  character 
in  the  different  ages.

A  very  elaborate  study  of  Brama  has  been  completed  by  Liitken,  based  upon  a  large 
series,  chiefly  of  young  specimens.  Concerning  B.  Bait  he  concludes  thatit  is  quite  cosmo- 
politan in  its  distribution,  occurring  from  the  Faroe  Islands  to  the  Capo  of  Good  Hope, 
and  is  represented  by  closely  similar,  if  not  identical,  forms  on  the  coast  of  Chili  (B. 
chilensis  and  australis)  and  New  Zealand  (B.  squamosa)  and  in  the  waters'  of  Japan.  He 
states  that  it  has  not  yet  been  found  in  the  West  Indies  or  off  the  east  coast  of  North 
America,  overlooking,  perhaps,  the  fact  that  Brama  Bali  was  observed  at  the  Bermudas  in 
1880  by  Dr.  Goode.  He  considers  B.  orcini  and  B.  Dussumicri  and  Taractcs  asper  to  be  im- 
mature forms  and  gives  a  very  doubtful  acceptance  to  six  species,  claiming  to  be  distinct 
from  B.  Rati,  described  from  various  parts  of  the  Atlantic: 

Brama  Agassizii,  Poey  (Mem.  Hist.  Nat.  Cuba,  II,  1856-8,  201).    Cuba. 

Brama  Brevoorti,  Poey  (loc.  cit,  20G).    Cuba. 

Brama  Saussurii,  Lunel  (Revision,  etc.,  185,  pi.  n).    Cuba. 

Brama  longipinnis,  Lowe  (Proc.  Zool.  Soc,  1843,  82).    Madeira. 

Brama  princcps,  Johnson  (Proc.  Zool.  Soc,  1863,  38,  pi.  vn).    Madeira. 

Brama  Baschi  Esmark  (Forh.  Vid.  Selsk.,  Christiania,  1861).     Fiumark,  Iceland. 

Serious  discussion  of  these  forms  can  not  well  be  attempted  without  a  large  series  of 
specimens  of  all  ages.  In  the  meantime,  it  is  most  convenient  to  consider  all  the  Atlantic 
forms  as  members  of  a  single  species,  quite  variable  in  the  proportions  of  the  body  and  the 
fins. 

B.  japonica,  Hilgendorf,  has  the  snout  more  convex  than  B.  Baii,  shorter  vertical  fins, 
and  smaller  paired  fins,  and  the  lesser  size  of  the  scales  in  the  axils  of  the  pectorals.

Gyrinomene,  Vaillant  (name  only),  Exp.  Sci.  Travailleni  et  Talisman,  1887,  355,  18. 

Body  much  compressed,  short  and  elevated,  covered  with  small,  coarsely  spinous  scales, 
on  which  no  lateral  line  can  be  traced;  abdomen  prominent  and  keeled.  Mouth  wide,  ob- 
liquely ascending,  with  projecting  lower  jaw.  The  jaws  are  armed  with  a  very  narrow 
baud  (which,  posteriorly,  becomes  a  single  series)  of  small  line  teeth  of  unequal  size.  The 
vomer  and  palatine  bones  are  toothless.  The  maxillaries  terminate  at  their  upper  and  in- 
ner extremity  in  a  pair  of  short  pointed  processes,  which  form  peculiar  fang-like  projections 
in  the  inside  of  the  mouth  in  front  of  the  vomer.  Bones  of  the  head  thin,  with  wide,  mucif- 
erous  cavities,  the  lower  limb  of  the  preoperculum  denticulated.  Eyes  very  large.  Dor- 
sal long,  without  spinous  division;  anal  similar  in  form  and  composition;  interradial  mem- 
brane very  fragile.  Pectorals  large;  ventral  fins  thoracic,  with  more  than  5  rays  (f).

The  specimen  from  Madeira,  described  in  detail  and  well  figured  by  Johnson,  was  the 
only  one  known  until  the  French  expedition  obtained  another  off  the  coasts  of  Morocco  in 
1,105  meters.    Johnson  ascribed  to  it,  although  with  doubt,  10  ventral  rays,  but  the  rays

are  much  confused,  broken,  and  split  down  to  the  base,  and  it  is  fortunate  that  Vaillant 
has  been  able  to  make  out  the  true  ray  formula  to  be  1, 5.  The  spine  is  enlarged  into  a  thin 
scalpel-shaped  lamella  and  marked  with  numerous  oblique  stria?. 

Giinther  concluded,  from  the  structure  of  the  cranial  bones,  the  immense  eyes,  the 
black  color  of  the  cavity  of  the  mouth  and  pharynx,  and  also  from  the  extreme  scarcity  of 
the  fish,  that  this  species  belongs  to  the  deep-sea  fauna,  and  subsequent  explorations  proved 
the  wisdom  of  his  prophecy. 

Eadial  formula:  D.  27;  A.  22-25;  P.  18;  V.  I,  5. 

Giinther  remarks  concerning  D.  aureus,  Campbell: 

I  should  be  inclined  to  refer  this  fish,  which  is  known  from  four  specimens,  2J  inches 
long,  cast  up  on  Hokitika  beach  (New  Zealand),  to  the  same  species  as  the  Madeiran  speci 
men,  but  for  the  seeming  absence  of  the  enlarged  ventral  spine.  This,  of  coarse,  might  be 
also  accounted  for  by  the  less  advanced  age  of  the  specimens.  All  the  other  differences  as 
they  appear  in  the  description  would  probably  disappear  on  a  direct  comparison  of  the  ex- 
amples. The  perforations  of  the  interradial  membrane  of  the  dorsal  and  anal  fins,  which 
Campbell  regards  as  an  extraordinary  character,  may  also  be  seen  in  the  Madeiran  type,  and 
are  due  to  the  extremely  delicate  structure  of  the  membrane.  The  radial  formula  is  D.  20; 
A.  21;  P.  17.

Body  compressed,  oblong,  covered  with  moderate-sized  scales.  Snout  obtuse  convex, 
compressed.  Cleft  of  mouth  wide,  oblique.  Eye  large.  Dorsal  very  elongate,  much  ele- 
vated, extending  from  the  forehead  to  the  caudal,  composed  of  filiform  spines,  unarticu- 
lated,  triangular  in  form ;  anal  similar  in  form  and  structure;  ventrals  jugular,  of  4-6  slender 
rays.    Pseudobranchite  present.     Air-bladder  very  small. 

This  is  a  pelagic  form,  widely  distributed,  and  but  sparsely  represented  in  museums. 
The  characters  by  which  the  four  recognized  species  are  separated  are  not  of  the  greatest 
diagnostic  importance. 

Pteraclis  papilio,  Lowe,  was  described  in  1813  (Proc.  Zool.  Soc,  1843,  p.  83),  from 
Madeira.  It  has  41  rays  in  the  dorsal,  and  35  in  the  anal.  Lowe  believed  that  the  last  six 
rays  of  the  dorsal  were  detached  from  the  rest. 

Pteraclis  oeellattts,  C.  &  V.  (Hist.  Nat.  Poiss.,  IX,  p.  363,  pi.  cclxxi)  was  described 
from  Mozambique  material.     It  has  a  few  more  rays  in  the  vertical  fius  (D.  45;  A.  42). 

Pteraclis  carolinus,  ('.  &  V.,  was  described  from  a  mutilated  specimen,  4  inches  long, 
from  the  coast  of  South  Carolina. 

Pteraclis  velifer,  the  Coryphcena  velifera  of  Pallas,  came  from  the  Indian  Ocean.  Liitken 
has  seen  fit  to  identify  with'it  several  young  individuals  7  to  15  millimeters  long,  taken  with 
dredge  by  Andrea  and  Joersen  in  the  Atlantic,  lat.  21°  29'  N.,  long.  28°  36'  W.  (Spolia 
Atlantica,  502  and  600,  pi.  iv,  fig.  B). 

The  single  specimen  obtained  by  the  Albatross  agrees  sufficiently  well  with  the  descrip- 
tion of  P.  carolinus  and  is  assigned  to  that  species  for  the  present.

Scombroids,  with  body  compressed  and  more  or  less  elevated,  covered  with  small  or 
minute  cycloid  scales.  Profile  anteriorly  blnnl  and  rounded.  Mouth  small.  Premaxillaries 
protractile  or  not.    Dentition  feeble;  no  teeth  on  vomer  or  palatines;  oesophagus  armed 

with  numerous  horny,  barbed,  or  hooked  teeth.  Gills  4,  a  slit  behind  the  fourth,  (oil

Pseudobranchise  present.  Cheeks  scaly.  Preopercle  entire  or  serrate.  Lateral  line  well 
developed.  Dorsal  fin  single,  long,  with  the  spines  few  or  weak,  often  obsolete;  anal  fin 
Long,  similar  to  the  soft  dorsal,  usually  with  3  small  spines,  which  are  often  depressible 
in  a  fold  of  skin;  ventrals  thoracic  or  jugular,  normally  I,  5,  but  sometimes  reduced  or 
altogether  wanting;  caudal  fin  lunate  or  forked.  Usually  no  air  bladder.  Pyloric  caeca 
commonly  numerous.    Vertebras  more  than  10+14. 

The  members  of  this  family  are,  as  a  rule,  surface-dwellers.  Among  them  is  the  Rud- 
der fish  or  Log  fish,  Deirusperciformis,  common  everywhere  in  summer,  lurking  under  float- 
ing spars  ami  drift  wood,  and  often  swimming  under  the  keels  of  vessels.  The  liar  vest  fish, 
Stromateus  triacantluis,  is  also  found  near  the  surface,  swimming  under  large  Medus;e. 
Apolectus  is  probably  the  young  of  Stromateus  and  Hoplocoryph  is  pn  »bably  that  of  Schedophi- 
lus.  In  all  warm  seas  the  young  of  the  various  species  of  this  family  are  sure  to  occur  iu 
the  pelagic  surface  fauna.

Stromateids,  with  elongate  body  covered  with  minute  scales.  Lateral  line  arched  an- 
teriorly. Mouth  moderate  or  small.  Teeth  small,  in  jaws  only.  Vomer,  palatines  and 
tongue  toothless.  Epibranchial  bone  of  fourth  arch  with  long  toothless  processes.  Dorsal 
long,  continuous,  without  spinous  division.  Anal  with  the  tlm  anterior  rays  uubranched, 
resembling  feeble  spines.  Ventrals  thoracic,  moderate.  Pectorals  moderate.  Caudal 
furcate.    Bones  of  vertical  fins  scaly.    Air  bladder  small.     Pyloric  appendages,  nine  or  ten. 

This  genus  is  represented  by  two  species  recorded  from  the  Atlantic.  C.  pompilus  (Lac.) 
C. and  V.,  is  not  very  unusual  in  the  vicinity  of  Nice,  though  rare  elsewhere  in  the  Medi- 
terranean, and  has  occasionally  been  taken  in  the  Atlantic  as  far  north  as  the  British  Isles 
and  south  to  Gibraltar  and  Madeira.  G.  britannicus,  Giiuther,  is  known  from  a  single  speci- 
men cast  ashore  on  the  coast  of  Cornwall  in  1859.  Both  forms  are  well  figured  by  Day, 
pi.  xl.  The  "Blackfishes"  undoubtedly  swim  at  times  near  the  surface,  but  there  is 
ground  for  supposing  that  they  live  also  at  considerable  depths,  especially  C.  britannicus. 

There  are  other  species  catalogued  by  the  Italian  and  French  ichthyologists  under  the 
name  Gentrolophus,  but  none  of  them  appear  to  be  other  than  surface-swimming  forms. 
They  are  all  exceedingly  rare  and  not  well  understood.

The  Blackfish  occurs  in  the  Mediterranean  and  along  the  coasts  of  Europe  from  Spain 
to  Yorkshire  and  Northumberland.     Lowe  observed  it  about  Madeira. 

A  specimen,  9  inches  long,  was  taken  off  Dennis,  Mass.,  Nov.  23,  L888,  by  the  U.  S. 
Fish  Commission. 

This  form  is  pelagic,  like  the  pilot  fishes,  and  is  believed  to  be  able  to  descend  to  con- 
siderable depths.

Body  compressed,  oblong,  covered  with  minute  scales;  cleft  of  the  month  of  moderate 
width,  with  the  jaws  equal;  eye  moderate;  preopercular  margin  spiny.  One  dorsal,  com- 
mencing behind  the  nape  of  the  neck,  formed  by  flexible  spines  and  branched  rays,  extend 
ing  nearly  along  the  whole,  back;  anal  similar  to  the  dorsal,  but  much  shorter.  Ventrals 
thoracic  (subjugular  in  Sch.  maculatus),  formed  byl  spine  and  5  rays.  A  series  of  small 
teeth  in  the  jaws;  palate  smooth.     Branchiostegals  7.     Pseudobranchiae. 

The  species  of  this  genus  are  pelagic;  young  examples,  at  least,  are  frequently  captured 
in  the  surface  net  in  the  open  ocean.  Some  of  the  species,  however,  possess  structural  char- 
acters which  indicate  bathybial  habits;  for  instance,  a  singular  want  of  firmness  of  the  tis- 
sues, especially  of  the  bones.     {Gunther.)

The  body  is  strongly  compressed,  of  an  elongate,  ovoid  shape,  its  depth  being  con- 
tained 2|  times  in  the  total  length,  fins  not  included.  The  head  is  small,  as  deep  as 
long,  and  less  than  one-fourth  of  the  total  length  (without  caudal).  Interorbital  space  con- 
vex, broader  than  the  diameter  of  the  eye,  which  is  situated  immediately  below  the  upper 
profile  of  the  head,  nearly  as  long  as  the  snout,  and  one  fourth  the  length  of  the  head. 
Snout  obtuse,  with  projecting  lower  jaw  and  oblique  mouth.  Mouth  of  moderate  width,  the 
cleft  extending  to  below  the  front  margin  of  the  eye.  Maxillary  rather  narrow,  but 
widening  toward  its  extremity.  Teeth  minute,  implanted  in  a  single  series  on  the  sharp 
edge  of  the  jaws.    The  palate  is  toothless. 

The  preopercular  margin  is  armed  with  short  spines,  which  usually  become  a  little 
longeron  the  posterior  margin;  these  longer  spines  have  an  oblique  dorsal  direction.  Also 
the  interoperculum  is  spinous,  the  suboperculum  less  so.  Operculum  membranous;  its 
upper  portion  shows  radiating  osseous  strhe,  which  project  beyond  the  margin. 

The  gill  rakers  of  the  outer  branchial  arch  are  long,  narrow,  and  rather  widely  set. 
Gill  openings  very  wide. 


DISCUSSION    OF    SPECIES    AND    THEIR   DISTRIBUTION.  215 

Tlii'  dorsal  fin  commences  above  the  rout  of  the  pectoral  ami  terminates  at  a  short  dis 
tance  from  the  caudal,  the  caudal  peduncle  being  about  as  deep  as  long.  This  tin  is  rather 
low,  the  longest  rays,  behind  the  middle  of  the  tin.  being  noi  erectile  into  a  vertical  posit  ion. 
The  caudal  fin  (slightly  injured)  has  a  rounded  margin,  and  is  r  ither  shorter  than  the  head. 

The  pectoral  fin  has  a  broad  base,  is  more  than  half  as  long  as  the  head,  and  has  the 
upper  rays  longer  than  the  lower.  Ventrals  rather  small,  close  together,  and  inserted  in 
advance  of  the  pectorals. 

The  entire  fish  is  covered  with  minute,  cycloid  scales;  on  the  head  they  appear  to  be 
present  on  the  cheek  only.  The  upper  pari  of  the  head  is  covered  with  a  thick,  spongj 
skin,  as  in  Centrolophus, 

Radial  formula:  D.  38-50;   A.  25-29. 

The  colors  of  a  fresh  fish  are  a  pale  greenish  olive,  marbled  with  darker,  the  markings 
being  in  the  form  of  spots  on  the  upper,  and  of  irregular  longitudinal  bands  on  the  lower 
half  of  the  body.  Also  the  vertical  fins  are  spotted  with  blackish.  The  iris  is  nearly  white, 
and  a  ring  of  small  white  pores  encircles  the  orbit. 

The  specimen  described  is  \)h  inches  long  and  in  good  condition,  with  the  exception  of 
the  lower  part  of  the  abdomen,  which  is  lacerated  and  shrunk  in  consequence  of  the  loss 
of  the  intestines.  All  parts  of  the  body  are  in  that  state  of  softness  which  is  peculiar  to 
many  deep-sea  fishes.     (Giiittlicr.) 

Adult  specimens  have,  according  to  Giinther,  been  obtained  in  the  Mediterranean,  one 
on  the  coast  of  Ireland,  and  another  in  the  South  Sea,  near  Samoa. 

This  is  primarily  a  pelagic  surface  form,  but  it  seems  very  possible  that  it  inhabits  the 
middle  or  lower  strata  of  the  ocean  as  well.  Dr.  Giinther  says  that  it  is  evident  that  at 
least  in  the  adult  state  it  descends  to  some  depths.  The  want  of  firmness  in  the  tissues 
seems  to  clearly  indicate  it  as  a  deep-sea  fish.  He  hazards  the  opinion  that  the  depth  to 
which  it  may  descend,  probably  does  not  exceed  10(1  fathoms.  ( "ailing  attention  to  the  fact 
that  the  young  of  the  species  are  much  more  frequently  found  near  the  surface  than  the 
adult,  he  mentions  the  habit  of  this  and  similar  forms  id'  congregating  around  the  floating 
Medusae,  and  also  questions  the  accuracy  of  the  theory  that  fish  ever  feed  upon  .Medusa', 
since  he  says  the  fish  could  draw  but  little  nourishment  from  these  animals.  As  a  matter 
of  fact,  many  of  our  surface  oceanic  fishes  feed  voraciously  upon  various  forms  of  Medusae 
and  upon  Sulpn.  We  have  often  taken  large  quantities  of  this  kind  of  food  from  the  stomachs 
of  various  surface  Scombroids,  as  well  as  from  Alutera  and  Mold. 

I  )r.  Giinther's  full  description,  which  is  quoted  above,  is  taken  from  a  specimen  obtained 
at  Port  Rush,  County  Antrim,  Ireland,  in  August,  187S,  captured  in  a  salmon  net.  Mr. 
Ogilby,  who  sent  it  to  the  British  Museum,  was  very  much  impressed  by  the  softness  of  the 
flesh.  "It  was."  lie  says,  "the  most  delicate  adult  fish  1  ever  handled;  so  much  so,  that 
within  twenty  four  hours  after  its  capture  the  skin  of  the  belly  and  the  intestines  fell  off 
when  it  was  lifted,  and  it  felt  in  the  hand  quite  soft  and  boneless."  This  is  quoted  to  em- 
phasize what  has  been  said  regarding  the  softness  of  its  tissues,  and  its  similarity  in  this 
respect  to  the  fishes  inhabiting  the  abyss.

Body  oblong,  much  compressed  throughout,  the  head  thicker  than  any  part  of  the  body. 
Dorsal  outline  rising  rapidly  to  the  origin  of  the  dorsal  fin,  thence  more  regularly  curved; 
the  region  at  the  base  of  the  dorsal  and  anal  strongly  compressed  ;  caudal  peduncle  slender, 
widened  at  the  base  of  the  fin.  Mouth  large,  horizontal;  maxillary  narrow,  reaching  to 
beyond  middle  of  eye.  Teeth  in  jaws  in  one  row,  slender,  sharp,  closely  and  regularly  set, 
those  in  the  lower  jart  largest;  no  teeth  on  vomer,  palatines,  or  pharyngeals.  Gill-rakers

with  small  spinules;  a  series  along  each  ray,  dividing  as  the  ray  branches;  dorsal  fin  com- 
mencing above  the  axil  of  the  pectoral,  composed  of  50  to  CO  rays,  which  are  all  soft  and 
flexible,  some  of  the  anterior  unbranched;  the  fin  low  in  front,  increasing  in  height  behind; 
none  of  the  rays  more  than  once  forked;  anal  shorter  than  the  dorsal,  similar  to  it,  of  35  to  40 
rays;  some  of  the  anterior  apparently  undivided;  caudal  fin  elongate,  fan-shaped,  the 
middle  rays  produced ;  accessory  rays  numerous,  procnrrent;  pectorals  with  a  fleshy  base, 
fan  shaped,  the  middle  rays  longest;  ventrals  thoracic,  inserted  just  behind  the  pectorals, 
narrow,  consisting  of  1  short  subspinous  ray  and  4  long  soft  rays.  Air  bladder  large.  Ver- 
tebra} numerous,  the  vertebral  column  extremely  flexible  and  soft.  Cranial  bones  tolerably 
firm;  bones  of  the  face  and  opercles  very  flexible.  The  entire  body  is  characterized  by  a 
want  of  firmness,  as  it.  can  be  doubled  up  as  readily  as  a  piece  of  soft,  thick  rag.  {Jordan 
and.  Gilbert.) 

This  genus  is  represented  by  a  single  species.  I.  enigmaticus,  Lockington  (Schedophilus 
enigmatieus,  Giinther,  Challenger  Report,  xxn,  40,  PI.  xliv).  The  exact  source  of  the  types  is 
not  known.  They  were  bought  in  the  San  Francisco  market  in  1878,  and  the  fishmongers 
said  that  they  were  deep-sea  fish.  Lockington  reports  a  small  specimen  in  the  museum  of 
the  University  of  California,  found  off  the  coast  of  Washington.  The  fact  that  they  have 
not  since  been  seen  shows  how  unusual  they  are,  and  proves  that  they  live  at  great  depths 
— if  any  proof  other  than  their  remarkable  structure  were  required.  Steiudachner  also 
had  a  specimen.

Body  scaleless,  with  the  exception  of  the  lateral  line.  Dorsal  and  anal  fins  long,  the  former 
beginning  on  the  nape.  Branchiostegals  6;  pseudobranchiffl  present.  The  fin  rays  thickly 
covered  with  sharp,  nettle-like  spines,  visible  to  the  naked  eye. 

The  type  of  this  genus  is  Schedophilopsis  spinosus,  Steiudachner  (loc.  cit.),  obtained 
by  him  at  considerable  depths  off  the  coast  of  California,  near  San  Francisco.  The  National 
Museum  possesses  a  specimen  (Cat.  No.  37327)  obtained  by  Dr.  August  C.  Kinney,  at  Astoria, 
Oregon.

Body  elongate,  not  elevated,  not  compressed  at  the  bases  of  the  vertical  fins.  Head 
moderate.  Byes  lateral.  Mouth  terminal,  little  oblique,  with  small  sharp  teeth  in  one

covered  with  small  cycloid  scales.  Lateral  liue  continuous,  unarmed.  Bases  of  fins  with- 
out spinules;  dorsal  and  anal  lius  long  aud  low,  composed  of  soft  rays  only;  pectoral  fins 
moderate,  their  bases  fleshy,  as  in  Icosteus;  ventral  tins  small,  thoracic,  I,  5.  Pyloric  caeca 
about  0,  large.     Bones  all  very  flexible,  cartilaginous.    (Jordan  it  Gilbert.) 

Represented  by  a  single  specimen  obtained  at  the  same  time  and  under  the  same  cir- 
cnmstances  as  Icosteus  enigmaticus.  This  was  described  by  Jordan  &  Gilbert  under  the 
name  Icichthys  Lockingtonii.  Dr.  Giinther's  catalogues  it  under  Schedophilus  (Challenger

ACROTUS,  Bean. 
Aerotus,  Bean,  Proc.  U.  S.  Nat.  Mns.  1887,631. 

Shape  of  body  as  in  Tcosteus,  from  which  it  differs  in  the  absence  of  ventrals  and 
spiny  tubercles  along  (lie  lateral  line,  and  in  having  an  emarginate  caudal. 

Head  short;  mouth  moderate;  eye  small.  Teetb  minute,  uniserial,  on  intermaxillary 
and  mandible;  vomer,  palate,  and  pharynx  toothless.  Gill  openings  wide,  the  membrane 
not  attached  to  the  isthmus.  Gills  4,  a  wide  slit  behind  the  fourth,  (iill  rakers  short,  soft. 
and  flexible.  Pseudobranchia'  well  developed.  Branehiostegals  6.  Vent  somewhat  in

ACROTUS  WILLOUGHBYI,  Bean.    (Figure  225.) 
Arrotus  Willoughoyi,  Bean,  loc.  cit. 

The  greatest  height  of  the  body  at  the  vent  is  contained  3^  times  in  the  total  without 
the  caudal.  The  caudal  peduncle  is  very  slender;  its  least  beigbt  little  more  than  one-third 
of  its  length  and  not  much  exceeding  one-fourth  the  length  of  the  bead.  The  length  of  the 
head  is  about  one-sixth  of  the  total  without  caudal.  The  snout  forms  one-fourth,  the  eye 
one-twelfth,  and  the  interorbital  width  one-third  the  length  of  the  bead.  The  maxilla 
reaches  to  below  the  middle  of  the  eye.  The  upper  jaw  is  one-third  as  long  as  the  head. 
Gill  rakers  15,  of  which  9  are  below  the  angle;  the  longest  about  as  long  as  the  eye. 

The  origin  of  the  dorsal  has  not  been  clearly  made  out;  the  first  ray  that  can  be  seen 
without  dissection  is  nearly  midway  between  the  eye  and  the  end  of  the  dorsal,  but  dissec- 
tion reveals  7  rays  in  advance  of  this.  The  dorsal  begins  much  nearer  the  bead  in  Icostt  us, 
and  dissection  may  show  that  rays  are  developed  much  farther  in  advance  than  we  have 
been  able  to  distinguish  them.  Forty-one  rays  have  been  counted  in  the  dorsal,  the  longest 
of  them  little  exceeding  one-third  length  of  head.  The  caudal  peduncle  is  as  long  as  the 
bead  without  the  snout.  The  caudal  is  large,  emarginate;  its  middle  rays  four-sevenths  as 
long  as  the  external  rays  and  two  thirds  as  long  as  the  bead. 

The  vent  is  at  a  distance  from  the  tip  of  the  snout  equal  to  3  times,  and  from  the  base 
of  the  caudal  a  space  equal  to  3J  times  the  length  of  the  head.  The  first  evident  anal  ray  is 
at  a  distance  behind  the  vent  equal  to  one-sixth  length  of  head.  The  anal  has  38  rays,  the 
longest  a  little  less  than  one-third  as  long  as  the  head. 

The  pectoral  is  placed  close  to  the  head  and  nearly  in  the  middle  of  the  height;  its 
length  is  two-thirds  the  length  of  the  head;  it  has  20  rays. 

The  lateral  line  has  a  slight  curve  over  the  pectoral  and  becomes  median  about  half  way 
between  the  pectoral  and  the  vent.     Skin  naked.     Peritoneum  very  dark. 

Color  chocolate  brown;  inside  of  mouth  and  gill  openings  rich,  dark  brown. 

The  type  of  the  species  (catalogue  number  39340)  is  o'.'ii  inches  long.  The  viscera  are 
wanting.  The  specimen  was  obtained  at  Damon,  Wash.,  July  9,  1887,  by  Charles  Wil- 
loughby. 

The  following  extracts  from  Mr.  Willoughby's  letter  contain  additional  information 
about  the  species:. 

A  few  days  ago  I  discovered  a  fish  lying  on  this  beach  different  from  any  that  I  have 
ever  seen  before.  It  seemed  to  be  perfectly  fresh  aud  as  if  it  had  not  been  on  shore  more 
than  an  hour.  The  color  of  the  skin  seemed  to  have  been  nearly  all  removed  by  washing 
about  on  the  sand.  The  [pectoral]  fin  and  tail  had  been  partly  destroyed.  The  fish  was 
G  feet  long.  The  flesh  of  the  fish  is  very  white,  fine  grained,  aud  fat.  The  fish  in  color 
and  fatness  resembles  the  black  cod.  Anoplopoma  fimbria.  The  bones  are  extremely  soft, 
so  much  so  that  the  fish  can  not  bear  a  weight  of  5  pounds  pulling  on  it  without  severing 
the  head.  The  fish  was  a  female,  with  a  large  roe  well  matured.  None  of  the  oldest  Indians 
of  the  agency  have  ever  seeu  anything  like  it.

The  fish  was  preserved  in  brine,  and  has  now  become  so  fragile  that  it  must  be  given 
to  the  osteologist  to  be  prepared  as  a  skeleton.  Mr.  Lucas  has  found  in  front  of  the  rayed 
portion  of  the  dorsal  fin  numerous  groups  of  cartilaginous  plates  representing  iuterneurals, 
but  no  rays  can  be  found  supported  by  them.  He  counted  70  vertebras  and  observed  what 
appear  to  be  rudiments  of  a  pelvis,  but  no  traces  of  ventral  fins.

Graminicolepids  with  body  deep,  compressed,  large  eye,  small  mouth,  head  and  oper- 
cula  partly  rugose ;  teeth  minute,  and  absent  from  the  palatines.  Pectoral  short  and  rounded. 
Dorsal,  anal,  and  pectoral  branched. 

GRAMMICOLEPIS  BRACHIUSCULUS,  Poky  (Figure  221). 
Grammicolipis  bruchiuaculus,  Poey,  loc.cit. — Shufeldt,  loc.  tit. 

The  length  of  this  extraordinary  fish  is  470  millimeters.  The  head  enters  five  times 
into  the  total  length  of  the  body,  and  2jj  times  into  its  greatest  depth.  The  body  is  much 
compressed,  and  quite  deep.  The  very  large  eye  is  contained  2^  times  in  the  length  of  the 
head,  and  lacks  the  membrana  adiposa. 

The  branchial  apertures  are  deeply  cleft,  but  I  fail  to  find  more  than  four  branchiostegal 
rays,  without  being  able  to  assert  that  there  may  not  be  a  greater  number  of  them.  The 
snout  is  short.  The  prefrontal,  the  turbinal,  and  the  anterior  suborbital  are  extremely  hard, 
and  covered  with  spiny  rugosities.  The  preoperculum  and  iuteroperculum  have  rugose 
borders,  while  the  remaining  opercular  bones  are  entirely  so.  The  mouth  is  small,  sub- 
vertically  cleft;  the  premaxillary  process  is  huge,  and  is  lodged  in  a  fossa  of  the  cranium. 
The  maxillary  is  complicated.  The  teeth  are  simply  a  narrow  row  of  minute  prickles;  they 
do  not  occur  upon  the  vomer  nor  the  palatines. 

The  leading  spine  of  the  first  dorsal  series  is  rugose,  as  is  the  first  ventral,  the  two 
posl  anals,  and  the  external  ones  of  the  tail,  which  latter  show  the  condition  equally  well  in 
either  one. 

The  rays  of  the  pectoral,  second  dorsal,  and  the  anal  tins  are  compressed,  and  do  not 
ramify  at  their  extremities.  The  pectorals  are  very  short  and  rounded.  On  the  other 
hand,  the  vertical  fins,  the  dorsal,  and  anal  are  well  developed. 

The  tail  was  injured  and  apparently  cut;  the  membrane  which  unites  its  rays  had  dis- 
appeared; the  peduncle  which  supports  it  is  large,  and  capable  of  communicating  a  power- 
ful impulse  to  the  act  of  progression.  The  thoracic  ventrals  unquestionably  possess  a 
rugose  spine  and  0  flexible  ones  that  are  branched. 

Aside  from  the  frontal  bones  and  the  suborbitals  where  the  skin  abruptly  terminates, 
and  the  nasal  portion  of  the  snout,  all  the  trunk  and  the  head  is  covered  with  scales,  includ- 
ing the  inferior  mandible. 

The  scales  in  no  way  resemble  those  found  among  the  acanthopterygian  fishes.  Their 
length  greatly  exceeds  their  width;  they  have  the  appearance  of  parchment — transparent, 
brittle  when  dry — overlap  each  other,  and  are  strengthened  longitudinally  by  a  raised 
lineal  ridge. 

Their  contact  with  each  other  is  so  extremely  intimate  that  it  lends  to  the  skin  of 
either  side  a  very  smooth  appearance — so  much  so,  that  the  rough  borders  of  the  scales 
would  not  be  suspected  without  the  aid  of  the  fingers. 


DISCUSSION   OF   SPECIES   AND   THEIR   DISTRIBUTION.  219 

Thanks  to  the  length  of  these  scales,  four,  five,  or  six  of  them  arc  sufficient  to  span  the 
height  of  the  trunk,  one  of  such  a  series  being  crossed  by  the  lateral  line,  where  itspres- 
ence  is  denoted  by  a  raised  ridge. 

The  leading  scales  on  the  body,  above  as  well  as  below,  arc  shorter,  and  where  carried 
(in  to  the  head  are  doubly  as  linn  as  those  found  at  the  fin  rays. 

Without  having  done  more  than  counted  the  scales  in  a  longitudinal  line,  I  calculate 
that  the  number  is  considerably  above  200;  those  of  the  head,  although  shorter,  have  the 
same  form  as  those  of  the  trunk.     There  are  no  scales  upon  the  tins. 

'flie  caudal  peduncle  develops  neither  a  cartilaginous  nor  an  osseous  plate  at  its  sides. 
Posterior  to  the  anus  the  ventral  keel  is  rough. 

The  cranium  is  more  cartilaginous  in  structure  than  it  is  osseous,  except  the  frontals, 
which  are  rugose  in  line  in  the  supraorbital  region,  and  bristly  in  front,  as  are  the  turbinate 
and  suborbitals;  these  latter  are  four  in  number,  the  last  three  being  very  slender.  There 
are  two  supratemporals. 

The  inferior  mandible  is  characterized  by  several  rows  of  minute  spines  upon  the  den- 
tary  and  articular  elements.    The  vertebrae  number  10  plus  30. 

The  anterior  neural  spine  is  not  excavated,  being  lofty  and  smooth ;  the  five  that  follow 
aii'  short  and  inclined  backwards.  The  remaining  ones  are  slender,  which  applies  also  to 
i  heir  heemapophyses.    The  last  vertebra  is  without  lateral  spines. 

The  pleurapoplryses  are  inconspicuous,  feebly  developed,  and  have  much  the  same  size 
and  shape,  as  the  epipleurals.  I  discover  but  one  pseudo-interneural  spine  in  front  of  the 
one  that  supports  the  first  dorsal  fin  ray.     (Shufeldt.)

A  single  specimen  of  this  remarkable  fish  was  obtained  by  Poey,  at  Cuba,  in  1872. 

An  elaborate  anatomical  study  has  been  made  by  Dr.  Shufeldt.

A  family  of  telencephalons  fishes  related  to  the  mackerels.  The  body  is  oblong,  enm- 
[tressed,  and  covered  with  cycloid  scales;  the  lateral  line  continuous  and  unarmed;  the 
head  compressed;  the  opercula  unarmed;  the  nostrils  double;  the  mouth  with  a  lateral 
cleft,  upper  jaw  scarcely  protractile;  teeth  small  and  conical,  on  the  palateas  well  as  jaws; 
branchial  apertures  extensive;  branchiostegal  rays  5  or  <i;  dorsal  more  or  less  divided, 
and  with  the  spinous  portion  shorter  than  the  soft.  The  skeleton  has  numerous  vertebra} 
(in  Womem  16+25);  the  stomach  very  numerous  pyloric  appendages. 

This  family  has  been  constituted  for  the  reception  of  several  genera,  at  one  time  referred 
to  the  Scombridae,  viz,  \'<>ui<iis,  Gasteroschisma,  Gubiceps,  Seriolella  and  Platystethus.  The 
species  arc  all  marine,  and  found  in  tropical  or  warm  temperate  seas.  The  last  two  are 
represented  only  in  the  Australian  and  Polynesian  waters.

Nomeus  Gronovii  is  one  of  the  most  widely  distributed  and  abundant  of  all  pelagic 
fishes,  occurring  as  it  does  in  the  Tropical  Atlantic  and  in  the  Indian  Ocean.  It  has 
been  found  as  far  north  as  the  Bermudas  (Goode).  It  abounds  in  the  Sargasso  Sea  and 
under  Physalia.  Ten  individuals  were  taken  in  a  dip  net,  from  the  deck  of  the  Albatross, 
off  the  Florida  coast,  all  swimming  under  one  Portuguese  man-of-war. 

The  large  fan-shaped  veutrals  are  used  as  support  in  resting  on  the  bottom,  and  in 
swimming  they  are  generally  closed  in  their  groove  unless  the  fish  is  moving  leisurely, 
when  they  may  be  partly  expanded.

The  young  forms  <>t'  this  genus  appear  to  have  been  found  chiefly  in  East  Indian  and 
Australian  seas  and  in  the  Pacific,  the  adult  tonus  in  the  Atlantic  and  Mediterranean. 
Liitken,  in  his  Spolia  Atlantica,  critically  reviews  the  group  in  his  usual  masterly  style.

Psenes petliu-ultt*,  LTtkkn,  Spolia  Atlantica,  1880,  516  (108),  fig. ;  601  (193). 

A  species  of  Psenes  with  a  high,  short,  compressed  body,  nearly  colorless  and  semi- 
transparent,  taken  at  the  Strait  of  Surabaja,  is  recognized  by  Liitken  as  distinct. 

Greatest  height  of  the  body  (23  millimeters)  contained  2J  times  in  the  total  length 
(without  caudal);  the  length  of  the  head  (13  millimeters)  is  one-quarter  of  the  total  length. 
Diameter  of  the  eye,  5  millimeters;  length  of  the  snout,  3A  millimeters.  The  pectoral  tins  are 
9  millimeters  long;  ventrals  14  millimeters,  extending  considerably  beyond  the  end  of  the 
pectorals.  The  vertical  fins  are  quite  high  (10  millimeters),  and  show  a  tendency  to  become 
falcate  posteriorly.  Dorsal  fin  with  1-  spines  and  34  rays;  anal  with  3  spines  and  34  rays. 
Caudal  fin  furcate.  Lateral  line  placed  high.  Scales  small.  Dentition  as  in  the  other 
species  of  the  genus;  teeth  in  the  maxillary  are  finer  and  farther  apart  than  in  the  mandi- 
ble; the  end  of  the  maxillary  reaches  to  the  vertical  from  the  anterior  margin  of  the  pupil.

A  single  specimen  was  obtained  by  the  Albatross  in  32°  24'  N.  lat.,  76°  55'  30"  W.  Ion., 
at  a  depth  of  528  fathoms. 

Liitken  also  describes  another  species  of  Psenes  from  the  Atlantic,  which  he  thinks 
may  possibly  be  distinct — Psenes  maculatus,  Sx>olia  Atlantica,  p.  110  (518).  A  specimen, 
seemingly  of  this  species,  was  obtained  by  the  Albatross  in  the  western  Atlantic,  N.  lat. 
27°  49',  W.  Ion.  76°  12',  over  a  depth  of  033  fathoms.  The  specimen  was  taken  at  the  sur-

This  fish  was  originally  described  from  a  specimen  5  feet  long  seen  by  Eafinesque  at 
Solanto,  Sicily,  June  15,  1808.  It  has  since  been  observed  at  Nice,  in  the  Adriatic  and 
at  Malta  and  Elba,  and  at  Cette,  whence  came  the  beautiful  specimen  which  we  have  seen  in 
the  Museo  Civico  of  Genoa. 

Prof.  Giglioli  was  the  first  to  point  out  the  interesting  series  of  metamorphoses  by 
which  Astrodermus  and  Diana  develop  into  Ausonia  and  Luvarus. 

Lowe  observed  both  young  and  old  at  Madeira,  and  Steindachner  found  it  on  the  coast 
of  Spain.  Two  were  thrown  ashore  on  the  Cornish  coast  in  18G6,  and  from  one  of  these, 
45  inches  long,  Day  had  made  the  excellent  figure  for  his  ''Fishes  of  Great  Britain  and 
Ireland."

Longest  dorsal  ray  shorter  than  pectorals,  which  are  nearly  as  long  as  the  head.  Anal 
very  low  in  front,  a  little  higher  behind.     Head,  3^;  depth,  If. 

Radial  formula:  D.  54;  A.  40;  V.  14-17;  Vert,  23+22;  L.  3-4  feet. 

Color,  a  rich  brocade  of  silver  and  lilac,  rosy  on  the  belly;  everywhere  with  round 
silvery  spots;  head,  opercles,  and  back  with  ultramarine  tints,  jaws  and  fins  vermillion; 
flesh  red. 

This  form,  exceedingly  rare  in  the  Mediterranean,  has  occasionally  during  the  last  century 
been  found  along  the  coasts  of  Europe  as  far  north  as  Norway,  also  about  Madeira  and 
Iceland;  it  hail  been  reported  from  off  Newfoundland,  Nova  Scotia  (?),  and  Maine;  no 
specimen  from  the  Atlantic  had  been  in  the  possession  of  any  American  museum,  when  a 
specimen  was  taken  by  schooner  Mildred  V.  Lee,  Capt.  William  T.  Lee,  off  Le  Have  ridges, 
between  62°  and  03"  Ion.  \V.,  42°  and  49°  lat.  N. 

A  specimen  from  Japan  in  the  U.  S.  National  Museum  is  apparently  of  the  same 
species.  We  are  not  aware  that  this  has  hitherto  been  recorded  from  the  Pacific.  There 
is  every  reason  to  believe  that  the  fish  is  at  times  an  inhabitant  of  considerable  depths.

CYTTUS,  Gunther. 
Cyttus,  GUNTHER,  Cat.  Fish.  Brit.  Mus.,  n,  1860,  p.  396. 

Body  compressed  and  elevated,  covered  with  very  small  scales;  mouth  protractile. 
Two  contiguous  dorsal  fins,  the  first  with  eight  or  nine  spines,  the  anal  with  two  short 
spines.  No  bony  plates  along  the  base  of  the  dorsal  and  anal  fins.  Ventral  fins  composed 
of  oue  spine  and  six  or  eight  soft  rays.  Minute  teeth  in  the  jaws  aud  on  the  vomer,  none 
on  the  palatine  bones.     Branchiostegals,  eight. 

The  type  is  Cyttus  australis  (Capros  australis,  Kichardson),  from  Australian  seas.  C. 
abbreviates,  Hector  (Gunther,  Challenger  Report,  xxn,  p.  22,  PI.  x,  fig.  B),  was  obtained 
in  400  fathoms  some  200  miles  off  Cape  Farewell,  New  Zealand.  ('.  hololepis,  described 
below,  was  obtained  in  220  fathoms.  It  is  fair  to  assume  then,  since  two  out  of  three 
of  the  known  species  are  found  in  deep  waters,  that  G.  australis  also  descends  to  the 
depths. 

CYTTUS  HOLOLEPIS,  Goodf,  and  Bean,  n.  s.     (Figures  233,  233a,  2336.) 

The  greatest  depth  of  the  body,  which  is  at  the  ventral  origin,  is  two-fifths  of  the  total 
without  caudal.  The  length  of  the  head  is  three-eighths  of  the  standard  length.  The  eye 
is  very  large, equal  to  two  ninths  of  the  length  without  caudal,  and  more  than  one-half  the 
length  of  the  head.  The  width  of  the  interorbital  space,  9  millimeters,  is  two-fifths  of  the 
length  of  the  bead.  The  intermaxillary  is  protractile  and  when  drawn  out  a  deep  horseshoc-

shaped  groove  is  exposed  between  the  orbits.  The  length  of  the  intermaxilla  (8  millime- 
ters) is  one-half  that  of  the  head  without  the  snout.  The  maxilla  is  thin,  broad,  obtuse  at 
the  extremity;  its  length  (!)  millimeters)  equal  to  that  of  the  interorbital  area.  The  length 
of  the  mandible  (10  millimeters)  is  nearly  one-half  that  of  the  head.  The  mouth  is  almost 
vertical  when  closed.  The  quadrate  bone  ends  posteriorly  in  a  broad,  obtuse  spine;  it  has 
several  ridges  with  minute  cirri.  The  supraorbital,  also,  has  several  minutely  ciliated 
ridges. 

Teeth  in  the  jaws  so  minute  as  to  be  indistinguishable  except  to  the  touch.  The  nostrils 
are  placed  close  to  tlie  front  of  the  eye  and  somewhat  above  its  middle;  the  posterior  is 
much  the  larger;  it  is  a  spear-shaped  slit  about  three  times  as  long  as  the  anterior. 

Pseudobranehipe  well  developed;  14  or  15  very  small  lanceolate  gill-rakers  below  the 
angle  on  the  first  arch.  The  gill-openings  are  very  wide,  the  membranes  very  deeply  cleft 
and  only  narrowly  attached  to  the  isthmus  in  front.     Branchiostegals  8. 

The  dorsal  ami  ventral  origius  are  in  the  same  vertical. 

The  distance  of  the  spinous  dorsal  from  the  snout  is  equal  to  the  greatest  height  of  the 
body.  The  spinous  dorsal  contains  0  or  7  spines,  the  first  of  which  is  minute,  about  one- 
fourth  as  long  as  the  second,  which  is  as  long  as  the  eye.  The  second  spine  is  finely  ser- 
rated in  the  middle  of  its  anterior  margin  and  is  dilated  at  the  root  so  as  to  partly  conceal 
the  base  of  the  third  spine. 

The  rays  of  the  soft  dorsal  increase  in  size  backwards,  the  first  being  only  one-third  as 
long  as  the  last,  which  is  about  one-fourth  as  long  as  the  head.  The  longest  rays  of  the 
soft  dorsal  are  about  the  nineteenth  to  the  twenty -fourth;  these  are  slightly  longer  than  the 
last.  The  caudal  is  almost  truncate  or  very  slightly  rounded  when  expanded.  Its  middle 
rays  are  nearly  as  long  as  the  eye. 

The  vent  is  under  the  fifth  ray  of  the  second  dorsal,  and  the  anal  origin  under  the  sixth 
ray.  The  anal  rays,  also,  increase  in  size  backwards  but  the  longest  are  not  more  than 
three-fourths  as  long  as  those  of  the  dorsal.  The  rays  of  the  soft  dorsal  and  anal  are  all 
simple  and  articulated.  The  length  of  the  ventral  spine  is  one-fourth  of  the  standard 
length;  it  exceeds  that  of  the  longest  ventral  ray.  The  ventral  when  fully  expanded  is  sub- 
triangular;  the  spine  is  minutely  serrated  on  its  anterior  margin.  The  pectoral  is  sub-cir- 
cular when  expanded  and  is  composed  entirely  of  simple  articulated  rays,  the  longest,  in 
the  middle  of  the  fin,  one-half  as  long  as  the  eye.  There  are  about  10  rows  of  scales  between 
the  lateral  line  and  the  base  of  the  spinous  dorsal,  and  about  07  in  the  lateral  line. 

Radial  formula:  D.  Vi-vn,  2G;  A.  23;  V.  I,  6;  P.  10. 

The  types  of  the  description  are  a  single  individual,  No.  39296,  taken  by  the  Albatross 
at  station  2358,  N.  hit,  20°  19',  W.  Ion.  87°  03'  30",  in  220  fathoms,  off  Yucatan,  and  two

fathoms,  Little  Bahama  Bank. 

The  species  is  a  true  Cyttus,  resembling  the  southern  species,  but  with  a  single  preanal 
spine,  fewer  rays  in  the  vertical  tins,  and  with  the  body  entirely  scaled.  The  plates  at  the 
dorsal  and  anal  bases  are  well  developed. 

No.  3929G  is  75  millimeters  long,  and  the  larger  specimen  of  No.  39297  is  86  millimeters 
long,  while  the  length  of  the  smaller  is  80  millimeters.

Scales  present  only  in  the  lateral  line  and  its  immediate  neighborhood.  Three  or  four  bony 
plates  between  the  ventrals  and  the  vent,  the  anterior  ones  armed  with  very  strong  spines, 
pointing  backward.  At  the  base  of  the  dorsal  and  anal  tins  a  series  of  little  nodules,  cone 
sponding  to  the  interspinous  spaces. 

Dorsal  occupying  a  large  part  of  the  length  of  the  back,  its  spines  very  robust;  the 
third,  the  strongest,  is  in  length  equal  to  one-third  the  height  of  the  body;  the  first  eight 
or  ten  soft  rays  increase  in  size,  the  first  being  the  lowest;  they  are  farther  apart  than 
those  which  follow  them  and  are  united  by  a  membrane  only  at  their  base.  Anal  very 
similar  to  the  soft  portion  of  the  dorsal;  the  first  spine  stout  and  immovable.  The  caudal 
peduncle  is  widened  at  its  extremity  and  the  caudal  is  abruptly  truncate.  Pectorals  moder- 
ate, obtuse,  composed  of  13  rays.  Ventrals  remarkably  long,  inserted  nearly  in  the  verti- 
cal from  the  insertion  of  the  pectorals,  and  extending  behind  the  anal  spine:  the  two 
branches  which  form  each  ray  are  very  distinct,  even  from  the  base,  as  in  Trigla  and  similar 
fishes. 

Radial  formula:  D.  vin,  27;  A.  I,  25;  V.  i,  7;  Br.  vn. 

Scales  iu  lateral  line  53,  in  transverse  line  9-40. 

Color  silvery,  passing  into  roseate  above  and  below.  Fins  yellowish:  the  ventrals 
have  the  membrane  black  and  the  rays  milky  white. 

This  species  was  originally  described  by  Lowe  from  Madeira,  and  his  specimen,  eleven 
inches  in  length,  now  in  the  British  Museum,  is  believed  to  be  the  type.  The  Travaillenr

which  are  on  the  back. 

Radial  formula:  D.  v,  29;  A.  26;  V.  1,5. 

This  remarkable  form  is  known  only  from  a  single  specimen,  obtained  by  Peron,  the 
French  navigator,  in  "  the  Atlantic  Ocean."  It  was  probably  taken  in  the  surface  net.  The 
type  is  16  lines  in  length.  A  full  description  is  given  by  Cuvier  and  Valenciennes,  who 
refer  to  it  as  a  little  fish,  whose  height  is  equal  to  its  length;  covered  with  great  cones,  so 
rugged  and  bold  that  a  drawing  of  it  resembles  a  map  of  a  volcanic  country. 
Its  affinities  are  believed  by  some  ichthyologists  to  be  Berycoid.

A  Capros  with  upper  and  lower  profiles  of  the  snout  concave,  with  small  scales,  with 
strong  spines  in  the  dorsal  and  ventral  litis.  Adults  usually  brownish  red;  young,  some

The  Boarfish  of  English  authors  is  said  to  be  common  in  the  .Mediterranean,  and  has 
also  been  found  in  the  waters  of  Madeira;  stragglers  have  a  few  times  been  taken  on  the 
south  coast  of  England  and  Ireland;  the  French  explorers  found  it  at  various  depths  from 
30  to  175  fathoms  in  the  Gulf  of  Gascogne,  on  the  coast  ot  Morocco,  Soudan,  and  Spain, 
and  on  the  Banc  D'Arguin.  It  is  one  of  those  forms  which,  while  more  especially  charac- 
teristic of  the  shore  fauna,  descends  into  moderately  deep  waters  adjacent,  and  is  by 
courtesy  admitted  to  the  deep-sea  lists,  especially  since  the  other  members  of  the  same 
family  are  characteristic  deep-water  forms,  and,  in  the  opinion  of  Dr.  Gunther,  but  rarely 
come  to  the  surface.

Radial  formula:  D.  xv-xxi,  1, 11-13;  A.  10-12;  L.  lat.  US/20. 

This  form  was  originally  described  from  Nice.  Risso  says  that  it  lives  at  great  depths, 
approaching  the  coast  only  in  August  at  the  time  of  spawning,  and  that  its  natation  is 
slow  and  feeble.  It  has  since  been  found  off  Toulon  and  Marseilles,  and  by  Lowe  near 
Madeira,  where  it  was  taken  swimming  at  the  surface.  Lowe  is  also  of  the  opinion  that  it 
occurs  at  very  great  depths.  Its  flesh  when  eaten  is  a  violent  poison,  as  was  demonstrated 
by  the  personal  experience  of  Risso  himself.  A  single  specimen  was  obtained  by  the  U.  S. 
Fish  Commission  at  Wood's  Holl,  Massachusetts,  November  10,  1890  (Cat  .No.  41436,  U.  S.

The  fish  described  in  1810  by  Eisso  was  said  to  be  so  rare  that  during  thirty  years 
previous  only  two  specimens  had  been  taken.  "This  rarity,''  says  Eisso,  "is  due  to  the 
fact  that  it  never  leaves  those  cold  submarine  valleys  where  our  fishermen  can  only  set 
their  long  lines  in  the  month  of  August,  so  that  they  are  never  taken  except  by  chance." 


DISCUSSION   OF   SPECIES   AND   THEIR    DISTRIBUTION.  L>33 

•'Its  chief  characteristics,"  he  continues, "are  its  globular  eyes  of  extraordinary  dimen- 
sions, its  large  and  strong  fins,  the  powers  of  rapid  swimming,  and  a  generally  vigorous 
and  active  constitution.  All  these  characteristics  arc  necessary  for  its  defense  against  the 
oceanic  animals  which  frequent  the  marine  abysses  in  which  it  customarily  lives." 

Jt  has  since  been  taken  about  Nice.  Genoa,  and  Naples,  and  also  at  .Messina.  Canes- 
trini  says  that  it  spawns  in  the  spring. 

EPIGOXUS  OCCIDENTALS,  GOODE  and  BEAN,  a.  s.     (Figure  236.) 

The  greatest  height  of  the  body  at  the  ventrals  (17  millimeters  in  the  type  specimen)  is 
contained  a  little  oxer  seven  times  in  the  length  without  caudal.  The  least  height  of  the 
tail  (7  millimeters)  equals  the  width  of  the  interorbital  space  measured  on  the  bone.  The 
length  of  the  head  (39  millimeters)  is  nearly  one-third  of  the  total  without  caudal.  The 
greatest  width  of  the  head  (20  millimeters)  is  about  one  half  its  length.  The  long  diame- 
ter of  the  eye  (17  millimeters)  is  contained  seven  times  in  the  standard  length  and  is  nearly 
one  half  the  length  of  the  head.  The  length  of  the  snout  (9  millimeters)  is  about  one-halt 
that  of  the  eye.  The  maxilla  reaches  somewhat  beyond  the  anterior  margin  of  the  orbit; 
its  length  (1 1  millimeters)  equals  one-half  the  length  of  the  head  without  the  snout.  The 
intennaxilla  is  slant  and  thin,  its  length  (9  millimeters)  about  equal  to  that  of  the  snout; 
its  connection  with  the  tip  of  the  maxilla  is  ligamentous.  The  mandible  reaches  nearly  to 
below  the  middle  of  the  eye:  its  length  (18  millimeters)  about  equal  to  that  of  the  eye. 
The  posterior  nostril  is  very  slightly  in  advance  of  the  front  of  the  eye;  the  anterior  nostril 
is  a  little  nearer  to  the  eye  than  to  the  tip  of  the  snout.  Both  pairs  of  nostrils  arc  superior 
rather  than  lateral.  The  groove  for  the  intermaxillary  process  is  naked,  narrow;  its  length 
(5  millimeters)  equal  to  twice  its  width.  A  weak  spine  on  the  operculum.  The  pseudo- 
branchiae  are  well  developed.  Sixteen  gill-rakers  below  the  angle;  the  longest  (5  milli- 
meters) about  one-third  the  length  of  the  maxilla.  Weak  villiform  teeth  in  very  narrow 
bands  on  the  intermaxilliary  and  mandible.     Vomer  and  palatines  toothless. 

The  dorsal  begins  over  the  eighth  row  of  scales;  its  first  spine  is  minute;  its  length 
only  about  one-eighth  the  length  of  the  second  spine,  which  is  nearly  as  long  as  the  base  of 
the  fin;  the  third  spine  is  a  little  longer  than  the  second  and  fourth,  and  the  last  is  two- 
thirds  as  long  as  the  fourth.  The  interspace  between  the  dorsals  is  as  long  as  the  last 
spine.  The  base  of  the  soft  dorsal  is  one  third  as  long  as  the  head;  the  longest  ray  is 
slightly  longer  than  the  base  of  the  fin.  The  distance  from  the  soft  dorsal  to  the  beginning 
of  the  caudal  is  about  twice  the  greatest  height  of  the  body.  The  caudal  is  imperfect;  the 
middle  rays  appear  to  be  about  two  thirds  as  long  as  the  outer  and  a  little  more  than  oue- 
t  hi)  d  as  long  as  the  head.  The  anal  originates  under  the  seventh  ray  of  the  soft  dorsal  and 
under  the  twenty-ninth  scale  of  the  lateral  Line;  the  length  of  its  base  equals  one-third  of 
its  distance  from  the  caudal;  its  first  spine  is  very  short,  scarcely  one-third  as  long  as  the 
second,  the  length  of  which  (7  millimeters)  is  one-half  that  of  the  maxilla.  The  longest  ray 
is  as  long  as  the  base  of  the  soft  dorsal.  The  vent  is  under  the  twenty-third  scale  of  the 
lateral  line  and  under  the  interspace  between  the  spinous  and  soft  dorsals.  The  ventral 
origin  is  behind  that  of  the  pectoral  and  in  advance  of  the  spinous  dorsal  origin;  it  is  also 
under  the  sixth  scale  of  the  lateral  line.  The  spine  is  a  little  more  than  one-half  as  long  as 
the  first  ray.     The  length  of  the  tin  is  one-third  that  of  the  head. 

The  type  of  the  description  is  the  only  specimen  obtained;  it  was  secured  by  the  steamer 
Blake,  oft'  Barbados,  in  '_';'>7  fathoms.  The  species  is  very  readily  distinguished  from  the 
Mediterranean  species  (A',  telescopus)  by  its  more  slender  form  and  its  large  number  of 
rows  of  scales.  The  length  ot  the  specimen  to  the  base  of  the  caudal  is  120  millimeters,  the 
total  length  137  millimeters.    The  caudal  is  somewhat  imperfect.

Colors  of  the  alcoholic  specimen :  Upper  parts  dark  brown,  lower  parts  light  brown: 
inside  of  mouth  pale.  At  present  there  is  an  appearance  of  a  dark  band  beginning  on  the 
snout  and  continued  behind  the  eye  along  the  lateral  line  to  the  tail.

Similar  to  Apogon,  but  with  4  branchiostegal  rays.  Scales  large,  deciduous.  Two 
dorsal  fins.  Teeth  in  bauds,  rudimentary  on  the  jaws,  wanting  on  the  tongue  and  pala- 
tines.   Eyes  enormous.    Tail  forked. 

This  genus  is  known  only  from  a  single  species  from  the  Straits  of  Messina. 

POMATOMICHTHYS  CONSTANCES,  Giglioli. 
romatomichthye  Constancin*,  Giglioli,  loc.  cit. 

A  Pomatomichthys  with  body  whose  height  is  contained  5  times  in  its  length  (tail 
included),  and  the  depth  of  the  head  3  J.  Diameter  of  the  eye  2\  in  the  length  of  the 
head.  Preoperculum  with  a  single  spine,  but  without  serrated  ridges.  Dorsal  with  7 
spines  in  its  first  division,  and  1  spine  and  9  rays  in  the  second.  Anal  with  2  spines  and 
9  rays.  Pectoral  fins  short.  Ventrals  longer,  extending  to  the  vent.  Lateral  line  entire. 
Scales  upon  caudal  fin.    Color  brownish-yellow  above,  silvery  below  and  on  the  operculum. 

The  type  of  this  species  is  a  single  specimen,  14  centimeters  in  length,  found  at  the 
Straits  of  Messina,  September  28,  1878,  after  a  strong  gale,  which  brought  to  the  surface 
in  immense  abundance  the  rarest  species  of  Sternoptychidce  and  Seopelidce. 

MICROICHTHYS.  Ruppell. 

Microichthys,  Ri'rpPELL,  Verzeieh.   Mus.  Senckenbergianum  Anfgestell.  Samnil.  Fisehe,  1852,  1. 

Apogonids,  said  to  resemble  in  form  and  position  of  the  fins  Ambassis;  lower  jaw 
somewhat  the  longer;  teeth  villiform,  without  canines,  on  the  jaws  and  perhaps  on  pala- 
tines and  tongue.  An  acute  ridge  over  the  eye  extending  backwards  over  the  opercles. 
Scales  large,  deciduous,  opercles  naked.  Lateral  line  commencing  uuder  the  origin  of  the 
second  dorsal  fin. 

This  genus  is  represented  by  a  small  specimen,  obtained  in  the  waters  near  Sicily; 
and  by  another,  in  the  Florence  Museum,  which  we  have  examined,  and  which  has  the 
general  appearance  of  a  deep-sea  fish.  Its  scarcity  would  appear  to  point  to  the  same  idea. 
This  form  was  described  by  Ruppell  under  the  name  Microichthys  Coccoi. 

BREPHOSTOMA,  Aleock. 
Brephostoma,  Alcock,  Ann.  and  Mag.  Nat.  Hist.,  VI,  201,  September,  1890. 

A  (Jhilodcpterid  with  body  low,  rather  elongate,  and  with  delicate  tissues  characteristic 
of  abyssal  fishes.  Head  large,  without  keels  or  spines;  preoperculum  with  a  double  edge. 
Mouth  small,  oblique,  weak,  and  without  teeth.  Eyes  large,  lateral.  Two  separate  dorsal 
fins,  the  first  less  developed,  with  5  spines.  Anal  tin  similar  to  second  dorsal,  with  1

ACROPOMA,  Temminck  and  Schlegel. 
Acropoma,  Temminck  and  Schlegel,  Fauna  Japonica,  Poissons,  31. 

Seven  braBchiostegals.  Teeth  villi  loin,,  with  canines  in  both  the  jaws;  teeth  on  the 
palatine  bones.  Two  dorsals,  the  Qxstwith  7  (8)  Bpines,  the  anal  tin  with  3.  Operculum 
produced  into  a  long  denticulated  point,  preoperculum  entire.  Anus  nearer  the  root  of 
the  ventrals  than  the  origin  of  the  anal.    Scales  moderate,  deciduous,  minutely  ciliated. 

One  species  of  the  single  genus  of  this  family,  Acropoma  philippmense, Giinther,  (Chal- 
lenger Report,  Pari  vi,  ">1 :  xxii,  15)  was  found  near  the  Philippine  Islands  by  the  Challenger 
at  a  depth  of  82  to  102  fathoms. 


Family  SCOMBROPID/E. 


Scombropida,  Gill,  MS. 


Percoidea,  with  teeth  on  jaws,  vomer  and  palatines,  and  long,  strong  canines  in  both 
jaws,  sometimes  barbed.  Bones  of  skull  without  deuticulations.  Operculum  with  2  weak 
spines.    Scales  rather  small,  very  thin,  smooth.    (Gill.)

Latebrm,  Poey,  Mem.  Hist.  Nat.  Cuba,  II,  1858,  158. 

Scombropids  having  2  long  canine  teeth  in  the  upper  jaw  and  a  series  of  similar  teeth  in 
the  lower.  First  dorsal  with  8  spines;  anal  with  3  spines.  Bones  of  the  skull  without 
deuticulations.     Spines  feeble.    Lower  jaw  longest. 


Scombrops  emu  >dipteroides. 


This  genus  is  represented  in  the  Japanese  Sea  by  a  single  species,  8.  chilodipteroides, 
obtained  by  the  Dutch  naturalists  and  by  the  Challenger  off  Inosima,  Japan,  at  a  depth  of 
345  fathoms.    The  Challenger  specimen  was  1G  inches  long. 

SCOMBROPS  OCULATUS,  Poey. 

Latebrus  oculatim,  Poey,  Mem.  Hist.  Nat.  Cuba,  n,  1858,  168,  PI.  xm,  Figs.  11,12  (jaws  with  teeth);  PI,  xiv, 
fig.  2  (outline). — GOnther,  Challenger  Report,  xxn,  1887,  14. 

Body  elongate,  its  height  contained  4jj  times  in  its  total  length;  the  head  3J.  The  eye 
is  very  large,  its  diameter  contained  3i  times  in  the  length  of  the  head.  The  nostrils  have 
vertical  apertures,  and  are  near  the  orbit.  The  length  of  the  maxillary  is  four-fifths  that  of 
the  diameter  of  the  eye.  The  suprascapular  bone  projects.  The  premaxillary  bears  about 
12  canine  teeth;  there  are  2  to  4  teeth  longer  than  the  others  on  its  anterior  portion  on  the 
inner  edge.     The  teeth  of  the  mandible  are  a  little  longer  than  those  on  the  maxillary. 

'fhe  first  dorsal  originates  in  the  vertical  from  the  lower  base  of  the  pectoral,  and  the 
second  over  the  vent  but  a  little  in  advance  of  it.  The  second  dorsal  and  the  anal  are 
similar  in  form  and  height;  they  are  triangular,  with  sharp  angle,  and  emarginate.  The 
caudal  is  forked.    The  first  spine  of  the  dorsal  is  feeble,  although  nearly  as  high  as  the

second,  which  is  the  longest.  The  spinous  rays  of  the  second  dorsal  and  the  anal,  and 
those  in  the  ventral,  have  their  points  covered.  The  scales  are  large,  deciduous,  from  45 
to  50  between  the  shoulder  and  the  tail;  they  are  thin,  with  smooth  edges;  they  cover  the 
entire  body  except  the  lips.    The  vertical  fins  are  also  scaly,  except  the  first  dorsal. 

Radial  formula:  D.  VII,  I,  14;  A.  Ill,  12;  P.  16;  V.  I,  5;  C.  17. 

Color  brownish  violet,  lighter  upon  the  belly. 

This  fish,  according  to  Poey,  is  rare  and  inhabits  great  depths.  In  the  month  of 
October  he  has  seen  individuals  weighing  14  pounds. 

Dr.  Griinther  remarks  that,  but  for  the  barbed  teeth,  he  would  be  disposed  to  unite  this 
species  with  Scombrops  chilodipteroides,  but  we  should  hesitate  to  follow  his  lead,  since  the 
scales  iu  the  latter  are  considerably  smaller,  the  body  apparently  more  slender,  the  fins 
longer  and  stronger,  and  the  two  dorsals  more  closely  approximated,  while  the  lower  jaw 
would  appear  to  be  longer,  and  the  second  dorsal  planted  (relatively  to  the  vent)  much 
farther  forward. 

HYPOCLYDONIA,  Goode  and  Bean,  n.  g. 

This  genus  resembles  Scombrops  in  form  and  is  closely  related  to  it,  but  (1)  none  of  the 
vertical  fins  are  scaly;  (2)  the  tongue  is  toothless;  (3)  the  soft  dorsal  and  anal  have  few  rays. 

The  body  is  covered  with  thin,  deciduous,  cycloid  scales.  The  entire  head  is  scaly  with 
the  exception  of  the  angle  of  the  preoperculum,  but  the  scales  of  the  head  are  deeply  im- 
bedded in  the  skin  and  are  covered  by  minute  pores,  so  that  their  outlines  are  almost  entirely 
concealed.  Eye  large.  Mouth  moderately  large;  the  upper  jaw  slightly  protractile.  Teeth 
iu  the  intermaxilla  minute  in  broad  bands  which  are  separated  at  the  symphysis  by  a  nar- 
row, naked  interspace.  A  pair  of  strong  canines  near  the  symphysis  of  the  iutermaxilla- 
ries.  The  mandible  has  a  marked  concavity  in  front  on  each  side  of  the  symphysis,  this 
concavity  being  armed  with  a  band  of  minute  teeth.  Four  small  canine  like  teeth  in  an 
irregular  group  at  the  symphysis;  5  additional  canines  on  the  mandible,  increasing  in  size 
backward  and  continued  behind  by  a  short,  narrow  band  of  minute  teeth.  Minute  teeth  on 
the  vomer  in  a  triangular  patch.  Palatine  teeth  in  bands,  which  are  broadest  in  front. 
Anterior  nostril  small,  circular,  not  tubular.  Posterior  nostril  in  a  long  wedge-shaped  slit. 
Maxilla  dilated  posteriorly.  The  lower  lip  well  developed,  broadly  attached  to  the  under 
surface  of  the  maxilla.  Preoperculum  minutely  serrated  behind  and  below ;  operculum  with 
two  thin,  flat  spines. 

Branchiostegals  7;  gill-rakers  in  moderate  number,  rather  stout;  gill  lamina?  well 
developed;  a  moderate-sized  slit  behind  the  fourth  gill;  pseudobranchiae  well  developed;  a 
glandular  organ  iu  the  upper  angle  of  the  gill  opening;  fins  well  developed,  the  spinous 
dorsal  longer  than  the  second  dorsal;  dorsal  with  9,  anal  with  2  spines;  ventrals  long;  scales 
large,  thin,  cycloid,  deciduous;  lateral  line  high  up  with  a  gradual  curve  nearly  following 
the  outline  of  the  back. 

HYPOCLYDONIA  BELLA,  Goode  and  Bean,  n.  s.     (Figure  237.) 

The  largest  specimen  taken  by  the  Alba'ross  is  90  millimeters  long.  The  greatest 
height  of  the  body  is  contained  three  and  two  third  times  iu  the  total  without  caudal.  The 
least  height  of  the  tail  equals  the  length  of  the  eye.  The  length  of  the  head  is  one-third 
of  the  total  without  caudal.  The  eye  is  two-sevenths  as  long  as  the  head  and  a  little 
greater  than  the  width  of  the  interorbital  space.  The  snout  is  two-thirds  as  long  as  the 
eye.  The  maxilla  reaches  nearly  to  below  the  middle  of  the  eye;  its  length  is  two-fifths 
the  length  of  the  head.  The  upper  jaw  is  contained  two  audoue-third  times  in  the  length 
of  the  head.  The  length  of  the  mandible  is  one-half  the  length  of  the  head.  The  spinous 
dorsal  begins  over  the  origin  of  the  pectoral.  The  first  spine  is  very  short,  less  than  one- 
third  as  long  as  the  second  and  not  much  longer  than  the  last ;  the  third  and  longest  spine 
is  as  long  as  the  postorbital  part  of  the  head.  The  interspace  between  the  two  dorsals  is 
very  short.  The  longest  ray  of  the  soft  dorsal  is  two  thirds  the  length  of  the  mandible.  The 
anal  originates  under  the  middle  of  the  soft  dorsal:  the  length  of  its  base  equals  the  length

of  the  eye.    The  first  spine  is  less  than  one-half  as  long  as  the  second,  which  is  about  two 
thirds  as  long  as  the  eye.    The  anal  spines  are  slender.    The  longest  anal  ray  equals  the 
postorbital  pari  of  the  dead.     The  pectoral  reaches  to  below  the  origin  of  the  soft    dorsal: 
its  length  equals  that  of  the  head  without  the  snout.     The  ventral  begins  slightly  in  ail 
vance  of  the  origin  of  the  pectoral  and  it  is  nearly  as  long  as  the  pectoral,  its  length  one- 
quarter  of  the  total  without  caudal.

Serranoid  fishes,  with  comparatively  elongate  body.  No  supplemental  bone  to  the  max- 
illary. Teeth  small,  in  broad  bauds.  Top  of  head  naked,  supraoccipital  crest  prominent, 
encroaching  somewhat  on  the  frontal  region.  No  hooked  spinules  on  the  lower  limb  of  the 
preoperculum.  Scales  large.  Dorsal  spines  slender,  the  third  a  little  elevated;  some  of 
them  with  dermal  appendages  or  filaments.  Caudal  tin  not  lunate,  ending  in  3  bands,  the

horizontal  below  last  rays  of  dorsal.  Snout  blunt;  mouth  oblique;  maxillary  broad  and 
scaly.  Fins  with  a  tendency  to  filamentous  production  of  the  rays.  Caudal  forked.  (Jor- 
dan.) 

This  genus  has  been  found  in  deep  water  in  the  Pacific.  Anthias  megalepis,  Giin- 
ther,*  was  taken  off  the  Ki  Islands,  at  1-10  fathoms,  in  company  with  the  Centropristis 
already  referred  to,  and  Anthias  eos,  Gilbert,!  taken  in  the  Gulf  of  California  at  112  fathoms. 

A  specimen  (Cat.  No.  37346,  U.  S.  N".  M.)  obtained  by  the  Fish  Hawk,  has  been  mis- 
placed, and  cannot  now  be  fully  described.  The  name  Anthias  aquilonaris  has  been  pro- 
posed by  us  for  it.     It  is  allied  to  Anthias  oculatus,  C.  &  V. 

A  note  indicates  that  the  length  of  its  head  was  equal  to  the  height  of  its  body,  which 
is  contained  2J  times  in  the  total  length  (without  caudal).  The  diameter  of  the  orbit  is  con- 
tained 3^  times  in  the  head.  The  maxillary  bone  was  naked,  rather  than  scaled  as  in  A. 
oculatus;  and  the  scales  numbered  53  in  the  lateral  line,  7  above  and  14  below.  The  radial 
formula  was  D.  x,  11 ;  A.  in,  8. 

A  small  specimen,  possibly  of  the  same  species,  was  obtained  by  the  Blake,  off  Domi- 
nica, at  station  cvi,  in  521  fathoms;  but  since  this  is  less  than  2  inches  long  and  the 
subject  of  the  above  note  was  9,  it  is  impossible  to  confirm  the  identification  in  the 
absence  of  the  larger  specimen.

PolymixiidcE,  Gill,  Arr.  Fam.  Fish.  1872,  name  only  (No.  99);  Johnson's  Cyclopaedia,  1323. 

A  family  of  teleocephalous  fishes  distinguished  by  the  peculiar  union  of  characters. 
The  body  is  rather  elongated  and  compressed;   the  scales  are  not  serrated;  the  lateral  line 


POLT.MIXIA  NOBILIS. 

is  continuous  with  the  back;  head  compressed  and  with  a  decurved  profile;  preoperculum 
serrated;  mouth  with  a  lateral  and  nearly  horizontal  cleft;  teeth  villiforin,  on  the  jaws  as 
well  as  palate;  branchiostegal  apertures  large;  branchiostegal  rays  4;  dorsal  moderately 
elongated, with  several  spines,  increasing  backward;  anal  opposite  the  posterior  portion  of 
the  dorsal,  armed  with  3  or  4  spiues;  pectorals  with  branched  rays;  ventral  tins  thoracic, 
each  with  a  spine  and  6  or  7  rays.  The  skeleton  has  the  vertebrae  in  increased  number  (29). 
The  family  is  distinguished  by  the  combiuatiou  of  chin  barbels,  increased  number  of  rays. 
and  small  number  of  branehiostegals.  Its  affinities  are  doubtful,  but  on  the  wdiole  seem  to 
be  rather  with  the  Mullidee.     (Gill.)

A  Polymixia,  with  compressed,  elevated  body,  whose  height  is  contained  3g  times  in 
its  total  length,  and  is  nearly  equal  to  the  length  of  head.  Head  with  blunt  snout  and 
slightly  projecting  upper  jaw.  Mouth  wide,  the  maxillary  ending  beyond  vertical  from 
posterior  margin  of  orbit,  and  terminating  posteriorly  in  a  broad  plate.  Teeth  in  broad, 
velvet-like  bands,  present  on  jaws,  palatines,  pterygoids,  vomerines,  tongue,  and  branchial 
arches.  Eye  placed  high,  but  below  upper  profile  of  head;  its  diameter  contained  about 
3  times  in  the  head's  length.  Opercles  spineless.  Scales  oblique,  irregular,  completely 
covering  body  and  head;  48-54  in  lateral  line. 

Eadial  formula:  D.  v.  28-38;  A.  111-IV,  16-18;  V.  1,  6-7. 

Color  a  soft  violet,  brownish,  opalescent  on  the  back  and  fins.  Upper  margin  of  orbit, 
and  two  bands  above  the  snout,  golden  green;  maxillary  roseate,  inner  margin  of  caudal 
lobes  whitish.     Iris  white,  opalescent. 

This  species  has  been  exhaustively  studied  by  Dr.  Giinther,  who  has  access  to  speci- 
mens from  various  parts  of  the  tropical  and  subtropical  Atlantic,  namely,  near  Madeira, 
the  <  'anary  Islands.  St.  Helena,  and  Cuba.  The  Challenger  expedition  brought  home  speci- 
mens from  the  Sea  of  Japan,  where  they  were  captured  oil'  Inosima  at  a  depth  of  345  fath- 
oms.    The  Investigator  took  it  in  the  Andaman  seas,  in  271  fathoms.     The  species  has  been 

found  by  Poey  at  Cuba.     The  British  .Museum  in  1886  received  a  specimen  IV Mauritius, 

the  first  of  its  kind  which  the  fishermen  remembered  to  have  seen.  The  wide  geographical 
range  of  this  form  is  remarkable,  although  it  is  possible  that  it  does  not  descend  to  veJ y 
great  depths  or  extend  beyond  the  tropical  or  subtropical  zones.  From  comparison  of  all 
the  materials  in  his  possession,  Dr.  Giinther  has  become  convinced  that  the  differences 
on  which  he  formerly  based  his  conclusion  that  there  were  three  species,  were  really  not 
sufficiently  marked  to  justify  his  conclusions.

and  it  is  probable  that  its  occurrence  out  of  the  shallows  was  not  positively  determined.

This  genus,  which  is  widely  distributed  throughout  the  East  Indian  seas,  is  represented 
in  the  shore  faunas  of  the  Atlantic  basin  by  two  European  and  two  tropical  American 
forms.  S.  Plumieri,  Schneider,  occurs  throughout  the  West  Indies  and  north  to  the  Ber- 
mudas, and  is  always  a  shoal-water  form.  S.  irasiliensis,  C.  &  V.,  a  smaller  scaled  form 
with  shorter  body,  is  a  shore  form  from  the  coast  of  Brazil.  The  European  forms  both 
occur  in  the  Mediterranean.  The  Italians  have  noted  them  from  Genoa,  Naples,  and  Sicily 
and  around  to  the  head  of  the  Adriatic,  the  French  from  Nice,  Cette,  and  Marseilles,  and 
the  Portuguese  from  Lisbon.  Both  have  been  observed  in  the  Gulf  of  Gascony,  at  Biarritz 
and  La  Itochelle.  S.  scrofa  has  not  been  seen  on  the  coasts  of  Vendee  or  farther  north, 
but  is  abundant  at  Madeira,  where  there  is  also  a  local  species,  ,v.  ustulata,  to  which  it  is 
closely  allied.  S.porcus  follows  the  French  coast  as  far  north  as  Dieppe.  Cuvier  was 
entirely  in  error  in  supposing  that  it  occurs  in  the  western  Atlantic,  but  appears  to  have 
had  specimens  from  Teneriffe.  Lowe's  remarks  about  Seorpcena  scrofa  and  its  habits  at 
Madeira  are  very  important,  lie  notices  the  tendency  of  this  form  to  become  modified  for 
residence  in  deeper  regions.

246  DEEP-SEA    FISHES    OF   THE    ATLANTIC    BASIN. 

The  above  description  applies  to  the  species  as  a  whole.  Lowe  separates  his  variety 
obesa  on  the  following  specifications:  "Major,  miniacea,  pallida,  maculis  obsoletioribus; 
corpore  altiore  s.  obeso;  oculisfere  majoribus." 

8.  scrqfa  obesa  is  a  deep-water  form,  living  "in  profundioribus,  a  littori  procul."  The 
fishermen  of  Madeira  distinguish  it,  calling  it  Garneiro  de  Font,  while  the  inshore  type  is 
known  as  Garneiro  de  Bolo.  They  grow  to  be  from  15  to  20  inches  long,  and  have  the 
belly  somewhat  more  prominent,  and  larger  eyes,  and  lighter  colors.  Lowe  is  not  posi- 
tive that  the  two  forms  should  be  distinguished,  even  as  varieties.  We  include  obesa 
among  the  deep-water  forms  in  order  to  invite  further  investigation  of  the  question  whether 
8.  scrofa  may  not  be  dimorphic  like  Sebastes  norvegicus. 

Risso  distinguished  a  color,  or  depth,  variety  in  this  species  at  Nice,  which  occurred  in 
the  coralline  zones,  and  was  ••</'  un  brim  rouge  de  laque,  marbrle  de  brim,  de  blanc  et  de  gris 
couverte  d'appendices  denteUes  et  de  cirrhes  rougeatres"  (Hist.  Nat.  Europe  Merid.,  in,  371). 
He  also  describes  a  pallid  form  under  the  name  Scorpcena  lutea.  This  is  not  recognized  by 
modern  Mediterranean  ichthyologists.  Lowe  suggests  that  it  may  be  founded  upon  some 
extreme  state  of  his  obesa, 

Scorpcena  scrofa  is  preeminently  a  Mediterranean  species.  It  has  been  observed  at 
Nice,  Cette,  Genoa,  Leghorn,  Naples.  Montecristo,  Magdalena,  Alghero,  Cagliari  (Corsica), 
Messina,  Catania.  Malta.  Venice,  Trieste,  Dalmatia.  and  North  Africa.  Also  from  the 
River  Niger,  Lisbon,  Gulf  of  Gascony,  St.  Jean  de  Luzon.  Arcachon,  Gironde,  La  Kochelle. 
Also  from  Madeira  and  the  Azores. 

Scorpcena  ustulata,  Lowe,  Proc.  Zool.  Soc.  1S60,  36,  is  a  Madeiran  form  of  small  size, 
closely  allied  to  8.  scrofa,  but  with  cheeks  aud  opercles  pustulate  or  granulated. 

Two  additional  species  are  now  added  to  the  deep-sea  forms  of  the  Atlantic. 

SCOEP.EXA  CRISTULATA,  Goode  aud  Beax.  n.  8.     (Figure  242). 

The  greatest  depth  of  the  body  (50  millimeters)  is  one  third  of  the  standard  length:  the 
least  height  of  the  tail  (11  millimeters)  equals  the  length  of  the  snout.  The  length  of  the 
head  (68  millimeters)  is  contained  21-  times  in  the  standard  length,  and  is  about  twice  the 
length  of  the  upper  jaw.  The  width  of  the  iuterorbital  space  (8  millimeters)  is  one-fourth 
the  length  of  the  upper  jaw;  this  space  is  moderately  concave  and  is  incompletely  scaled. 
The  maxilla  reaches  to  the  vertical  from  the  posterior  edge  of  the  pupil;  its  length  (30 
millimeters)  is  one-fifth  of  the  standard  length.  The  mandible  reaches  to  below  the  pos- 
terior margin  of  the  eye,  its  length  (38  millimeters)  slightly  more  than  the  postorbital  part 
of  the  head.  Teeth  in  villiforni  bands  in  the  jaws  and  on  the  vomer  and  palate.  A  naked 
space  at  the  symphysis  of  the  intermaxillaries.  A  pair  of  spines  on  the  preorbital;  six 
spines  on  the  suborbital  carina:  live  on  the  border  of  the  preoperculum,  of  which  the  up- 
permost is  the  largest,  and  with  a  supplementary  spine  at  its  base.  Nasal  spines  developed ; 
three  supraorbital  spines  on  each  side  and  three  more  on  each  side  of  the  vertex  aud  nape. 
A  postocular  spine,  a  tympanic  and  two  humerals.  Two  thin  flat  spines  on  the  operculum. 
Almost  all  the  spines  of  the  head  have  short  filaments  behind  them. 

The  length  of  the  eye  (20  millimeters)  is  contained  nearly  3.J  times  in  the  length  of  the 
head  and  equals  two-thirds  the  length  of  the  maxilla.  The  length  of  the  snout  (14  millime- 
ters) equals  the  least  height  of  the  tail.  The  anterior  nostril  is  nearer  to  the  eye  than  to 
tlie  tip  of  the  snout:  it  is  tubular  and  has  prolongations  behind  consisting  of  two  dark  col- 
ored filaments.  The  longest  filaments  above  the  orbit  are  scarcely  one-third  as  long  as  the 
eye.  The  posterior  nostril  is  scarcely  tubular:  the  distance  between  the  anterior  nostrils  is 
one-half  the  length  of  tin-  eye.  The  integument  covering  the  suprauiaxilla  is  finely  scaled. 
The  character  of  the  gill-rakers  is  very  different  from  those  of  Poniinas;  they  are  short, 
stout,  and  the  club-shaped  extremity  is  armed  with  minute  spines.  There  are  i  developed 
and  2  rudiments  above  the  angle  and  S  below,  beside^  .">  sessile  rudiments.  Pseudobranchia; 
present.  The  distance  of  the  spinous  dorsal  from  the  tip  of  the  snout  (67  millimeters) 
equals  twice  the  length  of  the  upper  jaw.  The  length  of  the  first  spine  (8  millimeters) 
equals  the  width  of  the  iuterorbital  space;  the  length  of  the  second  spine  is  nearly  twice

that  of  the  first;  the  length  of  the  third  (22  millimeters)  is  about  one-third  the  length  of  the 
head;  the  fourth  is  about  equal  to  the  third,  the  fifth  is  broken  off,  the  sixth  is  slightly 
shorter  than  the  third,  and  the  rest  decrease  gradually  in  size  to  the  penultimate  spine, 
whose  length  (11  millimeters)  is  a  little  more  than  one-halt  the  length  of  the  last  i  l'.i  milli- 
meters).   The  longest  ray  of  the  sofl  dorsal  (26  millimeters)  equals  one-half  the  length  of 

the  base  of  the  spinous  dorsal.     Length  of  the  middle  caudal  rays  (32  milli ters)  is  nearly 

one  half  the  Length  of  the  head.  The  caudal  is  slightly  rounded  when  expanded.  The 
anal  origin  is  under  the  last  spine  of  the  dorsal.  The  length  of  the  anal  base  (17  millimeters) 
equals  one-half  of  the  postorbital  part  of  the  head.  The  spines  are  all  stout,  the  length  of 
the  first  (10  millimeters)  is  aboul  one-half  of  the  second  (21  millimeters)  and  exactly  one- 
half  of  the  third  (20  millimeters.)  The  length  of  the  longesl  ray  (24  millimeters)  is  about 
one  third  the  length  of  the  head.  The  ventral  does  not  quite  reach  to  the  vent :  its  length 
(31  millimeters)  slightly  greater  than  that  of  the  maxilla.  The  pectoral  extends  to  the  verti- 
cal from  the  tenth  spine  of  the  dorsal.  It  reaches,  also,  to  above  the  vent.  It  has  the 
lower  8  or  9  rays  simple;  the  first  ray,  also,  is  simple,  and  the  intervening  13  rays  are 
divided.

SCORP^ENA  AGASSIZII,  Goode  and  Bean,  n.  s.     (Figure  243.) 

The  greatest  height  of  the  body  (32  millimeters)  is  about  one-third  of  the  standard 
length.  The  least  height  of  the  tail  (9  millimeters)  equals  one-half  the  length  of  the  third 
dorsal  spine  and  nearly  one-half  the  length  of  the  maxilla  The  length  of  the  head  (38 
millimeters)  equals  the  length  of  the  base  of  the  spinous  dorsal. 

The  greatest  width  of  the  head  (21  millimeters)  equals  one  half  its  length  without  the 
postorbital  part.  The  width  of  the  interorbital  area  (8  millimeters)  is  half  the  length  of 
the  postorbital  part  of  the  head.  The  length  of  the  eye  (15  millimeters)  is  contained  2;; 
times  in  the  greatest  length  and  6  times  in  the  standard  length.  The  supraocular  ridge  is 
elevated  above  the  general  profile,  and  the  snout  is  abruptly  declivous  and  very  short; 
its  length  (6  millimeters)  is  less  than  one-hall'  the  length  of  the  eye.  The  maxilla  reaches 
to  the  vertical  from  the  posterior  margin  of  the  orbit,  its  length  (20  millimeters)  is  one-half 
the  length  of  the  head  and  two-ninths  of  the  standard  length.  The  mandible  reaches 
behind  the  vertical  from  the  posterior  margin  of  the  orbit;  its  length  (22  millimeters) 
equals  nearly  one-fourth  of  the  standard  length:  it  has  a  prominent  knob  at  the  symphy- 
sis. The  strong  preorbital  spines  overhang  the  supra-maxilla.  The  nasal  spines  small.

This  genus  has  not  been  fully  characterized,  and  it  is  difficult  to  see  how  it  will  finally 
be  separated  from  Scorpcena. 

It  includes  a  single  species,  Bathysebastes  albescens,  obtained  from  the  Sea  of  Japan. 
Gunther,  though  stating  that  "  nothing  definite  is  known  about  the  depths  which  it  inhab-

HELICOLENUS,  Goode  and  Bean  n.  g. 

Scorpaenids  with  body  oblong,  somewhat  compressed;  large  head,  ctenoid  scales  on  its 
top,  and  on  the  cheeks  and  opercles.  Several  series  of  spinous  ridges  on  the  head,  but  no

A  Helicolenus  with  body  and  bead  somewhat  compressed,  and  back  arcuate;  its  height  at 
the  ventrals  2f  in  its  total  length  (without  caudal) ;  the  length  of  the  head  about  2£.  The 
second  dorsal  spine  about  equal  in  length  to  the  fourth,  and  both  shorter  than  the  third. 
Scales  moderate,  finely  pectinate  upon  the  margins,  presenting  a  rough  surface.  No  der- 
mal flaps.  Preopercular  spines  five  in  number,  somewhat  conspicuous,  and  uniform  in 
size,  except  the  second,  which  is  a  little  longer  and  sharper  than  the  others.  Upper  margin 
of  the  eye  touching  upper  profile  of  head,  its  diameter  3  to  3i  in  length  of  head.  Max- 
illary long,  somewhat  curved,  its  posterior  extremity  reaching  about  to  the  vertical  from 
the  posterior  margin  of  the  pupil.  Lower  jaw  equal  in  length  to  the  upper,  or  sometimes 
passing  slightly  beyond  it.  Upper  jaw  notched,  the  lower  with  a  median  tubercle  corres- 
ponding to  the  notch. 

The  lateral  line  is  distant  from  the  dorsal  outline  a  space  equal  to  three-quarters  the 
diameter  of  the  orbit,  and  follows  a  nearly  straight  line  to  the  point  below  the  end  of  the 
soft  dorsal,  thence  with  a  gentle  curve  to  a  point  slightly  above  the  middle  of  the  base  of 
the  caudal.  The  number  of  longitudinal  rows  of  scales  is  hard  to  determine.  There  appear 
to  be  about  50  and  28-30  of  them  are  tube  bearing. 

The  dorsal  fin  is  inserted  above  the  inner,  upper  angle  of  the  opercular  flap,  and  the 
length  of  its  spinous  portion  is  considerably  less  than  the  length  of  the  head.  Its  second, 
third  and  fourth  spines  are  the  longest,  the  third  slightly  exceeding  the  other  two;  while 
the  following  ones  gradually  decrease  to  the  eleventh,  which  is  considerably  shorter  than 
the  tenth,  which  is  equal  to  the  fifth.  The  soft  dorsal  is  composed  of  12  rays,  the  last 
bifid;  and  its  height  at  its  middle  is  considerably  greater  than  that  of  the  third  dorsal 
spine,  anil  nearly  equal  to  that  of  the  postocular  portion  of  the  head;  its  rays  project  far 
beyond  the  membranes.  The  anal  is  inserted  under  the  origin  of  the  soft  dorsal,  and  is 
nearly  equal  to  it  in  height.  The  tip  of  the  ventral  extends  beyond  the  vent,  the  lower 
pectoral  rays  sometimes  going  to  the  same  vertical.  The  base  of  the  pectoral  is  equal  in 
width  to  the  postocular  portion  of  the  head,  and  almost  equal  to  its  longest  or  median 
rays,  which  reach  to  the  vertical  from  the  vent;  the  tin  is  broad  and  fan-shaped;  its  first 
two  raj  s  are  simple,  the  nine  following  branched,  the  last  eight  simple  ami  slender,  nearly 
half  of  their  extremities  free  from  connecting  membranes. 

Color,  red  above,  white  below,  with  the  color  of  the  back  extending  in  transverse

De  la  Roche  states  that  at  Iviga  this  form  is  found  only  at  considerable  depths,  outside  of 
the  regions  commonly  frequented  by  the  fishermen;  indeed,  that  it  is  very  rare,  or  scarcely 
at  all  known,  in  the  markets  of  the  towns  where  the  fishermen  are  not  in  the  habit  of  going 
far  out  to  sea.  He  saw  many  individuals  taken  off  Iviga  at  a  depth  of  200  to  290  meters, 
and  in  the  vicinity  of  Barcelona  saw  the  same  species  from  a  depth  of  540  meters.  At  iviga 
the  species  is  known  as  the  Strait  imperial,  ami  at  Barcelona  as  the  Fanegal. 

Risso  says  that  the  specimens  seen  by  him  at  Nice  corresponded  perfectly  with  the 
description  and  figure  ofDela  Roche,  and  thai  it  is  very  common  in  that  part  of  the  Medi- 
terranean, where  it  is  known  as  the  Cardouniera;  that  itgrows  to  a  length  of  30  centimeters 
and   a  weight  of  2  kilograms;  that  it  is  obtained   on  rocky  bottoms  at  considerable  depths 

throughout  the  entire  year,  and  that  he  has  observed  females  full  of  eggs  in  summer.     Gi S- 

trini  identities  it  from  Naples  under  the  name  Scor/ano  difunal,  and  says  it  is  known  only 
at  great  depths.  His  diagnosis  corresponds  fairly  well  with  that  of  De  la  Roche,  but  we  do 
not  know  whether  it  is  original  or  quoted.  Giglioli  identities  the  same  from  Genoa,  Messina,

250  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

Outside  of  the  Mediterranean  it  has  been  identified  by  Capello  from  Lisbon,  where  he 
says  it  is  very  rare  and  found  only  in  summer. 

Moreau  says  he  has  found  it  common  at  Marseilles,  and  identifies  with  the  species  in- 
dividuals observed  by  him  at  St.  Jean  de  Luz,  where  it  is  very  cominou,  and  at  Biarritz, 
where  it  is  known  by  the  Basque  name  Grabra;  at  Valence  and  at  Arcachon,  where  it  is 
exceedingly  rare,  M.  Lafout  having  obtained  a  single  specimen,  trawled  and  brought  to 
market  in  February,  1871. 

The  species  also  occurs  in  the  western  Atlantic  in  numerous  localities,  having  been 
first  discovered  by  the  Fish  Hawk,  in  1880,  oft'  Narragansett  Bay.  The  western  form  pre- 
sents no  characters  by  which  it  can  be  distinguished  from  that  of  the  Mediterranean,  except 
that  the  lower  rays  of  its  pectoral  tin  are  somewhat  more  prolonged  in  the  example  studied 
by  us.  This  also  has  a  perfectly  smooth  suborbital  keel,  while  most  of  the  western  speci- 
mens have  a  small  spine  on  the  anterior  portion  of  this  keel.  This  character  is  of  little  mo- 
ment.   In  some  of  our  specimens  the  spiue  is  present  on  one  side  and  absent  on  the  other. 

In  comparing  H.  dactylopterus  with  //.  maderensis,  special  attention  should  be  paid  to  the 
preopercular  spines.  The  limb  of  the  preopercuhun  is  much  more  nearly  vertical  in  the 
Madeiran  type,  and  the  spines  are  more  prominent,  and  their  axes  (as  shown  in  Lowe's  figure) 
are  parallel  with  each  other  and  with  the  central  axis  of  the  fish's  body.  This  tendency  to 
parallelism  is  noticeable  in  some  of  our  specimens  of  //.  dactylopterus.  The  Madeiran  fish 
has  a  much  more  heavily  armed  head,  and  its  coloration  is  different.  The  back  part  of  the 
mouth  of  7/.  dactylopterus  is  plumbeous  in  both  Mediterranean  and  American  specimens,  but 
it  seems  hardly  probable  that  it  can  have  been  as  conspicuously  black  as  in  that  of  Madeira. 

In  addition  to  the  American  specimens,  we  have  had  before  us  a  specimen  obtained  by 
President  Jordan  at  G-euoa  (U.  S.  Nat.  Mus.  Cat.  No.  29783). 

HELICOLENUS  MADEKENSIS,  <■ e   A   Bean,  n.  s. 

Sebaftcs  imperialis,  LOWE,  Synopsis,  Fishes  of  Madeira,  175:  Fishes  of  Madeira.  171,  pi.  xxiv. 

A  Helioolenus,  with  body  moderately  compressed,  as  high  at  the  origin  of  the  anal  as  at 
that  of  the  dorsal,  with  its  profile  flatly  arched  to  a  height  equal  to  about  one-third  the 
diameter  of  the  orbit.  Its  greatest  height,  at  the  origin  of  the  ventrals,  is  equal  to  the 
length  of  the  head  (measured  from  the  tip  of  the  snout),  and  slightly  exceeds  one-third  the 
length  of  the  body;  the  thickness,  which  is  greatest  behind  the  eyes,  about  one-half  of  its 
height. 

Eye  large,  the  upper  limb  of  the  orbit  encroaching  upon  the  upper  profile  of  the  head ; 
its  diameter  equal  to  the  length  of  the  snout,  but  less  than  the  postorbital  portion  of  the 
head,  aud  consequently  less  than  one-third  the  Length  of  the  head.  The  iuterorbital  space 
deep  and  strongly  ribbed,  its  width  scarcely  one-half  the  diameter  of  the  orbit;  a  promi- 
nent depression  in  the  occipital  region.  Suborbital  equally  feeble,  aculeate,  with  generally 
only  one  slight  spiue.  Preoperculum  with  five  strong  spines,  equidistant  and  regularly 
arranged,  the  uppermost,  which  is  opposite  the  end  of  the  suborbital  keel,  or  sometimes  one 
below  it,  a  little  the  most  conspicuous,  all  having  the  same  horizontal  or  parallel  direction, 
being  nearly  straight  or  but  slightly  hooking  upwards.  The  scapulary  aud  two  suprascapu- 
lary  spines  small  and  crowded,  forming  the  usual  triangle.  Two  conspicuous  spines  upon 
the  upper  part  of  the  opercular  flap,  below  its  angle;  spines  upon  the  anterior  suborbital 
inconspicuous. 

The  teeth  are  not  described  by  Lowe. 

The  dorsal  begins  slightly  behind  the  upper  anterior  angle  of  the  preoperculum,  and 
(as  shown  in  the  figure)  the  roots  of  the  first  and  second  spines  seem  very  close  together. 
The  second  and  fourth  spiues  are  nearly  equa',  the  third  slightly  exceeding  them  in  length;  the 
fifth,  sixth,  and  seventh  are  nearly  equal;  the  eighth,  ninth,  and  tenth  slightly  decreasing 
from  one  to  the  other,  the  ninth  as  long  as  the  first,  which  exceeds  the  twelfth  by  as  much 
as  this  exceeds  the  tenth,  and  the  tenth  exceeds  the  eleventh.  This  fin  is  less  regular  in 
the  diminution  of  the  length  of  its  spines  than  that  in  //.  dactylopterus. 

The  anal  begins  farther  forward  than  in  H.  dactylopterus,  apparently  in  the  vertical  from

the  base  of  the  eleven!  b  dorsal  spine.  The  third  anal  spine  is  somewhat  stouter  and  Longer 
than  the  second)  the  tip  of  the  anal,  when  extended,  does  not  touch  the  vertical  from  the 
end  of  the  base  of  the  sofl  dorsal. 

The  pectoral  is  broad  and  fan-shaped,  the  width  of  its  baseabout  equal  to  the  diameter 
of  the  orbit,  the  uppermosl  of  its  branched  rays  the  longest,  its  middle  rays  aboui  equal  in 
length  to  the  longest  of  the  ventral,  which,  when  extended,  pass  far  beyond  the  vent,  and 
almost,  it'  not  quite,  to  the  origin  of  the  anal.  The  rays  of  the  pectoral  are  arranged  pre- 
cisely as  in  //.  dactylopterm.    Caudal  simple  and  truncate. 

Lateral  line  straighter  than  in  II.  daetylopterw,  bul  slightly  curved  in  its  course  from  the 
head  to  the  middle  of  the  caudal  ped  ii  mde,  and  twice  as  far  from  the  anterior  portion  of  the 
soft  dorsal  as  from  that  of  the  spinous  portion  of  the  tin.  It  consists  of  L'!)  or  .'111  scales, 
each  with  a  little  spine  like  point,  directed  tow  aril  t  he  tail.  The  scales  (as  shown  by  the 
figure)  are  larger  than  in  the  .Mediterranean  form.  Color  pale  scarlet,  with  darker  or 
brighter  broad,  irregular,  scarlet  bands,  often  subdued  with  dusky,  running  down  the  side 
from  the  dorsal  origin  and  disappearing  alter  reaching  the  ventral  origin.  Fins  scarlet, 
immaculate,  the  spiny  part  of  the  dorsal  tin  being  mottled,  and  having  its  spines  and  fila- 
ments tipped  with  white,  and  its  soft  portion,  like,  the  front  of  the  ventral  and  anal  tins, 
edged  with  white.  Head  bright  scarlet,  the  operculum  with  a  patch  of  bluish  black.  The 
back  part  of  the  mouth  lead  color,  the  front  of  mouth  and  tongue  whitish.  Iris  golden, 
shaded  with  brown;  pupil  violet,  opalescent.1 

This  species  is  taken  by  the  Madeiran  fishermen  on  rocky  bottoms  and  at  great  depths, 
with  lines  225  to  350  fathoms  in  length.  It  is  taken  chiefly  in  spring  and  autumn,  neither 
of  which  times,  according  to  Lowe,  is  its  breeding  season,  so  that  he  is  inclined  to  believe 
that  like  P.  dactylopterus,  as  observed  by  Risso,  the  spawning  time  is  in  summer.  The 
Madeirans  call  it  the  Boca  negra,  or  black  mouth,  in  allusion  to  its  conspicuous  blaek  throat, 
and  it  is  also  called  Pai  <li  goto,  or  "tomcat,"  a  name  which  refers  to  the  fact  that  the  eyes 
glisten  strongly  in  the  dark. 

The  name  Sebastes  imperialis  has  no  significance.  Cuvier  and  Valenciennes  had  no 
specimens  except  the  types  of  De  la  Roche,  and  renamed  it  from  some  whimsical  desire  to 
utilize  the  vulgar  name  •■Scrofaini  imperali"  which  the  Sicilians  use  for  some  fish  which  the 
French  ichthyologists  supposed  to  be  identified  with  that  described  from  Ivica.

Scorpaenids  similar  in  form  and  general  structure  to  Helicolenus,  but  having  the  pec- 
toral rays  all  simple  and  their  tips  only  free:  having  six  to  nine  rays  in  the  anal;  the

prominent  retrorse  spines  on  each  suborbital. 


A   yOUNO  PONTINUS. 

The  type  of  this  genus  is  Pontinua  castor  (Poey),  which,  with  the  allied  species;  P. 
pollux,  described  at  the  same  time,  is  probably  a  shoahvater  form,  peculiar  to  the  West 
Indian  fauna.  The  genus  is  apparently  precisely  equivalent  to  QUY&  Sebastoplus,  described 
by  him  in  1803,  of  which  Sebastes  Kuhlii  was  designated  as  the  type.

A  Pontinus,  having  an  oblong,  somewhat  compressed  body,  the  height  of  which  at  the 
origin  of  the  ventral  is  contained  about  3  times  in  its  total  Length  (caudal  excluded) ;  the 
length  of  its  head  2  A  times.  The  space  between  tin-  eyes  slightly  concave,  with  two  Ion 
ridges,  its  width  about  one-eleventh  the  length  of  the  head.  Snout  as  long  as  the  diameter  of 
the  orbit;  lower  jaw  projecting  considerably;  tin-  vertex  is  much  depressed  and  has  several 
prominent  spines,  ami  there  are  long,  lanceolate  laciniae  upon  the  margin  of  the  orbil  and 
in  front  of  it.  The  upper  maxillary  reaches  about  to  the  vertical  from  the  middle  of  the 
eye.  There  arc  3  prominent  spines  upon  the  suborbital  carina,  and  a  long,  sharp  spine  in 
continuation  of  them  upon  the  preoperculum,  with  .'!  or  4  less  conspicuous  spines  below  it 
and  one  above.  The  dorsal  is  continuous  and  comparatively  slightly  notched,  the  twelfth 
and  ninth  dorsal  spines  being  nearly  as  long  as  any  except  the  first,  second,  and  third, 
while  the  first,  tenth,  and  eleventh  are  also  about  equal.  The  anterior  dorsal  ray  is  about 
equal  in  height  to  the  fourth  spine,  and  the  tin  from  that  point  curves  sharply  in  a  sub- 
vertical,  fan-shaped  outline  to  the  caudal  peduncle;  the  second  and  third  dorsal  spines  are 
much  longer  than  the  others.  Anal  inserted  under  the  second  dorsal  ray,  with  .">  stout 
spines,  of  which  the  third  is  the  longest,  being  longer  than  the  fourth  dorsal  ray,  and 
with  o  rays,  closely  set  together,  and  as  long  as  the  longest  dorsal  rays.  Pectoral  with 
broad,  cresceutic  base,  fan-shaped,  when  expanded  reaching  from  the  ventral  line  to  the 
lateral  line.  Ventrals  as  long  as  the  longest  dorsal  spine,  and  inserted  directly  under  the 
pectoral  base,  the  antecedent  spine  as  long  as  the  second  spine  of  the  anal.  Color  red, 
irregularly  blotched  with  brown. 

Radial  formula:  D.  XII,  9-10;  A.  Ill,  o;  V.  I,  5;  about  25  tubes  in  the  lateral  line. 

This  species,  the  Requieme,  was  first  found  in  Madeira,  and  was  named  by  Bowdich, 
and  described  by  Lowe.  The  fishermen  take  it  about  Madeira  with  lines  of  loo  to  250 
fathoms  in  length.  It  grows  to  be  from  12  to  15  inches  long,  and  to  weigh  from  a  pound  to 
a  pound  and  a  quarter.  The  British  Museum  has  specimens  from  the  Canaries,  and  Capello 
records  it  from  Lisbon.  It  has  not  as  yet  been  found  in  the  Western  Atlantic  or  in  the

tinguished from  any  other  species  of  Pontinus  by  the  great  prominence  of  the  second  and 
third  dorsal  spines.     Vaillant  has  printed  an  elaborate  description  of  its  scales.

254  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

Sauvage  declares,  appears  to  be  distinct.  It  is  distinguished  by  the  less  oblique  profile  of 
the  head,  smaller  eye,  shorter  maxillary,  colorless  pharynx,  the  teeth  iu  the  middle  of  the 
upper  jaw  shorter,  4  spines  on  the  preoperculuin  instead  of  5,  the  anal  shorter,  and  the 
scales  different  in  character.  Another  distinctive  character  is  the  presence  of  2  strong 
spines  on  the  suborbital. 

The  space  between  the  posterior  margin  of  the  eye  and  the  origin  of  the  dorsal  is  more 
arched  than  in  the  other  species.  The  height  is  contained  four  times  in  the  length  of  the 
head;  the  opening  of  the  mouth  is  more  horizontal;  the  interocnlar  space  flatter  and 
narrower  between  the  two  crests,  which  are  less  conspicuous.  The  occipital  pit  is  nearly 
square.  The  suborbital  crest  has  .'?  spines,  while  in  H.  dactylopterus  scarcely  any  spines 
are  visible. 

The  teeth  of  the  vomer  are  arranged  m  the  form  of  a  A-  with  angles  less  divergent  than 
in  the  other  species.  Between  the  vomerine  patch  and  the  palatines  there  is  a  considerable 
interval;  the  palatine  band  narrower  anteriorly  and  more  curved.  The  anterior  edge  of  the 
maxillary  is  less  notched,  the  muzzle  blunter.  The  preopercular  space  is  shorter;  the  lateral 
line  is  straighter  iu  its  anterior  portion.  The  space  between  the  extremity  of  the  dorsal 
and  the  origin  of  the  caudal  is  shorter.  The  second  and  third  spines  of  the  dorsal  are  much 
longer  than  those  which  follow,  while  in  11.  dactylopterus  t  he  spines  diminish  regularly  in 
height.     The  fins  are  uniform  brownish-red;  the  caudal  lias  a  lew  black  blotches. 

This  species,  which  Sauvage  considers  allied  to  Helicolenus  dactylopterus,  does  not  belong 
to  the  same  genus.  It  is  suspiciously  close  to  Pontirius  Kuhlii,  but  we  deem  it  unsafe  to 
assume  its  specific  identity  in  species  from  localities  even  so  close  together  as  Sicily  and 
Madeira.  The  description  of  Sauvage  is  therefore  translated  in  full,  and  the.  attention  of 
Mediterranean  ichthyologists  is  especially  directed  to  the  desirability  of  obtaining  further 
material  in  regard  to  this  genus  in  their  waters.

fig.  2.   ' 

A  Pontinus  with  a  comparatively  low  dorsal  convexity,  its  heighl  at  the  origin  of  the 
anal  about  two-thirds  that  at  the  origin  of  the  dorsal,  which  enters  2|  into  the  total  length 
(without  caudal) ;  length  of  head  about  -h  times  in  total  length.  Eye  small,  its  diameter 
about  two  thirds  the  length  of  the  snout,  and  contained  about  four  and  one-half  times  in 
that  of  the  head;  it  touches  but  does  not  encroach  upon  the  upper  profile,  and  (as  shown 
by  the  figure  of  Webb  and  Berthelot)  this  profile  is  not  deeply  depressed,  either  in  front 
or  behind  it.  Interorbital  space  nearly  Hat,  its  width  two  thirds  the  diameter  of  the  eye, 
with  two  strong  crests,  each  terminated  by  a  spine.  Suborbital  crest  sharp,  composed  of  3 
nearly  equal  pointed  spines.  Posterior  extremity  of  the  maxillary  extending  about  to  the 
vertical  from  the  posterior  limb  of  the  orbit.  Tongue  free.  Teeth  in  broad  bauds  upon  the 
jaws,  longest  in  the  middle.     Vomerine  teeth  in  the  form  of  a  A.  with  wide  angle. 

Dorsal  flu  planted  far  back,  not  far  in  front  of  the  axil  of  the  pectorals.  The  base  of 
the  spinous  dorsal  is  nearly  one  third  as  long  as  the  body;  its  second  spine  is  much  the 
longest,  slender,  recurved,  its  length  about  twice  that  of  the  fourth  spine,  which  is  about 
equal  to  the  twelfth  and  twice  as  long  as  the  first.  The  spines  followingthe  fourth  decrease 
in  very  slow  and  gradual  gradation  to  the  eleventh,  the  seventh  to  the  eleventh  inclusive 
being  nearly  equal;  the  third  is  midway  in  length  between  the  secoud  and  the  fourth;  the 
.soft  dorsal  is  as  high  as  the  second  spine. 

The  origin  of  the  anal  is  in  the  vertical  from  that  of  the  second  dorsal:  its  end  iu  the 
vertical  from  the  preantepcnultimate  dorsal  ray,  its  first  spine  is  similar  in  size  and  shape 
to  the  first  of  the  dorsal;  its  second  to  the  fourth  of  the  dorsal,  though  stouter;  its  third  to 
the  fifth  of  the  dorsal.  The  base  of  the  pectoral  is  rather  narrow,  its  width  about  equal  to 
the  length  ot  the  snout.  Its  rays  are  apparently  all  simple,  the  middle  ones  the  longest 
and  nearly  as  long  as  the  longest  dorsal  spine,  and  extending  to  the  vertical  from  the  origin 
of  the  anal.    The  tips  of  all  the  rays  are  free,  those  of  the  middle  ones  most  so. 


DISCUSSION    OF    SPECIES    AND    THEIR    DISTRIBUTION.  255 

The  anal  is  inserted  under  bhe  axil  of  the  pectoral,  its  single  spine  slender  and  longer 
than  the  fourth  of  the  dorsal,  its  longest  rays  exceeding  those  of  the  second  dorsal,  and 
when  extended  backwards  passing  far  beyond  the  vent  and  almost  to  the  anal. 

The  lateral  line  is  almosl  straight,  and  (as  shown  in  the  figure)  has  36  to  38  tubes. 
This  corresponds  closely  to  Sauvage's  account;  he  records  12  scales  above  and  29  below  the 
lateral  line. 

Scales  broad,  with  three  or  lour  rows  of  strong  spines  upon  their  posterior  limb.  Color, 
body  reddish  yellow  with  numerous  black  blotches  on  each  side  of  the  lateral  line;  black- 
ish on  the  back  and  on  the  head.     Dorsal  and  caudal  spotted  with  black,  other  litis  light.

This  species,  described  by  Vaillant  from  the  Canaries,  was  obtained  off  those  islands 
by  Webb  and  Berthelot,  who  record  that  it  lives  at  a  depth  of  250  fathoms,  in  company 
with  Sebastes  imperialis.  It  is  called  by  the  Canary  fishermen  Rascazio  de  fuera,  while  its 
companion  is  the  Riibio  Colorado.    This  species  is  closely  related  to  1'.  Kuhlii.

strong  spine  in  the  axil  of  the  pectoral.  The  extremity  of  the  maxillary  extending  almost 
to  the  vertical  from  the  posterior  margin  of  the  orbit.  A  suborbital  horizontal  crest,  with 
2  feeble  spines  at  its  posterior  end.  The  maxillary,  the  lower  part  of  the  preopereulum, 
and  the  under  part  of  the  mandible  scaleless.  The  first  anal  spine  short,  stout,  its  length 
about  half  that  of  the  second  anal  spine,  which  is  nearly  as  long  as  the  soft  rays  of  the  fin.

The  type  of  this  species  was  brought  from  the  Canaries  by  Webb  and  Berthelot,  and 
was  18  centimeters  in  length.  It  is  to  all  appearances  a  deep-sea  form,  and  very  closely 
related  to  /'.  Bathbuni,  which  follows.

the  head  (28  millimeters)  equals  the  length  of  the  middle  caudal  rays.  The  width  of  the 
iuterorbital  area  (5  millimeters)  is  one-fourth  of  the  iuterorbital  part  of  the  head;  it  is  not 
very  deeply  concave  and  has  a  few  scales.  The  top  of  the  snout,  also,  is  fully  provided  with 
scales.  The  length  of  the  eye  (13  millimeters)  is  one-half  the  length  of  the  mandible.  The 
length  of  the  snout  (13  millimeters)  is  equal  to  that  of  the  eye.  The  maxilla  extends  nearly  to 
the  vertical  from  the  posterior  margin  of  the  eye;  its  length  (23  millimeters)  is  contained  i'J 
times  in  that  of  the  head  and  equals  one-half  the  greatest  height  of  the  body.  The  man- 
dible reaches  beyond  the  vertical  from  the  posterior  margin  of  the  eye,  its  length  (26  milli- 
meters) equaling  that  of  the  postorbital  part  of  the  head  and  twice  the  length  of  the  eye. 
Eight  developed  gill-rakers  below  the  angle  and  5  rudiments,  2  above  the  angle  and  5 
rudiments.  The  gill-rakers  are  very  slightly  expanded  at  the  end  and  the  longest  is  a  little 
more  than  2  millimeters  in  length.  Pseudobranchise  well  developed.  Teeth  in  villiform 
bands  in  the  jaws  and  on  the  vomer  aud  palate.  A  naked  space  at  the  symphysis  of  the 
inter inaxillaries.  The  distance  of  the  anterior  nostril  from  the  front  of  the  eye  equals  the 
distance  from  its  fellow  of  the  opposite  side:  it  is  in  a  tube  which  has  an  elongated  narrow 
extension  behind,  ending  in  two  or  three  small  filaments.  The  posterior  nostril  is  scarcely 
tubular  aud  is  placed  close  to  the  anterior.  A  pair  of  recurved  spines  on  the  preorbital.  a 
pair  between  the  nostrils,  four  spines  forming  the  suborbital  carina,  four  spines  on  the 
border  of  the  preoperculum,  the  uppermost  with  a  supplementary  spine  at  its  base.  The 
first  and  third  spines  larger  thau  the  others.  A  pair  of  compressed  flat  spines  on  the  oper- 
culum; a  pair  of  spines  at  the  front  of  the  orbit  above  and  a  pair  above  the  orbit  on  each 
side  posteriorly.  A  spine  on  each  side  of  the  vertex,  and  a  pair  on  each  side  of  the  nape. 
A  single  posterior  spine  on  each  side  and  two  humeral  spines. 

A  very  short  and  slender  filament  above  the  orbit  m  front,  a  Large  supraoecipital  fila- 
ment, which  expands  at  the  top  into  a  semi-leaf-like  tip.  A  small  slender  filament  between 
the  nuchal  spines,  a  combined  filament  behind  the  lower  preorbital  spine.  The  length  of 
the  longest  supraoecipital  filament  (19  millimeters)  is  about  two  thirds  the  length  of  the  eye. 

The  head  is  entirely  scaly  above  with  an  expansion  of  the  integument  covering  the 
supramaxilla. 

The  distance  of  the  spinous  dorsal  from  the  tip  of  the  snout  (45  millimeters)  is  con- 
tained 25}  times  in  the  standard  length,  and  is  equal  to  the  length  of  the  base  of  the  spinous 
dorsal.  The  length  of  the  first  spine  (9  millimeters)  is  one  half  that  of  the  second  spine, 
(18  millimeters);  I  he  length  of  the  third  and  longest  spine  (21  millimeters),  equal  to  the 
length  of  the  upper  jaw.  The  length  of  the  penultimate  spine  (12  millimeters),  equal  to 
one  half  the  length  of  the  upper  jaw.  The  length  of  the  last  spine  (13  millimeters)  is  equal 
to  that  of  the  eye.  The  length  of  the  base  of  the  soft  dorsal  (30  millimeters)  is  one-fourth  of 
the  standard  length.  The  length  of  the  third  and  longest  ray  (20  millimeters)  is  one-sixth 
of  the  standard  length.  The  length  of  the  middle  caudal  ray  (28  millimeters)  is  contained 
4£  times  in  the  standard  length.  The  tail  is  nearly  truncate  when  expanded.  The  anal 
origin  is  under  the  second  ray  of  the  dorsal.  The  length  of  the  anal  base  (16  millimeters) 
equals  two-thirds  the  length  of  the  upper  jaw.  The  length  of  the  first  spine  (9  millimeters) 
is  three-fourths  the  length  of  the  eye;  the  length  of  the  second  spine  (23  millimeters) 
equals  the  length  of  the  maxilla;  the  length  of  the  third  (1!)  millimeters)  is  about  twice  that 
of  the  first.  The  length  of  the  longest  ray  (23mm.)  equals  that  of  the  second  spine.  The 
last  ray  (15  millimeters)  is  nearly  equal  to  the  base  of  the  fin.  The  vent  is  under  the  tenth 
spine  of  the  dorsal.  The  pectoral  rays  are  all  simple;  the  tenth  is  the  longest,  its  length 
(30  millimeters)  equal  to  one-fourth  of  the  standard  length.  The  fin  reaches  slightly  beyond 
the  vent  when  extended,  but  does  not  reach  to  above  the  origin  of  the  anal;  the  ventral 
reaches  to  the  vent;  the  length  of  its  spine  (17  millimeters)  is  about  one-third  the  length  of 
the  head.  The  length  of  the  second  ventral  ray  (27  millimeters)  is  a  little  more  than  one- 
half  the  length  of  the  head.

This  species  is  closely  related  to  /'.  canariensis,  but  may  l>e  distinguished  by  the 
greater  number  of  scales  in  the  lateral  line,  by  the  shorter  pectorals,  the  ventrals,  which 
when  extended  reach  to  the  line  of  the  vent  only.  by  the  more  advanced  position  of  the 
anal,  the  termination  of  whose  base  is  under  the  base  of  the  antepenultimate  dorsal  raj  ; 
by  the  greater  length  of  the  second  anal  spine,  which  is  longer  than  the  third,  and  nearly 
three  times  as  long  as  the  first;  by  the  character  of  the  suborbital  crest,  which  is  high  and 
sharp  ami  has  its  surface  notched  into  three  portions,  so  that  it  appears  to  be  composed  of 
three  long  depressed  spines;  by  the  presence  of  lacuna-  in  the  occipital  region;  by  the 
more  advanced  position  of  the  pectoral,  whose  base  is  almost  hidden  under  the  branchios- 
tegal  membrane,  its  anterior  spine  being  close  to  the  edge  of  the  opercular  flap. 

The  contour  of  the  dorsal  is  much  the  same,  save  that  the  spines  are  more  slender  and 
the  notch  less  deep,  the  eleventh  spine  being  equal  to  the  tenth,  and  not  much  shorter  than 
the  ninth. 

Pontinus  Rathbuni  is  dedicated  to  Mr.  Richard  Iiathbun,  chief  of  the  Division  of  Scien- 
tific Inquiry  in  the  U.  S.  Fish  Commission,  in  recognition  of  his  important  contributions  to 
marine  zoology. 

PONTINUS  MACROLEPIS,  Goode  and  Bean,  n.  s.     (Figure  247.) 

A Pontinus having  pectoral  rays  all  simple  as  in  P.longispinis,  I'.  Kuhlii,  and  /'.  castor, 
and  larger  sealed  than  either  of  those.  We  have  compared  it  with  Pontinus  castor  of  Poey, 
and  while  it  belongs  to  the  same  genus  it  is  a  much  larger  scaled  species  than  Poey's  and 
the  supraoccipital  filaments  are  much  less  developed.  The  greatest  depth  of  the  body  (30 
millimeters)  is  about  one-third  of  the  standard  length;  the  least  height  of  the  tail  (8  milli- 
meters) equals  the  length  of  the  snout.  The  length  of  the  head  (41  millimeters)  is  equal  to 
one-half  the  total  length  to  the  end  of  the  dorsal.  The  greatest  width  of  the  head  (21  milli- 
meters) is  about  one  half  its  greatest  length.  The  width  of  the  interorbital  area  (4  milli- 
meters) is  about  one-half  the  length  of  the  snout.  The  interorbital  region  is  deeply  concave 
and  scaleless;  top  of  snout  also  scaleless.  The  length  of  the  eye  (13i  millimeters)  is  about 
one-third  the  length  of  the  head.  The  length  of  the  postorbital  part  of  the  head  to  the  end 
of  the  opercular  flap  (L9  millimeters)  equals  one-half  the  distance  from  the  tip  of  the  snout 
to  the  origin  of  the  spinous  dorsal.  The  maxilla  reaches  beyond  the  vertical  from  the 
middle  of  the  eye  and  the  mandible  to  below  the  end  of  the  eye.  The  length  of  the  maxilla 
(L'O  millimeters)  is  one-half  the  length  of  the  head.  The  length  of  the  mandible  (21  niilli 
meters)  equals  the  length  of  the  ventral.  Four  rudiments  and  2  developed  gill-rakers 
.  above  the  angle;  9  developed  below  the  angle.  The*developed  gill  rakers  have  alittle  knob

backward.  A  very  short  filament  above  the  orbit  in  front  and  another  one  behind,  whose 
length  (4  millimemeters)  is  about  one-third  that  of  the  eye.  The  head  is  entirely  scaly 
with  the  exception  of  the  top  of  the  snout,  and  the  integument  covering  the  supramaxilla 
and  the  gill  rakers  has  the  same  structure,  The  anterior  nostrils  are  tabular,  the  tube 
produced  behind  into  a  thin  narrow  nap;  the  anterior  nostril  is  at  a  distance  from  the  eye 
equal  to  the  interorbital  width.  The  posterior  nostril  is  not  tabular.  The  distance  of  the 
dorsal  from  the  tip  of  the  snout  (3G  millimeters)  is  twice  the  length  of  the  maxilla.  The 
length  of  the  first  spine  (10  millimeters)  is  about  two- thirds  the  length  of  the  the  second  (14 
millimeters),  the  third  and  longest  spine  (1C  millimeters)  is  one  half  as  long  as  the  head 
without  the  snout.  The  penultimate  spine  (8  millimeters)  is  nearly  as  long  as  the  first,  and 
the  last  spine  (10  millimeters)  is  about  one-half  the  length  of  the  upper  jaw.  The  longest 
ray  of  the  dorsal  (12  millimeters)  equals  one-third  of  the  distance  from  tip  of  snout  to  dorsal. 

The  length  of  the  middle  caudal  rays  (20  milimeters)  is  about  one-half  the  length  of  the 
head.  The  caudal  is  almost  truncated  behind.  The  anal  originates  under  the  second  ray 
of  the  dorsal;  the  length  of  its  base  (10  millimeters)  is  one  quarter  the  length  of  the  head. 
The  length  of  the  first  spine  (7  millimeters)  is  about  two-thirds  the  length  of  the  anal  base; 
the  leugth  of  the  second  (17  millimeters)  is  about  one-fifth  of  the  standard  length;  length 
of  third  spine  (13  millimeters)  is  about  equal  to  that  of  the  eye.  The  longest  ray  (10  mil- 
limeters) is  equal  to  the  longest  spine  of  the  dorsal. 

The  longest  ray  of  the  pectoral  (25  millimeters)  equals  the  distance  from  the  vent  to 
the  origin  of  the  ventral.  Pectoral  when  extended  reaches  to  the  vent  or  to  the  vertical 
from  the  penultimate  dorsal  spine.  The  ventral  origin  is  under  the  base  of  the  pectoral. 
The  fin  reaches  to  the  vent,  its  length  (22  millimeters)  a  little  greater  than  that  of  the 
mandible.  There  are  about  0  lows  of  scales,  counted  obliquely,  from  the  origin  of  the 
dorsal  to  the  lateral  line  and  about  1 0  below  the  line.  There  are  about  22  tubes  in  the 
lateral  line.

The  colors  of  the  alcoholic  specimens  have  faded  out,  The  type  is  now  a  very  light 
orange;  fins  all  pale.  There  are  faint  traces  of  the  existence  of  dusky  blotches  along  the 
back  in  life. 

The  colors  of  the  fresh  specimen  were  as  follows:  Uniform  rosy  intermingled  with 
pearly  white;  the  light  areas  most  conspicuous  on  the  fins.  Anterior  part  of  anal  more 
intensely  colored  than  any  other  part  of  the  fish.  Cephalic  tentacles  pale;  the  posterior 
supraocular  pair  with  a  little  band  of  rose  a  little  below  the  middle  of  the  height.  Pupil 
an  intense  blue.  Iris  golden  above  and  below,  overlaid  with  rosy,  greenish  golden  an- 
teriorly and  posteriorly.  Belly  and  throat  pearly  white.  The  light  areas  on  the  caudal 
simulate  bands. 

The  type  of  the  description  is  a  single  small  individual  measuring  88  millimeters  to

PONTINUS  LONGISPINIS,  Goode  aud  Bean,   n.  s.     (Figure  246.) 

The  peculiar  form  of  the  spinous  dorsal,  noticeably  in  P.  Kuhlii,  is  quite  marked  in 
our  new  species — that  is  to  say,  the  third  spine  is  longer  than  the  fourth,  and  much  longer 
than  the  first  and  second.  The  gill-rakers  also  are  stout,  rather  short,  and  not  numerous, 
while  the  pectoral  rays  are  all  small.  The  species  is  not  so  deep-bodied  as  <S'.  Kuhlii,  the 
greatest  depth  of  the  body  (40  millimeters)  being  a  little  less  than  one-third  of  the  stand- 
ard leugth.  The  least  height  of  the  tail  (12  millimeters)  is  one-fourth  of  the  length  of  the 
head.  The  leugth  of  the  head  (50  millimeters)  is  about  two  fifths  of  the  standard  length; 
greatest  width  (27  millimeters)  is  a  little  more  than  one-half  its  length.  The  width  of  the 
interorbital  area  (7  millimeters)  is  one-half  the  length  of  the  eye,  which  is  about  equal 
to  the  length  of  the  snout.  The  length  of  the  eye  (15  millimeters)  is  contained  3J 
times  in  that  of  the  head,  or  li  times  in  the  length  of  the  postorbital  part  of  the 
head.    The  maxilla  reaches  to  below  the  middle  of  the  eye;  its  leugth  (23  millimeters)  is

one-half  the  distance  from  the  tip  of  the  snout  to  the  spinous  dorsal.  The  mandible 
extends  slightly  farther  back  than  the  maxilla,  its  length  (26  millimeters]  about  one- 
half  the  length  of  the  head.  Teeth  in  the  jaws  in  villiforin  bands.  At  the  symphysis  of 
the  interuiaxillaiics  there  is  a  slight  interspace  separating  the  two  enlarged  club-shaped 
ends  of  the  bone.    The  vomerine  patch  in  a  very  narrow  triangular  band ;  the  palatine  bands 

also   are    very    narrow :  iiseinloliranelii;e    well   developed;   12  developed    gill-rakers   on    tlie 

anterior  arch,  of  which  9  are  below  the  angle  besides  the  rudiments.  A  pair  of  spines 
between  the  anterior  nostrils;  a  pair  of  spines  on  the  front  of  the  preorbital;  three  forming 
a  ridge  across  the  cheek;  4  on  the  preoperculum,  of  which  the  one  at  the  middle  of  the 
border  is  the  largest;  2  on  the  operculum;  a  pair  of  spines  above  the  front  of  the  orbit;  '! 
small  supraorbitals,  2  nuchal,  1  postorbital,  and  2  at  the  origin  of  the  lateral  line; 
no  filaments  about  the  head.  Cheeks  and  opercles  scaly.  Scales  on  the  nape  and  on  the 
top  of  the  snout.  The  sides  of  the  snout  are  naked,  and  there  are  no  scales  on  the  integu 
nient  covering  the  maxilla.  The  ridges  of  the  spines  of  the  head  and  of  the  scales  are 
exactly  the  same  as  in  /'.  Kuhlii  and  the  gill-rakers  have  the  same  structure.  The  anterior 
nostrils  are  tubular,  distant  from  the  eye  about  one-third  the  eye's  diameter,  and  its  dis- 
tance from  its  fellow  of  the  opposite  side  (7  millimeters)  is  nearly  one  half  the  length  of  t  he 
eye.  The  spinous  dorsal  originates  a  little  in  front  of  the  base  of  the  pectoral;  its  dis- 
tance from  the  tip  of  the  snout  is  twice  the  length  of  the  maxilla.  The  length  of  the  first 
spine  (9  millimeters)  is  one-half  that  of  the  fourth  spine;  the  length  of  the  second  spine 
( 13  millimeters)  is  scarcely  more  than  one-half  the  length  of  the  third  spine  (25  millimeters). 
The  fourth  spine  is  considerably  shorter  than  the  third,  and  the  spines  gradually  decrease 
in  length,  so  that  the  eleventh  is  a  little  shorter  than  the  second.  The  length  of  the  twelfth 
spine  (10  millimeters)  is  about  equal  to  the  length  of  the  snout.  The  length  of  the  longest 
ray  of  the  second  dorsal  (19  millimeters)  is  nearly  one-half  of  the  base  of  the  spinous  dor- 
sal. The  caudal  is  very  slightly  emargiuate;  the  length  of  the  middle  rays  (31  millimeters) 
is  about  one-fourth  of  the  standard  length.  The  anal  origin  is  under  the  first  ray  of  the 
soft  dorsal;  the  length  of  the  base  of  the  fin  (16  millimeters)  is  nearly  one-third  of  the 
length  of  the  head.  The  length  of  the  first  spine  (8  millimeters)  is  nearly  one-third  that  of 
the  second  spine  (20  millimeters).  The  length  of  the  third  spine  (26  millimeters)  is  2i  times 
that  of  the  first.  The  length  of  the  longest  ray  (22  millimeters)  is  li  times  that  of  the  last 
ray  (15  millimeters).  The  pectoral  origin  is  under  the  interspace  between  the  second  and 
third  dorsal  spines;  the  fin  reaches,  when  extended,  almost  to  the  end  of  the  spinous  dorsal 
or  to  the  thirteenth  pore  of  the  lateral  liue.  The  ventral  is  under  the  pectoral;  the  length 
of  its  spine  (22  millimeters)  nearly  equal  to  the  length  of  the  maxilla.  The  fin  reaches 
about  tc  the  vent  when  extended;  the  length  of  the  longest  ray  (27  millimeters)  is  a 
little  more  than  one-half  the  length  of  the  head.  The  vent  is  under  the  ninth  spine  of 
the  dorsal;  its  distance  from  the  origin  of  the  anal  (9  millimeters)  is  equal  to  one-third  of 
its  distance  from  the  origin  of  the  ventral.

A  Sebastes  with  compressed  body,  elevated  dorsal  outline  and  straightish  ventral  outline. 

Top  of  head  scaly:  interorbital  space  concave,  with  two  low  ridges;  cranial  ridges 
moderate,  rather  low  and  sharp;  preocular,  supraocular,  postocular,  tympanic  and  occipital 
ridges  present,  the  latter  with  divergent  tips;  suprascapular  spines  sharp  and  prominent, 
opercular  spines  long  and  sharp,  subopercular  spine  prominent;  preopercular  spines  slender 
and  sharp,  the  second  longest.  Suborbital  stay  not  reaching  preopercle;  preorbital  narrow, 
with  two  spines. 

Eye  very  large,  more  than  twice  as  long  as  interorbital  space,  and  one  third  as  long  as 
head.  Mouth  large,  oblique,  with  broad  maxillary,  which  reaches  middle  of  eye;  tip  of 
lower  jaw  much  projecting,  with  a  conspicuous  knob  at  symphysis;  mandible  and  maxillary 
scaly. 

Pseudobranchire  very  large;  gill  rakers  long,  stiff,  and  strong. 

Dorsal  tin  deeply  emarginate,  with  sharp  spines,  the  longest  about  equal  to  diameter  of 
eye;  soft  rays  higher  than  the  spines.  Caudal  narrow,  moderately  forked.  Anal  spines 
moderate,  graduated,  the  second  a  little  shorter  than  eye.  Pectoral  with  narrow  base  and 
rather  long,  reaching  vertical  from  vent.  Ventral  reaching  to  vent.  Scales  small,  irregular, 
not  strongly  ctenoid;  about  40  tubes  in  the  lateral  line,  and  about  8.j  scales  in  longitudinal

This  well  known  form  is  abundant  between  the  hundred  fathoms  line  off  the  south 
coast  of  New  England,  and  has  been  found  as  low  as  180  fathoms.  It  breeds  abundantly  in 
late  summer  at  these  depths,  and  there  is  no  reason  to  believe  that  the  young  rise  to  the 
surface.  The  fry  were  caught  by  the  bushel  in  the  trawl  net,  and  were  eaten  on  the  Fish 
Hawk, cooked  after  the  manner  of  "whitebait," 


DISCUSSION   OF   SPF.ciF.s    AND    Tlll.IR    DISTRIBUTION.  261 

The  species  was  known  from  the  western  Atlantic  as  early  as  the  time  of  Cuvier,  who 
had  specimens  sent  from  Miquelon,  Newfoundland,  by  M.  de  la  Pilaie.  It  was,  however, 
originally  described  from  Norway  by  Linnaeus,  and  seems  to  have  been  mentioned  by  Olaf 
sen  about  Iceland  as  early  as  1774.  Linnaeus  ascribed  it  also  to  the  Mediterranean,  but,  as 
Cuvier  has  shown,  it  is  very  evident  that  the  southern  fish  which  he  had  in  mind  was  Ser 
ranus  scriba  (compare  Systema  Natures,  L2th  edition,  pp.  483  and  486).  [t  has  never  been 
found  south  of  the  British  Channel,  and  the  figure  by  Day  was  obtained  by  him  from 
I'treeht  or  Leyden,  but  he  does  not  say  whether  or  not  it  was  from  Dutch  waters.  Day 
gives  a  number  of  Idealities  of  its  capture  about  the  British  Isles,  but  it  is  rare  south  of 
Faroe  Islands. 

It  occurs  on  the  southwest  coast  of  Spitzbergen  (Malmgren,  loc.  eit.),  and  on  the  Norwe- 
gian coast  it  is  found  everywhere  from  Christ iania  around  to  the  Varanger  Fiord.  It  also 
occurs  in  Greenland,  and  from  Labrador,  as  a  shore  form,  as  far  south  as  .Maine  (See  Esses 
Fishes),  and  in  deeper  water,  as  shown  iu  the  accompanying  list,  as  far  south  as  39°  48.'  The 
Norwegian  expedition  obtained  it  as  deep  as  147  fathoms,  and  American  vessels  down 
to  179. 

Specimens  of  this  species  have  also  been  found  by  the  steamer  Albatross  in  the  follow-

This  form  is  recognized  by  certain  Scandinavian  zoologists  and  by  Giinther  in  his  later 
writings  as  a  distinct  species.  No  very  salient  characters  have  been  pointed  out,  save  that 
it  is  smaller,  has  a  higher  body,  and  longer  head,  a  narrower  interorbital  space,  longer 
pectoral  and  ventral  tins,  and  an  additional  soft  ray  in  dorsal  and  anal.  Jordan  describes 
its  general  color  as  brownish  red,  somewhat  mottled,  with  a  blackish  blotch  on  the  opercle, 
and  some  other  brownish  spots  ou  the  body,  as  if  he  had  identified  this  form  from  American 
waters.  All  those  we  have  seen  arc  more  like  the  »V.  ririjinrns  type,  Giinther  says  that  it  is 
found  in  Scandinavian  waters  at  a  depth  of  300  fathoms.  It  is  generally  understood  to  be 
more  littoral  iu  its  habits  than  8.  marinus. 

SEBASTOLOBUS,  Gill. 

Sebastolobus,  Gill,  Report,  Smithsonian  Institution.  18S0  (1881),  375. 

Scorpamids  with  vertebra'  as  in  the  typical  species  of  Sebastes  and  characterized 
by  the  pectorals  having  a  wide  base,  produced  back-wards  near  the  upper  margin,  and  not 
medially,  while  the  lower  rays  are  thickened  aud  extend  much  beyond  the  rays  next  above

ia  a  linguiforin  lobe.    The  ventrals  are  directly  under  the  axils  of  the  pectorals,  with  the 
outer  rays  produced,  thick  and  branched. 

This  genus  has  as  yet  been  found  only  in  the  Pacific.  The  type  is  Sebastolobus  macro- 
ehir  (Giinther)  Gill,  (Challenger  Report,  i,  1880,  part  VI,  65,  PL  xxvii),  obtained  by  the 
Challenger  off  Inosiina,  at  a  depth  of  34.5  fathoms.  Another  species,  8.  alascanus,  Bean 
(Proc.  U.  S.  Nat.  Mus.,  xiii,  1890,  44),  was  obtained  by  the  Albatross  at  station  2853,  off 
Trinity  Islands,  Alaska,  in  N.  Lat.  56°,  W.  Lou.  154°,  at  a  depth  of  159  fathoms. 

SEBASTODES,  Gill. 
Sebastodes,  Gill,  Proc.  Acad.  Nat.  Sci.  Phila.,  1863,  207. 

Scorpsenids  with  the  dorsal  continuous,  though  somewhat  notched,  and  with  thirteen 
spines  in  the  dorsal  and  nine  rays  in  the  anal.  Skull  thick  and  cranial  ridges  weak. 
Lower  jaw  much  projecting.  Teeth  in  villiform  bands  on  jaws,  vomer,  and  palatines. 
Scales  small,  ninety  to  one  hundred  in  the  lateral  line. 

This  genus  is  represented  by  a  single  species,  S.  paueispinis,  (Ayres),  Jordan  and  Gil- 
bert, found  on  the  coast  of  California  "  in  rather  deep  water.''  Deep-sea  representatives  of 
the  genus  should  be  looked  for  on  our  Northwest  coast. 

SEBASTICHTHYS,  Gill. 
Sebastichthys,  Gill,  Proc.  Acad.  Nat.  Sci.  Phila.,  1863,  207. 

Scorpsenids  with  the  dorsal  continuous,  though  somewhat  notched,  and  with  thirteen 
spines  in  the  dorsal  and  live  to  nine  in  the  anal.  Skull  thick  and  cranial  ridges  weak. 
Lower  jaw  projecting  but  slightly.  Teeth  iu  villiform  bauds  on  jaws,  vomer,  and  palatines. 
Scales  moderate,  forty-five  to  eighty  in  the  lateral  Mne. 

This  genus  is  represented  on  the  Northwest  coast  and  adjacent  deep  waters  by  forty 
or  more  species,  nine  or  ten  of  these  having  been  described  as  new  by  Gilbert,*  from  the 
bathybial  fauna  explored  by  the  Albatross  in  1888.  These  occur  outside  the  100-fathom 
line,  and  to  as  great  a  depth  as  266  fathoms.  As  might  have  been  expected,  the  genus 
of  bottom-living  lishes  most  abundant  in  species  and  numbers  along  the  shores  of  this  coast, 
has  contributed  the  largest  quota  to  the  inshore  deep-water  fauna  of  the  adjacent  ocean.

Setarches,  Johnson,  Proc.  Zool,  Soc.  London,  1862,  176.— -Jordan  and   Gilbert,  Ball,  xvi,  U.  S.  N.  M.,  682. 

Scorpsenids  with  head  and  body  compressed,  the  head  flat  between  the  eyes,  with  sev- 
eral low  ridges.  Head  scaleless,  its  bones  cavernous.  No  transverse  groove  on  the  occiput. 
Preoperculum  and  operculum  strongly  armed  with  straight,  long  spines.  Eye  moderate, 
near  but  not  touching  the  profile.  Mouth  terminal,  broad,  somewhat  oblique,  the  posterior 
edge  of  the  maxillary  extending  to  opposite  the  posterior  part  of  the  eye,  and  much 
expanded.  Lower  jaw  somewhat  projecting,  with  kuob  at  symphysis  received  in  rostral 
notch.     Villiform  teeth  in  jaws,  on  vomer  and  palatines. 

Opercles  scaly.  Scales  cycloid,  moderate.  Lateral  line  a  broad,  scaleless  groove,  with 
a  series  of  skinny  tubes.     No  lacinise. 

Dorsal  fin  deeply  notched,  so  as  to  appear  in  two  portions;  dorsal  spines  10-1,  the  soft 
portion  of  the  fin  shorter,  and  with  rays  fewer  than  spines.  Anal  with  3  strong  spines 
inserted  under  the  end  of  the  dorsal.  Pectoral  fin  broad  and  long,  with  20  or  more  rays, 
of  which  a  considerable  number  of  the  medial  ones  are  branched.  Branchiostegals  6  or  7. 
Pyloric  appendages  few.    No  air  bladder. 

The  type  is  Setarches  GHintheri  (Johnson),  from  Madeira,  undoubtedly  from  deep  water, 
since  only  one  specimen  appears  to  have  ever  been  taken.  The  genus  Lioscorpius  (Giiuther) 
can  scarcely  be  distinguished  from  Setarches.

SETAECHES  GUNTHERI,  Johnson. 

Setarches  Giinther*,  JOHNSON,  Proo.  Zoi'il.  Soe.,  London,  1862,  177.  pi.  xxm. 

A  Setarches  having  body  and  head  elongate;  the  height  of  the  body  over  ventrals

length  of  body  (without  tail);  length  of  head  2i  in  length  of  body. 

Head  not  much  compressed.  Width  of  interorbital  space  1}  times  the  diameter  of  the 
eye.  which  is  somewhat  below  the  profile.  No  conspicuous  ridges  upon  the  top  of  the  head, 
but  two  low,  flat,  occipital  spines.  Snout  If  times  as  long  as  the  diameter  of  the  eye. 
Mouth  wide,  somewhat  oblique;  maxillary  with  a  much  expanded  posterior  extremity,  reach- 
ing nearly  to  vertical  from  posterior  margin  of  orbit.  Lower  jaw  projecting,  with  a  strong, 
bony  tubercle  at  its  symphysis.  Sides  of  head  strongly  armed.  Three  slender,  sharp, 
closely  set,  parallel  spines,  of  which  the  middle  one  is  slightly  the  longest,  at  the  angle  of 
the  suboperculuni,  and  2  smaller  spines  on  its  lower  limb.  Two  long,  strong  spines  upon 
the  opercular  Hap.  Two  strong,  retrorse  spines  upon  the  preorbital,  their  points  projecting 
down  over  the  maxillary. 

Head  scaleless,  except  upon  the  opercle.  Scales  small,  cycloid,  there  being  about  86 
in  the  longitudinal  series.  The  lateral  line  passing  with  a  broad,  gentle  curve  under  the 
notch  between  the  two  dorsals,  from  a  point  very  near  the  dorsal  profile  to  the  middle  of  the 
base  of  the  caudal.  It  has  no  scales,  but  conspicuous  skinny  tubes,  of  which  the  figure 
indicates  28  to  30.  Dorsal  insertion  in  advance  of  that  of  pectoral,  with  the  first  spine  about 
half  as  long  as  the  diameter  of  the  eye,  and  separated  somewhat  from  the  second,  which  is 
the  longest,  and  more  than  twice  the  eye;  followed  by  others  which  gradually  and  irregu- 
larly decrease  in  length  to  the  tenth,  which  is  about  equal  to  the  first,  which  is  followed 
behind  the  notch  by  a  slender  one  as  long  as  the  sixth.  Nine  soft  dorsal  rays,  the  longest 
as  long  as  the  first  dorsal  spine,  but  the  length  of  the  base  of  this  tin  is  less  than  half  that 
of  the  spinous  dorsal.  Anal  inserted  under  the  posterior  portion  of  soft  dorsal,  with  3 
spines  and  5  rays.  Ventral  under  the  first  dorsal  spine,  its  longest  rays  equal  to  the  exter- 
nal caudal  rays.  Pectoral  very  broad  at  its  base,  which  occupies  nearly  half  the  height 
of  the  body,  and  with  22  rays,  of  which  the  first  two  and  the  last  five  are  simple,  the  re- 
mainder branched:  the  upper  branched  rays  tire  very  long,  one  third  as  long  as  the  body,  and 
reach  beyond  the  origin  of  the  anal.  Caudal  truncate,  its  middle  rays  as  long  as  the  soft 
dorsal. 

Color,  uniform  pink  red.  minutely  dotted  with  black. 

Radial  formula:  D.  X-xi,  I,  9;  A.  in,  5;  P.  2  +  15+.-);  V.  I,  5;  C.  4+7  +  4. 

A  single  specimen,  !•  inches  long,  now  in  the  British  .Museum,  was  found  by  Johnson 
at  Madeira  and  named  in  honor  of  Dr.  Giinther.  The  depth  of  its  habitat  was  not  at 
that  time  observed,  but  from  what  is  known  of  the  habits  of  its  associates,  it  can  not  be 
doubted  thai  it  is  a  deep  sea  form. 

S.  fidjiensis,  Giinther,  was  obtained  by  the  Challenger  at  station  17."..  oil'  Matuku  in  the 
Fiji  Islands,  at  a  depth  of  315  fathoms,  a  single  specimen  .'1  inches  long.     It  is  shorter  than

8.  Giintheri,1  with  a  shorter  and  higher  dorsal,  a  shorter,  more  rounded  pectoral,  with  the 
preorbital  spines  aatrorse  and  the  preopercular  spines  slenderer,  more  uniform  in  size,  more 
divergent,  and  four  in  number.  The  four  ridges  of  the  vertex  terminate  each  in  ;.  sharp 
spine,  visible  from  the  lateral  aspect. 

SETARCHES  PAEMATUS,  Goode.    (Figure  249.) 

Setarches  parmatus,  Goode,  Proc  U.  S.  N.  M.,  m,  480,  Feb.  16,  1881. — Goode  and  Bean,  Bull.  Mus.  Comp.

A  Setarches  having  head  and  body  short  and  somewhat  compressed;  the  height  of  the 
body  over  ventrals  greatest,  and  contained  about  2A  in  total  length  (without  caudal)  length 
of  head  2£  in  length  of  body. 

Head  somewhat  compressed.  Width  of  interorbital  area  equal  to  diameter  of  eye, 
which  is  somewhat  below  the  profile.  Ridges  on  top  of  head  low  and  inconspicuous;  two 
extending  to  the  occiput,  where  they  terminate  in  low,  flat  spines;  two  short  ones  over  the 
posterior  margin  of  orbit,  ending  in  spines  slightly  behind  the  orbit.  Snout  as  long  as  the 
orbit.  Mouth  wide,  somewhat  oblique;  maxillary  with  a  considerably  expanded  posterior 
extremity,  reaching  nearly  to  the  vertical  from  posterior  margin  of  orbit.  Lower  jaw 
scarcely  projecting,  and  without  prominent  knob  at  symphysis.  Sides  of  head  lightly 
armed,  there  being  four  slender,  elongate  spines  on  the  preoperculum;  the  edge  of  the  sub- 
orbital is  broadly  scalloped  with  two  points  projecting  in  downward  direction  opposite  the 
anterior  and  posterior  margin  of  the  orbit.  Spines  on  the  operculum  small  and  inconspic- 
uous. Two  slender  spines  upon  the  preorbital,  the  anterior  one  touching  the  opening  of 
the  mouth.  Head  scaleless  save  upon  the  operculum,  pre-  and  suboperculum.  Scales 
small,  cycloid,  each  with  several  concentric  furrows.  Lateral  line  broad,  scaleless,  with 
shinny  tubes,  of  which  there  appears  to  be  about  30  (an  exact  count  not  possible);  the 
lateralline  is  practically  concurrent  with  the  line  of  the  back.  Dorsal  insertion  in  advance 
of  that  of  pectoral;  the  first  spine  more  than  half  as  long  as  second,  and  equal  to  ninth; 
the  second  as  long  as  the  seventh;  the  third  and  fourth  about  equal,  and  a  little  longer 
than  the  maxillary;  the  fifth,  si  \th.  seventh  and  eighth  gradually  decreasing.  There  are 
12  spines  and  10  soft  rays,  the  tin  being  deeply  notched. 

The  type,  as  the  drawing  indicates,  is  somewhat  deformed,  owing  to  an  accident  in  life, 
but  a  comparison  with  the  other  related  species  enables  us  to  judge  very  nearly  of  what  its 
shape  must  have  been.  Anal  inserted  under  posterior  part  of  soft  dorsal,  with  3  spines 
and  5  rays,  the  longest  of  which — about  equal  to  the  last  spine — are  as  long  as  the 
second  dorsal.  Ventral  in  vertical  from  root  of  second  dorsal  spine,  with  1  spine  and 
5  rays,  its  tip  not  reaching  to  vent,  which  is  close  to  origin  of  anal.  Pectoral  broad  at 
its  base,  elongate,  some  of  its  median  rays  apparently  branched,  its  tip  extending  beyond 
the  origin  of  the  anal.

LIOSCORPIUS,   Gunther. 
LioBCorpius,  GONTHER,  Challenger  Report,  I.  Part  vi,  p.  40,  pi.  xvu,  rig.  C. 

Scorpsenids  with  head  and  body  compressed,  the  former  with  muciferous  cavities 
above,  and  with  scarcely  any  ridges  or  spines.  Occiput  without  groove,  naked.  Three 
strong  sharp  spines  upon  the  preoperculum  and  two  upon  the  opercular  flap.  The  mouth 
very  large,  the  snout  elongate,  thecurve  of  the  mouth  being  downward.  Orbit  encroaching 
upon  upper  outline  of  head.  Body  covered  with  small  scales,  and  with  a  wide,  naked  lat- 
eral line  with  about  28  skinny  tubes.  Dorsal  tins  separate;  the  first  low,  with  eight  or 
nine  spines,  the  first,  second,  and  third  evenly  graduated.  Pectoral  tin  long,  lanceolate,  with 
simple  rays.  Teeth  villiform  in  bands  in  the. jaws  and  ou  the  vomer  and  palatine  bones. 
Bran chios tegals  vn. 

The  type  of  this  genus  is  Lioscorpiiis  longiceps,  Gunther,  loc.  cit.,  pi.  xvn,  fig.  C,  which 
closely  resembles  Setarches  parmatm  in  form,  except  that  its  head  and  snout  are  longer, 
and  the  upper  jaw  curves  downward.  The  genus  seems  well  enough  separated  from 
Setarches  by  the  smooth,  grooveless  occiput  and  the  simple  character  of  the  rays  of  the 
pectoral.

Head  and  body  smooth,  scaleless,  covered  with  a  tough,  lax  skin.  The  length  of  the 
head  is  nearly  one-third  of  the  extreme  length  of  the  body,  including  the  caudal;  its 
greatest  height,  one  fourth  of  the  body  without  the  caudal.  The  greatest  width  of  the 
head  is  twice  the  length  of  the  maxilla.  The  distance  of  the  vent  from  the  insertion  of 
the  anal  equals  the  length  of  the  maxilla.    The  eye  is  close  to  the  dorsal  profile.    The

length  of  the  orbit  is  about  equal  to  that  of  the  snout,  and  is  contained  about  U  times  in 
the  greatest  length  of  the  head.  The  intermaxillary  is  long  and  slender,  its  length  con- 
tained slightly  more  than  3  times  in  the  distance  from  the  tip  of  the  snout  to  the  insertion 
of  the  first  dorsal  (34,  times  in  the  length  of  the  head).  The  maxilla  is  very  slender,  except 
in  its  posterior  third,  where  it  is  considerably  expanded.  The  mandible  is  very  stout,  pos 
teriorly  widened,  its  length  contained  nearly  24,  times  in  that  of  the  head.  Teeth  in  broad 
villiforni  bands  on  the  intermaxillary  and  the  mandible.  Two  short,  separate,  .similar 
bands  on  the  vomer.     None  on  the  palatines. 

Head  armed  with  blunt  spines,  as  in  ('.  microps. 

The  distance  of  the  dorsal  from  the  tip  of  the  snout  is  nearly  equal  to  one-third  of  the 
total  length,  caudal  included.     It  consists  of  ti  spines  and  17  rays. 

The  anal  fin  is  located  midway  between  the  tip  of  the  snout  and  the  end  of  the  caudal 
fin;  it  consists  of  L3  rays. 

The  length  of  the  upper  pectoral  rays  is  equal  to  that  of  the  postorbital  portion  of 
the  head.  The  pectoral  rays  diminish  rapidly  in  size,  the  lowest  being  exceedingly  short. 
The  number  of  rays  is  22.  The  distance  of  the  ventral  from  the  tip  of  the  snout  is  one- 
third  of  the  total  length  without  the  caudal.  The  length  of  the  free  portion  of  the  ventral 
equals  that  of  the  eye.    The  fin  consists  of  1  spine  and  3  rays. 

The  caudal  consists  of  10  developed  rays. 

Color  light  brown,  the  tins  somewhat  darker. 

Specimens  were  obtained  by  the  Blair  from  station  ccevi,  in  41°  32'  50"  X.  lat.,  65"  55'

Nat.  Mus..  712. 

A  species  with  body  thick,  subcylindrical  anteriorly,  rapidly  tapering  to  the  tail,  cov- 
ered with  a  thick  lax  integument;  its  greatest  height  (.25)  equals  the  length  of  the  head 
and  is  one-fourth  of  the  total  length  of  the  body  without  caudal. 

Head  somewhat  tumescent  at  the  nape;  its  height  (over  the  ventral  disk  and  eyes)  con- 
tained something  over  six  times  iu  the  length  of  the  body;  its  greatest  width  (.18)  very 
Brightly  greater  and  equaling  twice  the  width  of  the  ventral  disk.  Snout  broad,  with  promi- 
nent vertical  profile;  its  length  about  one-fourth  that  of  the  head.  Cleft  of  the  mouth  hori- 
zontal, not  extending  to  perpendicular  from  the  anterior  margin  of  the  orbit.  Lips  covered 
with  thick  lax  skin,  the  upper  jaw  extending  beyond  the  lower. 

Length  of  the  upper  jaw  about  one-third  of  length  of  head;  that  of  mandible  slightly 
greater  than  length  of  ventral  disk.  Bach  jaw  armed  with  a  band  of  villilbrm  teeth:  tongue 
thick,  obtuse.     Eye  is  lateral,  not  interfering  with  the  upper  profile  of  the  head;  its  diame-

ter  (.07)  more  than  one-fourth  of  the  length  of  the  head,  and  contained  about  fourteen  times 
in  the  length  of  the  body.  Width  of  interorbital  area  is  contained  2J  times  in  length  of 
head.  Nostril  close  to  eye.  Gill  opening  a  vertical  slit,  extending  upon  upper  part  of  root 
of  the  pectoral. 

Dorsal  is  inserted  at  a  distance  from  snout  equal  to  one-third  of  length  of  body.  It 
contains  about  48  rays  (though  to  count  them  is  almost  impossible).  Anal  originates  at  a 
distance  from  snout  equal  to  two-fifths  of  length  of  body,  and  in  perpendicular  from  eighth 
dorsal  ray;  it  contains  at  least  48  rays.  Pectoral  moderately  broad,  with  15  long  rays  and 
12  or  13  shorter  ones;  the  long  rays  are  twice  as  long  as  the  ventral  disk  and  extend  nearly 
or  quite  to  perpendicular  from  vent. 

Ventral  disk  slightly  longer  (.10)  than  its  distance  from  snout  (.09),  which  precisely 
equals  its  width;  it  has  14  papillae. 

Color  is  uniform  whitish,  almost  colorless,  aud  translucent  in  life. 

This  species  was  taken  in  the  large  trawl  net  by  the  collecting  party  on  the  United 
States  steamer  Speedwell,  September  24,  1877,  off  the  mouth  of  Halifax  Harbor  (station 
117,  84  miles  southeast  from  Chebucto  Head).  The  depth  at  which  it  was  found  was  52 
fathoms,  the  temperature  at  the  bottom  35°  F.  The  bottom  was  of  fine  sand  aud  mud,  and 
in  the  same  haul  of  the  net  were  taken  the  following  species:  Glyptocephalus  cynoglossus, 
Sippoglossoides platessoides,  Sebastes  mariwus  (young),  Phycis  chuss,  Aspidophoroides  monop- 
terygius,  Triglops  Pingelii,  Gentridermichthys  uncinatus,  and  Baia  radiata. 

Specimens  of  this  species  were  also  taken  by  the  Albatross  from  station  2455,  in  47°  21' 
N.  lat.;  51°  38'  30"  W.  Ion.,  at  a  depth  of  SI  fathoms. 

The  species  resembles,  in  the  shape  of  its  head,  the  Liparis  Fabricii  of  Kroyer,  but  is 
easily  distinguished  by  its  less  elongate  body  and  the  greater  number  of  rays  in  the  dorsal 
and  anal  fins.  When  first  taken  it  was  colorless,  almost  translucent,  and  was  covered  with 
a  thick  tough  integument.  The  preceding  description  is  less  complete  than  would  seem  de- 
sirable, owing  to  the  fact  that  the  type  specimen  (No.  22310,  U.  S.  Nat.  Mus.  Cat.)  was  too 
soft  and  tender  to  admit  of  the  requisite  manipulation.  The  specimen,  Svbich  is  50  milli- 
meters in  total  lengt  h  (caudal  included),  is  a  mature  female,  having  in  the  abdominal  cavity 
many  large  eggs.

Liitken  states  that  he  received  a  great  number  of  specimens  of  this  Arctic  species  from 
the  Kara  Sea,  where  they  were  obtained  at  depths  varying  from  40  to  106  lath s. 

This  form  is  provisionally  placed  in  Careproctus,  but  we  are  quite  prepared  to  believe 
that  Gill's  Aetinochir  is  a  valid  genus.  The  fish  has  a  close  external  resemblance  to  the 
species  of  Liparis:

Careproctus  micropus,  Garman,  Discoboli,  1892,  72. 

Head  large  and  thick,  about  one-fourth  of  the  total  length,  the  caudal  included.  The 
interorbital  space  equals  in  length  the  postorbital  portion  of  the  head.  Eye  entirely  in  the 
anterior  half  of  the  head  and  one-fifth  of  its  length.  Nostrils  not  tubular.  Cleft  of  the 
mouth  not  extending  to  the  front  margin  of  the  eye.    Teeth  simple,  unicuspid. 

Vertical  fins  continuous,  caudal  very  narrow  and  pointed.  The  origin  of  the  anal  is 
opposite  to  the  eighth  dorsal  ray.  Form  of  the  pectoral  typical,  the  foremost  rays  being 
opposite  to  the  anterior  margin  of  the  ventral  disc.  Ventral  disc  circular,  small,  one-fourth 
of  the  length  of  the  head,  situated  immediately  behind  the  level  of  the  eye.  Vent  very 
close  to  ventral  disc.     Color  light  grayish  or  purplish.     (Gunther.) 

Two  specimens,  2  and  34  inches  long,  were  obtained  by  the  Knight  Errant  at  station  9, 
from  a  depth  of  608  fathoms;  and  also  a  single  individual,  3i  inches  long,  at  station  8,  in 
540  fathoms.

Paraliparis  liparinus,  GKnther,  Challenger  Report,  xxil,  1887,  62. — Garman,  Discoboli,  82. 

Body  elongate,  compressed  posteriorly,  very  thin  at  the  tail,  covered  with  a  gelatinous, 
las,  transparent  skin,  which  is  separated  from  the  body  and  the  tins  by  a  filmy,  mucous 
intertissue.     Greatest  height  of  body  (.18)  contained  5i  times  in  its  length,  without  caudal. 

Head  thick,  convex  between  eyes,  its  greatest  width  (.11)  nearly  three-fourths  its  length 
(.15),  which  is  contained  6|  times  in  the  length  of  the  body.  Snout  convex,  protruding. 
Mouth  under  the  snout  aud  far  back  from  its  tip.  Eyes  lateral,  in  diameter  (.03)  about  half, 
the  width  of  the  interorbital  area  (.05).  Nostril  in  front  of  eye.  Pores  along  the  upper  lip 
When  the  head  is  viewed  from  directly  in  front  the  opening  of  the  mouth  seems  to  be  convex 
upward. 

The  dorsal  fin  begins  over  the  end  of  the  pectoral,  and  the  rays  and  outline  of  this,  as 
well  as  of  the  anal,  are  hardly  visible  through  the  thick,  lax  skin.  The  rays  are  thick,  but 
very  flexible.  The  anal  begins  under  the  eighth  to  tenth  dorsal  ray.  The  dorsal  and  anal 
rays  lie  closely  connected  with  those  of  the  caudal,  "which  are  somewhat  longer,  and  extend 
in  a  pencil-like  point. 

The  pectoral  is  broad,  its  lower  base  almost  under  the  posterior  margin  of  the  orbit. 
It  is  composed  of  twenty-three  rays,  the  six  lowest  of  which  are  prolonged  beyond  the  lower 
rays,  contiguous. 

Radial  formula:  D.  G7;  A.  51 ;  C.  6;  P.  23. 

Color,  yellowish  white,  dusky  toward  the  tail  and  blackish  upon  the  anterior  part  of

Knight  Errant  collected  it  at  station  8,  1882,  iu  040  fathoms. 

PARALIPARIS  COl'EI,  GOOSE  and  Bean,  n.  s.     (Figure  253.) 

This  species  has  nearly  the  same  number  of  rays  in  the  dorsal  and  anal  as  are  recorded 
in  P.  bathybius,  but  the  pectoral  has  17  rays  in  the  upper  portion  and  3  in  the  lower.  The 
jaws  are  shorter  than  in  P.  bathybius;  the  form  is  more  elongate  and  the  coloration  is  strik- 
ingly different,  our  species  having  the  anterior  half  of  the  body  pale,  almost  whitish,  while 
the  snout,  chin,  and  anal  origin  are  black. 

The  standard  length,  which  is  the  total  without  caudal,  of  the  specimen  examined  is 
107  millimeters.  The  greatest  height  of  the  body  (25  millimeters)  is  slightly  greater  than 
the  length  of  the  head,  which  is  contained  0*  times  in  the  standard  length. 

The  snout  is  broad,  obtuse,  its  length  (7  millimeters)  contained  3.i  times  in  that  of  the 
head.  The  length  of  the  eye  equals  that  of  the  snont.  The  interorbital  width  (11  milli- 
meters) equals  the  length  of  the  postorbital  part  of  the  head.  The  nostril  is  about  midwaj 
between  the  eye  and  the  tip  of  the  snout,  in  a  very  short  tube.  Five  large  mucous  pores 
on  each  side  of  the  snout.  3  smaller  ones  on  the  cheek  under  the  eye  and  0  on  the  man- 
dible and  edge  of  the  opercular  bones.  The  teeth  are  minute,  villi  form,  and  in  two  series. 
The  gill-opening  is  a  very  small  slit,  edged  with  black  at  the  upper  angle  of  the  pectoral. 
The  origin  of  the  dorsal  is  distant  from  the  snout  30  millimeters,  or  l.J.  times  the  length  of 


280  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

the  head.  The  tip  of  the  pectoral  when  extended  is  about  under  the  second  or  third  ray  of 
the  dorsal.  The  anal  origin  is  under  the  ninth  or  tenth  dorsal  ray.  The  length  of  the 
middle  caudal  ray  (16  millimeters)  is  contained  10i  times  in  the  standard  length.  The 
longest  pectoral  ray  (18  millimeters)  ecpuals  half  the  distance  from  the  snout  to  the  dorsal. 
The  longest  ray  of  the  isolated  portion  of  the  fin  (10  millimeters)  equals  that  of  the  middle 
caudal  ray.  The  distance  of  the  vent  from  the  tip  of  the  snout  (23  millimeters)  is  nearly 
equal  to  the  length  of  the  head.  The  vent  is  directly  under  the  base  of  the  pectoral;  it  is 
a  narrow  slit  placed  horizontally.     Pyloric  caeca  4  to  (!. 

Color:  Auterior  half  of  body  very  pale,  whitish;  posterior  half  very  light  brown; 
snout,  chin,  and  edge  of  gill-opening  and  region  about  the  vent  black. 

Eadial  formula:  D.  60;  A.  55;  P.  17  +  4;  C.  10. 

The  eggs  of  an  example  a  little  smaller  than  the  type  of  the  description  have  a  diam- 
eter of  about  3  millimeters.  At  the  same  time  the  ovaries  contain  some  eggs,  which  have 
not  reached  maturity,  whose  diameter  is  only  about  one-half  millimeter.  The  stomach  is  a 
stout  subspherical  receptacle,  its  greatest  width  two  thirds  of  its  length. 

The  type  specimen  (Cat.  No.  35637,  U.  S.  N.  M.)  was  taken  by  the  Albatross  on  Sept. 
13,  1884,  from  station  2232,  in  39°  12'  17"  N.  lat.,  72°  09'*30"  W.  Ion.,  at  a  depth  of  520 
fathoms.  Specimens  were  also  taken  by  the  same  vessel  from  station  2546,  in  39°  53'  30" 
N.  lat.,  70°  17'  30"  W.  Ion.,  at  a  depth  of  538  fathoms;  from  station  2187,  in  39°  49'  30"  N.

HILGENDORFIA,  Goode  and  Bean,  n.  g. 

Liparids  with  large,  high,  compressed  head  whoso  bones  are  exceedingly  thin,  cavernous; 
jaws  even  in  front,  Vertical  tins  represented  by  broad  median  folds,  confluent  at  the  pos- 
terior end  of  the  body,  where  the  caudal  is  represented  by  two  or  three  extremely  fine, 
slender  terminal  filaments.  Pectoral  very  large,  broad-based,  with  membranes  fringed  pos 
teriorly  and  having  several  of  the  lower  rays  free,  though  not  forming  a  distinct  portion  of 
the  fin.  No  ventral  disk.  Vent  far  advanced,  opposite  hind  margin  of  orbit.  Gill  opening 
as  in  Monomitra. 

The  type  described  by  Giinther  is  only  60  millimeters  in  length,  and  he  remarks 
concerning  it  that  it  is  uncertain  whether  it  represents  a  form  in  which  embryonic  charac- 
ters are  persistent,  or  merely  an  early  stage  of  development. 

Its  peculiarities  seem  sufficient  to  warrant  its  being  set  apart  for  further  study  before  it 
is  merged  with  Paraliparis.  It  is  named  for  Dr.  Franz  Uilgendorf,  of  the  Royal  Zoological 
Museum,  Berlin

Paraliparis  memhranaceus,  Gcntiier,  Challenger  Report,  xxn,  1887,  p.  69,  pi.  XII,  fig.  D. 

Head  very  large,  compressed,  about  as  high  as  long,  with  the  upper  profile  descending 
in  a  parabolic  curve.  The  abdominal  cavity,  black  and  transparent  through  the  integu- 
ments, is  excessively  short;  the  tail  compressed  and  gradually  tapering  into  a  fine  point, 
The  whole  of  the  integuments  are  colorless,  with  minute  scattered  points  of  pigment,  A 
broad  median  dorsal  fold  rises  from  the  top  of  the  snout  and  is  continued  to  the  extremity 
of  the  tail,  gradually  disappearing  as  it  approaches  the  caudal  fin,  which  is  represented  by 
two  or  three  extremely  tine  and  rather  long  terminal  filaments.  The  fold  is  highest  above 
the  posterior  portion  of  the  abdomen;  there  also  fin  rays  commence  to  be  developed,  which 
on  the  anterior  half  of  the  tail  are  distinct  enough,  but  become  more  crowded  posteriorly 
and  almost  indistinguishable.  The  anal  has  a  similar  structure;  it  also  starts  as  a  fold 
from  the  vent,  which  is  far  advanced,  opposite  to  the  hind  margin  of  the  orbit;  rays  are 
developed  from  the  posterior  end  of  the  abdominal  cavity,  whence  the  fin  is  continued  in 
the  same  manner  as  the  dorsal. 

Pectoral  fin  very  large,  with  a  very  broad  base,  extending  from  the  upper  end  of  the 
gill  opening  forward  nearly  to  the  hyoid  bone;  its  principal  portion  consists  of  an  extremely

delicate  membrane,  in  which  rays  are  visible  like  fine  striae,  and  which  on  its  hinder  margin 
is  provided  with  long  Cringes.  The  eight  lower  or  anterior  rays  are  quite  free,  bu1  not  sep 
arated  by  an  interspace  from  the  remaining  pari  of  the  fin.  The  bonesofthe  head  are 
extremely  thin,  forming  cavities  on  the  top  and  the  snout.  Tlie  eye  is  of  moderate  size, 
about  two-sevenths  of  the  length  of  the  head,  a  little  shorter  than  the  snout,  and  consider- 
ably less  than  the  width  of  the  interoi  lutal  space,  which  is  very  convex.  .laws  even  in

Pisces,  18. 

Body  compressed,  tapering,  ensiform;  skin  feebly  adherent  to  the  subjacent  tissues, 
and  scaleless.  Vertical  tins  confluent,  pectorals  enveloped  in  an  integument;  ventrals 
jugular,  .laws  with  line  teeth  in  several  rows,  disposed  in  quincunx  fashion;  vomer  and 
palatines  toothless.     Branchial  opening  small  and  placed  a  little  above  the  pectorals. 

This  genus,  which  Vaillant  places  in  the  family  Lycodicke,  while  calling  attention  to  its 
resemblance  to  the  Brotulids,  has  been  assigned  by  Boulenger  to  the  Discoboli,  where  we 
provisionally  leave  it.

form  is  globose  (so  far  as  Vaillant  was  able  to  judge  from  a  distorted  specimen).  Length 
of  snout  two-fifths  that  of  head.  Mouth  large,  the  maxillary  extending  to  the  vertical 
from  the  center  of  the  eye.  On  the  intermaxillary  and  mandible  are  small,  smooth,  pave- 
ment-like teeth,  similar  to  those  which  occur  in  certain  Elasmobranchs,  like  Mtistelus,  and 
certain  Kays;  palate  smooth.  Eye  moderate,  diameter  one-fifth  of  length  of  head;  interor 
bital  width  greater,  the  space  equal  to  one-third  that  of  the  head.  No  barbel  lias  been  ob- 
served. The  branchial  orifice  consists  of  a  simple  openiug.  Opercular  bones  apparently 
imperfectly  developed.  Branchiostegal  membrane  supported  by  rays  which  are  relatively 
long  and  strong,  which,  in  the  individual  as  it  was  captured,  are  bent,  distending  the  mem- 
brane in  globular  form.     Vent  a  little  in  advance  of  the  anterior  third  of  the  body. 

It  is  impossible,  says  Vaillant,  to  know  whether  there  was,  or  was  not,  a  lateral  line,  the 
skin,  which  is  very  loose,  as  in  certain  species  such  as  Liparis,  being  absent  from  most 
parts  of  the  body.  Skin  absolutely  devoid  of  scales,  but  studded  with  numerous  pigmen- 
tary dots  which  cover  it  nearly  entirely — head,  body,  and  fins. 

The  dorsal  does  not  appear  to  commence  very  far  forward,  its  origin  being  nearly  in 
the  vertical  from  the  vent;  that  of  the  anal  considerably  farther  back.  The  two  vertical 
fins  are  similar  in  appearance  and  size;  they  are  confluent  at  the  posterior  extremity  of  the 
body,  where,  properly  speaking,  there  is  no  caudal.  Pectorals  are  completely  enveloped  in 
the  skin,  and  have  from  11  to  1">  rays. 

When  taken  out  of  the  dredge  the  fish  was  entirely  brown;  dark  upon  the  tins;  belly 
bluish-black;  the  inside  of  the  mouth  and  branchial  cavity  brownish,  witli  some  scattering 
pigmentary  spots. 

A  single  specimen  was  obtained  by  the  French  vessels  at  station  xxi.  oil  the  coast  of 
Morocco,  at  a  depth  of  1,319  meters.

284  DEEP-SEA   FISHES    OF   THE    ATLANTIC    BASIN. 

Tip  to  the  time  of  the  visit  of  the  U.  S.  Fish  Commission  to  Salem  in  1877  this  species 
had  been  very  rarely  taken  south  of  Greenland,  and  that  mainly  from  the  stomachs  of  cod, 
haddock,  halibut,  and  other  fishes.  Several  specimens  were  dredged  by  the  Commission  at 
Portland  and  Eastport,  Me.  Many  specimens  were  taken  in  Massachusetts  Bay,  often  a 
dozen  coming  up  in  a  single  haul  of  the  trawl. 

In  1871  the  head  of  au  individual  of  this  species  was  dredged  up  on  the  ''Pecten  Ground,'' 
off  Watch  Hill,  R.  I.    This  was  the  first  instance  of  its  capture  south  of  Cape  Cod. 

It  was  subsequently  taken  at  the  following  Albatross  stations:  2502,  in  44°  19'  N".  lat., 
G0°  39'  15"  W.  Ion.,  at  a  depth  of  54  fathoms;  2491,  in  45°  24'  30"  K  lat.,  58°  35'  15"  YV. 
Ion.,  at  a  depth  of  59  fathoms;  2522,  in  42°  20'  1ST.  hit.,  65°  07'  30"  W.lon.,  at  a  depth  of  101 
fathoms;  and  2450,  in  46°  45'  N.  lat.,  50°  02'  30"  W.  Ion.,  at  a  depth  of  44  fathoms. 

A  specimen,  doubtfully  assigned  to  A.  Olriki,  was  taken  at  station  2450,  in  40°  45'  N. 
lat.,  50°  02'  30"  W.  Ion.,  at  a  depth  of  44  fathoms.

A  Lopholatilus  having  a  stout,  somewhat  compressed  body,  with  its  height  contained 
3J  times  in  its  length  (without  caudal),  and  the  length  of  its  head  3  times. 

Maxillary  reaching  anterior  margin  of  orbit;  opercle  and  preopercle  scaly,  the  latter 
finely  denticulate;  upper  jaw  with  an  outer  series  of  stronger  teeth,  behind  which  is  a  band

Radial  formula:  D.  vn,  15;  A.  n,  13;  scales  8-93-30. 

Detailed  description. — The  greatest  height  of  the  body  (.306),  which  is  at  the  ventrals, 
is  contained  about  3;V  times  in  the  length  to  the  origin  of  the  middle  caudal  rays,  and  4  times 
in  the  extreme  length.  Its  greatest  width  (.144)  equals  the  length  of  the  caudal  peduncle 
(.144) ;  this  latter  being  measured  from  the  end  of  the  soft  dorsal  to  the  origin  of  the  middle 
caudal  rays.  The  least  height  of  the  tail  (.0807)  is  contained  4  times  in  the  distance  of  the 
spinous  dorsal  from  the  snout. 

The  greatest  length  of  the  head  (.33)  is  contained  3  times  in  the  length  to  the  origin  of 
the  middle  caudal  rays.  Its  greatest  width  (.165)  is  slightly  more  than  twice  the  width  of 
the  iuterorbital  area  (.08).    The  length  of  the  snout  (.122)  is  contained  twice  in  the  length 


DISCUSSION    OF    SPECIES   AND   THEIR    DISTRIBUTION.  285 

of  the  pectoral  of  the  right  side  (.244).  The  length  of  the  operculum  to  end  of  flap  (.11)  is 
.',  of  total  Length.  The  length  of  the  upper  jaw  (.15)  equals  A  the  height  of  the  body  al  the 
ventrals,  and  is  contained  -'  times  in  the  length  of  the  head.  The  maxilla  extends  to  the 
perpendicular  through  the  anterior  margin  of  I  lie  orbit ;  the  mandible  does  not  <piite  reach 
the  perpendicular  through  the  middle  of  the  orbit;  the  length  of  the  labial  appendage  is 
slightly  more  than  half  the  long  diameter  of  the  orbit  and  one-third  the  length  of  the  first 
peel  oral  ray.  The  length  of  the  mandible  (.lot!)  slightly  exceeds  the  distance  from  the  sin  nit 
to  the  orbit  (.15),  and  equals  .'!  times  the  long  diameter  of  the  eye  (.052),  which  is  contained 
0A  times  in  the  length  of  the  head.  The  operculum  and  preoperculum  are  scaly;  the  latter 
is  finely  denticulated  on  its  posterior  margin.  The  distance  of  the  posterior  nostril  from 
the  eye  equals  the  length  of  the  lirst  anal  spine;  the  distance  between  the  anterior  nostril 
and  the  end  of  the  snout  is  twice  as  great.  The  intermaxillaries  are  supplied  with  an  outer 
series  of  about  19  canine  teeth,  and  behind  these  a  band  of  villiform  teeth,  widest  at  the  sym- 
physis. The  mandible  has  a  few  large  canines  and  an  inner  series  of  small  conical  teeth 
continued  from  a  patch  of  similar  teeth  at  the  symphysis;  vomer  and  palatines  toothless. 

The  distance  of  the  adipose  dorsal  from  the  snout  (.206)  equals  nearly  3  times  its  height 
(.07);  its  length  of  base  (.123)  equals  the  length  of  the  snout.  The  height  of  the  adipose 
dorsal  equals  the  distance  from  the  tip  of  the  ventral  to  the  vent. 

The  distance  of  the  spinous  dorsal  from  the  snout  (.347)  equals  the  distance  of  the  ven- 
fcral  from  the  snout  (.317);  its  length  of  base  (.114)  equals  the  length  of  the  caudal  peduncle. 
The  first  spine  is  imperfect — what  remains  of  it  is  one-third  as  long  as  the  third  spine  (.09). 
The  second  spine  (.08L')  is  about  equal  to  the  width  of  the  interorbital  ana.  The  fourth  and 
the  sixth  spine  are  equal  in  length  (.097)  and  equal  the  distance  from  the  end  of  the  snout 
to  the  posterior  nostril.  The  fifth  spine  (.095)  is  a  little  shorter  than  the  sixth.  The  last 
spine,  seventh,  is  contained  10  times  in  the  total  length.  The  length  of  the  first  ray  of  the 
soft  dorsal  (.094)  equals  the  distance  between  the  anterior  nostril  and  the  end  of  the  snout. 
The  thirteenth  and  longest  ray  (.147)  about  equals  the  length  of  the  base  of  the  spinous 
dorsal.  The  last  ray  (.07)  is  half  as  long  as  the  thirteenth.  The  thirteenth  ray  of  the  soft 
dorsal  extends  to  the  origin  of  the  external  caudal  rays. 

The  distance  of  the  anal  from  the  snout  (.00)  is  about  equal  to  twice  the  height  of  the 
body  at  the  ventrals.  The  length  of  the  anal  base  (.318)  is  slightly  more  than  twice  the 
length  of  the  mandible.  The  first  anal  spine  (.04)  is  half  as  long  as  the  second  dorsal  spine. 
The  second  anal  spine  (.075)  is  half  as  long  as  the  upper  jaw.  The  first  ray  of  the  anal  (.102) 
is  as  long  as  the  last  spine  of  the  dorsal.  The  eleventh  and  longest  anal  ray  (.134)  is  con- 
tained 7.1  times  in  the  total  length,  and  nearly  equals  the  length  of  the  middle  caudal  rays. 
The  last  anal  ray  (.078)  is  half  as  long  as  the  mandible.  The  eleventh  ray  of  the  anal 
extends  almost  to  the  perpendicular  through  the  origin  of  the  middle  caudal  rays. 

The  caudal  is  emarginate,  the  external  rays  being  only  1A  times  as  long  as  the  middle 
rays.  The  length  of  the  superior  external  rays  (.210),  measured  from  the  origin  of  the  mid- 
dle rays,  equals  1A  times  the  length  of  the  spinous  dorsal  base. 

The  distance  of  the  pectoral  from  the  snout  (.32)  very  slightly  exceeds  the  length  of 
the  anal  base.  The  length  of  the  pectoral  of  the  right  side  (.244)  equals  twice  that  of  the 
snout.  The  pectoral  of  the  left  side  is  probably  imperfect,  its  length  (.216)  being  equal  to 
that  of  the  superior  external  caudal  rays.  The  right  pectoral  can  be  made  to  reach  the  vent ; 
in  its  natural  positiou  it  extends  to  the  perpendicular  let  fall  from  the  fourth  ray  of  the 
second  dorsal. 

The  distance  of  the  ventral  from  the  snout  (.347)  equals  4  times  the  least  height  of 
the  tail.  The  length  of  the  ventral  (.183)  equals  twice  that  of  the  third  dorsal  spine,  and 
it  extends  to  a  point  under  the  third  dorsal  ray.  The  distance  from  the  tip  of  the  ventral 
to  the  vent  equals  half  the  length  of  the  middle  caudal  rays.  The  vent  is  under  the  inter- 
val between  the  fourth  and  fifth  dorsal  rays. 

Color. — The  following  notes  upon  color  were  taken  from  a  fresh  specimen.  The  colors 
are  very  beautiful,  and  in  general  appearance  when  taken  from  the  water  it  is  one  of  the 
Loveliest  fishes  we  have  ever  seen,  no  exception  being  made  in  favor  of  the  brilliant  parrot- 
fishes  or  angel-fishes  of  the  West  Indian  coral  groves.

Alimentary  canal  short,  stomach  and  intestine  when  stretched  out  at  full  length  extending 
from  the  diaphragm  to  the  caudal.  A  loop  in  the  intestine  immediately  posterior  to  the 
stomach.  Liver  with  two  lobes,  nearly  equal  in  length,  light  chestnut-brown.  Gall-bladder 
large,  pendent,  pear-shaped,  with  long  duct.  Swim-bladder  simple,  with  thick  muscular 
walls,  strongly  attached  to  roof  of  abdominal  cavity  by  numerous  root-like  appendages,, 
resembling  somewhat  those  of  Pogonias.    Spleen  two-thirds  as  long  as  gall-bladder.

This  fish  was  first  observed  in  1879,  when  a  Cape  Aim  schooner,  the  Wm.  V.  Hutchitujs, 
while  setting  trawl  lines  for  cod  on  Nantucket  shoals,  took  several  hundred  specimens. 
The  capture  of  so  large  a  fish  so  entirely  unlike  anything  known  in  American  waters  excited 
much  interest,  and  it  was  at  first  thought  that  it  might  become  of  economic  importance. 
The  genus  and  species  were  immediately  described,  and  a  popular  name  was  proposed, 
taken  from  the  fourth  syllable  of  the  name  of  the  genus. 

In  July  of  the  same  year,  the  schooner  Clara  F.  Friend,  while  fishing  for  cod  iu  the  same 
region,  obtained  nine  of  them  at  a  station  50  miles  south  by  east  of  Noman's  Laud,  in  N. 
hit.  40°  10',  W.  Ion.  70°  55',  at  a  depth  of  75  fathoms,  on  very  hard  clay  bottom.  In  Sep- 
tember the  Fish  Commission  steamer  Fish  Haiok  went  to  the  same  region  to  search  for 

them. 

The  first  trip  of  the  Fish  Hawk  to  deep  water  from  Newport  was  on  September  4,  and 
the  nets  were  hauled  as  nearly  as  possible  on  the  same  grounds  where  Lopholatilus  had 
previously  been  taken.  The  second  trip,  ten  days  later,  was  to  a  region  about  40  miles 
farther  west,  and  on  this  occasion  six  or  more  large  individuals  of  this  species  were  brought 
up  on  a  hand  line  ( ladder  line)  set  from  an  open  boat  sent  out  from  the  steamer.  None 
were  at  any  time  taken  in  the  trawl  nets,  though  there  is  every  reason  to  believe  from  the 
success  of  the  fishing  vessels  previously,  and  from  the  number  taken  on  the  hand  line  by 
the  men  in  the  small  boat,  that  they  were  exceedingly  abundant  in  this  locality,  and  proba- 
bly for  hundreds  of  miles  in  either  direction,  or  at  any  rate  to  the  south. 

In  18S0  and  18S1  the  Fish  Hawk  took  tile  fish  on  several  occasions  at  depths  of  from 
70  to  134  fathoms.  The  indications  of  the  apparent  abundance  of  a  new  and  edible  fish  of 
large  size  made  Prof.  Baird  desirous  of  obtaining  fuller  knowledge  of  its  habits  and  habi- 
tat, iu  the  hope  that  it  might  readily  be  taken  in  large  numbers  and  prove  an  important 
addition  to  the  list  of  food-fishes.  Unfortunately  the  Fish  Commission  had  not  yet  built 
the  schooner  Grampus,  so,  having  no  vessel  especially  adapted  for  fishery  research  and  pre- 
pared to  encounter  all  weather,  it  was  necessary  to  charter  a  fishing  smack  for  the  work. 
Unfortunately,  too,  bad  or  threatening  weather  seemed  to  have  been  chartered  with  the 
smack,  and  only  a  brief  and  unsatisfactory  trial  could  be  made  on  the  tile  fish  ground,  so 
that  research  was  of  necessity  postponed  until  1882.  In  the  months  of  March  and  April, 
lssi".  vessels  arriving  at  Philadelphia,  New  York,  and  Boston  reported  having  passed  large 
numbers  of  dead  or  dying  tish  scattered  over  an  area  of  many  miles,  and  from  descriptions 
and  the  occasional  specimens  brought  in,  it  was  evident  that  the  great  majority  of  these 
were  tile  fish.  Naturally  these  fish  were  not  evenly  distributed  over  all  the  area  in 
which  they  were  seen,  some  observers  reporting  them  as  scattering,  and  others  as  at  times 
so  numerous  that  there  would  be  as  many  as  fifty  on  the  space  of  a  rod  square.    As  one

account  after  another  came  in  it  became  apparent  that  a  vast  destruction  of  fish  had  taken 
place,  for  vessels  reported  having  sailed  for  40,  50,  and  60  miles  through  floating  fish;  and 
in  one  case  the  schooner  TJTavarino  sailed  for  above  150  miles  through  waters  dotted  as  far 
as  the  eye  could  reach  with  dying  fishes.  Computations  made  by  Capt.  J.  W.  Collins, 
seemed  to  indicate  that  an  area  of  from  5,000  to  7,500  square  statute  miles  was  so  thickly 
covered  with  dead  or  dying  fish  that  their  numbers  must  have  exceeded  the  enor 
inous  number  of  one  billion.  Since  there  were  no  signs  of  any  disease,  and  no  parasites 
found  on  the  fish  brought  in  for  examination,  their  death  could  not  have  been  brought 
about  by  either  of  these  causes;  and  many  conjectures  were  made  as  to  the  reason  of  this 
wholesale  destruction  of  deep-water  fishes,  such  as  would  ordinarily  be  unaffected  by 
conditions  prevailing  at  the  surface,  submarine  volcanoes,  heat,  cold,  and  poisonous 
gases  being  variously  brought  forward  to  account  for  the  loss  of  life. 

Prof.  Verrill  has  noted  the  occurrence  of  a  strip  of  water,  having  a  temperature  of  48° 
to  50°  F.,  lying  on  the  border  of  the  Gulf- Stream  slope,  sandwiched  between  the  Arctic 
current  on  the  one  hand  and  the  cold  depths  of  the  sea  on  the  other.  During  1880  and 
18S1  Prof.  Verrill  dredged  along  the  Gulf-Stream  slope,  obtaining  in  this  warm  belt,  as  he 
terms  it,  many  species  of  invertebrates  characteristic  of  more  southern  localities.  In  1882  the 
samespecies  were  scarce  or  totally  absent  from  places  where  they  had  previously  beenabuud- 
ant,  and  this  taken  in  connection  with  the  occurrence  of  heavy  northerly  gales  and  the  pres- 
ence of  much  iushore  ice  at  the  north,  leaves  little  doubt  that  some  unusual  lowering  of  tem- 
perature in  the  warm  belt  brought  immediate  death  to  many  of  its  inhabitants.  This  is  the 
more  probable,  as  it  is  a  well-known  fact  that  sudden  increase  of  cold  will  bring  many  fish  to 
the  surface  in  a  benumbed  or  dying  condition,  and  there  are  no  indications  of  any  shock  or 
earthquake  having  occurred  at  the  time  the  dead  fish  were  first  noticed.1 

For  several  years  the  fish  was  believed  to  have  become  entirely  extinct,  and  so  con- 
vinced were  naturalists  of  this  that  a  chapter  was  devoted  to  it  in  a  paper  by  Mr.  Lucas  in 
the  Report  of  the  National  Museum  for  1889  upon  "Animals  recently  extinct."  Several 
visits  were  made  by  Fish  Commission  vessels  to  the  old  Lopholatilus  grounds,  but  all 
attempts  to  obtain  specimens  were  fruitless. 

In  the  fall  of  1892  Col.  Marshall  McDonald,  the  Commissioner  of  Fisheries,  made 
another  attempt  to  discover  the  fish,  and  was  successful,  obtaining  it  from  the  following 
stations:  A  single  specimen  on  August  6,  in  40°  06'  X.  hit.,  71°  00'  W.  Ion.,  in  78  fathoms; 
one  specimen  on  August  18,  in  40°  08'  X.  hit.,  71° 08'  W.  Ion.,  in  78  fathoms;  one  specimen 
on  September  17,  in  39°  26'  X.  lat.,  72°  22'  W.  Ion.,  at  a  depth  of  74  fathoms;  three  speci- 
mens on  September  IS,  in  39°  20'  X.  hit.,  72°  27'  W.  long.,  in  77  fathoms,  and  two  speci- 
mens on  October  8,  in  38°  40'  X.  lat.,  73°  09'  W.  Ion.,  at  a  depth  of  80  fathoms. 

The  tile  fish  then  is  restored  to  the  list  of  existing  species  of  our  Xorth  Atlantic  coast, 
and  it  is  probable  that  in  time  it  may  attain  to  its  former  abundance.  The  temperature 
investigations  made  by  Col.  McDonald  have  been  carefully  discussed  by  him,  and  he  is 
convinced  that  the  destruction  of  Lopholatilus  was  due  entirely  to  climatic  causes.

808. 

Body  elongate,  subcylindrical,  tapering-  posteriorly.  Head  very  large,  much  depressed, 
with  snout  elongate,  spatulate;  cleft  of  mouth  very  wide,  horizontal,  with  the  lower  jaw 
much  the  longer;  the  posterior  margin  of  the  maxillary  wide,  free,  and  with  a  long  cuta- 
neous flap.  Eyes  very  large,  close  together,  subvertical.  Scales  large,  cycloid,  deciduous; 
lateral  line  conspicuous  and  continuous,  with  scales  smaller  than  those  of  the  body  adjoining, 
not  granular,  its  line  descending  abruptly  in  a  catenary  curve  in  the  region  over  the  pectorals. 
Teeth  acicular;  in  bands  on  the  jaws,  vomer,  and  palatines,  the  largest  being  upon  the  pala- 
tines, the  vomer,  and  upon  two  pads  on  either  side  of  the  symphysis  of  the  maxillary.  A 
sharp,  short,  strong  scapular  spine.  Opercle  with  three  feeble,  sharp  spines,  each  at  the 
end  of  a  long  feeble  ridge;  a  long,  skinny  opercular  flap  extending  far  beyond  the  bony 
portion,  and  covered  with  scales.  Brauchiostegals,  0.  Gill-membranes  free  from  the  isth- 
mus, except  far  in  front,  where  they  are  united  fco  it;  the  left-hand  flap  overlapping  the 
right  at  the  point  of  junction.     Psendobranchia?  present.     Gill-rakers  short. 

This  genus  resembles  Ghcenichthys,  in  many  particulars,  in  its  general  structure,  though 
distinguished  by  the  presence  of  scales  and  the  different  position  of  the  lateral  line,  which 
descends  in  a  ca  tenary  curve  from  under  the  tip  of  the  opercular  flap  to  the  middle  region 
of  the  body,  about  halfway  from  the  pectorals  to  the  caudal;  by  the  greater  depression  of 
the  head,  the  sharper  snout,  the  smaller  mouth,  and  the  location  of  the  eyes,  which  are 
subvertical  instead  of  lateral,  and  are  separated  by  a  very  narrow interorbital  space;  and  also 
by  the  presence  of  teeth  upon  the  vomer  and  palatines.  It  resembles  Bathydraco  in  general 
appearance,  but  is  clearly  distinguished  from  it  by  the  presence  of  two  dorsal  lins,  instead 
of  a  single  one,  by  the  armed  opercles,  by  the  presence  of  scales  upon  the  snout,  by  the 
presenceof  teeth  upon  the  vomer  and  palatines,  and  by  having  0  instead  of  10  brauchios- 
tegals.

The  greatest  height  of  the  body  is  about  one  third  of  the  length  of  the  head,  which 
(measuring  from  the  tip  of  the  snout  to  the  tip  of  the  opercular  Bap)  is  contained  a  little  less 
than  two  and  one-half  times  in  the  total  length  of  the  body  (without  caudal).  Mouth  very 
wide,  horizontal;  the  maxillary,  which  is  expanded  spoon-like  posteriorly,  reaching  consid- 
erably beyond  the  vertical  from  the  anterior  margin  of  the  orbit.  The  diameter  of  the  orbit 
is  contained  1A  times  in  the  length  of  the  snout  and  i.\  times  in  the  length  of  the  head  (flap 
included),  its  location  being  considerably  nearer  to  the  tip  of  the  snout  than  to  the  end  of 
the  flap,  and  equidistant  between  the  tip  of  the  snout  and  the  tip  of  the  uppermost  spiue  of 
the  operculum. 

The  entire  upper  surface  of  the  head  is  covered  with  scales,  except  upon  the  bony  por- 
tion of  the  snout,  aud  so  are  also  the  cheeks  and  opercula.  The  first  d<  >rsal  tin  is  placed  far 
forward,  not  far  behind  the  vertical  from  the  axil  of  the  pectoral;  the  interspace  between 
the  termination  of  the  first  dorsal  and  the  beginning  of  the  second  is  equal  to  the  diameter 
of  the  orbit.  This  flu  is  composed  of  six  spines,  the  first  aud  second  of  which  are  the  long- 
est, equal  to  the  distance  from  the  anterior  margin  of  the  orbit  to  the  tip  of  the  lower  jaw, 
and  is  triangular  in  form.  The  origin  of  the  second  dorsal  is  almost  in  the  vertical  from 
that  of  the  anal,  and  terminates  a  little  in  advance  of  the  latter.  The  second  dorsal  tin  is 
highest  in  front  aud  low  behind.  The  length  of  the  caudal  peduncle  is  a  little  less  than  the 
length  of  the  snout.  Caudal  rounded.  Pectoral  very  broad  at  base,  rounded,  extending 
beyond  the  vent  aud  nearly  to  the  vertical  from  the  origin  of  the  anal ;  lower  rays  branched. 
Veutralsfar  apart,  horizontal,  Trigla-Uke,  composed  of  one  flexible  spine  aud  five  branched 
rays,  their  insertion  far  forward  and  far  in  advance  of  the  base  of  the  pectorals.

Color,  entirely  black.     (Giinther.) 

The  first  specimen  of  this  remarkable  fish  was  obtained  at  Magdalena  (Madeira),  at  a 
depth  of  312  fathoms,  in  1850,  by  Lowe,  who,  however,  omitted  to  give  a  description  of  it. 
The  species  was  rediscovered  at  the  same  locality  by  Johnson  twelve  years  later.  A  third 
specimen  was  picked  up  from  the  surface,  near  the  island  of  Dominica.  A  fourth  example 
was  obtained  by  the  Challenger  in  mid-Atlantic,  at  station  107,  in  15<l()  fathoms,  on  August 
26, 1873.  A  fifth  was  obtained  by  the  I'.  S.  National  Museum  from  ('apt.  Thomas  F.  llodg- 
don  of  the  Gloucester  schooner  Bessie  W.  Somers.  It  was  found  on  Le  Have  Bank,  floating 
on  the  surface,  in  June,  1880. 

It  is  evidently  an  inhabitant  of  very  great  depths.

Body  fusiform,  scaleless.  Mouth  and  gill-openings  very  large.  Eyes  moderate  and 
mouth  with  slender  teeth  turned  inward  and  placed  close  together.  Ventral  fins  subtho-

ous lines  of  pores  along  the  upper  jaw  and  mandible;  also  a  second  line  of  pores  in  front 
of  the  ventral  fins;  another  line  of  pores  unites  the  base  of  the  ventrals  and  runs  down 
the  inner  ventral  ray  on  either  side.  The  median  line  of  pores  divides  into  two  in  front 
of  the  vent  and  passes  on  either  side  of  the  anal  tin,  terminating  at  its  posterior  extremity. 
A  short  median  line  on  the  underside  of  body  in  front  of  the  root  of  caudal.  The  lateral

This  is  a  little  fish  with  the  ordinary  fish  shape,  whose  greatest  height  (15  millimeters) 
is  contained  5|  times  in  the  total  length  (82  millimeters,  caudal  included),  the  length  of  the 
head,  the  form  of  which  shows  no  peculiarity,  scarcely  4  times.  The  fine  skin  was  evi- 
dently altogether  scaleless.  The  gill  cavities  are  comparatively  large;  the  gill  membrane, 
however,  is  not  free  from  the  isthmus  in  front.    The  upper  jaw,  which  is  formed  by  the  in-

termaxdlary  alone,  bears  along  its  margin  a  series  of  small  teeth,  and  inside  of  these  is  a 
series  which  is  directed  inward  toward  the  month,  whose  palate  on  botli  sides  is  furnished 
with  numerous  thin  and  feeble  teeth,  directed  inward  toward  the  mouth  and  arranged  in 
a  cardiform  band;  the  vomer,  on  tlie  contrary,  is  toothless.  The  teeth  of  the  mandible  are 
variable  in  size,  some  long,  some  short.  The  eye  is  of  medium  size,  its  diameter  less  than 
its  distance  from  the  point  of  the  snout.  .Many  ofthe  scales  of  the  bead — forehead  and  nuchal 
regions — and  the  upper  ridge  of  the  shoulder  girdle  show  well  developed  sculpturings.  The 
mucous  pores  of  the  head  ipits  and  branches  of  the  lateral  line)  are  especially  developed 
on  the  forehead  and  temporal  regions,  behind  the  eyes,  along  the  preoperculum,  etc.  On 
many  parts  of  the  skin  are  seen  sharply  denned  lines;  series  of  closely  placed  pores — for 
example,  a  series  begins  on  the  isthmus,  close  behind  the  angle  formed  by  t he  gill-opening, 
and  runs  along  the  median  line  of  the  hods  until  about  the  ventral  tins,  then  begins  again 
a  little  behind  these  and  continues  to  the  sent,  where  it  is  divided  into  two  branches,  the 
first  curved  up  on  the  side  and  so  backward,  running  along  parallel  to.  bul  at  some  distance 
from  the  anal  tin  on  each  side  for  its  w  hole  length  :  finally  there  is  a  little  posterior  broader 
portion  in  the  middle  line  iu  front  of  the  caudal  tin.  Immediately  behind  the  ventral  tins 
there  is  a  short  cross  line  of  the  same  structure,  and  it  is  continued  on  each  side  at  a  right 
angle  along  the  innermost  ventral  ray.  The  lateral  line  consists  of  only  a  single  series  of 
rather  large  pores,  but  the  pore  system  of  the  above  named  species  is  found  besides 
along  the  upper  and  under  jaws;  as  for  the  upper  jaw,  however,  only  along  its  posterior 
portion;  the  mandibulary  line  of  pores  is  divided  into  two  parts.  The  ventral  tins  are 
located  immediately  behind  the  pectorals,  whose  length  is  nearly  3  times  as  great.  The 
short  first  dorsal  tin  begins  immediately  over  the  ventrals;  the  second,  longer  dorsal  fin 
and  the  anal  fin  have  an  equal  extent,  and  are  separated  somewhat  widely  from  the  caudal; 
both  are  very  low  in  their  posterior  half.

Gobioids  with  triangular  depressed  head,  narrow  mouth,  protractile  upper  jaw,  and  gill- 
opening  reduced  to  a  very  narrow  foramen  on  the  upper  surface  of  the  head.  Eyes  mod

This  form,  not  generally  recognized  by  the  Italian  ichthyologists,  is  supposed  to  occur 
in  the  Mediterranean,  where  Bonaparte  obtained  the  specimen  figured  by  him.  Vaillant

CALLIONYMT'S  11IMANTOPHORUS,  Goode  and  Bean,  u.  s.     (Figures  268, 268,  A.  B.) 

The  body  is  slender,  moderately  elongate,  the  fins  are  all  well  developed,  the  tail  taper- 
ing and  with  some  of  its  rays  produced  into  a  filament.  The  greatest  depth  is  at  the  head 
and  the  anterior  portion  of  the  trunk.  The  depth  of  the  head  equals  the  length  of  its  post- 
orbital  portion  and,  also,  the  greatest  depth  of  the  body.  The  caudal  peduncle  is  very  slen- 
der, the  least  height  of  the  tail  being  scarcely  more  than  one-fourth  the  greatest  height  of 
the  body.    The  profile  descends  very  rapidly  at  the  snout.      The  mouth  is  small  and  the

intermaxilla  is  \c\\  protractile,  but  may  be  almosl  entirely  concealed  under  the  preorbitals. 
The  intermaxilla  reaches  to  the  fronl  of  the  orbit.  The  maxilla  is  a  roundish,  slender  bone, 
extending  backward  to  the  end  of  the  intermaxilla.  The  mandible  is  about  as  Long  as  the 
eye;  it  extends  in  the  vertical  through  the  front  of  the  pupil.  Teeth  in  villi  form  hands  mi 
the  intermaxillary  and  mandible.  The  interorbital  spare  is  \crv  narrow,  less  than  a  fourth 
of  the  length  of  the  eye,  which  is  l.\  times  as  long  as  the  snout  and  nearly  one  eighth  of  the 
total  wit  liout  caudal.  The  length  of  the  head  to  the  gill-opening  is  two-sevenths  of  the  total 
without  caudal.  There  is  a  strong  bifurcated  spine  at  the  angle  of  the  preoperculum  ex- 
tending backward  slightly  beyond  the  gill-opening;  the  length  of  this  spine  at  its  upper 
articulation  is  two  thirds  the  length  of  the  eye.  The  gill-opening  is  reduced  to  a  small  slit, 
placed  at  a  distance  behind  the  eye  about  equal  to  the  length  of  the  eye  and  above  the  median 
line  of  the  body.  Skin  naked.  The  lateral  line  is  abruptly  arched  over  the  gill-opening 
and  is  connected  across  the  nape  with  its  fellow  of  the  opposite  side. 

The  spinous  dorsal  is  somewhat  elevated  in  front;  the  first  spine  is  nearly  twice  as 
long  as  the  last,  its  length  being  about  one-fifth  of  the  total  length  without  caudal.  The 
sixth  and  seventh  rays  are  the  longest,  their  length  nearly  equaling  that  of  the  base  of  the 
fin.  The  caudal  consists  of  four  simple  and  eight  divided  rays.  Of  the  divided  rays  in 
the  specimen  described  the  fifth  and  sixth  are  the  longest,  the  lower  portion  of  the  tilth 
and  the  upper  portion  of  the  sixth  being  produced  into  a  filament,  making  these  rays  as  long 
as  the  distance  from  the  tip  of  the  intermaxillary  to  the  fourth  anal  ray.  It  is  worthy  of 
remark  that  in  another  example  of  the  same  species  and  of  about  the  same  size  as  the  type 
the  sixth  of  the  divided  rays  alone  contributes  to  form  the  filament;  and  in  a  young  exam 
pic.  one  about  one-third  as  large  as  the  type,  the  first  dorsal  spine  when  laid  back  reaches 
to  the  cud  of  the  soft  dorsal.  Some  of  the  numerous  examples  of  this  species  have  none  of 
the  caudal  rays  much  produced,  even  in  large  individuals.  The  anal  fin  begins  directly 
under  the  third  ray  of  the  soft  dorsal;  its  rays  increase  in  length  to  the  sixth,  which  is  the 
longest  and  twice  as  long  as  the  first,  its  length  being  contained  five  and  two-thirds  times 
in  the  total  without  caudal.  All  the  rays  are  simple  except  the  last,  which  is  divided.  The 
pectoral  begins  under  the  middle  of  the  spinous  dorsal  and  extends  to  below  the  fifth  ray  of 
the  soft  dorsal;  its  rays  are  all  simple.  The  ventral  base  overlaps  the  lower  extremity  of 
the  pectoral  base/ its  origin  is  under  the  gill-opening.  The  fourth  and  longest  ray  equals 
one-fifth  of  the  total  length  without  caudal.     There  is  a  small  but  distinct  anal  papilla. 

Radial  formula:  D.  iv,  8;  A.  8;  P.  19;  V.  I,  5. 

Color,  generally  light  brown,  the  back  with  numerous  narrow  streaks  and  blotches  of 
slightly  darker  brown.  A  dark  blotch  on  the  membrane  between  the  third  and  fourth  dor- 
sal spines,  in  some  cases  occupying  nearly  all  of  the  membrane;  in  other  eases  more  limited 
and  nearly  elliptical  in  shape.  Anal  with  a  broad  subvertieal  dark  band,  the  tips  of  the 
rays  and  a  small  area  of  the  membrane  behind  each  ray  pale.  The  lower  caudal  lobe  with 
a  narrow  submarginal  dark  bind.  Ventral  with  two  indistinct  narrow  dark  bands  on  its 
outer  half. 

Specimens  of  this  species  were  obtained  by  the  Blake  from  station  XXX,  off  Barbadoes, 
at  a  depth  of  209  fathoms;  station  CLXXX,  in  24°  17'  30"  N.  Int.,  82°  09'  W.  Ion.,  at  a

Body  moderately  elongate,  covered  with  rudimentary  scales ;  head  scalcless,  without 
cirri,  compressed,  narrowed  above,  the  profile  strongly  decurved;  mouth  wide,  oblique; 
premaxillary  noi  protractile;  jaws  with  very  strong  conical  canines  anteriorly ;  lateral  teeth 
of  lower  jaw  either  molar  or  with  pointed  tubercles;  upper  jaw  withoul  lateral  teeth:  vomer 
extremely  thick  and  solid,  with  2  series  of  coarse,  molar  teeth;  palatines  with  1  or  2  similar 
series.  Grill-membranes  broadly  joined  to  the  isthmus;  no  lateral  Hue.  Dorsal  fin  rather 
high,  composed  entirely  of  flexible  spines,  which  are  enveloped  in  the  skin;  anal  fin  lower; 
caudal  lin  developed,  tree  from  dorsal  and  anal;  no  ventral  fins;  pectoral  fins  broad,  placed 
low;  air-bladder  present;  no  pyloric  ececa.     [Jordan  and  Gilbert.) 

A  key  to  the  species  of  Ana/rrhiehas,  prepared  by  Dr.  Bean,  is  given.  In  this  no  ref- 
erence is  made  to  A.  denticulatus  of  Kroyer,  because  the  slight  descriptions  which  we  have 
of  this  species  do  uot  serve  to  distinguish  it  from  A.  latifrons.  The  species  known  ou  the 
American  coast  as  A.  latifrons  is  evidently  the  latifrons  of  Steenstrup1  and  Collett,2  and  we 
cau  not  see  that  it  differs  from  A.  denticulatus  of  Giiuther3  or  of  Kroyer.4 

KEY  TO  THE  SPECIES  OF  ANARRHICHAS. 

A.  Banded  species.

302  DEEP-SEA   FISHES   OF   THE   ATLANTIC    BASIN. 

A  resident  of  the  deep  waters  in  200  to  400  fathoms  on  the  offshore  banks.  Many 
specimens  have  been  received  from  the  halibut  schooners,  and  it  has  been  taken  in  100 
fathoms  off  Finmark. 

The  Albatross  obtained  it  from  station  2429,  in  42°  55'  30"  N.  lat.,  50^  51'  W.  long.,  at 
a  depth  of  471  fathoms,  and  the  National  Museum  has  a  specimen  (Cat.  No.  21845)  taken 
by  one  of  the  Gloucester  fishing  vessels  in  1878  on  the  fishing- banks. 

Family  PTILICHTHYID^E. 

Ptilichthyinm,  Jordan  and  Gilbert,  Bull,  xvi,  U.  S.  Nat.  Mus.,  369  (subfamily  of  Maatacembelidtr). 
PtilichthyidcB,  Gill,  Standard  Nat.  Hist.,  vm,  1885,  259;  Century  Dictionary,  4827. 

Acanthopterygians  with  very  elongate,  anguilliform  body,  tapering  to  a  point;  small 
head,  mouth  oblique,  with  projecting  lower  jaw;  branchial  apertures  restricted;  dorsal  very 
long,  with  about  00  spines  and  145  rays;  anal  long  and  ventrals  absent.  Scales  none. 
Gill-membranes  broadly  united. 

PTILICHTHYS,  Bean.

Bull,  xvi,  U.S.Nat.Mns.,  369. 

Body  elongate,  serpentiform,  apparently  covered  with  very  thin,  scattered  scales. 
Mandible  little  movable,  projecting,  with  a  skinny  appendage  at  tip.  Cleft  of  the  mouth 
narrow.  Minute  teeth  in  a  single  series  in  the  jaws,  becoming  larger  and  slightly  curved 
posteriorly.  Margin  of  the  upper  jaw  formed  entirely  by  the  intermaxillaries.  Maxilla 
curved  forward  below.  The  gill  opening  extends  up  to  the  middle  of  the  base  of  the  pec- 
toral; the  membrane  is  slightly  einargiuate  behind  and  is  free  from  the  isthmus;  4  gills,  a 
slit  behind  the  fourth.  Gill-rakers  stout  and  short,  moderate  in  number.  Spinous  portion 
of  the  dorsal  consisting  of  many  isolated  spines,  a  narrow  membrane  behind  each.  Soft 
dorsal  and  anal  with  many  rays.     End  of  the  tail  free.     Neutrals  none. 

The  type  species,  Ptilichthys  <li>t»lri  (Figure  304),  was  taken  near  the  Aleutian  Islands. 
Everything  seems  to  indicate  that  it  is  an  inhabitant  of  deep  water.

men,  **32  millimeters  in  length,  was  presented  by  Oapt.  William  H.  Greenleaf  and  the  crew 
of  the  schooner  Chester  R.  Lawrence,  who  secured  it  on  the  Grand  Banks. 

The  dentition  of  the  La  Have  specimen  agrees  exactly  with  that  of  L.  Verrillii.  The 
lower  jaw  has  the  teeth  in  two  series,  with  an  imperfect  series  of  smaller  ones  between.  The 
upper  jaw  has  a  single  series  of  teeth,  with  a  few  smaller  ones  behind  the  symphysis.  There 
are  about  seven  teeth  on  the  vomer  and  a  single  row  of  about  seven  on  each  palatine.  The 
teeth  are  obtuse-conic,  not  curved,  as  in  L.  Verrillii.  In  the  specimen  of  L.  EsmarMi  from 
La  Have  the  colors  are  somewhat  less  regular  in  distribution  than  those  described  and  fig- 
ured by  Bernhardt;  instead  of  showing  (i  light  bands,  the  arrangement  of  light  color  upon  the 
dark  ground  of  the  body  is  as  follows:  One  white  spot  on  each  side,  above  the  posterior  end 
of  the  opercular  flap,  the  spots  not  meeting  on  the  dorsal  line.  The  first  saddle -shaped 
marking  begins  on  the  back,  under  the  eighth  ray  of  the  dorsal  fin,  and  extends  on  either 
side  nearly  to  the  middle  of  the  body.  The  second  saddle-shaped  marking  begins  under  the 
twenty- seventh  dorsal  ray  and  extends  nearly  to  the  margin  of  the  fin,  involving  the  width 
of  about  two  rays  and  the  connecting  membrane,  and  extends  also  downward  nearly  to  the 
middle  line  of  the  body,  increasing  iu  width  as  it  descends.  The  next  begins  under  the  fifty- 
fourth  ray,  and  resembles  the  last  in  form  and  extent.  The  next  begins  under  the  seventy- 
ninth,  and,  though  smaller,  resembles  the  others.  The  individual  from  the  Grand  Banks  is 
the  largest  yet  recorded.    The  measurements  are  as  follows:

The  greatest  height  of  the  body  tat  the  pectorals)  is  contained  8  times  and  its  greatest 
width  (just  behind  the  pectorals)  9  times  in  the  total  length.  The  width  at  the  vent  is  con 
tained  8  times  in  the  length  of  the  head  and  twice  in  the  length  of  the  longest  dorsal  ray. 
The  height  at  the  ventrals  about  equals  the  height  of  the  body  at  the  pectorals.  The  height 
of  the  body  at  the  vent  equals  half  the  greatest  width  of  the  head,  and  is  contained  Hi 
times  in  the  total  length. 

The  head  is  very  large,  its  length  being  -^  of  the  total,  and  its  greatest  width  contained 
5£  times  in  the  whole  length.  The  distance  from  the  tip  of  the  snout  to  the  nape  is  one- 
fifth  of  total  length,  and  four-thirds  of  the  length  of  the  mandible.  The  distance  between 
the  eyes  is  contained  6  times  in  the  length  of  the  head.  The  length  of  the  snout  is  one-third 
of  the  length  of  the  head.  The  nostrils  arc  much  farther  from  the  eyes  than  from  each  other, 
their  distance  from  the  eyes  being  contained  4.',  times  in  the  length  of  the  head.  The  length 
of  the  upper  jaw  is  contained  6|  times  in  the  total  length;  of  the  lower  jaw,  C<~  times;  the 
upper  jaw  slightly  exceeding  tin'  mandible  in  length.  The  eyes  are  very  small,  close  together, 
and  high,  their  long  diameter  being  equal  to  one-eleventh  of  the  length  of  the  head. 

The  distance  from  the  tip  of  the  snout  to  the  beginning  of  the  dorsal  fin  is  contained  3£ 
times  in  the  total  length.  The  first  ray  of  the  dorsal  is  contained  5|  times  in  the  length  of 
the  head,  and  the  longest,  4  times. 

The  distance  of  the  anal  from  the  snout  is  eleven-twentieths  of  the  total  length  and 
almost  equals  twice  the  distance  of  the  pectoral  from  the  snout.  The  first  anal  ray  is  con- 
tained 9.',  times  in  the  length  of  the  head,  the  longest  4.\  times.  The  vent  is  nearly  in  the 
middle  of  the  total  length. 

The  distance  from  the  tip  of  the  snout  to  the  base  of  the  pectoral  is  contained  3i  times, 
and  the  length  of  the  pectoral  6|  times  in  total  length.  The  length  of  the  pectoral  equals 
that  of  the  mandible,  and  only  slightly  exceeds  one  half  of  the  length  of  the  head. 

The  distance  of  the  ventral  from  the  tip  of  the  snout  equals  the  length  1  if  the  head.  The 
length  of  the.  ventral  equals  the  long  diameter  of  the  eye. 

Radial  formula:  D.  (including  half  of  caudal)  90;  A.  (including  half  of  caudal)  71;  P. 
18;  V.  3. 

Colors:  These  agree,  in  the  main,  so  closely  with  Richardson's  description  of  them,  that 
it  is  unnecessary  to  say  more  than  that  the  cross-markings  are  faint  and  narrow. 

The  gape  of  the  mouth  is  very  wide.  The  character  and  arrangement  of  the  teeth  agree 
perfectly  with  the  original  description. 

A  single  individual,  17  inches  long,  of  this  species,  originally  described  from  Northum- 
berland Sound,  was  found  by  Lieut.  Mintzer,  and  presented  by  him  to  the  TJ.  S.  National 
Museum.

Color,  brown  above,  yellowish  below. 

The  type,  41  millimeters  long,  was  obtained  in  the  Hardanger  Fiord,  Norway,  at  a  depth 
of  100-150  fathoms,  in  September,  1809,  by  Prof.  Sars.     The  specimen  was  immature. 

LYCODES  ZOAKCHUS,  Goode  and  Bean,  n.  s.  (Figures  276,  276  A  (young),  283  C). 

The  greatest  height  of  the  body,  10  millimeters,  is  about  one-ninth  of  the  total  length; 
it  is  entirely  covered  with  conspicuous  imbedded  scales  which  extend  behind  the  dorsal  and 
anal,  leaving  only  a  narrow,  naked  margin  around  these  fins.  Head-  and  pectorals  naked. 
A  lateral  line  begins  slightly  above  the  upper  angle  of  the  gill-opening,  rapidly  carving 
downward  and  extending  along  the  lower  part  of  the  body  not  far  from  the  base  of  the  anal 
fin;  it  can  be  traced  above  the  anterior  two-thirds  of  the  anal. 

The  length  of  the  head,  (iO  millimeters,  is  contained  Dearly  5§  times  in  the  total.  Its 
greatest  height,  32  millimeters,  equals  about  one  half  its  length.  The  iuterorbital  distance, 
measured  on  the  bone,  is  only  one-fourth  of  the  length  of  the  eye.  The  length  of  the  eye, 
15  millimeters,  is  nearly  one-fourth  the  length  of  the  head  and  is  equal  to  the  length  of 
the  snout.  The  nostrils  are  placed  close  to  the  upper  lip  ami  as  far  from  each  other  as 
from  the  eye.    The  maxilla  reaches  to  the  vertical  through  the  middle  of  the  eye. 

The  length  of  the  upper  jaw,  28  millimeters,  is  contained  2J  times  in  that  of  the  head. 
The  length  of  the  mandible,  31  millimeters,  is  nearly  one-half  that  of  the  head.  The  man- 
dible has  a  conspicuous  flap  on  each  side,  about  as  long  as  the  eye,  beginning  at  a  distance 
from  the  symiphysis  equal  to  one-half  the  length  of  the  eye.  The  inner  edge  of  the  man- 
dible also  has  a  slightly  elevated  ridge  of  skin.  Length  of  intermaxillary  series  of  teeth, 
13  millimeters,  equal  to  one-fifth  of  that  of  the  head.  Length  of  palatine  scries,  12  milli- 
meters, nearly  equal  to  that  of  intermaxillary.  Vomerines  in  a  round  patch.  Mandibular 
teeth  in  three  series.  Width  of  gill-opening,  25  millimeters,  two-fifths  length  of  head.  The 
ventrals  are  in  front  of  the  base  of  the  pectorals;  their  length,  s  millimeters,  equals  one- 
eighth  that  of  the  head.  The  distance  between  the  lower  angles  of  the  gill-opening,  12  mil- 
limeters, is  nearly  one  fifth  the  length  of  the  head.  The  origin  of  the  dorsal  is  distant  from 
the  head  a  space  equal  to  one-third  the  length  of  the  head;  it  is  slightly  behind  the  middle 
of  the  pectoral.  The  pectoral  when  extended  reaches  to  about  the  vertical  from  the  sixth 
dorsal  ray.  The  longest  ray  of  the  dorsal  is  about  one  fourth  the  length  of  the  head.  The 
anal  orginates  under  the  seventeenth  ray  of  the  dorsal.  The  vent  is  under  the  fifteenth 
ray  of  the  dorsal.  The  longest  pectoral  ray,  38  millimeters,  is  contained  about  9£  times  in 
the  total  length. 

Color,  grayish-brown,  lighter  on  the  belly  and  under  surface  of  the  head;  sides,  irregu- 
larly mottled  with  darker,  a  narrow  dark  edge  at  the  tip  of  the  first  four  dorsal  rays. 

In  a  youug  specimen,  No.  39299,  the  mottlings  on  the  sides  are  band-like,  the  bands  not 
extending  below  the  middle  of  the  body  entirely.  This  example  is  from  N.  lat.  11°  20',  W. 
Ion.  57°  11'  15",  190  fathoms.

The  type  of  the  description  is  a  specimen  366  millimeters  long,  catalogue  number  39298, 
obtained  by  the  Albatross  in  X.  lat,  MP  46'  30",  W.  Ion.  59°  55'  45",  130  fathoms,  off  Nova 
Scotia.  This  species  has  the  same  number  of  rays  in  the  dorsal  and  anal  as  in  some 
specimens  of  L.  paxillus,  but  the  pectoral  has  1!)  rays  instead  of  16,  the  median  lateral- line 
is  not  developed  as  hi  paxillus,  and  the  form  is  very  much  stouter,  the  greatest  height  in

paxillus  being  only  a  fifteenth  <>!'  the  total  length,  while  in  zoarchus  it  is  one-ninth.  The 
head  in  pcucillus  is  one  seventh  of  the  total  length,  while  in  this  species  its  Length  is  con 
tained  5jj  times.  The  coloration  is  also  very  different  from  thai  of  paxillus,  t  lie  la  iter  being 
a  uniform  brown,  while  zoarchus  has  a  black  blotch  at  the  beginning  of  the  dorsal,  and  the 
sides  are  irregularly  mottled  with  dark  markings,  which  in  the  young  specimen  form  more 
or  less  complete  bands,  while  iii  adult  specimens  these  bands  break  up  into  irregular 
mottlings.

Lateral  line  present,  but  difficult  to  trace  in  its  entirety.  From  the  upper  angle  of  the 
gill-opening  a  series  of  rather  closely  placed,  very  small  pores  (connected  by  a  narrow  line), 
descends  in  a  curve  to  a  short  distance  behind  the  vent;  after  having  reached  nearly  to  the 
base  of  the  anal,  it  runs  for  a  short  distance  nearly  horizontally,  whereupon  it  ceases,  or 
can  not  be  followed  in  the  same  direction  with  certainty.  Another  lateral  line,  however, 
begins  about  over  the  vent,  and  runs  horizontally  along  the  median  line,  becoming  obsolete 
toward  the  end  of  the  tail.  The  pores  herein  are  very  small  and  more  widely  separated,  and 
can  be  seen  only  by  close  observation ;  the  short  whitish  line  which  runs  through  each  pore, 
forms  here  no  accompanying  line. 

Since  the  termination  of  the  anterior  descending  lateral  line  is  considerably  behind  the 
origin  of  the  upper  horizontal  lateral  line,  no  connection  appears  to  exist  between  them.

310  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

Color,  light  grayish  brown  above;  below,  pearly  white;  sides  with  irregular  brown 
patches  bisected  by  the  lateral  line;  abdominal  region  livid  blue;  a  spot  of  brown  on  the 
tip  of  the  tail. 

L.  Verrillii  proves,  as  we  have  long  believed  it  to  be,  a  pygmy  species,  reaching 
maturity  at  a  length  of  from  5  to  (1  inches.  The  old  males  are  transformed  almost  beyond 
specific  recognition  by  an  extraordinary  development  of  the  entire  head  in  advance  of  the 
eyes.  The  snout  becomes  shovel-shaped,  its  length  equal  to  two-fifths  that  of  the  head, 
while  in  the  normal  condition  it  is  only  one-fourth.  We  have  examined  specimens  in  inter- 
mediate condition.  The  extension  of  the  snout  is  accompanied  by  a  corresponding  enlarge- 
ment of  the  muscles  of  the  cheeks.

l/ycenchelys  paxillue,  Jordan,  Cat.  Fish.  N.  Amer.,  1885,  124. 
Ly codes paxilloides,  Goode  and  Bean,  Bull.  Mns.  Comp.  Zool.,  1883,  x,  No.  5,  207-8  (a  normal,  not  sexually 

distiii led.  individual). 

Body  attenuate,  its  greatest  height  about  half  the  length  of  the  head,  which  is  broad 
flat  above,  with  declivous  profile;  its  length  contained  about  eight  times  in  that  of  body. 
Upper  jaw  extending  far  beyond  thelower;  cheeks  very  full  and  protuberant.  Teeth  stout, 
recurved,  and  sharply  pointed,  in  a  single  series  on  both  jaws,  except  at  the  symphysis;  a 
few  teeth  clustered  at  the  head  of  the  vomer;  palatines  with  a  single  series;  interorbital 
space  about  one-fourth  length  of  snout,  which  is  about  equal  to  that  of  eye,  which  is  con- 
tained 34  times  in  length  of  head.  The  tubular  nostril  is  much  nearer  to  the  tip  of  the 
snout  than  to  the  eye. 

Origin  of  dorsal  over  end  of  the  extended  pectoral;  its  distance  from  the  tip  of  the 
snout  is  contained  4  to  if  times  in  the  total  length ;  that  of  the  anal  from  the  snout  .'i*.  times 
or  less.  Vent  immediately  in  front  of  anal.  The  length  of  the  pectoral  equals  one-half  that 
of  the  head,  or  a  little  more.  The  distance  of  the.  ventral  from  the  snout  is  contained  84 
times  in  the  total  length.  The  length  of  the  ventral  is  scarcely  more  than  that  of  the 
pupil.  Scales  very  small,  present  everywhere  except  on  the  head  and  pectorals,  extending 
almost  out  t<>  the  margin  of  the  vertical  tins. 

Eadial  formula:  I).  11G;  A.  100. 

Color,  light  brown,  the  head  somewhat  darker. 

The  form  of  L.  paxillus  is  rounder  and  more  terete  than  that  of  almost  any  other 
described  species.  It  is  also  easily  distinguished  by  its  very  short  head,  by  the  peculiar 
curvature  of  the  strong  jaw.  and  by  the  enormous  development  of  the  muscles  of  the  cheek, 
in  the  small  number  of  pectoral  rays  it  resembles  L.  polaris,  Sabine,  L.  murcena,  Collett, 
and  L.  Verrillii,  Goode  and  Bean. 

The  type  of  L.  paxillus  is  a  male  in  breeding  form,  such  as  is  shown  in  figure  279. 

L.  paxilloides  was  based  upon  a  normal  individual,  as  shown  in  figure  282. 

The  first  example  of  this  form  was  obtained  by  ('apt.  Joseph  W.  Collins  and  the  crew 
of  the  schooner  Marion  of  Gloucester,  from  the  gully  between  Le  ITave  and  Sable  Island 
Banks,  in  lat.  42°  48'  N.,  Ion.  63°  07'  W.,  and  presented  to  the  U.  S.  Fish  Commission  for 
the  National  Museum.  The  specimen,  which  is  143  inches  in  length,  is  in  a  dilapidated 
condition,  and  was  apparently  taken  from  the  stomach  of  a  fish,  probably  a  halibut.  Fish- 
ing in  this  locality  is  carried  on  exclusively  with  trawls  or  long-lines  at  a  depth  of  1,200  to 
2,400  feet.

LYCODONUS,  Goode  and  Bean. 

Lycodonii*.  Goode  and  Bean,  Bull.  Mus.  Comii.  Zool.,  x,  No.  5,  208. — Gunther,  Challenger  Report,  xxn, 

1887,  81. 

Lycodoids  with  body  blenniform,  elongate.  Scales  small,  circular,  imbedded  in  the  skin. 
Lateral  line  very  short,  posteriorly  obsolete.  Eye  moderate.  Jaws  without  fringes.  Upper 
jaw  longer  than  lower.  Fin  rays  soft,  articulated;  those  of  the  dorsal  and  anal  tins  sup- 
ported laterally,  each  by  a  pair  of  sculptured  ectodermal  scutes  or  plates.  Caudal  distinct, 
not  fully  connate  with  dorsal  and  anal,  few-rayed.  Ventrals  present,  jugular,  each  com- 
posed of  a  few  slender,  deeply  cleft,  articulated  rays.  Gill  opening  rather  narrow. 
Branchiostegal  membranes  broadly  joined  to  the  isthmus.  Teeth  as  in  Lycodes.  Pseudo- 
branchiae  apparently  present.  Branchiostegals  apparently  5.  Gill  arches  4.  Gill-rakers 
rudimentary,  in  moderate  number.     Air  bladder  and  pyloric  caeca  apparently  absent. 

This  genus  is  in  nearly  every  particular  like  Ly codes,  from  which,  however,  it  is  dis- 
tinguished by  the  peculiar  structure  of  the  dorsal  and  anal  fins. 

LYCODONUS  MIRABILIS,  Goode  and  Bean.     (Figure  280.) 
Lyeodonus  miralilis,  Goode  and  I'.eax,  Hull.  Mus.  Comp.  Zool.,  1883,  x,  No.  5,  208,  209. 

The  body  is  shaped  much  as  in  Lycench  lys  Verrillii;  its  greatest  height,  at  origin  of  dorsal, 
contained  about  18  times  in  the- length  of  the  body.  Scales  as  in  Ly  codes,  the  scales  not 
extending  out  upon  the  tins.  The  head  and  nape  are  also  scaleless.  Lateral  line  appar- 
ently obsolete  posteriorly,  not  extending  back  of  the  extremity  of  the  pectoral. 

The  length  of  the  head  is  contained  about  7  times  in  the  entire  length.  The  diameter 
of  the  eye  is  contained  '2h  times  in  the  length  of  the  head,  and  is  about  equal  to  the  postor- 
bital  portion  of  the  head.  The  eye  is  placed  high,  the  width  of  the  interorbital  space 
being  less  than  the  diameter  of  the  pupil,  and  contained  3J  times  in  the  long  diameter  of 
the  eye.  Nostrils  immediately  in  front  of  the  eye.  The  maxilla  extends  to  the  vertical 
through  the  anterior  margin  of  the  pupil;  the  mandible,  to  a  little  behind  the  vertical 
through  the  posterior  margin  of  the  pupil. 

The  dorsal  tin  is  inserted  slightly  behind  the  vertical  through  the  base  of  the  pectoral; 
the  portion  of  the  tin  present  in  the  mutilated  specimen  before  us  contains  iSO  articulated 
rays.  The  first  10  or  11  scutes  do  not  support  rays,  but  whether  rays  were  originally  present 
or  not  can  not  be  ascertained.  The  longest  dorsal  ray  is  about  equal  to  the  longest  anal 
ray,  its  length  being  contained  about  3  times  in  that  of  the  head.  The  distance  of  the 
vent  from  the  snout  is  twice  the  length  of  the  head;  the  anal  begins  immediately  behind 
the  vent;  it  consists  at  present  of  about  70  articulated  rays.  The  caudal  rays  extend  be- 
yond the  tips  of  the  ultimate  dorsal  and  anal  rays;  they  are  about  9  in  number. 

The  distance  of  the  ventral  from  the  snout  is  equal  to  twice  the  length  of  the  upper  jaw; 
middle  ventral  ray  is  the  longest,  it  being  half  as  long  as  the  postorbital  part  of  the  head. 

The  length  of  the  pectoral  equals  three  times  that  of  the  snout. 

Eadial  formula:  D.  S0+ ;  A.  70+;  C.  9;  P.  18;  Y.  3. 

A  single  mutilated  specimen,  measuring  112  millimeters  in  its  imperfect  condition,  was

Gymnelis pictu8,  GtJNTHER,  Cat.  Fish.  Brit,  Mus.,  IV,  1862,  324. 

Height  of  body  one-half  the  length  of  the  head,  which  is  contained  about  0J  times  in 
the  total  length;  snout  subcorneal,  longer  than  the  eye;  jaws  equal;  mouth  oblique;  maxillary 
reaching  beyond  eye;  teeth  rather  small,  conical,  in  a  single  series  on  each  side,  forming  a 
patch  anteriorly;  distance  from  snout  to  vent  2J  times  length  of  head. 

Pectoral  rounded,  inserted  low,  its  length  less  than  half  that  of  the  head.     Dorsal  com 
mencing  over  posterior  third  of  pectorals. 

Radial  formula:  D.  100;  A.  80. 

Color,  brownish,  usually  with  dark  transverse  markings,  but  sometimes  unspotted. 

This  species  has  been  found  in  abundance  in  the  Arctic  seas,  from  Alaska  to  Nova  Scotia. 

MELANOSTIGMA,  Gunther. 

Melanostigma,  GOnther,  Proc.  Zool.  Soc.  London,  lssi,  20;  Challenger  Report,  xxn,  1877,82. 

This  genus  agrees  with  Gymnelis  and  Maynea  in  the  absence  of  ventral  fins,  and  tech 
nically  may  be  distinguished  from  both  by  the  much  more  elongate  teeth,  which  in  the  jaws, 

as  well  as  on  the  vomer  and  palatines,  stand  in  a  single  scries.  However,  there  are  other 
striking  differences,  which  will  be  mentioned  in  the  subsequent  description.

1885,  125. 

Body  is  enveloped  in  a  loose,  delicate  skin,  as  in  Liparis.  Head  large,  deep,  compressed, 
with  obtuse  snout.  Eye  large,  two-sevenths  of  the  length  of  the  head  and  longer  than  tin- 
snout.  Cleft  of  the  mouth  rather  oblique,  but  the  lower  jaw  does  not  project  beyond  the 
upper.  Lips  not  fleshy.  Inside  of  the  mouth,  gill-openings,  and  vent  black.  The  gill- 
opening  is  reduced  to  a  very  narrow  foramen  above  the  base  of  the  pectoral  fin.  The  origin 
of  the  dorsal  fin  and  the  root  of  the  pectoral  arc  enveloped  in  the  loose  skin  of  the  body. 
The  dorsal  fin  seems  to  commence  above  the  middle  of  the  pectoral,  is  low  at  first,  but 
becomes  considerably  higher  posteriorly.  Pectorals  very  narrow,  consisting  of  a  few  rays 
only.  Upper  parts  tinged  with  a  purplish  gray;  sides  marbled  with  the  same  color,  v>  hich 
toward  the  end  of  the  tail  becomes  more  intense,  almost  black. 

Total  length  of  the  specimen  5|  inches;  distance  of  the  snout  from  the  gill-opening 
seven-eighths  inch,  from  the  vent  1;  inches. 

The  type  specimen  was  obtained  on  January  L6,  1880,  by  l>r.  Coppinger,  of  II.  M.  S.

Color,  blackish,  sometimes  with  a  reddish  tint. 

This  form  is  very  rare,  having  been  recorded  only  from  the  Mediterranean  off  Nice, 
where  it  lives  at  considerable  depths,  approaching  the  shores  in  August  to  deposit  itseggs 
in  the  crevices  of  rocky  ledges.  It  is  not  positively  known  to  inhabit  the  region  beyond 
the  hundred-fathom  Hue. 

Giinther  has  studied  the  lateral  line  in  a  single  specimen,  lately  acquired  by  the  Brit- 
ish Museum,  and  reports  that  it  is  rather  indistinct  and  interrupted,  and  that,  in  his  judg- 
ment, the  fact  that  the  ends  of  the  two  portions  overlap  each  other  has  given  rise  to  the 
statement  that  the  lateral  line  is  double  along  a  portion  of  the  tail.

CATiETYX    MESSIERI. 

This  genus  is  represented  by  two  species,  Catcetyx  Messieri,  loc.  cit.,  pi.  xxin,  Fig.  B, 
obtained  by  the  Challenger  in  Messier  Straits  (Station  306  A),  at  a  depth  of  345  fathoms. 

The  Albatross  took  four  specimens  of  another  form,  Catcetyx  rubrirostris,  in  205-35$, 
fathoms  off  the  coast  of  California.

Body  compressed,  little  elongate,  partly  invested  by  minute,  membranous,  non-imbri- 
cated scales.  Abdomen  large.  Head  with  loose,  scaleless  skin.  Snout  a  little  inflated,  not 
projecting  beyond  the  equal  jaws.  Bones  of  the  head  firm,  without  spines,  the  mucous 
channels  well  developed,  but  without  conspicuous  external  openings.  Opercles  unarmed. 
No  barbels.  Eyes  small.  Mouth  wide.  Bands  of  villiform  teeth  in  jaws,  palatines,  and

Represented  by  Sacoogaster  maculatm,  Alcock  (he.  cit.),  from  103  fathoms,  Bay  of  Ben- 
gal, lat.  20°  17'  30"  N.,  Ion.  88°  50'  E.,  and  from  stations  120  of  the  Investigator,  in  240-276 
fathoms. 

The  name  Saeeogastrr,  which  alludes  to  the  distended  abdomen,  was  based  upon  the  ap- 
pearance of  the  type  described  in  1881),  which  Alcock  has  since  found  to  contain  distended 
ovaries,  full  of  developing  embryos.  Sacoogaster  is  viviparous,  and  the  males  have  been 
found  to  have  a  postanal  papilla  which  serves  as  an  intromittent  organ.

(Off  Soudan). 

The  greatesl  depth  of  the  body  is  below  the  origiu  of  the  dorsal  11  n,  and  contained  twice 
and  one-third  in  the  distance  of  the  extremity  of  the  snout  from  the  vent.  The  head  is 
aliout  as  deep  as  broad, its  Length  being  equal  to  the  distance  of  the  vent  from  the  root  of 
the  ventral  tins,  and  more,  than  one-half  of  the  Length  of  the  body  exclusive  of  the  tail.  The 
vent  is  nearer  to  the  snout  than  to  the  root  of  the  caudal.  Eye  of  moderate  size,  without 
orbital  fold,  as  long  as  thesnout,  one-fifth  of  the  Length  of  the  head  and  equal  to  tlie  width 
of  the  flat  interorbital  space.  Mouth  of  moderate  width,  the  maxillary  extending  somewhat 
behind  the  eye  and  being  slightly  dilated  behind.  All  the  teeth  are  in  narrow  villit'orin 
bands,  that  of  the  vomer  being  opeu  and  ^-shaped.  The  superficial  bones  of  the  head  are 
thin,  and  those  of  the  infraorbital  ring  and  of  the  mandible  dilated  for  the  reception  of  the 
wide  mucous  canals.  Of  the  opercular  spines  the  horizontal  is  remarkably  Long,  much 
Longer  than  the  lower  vertical  one. 

The  vertical  lins  are  completely  united,  and,  owing  to  the  great  attenuation  of  the  tail, 
no  caudal  portion  can  be  distinguished.  The  rays  are  very  thin,  closely  set,  and  of  mod- 
erate length.  Origin  of  the  dorsal  tin  immediately  behind  the  root  of  the  pectoral,  and 
that  of  the  anal  immediately  behind  the  vent.  Pectoral  tins  rather  narrow,  inserted  on  a 
short,  broad,  and  partly  free  pedicle;  they  are  Longer  than  the  postorbital  portion  of  the 
head;  ventrals  half  as  long  as  the  distance  of  their  root  from  the  vent. 

The  scales  arc  rather  small,  thin,  cycloid,  and  rather  deciduous;  if  a  lateral  hue  is 
present,  it  is  confined  to  the  trunk. 

Upper  parts  of  a  uniform  light  brownish  color;  the  lower  parts  and  the  tins  colorless. 

The  type,  1A  inches  long,  was  taken  by  the  Challenger  off  Pernambuco,  Brazil  (station 
122),  in  350  fathoms.  Dr.  Alcock  has  identified  with  the  same  species  a  female  1A  inches 
long  with  gravid  ovaries,  taken  by  the  Investigator  in  the  Andaman  sea,  7J  miles  east  of 
North. Cinque  Island  in  190  fathoms  (=D.  Alcockii,  G.  &  B.     See  p.  523,  below). 

DICROMITA,  GOODE  and  Bean,  n.  g. 

Brotulids  resembling  in  form  and  general  appearance  Catcetyx  and  Diaplacanthopoma, 
having  the  lateral  line  obsolete,  or  interrupted  posteriorly;  ventrals  a  pair  of  simple,  tine 
filaments  ;  and  teeth  upon  the  palatines.  It  has,  however,  three  or  four  small  spines  upon 
the  preoperculum,  as  well  as  a  sharp  spine  upon  the  upper  angle  of  the  operculum;  and 
the  lateral  line,  though  indistinct,  is  traceable  for  half  or  three  fourths  the  length  of  the 
body,  which,  like  the  upper  part  of  the  head,  is  covered  with  small,  deciduous  scales,  the 
opercular  region  being  apparently  scaleless,  and  the  bones  of  the  suborbital  region  almost 
uncovered,  with  conspicuous  sinuses,  which  show  through  the  transparent  texture  of  the 
surface.  The  head  is  oblong,  the  snout  being  somewhat  produced,  depressed  and  turgid, 
resembling,  though  in  a  less  degree,  that  of  Barathrodemus.  Eye  moderate,  conspicuous. 
Mouth  wide;  teeth  villiform,  in  bands  on  the  jaws  and  palatines,  and  very  minute  upon  the 

v '>'•  which  has  a  roughened,  knob  like  enlargement   at  its  angle.    Vent   premedian. 

Vertical  fins  continent ;  ventrals  rooted  very  dose  together,  each  reduced  to  a  fine,  flexi- 
ble, simple  filament,  planted  somewhat  behind  the  isthmus  and  below  the  middle  of  the 
operculum,  dills  1,  with  well  developed  lamina'  and  rather  long,  slender  gill-rakers. 
Branchiostegals  8.    Pseudobranchise  apparently  absent. 

DICROMITA  AGASSIZH,  Goode  and  Bean,  n.  s.  (Figure  286). 

Body  elongate,  much  compressed,  its  height  about  one-fifth  of  its  total  length;  its 
width  about  half  its  greatest  height.  The  length  of  the  head  is  slightly  greater  than  the 
height  of  the  body,  ami  equal  to  twice  its  own  width.  Mouth  very  Large,  the  maxillary, 
which  is  curved  and  much  dilated  at  its  extremity,  reaching  far  behind  tin'  \ci  in  sal  from

the  posterior  margin  of  orbit.  Jaws  nearly  equal,  the  snout  being  considerably  produced 
and  dilated,  its  length  equal  to  the  diameter  of  the  eye  and  one  fourth  the  length  of  the 
head.  Teeth  very  fine,  villiform,  in  bands  on  jaws  and  palatines,  and  also  present  on 
vomer,  though  very  small,  especially  upon  the  rounded,  globular  process  at  the  angle. 
Lateral  line  very  indistinct,  interrupted,  but  extending  behind  the  vent  at  least  one-third 
of  the  way  to  the  tip  of  the  tail.  Dorsal  origin  nearly  in  vertical  from  the  axil  of  the  pec- 
toral; ventrals  very  slender,  villiform.  closely  approximate  at  their  roots,  and  less  than  half 
as  long  as  the  head. 

Color,  brownish. 

A  specimen  was  obtained  by  the  Blake,  off  Granada,  station  xciii,  at  a  depth  of  291 
fathoms.  This  specimen,  from  which  the  shaded  figure  was  made,  has  evidently  had  its 
tail  broken  off  and  the  damage  repaired.  The  collateral  type  was  obtained  by  the  Albatross 
at  station  2374,  in  29°  11'  30'  N.  lat.,  85°  29'  W.  Ion.,  at  a  depth  of  26  fathoms.

<>f  the  preoperculum,  hidden  under  the  skin. 

Vent  premedian,  separated  from  the  origin  of  the  ventrals  by  a  distance  slightly  greater 
than  the  length  of  the  head.  Origin  of  dorsal  slightly  behind  vertical  from  base  of  pectoral. 
Anal  origin  near  vent.  Pectorals  half  as  long  as  head,  simple.  Ventrals  reduced  to  a  pair 
of  simple  filaments  which  surpass  the  pectorals. 

Scales  small,  distinct,  not  so  deciduous  as  in  many  similar  forms,  about  151  in  longi- 
tudinal and  33  in  vertical  series.     Lateral  line  obsolete  in  its  posterior  half. 

Color,  grayish,  with  blackish  belly  and  darker  edges  to  the  vertical  tins. 

The  French  explorers  obtained  one  specimen  from  the  Banc  dArguin  (station  XCV), 
1,230  fathoms,  two  from  off  the  Azores  and  from  station  cxxi,  in  1,412  fathoms,  and  one  from

Body  moderately  compressed,  anguilliform,  its  height  one-thirteenth  of  its  total  length. 
Head  elongate,  its  length  one-fifth  that  of  the  body.  The  snout  is  four-elevenths  of  the 
head,  and  somewhat  spatulate.  The  upper  jaw  extends  somewhat  beyond  the  lower  one. 
Mouth  inferior,  half  as  long  as  the  head;  the  maxillary  passes  the  vertical  from  the  posterior 
margin  of  the  orbit.  Teeth  small,  in  villiform  bands  upon  the  jaws,  vomer,  and  palatines. 
Eye  very  small,  nearly  hidden  in  the  skin,  but  distinct;  its  diameter  about  one-twentieth 
that  of  the  head,  while  the  interorbital  space  is  one-fourth.  Branchial  opening  very  wide. 
Opercular  bone  indistinct.  The  preoperculum  has  four  strong  spines  at  its  angle;  the  oper- 
culum has  1  spine,  strong,  somewhat  curved  upward,  prominently  projecting.  Head  naked, 
except  upon  the  cheek  and  the  opercular  flap. 

Vent  at  a  distance  from  the  base  of  the  ventrals  greater  than  the  length  of  the  head. 
Scales  exceedingly  small,  scarcely  visible  to  the  naked  eye,  imbedded  in  the  skin,  more  dis- 
tinct in  the  veutral  region  than  on  the  rest  of  the  body;  lateral  line  represented  by  a  series 
of  inconspicuous  elevations,  which  are  not  noticeable  in  the  latter  half  of  its  length ;  it  is  near 
the  dorsal  outline. 


DISCUSSION    OP    SPECIES    AND    THEIE    DISTRIBUTION.  321 

Origin  of  dorsal  over  the  middle  of  pectoral;  that  of  the  anal  immediately  behind  the 
vein.  The  anal  (ins  arc  low.  The  pectoral  is  composed  of  L3  rays,halfas  Long  as  the  head, 
lanceolate,  tin-  two  lower  rays  detached  without  being  inure  developed  than  the  others. 
Ventrals  still  smaller  i  perhaps  mutilated  in  the  specimen  figured  1  >y  Yaillant ). 

Color  white,  except  bluish-black  upon  the  head  and  abdomen,  and  the  pectorals  a  deep 
brown. 

Three  specimens  were  obtained  by  the  French  Expedition  at  station  ci,  off  the  Cape 
Verde  Islands,  at  a  depth  of  3,200  meters.  The  fish  is  very  remarkable  by  reason  of  the 
smallness  of  its  e.vcs  and  the  peculiar  character  of  the  scales.

Sin  mho  onet  rocephalut,  Vaili.axt,  Exp.  Soi.  Travailleui  et  Talisman,  -77,  PI.  xxiv,  Fig.  <>. 

Body  elongate,  compressed,  its  height  one-ninth  and  its  thickness  one-third  of  its 
length.  Length  of  the  head  two  elevenths  of  the  length  of  the  body;  it  is  rounded.  Snout 
hemispherical,  occupying  three-elevenths  of  the  length  of  the  head  and  projecting  beyond 
the  mouth.  Mouth  moderate,  although  the  maxillary  extends  behind  the  eye;  the  mouth 
does  not  extend  to  the  middle  of  the  length  of  the  head.  The  two  jaws,  the  vomer,  and 
the  palatines  are  armed  with  line  teeth  in  villiform  bands.  Bye  small,  inconspicuous,  hid- 
den in  the  integuments,  its  diameter  one-fifteenth  of  the  length  of  the  head;  interorbital 
space  live  times  as  wide  as  the  diameter  of  the  orbit.  Branchial  opening  wide.  The  bones 
composing  the  opercular  tlap  are  hidden  in  the  mucous  integument  which  covers  the  head, 
and  indistinct;  only  one  flexible  spine  can  be  seen  on  the  operculum.  A  few  scales  upon 
the  vertex,  and  more  upon  the  jaws  and  opercular  flap.  Vent  at  a  third  of  the  distance 
from  the  snout  to  the  tail,  and  separated  from  the  origin  of  the  ventrals  by  a  distance  a 
liltle  greater  than  the  length  of  the  head.  Scales  very  minute,  imbricated;  no  lateral  line 
is  perceptible. 

The  origin  of  the  dorsal  is  a  little  in  advance  of  the  branchial  opening;  the  anal  im- 
mediately behind  the  vent,  both  quite  high  posteriorly,  their  height  nearly  half  that  of  the 
body.  Caudal  rays  prominent  (Vaillant  says  "assez  distincte,"  but  the  figure  shows  the 
vertical  tins  to  be  continent).  Pectorals  short,  a  little  more  than  half  as  long  as  the  head, 
composed  of  L'l  rays.     Ventrals  as  long  as  the  pectoral. 

Color,  pure  white ;  head  entirely  bluish-black,  as  is  also  the  abdomen,  though  not  so 
dark. 

A  single  specimen  was  obtained  by  the  French  explorers  from  station  ci,  off  the  Cape

Bassozetus  normalis,  Gill,  Proc.  U.  S.  Nat.  Mus.,  1883,  259. 

Body  much  compressed,  its  width  in  the  region  of  the  vent  not  more  than  one-third  of 
its  height,  which  at  the  same  point  is  about  one-ninth  of  the  total  length.  The  greatest 
height  of  the  body,  over  the  origin  of  the  pectorals,  is  about  two-thirds  the  distance  from 
the  base  of  the  pectorals  to  the  vent,  the  vent  being  about  twice  as  distant  from  the  base 
of  the  caudal  rays  as  from  the  snout.  Head  moderately  compressed,  Hat  above;  with  snout 
obtuse,  rounded,  turgid;  lower  jaw  considerably  included.  The  length  of  the  head  con 
tained  nearly  six  times  in  the  total  length. 

The  bones  of  the  head  not  completely  ossified,  very  cavernous  in  the  alcoholic  speci- 
men, the  head  showing  many  deep  sinuosities  and  depressions.  Eye  very  small,  its  diame- 
ter about  one-fourth  the  length  of  the  snout,  and  situated  about  midway  between  the  tip  of 
the  snout  and  the  vertical  from  the  posterior  end  of  maxillary.  Teeth  all  small  and  short, 
densely  set,  forming  narrow,  villiform  bands;  vomerine  band  open  V-shaped.  The  dorsal 
fin  begins  far  in  advance  of  the  origin  of  the  pectoral  and  above  the  upper  angle  of  the  gdl- 
opening;  the  rays  are  longest  in  the  region  over  the  vent.  The  anal  begins  immediately

Bathyonus  compnssus,  Gunther,  Challenger  Report,  xxn,  1887,  xxii.  Fig.  A. 

The  greatest  depth  of  the  body  is  above  the  end  of  the  gdl-cover  and  about  one-half  of 
the  length  of  the  trunk,  the  vent  being  twice  as  distant  from  the  extremity  of  the  tail  as 
from  the  snout;  consequently,  the  tail  is  but  moderately  attenuated.  Head  compressed 
like  the  body,  and  about  two-thirds  of  the  length  of  the  trunk ;  the  superficial  bones  form 
large  muciferous  cavities,  which,  when  full,  must  give  to  the  head  a  much  more  evenly 
rounded  appearance  than  in  the  preserved  state,  when  the  supporting  bony  ridges  project 
more  or  less  from  under  the  skin.  The  snout  is  slightly  swollen,  but  the  jaws  are  nearly 
even  in  front,  the  wide  mouth  slightly  ascending  forwards.  The  maxillary  has  the  form 
usual  in  these  Gadoid  fishes,  is  dilated  behind,  and  extends  far  behind  the  eye. 

The  eye  is  very  small,  one  half  of  the  length  of  the  snout,  and  about  one-eleventh  of 
that  of  the  head;  it  is  placed  up  on  the  side,  and  does  not  possess  an  orbital  fold  of  the 
integument.  The  interorbital  space  rather  convex,  and  equal  in  width  to  three  diameters 
of  the  eye. 

All  the  teeth  are  very  small  and  short,  densely  set,  and  form  villiform  bands.  The 
broadest  is  that  of  the  maxillary  bone,  and  it  is  quite  uncovered  on  the  sides,  no  labial  folds

being'  developed.  The  palatine  band  is  broader  than  the  inandibulary,  and  the  vomerine 
band  A-shaped,  each  arm  being  bent  with  the  convexity  inwards. 

Gill-opening  and  cavity  very  wide  and  of  an  intense  black.  The  gill  rakers  are  much 
longer  than  the  lamina',  15  in  number  on  the  anterior  arch,  besides  some  rudimentary  ones 
above. 

The  dorsal  tin  commences  above  the  upper  end  of  the  gill-opening,  with  short  rays 
partly  hidden  in  the  skin;  the  rays  become  longer  in  the  middle  of  the  tin,  but  remain  of 
moderate  length,  and  the  anal  rays  are  still  shorter.  The  pectoral  has  a  rather  narrow 
base,  is  quite  free,  and  composed  of  feeble  rays;  its  length  is  only  half  that  of  the  head. 
Ventral  rays  very  feeble,  reaching  somewhat  beyond  the  root  of  the  pectoral. 

Only  very  few  of  the  thin,  cycloid,  scales  have  been  preserved}  they  are  of  moderate 
size,  there  being  about  sixteen  in  a  transverse  series  running  from  the  vent  to  the  dorsal  tin. 
The  lateral  line,  if  it  was  developed,  can  no  longer  be  traced. 

Radial  formula:  D.  166;  A.  92;  P.  23;  V.  1.  Color,  blackish,  with  the  tins,  head,  and 
abdomen  black.     (Giintker.) 

The  species  was  obtained  by  the  Challenger  from  the  mid- Atlantic  in  1,501)  fathoms 
(station  107),  and  also  from  the  Philippines  (station  205),  at  a  depth  of  1,050  fathoms. 

BASSOZETUS  TAENIA,  (Guntiier),  Goode  ami  Bean. 
Bathyonus tcenia,  GCntiier,  Challenger  Report,  xxn,  1*87,  110,  PI.  xxm,  Fig.  A. 

The  greatest  depth  of  the  body  is  below  the  origin  of  the  dorsal  tin  and  about  one-third 
of  the  length  of  the  trunk,  the  vent  being  not  quite  thrice  as  distant  from  the  extremity  of 
the  tail  as  from  the  snout.  Therefore  the  whole  fish,  and  especially  the  tail,  is  much 
attenuated.  Head  not  compressed,  low  and  long,  forming  four-sevenths  of  the  length  of 
the  trunk.  Structure  of  the  bones  of  the  head  as  in  Bassozetus  compressus.  Snout  rather 
swollen  and  broad,  the  upper  jaw  but  slightly  overlapping  the  lower.  Maxillary  extending 
far  behind  the  eye.  which  is  very  small,  one-third  the  length  of  the  snont.  about  one-four- 
teenth of  that  of  the  head,  and  one-fourth  of  the  width  of  the  interorbital  space.  All  the 
teeth  are  very  small  and  short,  densely  set,  forming  narrow  villiform  bands;  vomerine  band 
open,  V-shaped.  Gill-cavity  deep  black;  gill-rakers  long  and  slender,  sixteen  in  number, 
with  some  rudimentary  ones  in  front  and  behind. 

The  dorsal  fin  commences  above  the  upper  end  of  the  gill-opening,  with  short  rays 
partly  hidden  in  the  skin;  the  rays  become  longeron  the  anterior  third  of  the  tail,  but 
remain  of  moderate  length,  and  the  anal  rays  are  still  shorter.  The  pectoral  has  a  broad 
base,  is  quite  free,  and  composed  of  rather  feeble  rays;  its  length  is  equal  to  that  of  the 
postorbital  part  of  the  head.  Ventral  rays  very  feeble,  reaching  nearly  to  the  middle  of  the 
pectoral. 

The  scales  must  have  been  extremely  thin,  and  rather  small ;  there  an-  probably  about 
twenty  in  a  transverse  series  running  from  the  vent  to  the  dorsal  fin.  The  lateral  line  can 
not  be  made  out.

Body  very  elongate,  much  compressed,  and  tapering  into  a  slender,  whip  like  tail.  Its 
height  (19  millimeters)  is  contained  U  times  in  length  of  head  and  V2.\  times  in  that  of  the 
body. 

Head  without  spines,  very  cavernous,  not  much  compressed,  higher  than  body,  its 
length  (27  millimeters)  contained  S'^  times  in  that  of  body.  Interorbital  area  somewhat 
convex,  its  width  (measured  upon  the  bone)  equal  to  the  diameter  of  the  eye  and  about 
equal  to  that  of  the  snout,  and  contained  5  times  in  the  length  of  head. 


324  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

The  inuciferous  channel  upon  the  infraorbital  ring  shows  in  its  course  several  wide  sub- 
circnlar  sinuses,  closely  approximated;  a  similar  row  upon  the  posterior  edge  of  the  pre- 
operculum  and  continued  forward  upon  the  under  surface  of  the  mandible;  the  vertex  also 
has  a  semicircle  of  similar  sinuses.  To  the  chain  like  appearance  of  tliese  rows  of  ducts 
the  specific  name  has  reference.  (The  appearance  of  a  spine  over  the  eye,  as  shown  in  the 
drawing,  is  due  simply  to  the  shrinking  of  the  porous  adjacent  regions.) 

The  maxilla  extends  beyond  the  vertical  through  the  posterior  margin  of  orbit,  its 
length  equal  to  that  of  postorbital  part  of  head.  Mandible  two  thirds  as  long  as  head  and 
equal  in  length  to  height  of  body.  Jaws,  vomer,  and  palate  with  bands  of  villiform  teeth; 
the  vomerine  band  V-shaped. 

Nostrils  in  front  of  the  middle  of  the  eye,  separated  by  a  slight  interspace,  the  anterior 
nearer  to  its  mate  than  to  the  tip  of  the  snout. 

Brauehiostegals  8.     Pseudobranchia?  absent. 

Gill-rakers  long  and  numerous,  the  longest  slightly  exceeding  in  length  the  diameter  of 
eye;  15  developed  below  the  angle  of  the  first  arch,  besides  several  rudiments. 

The  dorsal  origin  is  slightly  behind  that  of  the  pectoral,  its  distance  from  the  tip  of 
the  snout  (32  millimeters)  about  7£  in  total;  rays  well  developed;  in  the  anterior  third  of 
the  fin,  in  a  space  equal  to  the  length  of  the  head,  were  counted  20  rays,  the  longesl  of 
which  is  two-fifths  as  long  as  the  head. 

The  anal  origin  is  under  the  twenty-first  dorsal  ray;  its  rays  are  shorter  than  those  of 
the  dorsal.  The  pectoral  extends  to  the  vertical  from  the  eighteenth  ray  of  the  dorsal.  It 
is  four-fifths  as  long  as  the  head. 

The  ventrals  are  composed  each  of  a  simple  filament,  the  origin  slightly  in  advance  of 
the  vertical  through  the  pectoral  origin,  the  length  two  thirds  that  of  the  head.  They  do 
not  reach  near  to  the  vent,  the  distance  of  which  from  the  origin  of  the  ventrals  (.'50  milli- 
meters) is  slightly  greater  than  the  length  of  the  head. 

Color,  brownish  yellow.     Head  and  abdomen  blackish.

In  genera]  form  resembling  Bythites  fuscus.  The  heighl  of  (lie  body  a  little  more  than 
one-fifth  of  its  length,  and  its  thickness  one-ninth;  the  length  of  the  head  isabouttwo 
elevenths  of  the  length  of  the  body;  it  is  thick,  with  an  in  Hated  snout.  Month  moderatelj 
wide,  the  maxillary  extending  slightly  beyond  the  vertical  from  the  posterior  limb  oJ  the 
orbit.  Fine  villiforni  teeth  on  tin'  two  jaws,  the  palatines  and  the  vomer,  and  a  lew-  teeth 
upon  the  tongue.  Eye  small,  its  diameter  about  one-eighth  the  length  of  the  head;  inter 
orbital  space  much  greater,  contained  about  two  and  three-fourths  times  in  the  length  of 
the  head.  Branchial  openings  very  wide.  Branchiostegal  membranes  free  from  the  isth- 
mus. Opercula  enveloped  in  thick  skin,  which  obscures  their  outlines.  Opercular  spine 
distinct,  strong,  flattened;  preoperculum  probably  obtusely  denticulated,  though  hidden 
in  the  integument.  Scales  small,  denticulate,  extending  upon  the  liases  of  the  vertical  fins 
and  even  of  those  of  the  pectorals,  about  156  <  .' )  in  longitudinal  series  and  7(1  in  vertical 
series.  A  lateral  line  parallel  with  the  back  about  one-third  of  the  distance  from  the 
dorsal  to  the  ventral  outline,  indistinct  posteriorly. 

Origin  of  dorsal  behind  base  of  pectorals:  the  fin  is  low,  its  height  hardly  one-third 
that  of  the  body,  its  base  buried  in  the  skin.  The  anal  is  similar  to  the  dorsal,  and  begins 
immediately  behind  the  vent.  The  caudal  is  confluent  with  the  vertical  fins.  Pectoral 
short,  about  half  as  long  as  the  head:  rounded.  Yentrals  each  of  two  rays,  closely  united 
at  their  base;  the  length  of  the  inner  one  exceeds  half  the  height  of  the  body,  the  outer  one 
three  tilths  of  the  same. 

Color,  reddish-brown,  deeper  upon  the  fins.     (  Vaillant.) 

A  single  specimen  was  obtained  by  the  French  expedition  at  station  cxxxvi,  at  a 
depth  of  4,255  meters. 

BENTHOCOMETES,  Goode  and  Bean,  n.  g. 

Brotulids,  similar  in  appearance  and  structure  to  Neobythites  and  Bassogigas,  distin- 
guished by  two  short,  Hat  spines  upon  the  anterior  portion  of  the  operculum,  placed  at 
some  distance  from  each  other,  and  by  the  absence  of  spines  upon  the  preoperculum.  The 
lateral  line  is  complete,  and  extends  without  interruption  to  the  posterior  fourth  of  the 
body,  where  it  becomes  obsolete.  The  vomerine  teeth  are  bunched  in  a  circular  patch 
instead  of  being  arranged  in  triangular  form.  The  head  is  comparatively  short,  with  the 
jaws  in  front  nearly  equal;  the  snout  not  produced,  but  obtuse,  rounded,  and  almost 
declivous  in  its  outline. 

Two  species  have  been  assigned  to  this  genus — Neobythites  robustus,  Goode  and  Bean, 
and  Sirembo  murcenolepis,  Vaillant.  The  latter  is  not,  as  Vaillant  supposed,  related  to 
Dvplacanthopoma,  which,  though  it  has  two  spines  upon  the  preoperculum,  and  is  very  sim- 
ilar in  general  appearand',  has  the.  ventrals  single  rather  than  double. 

BENTHOCOMETES  ROUCSTITS,  (U ::u.<1Bean.     (Figure  288.) 

Neobythites  robustus,  Goode  and  Dean,  Bull.  Mua.  Comp.  Zool.,  mi.  161. 

Body  rather  short  and  deep,  its  greatest  height  (16  millimeters)  nearly  4'r|  in  total  length 
and  about  ecpial  to  length  of  head.  The  interorbitaJ  area  is  convex;  its  width  (6  milli- 
meters) is  greater  than  the  diameter  of  the  circular  eye  (5  millimeters)  and  14  times  the 
Length  of  snout  (4  millimeters).  The  length  of  the  head  (19  millimeters)  is  about  4  times 
the  diameter  of  the  eye.  The  mouth  is  moderate,  the  maxilla  extending  to  the  vertical 
through  the  posterior  margin  of  the  eye,  the  mandible  a  little  beyond,  its  length  (10  mil- 
limeters) equal  to  that  of  postorbital  part  of  head.  Teeth  in  villiform  bands  in  the  jaws 
and  on  the  palatines.  Vomerine  teeth  bunched  in  a  circular  patch.  (Jill  rakers  moderate, 
the  longest  a  little  more  than  twice  in  diameter  of  eye,  1  above  angle  of  first  arch.  1 1  below. 
Pseudobranchia'  rudimentary.  Gill-opening  wide,  the  membrane  deeply  cleft,  behind  free 
from  the  isthmus.     A  pair  of  short  flat  spines  upon  the  anterior  portion  of  the  operculum. 


328  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

The  nostrils  ire  small,  the  anterior  as  close  to  the  snout  as  the  posterior  ones  are  to 
the  eyes.  No  apparent  cirri.  The  scales  are  minute;  the  lateral  line  is  obsolete  on  the  last 
fourth  of  the  length  of  the  body. 

The  dorsal  origin  is  behind  that  of  the  ventral  and  pectoral;  its  distance  from  the 
snout  (24  millimeters)  is  contained  3{}  times  in  length  of  the  body.  The  height  of  the 
fin  is  moderate;  the  longest  ray  is  contained  about  3  times  in  the  length  of  the  head. 

The  anal  origin  is  under  the  eighteenth  ray  of  the  dorsal;  rlie  height  of  the  tin  about 
equals  that  of  the  dorsal.  The  vertical  fins  arc  not  connate  with  the  caudal,  which  consists 
nf  12  or  13  very  slender  rays,  its  length  nearly  equal  to  half  that  of  head. 

The  pectoral  with  a  broad  base,  close  to  gill-opening,  its  length  nearly  two-thirds  that 
of  the  head. 

The  ventral  a  single  bifid  ray,  inserted  in  advance  of  the  vertical  through  the  base  of 
'In-  pectorals,  and  not  far  from  the  humeral  symphysis.  It  reaches  nearly  half-way  to  the 
vent,  the  distance  of  which  from  the  origin  of  the  ventral  is  equal  to  the  length  of  the  head.1 

Color,  yellowish  brown. 

The  type  of  this  species,  a  specimen  88  millimeters  in  length,  was  taken  by  the  Blake 
from  station  xciv,  off  Moro  Castle,  Cuba,  at  a  depth  of  from  250  to  400  fathoms.  A  col- 
lateral type  specimen  (Cat.  No.  29057,  O.  S.  N.  M.)  was  obtained  by  the  Fish  Haiti;  from 
station  1043,  in  38°  39'  N.  hit..  7!:  11'  VY.  Ion.,  at  a  depth  of  130  fathoms.

This  species  does  not  appear  to  be  very  unlike  the  preceding,  but  without  examination 
of  the  type  we  hesitate  to  pronounce  it  identical. 

Two  specimens  were  obtained  by  the  French  explorers  at  station  lxix,  oil'  the  coast  of 
Soudan,  in  410  meters. 

BASSOGIGAS.  Gill. 
Bassogigas,  GlLL,  Ms. 

Brotulids  having  the  body  elongate,  compressed,  covered  with  a  thick,  heavy  skin, 
which  upon  the  head  covers  anil  obscures  all  the  angles  of  the  skull.  Scales  small,  cover- 
ing body  and  head  completely.  Lateral  line  indistinct  for  tliegrcater  part  of  its  course, but 
apparently  extending  at  least  two-thirds  of  the  way  from  the  operculum  to  the  tail.  Eye 
moderate.  Vertical  tins  completely  united;  ventralsa  pair  of  bifid  filaments  inserted  behind 
the  humeral  symphysis,  and  remote  at  their  bases,  short,  rather  stout.  Snout  without 
barbels,  slightly  produced,  the  lower  jaw  being  barely  included.  Villiform  teeth  in  the 
jaws,  on  the  vomer  and  palatines;  vomerine  patch  V-shaped,  but  with  its  arms  broadly 
expanded  and  thicker  at  the  angle,  so  that  it  is  almost  triangular.  Operculum  with  a  long, 
sharp  spine;  preoperculum unarmed.  Branchiostegals  eight.  Air-bladder  present.  Pseu- 
dobranchiae  small. 

B.pterotm  (Alcock)  =  Neobythites  pterotus  (Alcock,  Ann.  and  Mag.  Xat.  Hist.,  1889,11, 
210)  is  characterized  by  long  feathery  peduncles  reaching  beyond  the  vent.  One  specimen 
was  taken  by  the  Investigator  at  station  07,  in  the  Bay  of  Bengal,  at  a  depth  of  1,310  fathoms. 

Neobythites  stelliferoides,  Gilbert,  obtained  by  the  Albatross  in  712  fathoms  off  the  west 
coast  of  Lower  California,  is  perhaps  not  remotely  related  to  this  genus. 

BASSOGIGAS  GILLII,  Goode  and  Bean,  n.  s.     (Figure  291.) 

Head  rather  short  and  broad,  with  snout  slightly  overlapping  the  lower  jaw.  Diameter 
of  the  eye  scarcely  one-third  of  the  length  of  the  snout,  and  about  one-twelfth  of  that  of  the 
head;  the  maxillary  extending  far  behind  the  eye,  the  vertical  from  the  anterior  margin 
of  the  orbit  nearly  bisecting  it;  its  length  half  that  of  the  head,  and  its  posterior  margin 
ending  in  a  broad,  triangular  dilation.     Teeth  normal.     Anterior  and  posterior  nostrils

separated  by  a  space  greater  than  the  diameter  of  the  eye.     Preoperculum  with  a  square, 
rounded  angle;  no  armature;  operculum  with  ;i  si  num.  sharp  spine  above,  the  tip  of  which 
projects  slightly  beyond  the  opercular  flap.     Distance  of  the  vent  from  the  root  of  the  pec 
toral  slightly  more  than  the  length  of  the  bead;  as  far  removed  from  this  point  as  is  the 
anterior  nostril. 

Scales  moderate,  covering  the  entire  head.  Lateral  line  somewhat  conspicuous,  obso- 
lete in  its  posterior  third. 

The  dorsal  and  anal  litis  enveloped  in  thick,  scaly  skin.  The  origin  of  the  dorsal  is  in 
advance  of  the  middle  of  the  pectoral.  Pectorals  rounded,  broad,  and  very  short ;  less  than 
half  as  long  as  the  head,  and  extending  about  half  the  distance  from  their  origin  to  the  ver 
tieal  from  the  vent.  Yentrals  inserted  somewhat  behind  the  angle  of  the  preoperculum, 
and  extending  to  the  vertical  from  the  axil  of  the  pectoral,  and  about  one-fourth  of  the  dis 
tance  from  their  origins  to  the  vent;  each  ventral  lilauieut  is  bilid,  the  inner  part  being 
the  longer. 

Radial  formula:   Vertical  tins,  83+6+G7. 

Color,  uniform  grayish-brown;  tins  darker. 

The  type  was  obtained  by  the  Albatross  from  station  2684,  off  Cape  ITenlopen,  Dela- 
ware, in  39°  .'!•">'  X.  hit.,  70°  54'  W.  Ion.,  at  a  depth  of  1,106  fathoms. 

This  form  resembles  so  closely  the  figure,  of  Weobythites  grandis,  Gunther,  (('hall.  Rep. 
xxii,  1(10,  pi.  xxi,  fig.  A),  that  the  species  was  provisionally  identified  as  the  same,  but  a 
more  careful  study  shows  that  it  differs  in  certain  particulars,  especially  in  the  more  distinct 
lateral  line,  the  rather  shorter  body,  and  the  fact  that  the  vent  is  considerably  farther  back 
(more  than  twice  the  length  of  the  pectoral  from  the  gill  opening),  while  the  ventrals  do  not 
reach  more  than  one-fourth  of  the  way  to  the  vent.  The  rays  in  the  vertical  fins  will  prob- 
ably be  found  to  be  fewer,  though  Gunther  has  not  enumerated  those  in  his  type. 

ALCOCKIA,  Goode  and  Bean,  n.  g. 

Brotulids  resembling  Neobythites  in  the  general  form  of  the  body,  with  no  continuous 
lateral  line,  though  traces  can  be  distinguished  at  various  parts  of  the  body,  and  with  a 
head  and  snout  similar  in  appearance  to  those  of  Bassozetus,  though  the  former  is  peculiarly 
shaped.  Bones  of  the  head  rather  thin,  with  large,  somewhat  conspicuous  sinuses.  Sharp, 
well-developed  spines  upon  the  operculum  and  preoperculum  (which  has  a  crenulated 
margin),  behind  the  eye,  upon  the  superciliary  crest,  and  behind  the  posterior  nostril, 
which  is  separated  from  the  orbit  by  a  short,  spinous  projection,  as  in  Bathybrotula.  Mn 
eiferous  channels  ample,  that  of  the  frontal  bone  opening  in  front  by  a  wide  aperture  on 
each  side  of  the  rostral  projection,  and  each  mandibulary  canal  opening  in  front  immedi- 
ately behind  the  symphysis  by  a  slit  in  the  skin.  The  mucous  membrane  of  the  nasal  cavity 
in  two  folds,  forming  together  a  longitudinal  pad  with  a  linear  base.  Teeth  in  villiform 
bands  on  jaws,  vomer,  and  palatines;  the  vomerines  open  V-shaped  and  much  narrower 
than  the  palatine  band.  Pectorals  narrow  and  feeble.  Ventrals  each  composed  of  two 
filaments,  short,  very  feeble  and  close  together,  inserted  on  isthmus,  some  distance  from 
symphysis.  Scales  cycloid,  persistent,  irregular.  Gill-lamina'  short:  gill  rakers  stiff,  far 
apart,  and  but  few  in  number.  Branchiostegals  8.  Pseudobranchia'  represented  by  two  or 
three  small  lobes. 

This  genus  is  provisionally  proposed  for  the  Porogadus  rostral  us  of  Gunther  (Challenger 
Report,  xxii.  1887,  lb">,  pi.  xxiv.  fig.  B)  obtained  by  the  Challenger  from  station  198,  north 

Of  Celebes,  at  a  depth  of  2,150  fathoms. 

The  genus  is  named  in  honor  of  A.  Alcock,  M.  !'>..  surgeon-naturalist  to  the  II.  M.

our  knowledge  of  the  bathybial  fauna  of  the  Indian  Ocean. 

CELEMA,  Goode  and  Bean,  n.  g. 

Brotulids  closely  resembling  in  appearance  Mcebia,  though  with  the  rays  of  the 
vertical  tins  apparently  less  abbreviated  on  the  posterior  part  of  the  caudal  Unlet,  and 
without  the   short   row  of  specialized   large   scales   beginning  above  the  angle  of  the  gill-

opening.  Head  very  cavernous,  with  the  sinuses  very  conspicuous  in  preserved  specimens, 
and  with  numerous,  rather  strong  spines  upon  the  upper  part  of  the  opercular  apparatus 
and  the  head.  Teeth  on  jaws,  vomer,  and  palatines.  No  traces  of  scales  upon  the  head. 
Character  of  lateral  line  unknown.  Dorsal  beginning  somewhat  behind  the  vertical  from 
the  axil  of  the  pectoral.  Anal  close  to  the  vent;  its  distance  from  the  base  of  the  pectoral 
is  about  equal  to  the  length  of  the  head.  Pectorals  broad,  very  feeble.  Ventrals  feeble 
and  short,  each  composed  of  two  rays,  the  inner  one  the  more  abbreviated. 

This  genus  is  provisionally  proposed  for  the  reception  of  the  two  species  referred  by 
Vaillant  to  our  Porogadus,  to  which  they  evidently  do  not  belong,  being  separated  not  only 
by  the  structure  of  the  head  and  the  shape  of  the  body,  but  by  the  absence  of  the  triple 
row  of  pores,  which  replace  the  lateral  line  in  that  genus  and  Penopus.  The  characters 
presented  are  gleaned  from  the  descriptions  of  Vaillant,  and  are.  in  the  absence  of  specimens, 
offered  only  as  tentative. 

CELEMA  NUDA,  (Vaillant),  Goode  and  Bean. 

Porogadus  nudus,  Vaillant,  Exp.  Sci.  Travailleur  et  Talisman,  262,  pi.  xxiv,  figs.  2-2b. 

Body  much  elongated,  its  height  one-twelfth,  and  its  thickness  one-fifteenth  of  its 
length.  Length  of  head  one-seventh  of  that  of  body;  in  the  specimen  as  preserved  in  spirits 
it  is  rough,  bristly  with  spines,  and  has  a  median  crest  (the  position  of  these  is  described 
at  length  by  Vaillant,  but  is  sufficiently  well  indicated  in  the  figure).  Snout  round,  liat, 
its  length  two-sevenths  that  of  the  head.  The  mouth  large,  the  maxillary  passing  con- 
siderably behind  the  eye.  Teeth  very  line,  in  villiform  bands  upon  the  jaws,  vomer,  and 
palatines.  Eye  conspicuous,  its  diameter  one-fifth  the  length  of  the  head  and  equal  to  the 
width  of  the  interorbital  space.  Suborbital  distinct,  rough.  Branchial  opening  very  wide. 
Preoperculum  with  a  double. margin,  each  portion  of  which  has  three  obtuse  spines;  oper- 
culum with  a  single  spine.  No  scales  upon  the  head,  the  mucous  sinuses  being  very  much 
developed,  particularly  in  the  suborbitals  and  on  the  margin  of  the  preoperculum  Caudal 
peduncle  large,  attenuated,  nearly  filiform  posteriorly.  Vent  a  little  in  front  of  the  limit 
of  the  anterior  third  of  the  body,  and  at  a  distance  from  the  origin  of  the  ventrals  greater 
than  the  length  of  the  head.  Dorsal  origin  a  little  behind  the  base  of  the  pectorals.  Anal 
origin  immediately  behind  the  vent.  These  fins  are  moderately  high,  and  confluent  with 
the  caudal,  which  is  not  very  long.  Pectorals  moderate,  their  length  a  little  more  than 
two-thirds  that  of  the  head.  Ventrals  a  little  longer  than  the  pectorals,  the  inner  ray 
slightly  shorter  than  the  outer  one.  Scales  almost  entirely  absent,  a  few  visible  in  the 
vicinity  of  the  branchial  opening.     No  trace  of  lateral  line  distinguishable. 

Color  rosy-white,  with  the  lower  parts  of  the  body,  sides  of  head,  and  the  opercular 
region  bluish-black. 

Three  specimens  were  obtained  by  the  French  expedition  at  station  xcvui,  on  the 
Banc  d'Arguin,  at  a  depth  of  13,321  meters,  and  at  station  ci,  off  the  Cape  Verde  Islands,  at

Porogadus  suoarmatus,  Vaillant,  Exp.  Scient.  Travailleur  et  Talisman,  Poissons,  LT>r>,  p],  xxiv.  figs.  3-3r. 

A  species  closely  allied  to  C.  nuda.  but  with  a  shorter  head,  its  length  only  one-eighth 
that  of  the  body.  Interorbital  space  wider,  its  width  being  two  ninths  of  the  length  of  the 
head,  and  a  little  more  than  the  diameter  of  the  eye,  which  is  contained  in  the  length  of  the 
head  only  5J  times.  The  head  is  less  spinous.  The  space  between  the  ventrals  and  the 
vent  a  little  greater  than  the  length  of  the  head.  Scales  very  deciduous,  and  lacking  on 
almost  all  the  specimens  studied.  Vaillant  describes  the  form  of  one  which  he  found  near 
the  opercular  opening,  evidently  an  intracutaneous  cycloid  scale. 

Color  like  that  of  ('.  nuda,  the  opercular  flap  and  the  abdomen  presenting  a  blackish 
tint  on  account  of  their  transparency,  the  mucous  membranes  within  being  exceedingly 
dark. 


DISCUSSION    OF    SPECIES    AND    THEIK    DISTRIBUTION.  331 

Eleven  specimens  were  taken  by  the  French  expedition  at  station  n,  off  the  Cape 
Verde  [stands,  at  a  depth  of  3,200  meters.  They  wore  evidently  spawning,  for  red  eggs  were 
protruding  from  the  abdomen. 

MCEBIA,  Goode  and  Bean,  n.  g. 

Brotulids  resembling  Bassozetus  in  general  form,  excepting  that  the  tail  is  prolonged  in 
averyslender  filament,  the  dorsal  and  anal  rays  being  extremely  short  posteriorly,  hut 
positively  confluent  with  the  caudal  rays,  which  are  much  longer  and  much  oxserted.  Ven 
rals  each  bifid,  instead  of  a  single  ray  as  in  Bassozetus.  He  id  very  cavernous,  the  sinuses 
large  and  conspicuous  on  the  infraorbital  ring,  on  the  mandible,  and  the  preoperculum.  A 
single,  short,  feeble  spine  on  the  shoulder,  but  none  upon  the  operculum  or  preoperculum, 
though  certain  projections  seem  to  show  above  the  eye,  doubtless  due  to  the  shrinkage  of 
the  integument  upon  the  underlying  projections  of  bone.  Mouth  very  wide,  the  extremity 
of  the  maxillary  much  dilated.  Posterior  nostrils  very  wide,  and  separated  from  the  eye 
b\  a  small,  spinous  projection  of  bone.  Teeth  in  narrow  bands,  that  on  the  vomer  V-shaped 
with  the  two  arms  straight.  A  few  very  large  scales  in  a  row  starting  from  the  upper 
angle  of  the  gill-opening  and  terminating  over  the  axil  of  the  pectoral.  Gill-rakers  on 
outer  arch  rather  numerous,  long  and  slender.  Pseudobranchife  represented  by  t  wo  minute 
globules. 

This  genus  is  founded  upon  Bathynectes  gracilis  of  Giinther  (Ann.  and  Mag.  Nat.  Hist. 
1878,  ii,  21;  Challenger  Report,  xxu,  112,  pi.  xvi,  tig.  B),  provisionally  referred  by  G-iinther 
to  our  genus  Porogadus. 

It  is  named  in  honor  of  Prof.  Karl  Moebius,  Director  of  the  Royal  Zoological  Museum  in

der  Kielerbucht,  and  by  numerous  other  writings. 

It  is  but  right  to  say  that  at  the  time  its  reference  was  made,  no  figure  of  Porogadus 
had  been  published,  and  some  of  the  most  salient  characters,  which  we  tried  to  bring  out 
prominently  in  our  generic  diagnosis,  seem  not  to  have  been  sufficiently  emphasized,  so 
that  both  Dr.  Giinther  and  Dr.  Vaillant  were  misled  as  to  the  real  affinities  of  our  species 
Porogadus  miles,  the  type  of  the  genus. 

Mn  hiit  gracilis  was  obtained  by  the  Challenger  af  station  184,  south  of  New  Guinea, 
at  a  depth  of  1,400  fathoms.

Amer.,  1885,  127.— GOnther,  Challenger  Report,  xxn,  1887,  09. 

Body  much  compressed.  Dorsal  arid  anal  outline  approaching  at  an  equal  angle  the 
horizontal  axis.  The  height  of  the  body  is  contained  7i  times  in  its  total  length  without 
caudal,  and  8J  times  with  caudal  included.  Scales  small;  about  175  rows  between  the 
branchial  opening  and  the  tail;  and  about  34  rows,  counting  upward  and  forward  obliquely 
from  the  origin  of  the  anal  to  the  dorsal  line.     Lateral  line  apparently  absent. 

Head  considerably  compressed,  with  rounded  upper  surface,  its  length  contained  about 
six  times  in  total  body  length;  its  width  contained  2  J  times  in  its  length;  its  greatest 
height  equals  two  thirds  its  length.  Snout  slightly  longer  than  the  horizontal  diameter  of 
the  eye,  and  projecting  beyond  the  tip  of  the  upper  jaw  a  distance  equal  to  the  vertical 
diameter  of  the  eye;  much  dilated  and  swollen,  the  anterior  pair  of  nostrils  being  situated 
at  the  most  salient  angles;  the  snout  in  general  form  resembling  that  of  a  manatee,  whence 
the  specific  name. 

Mouth  moderate ;  its  cleft  extending  to  the  vertical  from  the  center  of  the  orbit.  Length 
of  the  the  upper  jaw  equal  to  twice  the  horizontal  diameter  of  the  eye,  and  contained  2A 
times  in  the  length  of  the  head.  The  posterior  portion  of  the  maxilla  is  considerably  ex- 
panded. The  maxilla  is  largely  included  within  a  skinny  sheath.  When  the  mouth  is 
closed,  the  lower  jaw  is  entirely  included  within  the  upper.  Vomer  and  palatine  with 
bands  of  teeth  more  than  twice  as  broad  as  the  bands  in  the  intermaxillaries  and  on  the 
mandible. 

Eye  elliptical  in  form.  Its  vertical  diameter  two-thirds  of  its  horizontal,  the  latter  being 
equal  to  the  distance  from  the  tip  of  the  snout  to  the  posterior  nostril,  and  contained  5] 
times  in  the  length  of  the  head.  The  distance  of  the  eye  from  the  dorsal  outline  is  equal 
to  half  its  horizontal  diameter,  and  to  one-fifth  of  the  height  of  the  head  in  a  perpendicular 
through  the  center  of  the  eye.  Interorbital  space  rounded;  its  width  equal  to  the  horizon- 
tal diameter  of  the  eye. 

Dorsal  fin  inserted  in  the  vertical  above  the  insertion  of  the  pectoral,  at  a  distance 
from  the  end  of  the  snout  equal  to  that  of  the  insertion  of  the  pectoral. 

Anal  inserted  under  the  twenty-first  to  tweuty-third  dorsal  ray,  and  at  a  distance  from 
the  snout  about  equal  to  one-third  the  body  length.  The  height  of  the  dorsal  and  anal  tins 
is  about  equal  to  half  the  height  of  the  body  at  the  insertion  of  the  anal.  Their  bases  ex- 
tend almost  to  the  insertion  of  the  caudal. 

The  caudal  is  composed  of  9  rays,  the  5  medial  ones  almost  equal  in  length,  though  the 
tip  of  the  tail  is  slightly  rounded,  about  equal  to  the  height  of  the  body  midway  between 
the  branchial  opening  and  the  base  of  the  tail. 

The  ventrals  are  inserted  almost  under  the  middle  of  the  operculum;  in  length  about 
equal  to  half  the  length  of  the  head. 

The  pectorals  are  inserted  under  the  origin  of  the  dorsal,  and  at  a  distance  behind  the 
branchial  opening  equal  to  two  thirds  the  vertical  diameter  of  the  eye.  The  length  is  equal 
to  the  greatest  height  of  the  body. 

Radial  formula:     D.  106;  A.  86;  C.  2  +  5+2;  P.  18-20;  V.  \. 

Scales  in  lateral  line  about  175.

NEMATONUS,   Gunther. 

Nematonus,  Gunther,  Challenger  Report,  xxn,  1887,  114  (type,  Bathyonus pectoralis,  Goode  and  Bean). 

Body  compressed,  with  long,  tapering  tail.  Bones  of  head  soft,  muciferous  channels 
moderately  developed,  and  with  integument  very  thin  or  absent  on  the  upper  portion  and 
snout.  Operculum  cartilaginous  and  Hat;  a  broad  process  near  its  upper  angle  correspond- 
ing to  the  opercular  spine  in  some  of  the  related  genera;  the  head  otherwise  unarmed, 
though  irregular  by  reason  of  the  bareness  of  the  cranial  bones.  Snout  much  depressed, 
broad,  rounded.  Jaws  equal  in  front;  mouth  very  wide;  bands  of  villiform  teeth  in  jaws, 
on  vomer  and  palatines.  Barbel  none.  Eyes  small.  Vertical  tins  continent:  ventrals  a 
pair  of  bifid  filaments  close  together,  on  the  isthmus,  close  to  the  humeral  symphysis.  Gills 
lour,  with  very  short  laminae  and  rather  short,  incurved,  acicular  gill-rakers  on  the  first 
arch,  and  much  shorter,  less  numerous,  spatulate  ones  upon  the  three  other  arches.  Pseu 
dobranchise  rudimentary.  No  traces  of  a  lateral  line,  though  the  bodyis  covered  with  scales 
of  considerable  size,  almost  as  large  as  the  eye,  and  the  cheek  with  others  still  larger. 

Nematonm  differs  from  Porogadm  not  only  in  the  absence  of  spines  upon  the  head,  as 
Gunther  has  indicated,  but  in  the  much  less  ossified  opercular  apparatus,  in  the  shorter  and 
thicker  head,  in  the  absence  of  the  three  series  of  pores  simulating  lateral  lines,  and  in  the 
tendency  to  prolongation  in  the  lower  rays  of  the  pectoral,  which  increase  from  the  upper 
most  to  the  lowermost  in  Nematonus,  while  Porogadus  has  a  lanceolate  fiu,  and  also  in  the 
extreme  exsertion  of  its  caudal  rays.

panded  at  its  tip;  its  length  (13  millimeters)  more  than  halt  that  of  head.    Length  of  man 
dible  (15  millimeters)  equal  to  greatest  height  of  body,    .laws,  vomer,  and  palatines  with 
narrow  bands  of  villiform  teeth,  none  of  which  are  enlarged.    Gill  rakers,  15  on  anterior 
arch  below  tin'  angle,  ■'<  rudimentary  ones  above. 

The  anterior  pair  of  nostrils  are  nearly  on  top  of  the  snout,  and  somewhat  nearer  to 
its  tip  than  to  the  eye,  separated  by  a  very  narrow  space,  and  placed  immediately  in  front 
of  the  middle  of  the  eye.    Behind  each  posterior  nostril  is  a  strong  spine  projecting  out 
ward  and  backward.     Tores  of  the  head  arranged  much  as  in  Bassozetus. 

Scales  minute.  Lateral  line  not  clearly  to  be  made  out.  Three  rows  of  minute  pores 
on  each  side  dorsal,  median,  and  ventral,  beginning  near  the  head  and  extending  well  to- 
ward the  extremity  of  the  tail. 

Dorsal  origin  slightly  behind  vertical  through  pectoral  base;  its  distance  from  the 
snout  (25  millimeters)  marly  <>  times  in  length  of  body.  -Its  rays  are  moderately  long,  the 
longest  about  as  long  as  the  snout  (one-fourth  of  head),  and  very  numerous.

Color,  blackish  brown. 

The  type  (No.  35625,  U.S.N.  M.)  is  153  millimeters  in  length;  it  is  from  Albatross 
station  2230,  N.  lat.  38°  27',  \V.  Ion.  73°  02',  at  a  depth  of  1,168  fathoms. 

PENOPUS,  Goode  and  Bean,  n.  g. 

Body  stout  in  front,  tapering  behind.  Tail  not  greatly  exceeding  the  length  of  the 
rest  of  the  fish.  Head  scaly,  thick,  its  top  surface  flat,  with  depressed  and  moderately 
projecting  snout.  A  pair  of  minute  postnasal  spines;  a  strong  and  much  curved  spine  on 
the  operculum ;  several  weak  spines  at  the  angle  of  the  preoperculum,  and  several  at  the 
posterior  angle  of  the  suboperculum.     Mouth  moderately  large,  the  lower  jaw  included. 

Several  narrow  slit-like  pores  along  the  margin  of  the  preorbital  and  suborbital. 
Two  minute  pores  on  the  under  surface  of  the  mandible  near  its  symphysis,  and  not  far 
behind  them  two  long  slit-like  pores. 

The  anterior  nostril  is  in  a  long  slit,  the  posterior  is  larger,  oblong  in  shape,  and  half 
concealed  by  a  fold  of  skin.  Eye  small.  The  teeth  appear  only  as  minute  asperities;  the 
intermaxillary  band  much  wider  in  front  than  behind.  Mandibulary  band  narrow  through- 
out. Vomerine  band  very  narrow  V-shaped.  Palatines  in  a  long  broad  band.  Gill-open 
ings  wide,  deeply  cleft  in  front,  narrowly  joined  to  the  isthmus.  Branchiostegals  8.  No 
pseudobrancbise.  The  gill-rakers  are  long  and  slender;  not  numerous.  Gill-lamina'  moder 
ately  loug.  A  long  slit  behind  the  fourth  gill.  Scales  very  small.  Lateral  lines,  three. 
Caudal  tin  consisting  of  few  rays,  well  differentiated  from  the  dorsal  and  anal.  Dorsal 
beginning  not  far  behind  the  head.  Ventrals  slightly  in  advauce  of  the  pectorals  and 
composed  of  two  rays,  united  by  membrane,  which  forms  a  margin  around  them. 

Pectoral  normal;  several  of  its  upper  rays  simple.  The  vent  is  not  much  in  advance 
of  the  middle  of  the  total  length. 

This  genus  agrees  with  Porogadus  in  nearly  every  respect  except  in  the  scarcity  of  spines 
on  the  head  and  in  the  structure  of  the  ventrals.  Porogadus  has  the  ventrals  composed  of 
two  distinct  rays  which  are  separated  throughout  their  entire  length,  but  in  Penopus  the 
two  rays  are  inclosed  in  a  membrane  which  connects  them  and  forms  a  margin  around 
them.  In  Porogadus,  also,  the  suboperculum  has  a  smooth  margin  and  the  opercular  spine 
is  weaker  than  in  Pmopus,  and  it  is  not  curved.

PENOPUS  MACDONALDI,  Goode  AND  Bean,  n.  s.     (Figure  293.) 

The  greatest  height  of  the  body  (35  millimeters)  equals  the  length  of  the  postorbital 
part  of  the  head  arid  about  one-ninth  of  the  total  without  the  caudal.  The  greatest  width 
of  the  body  anteriorly  is  about  two-thirds  of  its  greatest  height.  The  head  is  stout,  its 
greatest  width  equaling  three-fourths  of  its  greatest  depth  and  more  than  one  third  of 
its  length.  The  width  of  the  interorbital  space  (14  millimeters)  is  about  one-fifth  the  length 
of  the  head.  The  eye  is  very  small,  its  length  (0  millimeters)  less  than  one-half  the  width 
of  the  interorbital  space.  The  distance  from  the  eye  to  the  tip  of  the  snout  (24 millimeters) 
equals  the  length  of  the  iutermaxilla.  The  distance  of  the  anterior  nostril  from  the  tip  of 
the  snout  equals  the  length  of  the  eye.  The  distance  of  the  posterior  nostril  from  the  eye 
is  slightly  less  than  its  distance  from  the  tip  of  the  snout.  The  maxilla  is  expanded  behind 
and  reaches  somewhat  behind  the  eye;  its  length  (25  millimeters)  equals  the  length  of  the 
snout.  The  mandible  extends  much  behind  the  eye,  its  length  (36  millimeters)  equal  to 
postorbital  part  of  head.  The  dorsal  begins  over  the  middle  of  the  pectoral;  its  rays  are 
well  developed,  those  in  the  middle  of  the  fin  longer  than  the  anterior  ones.  It  contains 
137  rays.  The  anal  begins  under  the  twenty-seventh  ray  of  the  dorsal;  it  contains  102 
rays,  those  about  the  middle  of  the  fin  longest.  The  length  of  the  pectoral  (32  millime- 
ters) is  nearly  one-half  the  length  of  the  head  and  about  equal  to  the  distance  of  its  tip 
from  the  vent.  The  length  of  the  ventral  (27  millimeters)  is  about  one-third  of  the  distance 
of  its  origin  from  the  origin  of  the  anal. 

Lateral  lines,  three;  the  uppermost  beginning  at  the  upper  angle  of  the  gill  opening 
quicky  approaching  the  top  of  the  body  near  the  base  of  the  dorsal  and  merging  into  the 
dorsal  base  about  the  middle  of  the  tail;  the  median  lateral  line  begins  a  little  behind  the 
head  and  extends  almost  to  the  root  of  the  caudal,  becoming  very  faint  posteriorly.  The 
lowermost  lateral  line  has  its  origin  under  and  not  far  from  the  base  of  the  pectoral.  It 
extends  along  the  lower  side  of  the  tail  and  merges  into  the  base  of  the  anal  fin  somewhat 
beyond  the  middle  of  the  length  of  the  tail. 

Color,  yellowish  brown;  operculum,  opercular  flap  and  branchiostegal  membrane,  pec- 
toral, and  ventral  dusky. 

The  siugle  specimen  obtained  is  315  millimeters  long,  catalogue  number  39433.  It  was 
obtained  by  the  steamer  Albatross,  September  is.  1886,  at  station  271G,  N.  lat.  38°  29'  30",

Brotulids  with  body  moderately  compressed;  head  somewhat  compressed,  with  mouth 
large  (in  the  type  species  extending  nearly  to  the  posterior  margin  of  the  eye).  The  tip  of 
the  maxillary  much  dilated.  Eye  large,  placed  close  to  the  dorsal  profile.  Head  with  supra- 
orbital spines;  several  strong  spines  on  the  preoperculum,  and  one  long  spine  at  the  upper 
angle  of  the  operculum.  Snout  short,  not  projecting  beyond  the  upper  jaw.  Jaws  nearly 
equal  in  front.  Teeth  in  narrow  villiform  bands  in  the  jaws,  on  the  head  of  the  vomer,  and

338  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

Alcock  states  that  in  young  individuals  the  lower  (free)  rays  are  very  much  less  clearly 
separated  from  the  rest  of  the  flu  and  from  each  other  than  in  the  adults.  (Aim.  and  Mag. 
Nat.  Hist.,  1872,  348.) 

Another  species,  D.  nigricaudis,  was  obtained  from  the  Andaman  Sea,  Investigator 
station  115,  in  188  and  120  fathoms.     (Ann.  and  Mag.  Nat.  Hist.,  1891,  July  31.) 

Alcock  has  also  identified  a  third  species,  taken  in  the  Laccadive  Sea,  with  the  form 
described  and  figured  by  Vaillant  as  Dicrolene  intronigra,  Goode  and  Beau,  proposing  for 
it  the  name  Paradicrolene  Vaillantii.  (Ann.  and  Mag.  Nat.  Hist.,  1890  (Oct.),  297).  We  are 
of  the  opinion  that  Vaillant's  fish  and  ours  are  conspecitic. 

The  erroneous  printing  of  "  P  for  "8"  in  our  description  of  the  branchiostegals  of 
D icrolene  has  •unfortunately  misled  Mr.  Alcock.

Body  moderately  compressed,  its  dorsal  and  aual  outlines  approaching  at  an  equal  angle 
the  horizontal  axis,  and  tapering  to  a  narrow  point,  which  forms  the  base  of  the  caudal  fin. 
Scales  small,  about  110  rows  between  the  branchial  opening  and  the  tail,  and  about  27  trans- 
verse rows  counting  upward  and  forward  obliquely  from  the  origin  of  the  anal.  The  lateral 
line  rudimentary,  running  near  the  base  of  the  dorsal  tin  at  a  distance  from  it  less  than  the 
diameter  of  the  eye,  and  apparently  becoming  obsolete  on  the  posterior  third  of  the  body. 
Body  height  one-sixth  of  standard  length. 

Head  somewhat  compressed,  with  ilattish  upper  surface,  which  is  encroached  upon  by 
the  upper  margins  of  the  orbit.  At  the  posterior  upper  margin  of  each  orbit  is  a  strong 
spine  pointing  backward  and  upward;  a  long  sharp  spine  at  the  upper  angle  of  the  opercu- 
lum, its  exposed  portion  as  li  »ng  as  half  the  diameter  of  the  eye.  Preoperculum,  on  its  lower 
posterior  border,  with  three  equidistant  spines,  much  weaker  than  that  of  the  operculum. 
Large  muciferous  cavities  in  the  bones  of  the  head;  a  row  of  large  cavities  extending  back 
ward  from  the  upper  angle  of  the  orbit,  and  continuous  with  those  on  the  lateral  line.  Mouth 
large,  its  cleft  considerably  longer  than  half  the  length  of  the  head,  and  the  maxillary 
extending  behind  the  vertical  from  the  posterior  margin  of  the  orbit.  The  posterior  portion 
of  the  maxillary  much  expanded,  its  width  at  the  end  equal  to  three-fourths  the  diameter 
of  the  eye.  Upon  its  expanded  tip  are  scales.  Eye  large,  one-fourth  as  long  as  head,  and 
as  wide  as  the  interorbital  space.    Length  of  head  one -fifth  standard  length. 

Dorsal  fin  inserted  at  a  distance  from  the  snout  equal  to  two-ninths  the  length  of  the 
body. 

Anal  inserted  under  the  vertical  from  the  twenty-fifth  or  twenty-sixth  dorsal  ray.  The 
height  of  the  dorsal  and  aual  fins  is  about  equal  to  the  diameter  of  the  eye.  Their  bases 
extend  almost  to  the  insertion  of  the  caudal. 

The  caudal  is  composed  of  0  or  7  rays;  its  length  equal  to  half  the  distance  from  the 
snout  to  the  insertion  of  the  dorsal. 

The  ventrals  inserted  almost  under,  but  slightly  posterior  to,  the  posterior  limb  of  the 
preoperculum,  in  length  about  equaling  the  upper  jaw. 

Pectorals  inserted  close  to  the  branchial  aperture;  the  eight  lower  rays  being  free  and 
much  prolonged,  the  longest  and  most  anterior  being  nearly  one-third  as  long  as  the  body, 
and  more  than  three  times  as  long  as  the  contiguous  posterior  ray  of  the  normally  con- 
structed portion  of  the  fin,  which  is,  however,  about  equal  to  the  last  of  the  free  rays.  The 
free  portion  of  the  pectoral  being  longer  and  composed  of  fewer  rays  than  the  normal  portion, 
the  fish  has  the  appearance  of  bearing  two  pectoral  fins  of  the  same  general  shape,  the 
lower  of  which  is  the  longer.  The  length  of  the  normal  portion  of  the  fin  is  contained 
about  four  times  in  the  length  of  the  body. 

Radial  formula:  D.  100;  A.  about  85;  C.  G  or  7;  V.  |;  P.  19+7  or  8.     L.  lat.  110-120.

The  lower  pectoral  rays  are  free,  not  united  by  membrane  with,  hut  inserted  on  the 
same  base  as  the  upper  part  of  the  fin.  They  are  but  slightly  stronger  than  the  other  rays 
and  prolonged.  IJody  elongate,  compressed,  covered  with  small,  very  thin  and  deciduous 
scales.  Head  slightly  compressed,  broad  and  flat  above,  depressed  in  front,  naked  (with 
the  exception  of  the  parts  between  the  mandibles,  and  perhaps  the  cheeks).  Bones  thin, 
with  the  muciferous  system  moderately  developed,  only  one  small  spine  above  on  the 
operculum;  preoperculum  without  spine.  Eye  small.  Vertical  fins  united,  but  the  narrow 
caudal  projecting  beyond  the  short  dorsal  and  anal  rays.  Ventrals  each  reduced  to  a 
filament,  which  consists  of  2  rays  firmly  bound  together  in  their  whole  length;  they  are 
inserted  behind  the  humeral  symphysis  and  close  together.  Snout  broad,  rounded,  scarcely 
overlapping  the  lower  jaw.  Mouth  very  wide;  villiform  teeth  in  the  jaws,  on  the  vomer 
and  palatine  bones.  Gill  -  lamina;  short;  gill-rakers  long,  not  very  closely  set.  Pseudo- 
branchiae  none. 

"  1  have  long  hesitated."  writes  Gilnther,  "  to  describe  this  fish  under  a  distinct  generic 
name.  The  specimen  is  small,  unique,  and  not  in  the  best  state  of  preservation,  so  that 
several  of  the  characters  assigned  here  to  the  genus  may  have  to  be  amended  when  other 
specimens  are  obtained.  Its  pertinence  to  either  Pteroidonus  or  Dicrolene  seems  to  be  doubt- 
ful on  accouut  of  the  difference  iu  the  shape  of  the  head."

Japan  and  not  certainly  known  to  be  bathybial. 

The  genus  Hoplobrotula  Gill  (Proc.  Acad.  Nat.  Sci.,  1803,  253)  was  established  for  another 
Japanese  form  (Brotula  armata,  Schlegel),  cited  by  Giinther  in  his  catalogue  under 
Sirembo.     It  is  not  certainly  known  to  be  bathybial. 

Vaillant  enlarges  the  limits  of  Sirembo  to  include  the  forms  here  discussed  under 
Sirembo,  Hoplobrotula,  Catcetyx,  Mixonus,  Bathyonus,  Porogadus,  ITematonus,  Diplacantho- 
poma,  and  Neobythites.  Vaillant's  Sirembo  is  a  congeries  of  heterogeneous  forms,  includ- 
ing, probably,  representatives  of  three  subfamilies. 


MONOMITOPUS,    Alcoek. 
Monomitopus,  Alcock,  Ann.  and  Mag.  Nat.  Hist.,  1890,  II,  L".'7. 

This  genus  differs  from  Sirembo  in  the  character  of  its  pseudobranchia?,  which  are 
rudimentary — "really  consisting  of  2  small  pinnules  only  on  each  side."  It  is  represented 
by  a  single  species,  obtained  by  the  Investigator  in  the  Andaman  Sea,  in  100  fathoms. 
(Sirembo  nigripinnis,  Alcock,  op.  cit.,  1889  (Nov.),  384.) 

TYPHLONUS,   Giinther. 
Typhlonus,  Ginther,  Ann.  and  Mag.  Nat.  Hist.,  1878,  217;  Challenger  Report,  xxn,  118. 

Head  large,  compressed,  with  most  of  the  bones  in  a  cartilaginous  condition;  the 
superficial  bones  with  large  muciferous  cavities  not  armed.  Snout  a  thick  protuberance 
projecting  beyond  the  mouth,  which  is  rather  small,  inferior.  Trunk  very  short,  the  vent 
being  below  the  pectoral;  tail  thin,  strongly  compressed,  tapering,  without  separate  cau- 
dal. Eye  externally  not  visible,  reduced  to  a  minute  rudiment  hidden  below  the  skin. 
Bands  of  villiform  teeth  in  the  jaws,  on  the  vomer  and  palatine  bones.  Barbel,  none. 
Veutrals  reduced  to  simple  filaments,  placed  close  together  on  the  humeral  symphysis. 
Gill  openings  very  wide,  the  gill  membranes  being  but  slightly  united  in  front.  Gills  4; 
gill  lamina'  rather  short;  gill  rakers  of  moderate  length;  scales  thin,  deciduous,  small. 

The  only  representative  of  this  genus  is  Typhlonus  nasits,  Giinther,  (Challenger  Report, 
xxu,  119,  PI.  xxv,  A.)  obtained  by  the  Challenger  at  station  181,  northeast  of  Aus- 
tralia, in  2,440  fathoms,  and  at  station  198,  north  of  Celebes,  at  the  depth  of  2,150  fathoms.

Barathronus  bieolor,  Goode  and  Bean,  Bull.  Mus.  Comp.  Zool.,  mi.  No.  r>,  164,  7. 

Body  much  compressed,  its  greatest  height  (19  millimeters)  contained  <>i  times  in  the 
total  length.  Head  much  thicker  than  body,  its  greatest  width  equal  to  \  of  its  length  (23 
millimeters),  which  is  contained  5|  times  in  the  total  length.  Eye  concealed  by  the  skin; 
diameter  of  orbit  about  equal  to  width  of  interorbital  area,  and  contained  I |  times 
in  length  of  the.  head.  Maxilla  extends  slightly  beyond  the  perpendicular  through  pos- 
terior margin  of  orbit;  it  is  almost  entirely  concealed  under  the,  preorbital,  and  is  much 
expanded  at  the  tip,  where  its  width  is  rather  greater  than  that  of  the  eye.  Intermaxilla 
very  thin,  broad,  and  slightly  protractile. 

Vomer  very  close  to  intermaxillary  symphysis,  its  head  somewhat  raised  and  bearing 3 
fang  like  teeth  {'1  of  which  are  off  one  side  and  1  on  the.  other  in  the  type,  separated  by  a 
moderately  wide  interspace).  The  mandible  has  five  enlarged,  separate,  recurved  teeth 
upon  each  side,  which  increase  in  size  posteriorly;  its  upper  edge,  posteriorly,  is  produced 
above  the  level  of  the  tooth-bearing  surface,  and  is  received  under  the  expanded  maxilla. 
The  longest  gill-raker  is  about  as  long  as  the  eye.  The  dorsal  origin  is  distant  from  the 
snout  (54  millimeters),  which  is  contained  slightly  less  than  twice  in  the  total  length.     The 

rays  are  well  developed,  numerous,  long  and  slender,  about  7l>  in  number;  the  longest  < 

tabled  about  •'!  times  m  the  length  of  head. 

The  anal  originates  in  vertical  from  fourteenth  dorsal  ray,  equidistant,  from  eye  and 
base  of  caudal.     It  contains  57  rays,  about  as  long  as  those,  in  the  dorsal. 

The  pectoral  with  a  fleshy  base,  its  length  (18  millimeters)  a  little  less  than  height  of 
body. 

The  ventral  well  in  advance  of  pectoral,  close  to  humeral  symphysis,  the  rays  being 

placed  very  close  together  at  their  origin,  the  length  of  the  fin   (13  millimeters)  < tained 

about  '•»  times  in  the  total  length,  about  3  times  in  distance  from  its  origin  to  the  vent. 

The  caudal  has  about  10  rays;  its  length  is  contained  about  8  times  in  the  total  length. 

Color,  yellowish  white,  with  a  broad  vertical  band  of  black  from  the  origin  of  ventral 
nearly  to  the  vent;  another  similar  and  narrower  band  above  it  upon  each  side.

gill-laminae.  Head  covered  with  a  system  of  wide  muciferous  channels  and  sinuses,  the 
dermal  bones  being-  almost  membranaceous,  whilst  the  others  are  in  a  semicartilaginous 
condition.  Notochord  persistent,  but  with  a  superficial  indication  of  the  vertebral  segments 
(as  in  some  Leptocephaline forms).     (Giinther.) 

This  genus  is  known  from  two  species — A.  mollis,  Goode  and  Bean,  and  the  type,  A. 
gelatinosus,  Giinther  (Challenger  Report,  xxn,  1887, 120,  pi.  xxvi,  Fig.  A)  from  station  184,

in  maxillary;  not  visible  to  the  eye,  but  appreciable  to  the  touch.  Gill-lamina?  on  the  fourth 
and  rudimentary  gill-rakers,  8  rudiments  and  4  developed  below  the  angle.  Dorsal  origin 
almost  over  posterior  edge  of  operculum,  its  distance  from  the  snout  \  of  total  length;  tin- 
rays,  more  than  110  well  developed,  the  longest  3  in  head.  Anal  origin  slightly  nearer  base 
of  caudal  than  to  tip  of  snout,  its  rays  shorter  than  those  in  the  dorsal.  Pectoral  with  a 
fleshy  base;  its  origin  somewhat  behind  that  of  the  dorsal,  its  length  equal  to  width  of  head. 
Ventral  origin  in  advance  of  that  of  pectoral,  close  to  humeral  symphysis;  the  fin  is  a  sin-

Body  elongate,  compressed  (especially  posteriorly),  its  greatest  height  being  scarcely 
one  sixth  cif  the  thickness  above  the  pectorals,  and  one-eighth  of  the  total  length. 

Length  of  head  one  sixth  of  total  length;  its  globular  form  gives  it  a  very  singular  ap- 
pearance, suggestive  of  Uranoscopus  and  Synanceia.  The  head  appears  as  if  it  wen- truncated 
Lnfront;  the  snout  occupies  the  upper  portion  of  the  truncation.  The  mouth  is  shaped 
like  a  horseshoe  and  is  placed  vertically,  the  lower  jaw  being  entirely  outside  of  the  open

as  long  as  the  maxillary,  which  is  expanded  at  its  posterior  extremity. 

Teeth  fine,  uniform  in  size,  upon  the  mandible  and  on  the  anterior  portion  of  the  inter- 
maxillary. No  teeth  visible  upon  the  vomer  or  palatines.  The  eye  is  rudimentary,  very

BELLOTTIA  APODA,  Giglioli. 

Belloitia  apoda,  Giglioli,  Zoologisclier  Anzeiger,  vi,  399. 

The  vent  equidistant  from  the  tip  of  the  snout  and  root  of  the  tail.  Dorsal  origin  in 
the  vertical  from  the  middle  of  the  pectorals,  confluent  with  the  caudal  and  the  anal.  Pec- 
torals normal  and  small.  Body  covered  with  mucous  pores  particularly  conspicuous  upon 
the  head.  Anal  papilla  sometimes  present.  Lateral  line  simple,  slightly  arched  over  the 
pectorals,  straight  and  median  posteriorly.  Two  cutaneous  folds  parallel  to  the  base  of 
the  dorsal.    The  central  rays  of  the  caudal  are  the  longest. 

Radial  formula  (estimated):  D.  90;  A.  75;  0.  12. 

Color,  olive  gray,  with  minute  dots  of  black;  lins  black  at  the  base,  colorless  and 
transparent  elsewhere. 

The  two  types  measure  28  to  30  millimeters.  Five  specimens  of  this  form  were  taken 
in  the  net  in  the  Gulf  of  Naples  in  December,  1882,  at  the  depth  of  30  meters.  Two  of 
them  (the  types  of  this  description)  are  in  the  Italian  collection  of  the  Royal  Zoological 
Museum  at  Florence;  two  more  in  the  Museo  Civico  at  Milan;  the  fifth  in  the  Zoological 
Station  in  Naples. 

Although  not  yet  found  at  considerable  depths,  its  affinities,  in  the  opinion  of  Giglioli 
and  Viuciguerra,  appear  to  be  with  the  family  B  rot  ul  id  a,  and  the  genus  is  admitted  to  this 
work  not  only  for  the  purpose  of  comparison,  but  in  the  belief  that  it  will  eventually  be 
found  in  deep  water.

Head  large,  with  thin,  smooth,  uncrested  bones,  scaleless.  No  armature  but  a  weak 
opercular  spine.  Body  compressed,  tapering,  covered  with  deciduous  cycloid  scales.  Eye 
moderate.  Snout  not  overhanging  the  jaws.  Mouth  with  obliquely  ascending  cleft,  and 
with  the  lower  jaw  prominent.  Yilliform  teeth  in  the  jaws,  palatines,  and  vomer.  No 
barbel  orhyoid  filaments.  Gill-openings  wide;  gill-membranes  separate,  4  gills;  no  pseudo 
branchiae;  8  branchiostegals.  Lateral  line  indistinguishable.  Vertical  tins  confluent; 
pectoral  fins  entire;  no  ventral  fins. 

The  type,  //.  si mn hi,  was  described  from  an  immature  specimen,  8  inches  long,  taken 
by  the  Investigator  off  the  Coromandel  coast,  in  902  fathoms. 

LAMPROGRAMMUS,   Alcock.     (Figure  302.) 
Lamprogrammxis,  Alcock,  Ann.  and  Mag.  Nat.  Hist.,  vin,  1891,  32. 

Head  large,  body  compressed,  both  entirely  covered  with  thin,  smooth,  deciduous 
scales  of  moderate  size.  Head  bones  with  prominent  crest  and  wide,  muciferous  cavities, 
unarmed  except  for  a  weak  opercular  spine.  Snout  not  overhanging  the  jaws.  Eye  of 
moderate  size.  Mouth  large;  teeth  in  villiform  bands  in  the  jaws,  palatines,  and  vomer. 
No  barbel  or  hyoid  filaments.  Gill-opening  wide;  gill  membranes  separate;  4  gills,  8 
branchiostegals,  no  pseudobranchiae.  Lateral  line  very  conspicuous,  with  much  enlarged 
scales,  each  of  which  bears  a  glandular  (luminous)  organ.  Vertical  fins  confluent;  pectoral 
fins  entire;  no  ventral  fins.     {Alcock.) 

This  genus  is  represented  by  the  single  species,  Lamprogrammus  niger,  Alcock  (loc.  cit, 
fig.  2),  described  from  two  specimens,  11|  and  15  inches  in  length,  obtained  by  the  Investi- 
gator in  the  Andaman  Sea,  at  a  depth  of  5G1  fathoms,  and  another  from  404  fathoms  in 
the  same  region.  Alcock  says  of  it:  "This  extraordinary  form  seems  almost  entitled  to 
rank  by  itself  in  a  separate  subfamily  of  the  Ophidiidas.  In  general  appearance  and  in 
most  of  its  structural  details  it  has  the  closest  resemblance  to  the  typical  lirotidituv;  but 
it  differs  from  them  all  in  its  remarkable  Halosaurus  like  lateral  line  and  in  the  entire 
absence  of  ventral  fins."

346  DEEP-SEA    FISHES   OF   THE   ATLANTIC   BASIN. 

Head  with  imbricated  scales  extending  to  forehead:  opercula  and  cheeks  moderately 
compressed,  oblong-ovate  in  profile,  with  the  snout  high,  projecting  forward  and  obtusely 
rounded,  armed  above  with  a  short,  nearly  concealed  spine,  directed  forward  and  somewhat 
downward.  Cheeks  somewhat  inflated.  Eyes  large,  subcircular,  with  comparatively  small 
pupils.  Nostrils  double;  the  anterior  aperture  a  short  tube  directed  forward  and  next  to 
the  groove  separating  the  preorbital  from  the  nostril  region;  the  posterior  a  longitndinal 
groove,     Opercula  unarmed. 

Mouth  broader,  with  the  cleft  little  oblique  and  moderate;  thestiperinaxillary  bones  are 
slender,  terminate  under  the  hinder  part  of  the  eye,  and  are  almost  wholly  retractile  under 
the  suborbitals. 

Teeth  of  the  jaws  villiform,  immersed  in  a  mucous  membraue,  separated  by  an  interval 
from  the  longer  ones  in  the  outer  row,  which  are  pointed  and  movable. 

Vomer  not  prominent,  armed,  as  well  as  the  palatine  bones,  with  teeth. 

Branchial  aperture  ample,  arched  above  by  the  membrane,  which  is  attached  in  front 
of  the  axil  of  the  pectoral  fin. 

Branchiostegal  rays  seven,  the  internal  two  small. 

Dorsal  fin  commencing  less  than  a  head's  distance  from  the  nape,  rather  low  and  with 
its  rays  simply  articulated,  blending  behind,  like  the  anal,  with  the  caudal  fin,  whose  rays 
are  longer  than  those  of  the  dorsal  and  anal,  and  whose  margin  is  produced. 

Pectoral  fins  small  or  moderate,  obliquely  rounded  behind. 

Ventral  fins  bifid  and  articulated,  and  much  abbreviated. 

This  genus  is  exceedingly  distinct  from  Ophidium,  having  very  few  characters  in  com 
mon,  except  such  as  would  be  found  in  the  genera  of  the  same  subfamily.  Its  form  at  once 
distinguishes  it,  its  comparatively  low  and  moderately  compressed  body  and  smaller  head 
contrasting  strongly  with  the  much  compressed  body  and  head  of  the  true  Ophidiidas.  The 
imbricated  scales  and  peculiar  dentition  observed  on  closer  examination  corroborate  the 
generic  distinction  indicated  by  difference  of  form.1

Body  elongate,  slender,  its  greatest  height  (25  millimeters  in  specimen  examined)  10i 
in  its  total  length. 

Head  slender,  somewhat  compressed,  its  length  (40  millimeters)  (>J  in  total  length. 
Interorbital  area  broad,  convex,  its  width  equal  to  the  length  of  the  snout  and  5§  in  head's 
length.  Snout  sharp,  conical,  armed  with  a  short  but  sharp  spine,  and  somewhat  over- 
hanging the  mouth.  Eye  circular,  its  diameter  (10  millimeters)  4  in  head's  length,  and 
much  exceeding  the  length  of  the  snout.  Maxilla  extending  nearly  to  the  vertical  through 
the  posterior  margin  of  the  orbit,  its  length  (15  millimeters)  three-eighths  of  head's  length. 
Mandible  extending  behind  the  same  vertical,  its  length  (IS  millimeters)  equal  to  that  of 
head  without  its  postorbital  portion.  Jaws,  vomer,  and  palatines  with  narrow  bands  of  vil- 
liform teeth,  some  of  which  are  noticeably  enlarged  (not  movable).     Pseudobranchiae  present. 

1  It  is  probable  that  the  Ophidium  brevibarbe,  briefly  indicated  by  Cuvier  and  Kaup,  belongs  to  this 
genus;  by  Cuvier  it  was  simply  alluded  to  in  a  foot-note  of  the Regne  Animal,  while  by  Kaup  a  short 
diagnosis  was  given  in  the  "Catalogue  of  the  Apodal  Fish."  As  the  notice  of  the  species  by  Kaup,  like 
most  of  the  diagnoses  by  that  gentleman,  is  only  sufficient  to  distinguish  it  from  species  known  to  him,  uo 
clear  idea  can  be  obtained  regarding  its  affinities.     Gill.

The  greatest  height  equals  about  a  tenth  of  the  extreme  length,  and  is  developed  at 
the  pectoral  region;  it  thence  almost  uniformly  decreases  to  the  end,  and  at  the  aims  equals 
one-eleventh  of  the  same:  the  thickness  behind  the  pectoral  fins  equals  seven-tenths  of  the 
height,  and  almost  uniformly  decreases  to  the  end  like  the  height.  The  anus  is  at  the  end 
of  the  first  third  of  the  length. 

The  head  forms  rather  less  than  a  sixth  of  the  length,  and  is  transversely  convex  above 
and  moderately  inflated  on  the  sides;  the  greatest  width  equals  half  its  length.  The  eye  is 
rather  longer  than  the  snout,  subcircular,  and  its  diameter  slightly  exceeds  two-sevenths 
of  the  head's  length;  its  pupil  is  small,  the  diameter  equaling  only  a  third  of  that  of  the 
eye.  The  width  of  the  interocular  region  rather  exceeds  two  ninths  of  the  head's  length. 
The  snpramaxillary  ends  behind  under  the  hinder  margin  of  the  pupil. 

The  dorsal  fin  commences  nearly  over  the  middle  of  the  pectoral  fin,  and  with  the  sec 
ond  fifth  of  the  length  and  is  moderately  high;  the  anal  commences  immediately  behind  the 
anus,  and  is  about  as  high  as  the  dorsal:  the  caudal  rays  of  the    fin  are  the  longest,     'flic 
pectoral  tin  little  exceeds  half  the  head's  length,  and   the   longest    branch   of  the  ventral  is 
less  than  a  third  of  the  head's  length,  and  three  fifths  greater  than  the  shorter.

Gunther  is  of  the  opinion  that  the  "Lophotas"  are  deep-sea  fishes  like  the  Ribbon 
fishes,  but  that  they  do  not  descend  to  the  greatest  depths,  their  bony  and  soft  parts  being 
firm  and  coherent.

Lophotus  Lacipidr,  Kisso.  Ili^t.  Nat.  Europe  Mfcridionale,   1829,  293. 

A  Lophotes  with  the  height  of  the  body  contained  7  times  in  its  total  length;  its  thick- 
ness 21  times.  The  skin,  which  is  naked,  is  roughened  by  very  minute  furrows.  The 
vent  is  very  far  back,  near  the  extremity  of  the  body.  The  head  is  very  singular  in  its  form, 
being  elevated  in  front  in  a  triangular  crest]  exceedingly  sharp,  and  surmounted  by  a  lone, 
compressed  spine,  which  corresponds  to  the  first  ray  of  the  dorsal.  Snout  short;  mouth 
small,  not  protractile,  subvertical.  Teeth  cardiform  upon  the, jaws,  the  vomer  and  pala- 
tines being  also  dentigerous.     Eyes  very  large,  their  diameter  about  one  third  of  the  length

of  the  head.  The  opercular  bones  are  somewhat  striated.  The  lateral  line  extends  from 
the  crest  to  the  caudal,  describing  a  downward  curve  in  front  of  the  gill-opening.  The 
dorsal  begins  upon  the  top  of  the  head  and  in  advance  of  the  eyes,  and  terminates  near  the 
caudal,  and  contains  more  than  200  rays;  the  tins  are  very  short  and  very  far  back.  The 
caudal  is  very  small.  The  pectorals  arc  moderate,  placed  near  the  lower  outline  of  the 
body.     Yeutrals  minute.

Color  silvery  gray,  with  rounded  spots  of  silver,which  arc  brighter  than  the  body  itself; 
fins  a  brilliant  rose  color. 

This  species  was  first  described  by  Prof.  Giorna,  who  brought  it  before  the  Acad- 
emy of  Turin  in  1803.  His  description  was  not  complete,  but  Cuvier  in  1813  received  one 
from  the  Gulf  of  Genoa,  and  published  a  most  exact  description  of  it  in  the  Annals  of  the 
Paris  Academy  of  Sciences,  accompanied  by  a  drawing  by  Laurillard,  of  which  a  facsimile 
is  here  presented.    The  measurements  of  this  specimen  were  as  follows:

Specimens  have  since  been  taken  in  various  parts  of  the  Mediterranean.  The  Florence 
Museum  has  a  beautiful  specimen,  taken  at  or  near  Elba  Island  in  181S.  Prof.  Giglioli  has 
also  seen  individuals  from  Xice,  Genoa,  and  Palermo. 

LOPHOTES  CRISTATUS,  Johnson. 

Lophotes  cristatus,  Johnson,  Proc.  Zool.  Soc,  1863,  38. 

A  Lophotes  with  elongate,  compressed,  blade-like  body,  its  height  contained  5}  times 
in  its  length,  its  thickness  over  30  times.  The  line  of  the  unarmed  belly  is  nearly  straight. 
The  back  curves  upwards  slightly  for  the  first  third  of  the  Length  of  the  fish  and  then  slopes 
gently  to  the  tail.  The  body  clothed  with  small  scales,  which  arc  buried  in  the  skin  and 
set  obliquely  so  as  to  give  a  reticulate  appearance.     Scales  large  and  very  delicate.

Color,  uniform  silvery  gray,  without  spots. 

This  species  was  obtained  by  Mr.  J.  Y.  Johnson  in  Madeira,  and  described  by  him  in 
1S63.    The  characters  pointed  out  by  him  seem  to  indicate  that  it  is  specifically  dist in 
guished  from  L.  Cepedianus,  but  the  material  available  for  study  has  been  so  slight  that  no 
definite  conclusion  can  now  be  reached.     Since  no  figure  of  this  species  has  been  published, 
the  complete  description  is  here  included: 

The  head  is  short  and  unarmed;  it  bears  a  high  fleshy  crest,  the  horizontal  line  of  which 
is  straight  with  the  back.  This  crest  carries  the  anterior  portion  of  the  dorsal  fin,  and  it 
projects  at  an  acute  angle  beyond  the  vertical  of  the  snout.  At  the  angle  rises  a  single 
bony  ray,  which  is  equal  in  length  to  one-fourth  of  the  total  length  of  the  fish.  A  fringe 
of  red  membrane  connects  it  with  the  dorsal  fin,  of  which  it  appears  to  be  the  first  ray. 
The  edges  of  the  gill-covers  are  simple,  the  bones  radiate-striate.  The  round  eye  is  large, 
its  diameter  being  contained  '■'<  times  in  the  head;  the  iris  is  silvery  white,  the  pupil  oval. 
The  space  intervening  between  it  and  the  front  of  the  head  above  the  jaw  is  much  less  than 
a  diameter;  but  the  space  between  the  edge  of  the  capital  crest  and  the  superior  part  of 
the  head  is  considerably  more  than  a  diameter.  The  space  between  the  eye  and  the  snout 
is  reddish  and  scaleless.  The  mouth  is  oblique  and  rather  small;  the  rictus  about  two- 
thirds  the  diameter  of  the  eye.  and  its  width  almost  equal  to  a  diameter.  There  are  about 
4  rows  of  small,  conical-pointed  teeth,  which  curve  backwards  at  the  front  of  the  premax- 
illary;  and  about  2  rows  of  similar  teeth  at  the  sides  of  the  lower  jaw,  whilst  in  front  they 
are  crowded  i  or  5  deep.  Small  teeth,  very  few  in  number,  are  planted  on  the  vomer  and 
on  the  anterior  extremities  of  the  palatine  bones ;  but  there  are  none  on  the  tongue.  Inside 
the  mouth,  above  and  below,  there  is  stretched  a  black  membrane  from  side  to  side.  The 
maxillary  is  toothless  and  is  much  dilated  below.  It  covers  the  premaxillary  at  the  sides, 
and  reaches  back  to  the  vertical  through  the  middle  of  the  eye.

Tlic  single  dorsal  I'm  extends  from  die  capital  crest  to  the  caudal  I'm.  from  which  it 
is  not  easily  distinguished.  Behind  the  long,  bony  ray  already  mentioned  it  is  low,  the 
middle  portion  being  higher  than  the  rest.    The  base  is  sheathed  in  transparenl  membrane, 

an  extension  of  the  skin.  The  pectoral  tins  are  of  moderate  size,  placed  low  down,  anil  at 
a  distance  from  the  tip  of  the  lower  jaw  equal  to  about  an  eighth  of  the  total  length  of  the 
fish.  The  firs!  raj  is  bony  and  very  strong,  but  not  longer  than  the  rest,  which  are 
branched.  The  ventral  tins  are  very  short,  and  are  inserted  a  little  behind  the  pectoral 
fins,  and  only  slightly  below  them.  Only  five  slender,  simple  rays  were  counted  in  the 
specimen.  The  anal  tin  is  low,  it  is  placed  far  behind,  near  the  caudal  I'm,  and  its  first 
three  or  four  rays  are  short.     The  vent  is  placed  just  before  the  tin.     The  tail  behind  I  he 

anal  fin  has  parallel  margins,  and  is  much  < ipressed.     It   is  low,  and  its  lower  edge  is 

finless,  whilst  its  upper  edge  carries  the  posterior  portion  of  the  dorsal  tin.  The  caudal 
fin  is  short,  and  is  not  well  distinguished  from  the  dorsal  fin;  but  there  seem  to  be  fifteen 
rays,  viz,  Id  below  the  lateral  line  and  5  above.  The  lower  angle  only  projects.  This  tin 
is  not  set  bliquely,  as  in  some  of  the  genera  of  the  family. 

The  unarmed  lateral  line  descends  at  an  angle  of  15  from  the  angle  of  the  capital 
crest  to  behind  the  eye;  it  is  then  straight  along  the  body  to  the  base  of  the  caudal  fin. 

The  stomach  is  csecal,  narrow,  and  tapers  downwards.  Numerous  caeca  are  attached  to 
the  intestine.  The  intestinal  canal  is  long  and  straight;  the  egg-sac  long  and  forked;  the 
liver  of  moderate  size.

A  Lophotes  having  the  length  of  the  head  equal  to  the  height  of  the  body,  and  con- 
tained about  7  times  in  total  length.  The  eyes  very  large,  their  diameter  contained  ■>\ 
times  in  the  length  of  the  head;  the  eye  nearer  to  the  throat  than  to  the  back.  The  angle 
of  the  head  in  front  somewhat  less  acute  than  in  L.  Cepedianus.  The  length  of  the  snout 
slightly  less  than  the  diameter  of  the  eye.  Mouth  moderate,  the  tip  of  the  maxillary 
reaching  to  the  vertical  from  the  anterior  margin  of  the  orbit.  Teeth  similar  to  (hose  of 
the  European  species.  Edge  of  preoperculum  rounded,  with  a  somewhat  acute  angle. 
The  operculum  rounded,  its  upper  edge  a  little  emargiiiate.  Opercular  bones  finely  striate. 
Body  absolutely  naked.  The  lateral  line  is  straight,  but  in  front  of  the  eye  ascends  in  a 
gentle  curve  to  the  tip  of  the  crest  and  the  base  of  the  first  dorsal  ray.  Vent  at  the  be. 
ginning  of  the  last  eighth  of  the  total  length  of  the  body;  the  anal  I'm,  placed  behind  it, 
is  rounded,  and  the  length  of  its  base  twice  as  great  as  its  height,  the  height  being  not 
more  than  half  the  vertical  diameter  of  the  orbit.  The  caudal  is  small,  its  length  being 
one-third  of  the  height  of  the  body,  it  being  considerably  larger  in  proportion  than  in  L. 
Cepedianus.  Dorsal  confluent  with  the  caudal  (not  confluent  in  /,.  Cepedianus);  its  height 
in  the  middle  is  equal  to  one-fourth  of  the  height  of  the  body,  but  it  decreases  in  height 
considerably  posteriorly  and  anteriorly,  so  that  over  the  eye  the  rays  arc  scarcely  percepti-

ble  above  the  skin.  The  seven  anterior  rays  are  longer,  however,  forming  a  sickle-shaped 
tin  almost  separate  from  the  main  dorsal  fin  in  advance;  the  first  ray  is  nearly  4  times  as 
high  as  the  second,  its  height  nearly  equal  to  that  of  the  body;  this  ray  is  spinous,  and 
thicker  than  the  others,  but  smaller  than  in  L.  Cepedianus,  and  very  sharp.  The  pectorals 
are  placed  very  low  down,  close  to  the  gill-opening.  The  veutrals,  as  in  the  European 
species,  are  very  minute,  and  placed  directly  under  the  posterior  edge  of  the  pectoral.

Color,  pale  blue,  becoming  white  on  the  lower  parts  and  blackish  blue  upon  the  head; 
the  fins  are  pale  blood  red;  the  iris  of  the  eye  is  silvery  white,  shaded  with  bluish. 

This  species  seems  to  be  well  distinguished  from  those  of  the  Atlantic  and  Mediterra- 
nean, having  a  lower  frontal  crest;  the  first  dorsal  fin  almost  completely  differentiated;  the 
dorsal  confluent  with  the  anal;  the  mouth  much  less  vertical,  and  with  very  different 
coloration.  The  species  was  obtained  by  Mr.  Burger  in  Japan,  and  by  him  a  figure  and 
certain  notes  appear  to  have  been  made.  The  figure  has  the  appearance  of  being  an  exact 
one,  and  it  would  seem  impossible  to  reconcile  it  with  the  Atlantic  forms. 

The  fish  must  be  exceedingly  rare  in  Japanese  waters.  We  have  been  unable  to  find 
any  traces  of  it  in  the  numerous  drawings  of  Jaiiauese  fishes  by  native  artists  which  we 
have  examined.

Anacanthine  fishes,  with  elongate,  posteriorly  concoidal  body;  isocercal  tail;  scales 
cycloid  and  small,  sometimes  wanting.  Head  large,  with  terminal  mouth.  Gill-openings 
wide;  gill  membranes  usually  free  from  isthmus.  Vertical  fins  well  separated.  Dorsal 
fin  in  one,  two,  or  three  sections,  the  latter — as  well  as  the  anal,  which  is  also  sometimes 
divided  into  two — sometimes  united  with  the  caudal.  Veutrals  subjugular.  Gills  4,  a  slit 
behind  the  fourth.  No  pseudobranchia;.  Pyloric  caeca  usually  numerous,  but  sometimes 
few  in  number  or  absent. 

There  is  a  general  resemblance  between  this  family  and  the  Brotulidce.  Indeed  Jordan 
and  Gilbert  make  the  Brotulids  a  subfamily  of  Gadida:    "We  follow  Gill  for  the  present. 

The  Brotulids  may  be  most  readily  distinguished  by  the  veutrals  which  are  always

is  contained  7  times  in  the  length  of  the  head  and  twice  or  less  in  the  interorbital  space. 
Color,  greenish,  brownish,  or  reddish  olive,  with  numerous  spots  on  the  back  and  sides; 
lateral  line  pale;  fins  dark. 

Radial  formula:  D.  14-21-19;  A.  20-18. 

The  species  is  subject  to  considerable  modifications  in  form  and  color. 

The  time-honored  name  Gadus  morrhua  is  retained.  We  can  not  assent  to  the  sub- 
stitution of  the  name  G.  callarias,  which  was  based  upon  young  specimens,  and  which, 
having  been  printed  upon  the  same  page,  is  in  no  real  sense  a  prior  name. 

The  cod  occurs  in  great  numbers  below  the  100-fathom  limit  on  both  sides  of  the  North 
Atlantic,  and  has  been  reported  by  the  New  England  fishermen  on  the  off-shore  banks  at 
a  depth  of  250  fathoms.  The  Albatross  obtained  it  from  station  20S2,  in  41°  9'  50"  N.  lat., 
66°  31'  50"  W.  Ion.,  at  a  depth  of  49  fathoms.

A  Gadoid  with  compressed  conical  head  and  a  long  and  narrow,  somewhat  compressed, 
snout.  Mouth  small,  maxillary  scarcely  reaching  to  the  line  from  the  anterior  margin  of 
orbit.  Length  of  head  equal  to  or  greater  than  the  height  of  body,  and  contained  three 
and  four-fifths  times  in  the  total  length  Teeth  large,  nearly  equal  in  size,  in  a  cardiform 
band  in  upper  jaw,  in  a  single  series  in  lower  jaw  and  on  vomer.  Eye  very  large,  its  di- 
ameter one-fourth  the  length  of  the  head.  Vent  in  vertical  form  oriein  of  second  dorsal  fin. 
First  dorsal  fin  triangular,  its  anterior  portion  much  elevated,  its  length  three-fourths  that 
of  the  head.  The  two  anal  tins  separated  by  an  interspace.  Color,  gray  above,  whitish 
below,  lateral  line  black;  a  large  dark  blotch  above  the  pectorals;  vertical  tins  dark. 

A  specimen  of  this  species  was  obtained  by  the  Albatro.ss,  from  station  2078,  in  41°  11' 
30"  N.  lat,  66">12'  20"  YV.  Ion.,  at  a  depth  of  499  fathoms— or,  at  all  eveuts,  the  specimen 
examined  by  us  bears  that  inscription.  It  is  almost  incredible  however.  Another  (Cat. 
No.  28743,  U".  S.  N.  M.)  is  said  to  have  come  from  station  918  of  the  Fish  Hawk,  in  40°  20' 
24"  N.  lat.,  70°  41'  30"  W.  Ion.,  at  a  depth  of  40  fathoms.

Caudal  separate:  three  dorsal  and  two  anal  tins;  vcntralsol'  seven  rays.     Branchiostegals, 
seven.     No  barbel. 

This  genus  has  the  general  appearance  of  Gadus,  but  is  distinguished  by  the  absenceof 

teeth  on  the  vomer.

(tail). 

A  Gadoid,  having  a  body  similar  in  form  to  that  of  Gadm;  its  height  one-fourth  of  its 
length,  and  its  thickness  one- seventh. 

Length  of  head  one-third  of  total  length;  snout  short,  its  length  less  than  one-fourth 
that  of  the  head.  Mouth  moderate,  oblique;  the  maxillary  extending  a  little  beyond  the 
vertical  from  the  anterior  limb  of  the  eye.  The  lower  jaw  is  longest.  Teeth  in  jaws  in  vil 
litbrm  bands;  palatines  and  tongue  without  teeth.  Vomer  unarmed,  except  occasionally  in 
individuals  which  have  two  or  three  minute  asperities  upon  its  angles.  Diameter  of  the 
eye  one-third  that  of  the  head;  width  of  interorbital  space  one-seventh. 

This  species  was  taken  by  II.  M.  S.  Porcupine  off  the  west  coast  of  Ireland  (hit.  51  in 
N".,  Ion.  10°  59'  TV.),  at  the  depth  of  183  fathoms.  It  had  previously  been  found  in  the  Med- 
iterranean, but  the  Travailleur  obtained  it  again  in  1882  in  the  Gulf  of  Gascony  (station 
viii^  at  111  meters  in  great  abundance,  50  specimens  being  brought  in  at  one  haul.  The 
Talisman  got  it  off  Morocco  at  510-550  meters  (stations  vm  and  xvn)  and  off  Soudan  in 
410  meters  (station  lxix).    It  is  yet  to  be  found  in  the  Western  Atlantic.

A  Gadoid  with  body  rather  slender.  Lower  jaw  longest  and  teeth  in  the  outer  series 
strongest.  The  vent  in  vertical  from  origin  of  first  dorsal.  Dorsal  tins  separated  by  great 
interspaces,  the  two  anterior  short.  Anal  fins  very  long.  No  barbel.  A  black  spot  in 
axil  of  pectoral. 

Radial  formula:  D.  12-13 +13-11 +24;  A.  36-38+24-25. 

This  codfish  occurs  on  the  west  coast  of  Norway  up  to  the  Polar  Circle  and  beyond, 
and  as  deep  as  100  fathoms.  It  is  numerous  in  October  and  November  in  the  Christ  iania 
Fiord  (hit.  60°),  according  to  Collett.  It  has  been  found  as  far  north  as  Bodoe  (67°). 
Strangely  enough,  ii  has  not  yet  been  distinguished  on  the  New  England  coast.  It  is  more 
than  probable  that  it  will  yet  be  found  among  the  captures  of  the  cod  schooners  of  the  off- 
shore banks.

358  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

The  distribution  of  this  species  is  very  puzzling.  It  has  been  found  at  Halifax,  Nova 
Scotia,  and  south  as  far  the  Cape  Fear  Eiver,  where  specimens  were  taken  in  shallow  water 
in  March,  1880,  by  Col.  Marshall  McDonald.  It  has  been  found  also  in  the  York  Eiver, 
Virginia,  a  tributary  of  Chesapeake  Bay,  but  is  nowhere  abundant  except  about  Long  Isl- 
and. It  has  also  been  found  at  considerable  depths,  as  is  shown  in  the  following  list:  By

Mr.  A.  Agassiz  and  the  officers  of  the  Blake  had  their  attention  forcibly  attracted  to  a 
singular  power  possessed  by  this  fish  of  emitting  electric  shocks.  This  peculiarity  has 
never  been  noticed  in  this  species  save  in  deep  water.  The  attention  of  observers  is  called 
to  this  interesting  point. 

PHYCIS  CIRRATUS,  Goode  and  Bean,  n.  8.     (Figure  310. 1 

The  body  is  moderately  stout ;  its  greatest  height  equals  the  length  of  the  head  without 
the  snout  and  is  contained  5  times  in  the  length  to  base  of  caudal.  The  length  of  the  head 
is  one-fourth  of  the  standard  length.  The  eye  is  large,  its  length  in  the  largest  specimen 
examined  slightly  more,  and  in  the  smallest  individual  slightly  less,  than  one-fourth  that  of 
the  head.  The  width  of  the  interorbital  space  is  about  one-half  the  length  of  the  eye  in  large 
examples.  The  maxilla  does  not  reach  to  the  posterior  margin  of  the  orbit  in  large  speci- 
mens, but  in  the  smallest  one  it  extends  fully  to  that  vertical.  The  mandible  extends  far 
beyond  the  posterior  margin  of  the  eye,  and  its  length  is  about  equal  to  the  postorbital  part 
of  the  head.  The  barbel  is  minute  in  all  the  examples  examined;  its  length  usually  about 
one-fifth  that  of  the  eye.  Teeth  in  villiform  bands  in  both  jaws,  the  intermaxillary  bauds 
being  wider  than  those  on  the  mandible.  Vomerines  in  a  narrow,  villiform  band.  Gill- 
rakers  2+12.  The  largest  ones  club-shaped  at  the  end:  the  longest  one-fourth  as  long  as 
the  eye.    Gill  membranes  attached  to  the  isthmus,  but  with  a  narrow,  free  posterior  border. 

The  length  of  the  pectoral  equals  about  one  half  the  distance  from  the  ventral  to  the 
anal  origin.  It  reaches  to  about  the  twenty-sixth  row  of  scales.  The  ventral  reaches  in 
some  specimens  slightly  beyond  the  origin  of  the  anal.  In  one  individual  it  reaches  almost 
to  the  middle  of  the  anal  fin.  None  of  the  dorsal  rays  are  filamentous,  the  longest  rays  being 
contained  from  2i  to  3  times  in  the  length  of  the  head.  The  length  of  the  base  of  the  first 
dorsal  is  about  equal  to  the  length  of  the  eye  in  most  specimens;  in  smaller  examples  it  is 
somewhat  greater,  about  one-third  the  length  of  the  head.  The  vent  is  under  the  sixteenth 
ray  of  the  second  dorsal. 

Radial  formula!  D.  10+60;  A.  57;  Scales  6-93-20. 

Color  light  brown;  lower  parts  minutely  dotted.  Dorsals  with  narrow  dark  margins; 
caudal  with  a  broad  dark  margin;  anal  with  a  narrow  dark  margin  in  its  posterior  third. 
Roof  of  mouth  and  interior  of  gill-cavity  dark-brown.

Many  specimens  apparently  of  this  species  were  obtained  outside  of  the  hundred- 
fathom  curve.  The  Blake  secured  examples  from  station  cccxi,  in  39°  59'  30"  X.  hit..  To 
12'  W.  Ion.,  at  a  depth  of  143  fathoms,  and  from  station  CCCXLVI,  in  40  >  25'  35"  X.  hit..  71 
10' 30"  W.  Ion.,  at  a  depth  of  44  fathoms.  The  A Ibatross  obtained  specimens  from  station 
2420,  in  37°  3'  20"  K  lat.,  74°  31'  40"  W.  Ion.,  at  a  depth  of  104  fathoms;  from  station 
2539,  in  39°  59'  45"  N.  lat.,  70°  53'  \V.  Ion.,  at  a  depth  of  133  fathoms:  from  station  2537,  in 
39°  56' 45"  2*.  lat.,  70°  50' 30"  W.  Ion.,  a1  a  depth  of  134  fathoms:  and  from  station  2540, 
in  39°  58'  20"  X.  lat.,  70°  52'  W.  Ion.,  at  a  depth  of  1  1 1  fath s. 

This  is  a  common  species  along  the  coast  of  the  New  England  States  from  the  shoals 
south  of  Cape  Cod  to  the  Gulf  of  St.  Lawrence.  It  appears  to  bea  bottom-living  fish,rarely 
changing  locality.  It  is  believed  that  they  spawn  throughout  the  summer,  for  the  young 
fish  are  found  through  all  the  summer  months.  Specimens  taken  at  a  depth  of  37  fathoms 
in  a  temperature  of  41°F.  contained  well-developed  ova  and  were  apparently  ready  to  spa  \\  n. 
The  young  are  frequently  taken  swimming  on  the  surface  on  the  southern  coast  of  New 
England  in  the  summer,  and  numerous  individuals  have  been  found  off  Block  Island  and 
Watch  ITill,  seeking  shelter  between  the  valves  of  a  large  species  of  scallop  (Pecten  tenui- 
costatus)  at  a  depth  of  20  to  40  fathoms.  An  extensive  fishery  is  carried  on  in  winter  from 
Cape  Ann,  in  which  sometimes  as  many  as  fifty  vessels  are  engaged.  In  1878,  at  Glou- 
cester alone  5,000,000  pounds  at  least  of  this  and  the  related  species,  P.  tenuis,  were 
landed.  Fishing  is  carried  on  at  night  with  trawls  in  10  to  50  fathoms.  The  species  has 
been  found  oft' the  coast  of  Virginia  at  a  depth  of  300  fathoms.

Head  contained  in  body  (without  caudal)  J^  times,  height  of  body  5  times.  Diameter 
of  orbit  in  length  of  head  3.1-  times,  maxillary  twice.  Barbel  about  one-third  of  diameter  of 
orbit.  Vent  situated  under  12th  ray  of  second  dorsal,  and  equidistant  from  tip  of  snout 
and  end  of  second  dorsal.  Distance  of  dorsal  flu  from  snout  equal  to  twice  the  length  of 
the  mandible;  the  third  ray  of  the  first  dorsal  is  extremely  elongate,  extending  to  a  point 
(33d  ray  of  second  dorsal)  two  thirds  of  the  distance  from  snout  to  tip  of  caudal,  its  length 
more  than  twice  that  of  the  head,  and  more  than  four  times  as  long  as  the  rays  imme- 
diately preceding  and  following  it.  Anal  fin  inserted  immediately  behind  the  vent,  its  dis- 
tance from  the  root  of  the  ventrals  equal  to  that  of  the  dorsal  from  the  snout.  As  in  the 
other  species  of  the  genus,'  the  ventral  is  composed  of  3  rays,  the  first  two  much  pro- 
longed. The  first  is  contained  three  times  in  the  length  of  the  body,  the  second  is  almost 
three  times  as  long  as  the  head,  reaching  to  the  40th  anal  ray  or  f  of  the' distance  from 
snout  to  tip  of  caudal;  the  third  is  shorter  than  the  diameter  of  the  orbit. 

The  pectoral  is  four  times  as  long  as  the  operculum.  Scales  large  and  thin,  easily 
wrinkling  with  the  folding  of  the  thick,  loose  skin,  particularly  in  the  median  line  of  the

1 A  critical  study  of  the  ventral  fins  of  Phycis  compels  us  to  believe  that  the  ventral  fin  is  composed  of 
3  rays  covered  at  the  base  with  a  thick  skin  in  such  manner  as  to  obscure  the  third,  short  one,  and  to  join 
the  other  two  so  that  they  appear  like  a  single  bifid  ray.  In  young  individuals  of  Phycis  ohuss,  the  third 
ray  has  its  extremity  protruding  from  the  sheath,  though  in  adults  it  becomes  entirely  enveloped,  thus  giv- 
ing rise  to  the  false  definitions  which  have  been  given  for  this  genus.  An  adult  specimen  of  Phycis  furcutits 
Flem.  (No.  17371  of  the  National  Museum  collection),  has  the  third  ventral  ray  protruding.

Numerous  specimens  of  this  lish  were  taken  at  various  depths.  These  collections  con- 
firm the  view  expressed  after  a  study  of  the  collections  made  by  the  Fish  Commission  in 
tlic  same  year;  namely,  that  Phycis  Ghesteri  and  Macrurus  Bairdii  appear  to  be  the  must 
abundant  fishes  on  the  continental  slope  from  140  to  500  fathoms,  occurring  in  immense 
numbers  and  breeding-  copiously.

Lamonema  barbntida,  Goode  and  Bean,  Bull.  Mus.  Comp.  Zool.,  x,  1883,  204. 

A  Lcemonema  having  head  contained  in  body  (without  caudal)  4~  times;  height  of  body 
4i  times.  Diameter  of  orbit  in  length  of  head  3  times,  upper  jaw  a  little  more  than  twice. 
Barbel  half  as  long  as  the  diameter  of  the  eye.  Vent  situated  under  the  sixth  or  seventh 
ray  of  second  dorsal.  Distance  of  first  dorsal  from  snout  equal  to  one-fourth  st  andard  length 
of  body.  The  base  of  the  first  dorsal  is  half  as  long  as  the  middle  caudal  rays;  that  of  the 
second,  slightly  more  than  3  times  the  length  of  the  head.  The  first  dorsal  is  composd  of  5 
rays,  the  first  of  which  is  elongate,  3  times  as  long  as  the  middle  caudal  rays;  it  extends  to 
the  base  of  the  twenty-fourth  ray  of  the  second  dorsal.  Anal  fin  inserted  at  a  distance  from 
the  tip  of  the  snout  equal  to  twice  the  length  of  the  head,  its  distance  from  the  insertion  of 
the  ventrals  being  equal  to  the  length  of  the  head.  The  length  of  the  ventrals  is  equal  to 
that  of  the  pectorals,  their  tips  not  extending  to  the  vent.

Color  .similar  to  that  of  the  various  species  of  Phycis;  the  dorsal  and  anal  fins  have  nar- 
row black  margins. 

The  length  of  the  first  dorsal  ray  is  very  variable  in  individuals,  being  slu  irter  in  younger 
specimens. 

This  species  differs  from  L.  Yarrellii  by  its  much  smaller  scales,  and  from  L.  robustum 
by  the  greater  number  of  rays  in  the  dorsal  and  anal  fins  and  its  much  shorter  ventrals.

The  Blake  obtained  examples  of  this  species  from  station  cccxxi,  in  32c  43'  25"  N.  Lit., 

77    20'  30"  W.  Ion.,  at  a  depth  of  233  fathoms;  from  station  CCCXV,  in  32     L8'  20"  N.   [at., 
78°  43   W.  Ion.,  at   a  depth  of  225  fathoms;  and  from  station  CCCXVI,  in  32°  7'  K  hit.,  78 
37'  30"  W.  Ion.,  at  a  depth  of  1-'l".i  fathoms.     A  single  specimen  was  also  obtained  by  the 
Fish  HawTc  on  October  10, 1881  (Cat.  No.  12904G,  TJ.  S.  H".  M.),  at  station  1045,  in  38°  35'  N. 
hit..  73°  13'  W.  Ion.,  at  a  depth  of  312  fathoms. 

L^MONEMA  MKLAXl'Rl'M,  Goode  and  Bean,  u.  s.     (Figure  316.) 

The  specimen  described,  catalogue  number  38270,  is  330  millimeters  in  length;  it  was 
obtained  by  the  steamer  Albatross  in  X.  hit.  30° 44'.  W.  Ion.,  79°  20'.  station  2415,  in  lid 
fathoms. 

The  greatest  depth  of  the  body  (1G5  millimeters)  is  contained  45}  times  in  the  length 
without  caudal.  The  length  of  the  head  (68  millimeters)  is  slightly  more  than  the  greatest 
height  of  the  body.  The  eye  is  very  large,  its  length  (25  millimeters)  about  one-third  the 
length  of  the  head  and  equal  to  twice  the  width  of  the  interorbital  space.  The  length  of 
the  snout  (18  millimeters)  is  about  one-fourth  the  length  of  the  head.  The  maxilla  ex- 
tends to  below  the  middle  of  the  eye.  The  length  of  the  intermaxilla  (36  millimeters)  is 
nearly  one-half  the  length  of  the  head.  The  length  of  the  mandible  (38  millimeters)  is  slightly 
more  than  twice  the  length  of  the  snout.  Teeth  in  the  intermaxilla  and  mandible  in  villi- 
form bands.  Vomerine  teeth  in  a  small  circular  patch  on  the  middle  of  the  head  of  the 
bone.  The  barbel  (17  millimeters)  is  about  as  long  as  the  snout.  The  distance  of  the  first 
dorsal  from  the  tip  of  the  snout  is  about  4  times  the  length  of  the  snout.  The  length  of 
the  first  ray  of  the  dorsal  (54  millimeters)  equals  that  of  the  head  without  the  snout:  the 
last  ray  is  scarcely  more  than  one-fourth  as  long  as  the  first. 

The  ventral  consists  of  a  single  bifid  ray;  its  distance  from  the  tip  of  the  snout  is 
equal  to  the  length  of  the  head;  its  length  (52  millimeters)  is  nearly  equal  to  that  of  the 
dorsal  and  the  pectoral  when  extended.  It  does  not  reach  the  vent  by  a  distance  equal  to 
the  length  of  the  snout.  The  length  of  the  pectoral  (54  millimeters)  equals  that  of  the 
longest  dorsal  ray.  and  also  equals  the  head  without  the  snout.  The  seconddorsal  is  higher 
anteriorly,  anil  posteriorly  much  higher,  than  it  is  in  the  middle;  the  longest  anterior  ray 
(26  millimeters)  is  one  half  the  length  of  the  ventral,  the  longest  posterior  ray  16 
millimeters)  being  one-half  the  length  of  the  head.  The  vent  is  under  the  eighth  my  of 
the  second  dorsal.  Gill-rakers  5+15;  the  longest  (4  millimeters)  one-fourth  as  long  as  the 
snout. 

Radial  formula:  D.6,57;  A.  55:  P.  25;  V.2;  Mr.  7:  Sc.  L6-160-38. 


3G4  DEEP-SEA   FISHES    OF    THE    ATLANTIC    BASIN. 

Color,  very  light  brown,  the  dorsals  and  anal  with  a  narrow  dark  margin.  A  conspicu- 
ous large,  triangular,  dark  blotch  on  the  last  rays  of  the  dorsal  and  anal,  and  a  dark  blotch 
occupying  almost  the  whole  of  the  caudal,  leaving  a  margin  of  whitish  around  it. 

In  addition  to  the  type,  specimens  of  this  species  were  obtained  by  the  Albatross  as

Gadus  raptor,  Nilsson,  Prodromus,  46. 

A  Molva  having  a  body  7  or  8  times  as  long  as  its  own  greatest  height,  and  5  times  as 
long  as  the  head.  Upper  jaw  the  longer,  the  maxillary  reaching  to  below  the  middle  of  the 
orbit.  Teeth  cardiform  in  the  jaws,  with  an  inner  row  of  rather  widely  separated  and  larger 
ones  in  the  mandible;  in  a  semicircular  band  on  the  vomer,  among  which  a  few  larger  ones 
are  interspersed.  The  first  dorsal  inserted  over  the  latter  half  of  the  pectoral,  its  greatest 
height  two-fifths  of  that  of  the  body  below  it.  Pectoral  about  half  as  long  as  the  head. 
Anal  insertion  in  vertical  over  seventh  or  eighth  ray  of  second  dorsal.  Barbel  longer 
than  eye,  the  diameter  of  the  eye  being  about  equal  to  the  width  of  the  iuterorbital  space. 
Scales  small,  covering  the  head,  body,  and  fins. 

Eadial  formula:  D.  13-10+03-70.  A.  57-06. 

Color,  back  gray,  lighter  on  the  sides  and  beneath;  vertical  tins  edged  with  white. 
A  dark  blotch  at  the  posterior  end  of  the  first  dorsal,  and  a  more  distinct  one  on  the  end 
of  the  second  dorsal. 

This  fish,  the  "Ling"  of  Europe,  is  found  from  Spitzbergen  to  the  Gulf  of  Gascony, 
where  specimens  have  been  taken  very  exceptionally  at  Arcachon  and  San  Juan  de  Luz. 
It  is  very  rare,  however,  south  of  the  British  Channel,  and  most  abundant  along  the  coast 
of  Northern  Europe  and  about  Iceland,  especially  in  the  German  Ocean  and  off  Norway. 
It  is  rare  about  Iceland,  Greenland,  and  the  Faroe  Islands,  and  has  never  been  found  in  the 
Baltic.  It  is  said  to  have  been  found  in  the  deep  water  oft'  Newfoundland,  but  we  have 
been  unable  to  find  the  specific  record.  Collett  states  that  on  the  Norwegian  coast  young- 
examples  rarely  occur  at  less  depth  than  100  fathoms,  and  according  to  Lilljeborg  the 
largest  are  caught  in  from  80  to  150  fathoms.

A  Molva  characterized  by  the  length  of  the  pectoral  fin,  which  extends  further  back- 
ward than  the  ventral,  while  the  anal  extends  further  backward  than  the  dorsal;  also  by 
the  comparative  shortness  of  the  first  dorsal  fin.  The  lower  jaw  is  longer  than  the  upper 
one.  The  length  of  the  barbel  is  not  quite  half  the  width  of  the  interorbital  space.  The 
anal  is  inserted  behind  the  vertical  from  the  origin  of  the  second  dorsal.  The  first  three 
rays  of  the  ventral  are  elongated. 

Radial  formula:    D.  10-11+77-81:    A.  73-78. 

Color  above,  ashy;  below,  silvery  white.  The  dorsal  and  caudal  are  margined  with 
black;  white  at  the  edge.  The  second  dorsal  has  on  its  posterior  rays  a  very  black  spot. 
The  caudal  is  black  at  its  lower  posterior  angle. 

This  form  is  found  only  in  the  Mediterranean,  and  is  very  common  at  Nice.  It  occurs 
off  the  west  coast  of  Italy,  though  it  is  not  abundant.  Giglioli  also  records  it  from  Mes- 
sina, where  it  is  rare.

outer  ones  filamentous.  Anal  not  notched.  Caudal  rounded,  slender,  tree.  A  barbel  upon 
the  chin.     Branchiostegals  7.     (iill  rakers  of  the  outer  branchial  arch  short. 

Giinther,  in  his  report  on  the  deep  sea  fishes  of  the  Challenger,  combines  his  genus,  the 
Pseudophycis,  with  I'hysiculus,  stating  that  in  consequence  of  the  discovery  of  several  in- 
termediate forms,  a  generic  distinction  between  them  cannot  be .maintained ;  and  furthei 
that  most  probably  the  transition  from  the  perfectly  developed  many-rayed  tin  tothesingle 
filament  of  Phycis,  will  be  found  to  lie  so  gradual  as  to  diminish  the  value  of  the  structure 
of  this  lin  as  a  taxonomie  character  in  this  group. 

In  addition  In  the  four  species  described  below,  two  other  species  have  been  described —

Giinther  has  studied  3  specimens  from  Madeira,  the  largest  10  inches  long,  and  notes 
that  all  have  an  exceedingly  narrow  base  to  the  ventral  fin. 

The  species  is  only  known  from  Madeira  and  from  off  Soudan,  where  the  Talisman  ob- 
tained it  at  two  stations,  lxii,  7S2  meters,  and  lxxi,  640  meters.

"This  species,"  writes  Gunther,  "has  constantly  (as  far  as  is  shown  by  our  specimens) 
a  broader  base  to  the  ventral  tins  than  Physiculus  dalwiglcii,  and  they  are  formed  of  7  rays,  of 
which  the  longest  may  or  may  not  reach  the  anal  tin.  The  fin  rays  vary  within  proportion- 
ate limits;  they  are:  1).  9-10  |  60-66;  A.  60-70.  There  are  13  series  of  scales  between  the 
anterior  dorsal  and  the  lateral  line.  The  peduncle  of  the  tail  is  shorter  and  less  slender  than 
in  the  Madeiran  form,  but  otherwise  the  two  species  are  so  similar  as  to  scarcely  deserve 
specific  separation." 

Poey  obtained  a  specimen  at  Cuba,  and  Melliss  two  at  St.  Helena.  These  are  pro- 
nounced by  Giinther  to  differ  in  no  respect  from  five  examples  found  by  the  Challenger  off 
Inosima  iu  343  fathoms,  and  11  to  16  inches  long.

Physiculus  peregrinus,  Gi  nthkr,  Challenger  Report,  xxn,  1887,  88. 

The  height  of  the  body  is  less  than  the  length  of  the  head,  which  is  two-ninths  of  the 
total  (without  caudal).  Vent  at  only  a  short  distance  behind  the  base  of  the  pectoral ;  tail 
tapering  into  a  very  narrow  band,  the  extremity  of  which  is  surrounded  by  the  caudal  fin; 
however,  the  vertical  fins  remain  separate  from  one  another.  Head  rather  broader  than 
deep,  its  greatest  width  being  two-thirds  of  its  length.  Interorbital  space  concave,  its  width 
being  less  than  the  diameter  of  the  eye,  which  is  one-fourth  of  the  length  of  the  head,  and 
equals  that  of  the  snout.  Snout  broad,  obtuse,  rounded,  with  the  upper  jaw  overlapping 
the  lower;  the  maxillary  extends  to  below  the  middle  of  the  eye.  Barbel  shorter  than  the 
eye.  Vertical  fins  of  moderate  depth,  with  very  fine  fin-rays;  the  first  dorsal  commences 
opposite  to  the  base  of  the  pectoral.  Pectoral  as  long  as  the  head  without  snout.  The 
ventral  filament  is  jugular,  extending  beyond  the  origin  of  the  anal,  and  composed  of  one 
longer  and  two  shorter  rays.     Scales  minute  and  deciduous. 

Radial  formula:  D.  7  +  iil!  (ca.);  A.  66  (ca.);  V.  3. 

Color  reddish  olive  (iu  spirits),  abdomen  black. 

The  British  Museum  has  several  examples  of  this  species  from  Manado,  one  of  which 
measures  5  inches  iu  length. 

Another  species,  P.  palmatus,  Kliinzmger,  is  from  Port  Philip,  Hobson  Bay — probably 
not  a  deep-sea  form.

Physiculus  f ulvus,  BEAN,  Proc.  U.  S.  Nat.  Mus.,  1884,  vn,  240. 

A  Physiculus  with  head  broad  and  depressed,  with  a  short  snout;  the  length  of  the 
head  contained  in  the  total  length  to  the  caudal  base  nearly  4  times.  The  height  of  the 
body  is  about  equal  to  the  length  of  the  head  without  the  snout,  and  is  contained  4ij  times 
in  the  total  length  without  caudal.    The  eye  is  about  two-sevenths  as  long  as  the  head. 


DISCUSSION   OF   SPEC IKs    AM)   TIIKIK    DISTRIBUTION.  307 

The  length  of  the  upper  jawis  about  equal  to  the  space  between  the  ventrals  and  the  anal 
origin,  and  is  contained  2|  times  in  that  of  the  head.  The  maxilla  docs  not  quite  reach  the 
vertical  through  the  hind  margin  of  the  eye.    The  barbel  is  one-sixth  as  long  as  the  head. 

The  teeth  are  in  narrow  bands  in  the  jaws;  there  is  no  outer  series  of  enlarged  teeth,  but  a 
tew  in  the  middle  Of  the  bands  in  both  jaws  are  slightly  larger  than  the  others;  all  of  the 
teeth,  however,  are  inconspicuous;  the  vomer  and  palate  are  smooth.  The  vent  is  situated 
about  under  the  third  ray  of  the  firs!  dorsal.  The  distance  of  the  lirst  dorsal  from  the  tip  of 
the  snout  equals  3  times  the  length  of  its  base;  its  longest  ray  equals  twice  the  length  of 
the  snout,  and  slightly  exceeds  the  length  of  the  longest  of  the  second  dorsal;  the  length  of 
the  second  dorsal  base  equals  ."»  times  the  length  of  the  pectoral,  which  is  contained  nearly 
54  times  in  the  total  without  caudal.  The  origin  of  the  anal  is  about  in  a  vertical  let  fall 
from  the  base  of  the  fifth  ray  of  the  lirst  dorsal.  The  distance  of  the  ventral  from  the  tip 
of  the  snout  is  contained  about  5|  times  in  the  standard  body-length.  When  the  Neutral  is 
extended  backward  its  tip  will  reach  the  base  of  the  fourth  anal  ray.  The  length  of  the 
middle  caudal  ray  is  one-third  of  the  length  of  the  head.  The  lateral  line  is  very  indis- 
tinct, but  it  is  situated  rather  high,  and  folli  ws  pretty  closely  the  contour  of  the  back. 
The  gill  rakers  are  moderately  short  and  not  numerous. 

Radial  formula:  D.  10+49;  A.  54;  V.  7;  scales  0-01  to  <i2-lG. 

The  general  color  is  a  light  yellowish-brown  with  the  under  surface  of  the  head,  the 
abdomen,  the  margins  of  the  dorsal  and  anal  fins,  the  lips,  and  the  axil  of  the  pectoral 
\  c  iv  dark  brown.  There  is,  also,  a  dark  brown  blotch  on  the  suboperculum.  The  inside 
of  the  mouth  and  of  the  gill-membranes  is  white. 

The  type  of  this  species  (Cat,  No.  287(16,  U.  S.  N.  M.)  was  taken  by  the  Fish  Hawk 
from  station  941,  in  40°  1'  X.  hit,,  69°  50'  W.  Ion.,  at  a  depth  of  7!)  fathoms.  Specimens 
were  also  obtained  by  the  Blake  at  station  ccxxxvm,  in  24°  36'  1ST.  hit,,  84°  5'  W.  Ion.,  at

The  head  is  rather  thick,  its  greatest  width  being  equal  to  its  height,  which  is  somewhat 
more  than  one-half  of  its  length;  its  length  is  one  fourth  of  the  total  (without  caudal).  The 
cleft  of  the  mouth  is  oblique,  wide,  the  maxillary  extending  to  below  the  posterior  margin 
of  the  orbit.  The  lower  jaw  is  received  within  the  upper,  but  both  are  nearly  equal  in  length 
anteriorly;  they  are  armed  with  a  series  of  rather  large,  curved,  widely  set  teeth,  and  there 
is  another  series  of  small  teeth  within  the  outer  in  the  upper  jaw.  Snout  rather  broad, 
obtusely  rounded,  scarcely  longer  than  the  eye,  the  diameter  of  which  is  two-ninths  of  the 
length  of  the  head.  The  interorbital  space  is  emarginate  on  each  side  by  the  upper  part  of 
the  orbit,  and  its  width  is  somewhat  more  than  the  diameter  of  the  eye.     Nape  of  the  neck

broad,  scarcely  elevated,  with  a  spine  on  each  side  pointing  outwards  and  covered  by  skin. 
Operculum  small,  with  a  slender  horizontal  spine  posteriorly,  the  part  below  the  spine  being 
emarginate.  Gill-membranes  united  below  the  throat  by  a  rather  narrow  cutaneous  bridge, 
not  attached  to  the  isthmus.  Gill-opening  wide;  gills  4,  a  slit  behind  the  fourth;  pseudo- 
branchiae  glandular.  The  trunk  is  rather  low,  its  greatest  depth  being  one-sixth  of  the  total 
(without  caudal).  Tail  tapering  into  a  very  narrow  band.  The  first  dorsal  fin  commences 
behind  the  vertical  from  the  base  of  the  pectoral,  is  somewhat  higher  than  long,  and  not 
higher  than  the  second.  The  second  dorsal  commences  immediately  behind  the  first;  its 
rays  increase  somewhat  in  length  posteriorly,  one  of  the  longest  being  half  as  long  as  the 
head.  The  whole  fin  is  naked.  Caudal  fin  slender,  slightly  rounded,  entirely  free  from 
dorsal  and  anal,  and  nearly  half  as  long  as  the  head.  The  anal  fin  commences  at  some 
distance  behind  the  vent,  which  is  situated  vertically  below  the  origin  of  the  first  dorsal; 
it  is  very  similar  to  the  second  dorsal.  The  pectoral  is  inserted  somewhat  below  the  middle 
of  the  body,  and  its  length  equals  the  distance  between  the  front  margin  of  the  eye  and 
the  end  of  the  operculum.  Ventrals  narrow,  slender,  with  the  outer  ray  produced  into  a 
filament  shorter  than  the  pectoral. 

The  scales  extend  over  the  whole  head,  the  chin  and  the  thin  lips  being  naked.   (Giinther.) 
This  form,  originally  described  from  Nice,  has  since  been  found  at  Madeira  by  John- 
son, and  at  Naples  and  Catania  by  Giglioli. 

The  Blalce  obtained  a  poor  specimen,  apparently  of  this  form,  at  station  LXXXi,  oil"  the 
Island  of  Nevis,  in  the  West  Indies.

with  a  barbel.    Branchiostegals  7  (<»?).     (GUnthcr.) 

Five  species  of  this  genus  are  known:  L.  j>hycis  (Schlegel),  Giinther,  from  Japan;  L. 
rhachinus  (Forster)  Giinther,  from  Queen  Charlottes  Sound;  1j.  fuliginosa,  described  by 
Giinther  from  a  specimen  without  locality  in  the  British  Museum;  L.  mawillaris,  Bean, 
doubtfully  referred  tu  this  genus,  and  L.  marginata,  Giinther,  from  140-345  fathoms,  off 
the  Pacific  Coast  of  southwestern  South  America.

A  Lotella  having  the  length  of  its  moderately  compressed  head  contained  about  4£  times 
in  the  total  length  without  caudal;  the  height  of  the  body  5  times.  Snout  short.  The  eye 
is  one  third  as  long  as  the  head.  The  maxilla  reaches  to  the  vertical  through  the  anterior 
margin  of  the  pupil;  its  length  equals  that  of  the  postorbital  part  of  the  head.  The  teeth 
are  in  narrow  bands  in  the  jaws,  the  outer  series  being  enlarged.  The  vomer  and  palate 
seem  to  be  without  teeth.  The  vent  is  situated  about  under  the  eighth  ray  of  the  second 
dorsal.  The  distance  of  the  first  dorsal  from  the  tip  of  the  snout  is  contained  4  times  in  the 
total  length,  including  caudal.  The  ventrals  extend  to  about  the  vertical  from  the  origin 
of  the  second  dorsal,  and  do  not  reach  nearly  to  the  vent.  The  longest  ray  of  the  first 
dorsal  is  a  little  more  than  one-half  as  long  as  the  head.  None  of  the  rays  of  the  second  or 
of  the  anal  are  as  long  as  the  first  ray  of  the  first  dorsal.  The  longest  ray  of  the  second 
dorsal  does  not  much  exceed  one  half  the  height  of  the  body.  The  longest  ray  of  the  anal 
is  about  one-half  the  length  of  the  ventral.  The  origin  of  the  anal  is  about  under  the  tenth 
ray  of  the  second  dorsal.  The  ventrals  are  situated  about  under  the  beginning  of  the  pos- 
terior third  of  the  head;  their  length  equals  one-fourth  of  the  length  of  the  second  dorsal 
base.    The  origin  of  the  pectoral  is  somewhat  in  advance  of  that  of  the  first  dorsal.    The

Owing  t<>  the  condition  of  the  specimen  it  is  very  difficult  to  counl  the  small  scales,  bul 
there  are  about  7  or  8  rows  between  the  origin  of  the  lir-t  dorsal  and  the  lateral  line,  and 
about  11  or  15  rows  between  the  anal  and  the  lateral  line.  The  number  in  the  lateral  line 
is  at  least   L15  to  the  origin  of  the  caudal. 

The  color  of  the  type  at  present  is  a  very  light  brown.  The  margins  of  the  dorsal  and 
anal,  in  their  posterior  portions,  are  blackish.

A  Mora  having  the  upper  jaw  longer  than  the  lower,  and  a  slender  barbel,  whose 
length  is  less  than  that  of  the  diameter  of  the  eye.    Caudal  forked.     First  ventral  ray  pro 
longed  in  a  slender  thread,  which  reaches  behind  the  tip  of  the  pectoral.     Scales  small,  95 
in  the  lateral  line.

Color  chestnut  brown  upon  the  hack,  dark  ash  color  on  the  belly,  a  blue  spot  upon  the 
tip  of  the  operculum.  The  palate  and  tongue  are  dark  blue,  the  hitter  with  black  spots. 
Dorsal  and  anal  light  blue  at  the  base,  darker  at  the  tip.    Pectorals  light  blue  with  black

This  species,  the  Mora  of  Nice  and  the  Verdone  of  Borne,  was  first  found  in  the  Med- 
iterranean, where  it  has  been  recorded  from  Nice,  Genoa  and  Leghorn.  Risso  said  of  it  in 
1S10  that  it  was  very  common  in  great  depths  of  the  sea  oil'  Nice,  where  it  is  taken  in  the 
month  of  August.  Giglioli,  fishing  at  Genoa,  July  26,  1*79,  at  a  depth  of  800  to  1,000 
meters,  captured  ninety-seven.  It  has  not  been  found  in  the  Adriatic,  but  Brito  Capello 
records  it  from  oil' the  coast  of  Portugal,  and  Lowe,  also  from  300  to  -100  fathoms  nil  Mag- 
dalen, i,  5  leagues  to  the  west  of  Funchal,  while  Webb  and  Berthelol  obtained  it  at  the  Ca- 
naries. The  Talisman  took  it  at  the  same  region  (station  L)  at  975  meters,  as  well  as  oil 
Morocco  (stations  ix,  xi,  xxxiv,  Xlvii,  xj.viii)  at  depths  of  from  622  to  1,180  meters.  The 
Travailleur  obtained  it  at  Setubal  (stations  xxxiv  and  xxxv)  in  1,307  meters,  and  in  the 
Gulf  of  Gascony  in  614  meters.  The  Challenger  obtained  specimens  also,  but  they  wen 
destroyed  on  shipboard  and  the  record  of  locality  lost.  It  has  never  been  found  in  the 
Western  Atlantic.

A  Lepidion  having  a  broad,  thick,  flat  head,  covered  with  scales,  and  with  an 
occipital  keel.  The  length  of  the  head  contained  4.1  times  in  the  total  length  of  the  fish. 
Snout  depressed,  short,  obtuse.  Mouth  broad,  its  angle  under  the  anterior  portion  of  the 
orbit.  Upper  jaw  broad,  longer  than  the  mandible.  Teeth  small,  cardiform,  on  the  jaws 
and  vomer.  Eye  large,  round,  its  diameter  contained  3£  times  in  the  length  of  the  head, 
and  nearly  equal  to  the  length  of  the  snout.  Tip  of  maxillary  extending  beyond  vertical 
from  the  middle  of  the  orbit.  Scales  very  small,  from  155  to  100  in  the  lateral  line,  and 
about  11  longitudinal  rows  bet  ween  the  first  dorsal  and  the  lateral  line,  which  is  a  little  curved 
anteriorly,  but  straight  after  it  passes  the  vertical  from  the  origin  of  the  anal.  The  first 
dorsal  placed  far  forward,  in  vertical  from  the  insertion  of  the  pectorals;  it  is  composed  of 
only  4  rays,  the  first  of  which  is  much  prolonged;  its  length  two  fifths  the  total  length  of 
the  fish.  The  second  dorsal  with  a  very  long  base.  The  median  rays  of  the  anal  are  much 
shorter  than  the  others,  giving  it  a  cresecntie  emarginate  outline.  Caudal  long,  rounded. 
Ventrals  very  long,  their  tips  reaching  the  anus,  but  rarely  extending  beyond  those  of  the 
pectoral  rays.

Color,  grayish-brown  with  a  reddish  tint.  The  second  dorsal  blue,  edged  with  black; 
the  other  fins  more  or  less  brown  in  alcoholic  specimens.  The  caudal  and  anal  blackish, 
as  are  the  opercles. 

This  species,  originally  described  from  Nice  in  1810,  was  said  by  Risso  to  be  very  rare, 
and  only  taken  at  considerable  depths  in  the  month  of  August.  It  has  never  been  seen 
elsewhere  than  at  Nice,  where  Giglioli  obtained  specimens  in  September,  1870. 

The  Madeiran  form  identified  with  this  by  Giinther  before  he  had  had  the  opportunity 
of  examining  a  specimen,  has  since  been  determined  to  be  distinct,  and  was  renamed  by 
Gignoli,  Haloporphyrm  Gimtheri.

*  According  to  Dr.  Giinther  (v.  4,  p.  358),  "the  generic  name  Lepidion  is  preoccupied,"  but  it  is  not  stated 
in  what  way.  When  it  is  remembered  that  Dactylopus  was  said  to  lie  preoccupied  because  Meyer  had  named 
a  group  of  extinct  reptiles  Dactylopoda.  It  will  he  understood  why  as  no  record  of  an  earlier  use  of  Lepidion 
than  1838  appears  in  the  nomenclators,  we  must  adopt  it  till  further  information  is  given  as  to  the  nature  of 
the  supposed  preoccupation.  Savigny  had  given  the  name  Lepidia  to  a  genus  of  worms  in  1817,  and  Lepelletier 
had  named  Lepisia  a  genus  of  beetles  in  1825,  but  those  are  sufficiently  distinct  from  the  Swainsouiau  name.

The  diameter  of  the  eye  is  one-sixth  the  length  of  the  head  (in  specimens  20  to  2  I  inches 
long).  Caudal  peduncle  rather  slender,  its  depth  being  i  wo  thirds  of  the  distance  between 
dorsal  and  caudal  fins.  Fifteen  or  10  longitudinal  scries  of  scales  between  the  anterior  dor- 
sal (in  and  the  lateral  line,  and  210  in  the  lateral  line.  The  dorsal  lilameut  very  thin,  thread- 
like.    (Giinther.)

The  length  of  the  head  equals  the  distance  between  the  root  of  the  ventral  tin  and  the 
anal,  and  is  rather  less  than  one-fourth  of  the  total  (without  caudal).  The  eye  is  very  large, 
one-third  of  the  length  of  the  head,  longer  than  the  snout,  and  nearly  twice  the  width  of  the 
intcrorbital  space.  Snout  of  moderate  length,  obtuse,  with  an  undulated  series  of  pores  in 
the  preorbital  region  running  toward  the  extremity  of  the  snout.  The  mouth  extends 
nearly  to  below  the  middle  of  the  eye.  Barbel  half  the  length  of  the  eye.  The  caudal 
peduncle  very  slender,  its  depth  being  two-fifths  of  the  distance  between  dorsal  ami  caudal 
iius.  Fifteen  or  16  longitudinal  series  of  scales  between  the  anterior  dorsal  tin  and  the  lat- 
eral line  and  180  in  the  lateral  line.  The  first  long  dorsal  ray  is  compressed,  moderately 
strong,  extending  backward  to  the  posterior  fourth  of  the  length  of  the  dorsal  fin.  The 
middle  of  the  anal  fin  very  conspicuously  depressed.  Caudal  fin  rounded,  with  its  basal 
rays  extending  for  some  distance  along  the  peduncle.  Pectoral  fin  as  long  as  the  head  with- 
out snout.  The  filamentous  ventral  ray,  which,  in  fact,  consists  of  two  rays,  free  along  their 
distal  half,  does  not  exceed  in  length  the  pectoral  fin.     Caec.  pyl.  10-11. 

Eadial  formula:  D.  4+56-62;  A.  49-54;  V.  7;  L.  lat.  180. 

Color,  brownish  with  blackish  fins;  orbitwitha  black  ring;  the  cavities  of  the  mouth, 
gills,  and  abdomen  black.  Specimens  of  a  much  lighter  color  (probably  albinos)  are  not 
scarce.     (Giinther.) 

Young  specimens  (0  inches  in  length),  says  Giinther,  do  not  differ  essentially  from  older 
ones  of  twice  the  length,  but  their  eye  is  relatively  still  larger  and  the  dorsal  filament  some- 
what smaller.  Numerous  specimens  were  obtained  by  the  Knight  Errant,  in  the  Faroe 
Channel,  in  530  fathoms,  the  largest  being  12  or  13  inches  long,  at  station  6,  in  August, 
1880,  and  station  2,  in  August,  1882. 

Giinther  formerly  believed  that  these  specimens  represented  the  younger  stage  of 
the  large  specimen  from  Madeira  (the  oidy  one  known  to  him  at  the  time)  which  he  referred 
in  1862  to  Bisso'sfish;  but  examples  received  at  a  later  period  convinced  him  that  the 
present  species  may  be  constantly,  at  all  ages,  distinguished  by  a  comparatively  larger  eye 
and  shorter  head.  However,  the  three  European  species,  viz,  Lcpidion  Giientheri,  Lepi- 
dion  liissoi,  and  Lepidion  eques  are  most  closely  allied  to  each  other.

Distinguished  by  the  very  broad  and  compressed  dorsal  ray.  The  length  of  the  head 
equals  the  distance  between  the  root  of  the  ventrals  and  the  vent.  Eye  rather  large,  two- 
sevenths  of  the  length  of  the  head,  a  little  longer  than  the  snout,  and  in  width  much  ex- 
ceeding the  intcrorbital  space;  pores  of  the  preorbital  region  very  small.  Mouth  compara- 
tively narrow,  only  reaching  beyond  the  anterior  margin  of  the  eye;  barbel  much  shorter 
than  the  eye.  Caudal  peduncle  rather  slender,  its  depth  being  rather  more  than  one-half 
the  distance  between  dorsal  and  caudal  fins.  Scales  very  small,  rather  irregularly  arranged; 
about  18  longitudinal  series  between  rhe  firs!  dorsal  fin  and  the  lateral  line.  The  long  dor- 
sal ray  is  strongly  compressed,  broad,  shaped  like  a  blade  of  grass,  ami  extending  backward 
to  the  posterior  third  of  the  dorsal  fin.    It  is  so  in  3  male  specimens,  but  in  a  female  the

ray  is  much  less  developed,  scarcely  extending  beyond  the  anterior  third  of  the  dorsal  fin. 
Middle  of  the  anal  fin  strongly  depressed;  caudal  fin  subtruncated;  pectoral  as  long  as  the 
head  without  snout,  much  shorter  than  tbe  filamentous  ventral  fin,  which,  however,  does 
not  reach  the  vent.     (Giinther.)

This  species  was  obtained  by  the  Challenger,  at  station  320,  off  the  mouth  of  the  La  Plata, 
and  is  described  and  figured  by  Giinther  (Challenger  Report,  xxn,  18S7,  92,  pi.  xix,  fig.  A).

Antimora  viola,  Jordan,  Cat.  Fish.  N.  Amer.,  129.— GCnther,  Challenger  Report,  xxn,  1887,  94,  pi.  xv. 

An  Antimora  with  body  resembling  that  of  Phycis,  though  somewhat  shorter,  higher, 
and  more  compressed,  its  greatest  height  contained  about  five  times  in  its  length  (without 
caudal),  its  height  at  the  ventrals  slightly  exceeding  one-eighth  of  its  total  length,  its  height 
at  the  middle  of  the  caudal  peduncle  one  twenty-ninth  of  the  same. 

Scales  arranged  in  about  115  vertical  rows  and  about  38  horizontal  ones,  about  11  being 
between  the  origin  of  the  dorsal  and  the  lateral  line  and  about  27  below  the  lateral  line. 
Lateral  line  slightly  curved  upward  in  the  anterior  fourth  of  its  length. 

Length  of  head  contained  more  than  four  and  one-quarter  times  in  that  of  the  body; 
its  width  half  its  length  and  less  than  double  that  of  interorbital  area. 

The  barbel  is  short,  its  length  being  scarcely  equal  to  half  the  diameter  of  the  orbit  and 
about  one-tenth  the  length  of  the  head.  The  width  of  interorbital  area  is  about  equal  to 
the  longitudinal  diameter  of  the  orbit,  in  the  larger  specimen  slightly  greater.  The  diameter 
of  the  orbit  is  equal  to  or  slightly  greater  than  one-fourth  the  length  of  the  head.  The  length 
of  the  snout  is  equal  to  that  of  the  operculum  and  less  than  width  of  interorbital  area. 

The  maxillary  extends  to  vertical  from  posterior  margin  of  the  orbit,  its  length  about 
equal  to  the  greatest  width  of  the  head.  Mandible  equals  one  eighth  of  total  length  with- 
out caudal. 

Snout  equal  to  operculum  in  length,  obtusely  pointed,  much  depressed,  its  lateral  out- 
line subcorneal,  a  conspicuous  keel  extending  backward  along  the  lower  line  of  the  orbit  to 
its  posterior  margin.  The  head  and  mouth  closely  resemble  those  of  some  species  of  Macru- 
rus,  except  that  the  keel  is  covered  with  small,  smooth  scales  and  is  not  overhanging.  Lips 
scaleless. 

Teeth  in  the  jaws  imperfectly  serial,  villiform,  recurved;  a  small  oblong  patch  of  similar 
teeth  on  the  head  of  the  vomer;  none  on  the  palatines. 

First  dorsal  fin  inserted  at  a  distance  from  the  snout  somewhat  greater  than  twice  the 
height  of  the  body  at  the  ventrals;  its  first  ray  is  much  prolonged,  its  length  greater  than 
that  of  the  head,  and  nearly  as  long  as  or  longer  (in  the  larger  specimen)  than  the  distance 
from  the  snout  to  the  beginning  of  the  dorsal.  The  second  ray  is  contained  less  than  four 
times,  the  third  six  times  or  less  in  the  first,  the  fourth  about  ten  times.  The  length  of  the 
base  of  second  dorsal  is  somewhat  more  than  twice  the  distance  of  its  insertion  from  the

snout;  its  greatest  height,  which  is  in  the  posterior  fourth  of  its  length  (near  the  40th  ray), 
is  contained  about  six  or  seven  times  in  the  length  of  its  base. 

Tin-  vent  is  situated  at  a  point  equidistant  from  snout  and  tip  of  caudal,  under  the  19th 

ray  of  second  dorsal  tin.     The  anal  tin  is  inserted  at  a  distance  behind  it  equal  to  length  of 

second  anal  ray.     Its  length  of  base  is  slightly  more  than  half  that  of  sec 1  dorsal.     It 

has  a  considerable  depression  in  its  middle  outline.  The  last  lays  of  dorsal  and  anal  are  of 
equal  length  and  are  directly  opposite  each  other. 

'fhe  caudal  seems  to  be  somewhat  rounded.  The  length  of  the  middle  rays  contained 
more  than  !l  times  in  total  length  without  caudal,  and  more  than  10  times  in  length  includ- 
ing caudal. 

Pectorals  narrow,  inserted  under  the  base  of  fust  dorsal.  In  the  smaller  specimen  they 
reach  to  the  perpendicular  from  the  ninth  ray  of  the  second  dorsal,  in  length  equaling  the 
greatest  height  of  the  body. 

Ventrals  inserted  at  a  distance  from  tip  of  snout  equal  to  half  the  length  of  anal  base; 
the  second  ray  nearly  twice  as  long  as  the  first,  and  in  the  smaller  speeimeu,  in  which  it  is 
unmutilated,  nearly  as  long  as  the  head.

The  types  of  this  species  were  brought  into  Gloucester  August  24, 1 878,  by  Capt.  Joseph 
W.  Collins,  the  skipper  of  the  schooner  Marion  of  Gloucester,  having  beeu  taken  ou  a

ANTTMOR  V  ROSTRATA,  Gt  nther. 

Intimora  roslrata,  GOnther,  Ann.  and  Mag.  Nat.   Hist.,  n.  1878,  L8;  Challenger  Report,  sxn,  '.887,  92,  p] 
xvi,  fig.  A. 

This  species  is  readily  distinguished  by  the  peculiarly  produced  s t.  which  forms  a 

short,  triangular,  pointed  lamina,  sharply  keeled  on  the  sides,  and  overhanging  the  cleft 
of  the  mouth. 

The  head  is  rather  short,  broad  posteriorly,  half  as  long  as  the  distance  between  ventral 
and  anal  tins.  Bye  round,  rather  large,  its  diameter  one-fourth  of  the  length  of  the  head, 
less  than  that  of  the  snout,  and  nearly  equal  to  the  width  of  the  Hat  interorbital  space. 
Mouth  wide-,  the  maxillary  extending  nearly  to  belo^  the  hind  margin  of  the  eye.  Teeth 
in  both  jaws  in  narrow  villifonn  hands;  a  small  group  of  teeth  on  the  vomer.  Posterior 
extremity  of  the  maxillary  not  much  dilated.  Nostrils  dose  together;  the  posterior  are 
wide  semicircular  openings,  the  anterior  narrower  and  round.  The  vent  is  rather  nearer 
to  the  end  of  the  operculum  t  han  to  the  root  of  the  caudal. 

The  entire  head  (even  the  gill  membrane  and  the  foremost  part  of  the  snout)  and  the 
body  are  covered  with  small  cycloid  scales,  of  which  only  a  few  have  been  preserved :  there 
are  about  10  in  a  transverse  line  between  the  first  dorsal  tin  and  the  lateral  line  and  140  in 
the  lateral  line. 

The  greater  part  of  the  dorsal  and  anal  tins  are  covered  with  scales.  The  first  dorsal 
is  subcontinuous  with  the  second,  and  the  firs!  ray  is  produced  into  a  filament  about  as 
long  as  the  head.  The  second  dorsal  and  anal  fins  are  rather  low7;  the  latter  so  much 
depressed  in  the  middle  as  to  present  the  appearance  of  a  double  anal.  The  free  portion 
of  the  tail  is  narrow,  terminating  in  a  comparatively  small  caudal  fin,  which  is  truncated 
behind.  Pectoral  pointed,  the  upper  rays  being  the  longest;  it  is  as  long  as  or  longer  than 
the  head  exclusive  of  the  snout.  The  two  outer  ventral  rays  prolonged  as  two  filaments; 
the  second  being  twice  as  long  as  the  first,  and  not  extending  as  far  back  as  the  pectoral. 

Radial  formula:  D.  4,  51-50;  A.  38-39;  Y.  0. 

Color,  black:  the  cavity  of  the  mouth,  gills  and  abdomen  deep  black. 

This  form  occurs  midway  between  the  Cape  of  Good  Hope  and  Kergnelen  Island,  and 
also  east  of  the  mouth  of  the  Rio  de  la  Plata.  The  Challenger  obtained  a  specimen,  12A 
inches  long,  at  station  140,  near  Marion  Island  in  1,375  fathoms;  and  a  specimen  2A  inches 
long,  at  station  320,  off  Montevideo,  in  600  fathoms. 

HALARGYREUS,  Guuther. 

Balargyrem,  GOnther,  Cat.  Fish,  Brit.  Has.,  iv,  1862,  312.     (type,  //".  Johnsonii,  Gtlnther.) 

Body  elongate,  covered  with  small  scales  (a  separate  caudal):  L'  dorsal  and  2  anal 
tins,  the  latter  subcontinuous:  ventrals  composed  of  several  rays,  .laws  with  a  baud  of 
minute  villifonn  teeth  of  equal  size;  no  teeth  on  the  vomer  or  palatine  bones.  No  barbel. 
Branchiostegals 7.  Pseudobranchise  glandular,  rudimentary,  covered  by  tin-  membrane; 
gill  rakers  of  the  outer  branchial  arch  long,     ((liuilhcr.) 

HALARGYREUS  BREVIPES,   Vaili.ant.     (Fig.  325.) 

Balargyreus  brevipes,  Yaii.i.ant.  Exp.  Sci.  Travailleur  el   Talisman,  xxn,  1888,  295,  pi.   xxv,  tig.  5. 

A  Halargyreus  having  (according  to  Vaillant),  a  general  resemblance  to  Merlucius  smi- 

ridux,  body  being  nearly  cylindrical  anteriorly,  and  its  thickness  nearly  equal  to  its 
greatest  height,  which  is  one  eighth  of  its  length.  The  length  of  the  head  is  one  fourth  the 
length  of  the  body,  and  its  width  is  a  little  less  t  han  its  height.  Snout  moderate,  its  length 
about  one  third  that  of  the  head.  Mouth  rather  large,  although  the  maxillary  does  not 
extend  beyond  the  vertical  from  thi'  center  of  the  orbit.     Lower  jaw  slightly  longer  than 


376  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

the  upper  one.  Jaws  covered  with  flue  teeth  in  bands;  vomer  and  palatines  toothless. 
Diameter  of  the  eye  one-fourth  the  length  of  the  head;  interorbital  space  much  less,  about 
two-elevenths  of  the  length  of  the  head.  No  barbel.  Vent  nearly  median.  Scales  small, 
about  122  (as  nearly  as  could  be  ascertained  by  Vaillant)  in  the  lateral  line;  seven  above  and 
thirty  below.     The  lateral  line  is  near  the  dorsal  outline. 

First  dorsal  inserted  behind  the  vertical  from  the  base  of  the  pectorals  and  short;  the 
second  placed  close  to  the  first,  and  extending  almost  to  the  base  of  the  foremost  rays  of 
the  caudal.  First  anal  under  the  vertical  from  the  fourteenth  to  the  sixteenth  ray  of  the 
second  dorsal,  terminating  nearly  under  the  tenth  from  the  last  ray  of  the  same  flu.  The 
anal  is  deeply  notched,  its  twenty-seventh  ray  being  longer  than  any  of  the  preceding  ones, 
while  the  twenty-sixth  is  very  short.  The  form  of  these  two  fins  is  best  expressed  by  the 
accompanying  illustration.     Pectorals  moderate,  ventrals  exceedingly  short. 

Eadial  formula:  D.  8+56;  A.  2G+22;  V.  5. 

Color  reddish-brown ;  silvery  upon  the  cheeks  and  below.  Pectorals  dark.  Mouth 
and  branchial  cavity  intense  black. 

A  single  specimen  was  obtained  by  the  French  explorers  at  station  xxi,  off  the  coast  of 
Morocco,  at  a  depth  of  1,319  meters.  It  was  in  very  bad  condition,  and  the  description  of 
Vaillant  is  confessedly  imperfect. 

No  figure  of  the  other  species,  Salargyreus  Johnsonii,  has  ever  been  published.  Vail- 
lant distinguishes  his  species  from  that  of  Giinther  by  the  following  characteristics:  First, 
by  the  shape  of  the  head,  which  in  II.  brevipes  is  broader  than  high,  in  II.  Johnsonii  higher 
than  broad;  by  the  longer  maxillary  in  the  latter,  in  which  also  the  lower  jaw  does  not  pass 
the  upper  one;  by  the  more  advanced  position  of  the  dorsal  in  the  latter,  which  begins  in 
the  vertical  from  the  root  of  the  pectorals;  ami  also  by  the  prolongation  of  the  first  ventral 
ray.  The  head  of  II.  Johnsonii  would  appear,  from  the  figure  of  Vaillant,  to  be  shorter  than 
that  of  IT.  brevipes. 

It  is  very  desirable,  that  more  material  should  be  studied  before  two  species  of  Halar- 
gyreus are  fully  accepted. 

HALARGYREUS  JOHNSONII,  GCsntiier. 

Salarfltjrewi  Johnsonii,  Guntiieh,  Cat.  Fish.  Brit.  Mus.,  iv,  IS,  :U2  (Madeira,  from  stomach  of  Saceopharynx) ; 
Challenger  Report,  xxii,  1S.<7,  83. 

Head  rather  elongate  and  compressed,  its  length  being  equal  to  the  distance  between 
the  vent  and  the  root  of  the  ventrals;  it  is  much  higher  than  broad,  its  greatest  height 
being  more  than  one-half  of  its  length.  The  snout  is  obtusely  conical,  a  little  longer  than 
the  diameter  of  the  eye,  which  is  one-fourth  of  the  length  of  the  head.  Cleft  of  the  mouth 
wide,  the  maxillary  extending  beyond  the  vertical  from  the  middle  of  the  eye.  Upper  jaw 
without  lip,  that  of  the  lower  very  thin;  the  lower  is  received  within  the  upper,  both  being 
equal  in  length  anteriorly.  A  small  bony  tubercle,  pointing  obliquely  forwards  and  down- 
wards, occupies  the  lower  part  of  the  symphysis  of  the  mandibles.  The  upper  and  lower 
jaws  are  armed  with  a  narrow  baud  of  minute  teeth  of  equal  size.  The  interorbital  space 
is  flattish,  and  its  width  rather  less  than  the  vertical  diameter  of  the  orbit.  Preoper- 
culuni  rounded;  operculum  and  suboperculum  each  terminating  in  a  very  small  spine,  both 
spines  close  together.  The  caudal  fin  is  separated  from  the  other  vertical  fins  by  a  free

Branchiostegals  7;  gill  openings  very  wide,  the  gill  membranes  scarcely  united  below 
the  anterior  third  of  the  orbit;  gills  4,  a  clift  behind  the  fourth;  the  first  branchial  arch 
is  provided  anteriorly  with  long  gill  rakers,  longer  than  the  lamella?  of  the  gills. 

The  greatest  depth  of  the  trunk  is  equal  to  the  distance  between  the  anterior  margin 
of  the  orbit  and  the  end  of  the  operculum.  The  anterior  dorsal  commences  immediately 
behind  the  vertical  from  the  root  of  the  pectoral,  and  is  composed  of  very  slender,  simple, 
and  articulated  rays,  the  anterior  of  which  is  the  longest,  half  as  long  as  the  head.  The 
second  dorsal  commences  immediately  behind  the  first,  and  is  not  much  lower,  its  base  being 
covered  by  a  thin  scaly  membrane.    The  vent  is  situated  iu  the  vertical  from  the  ninth  ray

narrow,  with  flat  base,  the  outer  ray  being  produced  into  a  very  fine  filament  of  moderate 
length.    The  scales  extend  forward  on  the  snout.

This  species,  of  which  a  figure  has  never  been  published,  was  first  described  by  Dr. 
Giinther  from  a  specimen  collected  by  J.  T.  Johnson,  at  Madeira,  from  the  stomach  of  a 
Saccopharynx.  He  informs  us  that  several  specimens  have  since  been  sent  to  the  British 
Museum  from  New  Zealand,  where  it  is  at  times  abundant.

A  genus  of  Gadoidea  having  two  dorsal  fins  and  one  anal,  with  5  elongate,  exserted, 

ventral  rays,  the  median  ones  with  lanceolate  tips;  a  large  abdominal  cone. 

ERETMOPHORUS  KLEINENI5EKGI,  Giglioli. 

Eretmophorus  Kleinenbergii,  (Jiglioli,  Proc.  Zool.  Soc,  London,  1889,  328,  PI.  xxxiv. 

Body  compressed,  tapering  toward  the  tail,  but  less  so  in  the  younger  specimen,  in 
which  the  huge  and  singular  abdominal  cone  is  also  less  developed.  The  height  of  the 
body  behind  the  abdominal  cone  is  contained  between  oh  and  C  times  in  the  total  length 
exclusive  of  the  caudal  fin.  The  lateral  line  extends  nearly  in  a  straight  line  from  the 
branchial  cleft  to  the  end  of  the  root  of  the  tail;  it  is  merely  marked  as  a  furrow  with 
indistinct  pits  along  its  course;  in  the  larger  specimen  at  its  cephalic  end  two  slight  fur- 
rows run  parallel  with  it  above  and  beneath.  The  head  is  moderate,  rather  large;  its 
length  is  contained  about  5  times  in  the  total  exclusive  of  the  caudal  fin;  the  snout  is 
short,  nearly  equal  to  the  transverse  diameter  of  the  eye;  its  anterior  contour  is  rounded; 
there  is  a  slight  median  gibbosity  in  front  over  the  mouth.  This  is  moderate,  its  aperture 
hardly  reaching  the  vertical  from  the  anterior  margin  of  the  eye.  Nostrils  in  front  and  a 
little  above  the  eye,  the  posterior  aperture  largest  and  oval.  Eye  moderate;  behiudit, 
and  extending  toward  the  nape  and  downwards  along  the  preoperculuni,  are  two  series  of 
conspicuous  pores.  The  space  between  the  eyes  is  nearly  flat  and  rather  broader  than  the 
diameter  of  the  eye;  behind,  the  nape  rises  convex,  presenting  a  median  furrow  in  front  of 
the  first  dorsal  in  the  older  specimen.  On  the  nape  in  the  larger  specimen  are  a  number 
of  very  distinct  hyaline  cylindrical  warts,  just  like  those  of  Bellottia  except  in  shape;  the 
latter  have  been  described  by  Prof.  Emery'  and  are  nearly  hemispherical.  In  Eretmo 
phortis  they  begin  just  behind  the  interocular  space  and  appear  to  form  a  double  series;  in 
the  older  specimen  I  counted  eight,  but  a  few  more  extend  toward  the  head  of  the  lateral 
line;  they  are  evidently  sense-organs  allied  to  those  of  the  lateral  Hue.  In  concluding  I 
I  must  state  that  these  warts  are  not  to  be  seen  on  the  two  younger  specimens,  in  which 
they  appear  to  be  represented  by  pores,  more  numerous  and  more  distinct  than  in  the  oldei 
and  larger  specimen.

378  DEEP-SEA   FISHES    OF    THE    ATLANTIC    BASIN. 

The  gill-openings  are  rather  wide,  the  branchiostegal  membranes  are  largely  developed, 
with  robust  rays;  the  opercular  bones  are  smooth  and  very  thin;  the  branchial  cavities 
contain  fonr  complete  arches.  The  specimens  are  so  very  fragile  that  I  did  not  dare  to  puisne 
my  investigations  further. 

The  fins  are  those  of  an  Anacanthine  fish,  but  I  could  not  see  any  transverse  articula- 
tions in  the  first  ray  of  the  first  dorsal;  they  are  not  very  distinct  on  the  other  median  tins 
except  on  the  caudal,  the  only  fin  with  slightly  bifid  rays;  in  the  other  fins  the  rays  are 
simple;  at  the.  base  of  the  long  dorsal  and  anal  fins  the  projecting  heads  of  the  interspinous 
bones  give  rise  to  a  serrated  appearance.  The  first  dorsal  is  small,  but  quite  detached  from 
the  second  one  in  the  two  larger  specimens;  it  rises  just  above  the  insertion  of  the  pecto- 
rals: its  second  ray  is  the  longest  and  equals  in  height  the  commencement  of  the  second 
dorsal  fin.  This  is  greatly  developed  and  maintains  a  nearly  equal  line  throughout,  but  as 
the  body  tapers  toward  the  tail  the  fin  increases  in  height  in  equal  ratio.  In  size,  shape, 
ami  development  the  anal  is  the  exact  counterpart  of  the  second  dorsal  fin.  The  caudal 
fin  is  quite  distinct,  its  contour  is  lanceolate  in  the  smaller  specimen,  nearly  oval  in  the 
older  one,  subtruncate  with  rounded  edges  in  the  oldest  or  biggest  specimen.  The  pectorals 
are  distinctly  lobate,  which  character  is  more  marked  in  the  smaller  specimens;  they  are 
of  moderate  size  and  broadly  oval  in  contour.  The  ventrals  certainly  give  the  most  striking 
feature  to  this  singular  fish;  they  are  inserted  below  and  in  front  of  the  pectorals,  at  the 
base,  and  on  each  side  of  the  great  abdominal  cone.  They  are  of  great  size,  and  the  very 
robust  rays,  ."i  in  number,  are  all  elongated  and  considerably  exceed  the  intervening  mem- 
brane, which  only  unites  their  basal  portions;  the  internal  and  external  rays  are  consider 
ably  less  developed  than  the  three  median  ones,  the  internal  one  is  the  shortest;  both  are 
simple  and  without  any  trace  of  terminal  dilatations.  The  three  median  rays  all  terminate 
in  a  large  beautiful  lanceolate  leaf  like  blade,  through  which,  however,  the  ray  continues 
to  the  pointed  extremity;  they  are  all  prolonged  beyond  the  two  first-mentioned  rays,  hut 
the  outer  one  is  considerably  shorter  than  the  other  Two;  it  is  smooth  and  its  terminal  blade 
is  smaller.  The  third  and  fourth  rays,  counting  from  the  outer  one.  are  subequal,  and  bent 
backwards  extend  very  nearly  to  the  root  of  the  tail;  at  about  the  basal  third  of  their 
length  they  both  present  a  singular  angular  dilatation,  which  looks  like  a  thickened  articula- 
tion, but  which  is  merely,  so  far  as  I  can  make  out.  a  membranous  dilatation.  The  great  lan- 
ceolate terminal  blades  are  very  large,  being  little  less  than  one-fourth  of  the  total  length 
of  the  ray  which  supports  them;  their  edges  are  sinuous  and  they  terminate  in  a  fine  point. 
Judging  from  their  length,  strength,  and  development,  these  ventral  paddles  must  be  most 
efficient  for  swimming;  I  know  of  no  other  fish  possessing  anything  like  them,  and  have, 
therefore,  thought  proper  to  derive  from  so  peculiar  a  character  the  generic  name  which  I 
have  proposed  for  this  singular  fish. 

The  next  remarkable  feature  of  my  Eretmophorus  is  the  huge  abdominal  cone,  the  base 
of  which  occupies  the  entire,  space  between  the  insertions  of  the  ventrals  and  that  of  the 
anal  fin.  This  cone  appears  to  deyelop  with  age.  and  it  is  certainly  larger  and  more  prom- 
inent in  my  oldest  and  biggest  specimen,  equaling  in  height  that  of  the  body  just  behind 
the  pectorals,  where  it  is  greatest.  This  abdominal  cone  is  quite  smooth;  its  skin,  devoid 
of  scales,  is  silvery.  1  have  not  ventured  to  open  it  in  any  of  the  three  specimens  yet  dis- 
covered, for  fear  of  damaging  to  a  certainty  these  rare  and  very  delicate  creatures;  but 
the  supposition  that  it  contains  most  of  the  alimentary  canal  can  not  be  far  from  the  truth; 
at  its  apex,  which  becomes  cylindrical,  is  an  aperture,  evidently  the  vent,  and  behind  this 
a  slender  conical  papilla  on  which  1  could  not  distinguish  anything  like  an  opening. 

The  scales  cover  the  whole  body  except  the  head  and  abdominal  cone,  which  are,  as  I 
have  said  before,  naked.  They  are  small,  very  adherent,  cycloid,  and  marked  with  con- 
centric lines.  I  have  figured  a  few  magnified  (pi.  xxxiv,  tig.  1),  to  give  an  exact  idea  of 
their  characters;  they  are  very  similar  to  those  of  Hypsirhynchus  hepatieus,  Facciola.  A 
thin  pellucid  epidermal  layer  covers  them. 

Only  three  specimens  of  Eretmophorus  Kleinenbergi  have,  so  far  as  I  know,  yet  been  cap- 
tured and  preserved;  they  were  caught  alive  with  a  hand-net  along  with  other  pelagic  an- 
imals on  the  surface  at  the  mouth  of  the  harbor  of  Messina  as  the  current  was  flowing  in. 


DISCUSSION   OF    SPECIES    AM)    THEIR    DISTRIBUTION.  379 

1  owe  them  to  the  kindness  of  my  friend,  Prof.  Nicolaus  EQeinenberg,  director  of  the 
Zoological  Institute  of  the  Messina  University,  to  whom  I  owe  many  other  ichthyological 

rarities;  and  as  a  mark  of  my  gratitude  and  esteem  I  have  though!  proper  to  give  his  name 
to  so  singular  a  species,  which  is  evidently  as  yet  undescribed.  These  specimens  air  now 
in  the  central  collection  of  Italian  vertebrata  in  the  Royal  Zoological  Museum  at  Florence. 
As  they  present  differences  in  size  and  in  other  respects,  1  shall  proceed  to  describe  them 
briefly. 

My  smallest  specimen  (pi.  xxxrv,  fig.  2)  measures  28£  millimeters  in  total  length;  it 
was  caught  on  the  Kith  of  .May,  1887.  It  is  evidently  much  younger  than  the  other  two: 
the  two  dorsals  are  yet  muted  and  the  larval  median  tin  extends  as  a  crest  to  the  head. 
The  caudal  is,  however,  quite  distinct  and  remarkable  for  its  lanceolate  form.  The  abdom- 
inal cone  is  comparatively  smaller  than  in  the  two  older  specimens,  and  a  membrane  unites 
its  hinder  portion  to  the  anal  tin.  The  lobe  of  the  pectorals  is  very  distinct,  and  the  rays 
look  thickened  at  their  distal  ends.  The  ventrals  have  the  characteristic  form  and  develop- 
ment. The  color  of  the  body  is  yellowish  white  (in  alcohol);  8  very  distinct  broad  black 
hands  cross  the  body  transversely,  being  slightly  oblique:  tin;  first  occupies  the  base  of  (he 
abdominal  cone,  the  last  the  root  of  the  tail;  the  fourth,  fifth,  sixth,  and  seventh  are  con- 
tinued as  a  black  blotch  on  the  base  of  the,  anal  tin;  the  ventral  paddles  are  tipped  and 
edged  with  black:  the  ray  is,  however,  white;  otherwise  the  litis  are  colorless.  Looking 
with  a  lens,  these  black  bands  and  blotches  result  in  an  accumulation  of  dark  points  or 
chromatophores;  this  is  the  case  also  in  the  other  specimens. 

The  second  specimen,  according  to  size  and  age,  measures  OS  millimeters  in  total 
length;  it  is  figured  slightly  enlarged  (pi.  xxxiv,  fig.  3).  It  was  captured  alive  near  the  sur- 
face in  the  harbor  of  Messina  on  the  2d  of  June,  1888.  It  bears  considerable  resemblance 
to  the  first  specimen  described,  but  has  lost  some  of  the  larval  characters  above  noted ;  all 
the  median  fins  are  well  distinct;  the  caudal  has  an  oval  contour,  but  the  abdominal  cone, 
covered  with  a  slightly  silvery  skin,  shows  still  a  posterior  membranous  fringe  which  par- 
tially unites  it  with  the  anal  tin.  The  pores  on  the  head  and  nape  are  very  distinct.  In 
color  this  specimen  is  also  very  similar  to  the  first  one;  the  black  transverse  bands  are 
very  well  marked,  but  they  are  slightly  fainter  and  the  first  one  does  not  extend  to  the 
abdominal  cone,  which  is  well  developed.  Ten  very  distinct  black  blotches  extend  along 
the  base  of  the  anal  flu  aud  three  along  the  caudal  end  of  the  second  dorsal;  three  addi- 
tional blotches  are  on  the  back  between  the  third  and  fourth,  fifth  and  sixth,  and  sixth  and 
seventh  transverse  bands. 

The  third  specimen  has  the  aspect  of  an  adult.  It  was  caught  also  near  the  surface 
at  the  entrance  to  the  harbor  of  Messina  at  the  end  of  April,  1884.  It  measures  78  milli- 
meters in  total  length;  head,  111  millimeters;  from  nape  to  apex  of  abdominal  cone,  27  milli- 
meters; height  of  body  immediately  behind  the  abdominal  cone,  12  millimeters.  I  have 
figured  it  once  and  a  half  the  natural  size  (PL  xxxiv,  Fig.  4).  It  differs  especially  in  color 
from  the  two  .younger  and  smaller  specimens;  the  transverse  dark  bands  on  the  body  and 
blotches  along  the  median  fins  are  faintly  marked.  The  paddles  of  the  ventral  (ins  arc 
tipped  with  blackish  brown,  and  were  edged  with  violet  in  the  fresh  specimen,  the  general 
color  of  which  was  a  faint  pink,  with  yellowish  tinge  along  the  basal  half  of  the  dorsal  and 
anal  tins.  The,  abdominal  cone  is  bright  silvery;  it  has  no  trace  of  a  hind  marginal  mem- 
brane. The  caudal  is  subtruncate;  and,  lastly,  the  cylindrical  hyaline  warts  on  the  nape 
are  very  prominent  and  distinct.     (Giglioli.) 

HYPSIRHYNCHUS,  Faeeiola. 

Hypnrhynchus,  FACClOLi,  Naturalista  Siciliano,  in,  pi.  u. 

A  genus  of  Gadoidea  related  to  Eretmopliorus,  but  having  seven  ventral  rays,  slightly 
prolonged,  and  with  rounded,  rather  than  lanceolate,  tips.     No  abdominal  roue.

HYPSIKHYNCHUS  HEPATICUS,  Facciola. 

Hypsirhynclme  hepaticus,  Facciola,  loc.  cit. 

This  species  was  obtained  at  Messina  by  Dr.  L.  Facciola,  and  is  also  represented  by  a 
Naples  specimen  in  the  Florence  Museum.  It  has  not  been  fully  described,  nor  have  we 
seen  even  the  partial  description  in  the  Naturalista  Siciliano. 

STRINSIA,  Rafinesque.    (Figure  32G.) 

Strinsia,  Rafinesque,  Indice  d'  Ittiologia  Siciliana,  1880,  51. — Gi'NTHEK,  Cat.  Fish.  Brit.  Mus.,  iv,  1862,  344. 

This  genus  was  briefly  characterized  by  Rafinesque  in  the  following  terms : 

"Gen.  Strinsia.    Due  ale  dorsali,  una  ala  anale  riunita  all'  ala  caudale." 

Giinther's  fuller  diagnosis  would  appear  to  have  been  drawn  from  a  study  of  the 
description  and  figure  in  the  "Iconografia"  of  Prince  Bonaparte,  who  seems  to  have  had  a 
sight  of  Rafinesque's  type. 

Strinsia  is  known  only  from  this  one  specimen,  carelessly  described,  and  probably  care- 
lessly preserved  nearly  a  century  ago.  The  careful  work  of  later  Italian  and  French  ex- 
plorers has  not  brought  the  form  again  to  notice.  Conservative,  and  careful  writers  like 
Giglioli,  who  has  systematically  reviewed  all  of  Rafinesque's  collecting  fields  about  Sicily, 
are  beginning  to  omit  it  from  their  fauna!  lists.     Something  must  be  wrong. 

What,  then,  is  Strinsia,  or  rather,  what  was  it?  This  is  a  question  which  we  shall  not 
attempt  to  answer,  except  by  a  suggestion.  May  not  Rafinesque's  type  have  been  a  fish 
belonging  to  some  closely  related  genus,  whose  tail  had  been  deformed  or  partially  restored 
after  mutilations;  or,  indeed,  may  not  Bonaparte's  figure,  as  well  as  Rafinesque's  diagnosis, 
have  been  drawn  from  a  badly  preserved  specimen,  with  the  caudal  rays  and  those  of  the 
posterior  parts  of  the  dorsal  and  anal  frayed  out  and  imperfect? 

The  tail  of  Bonaparte's  figure  does  not  look  natural.  The  figure,  except  for  the  tail, 
answers  very  well  to  the  description  of  Ralargyreus. 

The  only  species  named  under  Strinsia  is  S.  tinea,  Rafinesque  (op.  cit.,  12,  52).

This  form  is  known  from  Greenland,  whence  the  museum  at  Copenhagen  obtained  2 
specimens,  taken  in  1836  from  the  stomach  of  a  seal  (Cystophora)  at  Otuenak  (lat.  70°  N"). 
Another  was  found  in  1882  by  the  IT.  S.  Fish  Commission  steamer  Fish  Hawk  in  hit.  40°,  off 

the  coast  of  New  Jersey,  in   l.lllli  fathoms. 

The  body  is  unusually  high,  the  greatest  height  at  anus  contained  4.]  times  in  length  ex- 
clusive of  caudal.  The  head  enters  5J  times  in  the  length  to  end  of  caudal  peduncle  and 
(i  times  in  total  length;  its  width  at  cheeks  equals  two-thirds  of  the  head's  length. 

The  eyes  are  rather  large,  nearly  as  long  as  snout  and  the  interorbital  area,  ami  are 
entirely  in  the  anterior  half  of  head,  the  posterior  margin  of  the  orbit  nearly  equidistant

norma];  the  supramaxillary  ends  under  the  posterior  margin  of  the  pupil.  The  teeth  are 
in  a  narrow  band  in  both  jaws  and  some  of  those  at  least  in  the  outer  row  of  upper  jaw  arc 
slightly  enlarged  and  brownish  colored.  The  teeth  of  the  vomer  forma  short  curved  band  in 
two  rows.  The  nasal  barbel  about  equals  the  diameter  of  the  eye.  The  chin  barbel  is 
small  and  does  not  much  exceed  one-half  the  diameter  of  the  eye. 

The  foremost  ray  of  the  first  dorsal  springs  from  the  back  above  opercular  margin. 
The  second  dorsal  tin  is  low  in  front  but  rises  rapidly  to  the  seventh  or  eighth  rays  behind 
which  it  is  nearly  uniform  for  a  long  distance  and  the  highest  at  posterior  portion. 

The  anal  fin  is  much  lower  than  the  second  dorsal.  The  caudal  is  slightly  emarginate, 
almost  truncate  behind,  and  its  median  rays  are  about  two-thirds  as  long  as  the  head. 

The  pectorals  are  nearly  three-fourths  as  long  as  head  and  are  produced  toward  the 
upper  angles,  the  third  ray  being  longest. 

The  ventral  tins  have  their  basis  mostly  in  advance  of  the  pectorals,  and  the  longest 
ray  is  filamentous  and  nearly  equals  the  pectoral. 

The  lateral  line  is  obsolescent. 

The  Albatross  obtained  specimens  of  this  species  from  the  following  localities:  Cat. 
No.  33430,  T.  S.  X.  M.,  from  station  2072,  in  41°  53'  N.  lat.,  65°  35'  \V.  Ion.,  at  a  depth  of

This  species  is  a  resident  of  the  deep  waters  of  Massachusetts  Bay,  and  has  frequently 
been  found  outside  the  100 fathom  curve  at  the  bottom.  Its  young  swim  at  the  surface  in 
the  latter  part  of  summer  aud  fall,  and  have  hitherto  beeu  identified  with  the  little 
Mackerel  Midge,  Ciliata  argentata.  We  have  examined  numerous  specimens  which  pur- 
ported to  be  Ciliata,  and  have  found  them  in  every  case  to  be  the  young  of  this  species. 
English  ichthyologists,  indeed,  record  Ciliata  as  the  larval  form  of  Motella,  and  if  this  be 
uot  the  case  we  doubt  if  the  genus  Ciliata  has  ever  been  observed  in  the  Western  Atlantic.

Color,  brownish,  mottled;  young  uniform  dark  slate-color  or  with  transverse  yellow 
bands;  vertical  fins  bordered  with  blackish,  and  with  a  white  edge. 

The  disk  or  Torsk  lives  on  the  offshore  banks  of  northern  New  England.  In  Europe, 
according  to  Giiuther,  its  range  is  from  30  to  120  fathoms,  and  an  adult  was  obtained  by 
the  Knight  Errant,  in  18S0,  in  the  Faroe  channel,  at  the  depth  of  530  fathoms.  On  the 
New  England  coast  it  is  a  common  resident  of  the  inshore  fishing  grounds,  where  it  occurs 
in  great  abundance,  lurking  among  the  stones,  but  is  soon  caught  up  by  the  fishermen  after 
the  discovery  of  a  new  bank.    It  occurs  as  far  out  as  the  250  or  300  fathoms  line.

Its  head  is  twice  as  long  as  the  height  of  the  body,  a  little  higher  than  broad,  with  an  ob- 
tuse, truncated  muzzle,  whose  length  is  one-fourth  that  of  the  head.  Mouth  moderate, 
the  maxillary  reaching  to  the  vertical  from  the  center  of  the  eye;  the  lower  jaw  slightly 
the  longer.  Teeth  in  both  jaws  small,  conical,  in  2  rows;  vomer  and  palatine  without 
teeth.  Diameter  of  the  eye  one-fourth  the  length  of  the  head;  interorbital  space  three-

Color  dark  gray,  dull  silvery  below;  upper  edge  of  pectoral  blackish. 

The  whiting,  or  silver  hake  of  the  eastern  United  States  ranges  from  New  York  to 
the  Gulf  of  St.  Lawrence,  where  it  is  common,  especially  in  the  Hay  of  Chaleur,  although 
it  has  been  rarely  observed  as  far  north  as  the  Strait  of  Belleisle.  It  has  been  found  at 
considerable  depths  as  far  south  as  lat.  36°  and  37°,  as  is  shown  in  the  following  list  of 
stations.  It  appears  to  spawn  in  the  fall,  at  a  depth  of  80-150  fathoms,  off  the  mouth  of 
Xarragansett  Bay,  and  there  is  no  evidence  that  it  ever  breeds  except  at  considerable 
depths.

Body  fusiform,  compressed  posteriorly,  covered  with  cycloid  scales  of  moderate  size. 
Two  dorsal  fins;  the  anterior  reduced  to  a  single  long  ray  ou  the  occiput;  the  second  and 
the  anal  much  depressed  in  the  middle,  nearly  divided  into  two;  ventrals  very  long,  com- 
posed of  5  rays,  the  outer  of  which  are  very  elongate.  Minute  movable  teeth  round  the 
margin  of  the  mouth  and  on  the  vomer;  none  on  the  palatines.  No  air  bladder;  no  pyloric 
appendages.  Gill  openings  very  wide,  the  gill  membranes  being  united  below  the  throat, 
not  attached  to  the  isthmus.    Pseudobranchiaj  none;  7  branchiostegals.     (Gunther.) 

The  type  species,  B.  Macclellandii,  Thompson,  is  known  from  the  China  seas,  the  Pacific 
near  the  Philippines,  and  the  Indian  Ocean.  This  genus  has  recently  been  added  to  the 
Atlantic  fauna  in  the  form  of  a  well-marked  species. 

Alcock  obtained  numerous  young  specimens  of  a  species  of  Bregmaceros  in  the  Lacca- 
dive  Sea,  in  95  fathoms  (Alcock,  Ann.  and  Mag.  Nat.  Hist.,  July,  1891, 29).

The  species  agree  very  closely  with  B.  Macclellnndii,  Thompson,  from  which,  however, 
it  differs  in  the  lesser  number  of  rays  in  the  first  anal,  and  in  the  greater  height  of  the 
vertical  fins  (judging  from  figures). 

The  type  (cv)  is  46  millimeters  long  to  base  of  caudal.  Form  compressed,  moderately 
elongate.  Body  height  (6  millimeters)  73}  in  its  leugth.  Interorbital  area  convex,  its  width 
(2i  millimeters)  greater  than  diameter  of  eye  (2  millimeters),  which  is  4  in  length  of  head 
(8  millimeters).     Length  of  head  5|  in  total.    Jaws  even  in  front. 

Maxilla  reaches  to  vertical  through  middle  of  eye;  the  mandible  to  vertical  through 
posterior  margin  of  eye. 

Teeth  on  intermaxillary  minute,  apparently  in  a  single  series;  mandibulary  teeth 
biserial,  the  inner  teeth  enlarged. 

Scales  large,  about  10  in  a  transverse  series,  about  65  in  a  longitudinal  series.

Short  sunlit,  subtrihedral,  pointed  in  front,  much  shorter  than  the  large  eye,  which  is 
one-third  or  two-fifths  the  length  of  the  head  in  adult  specimens.  Intermaxillary  very  short, 
one-half  length  of  maxillary,  and  not  continued  beyond  its  expanded  vertical  process.  The 
eye  is  oblong.  The  whole  under-surface  of  the  head  below  the  suborbital  and  nasal  ridge  is 
naked.  Axil  ofpectoral  naked.  Space  between  the  veutrals  scaled.  Body  scales  each  with  a 
single  strong  median  keel,  made  ii|>  of  5  or  8  spines  directed  backwards.  Some  scales,  par- 
ticularly of  the  head,  have  also  2  lateral  keels.  There  arc  U  longitudinal  scries  of  scales 
between  the  first  dorsal  fin  and  the  lateral  line.  The  first  dorsal  spine  indistinctly  denticu- 
lated towards  the  point.  The  length  of  the  pectoral  is  nearly  or  quite  one-half  the  length 
of  the  head.  The  longest  spine  of  the  dorsal  is  very  finely  serrated  along  its  anterior 
margin,  the  serrations  becoming  obsolete  near  its  base.  Vent  situated  behind  the  origin 
of  the  second  dorsal  fin.  Gill-rakers  very  small,  tubercular;  9  to  11  on  the  first  arch.  The 
gill-membranes  broadly  joined,  free  from  the  isthmus  behind.

This  form,  originally  discovered  on  the  coast  of  Norway,  has  been  found  abundantly  as 
far  south  as  Georges  Bank,  where  the  halibut  fishermen  catch  it,  or  som  ■  closely  allied 
form,  on  their  trawls.  The  first  specimen  seen  by  American  naturalists  was  picked  up 
floating  at  the  surface,  off  the  mouth  of  New  York  Harbor.  The  Albatross  obtained  it  from 
station  2528,  in  41  -  47'  N.  lat.,  65°  37'  30"  W.  Ion.,  at  a  depth  of  677  fathoms.  Gunther 
knew  it  from  Finmark  and  Greenland, as  well  as  from  New  England.  He  calls  attention  to 
remarkable  individual  variations  in  the  specimens  examined  by  him.  His  critical  remarks 
in  this  connection  are  of  great  importance.     (Challenger  lleport,  xxu,  130.)

Snout  conically  projecting  beyond  the  mouth,  with  sharp  and  smooth  canthus  rostralis; 
a  rough  protuberance  in  front,  and  one  on  each  side  of  the  canthus.  Mouth  rather  small, 
situated  at  the  lower  side  of  the  snout;  infraorbital  ridge  sharp,  prominent  in  its  whole 
length.  The  cleft  of  the  mouth  docs  no!  extend  to  below  the  center  of  the  eye.  Teeth  in 
villiform  bands,  in  both  jaws;  those  of  the  outer  series  of  the  upper  jaw  scarcely  stronger 
than  the  others.  Barbel  short  and  slender.  Interorbital  space  flat,  its  width  being  equal 
to  the  vertical  diameter  of  the  eye.  The  horizontal  diameter  of  the  eye  equals  the  length 
of  the  snout,  and  is  two-sevenths  of  that  of  the  head. 

The  scales  are  covered  with  very  small  spinelets,  which  are  arranged  in  about  nine  series, 
the  middle  series  1  icing  some  times  more  prominent  than  the  others;  only  the  terminal  spine 
lets  id' the  central  series  projects  sometimes  beyond  the  margin  of  the  scale.  There  are 
(i  scales  in  a  transverse  series  between  the  first  dorsal  spine  and  the  lateral  line.  Second 
dorsal  spine  somewhat  produced,  armed  in  front  with  rather  closely  set  barbs.  The  dis- 
tance between  the  2  dorsal  lins  equals  the  length  of  the  head,  the  snout  not  included. 
The  outer  ventral  ray  produced  into  a  filament.     Color,  brown.

392  DEEP-SEA    FISHES    OF   THE   ATLANTIC    BASIN. 

The  form  identified  by  Giinther  with  the  Canarian  species  of  Webb  and  Berthelot  was 
obtained  90  miles  southeast  of  Cape  St.  Vincent,  at  a  depth  of  1,090  fathoms.  He 
believes  it  to  be  the  same  as  the  Mediterranean  species  placed  under  the  name  by  Vincigu- 
erra.  The  French  explorers  obtained  141  specimens  off  Morocco,  Soudan,  and  the  Canaries, 
at  500  to  2,G00  fathoms. 

Macrurus  smiliophorus,  Vaillant  (242,  PI.  xxn,  Fig.  1),  is  very  close  to  M.  sclerorhynchus, 
as  may  be  seen  by  comparison  of  his  figure  with  that  of  Vinciguerra.  The  differences  in 
the  squamation  and  in  the  form  of  the  sagitta  do  not  appear  to  be  sufficiently  demonstrated 
to  warrant  the  acceptance  of  his  species.  All  his  specimens  were  obtained  from  the  region

Snout  conical,  projecting  beyond  the  mouth,  with  rather  obtuse  and  rough  upper 
edge;  the  left  of  the  mouth  extends  nearly  to  below  the  center  of  the  eye.  The  teeth  of 
the  outer  series  are  visibly  stronger  than  the  remainder.  Barbel  slender,  but  not  so  lougas 
the  eye.  The  upper  profile  rises  rather  suddenly  towards  the  anterior  dorsal  spine.  The 
interorbital  space  is  fiat,  its  width  being  considerably  less  than  the  diameter  of  the  eye, 
which  conspicuously  exceeds  the  length  of  the  snout,  and  is  one-third  or  rather  more 
than  one-third  the  length  of  the  head.  The  scales  are  equally  rough  over  the  whole 
of  their  surface,  the  spiuelets  being  subequal  in  size,  densely  packed,  but  arranged  in 
from  8  to  12  series,  the  middle  series  not  being  more  prominent  than  the  others  (as  is 
the  case  in  Macrurus  sclerorhynchus).  The  entire  margin  of  the  scale  is  spinous.  There 
are  8  scales  in  a  transverse  series  between  the  first  dorsal  and  the  lateral  line.  Second 
dorsal  spine  somewhat  produced,  armed  along  its  anterior  edge  with  barbs  pointing 
upwards  and  rather  closely  set.  The  second  dorsal  fin  commences  at  a  distance  from  the 
first  which  is  less  than  the  length  of  the  head.  The  outer  ventral  ray  not,  or  but  slightly, 
produced.    Lower  part  of  the  head  and  autero-superior  portion  of  the  first  dorsal  black.

The  description  quoted  above  is  very  indefinite :  Giinther  places  the  name  of  Lowe  doubt 
fully  in  the  synonymy  of  M.  oequalis.    It  is  closer,  however,  to  M.  sclerorhynchus,  having  a

Body  tapering  from  first  dorsal  to  tip  of  tail,  much  compressed  posteriorly,  its  greatest 
lieighl  over  origin  of  pectorals  (0.037  meter)  contained  8  times  in  length;  its  greatest  width 
at  the  same  point  (0.022  meter,  contained  13  times  in  length. 

Scales  irregularly  polygonal,  the  free  portions  covered  with  transparent,  vitreous  spines, 
arranged  in  from  10  to  12  irregular  longitudinal  rows.  On  head  and  upper  part  ofbody, 
in  advance  of  first  dorsal,  the  median  row  of  spines  is  the  most  prominent,  and  presents 
the  appearance  of  a  low  median  keel. 

Lateral  line  nearly  straight,  formed  by  a  smooth  groove,  whieh  replaces  two  or  three 
median  rows  of  spines  of  each  scale.  Number  of  scales  in  lateral  line,  152;  6  transverse 
rows  above  it  and  10  or  20  rows  below  it,  counting  from  vent  obliquely  backward. 

Greatest  length  of  head  (0.045  meter)  equals  distance  between  first  and  twenty  third 
anal  rays,  and  is  contained  Gi  times  in  extreme  length.  Greatest  height  at  posterior  mar- 
gin of  orbit  (0.028  meter),  greater  thau  width  at  same,  point  (0.023  meter),  If  times  in 
length  of  head.  Width  of  interorbital  area  (0.012  meter)  equal  to  length  of  snout  (0.013 
meter)  and  length  of  maxillary  (0.013  meter).  Length  of  postorbital  region  (0.017  meter), 
about  equal  to  horizontal  diameter  of  orbit  (0.010  meter).  Length  of  operculum  (0.007 
meter)  about  half  the  length  of  mandible  (0.015  meter). 

Snout  sharp,  a  front  view  presenting  four  ridges  radiating  from  the  tip  at  right  angles 
to  each  other,  the  lower  one  being  merely  a  fold  in  the  skin  of  the  under  surface  of  the 
head.  The  horizontal  ridges  are  continued  into  the  ridges  upon  the  suborbitals.  Ridge 
extending  backward  from  tip  of  snout  upon  top  of  head  is  lost  in  the  interorbital  space. 
Branches  of  the  horizontal  ridges  are  continued  upon  the  upper  margins  of  orbits,  and 
there  disappear.     Nostrils  immediately  in  front  of  orbit,  the  posterior  pair  much  the  longer. 

Mouth  situated  entirely  on  lower  side  of  head;  symphysis  of  lower  jaw  in  vertical  from 
anterior  margin  of  orbit,  and  articulations  of  mandibles  in  vertical  from  posterior  margin 
of  orbit;  width  of  cleft  of  mouth  (0.012  meter)  equal  to  distance  between  symphysis  of 
maxillaries  and  line  connecting  their  articulations.  Upperjaw  protractile  vertically.  Barbel 
0.005  meter  in  length. 

Teeth  conical,  somewhat  recurved,  of  nearly  uniform  size,  arranged  in  villiform  bands. 
Palate  smooth. 

Distance  of  first  dorsal  from  snout  (1.057  meters)  about  4  times  the  length  of  its  base 
(0.014  meter),  and  from  anterior  margin  of  orbit  equal  to  length  of  head.  First  spine  very 
short  (0.002  meter,)  not  much  longer  than  the  teeth  of  the  second  spine.  Second  spine  in 
length  (0.032  meter)  twice  horizontal  diameter  of  orbit,  stout,  its  anterior  margin  armed 
from  base  to  tip  with  15  teeth  pointing  upward,  the  uppermost  slender;  its  length  to 
tip  of  filament  (0.03  meter)  is  almost  equal  to  distance  from  origin  of  second  dorsal  (0.038 
meter),  this  tip  when  laid  back  reaching  almost  to  second  dorsal.  Hays  decreasing  regu- 
larly in  length,  so  that,  whei  the  tin  is  upright,  its  shape  approximates  that  of  a  right- 
angled  triangle,  the  liypothenuse  of  which  is  the  second  dorsal  spine  and  its  perpendicular 
side  a  line  touching  the  tips  of  t  he  rays. 

Length  of  base  of  second  dorsal  (0.204  meter)  less  than  that  of  the  anal,  its  origin 
over  the  thirtieth  scale  of  lateral  line.  Length  of  longest  ray  (in  posterior  third)  0.004 
meter,  which  is  less  than  length  of  barbel.  Ail  rays  very  feeble.  .Membrane  scarcely 
perceptible. 

Distance  of  anal  from  snout  (0.070  meter)  3£  times  in  its  length  of  base,  its  origin  under 
ISth  scale  of  lateral  line.  Length  of  first  ray  (0.006  meter)  one  half  the  Length  of  tenth 
ray  (0.012  meter),  and  3  time.;  the  length  of  last,  ray  (0.002  meter),  the  length  of  rays  increas-

394  DEEP-SEA   FISHES    OF    THE    ATLANTIC    BASIN. 

Distance  of  pectoral  from  snout  (0.048  meter)  4  times  width  of  interorbital  area;  its 
length  (0.029  meter)  twice  the  length  of  inaudible.  Insertion  above  the  middle  of  the  depth 
of  the  body,  on  a  level  with  center  of  orbit,  its  third  ray  longest,  its  tip  reaching  to  vertical 
from  base  of  fourth  anal  ray. 

Insertion  of  ventral  behind  pectoral  and  almost  under  that  of  first  dorsal;  its  distance 
from  snout  (0.053  meter)  slightly  exceeding  twice  its  length  (0.025  meter).  Tip  of  ventral 
filament  reaches  to  base  of  third  anal  ray. 

Radial  formula:  D.  n,  11,  137;  A.  120;  F.  15;  V.  7. 

Color:  Ground  color,  light  brownish  gray;  under  parts,  silvery;  belly,  darker,  bluish. 
Under  surface  of  snout,  pink,  as  is  also  the  first  dorsal  except  spines.  Spines  of  dorsal, 
ventral  and  anterior  anal  rays,  blackish.  Throat,  branehiostegal  membrane  and  isthmus, 
rich  deep  violet.     Sclerotic  coat,  green.     Eyes,  very  dark  blue. 

Spermaries  well  developed,  but  milt  not  mature.     Individual  apparently  adult. 

The  species  was  dedicated  to  Prof.  Spencer  F.  Baird,  and  was  the  first  deep-sea  fish 
obtained  by  the  Fish  Commission  or  described  by  an  American  ichthyologist.  It  ranges 
from  150  to  1,255  fathoms. 

This  species  is  distinguished  by  Giinther  from  his  Macrurus  aqualis,  which  it  closely 
resembles,  (1)  by  its  longer  snout,  which  is  nearly  equal  to  the  diameter  of  the  eye;  and  (2) 
the  smaller  number  of  the  ventral  rays  (7).

Snout  moderately  produced,  as  long  as  the  eye,  which  is  large,  one-third  of  the  length  of 
the  head,  its  vertical  diameter  being  considerably  more  than  the  width  of  the  interorbital 
space.  Anterior  edge  of  the  snout  with  three  rough  prominences,  one  in  the  middle  and 
one  on  each  side.  Mouth  inferior,  lower  side  of  the  head  naked.  Each  scale  with  a  median 
series  of  spinelets,  and  with  two  or  more  isolated  spinelets  besides;  the  medians  are  the 
strongest,  forming  with  their  fellows  continuous  longitudinal  lines  on  the  body.  Upper 
and  lateral  portions  of  the  head  covered  witli  irregular,  rough  scales;  lower  naked.  There 
are  five  scales  in  a  transverse  series  between  the  first  dorsal  spine  and  lateral  line.  Teeth

expedition  to  Egypt  and  Arabia.  It  is  known  from  the  Gnlf  of  Genoa,  the  sea  of  Nice 
(Risso),  and  about  Sicily  (Bonaparte  and  Diklerlein);  and  Gasco  observed  two  from  the 
Gulf  of  Naples.  Vaillant  records  it  in  411-560  meters,  bum  the  Azores,  and  Cape  Verdes, 
from  off  Soudan,  the  Banc  d'Arguin,  and  the  Gulf  of  Gascony.  Collett  obtained  it  from  off 
Bergen,  in  the  stomach  of  a  codfish,  and  numerous  specimens  have  been  taken  off  the  coast 
of  Ireland  in  250  fathoms.  (Giinther,  Ann.  and  Mag.  Nat.  Hist.,  Dec,  1SS9,  117.)  Yin

CCELORHYNCHUS  CARMINATUS,  Goode.     (Figure  336.)

Zool.,  x,  196. 
Macrurus  (Coelorhynchus)  carminatus,  Guntiier,  Challenger  Report,  XXII,  129,  pi.  v,  (ig.  13. 

Tbe  body  is  less  elongate  and  stouter  than  in  M.  Bairdii,  Goode  and  Beau,  though  its 
greatest  height  (12.5)  is,  as  in  M.  Bairdii,  one-eighth  of  total  length.  The  difference  in 
general  appearance  is  the  ventral  contour  retreats  less  rapidly  in  M.  carminatus. 

The  scales  are  large,  heavy,  the  free  portions  covered  with  long  vitreous  spines 
arranged  in  9  or  10  rows.  These  scales  resemble  the  old-fashioned  wool  cards.  Hence 
the  specific  name,  from  carmen,  a  wool  card.  The  spines  are  thicker  and  more  closely  set 
than  in  M.  Bairdii,  and  there  is  no  specialization  of  the  central  row.  The  number  of  scales 
in  the  lateral  line  can  not  be  determined,  though  it  probably  does  not  exceed  100,  but  there 
are  about  5  transverse  rows  above  it  and  15  or  16  below  it,  counting  from  the  vent  obliquely 
backward.     In  If.  Bairdii  there  are  152  in  the  lateral  line,  6  above  and  19  or,20  below. 

Length  of  head  contained  a  little  less  than  5  times  in  total  length.  Width  of  interor- 
bital  area  about  equal  to  vertical  diameter  of  orbit,  and  about  one-fifth  of  the  length  of  the 
head.  Length  of  snout,  horizontal  diameter  of  eye,  length  of  postorbital  portion  of  head 
about  equal.     Length  of  operculum  half  that  of  snout. 

Snout  long,  sharp,  depressed,  triangular,  the  lower  surface  more  nearly  parallel  with 
the  axis  of  the  body  than  in  M.  Bairdii.  The  lateral  ridges  are  pronounced  and  are  con- 
tained in  a  straight  line  under  the  eyes  and  upon  the  preopercula.  Strong  horizontal 
ridges  continue  from  the  supraorbital  margins  to  the  gill  openings,  parallel  with  the 
subocular  ridges.     Nostrils  immediately  in  front  of  the  orbit.     Barbel  very  short. 

Teeth  small,  conical,  somewhat  recurved,  arranged  in  villiform  bands. 

Distance  of  first  dorsal  from  snout  (23.5)  about  li  times  the  length  of  its  base  (5),  its 
distance  from  anterior  margin  of  orbit  much  less  than  the  length  of  the  head.  First  spine 
very  short,  hardly  perceptible  above  the  skin.  Second  spine  about  half  as  long  (11)  as  the 
head,  slender,  unarmed.  When  laid  back,  its  tip  reaches  the  oi'igin  of  the  second  dorsal  or 
beyond.  The  decrease  in  the  length  of  the  spines  is  very  gradual,  the  sixth  being  nearly  as 
long  as  the  second,  so  that  the  fin  is  not  so  triangular  in  shape  as  in  31.  Bairdii. 

The  second  dorsal  begins  in  the  perpendicular  from  the  seventh  ray  of  the  anal.  The 
anal  is  much  higher  than  in  .1/.  Bairdii,  nearly  equal  to  half  the  width  of  the  interorbital 
area. 

Anal  fin  inserted  under  the  eighteenth  scale  of  the  lateral  line  (as  nearly  as  can  be 
judged  from  the  distorted  specimen).  It  longest  rays  are  as  long  as  the  width  of  the 
interorbital  area. 

Distance  of  pectoral  from  snout  equal  to  twice  its  own  length  (11),  which  is  about 
equal  to  the  length  of  the  dorsal  spine.  Its  insertion  is  below  the  middle  of  the  depth  of 
the  body  and  below  the  level  of  the  center  of  the  orbit.  Its  tip  does  not  reach  to  the 
perpendicular  from  the  origin  of  the  anal. 

Insertion  of  ventral  behind  pectoral  and  slightly  in  advance  of  the  insertion  of  the  dor- 
sal. Its  distance  from  the  snout  (22)  is  greater  than  twice  its  length  (9).  Its  long  filament 
does  not  reach  to  the  origin  of  the  anal  tin. 

Radial  formula:  D.  11,  80  + ;  A.  76  +  ;  P.  13;  V.  7. 

Color,  silvery  gray.     The  thick,  closely-set  spines  are  matted  with  oozy  mud  which  can

The  type  specimen  (Cat.  No.  26007,  0".  S.  ZsT.  M.),  248  millimeters  in  length,  was  taken  by 
the  Fist  Hawk  September  4,  at  station  S71,  in  40°  02'  54"  N.  hit.,  7(P  23'  40"  W.  Ion.,  al  a 
depth  of  115  fathoms.  It  is  very  similarto  Lowe's Maorurus  atlanticus,  and  but  forGiinther's 
opinion  that  they  are  distinct,  on  account  of  the  larger  spines  on  the  scales,  ye  should 
have  placed  our  specimens  in  that  species. 

Numerous  specimens  have  been  obtained  by  the  American  vessels  jom  115  to  Mil 
fathoms,  and  the  Challenger  also  collected  it  from  the  depths  near  the  Bahamas.  The

A  species  with  an  exceedingly  elongate  snout,  nearly  twice  as  long  as  the  eye,  with  a 
black  flap  between  the  nostrils;  with  the  angle  of  the  month  nearly  reaching  to  the  vertical 
from  the  posterior  margin  of  the  oil  lit ;  the  head  contained  -U  times  in  total  length  and 
equaling  twice  the  greatest  height  of  body.  The  ridge  of  the  head  is  very  strong  and 
continuous  from  the  snout  to  the  angle  of  the  preopercle,  having,  also,  strong  supraocular 
and  occipital  ridges. 

Eye  nearly  round,  its  horizontal  diameter  j  length  of  the  head  and  equal  to  interor- 
bital  space. 

The  ventral  originates  under  the  middle  of  the  first  dorsal,  and  extends  to  the  fourth 
ray  of  the  anal.  The  distance  from  ventral  origin  to  vent  is  contained  3.J  times  in  length 
of  head. 

The  second  spine,  of  the  dorsal  is  weak  and  smooth,  its  length  equal  to  postorbital  part 
of  head,  its  base  slightly  less  than  the  distance  between  first  and  second  dorsals. 

Squamation  excessively  rough,  each  scale  bearing  about  5  large  spines  besides  many 
smaller  ones,  the  median  spine  of  the  large  series  being  much  the  largest.  Five  rows  of 
scales  between  origin  of  dorsal  and  lateral  line,  19  from  vent  forward  to  lateral  liue  and  12 
backward. 

Barbel  one-fourth  as  long  as  snout. 

M.  occa  appears  to  be  a  near  relative  of  C.  atlanticus,  and  is  very  close  also  to  M. 
japonicus  of  Vaillant  (Exp.  Sci.  Travailleur  et  Talisman,  Poissons,  254,  pi.  xxi,  fig.  1), 
identified  by  him,  without  adequate  grounds,  with  M.  japonicus,  Scblegel. 

This  species  has  scales  similar  to  those  of  Macrurus  Fabricii,  there  being  a  strong 
median  keel  formed  by  a  series  of  3  to  5  spines,  of  which  the  last  is  the  largest.  The  surface 
of  each  scale  also  contains  about  4  or  more  lateral  ridges  formed  by  series  of  short  spines. 
In  a  much  larger  example,  No.  37334,  measuring  18  inches  in  length,  the  lateral  series  of 
keels  have  greatly  increased  in  number,  the  individual  spines  have  become  more  prominent, 
so  that  the  median  keel  has  become  less  conspicuous  than  in  the  type.    In  the  larger  spec-

[men  referred  bo  the  nakedness  of  the  under  surface  of  the  head  is  even  more  pronounced 
than  in  the  smaller,  in  which  tlio  under  surface  of  the  head  beneath  t i t < -  suborbital  and  nasal 
ridge  is  almost  entirely  naked.  The.  interm axilla  has  a  very  short  bone  similar  in  structure 
and  dentition  to  that  of  Macrurus  Fabricii,  that  is  to  say.  the  intermaxillary  teeth  are  in  a 
rather  broad  villiform  band,  and  the  outer  teeth  are  not  enlarged.  The  mandibulary  teeth 
are  in  a  similar  broad  villiform  band.  The  mouth  is  entirely  interior  and  small.  The  gill 
membranes  are  attached  across  the  isthmus  and  are  very  little  emargiuate  and  not  deeply 
cleft,  in  the  large  example  the  gill  membrane  is  attached  to  the  isthmus  and  not  deeply 
cleft,  but  there  is  a  very  narrow  l'ree  margin  behind. 

The  gill  rakers  are  very  short,  tubercular,  and  few  in  number,  certainly  not  more 
numerous  than  in  Fabricii.  In  the  large  example  only  8  little  tubercles  can  lie  seen  on  the 
first  gill  arch. 

Second  spine  of  the  dorsal  in  the  type  specimen  is  smooth,  with  the  exception  of  two 
weak  spines  near  its  tip,  but  in  the  large  example  there  is  no  trace  of  serrations  on  the 
dorsal  spine. 

The  type  specimen  (Oat.  No.  37334,  U.  S.  N.  M.),  450  millimeters  in  length,  was  taken 

by  the  Albatross  from  station  SVM\.  in  28°  34'  N.  lat.,  86°  48'  W.  Ion.,  at  a  depth  of  335 

fathoms.

xxn,  121,  note  3. 

A  Ccelorhynchus,  in  general  appearance  resembling  M.  carminatus,  from  which  it  may 
be  quickly  distinguished  by  its  sharper  and  longer  snout,  smaller  scales,  more  advanced 
second  dorsal,  and  many  less  prominent  characters.  The  body  is  normal  in  shape,  its  great  est 
height  (44  millimeters  in  the  type  specimen)  contained  Gi  times  in  its  total  length.  Scales 
moderate,  strong,  densely  covered  with  minute  spines,  -without  enlarged  median  keel,  as  in 
Macrurus  fabricii ;  124  in  the  lateral  line,  0  series  between  origin  of  dorsal  and  lateral  line, 
and  15  or  10  series  from  vent  forward  to  lateral  line.  The  length  of  the  head  (07  milli- 
meters) is  contained  nearly  4i  times  in  the  total  length;  interorbital  area  flat,  its  greatest 
width  (13  millimeters)  about  5  times  in  the  length  of  the  head.  Postorbital  portion  of  head 
(21  millimeters)  contained  about  3  times  in  its  own  length,  and  just  as  long  as  the  eye, 
which  is  oval  (its  horizontal  diameter  21  millimeters),  and  If  as  long  as  its  vertical  diam- 
eter (15  millimeters).  Snout  long,  thin,  diaphanous,  with  acuminate  point,  its  general  form 
resembling  that  of  .1/.  carminatus.  The  nostrils  are  close  to  the  orbit,  the  posterior  ones 
much  the  largest.  Teeth  in  both  jaws  in  villiform  bands,  minute.  Barbel  slender  and 
short,  its  length  (7  millimeters)  one-third  that  of  the  eye.  The  maxillary  extends  to  the  ver- 
tical through  the  middle  of  the  pupil.  Length  of  upper  jaw  (19  millimeters)  slightly  more 
than  3  times  in  length  of  head.  Length  of  mandible  (20  millimeters)  contained  2i  times  in 
length  of  head.  The  intermaxillary  is  a  short  bone  as  compared  with  the  maxillary.  The 
miter  series  of  teeth  in  this  bone  and  the  mandible  not  enlarged,  and  the  teeth  not  becoming 
nniserial.  The  gill  membrane  is  narrowly  attached  to  the  isthmus.  Gill-rakers  minute, 
tubercular,  about  10  on  the  first  arch.  The  suborbital  ridge  is  very  strong,  and  is  contin- 
ued almost  in  a  straight  line  by  the  lateral  ridge  of  the  snout.  The  under  surface  of  the 
head,  except  the  chin  and  branchiostegal  region,  is  densely  covered  with  small,  spiny  tuber- 
cles. There  is  a  naked  space  on  the  under  surface  of  the  snout;  it  occupies  almost  the  entire 
distance  from  the  front  of  the  month  to  the  tip  of  the  snout;  the  space  is  widest  anteriorly, 
l)iit  its  greatest  width  is  only  about  one-fifth  the  length  of  the  snout.  The  intermaxillary 
is  protractile  in  a  nearly  vertical  direction,  and  the  month  is  distinctly  inferior  and  not 
lateral. 

First  dorsal  with  2  spines — the  first  minute,  the  second  smooth,  elongate — and  8 
rays,  the  last  double,  inserted  at  a  distance  from  the  snout  (72  millimeters)  equal  to  one- 
fourth  of  the  total  length;  the  second  spine  (39  millimeters  long)  reaching  the  fifth  ray  of 
the  second  dorsal.  The  length  of  its  base  (15  millimeters)  equal  to  three-quarters  of  the 
space  between  the  two  dorsals.  The  second  dorsal  begins  in  the  perpendicular  from  the

seventh  ray  of  the  anal,  and  at  a  distance  from  the  first  dorsal  (20  millimeters)  about  equal 
to  the  diameter  of  the  eye.  The  longest  rays  are  not  as  long-  as  the  barbel.  It  contains  at 
least  110  rays.  The  anal  is  inserted  under  the  interspace  between  the  two  dorsals;  its 
height  is  equal  to  one-fourth  the  length  of  the  head.  It  contains  at  least  110  rays.  The 
pectoral  is  inserted  in  advance  of  the  origin  of  the  first  dorsal,  its  length  (33  millimeters) 
half  that  of  the  head.  Its  tip  extends  to  the  vertical  from  the  fifth  anal  ray,  and  to  about 
the  seventeenth  scale  of  the  lateral  line.  The  ventral  originates  under  the  second  spine  of 
the  dorsal,  its  outer  ray  somewhat  produced,  extending  slightly  beyond  the  origin  of  the 
anal.    The  distance  of  the  vent  from  the  origin  of  the  ventral  equals  the  length  of  the  eye. 

Color,  silvery  gray,  with  yellowish  and  lavender  tints. 

Many  specimens  were  obtained  by  the  Albatross.  The  type  is  selected  from  a  number

Fig.  A. 

Snout  not  much  produced,  shorter  than  the  eye,  which  is  very  large,  two -fifths  of  the 
length  of  the  head,  its  vertical  diameter  being  considerably  more  than  the  width  of  the  in- 
terorbital  space.  Scales  with  from  8  to  10  subparallel  keels.  Upper  and  lateral  portions 
of  the  head  covered  with  small  rough  scales,  lower  naked.  There  are  four  scales  in  a  trans- 
verse series  between  the  first  dorsal  spine  and  lateral  line;  distance  between  the  two  dor- 
sal fins  equal  to  the  length  of  the  base  of  the  first.  Anterior  dorsal  spine  smooth.  Outer 
ventral  ray  produced  into  a  filament.  Distance  between  the  vent  and  isthmus  shorter  than 
the  head  without  snout.  Barbel  small.  Whitish,  with  broad,  irregular,  blackish  bands 
across  the  back.

The  Challenger  obtained  it  from  stations  305A,  309,  309A,  and  311,  on  the  east  coast  of 
the  southern  extremity  of  South  America,  at  depths  of  125, 10, 140,  and  245  fathoms,  respec- 
tively. 

The  species  is  closely  allied  to  Macrurus  australis,  but  has  (1)  a  narrower  forehead, 
(2)  a  larger  eye,  and  (3)  fewer  keels  on  the  scales.  In  the  smaller  and  youuger  specimens 
the  keels  are  fewer  in  number  (5  to  6)  and  have  a  more  divergent  direction  than  iu  the  larg- 
est example.

shorter  than  the  maxillary.  Teeth  in  villiform  bands  in  both  jaws;  barbel  very  small.  In- 
terorbital  space  convex,  its  width  being  considerably  more  than  the  diameter  of  the  eye, 
which  in  a  specimen  •'!  feet  long  is  equal  to  the  length  of  the  snout  and  one-fourth  of  that

Radial  formula :  J).  10;  P.  19;  V.  7.     (Gunther.) 

Coryphcenoides  rupestris has 4+  15  gill-rakers (=19).  The  gill  membrane  is  entirely  free 
from  the  isthmus  behind.  The  inter  maxilla  is  continued  beyond  its  vertical  process  and 
extends  almost  as  far  back  as  the  maxilla,  these  two  bones  being  about  equal  in  length. 
The  last  third  of  the  intermaxilla  is  toothless.  The  intermaxillary  teeth  are  in  a  very  nar- 
row band,  which  is  uniform  in  width,  and  the  outer  teeth  are  only  slightly  enlarged.  The 
mandible  has  villiform  teeth  in  a  broad  bunch-like  band  at  the  symphysis  and  becoming 
uniserial  behind.  The  eye  is  nearly  circular.  The  snout  projects  slightly.  Gill-rakers 
longer  and  less  tubercular  in  character  than  in  H.  berglax  and  M.  acrolepis.  The  sub- 
orbital ridge  is  feebly  developed  and  is  very  abruptly  curved  upward  and  narrowed  in 
front  of  the  eye  where  it  joins  the  nasal  ridge.  In  M.  berglax  and  M.  acrolepis  the  sub- 
orbital ridge  is  very  strong  and  is  continued  almost  in  a  straight  line  towards  the  nasal  ridge. 

Specimens  of  this  tish  were  taken  by  the  Porcupine  and  Knight  Errant  between  Shet- 
land and  the  Faroes  in  200-500  fathoms.  A  single  specimen  was  secured  by  the  Blake  from

Challenger  Report,  xxil,  1887,  139. 

The  snout  is  acute,  projecting  beyond  the  mouth,  its  tip  at  a  distance  from  the  mouth 
equal  to  or  greater  than  the  diameter  of  the  eye.  The  bones  of  the  head  are  very  soft  and 
flexible,  and  its  surface  is  very  irregular,  there  being  a  very  prominent  subocular  ridge,  a 
prominent  ridge  extending  lroin  the  tip  of  the  snout  to  the  middle  of  the  interorbital  space, 
and  a  curved  ridge  extending  from  the  upper  anterior  margin  of  the  orbit  over  the  cavity 
containing  the  nostrils  to  a  prominent  point  at  the  side  of  and  slightly  posterior  to  the  tip 
of  the  snout.  The  barbel  is  two-thirds  as  long  as  the  eye.  The  eye  is  contained  in  the  head 
4  times,  and  the  length  of  the  head  in  the  total  length  <!  times. 

The  interorbital  space  is  almost  twice  the  diameter  of  the  eye,  and  is  equal  to  the  length 
of  the  upper  jaw.     The  preoperculum  is  crenulate. 

The  upper  jaw  extends  to  the  vertical  through  the  posterior  margin  of  the  pupil;  its

length  equals  half  thai  of  the  head  without  the  snout.  The  mandible  extends  behind  the 
vertical  through  the  posterior  margin  of  the  orbit;  its  length  is  contained  ■'!  times  in 
the  distance  from  the  tip  of  the  snoul  to  the  origin  of  the  firsl  dorsal.  The  teeth  are  in 
villil'onn  bands  in  intermaxillary  and  mandible;  the  mandibular?  scries  oniserial  in  about 
the  second  half  of  its  length. 

The  first  ray  of  the  dorsal  is  very  short;  the  second  compressed  anteriorly  ami  ser 
rated,  with  slender  teeth  closely  appressed  and  bent  upwards.  Its  length  is  equal  to  the 
length  of  the  head  and  is  greater  than  the  height  of  the  body.    This  tin  is  seated  upon  a 

humplike  elevation  of  the  back,  and  its  base  is  as  long  as  the  snout.  The  second  dorsal 
begins  over  the  tenth  or  twelfth  anal  ray.  and  at  a  distance  from  the  end  of  the  firsl  dorsal 
equal  to  the  length  of  the  head  without  the  snout.  The  vent  is  located  not  tar  behind  the 
vertical  from  the  end  of  the  lirst  dorsal. 

Scales  22  to  24  in  a  transverse  series  (the  position  of  the  lateral  line  can  not  be  deter- 
mined, but  there  appear  to  be4aboveit);  the  scales  are  oval,  membranaceous,  showing 
several  parallel  ridges  composed  of  . small  spines  and  rather  large,  Gill  membrane  very 
deeply  cleft  and  attached  to  the  isthmus.  Gill-rakers  short  and  stout,  about  11  below 
the  angle  on  the  first  arch.

Ion.,  at  a  depth  of  1,002  fathoms.  .Most  of  these  had  their  tails  broken  off,  and  all  of 
them  were  completely  denuded  of  scales;  a  natural  consequence  of  their  passage  in  the  nets 
from  the  ocean  depths.  By  a  happy  chance  two  scales  were  found  attached  to  the  base  of 
the  dorsal  tin  of  one  of  the  larger  individuals,  thus  enabling  us  to  determine  the  general 
character  of  the  covering  of  the  body.

Head  deeper  than  broad,  with  vertical  sides  and  wide  nmciferous  cavities;  snout 
obtuse,  short,  slightly  projecting  beyond  the  mouth,  the  cleft  of  which  is  oblique,  anterior 
and  lateral,  and  extending  to  behind  the  middle  of  the  eye.  Teeth  in  both  jaws  minute, 
of  equal  size,  villiform,  in  narrow  bands.  Barbel  small.  Interorbital  space  as  wide  as  the 
eye,  the  diameter  of  which  is  one-third  of  the  length  of  the  head,  and  exceeding  the  snout 
in  length.  Scales  extremely  thin,  deciduous,  spiny,  of  comparatively  large  size.  Preoper- 
cular  margin  not  serrated.  Anterior  dorsal  spine  smooth,  filamentous;  the  distance 
between  the  two  dorsal  fins  is  but  little  more  than  the  length  of  the  base  of  the  former. 
Pectoral  fin  about  half  as  long  as  the  head.  Vent  far  behind  first  dorsal  but  close  to  the

GUnther,  who  examined  a  young  specimen  from  Nice,  5J  inches  long,  says  that  there 
can  be  no  doubt  that  this  is  a  juvenile  form,  and  that  if  it  were  not  for  the  dentition  he 
should  not  hesitate  to  refer  it  to  Macrurus  Icevis,  with  which  it  agrees  in  several  important 
characters.  Moreau  and  Vaillant  had  no  opportunity  to  examine  larger  specimens.  The 
French  expedition  obtained  118  specimens  at  depths  of  265  aud  1,042  fathoms  oft' the  coast 
of  Morocco.

Macrurua  Qoodii,  Gunther,  Challenger  Ri-port.  xxn,  INST,  13*;. 
llijmenorephahia  Goodei,  BEAN,  MS. 

The  relations  of  this  species  appear  to  be  with  .1/.  Bairdii,  from  which  it  differs  in  (1) 
its  longer  snout,  (2)  the  locution  of  the  vent,  which  is  much  farther  back,  and  (3)  the  absence 
of  keels  upon  any  of  its  scales. 

The  length  of  the  specimen  described  is  :>22  millimeters.  The  body  is  much  stouter 
than  in  .1/.  Bairdii,  its  greatest  height  being  contained  6J  times  in  its  length.  The  scales 
are  small,  strong,  the  free  portions  covered  by  series  of  small  vitreous  spines  arranged  in 
about  six  rows;  there  is  no  specialization  of  the  central  row,  as  in  .1/.  Bairdii,  though  the 
median  spine  at  the  margin  of  the  scale  projects  most  strongly  aud  is  longest,  consisting  of 
7  or  8  spines.  The  number  of  scales  in  the  lateral  line  is  about  the  same,  there  being  about 
150;  there  are  7  above  and  18  below  the  line. 

Length  of  head  contained  5§  times  in  total  length.  Width  of  interorbital  area  a  little 
greater  than  horizontal  diameter  of  orbit  and  length  of  operculum,  and  contained  4 \  times 
in  the  length  of  the  head.  Length  of  snout  about  equal  to  width  of  interorbital  space  and 
about  one-half  the  postorbital  portion  of  the  head.  Snout  triangular,  depressed,  its  tip  in 
the  axis  of  the  body,  and  nearly  on  a  level  with  the  lower  margin  of  the  eye;  its  lower  sur- 
face forming  an  angle  with  the  body  axis,  about  equal  to  that  formed  with  same  by  its 
upper  profile.  The  superior  ridge  is  pronounced  anteriorly,  but  ends  in  advance  of  the  con- 
cavity in  the  interorbital  space.  The  lateral  ridges  are  prominent,  and  continue  posteriorly 
to  the  eye,  with  strong  angular  projections  in  front  of  the  nostrils.  No  ridges  continued  from 
supraorbital  region.  Nostrils  rather  close  to  the  eye.  Barbel  shorter  than  the  eye.  Tip 
of  lower  jaw  under  anterior  nostril;  cleft  of  mouth  under  posterior  margin  of  orbit.  The 
under  surface  of  the  head  is  naked,  with  the  exception  of  a  few  minute,  spiny  tubercles  on 
the  under  surface  of  the  mandible.  The  suborbital  ridge  is  very  slightly  developed.  The 
intermaxillary  is  a  long  bone,  nearly  as  long  as  the  maxillary,  and  the  mouth  is  large.  The 
teeth  on  the  intermaxillary  are  in  a  double  series,  of  which  the  outer  contains  much  larger 
teeth  than  the  iuuer.  The  teeth  in  the  inaudible  are  uniserial;  the  dorsal  spine  is  strongly 
serrated. 

Distance  of  first  dorsal  from  snout  equal  to  nearly  4  times  the  length  of  its  base,  its 
distance  from  the  anterior  margin  of  the  orbit  equal  to  the  length  of  the  head.  First  spine 
minute;  second  spine  strongly  serrated  as  in  M.  Bairdii,  nearly  two-thirds  the  length  of 
the  head,  and  when  laid  down  is  far  from  reaching  to  the  origin  of  the  second  dorsal. 
When  the  fin  is  erect,  its  superior  margin  is  nearly  at  right  angles  to  the  plane  of  the  back, 
aud  slightly  convex.  The  distance  between  the  two  dorsals  is  twice  the  length  of  the  base 
of  the  first,  the  second  beginning  in  the  perpendicular  from  the  fifth  ray  of  the  anal. 

The  anal  is  about  3  times  as  high  as  the  second  dorsal.  The  vent  is  under  the  thirtieth 
scale  of  the  lateral  line  directly  in  advance  of  the  anal,  and  at  a  distance  from  the  ventral 
considerably  greater  than  the  length  of  that  fin,  in  this  respect  differing  widely  from  M. 
Bairdii. 

Distance  of  pectoral  from  snout  slightly  more  than  the.  length  of  the  head.  Its  length 
is  less  than  that  of  the  dorsal  spine,  and  slightly  more  than  half  its  distance  from  the  snout. 
Its  insertion  (upper  axil)  is  in  the  middle  line  of  the  body. 

Insertion  of  ventral  under  that  of  pectoral,  aud  slightly  in  advance  of  that  of  dorsal. 
Its  first  ray  is  not.  greatly  prolonged,  and  is  about  half  as  long  as  the  distance  of  the  tin 
from  the  snout. 

The  branchiostegal  membrane  is  narrowly  attached  to  the  isthmus,  leaving  no  free 
margin  behind.  The  gill-rakers  are  very  small  tubercles,  and  there  are  only  ten  below  the 
angle  on  the  first  arch. 

Radial  formula:   1st  D.  n.  8-9j  2nd  I).  105;   A.  110;  V.  20;   V.  10;  scales  7/150/18. 

Color  dark  reddish  brown,  the  spines  upon  the  scales  with  a  metallic  luster.  The  young 
have  3  stellate  bosses  upon  the  snout,  one  :it   its  tip,  one  at  some  distance  upon  each  side.

This  species  belongs  in  the  subgenus  Xewafmntrus  of  Giinther.  It  resembles  Macrurus 
affinis,  from  -which  it  differs  in  its  smaller  eye  (one- fifth  as  long  as  the  head),  and  in  having 
the  head  contained  5§  times  in  the  total  length,  instead  of  5  times  as  in  affinis.

xxii.  1887,  156. 

Body  stoutish,  its  greatest  height  (23  millimeters)  contained  7  times  in  total  length. 

The  scales  are  moderate,  deciduous,  cycloid,  with  no  visible  armature,  about  8  rows 
under  the  base  of  the  first  dorsal. 

Length  of  head  (28  millimeters)  about  6  in  total  length.  The  bones  of  the  head  are 
very  soft  and  cavernous,  in  many  places  without  muscular  covering,  spongy.  Interorbital 
area  doubly  concave  with  a  spinous  medial  ridge;  its  greatest  width  (10  millimeters)  about 
2|  in  the  length  of  the  head. 

Postorbital  portion  of  head  (13  millimeters)  about  half  its  length,  1£  as  long  as  eye. 
which  is  circular,  its  diameter  (10  millimeters)  contained  2i  times  in  the  length  of  the  head. 

Snout  broad,  very  obtuse,  its  width  at  nostril  nearly  equal  to  interorbital  width,  its 
length  (6  millimeters)  4§  times  in  that  of  the  head.     Nostrils  normal. 

Teeth  in  both  jaws  in  villifbrm  bands,  very  small;  a  naked  space  at  the  symphysis  of 
of  the  intermaxillary';  vomer  and  palatine  toothless.  Gill-rakers  very  short,  minute,  and 
rather  numerous;  about  18  below  the  angle  of  the  anterior  arch.  Pseudobrauchia-  absent. 
Barbel  two  fifths  as  long  as  the  eye. 

First  dorsal  composed  of  2  spines,  the  first  of  which  is  minute,  inserted  at  a  distance 
from  the  snout  (2S  millimeters)  equal  to  the  length  of  the  head;  the  second  as  long  as  the 
head  without  the  snout,  and  10  branched  rays:  its  base  (111  millimeters)  equal  to  diameter 
of  eye.  Second  dorsal  almost  rudimentary,  its  rays  remarkably  short,  about  133  in  num- 
ber; its  distance  from  the  first  dorsal  half  the  length  of  head. 

Anal  much  higher  than  second  dorsal,  its  distance  from  the  snout  (46  millimeters)  con- 
tained about  3 A  times  in  the  total  length.  About  27  rays  in  a  space  equal  to  length  of 
head.     Anterior  rays  longest,  in  length  about  three  fourths  of  the  diameter  of  the  eye. 

Pectoral  inserted  under  the  first  branched  ray  of  the  first  dorsal,  its  length  (20  milli 
meters)  equal  to  twice  that  of  the  eye  and  about  two-thirds  length  of  head. 

Ventral  slightly  behind  the  pectoral,  its  first  ray  filamentous,  reaching  to  the  base  of 
the  tenth  anal  ray;  it  consists  of  11  rays. 

Color,  gray,  with  silvery  tints  on  sides:  the  abdomen  and  lips  dark. 

Dr.  Bean  has  reexamined  the  types  of  Bothy gadus  cavernosus^  and  is  convinced  that 
Dr.  Giinther  is  probably-  right  in  his  statement  that  it  belongs  to  the  subgenus  Mysta- 
conurus,  but  since  the  specimens  are  all  young  and  have  more  rays  in  the  ventral  fin 
than  the  described  species,  it  can  not  be  referred  to  M.  longifilis,  and  must  be  called  for  the 
present  Hymenocephalus  cavernosus. 

The  following  revised  data  are  presented:  D.  n,  10, 133;  A.  27  rays  in  space  equal  to

Snout  considerably  projecting  beyond  the  mouth,  pointed  in  the  middle;  it  is  twice  as 
long  as  the  eye.  which  is  unusually  small,  only  half  as  wide  as  the  interorbital  space. 
Mouth  rather  wide,  extending  beyond  the  center  of  the  eye.  Upper  teeth  villiform,  in  a 
very  narrow  band,  those  of  the  inaudible  very  small,  biserial.  Barbel  minute.  Praeoper- 
eulum  with  the  angle  produced  backwards,  broadly  rounded  and  crenulated  on  the  margin. 
The  terminal  portion  of  the  tail  is  prolonged  into  a  long  filament,  more  slender  than  in

The.  Challenger  obtained  this  species  from  the  Antarctic  Ocean  and  from  the  deep  sea 
on  both  sides  of  the  South  American  Continent:  from  station  325,  at  a  depth  of  2,650 
fathoms;  from  station  323,  at  a  depth  of  1,900  fathoms:  from  station  299,  at  a  depth  of  2,160 
fathoms;  from  station  158,  at  a  depth  of  1,800  fathoms;  from  station  l.">7,  at  a  depth  of  1,950 
fathoms,  and  from  station  146,  at  a  depth  of  1,375  fathoms. 

Dr.  Giinther  holds  that  this  species  is  clearly  one  of  those  of  the  family  which  extend  to 
the  greatest  depths,  since  the  small  eye,  the  soft  bones,  the  lack  of  firmness  in  the  scales, 
and  the  filamentous  tail  indicate  its  abyssal  abode. 

TRACHONURUS,  Giinther. 
Trackonurus  (as  subgenus),  GCnther,  Challenger  Report,  xxn.  1887,  124. 

A  genus  resembling  Macrurus  in  form  and  dentition,  but  with  incomplete  squamation, 
the  skin  being  densely  studded  with  elect  spines,  strongest  at  the  bases  of  the  vertical 
fins,  space  between  the  vent  and  ventral  scaleless;  snout  short,  compressed;  interorbital 
ridge  obsolete;  mouth  small,  lateral.

Maamrus  ( Malacoeephalus)  sulcatus,  Gunther.  Challenger  Report,  xxn,  1887,  169. 

The  type  of  this  species,  Cat.  No.  37335,  is  an  individual  23S  millimeters  long,  taken  at 
Albatross  station  2394,  in  420  fathoms,  with  a  large  specimen  (about  350  millimeters)  badly 
mutilated,  from  Blake  station  lxxiii,  oft'  Martinique,  472  fathoms,  as  a  collateral  type. 

Body  is  elongate,  rapidly  contracted  behind  the  abdomen,  the  tail  long  and  whip-like; 
greatest  height  of  body  (25  millimeters)  9.J  times  in  total  length. 

Scales  moderate,  strongly  armed,  each  with  8-10  spinelets,  irregularly  placed,  the 
spinelets  less  numerous  in  the  young,  which  feel  bristly  to  the  touch,  separated  by  wide, 
deep  fmrows  (hence  the  specific  name);  more  than  175  in  the  lateral  line.  Between  origin 
of  dorsal  fin  and  lateral  line  7;  counting  from  the  origin  of  the  lateral  line  the  number  of 
scales  in  a  distance  equal  to  length  of  head  is  33.  Between  the  anal  and  vent  21-22 
(counting  forward  from  vent,  10  counting  backward). 

Armature  of  head  similar  to  that  of  body,  but  the  scales  upon  the  snout,  cheeks,  and 
chin  have  very  feeble  spines. 

Length  of  head  (32  millimeters)  1\  times  in  total  length. 

Iuterorbital  area  nearly  tlat,  its  length  (10  millimeters)  equal  to  diameter  of  eye,  and  a 
little  less  than  one-third  length  of  head.  Postorbital  portion  of  head  (15  millimeters)  U 
times  as  long  as  diameter  of  eye.  Eye  circular,  in  larger  individual  its  diameter  less  than 
width  of  iuterorbital  space,  3§  times  in  length  of  head.  Snout  short,  obtuse,  scarcely  over- 
hanging the  mouth,  its  length  (7  millimeters)  4i  times  in  that  of  head;  in  the  larger  indi- 
vidual it  is  4J  times  in  length  of  head. 

Nostrils  somewhat  above  level  of  middle  of  eye,  the  anterior  one  nearly  upon  the 
dorsal  outline. 

Teeth,  two  series  in  upper  jaw  in  villiform  bands,  in  the  outer  series  slightly  enlarged; 
in  lower  jaw  in  a  single  series. 

The  end  of  the  maxilla  reaches  to  the  vertical  through  the  hind  margin  of  pupil  in  the 
large  specimen,  to  that  through  the  front  margin  of  the  same  in  the  type.  Length  of  upper 
jaw,  including  maxilla  (11  millimeters),  about  3  times  in  length  of  head.  Length  of  man- 
dible (13  millimeters)  equal  to  one-half  the  height  of  the  body.  Barbel  (4  millimeters)  2.J 
times  in  diameter  of  eye;  in  the  large  specimen  it  is  half  as  long  as  the  eye. 

Gill-rakers  very  small,  tubercular,  almost  rudimentary,  about  10  below  angle  of  first 
arch;  the  attachment  of  the  membrane  to  the  first  arch  is  very  extensive,  but  the  mem- 
branes are  tree  from  the  isthmus.     Pseudobranchise  absent. 

First  dorsal  comparatively  low,  composed  of  2  spines,  the  first  rudimentary,  the  second 
elongate  and  smooth,  and  8-9  rays.  Its  insertion  is  immediately  over  that  of  the  pectoral; 
its  distance  from  the  snout  (30  millimeters)  equals  1£  times  the  length  of  the  head;  its  length 
of  base  (7  millimeters)  equal  to  length  of  snout.  Its  longest  spine,  when  laid  backward 
reaches  beyond  origin  of  second  dorsal,  its  length  (15  millimeters)  oue-half  to  two-thirds 
that  of  the  head. 

Second  dorsal  very  low;  its  distance  from  first  dorsal  equal  to  one-third  length  of 
head ;  in  the  type  about  one-fourth. 

Anal  much  higher  than  second  dorsal,  yet  very  low,  its  longest  ray  equal  in  length  to 
diameter  of  eye;  its  distance  from  snout  (51  millimeters)  4§  times  in  total  length,  its  origin 
being  nearly  under  that  of  the  second  dorsal. 

Pectoral  inserted  under  origin  of  first  dorsal,  its  length  about  i  that  of  head. 

Ventral  inserted  behind  the  vertical  from  the  end  of  the  base  of  the  first  dorsal  in  the 
type.  In  the  mutilated  larger  specimen  it  appears  to  be  under  the  posterior  ray  of  the  first 
dorsal.  The  ventral  extends  to  the  origin  of  the  anal,  its  length  (10  millimeters)  equaling 
diameter  of  eye;  in  large  specimen  1J  diameter  of  eye.  Vent  about  midway  between  origin 
of  ventrals  and  anal.

We  protesl  against  the  action  of  English  ichthyologists  in  changing  the  form  of  the 
generic  name.     It  is  properly  and  legitimately  formed  from  XHXtvoq  (a  thong),  and  dopa  (tail). 

Chalinura  fernandezianus,  G-iinther  (Challenger  Report,  xxn.  145,  pi.  xxxvin,  tig.  B) 
was  obtained  by  the  Challenger  at  station  300,  south  of  Juan  Fernandez,  in  1,375  fathoms. 

Ghalinura  liocephala,  Giinther  (loc.  cit.,  145,  pi.  xxxvm,  fig.  A)  was  taken  by  the 
Challenger  off  Japan,  in  1,875  fathoms,  and  in  mid  Pacific  in  2,050  fathoms. 

Chalinura  Murrayi,  Giinther  (loc.  cit.,  140,  pi.  xxxiv,  fig.  A)  was  taken  by  the  Challenger

Chalinura  serrula,  Bean  (Proc.  U.  S.  Nat.  Mus.,  xin  (No.  795),  37)  was  taken  by  the 
Albatross  east  of  Prince  of  Wales  Island,  in  1,569  fathoms.

[faerurns  sirnulus,  Gcxtiiei:,  Challenger  Report,  xxn,  1887,  143. 

The  most  salient  characters  are  (1)  the  very  large  mouth,  (2)  the  long  obtuse  snout,  and 
(3)  the  very  elongate  first  ventral  ray. 

The  body  is  shaped  much  as  in  Coryphwnoides,  but  is  rather  stout,  its  greatest  height 
being  contained  6  times  in  its  total  length.  The  back  is  somewhat  gibbous  in  profile,  the 
dorsal  outline  rising  quite  rapidly  from  the.  interorbital  region  to  the  origin  of  the  first 
dorsal,  whence  it  descends  almost  in  a  straight  line  to  the  end  of  the  tail. 

The  scales  are  rather  small,  but  with  indications,  particularly  on  the  head,  of  radiating 
stria'.  The  number  of  scales  in  the  lateral  line  is  about  150;  about  8  rows  between  the  origin 
of  the  dorsal  and  the  lateral  line,  and  17  to  10  between  that  line  and  the  origin  of  the  anal. 

Tlie  length  of  the  head  is  contained  about  5  times  in  the  total  length  of  the  body.  The 
width  of  the  interorbital  area  is  much  greater  than  the  long  diameter  of  the  orbit,  which  is 
nearly  twice  that  of  the  snout.  The  postorbital  portion  of  the  head  is  about  three  times  as 
long  as  the  diameter  of  the  eye.  The  length  of  the  operculum  is  equal  to  hall'  that  of  the 
upper  jaw.  The  preoperculum  is  emarginate  on  its  posterior  limb.  The  orbit  is  nearly 
round,  its  diameter  contained  G  times  in  the  length  of  the  head.  The  snout  is  broad,  obtuse, 
scarcely  projecting  beyond  the  mouth:  its  width  nearly  as  great  at  the  tip  as  that  of  the 
interorbital  space  or  as  its  own  length.  The  median  ridge  is  very  prominent,  gibbous  in 
outline  when  observed  laterally;  the  lateral  ridges  start  out  almost  at  a  right  angle  with 
the  median  ridge,  and  are  not  continued  upon  the  sides  of  the  head.  The  suborbitals  prom- 
inent, forming  broad  subocular  ridges.  No  supraorbital  ridges.  Nostrils  in  front  of  the 
middle  of  the  eye,  and  nearer  to  its  anterior  margin  than  to  the  tip  of  the  snout.  Barbel 
longer  than  the  diameter  of  the  eye. 

Teeth  in  the  upper  jaw  in  a  broad  villiform  band,  with  the  outer  series  very  much 
enlarged.    The  lower  jaw  with  the  teeth  in  a  single  series. 

Distance  of  first  dorsal  from  snout  4i  times  the  length  of  its  base,  its  distance  from  the 
anterior  margin  of  the  orbit  about  equal  to  the  length  of  the  head.  First  spine  very  short, 
second  rather  stout  and  with  a  simple  serration  anteriorly,  the  serrae  closely  appressed 
to  the  spine;   its  length  two-thirds  that  of  head. 

The  second  dorsal  begins  at  a  distance  from  the  first  about  equal  to  the  length  of  the, 
upper  jaw. 

The  anal  is  high,  its  average  rays  being  about  three  times  as  long  as  those  in  the 
dorsal.  It  is  inserted  slightly  behind  the  perpendicular  from  the  last  ray  of  the  first 
dorsal.  The  pectoral  is  inserted  over  the  base  of  the  ventral  (its  rays  are  mutilated).  The 
ventral  is  inserted  almost  under  the  pectoral,  but  very  slightly  in  advance;  its  distance 
from  the  snout  is  less  than  the  length  of  its  longest  ray,  which  is  prolonged  in  a  filament 
which  extends  to  the  base  of  the  eighteenth  ray  of  the  anal  fin.

The  length  of  the  specimen  described  is  .'!45  millimeters.  It  is  almost  entirely  denuded 
of  scales;  those  that  remain  have  about  six  longitudinal  ridges  composed  of  small  spines  as 
in  the  species  of  Macrurus.  The  first  gill  opening  also  is  restricted  as  in  Macrurus.  The 
teeth  of  the  upper  jaw  are  in  a  villiform  band  with  the  outer  series  enlarged.  Mandibulary 
teeth  uniserial. 

The  greatest  height  of  the  body  (54  millimeters)  equals  the  length  of  the  head  without 
the  snout.  The  length  of  the  intermaxilla  is  one-third  the  length  of  the  head.  The  maxilla 
extends  to  below  the  hind  margin  of  the  orbit.  The  length  of  the  mandible  is  nearly  one 
half  that  of  the  head,  whieh  is  68  millimeters  long,  being  about  one-fifth  of  the  the  total 
length.  The  barbel  (S  millimeters)  is  two-thirds  as  long  as  the  eye  and  one-half  as  long  as 
the  snout.  The  length  of  the  eye  (11  millimeters)  is  one-sixth  the  length  of  the  head,  and 
one-half  the  width  of  the  interorbital  space. 

The  second  spine  of  the  dorsal  (42  millimeters)  equals  the  length  of  the  postorbital 
part  of  the  head.  The  ventral  when  extended  reaches  to  the  sixth  ray  of  the  anal.  The 
distance  from  the  ventral  to  the  vent  equals  one-half  the  length  of  the  head.  The  length  of 
the  pectoral  equals  the  postorbital  part  of  the  head. 

D.  II,  8;  the  first  31  rays  of  the  second  dorsal  occupy  a  space  equal  to  the  length  of  the

anal  rays  are  nearly  half  as  long  as  the  pectoral. 

The  interspace  between  the  first  and  second  dorsals  is  one-half  of  the  interorbital  part 
of  the  head.     Ventral  9.     Scales  S— 140.

CHALINURA  OCCIDENTALS,  Goode  and  Bean. 

Malacocephaliia  oecidenlalis,  Goode  and  Bean,  Proc.  U.  S.  Nat.  Mus.,  \  in,  1SS5,  597. — GOntheR,  Challenger 
Report,  wii,  1887,  134,  note. 

A  species  which  in  general  appearance  and  proportions  resembles  Malacocephalus 
larois,  Giinther.     Anal  fin  commencing  at  a  distance  behind   the  vent  equal  to  the  length 

of  the  snout,  its  distance  from  the  origin  of  the  ventrals  being  less  than  the  distance  from 
the  origin  of  the  anal,  which  is  distinctly  behind  the  vertical  through  the  posterior  end  of 
the  first  dorsal.     The  ventrals  originate  under  the  middle  of  the  first  dorsal,  ami  the  pec 
torals  under  its  origin.     The   ventral  extends  to,  or  slightly  beyond,  the  anal  origin.     The 
pectoral  is  as  long  as  the  head  without  its  postorbital  part.     The  diameter  of  the  eye  is

contained  2£  times  in  the  length  of  the  head.  The  barbel  is  slightly  longer  than  the  eye. 
The  snout  is  one-quarter  as  long  as  the  head  and  equal  to  the  interorbital  space. 

It  differs  also  in  the  serrature  of  the  second  dorsal  spine,  and  its  length,  which  is 
nearly  equal  to,  if  not  longer  than  the  head.  In  onr  mutilated  specimens  the  first  branched 
ray  is  nearly  as  long  as  the  head.  The  gill  rakers  are  rudimentary,  there  being  11  below 
the  angle  of  the  first  arch. 

The  types  of  this  species  are  small  and  in  very  bad  condition,  making  it  difficult  to 
determine  the  dentition  with  certainty,  but  the  intermaxilla  has  an  outer  series  of  enlarged 
teeth  and  behind  a  villiform  band  <if  smaller  teeth.  The  mandibulary  teeth  are  uniserial, 
all  small  and  unequal  in  size.  The  gill  membrane  is  attached  to  the  isthmus,  but  has  a 
narrow,  free  margin  behind.  The  scales  are  studded  with  minute  spines,  but  have  no 
median  keel.  The  intermaxilla  is  protractile  almost  in  a  vertical  direction ;  it  is  a  'oug 
bone,  being  continued  beyond  the  vertical  expansion. 

D.  i,  10;  the  long  second  ray  coarsely  serrated. 

A  single  specimen,  141  millimeters  in  length,  was  obtained  by  the  Blake  from  station 
lxxxiii,  off  Granada,  at  a  depth  of  1G4  fathoms.  The  Albatross  seemed  an  individual 
from  station  2474,  in  44°  28'  30"  X.  lat..  57°  10'  45"  W.  Ion.,  at  a  depth  of  133  fathoms;

Head  compressed.  The  snout  is  rather  long,  but  its  front  projects  but  slightly  beyond 
the  mouth,  which  is  almost  anterior.  The  eye  is  comparatively  small,  rather  more  than 
one-half  the  length  of  the  snout,  or  one-seventh  the  length  of  the  head  and  three  lift  lis  the 
width  of  the  interorbital  space.  -Mouth  wide,  lateral,  extending  to  below  the  hind  margin 
of  the  eye.  The  teeth  of  the  outer  series  of  the  upper  jaw  are  widely  set  and  much  stronger 
than  those  of  the  villiform  baud.  Mandibulary  teeth  in  a  single  series.  Barbel  as  long  as 
the  eye.  The  preoperculum  with  the  hind  margin  excised,  and  with  the  angle  rounded 
and  produced  backwards,  naked ;  its  lower  margin  is  not  toothed. 

Scales  thiu  and  deciduous;  most  with  5  or  7  radiating  keels,  some,  especially  on  the  back, 
nearly  or  quite  smooth.  There  are  7  scales  in  a  transverse  series  between  the  first  dorsal 
and  the  lateral  line.  Those  on  the  gill-cover  and  in  front  of  the  ventral  fins  are  quite 
smooth;  the  front  part  of  the  snout  and  the  lower  half  of  the  infraorbital  region  scaleless. 
Second  dorsal  spine  slightly  produced,  with  barbs  in  front,  which  are  rather  distantly 
arranged.  The  second  dorsal  fin  commences  at  a  short  distance  behind  the  first.  The  outer 
ventral  ray  produced  into  a  long  filament.  Distance  between  vent  and  isthmus  equal  to 
the  length  of  the  head.

A  single  specimen  was  obtained  by  the  Challeng<  r  off  the  coast  of  BrazU  in  350  fathoms. 

OPTONURUS,  GOnther. 

Optonurus  (as  subgenus),  GOnther,  Challenger  Report,  xxn,  117. 

A  genus  or  subgenus  of  Macruridce,  distinguished  from  Chalinura  chiefly  by  the  absence 
of  denticulations  from  the  first  dorsal  spine.  The  only  species  assigned  by  GHinther  to  this 
group  is  O.  (lenticutatus  (Richardson),  which  occurs  in  moderately  deep  water  off  the  coasts 
of  South  Australia  and  New  Zealand.  The  Challenger  obtained  it  off  New  Zealand  at  a 
depth  of  275  fathoms,  and  off  the  Kermadecs,  in  520  fathoms.

The  Macrurus  macrochir  assigned  here  by  Dr.  Giinther  does  not  appear  to  us  to  lie  con- 
generic with  Malacocephalus  (a  vis.  We  have  therefore  proposed  for  it  a  new  genus  under

Head  compressed,  with  vertical  sides;  muciferous  cavities  wide.  .Snout  obtusely  coni- 
cal, slightly  projecting  beyond  the  month,  the  cleft  of  which  is  oblique,  anterior  and  lateral, 
and  extending  somewhat  behind  the  middle  of  the  eye.  Teeth  of  the  upper  jaw  biserial, 
those  of  the  outer  series  much  stronger  than  the  inner;  mandibulary  teeth  uniserial.  Bar- 
bel shorter  than  the  eye.  The  interorbital  space  flat,  its  width  being  equal  to  or  less  than 
the  diameter  of  the  eye.  which  is  large,  longer  than  the  snout,  and  one-third  or  two-sevenths 
of  the  length  of  the  head.  Scales  very  small,  much  deeper  than  long,  covered  with  short 
minute  bristles.  Praeoperculum  with  the  posterior  margin  slightly  excised  above  the  angle, 
and  with  the  lower  margin  not  serrated.  The  entire  head  is  covered  with  minute,  rough 
scales.  Anterior  dorsal  spine  smooth.  Pectoral  flu  about  two-thirds  of  the  length  of  the 
head.  The  vent  (Fig.  b)  is  close  to  the  root  of  the  ventrals,  which  reach  beyond  it;  it  lies 
at  the  end  of  an  oval  scaleless  depression,  and  there  is  another  triangular  scaleless  space 
between  the  roots  of  the  ventrals.  Distance  between  the  vent  and  the  isthmus  two  thirds

The  type,  1*»  inches  long,  obtained  by  Lowe  at  Madeira,  is  in  the  British  Museum,  where 
it  was  examined  by  us  in  1883.  Liitken  has  found  the  species  on  the  coast  of  Denmark, 
and  Giinther  records  its  capture  southwest  of  Ireland  in  250  fathoms  and  in  the  Medi- 
terranean. The  Challenger  obtained  a  single  specimen  off  the  coast  of  Pernambuco  (station 
122)  in  350  fathoms.  The  Investigator  obtained  a  form  supposed  by  Alcock  to  be  identical 
with  this  in  the  Andaman  Sea  in  265  fathoms,  and  in  the  Laccadive  Sea  in  188-220  fathoms. 
It  has  not  yet  been  observed  in  the  northwestern  Atlantic.

the  length  of  the  snout,  its  distance  from  the  origin  of  the  ventrals  being  less  than  the 
distance  from  the  origin  of  the  anal,  which  is  distinctly  behind  the  vertical  through  the 
posterior  end  of  the  first  dorsal. 

The  ventrals  originate  under  the  middle  of  the  first  dorsal,  and  the  pectorals  under 
its  origin.  The  ventral  extends  to,  or  slightly  beyond,  the  anal  origin.  The  pectoral  is  as 
long  as  the  head  without  its  postorbital  part.  The  diameter  of  the  eye  is  contained  2\ 
times  in  the  length  of  the  head.  The  barbel  is  slightly  longer  than  the  eye.  The  snout  is 
|  as  long  as  the  head  and  equal  to  the  iuterorbital  space. 

It  differs  also  iu  the  serratiue  of  the  second  dorsal  spine,  and  its  length,  which  is 
nearly  equal  to,  if  not  longer  than,  the  head.  In  our  mutilated  specimens  the  first 
branched  ray  is  nearly  as  long  as  the  head.  The  gill-rakers  are  rudimentary,  there  being 
11  below  the  angle  of  the  arch.

Macrurid  fishes,  with  comparatively  short,  thick,  fusiform  body;  short,  globular  head; 
very  obtusely  rounded  snout,  and  with  eye  close  to  profile.  Moutli  entirely  inferior,  but 
not  far  from  tip  of  snout.  Teeth  uniserial  in  the  jaws.  Branchial  opening  very  wide,  the 
brauchiostegal  membrane  adhering  slightly  (in  N.  gigas)  to  the  isthmus.  Head  entirely 
covered  with  large  spinigerous  scales,  like  those  upon  the  body.  Muciferous  cavities  not 
greatly  enlarged.  Lateral  line  originating  at  a  distance  from  gill  opening,  usually  above 
it.  Pectorals  placed  medially,  below  upper  angle  of  gill-cleft.  Ventrals  stout,  with  outer 
ray  filamentous.  Dorsal  origin  behind  that  of  pectoral,  its  longest  spine  serrated  (though 
but  slightly  in  2f.  gigas).  A  considerable  space  between  the  two  dorsals.  Second  dorsal 
and  anal  not  very  unlike  in  height,  the  anal  being  somewhat  further  forward. 

Three  species  appear  to  belong  clearly  to  this  group;  N.  armatus  (Hector),  from  the 
South  and  Middle  Pacific,  400-2,425  fathoms  (Challenger  Eeport,  xxn,  150,  pi.  XL,hg.  A); 
N.  affinis  (Gunther),  from  the  east  coast  of  South  America,  1,900  fathoms;  and  N~.  gigax 
(Vaillant),  from  the  North  Atlantic,  2,082-2,128  fathoms. 

Nematonurus  is  a  thoroughly  characteristic  bathybial  genus.

simple,  conical,  about  20  to  25  on  each  side  of  either  jaw.  Eye  close  to  profile,  its  diameter 
one-fifth  the  length  of  the  head,  and  a  little  less  than  width  of  interorbital  space,  which  is 
one-fourth  of  head.  Length  of  barbel  equal  to  diameter  of  eye,  which  is  about  equal  to  the 
length  of  the  snout.  Scales  strongly  spinigerous,  with  spines  arranged  in  radiating  rows. 
Nme  above  and  thirty-four  rows  below  lateral  line,  which  contains  138  scales.  Head 
covered  with  rough  scales  like  those  on  the  body.     Limb  of  preoperculum  concave. 

First  dorsal  placed  comparatively  far  bade,  without  elevation  of  the  dorsal  outline  at 
its  base;  its  second  spine  almost  smooth,  but  with  a  lew  rugosities  near  its  tip;  its  height 
equal  to  about  half  that  of  the  body.  Distance  of  second  dorsal  from  first  equal  to  Hi  times 
the  length  of  the  base  of  the  latter  and  a  little  less  than  the  length  of  the  head.  Origin  of 
anal  nearly  under  middle  of  interspace  between  dorsals.  Its  height  similar  to  that  of 
second  dorsal.  Pectorals  rather  strong,  with  outer  ray  somewhat  produced.  Ventrals 
slightly  behind  root  of  pectoral,  far  in  front  of  origin  of  dorsal,  rather  strong,  with  outer 
ray  produced.

Macruriils,  having  the  dorsal  sub-continuous;  the  anal  much  higher  than  the  second 
dorsal.  Head  and  snout  long,  Qadus-Mke;  mouth  large,  lateral,  sub  terminal.  Scales  small, 
not  spinigerous,  but  with  about  five  feeble  radiating  keels.  Ventrals  in  advance  of  pecto 
rals.  Vent  Tar  forward,  almost  under  Last  rays  of  first  dorsal.  Pectorals  and  ventrals 
strong,  falciform,  the  outer  ray  of  each  prolonged,  that  of  the  ventral  exceedingly.  Dorsal 
spine  feebly  senate.     Barbel  minute. 

This  genus  is  proposed  for  the  reception  of  Macrurus  longifilis,  Giinther  (Ann.  and 
Mag.  Nat.  Hist.,  1S77.  xx,  439;  Challenger  Report,  xxn,  1887,  151,  pi.  XXXV),  a  species

The  type  is  28  inches  long,  and  is  admirably  figured  in  the  Challenger  Report. 

The  genus  is  named  in  honor  of  Professor  Henry  N.  Moseley,  F.  R.  8.,  of  Oxford 
University,  whose  contributions  to  natural  history  while  naturalist  of  H.  M.  S.  Challenger,

greater  thaii  the  vertical,  about  one-fourth  of  the  length  of  the  head,  and  equal  to  the 
width  of  the  interorbital  space  above  the  center  of  the  orbit.  Scales  very  rough,  each 
with  3  or  4  acute  and  prominent  spines;  4  series  between  the  first  dorsal  fin  and  the  lateral 
line;  the  crests  of  many  of  the  enlarged  dorsal  scales  are  coarsely  denticulated.  The 
entire  abdomen  covered  with  scales.  Distance  of  vent  from  the  isthmus  equal  to  that  of 
the  hind  margin  of  the  eye  from  the  extremity  of  the  snout.  Barbel  very  small.  Yentrals 
small,  inserted  in  front  of  the  pectoral  tin,  with  the  outer  ray  produced  into  a  short  filament. 
Anterior  branchial  arch  with  22  very  short,  styliforin  gill-rakers.     (Giinther.) 

This  form,  the  Pizzune  or  Pesci  sorici  of  the  Sicilian  fisherman,  the  Ealto  of  Cornigli- 
ano,  has  been  found  in  the  vicinity  of  Nice  and  Genoa,  as  well  as  about  Sicily,  but  not  as 
yet  in  the  Adriatic.  Vincigucria  states  that  in  the  Gulf  of  Genoa  it  is  more  abundant 
than  Ccelorhynchus.  With  the  long  line  at  GOO  fathoms,  off  Genoa,  he  obtained  10  speci- 
mens of  this  form  and  none  of  the  other.  Both  are  taken  at  sea,  some  miles  out  from 
Genoa,  by  the  tishermen  of  Cornigliano,  at  depths  of  300  fathoms  or  more.  The  French 
ships  took  01  specimens  oil' the  South  European  and  African  coast  in  400  to  1,400  fathoms. 

Canestrini  gives  a  fair  figure  and  Vinciguerra  a  better  one. 

TRACHYRHYNCHUS  MURRAYI,  Gintiiek. 

Trachyrhynehtts  Murrayi,  Gi  xtiier,  Challenger  Report,  xxn,  1887,  153,  pi.  xli,  Fig.  A. 

The  large  orbit  is  oval  in  shape,  nearly  one-fourth  of  the  length  of  the  head,  contained 
once  and  two-thirds  in  the  length  of  the  snout,  and  equal  to  the  width  of  the  interorbital 
space  above  the  middle  of  the  orbit.  Scales  almost  smooth,  having  1,  2,  or  3  small  spines 
developed  on  their  hind  margin ;  they  are  rather  irregularly  arranged,  in  4  series,  between  the 
dorsal  fin  and  the  lateral  line;  crests  of  the  dorsal  scales  simple,  triangular,  spines  directed 
backwards,  without  deuticulation.  The  abdomen  between  the  vent  and  the  roots  of  the 
ventral  fins  scaleless.  The  distance  of  the  vent  from  the  isthmus  nearly  equal  to  that  of 
the  hind  margin  of  the  eye  from  the  extremity  of  the  snout.  Barbel  minute.  Ventral  fin 
very  small,  scarcely  in  front  of  the  pectoral,  with  the  outer  ray  produced  into  a  filament, 
which  does  not  reach  the  vent.  Pectoral  as  long  as  the  postorbital  portion  of  the  head. 
Anterior  branchial  arch  with  22  very  short  styliforin  gill-rakers. 

Light  yellowish  (in  spirits):  vertical  lius,  ventral  filament,  interior  of  the  mouth  and 
branchial  cavity  black.     D.  9;  P.  23;  Y.  7.     (Giinther.) 

This  species  was  discovered  by  the  Knight  Errant  in  the  Faroe  channel,  station  4,  at  a 
depth  of  555  fathoms. 

MACRURONUS,  Giinther. 

Macruronua,  GUnther,  Zool.  Record,  VIII,  1873.  103;  Challenger  Report,  xxn,  1887,  157. 

1 1  ead  and  body  compressed,  covered  with  cycloid  scales;  trunk  not  abbreviated.  Bones 
of  the  head  rather  firm,  with  narrow  cavities.  Bye  large;  snout  rather  pointed ;  mouth  wide, 
lateral.  Teeth  in  the  upper  jaw  biserial,  those  of  the  outer  series  and  those  of  the  single 
mandibulary  series  strong.  Gill  membrane  slightly  united  in  front;  7  branchiostegals;  4 
gills  with  the  gill-laminae  well  developed;  the  first  branchial  arch  free,  with  long  lanceolate 
gill  rakers.    Bays  of  the  second  dorsal  well  developed  throughout  its  length.    Barbel  none. 

This  genus  includes  a  single  species,  Macruronus  Nov(e-zelandi<e,  (Hector),  Giinther. 
(Figure  350.)  (Hector,  Trans.  New  Zealand  Inst.,  in,  130,  pi.  xvm,  fig.  1. — Hutton,  Fish. 
New  Zealand,  49. — Giinther,  Challenger  Beport,  xxn,  18S7,  157.) 

Of  this  fish  Dr.  Giinther  examined  specimens  from  New  Zealand,  Tasmania,  and  the 
Messier  Channel,  the  largest  being  nearly  2  feet  long.  "All  of  them,"  he  writes,  "seem  to 
have  been  caught  near  the  surface  and  at  no  great  distance  from  the  shore,  and  it  is  not 
probable  that  it  descends  to  the  same  great  depth  as  the  other  Macruri.  Like  Lepidopus, 
it  seems  to  live  for  the  greater  part  of  the  year  at  a  small  depth,  and  to  periodically 
approach  the  shore  at  certain  seasons.  Hutton  says  that  it  is  thrown  up  in  large  quanti- 
ties on  the  shores  of  Cook  Straits  after  heavy  gales."

STEINDACHNERIA,  <; >i:  &   lii:.\x,  n.  g. 

Steindachneria,  Goose  &  Beak,  in  Agassiz,  Three  Cruises  of  the  Blake,  n,  j>.  26,  1888. 

A  genus  of  Macruridce,  with  large  terminal  mouth,  compressed  body,  and  tapering  tail;  a 
short  spinous  dorsal  and  a  long,  soft  dorsal  fin,  the  two  contiguous.  Both  dorsals  elevated 
anteriorly;  anal  tin  consisting  of  a  differentiated  elevated  anterior  portion  and  a  very  long 
low  portion.  Vent  in  the  anterior  third  of  the  length.  The  intermaxillary  and  mandibular 
teeth  biserial,  the  outer  scries  much  enlarged.  Vomerine  teeth  present.  Head  of  moderate 
size,  its  hones  soft  and  cavernous.  Eye  large.  Gill  openings  wide,  the  membranes  con- 
nected anteriorly,  but  not  attached  to  the  isthmus;  gill  rakers  slender,  moderately  numer- 
ous. No  pseudobranchise.  Branchiostegals,  7.  Pectorals  and  ventrals  both  immediately 
under  the  spinous  dorsal.     Scales  thin,  cycloid,  and  deciduous. 

Similar  in  appearance  to  Macruronus  novcezelandice,  from  which  it  differs  in  several  impor- 
tant particulars:  (1)  The  tail  is  much  more  tapering  in  Steindachneria;  (2)  the  vent  is  in 
advance  of  the  end  of  the  anterior  third  of  the  body;  (3)  the  anal  fin  has  a  distinct  elevated 
portion;  (4)  vomerine  teeth  arc  present;  (5)  the  bones  of  the  head  are  soft  and  cavernous. 
This  remarkable  gen  us  is  named  in  honor  of  Dr.  Frauz  Steindachner,  Custos  of  the 
Imperial  Zoological  Museum  of  Vienna. 

STEINDACHNERIA  ARGENTEA,  Goode  aud  Beax,  u.  b.     (Figure  351.) 

The  head  and  body  are  compressed  and  the  tail  tapers  to  a  very  fine  point.  Greatest 
height  of  the  body  at  the  origin  of  the  ventral  (.30  millimeters  in  the  type  specimen)  is 
contained  7i  times  in  the  total  length.  The  height  at  the  anal  origin  (28  millimeters)  is 
contained  about  S  times  in  the  total  length. 

Scales  are  small,  deciduous,  cycloid,  0  rows  between  the  lateral  line  and  the  origin  of  the 
soft  dorsal.  The  origin  of  the  anal  is  about  under  the  seventeenth  row  of  scales.  The 
length  of  the  head  (42  millimeters)  is  contained  5£  times  in  the  total  length.  The  inter- 
orbital  area  equals  the  length  of  the  snout  and  nearly  one-fifth  the  length  of  the  head. 
The  postorbital  part  of  the  head  (22  millimeters)  is  nearly  twice  as  long  as  the  eye,  which 
is  (12  millimeters)  slightly  more  than  one  fourth  the  length  of  the  head.  The  snout  is  ob- 
tuse, its  length  about  three-fourths  that  of  the  eye.  The  nostrils  are  placed  nearer  to  the 
eye  than  to  the  end  of  the  snout;  the  anterior  nostril  is  nearly  circular,  the  posterior  much 
longer  aud  slightly  concave.  No  barbel.  The  maxilla  is  dilated  at  the  extremity  and  is 
somewhat  produced  downward  into  an  obtuse  poiut.  It  extends  nearly  to  the  vertical 
through  the  posterior  margin  of  the  orbit,  and  can  be  concealed  under  the  preorbital.  Its 
length  (20  millimeters)  is  nearly  one-half  that  of  the  head.  The  intermaxilla  is  slightly 
protractile,  much  attenuated  posteriorly,  its  length  about  equal  to  that  of  the  maxilla. 
The  mandible  extends  slightly  behind  the  posterior  margin  of  the  eye,  its  length  (24  milli- 
meters) equaling  twice  the  length  of  the  eye.  Intermaxillary  and  mandibular  teeth 
biserial,  the  outer  series  enlarged  and  rather  widely  set.  Some  of  the  enlarged  teeth  are 
slightly  sagittate  at  the  tip.  Vomerine  teeth  well  developed.  Upper  pharyngeals  in  two 
broad,  well-developed  patches.  Gill-rakers  slender,  about  19  on  the  first  arch,  4  or  5  of 
which  are  above  the  angle.     The  longest  gill-raker  is  nearly  one-half  as  long  as  the  eye. 

The  distance  of  the  first  dorsal  from  the  snout  (44  millimeters)  is  nearly  one-fifth  of 
the  total  length.  The  first  spine  is  elongate,  filiform,  and  when  laid  backward  reaches  the 
fourteenth  ray  of  the  second  dorsal.  The  base  of  the  fin  about  equals  the  length  of  the 
eye.  The  longest  ray  of  the  second  dorsal  (the  second)  is  about  two  tilths  the  length  of  the 
head.  The  rays  diminish  in  size  very  rapidly,  becoming  minute  at  the  extremity  of  the 
tail.  The  anal  originates  under  the  sixth  ray  of  the  second  dorsal,  not  far  behind  the 
vent.  The  anterior  elevated  portion  consists  of  10  rays,  all  of  which  except  the  first  are 
divided.  The  second  ray  is  the  longest,  its  length  (24  millimeters)  being  twice  the  length 
of  the  eye.  The  last  ray  is  only  about  one-seventh  as  long  as  the  second.  It  is  separated  by 
a  small  membrane  from  the  remaining  portion  of  the  tin,  which  consists  of  very  minute 
rays,  the  longest  of  them  scarcely  more  than  2  millimeters  in   length.     The   vent   is   under

the  fourth  ray  of  the  second  dorsal.  The  ventral  is  placed  under  the  base  of  the  pec- 
toral and  about  under  the  third  spine  of  the  hist  dorsal.  Its  first  ray  is  filamentous,  reach- 
ing, a? ben  extended,  to  the  anal  origin.  The  pectoral  when  extended  reaches  to  below  the 
fifteenth  ray  of  the  second  dorsal,  its  length  (42  millimeters)  equalling  the  length  of  the 
head. 

Radial  formula:  D.  Vin,  123+ ;  A.  10+113;  P.  15;  V.  S.  Color,  silvery;  upper  parts

The  type  specimen,  Cat.  No.  37350,  U.  S.  N.  M.,  233  millimeters  in  length,  was  obtained 
by  the  Albatross  from  station  2378,  off  the  delta  of  the  Mississippi  River,  in  30°  14'  30"  If.

BATHYGADUS.   Gunther. 

Bathygadus,  Gcntiier,  Ann.  and  Mag.  Nat.  Hist.,  II,  1878,  23;  Challenger  Report,  xxn,  1887,  154. 

Radial  formula:  A  genus  of  Macruridce  with  large  terminal  mouth,  prominent  nape,  no 
teeth,  lanceolate  gill  rakers;  free,  notched  branchiostegal  membrane;  high  vertical  tins; 
first  dorsal  composed  largely  of  branched  rays;  anal  fin  set  far  back. 

Head  large,  fleshy,  without  prominent  ridges,  spiny  armature  or  external  depressions; 
nape  elevated,  hump-like.  Snout  broad,  obtuse,  not  produced.  Mouth  terminal,  very 
large;  suborbital  ridge  very  low,  not  joined  to  the  angle  of  the  preoperculuin.  The  max- 
illary may  be  entirely  received  within  a  groove  under  the  prefrontal  and  suborbital  bones; 
its  tip  narrowed  and  blade-like;  intermaxillaries  protractile  downwards,  separated  ante 
riorly,  rib  shaped,  compressed  vertically,  very  broad  and  without  true  teeth;  provided  pos- 
teriorly with  a  short  flange,  which  is  received  underneath  the  maxillary.  Mandible  received 
within  the  intermaxillary  bones,  without  true  teeth,  but  with  minute  asperities,  similar  to 
those  in  the  intermaxillaries.     Vomer  and  palatines  toothless. 

Barbel  sometimes  present.  No  pseudobranchise.  Gill-rakers  numerous,  moderate, 
lanceolate,  with  minute  denticulations  along  their  inner  edge.  Branchiostegal  membrane 
free  from  the  isthmus,  deeply  cleft.  Branchiostegals  7,  very  stiff.  Gill-opening  very  wide. 
Operculum  with  a  blunt,  spine-like  prominence  at  its  angle.  Yentrals  below  the  pectorals, 
many-rayed,  the  anterior  rays  produced.  Dorsal  consisting  for  the  most  part  of  branched 
rays.  Scales  cycloid,  plain;  lateral  line  strongly  arched  over  the  pectoral. 
Bathygadus  cottoides,  Gunther,  (Challenger  Report,  xxn,  154,  pi.  xlii,  fig.  A)  was  taken 

by  the  Challenger  between  the  Kermadecs  and  New  Zealand  in  520  to  700  fathoms. 
Bathygadus  multifilis,  Gunther,  (loc.  cit.,  155,  pi.  xlii,  fig.  B)  a  form  near  to  B.  longlfilis, 

is  known  only  from  south  of  the  Philippine  Islands  in  500  fathoms. 

BATHYGADUS  FAVOSUS,  Goode  and  Bean.     (Figure  352.) 

Bathygadus  favosus,  Goode  and  Bean,  Bull.  Mus.  Conip.  Zool.,  xii,  No.  5,160. 

The  body  is  heavy,  stout;  its  greatest  height,  at  origin  of  first  dorsal  (57  millimeters  in 
type  specimen),  is  contained  a  little  more  than  6  times  in  the  total  length.  The  profile  of 
the  body  descends  gradually  and  in  a  slight  curve  from  the  first  dorsal  to  the  snout. 

The  scales  are  small,  deciduous,  cycloid,  without  armature,  about  135  in  the  lateral 
line,  about  10  above  and  10  below  the  lateral  liue,  the  latter  series  counted  from  the  vent. 

The  length  of  the  head  (G5  millimeters)  is  contained  about  54  times  in  total  length. 
The  interorbital  area  is  slightly  convex;  its  greatest  width  (22  millimeters)  equals  about 
one-third  of  the  length  -of  the  head.  The  postorbital  part  of  the  head  is  2§  times  as  long  as 
the  eye,  which  is  nearly  round,  its  diameter  equal  to  one-fifth  the  length  of  the  head.  The 
snout  is  broad,  oblique,  its  width  at  the  nostrils  (23  millimeters)  a  little  more  than  the 
width  of  interorbital  area;  its  length  (17  millimeters)  slightly  more  than  one-quarter  that 
of  the  head.  The  nostrils  are  close  to  and  in  front  of  the  middle  of  the  eye,  the  posterior 
one  somewhat  the  larger.    No  barbel. 

The  teeth  in  both  jaws  in  villiform  bands ;  a  naked  space  at  the  symphysis  of  the  inter- 
maxillaries. The  intermaxillary  bands  are  more  than  twice  as  wide  as  those  on  the  inau- 
dible.   Vomer  and  palatine  toothless.    The  longest  gill-raker  on  the  anterior  arch  is  slightly

more  than  half  as  long  a>  the  eye.  The  number  of  gill-rakers  on  tlii.s  arch  is  25,  20  being 
below  the  angle. 

Pseudobranchise  present,  very  rudimentary  in  some  individuals,  in  others  wanting  or 
present  only  upon  one  side. 

The  first  dorsal  is  distant  from  snout  68  millimeters,  which  is  slightly  more  than 
length  of  the  head;  the  length  of  its  base  (24  millimeters)  is  abont  equal  to  width  of  the 
snout  at  the  nostrils.  The  tin  consists  of  -  spines,  the  first  of  which  is  minute,  and  9 
branched  rays.  The  length  of  the  longest  spine,  which  is  armed,  is  contained  twice  in  that 
of  the  head  (specimens  examined  impel  feet).  The  second  dorsal  begins  immediately  behind 
the  first, the  membrane  being-  continuous.  The  anterior  rays  are  longest  (apparently  about 
one-fourth  the  length  of  the  head). 

The  anal  is  lower  than  the  second  dorsal;  its  distance  from  the  snout  (112  millimeters) 
is  about  equal  to  one-third  of  the  total  length. 

The  pectoral  is  inserted  under  the  anterior  rays  of  the  first  dorsal  and  very  slightly  in 
advance  of  the  origin  of  the  ventral.     Its  length  is  more  than  half  that  of  the  head. 

The  distance  of  the  ventral  from  the  snout  (69  millimeters)  is  contained  5  times  in  the 
total.  This  fin  is  inserted  nearly  under  the  base  of  the  pectoral;  the  first  ray  is  somewhat 
produced;  its  tip  reaches  to  the  fourth  ray  of  the  anal  fin. 

Radial  formula:  D.  n,  9, 125;  A.  110;  V.  9;  P.  14;  B.  7. 

Color,  bluish-brown,  darkest  upon  head  and  abdomen,  especially  in  Museum  specimens. 

The  type  specimen,  350  millimeters  in  length,  was  obtained  by  the  Blake  from  station 
lxxx,  off  Martinique,  at  a  depth  of  472  fathoms. 

Collateral  types  were  secured  by  the  Albatross  from  station  2302,  in  28°  47'  30"  N.  lat.,

BATHYGADITS  ARCUATUS,  Goode  and  Beau. 

Bathygadus  arcuatus,  Goode  and  Bean,  Bull.  Mns.  Com]).  Zool.,  xn,  No.  5,  158. 

The  body  is  shaped  much  as  in  Chalinura  Simula,  but  the  nape  is  still  more  convex.  Its 
greatest  height  (57  millimeters  in  the  type  specimen )-is  5'^  in  its  total  length.  The  back  is 
gibbous,  the  dorsal  outline  rising  rapidly  from  the  interorbital  region  to  the  origin  of  the 
first  dorsal,  whence  it  descends  gradually  to  the  end  of  the  tail. 

The  scales  are  moderate,  cycloid,  subovate,  without  armature;  those  of  the  abdominal 
region  and  those  above  the  pectorals  the  largest.  The  lateral  line  is  strongly  arched  over 
the  pectorals;  the  length  of  the  arched  portion  contained  about  3^  times  in  the  straight 
portion;  the  greatest  height  of  the  arch  is  about  one-fourth  of  the  length  of  its  chord. 
The  number  of  scales  in  the  lateral  line  is  about  140,  eight  rows  of  scales  between  the 
origin  of  the  dorsal  and  the  arch  of  the  lateral  line,  13  or  14  rows  of  scales  between  the 
vent  and  the  lateral  line  counting  backwards,  22  counting  forwards.  Scales  cover  all  parts 
of  the  head  except  the  jaws  and  chin. 

The  length  of  the  head  is  contained  5  times  in  total.  Interorbital  area  flat,  its  width 
(11  millimeters)  equal  to  one-sixth  length  of  head.  Postorbital  portion  of  head  about  24 
times  diameter  of  eye.  The  operculum  terminates  in  a  Hat  obtuse  spine,  its  length,  includ 
ing  the  Hap,  about  equal  to  diameter  of  eye.  I'l  eopei  culum  entire,  witli  a  prominent  ridge 
in  advance  of  its  posterior  edge.  The  orbit  is  rounded,  the  least  diameter  of  the  eye  equal

margin  of  the  orbit,  and  is  not  connected  with  the  angle  of  the  preoperculum. 

Nostrils  immediately  in  front  of  the  lower  part  of  the  eye,  not  tubular,  the  anterior  one 
very  small,  pore-like,  only  about  one-fourth  as  large  as  the  posterior  one.  Distance  of 
anterior  nostril  from  tip  of  snout  about  three-fourths  length  of  eye.  Length  of  barbel  (51 
millimeters)  Of  in  length  of  body,  and  equal  to  length  of  head  without  snout  (in  the  larger 
specimen  the  barbel  is  as  long  as  the  mandible),  more  than  3  times  as  long  as  the  eye. 

There  are  no  true  teeth,  the  iutertnaxillaries  and  mandible  being  broad  plates,  covered 
with  minute  asperities.    A  naked  space  at  the  symphysis  of  the  intermaxillaries. 

Distance  of  first  dorsal  from  snout  (77  millimeters)  nearly  3J  times  length  of  its  base;  the 
fin  contains  2  spinous  and  10  or  11  branched  rays;  the  first  spine  is  minute,  the  second  (in 
the  types)  somewhat  mutilated,  its  length  nearly  3  in  length  of  head.1  It  is  not  stouter 
than  the  branched  rays,  and  is  entirely  smooth. 

The  second  dorsal  is  separated  from  the  first  by  a  very  short  interspace,  equal  to  about 
one  third  of  the  length  of  the  eye.  Its  rays  are  long,  subequal,  the  first  slightly  the 
longest,  its  length  equal  to  that  of  the  base  of  tlio  first  dorsal. 

The  anal  is  much  lower  than  the  dorsal,  the  longest  rays  being  in  front,  its  third  ray 
about  half  as  long  as  the  first  ray  of  the  second  dorsal;  this  fin  is  inserted  under  the 
seventh  ray  of  the  second  dorsal.  About  three  of  the  terminal  rays  might  be  considered 
caudal  rays. 

Pectoral  inserted  slightly  in  advance  of  the  ventral,  which  is  in  about  the  same  vertical 
with  the  origin  of  the  first  dorsal.  The  second  ray  of  the  pectoral  is  slightly  produced. 
The  length  of  the  fin  equal  to  that  of  the  head  without  the  snout. 

Ventral  insertion  distant  from  the  tip  of  the  snout  a  distance  equal  to  that  of  first 
dorsal  from  snout.  The  first  and  second  rays  are  filamentous,  the  latter  slightly  the  longer, 
and  extending  to  the  fifteenth  (or  eighteenth  in  larger  specimen)  ray  of  the  anal  fin. 

Radial  formula:  D.  II,  9-10  (135);  A.  (120);  P.  25;  V.  8.

continuous  with  the  first,  its  anterior  rays  longest  and  not  diminishing  rapidly  in  size 
toward  the  tail. 

The  anal  is  inserted  under  the  ninth  ray  of  the  second  dorsal,  its  rays  much  shorter  than 
those  in  the  dorsal,  and  situated  about  the  same  distance  apart. 

The  pectorals  are  inserted  under  the  anterior  portion  of  the  first  dorsal,  the  first  ray

Color,  yellowish-gray,  abdomen  bluish. 

This  form  is  closely  allied  to  ]>.  mnltifiJis,  described  by  Giinther  from  off  the  Philippines 
(Challenger  Report,  xxn,  1887,  155,  pi.  xlii,  tig.  B).  which,  however,  appears  to  have  a 
smaller  eye,  less  elongate  filaments,  and  ventral  inserted  in  advance  of  the  first  dorsal, 
while  the  anal  appears  to  be  further  back,  under  the  twelfth  or  thirteenth  ray  of  the 
second  dorsal.  Both  species  are  provided  with  long,  slender  barbels.  In  other  respects 
they  are  closer  to  B.  cottoides,  the  typical  species,  than  to  B.  macrops. 

The  type  specimens  (Cat.  No.  37338,U.  S.  N.  M.),  225  and  233  millimeters  in  length,  were 
taken  by  the  Albatross  at  station  2392,  in  28°  47'  30"  N.  lat.,  87°  27'  W.  Ion.,  at  a  depth  of

BATHYGADUS  DISPAR,  (Vaillant),  Goode  and  Bean. 

Hymenocephalui  dispar,  Vaillant,  Exp.  Scient.  Travailleur  ot  Talisman,  221,  pi.  xxiv,  fi£.  1. 

This  form,  obtained  by  the  French  explorers  off  the  coastof  Morocco  ata  depth  of  1,105 
fathoms,  closely  resembles  the  two  preceding,  but  according  to  Vaillant  its  body  is  thicker, 
its  interorbital  space  comparatively  narrower,  the  ventral  filament  shorter,  and  the  barbel 
stronger  and  longer.  Since  only  one  .specimen  was  studied  there  is  scarcely  sufficient  evi- 
dence that  this  is  a  well-marked  species. 

Vaillant's  characters  upon  which  Bathygadus ia  separated  from  theheterogeneous  assem- 
blage formed  by  him  in  his  supposed  genus  Hymenocephdlus  are  entirely  superficial.  The 
presence  of  a  barbel  led  him  to  separate  this  form  from  its  near  ally  Bathygadus  melano- 
bronchus.

first,  its  anterior  rays  the  longest,  about  1  times  in  length  of  head. 

The  anal  is  inserted  under  the  fourteenth  ray  of  second  dorsal.  Its  rays  are  all  very 
short.    In  a  distance  equal  to  length  of  head,  counting  back  from  insertion,  there  are  33  rays. 

The  pectoral  is  inserted  under  the  first  branched  ray  of  the  first  dorsal;  its  length  in 
the  most  nearly  perfect  specimens  equals  the  length  of  the  head  without  the  snout.

Lycnnid/r,  OfNTUER,  Chullongor  Report,  xxil,  1887,  158. 

Body  terminating  in  a  long  compressed  tapering  tail,  covered  with  small  scales.  A 
continuous  dorsal  fin  occupies  the  back  to  the  extremity  of  the  tail,  but  a  division  into  two 
portions  may  be  considered  to  be  indicated  by  the  prolongation  of  some  of  the  anterior  dor-

LYCONUS  PINNATUS,  Gunther. 

Lyconue  pinnatus,  GOnther,  Challenger  Report,  xxn,  1887,  158,  pi.  42,  fig.  C. 

Head  compressed,  as  deep  as  it  is  long,  without  snout.  The  interorbital  space  is  rather 
flat,  narrower  than  the  round  eye,  which  lies  immediately  below  the  upper  profile;  its 
.diameter  is  one-third  of  the  length  of  the  head  and  rather  longer  than  the  snout.  The 
mouth  ascends  obliquely  forward,  and  extends  behind  the  middle  of  the  orbit;  the  jaws 
are  even  in  front.  The  teeth  are  but  few  in  number,  and  besides  the  two  long  lateral  fangs 
there  are  only  three  shorter  ones  developed  in  the  lower  jaw.  Opercular  bones  very  thin, 
and  the  infraorbitals  narrow,  separating  the  maxilla  from  the  eye  by  a  narrow  space  only. 

The  distance  of  the  vent  from  the  root  of  the  ventrals  is  rather  more  than  the  length 
of  the  head.     The  tail  tapers  into  an  exceedingly  fine  filament. 

flic  dorsal  tin  commences  above  the  base  of  the  pectoral,  and  is  composed  of  very 
delicate  simple  rays;  there  is  no  break  in  its  continuity,  but  some  of  its  anterior  rays. 
perhaps  3  or  4,  are  much  prolonged,  but  as  this  portion  is  injured,  no  more  precise  informa- 
tion can  be  given.  The  anal  fin  commences  immediately  behind  the  vent,  and  its  rays  are 
considerably  shorter  than  those  of  the  dorsal.  The  pectoral  has  a  narrow  base,  and  is 
directed  obliquely  upward;  it  consists  of  thirteen  rays,  aud  is  exceedingly  elongate,  the 
middle  rays  extending  far  beyond  the  vent. 

The  ventral  fins  are  mutilated;  they  are  composed  of  10  rays  and  situated  below  the 
base  of  the  pectoral. 

Scales  very  small,  thin,  and  deciduous.

A  group  of  pleuronectoid  fishes  closely  related  to,  if  not  a  subdivision  of,  the  genus 
Ptcuronectes;  having  ctenoid  scales,  a  lateral  line  strongly  arched  in  front,  and  without  an 
accessory  branch. 

The  type,  Plctitonntin  limn  tula,  Linnams  (=I4manda  vulgaris,  Gottsche)  is  found  along 
the  coasts  of  Europe  from  Iceland  to  the  Gulf  of  Gascony.  The  British  fishermen  take  it 
on  their  deep  sea  lines,  and  it  no  doubt  descends  below  the  hundred  fathom  line,  especially 
in  Bummer. 

Limanda  microstoma,  (Giinther),  is  from  the  Admiralty  Islands,  at  a  depth  of  152 
fathoms.

Myzopseita  rostrala,  Gill,  loe.  cit. 

Body  strongly  compressed,  its  height  2^  times  in  its  length.  Length  of  head  one- 
fourth  that  of  body;  snout  projecting,  forming  a  strong  angle  above  upper  eye  with  the 
descending  profile.  Teeth  conical,  closely  set,  in  a  single  series,  on  jaws.  Gill-rakers  mod 
erate,  weak,  not  toothed.  Diameter  of  eye  two-thirds  of  length  of  head;  the  lower  eye 
slightly  in  advance  of  upper;  separated  from  it  by  a  high,  narrow  ridge,  scaled  posteriorly 
and  continuing  backward  to  beginning  of  lateral  line.  Scales  imbricated:  those  on  right 
ctenoid,  on  left,  nearly  smooth.  Lateral  line  simple,  with  low  arch,  whose  depth  is  less 
than  two-fifths  its  length,  containing  about  loo  scales. 

Caudal  peduncle  short,  higher  than  long.  Dorsal  origin  over  middle  of  eye,  its  middle 
rays  longest;  pectoral  less  than  two-fifths  as  long  as  head;  caudal  fin  rounded;  a  strong 
anal  spine.  Concealed  spine  behind  ventrals;  ventrals  of  colored  side  partly  lateral,  that 
of  white  side  wholly  so. 

Radial  formula :     D.  80-85;  A.  58-62. 

Color,  body  and  fins  of  right  side  brownish  olive,  with  irregular,  rusty  spots;  caudal 
fin,  caudal  peduncle,  and  margins  of  dorsal  and  anal  fins  lemon  yellow  on  the  left  side. 

Specimens  from  the  far  North,  as  described  by  Storer  (P.  rostrata),  are  rounder  in  out- 
line, have  fewer  rays  in  the  vertical  fins  and  a  blunter,  more  prominent  snout,  and  may 
perhaps  sometime  be  recognized  as  belonging  to  a  distinct  subspecies. 

This  species  is  found  inshore  on  the  New  England  coast  in  winter,  but  in  summer 
retreats  to  deep,  cold  water.  Numerous  specimens  were  taken  by  the  Fish  Hairk  in  1874, 
1S7">,  and  1880,  south  of  Cape  Cod,  in  deep  water.  The  most  southern  locality  at  that  time 
found  was  the  Pecten  ground  off  Watch  Hill,  Rhode,  Island.  Examples  were  obtained 
from  station  984,  in  11=31' N.  lat.,  60°  28'  W.  Ion.,  at  a  depth  of  33  fathoms;  Cat.  No.  28821, 
U.  S.  N.  M.,  from  station  948,  off  Penikese  Island,  Buzzard's  Bay,  in  7  fathoms;  and  Cat. 
No.  28818,  LT.  S.  N.  M.,  from  station  927,  in  Vineyard  Sound,  at  a  depth  of  11  fathoms.  The 
Albatross  secured  specimens  from  station  2440,  in  43°  38'  N.  lat.,  49°  49'  30"  W.  Ion.,  at  a 
depth  of  33  fathoms;  Cat.  No.  33425,  U.  S.  N.  ML,  from  station  2082,  in  41°  09'  50"  N.  lat., 
00°  31'  50"  W.  Ion.,  at  a  depth  of  49  fathoms;  and  Cat.  No.  33416,  U.  S.  N.  M.,  from  station 
2058,  in  4L°  57'  30"  N.  lat.,  67°  58'  VV.  Ion.,  at  a  depth  of  35  fathoms;  and  the  Speedwell, 
from  station  57,  in  Halifax  Harbor,  at  a  depth  of  16  fathoms;  from  station  75  in  Halifax 
Harbor,  and  Cat.  No.  24026,  IT.  S.  N.  M.,  from  station  196,  off  Thatcher's  Island,  in  20 
fathoms.  A  single  individual  (Cat.  No.  23767,  U.  S.  N.  M.)  was  also  taken  at  Proviucetown, 
Mass.,  on  July  29,  1879.

136.— GCinther,  Challenger  Report,  xxn,  166. 

Body  elliptical,  with  angular  outlines.  Its  height  is  three-eighths  of  its  length,  and 
slightly  more  thau  twice  length  of  head.  Its  height  at  the  ventrals  (25)  is  one  fourth  of  its 
length  and  less  than  distance  from  snout  to  origin  of  anal.  Its  least  height,  at  base  of 
tail  (12),  is  half  its  height  at  ventrals.  The  body  is  thin,  its  greatest  width  (7)  not  exceed- 
ing the  diameter  of  the  orbit. 

Scales  subcircular,  small,  strongly  pectinate  on  the  colored  side,  cycloid  on  the  blind 
side,  where  they  are  also  larger,  there  being  about  fifty  in  the  lateral  line  (behind  the  curve), 
while  on  the  colored  side  there  are  probably  sixty.  The  lateral  line  on  the  colored  side 
makes  a  very  abrupt,  conspicuous,  angular,  high  curve  over  the  pectoral  fin.  The  chord 
of  this  arc  is  nearly  as  long  as  the  head  of  the  fish,  its  height  half  as  great.  The  scales 
in  the  lateral  line  are  highly  specialized,  particularly  along  the  curve,  which  appears  to 
contain  about  twenty-seven  of  them,  while  posterior  to  this,  in  the  straight  portion,  there

are  about  sixty.  The  specialized  scales  of  the  lateral  line  extend  far  oul  upon  t ho  caudal 
tin.  On  the  blind  side  the  lateral  line  is  little  conspicuous,  the  scales  \  ery  slightly  special 
i/.ed,  and  it  becomes  obsolete  in  the  region  VI  here,  upon  t  he  colored  side,  t  he  curve  is  located. 
The  scales  extend  tar  out  upon  the  caudal  fin,  but  are  not  present  upon  the  other  tins. 

Bead  very  short,  its  length  (IS)  contained  about  five  limes  and  one-half  in  the  total. 
The  snout  is  very  short  (2),  one-fiftieth  of  the  total,  and  the  mouth  is  small,  its  clefl  sub 
vertical,  and  the  maxillary  extending  very  slightly  behind  the  anterior  margin  of  the  orbit. 
The  teeth  are  inconspicuous,  apparently  iu  two  rows,  stronger  and  mure  numerous  on  the 
blind  side,  barely  discernable  in  upper  jaw,  absent  elsewhere  in  the  mouth. 

Eyes  large,  prominent;  their  diameters  (7)  greater  than  the  length  of  the  maxillary  (6) 
and  equal  to  that  of  the  mandible  (6).  They  are  very  closely  set,  the  interorbital  space 
marked  by  a  knife-like  edge  of  bone.  The  upper  eye,  in  its  outline  trenching  upon  the 
dorsal  outline  of  the  head,  is  almost  directly  above  its  mate.  Together  they  occupy  nearly 
three-fourths  of  the  width  of  the  head  at  the  perpendicular  passing  through  their  centers. 

The  dorsal  tin  begins  over  the  posterior  part  of  the  pupil  of  the  upper  eye.  Its  rays 
are  long,  widely  separated,  and  with  their  tips  protruding  beyond  the  membrane,  giving  to 
this,  as  also  to  the  anal,  a  ragged,  irregular  appearance.  Its  greatest  height  (8)  is  equal  to 
half  the  length  of  the  head.  The  anal  is  inserted  under  the  axil  of  the  pectoral,  and  its 
height  is  about  the  same  as  that  of  the  dorsal. 

The  length  of  the  caudal  (20)  is  equal  to  one -fifth  of  that  of  the  body,  without  including 
caudal.  It  is  broad,  fan-shaped,  acutely  convex  in  outline.  The  distance  of  the  ventral 
from  the  snout  (28)  is  about  one  third  the  length  of  the  base  of  the  dorsal.  The  arrange- 
ment of  these  fins  upon  the  ventral  keel  is  much  as  in  Limanda  ferruginea,  the  right  tin 
being  almost  upon  the  median  line.    The  pectorals  are  normal. 

The  color  is  grayish  brown,  mottled  with  darker  patches.  There  is  a  conspicuous  black 
blotch  upon  the  outer  rays  of  the  caudal  on  either  side. 

Radial  formula:  D.  63-6S;  A.  54-56;  0.18;  P.7;  V.6;  lateral  line  aboutSS;  27  in  curve. 

The  extreme  brevity  of  the  snout  and  the  elongate-elliptical  form  of  the  body  render  its 
shape  very  uulike  that  of  Limanda  ferruginea  of  our  own  coast  and  Limanda  platessoides  of 
t  he  Eastern  Atlantic  Iu  its  general  appearance,  however,  except  that  the  ventrals  are  not 
both  lateral,  it  resembles  considerably  the  species  mentioned  above.

A  Glyptocephalus,  having  the  height  of  body  3  times  (more or  less)  in  its  own  length;  the 
length  of  the  head  about  5J  times.  Scales  small;  head  scaly,  except  on  snout  aud  ridge 
between  the  eyes.  Lateral  line  straight.  Snout  shorter  than  diameter  of  orbit,  which  is 
one-fourth  of  length  of  head.  Jaws  subequal  in  front,  the  maxillary  shorter  than  the  eye. 
Upper  jaw  with  truncated  incisor-like  teeth  on  the  blind  side,  in  a  close-set  series  of  about 
20.  Eyes  separated  by  a  sharp  ridge,  the  lower  somewhat  in  advance.  Origin  of  dorsal 
tin  about  middle  of  eye,  its  distance  from  caudal  somewhat  less  than  half  depth  of  caudal 
peduncle.  Middle  dorsal  rays  longest,  more  than  half  as  long  as  head;  pectoral  half  as 
long  as  head. 

Eadial  formula:  D.  102—120;  A.  87—102;  L.  hit,  125;  Vert.  58. 

Color,  grayish-brown ;  membranes  of  the  fins  with  dark  spots ;  pectoral  of  the  colored 
side  dark. 

The  pole-flounder  is  a  well-known  cold-water  fish  of  Europe.     It  was  obtained  by  Strom 


DISCUSSION    OP    SPECIES    AND    THEIB    DISTRIBUTION  431 

in  the  Trondhjetn  Fiord  at 200 fathoms,  and  by  tin-  Norwegian  Expedition  at  125-250  fathoms 
off  Kiinnark  and  the  Lofoten  Islands. 

[t  occurs  also  in  the  North  Sea  and  around  the  British  Island-,  and  France  where, 
however,  ii  is  rare,  especially  on  the  west  coast,  though  it  has  been  found  as  far  south  as 
Arcaehon. 

On  our  own  coast,  though  never  found,  near  the  shore,  it  is  one  of  the  si    abundant 

of  the  deep-water  pleuronectoids. 

The  following  statistics  are  the  result  of  a  careful  study  of  numerous  specimens 
trawled  in  the  deep  water  off  Salem,  Mass.,  ou  La  Have  Bank,  and  on  the  coast  of  Nova 
Scotia,  off  Halifax,  in  Halifax  Harbor,  and  in  Bedford  Basin,  Halifax.  They  are  the 
result  of  detailed  measurements  of  22  individuals,  including  authentically  named  European 
specimens  from  the  University  of  ('hristiania,  and  the  Bonaparte  Collection,  the  type  of 
(I.  aeadianus,  .">  specimens  from  Massachusetts  Bay,  5  from  La  Have  Bank,  and  11  from  the 
vicinity  of  Halifax. 

(1)  Height  of  body. — This  is  stated  to  be  about  --,  of  length  exclusive  of  caudal,  and  3$ 
iu  total  length.  In  the  series  studied,  the  proportions  of  this  element  varied,  stated  in  units 
of  hundredths  of  total  length  (including  caudal),  from  0.245  to  0.375,  No.  12685  having  it 
30.    An  equally  wide  variation  iu  the  European  fish  is  recorded  by  Parnell.1 

The  Pleuroneetes  elongatus  of  Yarrell  is  uot  nearly  so  elongated  as  No.  2HMil«  (the 
figure  of  Couch  has  height  about  0.275);  and  since  no  other  diagnostic  characters  have  been 
described,  we  place  it  without  hesitation  in  the  synonymy  of  O.  cynoglossus. 

(2)  Height  of  caudal  peduncle. — This  element  is  subject  to  very  slight  variation,  meas- 
uring usually!). 07  of  total  iu  botli  European  and  American  specimens.  The  most  elongate 
slender  forms  have  it  slightly  narrower.  In  No.  126S5  it  measures  0.06,  and  0.065  in  No. 
21001  b. 

(3)  Length  of  head.— This  varies  from  0.15  to  0.175.  In  No.  12685  the  length  is  0.15, 
and  in  the  European  specimens  0.15  and  0.1575  (('hristiania  specimen).  The  smallest  pro- 
portion is  represented  by  specimens  from  Massachusetts  Bay  and  Halifax. 

(4)  Teeth. — Iu  number  these  are  extremely  variable.  No.  12GS5,  according'  to  Gill,  had 
on  the  blind  side  17  above  and  20  below,  on  the  eyed  side  6  above  and  7  below.  A  Salem 
specimen,  larger  and  older,  had  on  the  blind  side  above  20,  below  28,  on  the  eyed  side  above 
13,  below  14.  In  young  individuals  the  teeth  present  the  characters  described  by  Gill,  hav- 
ing the  teeth  on  the  eyed  side  conical  and  separated.  This  peculiarity  disappears  with  age, 
all  large  specimens  showing  closely  set  incisorial  teeth  upon  both  sides  of  each  jaw. 

(5)  Length  of  pectoral. — This  is  extremely  variable  within  limits  of  0.09  and  0.14.     This 
measurement  refers  to  the  fin  upon  the  colored  side.     Its  shape  is  also  variable;  it  is  some 
times  pointed,  sometimes  obtuse,  owing  to  difference  in  comparative  length  of  the  upper 
rays.     It  is  usually  black,  with  a  narrow  whitish  tip.     The  number  of  rays  varies  from  9 
to  14. 

(0)  Length  of  rentrah. — This  is  also  extremely  variable  on  both  sides.  The  range  ou 
the  blind  side  is  0.0475  to  0.07,  and  ou  the  eyed  side  0.056  to  0.0775.  The  difference  be- 
tween the  length  of  the  two  fins  upon  the  same  individual  varies  from  0.0025  to  0.0155. 

(7)  Contour  of  lateral  line. — Iu  some  individuals  this  is  essentially   straight,  in  others 
considerably  arcuated  above  the  pectoral.     This  appears  to  be  an  individual  variation. 
The  two  European  specimens  show  a  perceptible  difference  in  this  respect.     In  his  diag- 
nosis of  Pleuronectes  cynoglossus,  Dr.  Giinther  states  that  the  lateral  line  is  straight  with 
out  curve. 

(S)  Position  of  the  eyes. — Dr.  Giinther  states  that  in  P.  elongatus  the  upper  eye  is  in 
advance  of  the  lower.  This  is  doubtless  epioted  from  Yarrcll.  Neither  the  figure  of  Yar- 
rell nor  that  of  Couch  indicates  any  such  character. 

(!l)  .Vfvf/r.v  in  lateral  line.— The  number  ou  the  blind  side  ranges  from  109  to  150,  on  the 
eyed  side  from  110  to  140,  there  being  no  relation  between  the  different  sides  of  the  same  fish.

DEEP-SEA   FISHES    OF    THE    ATLANTIC    BASIN. 


(10)  Radial  formula. — In  the  dorsal  this  ranges  from  102  to  120;  in  the  anal  from  87  to 
100.  There  is  no  apparent  relation  between  the  number  of  rays  and  the  relative  propor- 
tions of  height  and  length  of  body.  A  large  number  of  rays  in  the  dorsal  is  usually  accom- 
panied by  a  relatively  large  number  in  the  anal. 

(11)  Transverse  rows  of  scales. — Their  number  above  and  below  the  lateral  line  is  nearly 
equal.  The  range  is  about  from  10  to  50.  There  appears  to  be  no  relation  of  number  of 
transverse  rows  to  comparative  height  of  body. 

The  thermal  range  of  the  species  appears  to  be  defined  nearly  by  the  limits  31°  and 
45°  F. 

Dr.  Giinther  suggests  that  the  fish  first  cited  by  Fabricius  (Fauna  Grcenlandica,  p. 
103),  under  the  name  of  Pleuroneetes  cynoglossus,  and  subsequently  named  by  him  Pleura 
nectes  pinguis  (Afhandling,  Kougel.  Danske  Videnskabernes  Selskabs,  Naturvid.  og  Math., 
Copenhagen,  vol.  1,  1821,  p.  15),  is  probably  identical  with  this  species.  The  true  relations 
of  the  Greenland  fish  have  already  been  pointed  out  by  Professor  Gill  (Proc.  Acad.  Nat. 
Sci.  Phila.,  1801,  p.  218),  as  well  as  the  curious  misapprehension  by  which  the  synonymy  of 
P. pinguis  and  the  halibut  has  been  confounded. 

The  following  tables  give  detailed  measurements  of  23  specimens:

A  single  specimen  of  the  pole  flounder  was  obtained  by  the  Blake  from  station  343, 
39°  45'  20"  X.  lat.,  70°  55'  W.  Ion.,  in  732  fathoms.  The  occurrence  of  this  species  at  such 
immense  depths  is  noteworthy,  since  the  Fish  Commission  in  the  same  year  obtained  it  at 
a  depth  of  120  fathoms,  in  almost  the  same  latitude,  and  within  one  minute  of  the  same 
longitude  (station  876).  Specimens  were  also  taken  by  the  Blalcefrom  station  cccxxxiv. 
in  38  20'  30"  N.  lat.,  73  26'  40"  W.  Ion.,  at  a  depth  of  395  fathoms ;  from  station  ccoxxxii,

DISCUSSION   OF    SPECIES    AND   THEIR   DISTRIBUTION.  435 

The  halibut  were  once  very  abundant  in  Massachusetts  Bay,  but  are  now  found chieflj  al 
a  depth  of  100-300  fathoms  on  the  slopes  of  the  outer  banks,  where  they  are  soughl  by  a 
large  Beet  of  Gloucester  fishing  schooners.     Individuals  are  occasionally  taken  near  the 
shore.      In  1875  one  weighing  about  200  pounds  was  caught  l>y  a  dory  fisherman  off  Halt 
way  Rock,  Salem  Barbor,  and  one  still  larger  in  Gloucester  Harbor,  in  August,  1878. 

The  New  London  halibut  smacks  obtain  many  halibut  on  the  south  part  of  Georges 
Banks  and  the  neighboring  shoals.      An  individual  was   taken,  years  ago,  on  the  outei  side 

of  Fishers  Island,  Connecticut.  The  halibut  may.  in  all  probability,  be  found  to  be  abun- 
dant on  I  he  edge  of  tin'  ec nit i lien tal  slope  south  of  Cape  Cod,  since  here  have  been  recent  ly 
obtained  nearly  all  the  species  most  constantly  associated  on  the  northern  halibut  grounds 
on  the  outer  edges  of  La  Have,  browns.  Sable  Island,  and  other  banks  oft'  the  coast  of 
Nova  Scotia  and  Newfoundland.

teriorly on  the  upper  jaw,  those  of  the  outer  series  decreasing  in  size;  a  pair  of  strong 
canines  in  the  inner  series  in  front,  the  others  very  small;  a  series  of  strong,  distant  teeth 
on  lower  jaw.  (iill  rakers  short,  thick,  and  strongly  dentate.  Fins  naked.  Dorsal  and

Color,  brownish,  or  yellowish  gray. 

An  Arctic  species  frequently  brought  in  by  the  halibut  fishing  schooners  of  Glouceoter. 
Its  range  extends  as  far  south  as  the  gully  between  be  Have  and  browns  banks  ami 
Georges  banks.  A  young  specimen,  1  <».">  mm.  in  length  (I).  91 ;  A.  72),  was  trawled  by  the

species  also  occurs  in  deep  water  off  Norway,  and  a  young  one  was  taken  by  the  Norwegian 
North  Atlantic  Expedition,  southwest  of  bear  Island,  in  147  fathoms.  Unlike  adult  indi- 
viduals, the  young  have  the  blind  side  colorless.

narrow,  sharp  ridge,  the  diameter  of  the  orbit  nearly  one-fourth  of  the  length  of  the  head. 
Upper  jaw  with  very  numerous,  small,  close  set  teeth  laterally,  and  4  or  5  canines  in  front; 
the  lateral  teeth  abruptly  smaller  than  the  anterior;  lower  jaw  with  7  to  10  teeth  on  either 
side.  Maxillary  narrow,  reaching  past  vertical  from  middle  of  pupil,  its  length  two  and 
one-fourth  times  in  that  of  head.  Scales  weakly  ctenoid  or  cycloid,  over  90  in  lateral  line. 
Gill  rakers  thick  and  rather  long,  about  8  below  angle.  Dorsal  low,  beginning  over  front 
of  eye,  some  of  the  anterior  rays  exserted,  the  longest  rays  behind  middle  of  fin,  their 
length  not  quite  half  that  of  head.     No  anal  spiue. 

Radial  formula:  D.  72-86;  A.  59-76. 

Color,  brownish  gray,  mottled;  1  large  black  ocellse,  each  surrounded  by  a  lighter  mar- 
gin; 2  behind  middle  of  body,  1  below  dorsal,  and  1  above  anal;  2  smaller  spots  near  last 
rays  of  dorsal  and  anal. 

This  is  a  well-marked  species,  known  for  many  years  as  an  inhabitant  of  moderate 
depths  along  the  coast  from  Florida  north  to  Massachusetts.  The  northern  limit  of  its  range 
is  marked  by  the  capture  of  a  single  small  individual  in  1877,  off  the  mouth  of  Salem  Harbor. 

It  is  not  properly  a  deep-sea  species,  but  is  included  in  the  list  on  account  of  its  occa- 
sional capture  at  the  hundred  fathom  line. 

The  Fish  Hawk  obtained  a  single  individual  (Cat.  No.  20078,  U.  S.  N.  M.)  from  station 
873,  ia  40°  02'  N.  lat.,  70°  57'  W.  Ion.,  at  a  depth  of  100  fathoms;  and  the  Albatross  took  it 
from  station  2307,  in  35°  42'  N.  lat.,  74°  54'  30"  W.  Ion.,  at  a  depth  of  43  fathoms;  from 
station  2313,  in  32°  53'  N.  lat.,  77°  53'  W.  Ion.,  at  a  depth  of  99  fathoms;  from  station  2421, 
in  37°  07'  N.  lat.,  74°  34'  30"  W.  Ion.,  at  a  depth  of  64  fathoms;  Cat.  No.  28801,  U.  S.  N.  M., 
from  Buzzards  Bay;  and  a  single  specimen  from  station  2297,  in  35°  58'  N.  lat.,  74°  53'  W. 
Ion.,  at  a  depth  of  49  fathoms. 

Giinther  enumerates  other  species  of  Paralichthys  from  deep  waters,  namely,  Para- 
lichthys Hectoris,  (Giinther,)  from  150  fathoms,  off  New  Zealand;  P.  bbops,  (Hector,)  off

The  height  of  the  body  is  contained  twice  in  its  total  length,  without  caudal,  and  is 
equal  to  twice  the  distance  of  the  origin  of  the  \  entral  from  the  snout.  The  height  of  the 
caudal  peduncle  is  one  ninth  of  the  standard  body  length. 

The  length  of  the  head  is  two-sevenths  of  the  standard  length,  and  three  times  the 
diameter  of  the  eye.  Width  of  interorbital  ana  almost  imperceptible.  Mandible  reaching 
to  middle  of  pupil  of  lower  eye,  its  length  equal  to  half  that  of  the  head.  Upper  jaw  con- 
tained LM  times  in  length  of  head. 

The  dorsal  tin,  beginning  almost  over  the  anterior  margin  of  the  eye.  is  composed  of 
about  68  rays,  the  longest  of  which  are  the  second  and  third,  which  are  contained  twice  in 
the  greatest  height  of  the  body,  and  which  are  almost  twice  as  long  as  the  length  of  the 
base  of  the  triangular  division  of  the  tin  to  which  they  belong. 

The  anal  fin  is  made  up  of  54-56  simple  rays,  of  which  the  posterior  ones  are  largest, 
as  they  are  also  in  the  main  portion  of  the  dorsal.  It  begins  close  to  the  vent,  at  a  dis- 
tance from  the  snout  equal  to  the  length  of  the  elongated  sinistral  ventral. 

The  caudal  is  pedunculate,  its  middle  rays  somewhat  elongate,  giving  it  a  wedge  shaped 
outline. 

The  pectoral  of  the  colored  side  is  subtriangular,  its  length  contained  live  and  one- 
half  times  in  the  standard  length. 

The  ventrals  are  composed  of  six  rays,  that  upon  the  colored  side  much  produced  in 
its  anterior  portion,  its  length  more,  than  three  times  that  of  its  mate. 

Radial  formula:  D.  69;  A.  56;  P.  11;  V.  6;  B.  7.     Lateral  line  48  (in  straight  portion). 

Color  on  the  left  side  purplish  brown,  speckled  with  dark  brown,  and  with  three  large 
ocellated  subcircular  spots,  nearly  as  large  as  the  eye,  with  white  center,  dark  iris,  narrow 
ligh.1  margin,  and  a  brown  encircling  outline.  They  are  arranged  in  the  form  of  an  isosceles 
triangle,  the  spot  mat  king  the  apex  being  upon  the  lateral  line,  near  the  base  of  the  can 
dal  peduncle,  the  others  distant  from  the  lateral  line,  on  cither  side,  a  space  equal  to  their 
own  diameters,  the  lower  one  nearly  reached  by  the  tip  of  the  elongate  ventral.  On  the 
blind  side  white.     Fins  blotched  with  dark  brown.

Extreme  length  of  specimen  described,  117  millimeters.  No.  37343,  Gulf  of  Mexico, 
Albatross  station  2380,  60  fathoms. 

The  height  of  the  body  (50  millimeters)  is  about  2L  times  in  its  total  length  (without 
caudal),  and  is  equal  to  about  4i  times  the  height  of  the  tail  (11)  and  about  9  times  its 
thickness  (54). 

The  scales  are  ovate,  strongly  ctenoid,  the  largest  about  3  millimeters  in  diameter;  the 
diameter  less  than  half  that  of  the  eye.  The  scales  are  firmly  fixed;  there  are  06  scales  in 
the  lateral  line  (on  the  colored  side),  19-21  of  these  in  the  curved  portion,  which  is  bold  and 
sharply  defined;  and  19  above  and  23  below  the   lateral   line  at  broadest  part  of  body. 

The  length  of  the  head  (29  millimeters)  is  one  fourth  that  of  the  body,  and  3{j  times  the 
diameter  of  the  eye  (8);  the  interorbital  space  is  very  narrow,  scaleless,  its  width  equal  to 
one-eighth  diameter  of  eye.  The  length  of  mandible  (10  millimeters)  is  twice  the  diameter 
of  the  eye;  the  length  of  maxillary  (13  millimeters)  less  than  half  that  of  head. 

The  dorsal  fin  begins  upon  the  snout,  npon  the  blind  side,  and  in  advance  of  the.  eyes; 
its  greatest  height  about  equal  to  length  of  maadible.  It  is  composed  of  93  simple  rays. 
The  anal  begins  under  the  axil  of  the  pectoral,  its  longest  ray  (equal  to  longest  in  dorsal) 
equals  or  slightly  exceeds  half  the  distance  of  its  anterior  ray  from  the  snout.  It  is  cum 
posed  of  73  simple  rays. 

The  caudal  is  subsessile.  composed  of  17  rays;  its  length  (24  millimeters)  a  little  less 
than  half  the  height  of  body,  and  equal  to  length  of  head  without  snout. 

The  pectorals  are  inserted  considerably  below  the  origin  of  the  lateral  line,  close  to  the

PLATOPHRYS  NEBULARIS, Jordan  and  Gilbert. 

Platophrya  nebularia,  Jordan  and  Gilbert,  Proo.  U.  S.  Nat.  Mus.,  vn,  31,  June  3,  1884. 

Body  ovate,  deep  anteriorly,  the  profile  descending  steeply,  rendered  abruptly  concave 
in  front  of  interorbital  space  by  the  conspicuously  projecting,  short  snout.  Mouth  very 
small  and  oblique,  the  maxillary  reaching  vertical  from  front  of  lower  eye,  3|  in  head;  tip 
of  lower  jaw  entering  the  profile.  Teeth  tine,  conical,  in  two  series  in  the  upper  jaw,  one 
in  the  lower;  those  of  the  outer  row  in  upper  jaw  larger  and  more  widely  separated  than 
those  of  the  inner  series. 

Snout  very  short,  about  one-fifth  head,  equaling  interorbital  width.  Interorbital  space 
narrow,  deeply  concave,  closely  scaled.  Eyes  large,  the  lower  in  advance  of  upper,  its 
diameter  3§  in  head.  Gill  rakers  obsolete,  7  rudiments  on  horizontal  branch  of  anterior 
arch. 

Scales  moderate,  not  extending  on  the  tins,  those  on  colored  side  ctenoid,  those  on 
blind  side  smooth.  Arch  of  lateral  line  short  and  high,  its  base  contained  4A  to  5  times  in 
the  straight  portion. 

Dorsal  beginning  opposite  anterior  nostril,  the  rays  nearly  uniform  in  length,  the  long- 
est about  half  head.  Pectoral  of  colored  side  4f  in  length.  Ventral  of  colored  side 
beginning  under  middle  of  lower  eye.  with  <>  rays;  the  right  ventral  with  5  rays. 

Head  4  in  length;  depth  li. 

Radial  formula:  I >.  85;  A.  64;  L.  lat.  To  (pores). 

Color,  in  life,  light  grayish  with  reddish  tinge,  covered  with  small  round  spots  of  darker 
gray  and  with  lighter  rings  inclosing  spaces  of  the  ground  color.  Vertical  tins  similarly 
colored,  with  a  small  black  spot  near  base  of  each  ninth  or  tenth  ray.  Two  black  spots  on 
median  line  of  body  divide  the  length  into  nearly  equal  thirds;  some  other  small  black 
spots  scattered  over  colored  side.    [Jordan  and  Gilbert.) 

The  specimens  before  us  agree  in  all  particulars  with  Jordan  and  Gilbert's  description, 
save  in  trifling  variations  in  number  of  tin  rays  and  in  the  fad  that  in  large  specimens  the 
dilations  of  the  scales  are  absent.  In  three  specimens  of  medium  size,  the  lirst  ray  of  the 
pectoral  of  the  colored  side  is  elongated,  in  one  considerably  so.

CITHARICHTHYS  ARCTIFRONS,  Goode.     (Figures  :!66,  A,  B.) 

Citharichthys  arctifrons,  Goot>e,  Proc.  U.  S.  Nat.  Mus.,  in,  1880,  oil,  472. — Goode  ami  Bean,  Bull.  Mus.  Comp. 
Zool.,  x,  194.—  GCnther,  Challenger  Report,  xxn,  1887,  165. 

The  height  of  the  body  (37)  is  about  three-eighths  of  its  total  length  (without  caudal), 
and  is  equal  to  about  4  times  the  height  of  the  tail  (0)  and  about  5  times  its  thickness  (7). 

The  scales  are  irregularly  polygonal,  cycloid;  the  largest  about  6  millimeters  in  diam- 
eter; the  diameter  (5)  nearly  equal  to  that  of  the  eye.  The  scales  are  flexible,  loosely 
arranged,  and  very  easily  detached,  so  that  it  is  difficult  to  secure  a  specimen  in  good  order. 
Small  scales  on  the  rays  of  the  ventral  fins.  There  are  40  scales  in  the  lateral  line  (on  the 
colored  side),  which  is  sharply  defined  and  straight,  and  7  or  8  above  and  the  same  number 
below  the  lateral  line  at  the  broadest  part  of  the  body. 

The  length  of  the  head  (24-24J)  is  about  one-fourth  that  of  the  body,  and  A  times  the 
diameter  of  the  eye  (0).  The  interorbital  space  (1)  is  very  narrow,  equal  to  the  difference 
in  the  distances  from  snout  to  lower  eye  (4)  aud  snout  to  upper  eye  (5).  The  leugth  of  man 
dible  (10-104J  is  about  double  the  latter  distance;  the  length  of  the  maxillary  (7-74J  slightly 
more  than  the  greatest  width  of  the  body. 

The  dorsal  fin  begins  niton  the  snout,  above,  the  anterior  margin  of  the  upper  eye.  Its 
greatest,  height  (13-15)  is  about  three  times  the  distance  of  its  anterior  ray  from  the  snout. 
It  is  composed  of  82  to  S3  simple  rays.  The  anal  begins  under  the  axil  of  the  pectoral,  its 
greatest  height  (14-15)  equal  to  or  slightly  exceeding  half  the  distance  of  its  anterior  ray 
from  the  snout.     It  is  composed  of  67  simple  rays. 

The  caudal  is  subsessile,  triangular,  of  16  rays;  its  length  about  equal  to  that  of  the 
head.  In  dorsal,  anal,  and  caudal  the  rays  appear  to  project  beyond  the  connecting  mem- 
brane half  or  two-thirds  of  their  own  length. 

The  pectorals  are  inserted  far  below  the  lateral  line  and  close  to  the  gill  opening.  The 
pectoral  on  the  colored  side  is  composed  of  more  rays  (9-10)  than  that  of  the  blind  side  (7), 
its  length  (17-19)  being  about  double  that  of  its  mate  (7-9).  The  ventrals  are  composed  of 
4  rays. 

Color  dirty  light  brown.

U.  S.  X.  M.,  from  station  878,  in  39°  55'  N.  lat.,  70°  54'  15"  W.  Ion.,  at  a  depth  of  142J 
fathoms;  Cat.  No.  26127,  U.  S.  X.  M.,  from  station  873,  in  40°  02'  N.  lat.,  70°  57'  W.  Ion.,  at

70°  54'  18"  YY\  Ion.,  at  a  depth  of  126  fathoms.  Numerous  specimens  taken  by  the  Fish 
Hawk  on  September  4,  1880,  ranged  in  length  from  90  to  140  meters  The  females  were 
fall  of  ripe  spawn.  It  is  not  probable,  therefore,  that  the  average  size  of  the  species  is 
much  greater  than  that  of  the  specimens  described. 

The  Blake  secured  examples  as  follows:  Eight  young  individuals,  the  longest  measuring 
2  inches,  from  station  cccxni,  off  Charleston,  S.  C,  in  75  fathoms;  3  specimens,  badly  mu- 
tilated, from  station  cecxxxvi,  in  38°  21'  N.  lat.,  73°  32'  W.  Ion.,  at  a  depth  of  197  fathoms; 
a  large  one  from  station  COCXI,  in  39°  59'  30"  N.  lat.,  70°  12'  \Y.  Ion.,  at  a  depth  of  143 
fathoms;  and  others  from  station  crcxiv,  in  32  =  24'  N.  lat.,  78°  44'  W.  Ion.,  at  a  depth  of 
142  fathoms,  and  from  station  cccxxxv,  in  38c  22'  05"  N.  lat.,  73°  33'  40"  W.  Ion.,  at  a  depth

CITHARICHTHYS  UNICORNIS,  Goode.     (Figure  369,  A,  B.) 

Cilharichthys  unicornis,  Goode,  Proc.  U.  S.  Nat,  Mas.,  in,  1880,  342;  ibid,  472.—  Joki.an  and  Gilbert,  Bull, 
xvi,  U.  S.  Nat.  Mus.,  818. — GDnther,  Challenger  Report,  xxn,  1887,  166. 

The  greatest  height  of  the  body  (47)  is  slightly  less  than  its  length,  and  is  about  4J 
times  its  least  height  at  the  tail  (11).    The  body  is  much  higher  than  in  G.  arctifrons,  its

greatest  lieighl  over  the  pectorals,  Hie  contours  then  descending  in  almost  straight  lines  to 
the  base  of  the  tail.  The' thickness  of  the  body  (6)  is  less  than  in  ft  aretifrons,  being  con- 
tained Dearly  17  times  in  the  standard  length. 

The  scales  are  thin,  deciduous,  smaller  than  in  ft  aretifrons.    There  arc  about  in 

scales  in  the   lateral  line,  which  is  slightly  curved    over  the    pectoral,  and,  as  nearly  as  can 

he  determined  in  the  denuded  specimens  before  me,  about  12  rows  above  and  12  below  the 
lateral  line  at  the  broadest  pail  of  the  body. 

The  length  of  the  bead  (25)  is  one-fourth  of  the  standard  length  and  about  3  times 

the  diameter  of  the  eye  i!)),  or  the  distance  from  the  snout  to  the  upper  eye  (9).  The  inter 
orbital  space  is  w  ide  |  1 1,  equal  to  the  length  of  the  snout,  and  diagonally  crossed  by  a  strong 
ridge,  a  continuation  of  two  ridges  which  form  the  upper  boundary  of  t  he  lower  and  the 
lower  boundary  of  the  upper  orbit. 

The  length  of  the  maxillary  (11)  is  less  than  half,  that  of  the  inaudible  (13)  more  than 
half,  that  of  the  head.  The  teeth  are  minute,  in  single  rows,  closely  set  in  the  jaws,  some- 
what stronger  upon  the  blind  side.  A  strong  short  spine  above  the  snout,  at  the  anterior 
termination  of  the  ridge  at  the' lower  margin  of  the  upper  eye.  Hence  the  specific  name 
unicornis. 

The  dorsal  fin  begins  at  the  side  of  the  preorbital  spine,  its  anterior  rays  being  slightly 
crowded  over  upon  the  blind  side.  It  is  composed  of  73  to  75  simple  rays.  Its  greatest 
height  (13)  is  half  the  length  of  the  head. 

The  distance  of  the  anal  from  the  snout  (33)  is  one  third  of  the  standard  length.  The 
number  of  rays  is  (ill;  their  longest  (13)  equal  in  length  to  the  longest  dorsal  rays. 

The  caudal  is  pointed,  triangular,  subsessile;  its  length  (22)  twice  that  of  the  maxillary 
(11)  and  two  thirds  the  distance  from  the  snout  to  the  anal  (.'>•'!).  The  pectorals  are  inserted 
far  below  the  lateral  line.  The  pectoral  of  the  colored  side  is  twice  as  long  (18)  as  the 
diameter  of  tin'  eye,  that  of  the  blind  .side  as  long  (13)  as  the  longest  dorsal  rays.  The  for- 
mer is  composed  of  10  rays,  the  latter  of  4. 

The  length  of  the  ventrals  (11)  is  half  that  of  the  caudal.  They  are  asymmetrically 
placed,  as  is  described  under  the  generic  diagnosis.

446  DEEP-SEA   FISHES    OF    THE    ATLANTIC    BASIN. 

The  type  specimen  (Cat.  No.  26003,  IT.  S.  N.  M.),  69  millimeters  in  length,  was  taken 
by  the  Fish  SawJc  from  station  870,  in  40°  02'  36"  N.  lat.,  70°  22'  58'  W.  Ion.,  at  a  depth 
of  155  fathoms,  and  from  station  871,  in  40°  02'  54"  N.  lat,,  70°  23'  40"  W.  Ion.,  at  a  depth 
of  115  fathoms.  The  A Ibatross  obtained  examples  from  station  2318,  in  24°  25' 45"  N.  lat. 
81°  46'  W.  Ion.,  at  a  depth  of  45  fathoms;  from  station  2401,  in  28°  38'  30"  N.  lat.,  85  52; 
30"  W.  long.,  at  a  depth  of  142  fathoms;  from  station  2402,  in  28°  36'  X.  lat.,  85°  33'  30" 
W.  Ion.,  at  a  depth  of  111  fathoms;  from  station  2404,  in  28c  44'  N.  lat.,  85<:  16'  W.  Ion., 
at  a  depth  of  60  fathoms;  and  from  station  2417,  in  33°  18'  30"  X.  lat.,  77:  07'  \Y.  Ion.,  at 
a  depth  of  95  fathoms. 

CTTHAKIt'HTIIYS  MICROSTOMUS,  Gii.l. 

Citharickthys  microstomus,  Gill,  Proc.  Acad.  Nat.  Sci.  Phila.,  1864,  223. 

Citharichthys  spilopterus,  Jordan  and  Gilbert,  Bull.  xvi.   1".  s.  Nat.   Mus.,  817  mot  iHinther.) 

The  height  of  the  body  enters  about  2§  times  (.36-.37)  in  the  extreme  length;  that  of 
the  caudal  peduncle  about  11  times.  The  head  forms  a  tilth  of  the  length,  is  rather 
abbreviated,  scarcely  sinuous  above  the  eves,  blunt  at  the  snout,  which  scarcely  exceeds  a 
seventh  of  the  head's  length,  and  the  rostral  area  is  rhombic  and  not  higher  than  long. 
The  eyes  are  even;  the  longitudinal  diameter  contained  about  .'!-;  times  (.l»5Ai  in  the  head's 
length.  The  mouth  is  rather  small,  the  length  of  the  upper  jaw  only  equaling  one  fourth 
of  the  length,  and  that  of  the  lower  two  tilt  lis  of  the  head's  length.  The  teetli  are  very 
small  and  close  together,  larger  in  front.  The  dorsal  commences  above  the  front  of  the 
orbit  and  is  highest  and  convergent  near  the  fortieth  ray,  which  equals  about  one  tenth  of 
the  total  length;  the  anal  is  highest  at  about  the  twenty-fifth  ray,  and  is  as  high  or  even 
higher  than  the  dorsal.  The  caudal  is  rounded  behind  and  forms  about  one-sixth  of  the 
length.  The  pectoral  tins  are  unequally  developed,  that  of  the  dark  side  being  prolonged 
and  contained  only  6sj  times  in  the  total  length,  while  that  of  the  white  side  only  equals 
one-tenth  of  the  same;  the  rays  are  also  simple.  The  ventral  tins  are  also  unequally 
developed,  the  rigid  being  on  the  abdominal  ridge  at  its  origin,  rather  in  advance  of  the 
opercular  margin,  ami  with  its  longest  rays  contained  about  14  times  in  the  total  length; 
stretched  backwards  it  extends  to  the  second  anal  ray ;  the  tin  on  the  white  side  is  more 
advanced,  wider,  and  its  rays  longer,  contained  less  than  12  times  in  the  length,  and 
extends  backward  to  nearly  the  third  anal  ray. 

Eadial  formula:     D.  81;  A.  58;  C.  4,  6,  5,  3;  P.  10;  V.  6. 

The  scales  are  large,  angular  behind,  covered  with  smaller  ones,  especially  near  the 
point  of  conjunction  of  contiguous  ones,  where  alone  they  are  developed  on  the  blind  side; 
the  scales  of  the  eyed  side  are  mostly  minutely  ciliated  behind,  unarmed,  however,  near 
the  lateral  line,  the  scales  of  which  last  are  quadrate  and  mostly  covered;  the  scales  of 
the  blind  side  are  less  angular  behind  and  unarmed.  The  lateral  line  runs  through  about 
42  scales,  while  of  longitudinal   rows  there   are  10  above  and  14  below   the  lateral  line. 

The  color  is  uniform  reddish  brown.  A  single  specimen,  little  more  than  3  inches 
long,  was  first  obtained  by  Prof.  Baird  at  Beeseley's  Point.  It  is  especially  distinguished 
from  its  California  relative,  0.  sordida,  by  the  shorter  snout,  small  mouth,  and  large  settles, 
0.  sordida  having  about  58  scales  pierced  by  the  lateral  line  and  18  rows  above  the  lateral 
line.  Notwithstanding  this  great  disparity  in  the  size  of  the  scales  and  mouth  C.  micro- 
stomus  appears  to  agree  in  most  respects  with  the  California  fish,  as  well  as  generically 
with  Citharichthys  spilopterus  of  Giinther,  a  species  inhabiting  the  Gulf  of  Mexico. 

As  the  name  Citharichthys  was  probably  introduced  a  short  time  before  Orthopsetta,  pro- 
posed for  the  Psettichthys  sordidus,  anil  was  framed  for  a  species  related  to  that  type,  that 
name  must  be  adopted  if  the  0.  sordida  is  not  regarded  as  generically  distinct. 

We  may  here  remark  that,  although  I  have  referred  the  Platessa  quadrocularis  of  Storer 
to  the  genus  Ckcenopsetta  (C.  oblonga),  it  is  possible  that  it  may  not  truly  belong  to  that 
genus,  as  the  dorsal  and  anal  fins  are  represented  as  increasing  backwards  till  near  their 
ends,  and  the  anterior  dorsal  rays  are  free  at  their  ends;  but  as  the  species  agrees  so

closely  in  Other  external  characters  we  feel  eoinpelled  to  retain  it  in  that  genus  for  the  pres- 
ent at  least. 

A  specimen  (D.  77;  A..  61;  7.6;  L.  lat.  10)  was  taken  by  the  Albatross  from  station 
I'll  7.  in  33°  18'  30"  N.  lat..  77    i>7'  W.  Ion.,  off  Cape  Fear,  at  a  depth  <>t'  95  fathoms.

Oitharichtkya  spHopterut,  GOnther,  Cat.  Fish.  Brit.  Mus.,  iv,  421. 

The  height  of  the  body  is  two-fifths  of  the  total  length  (without  caudal),  the  length  of 
i In'  head  two-sevenths.  Seales  of  the  lateral  line  subquadr angular;  lateral  line  nearly 
straight,  gently  descending  anteriorly.  Snout  with  the  .jaws  equal  in  front,  rather  longer 
than  the  eye,  the  diameter  of  which  is  one-sixth  of  the  Length  of  the  head.  The  maxilla  i  \ . 
the  length  of  which  is  contained  twice  and  two-thirds  in  that  of  the  head,  extends  beyond 
the  middle  of  the  orbit.  Anterior  teeth  in  the  upper  jaw  widely  set,  much  larger  than  the

Body  sinistral;  general  form  that  of  an  ellipse,  the  caudal  extremity  being  considerably 
produced.  Its  height  is  contained  2j  times  in  its  length,2|  times  in  itslength  to  the  end  of 
the  caudal  fin,  and  is  4  times  the  height  of  the  tail  at  its  lowest  portion.  Its  height  at  the 
ventrals  is  3  times  as  great  as  at  the  tail.  Its  greatest  width  is  equal  to  the  diameter  of  the 
upper  orbit. 

The  scales  on  the  cheek  of  the  blind  side  are  arranged  in  13  series;  those  upon  the 
nape  and  hiterorbital  space  of  the  eyed  side  are  smaller  than  upon  the  body.  The  scales  on 
the  body  arc  large,  thin,  deciduous,  and  cycloid.  There  are  57  scales  in  the  lateral  line, 
54  of  which  are  tube-bearing.  Lateral  line  straight,  and  over  the  axis  of  the  body,  save  in 
its  anterior  fourth,  within  which  it  slightly  ascends  witli  a  very  gentle  curve,  to  the  upper 
angle  of  the  gill  opening.  Above  the  lateral  line  are  13  scales;  below,  22.  The  vertical 
tins  are  scaly  two-thirds  of  the  distance  to  their  tips. 

The  head  is  short,  its  length  being  contained  3jj  times  in  the  standard  body  length,  4 \ 
times  in  the  total  length,  and  lij  times  in  the  greatest  height  of  body.  The  snout  is  short; 
its  length,  slightly  less  than  the  diameter  of  the  lower  eye,  is  contained  5  times  in  the  length 
of  the  head.  Mouth  rather  large,  the  upper  edge  somevt  hat  curved,  its  cleft  very  oblique, 
the  maxillary  extending  to  below  the  middle  of  the  lower  eye.  The  lower  jaw  extends  to  the 
vertical  from  the  anterior  margin  of  the  upper  eye.  Length  of  the  upper  jaw  equals  one- 
third  the  distance  from  the  snout  to  the  insertion  of  the  anal.  The  lower  jaw  equals  the 
distance  from  the  tip  of  the  snout  to  the  posterior  margin  of  the  lower  eye  and  is  contained 
2J  times  in  the  length  of  the  head.  Teeth  moderate,  equally  developed  on  both  sides,  in  two 
rows  in  the  upper  jaw,  those  of  the  outer  row  upon  the  blind  side  of  the  upper  jaw  and  the 
anterior  portion  of  the  eyed  side  considerably  larger  than  those  in  the  inner  row.  The  teeth 
of  the  lower  jaw  uniserial,  almost  as  large  as  in  the  outer  row  of  the  upper  jaw. 

The  eyes  are  large,  prominent,  and  far  apart.  Their  longitudinal  diameter  equals  the 
length  of  the  snout,  and  is  contained  5  times  in  the  length  of  the  head.  Their  vertical 
diameter  is  about  three-fourths  as  great  as  their  longitudinal  diameter.  The  lower  eye  is 
far  in  advauceof  the  upper,  the  vertical  from  the  anterior  margin  of  the  upper  orbit  cutting 
the  lower  orbit  at  a  point  about  two-thirds  the  distance  from  its  anterior  to  its  posterior 
margin.  The  upper  eye  is  close  to  the  dorsal  profile,  separated  from  it  by  a  distance  equal- 
ing about  one-half  its  longitudinal  diameter.     The  iuterorbital  space  is  rlattish  and  uneven,

its  width  being  contained  I  times  in  the  length  of  the  head.  A  prominent  ridge  extends 
from  the  upper  posterior  margin  of  the  lowereye  to  the  lower  posterior  margin  of  the  upper 
eye.  i  hence  widening  and  curving  downward  to  the  upper  angle  of  t  he  branchial  aperl  lire. 
The  margin  of  the  preoperculnm  is  also  somewhat  elevated.  The  length  of  the  operculum 
is  very  slightly  greater  than  the  width  of  the  interorbital  space. 

There  are  1 1  short  and  thick  gill  rakers  ou  the  anterior  arch,  the  Longest  equal  in  Length 
to  one-tin rd  tlic  diameter  of  t  he  eye. 

The  dorsal  tin  begins  on  the  blind  side  of  the  body  in  advance  of  the  anterior  margin  of 
the  lower  eye;  its  anterior  lays  are  almost  lice,  the  longest  lays  behind  its  middle,  its 
greatest  height  equal  to  the  Length  of  the  upper  jaw. 

The  anal  is  inserted  under  the.  anterior  angle  of  the  pectoral  axilla.      Its  anterior  rays 
are  less  free  than  are  those  of  the  dorsal,  about  t  wo  thin  Is  of  I  heir  length   being  extruded 
from  their  membrane.      Its  outline  similar  to  that  of  the  dorsal,  lint  greatest    height    some 
what  less,  being  one-third  the  length  of  the  head. 

'fhc  greatest  Length  of  the  caudal  equals  the  Length  of  the  head  without  the  snout,  and 
one- fifth  of  the  body  length.  Its  middle  rays  are  somewhat  Longer  than  t  he  outer  rays,  giv 
ing  to  the  posterior  margin  the  outline  of  an  obtuse  angle. 

The  pectoral  is  inserted  at  the  tip  of  the  opercular  flap;  its  second  and  third  rays  much 
produced  in  a  filamentous  extension.  Its  greatest  length  slightly  exceeds  \h  times  that  of 
the  head.  The  pectoral  on  the  blind  side  has  no  prolonged  rays;  its  greatest  length  equal- 
ing that  <>f  the  upper  jaw. 

'fhc  ventral  on  the  eyed  side  is  inserted  on  the  ridge  of  the  abdomen  slightly  behind  its 
mate,  which  is  a  little  removed  from  the  medial  line. 

Distance  between  insertion  of  the  ventral  and  the  snout  equals  one-fourth  the  length 
of  the  body.  The  length  of  the  ventral  equals  one  third  jhat  of  the  head.  Vent  close  to 
the  origin  of  anal,  and  slightly  removed  from  the  medial  point,  of  the  body  on  the  blind 
side;  behind  it  a  small  papilla,  one  fourth  as  long  as  the  eye.

Cidor,  eyed  side,  grayish  brown;  blind  side,  somewhat  clouded  with  darker  shade. 

The  width  of  the  interorbital  space  in  the  type  exceeded  the  diameter  of  the  eye.  In 
.-.ome  smaller  ones  the  space  is  about  equal  to  the  length  of  the  eye.  while  in  still  younger 
ones   it  is  Less  than  the  diameter  of  the  eye.

angle.  The  upper  eye  is  placed  at  a  distance  from  the  dorsal  profile  equal  to  half  its  own 
diameter,  which  is  a  little  more  than  one-fifth  the  length  of  the  head,  and  is  equal  to  that 
of  its  mate.  Byes  in  the  same  vertical  and  separated  by  an  interspace  equal  to  one-fourth 
the  orbital  diameter.     Interorbital  ridge  low. 

Nostrils  on  the  line  of  the  interorbital  ridge;  the  anterior  is  equidistant  from  the  tip' 
of  the  snout  and  the  margin  of  the  upper  eye;  it  is  in  a  very  inconspicuous  tube,  provided 
with  a  slender  filament  about  one-third  the  length  of  the  snout.  The  posterior  nostril  is 
separated  from  the  anterior  one  by  a  space  equal  to  one-fifth  the  length  of  the  snout. 

Teeth  uniserial  in  both  jaws,  some  of  the  anterior  ones  in  the  upper  jaw  being  much 
larger  than  those  following,  while  those  in  the  lower  jaw  are  still  larger  than  these.  Some 
of  the  teeth  in  each  jaw  are  depressible. 

The  dorsal  fin  begins  on  the  snout,  in  advance  of  the  nostrils;  the  first  ray  longer  than 
the  second.  The  longest  rays  are  behind  the  middle  of  the  fin,  their  length  (26  millimeters) 
one  fourth  the  height  of  the  body.     Eighty  rays  compose  the  fin. 

The  anal  fin  begins  under  the  axil  of  the  pectoral.  Its  longest  rays  behind  its  middle, 
their  length  (•">()  millimeters)  greater  than  that  of  longest  dorsal  rays.     It  contains  00-01  rays. 

Caudal  with  middle  rays  produced,  the  length  of  the  median  rays  (45  millimeters) 
contained  4'  in  total  length. 

The  greatest  length  of  the  pectorals  (39  millimeters)  is  contained  5|  times  in  total 
length. 

The  ventral  of  the  colored  side  is  on  the  ridge  of  the  abdomen,  on  a  line  with  its  mate, 
which  is  slightly  removed  from  the  median  line.  Its  distance  from  snout  (56  millimeters)  a 
little  more  than  one-quarter  the  length  of  the  body.  Its  length  (23  millimeters)  equal  to 
half  the  length  of  median  caudal  rays.  The  ventral  of  the  blind  side  is  continued  by 
a  thin  membrane  to  the  vent,  which  is  slightly  distant  from  the  edge  of  the  abdomen,  and 
behind  the  origin  of  the  anal. 

Color,  grayish  brown;  the  dorsal  and  anal  fins  each  with  two  roundish  dark  blotches 
upon  their  posterior  halves,  which  are  slightly  larger  than  the  eye.  A  similar  dark  blotch 
upon  the,  middle  of  the  caudal,  sometimes  with  smaller  blotches  irregularly  placed  near  its 
outer  margin. 

Pectoral,  with  a  very  narrow  dark  band  near  its  base;  the  whole  of  its  outer  half  is 
marked  by  a  dark  blotch,  reticulated  and  mottled  with  lighter;  the  intervening  portion  is 
pearly  white,  with  dark  specks  upon  the  rays.     Blind  side  cream  colored.

The  height  of  the  body  (38)  is  about  three-eighths  of  the  total  length  (without  caudal), 
and  is  equal  to  twice  the  distance  of  the  origin  of  the  ventral  from  the  snout  (19);  its  height 
over  the  ventrals  (25)  is  about  five  times  the  longitudinal  diameter  of  the  lower  eye  (5),  the 
least  height  (8.5),  at  the  base  of  the  tail,  slightly  greater  than  the  length  of  the  lower  jaw 
(8).     Body  thin,  its  greatest  width  (5)  not  exceeding  the  longitudinal  diameter  of  the  orbit. 

Scales  subcircular,  with  irregular  outline,  about  2  millimeters  in  diameter,  or  about 
one-fourth  (1.25)  the  diameter  of  the  eye.  The  posterior  edge  of  each  of  the  scales  upon 
the  colored  side  is  pectinate  with  about  fifteen  denticulations.  The  scales  of  the  blind  side 
are  oval,  nonpectinate,  about  as  large  as  those  of  the  colored  side.  The  head  is  everywhere 
closely  thatched  with  scales,  even  to  the  edges  of  the  lips,  and  small  scales  occur  on  the 
bases  of  the  caudal,  pectoral,  and  ventral  tins,  and  upon  the  rays  of  the  vertical  fins  nearly 
out  to  their  tips.  There  are  about  23  rows  above  and  25  below  the  lateral  line  on  the  col- 
ored side,  behind  the  curve  of  the  line. 

Lateral  line  of  colored  side  strongly  bent  in  its  anterior  part  over  the  base,  and  anterior 
two-thirds  of  the  pectoral  fin.  There  are  about  92  scales  in  the  lateral  line,  72  of  them  in 
its  straight  portion.  The  arc  of  the  curved  portion  of  the  lateral  line  (12)  is  slightly  more 
than  double  the  distance  of  its  highest  portion  above  the  line  of  the  straight  portion  of  the, 
line  were  it  continued  (5).  The  curve  of  the  line  is  very  peculiar,  having  two  angles,  that 
nearest  the  head  being  more  obtuse.  The  lateral  line  ou  the  blind  side  is  nearly  straight, 
slightly  ascending  above  the  abdominal  cavity. 

The  length  of  the  head  (20)  equals  one-fifth  of  the  standard  length,  and  four  times 
diameter  of  eye,  or  length  of  operculum  (5).  Distance  from  snout  to  margin  of  upper  eye  (5) 
much  greater  than  distance  to  lower  eye  (3),  and  less  thau  length  of  the  maxillary  (5.5),  the 
posterior  margin  of  which  passes  the  perpendicular  from  the  anterior  margin  of  the  lower 
eye.  The  width  of  the  iuterorbital  area  is  very  small,  less  thau  one-sixth  of  the  diameter  of 
the  eye.    The  length  of  the  mandible  (8)  is  two-fifths  of  the  head.

Tlif  dorsal  fin  1  if^ins,  upon  the  snoul  in  the  perpendicular  from  the  anterior  margin  of 
the  lower  eye.  It  is  composed  of  from  99  to  104  simple  rays  (in  5  specimens),  the  longest 
ol'wliirli  in  the  posterior  fourth  of  the  fin;  their  length  (9)  nearly  half  that  of  the  head. 
The  anal  fin  begins  between  the  tips  of  the  veul  ral,  close  to  the  pent,  and  under  the  inser 
tion  of  the  pectoral.  It  is  composed  of  T'.i  to  84  simple  rays,  the  longest  in  the  posterior 
fourth;  their  length  (7i  slightly  more  than  one-third  the  length  of  the  head. 

Tlic  caudal  is  sessile,  ion  in  lei  I.  t  lie  middle  rays  in  length  (17)  nearly  double  the  longest

The  young  form  of  Monolene  described  by  Goode  under  the  name  Thyris  pellucidus 
(Fig.  359)  is  so  remarkably  distinct,  that  the  description  is  given  here: 

The  length  of  the  specimen  described  (No.  26005)  is  72  millimeters. 

The  height  of  the  body  (32)  is  about  one-third  of  its  length  (without  caudal),  the  least 
height  oi'  the  tail  (7)  one-fourteenth.  The  body  is  thin,  pellucid,  larval-like,  divided  into 
three  longitudinal  tracts  by  depressions  at  I  In-  bases  of  the  rows  of  interspinous  processes, 
as  in  Glyptocephalus. 

Tin;  scales  are  small,  thin,  easily  detached  (none  remain  upon  the  specimen  except  a 
tew  in  the  lateral  line).    The  number  of  transverse  rows  is  estimated  at  120,  the  number 

of  rows  above  ami  below  the  lateral  line  al  the  wiliest  portion  of  the  body  17  or  IS.  The 
scales  in  the  lateral  line  are  provided  with  a  large  central  canal.  The  lateral  line  is 
straight  on  both  side-,. 

flic  head  is  very  small:   its   length  (18)  contained   about    five  and  one-hall'  limes  iii  the

total  length  of  the  body.  The  eyes  are  small,  protruding,  tbe  upper  almost  perpendicularly 
above,  though  perhaps  slightly  posterior  to  the  lower.  The  diameter  of  the  eye  (2)  equals 
the  width  of  the  interorbital  space  (2)  anil  is  double  the  distance  (4)  from  the  snout  to  the 
upper  eye,  that  from  the  snout  to  the  lower  eye  (3)  being  intermediate.  The  nioutli  is 
small,  the  shape  of  the  opening  being  somewhat  like  that  in  Solea,  the  upper  jaw  being 
somewhat  hook-shaped.  The  length  of  the  upper  jaw  (4)  is  two-thirds  that  of  the 
mandible  (6). 

The  dorsal  commences  on  the  snout  in  advance  of  the  eye,  and  is  composed  of  !'<>  to 
102  long,  flexible,  simple  rays,  their  tips  apparently  extending  far  beyond  the  connecting 
membrane.  The  length  of  the  longest  rays  (14)  is  double  the  least  height  of  the  body  at 
the  base  of  the  tail  (7). 

The  anal  fin  originates  at  a  distance  (22)  from  the  snout  contained  four  time*  and  one- 
half  in  the  length  of  the  body.  It  is  composed  of  7G  to  81  rays,  the  longest  of  which  are  as 
long  as  the  head. 

The  pectoral  is  inserted  close  to  the  gill  opening  and  far  below  the  lateral  line  (midway 
from  the  black  stripe  upon  the  lateral  line  to  the  black  stripe  at  the  base  of  the  interspin- 
ous  processes  of  the  anal  fin).  The  pectoral  upon  the  blind  side  is  short,  its  length  (2) 
equal  to  the  diameter  of  the  orbit,  composed  of  about  four  or  five  rays;  that  upon  the  col- 
ored side  longer,  its  length  (3)  equal  to  that  of  the  snout,  and  composed  of  about  twelve 
rays.  The  ventrals  are  both  crowded  upon  the  ventral  keel,  their  bases  prolonged  upon 
the  keel,  their  tips  embracing  the  origin  of  the  anal. 

Radial  formula:  D.  96-102;  A.  76-81;  P.  12  left,  4-5  right. 

Color:  In  life  colorless,  translucent.  In  alcohol  yellowish  white.  Three  prominent 
blackish  longitudinal  stripes  or  lines  upon  the  left  side.  The  stripe  running  from  the 
branchial  cleft  to  the  base  of  the  tail  is  less  prominent  than  the  two  at  the  bases  of  the  in- 
terspinons  processes.  On  the  lateral  line  of  the  right  side  there  is  no  stripe,  though  the 
two  lateral  stripes  are  as  prominent  as  upon  the  other  side.     Eyes  black.

Height  of  the  body  (37)  is  one  third  of  the  total  length  without  the  snout,  and  equals 
4  times  the  long  diameter  of  the  eye;  it  also  equals  1§  times  the  distance  of  the  ventral 
origin  from  the  snout.  The  height  at  the  origin  of  the  ventrals  (20)  equals  about  •">  times 
the  length  of  the  lower  eye  (0).  The  least  height  at  the  base  of  the  tail  (8)  equals  four- 
tifths  of  the  length  of  the  mandible  (10).  The  body  is  thin,  its  greatest  width  (4J)  equal- 
ing one  half  the  length  of  the  eye. 

Scales  ovate  or  oblong,  smaller  than  in  M.  sessilicauda,  and  without  evident  pectina- 
tions. The  head  is  everywhere  seals  except  on  the  lips  and  the  anterior  half  of  the  snout. 
The  scaling  of  the  fins  is  essentially  the  same  as  in  M.  sessilicauda.  There  are  30  rows  of 
scales  above,  ami  32  below  the  lateral  line  on  the  colored  side. 

The  lateral  line  of  the  colored  side  is  strongly  arched  in  its  anterior  part  over  the  base 
and  anterior  third  of  the  pectoral  fin.  The  arc  of  the  curved  portion  of  the  lateral  line 
(10)  equals  24  times  the  height  of  the  curve  (4).  The  curve  is  entirely  similar  to  that  in 
.1/.  sessilicauda.  The  lateral  line  of  the  blind  side  is  nearly  straight,  very  slightly  ascend- 
ing anteriorly.  There  are  105  scales  in  the  lateral  line  to  caudal  base,  18  of  these  in  the 
curved  portion. 

The  length  ol  the  head  (24)  equals  two-ninths  of  the  standard  length,  and  2r;  times  the 
diameter  of  the  eye.  The  distance  from  the  snout  to  the  front  of  the  upper  eye  (0)  is  much 
greater  than  tin;  distance  to  the  lower  eye  (3).  The  interorbital  area  is  a  mere  narrow- 
ridge,  whose  width  (1  )  equals  only  one  ninth  of  the  length  of  the  eye  The  length  of  the 
maxilla  (8)  equals  one-third  the  length  of  the  head,  and  on  account  of  its  oblique  position 
its  hind  margin  does  not  extend  much  beyond  the  vertical  through  the  front  margin  of  the 
lower  eye.  The  length  of  the  mandible  (10)  equals  live-twelfths  of  the  head's  length.  The 
teeth  are  uniserial  ami  well  developed  on  both  sides.  The  nostrils  are  in  very  short  tubes, 
in  the  same  line  with  the  interorbital  ridge,  the  posterior  one beiug  slightly  less  distant 
from  the  lower  eye  than  the  anterior  is  from  the  tip  of  the  snout.  A  concavity  above  the 
snout. 

The  dorsal  fin  begins  upon  the  snout  on  the  blind  side  in  the  perpendicular  through 
the  front  of  the  lower  eye.  ft  contains  124  simple  rays,  the  longest  rays  being  in  the  pos- 
terior fourth  of  the  tin,  and  one  half  as  long  as  the  head.     The  anal  tin  begins  between  t he 

tips  of  the  ventrals  and  under  the  origin  of  the  pectoral.    The  vent  is  not  on  the  ventral 

outline,  but  on  the  blind  side  and  close  to  the  beginning  of  the  anal  tin.     The  anal  iscomposed

of  100  simple  rays,  the  longest  (14)  being  behind  the  middle  of  the  fin  and  slightly  longer 
than  the  longest  of  the  dorsal  (13).  Tbe  caudal  is  sessile,  rounded,  the  middle  rays  (20) 
about  one-sixth  of  standard  length  of  body.  The  pectoral  is  present  only  on  the  colored 
side,  is  inserted  close  to  the  edge  of  the  operculum,  its  length  (27)  exceeding  that  of  the 
head,  and  contained  4J  times  in  the  standard  length.  The  ventral  of  the  colored  side  is 
nearly  on  the  ridge  of  the  abdomen,  while  that  on  the  blind  side  is  mostly  lateral,  and 
slightly  larger  than  its  fellow.  The  length  of  the  left  ventral  (7)  is  about  3J  times  in  length 
of  head. 

The  color  on  the  left  side  is  light  brownish  gray:  the  fins  are  mostly  dusky  except  the 
right  ventral,  which  is  pale;  the  pectoral  and  the  eyelids  are  black. 

D.  124;  A.  100;  Y.  C;  P.  12:  scales  30-105-32  (18  in  curved  portion  of  lateral  line). 

A  single  specimen,  the  type  (xvi),  114  millimeters  long,  was  taken  by  the  Blake  off 
Barbados  in  288  fathoms,  and  another  one  (xvn)  in  the  same  locality  at  a  depth  of  218

Heterosomata  with  body  oval  or  elliptical,  and  nearly  equally  developed  above  and 
below  the  lateral  line.  Scales  small  (ctenoid  or  cycloid),  or  absent;  the  lateral  line  usually 
straight  (sometimes  double  or  triple).  The  head  small,  with  rounded,  projecting  snout,  and 
upper  jaw  more  or  less  hooked.  Opercular  bones  concealed  by  the  integument.  Eyes 
approximated,  the  upper  more  or  less  advanced;  the  opercula  concealed  by  the  scales. 
Mouth  unsynimetrical  and  rather  small  and  curved:  teeth  some  times  wanting,  generally 
confined  to  the  blind  side  of  the  jaws,  and  villiform.    Branchiostegal  rays  usually  7. 

Dorsal,  anal,  and  caudal  fins  usually  separate,  sometimes  continent.  The  dorsal  origin 
is  on  the  snout,  the  anal  under  the  pectoral;  pectorals  small  or  absent:  ventrals  small  and 
variously  developed.  Vertebrae  very  numerous,  but  unequally  distributed,  in  the  typical 
tonus  the  abdominal  or  rib  bearing  ones  being  only  8  or  0  in  number,  and  the  caudal 
about  40. 

The  family  is  well  distinguished  from  the  Pleuronectidce,  especially  so  far  as  the  Euro- 
pean and  American  species  are  concerned,  though  some  Australian  forms  are  intermediate.

APHORISTIA  PIGRA,  Goode and  Bean.     (Figure377.) 

Aphoriatia pigra,  Goode  and  Bean,  Bull.  Mas.  Comp.  Zool.,  Cambridge,  xn,  154. 

It  is  distinguished  by  its  abbreviated  form,  and  its  large,  rough,  strongly  pectinate  scales. 
The  extreme  length  of  the  type  is  98  millimeters. 

The  body  is  shorter  than  in  the  congeneric  Atlantic  species;  its  greatest  height  is  con- 
tained 3t  times  in  its  total  length,  or  three  times  in  total  without  snout. 

The  scales  are  large,  very  rough,  with  strong  horizontal  stria'  and  strongly  denticulated 
margins,  and  rather  loosely  fixed  to  the  skin;  about  65  in  a  horizontal  series,  34  in  a  trans 
verse  series.  The  jaws  and  snout  are  covered  with  small  scales.  The  length  of  the  head 
is  contained  4.^  in  total  length.  The  length  of  the  snout  is  contained  44  times  in  that  of 
the  head.  The  eyes  are  moderate  in  size,  very  close  together,  with  no  scales  between;  the 
upper  is  very  slightly  in  advance,  and  is  distant  from  the  dorsal  outline  a  space  equal  to 
its  own  short  diameter.  The  greatest  diameter  of  the  eye  is  contained  six  times  in  the 
length  <>f  the  head.  The  mouth  is  oblique,  curved,  its  posterior  angle  directly  beneath  the 
middle  of  the  lower  eye.  Length  of  gape  in  that  of  head  four  times.  The  teeth  are  feeble, 
closely  placed,  a  little  stronger  on  the  colored  side. 

The  nostril  tubular,  a  little  nearer  to  the  lower  eye  than  to  the  tip  of  the  snout. 

The  dorsal  tin  begins  at  a  point  over  the  middle  of  the  upper  eye.  and  contains  about  90 
rays  to  the  middle  of  the  base  of  the  caudal.  The  rays  about  the  middle  of  the  tin  are  the 
longest,  their  height  being  a  little  more  than  4,  that  of  the  body.  The  distance  of  the  anal 
tin  from  the  snout  is  contained  3f  times  in  total  length.  The  longest  anal  rays  are  about 
the  middle  of  the  body;  their  length  is  equal  to  that  of  the  longest  in  the  dorsal.  The 
anal  is  connate  with  the  caudal,  and  consists  of  09-75  rays. 

The  length  of  the  median  caudal  rays  is  contained  nearly  seven  times  in  the  total 
length.  The  distance  of  the  ventral  from  the  snout  is  contained  4|  times  in  the  total  length. 
It  is  separated  from  the  anal  by  a.  distance  equal  to  the  long  diameter  of  the  eye.  The  num- 
ber of  ventral  rays  is  four;  tin-  longest  ray  is  3J  times  as  long  as  head. 

Color  grayish  or  brownish,  with  a  submetallic  lustre  upon  the  scales  when  examined 
separately.  Thedenticnlations  of  the  scales  are  dark  anil  prominent,  giving  a  clouded 
general  aspect.  .Some  of  the  smaller  specimens  (from  station  2318)  have  a  few  large  irreg- 
ular brownish  blotches  above  and  a  dark  subcircular  blotch  near  the  root  of  the  tail,  its 
diameter  twice  that  of  the  eye.    Colorless  below. 

Radial  formula:  D.  90;  A.  09-75;   V.  4;   P.  none.     L.  lat,  05. 

The  species  is  described  from  a  specimen  obtained  by  the  Blake  from  station  xxiii,  off 
St.  Kitt's,  West  Indies,  at  a  depth  of  250  far  horns;  with  specimens  obtained  by  the  Albatross 
from  station  2318,  in  24°  25'  45"  N.  lat.,  81°  40'  45"  W.  Ion.,  at  a  depth  of  45  fathoms,  and

The  length  of  the  head  is  contained  5  times  iu  total  length;  the  length  of  the  snout  in 
that  of  the  head  5J  limes,  and  equals  the  diameter  of  the  eye. 

Eyes  small,  very  closely  approximated  in  the  same  vertical  line.  The  nostril  is  tubu- 
lar, placed  midway  between  the  lower  eye  and  the  tip  of  the  snout. 

Mouth  small,  oblique,  curved,  its  posterior  augle  under  the  anterior  margin  of  the 
pupil  of  the  lower  eye,  the  Length  of  its  gape  in  that  of  the  head  4jj  times,  in  greatest  height

The  dorsal  tin  begins  in  the  vertical  through  the  pupils  and  is  composed  of  78  rays; 
its  greatest  height  is  contained  2jj  times  in  that  of  body. 

The  anal  is  separated  from  the  snout  by  a  distance  about  equal  to  the  height  of  the 
body,  and  7]  times  the  length  of  the  snout,  it  has  70  rays;  its  greatest  height  equals  one-

Three  European  species  of  Trigla  were  fouad  by  the  French  explorers  below  100 
fathoms. 

(1.)  Trigla  euculus,  Linn.  (=Triglapini7  Bloch),  taken  in  the  Gulf  of  Gascony  in  306 
meters  (  Travailleur  station  xvn).  It  is  a  well-known  inshore  form,  from  the  British  Islands 
to  the  Mediterranean,  where,  however,  it  is  not  especially  abundant.  There  is  no  satisfac 
tory  evidence  that  it  has  ever  been  found  in  the  western  Atlantic. 

(2.)  Trigla  lyra,  Linn.,  found  iu  the  Gulf  of  Gascony  in  411  fathoms  (Trarailleur  sta 
tion  vin). 

(3.)  Trigla  cavillone,  Lacepede  [=Lepidotrigla  aspera  (C.  &  V.)  Giinther],  taken  off 
Soudan,  in  130-355  meters;  on  the  Banc  d'Arguin,  in  140-175;  off  Morocco,  in   1-0;  off 
Spain,  in  99,  and  near  the  Cape  Verdes,  in  90.     For  notes  on  these  three  species  see   Vail 
hint,  p.  350. 

The  Challenger  took  Trigla  leptacantha,  Giinther,  and  Trigla  spiloptera,  Giinther,  off 
the  Ki  Islands,  in  140  fathoms  (station  192). 

Trigla  hemisticta,  Schlegel,  has  been  found  below  the  hundred  fathom  line  in  the  Bay 
of  Bengal,  about  40  individuals,  many  of  them  females  with  mature  ovaries,  having  been 
taken  at  Investigator  station  No.  00.     (Alcock,  Ann.  and  Mag.  Nat.  Hist.,  1SS9,  n,  207.)

PRIONOTUS  MILITAEIS,  Goor.F.  and  Bean,  n.  s.     (Figures  380,  384.) 

The  type  of  the  description  is  a  specimen  measuring  ll!3  millimeters  with  the  caudal. 
The  length  without  the  caudal,  which  is  the  standard  of  comparison,  is  95  millimeters. 
The  body  is  short  and  stout,  its  greatest  height  (30  millimeters)  nearly  one-third  of  the 
standard  length;  its  greatest  width  at  the  base  of  the  pectorals  (23  millimeters)  is  nearly 
one-fourth  of  the  standard  length.  The  least  height  of  the  tail  (9  millimeters)  is  equal  to 
the  long  diameter  of  the  eye.  The  head  is  short,  the  snout  abruptly  descending  and  with 
two  rather  long  diverging  spinous  processes  at  its  tip.  The  orbits  are  much  elevated,  the 
spi nes  very  large,  and  the  jaws  are  small.  The  greatest  length  of  the  head,  measured 
horizontally  (33  millimeters),  is  about  one-third  of  the  standard  length.  The  distance 
measured  obliquely  from  the  tip  of  the  rostral  spine  to  the  edge  of  the  opercular  flap  (39 
millimeters)  is  two-fifths  of  the  standard  length.  Nearly  all  the  spines  of  the  head  and 
the  exposed  edges  of  the  preorbital,  mandible,  and  opercles  are  minutely  serrate.  The 
diverging  spines  upon  the  snout  are  themselves  armed  along  the  margin  by  numerous 
spinules.  The  length  of  the  eye  (9  millimeters)  equals  the  width  of  the  interorbital  area. 
The  snout  (14  millimeters)  is  more  than  one-third  the  length  of  the  head.  A  strong  spine 
on  the  preopercle,  with  a  secondary  spine  at  its  base.  The  spine  on  the  preopercle  is  as 
long  as  the  snout.  A  stout  spine  on  the  operculum,  another  in  the  humeral  region,  another 
on  the  nape  extending  backward  to  the  base  of  the  fourth  dorsal  spine.  Teeth  in  the  jaws 
and  on  the  vomer  and  palate  very  small,  in  villit'orm  bands.  The  length  of  the  maxilla 
(10  millimeters)  is  a  little  greater  than  that  of  the  eye.  The  length  of  the  mandible  (12 
millimeters)  is  a  little  less  than  that  of  the  snout — it  reaches  about  to  the  vertical  from 
the  front  of  the  eye.  There  is  a  furrow  across  the  nape  immediately  behind  the  eyes. 
Nine  developed  gill  rakers  on  the  anterior  arch,  besides  several  rudiments;  all  of  the  gill 
rakers  very  short.  Pseudobranchise  present,  Branchiostegals  7.  The  distance  of  the 
dorsal  from  the  tip  of  the  snout  (39  millimeters)  is  two-fifths  of  the  standard  length. 
The  first  two  spines  are  very  much  produced;  the  length  of  the  first  (85  millimeters)  is 
almost  equal  to  the  standard  length:  the  length  of  the  second  (87  millimeters)  is  slightly 
greater  than  that  of  the  first.  The  short  spine  (23  millimeters)  is  about  twice  as  long  as 
t  he  mandible.  When  t  lie  dorsal  spines  are  fully  extended  they  reach  nearly  to  the  tip  of  the 
caudal.  The  anterior  margins  of  the  first  three  spines  are  minutely  serrated,  the  serrations 
being  in  several  rows.  The  longest  ray  of  the  soft  dorsal  (17  millimeters)  is  about  one-half 
as  long  as  the  head.  The  length  of  the  middle  caudal  rays  (25  millimeters)  equals  the 
length  of  the  anal  base.  The  caudal  is  slightly  emarginate.  The  length  of  the  pectoral 
(51  millimeters)  is  a  little  more  than  one-half  of  the  standard  length.  The  longest  sepa- 
rate ray  of  the  pectoral  is  about  H  times  as  long  as  the  shortest;  its  length  equal  to  that 
of  the  middle  caudal  rays.  The.  length  of  the  ventral  spine  (14  millimeters)  is  one-half 
the  length  of  the  longest  ventral  ray  (28  millimeters).  The  ventral  when  extended 
leaches  to  the  third  ray  of  the  anal.  The  longest  anal  ray  (10  millimeters)  is  about  one- 
halt  as  long  as  the  head.  The  scales  are  very  rough;  they  are  in  about  7  rows  between  the 
origin  of  the  second  dorsal  and  the  lateral  line,  and  19  rows  below  the  lateral  line.  The 
lateral  line  contains  about  40  tubes,  and  the  number  of  rows  of  scales  counted  obliquely  is 
about  55.

PRIONOTUS  EGRETTA,  Goods  and  Id w.  n.  b.     (Figure  381.) 

The  standard  length,  which  i.s  the  total  length  without  the  caudal,  is  ion  millimeters. 
The  body  is  rather  slender,  rapidly  tapering  posteriorly.  The  greatest  height,  which  is  at 
the  ventrals  (23  millimeters),  is  contained  1A  times  in  the  standard  length.  The  least  height 
of  the  tail  (7  millimeters)  equals  half  the  length  of  the  intermaxillary.  The  head  is  moder- 
ately long,  ils  greatest  length  (40  millimeters)  contained  25j  times  in  the  standard  length. 
The  snout  docs  not-deseend  so  abruptly  as  in  /'.  militarius  and  is  without  projections  from 
the  front.  Its  length  (17  millimeters)  is  half  the  length  of  the  ventral.  The  width  of  the 
interorbital  space  (<i  millimeters)  equals  half  the  long  diameter  of  the  eye  (11'  millimeters). 
The  length  of  the  eye  is  contained  3J  times  in  that  of  the  head.  The  spines  of  the  head  are 
moderately  strong  and  are  without  subsidiary  basal  spines.  The  length  of  the  spine  at  the 
angle  of  the  preopereuluin  is  nearly  equal  to  that  of  the  opercular  spine,  and  is  nearly  half 
the  length  of  the  snout.  The  exposed  edges  of  the  bones  of  the  head  are  minutely  serrated,  but 
the  teeth  at  the  end  of  the  snout  are  slightly  enlarged.  Humeral  spine  small,  nuchal  spines 
not  well  developed.  One  or  two  spines  at  the  front  of  the  supraorbital  and  two  or  three  at  its 
posteiioi  portion.  About  9  developed  gill  rakers  on  the  anterior  arch;  the  longest  of  them 
about  2  millimeters  in  length.  Teeth  in  villiform  bands  in  the  jaws  and  on  the  vomer  and 
palate.  The  vomerine  band  very  narrow.  The  length  of  the  maxilla  (14  millimeters)  nearly 
one-third  the  length  of  the  head.  The  length  of  the  mandible  (17  millimeters)  equals 
the  length  of  the  snout.  The  mandible  reaches  nearly  to  the  vertical  from  the  front  of  the 
eye.  A  very  slight  groove  across  the  nape  immediately  behind  the  eyes  continued  down 
ward  by  an  interspace  between  the  preopercle  and  operele.  The  distance  of  the  dorsal 
from  the  tip  of  the  snout  (39  millimeters)  is  about  equal  to  the  length  of  the  head.  The 
base  of  the  spinous  dorsal  (24  millimeters)  equals  the  length  of  the  head  without  the  snout; 
the  first  spine  is  coarsely  serrated  for  the  first  sixth  of  its  length,  and  is  produced  into  a 
filament,  which  extends  beyond  the  end  of  the  caudal  when  laid  back,  making  the  length 
of  the  first  spine  (117  millimeters)  greater  than  the  standard  length  of  the  fish;  several  of 
the  succeeding  spines  are  also  weakly  seriated  on  their  anterior  margin.  The  length  of 
the  second  spine  (22  millimeters)  nearly  equal  to  that  of  the  base  of  the  fin.  The  last  three 
spines  are  very  small.  The  first  ray  of  the  second  dorsal  is  also  serrated  on  its  anterior 
margin;  the  rays  greatly  increase  in  size  posteriorly  to  the  ninth,  which  is  nearly  one-half  as 
long  as  the  head.  The  base  of  the  second  dorsal  (28  millimeters)  is  twice  as  long  as  the 
maxilla.  The  caudal  is  somewhat  emarginate,  the  length  of  the  middle  rays  (2G  millimeters) 
a  trifle  longer  than  the  base  of  the  spinous  dorsal.  The  anal  origin  is  almost  directly  under 
that  of  the  second  dorsal.  The  length  of  the  spine  (7  millimeters)  is  about  two-thirds  that 
of  the  first  ray.  The  anal  lays  increase  in  length  posteriorly,  the  length  of  the  ninth  (14 
millimeters)  being  one-half  of  the  base  of  the  second  dorsal.  The  length  of  the  pectoral 
(34  millimeters)  is  less  than  the  length  of  the  head;  the  tin  when  extended  reaches  to  the 
vertical  from  the  fourth  ray  of  the  second  dorsal.  The  longest  separate  ray  of  the  pectoral 
•(28  millimeters)  is  as  long  as  the  base  of  the  second  dorsal.  The  shortest  separate  ray  (20 
millimeters)  is  one  half  the  length  of  the  head.  Ventral  when  extended  reaches  to  the 
origin  of  the  anal.  The  scales  arc  very  small,  about  9  rows  between  the  origin  of  the  sec- 
ond dorsal  and  the  lateral  line,  and  about  32  rows  between  the  lateral  line  and  the  vent. 
About  60  tubes  in  the  lateral  line;  nearly  100  oblique  TOWS  can  be  counted  between  the  head 
and  the  caudal  fin.

Prionotus  Stearnsii,  Jordan  ami   Swain,  Proc.   1'.   S.   Nat.   Mus.,   1884  (vni.  541. 

A  Prionotus  allied  to  Prionotus  evolans,  having  head  2§  in  length  (3J  including  caudal); 
depth.  4  (5);  D.  vm-12;  A.  12.  Scales,  (transverse  series),  77;  pores  in  lateral  line  about 
4$.    Length,  3§  inches. 

Body  not  very  slender;  narrowed  but  compressed  above,  the  width  of  the  nape  between 
the  occipital  spines  being  about  one  fifth  the  head.  Head  depressed  and  long,  its  upper 
profile  being  a  little  concave  before  eye.  thence  slightly  convex  or  almost  straight  to  front 
of  dorsal.  Snout  2J  in  head,  not  very  broad,  rather  more  than  usually  rounded  anteriorly 
anil  scarcely  emarginate  at  tip.  Edges  of  snout  without  spine  and  without  distinct  seme, 
the  margin  merely  granular.  Surfaces  of  bones  of  head  comparatively  smooth,  but  rough- 
ened with  small  granules,  which  are  arranged  in  radiating  striae,  much  as  in  P.  evolans,  but 
more  regularly  than  in  that  species. 

Mouth  rather  wide,  the  maxillary  reaching  to  opposite  front  of  the  eye,  the  mandible 
about  to  center  of  eye ;  maxillary  two  in  head.     Bands  of  palatine  teeth  narrow. 

K,\  e  small,  its  diameter  (in  young  specimen  |  4§  in  head.  A  very  small  cirrus  formed  of 
two  or  three  thickish  filaments  from  a  common  base  on  upper  part  of  eye;  its  length  little 
more  than  half  the  pupil.  Interorbital  area  of  moderate  width,  rather  deeply  concave,  its 
least  width  Oi  in  head.  Orbital  rim  not  at  all  elevated,  its  bones  with  entire  or  granulated 
edges.  No  trace  of  spine  or  groove  behind  eye.  <  Occipital  spines  very  weak,  the  outer  pair 
inconspicuous,  not  reaching  nearly  to  front  of  dorsal,  the  inner  pair  altogether  wanting,  no 
trace  of  them  being  seen.  No  spines,  ridges,  or  evident  roughness  on  temporal  region. 
Preopercle  with  a  single  small  spine,  without  smaller  one  at  its  base.  Lower  opercular 
spine  small;  upper  opercular  spine  reduced  to  a  blunt  point.  Humeral  spine  inconspicu- 
ous, not  extending  beyond  opercular  spine.  The  head  is  thus  much  less  completely  armed 
than  in  any  other  of  our  species  of  Prionotus,  the  only  spinous  projections  present  being 
the  occipital,  humeral,  opercular  and  preopercular  spines,  four  pairs.  These  spines  may 
perhaps  become  more  prominent  with  age.     Membranaceous  flap  of  opercle  scaly.

head.     Yeutrals,  1±-  in  head. 

Color,  in  spirits,  brown,  paler  below;   scales  everywhere,  with  dark  punctulations,  these 
formiug  a  darker  shade  on  the  lateral  line  near  the  middle  of  the  body;  the  head  plain 
brown.     Spinous  dorsal  dusky  posteriorly.     Soft  dorsal  with  two  dusky  longitudinal  shades. 
Caudal  blackish  at  tip.    Anal  witli  a  black  stripe  toward  the  margin.    Pectorals  black,  the' 
detached  rays  and  ventral  fins  plain  whitish. 

The  type  of  this  species  (No.  36943,  U.  S.  N.  M.),  3§  inches  long,  in  good  condition,  was 
taken  from  the  stomach  of  a  Bed  Snapper.  Lutjanus  Blackfordii,  at  Pensacola.

DISCUSSION    OF    SPECIES    AND    THEIR    DISTRIBUTION.  407 

The  Albatross  obtained  specimens  from  the  following  localities:  Station  2405,  in  28° 
l.v  N.  lai.,  85  02'  W.  Ion.,  at  a  depth  of30  fathoms;  station  2400,  in  28  U'  N.  hit.,  86°  07'

PRIONOTUS  AI, ATI's,  GOODB  and  Bean.     (Figure  382.) 
Prionotua  alattis,  Goode  and  Ukan,  Boll.  Mas.  Coinji.  Zoiil.,  x,  1883,  210. 

A  Prionof/us  with  the  body  normal  in  form,  rather  robust;  its  greatest  height  « -< 1 1 1 : 1 1 

to  one  -fourth  its  length  without  caudal,  and  nearly  equal  to  one- fifth  of  the  total  length; 
its  greatest  width  one-fifth  of  its  greatest  length  without  caudal;  the  least  height  of  tail 
contained  12  times,  or  nearly  so,  in  the  standard  body  length,  and  ;J  times  in  the  height  of 
the  body. 

Scales  small  and  much  pectinate,  there  being  in  the  lateral  line  about  one  hundred 
vertical  rows  of  scales,  about  51)  of  which  are  tube  bearing  and  specialized.  The  number 
of  rows,  counting  diagonally  around  the  body  from  the  origin  of  the  anal,  is  L'l  below 
and  7  above  the  lateral  line.  The  length  of  the  head  to  the  tip  of  the  preopercular 
spine  is  contained  -i  times  iu  the  standard  body  length,  and  very  little  more  than  .'» 
times  in  the  total  length.  The  width  of  the  head  is  equal  to  its  height.  The  upper  limb  of 
the  orbit  encroaches  upon  the  upper  profile  of  the  head,  and  the  center  of  the  pupil  is  equi- 
distant from  the  tii>  of  the  snout  and  the  tip  of  the  prolonged  preopercular  spine.  The 
length  of  the  snout  measured  obliquely  from  the  anterior  margin  of  the  orbit,  is  equal  to 
that  of  the  postorbital  portion  of  the  head  to  the  end  of  the  opercular  spine.  At  the  lower 
angle  of  the  preoperculum  is  a  robust  spine,  curving  slightly  upwards,  the  length  of  which 
is  equal  to  that  of  the  first  dorsal  ray.  This  spine  is  serrated  upon  its  outer  edge,  and  has 
a  small  spine  at  its  base,  which  is  also  serrated.  The  tip  of  the  spine  extends  to  the  per- 
pendicular from  the  center  of  the  interspace  between  the  third  and  fourth  dorsal  spines; 
while  that  of  the  humeral  spine  extends  to  the  perpendicular  from  the  interspace  between 
the  fourth  and  fifth,  and  that  of  the  opercular  to  the  perpendicular  from  the  center  of  the 
base  of  the  third.  There  is  a  strong  scapular  spine,  which  extends  back  to  the  posterior 
edge  of  the  second  dorsal  spine. 

The  leng  th  of  the  upper  jaw  is  equal  to  one-third  that  of  the  head.  The  palatine  teeth 
are  in  short  feeble  bands,  hardly  perceptible  even  with  a  strong  magnifying  glass.  Gill 
rakers,  (i  iu  number,  besides  several  rudimentary  ones,  5  being  below  the  angle,  and  the 
longest  equal  in  length  to  one  third  the  diameter  of  the  eye. 

The  first  dorsal  fin  is  inserted  above  the  tip  of  the  upper  opercular  spine,  and  at  a  dis- 
tance from  the  snout  equal  to  twice  the  length  of  the  fourth  dorsal  spine.  The  height  of 
the  first  dorsal  spine,  which  is  equal  to  that  of  the  third,  and  slightly  less  than  that  of  the 
second,  equals  half  the  length  of  the  head.  Its  anterior  margin  is  strongly  serrated,  while 
those  of  the  second  and  thinl  spines  are  less  markedly  so.  The  length  of  base  of  first  dor- 
sal equals  the  greatest  height  of  body;  the  distance  between  its  insertion  and  that  of  the 
second  dorsal  fin  is  equal  to  the  length  of  the  longest  and  superior  detached  pectoral  ray. 
The  second  dorsal  fin  is  inserted  in  the  perpendicular  over  the  interspace  between  the  sec- 
ond and  third  anal  rays;  the  length  of  its  longest  ray  equals  twice  the  least  height  of  tail, 
and  the  length  of  its  base  equals  the  greatest  length  of  the  ventral  rays.  Its  first  ray  is 
conspicuously  serrated  on  its  anterior  edge. 

The  insertion  of  the  anal  tin  is  in  the  perpendicular  below  the  end  of  the  first  dorsal 
fin:  the  length  of  its  longest  ray  is  equal  to  half  that  of  the  middle  caudal  rays. 

The  caudal  is  truncated,  very  slightly  emarginate. 

The  pectoral  is  very  peculiar  in  structure,  its  longest  ray,  the  ninth,  reaching  to  the 
base  of  the  caudal  rays,  and  equal  in  length  to  four  times  that  of  the  fourth  dorsal  spine. 
The  tenth  ray  is  a  little  bit  shorter,  extending  nearly  to  the  end  of  the  soft  dorsal.  The 
eleventh,  twelfth,  and  thirteenth  rays  are  graduated,  decreasing  in  regular  proportion,  the 
thirteenth  being  less  than  one  fourth  as  long  as  the  tenth.  The  eighth  is  about  midway 
between  the  tenth  and  eleventh;  the  first  is  slightly  longer  than  the  twelfth  and  those  inter-

mediate  between  the  first  and  the  eighth  are  graduated  in  length,  so  as  to  form  a  rounded 
outline  for  the  anterior,  or  upper,  portion  of  the  fin.  The  pectoral  appendages  are  slender, 
the  third  being  slightly  greater  in  length  than  the  thirteenth  ray,  being  two-thirds  as  long 
as  the  first,  while  the  second  is  intermediate  between  the  other  two. 

The  ventral  is  inserted  directly  under  the  base  of  the  pectoral  appendages;  its  first 
spine  about  equal  in  length  to  the  preopercular  spine  from  the  base  of  the  supplemental 
spines:  its  longest,  the  third  and  fourth,  exactly  equal  in  length  to  the  base  of  the  second 
dm  sal. 

Radial  formula:  D.  X,  12;  A.  11  ;  C.  3—7+5—4;  P.  13+3;  V.  l,  5. 

L.  lat.  about  100.     Tube-bearing  scales,  about  50. 

Color,  brownish  above,  with  about  four  indistinct  transverse  band  like  blotches,  one  of 
which  is  on  the  base  of  the  caudal:  whitish  beneath.  Vertical  fins  uniform,  the  tips  of 
the  caudal  rays  blackish,  with  two  indistinct  cloud  like  bands  in  advance  of  the  terminal 
bands  thus  formed.  A  black  blotch,  with  whitish  interior  margin  on  the  membrane  be- 
tween the  fourth  and  fifth  dorsal  spines;  a  very  inconspicuous  blackish  spot  on  the  mem- 
brane between  the  fifth  and  sixth;  others  still  less  conspicuous  on  the  succeeding  inter- 
spaces.    The  pectoral  blotched  and  clouded  with  blackish  brown  and  white. 

A  single  specimen  of  this  species  of  Priotwtus  was  obtained  off  Charleston,  S.  0.,  in 
the  same  haul  with  the  pleuronectoid  described  above  under  the  name  Notosema  dilecta.

PRIONOTUS  BEANII,  Goode,  n.  s.     (Figure  383.) 

A  species  of  Prionotus  having  the  greatest  height  of  the  body  (29  millimeters)  nearly 
one-fourth  of  the  standard  length.  Its  greatest  width  (27  millimeters)  is  slightly  less 
than  its  height.  The  least  height  of  the  tail  (8  millimeters)  is  nearly  one-fifth  of  the 
length  of  the  head,  and  is  equal  to  the  short  diameter  of  the  eye,  The  head  is  moderately 
lung,  its  length  (3!)  millimeters)  being  one-third  of  the  standard  length.  The  width  of  the 
interorbital  space  on  the  bone  ((!  millimeters)  is  about  one-third  the  length  of  the  snout. 
There  is  a  furrow  behind  the  eyes  which  is  interrupted  on  the  nape.  The  snout  is  produced 
into  two  short  obtuse  serrated  points  flanked  behind  011  each  side  by  a  short  but  stout  com-

pressed  spine;  behind  this  on  the  snout  another  short  spine.  A  short  spine  on  the  cheek 
bone.  Anterior  nostril  in  a  tube  which  is  produced  posteriorly  into  ;i  little  flap;  posterior 
nostril  in  a  large  shorter  tnbe.  The  preopercular  spine,  also,  has  a  short  spine  ;it  its  base. 
Preocular  and  supraocular  spines  present.  A  pair  of  postocalar  spines  on  each  side,  one  in 
front  of  the  other.  A  pair  of  blunt  spines  on  the  occipul  and  another  pair  on  the  nape. 
Length  of  opercular  spine,  measured  back  to  the  edge  of  the  preopercie,  equals  the  length 
of  the  postorbitaJ  part  of  the  head.     Humeral  spine  well  developed,  its  length  nearly  equal 

to  that  of  the  preocular.      The  maxilla  does  not  reach  to  the  front  of  the  eye,  its  length  (11 

millimeters)  being  equal  to  the  postorbital  part  of  the  head.  The  inaudible  reaches  about  to 
the  vertical  from  the  front  of  the  eye:  its  length  (is  millimeters)  nearly  one-half  the  length 
of  the  head.  Teeth  in  narrow  villiform  hands  in  the  jaws  and  on  the  vomer  and  palate. 
Bight  developed  gill  rakers  on  the  anterior  arch.  The  longest  about  one-third  as  long  as  the 
eye;  live  rudiments  below  and  two  above  the  developed  rakers  of  the  anterior  arch;  these 
are  mere  tubercles  scarcely  raised  above  the  general  surface.  The  length  of  the  eye  (it  milli- 
meters) is  one-half  the  length  of  the  snout  and  nearly  one-fourth  the  length  of  the  head. 
The  snout  (is  millimeters)  is  equal  to  twice  the  length  of  the  eye  and  equals  the  length  of 
the  mandible.  The  distance  of  the  dorsal  from  the  tip  of  the  snout  (41'  millimeters)  is  a  little 
greater  than  the  length  of  the  head.  The  length  of  the  base  of  the  spinous  dorsal  (26 
millimeters)  nearly  three  limes  the  length  ot  the  eye.  The  first  spine  is  serrated  on  its 
anterior  margin  for  the  greater  portion  of  its  height;  it  is  nearly  as  long  as  the  second,  its 
length  (Hi  millimeters)  is  two  tilths  the  length  of  the  head;  the  third  spine  is  the  longest,  its 
length  (20  millimeters)  is  one  half  the  length  of  the  head.  The  last  two  spines  are  very 
small.  The  third  spine,  also,  is  serrated  along  its  anterior  margin  for  the  greater  portion  of 
its  height.  There  is  a  very  slight  interspace  between  the  t  wo  dorsals.  The  length  of  the 
fast  ray  of  the  soft  dorsal  (16  millimeters)  equals  that  of  the  second  spine  of  the  dorsal;  the 
length  of  the  last  ray  (13  millimeters)  equals  one  half  of  the  length  of  the  spinous  dorsal 
base,  'flic  length  of  the  middle  caudal  rays  (27  millimeters)  equals  three  times  the  length  of 
the  eye.  The  caudal  is  .■-lightly  emarginate.  The  origin  of  the  anal  is  immediately  under 
the  origin  of  the  soft  dorsal.  The  length  of  the  anal  base  (.">2  millimeters)  is  one-half  the 
distance  of  the  anal  from  the  tip  of  the  snout.  The  spine  is  only  about  two-thirds  as  long 
as  the  first  ray;  its  length  (7  millimeters)  is  one-hall'  tin'  length  of  the  maxilla.  The  length 
of  the  longest  anal  ray  (12  millimeters)  is  one-half  the  length  of  the  spinous  dorsal  base. 
The  ventral  extends  to  the  origin  of  the  anal;  its  length  (33  millimeters)  equal  to  the  anal 
base.  The  pectoral  when  extended  reaches  to  the  line  connecting  the  tilth  ray  of  the  dorsal 
with  the  sixth  ray  of  the  anal.  This  tin  is  emarginate  behind;  its  longest  ray  is  slightly 
longer  than  the  head  and  more  than  twice  as  long  as  the  longest  dorsal  spine. 

Radial  formula:  D.  x,  12;  A.  i.  1<»;  1'.  13  +  3;  V.  r,5. 

The  type  of  the  description  is  a  specimen  112  millimeters  long  to  base  of  caudal.  Its 
catalogue  number  is  39318,  from  station  2120,  steamer  A Ibatross,  N.  lat.,  11°  07'  W.  Ion., 
62°  14'  30",  from  7.;  fathoms,  off  Trinidad. 

Seven  rows  of  scales  between  the  lateral  line  and  origin  of  the  second  dorsal:  lit  rows 
between  lateral  line  and  origin  of  anal;  ■">(>  pores  in  the  lateral  line,  and  about  93  oblique  rows 
of  scales  can  be  counted.     .Scales  on  the  breast  conspicuously  smaller  than  the  others. 

Colors  of  the  alcoholic  specimen,  light  yellowish  brown  above,  lighter  below.    The  spi- 
nous dorsal  has  a  black  blotch  between  the  fourth   and  fifth  spines,  its  length  about  two 
thirds   that   of   the   eye.       The   membrane    connecting    the   spines  of  the  dorsal  with  faint 
dusky  shades  in  several  places.     Membrane  connecting  the  last  three  or  four  rays  of  the 
second  dorsal  slightly  dusky.      The  pectoral   with  two  broad  dark  areas,  separated  and 

surrounded  by  lighter.     The  dark  markings  on  the  pectoral  do  not  take  the  for f  bands. 

and  have  their  greatest  length  nearly  parallel  with  the  axis  of  the  fish.

xxii,  64. 

The  greatest  width  of  the  body  (20)  is  equal  to  its  greatest  height  (19..r>)  being  one- fifth 
of  its  total  length  without  caudal.  The  general  armature  of  the  body  is  much  like  that 
described  by  Giinther  under  Peristethus  brevirostre?  The  number  of  plates  between  the 
yill  openings  and  the  base  of  the  tail  is  from  27  to  29.  There  are  1  series  of  spiny  plates 
on  each  side,  the  spines  of  the  abdominal  series  becoming  very  weak  and  obsolete  towards 
the  tip  of  the  tail. 

The  length  of  the  head  (40.15)  is  two-fifths  of  the  total  length  without  caudal.  The 
length  of  the  preorbital  processes  (7)  is  contained  about  3J  times  in  the  distance  from  their 
extremities  to  the  anterior  margin  of  the  orbit.  The  interorbital  space  is  deeply  concave; 
its  width  (6.75)  contained  between  t>  and  7  times  in  the  length  of  the  head.  Protuberance  on 
the  forehead  very  slight.  The  length  of  the  snout  (22.5)  is  more  than  half  that  of  the  head 
(in  young  less).  The  diameter  of  the  eye  (65)  is  contained  between  <>  aud  7  times  in  the 
length  of  the  head.  There  is  one  pair  of  spines  upon  the  upper  surface  of  the  snout  behind 
the  base  of  the  preorbital  processes,  and  another  larger  pair  upon  the  preorbital  processes, 
one  upon  each.  The  ridge  of  the  preoperculum  terminates  in  a  depressed  short,  sharp- 
pointed  spine.  The  number  of  small  tentacles  upon  either  side  of  the  lower  jaw  is  about 
10,  the  smallest  nearest  to  the  symphysis.  The  long  tentacles  at  the  angles  of  the  mouth 
are  fringed,  and  extend  to  the  base  of  the  pectorals.  In  other  respects  Giinther's  descrip- 
tion of  1'.  brevirostre  is  ample  for  this  species.

472  DEEP-SEA   FISHES   OF    THE   ATLANTIC    BASIN. 

PERISTEDION  LONGISPATHA,  Goode  and  Bean.     (Figure  386.) 
Perisledium  longispatha,  Goode  and  Bean,  Ball.  Mas.  Comp.  Zoiil.,  xn.  No.  5,  166. 

Body  high  anteriorly,  its  greatest  height  (39  millimeters)  contained  4J  times  in  total 
length.  The  length  of  the  head,  without  prolongations,  is  contained  2A  times  in  the  total 
length ;  with  prolongations,  2  times.  The  crown  of  the  head  is  flat,  separated  from  the 
nuchal  plate  by  a  deep  furrow,  which  is  convex  forward.  The  interorbital  space  is  deeply 
concave,  the  supraorbital  margins  being  swollen;  its  width  (10  millimeters)  equal  to  the 
long  diameter  of  the  orbit.  No  protuberance  on  The  forehead,  which  is  much  depressed,  its 
outline  descending  abruptly  and  rapidly  in  front  of  the  eyes.  A  ridge,  but  no  spine, 
beneath  the  eye.  The  length  of  the  snout  (49  millimeters),  including  the  preorbital  exten- 
sion, is  more  than  half  the  length  of  the  head;  the  preorbital  extension  equals  about  half 
the  length  of  the  snout.  The  processes  are  flat,  rounded  anteriorly,  and  covered  with 
minute  granulations;  they  diverge  considerably,  the  distance  of  the  tips  apart  (3G  millime- 
ters), being  nearly  twice  that  at  their  bases  (19  millimeters).  A  ridge  arises  at  the  base  of 
the  preorbital  process  and  extends  to  the  angle  of  the  preoperculum,  and  its  width  at  the 
angle  (8  millimeters)  is  contained  twice  in  the  diameter  of  the  orbit.  A  narrow  inconspicu- 
ous and  interrupted  ridge  below.  A  ridge  on  the  operculum,  ending  in  a  sharp  spine  at 
the  angle;  its  length  is  equal  to  the  diameter  of  the  eye. 

The  jaws  arc  feeble,  toothless;  the  lower  jaw  with  2  long,  much  fringed  barbels  and 
14  shorter  ones.  The  length  of  the  long  barbels  (32  millimeters),  twice  the  diameter  of  the 
eye. 

The  maxilla  does  not  quite  reach  the  vertical  through  the  anterior  margin  of  the  eye. 
The  diameter  of  the  eye  (16  millimeters)  is  contained  4  times  in  the  length  of  the  head

PERISTEDION  GRACILE,  Goode  ami  Bean,  n.  8.  (Figure  387). 

Body  very  slender;  its  greatest  height  (18  millimeters)  is  nearly  one-sixth  of  its  length. 
The  length  of  the  head  to  the  tip  of  the  prolongated  rostral  spine  is  48  millimeters;  without 
the  prolongations  its  Iengthis36  millimeters  or  twice  the  greatest  heightof  the  body.  The 
interorbital  space  is  deeply  concave.  Theinterorbital  width  (10  millimeters)  equals  one  half 
the  length  ofthe  snout  including  the  rostral  spine.  The  forehead  descends  gently  towards 
the  snout  and  the  supraorbital  crests  are  very  little  elevated.  The  rostral  spine  on  each 
side  is  continued  backward  by  a  slight  bony  ridge  ending  in  a  blunt  spine  at  the  angle  of 
the  preoperculum.  The  opercular  spine  is  small,  the  length  of  the  operculum  with  the 
spine  being  about  equal  to  the  length  of  the  eye.  The  length  ofthe  snout  with  preorbital 
extension  (29  mil  li  meters)  is  a  little  more  than  one-fourth  of  the  standard  length ;  the  length 
of  the  spine  alone  (13  millimeters)  is  nearly  equal  to  the  length  of  the  mandible.  The  jaws 
are  feeble  and  toothless.  The  length  ofthe  maxilla  (12  millimeters)  is  one  fourth  the  length 
ofthe  head.  The  length  of  the  mandible  (15  millimeters)  is  one-half  the  length  of  the 
SnOUl  with  the  preorbital  extension.      The  mandible  has  two  groups  Of  barbels,  one  on  each 

side  of  its  lower  edge.  The  length  of  the  longest  barbel  (0  millimeters)  equals  that  of  the 
eye.  The  barbels  are  subdivided  into  several  fringes;  the  number  of  barbels  on  each  side 
ofthe  mandible  may  be  divided  up  into  8  or  9  clusters.  The  mandible  extends  to  the  ver- 
tical through  the  front  ofthe  eye.  Twenty-  six  gill-raker  s  on  the  first  arch,  the  longest  one 
half  as  Ion-'  as  the  eye.  The  longitudinal  diameter  of  the  eye  (9  millimeters)  is  nearly 
equal  to  the  width  ofthe  interorbital  space.  Greatest  width  of  the  head  over  the  prcorbi 
tal  ridge  (15  millimeters)  is  one  half  the  length  of  the  snout  including  the  preorbital  ex  ten 
sion.  The  spinous  dorsal  originates  directly  above  the  end  of  the  opercular  flap;  the  first 
spine  is  slightly  the  longest,  its  length  (15  millimeters)  equals  the  length  ofthe  snout  and 
its  projecting  spine;  it  also  equals  the  short  diameter  of  the  eye.  The  longest  ray  of  the 
second  dorsal  |  1  1  millimeters)  is  nearly  one-fourth  the  length  of  t  he  head.  The  least  height 
of  the  tail  (3  in il I i met ets)  is  one  third  the  length  of  the  eye.  The  anal  origin  is  under  the 
second  ray  of  the  soft  dorsal ;  the  fin  extends  as  far  back  as  the  dorsal,  the  length  of  its 
base  (II  millimeters)  being  I  times  the  width  of  the  interorbital  area,  the  lays 
about   as   long  as  those  of  the   second   dorsal.      The   length   of  the   middle  caudal  rays  (12 

millimeters)  is  four-thirds  the  length  of  the  eye,  the  tin  being  emarginate.  The  ventral 
base  is  under  the  pectoral  base,  the  fin  reaching  to  the  vent,  its  length  (18  millimeters)  twice

••The  ribbon  fishes."  says  Giinther,  "  are  true  deep  sea  fishes,  met  with  in  all  parts  of 
the  oceans,  generally  found  when  floating  dead  on  the  surface,  or  thrown  ashore  by  the 
waves.  Their  bodj  is  like  a  band,  specimens  of  from  15  to  20  feet  long  being  from  L0  to 
12  inches  deep  and  about  an  inch  or  fwo  broad  at  their  thickest  part.  The  esc  is  large 
and  lateral;  the  mouth  small,  armed  with  very  feeble  teeth;  the  head  deep  and  short.  A 
high  dorsal  tin  runs  along  the  whole  length  of  the  back,  and  is  supported  In  extremely 
numerous  rays;  its  foremost  portion,  on  the  head,  is  detached  from  the  rest  of  the  tin,  ami 
composed  of  \  erj  elongate  flexible  spines.  The  anal  tin  is  absent.  The  caudal  fin  (if  pre 
Served,  which  is  rarely  the  case,  in  adult  specimens)  has  an  extra  axial  position,  being 
directed  upwards  like  a  fan.  The  ventrals  are  thoracic,  either  composed  of  several  rays  or 
reduced  to  a  Bingle  long  filament.     The  coloration  is  generally  silvery,  w  ith  rosy  tins. 

■•When  these  lishes  reach  the  surface  of  the  water  the  expansion  of  the  gases  within 
their  bodies  has  so  loosened  all  the  parts  of  their  muscular  and  bon\  system  that  they  can 
be  lilted  out  of  the  water  with  dillicully  only,  and  nearly  always  portions  of  the  body  and 
tins  are  broken  ami  lost.  The  bones  contain  very  little  bony  matter,  are  verj  porous,  thin, 
and  buhl.  At  what  depth  ribbon  lishes  live  is  not  known:  probably  the  depths  vary  for 
different  species;  but  although  none  have  been  yet  obtained  by  means  of  the  deep-sea 
dredge,  thej  must  be  abundant  at  the  bottom  of  all  oceans,  as  dead  lishes  or  fragments  of 
them  an-  frequently  obtained.  Some  writers  have  supposed  from  the  greal  length  and 
narrow    shape  of  these  lishes  that  they  have  been  mistaken  for   'sea  serpents,'  but  as  these

Ta^niosomes  with  the  body  moderately  elongated  and  very  compressed,  the  head  short, 
the  opercular  apparatus  abbreviated  (the  operculum  extended  downwards,  the  suboper- 
culum  below  it,  and  the  interoperculum  contracted  backwards  and  bounded  behind  by  the 
operculum  ami  suboperculum),  ventrals  pauciradiate  in  young,  atrophied  or  lost  in  adult, 
the  cranium  with  a  myodome  ami  dichost,  the  supraoecipital  continued  behind  into  a  promi- 
nence, the  epiotics  confined  to  the  sides  and  hack  of  the  cranium,  and  without  ribs. 

The  ribbon-fishes  are  well  known  in  the  Eastern  Atlantic  and  the  Mediterranean,  and 
have  even  been  found  as  far  west  as  Madeira.  Traehypterus  has  never  been  found  in  the 
Western  Atlantic.  Some  few  representatives  have  been  found  on  the  west  coast  of  South 
America,  and  one  or  two  examples  have  been  taken  in  New  Zealand.  They  are  generally 
admitted  to  be  true  deep-sea  tishes.  which  live  at  very  great  depths,  and  are  only  found 
when  floating  dead  on  the  surface  or  washed  ashore  b\  the  waves.  Almost  nothing  is  known 
of  their  habits  except  through  Nilsson's  observations  in  the  far  north.  This  naturalist,  as 
well  as  Olafsen,  appears  to  have  had  the  opportunity  of  observing  them  in  life.  They  say 
that  they  approach  the  shore  at  flood  tide  on  sandy  shelving  bottoms,  and  are  often  left  by 
the  retreating  waves.  Nilsson's  opinion  is  that  their  habits  resemble  those  of  the  "flat- 
lishes."  and  that  they  move  with  one  side  turned  obliquely  upward,  the  other  toward  the 
ground:  and  he  says  that  they  have  been  seen  on  the  bottom  in  2  <>r  .".  fathoms  of  water, 
where  the  fishermen  hook  them  up  with  the  implements  employed  to  raise  dead  seals,  and 
that  they  are  slow  swimmers.  This  is  not  necessarily  the  ease,  however,  for  the  removal 
of  pressure  and  the  rough  treatment  .by  which  they  were  probably  washed  upon  the  shore 
would  be  demoralizing,  to  say  the  least.  Trichiurus  lepturus,a  tish  very  similar  in  form. 
is  a  very  strong,  swift  swimmer. 

Whether  or  not  the  habits  of  Traehypterus  arcticus,  on  which  these  observations  were 
made,  are  a  safe  guide  in  regard  to  the  other  forms  is  a  matter  of  some  doubt,  hut  it  is 
certain  that  they  live  far  from  the  surface,  except  near  the  Arctic  Circle,  and  that  they 
only  come  ashore  accidentally.  They  have  never  been  taken  by  the  deep  sea  dredge  or 
trawl  net,  and  indeed  perfect  specimens  are  very  rare,  the  bodies  being  very  soft  and  brit- 
tle, the  bones  and  tin  rays  exceedingly  fragile. 

A  considerable  number  of  species  have  been  described,  but  these  are.  in  most  instances, 
based  upon  one  or  two  specimens.  It  is  probable  that  future  studies  may  lie  as  fruitful  as 
that  of  Emery,  who.  by  means  of  a  series  of  23  specimens,  succeeded  in  uniting  at  least 
three  of  the  Mediterranean  species,  which  for  half  a  century  or  mote  had  been  regarded  as 
distinct.  As  has  been  remarked,  not  a  single  individual  of  Traehypterus  has  ever  been 
found  in  the  Western  Atlantic,  although  the  common  species  of  the  Eastern  Atlantic,  T.

secured  along  the  coast  of  Northern  Europe  after  almost  every  severe  gale.  We  have 
deemed  it  desirable  to  include  in  this  paper  partial  diagnoses  and  references  to  the  litera- 
ture concerning  each  of  the  species  at  present  recognized  in  the  Atlantic  Basin,  in  order 
that  American  naturalists  may  have  at  hand  a  convenient  means  of  identifying  material 
which  is  almost  certain,  sooner  or  later,  to  fall  into  their  hands. 

We  desire  to  quote  the  recommendation  of  Dr.  Giinther,  and  to  strongly  urge  upon 
anyone  who  may  be  so  fortunate  as  to  secure  one  of  these  fishes  that  no  attempt  should

Trachypterids  having  the  body  elongate,  compressed,  riband-shaped,  the  dorsal  fin 
extending  the  entire  length  of  the  hack.  Anal  absent;  each  ventral  well  developed,  if  pres- 
ent, but  sometimes  absent.  Caudal  present  and  placed  for  the  most  part  above  the  longi- 
tudinal axis  of  the  body.     No  air  bladder.     Pyloric  appendages  numerous. 

'I'lie  ventrals  appear  to  be  absent  in  some  individuals,  but  Day  calls  attention  to  the 
tact  that  most  of  the  specimens  of  T.  arcticus  taken  along  the  coast  of  Great  Britain  have 
had  no  ventrals.  In  the  very  young,  as  has  been  shown  by  Emery,  the  tin  rays  commence 
to  grow  when  it  is  about  <»  millimeters  long,  and  continue  to  lengthen  until  it  is  about  24 
millimeters  long,  after  which  a  partial  shortening  takes  place.  The  ventrals  are  very  elon- 
gate in  the  young,  and  the  caudal  rays  much  longer  than  in  the  grown  fish. 

Young  individuals  (from  li  to  4  inches)  are  not  rarely  met  with  near  the  surface;  they 
possess  the  most  extraordinary  development  of  fin  rays  observed  in  the  whole  class  of 
lishes.  some  of  them  being  several  times  larger  than  the  body,  and  provided  with  lappet- 
like dilatations.  There  is  no  doubt  that  fishes  witli  such  delicate  appendages  are  bred  and 
live  in  depths  where  the  water  is  absolutely  quiet,  as  a  sojourn  in  the  disturbed  water  of 
the  surface  would  deprive  them  at  once  of  organs  which  must  be  of  some  utility  for  their 
preservation.

A  Traehypterus  having  the  lower  line  of  the  body  straight;  dorsal  rays  1.17-1 70,  these 
rays  being  rough;  the  lateral  line  spinous;  and  the  height  of  the  body  contained  from  4  to 
10  times  in  the  total  length  of  the  fish  (excluding  the  caudal). 

Radial  formula:  D.  4-8+120-170;  P.  10. 

Color,  silvery  white,  with  a  few  round,  black  spots  or  blotches. 

Three  species,  for  a  long  time  considered  distinct  by  European  ichthyologists,  and 
recognized  by  them  under  the  names  of  T.  spinolce,  T.  taenia  and  T.  iris,  have  been  shown 
by  Emery  to  be  identical,  being  successive  stages  of  one  and  the  same  species.  In  a  very 
important  paper  published  by  him  in  the  "Acts"  of  the  Academy  of  Lincei,  Rome  (in, 
1870, 390-395,  tigs.  1-0),  and  in  the  "Mittheilungen  aus  der  Zoologischen  Station  zu  Neapel" 
(1879,  1581)  he  has  given  full  particulars  of  his  examinations  of  23  specimens. 

This  species  is  known  only  from  the  Mediterranean.  The  largest  individuals  under  the 
name  of  Traehypterus  iris  have  been  recorded  from  Nice,  Banyul,  Sicily,  Corsica,  Leghorn, 
and  Elba.  The  specimen  discussed  by  Moreau  was  1.5  meters  in  length.  A  smaller  size, 
described  as  T.  spinolw,  has  been  identified  from  Nice,  Cctte,  Elba,  Naples,  and  Sicily.  The 
specimen  obtained  by  Moreau  from  Cette  was  0.95  meter  long.  A  smaller  form,  as  identi- 
fied by  Moreau  under  the  name  of  T.  fake  (T.  tania),  has  been  obtained  from  Nice,  (Jette, 
Messina,  and  Algiers.     Moreau's  specimen  was  0.52  meter  in  length. 

Among  the  common  names  are  Pesee  bannera  (Naples),  Flamba  (Cette),  Squaglia  sole 
(Naples).    Rondeletius  and  Gesner  called  it  Falx  Venetorum — the  Venetian  blade. 

TRACHYPTERUS  GRYPHURUS,  Lowe. 
Traehypterus  grypkurut,  Lowe,  Proc.  Zool.  Soc,  1850,  248. — GOnther,  Cat.  Fish.  Brit.  Mus.,  in,  301. 

Intermediate  between  T.  taenia  and  T.  iris,  approaching  perhaps  nearest  to  the  latter, 
but  differing  in  its  deeper  shape,  its  depth  being  two-elevenths  of  the  total  length,  and  in  the 
more  backward  position  of  the  third  dark  side  spot.  The  ventral  tins  arc  short,  only  equal- 
in:'  one-twelfth  of  the  body  without  the  caudal  tin,  and  the  first  four  produced  rays  of  the 
first  dorsal  are  equal  in  length  to  the  ventral  tins.  The  lateral  line  ends  as  in  Cuvier  and 
Valenciennes's  figure  (t.  297)  of  T.  iris,  but  is  quite  unarmed.  The  ventral  line  is  serrulate, 
and  the  whole  surface,  particularly  towards  the  ventral  Hue.  is  finely  shagreened  or  granu- 
late, the  granulations  becoming  stronger  toward  the  ventral  line,  as  in  the  same  figure.  In 
shape  and  proportions  it  agrees  better  with  T.  taenia,  but  differs  in  several  important  par- 
ticulars from  Cuvier  and  Valenciennes's  description  of  that  fish.  The  only  individual  exam- 
ined occurred  in  June,  1845,  and  has  been  added  by  me  to  the  collection  of  the  Cambridge 
Philosophical  Society.  It  was  scarcely  quite  dead  when  I  first  saw  it,  and  was  in  the  most, 
perfect  state  of  preservation.  Another  Traehypterus  had  occurred  in  June,  1S44,  and  was 
probably  the  same  species;  but  the  example  was  unfortunately  thrown  away  by  the  person 
to  whom  it  had  been  missent  without  my  seeing  it.  It  was  said  to  have  been  about  3 
feet  long.  The  whole  body  is  pure  bright  silver,  appearing  as  if  frosted,  from  the  tine 
granulations  of  the  surface.  The  fins  are  of  a  delicate  scarlet  or  vermilion,  the  lower 
point  or  angle  of  the  caudal  being  tipped,  and  the  hinder  end  of  the  dorsal  edged,  with 
black.  On  the  sides  are  •'!  blackish  oval  or  elliptic  spots.  This  example  was  25  inches 
long  exclusive  of  the  caudal  fin,  wdiich  resembles  a  bat's  or  griffon's  wing,  and  is  erected  in 
a  fanlike  manner,  the  lower  lobe  or  portion  being  suppressed  or  undeveloped,  and  only 
indicated  by  the  presence  of  5  short  spinules  or  abortive  rays.     (Lowe.) 

This  species  is  known  from  a  single  specimen  obtained  by  Lowe  at  Madeira  in  1849,  and 
is  distinguished  from  T.  traehypterus  chiefly  by  the  fact  that  its  lateral  line  is  smooth,  as  well 
as  by  minor  characteristics.

A  Trachypterm  having  tin' dorsal  rays  smooth,  and  the  heighl  of  the  body  contained 
.">  times,  or  a  little  more,  in  its  Length. 

An  elaborate  description  taken  from  specimens  studied  at  Norwich,  Newcastle,  and 
.Montrose,  will  be  found  in  Day's  Fishes  of  Great  Britain.  This  species  occurs  from  Ice 
land  to  the  Orkneys  and  the,  shores  of  the  British  isles.  The  largesl  British  example  is  7f 
feel  long,  bul  Day  is  of  the  opinion  that  it  grows  to  a  much  larger  size. 

It  would  seem  probable  that  studies  similar  to  that  made  by  Emery  upon  the  Italian 
forms  will  result  in  uniting  with  this  species  also  T.  Buppellii  and  T.  Uopterus. 

TRACHYPTERUS  RUPPELLII,  Gunther.

smooth  dorsal  rays  and  spinous  lateral  line. 

Radial  formula:  D.  6/135;  A.  none;  0.8;  P.  10. 

Color,  silvery,  a  very  distinct  black  spot  at  the  commencement  of  the  second  fifth  of 
the  total  length;  another,  sometimes  present,  farther  hack  on  the  body. 

This  species  was  described  by  Gunther  from  a  specimen  51  inches  in  length  obtained 
somewhere  in  the  Mediterranean,  and  now  preserved  in  the  British  Museum.

Radial  formula:  D.  6-7  +  169-171;  C.  8-6;  P.  12;  A.  none;   V.  i,  7. 

Color,  silvery  white,  with  a  blackish  spot  in  the  first  fifth  of  its  length,  and  sometimes, 
according  to  Valenciennes  and  Giinther,  a  second  spot  behind  it. 

This  species,  according  to  Giinther,  closely  resembles  T.  trackypterus,  but  in  the  so Ih 

oess  of  the  dorsal  rays  is  more  nearly  related  to  T.  arcticus. 

Specimens  have  been  obtained  at  Nice,  Naples,  Toulon,  Genoa,  and  .Messina.  In  the 
opinion  of  Giglioli  it  is  very  distinct  from  the  other  Mediterranean  forms.

A  Tritclii/jitmis  characterized  by  having  the  lower  profile  of  the  trunk  much  more

Color,  silvery,  with  the  fins  red,  and  usually  two  blackish  spots  on  the  dorsal  crest  and 
five  others  upon  the  posterior  half  of  the  dorsal. 

The  type  specimen  in  the  museum  at  Genoa  has,  according  to  Giinther,  much  the  ap- 
pearance of  a  deformed  fish.     Giinther  calls  attention  to  the  fact  that  Risso  described  a

similarly  grotesquely  shaped  fish  under  the  name  of  Gfymnetrus  Miilh linniis  (Wiegmann's 
Archiv,  1840,  13),  and  Moreau,  in  his  Fishes  of  Fiance  (p.  567),  devotes  three  pages  to  an

"  Gymnetrus  repandus,  Metaxa." 

Trachypterus  repandus,  Costa,  Fauna.  Napolitana,  Pi  iscr,  pi.  ix. 

A  Trachypterus  with  the  greatest  height  of  the  body  contained  about  3i  times  in  its 
total  length  (without  caudal).  The  belly  is  sharp  and  rough,  the  caudal  peduncle  very 
slender.  The  anterior  dorsal  is  composed  of  8  rays,  the  length  of  which  is  more  than  li 
times  the  distance  between  the  tip  of  the  snout  and  the  margin  of  the  caudal;  these  rays 
have  here  and  there  upon  them  membranous  expansions.  The  ventrals  are  about  as  long 
as  the  fish,  and  the  first  ray  at  its  extremity  becomes  divided  into  -1  membranous  filaments. 

Radial  formula:  D.  S+152;  A.  none;  1".  10;  V.  7;  0.  Id. 

( !olor:  The  entire  body  is  silvery,  with  numerous  bluish-black  dots,  which,  being  placed 
more  closely  together  in  the  region  of  the  back,  form  interrupted  transverse  hands;  these 
in  the  caudal  region  completely  surround  the  body.  There  are  certain  reddish  spots  which 
mingle  with  the  blue  ones,  giving  a  rosy  tint  to  the  spots  upon  the  back.  The  tins  are 
rosj  ;  only  the  membranous  expansions  of  the  anterior  dorsal  are  black.  The  caudal  is  of 
the  same  color,  except  tin-  upper  and  lower  margins,  which  are  somewhat  clouded. 

This  form  has  been  taken  at  (Jivita  Vecchia  and  Naples,  and  has  been  seen  also  in  the 
Adriatic  A  figure  of  it  is  given  in  Gunther's  article  "Ichthyology"  in  the  Cyclopaedia 
Britannica,  and  also  in  the  Study  of  Fishes  (p.  ~>'2\).  It  is  undoubtedly  a  young  of  some, 
other  form,  but  possibly  not  of  T.  trachypterus,  since  the  small  form  described  by  Costa 
under  the  name  T.filicauda  has  been  identified  by  Emery  with  that  species.  T.  filicauda 
has  a  very  long  filament  at  the  tip  of  the  next  to  the  last  caudal  ray,  counting  from  above. 
Its  dorsal  erest  is  very  long,  but  lacks  the  membranous  expansion  noted  in  T.  repandus. 
The  ventrals  are  also  very  long.

Color,  silver  gray,  with  a  few  spots  or  streaks  of  darker  hue,  most  numerous  anteriorly. 

It  is  not  certain  that  there  is  more  than  one  species  of  h't't/aleriis,  although,  as  the  syn- 
onymy which  precedes  clearly  shows,  various  names  Lave  been  suggested  in  connection 
with  the  comparatively  \\-w  individuals  which,  during-  the  past  century  and  a  half,  have 
been  captured  in  the  North  Atlantic.  There  appears  to  be  considerable  possibility  of  indi- 
vidual variation  in  proportions  of  height  to  length,  and  in  the  number  of  rays  in  the  dorsal 
fin,  but  it  is  a  tart  well  known  to  ichthyologists  thai  constancy  is  not  to  be  expected  in 
forms  in  which  the  number  of  vertebrae  and  fin  rays  has  been  extended  far  beyond  the  nor- 
mal a\  erage. 

It  should  also  be  said  that  most  of  the  individuals  studied  have  been  in  very  imperfect 
condition,  and  also  that  in  many  instances  the  observations  have  been  made  by  untrained 
observers,  so  that  it  seems  doubtful  whether  there  is  really  more  than  one  species  to  be 
assigned  to  the  Atlantic  fauna.  At  all  events,  Giinther,  Collett,  Liitken,  and  Day  agree  in 
the  idea,  that  it  is  impossible  to  discriminate  between  the  forms  already  described,  and  we 
follow  their  lead  in  considering  them  all,  for  the  present,  as  a  single  species.  It  is  not 
impossible,  of  course,  that,  should  better  material  be  obtained,  if  may  be  desirable  to  sepa- 
rate the  group  into  more  subspecies,  but  until  this  shall  be  done  discrimination  hails  to 
confusion  rather  than  to  definite  knowledge. 

The  fishes  belonging  to  the  genus  Regalecus  are  very  remarkable,  not  only  on  account 
of  their  peculiar  appearance  and  structure,  but  because  of  their  enormous  size.  They 
have  been  known  to  attain  the  length  of  20  feet,  and  it  is  more  than  probable  that  they 
grow  very  much  longer,  and  that  many  of  the  creatures  popularly  identified  with  the  "sea, 
serpent"  are  only  large  individuals  of  this  type.  Indeed,  it  seems  quite  safe  to  assign  to 
this  group  all  the  so-called  "sea,  serpents"  which  have  been  described  as  swimming  rapidly 
near  the  surface,  with  a  horse-like  head  raised  above  the  water,  surmounted  by  a  mane-like 
crest  of  red  or  brown. 

The  individual  which  came  ashore  at  Hungry  Bay  in  Bermuda  in  1860,  and  which  was 
about  17  feet  long,  was  described  by  the  people  who  saw  it  before  its  capture  as  being 
very  much  larger,  and  as  having  a  head  of  an  immense  horse  with  a  fiaming  red  mane,  (liiu-

ther  (Challenger  Report,  xxn,  73-70)  has  in  the  most  painstaking  manner  brought  together 
a  list  of  the  specimens  taken  in  the  North  Atlantic,  as  far  as  they  are  known  to  science. 
He  mentions  14  known  upon  the  .Scandinavian  coasts  from  1740  to  1852;  19  on  the  British 
coasts  from  1759  to  1884;  1  iu  the  Mediterranean  (he  states,  however,  that  about  half  a 
dozen  specimens  have  been  observed  in  the  Mediterranean);  1  in  the  Bermudas;  3  at  the 
Cape  of  Good  Hope;  1  in  the  Indian  Ocean,  and  5  off  the  coast  of  New  Zealand. 

He  calls  attention  to  the  fact  that  of  those  observed  on  the.  British  and  Scandinavian 
coasts  4  were  observed  in  the  month  of  January,  5  in  February,  8  in  March,  2  in  April,  1 
iu  May,  1  in  June,  1  in  July,  2  in  August,  1  in  September,  and  1  in  October.  lie  also  calls 
attention  to  the  fact  that  by  far  the  greater  proportion  of  their  capture,  in  the  Northern 
Hemisphere,  at  least,  is  in  the  stormy  season. 

This  agrees  with  what  we  know  of  the  capture  of  Trachypterus,  which  likewise  seems 
to  be  brought  to  the  surface  only  by  .meat  commotions  of  the  ocean. 

The  popular  name  of  Regalecus  is  "oar-fish,"  in  allusion  to  the  blade  like  expansion  of 
the  extremities  of  the  two  ventral  tins.  Regalecus  is  also  called  in  the  books  the ''king  of 
the  herrings."  Strangely  enough,  no  representative  of  this  genns  has  been  found  along  the 
coast  of  North  America,  except  once  at  the  Bermudas. 

Gunther  is  of  the  opinion  that  the  distribution  of  this  fish  in  the  depths  of  the  sea  is 
the  same  as  that  of  Trachypterus.  The  similarity  in  their  geographical  distribution  is  quite 
remarkable.

Aulostoma  longipes,  Vaillant,  Exp.  Sci.  TravaUleur  et  Talisman,  340,  pi.  xxvn,  fig.  1. 

This  species  is  described  by  Vaillant  from  a  very  small  specimen,  Ave  millimeters  in 
length,  in  a  bad  state  of  preservation  from  off  Morocco  in  1,163  meters.  It  is  referred  by 
him  provisionally  to  the  genus  Aulostoma,  and  the  figure  would  seem  to  indicate  that  his 
identification  is  correct.     It  may  possibly  be  found  to  be  a  young  of  A.  coloratum. 

Body  elongate,  nearly  cylindrical;  its  height  about  one-ninth,  its  thickness  one-eleventh 
of  its  length.  Length  of  the  head  a  little  more,  than  one-third  of  total  length;  snout  con- 
tained two  and  one-fourth  times  in  the  length  of  the  head.  Diameter  of  the  eye  apparently 
about  one-eighth  of  the  length  of  the  head;  the  interorbital  space  almost  nothing.  No 
trace  of  scales  is  visible  upon  the  specimen,  and  the  lateral  line  is  only  indicated  by  a 
series  of  pigmentary  spots. 

In  the  place  of  the  dorsal,  Vaillant  found  only  a  very  short  fin,  placed  far  back;  and 
an  anal  exactly  similar  to  it  in  shape  and  size.  The  caudal  was  mutilated,  but  appeared 
to  Vaillant  to  have  had  no  prolonged  median  rays.  Pectorals  moderately  long.  Ventrals 
composed  (as  nearly  as  it  is  possible  to  determine)  of  6  rays,  inserted  far  back  and  extend- 
ing to  the  base  of  the  caudal,  which  is  long,  being  more  than  one-third  of  the  entire  length 
of  the  body.

As  Vaillant  indicates,  the  only  obstacle  in  the  way  of  considering  this  the  young  of  A. 
coloratum  is  the  position  and  length  of  the  ventrals,  and  the  fact  that  A.  coloratum  has 
not  been  found  in  the  eastern  Atlantic. 

Order  PEDICULATI. 

Carpal  bones  notably  elongate,  forming  a  sort  of  arm,  which  supports  the  broad 
pectorals.  Gill  openings  reduced  to  a  large  or  small  foramen,  situated  in  or  near  the  axils, 
more  or  less  posterior  to  the  pectorals.  No  scales.  Ventral  fins  jugular,  if  present;  first 
vertebra  united  to  the  cranium  by  a  suture;  epiotics  united  behind  supra-occipital;  elon- 
gate basal  pectoral  radii  reduced  in  number;  no  interclavicles;  post-temporal  broad,  flat, 
simple;  superior  pharyngeals  two,  similar,  spatulate,  with  anterior  stem  and  transverse 
blade ;  basis  of  cranium  simple.  No  air  duct  to  the  swim  bladder.  Anterior  dorsal  reduced

form,  are  well  adapted  to  life  at  great  depths.

4SG  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

Newfoundland.  The  museum  of  the  Essex  Institute  has  a  specimen  about  4  inches  in  length, 
taken  on  the  Banks  of  Newfoundland  in  1856,  by  L.  J.Johnson.  This  is  probably  the  most 
northern  recorded  occurrence  of  the  species  in  the  western  Atlantic,  except  an  unconfirmed 
statement  by  Pennant  of  its  appearance  in  Hudson's  Bay. 

It  frequents  the  moderate  depths  along  the  coast  from  Nova  Scotia  to  Virginia  and  at 
greater  depth  as  far  south  as  the  Antilles.  The  Blake  obtained  it  off  Barbados  at  a  depth 
of  209  fathoms  (station  IV),  and  at  84  fathoms  in  latitude  23°  13',  longitude  89°  10'  (station 

CCLVII). 

The  Fish  Hawk  trawled  it  at  station  826.  Another  specimen  (No.  20170),  20  centi- 
meters long,  containing  immature  ova,  was  taken  at  station  804,  at  a  depth  of  365  fathoms; 
also  a  large  specimen  with  immature  ova  (No.  26098),  from  station  870,  120  fathoms;  and  a 
smaller  one,  perhaps  two  years  old  (No.  26070),  from  station  878,  142A  fathoms. 

The  AUmtrasix  obtained  young  individuals  at  station  2025  and  station  2421. 

Giinther  has  admitted  it  to  the  list  of  abyssal  forms  on  the  authority  of  the  observations 
of  American  naturalists.  It  has  since  been  announced  that  the  Talisman  obtained  it  at 
400  to  700  meters  (stations  ex,  cxi,  cxin  a,  cxxm)  about  the  A/ores  and  Cape  Verdes.

Antennarius marmoratus. — GOnther,  Cat.  Fish.  Brit.  Mus.,  m,  187. 

A  description  of  this  species  in  its  protean  manifestations  of  form  and  color  seems 
scarcely  necessary  here,  since  its  characters  are  well  known  to  every  tyro  in  ichthyology. 

The  specimens  before  us  are  all  apparently  of  the  type  referred  to  by  Cinther  under 
the  variety  E.  (Cat.  Fish.  Brit.  Mus.,  in,  p.  187),  the  Antennarius  marmoratus  of  Cuvier 
and  Valenciennes. 

A  specimen  was  obtained  by  the  U.  S.  Coast  Survey  steamer  Blake  off  St.  Vincent,  in 
the  West  Indies  (station  m),  at  a  depth  of  404  fathoms,  and  another  by  the  U.  S.  Fish  Com- 
mission steamer  Albatross,  at  the  surface,  near  station  2108.  There  is,  of  course,  no  positive 
evidence  that  the  Blake's  specimen  actually  came  from  the  bottom.

"The  anterior  dorsal  equals  aboul  a  bhird  of  the  length  of  the  caudal  tin  and  has  al  its 
end  a  laciniated  or  Cringed  Lobe  extending  upward;  the  second  is  moderate,  slightly  curved, 
•rad  rather  longer  than  the  lirst,  and  with  a  membrane  extending  nearly  to  the  base  of  the 
third  spine;  the  latter  is  free,  extends  backward  nearly  to  the  fin,  and  almost  connected 
with  it  by  the  membrane.     The  skin  is  covered  with  minute  bifurcated  spines. 

"The  color  is  brown,  marbled  wirh  lighter,  especially  before  and  behind  the  dorsals 
and  above  the  pectorals;  distant  black  dots  arc  also  scattered  over  the  body.  Three  large 
ocelli  or  Mack  spots,  margined  with  light  brown,  are  on  each  side:  one  at  the  middle  of  I  he 
basal  half  of  the  dorsal,  a  second  below,  intermediate  between  it  and  the  anus,  and  a  third 
in  the  middle  of  the  caudal  fin.  The  floor  of  the  mouth  behind  the  tongue  is  black,  with 
whitish  yellow  radiating  lines,  while  the  tongue  itself  is  light  brown,  with  darker  radiating 
bands  or  spots.''     (  Grill.) 

This  species  is  probably  pelagic  and  not  abyssal.

488  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

Descriptions  and  measurements  of  No.  2(>0l!l  may  be  found  in  Goode,  loc.  tit.  Although 
there  is  ample  material  and  some  of  the  specimens  in  the  National  Museum  are  very  Large, 
fuller  study  seems  unnecessary,  since  they  are  undoubtedly  Lowe's  G.  pictus. 

The  following  color  notes  were  taken  by  Dr.  Beau  from  a  fresh  specimen  taken  in  trawl, 
station  li.3.57.  January  22,  L885. 

Back  greenish  gray,  mottled  with  brown  and  tinged  with  rosy,  supraocular  region  with 
golden  reflections.  Pectorals  lemon  yellow  mingled  with  rosy;  caudal  like  pectorals. 
Sides  rosy,  ruder  surface  whitish  and  rosy  intermingled.  Pupil  intense  blue.  Back  with 
fine  reticulations.  Rostral  tentacle  greenish  gold  at  base,  the  fimbriated  portion  lavender. 
Lines  of  mucous  pores  with  reddish  brown,  well  distinguished  from  the  remaining  colors. 
Labial  fringes  lemon  yellow.     Iris  golden  or  rather  lemon  yellow. 

The  species  inflates  its  abdomen  like  Tetraodon  and  has  some  difficulty  in  expelling  the 
air  so  as  to  sink  rapidly.  The  small  gill-openings  are  closed  very  tightly  during  inhalation 
and  a  strong  current  of  water  is  expelled  in  expiration. 

Family    CERATIID^E. 

Ceraliida,  Gill,  Proe.  Acad.  Nat.  Sci.  l'liila..  1863,89;  Air.  Fain.  Fish..  1872,  2  (No.  f-'i:  Proc.  1'.  8.  Nat.  Mas., 
i.  1878,  pp.  L'li;.  L'i'T. 

l'edieulates  with  head  and  body  compressed.  Mouth  terminal,  mine  or  less  oblique. 
Gill-openings  small,  in  the  lower  part  of  the  axils.  No  pseudo-branchiae.  Spinous  dorsal 
represented  by  at  least  a  frontal  and  superior  rostral  spine.  Pectoral  members  not  genicu- 
hited,  with  short  pseudobrachia  and  three  actinosts.  Xo  ventral  tins.  All  known  forms 
are  uniform  blackish  in  color. 

"The  'bathybial  sea  devils.'"  writes  Giinther,  ••are  degraded  forms  of  Lophius;  they 
descend  to  the  greatest  depths  of  the  ocean.  Their  hones  arc  id' an  extremely  light  and 
thin  texture,  and  frequently  other  parts  of  their  organization,  their  integuments,  muscles, 
and  intestines  are  equally  loose  in  texture  when  the  specimens  are  brought  to  the  surface. 
In  their  habits  they  probably  do  not  differ  m  any  degree  from  their  surface  representative, 
Lophius. 

••When  the  first  individuals  of  this  group  were  discovered  they  seemed  to  be  suffi- 
ciently distincl  from  one  another  to  just  i t  \  generic  separation.  However,  the  additions  of 
recent  years  exhibit  that  variation  in  the  shape  of  the  body.  head,  and  mouth,  in  the 
specialized  dorsal  spines,  and  in  the  development  of  dermal  scutes,  which  may  be  expected 
in  such  grotesquely  formed  creatures. 

"The  number  of  the  dorsal  spines  is  always  reduced,  and  at  the  end  of  the  series  of 
these  species  only  one  spine  remains,  with  a  simple,  very  small  lamella  at  the  extremity 
i.Mi  Iiihoii  Ins  Johnsonii,  Melanoeetus  Murrayi).  In  other  forms  sometimes  a  second  cephalic 
spine,  sometimes  a  spine  on  the  back  of  the  trunk  is  preserved.  The  first  cephalic  spine 
always  retains  the  original  function  of  a  lure  for  other  marine  creatures,  but  to  render  it 
more  effective  a  special  luminous  organ  is  sometimes  developed  in  connection  with  the 
filaments  with  which  its  extremity  is  provided  [Ceratias  bispinosus,  Oneirodes  Eschrichtii). 
So  far  as  it  is  known  at  present  these  complicated  tentacles  attain  to  the  highest  degree 
of  development  in  Himemtolophus  and  fflgceonichthys.  In  other  species  very  peculiar  dermal 
appendages  are  developed,  either  accompanying  the  spine  on  the  back  or  replacing  it. 
They  may  be  paired  or  form  a  group  of  three;  are  pear-shaped,  covered  with  the  common 
skin,  and  perforated  at  the  top,  a  delicate  tentacle  sometimes  issuing  from  the  foramen.''

Mancalias  was  first  taken  by  II.  M.  S.  Challenger,  at  a  depth  of  2,400  fathoms,  in  the 
Middle  Atlantic, between  the  Canary  and  Cape  Verde  Islands.  The  specimen,  -'<\  inches 
Ions',  and  indifferently  preserved,  is  in  the  British  Museum. 

The  specimen  is  '.)(»  millimeters  in  length  from  the  snout  to  the  end  of  the  tail,  com 
pressed  laterally,  and  of  a  uniform  black  color.  The  anterior  spine  of  the  first  dorsal  tin  is 
produced  into  a  long  filament,  ending  in  a  pear-shaped  bulb,  terminating  in  a  very  distinct, 
semitransparent,  whitish  spot.  This  spine  has  its  origin  on  the  posterior  portion  of  the 
bead,  and  when  laid  hack  it  reaches  nearly  to  the  tip  of  the  tail.  The  second  pari  of  the 
first  dorsal  is  placed  far  back  on  the  body,  and  consists  of  1'  short,  fleshy  tubercles,  which 
lie  in  a  depression  in  front  of  the  second  dorsal  tin.  The  second  dorsal  has.",  rays;  the  anal 
is  opposite  the  second  dorsal  and  has  I  rays;  the  caudal  has  M  rays,  the  1  central  rays  being 
much  larger  than  the  others,  and  bifid.  The  pectorals  are  small  and  have  1"  very  delicate 
rays.  The  gill  opening  is  a  slit  situated  below  the  pectoral  tin.  The  upper  jaw  is  formed 
by  the  intermaxillaries,  and  is  armed,  together  with  the  lower  jaw,  with  a  series  of  teeth  of 
moderate  size,  which  can  be  depressed  inward  as  in  Lophiits.  The  skin  is  thickly  covered 
with  minute,  embedded,  conical  spines.  The  eyes  are  very  small  and  are  placed  high  up  on 
the  middle  of  the  head. 

The  presence  of  a  lish  of  this  group  a1  so  great  a  depth  is  of  special  interest.  From 
its  structure,  and  from  the  analogy  of  its  nearest  allies,  there  seems  to  be  no  reasonable 
doubt  that  it  lives  on  the  bottom,  it  is  the  habit  of  many  of  the  family  to  lie  hidden  in  the 
mud,  with  the  long  dorsal  filament  and  its  terminal  soft  expansion  exposed.  It  has  been 
imagined  that  the  expansion  is  used  as  a  bait  to  allure  its  prey,  but  it  seems  more  likely 
that  it  is  a  sense  organ,  intended  to  give  notice  of  their  approach.

Ceratias  Shufeldti,  Gunther,  Challenger  Report,  xxn.  54. 

The  specimens  of  Mancalias  obtained  in  the  Western  Atlantic  are  two  in  number. 

A  single  specimen,  No.  26159,  85  millimeters  Ions',  was  taken  October  2,  L880,  at  sta- 
tion  No.  893,  at  a  depth  of  372  fathoms.     (Goode,  Proc.  I.  S.  Nat.  .Mas.,  in,  419.) 

The  type  of  Typhlopsaras  Shu/eldtii  (No.  33552,  U.  S.  Nat.  Mus.),  has  the  maxilla  one- 
third  the  length  from  the  sill  opening  to  the  caudal  base;  the  iiitermaxilla  is  contained  3i

limes  iii  ili is  length.    This  form  is  more  Blender  than  thai  figured  by  Giinther,  and  1ms  five 
rays  in  the  dorsal,  and  apparently  fifteen  in  the  pectoral. 

There  are  no  vomerine*.  The  intermaxillary  and  mandible  arc  armed  with  a  narrow 
baud  of  depressible  teetb  of  various  lengths.  The  skin  has  a  fine  granular  appearance 
and  is  every  where  covered  with  minute  prickles.  The  median  dermal  caruncle  referred  to 
in  the  description  of  this  species  has  been  torn  off.  The  caruncles  are  only  2  in  number 
and  situated  as  in  M~ancalia&  uranoscopus,  as  figured  in  the  Challenger  Fishes.  The  length 
of  the  dorsal  spine,  without  the  joint  bearing  the  pear  shaped  appendage,  equals  the  dis- 
tance from  the  gill  opening  to  the  root  of  the  tail;  the  joint  bearing  the  appendage  is 
two  fifths  of  this  distance.  The  length  of  the  specimen  at.  present  is  about  2:;  inches.  In 
Mancalias  uranoscopus  (26159)  the  first  dorsal,  without  the  joint  bearing  the  appendage, 
contains  the  distance  from  the  i;ill  opening  to  the,  root  of  the  tail  1  j  times.  The  joint  con- 
taining the  appendage  is  one-halt  as  long  as  the  distance  from  the  gill  opening  to  the  root 
of  the  tail.  The  dermal  caruncles  are  distant,  from  the  dorsal  a,  space,  equal  to  one-si\th  of 
the  distance  from  the  gill  opening  to  the  root  of  t he  tail.  In  Typhlopsaras  Skufeldtii  the 
caruncles  are  placed  at  a  distance  from  the  dorsal  a  space  contained  4£  times  in  the  dis- 
tance from  t  he  gill  opening  to  the,  root  of  the  tail. 

In  the  specimens  described  by  Uoode and  Hennas  Mniiciiliiis  unoioscopus  (No.  26159), 
the  length  '■>]  inches,  the  length  of  the  maxilla  is  one-third  the  length  from  the  gill  opening 
to  the  rooi  of  I  he  tail,  and  the  intermaxilla,  34  times  in  the  same  distance.  The  teeth  in  the 
jaws  are  depressible,  in  narrow  bands,  and  of  unequal  size.     The  vomer  is  toothless. 

There  are  two  small  caruncles  not  far  from  the  front  of  the  dorsal  tin,  and  instead  of 
being  placed  opposite  each  other,  according  to  the  usual  arrangement,  one  is  placed 
behind  the  other.  The  skin  is  covered  with  minute  granules  or  papilla-,  each  one  sur- 
mounted by  a  slender  prickle,  as  in  Typhlopsaras. 

The  pectoral  of  this  individual  contains  15  rays.  The  pectorals  of  T.  Shufeldtii  are 
imperfect. 

In  the  note  published  by  Dr.  Goode  in  Proceedings  U.  S.  Nat.  Mus.,  vol.  in,  L881, 
469,  the  length  of  this  specimen  is  stated  to  be  185  millimeters,  which  is  a  misprint  for  85 
millimeters.

492  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

NOTES   ON  THE  TYPE   SPECIMEN. 

The  type  of  Cryptnpsaran  Gouesii,  at  present  is  only  35  millimeters  long',  the  caudal  being 
imperfect.  The  length  without  caudal  is  .'50  millimeters  and  contains  the  greatest  height 
2J  times.  The  bulb  on  the  dorsal  spine  when  laid  backward  can  be  made  to  reach  the 
dermal  caruncles  on  the  back.  The  length  of  the  upper  jaw  is  about  one-fourth  of  the 
length  without  caudal.  The  gill  opening  is  nearly  midway  between  the  front  of  the  head 
and  the  root  of  the  tail.  The  mouth  is  placed  vertically.  The  intermaxillary  teeth  occupy 
about  the  entire  length  of  the  bone.  The  uiandibulary  teeth  are  very  unequal  in  size.  At 
the  symphysis  of  the  mandible  there  is  a  pair  of  minute  spines  closely  connected  at  the 
base  and  slightly  separated  at  the  extremity. 

Specimen  No.  39483  is  58  millimeters  long;  47  millimeters  to  base  of  caudal.  The 
greatest  height  is  contained  in  the  length  without  caudal  2§  times.  The  gill  opening  is  a 
little  nearer  to  the  end  of  the  caudal  than  to  the  front  of  the  head.  The  distal  portion  of 
the  dorsal  spine  is  about  one-half  the  length  without  caudal.  The  median  dermal  caruncle 
is  very  much  larger  than  the  two  lateral  ones. 

The  skin  is  covered  with  minute  granules  of  uniform  size.  The  pectoral  coutaius  16 
lays;  its  length  is  about  one-fifth  the  length  of  the  head.  The  length  of  the  upper  jaw  is 
about  one-fifth  of  the  total  without  caudal.  The  pair  of  spines  at  the  symphysis  of  the 
mandible  is  replaced  by  a  Aery  small  knob.  The  teeth  in  the  intermaxillary  are  all  very 
small,  diminishing  in  number  towards  the  symphysis;  they  are  apparently  uuiserial. 

On  each  side  of  the  head  of  the  vomer  there  are  two  or  three  depressible  teeth;  the 
palatines  seem  to  be  wanting. 

We  have  seen  something  like  traces  of  similar  teeth  on  the  vomer  of  Mancalias  Sh  ufeldtii, 
but  owing  to  the  condition  of  the  specimen  can  not  be  certain  about  this  character.

fect one,  23  inches  long,  obtained  off  the  coast  of  Greenland  about  1837. 

CORYNOLOPHUS,  Gill. 

Corynolophus,  Gill,  Proc.  U.  S.  Nat  Mns.,  i,  1878,  2'J.l;  v,  1883,  551. — (LC'tkex,  Vidensk.  Medd  fra  den  Natur- 
hist.  Foren.,  Copenhagen,  1879-'80,  <J7,  08.) 

Ceratiids  resembling  Himantolophus  but  having  the  body  short-oval;  dorsal  with  '<  rays; 
pectoral  with  about  7. 

Dr.  Gill,  replying  to  certain  strictures  as  to  the  validity  of  this  genus,  made  by  Lutken, 
states  that  the  distinction  alleged  to  exist  between  Himantolophus  and  Corynolophus  are 
very  marked,  and  quite  sufficient  to  justify  two  genera.  He  forcibly  remarks  that  there  is 
no  reason  except  the  singularity  and  greatness,  of  the  differences  specified^  for  doubting  the 
correctness  of  Eeinhardt's  observations.

Corynolophus  Beinhardtii,  (Jill.  Proc.  U.  S.  Nat.  Mns.,   i.  1878,  227;  \.  1883,  551. 

The  body  is  short  oval,  its  height  three-fourths  its  length.  The  dorsal  fin  has  5 rays, 
the  pectoral  17.  The  cephalic  ray  is  provided  with  about  8  tentacles.  The  body  armed 
with  prickly  scales,  sparingly  distributed. 

A  single  specimen,  It  inches  long,  is  known  from  the  coast  of  Greenland.

Ceratiids  with  body  and  head  depressed,  mouth  with  the  cleft  vertical,  or  inclined  for- 
ward, and  mandibular  articulation  under,  or  in  advance  of  snout.     (Gill.) 

This  is  a  form  closely  allied  to  Himantolophus,  and  excelling  it  in  grotesqueness.  It 
is  represented  by  a  single  species,  A.  Appelii,  Clarke  [loc.  <-it.,  p.  245,  pi.  vi),  obtained  in 
the  deep  sea  off  New  Zealand.  Giinther  gives  interesting  details  about  the  head  of  the 
cephalic  spine,  which  is  phosphorescent  and  a  lure  for  other  abyssal  animals.  (See  Chal-

Ceratiids  "with  naked  skin;  with  very  large  mouth,  having  a  subvertical  cleft;  with  no 
second  dorsal  spine;   with  branchial  arches  unarmed  and  branchial  in  2.\  pairs. 

MELANOCETUS  JOHNSONII,  GOnther.     (Figure  i06.) 

Melanocetu*  Johnsonii,  GOnther,  Proc.  Zool.  Soc.  London.  1864,  301,  pi.  25. — Study  of  Fishes,  1880,  473,  fig. 
I'll;  Challenger  Report,  xxu,  57. — Gill,  loc.  'it. 

A  single  specimen,  3.8  inches  long,  is  known.  It  was  obtained  by  Mr.  Johnson  at 
Madeira,  and  had.  it  is  said,  a  Scopelus  lh  inches  long  and  1  inch  high,  rolled  up  in  a  ball 
in  its  stomach. 

"  This  singular  fish,"  says  Gunther,  "is  distinguished  by  a  greater  disproportion  of  the 
various  parts  of  its  body  than  is  found  in  the  other  genera  of  the  family  to  which  it  belongs. 
'fhe  head  is  of  tetrahedral  form  and  is  the  most  extensive  part  of  the  whole  animal.  The 
gape  is  enormous,  and,  although  the  lower  jaw  is  vertical  when  the  mouth  is  closed,  it  can 
be  moved  downwards  at  more  than  a  right  angle.  The  lateral  extensibility  of  the  mouth 
is  not  less  than  the  vertical,  so  that  the  prey  which  can  be  received  within  the  cavity  of 
the  mouth  actually  may  exceed  the  size  of  the  fish  itself.  This  enormous  head  is  followed 
by  a  very  small  trunk  and  tail,  the  length  of  both  being  less  than  the  depth  of  the  head. 
As  the  trunk  would  not  offer  sufficient  room  for  an  addouiinal  cavity  corresponding  in  size

to  tlic  [>rey  swallowed,  this  easily  is  suspended  as  a  large  sac  from  the  lower  part  of  the 
body,  and  Boats  in  the  water.  The  upper  and  lower  jaws  arc  armed  with  a  series  of  teeth, 
which  are  very  unequal  in  length,  some  being  very  long,  others  small,  all  are  verj  slender, 
and  can  be  depressed  toward  the  inside  of  the  mouth.  This  peculiarity  of  the  teeth  inaj 
be  observed  in  the  Lophius,  in  the  pike,  and  numerous  other  rapacious  fish  with  long  slender 
teeth.  The  vomer  is  armed  «  ifh  a  transverse  series  of  single  teeth,  and  extends  across  the 
whole  width  of  the  roof  of  the  mouth;  the  palatines  ami   pterygoid   teeth  are  situated  at 

some  distance  behind  the  v sr,  and  form  two  bundles  irregular  in   form.    The   pharynx 

anil  oesophagus  are,  as  might  be  expected,  very  wide.  The  eye  is  situated  high  up  on  the 
side-  of  the  head:  it  is  very  small,  covered  by,  but  appearing  through,  the  skin.  There  are 
no  nasal  openings.  The  opercular  pieces  are  reduced  to  styliform  rudiments;  there  are  5 
branchiostegals.  Only  the  three  inner  branchial  arches  bear  short  branchial  lamellae, 
which  are  disposed  in  a  double  series  on  the  two  middle  ones,  and  in  a  single  one  on  the 
innermost  arch.  The  gill  opening  itself  is  a  slit  of  moderate  width,  below  and  behind  the 
pectoral  tin.  The  upper  surface  of  the  head  is  concave,  and  in  the  middle  of  its  anterior 
portion  there  is  situated  the  single  filament  to  which  the  anterior  dorsal  fin  is  reduced; 
this  filament  is  more  than  half  as  high  as  the  head,  and  dilated  into  a  small  lamella  at  its 
extremity.  The  second  dorsal  fin  occupies  the  back  of  the  tail,  and  is  composed  of  14 
simple  rays,  none  of  w  Inch  are  as  high  as  the  fin  is  long.  The  caudal  tin  is  quite  free  from 
the  dorsal  and  anal,  and  composed  of  s  very  soft  rays,  which  are  bifid  at  the  end,  and 
form  a  convex  posterior  margin.  Anal  tin  very  short,  composed  of  4  rays  only,  which  are 
opposed  to  the  posterior  dorsal  rays.  The  base  id'  the  pectoral  tin  is  fleshy  and  enveloped 
in  skin,  as  in  other  Pediculati.  It  is  composed  of  18  simple  and  feeble  rays.  Ventral  tins 
none.  Vent  situated  immediately  behind  the  abdominal  sac.  The  whole  fish,  even  the 
inside  of  the   mouth   of   the  abdominal  sac   and  of  the  stomach,  is  of  a  uniform  black. 

Total  length  (mouth  closed),  3.8  inches;  length  of  intermaxillary  and  of  mandible,  1.4 
inches.1 

LIOCETUS,  Glinther. 

Lioeetua  [subgenus],  Gunther,  Challenger  Report,  xxn,  1887,57.     [Type,  Melanocetus  Murrayi,  Oiinther.] 
The  subgenus  I/iocetus  of  Gunther  differs  from  Melanocetus  chiefly  in  the  absence  of 
vomerine  teeth.

Melanocetus  {Liocetua)  Murrayi,  Gunther  Challenger  Report,  \.\n,  1887,  pi.  xi,  fig.  a. 

Extremely  similar  to  Melanocetus  Johnsonii,  but,  singularly,  there  is  no  trace  of  vo- 
merine teeth,  whilst  there  is  no  distinction  between  the  two  species  as  regards  the  den- 
tition of  the  jaws.  The  posterior  angle  of  the  mandible,  projects  more  and  forms  a 
salient  point.  The  mouth  is  comparatively  less  wide,  and  the  maxillary  considerably  shorter, 
being  about  two-fifths  of  the  total  length,  without  caudal,  whilst  it  is  rather  more,  than  one- 
half  in  the  Madeiran  species.  Eye  rudimentary.  One  cephalic  spine,  which  is  shorter  than 
the  maxillary.  The  last  dorsal  ray  is  connected  by  a  short  and  delicate  membrane  with 
the  caudal  tin;  most  of  the  caudal  lays  are  bind,  the  longest  shorter  than  the  maxillary. 
Pectoral  tin  as  much  developed  as  in  .1/-  lanoa  tus  Johnsonii.

IAnophryne,  Collett,  Proc.  Zo<">1.  Soo.  London,  1886,  138. — Gunthkr,  Challenger  Report,  xxn,  57. 

"  Linophryne"  says  Giinther,  "differsfrom  Melanocetus  in  possessing  a  long  tentacle 
at  the  throat."    Collett's  original  description  is  as  follows: 

Head  enormous;  the  body  slender,  compressed,  month  oblique.  Spinous  dorsal 
reduced  to  a  single  cephalic  tentacle,  the  basal  part  of  which  is  erect,  not  procumbent. 
Teeth  in  the  jaws  on  the  vomer  and  the  upper  pharyngeals.  Gill  openings  exceedingly 
narrow,  situated  a  little  below  the  root  of  the  pectoral.  Soft  dorsal  and  anal  very  short; 
ventrals  none.  Abdominal  cavity  forming  a  sac,  suspended  from  the  trunk.  Skiu  smooth; 
a  long  tentacle  on  the  throat. 

LINOPHRYNE  LUCIFER,  Collett.     (Figure  408.)

xxn,  57. 

A  spinous  projection  above  each  orbit.  Cephalic  tentacle  black,  with  a  large  ovate 
bulb,  the  upper  half  of  which  is  white;  gular  tentacle  much  larger,  terminating  in  two 
ton  one  like  appendages,  which  are  furnished  on  the  upper  edge  with  a  row  of  round,  white 
papilla-. 

Radial  formula:  D.  1/3;  A.  2;  C.  0;  P.  14-15. 

Collett  tells  the  history  of  its  capture  as  follows: 

A  single  specimen,  with  a  total  length  of  4!»  millimeters,  was  caught  by  Capt.  P. 
Andresen  in  May,  1877, floating  in  the  sea  (about  30°  N.  hit.,  20°  W.  Ion.),  3  degrees  north- 
west of  Madeira,  and  was  presented  to  the  museum  of  the  Christiania  University.  During 
several  years  it  remained  unnoticed  in  the  private  house  of  the  late  director  of  the  Christ  i 
ania  museum,  Prof.  Esmark,  but  after  his  deatli  it  was  returned  to  the  museum  (December, 
1885). 

Mr.  Andresen,  who  is  now  residing  in  Christiania,  reports  to  me  that  on  the  day  men- 
tioned he  was  on  a  voyage  to  the  West  Indies.  He  was  capturing  turtle  in  his  boat;  there 
was  a  heavy  swell,  but  the  water  was  smooth.  After  a  time  he  caught  sight  of  this  little 
black  fish,  which  lay  on  the  surface  quite  alive,  but  almost  motionless,  which  was  not  sur- 
prising when  it  was  discovered  that  it  had  just  swallowed  a  fish  longer  than  itself.  It  did 
not  lie  on  its  side,  but  was  apparently  unable  to  swim  away.  By  getting  the  bailer  under 
it  he  lifted  it  out  with  ease,  and  in  order  to  keep  it  fresh  he  gave,  up  his  search  for  turtle 
and  rowed  to  the  ship,  where  it  was  placed  in  spirits  for  preservation. 

CAULOPHRYNE,  Goode  and  Bean,  n.  g. 

Head  large,  compressed.  Mouth  with  the  cleft  nearly  horizontal.  Body  short,  much 
compressed.  Spinous  dorsal  reduced  to  a  single  cephalic  tentacle,  which  is  supported  on  a 
short  procumbent  base.  Teeth  of  unequal  size  in  the  intermaxillary  and  the  mandible. 
Vomer,  palatines,  and  upper  pharyngeals  toothed.  Gill  openings  narrow,  horizontal  slits 
placed  below  and  in  front  of  the  root  of  the  pectorals.  Branchiae  in  i-2-i  pairs.  Branchial 
arches  armed  with  dentigerous  tubercles.  Skin  naked.  Numerous  luminous  filaments  on 
head  and  body.  Soft  dorsal  and  anal  many  rayed;  the  rays  greatly  produced.  Caudal 
long,  tapering.  Ventrals  none.  Pectorals  very  broad,  sessile,  postmedian,  under  dorsal  fin, 
with  numerous  rays.  Pyloric  appendages  reduced  to  one  small  rudiment.  Air  bladder 
absent. 

CAULOPHRYNE  JORDANI,  Goode  and  Bean,  n.  s.     (Figure  409.) 

The  height  of  the  body  is  nearly  one-half  of  the  total  length  without  caudal,  the  greatest 
height  occurring  just  behind  the  head.  The  cephalic  appendage  has  a  pale  tuft  at  its  tip. 
The  length  of  the  distal  portion  of  the  appendage  equals  one-third  of  the  total  length  with- 
out the  caudal.     The  tuft  is  somewhat  mutilated,  but  it  shows  no  evidence  of  a  laminated

structure.  The  basal  portion  of  the  cephalic  appendage  is  about  twice  as  long  as  the  very 
small  eye.  The  maxillary  is  a  very  slender,  narrow  bone,  extending  about  as  far  backward 
as  the  intermaxillary.  The  intermaxillary  is  slightly  protractile  and  has  about  lu  teeth 
mi  each  side,  several  of  which  are  nearly  twice  as  lame  as  the  rest  ;  its  length  is  two-fifths 
of  the  total  without  caudal.  The  mandible  is  as  long  as  the  head  without  the  snout;  it  has 
8  teeth  on  each  side,  the  anterior  pair  and  several  other  pairs  along  the  shaft  of  the 
bone  being  greatly  enlarged.  A  pair  of  enlarged  teeth  on  the  head  of  the  vomer;  several 
similar  teeth  on  the  palatines.  Upper  pharyngeals  armed  with  several  strong  teeth.  The 
ej  e  very  small,  inconspicuous;  its  distance  from  the  tip  of  the  snout  equals  nearly  one  third 
its  distance  from  the  origin  of  the  soft  dorsal.     Intestine  shorter  than  length  w  ithout  caudal. 

The  soft  dorsal  has  Hi  rays,  all  of  which,  except  the  last  four,  are  greatly  produced; 
the  second,  third,and  fourth  rays, are  the  longest;  they  are  nearly  twice  as  long  as  the 
body.  The  anal  consists  of  11  rays,  all  of  which,  except  the  last  three,  are  much  produced. 
The  tin  is  not  quite  perfect,  yet  its  anterior  rays  are  longer  than  the  body.  The  caudal 
contains  8  rays,  of  which  the  four  inner  ones  are  divided,  while  the  test  are  simple.  The 
middle  rays  are  as  long  as  the  distance  from  the  tip  of  the  lower  jaw  to  the  base  of  the 
pectoral.  The  pectoral  is  comparatively  short  and  contains  1G  simple  articulated  rays, 
the  longest  of  which  is  about  one  half  as  long  as  the  head. 

About  9  luminous  filaments  on  each  sideof  the  head,  7  more  between  the  nape  and 
the  dorsal,  and  about  12  on  the  sides.     The  filaments  are  nearly  twice  as  long  as  the  eye. 

Head  and  body  black;  caudal  cephalic  tuft,  and  most  of  the  lin-rays  pale. 

The  type  of  the  species  is  number  39265,  taken  by  the  steamer  Albatross,  {September

This  species,  first  described  by  Mitchill  from  the  straits  of  Bahama,  was  also  described 
by  Richardson  from  a  specimen  presented  to  him  by  Audubon,  professedly  from  Labrador, 
but  more  probably  belonging  to  the  South  Carolina  collection  transmitted  at  the  same  time. 
Richardson's  type,  now  in  the  British  Museum,  was  carefully  studied  by  Dr.  Bean,  whose 
measurements  are  appended. 

Jordan  is  of  the  opinion  that  this  species  is  a  form  of  M.  vesper/ i  I  in,  a  conclusion  which 
does  not  seem  untenable  when  we  consider  the  immense  variation  of  individuals  which  has 
forced  even  the  conservative  Giinther  to  bring  together  as  identical  the  forms  described  by 
Cuvier  and  Valenciennes  as  Malthea  longirostris,  M.  nasuta,  M.  notata,  .1/.  aiigusta,  and  M. 
truncata. 

Giinther  was  doubtless  influenced  by  the  supposed  difference  of  locality  to  leave  M. 
radiata  in  a  separate  species. 

Appended  are  measurements  of  the  typical  example  and  of  an  individual  of  nearly 
equal  size  from  Pensacola,  Florida.  The  species  is  not  uncommon  ou  the  east  coast  of  Flor- 
ida, but  has  only  once  been  recorded  from  Labrador.  The  type  was  presented  to  Sir  John 
Richardson  by  Audubon,  who  may  have  been  misinformed  as  to  its  origin. 

In  the  Pensacola  example,  No.  31908,  the  dorsal  surface  of  the  body  is  dark  gray,  with 
numerous  small,  roundish  black  spots  having  a  whitish  origin.  The  under  surface  is  light 
gray.  The  largest  body  spots  are  one-fourth  as  long  as  the  eye.  The  upper  side  of  the 
pectorals  have  spots  similar  to  those  of  the  body,  but  more  elongate  and  irregular.  The 
cheeks  are  spotted  like  the  sides  of  the  body.  The  tubercles  are  largest  and  most  numerous 
along  the  dorsal  surface  of  the  body.  The  caudal  peduncle  is  thick  and  heavy.  The  nasal 
tentacle  is  trilobate  at  the  tip.  The  posterior  nostril  is  more  than  twice  as  large  as  the 
anterior,  which  has  a  rudimentary  tube.  The  teeth  are  in  villiform  bauds  on  the  vomer, 
palatines,  and  in  the  jaws.    The  vent  is  behind  the  middle  of  the  length  to  caudal  base. 

Upon  examinatiou  of  the  measurement  table  it  will  be  apparent  that  the  actual  differ- 
ences between  the  two  examples  are  so  slight  as  to  remove  all  doubt  concerning  their 
specific  identity.

HALIEUTELLA,  Goodeand  Bean. 

Halieutella,  Goode  and  Bean,  Froc.  Biol.  Soc.  Washington,  n,  1882,  88. 

Body  maltheiform,  subcircular,  depressed,  its  width  equal  to  its  length;  covered  with 
flaccid,  inflatable  skin.  Spines  feeble  and  less  numerous  than  in  Halieuttea.  Head  merged 
in  body;  forehead  with  a  transverse  bony  ridge;  no  perceptible  supraoral  cavity;  no  ten- 
tacle. Mouth  small,  terminal;  lower  jaw  slightly  curved  forward.  Teeth  in  the  jaws 
minute,  cardiform;  not  discernible  on  palate,  though  possibly  present.  Carpus  broad, 
slightly  exserted.  Pectoral  fins  remote  from  tail,  obliquely  placed,  with  membranes  sub- 
vertical.  Branchial  aperture  posterior  to  carpus,  upon  the  disk,  and  not  remote  from  its 
margin.  Grills  2J.  Teeth  on  palate.  Dorsal  tin  5-rayed,  inserted  at  junction  of  disk  with 
caudal  peduncle.     Anal  flu  4-rayed,  originating  at  root  of  caudal  peduncle. 

HALIEUTELLA  LAPPA,  G :  and  Beau.     (Figures  412,  A,  B.) 

Halieutella  lappa,  Goode  and  Bean,  loc.  vil. 

Disk  subcircular,  more  than  two-thirds  as  long  as  the  body.  Body  covered  with  a 
loose,  flaccid,  inflatable  skin,  which  so  obscures  its  proportions  that  it  is  impossible  to  de- 
termine its  exact  height,  but  it  is  not  nearly  so  much  depressed  as  in  the  related  genera. 
When  the  body  is  inflated  the  height  and  length  of  the  disk  are  nearly  equal. 

Spines  rather  feeble ;  about  10  between  snout  and  dorsal  fin.  About  (!  strong  spines,  witli 
conical  bases  and  stellular  tips  on  the  outer  margin  of  the  disk  on  each  side,  the  anterior 
of  them  being  opposite  the  eye.  In  front  of  these  spines  on  the  discal  margin,  and  between 
them  and  the  snout,  are  several  small,  simple  spines,  pointing  backward.  Belly  armed 
with  spines  similar  to  those  on  the  back,  but  weaker.  A  stellate  spine  upon  the  tip  of  the 
snout,  with  two  weaker,  simple  spines  on  each  side.  Nasal  openings  midway  between  eye 
and  tip  of  snout.  Mouth  small,  upon  the  margin  of  the  disk.  The  upper  jaw  is  shorter  than 
the  diameter  of  the  eye.  Teeth  as  described  in  the  generic  diagnosis.  Dorsal  fin  inserted 
at  posterior  limit  of  disk,  with  five  simple,  articulated  rays,  its  longest  ray  one-fifth  as  long 
as  the  disk.  Anal  fin  with  four  simple,  articulated  rays,  inserted  directly  beneath  the 
fourth  ray  of  the  dorsal;  its  second,  and  longest,  ray  one-fourth  as  long  as  the  disk.  Caudal 
twice  as  loug  as  anal,  and  slightly  longer  than  caudal  peduncle,  with  nine  simple,  articu- 
lated rays.  Carpus  inserted  at  a  distance  from  the  snout  equal  to  twice  the  length  of  the 
longest  pectoral  ray,  which  is  slightly  greater  than  the  distance  of  posterior  margin  of 
carpus,  at  its  junction  with  disk,  (torn  vent.  Number  of  pectoral  rays,  15.  Ventral  in- 
serted at  a  point  equidistant  from  the  snout  and  the  origin  of  theanal;  length  of  its  longest

Mus.,  851. 

A  species  of  Dibranchus  with  orbicular  disk,  nearly  as  wide  as  long;  its  length  about 
half  that  of  the  body;  its  lateral  outline  prolonged  on  each  side,  and  terminating  in  a  strong 
spine,  armed  at  the  tip  with  a  group  of  irregularly  arranged  acicular  spinelets.  Body  cov- 
ered above  with  numerous  stout,  conical  spines  with  stellular  bases.  These  are  largest 
upon  the  trunk,  where  they  are  approximately  arranged  in  about  four  irregular  longitudinal 
rows  upon  each  side  of  the  dorsal  fin.  Closely  set.  rows  of  these  stout  spines  mark  the  outer 
margin  of  the  disk,  and  there  is  also  a  cluster  of  live  to  seven  upon  each  carpal  peduncle. 
Outside  of  these  marginal  spines,  upon  each  side,  is  an  irregular  marginal  row  of  five  de- 
pressed, knife-like  spines,  each  tipped  with  a  crown  of  three  acircular  spinelets.  On  the 
anterior  margin  of  the  disk  the  two  rows  coalesce  to  a  greater  or  less  extent  and  form  a 
bristling  array  of  closely  set  spines,  some  pointing  dorsally,  some  laterally,  some  veutrally. 
There  are  two  kinds  of  spines  upon  the  dorsal  surface,  in  addition  to  the  large  ones  already 
described;  some  large,somewhat  remote  from  each  other,  conical,  stellular;  others,  much  more 
numerous  and  tilling  the  interspaces,  prickle-like,  stellular.  Belly  armed  with  numerous 
closely  set  spines  of  a  similar  kind.  Snout  somewhat  projecting,  armed  with  three  many- 
tipped  spines.  A  spine-armed  ridge  in  front  of  the  eyes,  over  the  top  of  the  snout.  In  this 
4  spines  are  conspicuous,  one  in  front  of  each  eye,  and  between  these  alarger  pair,  in  front 
of  the  supraorbital  ridges.  From  these  last-mentioned  spines  extend  spine-armed  ridges 
along  the  upper  margins  of  each  orbit.  Under  the  snout  is  a  cavity  (horizontal  diameter 
i  that  of  orbit)  containing  a  barbel,  pedicelled,  with  thick,  club-shaped,  trilobate  tip.  On 
each  side  of  this  cavity  are  the  nasal  openings,  which  are  as  in  Halieutichthys. 

The  width  of  the  mouth  is  equal  to  the  distance  between  the  centers  of  the  pupils  of 

the  eyes. 

The  diameter  of  the  orbit  is  contained  as  follows  in  other  dimensions  of  the  body:  In

HalieuUchthys  retieulatm,  Poev,  MS. — Gill,  Proc  Acad.  Nat.  Sci,  Phila.,  1863,  91  (specimen  frcm  Cuba). 

A  species  of  Halieutichthys,  with  cordiform  disc,  which  is  about  as  wide  as  long,  its 
length  more  than  two  thirds  that  of  the  body.  Body  covered  above  with  stout  conical 
spines  with  stellular  liases,  largest,  upon  the  trunk,  upon  which  they  axe  arranged  in  about 
two  irregular  longitudinal  rows  on  each  side  of  the  dorsal;  upon  the  disc  they  are  placed 
above  the  principal  bones  of  the  skeleton,  most  abundant  upon  its  cranial  portion.  A  single 
row  of  stout  spines,  usually  three-pointed,  marks  the  outer  margin  of  the  disc,  a  particularly 
large  one  at  each  outer  angle.  Body  entirely  smooth  below.  Snout  very  short,  obtuse. 
Bridge  over  the  rostral  cavity  covered  in  front  with  a.  three-pointed  spine,  having  on  each 
side  a  simple  spine.  Short,  stout,  simple  spines,  upon  each  supraorbital  margin,  thefrontof 
which  is  immediately  above  and  behind  the  cavity  containing  the  nostrils.  The  vertex 
bears  several  similar  spines.  Many  spines  closely  placed  upon  the  humeral  area.  Numer- 
ous short  tentacles  upon  the  margin  of  the  disc  and  on  the  sides  of  the  trunk.  The  supra- 
oral  cavity  is  elliptical,  small  (horizontal  diameter  two-sevenths  diameter  of  orbit),  contain- 
ing a  well-developed,  club-shaped,  very  perceptible  tentacle.  The  width  of  the  opening  of 
the  anterior  nostril,  which  is  in  a  short  tube,  is  one-half  that  of  the  posterior  nostril,  which 
is  not  tubular.  The  width  of  the  mouth  is  much  less  than  the  distance  between  the  pupils 
and  is  equal  to  the  diameter  of  the  orbit. 

The  diameter  of  the  orbit  is  contained  8J  times  in  distance  from  snout  to  base  of  caudal, 
0  times  in  distance  from  snout  to  origin  of  soft  dorsal,  (i.\  times  in  distance  to  origin  of  anal, 
3  times  in  distance  to  base  of  ventrals,  and  <>  times  in  distance  to  angle  between  pectorals 
and  trunk,  4i{  times  in  distance  from  snout  to  gill  opening,  C  in  greatest  width  of  disc,  and 
nearly  li  in  that  of  trunk.     Width  of  interorbital  area  two-fifths  diameter  of  orbit. 

Dorsal  tin  with  4  or  5  rays,  the  longest  (1st)  equal  to  diameter  of  orbit.  Anal  tin  in- 
serted under  third  ray  of  the  dorsal,  with  1  rays,  the  third  or  longest,  very  slightly  longer 
than  the.  longest  dorsal  ray. 

Ventral  fins  inserted  neatly  under  the  middle  of  the  disc,  with  one  rudimentary  and 
5  dorsal  rays,  increasing  in  length  posteriorly,  the  last  and  longest  contained  5  times  in 
total  length;  distances  between  origins  of  ventrals  <>A  in  total  length. 

Pectorals  with  peduncles  entirely  included  in  common  membrane,  with  blades  far 
back,  horizontal,  lying  close  to  trunk,  composed  of  Hi  rays,  the  middle  or  longest  3§  in  total 
length. 

Caudal  fin,  rounded,  composed  of  9  rays,  the  external  rays,  one  above  and  two  below, 
simple,  the  others  bifid;  length  of  middle  ray  equal  to  that  of  trunk  (measured  from  junc- 
tion of  pectorals  to  base  of  caudal  rays)  and  slightly  exceeding  the  longest  pectoral  ray. 
Length  of  intestine  contained  l{j  times  iu  total  length. 

1  The  rostral  tentacle  in  Halieutichthys  is  by  no  means  obsolete,  though  it  is  said  to  be  by  all  who  have 
discussed  the  genus.

508  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

The  Squalus  uyatus  of  Raflnesque  was  described  from  Sicily,  where  the  fishermen  of 
Palermo  call  it  the  Uyatu;  Centrophorus  uyatus  should  then  be  the  name  of  this  species. 

A  specimen  was  taken  by  Vinciguerra  in  the  Gulf  of  Genoa,  July,  1879,  at  a  depth  of 
GOO  meters  (Crociere  delle  Violante,  1883,  18). 

Centrophorus  foliaceus,  Giiuther  (Challenger  Report,  xxn,  5,  PI.  n,  fig.  a)  was  from 
station  1*32,  off  Inosima,  Japan,  at  a  depth  of  245  fathoms. 

G.  squamulosus,  Gunther  [loc.  tit.,  PI.  n,  fig.  b)  was  from  the  same  locality  as  the 
preceding.

These  captures  show  that  this  shark  is  an  inhabitant  of  the  Mediterranean.  It  will 
probably  be  found  abundant  in  200  to  000  fathoms,  especially  in  the  western  part  of  this  sea.

opinion  upon  the  presence  of  an  adipose  dorsal  (in  in  B.  mollis  and  its  absence  in  B.  ferox. 
It  is  not impossible,  however,  that  the  supposed  absence  of  this  fin  in  the  latter  maybe 
due  to  the  mutilation  of  the  few  specimens  in  existence.

ardson (Scopelus  lumps,  Giinther). 

Scopelus  arcticus,  Liitken,  spolia  atlantica,  scopeluii,  29,  from  Davis  straits,  is  placed  by

512  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

Page  70:  Myctophum  Townsendi,  Eigenmann,  is  pronounced  by  Jordan  and  Evermann 
to  be  closely  allied  to  Lampa.nyctus  alatus,  though  a  distinct  species. 

Page  80:  Lampanyctus  Warmingii  was  found  by  Professor  Warming  in  hit.  32°  C  N., 
Ion.  .;'.»-  28'  W. 

Page  82:  Xotoscopelus.  This  genus  was  first  described  by  Iiisso  under  the  name 
macrostoma,  which  being  virtually  preoccupied  in  entomology  in  the  form  Macrostomus,  we 
unhesitatingly  reject. 

Pages.'>:  The  Macrostoma  augustidens of  Kisso  (Hist.  Nat. Eur. Merit., n, 448), although 
doubtless  of  this  genus,  can  not.  in  our  judgment,  be  identified  at  present  with  any  species. 

Notoscopelus  auerdnus.  This  species  is  very  close.to  the  Scojwlns-  vlongatus  of  Giglioli 
and  Rafaelle,  which  can  not  be  far  away  from  that  of  Costa.  We  are  disposed  to  believe 
with  Bellotti  (Atti  Soc.  Ital.  Soc.  Nat.,  .Milan,  1892,32;  Note alManuale.d' Ittiologia.Prance.se 
del  I  >ott.  Emilio  Moreau,  L6)  that  the  Scopelus  pseudocrocodilus  of  Moreau  (Hist.  Nat.  Poiss. 
France,  Supp.,  1891,  84;  Manuel  d'Ichthyologie  Francaise.  IS!).").  546)  is  identical  with  Costa's 
n.  elongatus. 

Page  88:  Collettia  nocturna.  Jordan  and  Evermann  decide  that  Myctophum  nocturnum, 
Poey  (Memorias,  Hist.  Nat.  Cuba,  n,  426),  probably  belongs  to  the  genus  Collettia. 

Page  89:  Myctophum  crenulare.  Jordan  anil  Evermann  (Proc.  U.  S.  N.  M..  1880,  274), 
from  off  Santa  Barbara,  is  now  placed  by  Jordan  in  the  genus  Tarletonbeania. 

Diaphus  engraulis,  Giinther.  Two  specimens,  identified  by  Alcock  with  this  species, 
were  taken  by  the  Investigator  in  the  Bay  of  Bengal  at  station  115,  iu  188  to  220  fathoms 
(Ann.  and  Mag.  Nat.  Hist.,  August,  1891,  129).  Jordan  and  Evermann  refer  Scopelus 
cceruleus,  Klunzinger,  to  the  genus  Diaphus,  and  make  Myctophum  protoculus,  Gilberl 
(Proc.  U.  S.  N.  M.,  1890,  52),  from  Albatross,  station  3072,  584  fathoms,  off  Washington,  a 
synonym  of  l>ia[)lius  tin  in. 

Page  01:  Rhinoscopelus  runts  was  found  by  Liitken's  correspondents  in  the  Atlantic  in 
the  following  localities:  (1)  Lat.  20  N.,  Ion.  48  -.">o  \Y.:  (2)lat.  34° 50'  S., Ion., 4°  30'  W.;

Scopelus  antarcticus,  Giinther,  is  figured  in  Challenger  Report,  wit,  PI.  i.i.  Fig.  ]).  It 
is  perhaps  a  Rhinoscopelus. 

Page  92:  Scopelus  pyrsobolus,  Alcock  (Scopelus  pyrsobolus,  Alcock,  Ann.  and  Mag. 
Nat.  Hist.,  September,  1890,  218,  PI.  vni,  fig.  3,  outline).  Tins  form  was  obtained  by  the 
Investigator  off  the  Madras  coast  at  a  depth  of  690-920  fathoms.  It  is  impossible  to  tell  to 
what  generic  or  subgeneric  group  it  belongs,  the  most  important  characters  having  been 
obliterated  before  it  was  studied, but  it  would  seem  to  resemble  in  a  general  way  Lampadena.

Vaillant,  Exp.  Sci.  Trav.  et  Tal.,  tin.  PI.  i\,  figs.  2,  2a,  2b. 

According  to  President  Jordan,  Stenobrachius  of  Eigeumann  is  a  synonym  of  Nanno- 
brachium, though  having  the  dorsal  ending  over  the  third  or  fourth  anal  ray,  and  A',  leucop- 
sarum  is  a  Nannobrachium  as  well  as  .V.  mexicanum,  Gilbert  (Proc.  V.  S.  Nat.  Mus.,  1890, 
51),  from  off  the  coast  of  southern  California,  and  X.  regale,  Gilbert  (Proc.  U.  S.  Nat. 
Mus.,  1891,  541),  from  the  Santa  Barbara  Channel,  California. 

Scopdenyiik  tristis,  Alcock  (111.  Zool.  Investigator,  Fishes,  P1.YII,  tig.  7,  Calcutta,  1892) 
is  not  a  member  of  the  Myctophidce,  hut  apparently  has  affinities  with  the  .1  ulopidce. 

Page  94:  Myctophum  leucopsarum,  Eigenmann  (Proc.  Cal.  Acad.  Sci.,  1890,  5),  taken  off 
Point  Loina,  Lower  California,  in  stomachs  of  Sebastodes,  is  pronounced  by  Jordan,  who  has 
seen  this  type,  to  belong  to  Nannobrachium.  Other  species  of  this  genus  are  that  described 
by  (Gilbert  under  the  name  Myctophum  nannochir,  from  Albatross  station  3072,  off  the  coast 
of  Washington,  and  since  found  at  various  points,  from  the  Santa  Barbara  Islands  to  Alaska.

VINCIGUERRIA,  Jordan  &  Evermann. 

This  genus  is  close  to  Maurolicus,  from  which  it  differs,  according  to  Liitken,  chiefly 
in  the  character  of  its  luminous  spots  which  are  pearl-like  and  placed  on  black  globular 
bodies.  Anal  short,  of  14  rays.  (Named  for  Dr.  Decio  Vinciguerra,  director  of  the  Acquario

This  genus  is  close  to  Maurolicus  but  with  the  dorsal  fin  farther  back,  opposite  anal,  its 
Iirst  tay  nearly  over  front  of  anal.  Photophores  above  anal  gathered  in  about  live  clusters,

Page  104:  After  Photichthys  add:  The  species  described  by  Johnson  under  the  name 
Gonostoma  maderense  (Proc.  Zool.  Soc,  1S90,  458)  does  not  belong  to  the  genus  Gono.stoma  as 
limited  by  us,  although  apparently  a  member  of  the  family  Gonostomidce.  Its  relations  are 
most  nearly  with  Photichthys,  having  as  it  does  the  dorsal  flu  placed  in  the  middle  of  the 
back  over  the  space  between  the  ventral  and  the  anal.  It  is,  however,  distinguished  from 
Photichthys  by  the  absence  of  the  adipose  tin  and  scales  upon  the  back,  and  by  the  pres- 
ence of  scales  upon  the  cheek  and  also  by  the  absence  of  fangs  upon  the  vomer,  and  the 
presence  of  a  double  row  of  teeth  in  the  anterior  portion  of  the  lower  jaw. 


APPENDIX.  5  1  5 

Bather  than  assign  an  Atlantic  species  to  a  genus  only  known  from  the  South  Pacific 
it  seems  justifiable  to  provisionally  form  a  new  genus  for  its  reception,  it  being  in  our  judg- 
ment safer  to  overestimate  diagnostic  characters  which  are  supposed  to  exist  rather  than 
to  undervalue  them  and  withdraw  attention  from  them  by  the  opposite  course. 

We  therefore  propose  for  this  form  the  generic  name  Manducus,  characterized  as  fol 
lows:  Body  oblong,  compressed,  covered  with  scales  except  upon  the  top  of  the  head  and 
upon  the  ridge  of  the  hack,  which  is  rugosely  warted;  two  rows  of  spots  on  each  sideof 
the  belly  close  to  the  ventral  line.  Head  elongate,  conical,  much  compressed,  with  thin 
bones:  the  cheeks  covered  with  large  scales.  Opercular  hones  thin,  the  mouth  anil  gill 
openings  very  wide  Ohderjawfor  the  most  part  included,  armed  with  a  single  row  of 
sharp  conical  teeth  with  small  ones  between  them  and  a  double  row  of  eight  smaller,  but 
similar  ones  in  front.  Upper  jaw  with  a  single  row  of  teeth  in  front  similar  to  those  in  the 
lower  jaw.  followed  on  either  side  by  a  lew  very  long  teeth  with  others  smaller  behind. 
Vomer  \\  ith  a  lew  teeth;  a  row  of  minute  sharp  teeth  on  the  palatines,  and  a  row  of  teeth 
on  the  entopterygoids as  well  as  a  small  similar  patch  on  the  upper  side  of  the  tongue.  Eye 
moderate.  Dorsal  in  the  middle  of  the  back  over  the  space  between  the  ventral  and  the 
anal.  Pectoral  and  ventral  well  developed,  the  latter  narrow  and  shorter  than  the  pec- 
toral.    Anal  lower  than  dorsal  with  longer  base.     Lateral  line  much  as  in  Oonostoma. 

MANDUCUS  MADERENSIS  (Johnson). 

Diagnosis:  A  fish  having  the  body  elongate,  compressed;  its  height  is  included  i;1, 
times  in  its  length  without  the  caudal;  the  length  of  the  head  ■"">'  times  in  the  same  distance. 
The  top  of  the  head  is  scaleless,  armed  with  two  low  converging  ridges  which  meet  in  front 
of  the  orbits  ("hecks  with  large  scales;  profile  rather  steep  and  snout  short.  The  eye, 
which  is  round,  does  not  reach  the  profile;  its  diameter  is  included  about  5  times  in  the 
length  of  the  head,  its  distance  from  the  snout  is  rather  more  than  its  own  diameter,  and 
from  the  jaw  rather  less. 

The  lateral  line  begins  near  the  edge  of  the  operele,  ^  of  the  height  from  the  outline  of 
the  back,  and  following  gently  until  it  reaches  the  middle  of  the  height  under  the  dorsal, 
it  then  runs  straight  to  the  base  of  the  caudal.  Two  rows  of  photophores,  which  are  silvery 
or  pale  steel  blue  in  color,  are  closely  set  low  down  on  each  side  of  the  belly.  The  upper 
row,  on  which  between  tilt  and  70  spots  may  be  counted,  begins  at  the  throat  and  is  con- 
tinued to  the  base  of  the  caudal,  and  the  lower  row  runs  along  the  isthmus  between  the  gill 
openings  and  likewise  extends  to  the  caudal.  »

ARCTOZENUS,  Gill. 

Arctozenus,  Gill,  l'roc.  Ac.  Nat.  Sci.  l'hila.,  1864,  188. 

Head  elongate,  conical,  the  snout  attenuate,  the  jaws  straight,  the  lower  mostly  cov- 
ered by  the  upper;  teeth  of  lower  jaw  anteriorly  slender,  recurved,  and  distant;  posteriorly 
small,  acute,  and  close  together.  This  genus  is  closely  related  to  Sudis,  from  which  it  differs 
mainly  in  the  absence  of  fang-like  teeth.  From  Paralepis  it  differs  in  the  position  of  the 
ventral  tins,  which  are  entirely  behind  the  dorsal.  The  known  species  belong  to  the  deep 
waters  of  Arctic  America ;  long,  slender  tishes  suggesting  the  Barracuda  in  outline.  («,<«-:, 
northern;  Zivos,  strange.) 

«.    Teeth  comparatively  strung;  Atlantic  species, A.   borealis.

A.  coruscans  was  described  by  Jordan  and  Gilbert,  in  1880  (Proc.  IT.  S.  N.  M.,  411),  from 
off  Port  Townsend,  Washington. 

Page  120:  Paralepis  intermedins,  Poey,  is  referred  to  Sudis. 

Odontostomus  atratus,  Alcock  (Journ.  Asiatic  Soc.  of  Bengal,  lxh,  Part  n,  No.  4, 1883, 
p.  14,  PI.  ix.  fig.  1),  was  obtained  from  128  fathoms  in  the  Bay  of  Bengal. 

Page  128:  Polyipnus  spinosus.  The  locality  of  the  specimen  assigned  by  Alcock  to  this 
species  was  Investigator  station  115,  and  the  range  of  depth  was  108  to  220  fathoms — not 
210.  as  stated  in  the  text. 

Tdiaeanthus  antrostomus,  Gilbert,  was  obtained  by  the  Albatross  in  (503  fathoms  at 
station  29S0,  off  the  coast  of  southern  California  (Proc.  U.  S.  N.  M.,  xm,  1800,  54).

This  species,  represented  by  a  single  female,  about  15  inches  long,  with  gravid  ovaries, 
taken  by  the  Investigator  at  station  122,  Laccadive  Sea,  805  to  880  fathoms,  has  the  scales 
of  the  lateral  line  but  little  larger  than  those  of  the  rest  of  the  body,  and  probably  belongs 
to  the  restricted  genus  Halosaurus.

gator  in  the  Laccadive  Sea,  station  120,  1,37b  fathoms,  and  in  the  Gulf  of  Manaar,  station 
12S,  102  fathoms.  He  suggests  that  this  species  is  perhaps  identical  with  that  described 
by  Vaillant  under  the  name  Nemichthys  in/ans;  in  other  words,  the  species  discussed  by 
us  under  the  name  of  Serrivomer  Richardii  (see  p.  155).  This  opinion  is.  of  course,  simply 
by  way  of  suggestion. 

The  form  referred  by  Wood-Mason  to  the  genus  (larialicep.s.  under  the  name  G.  tamiola, 
is  referred  by  Alcock  to  the  genus  Nettastoma.  After  a  study  of  numerous  sexually  imma- 
ture males  and  females,  nearly  2  feet   in  length,  and  several  young  ones,  from  Investigator

station  120,  Bay  of  Bengal,  120  to  76  fathoms,  Alcock  states  that  the  species  was  originally 
described  from  immature  individuals,  and  was  included  with  Gavialiceps  microps  in  a  new 
genus.  The  investigation  of  full-grown  individuals  shows  that  this  species  has  no  place  in 
the  genus  Gavialieeps,  which  is  a  true  Nemichthyine  form  without  tins,  but  that  it  ought  to 
be  rauked  with  JSTettastoma  (Alcock,  Ann.  and  Mag.  Nat.  Hist.,  1891,  136).

The  specimen  described  by  Dr.  Hector  was  only  2.7  inches  long,  and  was  obtained  nil'

Hoplostethus  mediterraneus.  The  range  of  tins  species,  not  hitherto  known  north  of 
Madeira,  has  been  extended  to  the  coast  of  Greal  Britain  by  the  Rev.  .Mr.  Green,  who 
obtained  a  specimen  in  the  summer  of  188!)  oil  the  southwest  coast  of  Ireland  (Giinther, 
Ann.  and  Mag.  Nat.  Hist..  December,  1889,  417). 

The  range  of  this  form  in  the  Mediterranean  seems  to  be  limited  on  the  east  by  Malta 
(Gulia,  Tentam.,  Ichth.  Melitens.,  1861,22).  It  was  recorded  by  Guichenot  and  Bonrgeol 
from  Algeria,  and  is  also  known  from  the  (lull'  of  Naples  [Costa;  and  the  Galf  of  Palermo 
(Doederlein),  who  records  it  also  from  Messina,  where  it  is  called  "Bulicaru." 

Its  range  in  the  western  Atlantic  is  from  11 :  13'  to  39'  .">()'  X.  hit.;  in  the  eastern 
Atlantic  from  36°  to  50°. 

A  specimen  was  taken  in  the  Bay  of  Bengal  at  Investigator  station  L62,  at  a  depth  of 
145 to 250 fathoms. — Alcoek,  Journ.  Asiatic  Soc.  of  Bengal,  iaiu.  Part  it,  No.  L',  1894,  p.  2. 

We  are  disposed  to  recognize  the  Hoplostethus  japonicus  of  Hilgeudorf  as  a  distinct 
Species,  until  the  differences  recorded  by  Hilgeudorf  and  Giinther  can  be  studied  from  a 
larger  series  of  specimens. 

Page  195:  Jordan  and  Evermann  propose  the  new  generic  name  Escolar  for  Thyrsi-

Pise.,  <  lubens,  1875,  p.  74),  is  of  the  same  species.  Since  this  was  described  from  a  fragment, 
we  have  not  taken  it  into  consideration  in  our  studies.

abundance  off  the  coast  of  Portugal,  where  it  is  taken  in  the  open  sea  in  March  and  April 
(Peixesde  Portugal,  1880,  16). 

The  specilie  identity  of  the  fish  found  at  St.  Lucas  by  Xantus  is  so  doubtful  that  we 
prefer  to  refer  to  it  as  /,.  Xantusi,  new  specific  name.

520  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

This  genus,  dedicated  by  Jordan  and  Bvermann  to  Dr.  Leonhard  Stejneger,  curator  of 
reptiles  in  the  U.  S.  National  Museum,  is,  according  to  Jordan  and  Evermanu,  closely 
allied  to  Grammicolepii  and  Psenes,  and  is  placed  by  them  provisionally  in  the  family 
Bramidw,  although  its  relations  are  not  definitely  determined. 

Having  been  found  in  the  stomach  of  a  Red  Snapper,  which  inhabits  considerable 
depths, it  is  provisionally  placed  among  deep-sea  fishes.  The  fact  of  its  never  having  been 
found  in  the  surface  faunas  of  the  Gulf  of  Mexico  gives  additional  reason  for  supposing 
that  it  is  an  inhabitant  of  the  deep  regions. 

STE1NEGERIA  RUBESCENS,  Jordan  and  Evermann. 

Steinegeria  rubescens,  Jordan  and  Evermanu,  Proc.  U.  S.  Nat.  Mns.,  1886, 467. 

Body  ovate,  considerably  compressed,  the  greatest  thickness  a  little  less  than  half  length 
of  head.  Anterior  of  profile  from  tip  of  snout  to  base  of  dorsal  nearly  straight.  Outline 
of  belly  prominent,  the  axis  of  body  being  rather  nearer  dorsal  than  ventral  outline.  Breast 
and  belly  not  carinate. 

The  head  is  but  little  longer  than  deep,  its  upper  surface  flattish,  the  bones  not  very 
firm;  its  length  contained  2jj  times  in  the  total  length  (34  with  caudal):  the  depth  twice 
(2^  with  caudal).  Interorbital  space  nearly  fiat,  with  two  ridges,  about  as  broad  as  eye, 
which  is  3£  in  head.  Preorbital  very  narrow,  somewhat  cavernous,  its  edge  sharply  den- 
tate; snout  short,  5 in  head. 

Mouth  very  oblique,  the  lower  jaw  strongly  projecting,  the  broad  maxillary  reaching 
to  below  middle  of  eye,  its  length  half  that  of  the  head.  Each  jaw  with  a  band  of  small 
cardiform  teeth,  those  in  front  largest,  especially  in  the  lower  jaw,  but  all  of  them  small. 
A  band  of  villiform  teeth  on  each  palatine  bone,  but  uoue  on  the  vomer;  premaxillaries 
protractile.     Lower  jaw  with  conspicuous  pores 

Preopercle  forming  a  nearly  even  curve,  without  distinct  angle.  Ascending  limb  of 
preopercle  very  finely  serrulate,  with  sonic  four  or  five  coarser  teeth  about  the  angle.  Other 
opercular  bones  very  thin,  with  entire  edges.  ( 'heeks,  opercles,  maxillary,  and  top  of  head 
closely  covered  with  scales  similar  to  those  on  rest  of  body,  but  a  little  smaller. 

Gill-rakers  rather  short  and  wide  apart,  *  or  '■•  developed  on  the  lower  part  of  the  arch, 
the  longest  about  one-third  length  of  eye. 

Body  closely  covered  with  membranous  scales  which  are  closely  imbricated,  deeper  than 
long,  each  with  a  distinct  median  keel  besides  which  are  some  smaller  radiating  ridges, 
especially  on  the  scales  of  the  sides  of  the  body.  These  ridges  on  the  scales  give  the  body 
a  rough  appearance,  although  they  are  not  spiugerous.  The  keels  on  the  scales  form  con- 
tinuous ridges,  giving  the  whole  body  a  striated  appearance.  Scales  largest  on  middle  of 
sides,  becoming  smaller  on  back  and  on  belly.  Xo  distinct  lateral  line.  Fins  with  few- 
scales  or  none. 

Dorsal  spines  very  slender  and  flexible,  some  of  them  ending  in  filaments  (all  more  or 
less  mutilated  in  typical  example).  Soft  rays  separated  from  spines  by  a  deep  notch 
extending  nearly  to  base  of  fin.  Soft  dorsal  elevated,  the  longest  rays  about  14,  in  head. 
Caudal  lunate,  its  peduncle  very  short  and  slender.  Anal  fin  high,  its  spines  short  and 
slender,  the  longest  ray  1£  in  head.  No  free  anal  spines.  Ventrals  inserted  before  pec 
torals,  their  length  1?  in  head.  Ventrals  not  depressible  into  a  fissure  of  the  abdomen. 
Pectorals  li  in  head.     Vent  well  behind  ventrals. 

Color  in  life  salmon  red,  rather  bright  and  nearly  uniform,  darker  on  back,  silvery 
under  the  chin.  Fins  all  salmon,  with  black  areas  toward  base  on  both  dorsals  and  anal. 
Ventrals  largely  black.    Lining  of  opercles  pale. 

Eadial  formula:  D.  XI-I,  18;  A*  II,  20;  V.  1,  5.     Scales  ca.  50-2ti. 
A  siugle  specimen  (Cat.  Nb."37991,  U.  S.  X.  M.),  5  inches  in  length,  in  fair  condition,

A  genus  found  in  the.  Eastern  seas  and  represented  by  four  species,  one  from  the 
Indian  Ocean,  Borneo,  and  China,  one  from  Japan,  and  one  from  Celebes,  besides  the 
hemibathybial  forms  from  the  Bay  of  Bengal  mentioned  below.

1'age  266:  Coitus  bathybii,  Giinther,  Challeng';r  Report,  xxn,62,  PL  \,  Fig.  C.  A  sin- 
gle specimen,  2J  inches  long,  was  obtained  by  the  Challenger  at  station  235,  south  of  Yeddo, 
Japan,  in  565  fathoms. 

'•It  may  appear  matter  tor  surprise,"  says  Giinther,  "to  find  a  species  of  Coitus  at  so 
great  a  depth  as  560  fathoms,  and  at  first  sight  it  did  not  seem  to  me  improbable  that 
the  specimen  accidentally  entered  the  mouth  of  the  dredge  whilst  it  was  near  the  surface. 
However,  on  further  consideration  these  doubts  disappeared,  as  it  is  not  very  likely  that  a 
fish  living  habitually  at  the  bottom,  as  a  Cottus  must  do,  should  be  found  floating  far  from 
land;  moreover  the  muciferous  system  is  developed  to  an  extraordinary  degree,  much  more 
so  than  in  the  littoral  species  of  the  genus." 

A  species  very  nearly  related  to  c.  bathybii  was  obtained  by  the  Albatross  in  the.  depths 
off  the  Alaskan  coast.     It  has  not  yet  been  described.

the  integumenl  does  not  allow  us  to  determine  the  point  where  the  maxillary  terminates. 
Teeth  very  nearly  conical,  pointing  backward,  in  both  jaws;  teeth  also  upon  the  vomer  and 
palatines.  A  single  nostril  is  distinguishable,  tubular,  and  placed  far  forward  on  the 
border  of  the  lip,  so  thai  at  ftrsl  sight  it  might  be  mistaken  for  one  of  the  mucous  openings, 
of  which  there  are  about  six  on  the  upper  jaw.  and  tour  or  live  in  each  branch  of  the  low  er 
jaw.  Eye  superior,  scarcely  visible  even  in  the  fresh  specimen,  being  hidden  under  the 
skin:  dia  meter  scarcely  one  ninth  of  the  length  of  the  head  and  one -third  that  of  the  muzzle 
equaling  the  width  of  the  interorbital  space.  The  branchial  opening  is  very  large,  though 
the  branchiostegal  membrane  does  not  adhere  to  the  isthmus  but  by  a  very  slight  attach- 
ment.    The  skin  of  the  head  is  naked. 

The  vent  is  found  a  little  in  advance  of  a  point  which  is  two-sevenths  of  the  distance 
from  the  tip  of  the  snout  to  the  tip  of  the  tail.  Scales,  resembling  pale  spots,  are  very  dis- 
tinct on  the  posterior  part  of  the  body,  and  in  the  forward  part  of  the  body  they  may  be 
seen  clearly  on  the  ventral  portion  of  the  animal  after  it  has  been  kept  in  alcohol.  A  lateral 
line,  scarcely  distinguishable,  is  anteriorly  nearly  in  the  middle  of  the  height,  but  poste 
riorly  descends  close  to  the  ventral  line. 

Dorsals  placed  far  back,  commencing  at  the  end  of  the  anterior  fourth  of  the  length;  the 
origin  of  the  anal  still  farther  back.  These  fins  are  low,  exactly  similar,  coalescing  with 
the  caudal.  Pectoral  large,  enveloped  in  a  thick  integument;  its  extremity  does  not  reach 
to  the'vertical  from  the  origin  of  the  dorsal.  The  ventrals  are  represented  each  by  a  single 
ray  apparently,  although  it  is  probable  that,  in  reality,  there  are  several  united  in  the  same 
cutaneous  envelope. 

Color,  in  fresh  condition,  white,  slightly  bluish;  with  the  head,  and  the  dorsal  and 
ventral  lines  close  to  the  base  of  the  corresponding  tins,  a  clear  blue  indigo;  abdomen, 
dark  ;  pectorals,  ventrals,  and  the  margin  of  the  vertical  tins,  sepia  brown;  iris,  bluish. 

Two  specimens  were  obtained  by  the  French  explorers  in  the  North  Atlantic  at  station 
133,  in  .'i,'.>7.")  meters. 

Lycenchelys  porifer,  Cilbert  (Proc.  U.  S.  N.  M.,  xnr,  1890,  104).  A  single  specimen,  12

(  II ALINURA  MEDITEEEANEA,  Giglioli.     (Figure  345A.) 

Only  two  specimens  known,  preserved  in  the  central  collection  of  Italian  vcrtebrata  in 
the  Royal  Zoological  Museum,  Florence;  ichthyological  catalogues  Xos.  2016,2017.  They 
were  both  collected  by  me  during  the  first  deep-sea  exploration  of  the  Mediterranean  by 
the  Italian  man-of-war  steamer  Washington  off  the  west  coast  of  the  island  of  Sardinia  with 
the  trawl,  at  station  x  (hit.  41°  23'  48"  NT.,  Ion.  7°  8'  54"  E.,  depth  2,904  meters)  and  station 
xi  ilat.  II  18  42"  N.,  Ion.  6°  54'  2"  E.,  depth  2,805  meters),  on  the  10th  of  August,  1881. 
Tiny  have  hitherto  been  mentioned  with  doubt  as  referable  to  Coryphamoides  serratus 
(Lowe),  a  species  insufficiently  described,  of  which  the  type  specimen  is  lost,  none  having 
been  found  since  to  fit  the  incomplete  diagnosis  given  by  Lowe  (Proc.  Zool.  Soc.  London, 
1843,  91). 

These  two  specimens  are  very  similar  and  apparently  adult;  both  appear  to  be  males, 
but  the  genital  organs  are  immature.  They  arc  both  almost  denuded  of  scales.  These  are 
evidently  very  deciduous,  smooth,  very  slightly  fluted  longitudinally,  cycloid;  rather  large; 
some  show  slightly  tine  radiating  stria'.  When  fresh  the  color  of  these  two  specimens  was 
a  light  pink  or  flesh  color,  the  head  and  belly  strongly  tinted  with  violaceous  black;  the  latter 
on  account  of  the  intense  black  peritoneal  lining  of  the  visceral  cavity,  the  former  owing  to 
the  deep  black  of  the  inside  of  the  mouth  and  branchial  chambers;  the  branchiostegal mem- 
branes are  also  deep  black.  Fins  colorless.  Length  of  the  first  specimen,  215  millimeters; 
of  the  second. 235  millimeters.  The  greatest  height  of  the  body  is  from  the  ventrals  to  the 
first  dorsal;  it  is  less  than  the  length  of  the  head,  and  contained  about  5 A  times  in  the 
total  length.  That  of  the  head  being  contained  about  4§  in  the  total.  The  eye  is  small,  its 
transverse  diameter  being  contained  about  li  in  the  length  of  the  snout;  the  width  of  the 
interorbital  area  above  is  equal  to  the  length  of  the  snout.  The  fore  part  of  the  bodj 
between  the  eyes  and  the  first  dorsal  is  remarkably  gibbous. 

The  snout  is  broad,  truncate,  not  much  produced,  tricuspidate;  three  ridges  running 
along  its  wide  upper  surface,  median  one  gibbous;  the  suboeular  ridges  are  less  marked, 
and  the  suborbital  one  is  not  joined  to  the  angle  of  the  preoperculum. 

Mouth  large,  lateral,  subtei  minal;  intermaxillary  heterodont  with  outer  series  of 
strong  widely  set  teeth  and  an  inner  villifonn  baud;  mandibulary  teeth  uuiserial,  large. 


534  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

Lower  jaw  slightly  shorter.  No  teeth  on  vomer  and  palatines.  Tongue  voluminous, 
smooth,  with  a  band  of  singular  spheroidal  papillae  down  its  middle.  Cleft  of  the  mouth 
extending  to  vertical  of  hind  margin  of  eye.  No  pores.  Branchial  apertures  wide;  small 
pseudobranchiae.  Gill-rakers  spiny,  stout,  in  double  series  on  the  anterior  arch.  Branchi- 
ostegal  membranes  free  from  the  isthmus. 

Barbel  slender,  longer  than  the  transverse  diameter  of  the  eye.  Preoperculum  with 
hinder  margin  nearly  straight,  rounded  below  and  very  slightly  crenulated. 

The  first  dorsal  fin  commences  exactly  above  the  insertion  of  the  pectorals;  its  first 
spine  is  very  short,  the  second  ray  very  robust,  longest,  regularly  serrated  in  its  front  up 
to  its  extremity,  which  is  prolonged  in  a  filament;  its  length  is  equal  to  the  distance  of 
the  dorsal  from  the  eye.  The  second  dorsal  commences  above  the  sixth  anal  ray;  its  rays 
are  very  low,  especially  in  the  first  third  of  its  length.  The  anal  commences  immediately 
behind  the  anal  aperture,  it  is  at  least  five  times  as  high  as  the  second  dorsal,  it  gradually 
becomes  lower  toward  the  end  of  the  caudal  region,  where  it  is  nearly  subequal  to  the  end 
of  the  second  dorsal,  but  always  higher.  I  can  make  out  in  my  specimens  a  caudal,  con- 
tinuous with  the  dorsal  and  anal,  but  distinguished  by  its  longer  rays.  The  pectorals  are 
in  a  bad  condition  in  both  specimens,  but  the  upper  ray  appears  to  be  slightly  elongated. 
The  veutrals  are  inserted  below  the  pectorals,  but  distinctly  in  advance;  their  outer  ray 
is  filamentous,  stouter,  and  greatly  prolonged,  reaching  to  the  twentieth  anal  ray. 

Budial  formula:  I  D.  |;  II  D.  110  circa;  A.  120  circa;  C.  3;  P.  20;  V.  j  ;  Br.  VI. 

I  may  add  that  I  have  taken  extra  care  in  making  out  the  radial  formula,  which  is  not 
an  easy  undertaking  in  fishes  of  this  sort.  Except  the  second  dorsal  and  anal  in  which 
the  given  number  of  the  rays  is  approximated,  I  am  quite  certain  about  the  rest. 

Chalinura  mediterranea  is  evidently  allied  to  C.  Simula,  Goode  and  Bean,  and  to  C. 
leptolepis  (Giinth.),  but  has  a  shorter  and  more  carina tc  snout  thau  either.  In  this  it 
approaches  more  O.femandeziana  (Giinth.),  whilst  its  veutrals  witli  a  larger  number  of  rays 
bring  it  near  C.  Murrayi  (Giinth.).  But  it  is  withal  sufficiently  different  to  warrant  its 
specific  distinction.  I  have  to  thank  my  friend.  Prof.  G.  Brown  Goode,  for  having  specially 
railed  my  attention  as  to  the  Letter  determination  of  these  two  specimens,  which  I  had  left 
up  to  the  present  under  the  name  (with  query)  of  Goryphcenoides  serratus  (Lowe),*  a  species 
which  must  be  canceled  from  the  "Systema  Piscium." 

I  had  been  hitherto  under  the  impression  that  Krohnius  filamentosus,  Cocco,  might  be 
the  larval  form  of  the  fish  I  have  now  named  Chalinura  mediterranea;  but  a  careful  exam- 
ination has  now  shown  me  that  that  singular  larval  form,  evidently  a  Macrurid,  although 
possessing  the  shape  and  some  of  the  indications  of  characters  pertaining  to  Chalinura,h&s 
a  smooth  second  ray  in  its  first  dorsal.  The  doubt  must  yet  remain,  for  I  do  not  think  it 
likely  that  it  should  prove  to  be  the  larva  of  my  Hymenocephalus  italicus.

The  height  of  the  body  is  two-fifths  of  the  total  length  (without  caudal),  the  length  of 
the  head  nearly  one-third;  scales  rather  small,  with  the  posterior  margin  ciliated,  truncated 
or  rounded,  covering  nearly  the  whole  head,  the  interorbital  space  and  maxillary  included: 
interorbital  space  extremely  narrow;  the  diameter  of  the  eye  is  oue-third  the  length  of  the 
head.  Lateral  line  with  a  sub-semicircular  curve  above  the  pectoral  fin.  Lower  jaw  prom- 
inent: maxillary  nearly  one-half  the  length  of  the  head.  The  teeth  in  the  jaws  form  nar- 
row bands;  vomerine  teeth  in  small  number  (two  or  three),  implanted  somewhat  behind  the 
front  margin  of  the  vomer.  The  lower  eye  a  little  in  advance  of  the  upper.  The  dorsal 
I'm  terminates  at  a  distance  from  the  caudal,  which  is  somewhat  less  than  the  depth  of  the 
free  portion  of  the  tail;  its  longest  rays  are  at  the  commencement  of  the  posterior  third  of 
the  fin,  where  they  are  two  fifths  of  the  length  of  the  head,  and  rather  shorter  than  the 
pectoral.  No  spine  before  the  anal.  Body  very  light  colored,  without  spots;  two  large 
rounded  deep  black  spots  occupy  the  posterior  portion  of  the  dorsal  and  anal  (ins  (Qiinther). 

Radial  formula:  D.  80-81;  A.  63-6.".;  L.  hit.  85. 

This  species  was  added  to  the  British  fauna  by  the  discovery  in  L889  of  several  speci- 
mens off  the  southwest  coast  of  Ireland  at  150  to  315  fathoms,  the  largest  being  14  inches 
in  length,  the  smallest  about  half  that  size. 

'•This  species."  writes  Dr.  Giinther,  "originally  discovered  in  the  Mediterranean,  was, 
probably  owing  to  the  small  size  or  condition  of  the  specimens,  inaccurately  described  anil 
figured  by  Risso,  Bonaparte,  and  Canestrini.  Tin1  scales  were  represented  much  too  large, 
and  the  notes  on  the  dentition  were  vague.  Hence  it  was  referred  by  myself  to  the  genus 
Arnuylostsus  at  a  time  when  no  specimens  were  available  for  examination  (Pish,  iv,  416),  but 


536  DEEP-SEA    FISHES    OF    THE    ATLANTIC    BASIN. 

there  was  sufficient  evidence  of  its  being-  a  very  distinct  species  from  any  of  the  tint  fishes 
known  to  inhabit  the  British  Seas.  Nevertheless,  we  find  it  in  the  'Fishes  of  Great  Britain 
by  F.  Day  (who  seems  to  have  followed  Giglioli)  relegated  to  the  synonymy  of  Rhombus' 
■megastoma,  an  error  which,  in  1S83,  was  corrected  by  Yiuciguerra,  and  in  1887  by  Kolamba- 
tovic,  both  of  whom  clearly  pointed  out  the  distinctive  characters  of  these  two  species.'' 

"  Rhombus  Boscil  may  be  recognized  at  the  first  glance  by  its  enormous  eyes,  which  are 
much  larger  than  in  Rhombus  megastoma,  as  maybe  seen  from  the  following  measurements:

"Rhombus  megastoma  never  has  the  large  black  spots  on  the  dorsal  and  anal  fins  which 
are  so  conspicuous  a  feature  in  R.  Boscii,  although  they  may  also  disappear  in  specimens  of 
the  latter  species  if  they  have  been  allowed  to  get  stale  before  they  are  placed  in  spirits" 
(Giinther). 

This  species  was  added  to  the  British  fauna  by  the  discovery  in  1889  by  the  Bev.  Mr. 
Green,  of  several  specimens  off  the  southwest  coast  of  Ireland,  at  150  and  315  fathoms 
(Giinther,  Ann.  and  Mag.  Nat.  Hist.,  December,  1SS9,  418). 

Amoglossus  Grohmanni,  Bonaparte  (Pleuronectes  Grohmanni,  Yaillant,  Exp.  Sci.  Trav. 
et  Tal.,  1SS).  The  French  explorers  obtained  specimens  of  this  well-known  Mediterranean 
form  off  the  coast  of  Morocco  in  112  and  120  meters,  off  Spain  in  106  meters,  off  Soudan 
in  102  to  175  meters,  and  about  the  Cape  Verde  Islands  in  75  to  90  meters.

SOLE  V  GREEM,  Giinther. 

Solea  Greeni,  Glxtiikr,  Aim.  ami  Mag.  Xat.  Hist.,  December,  1889,  4 lit. 

This  species  is  very  elongate,  its  greatest  width  being  one-third  of  the  total  length 
(without  caudal);  the  length  of  the  head  is  contained  five  and  a  half  times  in  the  total 
length.  The  shape  of  the  head  resembles  very  much  that  of  the  common  sole.  The  eyes 
are  of  medium  size,  about  as  long  as  the  snout  and  one-fifth  of  the  length  of  the  head;  the 
width  of  the  interorbital  space  equals  the  vertical  diameter  of  the  eye.  None  of  the  nos- 
trils dilated,  that  in  front  of  the  lower  eye  being  prolonged  into  a  short  tube;  the  vertical 
fins  are  rather  low  and  covered  with  scales.  The  right  pectoral  very  small,  about  as  long- 
as  the  eye;  the  left  pectoral  is  reduced  to  a  minute  ray.  The  ventrals,  also,  are  small,  but 
the  extremities  of  their  middle  rays  extend  backwards  to  the  anal  tin.  The  dorsal  and 
anal  terminate  immediately  in  front  of  the  caudal.  Scales  of  both  sides  ctenoid,  more  so 
on  the  colored  than  on  the  blind  side.     Goloration  uniform  gray  (Giinther). 

Radial  formula:  D.  SI;  A.  65;   P.  dextr.  5;  P.  sin.  1;  L.  lat.  144. 

This  species  is  distinguished  by  characters  which  bring  it  near  to  Solea  vulgaris  as  well 
as  to  Solea  variegata.  From  the  former  it  is  separated  by  the  rudimentary  structure  of  its 
pectoral  fins,  from  the  latter  by  the  number  of  its  fin  rays,  by  its  much  smaller  scales,  and 
by  its  coloration.  Unfortunately  only  one  specimen  was  obtained,  off  the  southwest  coast 
of  Ireland,  nearly  6  inches  long,  at  a  depth  of  150  fathoms.  It  is  in  a  perfect  state  of 
preservation  (Giinther.)

A  genus  resembling  Onchocephalus  (=Malthe),  but  having  only  two  gills  on  each  side 
instead  of  two  and  a  half,  represented  by  the  single  species,  Malthopsis  luteins  (Alcock,  h><:

This  work  (Special  Bulletin  No.  2)  is  one  of  a  series  of  papers  intended  to  illustrate  tlie 
collections  belonging  to,  or  placed  in  charge  of,  the  Smithsonian  Institution,  and  deposited 
in  the  United  States  National  Museum. 

The  publications  of  the  National  Museum  consist  of  two  series — the  Bulletin  and  the 
Proceedings.  A  small  edition  of  each  paper  in  the  Proceedings  is  distributed  in  pamphlet 
form  to  specialists  in  advance  of  the  publication  of  the  bound  volume.  The  Bulletin  is 
issued  only  in  volumes.  Most  of  the  volumes  hitherto  published  have  been  octavos,  but  a 
quarto  form  has  been  adopted  for  works  of  the  size  and  character  of  the  present  Bulletin, 
this  being  No.  2  in  the  quarto  series. 

The  Bulletin  of  the  United  States  National  Museum,  the  publication  of  which  was 
commenced  in  1S75,  consists  of  elaborate  papers  based  upon  the  collections  of  the  Museum, 
reports  of  expeditions,  etc.  The  Proceedings  are  intended  to  facilitate  the  prompt  publi- 
cation of  freshly  acquired  facts  relating  to  biology,  anthropology,  and  geology,  descriptions 
of  restricted  groups  of  animals  and  plants,  discussions  of  particular  questions  relative  to 
the  synonymy  of  species,  and  the  diaries  of  minor  expeditions. 

Other  papers  of  more  general  popular  interest  are  printed  in  the  appendix  to  the 
annual  report. 

Papers  intended  for  publication  in  the  Proceedings  and  Bulletin  of  the  United  States 
National  Museum  are  referred  to  the  advisory  committee  on  publications,  composed  as 
follows:  Frederick  W.  True  (chairman),  It.  Edward'Earll  (editor),  James  E.Benedict,  Otis 
T.  Mason,  Leonhard  Stejueger,  and  Lester  E.  Ward.
