CATALOGUE  OF  THE  FRESH-WATER  FISHES  OF 
TROPICAL  AND  SOUTH  TEMPERATE 

AMERICA. 

BY 

C.  H.  EIGENMANN, 
INDIANA  UNIVERSITY. 

IN  the  following  list  are  enumerated  the  orders,  families,  genera  and 
species  of  fishes  inhabiting  the  fresh  waters  of  the  West    Indies, 
South  America,  and  Middle  America  south  of  a  line  joining  the  Rio 
Panuco  on  the  east  and  the  Rio  Presidio  near  Mazatlan  on  the  west.     The 
list  attempts  to  be  complete  to  June,  1909.* 

Under  each  genus  will  be  found  the  synonyms  and  the  type  of  the 
genus,  and  the  total  range  of  its  species.  The  range  will  be  the  sum  of 
the  distributions  of  the  species  enumerated,  except  in  cases  of  genera 
having  extralimital  species. 

Under  each  species  are  given  its  synonyms  and  the  geographical  dis- 
tribution. 

Opposite  each  species,  except  in  the  case  of  the  Characins  and  species 
dealt  with  in  the  Patagonian  section  of  this  work,  will  be  given  a  refer- 
ence which  will  connect  this  work  with  the  literature  on  the  species. 

A  catalogue  of  the  fresh-water  fishes  of  South  America  was  published 
by  Eigenmann  and  Eigenmann  in  the  Proceedings  of  the  United  States 
National  Museum,  1891,  and  a  catalogue  of  the  Middle  American  species 
in  the  same  serial  for  1892.  Free  use  has  been  made  of  these  catalogues. 
The  task  of  bringing  the  work  down  to  date  has  been  greatly  lessened 
by  the  following  works  of  recent  years  : 
Jordan  &  Evermann,  Fishes  of  North  and  Middle  America.  Bull.  U.  S. 

Nat.  Mus.,  47,  Washington,  1896-1898. 

*The  entire  MS.  was  completed  to  1906.  Delay  in  publication  has  enabled  me  to  bring  the 
catalogue  down  to  June,  1909.  In  consequence  of  bringing  the  catalogue  down  to  1909  some 
discrepancies  between  the  preceding  and  following  lists  of  species  will  be  found.  An  especially 
large  number  of  additions  are  made  to  the  Characins  and  the  fauna  of  Guiana.

Eigenmann,  C.  H.,  The  American  Characidae,  in  MS. 

These  papers,  exclusive  of  the  MS.  monograph  on  the  Characidae,  are 
referred  to  under  the  name  of  the  author  and  the  page.  Other  papers  are 
quoted  by  the  author,  year  of  publication  and  the  page.  The  full  titles 
may  readily  be  found  in  the  bibliography  at  the  end  of  the  Catalogue. 

All  fishes  recorded  from  fresh  water  are  enumerated.  In  tropical 
America  many  marine  species  enter  fresh  water.  Some  of  these  do  not 
go  far  beyond  the  mouths  of  rivers,  others  ascend  streams  several  thou- 
sand miles.  Perhaps  some  of  the  marine  species  enumerated  should  have 
been  excluded,  probably  others  should  have  bee'n  added.  The  author  will 
be  very  glad  to  be  informed  of  any  omissions  or  errors  of  any  sort. 

In  order  to  emphasize  the  Pacific  slope  fauna  the  species  from  this  area 
are  in  heavy  type.  To  readily  distinguish  the  Amazonian  species,  these 
are  preceded  by  an  A.

relationships,  and  for  the  purpose  of  discussing  the  geo- 
graphical distribution,  it  will  be  better  to  recognize  a 
larger  number  of  genera.  My  estimate  of  the  character 
of  these  can  best  be  expressed  by  the  following  key,  in 
which  I  have  followed  to  a  very  large  extent  the 
phraseology  of  Regan,  but  in  which  are  recognized 
a  larger  number  of  genera  than  are  admitted  by  him. 
The  list  of  species  is  accepted  with  but  slight  modifica- 
tions from  Regan.

Habitat:  Amazons. 

1  Doubtful  species  of  this  genus  are  Citcetostomus 
sericeus  Cope  and  Hypostomus  erinaceus  C.  &  V. 

Kner  (1853)  described  the  genus  Ancistrus  to  in- 
clude many  species,  which  he  divides  into  the  two 
groups,  Brachypteri,  D.  I,  7-!,  9,  and  Macropteri,  D.  I, 
u-I,  13. 

Gill  (1859)  separated  the  Macropteri  under  the  name 
Pterygoplichthys,  saying:  "The  genus  Ancistrus  seems 
to  have  been  framed  with  special  regard  to  those  fishes 
to  which  the  name  is  here  restricted,  and  is  by  Dr.  Kner 
divided  into  tw»  sections,  which  correspond  to  Ancistrus 
and  Pterygoplichthys,  his  section  a  answering  to  the 
former  genus  and  b  to  the  latter." 

The  species  known  to  Kner  and  included  in  his 
Brachypteri  are:  Hypostomus  cirrhosus  C.  &  V,  An- 
cistrus dolichopterus  Kner,  Ancistrus  gymnorhynchus 
Kner,  Ancistrus  mystacinus  Kner,  Ancistrus  pictus 
Kner,  Ancistrus  brachyurus  Kner,  Ancistrus  scaphirhyn- 
chus  Kner.  There  can  be  no  mistake  as  to  what  Gill 
meant. 

Gill  redescribed  the  genus  Ancistrus,  not  to  restrict

it,  but  as  he  described  or  redescribed  all  of  the  other 
genera  of  fresh-water  fishes  from  Trinidad. 

His  description  of  Ancistrus  was  either  drawn  from 
his  specimens  of  guacharote  or  from  Cuvier  &  Valen- 
cienne's  (XV,  508)  description  of  guacharote.  Gua- 
charote was  known  to  Kner  only  through  C.  &  V.'s 
description  and  on  account  "  der  Ungenauigkeit  der 
Beschreibung  ",  he  was  unable  to  place  it  with  certainty. 
He  thought  it  might  be  his  mystacinus. 

Regan  considers  guacharote  as  belonging  to  his  new 
subgenus  Lasiancistrus.  But  because  Gill's  wording  of 
the  description  applies  only  to  brachyurus  and  scaphi- 
rhynchus  (and  medians)  of  Kner,  Regan  considers  the 
latter  typical  of  Ancistrus.  Gill's  diagnosis  based  on 
guacharote,  a  species  not  known  to  Kner  and  at  least 
subgenerically  distinct  from  brachyurus  and  scaphi- 
rhynchus,  can  have  no  bearing  whatever  on  the  restric- 
tion of  Ancistrus. 

Fortunately  Bleeker  definitely  restricted  the  name  to 
Kner's  first  species,  cirrhosus.

Family  CYCLOPID^. 


CYCLOPIUM   Swainson.1 
Arges  and  Brontes  Cuvier  &  Valencien- 
nes ;  Sty  go  genes  Gunther. 

1 1  have  retained  the  species  of  this  family  as  recog- 
nized by  Regan.  Evermann  &  Kendall  (Proc.  Biol. 
Soc.,  Wash.,  xviii,  p.  91,  1905)  think  that  many  are 
probably  synonyms. 

I  am  not  certain  of  the  position  of  most  of  the 
localities  of  this  genus,  whether  on  the  Amazonian  or 
Pacific  slope.  I  have  taken  it  for  granted  that  they  are 
from  the  Atlantic  slope  unless  specifically  stated  that 
they  are  from  the  Pacific  side.

1  In  a  recent  paper  (The  Gymnotidae,  Proc.  Wash. 
Acad.  Sci.,  VII,  p.  174)  I  followed  Gill  in  using  the 
name  Gymnotus  for  the  current  Gymnotus  carapo 
Linnaeus,  this  species  being  the  only  one  described 
by  Linnaeus  in  his  tenth  edition.  No  doubt  seems  to 
have  been  entertained  about  the  nature  of  the  Gymnotus 
carapo  of  Linnaeus  and  its  supposed  synonymy  and 
bibliography  were  given  in  the  paper  quoted  above, 
P-  175- 

Mr.  Lonnberg  has  kindly  called  my  attention  to  his 
paper  (Bihang  till  K.  Svenska  Vet.-Akad.  Handb., 
XXII,  Afd.  IV,  23,  1896)  on  Linnean  Type-specimens 
in  which  he  has  shown  that  the  type  of  Linnaeus  is 
not  the  current  Gymnotus  carapo,  but  the  Gymnotus 
fasciatus  of  Pallas  or  Giton  fasciatus  Auct.  The  latter 


Type :  Synbranchus  marmoratus  Bloch. 
Range :  Tropical  America  and  Indies. 
Ai.  Synbranchus  marmoratus  Bloch,

species  must  therefore  stand  as  Gymnotus  carapo  Lin- 
naeus, the  name  Gymnotus  replacing  the  more  recent 
Giton. 

The  current  Gymnotus  carapus  must  be  known  by  its 
oldest  name,  which  is  macrurus  Bloch  &  Schneider. 
Miiller  &  Troschel  in  1849  proposed  the  name  Sterno- 
pygus for  macrurus,  tumifrons,  virescens,  lineatus,  and 
aquilabiatus.  In  1894  I  selected  as  the  type  of  Sterno- 
pygus the  then  current  carapo,  of  which  macrurus  was 
a  synonym.  The  fact  that  the  name  carapo  of  Linnaeus 
did  not  refer  to  the  species  under  consideration  need 
not  invalidate  this  restriction,  since  there  was  no  doubt 
whatever  about  the  fish  that  was  intended  to  serve  as 
type.  It  may  stand  as  Sternopygus  macrurus  (Bloch  & 
Schneider) .

Inasmuch  as  the  species  described  by  Heckel  in- 
cluded members  of  four  distinct  genera  and  since  he 
added  members  of  three  other  genera  from  species 
known  to  him  from  descriptions,  we  cannot  say  that  he 
had  any  very  definite  thing  in  mind  when  he  framed 
the  genus. 

In  the  generic  description  he  refers  to  figures  of  the 
lower  pharyngeals  and  gill-arches  of  Acara  tetramerus 
and  crassispinis. 

As  far  as  Heckel's  work  is  concerned,  his  Acara, 
containing  the  type  of  Swainson's  Astronotus  (to  the 
figure  of  which  Heckel  definitely  refers  in  his  generic 
description)  might  be  a  synonym  of  Astronotus  or 
separate  from  it,  depending  altogether  on  which  of  his 
species,  if  any,  he  considered  his  type.  If  any  presump- 
tion is  permitted,  it  must  be  in  favor  of  his  first  species 
or  the  last,  or  one  of  the  species  whose  figures  are 
referred  to  in  his  generic  description.  The  first  species 
is  a  synonym  of  Sci&na  bimaculata  Linnaeus  and  be- 
longs to  the  genus  Cichlasoma  of  Swainson.  If  the 
first  species  is  selected,  the  name  Acara  becomes  a  syn- 
onym of  Cichlasoma.  If  the  last  species,  crassispinis, 
is  selected,  Acara  becomes  a  synonym  of  Astronotus, 


Heckel;  Chromys  punctata  and  uni- 
ocellata  Castelnau. 

Habitat :  Essequibo ;  Amazons  south  to 
Rio  Janeiro  and  Paraguay. 

since  crassispinis  is  a  synonym  of  ocellatus,  the  type  of 
the  latter  genus.  If  one  of  the  two  species  figured  is 
selected  we  may  have  tetramerus  or  again  crassispinis 
as  the  type  for  Acara.  If  the  former  is  selected  the 
name  Acara  will  stand. 

Inasmuch  as  Heckel  does  not  select  a  type,  it  is 
incumbent  on  a  later  naturalist  to  select  a  type  from 
among  the  four  species  discussed,  or  from  among  any 
of  Heckel's  species. 

In  the  earliest  paper  by  Gill  (Synopsis  of  the  Fresh- 
Water  Fishes  of  Trinidad)  he  says,  p.  19:  "As  it 
[Labrus  punctatus,  the  type  of  Cichlasoma']  is  a  true 
Acara,  the  latter  genus  is  consequently  synonymous  with 
Cychlasoma,  and  in  accordance  with  the  law  of  priority, 
the  Swainsonian  name  must  be  adopted  as  that  of  the 
present  genus."  Gill  re-defines  the  genus  Cichlasoma, 
excluding  several  of  Heckel's  species,  and  continues: 
"  With  these  characters,  that  species  which  Mr.  Heckel 
.  .  .  has  described  as  the  Acara  crassispinis,  will  also 
be  excluded  [from  the  genus  Cichlasoma']  ;  this  species 
appears  to  be  generically  distinct  from  both  Cychlasoma 
and  from  Astronotus  of  Swainson.  ...  If  it  should  be 
found,  on  a  more  critical  examination,  to  be  really 
distinct  from  Astronotus,  to  which  it  is  most  nearly 
allied,  Heckel's  name  of  Acara  might  appropriately  be 
retained  as  its  generic  name.  ...  It  belongs  to  the 
section  E  of  the  genus  Acara,  in  the  arrangement  of 
Heckel  .  .  . ;  the  other  sections  ...  all  belong  to 
Cychlasoma  as  now  restricted." 

Gill  thus  removed  from  Acara  all  of  Heckel's  species 
but  crassispinis. 

There  can  be  no  question  that  it  was  entirely  within 
the  province  of  Gill  to  restrict  the  genus  to  this  species. 
But  it  was  found  later  that  crassispinis  is  a  synonym  of 
ocellatus,  the  type  of  Astronotus.  Acara  is  therefore 
the  exact  synonym  of  Astronotus  and  cannot  be  used  for 
anything  else.  Inasmuch  as  tetramerus  and  other  spe- 
cies are  distinct  from  Astronotus,  I  coined  the  name 
/Equidens  for  them  in  1894.  (Ann.  N.  Y.  Acad.  Sci., 
VII,  616,  using  the  Acara  tetramerus  Heckel  as  type.) 

The  name  Acara  has  been  resurrected  by  Regan  (Ann. 
and  Mag.  Nat.  Hist.  (7),  XV,  1905,  p.  330),  who  says: 
"  After  removing  from  Heckel's  genus  the  species 
which  belong  to  Astronotus,  Cichlasoma  and  Acaropsis, 
I  use  Acara  for  the  remainder,  regarding  Gill's  restric- 
tion of  the  name  Acara  to  a  species  which  was  already 
the  type  of  another  genus  as  invalid." 

I  know  of  no  rule,  ancient  or  modern,  of  scientific 
nomenclature  which  authorizes  anyone  to  regard  as 
invalid  the  work  done  by  someone  else,  unless  that  work 
was  done  contrary  to  the  accepted  canons.  In  fact,  the 
rules  (if  I  am  not  mistaken)  have  been  made  especially 
to  prevent  this  sort  of  procedure.

NON-MARINE  MOLLUSCA  OF  PATAGONIA. 

BY 

HENRY  A.  PILSBRY, 
ACADEMY  OF  NATURAL  SCIENCES,  PHILADELPHIA. 

This  report  deals  with  the  non-marine  mollusks  of  Tierra  del  Fuego 
and  Patagonia  as  far  north  as  the  thirty-ninth  parallel,  where  the  Rio 
Negro  Valley  forms  a  transition  region,  the  Patagonian  fauna  giving  place 
to  the  La  Platan. 

The  scope  of  the  work  has  been  extended  to  include  some  account  of 
all  the  South  American  forms  of  certain  little-known  families,  such  as  the 
AmmcoBda  and  Spliczriidce,  and  all  of  the  Chilinida  occurring  east  of  the 
Andes.  Finally,  the  relationships  of  the  South  American  molluscan  fauna 
with  the  faunas  of  other  continents  are  considered. 

The  collections  made  by  Mr.  J.  B.  Hatcher  and  placed  in  my  hands  by 
Professor  William  B.  Scott  form  the  basis  of  this  report.  The  material 
from  the  region  along  the  Rio  Chico  de  la  Santa  Cruz  and  in  the  base  of 
the  Andes  above  its  head  is  ample.  Elsewhere  but  few  mollusks  were 
collected,  and  I  have  used  material  which  I  owe  to  the  generosity  of  Dr. 
H.  von  Ihering,  Director  of  the  Museu  Paulista,  Dr.  W.  H.  Rush,  U.S.N., 
and  others. 

ZONAL  DISTRIBUTION  OF  PATAGONIAN  MOLLUSCA. 

An  inspection  of  the  data  existing  on  Patagonian  mollusks  shows  that 
several  faunulas  largely  distinct  in  species  occupy  zones  extending  from 
the  Atlantic  to  the  Andes  and  succeeding  one  another  from  north  to  south. 
So  far  as  aquatic  animals  are  concerned,  these  zones  are  determined  by 
the  drainage  systems,  which  are  separated  by  poorly  wratered  plains,  and 
flow  independently  into  the  Atlantic.  The  aquatic  mollusks  known  from 
these  several  zones  are  enumerated  below. 

C/n'liiia,  Lymncea  and  Pisidium  are  the  only  genera  of  fresh-water  mol- 
lusks which  extend  throughout  Patagonia,  the  first  two  also  in  Tierra  del

Fuego.  The  Unionidce  and  Mutelidce,  groups  copiously  represented  in  the 
La  Plata,  have  their  southern  limit  in  the  Rio  Negro,  each  represented  by 
one  species  ;  Planorbis  has  two,  Ancylus  one  species,  the  rest  of  the  fauna 
being  Patagonian.  The  Rio  Negro  fauna,  including  the  region  of  Bahia 
Blanca,  is  transitional  also  in  land  mollusks,  the  genera  Bulimulus,  Odon- 
tostomus  and  Strophocheilus  reaching  their  southern  limit  in  the  Sierra 
Ventana,  near  Bahia  Blanca.  In  the  humid  region  west  of  the  Cor- 
dillera the  faunal  zones  are  deflected  southward,  the  transition  zone  as 
marked  by  the  southern  limit  of  Unionidce  being  in  the  neighborhood  of 
Chiloe  Island.  That  the  transverse  faunal  zones  of  Patagonia  run  north- 
ward in  the  Andean  region  is  shown  by  the  occurrence  on  the  upper  Rio 
Chico  of  several  Magellanic  forms. 

I.    LA  PLATAN  ZoNE.1 

Includes  the  Plata  and  its  tributaries  in  Argentina,  Uruguay,  .Paraguay, 
Brazil,  and  rivers  flowing  into  the  Atlantic  in  the  Brazilian  states  of  Sao 
Paulo  and  Rio  Grande  do  Sul.     Except  in  Chilinida,  only  the  genera  of 
this  fauna  are  mentioned  below,  the  species  being  very  numerous. 
Chilinidae:  Chilina  fluminea,  C.  f.  microdon,  C.  globosa,  C.  rushii,  C.  parva, 

C.  portillensis,  C.  tehuelcha  mendozana. 
Physidae :  Physa.

flavida. 
Sphaeriidae :  Pisidium  magellanicum. 

These  several  faunas  may  be  roughly  compared  with  the  life-zones  of 
North  America.  The  La  Platan  zone  is  equivalent  to  the  Austral,  the  Rio 
Negro  fauna  to  the  Transition,  and  the  remainder  of  the  Patagonian  zone 
to  the  Boreal  zone  of  the  northern  continent. 

The  distinctness  of  the  Patagonian  faunas  A,  C,  D  may  be  attributed 
to  three  main  factors  :  (i)  Climate,  which  imposes  limits  on  the  north 
or  south  distribution  of  species.  (2)  Absence  of  streams  flowing  north  or 
south,  and  the  consequent  isolation  of  the  river  systems,  favoring  the  evo-

lution  of  distinct  species.  (3)  Ignorance  of  the  Patagonian  faunas  be- 
tween the  Rio  Negro  and  the  Rio  Santa  Cruz  system,  and  along  the  base 
of  the  Andes,  where  Transition  forms  and  intermingling  of  the  species 
may  occur. 

GASTROPODA. 

Family  ENDODONTIDsE. 

Two  genera  of  this  family  are  known  from  Patagonia :  Stephanoda  and 
Radiodiscus.  The  relationships  of  these  forms  to  genera  of  other  regions 
are  unknown,  since  we  have  as  yet  no  knowledge  of  their  soft  anatomy. 
Endodontidce  were  present  in  the  North  American  Carboniferous,  repre- 
sented by  forms  resembling  the  modern  Gonyodiscus  and  Charopa  in  shell 
characters,  and  like  their  descendants,  living  in  and  upon  decaying  stumps. 
The  family  is  now  found  all  over  the  world,  even  on  the  most  remote 

islands. 

RADIODISCUS  Pilsbry. 

Radiodiscus  Pils.,  Proc.  A.  N.  S.  Phila.,  1906,  p.  154,  for  R.  milleco  status. 

Minute,  discoidal,  openly  umbilicate  Patuloid  snails,  with  the  embryonic 
\Y^  whorls  minutely  engraved  spirally,  the  rest  of  the  shell  densely  radi- 
ally costulate.  Aperture  rotund-lunate,  but  slightly  oblique,  and  as  high 
as  wide.  Type  R.  millecostatus  Pils.  &  Ferr. 

In  the  Endodontidce,  where  small  differences  in  the  shell  characterize 
extensive  series  of  species,  it  seems  desirable  to  recognize  as  of  generic 
rank  such  readily  definable  groups  as  Radiodiscus. 

The  distribution  of  this  genus  is  very  wide,  extending  from  Tierra  del 
Fuego  to  the  mountain  ranges  of  the  southern  boundary  of  Arizona,  where 
it  meets  the  Holarctic  Gonyodiscus  and  the  Nearctic  Helicodiscus,  both  at 
their  southern  limits.  At  present,  the  known  distribution  of  Radiodiscus 
is  markedly  discontinuous,  one  area  extending  from  southern  Arizona  to 
central  Mexico,  the  other  from  southern  Brazil  to  Cape  Horn  ;  yet  it  must 
be  remembered  that  the  Andes  and  northern  South  America  are  un- 
searched  for  minute  shells.  We  know  very  few  so  small  as  these  (2  to 
3  mm.  diam.);  and  some  of  the  species  imperfectly  described  may  turn 
out  to  belong  to  Radiodiscus.  It  is  likely  that  the  group  is  an  Austral 
one,  which  has  invaded  Mexico  from  the  south. 

Some  Tasmanian  snails  have  a  great  resemblance  to  Radiodiscus,  in

size,  form  and  sculpture  —  a  resemblance  possibly  due  to  convergence,  but 
perhaps  indicating  affinity.  I  have  not  been  able  to  actually  compare 
specimens.  On  account  of  their  spirally  sculptured  embryonic  shells 
Hedley  has  referred  them  to  the  subgenus  Allodiscus  of  the  genus  Flam- 
mulina.  J

Patula  coppingeri  Smith,  Strebel,  Zool.  Jahrb.,  XXV,  1907,  p.  159. 

The  shell  is  described  as  i  X  i#  mm.,  composed  of  y/2  whorls,  the 
"  umbilicus  moderately  small,  equalling  about  one-sixth  of  the  basal 
diameter." 

It  was  described  from  Tom  Bay  (Dr.  Coppinger),  found  on  a  rotten 
tree.  This  is  near  Madre  de  Dios  Island,  on  the  west  coast.  Strebel 
reports  specimens  which  he  identified  as  coppingeri  from  the  west  coast 
of  Tierra  del  Fuego,  Ushuaia,  and  Navarin  Island.  While  this  form  must 
stand  near  R.  patagonicus,  it  appears  distinct  by  the  much  smaller  um- 
bilicus, if  we  may  trust  the  published  figures.  I  have  not  seen  specimens. 
The  apical  sculpture  has  not  been  described.

This  species,  described  from  the  same  place  as  the  preceding,  will  prob- 
ably prove  to  be  a  Radiodiscus,  when  the  embryonic  whorls  are  examined.

The  shell  is  openly  umbilicate  (the  umbilicus  about  one-fourth  the  total 
diameter),  of  a  uniform  pale  brown  tint,  discoidal,  the  spire  convex  but 
low,  suture  deeply  impressed.  Whorls  about  3^  ,  convex,  slowly  increas- 
ing, the  embryonic  i  y2  densely  striate  spirally,  the  rest  radially  costellate,

the  riblets  about  as  wide  as  their  intervals,  about  25  in  i  mm.  on  the  last 
half  of  the  last  whorl.  Under  the  microscope  some  very  minute  striations 
may  be  seen  upon  the  ribs,  and  in  places  an  extremely  minute  and  very 
faint  spiral  striation.  The  rotund-lunate  aperture  is  slightly  oblique.

The  above  description  and  the  figures  are  from  a  shell  collected  alive 
50  miles  above  the  Sierra  Oveja.  The  original  description,  in  Portuguese, 
was  based  upon  fossil  specimens,  which  had  lost  the  color  and  part  of  the 
finer  sculpture.  The  original  lot  of  patagonicus  was  from  Santa  Cruz,  on 
the  coast,  in  a  modern  deposit.  Part  of  the  original  lot  is  before  me. 
They  are  a  little  larger  than  the  living  shell  described,  with  the  whorls 
slightly  deeper  ;  yet  in  the  series  examined  from  all  of  the  localities  yet 
known,  the  very  slight  differences  seem  to  intergrade. 

STEPHANODA  Albers. 

This  group  comprises  Patuloid  species  in  which  the  embryonic  whorl  is 
typically  smooth,  but  in  some  forms  now  referred  here  it  is  marked  with 
radial  striae,  but  no  spirals.  It  differs  from  Amphidoxa  (with  which  I 
formerly  united  it)  by  the  more  numerous,  less  rapidly  widening  whorls. 
Without  a  knowledge  of  the  soft  parts,  the  relationships  of  these  South 
American  snails  to  the  Austral  Charopa  and  Flammulina,  and  to  the  northern 
Patuliform  genera,  cannot  be  defined.  The  following  species  from  southern 
Patagonia  belong  here : 
S.  lyrata  (Gld.),  summit  of  highest  mountain  near  Orange  Harbor,  etc.

Family   ZONITIDsE. 

The  small  land  snails  originally  described  as  Helix  saxatilis  Gld.  and 
H.  ordinaria  Smith  have  all  the  external  characters  of  the  Hyalinia  group 
of  Zonitidce.  H.  saxatilis  has  pedal  grooves  and  a  mucous  pore  at  the 
tail.  Mabille  and  Rochebrune  have  proposed  for  it  the  generic  term 
Payenia.  What  status  this  group  will  ultimately  be  given  depends  wholly 
upon  the  internal  anatomy,  of  which  we  know  nothing.  It  may  possibly 
belong  to  the  Endodontidce.

from  honey-yellow  to  whitish-yellow,  always  with  the  first  whorl  of  a 
deeper  yellow  shade.  The  suture  is  very  deep  and  the  whorls  extremely 
convex.  The  specimens  figured  measure  :

It  will  be  noted  that,  as  compared  with  Doering's  description,  these  shells 
have  the  aperture  shorter. 

At  all  other  stations  the  shells  are  smaller.  Two  figured  from  the  Rio

LYMN^A    Lamarck. 

Lymncea  is  more  widely  distributed  than  any  other  genus  of  freshwater 
mollusks,  extending  from  the  shores  of  the  Arctic  Ocean  to  Tasmania  and 
Cape  Horn,  and  in  the  Pacific  reaching  the  Hawaiian  group.  The  genus 
in  its  present  limits  is  a  synthetic  group,  which  no  doubt  will  ultimately 
be  divided  into  several  genera. 

There  are  very  few  species  in  tropical  South  America,  where  the  genus 
seems  to  be  of  rare  occurrence ;  but  in  Patagonia  the  species  are  more 
numerous,  individuals  are  abundant  and  generally  distributed.  South 
American  Lymnaeas  fall  into  three  subgenera  or  sections  of  the  genus. 
Section  I  is  clearly  an  intrusive  element  from  North  America.  Sec- 
tion II  may  possibly  be  of  North  American  origin,  but  its  relationships 
are  unknown,  as  no  specimens  with  the  soft  parts  have  been  received. 
Section  III  is  peculiar  to  Patagonia,  and  not  closely  related  to  any  nor- 
thern forms. 

I.  Section  GALBA  Schrank.     The  marginal  teeth  of  the  radula  differ 
from  the  laterals  by  being  more  oblique,  but  are  essentially  tr^ispid.    The 
shell  is  small,  compactly  coiled,  of  very  convex  whorls,  usually  umbilicate, 
the  columellar  lip  broadly  revolute,  not  folded.     The  type  is  L.  truncafala

tonica.     It  is  possible  that  the  presence  of  acid  in  the  water,  causing  erosion 
of  the  shell,  may  also  account  for  the  stunted  stature  of  these  forms. 

DENTITION  OF  SOUTH  AMERICAN  LYMN^EAS. 

Dentition  of  L.  viator  d'Orb. — The  radula  examined  was  from  one  of 
the  specimens  taken  on  the  Rio  Chico  near  the  Sierra  Oveja.  The  central 
tooth  is  narrow  and  unicuspid  as  usual.  There  are  three  or  four  lateral 
teeth,  having  two  long  cusps.  In  the  following  transition  teeth  the  inner 
cusp  (entocone  +  mesocone)  is  long  and  bifid,  ectocone  simple.  The

marginal  teeth  are  very  oblique,  with  three  cusps,  entocone,  mesocone  and 
ectocone.  In  some  of  the  outer  marginal  teeth  there  may  be  one  or  two 
minute  accessory  cusps. 

The  radula  of  L.  viator  agrees  well  with  that  of  the  European  L.  trun- 
catula  as  figured  by  Lehmann.  It  differs  from  typical  Lymncea  by  retain- 
ing the  primitive  tricuspid  type  of  teeth  in  the  marginal  series,  with  few 
small  accessory  cusps  or  none.  Lymnaeas  with  this  type  of  teeth  have  a 
continuous  distribution  from  Patagonia  to  Alaska  and  in  the  Palaearctic 
region. 

Dentition  of  Lymncea  diaphana  King. — These  are  about  30,  7,  I,  7, 
30  teeth.  The  central  tooth  is  wider  than  usual  in  Lymneea,  unicuspid. 
The  lateral  teeth  are  bicuspid,  the  broad  inner  cusp  becoming  bifid  on 
the  transition  teeth.  The  inner  marginals  have  the  mesocone  and  ento-

parallel  to  the  long  axis  of  the  tooth,  and  are  split  into  a  comb-like  series 
of  denticles. 

The  marginal  teeth  of  L.  diaphana  differ  from  those  of  typical  Lymncea 
by  their  prostrate  position,  the  cusp  of  one  tooth  overlying  the  basal  plate 
of  the  succeeding  one  in  the  same  transverse  row,  and  also  by  the  comb- 
like  cusps.  In  typical  Lymncea  (L.  stagnalis,  fig.  3)  the  cusp  stands 
obliquely  erect,  its  cutting  edge  transverse  to  the  long  axis  of  the  tooth.

Marginal  teeth  of  Lymn<za  stagnalis  L.  Two  outer  lateral  and  two  inner  marginal

Lymncea  patagonica  riochicoensis  (fig.  4,  two  outer  lateral  and  two  inner 
marginal  teeth)  has  a  radula  closely  resembling  that  of  L.  diaphana. 
There  are  ten  lateral  teeth. 

No  Lymncea  of  the  northern  hemisphere,  of  which  the  teeth  are  known, 
has  marginals  like  those  of  L.  diaphana,  but  I  have  shown  that  some- 
what similar  teeth  exist  in  a  Hawaiian  species.1

A  species  of  the  group  of  L.  truncatula.  The  shell  is  small  and 
smoothish,  composed  of  five  very  convex  whorls,  joined  by  a  very  deep 
suture  ;  the  aperture  is  oval  or  nearly  round,  more  than  half  the  length  of 
the  shell.  The  axis  is  very  distinctly  umbilicate.  Length  8,  diam.  4  mm. 

d'Orbigny  records  this  species  from  the  banks  of  the  Rio  Negro,  41°  S. 
lat,  7  or  8  leagues  above  the  mouth,  very  abundant.  This  may  be  con- 
sidered the  type  locality.  Afterwards  he  collected  it  also  at  Santiago, 
Chili,  and  at  Callao  and  Lima,  Peru,  in  irrigation  ditches.  The  speci- 
mens from  Peru,  he  notes,  are  constantly  more  elongate  than  those  of 
Patagonia  and  Chili,  with  the  whorls  more  deeply  separated.  Dr.  W.  H. 
Rush  collected  many  specimens  in  a  creek  in  the  Prado,  at  Montevideo, 
Uruguay.  These  specimens,  with  others  from  Lima  before  me,  do  not 
seem  separable  from  the  Antillean  L.  ctibensis  Pfr.  (1840)  by  any  character 
in  the  shells. 

Specimens  from  a  pool  on  the  bank  of  the  Rio  Chico,  a  mile  west  of 
the  Sierra  Oveja  (PI.  XLVI,  fig.  8)  are  larger  than  those  from  Uruguay, 
the  individual  figured  measuring  length  10,  diam.  5.1,  length  of  aperture 
5  mm.,  whorls  5^.  The  spire  is  longer,  and  the  umbilicus  somewhat 
narrower.  The  columellar  margin  is  broadly  revolute  and  without  fold 
or  perceptible  sinuosity.  This  form  differs  from  that  figured  by  d'Orbigny, 
and  from  the  Montevideo  shells  examined,  chiefly  by  having  a  longer  spire 
and  shorter  aperture,  the  latter  half  as  long  as  the  shell ;  by  having  more 
whorls,  a  smaller  umbilicus,  and  by  its  somewhat  greater  size.

King's  type  measured  about  17  X  7.5  mm.  ;  Strebel's  shells  were  smaller, 
10-13  mm.  long,  and  he  seems  to  have  entertained  some  doubt  of  their 
identity  with  King's.  L.  lebruni  is  described  as  16  to  20  mm.  long,  and 
agrees  well  with  L.  diaphana  in  other  respects.  It  may  be  noted  that 
Mabille  and  Rochebrune  do  not  mention  L.  diaphana,  and  evidently 
overlooked  it. 

On  the  Rio  Chico  de  la  Santa  Cruz  Mr.  Hatcher  collected  numerous 
Lymnaeas  of  the  L.  diaphana  type,  some  agreeing  with  the  typical  form 
from  the  Straits  of  Magellan,  others  divergent  therefrom. 

In  what  I  take  to  be  typical  L.  diaphana,  from  a  spring  on  the  Rio 
Chico,  15  miles  above  the  Sierra  Oveja  (PI.  XLVI,  figs.  3,  7,  9)  the 
shell  is  thin,  but  moderately  strong,  narrowly  rimate,  rather  long,  the  last 
whorl  swollen,  but  much  smaller  than  in  L.  d.  inelegans,  very  evenly 
rounded,  with  sculpture  of  unequal  growth-lines,  but  not  malleated,  and 
very  glossy.  The  spire  is  long,  slender  and  acuminate.  The  shortly 
ovate  aperture  is  rather  small  ;  columella  very  narrowly  revolute,  not 
adnate  above,  continuing  free  to  the  parietal  wall  above  the  axial  crevice. 
The  color  is  light  brown,  or,  when  the  cuticle  is  worn  off,  pink,  or  pinkish 
white.  Specimens  measure  :

The  shell  is  narrowly  rimate,  short  and  wide,  the  last  whorl  dispropor- 
tionately large,  inflated,  with  sculpture  of  rather  coarse  growth-wrinkles 
and  more  or  less  malleation.  The  spire  is  small,  shortly  conic.  Aper-

4,  6).  Small  stream,  35  miles  above  Sierra  Oveja  (fig.  5). 

The  specimens  from  the  second  locality  mentioned  are  more  regular  in 
contour.  Up  to  a  length  of  15^  to  16  mm.  the  surface  shows  no  mallea- 
tion, and  at  that  size  the  shells  of  this  lot  reach  maturity.  The  lip 
expands  slightly  and  a  very  thin,  white,  submarginal  callus  strengthens  it. 
In  one  individual  growth  has  proceeded  beyond  this  stage,  the  part  added 
being  strongly  malleated.  This  shell  (PI.  XLVI,  fig.  5)  measures,  length 
17,  diam.  10,  length  of  aperture  9.8  mm.;  whorls  5. 

In  two  of  the  four  lots  from  "springs  on  the  Rio  Chico,  25  miles  above 
Sierra  Oveja,"  there  are  some  dwarf  individuals.  One  measures,  length 
10,  diam.  6,  aperture  6.5  mm.;  whorls  4%.  In  another  lot,  all  the  shells 
are  similarly  dwarfed. 

In  the  Rio  Chico,  50  miles  above  Sierra  Oveja,  a  similar  dwarf  shell 
was  taken. 

In  and  near  drying  pools  on  a  high  divide  near  the  base  of  the  Andes, 
50  miles  north  of  the  Rio  Chico,  elevation  2400  ft.,  the  shells  are  very 
fragile,  pale,  dull  buff,  with  strongly  developed,  low,  wave-like  costation

and  more  or  less  malleation.  One  measures,  length  14,  diam.  8,  length 
of  aperture  8.6  mm.;  whorls  45^.  Those  from  the  Arroyo  Eke,  near  the 
head  of  Spring  Creek,  are  also  small. 

In  Swan  Lake  (about  50  miles  north  of  the  Rio  Chico)  the  shells  are 
very  delicate,  almost  like  tissue  paper,  but  little  malleated  or  (usually) 
without  malleation,  and  of  a  pale  olive  color.  Most  of  the  examples  con- 
form nearly  to  PI.  XLVItf,  fig.  2,  in  shape,  but  I  have  also  figured  the  most 
elongate  (fig.  i)  and  the  shortest  (fig.  3)  shells.  Fig.  2  measures,  length 
19,  diam.  n,  length  of  aperture  10.9  mm.;  whorls  4^4. 

Mr.  Hatcher  in  his  narrative  has  alluded  to  the  abundance  of  shells  in 
this  lake  (Reports  of  the  Princeton  University  Expeditions  to  Patagonia, 
I,  p.  166).  The  lake  basin  is  composed  of  igneous  rocks  dammed  by  a 
lava  flow.  To  the  absence  of  calcareous  material,  the  tenuity  of  the  shells 
is  probably  due.

is  described  as  wider,  more  opaque  and  darker  than  L.  diaphana,  alt.  14,

Strebel's  types  are  said  to  differ  from  the  form  he  describes  as  L. 
diaphana  by  being  browner,  more  of  a  chestnut-brown,  the  whorls  in- 
crease more  rapidly  in  width,  the  apex  is  commonly  broken,  with  the 
breach  closed  by  shell-material ;  the  columella  stands  more  nearly  vertical, 
and  its  reflection  is  somewhat  wider,  but  leaves  an  umbilical  crevice  open. 
It  measures  as  follows  :

is  imperf orate.  It  is  pale  honey-yellow  or  very  pale  yellowisli-brown.  In

an  entire  specimen  (fig.  n)  there  are  3%  convex  and  rapidly  enlarging 
whorls,  the  last  inconspicuously  marked  with  rather  widely  spaced,  very 
low  longitudinal  wrinkles,  and  some  weak  malleation  in  places.  The 
aperture  appears  to  be  less  rounded  than  in  L.  patagonica.  The  parietal 
and  axial  callus  is  a  mere  transparent  film  (not  distinct  as  shown  in  fig. 
1 1 ),  closely  adnate  throughout.  The  columella  is  white,  solid  and  rounded, 
nearly  straight,  and  without  trace  of  a  fold.  The  largest  specimen  (fig. 
1 1 )  measures :

river  under  stones,  numerous  specimens.  Also  in  a  pool  near  the  Sierra 
Oveja,  one  characteristic  individual. 

Most  of  the  adult  examples  taken  are  very  much  eroded,  the  spire  re- 
moved, and  the  last  whorl  deeply  eaten  in  places,  as  though  by  acid. 
The  parietal  callus  is  thick,  with  the  outer  edge  distinctly  raised.  The 
external  erosion  is  compensated  by  thickening  of  the  shell  from  the  inside.

Although  the  perfect  and  the  deeply  eroded  shells  were  in  one  lot  when 
received,  yet  I  have  no  doubt  that  they  came  from  two  sources,  one  of  pure 
water,  the  other  carrying  CO2,  doubtless  from  leaching  through  decaying 
organic  matter. 

LYMN/EA  PICTONICA  Rochebrune  et  Mabille. 

Limncea  pictonica  R.  et  M.,  Miss.  Sci.  Cap  Horn,  p.  21,  1889. 

A  small,  very  fragile  species,  with  exserted  spire  and  truncate  apex,  2  or 
3  convex,  rapidly  increasing  whorls  remaining.  There  is  a  very  narrow 
perforation. 

Length  6,  diam.  3  mm. 

Picton  Island,  in  the  southeastern  termination  of  the  Beagle  Channel. 

This  species  seems  to  be  decidedly  narrower  than  the  preceding.  It 
may  be  the  southern  terminal  member  of  the  series  of  short  Lymnaeas 
represented  in  the  Magellan  district  by  L.  patagonica  and  on  the  Rio  Chico, 
400  to  500  miles  farther  north,  by  L.  p.  riochicoensis.  It  is  quite  possible, 
however,  that  these  several  forms  may  prove  to  be  independent  shortened 
forms,  each  directly  related  to  more  normal  forms.

SECTION  UNDETERMINED. 
LYMN^EA  ANDEANA  sp.  nov. 

(Plate  XLVI0,  Figs.  4,  40.) 

The  shell  is  acuminate-oblong,  imperforate,  very  thin  and  fragile,  pale 
yellowish-corneous,  translucent.  Surface  dull,  smooth  to  the  eye  except 
on  the  last  part  of  the  last  whorl,  where  it  is  conspicuously  malleated. 
Under  the  microscope  the  dullness  is  seen  to  be  caused  by  extremely  fine 
hair-lines,  mainly  longitudinal  in  direction,  but  forming  a  close  mesh  over 
the  whole  surface.  There  are  also  faint  growth-lines  and  weak  traces  of 
spiral  bands  of  vertical  wrinkles.  Whorls  barely  4,  the  first  convex,  those 
following  only  weakly  so.  The  last  whorl  has  the  form  of  a  long  ellipse. 
Aperture  ovate.  Parietal  film  scarcely  perceptible.  Columella  slender, 
slightly  concave,  dilated  above,  the  dilatation  thin  and  adnate. 

Length  11.9,  diam.  6.3  mm.;  aperture  7.3  mm.  long. 

Near  the  base  of  the  Andes  in  drying  pools  on  a  high  divide,  50  miles 
north  of  the  Rio  Chico. 

This  species  is  apparently  related  to  L.  peregrina  Clessin  of  southern 
Brazil  and  Uruguay,  but  differs  conspicuously  by  the  very  weak  develop- 
ment of  spiral  sculpture,  that  species  being  even  more  copiously  striate 
spirally  than  the  North  American  L.  colmnella. 

A  few  immature  specimens  of  another  thin,  fragile  species,  probably 
related  to  L.  andeana,  were  taken  in  small  streams  on  the  Rio  Chico,  10 
and  25  miles  above  the  Sierra  Oveja.

half  whorl  of  the  embryo,  which  is  tilted  up,  as  shown  in  fig.  5.  Growth 
of  the  shell  seems  to  be  upward  at  first,  the  nucleus  lying  below  the 
summit.  At  the  end  of  the  third  whorl,  in  C.  fulgttrata  and  several  other

species,  the  color-pattern  begins  weakly.  Previous  to  this  the  shell  is 
uniform  corneous-brown.  The  columellar  fold  is  present  at  a  very  early 
stage,  but  my  material  does  not  show  when  it  first  appears. 


532  PATAGONIAN    EXPEDITIONS  I     ZOOLOGY. 

The  growth  of  the  shell  in  Patagonian  species  is  periodic,  growth-arrest 
periods  being  marked  by  streaks  interrupting  the  normal  pattern.  On 
resumption  of  growth,  the  zigzag  pattern  is  sometimes  replaced  by  irregu- 
lar streaks  ;  but  in  a  later  growth-period  the  original  pattern  may  be 

resumed. 

The  subgenus  Pseudochilina  was  based  upon  a  form  shaped  about  like 
fig.  7  of  Plate  XLIII.  The  irregular  or  fibrous  surface,  which  served  to 
characterize  the  subgenus,  seems  to  me  to  be  wholly  due  to  erosion,  the 
cuticle  or  periostracum  being  lost  from  the  unique  type  in  the  National 
Museum.  In  other  characters  the  shell  is  a  typical  Chilina. 

Acyrogonia  of  Mabille  and  Rochebrune  is  a  Chilina  in  which  the  colu- 
mellar  plait  is  wanting.  I  have  found  this  plait  variable  in  development 
in  some  forms  of  Chilina  from  the  Rio  Chico.  In  C.  fulgurata  oligoptyx 
it  approaches  the  condition  described  in  Acyrogonia. 

DISTRIBUTION  OF  CHILINA. 

Chilina  occupies  the  temperate  and  cold  zones  of  South  America  from 
the  Tropic  of  Capricorn  to  Cape  Horn.  No  member  of  the  group,  either 
living  or  fossil,  has  been  found  outside  of  these  limits.1  It  is  noteworthy 
that  no  trace  of  the  group  has  been  found  in  other  Austral  lands --Tas- 
mania and  New  Zealand  having  sufficiently  similar  climatic  conditions  to 
favor  the  survival  of  Chilinidce,  if  the  family  ever  had  a  wider  range  in 
the  Antarctic  area. 

Within  their  area,  the  Chilinidcz  are  abundant  snails  in  all  suitable  sta- 
tions, as  Physidce  are  in  the  north.  They  swarm  in  springs,  small  streams, 
lakes,  and  in  some  places  the  margins  of  rivers.  They  are  most  abundant 
southward,  becoming  rarer  and  local  toward  the  northern  borders  of  their 
range. 

The  species  from  west  of  the  Andes  are  in  all  cases,  so  far  as  we  know, 
distinct  from  those  east  of  the  divide.  In  the  cold  temperate  and  cold 
zones  at  least,  the  widely  diverse  physical  features  on  opposite  sides  of 
the  Andes  would  lead  us  to  expect  different  snail  faunas. 

^Chilina  olivida  Repelin,  Ann.  Mus.  d'Hist.  Nat.  de  Marseille,  VII,  p.  69,  of  the  Cenomanian 
of  central  France,  has  no  columellar  fold,  and  is  clearly  a  Lymnseid  snail  with  no  relations  what- 
ever to  Chilina.  Chilina  in  Europe,  like  Partitla,  Polygyra,  Glandina,  etc.,  is  one  of  those  myths 
of  European  palaeontology  which  astonish  and  amuse  the  investigator  using  modern  methods  with 
Pulmonate  snails.

The  eastern  fauna,  with  which  alone  we  have  now  to  deal,1  inhabits  a 
comparatively  arid  region,  poorly  watered  by  roughly  parallel  streams 
flowing  southeastward  into  the  Atlantic.  Each  of  the  principal  river 
systems  has  its  own  series  of  freshwater  mollusks,  in  large  part  distinct 
specifically  or  racially  from  those  of  other  rivers.  The  Chilinidce  of  the  sev- 
eral drainages  have  been  enumerated  on  pp.  514-5.

This  species  is  the  type  of  the  group  Acyrogonia1  described  as  a  new  genus

the  general  shape  acutely  oval,  spire  projecting  but  not  very  slender ;  colu- 
mella arcuate,  twisted  but  little,  without  the  columellar  folds  characteristic 
of  Chilina,  and  descending  to  the  base  of  the  aperture." 

This  group  is  known  only  by  the  original  account.  Neither  of  the  two 
species  has  been  figured.  I  do  not  think  it  generically  distinct  from  Chilina. 
In  some  species  of  that  genus  the  columellar  fold  is  reduced  to  an  incon- 
spicuous vestige.

at  its  lower  third,  usually  hardly  visible  in  a  front  view.

Mount  of  Observation,  40  miles  south  of  Santa  Cruz  River. 

This  fine  species  was  collected  in  some  quantity.  It  is  distinguished 
from  Chilina  puelcha  d'Orb.  by  the  presence  of  a  parietal  fold,  among 
other  peculiarities.  No  other  species  from  south  of  the  Rio  de  La  Plata  drain- 
age has  this  fold  developed.  In  the  young  stages  (figs.  27,  28)  the  color- 
streaks  are  less  distinctly  defined,  fading  at  their  edges,1  and  the  parietal 
fold  is  present  only  as  a  very  thin  whitish  callus- 

CHILINA  SMITHI  sp.  nov. 

(Plate  XLIII,  Figs.  1-4.) 

The  shell  is  oblong-ovate,  solid,  minutely  rimate,  rather  rudely  sculp- 
tured, with  wrinkles  of  growth  and  more  or  less  distinct  spiral  lines ;  always 
more  or  less  deeply  eroded  in  the  adult  stage.  The  color  of  the  cuticle 
is  olive,  or  in  the  newly-formed  band  behind  the  outer  lip  it  is  yellow.  In 
adults  a  large  part  of  the  cuticle  is  wanting,  exposing  the  calcareous  layer 
beneath,  which  is  blue  and  gray,  or  when  deeply  worn  (as  in  figures  3  and 
4),  it  is  white.  The  spire  is  worn,  whorls  convex,  the  last  one  distinctly 
shoiddered,  compressed  laterally,  widest  at  the  middle  or  below  it.  The

less  dark  in  younger  shells,  fleshy-whitish  near  the  lip-edge,  which  is  thin 
and  acute.  The  columella  is  not  very  wide,  flat,  white  or  flesh-tinted, 
more  or  less  concave,  and  bears  a  rather  small,  very  oblique  fold  above.

Springs  on  the  Rio  Chico,  15-25  miles  above  the  Sierra  Oveja. 

This  is  one  of  the  largest  species  of  the  genus,  remarkable  for  its  solid, 
inornate  shell,  shouldered  at  the  last  whorl  (a  feature  not  very  well  shown 
in  the  figures),  and  very  dark  chestnut  or  purplish-chestnut  interior.  Typi- 
cally the  spire  is  well  produced,  as  in  figs,  i,  3,  but  the  lot  contains  also 
shortened  forms,  such  as  fig.  4. 

The  shouldered  last  whorl,  solidity  and  color  distinguish  this  species 
from  C.  parchappii  d'Orb.  It  also  attains  a  larger  size.  Named  in  honor 
of  Mr.  E.  A.  Smith,  to  whom  we  owe  a  very  useful  catalogue  of  the  genus. 

Young  shells  up  to  22  mm.  long  show  faint  traces  of  waved  longitudinal 
brown  streaks  on  the  last  whorl,  but  in  older  ones  these  disappear,  though 
faintly  indicated  spot-bands  may  persist  up  to  30  mm.  long  in  some 
examples.  Figures  8,  9,  10  of  Plate  XLIII  represent  young  shells  17.2, 
1 6  and  14.5  mm.  long  respectively.  At  this  stage  there  are  5^  to  6 
whorls.  The  spire  is  acuminate  and  the  apex  perfect  in  some  individuals. 
On  a  yellow  ground  there  are  chestnut  streaks,  which  show  three  (figs.  8, 
9)  or  four  (fig.  10)  forwardly  projecting  angles,  with  a  row  of  spots  just 

below  the  suture.1

CHILINA  FULGURATA  sp.  nov. 

(Plates  XLIII,  Figs.  11-15  ;  XLIII*,  Fig.  4.) 

The  shell  is  imperforate,  elliptical,  with  short,  conic  spire,  thin.  Fully 
grown  shells  are  in  large  part  dull  gray  from  loss  of  the  cuticle  on  the 
back,  but  what  remains  in  front  is  dull  pale  yellowish,  with  numerous 
dusky  brown,  angular  streaks  (fig.  15).  Younger  shells  (fig.  1 1,  length  12 
mm.,  and  fig.  12,  length  13.2  mm.)  are  densely  marked  with  reddish-chest- 
nut, zigzag  stripes  on  a  whitish  or  in  places  yellow  ground,  the  penultimate 
whorl  with  a  blue  ground.  In  an  older  stage  (figs.  13,  14,  length  16  mm.) 
the  ground  color  on  the  back  and  spire  is  blue,  but  whitish  at  the  base. 
The  brown  stripes  have  four  forwardly  projecting  angles.  The  apices  are 
more  or  less  eroded  in  the  type  lot,  but  there  are  evidently  not  less  than 
5  whorls.  The  aperture  shows  the  external  marking  on  a  ground  more 
or  less  suffused  with  rich  light  chestnut  in  shells  not  fully  adult,  but  in 
old  shells  the  markings  are  not  seen,  and  the  throat  becomes  chestnut, 
fading  to  whitish  near  the  lip.  The  columella  is  rather  narrow,  white, 
straight,  or  only  slightly  arcuate,  and  bears  a  small  and  rather  thin,  very 
oblique  lamella  above.1

Small  stream  on  the  Rio  Chico,  5  miles  above  the  Sierra  Oveja,  type 
locality ;  also  northward  to  the  foothills  of  the  Andes,  in  various  springs 
and  streams. 

This  species  has  the  elaborate  color-pattern  of  Chilina  puelcha 
d'Orbigny,  but  differs  from  that  by  its  comparatively  narrow  contour.  The 
dimensions  of  the  type  of  C.  puelcha  are,  length  20,  diam.  15  mm.  C. 
fnlgurata  is  probably  related  more  closely  to  C.  parchappii  d'Orb.,  a 
more  slender  and  lengthened  species,  deficient  in  color-ornamentation. 

The  type  of  C.  fnlgurata  is  drawn  in  Plate  XLIII,  figs.  13,  14,  and 
Plate  XLIIIrt,  fig.  4. 

In  springs  twenty-five  miles  above  the  Sierra  Oveja,  a  large,  thin  form 
of  fulgurata  was  found.  The  elaborate  color-pattern  persists  through 
the  period  of  maturity,  but  fails  in  the  aged  or  gerontic  stage.  The  sur- 
face has  minute  axial  plicae  and  distinct  spiral  lines,  giving  it  a  decussate-

granular  appearance,  more  or  less  developed  in  different  examples.  The 
columella  is  flat,  vertical,  nearly  straight,  with  a  small,  compressed  and 
acute  fold  above.  PI.  XLIIIa,  figs.  6,  6a,  represent  an"old  shell  deeply 
eroded  in  places.  Length  18  (spire  largely  eroded),  diam.  11,  length  of 
aperture  13  mm.  In  this  lot  the  cuticle  persists  over  most  of  the  surface. 

At  30  miles  above  the  Sierra  Oveja  similar  large  shells  were  found  in  a 
spring.  In  even  the  largest,  the  color-pattern  and  sculpture  persist  to 
the  lip-edge.  PI.  XLIIIA,  fig.  7,  represents  an  area  immediately  below  the 
termination  of  the  suture.  The  shell  measures,  length  20.7,  diam.  11, 
length  of  aperture  13.4  mm.  The  apex  is  eroded. 

In  a  small  running  stream  on  the  south  side  of  the  Rio  Chico,  25  miles 
above  Sierra  Oveja,  two  forms  of  Chilina  were  found :  numerous  small  C. 
fiilgurata,  the  largest  10  to  n  mm.  long,  and  probably  not  fully  adult; 
and  three  examples  of  a  very  elongate  form,  one  of  them  figured  in  PI. 
XLIV,  fig.  23.  In  this  shell  the  waved  streaks  appear  only  on  the  last 
half  of  the  last  whorl,  being  preceded  by  two  bands  of  small  spots. x  The 
columella  is  Lymnaeid.  Sculpture  as  in  the  large  decussate  C.  fiilgurata. 
Axis  rimate.  Length  17,  diam.  8,  length  of  aperture  10  mm.  The  sig-

Small  specimens  which  seem  to  be  C.  fulgurata  were  taken  in  a  spring 
on  the  south  side  of  the  Rio  Chico,  seven  miles  above  the  Sierra  Ventana. 

CHILINA  FULGURATA  OLIGOPTYX  subsp.  nov. 

(Plate  XLIV,  Figs.  18,  iSa,  20-22^.) 

The  shell  is  oval,  inflated,  with  short  but  acuminate  spire  of  between 
5  and  6  whorls.  The  cuticle  is  extremely  thin  and  deciduous,  but  more 
or  less  usually  remains  on  the  face  and  behind  the  outer  lip.  It  is  corneous, 
or  slightly  yellowish  (somewhat  too  yellow  in  figs.  20,  21,  22),  with  faint 
reddish-brown  streaks.  Where  the  epidermis  is  removed,  the  shell  is  ash 
colored,  or  livid  purplish  or  fleshy,  sometimes  showing  traces  of  the  waved 
color-markings,  the  spire  often  dark  purple  (as  in  fig.  22*2).  The  colu- 
mella is  only  moderately  arched,  and  either  has  no  fold  (fig.  18)  or  a 
small  fold  may  be  seen  above,  in  an  oblique  view,  sometimes  somewhat 
stronger  than  in  fig.  22.  The  outer  lip  is  somewhat  thickened  within, 
in  adult  shells. 

1  The  scattered  dots  shown  in  fig.  23  are  ferrous  deposits,  foreign  to  the  shell.

By  its  shorter  form,  weak  or  wanting  columellar  fold,  and  the  less  devel- 
oped color-pattern,  this  race  differs  from  C.  fulgurata.  Some  examples 
from  25  miles  below  the  Sierra  Ventana  are  more  fully  colored,  resembling 
C.  fulguvata  in  this  respect ;  and  it  may  be  said  that  dead  shells  which 
retain  the  cuticle  also  show  the  color-pattern  more  distinctly  than  living 

shells. 

CHILINA  FULGURATA  LIVIDA  subsp.  nov. 

(Plates  XLIII,  Figs.  5-7  ;  XLIV,  Figs.  16,  17,  19.) 

The  spire  is  longer  than  \n  fulgurata,  acuminate,  and  consisting  of  fully 
6X  whorls  ;  spiral  strise  distinct.  In  the  adult  stage  the  surface,  where 
unworn,  is  livid  purplish  on  the  back,  and  color-streaks  are  wanting  or 
very  weak,  though  one  to  three  faint  spot-bands  are  generally  retained. 
The  eroded  spots  have  the  appearance  of  mould,  the  edges  under  a 
hand-lens,  appearing  fuzzy  or  fibrous.  The  columellar  fold  is  usually  well 
developed,  though  often  appearing  weak  or  blunt  in  a  face  view.  The 
interior  is  dark  purplish-brown.

CHILINA  FULGURATA  ANDICOLA  subsp.  nov. 

(Plate  XLIII«,  Figs.  5,  50.) 

A  series  of  three  quite  young  shells  from  under  stones  along  a  small 
running  stream  near  the  mouth  of  the  Rio  Belgrano,  and  a  single  shell, 
perhaps  adult,  from  a  spring  50  miles  north  of  the  Rio  Chico,  at  an  ele- 
vation of  1750  ft.,  indicate  that  a  special  race  inhabits  the  Andean  foot- 
hills, though  the  material  at  hand  is  hardly  sufficient  for  its  full  charac- 
terization. The  cuticle  is  rather  bright  yellow,  with  a  full  development  of 
the  fidgurata  pattern  in  young  shells.  This  pattern  begins  about  the 
middle  of  the  third  whorl. 

In  the  larger  shell  (PI.  XLIIL?,  figs.  5,  5*2),  from  the  second  locality,  the 
ground  is  olive  or  greenish-yellow.  The  first  half  of  the  last  whorl  has 
the  usual  fulgurata  streaks,  but  the  last  half  (following  a  growth-arrest 
period)  has  the  streaks  broken,  leaving  four  spot-bands.  The  yellow 
ground  also  has  many  fine  olive  lines.  The  aperture  is  like  that  of 
fulgurata.  The  apex  is  eroded.  Length  8.5,  diam.  5,  length  of  aperture 
6.8  mm. 

CHILINA  FULGURATA  HATCHERI  subsp.  nov.

The  shell  is  thin,  of  a  dilute  dull  red  color,  variegated  with  four  bands 
of  spots,  more  or  less  indistinct,  often  hardly  noticeable.  There  are  also 
some  obscure  red-brown  longitudinal'  streaks.  The  spire  is  darker, 
acuminate  above,  its  surface  more  or  less  eroded.  There  would  be  over 
5  whorls  if  the  apex  were  perfect.  Surface  glossy,  with  fine  growth-lines 
and  very  delicate  spiral  striae,  much  as  in  C.  f^llg^^rata  from  30  miles  above

Arroyo  Eke,  near  the  headwaters  of  Spring  Creek  (north  of  the  Rio 
Belgrano),  April  10,  1898. 

Except  on  the  spire,  the  cuticle  is  generally  well  preserved.  When 
worn  on  the  last  whorl,  it  is  deciduous  along  the  spiral  striae,  which  other- 
wise are  hardly  noticeable.  These  shells  are  readily  distinguishable  from 
any  taken  at  lower  levels,  along  the  Rio  Chico. 

CHILINA  CAMPYLAXIS  sp.  nov. 

(Plate  XLIIIa,  Figs.  i-2a.) 

The  shell  is  oval,  much  inflated,  thin.  Dead  individuals,  but  evidently 
almost  or  wholly  unchanged  in  color,  are  light  reddish-brown,  with  rather 
faint  streaks  of  chestnut,  which  are  angular  and  dilated  to  form  three  bands 
of  sagittiform  spots  besides  a  row  of  small  spots  below  the  suture.  These 
markings  are  often  less  fully  developed  than  in  the  figured  specimens,  and 
they  are  generally  removed  in  part  by  the  erosion  of  the  surface.  Where 
the  cuticle  is  retained  behind  the  outer  lip,  it  is  yellow.  The  surface 
shows  spiral  striae  more  distinct  than  usual.  The  aperture  is  light  brown 
or  fulvous  inside.  The  outer  lip  does  not  seem  to  be  thickened  within,  as 
it  is  in  C.  f.  oligoptyx.  The  columella  is  narrow,  deeply  concave,  and  has 
a  small  but  distinct  fold  above  (rarely  subobsolete.)

The  numerous  specimens  vary  but  slightly  in  size  or  other  features. 
They  have  some  resemblance  to  the  Magellanic  C.  patagonica,  which 
however  is  figured  as  having  a  straight  columella  and  a  stronger  colu- 
mellar  fold. 

All  of  the  specimens  are  "dead"  shells.  At  this  spring  C.  fulgurata 
oligoptyx  was  also  found,  both  alive  and  among  the  dead  shells  which 
were  preserved  separately  ;  the  larger  individuals  have  the  outer  lip 
noticeably  thickened.  The  shells  of  C.  campylaxis  differ  constantly  from 
the  associated  oligoptyx  in  various  structural  features,  and  must,  I  think, 
be  regarded  as  specifically  diverse.

Chilina  monticola  Strebel,   Zool.  Jahrb.,  XXV,  1907,  p.  169,  Taf.  8,  fig. 

101. 

The  shell  is  thin  but  rather  strong,  translucent  chestnut,  with  separated, 
dilute,  waved  streaks,  or  spot  bands  also,  mostly  indistinct ;  comparatively 
broad,  with  short,  acute  spire  of  about  5  whorls.  Columella  has  a  very 
weak  fold,  not  visible  in  front  view. 

Length  9.8,  diam.  6.9,  aperture  8.4  X  3-9  mm.

Punta  Arenas,  in  a  large  mountain  lake  at  an  elevation  of  about  300 
meters. 

Strebel  seems  to  entertain  some  doubt  as  to  whether  this  may  not  be 
an  immature  stage  of  C.  ovalis  Sowerby.  I  have  not  seen  specimens. 

CHILINA  MONTICOLA  PILULA  subsp.  nov. 

(Plate  XLIV,  Figs.  29,  30,  300.) 

The  shell  is  very  small,  shortly  oval,  with  a  very  short  conic  spire  ; 
thin ;  glossy  when  unworn,  sculptured  with  fine  growth-striae  and  indis- 
tinct, minute  spiral  lines.  Adult  shells  are  generally  dull  ashy-  or  brown- 
ish-white from  loss  of  the  cuticle,  but  where  preserved,  it  is  yellow  or 
dusky  reddish,  closely  marked  with  indistinct  reddish-brown  streaks,  upon 
which  there  are  spots  at  intervals,  forming  five  spiral  bands,  one  just 
below  the  suture,  the  others  at  subequal  intervals  on  the  last  whorl.  The 
longitudinal  streaks  are  scarcely  visible  on  some  examples,  and  the  spot- 
bands  are  often  very  faint  or  reduced  to  three.  The  very  short  spire  is  eroded 
in  all  the  specimens  seen,  the  number  of  whorls  being  therefore  uncer- 
tain. The  aperture  is  quite  ample  and  shows  the  external  color  through 
the  thin  outer  lip.  The  columella  is  white,  rather  narrow  and  weakly

Springs  on  the  Rio  Chico,  25  miles  below  the  Sierra  Ventana,  Feb.  15, 

1899- 

This  species  is  known  from  40  specimens  in  two  lots,  taken  the  same 
day  in  the  same  neighborhood,  but  apparently  from  two  springs,  the  sta- 
tion numbers  being  different  and  the  condition  of  the  specimens  as 
regards  erosion  slightly  diverse.  There  is  also  another  individual  from  a 
different  station,  "freshwater  spring  on  the  Rio  Chico,"  date  and  locality 
not  given.  They  range  in  size  from  young  shells  less  than  3  mm.  long 
to  slightly  over  5  mm.  In  a  shell  of  3  mm.  there  are  fully  three  whorls. 
All  the  adults  have  the  spire  worn,  so  that  the  number  of  whorls  is  un- 
certain, but  there  are  evidently  four  or  more. 

The  very  globose  shape  of  these  shells  shows  that  they  are  not  young 
or  dwarf  individuals  of  the  larger  species  of  the  same  region.  Moreover, 
the  larger  ones  have  the  eroded  and  old  appearance  of  adult  snails. 
Whether  the  species  attains  greater  size  in  the  streams  running  from  the 
springs  which  they  inhabit  remains  uncertain.  I  know  of  several  instances 
of  dwarf  snails  inhabiting  springs,  having  put  at  least  one  such  case  on 
record.1  It  is  evident  that  the  usual  explanations  of  dwarfing  in  small 
quantities  of  water  are  not  pertinent,  since  in  flowing  springs  there  is  no 
lack  of  aeration  and  no  accumulation  of  the  toxines  of  metabolism.  It 
seems  likely  that  the  dwarfing  of  snails  in  springs  may  be  due  to  the 
purity  of  the  water,  which  affords  an  insufficient  supply  of  diatoms,  other 
algae  and  vegetable  food. 

This  form  is,  for  the  time  being,  ranked  as  a  subspecies  of  Chilina  monti- 
cola  from  Punta  Arenas,  but  I  suspect  that  it  is  related  rather  to  C.  ftilgu- 
rata.  Apparently  adult  shells  are  only  about  half  the  size  of  monticola.

A  short-oval,  inflated  shell,  with  usually  olive  ground-color,  but  some- 
times olive-yellow  or  bright  green,  and  either  unicolored  or  marked  with 
one  to  five  spiral  bands  of  dark  chestnut  spots,  alternating  with  spots  paler 
than  the  ground-color.  The  upper  bands  are  more  persistent  than  those 
below.  Very  rarely  the  pattern  is  of  irregularly  zigzag  streaks  flowing 
from  the  suture  down,  not  quite  reaching  the  base  (fig.  38).  The  ample 
aperture  is  blue-white  within,  and  usually  shows  the  external  markings 
through.  The  columellar  lamella  is  very  strong,  and  a  long  entering  callous 
ridge  stands  on  the  parietal  wall,  and  is  always  well  developed  in  adult 
snails.  The  specimens  figured  from  San  Gabriel's  Island,  opposite 
Colonia,  Uruguay,  measure :

long.  It  is  straw  yellow,  with  traces  of  a  spot-band  upon  a  low  spiral 
angle,  which  crowns  the  last  whorl.  It  is  also  stained  with  iron  oxide  in 
front  and  under  the  parietal  callus.  The  very  heavy  columellar  callus 
continues  upon  the  parietal  wall,  bearing  thick,  obtuse,  parietal  and  colu- 
mellar lamellae. 

This  species  is  chiefly  distinguished  from  C.  fluminea  by  its  very  heavy 
parietal  callus.

This  family  of  minute  river-snails  has  been  but  little  studied  or  col- 
lected in  South  America.  We  have  some  knowledge  of  the  species  of 
the  Rio  de  La  Plata  system  though  the  work  of  d'Orbigny,  Doering  and 
Strobel  and  collections  made  by  Dr.  W.  H.  Rush,  U.S.N.  In  south- 
ern Brazil  Dr.  von  Ihering  has  done  good  work,  though  hampered  by 
the  want  of  La  Platan  material  for  comparison.  In  Ecuador  K.  Miller 
has  described  a  few  forms  collected  by  Wolf  and  others.  In  the  north, 
Dr.  von  Martens  has  recorded  a  few  Venezuelan  species.  None  are 
known  from  the  Orinoco  or  Amazon  systems.  Through  the  collections  of 
Mr.  Hatcher  we  are  now  enabled  to  add  several  forms  from  Patagonia. 
The  opportunity  has  also  been  taken  fully  to  describe  and  figure  the 
known  species  of  Potamolithus,  part  of  them  new  forms,  most  of  the  rest 
hitherto  defined  only  by  a  brief  "key"  published  in  1892.  Only  six  of 
the  thirty  species  now  known  have  hitherto  been  figured. 

All  of  the  South  American  genera  and  species  of  Amnicolidce  are  de- 
scribed or  referred  to  below. 

The  following  genera  of  this  family  are  represented  in  South  America : 

Amnicola  Gould  and  Haldeman,         Idiopyrgus  Pilsbry, 
Littoridina  Souleyet,  Potamolitkus  Pilsbry, 

Potamopyrgus  Stimpson,  Lithococcus  Pilsbry. 

Of  these  genera,  Amnicola  has  been  found  only  in  the  extreme  north. 
A.  ernesti  (Martens)  of  Lake  Valencia,  Venezuela,  is  closely  related  to 
A.  panamensis  Tryon  and  several  Mexican  species,  and  is  undoubtedly 
of  North  American  origin. * 

Potamopyrgus  is  the  dominant  genus  of  Amnicolidce  in  New  Zealand 
and  Tasmania.  It  is  unknown  in  the  Oriental  region.  In  America  it 
extends  from  Argentina  to  Venezuela,  through  Mexico  to  central  Texas 
and  throughout  the  West  Indies.  This  distribution  is  explicable  on  the

supposition  that  the  genus  had  its  origin  in  Antarctica,  or  one  of  the 
Austral  lands  once  connected  therewith. 

Littoridina  resembles  the  Holarctic  Pahidestrina  and  the  genus  Flumo- 
pitpa *  of  Australia  and  the  Melanesian  Plateau,  but  until  the  external 
genitalia  of  all  can  be  compared,  no  well-founded  opinion  of  the  affinities 
of  these  genera  can  be  formed. 

Idiopyrgns  is  an  Archhelenic  genus,  if  my  estimate  of  its  affinities  is 
correct. 

The  affinities  fAIMkococcus  are  uncertain. 

Potamolithus,  in  the  form  of  the  shell,  closely  resembles  the  genera 
assembled  by  Tryon  in  the  subfamily  Lithoglyphina :  Fluminicola  of 
western  North  America,  Lithoglyphus  of  eastern  Europe,  Pachydrobia, 
Lacunopsis  and  Julliema  of  Indo-China.  All  of  these  genera  differ  from 
Potamolitlins  by  the  small  number  and  large  size  of  the  cusps  of  the  outer 
marginal  teeth.2  Fluminicola  has  male  genitalia  of  widely  different  form. 
The  genus  Petterdiana  of  Tasmania  and  Australia  has  a  strong  globular

from  them  in  dentition.

radula  resembles  that  of  Potamolithus  in  the  important  character  of  having 
many  minute  cusps  on  the  marginal  teeth,  more  than  double  the  number 
of  those  on  the  admedian  tooth.  It  differs  from  Potamolithus  by  having 
a  single  basal  cusp  or  denticle  on  each  side  of  the  central  tooth,  Potamo- 
lithus having  two  or  more.  I  have  found  the  number  of  basal  cusps  so 
variable  in  many  genera  that  I  do  not  attach  much  importance  to  this 
character.  Of  all  known  genera,  Petterdiana  is,  in  my  opinion,  the  most 
closely  related  to  Potamolittms. 

Marginal  teeth  with  a  small  number  of  cusps  characterize  the  subfamily 
IMhoglyphina.  The  Austral  genera  Potamolithus  and  Petterdiana  cannot 
be  included  in  this  subfamily.  They  may  for  the  present  be  placed  in  the 
Amnicolince.

than  half  as  long  as  the  shell ;  peristome  thin  and  simple,  continuous  or 
interrupted.  The  operculum  is  thin,  ovate,  paucispiral,  the  nucleus  below 
the  lower  third  and  near  the  columellar  margin.  The  long  penis  has 
several  digitate  lateral  papillae  or  simple  warts,  and  is  curved  at  the  end. 
The  central  tooth  of  the  radula  has  one  to  four  basal  denticles  on  each 
side.  The  marginal  teeth  have  very  numerous  denticles,  more  than  twice

DENTITION  OF  LITTORIDINA. 

Littoridina  guadichaudii,  the  type  of  the  genus,  has  several,  probably 
four,  basal  denticles  on  each  side  of  the  central  tooth.  Souleyet's  figure 
shows  five,  but  allowance  must  be  made  for  the  difficulty  of  the  object  and 
the  date,  1852. 

Dr.  von  Ihering  found  two  basal  denticles  on  each  side  in  L.  australis.

a  shell  resembling  Paludestrina  or  Bythinella,  but  differing  by  the  penis, 
which  is  not  bifid,  and  has  several  lateral  papillae  or  warts. 

We  owe  to  Souleyet  an  excellent  account  of  the  anatomy  of  L.  guadi- 
chaudii,  and  Dr.  von  Ihering  has  published  valuable  notes  on  that  of 
several  species  of  southern  Brazil.  Many  other  species  are  referred  to 
Littoridina  from  the  resemblance  of  the  shells  and  their  distribution  alone. 
Most  of  them  have  been  described  under  genera  based  upon  European 
types,  such  as  Paludestrina  and  Hydrobia,  which,  so  far  as  we  know,  differ 
anatomically  from  the  type  of  Littoridina.  Provisionally,  therefore,  we 
refer  to  Littoridina  all  of  the  smooth,  slender  and  thin  oviparous  Amni- 
colinae  of  South  America,  having  the  lip  simple. 

Most  of  the  species  are  fresh-water  forms,  but  a  few  live  as  well  in  the 
brackish  water  of  estuaries,  or  even  in  the  salt  water  of  sheltered  bays. 
They  are  known  to  extend  from  below  the  mouth  of  Santa  Cruz  River  in 
Patagonia  north  to  Ecuador  in  the  west,  and  to  the  state  of  Rio  Janeiro, 
Brazil,  in  the  east. 

Many  species  of  Littoridina  have  been  described  from  the  La  Plata  sys- 
tem and  the  Sierras  of  western  Argentina  (Provinces  of  Cordoba  and  Men- 
doza)  by  d'Orbigny,1  Strobel2  and  Doering,3  but  none  have  heretofore  been 
reported  from  the  southern  territories.  Mr.  Hatcher's  collections  extend 
the  range  of  the  genus  south  to  the  Mount  of  Observation,  below  the 
mouth  of  the  Santa  Cruz  River. 

Several  species  of  Littoridina  have  both  slender  and  stouter  forms, 
with  others  of  intermediate  shape,  in  any  large  lot.  These  differences 
may  be  sexual,  but  no  observations  bearing  on  the  point  have  been  made. 
In  some  other  species  the  contour  is  nearly  uniform. 

Various  authors  having  referred  the  Littoridinas  to  d'Orbigny's  Palu- 
destrina, it  may  be  well  to  give  some  account  of  that  genus. 

Paludestrina  was  proposed  by  A.  d'Orbigny  in  i8394  f°r  Paludina 
acuta  of  France  and  the  South  American  rissoids  of  fresh  and  brackish 
water,  having  the  operculum  spiral,  such  as  P.  lapidum,  P.  peristomata  and 
P.  australis.  Various  subsequent  authors  have  mentioned  or  discussed

the  group,  but  no  type  species  seems  to  have  been  selected  until  William 
Stimpson,  in  1865,  selected  P.  auberiana  d'Orb.  as  type.1  Bourguignat 
in  January,  1887,  named  P.  acuta  Drap.  as  type  of  the  genus.2  In  1895 
Dr.  von  Ihering  proposed  to  restrict  Paludestrina  to  the  group  now  called 
Potamolithus,  with  P.  peristomata  as  type.3  This  course  cannot  be  fol- 
lowed because  of  Bourguignat's  earlier  selection.  P.  acuta  (Drap.)  must 
stand  as  the  type  of  Paludestrina. 

The  following  names  will  fall  as  synonyms  of  Paludestrina :  Littori- 
nella  Braun,  1846,  type  L.  acuta  (Drap.).  Ecrobia  Stimpson,  1865,  type 
Turbo  minutus  Totten.  The  preceding  live  in  brackish  water,  or  in 
sheltered  bays  or  estuaries,  or  sometimes  where  the  water  is  fresh. 
The  exclusively  fresh- water  groups  Bythinella  Moq.,  1851,  type  B.  mridis 
Moq.,  and  Stimpsonia  Clessin,  i8y8,4  type  B.  nickliniana  (Lea),  are  in- 
distinguishable from  Paludestrina  in  shell,  operculum  and  dentition,  but 
according  to  Moquin-Tandon  the  penis  of  B.  ferrusma  is  bifid,  while 
that  of  P.  minuta  (Totten)  was  found  to  be  simple  by  Stimpson.  Until 
the  types  of  these  proposed  genera  are  studied  and  the  forms  of  their 
penes  ascertained,  there  seems  to  be  little  reason  for  recognizing  more 
than  one  genus  of  these  slender  Amnicoloid  snails  in  North  America  and 
Europe,  although  it  is  likely  that  several  may  ultimately  be  defined. 

In  Paludestrina  (including  Bythinella]  the  central  tooth  has  a  single 
well-developed  basal  denticle  on  each  side,  but  often  a  second  one  is 
weakly  developed.

The  shell  is  minute,  imperforate  (though  slightly  rimate),  rather  solid, 
olivaceous  brown,  smooth  ;  in  shape  ovate  or  somewhat  pupiform.  The 
outlines  of  the  spire  are  convex  ;  the  summit  minute,  a  little  obtuse, 
though  the  apex  is  not  depressed.  Whorls  4,  convex,  at  first  slowly,  then 
rapidly  widening,  the  suture  therefore  descends  more  rapidly  and 
obliquely  in  its  last  volution,  and  it  is  also  deeper  than  in  those  preceding.

This  selection  was  not  valid  for  the  reason  that  auberiana  was  not  one  of  the  species  included 
in  Paludestrina  in  d'Orbigny's  original  publication,  but  was  added  some  years  later.

The  last  whorl  is  rounded  and  expands  towards  the  aperture,  at  the  upper 
angle  of  which  it  descends  slightly.  The  aperture  is  subvertical,  sym- 
metrically ovate,  narrower  but  not  angular  above.  The  peristome  is  con- 
tinuous, of  a  deep  reddish  brown  color,  almost  black  at  the  edge.  The 
outer  margin  is  slightly  thickened  and  obtuse  ;  the  inner  margin  is  rather 
heavily  calloused,  forming  a  raised  ledge  across  the  preceding  whorl, 
from  which  it  is  slightly  detached  above  and  below.

Rio  Chico  de  la  Sta.  Cruz,  Territory  of  Santa  Cruz,  Argentina,  from 

below  the  mouth  of  the  Rio  Chalia  to  the  mouth  of  the  Rio  Belgrano  ; 
and  northward  along  the  eastern  slope  of  the  Andes  65  miles,  in  springs 
and  small  streams.  Specimens  were  taken  at  the  following  localities  : 
Spring  on  the  Rio  Chico  below  the  mouth  of  the  Rio  Chalia  (2  :  12  :  '99)  ; 
spring  on  Rio  Chico,  25  miles  below  Sierra  Ventana  (type  locality)  ; 
twenty  miles  below  Sierra  Ventana,  in  a  spring  ;  north  side  of  Rio  Chico 
near  Sierra  Ventana  ;  Rio  Chico,  40  miles  above  Sierra  Ventana  ;  small 
stream  5  miles  above  Sierra  Oveja  ;  small  stream  on  south  side  of  Rio 
Chico,  50  miles  above  Sierra  Oveja  ;  near  the  mouth  of  Rio  Belgrano  ;  Rio 
Blanco,  base  of  the  Andes ;  spring  50  miles  north  of  Rio  Chico,  elevation 
1750  ft;  spring  near  base  of  the  Andes,  65  miles  north  of  the  Rio  Chico, 
elevation  2400  ft.  Also  several  lots  from  springs  on  the  Rio  Chico  with- 
out exact  location. 

This  small  snail  is  evidently  abundant  in  springs  and  small  streams 
along  the  whole  course  of  the  Rio  Chico  de  la  Sta.  Cruz.  It  is  apparently 
related  to  L.  kuesteri  and  especially  to  L.  k.  cordillercz  (Strobel),1  from  the 
Province  of  Mendoza,  but  differs  from  these  by  its  wider,  convexly  conic 
spire,  the  shape  of  L.  hatcJieri  being  rather  pupiform,  whereas  the  spire  is 
strictly  conic  in  L.  kuesteri  and  cordillerce. 

L.  hatcheri  varies  within  wide  limits  in  nearly  all  of  the  colonies  col- 
lected. This  variation  is  chiefly  ( i )  in  size,  nearly  every  lot  consisting  of 
both  large  and  small  individuals,  the  difference  being  greater  than  I  have 
ever  observed  in  North  American  Amnicolidce ;  and  (2)  in  the  degree 
of  descent,  lateral  deviation  or  uncoiling  of  the  last  whorl.  As  type  I 
have  selected  a  shell  nearly  normal  in  shape,  PI.  XLII,  figs.  7,  ja,  2.25

mm.  long.  Some  others  in  the  same  lot  are  smaller  and  more  pupiform, 
with  the  parietal  callus  barely  free  from  the  preceding  whorl,  as  in  fig.  8, 
length  1.7  mm.  The  entire  lot  from  the  type  locality  consists  of  shells 
which  do  not  depart  much  from  the  normal  Littoridina  contour. 

At  two  stations,  40  and  50  miles  above  the  Sierra  Oveja,  a  considerable 
proportion  of  the  shells  have  the  last  whorl  deeply  descending  to  the  aper- 
ture and  becoming  free,  or  partially  free  near  the  termination.  A  series 
from  40  miles  above  Sierra  Oveja  is  figured,  PI.  XLII,  figs,  n,  na,  12, 
13.  Fig.  12  represents  a  nearly  normal  shell;  figs,  n,  na  and  13, 
those  with  the  last  whorl  loosening  its  coil ;  all  are  fully  mature,  but  not 
old  snails.  The  individuals  figured  measure :

The  same  tendency  is  well-marked  in  a  lot  from  far  down  the  river, 
below  the  mouth  of  the  Rio  Chalia.  The  other  lots  of  the  species  resemble 
the  type  lot,  having  the  shape  nearly  normal,  but  with  a  variable  proportion 
of  individuals  in  which  the  peristome  is  partly  or  for  a  short  distance  free. 

L.  hatchen  is  thus  a  species  distinctly  aged  or  gerontic,  with  this  feature 
much  more  strongly  emphasized  in  certain  colonies. 

LITTORIDINA  SIMPLEX  sp.  nov. 

(Plate  XLII,  Figs.  9,  10.) 

The  shell  is  minutely  rimate  but  scarcely  perforate,  rather  thin,  ovate- 
conic,  of  a  very  pale  olivaceous-yellowish  tint,  the  apex  and  first  whorl 
reddish  in  the  type  lot,  smoothish,  but  lightly  marked  with  growth-lines. 
The  spire  is  straightly  conic,  the  apex  minute  and  very  slightly  obtuse. 
Whorls  4^ ,  all  rather  strongly  convex,  regularly  enlarging,  and  joined 
by  an  impressed  suture,  which  on  the  last  whorl  or  two  shows  a  narrow 
faint  margination  below  caused  by  transparence.  The  aperture  is  ovate, 
subvertical.  Peristome  continuous,  its  edge  delicately  marked  with  a 
brownish  line.  The  outer  lip  curves  forward  a  little  in  the  middle,  and 
has  a  very  delicate  whitish  thickening  within.  Inner  margin  thickened  a 
little,  continuous,  in  contact  with  the  preceding  whorl.

556  PATAGONIAN   EXPEDITIONS  I     ZOOLOGY. 

Springs  along  the  Rio  Chico  de  la  Sta.  Cruz,  at  the  following  places  : 
About  15-20  miles  above  the  mouth  of  the  Rio  Chalia;  springs  20  and 
25  miles  below  the  Sierra  Ventana ;  spring  near  the  Sierra  Ventana  (type 
locality) ;  25  and  50  miles  above  the  Sierra  Oveja.  Also  near  Mt.  of 
Observation,  on  the  coast,  below  the  mouth  of  the  Santa  Cruz  River. 
Also  at  the  foot  of  the  Andes,  50  miles  north  of  the  Rio  Chico. 

This  species  resembles  several  forms  of  the  Rio  de  La  Plata  system,  but 
is  distinguished  by  the  combination  of  quite  strongly  convex  whorls  and 
a  continuous  peristome ;  its  inner  margin,  though  not  much  thickened,  yet 
forms  a  distinct  ledge  across  the  preceding  whorl.  The  striation  is  exag- 
gerated in  fig.  9,  and  the  umbilical  chink  is  represented  too  wide  and 
prominent  in  both  figures.  The  apex  is  reddish  in  the  type  lot,  but  not 
in  others.  L.  simplex  occurs  in  the  same  springs  with  L.  hatcheri  along 
the  Rio  Chico,  but  it  is  apparently  less  abundant  and  it  does  not  seem  to 
ascend  the  river  so  far. 

LlTTORIDINA   SUBLINEATA  Sp.   nOV. 
(Plate  XLVItf,  Figs.  5,  $«.) 

The  shell  is  imperforate,  ovate-pyramidal,  thin,  light  brown.  Surface 
faintly  marked  with  growth-lines,  and  on  the  last  half  of  the  last  whorl 
there  are  several  (four  or  five  in  the  type  specimen)  very  low  spiral  cords, 
grouped  in  the  peripheral  region.  The  spire  is  rather  straightly  conic, 
the  summit  a  little  obtuse,  the  apex  rising  but  little  above  the  level  of  the 
first  whorl.  Whorls  5,  convex,  the  last  very  indistinctly  angular  below 
the  periphery,  causing  the  base  to  appear  slightly  flattened.  The  aperture 
is  ovate,  very  slightly  oblique;  peristome  thin  and  acute,  the  outer  margin 
not  darkened  or  thickened.  Columella  concave,  slightly  thickened,  con- 
tinued in  a  thin  adnate  callus  across  the  parietal  wall. 

Length  3.6,  diam.  2.2  mm.,  length  of  aperture  1.5  mm. 

Small  stream  on  the  Rio  Chico,  35  miles  above  the  Sierra  Oveja  (type 
locality) ;  also  in  a  spring  25  miles  above  the  Sierra  Oveja,  and  in  a  "big 
spring  on  the  Rio  Chico,"  the  exact  location  of  which  was  not  noted  on 
the  collector's  label. 

It  sometimes  attains  a  larger  size  than  the  type,  a  shell  from  the  second 
lot  noted  above  being  5.4  mm.  long  with  5^  whorls.  This  species  differs 
from  L.  simplex  by  its  weakly  subangular  periphery,  marked  with  a  few 
spiral  lines,  the  less  prominent  parietal  callus  and  fragile  outer  lip.

Length  8.3,  diam.  4,      length  of  aperture  3.5  mm.;  whorls  8. 

8.2       "      3.9        "  "        3.2     "          "       y#. 

8-4  3-9  "        3-3     "  8#. 

In  a  small  spring  back  of  the  Cerro,  Montevideo,  the  shells  are  similar 
but  smaller,  about  5  mm.  long  with  6%  whorls. 

Shells  from  Rio  Grande  do  Sul,  sent  by  Dr.  von  Ihering,  are  about  6 
mm.  long,  2.3  to  2.9  mm.  in  diameter.  The  more  slender  shells  are  less 
numerous  than  the  stouter  ones,  and  some  are  transitional  in  shape.  The 
color  varies  from  dark  to  pale  olive  (Plate  XLI<:,  figs.  3,  4,  8).  A  small 
form  has  been  sent  also  from  Ilha  Comprida,  near  Iguape,  on  the  Sao 
Paulo  littoral. 

Melania  dubiosa  Clessin,  judging  from  specimens  sent  from  S.  Leopoldo, 
State  of  Rio  Grande  do  Sul,  by  Dr.  von  Ihering,  is  identical  with  the 
large  form  of  L.  australis  noticed  above  from  Montevideo.

(Plate  XLIf,  Fig.  9.) 

The  shell  is  barely  perforate,  oblong-turrite,  pale  olivaceous,  the  length 
about  double  the  greatest  diameter,  and  two  and  one-half  times  the  length 
of  the  aperture.  Spire  rather  straightly  conic,  the  apex  obtuse.  Whorls

with  very  fine  spiral  striae,  usually  strongest  on  the  penultimate  whorl. 
The  aperture  is  ovate,  angular  above.  Peristome  thin  and  simple,  contin- 
uous, the  columellar  margin  narrowly  expanded.

Puerto  Bertoni,  Paraguay.  Types  No.  103,045,  A.  N.  S.  Phila.,  from  No. 
244  of  the  Museu  Paulista,  collected  by  A.  de  W.  Bertoni. 

This  species  differs  from  Potamopyrgus  peteningensis  (Gld.)  by  its  much 
less  convex  whorls,  smaller  size  and  minute  spiral  striae.  Potamopyrgus 
scottii  has  far  more  convex  whorls  and  coarser  sculpture. 

In  some  specimens  from  the  type  locality  the  spiral  striae  are  extremely 
minute  and  weak,  yet  visible  under  the  compound  microscope.  These 
were  sent  under  No.  190  Museu  Paulista. 

A  few  other  species  at  present  referred  to  Litioridina,  such  as  L.  pedrina 
Miller,  have  spiral  sculpture  ;  yet  the  presence  of  this  unusual  feature  raises 
some  doubt  as  to  the  genus,  which  can  be  definitely  determined  only  by 
examination  of  the  genitalia.  L.  bertoniana  may  prove  to  belong  to 
Potamopyrgus.

The  shell  is  very  minutely  perforate,  turrite,  the  length  about  double

spire  has  straight  outlines  and  an  obtuse  apex.  Whorls  6y2 ,  very  convex, 
parted  by  a  deep  suture.  The  first  two  whorls  are  smooth;  then  fine, 
narrow,  thread-like,  spiral  striae  appear,  6  to  8  in  number  on  the  visible 
part  of  each  whorl,  one  at  the  upper  third  sometimes  being  more  promi- 
nent. There  are  also  numerous  ripples  in  an  axial  direction,  on  the  last 
two  whorls.  The  last  whorl  is  well  rounded  and  nearly  smooth  on  the 
base.  The  aperture  is  ovate,  peristome  simple  and  thin,  continuous,  the 
columellar  margin  concave,  narrowly  reflexed.

This  is  a  very  much  lengthened  form,  larger  and  longer  than  P.  guara- 
niticus  (Doer.),  and  differs  in  sculpture.  It  is  closely  related  to  P.  peten- 
ingensis  (Gld.)  which,  however,  has  a  smooth  surface.  The  specimens 
are  bleached  and  apparently  fossil,  being  filled  with  sandy  mud.  A 
minute  embryonic  shell  was  obtained  from  the  matrix  washed  out  of  one 
of  the  specimens  figured.  This  confirms  the  generic  reference  to  some 
extent,  as  all  Potamopyrgus  species  are  viviparous.

8.5  mm.  long,  2.5  wide,  with  6  whorls.  One  of  the  original  lot  is  figured

(fig.  12).  It  measures  5.4  mm.  long,  2.4  wide,  the  aperture  1.8  mm.  long, 
and  is  composed  of  6^  whorls.  The  apex  is  very  obtuse.  Another  lot, 
received  from  G.  von  Frauenfeld,  contains  shells  slightly  more  slender 
than  that  figured.  In  one  of  them  I  found  two  minute  embryonic  shells. 

IDIOPYRGUS  gen.  nov. 

The  shell  is  perforate,  solid,  turrite,  with  long  spire  of  very  convex 
whorls  ;  aperture  diagonal,  oval,  its  plane  sloping  forward  below,  posterior 
end  rounded,  sinused  ;  a  small  sinus  at  junction  of  the  outer  lip  with  the 
basal  margin.  Lip  slightly  expanded,  thickened  within.  Operculum 
paucispiral,  with  the  nucleus  at  the  lower  fourth,  near  the  columellar 
margin.  Radula  having  the  formula  ^.  7.  9.  16. 

Type,  I.  souleyetianus. 

The  snail  for  which  this  genus  is  proposed  differs  from  all  known  species 
of  Littoridina  by  its  internally  thickened,  somewhat  expanded  and  bisinu- 
ate  peristome,  the  diagonal  aperture,  and  by  having  fewer  cusps  on  the 
upper  reflection  of  the  central  teeth,  as  well  as  on  the  marginal  teeth.  The 
scoop-like  shape  of  the  outer  marginal  tooth  is  also  rather  peculiar. 

FIG.  12. 


Idiopyrgus  souleyetianus,  half  row  of  teeth  and  an  isolated  marginal  tooth. 

Idiopyrgus  has  some  resemblance  to  the  Dalmatian  genus  Lanzaia 
Brusina,  and  to  the  Mexican  Pterides  Pilsbry.  In  all  of  them  the  long 
axis  of  the  aperture  stands  strongly  diagonal  to  that  of  the  shell,  the 
posterior  end  of  the  aperture  is  rounded,  effuse  or  sinused,  the  lip  ex- 
pands more  or  less,  and  the  whorls  of  the  tapering  spire  are  strongly 
convex.  These  apertural  characters  are  so  unusual  in  Amnicolidce,  that  I 
am  disposed  to  view  them  as  indications  of  real  relationship  between  the 
three  genera,  rather  than  convergent  structures  in  snails  otherwise  diverse. 


PILSBRY:   NON-MARINE  MOLLUSCA  OF  PATAGONIA.  565 

Unfortunately  Lanzaia  and  Pterides  are  known  by  dead  and  bleached 
shells  only,  so  that  the  relationship  suggested  remains  hypothetical.  It 
affords  no  safe  basis  for  deductions  concerning  the  antecedents  of  the  three 
groups,  each  known  from  a  single  spot,  and  separated  from  its  supposed 
relatives  by  thousands  of  miles. 

The  genera  are  characterized  as  follows  : 

Common  characters :  —  Shell  turrite,  composed  of  very  convex  whorls  ;  aperture  strongly 
diagonal  to  the  axis  of  the  shell,  oval,  the  posterior  end  rounded,  spreading  or  sinused, 
the  basal  margin  also  retracted  or  effuse ;  peristome  continuous,  more  or  less  expanding, 
running  forward  below. 

a.  Shell  openly  umbilicate,  thin,  sculptured  with  sinuous  longitudinal  ribs  and  fine  spiral 

stria,  minute  (2  to   3  mm.   long,  with  6  whorls) ;  the  aperture  elliptical,  lip  broadly 
flaring.     Dalmatia.  Lanzaia  Brusina. 

b.  Shell  rimate,  thin,  smooth,  minute  (2.5  to  3  mm.  long,  with  7  to  10  whorls)  ;  the  aperture 

ovate ;    lip  sinused  or  spreading  above,  broadly  retracted  or  spreading  at  the  base. 
Mexico.  Pterides  Pilsbry. 

c.  Shell  perforate,  solid,  smooth,  of  about  71^  whorls ;  the  aperture  oval,  small,  the  lip 

having  a  rounded  sinus  above  and  a  smaller  one  at  junction  of  outer  and  basal  margins, 
which  expand  but  little.     Southeastern  Brazil.  Idiopyrgus  Pilsbry. 

IDIOPYRGUS  SOULEYETIANUS  sp.  nov. 

(Plate  XLI<r,  Figs.  14,  140.) 

The  shell  is  perforate,  solid,  turrited,  greenish-yellow,  opaque.  The 
surface  is  smooth  and  glossy,  growth-lines  very  faint.  The  spire  tapers 
regularly  to  a  small  but  obtuse  apex.  Whorls  7^ ,  all  strongly  convex, 
joined  by  deep  sutures.  The  aperture  is  oval,  oblique,  the  basal  margin 
being  advanced,  the  outer  lip  retracting  upward.  The  peristome  is  con- 
tinuous, the  outer  lip  expanded,  somewhat  thickened  within.  It  has  a 
rounded  sinus  just  below  the  upper  insertion,  and  a  small  sinus  at  the  junc- 
tion of  the  outer  and  basal  margins.  The  continuous  columellar  and 
parietal  margins  are  arcuate,  forming  a  raised  ledge  across  the  parietal  wall. 

Length  5.3,  diam.  2.1  mm.,  length  of  aperture  with  peristome  1.9  mm. 

Rio  Doce,  State  of  Espirito  Santo,  Brazil.  Types  No.  100,534,  A.  N. 
S.  Phila.,  from  No.  127  Museu  Paulista. 

In  old  individuals  the  spire  becomes  more  or  less  shortened  by  erosion 
of  the  early  whorls.  This  form  differs  from  the  Littoridinas  by  its  peculiar 
peristome.  It  is  probably  a  straggler  from  the  fauna  of  eastern  Brazil,  of 
which  little  is  yet  known.

fied  as  P.  lapidum}-  In  this  form  "the  penis  is  inserted  nearly  on  the 
median  line  of  the  back  of  the  neck  (fig.  13).  It  was  not  found  for  a  long 
time,  because  the  number  of  females  far  exceeded  the  males  among  the 
animals  examined.  It  is  very  broad  at  the  base,  provided  with  an  obtuse 
hump  and  runs  somewhat  coiled  towards  the  right  side,  where  its  summit 
lies  near  the  base  of  the  tentacle.  It  is  perforated  throughout  by  the  vas 
deferens,  and  terminates  in  a  slender  conical  point,  which  is  encircled  by 
a  sort  of  prepuce." 

Dentition  of  Potamolithus.  —  I  have  examined  the  teeth  of  P.  rushii

narrow,  and  the  side  cusps  are  small.  The  cusps  of  the  admedian  tooth 
are  of  about  equal  width,  but  are  longer  in  the  middle,  as  shown  in  fig.

numerous,  and  on  the  outer. they  are  still  more  numerous.

longer  than  its  fellows.  All  of  the  teeth  have  the  same  general  shape  as

those  of  P.  rushii,  the  difference  in  the  figures  being  chiefly  due  to  the 
side  teeth  being  shown  in  their  natural  positions,  while  in  P.  rushii  they 
are  drawn  from  a  frayed  radula,  as  is  usually  done  in  allied  genera. 

The  teeth  of  a  form  from  the  Santa  Maria  River,  a  tributary  of  the

each  side.  The  figure  is  somewhat  diagrammatic,  but  shows  teeth  re-

The  eggs  are  deposited  in  plano-convex  chitinous  capsules  about  .6 
or  .7  mm.  in  diameter,  adhering  to  shells  and  probably  stones.  The 
embryonic  shell  is  smooth,  Naticoid  or  globular  in  probably  all  of  the 
species.  So  far  as  I  can  see,  it  is  quite  continuous  with  the  neanic  stage. 
In  all  of  the  species  studied,  the  earlier  portion  of  the  neanic  stage  is  also 
Naticoid.  In  some  forms  this  shape  persists  to  maturity,  but  in  others 
angles  or  carinae  set  in,  their  appearance  dividing  the  period  of  youth  into 
two  or  three  substages ;  so  that  a  highly  specialized  form  may  pass  suc- 
cessively through  rounded,  singly  carinate,  bicarinate,  tricarinate,  and 
finally  varicose  stages.  The  degrees  to  which  these  sculpture-conditions 
are  accelerated  and  the  stage  finally  reached,  allow  us  to  fix  the  relation- 
ships and  evolutionary  grade  of  the  several  forms  with  some  degree  of 
accuracy,  in  species  where  the  young  stages  are  accessible. 

These  little  river  snails  live  on  and  under  stones,  at  and  below  low- 
water  mark,  often  in  copious  numbers.  Up  to  this  time,  they  have  been 
collected  at  comparatively  few  places,  yet  the  range  of  the  genus  probably 


PILSBRY:     NON-MARINE    MOLLUSCA    OF    PATAGONIA.  569 

embraces  the  whole  La  Plata  drainage,  together  with  some  rivers  flowing 
directly  into  the  Atlantic,  but  having  their  rise  adjacent  to  or  interposed 
between  the  head  streams  of  the  Uruguay  and  Parana  Rivers.  Many  new 
forms  doubtless  remain  to  be  found,  since  only  an  inconsiderable  part  of 
the  waters  of  the  Plata  system  have  been  explored  for  mollusks. 

To  what  extent  the  specific  characters  of  the  forms  vary  from  place  to 
place,  we  cannot  say,  since  most  of  them  are  known  from  a  single  locality. 
P.  lapidum,  which  has  been  assigned  a  wide  range,  seems  to  vary  with 
locality,  and  probably  several  species  will  eventually  be  recognized  in 
what  is  now  considered  lapidum.  Of  most  of  the  forms,  many  specimens 
have  been  studied,  some  of  them  by  hundreds,  and  I  have  been  astonished 
at  the  absence  of  intermediate  or  ambiguous  individuals,  such  as  one  finds 
in  the  fresh-water  Pleiiroceratidce  or  Meldniidce.  It  is  however  well  known 
to  those  who  have  studied  large  quantities  of  fresh-water  snails,  that  the 
Amnicolidce  are  generally  conservative ;  the  specific  features  are  crystal- 
lized, while  in  the  Melanians  they  are  fluid. 

SIGNIFICANCE  OF  THE  CHARACTERS  OF  POTAMOLITHUS. 

In  the  Amnicolidce,  as  in  the  Viviparidce,  the  prevalent  genera  almost 
everywhere  are  smooth-shelled  forms  with  rounded  or  convex  whorls. 
Such  forms  have  prevailed  since  the  first  appearance  of  these  families.  In 
those  Amnicolidce  which  are  sculptured  in  the  adult  stage,  the  early 
(embryonic  and  early  neanic)  stages  are  smooth  or  nearly  so.  These  facts 
apparently  point  to  the  conclusion  that  smooth,  rounded  shells  are  prim- 
itive and  sculptured  shells  derivative  in  these  families. 

Throughout  Neocene  time,  carinate,  varicose  or  otherwise  strongly 
sculptured  species  or  genera  of  these  families  have  frequently  appeared, 
but  their  distribution  has  been  local  and  their  duration  brief.  In  some 
cases  the  genesis  of  these  sculptured  or  distorted  forms  from  smooth  and 
normal  types  has  been  traced,  as  in  the  case  of  Viviparus  hoernesi  of  the 
Pliocene  of  southeastern  Europe,  and  Viviparus  altior  and  limnothauma  of 
the  Floridian  Pleistocene.  At  the  present  time,  sculptured  Viviparidce 
and  Amnicolidce  are  comparatively  rare  and  confined  to  small  areas. 
Margarya  in  Lake  Tali,  Tulotoma  in  the  Coosa  River,  Pyrgulopsis  in 
Pyramid  Lake,  Nevada,  and  Tryonia  in  a  very  restricted  area  in  the 
Southwest,  are  familiar  examples.  To  these  may  be  added  the  group  of 
carinate  species  of  Potamolithus  in  the  Uruguay  River.  In  all  of  these 


570  PATAGONIAN   EXPEDITIONS  :     ZOOLOGY. 

cases,  the  distribution  of  the  forms  is  very  restricted,  often  to  a  single  lake, 
or  a  few  springs;  and  in  some  cases,  as  Pyrgtdopsis  and  Tryonia,  we 
have  evidence  that  the  species  had  a  wider  range  in  the  Pleistocene  and 
are  now  apparently  approaching  extinction. 

The  facts  indicate  that  in  Amnicolidce  and  Viviparidce,  shell-sculpture 
is  a  phylogerontic  character,  showing  the  approach  of  senility  of  the  race ; 
strongly  developed  sculpture  in  a  species  signalizes  its  last  incarnation. 

The  considerations  advanced  above  go  to  show  that  the  present  Pota- 
molithus  fauna  consists  in  large  part  of  species  which  in  an  evolutionary 
sense  are  aged,  are  more  or  less  distinctly  gerontic  or  senile.  Over  80 
per  cent,  of  the  species  have  characteristics  which  indicate,  as  experience 
has  shown,  that  they  represent  side  lines  of  evolution,  impotent  to  continue 
the  phylum,  or  to  give  birth  to  new  phyla.  There  remains  also  a  small 
group  of  unspecialized  species  represented  by  P.  lapidwm  of  the  Parana 
and  its  allies  in  southern  Brazil. 

I  have  been  unable  to  find  a  shred  of  evidence  to  connect  the  develop- 
ment of  sculpture  in  these  fresh-water  snails  with  the  concentration  or 
increased  alkaline  content  of  waters  they  inhabit,  as  some  conchologists 
have  assumed.  It  is  doubtful  whether  any  such  modified  forms  inhabit 
alkaline  or  saline  waters,  while  it  is  positively  known  that  most  of  them 
do  not.  Amnicolidce  which  live  in  brackish  or  sea  water  are  not  strongly 
sculptured,  but  as  smooth  as  their  congeners  in  fresh  water.  Examples 
of  this  are  found  in  certain  species  of  Paludestrina  (P.  minuta  (Tott),  P. 
acuta  (Drap.),  P.  salsa  Pils.)  and  Littoridina  (L.  aitstmlis  (d'Orb.),  etc.). 
It  is  extremely  likely  that  these  are  forms  of  fresh-water  origin,  which  have 
become  adapted  secondarily  to  more  or  less  saline  waters.  Part  of  them 
live  also  in  perfectly  fresh  water. 

INTERRELATIONS  OF  THE  SPECIES  OF  POTAMOLITHUS. 

The  species  now  known  belong  to  four  collateral  phyla,  each  compris- 
ing forms  in  several  very  diverse  stages  of  specialization.  The  less  dif- 
ferentiated species  in  each  phylum  retain  in  adults  a  globular  or  Naticoid 
shell  without  keels  or  angles,  and  in  three  of  the  groups  have  the  lip 
simple  and  unspecialized.  This  type  of  shell  is  common  to  other  genera  of 
the  subfamily.  In  all  of  the  phyla  some  species  have  developed  ortho- 
genetically  a  varix  or  crest  at  the  lip ;  the  shape  of  the  shell  is  profoundly 
altered  by  spiral  keels  in  some  species.  These  modifications  are  more  or

less  exactly  parallel  in  the  several  series.  I  have  attempted  to  express 
the  above  ideas  graphically  in  the  following  diagram,  in  which  the  least 
evolved  species  of  each  group  are  placed  below,  while  the  carinate  forms

While  the  above  diagrams  are  not  intended  for  phylogenetic  trees,  all 
the  species  being  contemporaneous,  yet  it  is  likely  that  the  ancestral  forms 
in  groups  II,  III  and  IV  did  not  differ  materially  from  the  least  differ- 
entiated of  the  recent  species.  It  is  significant  that  the  only  form  known 
to  have  a  wide  distribution,  P.  lapidum,  is  one  of  the  least  specialized  of 
the  genus. 

The  evolution  of  carinae  and  varices  in  the  several  groups  seems  to  have 
been  homoplastic.  It  will  be  shown  below  that  the  keels  are  superposed

upon  the  Naticoid  form  much  earlier  in  some  species  than  in  others  ;  and 
judging  from  these  various  degrees  of  acceleration,  it  would  seem  that  the 
specialized  species  are  of  unequal  antiquity.

This  species  has  some  resemblance  to  P.  hidalgoi,  from  which  it  differs 
by  the  entirely  different  shape  of  the  aperture,  the  swelling  between  keel 
and  suture,  etc.  The  bisinuate  outer  lip,  the  texture  and  color-pattern  of 
the  shell,  etc.,  show  it  to  be  a  carinate  member  of  the  group  of  P.  bisinu- 
atus.  Described  and  figured  from  the  type  specimen.

The  shell  is  imperforate,  globose-conic,  rather  solid,  yellowish  olive, 
smooth  and  glossy,  faintly  marked  with  growth  lines.  The  spire  is  conic, 
truncate  at  the  summit  in  adult  shells  of  the  type  lot,  about  3^  moder- 
ately convex  whorls  remaining.  The  last  whorl  is  evenly  convex,  smooth, 
and  expands  strongly  at  the  lip.  There  is  a  narrow  umbilical  crescent. 
The  aperture  is  very  oblique  and  subcircular.  The  outer  lip  is  strongly 
expanded,  built  forward  and  convex  beyond  the  expansion,  and  then 
contracted,  with  three  deep  notches  in  its  margin,  one  near  the  upper 
insertion,  another  median,  the  third  wider  and  basal  in  position.  The 
columella  and  parietal  wall  are  moderately  calloused,  and  the  whole

Development. — The  neanic  stage  in  this  species  is  like  that  of  P. 
bisinuatus.  The  ephebic  stage  is  described  above.  A  single  gerontic 
individual  before  me  has  built  the  median  region  of  the  outer  lip  forward, 
obliterating  the  median  notch  of  the  lip  (PI.  XLI,  figs.  2,  2.0). 

This  remarkable  form  is  the  most  advanced  of  the  bisinuatus  phylum 
known.  It  resembles  P.  bisinuatus  in  contour,  and  neanic  shells  of  the 
two  species  are  distinguishable  only  by  the  bands  of  the  latter,  when  these 
are  developed.  The  ephebic  stage  differs  widely  by  the  strong  expansion 
of  the  outer  lip,  its  thickened  and  thrice  notched  face. 

What  relation  P.  bisinuatus  and  P.  sykesi  bear  towards  P.  petitianus 
(d'Orb.)  of  the  Parana  River  is  unknown,  pending  the  discovery  of  the  adult 
stage  of  the  latter,  the  specimen  described  and  figured  by  d'Orbigny  being 
supposed  to  be  immature.  It  is  likely  that  petitianus  will  prove  to  be 
different  from  either  of  the  other  species.

This  may  be  the  neanic  stage  of  a  species  allied  to  P.  bisinuatus ;  but 
in  this  group  of  forms  (bisinuatus  and  sykesi]  the  neanic  stage  shows  no 
specific  differentiation,  the  specific  characters  appearing  only  in  the  final 
stage  of  development.  Until  the  adult  form  of  P.  petitianus  is  collected 
at  the  type  locality,  San  Pedro  on  the  Parana,  no  good  purpose  will  be 
served  by  uniting  either  of  the  other  species  to  petitianus  as  its  hypotheti- 
cal adult.  There  remains  also  the  possibility  that  P.  petitiamis  is  a  per- 
manently undeveloped  form,  not  passing  beyond  the  neanic  stage  of  the 
bisinuate  species,  and  therefore  falling  more  properly  in  the  lapidum 
group.  Compare  also  P.  paranensis,  p.  589.

Potamolithus  bisinuatus  Pilsbry,  Nautilus,  X,  p.  88,  Dec.,  1896. 

The  shell  is  imperforate,  globose-conic,  moderately  solid,  green  or  pale 
yellowish-green,  sometimes  one-colored,  but  usually  begirt  with  three  nar- 
row reddish-brown  bands,  one  bordering  the  suture,  another  above  the 
periphery,  and  on  the  penultimate  whorl  visible  above  the  suture,  and  the 
third  band  below  the  periphery.  The  nearly  smooth  surface  is  weakly 
marked  with  lines  of  growth.  The  spire  is  conic  and  rather  high,  trun- 
cated at  the  summit  in  all  adult  shells  seen,  by  the  erosion  of  the  early 
whorls,  about  3^  remaining.  These  are  strongly  convex,  the  last  one 
globose,  without  keels  or  angles  of  any  kind,  and  with  no  expansion  or 
varix  behind  the  outer  lip.  There  is  a  distinct  and  concave  but  quite 
small  columellar  area.  The  aperture  is  moderately  oblique,  round-ovate, 
white  or  brownish  inside.  Its  posterior  angle  is  more  or  less  filled  with 
a  callous  deposit.  The  peristome  is  edged  with  a  black  line.  The  thin 
outer  lip  has  a  deep  rounded  sinus  near  its  posterior  insertion,  and  there 
is  a  second  sinus,  wider  and  not  so  deep,  at  the  base,  the  lip  projecting 
as  a  broad  truncated  lobe  between  the  two  embayments.  The  columella 
is  concave,  narrowly  calloused  and  the  parietal  callus  is  rather  thick.

Development. — The  shell  is  of  the  ordinary  simple  Naticoid  shape 
throughout  the  neanic  stage,  differing  from  P.  lapiditm  only  in  having  a 
longer  spire.  The  peculiar  Pleurotomoid  sinuosities  of  the  peristome 
have  their  origin  and  development  wholly  in  the  ephebic  stage.  In  this 
respect,  P.  bisinuatus  is  like  Pachycheilus  dalli  Pils.,  and  differs  widely 
from  Gyrotoma  and  Pleurotoma,  in  which  the  anal  notch  appears  very  early. 

This  species  is  related  to  P.  sykesi,  from  which,  however,  it  differs  totally 
in  characters  of  the  ephebic  stage.

The  shell  is  more  slender  than  P.  bisinuatus,  acutely  ovate-conic,  green, 
without  color  bands.  The  outer  and  basal  margins  of  the  peristome  have 
only  shallow  sinuses  in  place  of  the  deep  ones  of  P.  bisinuatus  ;  the  upper 
one  is  often  hardly  perceptible,  and,  when  developed,  is  nearer  the  upper 
insertion  of  the  lip  than  in  bisinuatus.  The  inner  margin  of  the  peristome 
is  less  heavily  calloused,  and  the  columellar  area  is  excessively  narrow,

descent  of  the  suture  and  the  well  developed  axial  or  umbilical  area  are 
features  unlike  P.  gracilis.  No  young  individuals  have  been  identified, 
but  they  probably  could  not  be  distinguished  from  P.  gracilis.  P.  simplex 
approaches  Littoridina  in  contour,  but  the  anteriorly  descending  suture

Development. — The  young  of  about  three  whorls  and  2  mm.  diameter 
are  essentially  similar  to  the  adult  stage  in  shape.  The  columella  is 
somewhat  wider  in  proportion. 

This  is  the  smallest  Potamolithus  now  known.  It  has  the  globular  shape 
of  P.  lapidum,  but  the  wide  columella  of  the  neanic  stage  shows  that  P. 
agapetus  is  related  to  P.  buschii.  It  differs  from  P.  buschii  by  the  evenly 
rounded  shape  of  the  last  whorl,  the  diminutive  size  and  clear  green  color, 
as  well  as  by  the  total  absence  of  a  peripheral  angle  or  keel ;  but  the 
young  stages  of  P.  buschii  are  not  always  readily  distinguishable  from  im- 
mature P.  agapetus. 

In  some  shells  the  aperture  is  smaller  than  in  that  figured,  by  reason 
of  a  greater  descent  of  the  last  whorl  immediately  behind  the  lip.  The 
columellar  crescent  varies  from  quite  narrow,  almost  linear,  to  quite  wide 
and  concave.

very  oblique,  ovate,  the  outer  lip  without  a  varix,  but  built  downward 
somewhat  near  and  at  the  upper  angle,  contracting  the  aperture.  The

Development. — At  the  end  of  the  second  whorl  the  periphery  begins  to 
be  weakly  angular,  the  shell  being  about  2  mm.  in  diameter.  Before  that 
stage  the  shape  is  globose-depressed,  with  a  rounded  periphery.  At  the 
end  of  the  third  whorl  the  angle  is  strong.  The  columella  is  very  broad,

P.  biiscJiii  is  related  to  P.  agapetus,  but  it  attains  a  larger  size,  and  dif- 
fers in  the  coloration  and  angular  periphery ;  yet  there  are  some  imma- 
ture specimens  in  the  lot  from  San  Gabriel's  Island,  which  approach  very 
near  to  P.  agapetus.  It  differs  from  P.  tapidum  and  P.  tricostatus  by  its 
wide  columella  at  all  stages  of  growth.  It  is  a  very  abundant  snail  at 
San  Gabriel's  Island,  on  the  northern  shore  of  the  Rio  de  La  Plata. 

The  figures  on  Plate  XL  represent  the  least  angular  forms  of  the 
species  from  San  Gabriel's  Island.  The  type  was  a  carinate  shell,  such 
as  that  represented  in  Plate  XLI<5,  fig.  3,  from  Fray  Bentos,  on  the  Uru- 
guay River.  The  ridge  below  the  suture  on  the  back  is  usually  incon- 
spicuous. Most  of  the  specimens  from  San  Gabriel's  Island  are  similar 
to  those  figured  on  Plate  XL,  or  somewhat  more  angular,  but  less  so  than 
shells  from  the  mainland.  They  also  have  the  ridges  or  sulcus  on  the 
back  more  strongly  developed  in  some  examples.

The  shell  is  high-trochiform,  rather  straightly  conic,  solid,  green  or 
brownish-olive,  variegated  with  pale  green  or  yellow  zigzag  streaks.  The 
smoothish  surface  is  rather  glossy,  with  the  usual  fine  growth-lines.  The 
conic  spire  is  longer  than  in  related  species,  and  often  eroded  at  the  apex. 
Whorls  nearly  4^ ,  convex.  The  last  whorl  slopes  steeply  and  with  little 
convexity  to  the  carinate  periphery,  which  is  basal  in  position.  On  the 
back  there  is  sometimes  a  very  weak  ridge  below  the  suture  and  parallel 
to  it,  but  this  is  usually  wanting.  The  base  is  flat,  and  there  is  a  rather 
wide  crescentic,  concave  columellar  area  defined  by  a  sharp  angle.  There 
is  no  varix  at  the  lip.  The  aperture  is  very  oblique,  symmetrically  ovate, 
in  fully  adult  shells  is  contracted  somewhat,  being  filled  in  above ;  with 
a  continuous,  black-edged  peristome.  The  columella  is  concave  and 
narrow.

water. 

Development. — The  youngest  shells  at  hand  lack  about  one  whorl  of 
completion.  At  this  stage  the  shape  is  practically  that  of  adults,  except 
that  there  is  no  columellar  crescent  and  the  columella  is  wide  and  flat. 
The  weak  subsutural  ridge,  when  developed  at  all,  appears  on  the  back 
of  the  last  whorl  only.  The  most  fully  developed  shells  therefore  have 
the  characters  of  the  four-whorled  stage  in  P.  tricostatus,  while  most 
shells,  wanting  the  upper  keel,  are  like  tricostatus  at  the  three-whorled 
stage. 

P.  conicus  differs  from  P.  tricostattts  by  its  smaller,  size,  more  highly 
conic  shape,  and  the  less  developed  sculpture  of  the  last  whorl.  It  is 
more  closely  related  to  P.  buschii,  both  having  the  columella  wide  during 
the  neanic  stage  ;  but  in  the  adult  stage  P.  btischii  is  depressed  and  P. 
conicus  elevated  in  shape. 

The  color  in  life  is  probably  always  more  or  less  green.  The  rich  brown 
tint  of  those  figured  may  be  due  to  change  in  alcohol,  though  I  am  not 
sure  that  this  is  the  case,  as  the  shells  were  dry  when  they  came  into  my 
possession.  A  lot  of  P.  buschii  which  had  been  in  alcohol  have  changed 
to  brown,  while  all  of  those  dried  fresh  are  green.

(Plate  XL,  Figs.  1-5.) 

Potamolithus  orbignyi  Pilsbry,  Nautilus,  X,  p.  88,  Dec.,  1896. 

The  shell  is  imperforate,  globose,  solid  and  strong.  Uniform  olive 
colored,  or  with  brown  bands  below  the  suture  and  in  the  middle  of  the 
last  whorl,  on  an  olive  or  green  ground.  Surface  smoothish,  with  faint 
growth-lines  and  fine,  very  indistinct  spiral  striae.  The  spire  is  very  short 
and  conic.  Whorls  nearly  4^  ,  strongly  convex,  the  later  third  of  the  last 
whorl  descending  more  rapidly.  The  last  whorl  is  squarish,  obtusely 
biangular,  being  shouldered  above,  flattened  in  the  middle,  and  more  or 
less  angular  at  the  basal  periphery.  The  ample  crescentic  columellar  area 
is  concave  and  bounded  by  an  angle.  The  lip  is  strengthened  by  a  narrow 
varix,  which  is  blackish  and  bevelled  to  the  lip-edge.  The  aperture  is 
very  oblique,  and  rounded-ovate.  The  outer  lip  is  thickened  within,  the 
inner  lip  heavily  calloused.  The  columella  is  broad  and  flattened.

In  the  typical  form  of  the  species  the  flattening  of  the  last  whorl  is 
nearly  vertical  below  the  shoulder.  In  other  examples  (PL  XL,  figs.  2,  3) 
the  flattened  surface  slopes  steeply,  and  the  periphery  is  somewhat  more 
angular,  though  still  rounded  off.  Young  shells  (PL  XL,  figs.  4,  4^)  with 
3^  whorls,  having  a  diameter  of  2.5  mm.,  have  a  distinct  flattening  above 
the  periphery,  though  less  marked  than  in  adults.  This  was  not  seen  by 
my  artist,  who  drew  the  peripheral  region  of  fig.  4  much  too  regularly 
rounded.  Fig.  5  represents  a  slightly  larger  shell,  diam.  2.8  mm.,  the 
basal  aspect  drawn  to  show  the  very  broad,  flat,  columellar  callus.  In 
contour  it  resembles  fig.  2. 

P.  orbignyi  is  somewhat  related  to  P.  dinochihis,  but  differs  in  the 
lower  varix,  absence  of  a  spiral  ridge  below  the  suture,  the  larger  columellar 
area,  broader  columella,  etc.  It  is  similar  to  P.  philippianus  in  shape, 
but  lacks  the  columellar  furrow  of  that  species.

(Plate  XXXIX,  Figs.  3,  30.) 

PotamolitJms  jacuhyensis  Pilsbry,  Nautilus,  XII,  p.  113,  Feb.,  1899. 

The  shell  is  globose,  solid  and  strong,  smoothish,  with  the  usual  slight 
growth  lines  and  scarcely  visible  spirals ;  covered  with  a  strong,  rich  brown 
cuticle,  becoming  more  reddish  towards  the  apex,  and  dark  green  below 
the  last  turn  of  the  suture,  behind  the  lip,  and  at  the  base.  Spire  short 
and  conic.  Whorls  4^ ,  those  of  the  spire  convex,  the  last  very  obtusely 
biangular,  being  flattened  peripherally,  subangular  at  the  shoulder,  flat- 
tened and  sloping  above  it,  and  tapering  basally.  There  is  in  some 
specimens  a  well-developed  flattened  columellar  crescent,  but  in  other 
individuals  it  is  reduced  and  inconspicuous.  The  aperture  is  large  and 
somewhat  spreading,  moderately  oblique  and  irregularly  semicircular. 
The  outer  lip  is  sharp,  with  a  dark  line  at  the  edge,  not  expanded,  and 
not  in  the  slightest  degree  varicose  or  contracted.  The  inner  lip  is 
heavily  calloused.

No  immature  stages  are  represented  in  the  series  before  me.  The 
species  belongs  to  the  more  primitive  or  youthful  group,  by  its  simplicity 
of  form,  the  absence  of  varices,  and  the  want  of  contraction  at  the  mouth. 
It  is  not  closely  related  to  any  of  the  La  Plata  drainage  forms,  but  has 
some  resemblance  to  P.  lapidum,  from  which  it  differs  by  the  obtusely 
biangular  shape,  the  much  larger  aperture,  and  the  heavily  calloused 
columella,  which  allies  it  to  species  of  the  Uruguay  system,  and  those 
following. 

POTAMOLITHUS    INTRACALLOSUS    Sp.  nOV. 
(Plate  XLW,  Figs.  9,  $a.) 

The  shell  is  imperforate,  solid,  globose  with  short,  conic  spire,  olive- 
green,  blackish  in  the  axial  region.  Surface  very  lightly  marked  with 
growth  lines.  Whorls  43^ ,  convex,  the  last  strongly  convex  below  the 
suture  and  at  the  periphery,  which  is  below  the  middle,  somewhat  flattened 
above  the  periphery  ;  base  convex  ;  an  acute  keel  divides  off  a  crescentic 
umbilical  area.  The  suture  descends  slightly  near  the  aperture.  The 
aperture  is  ample,  oblique,  very  shortly  oval.  The  peristome  is  black- 
edged,  not  expanded.  The  continuous  columellar  and  parietal  margins 
are  very  heavily  calloused,  the  columella  broad  and  flattened.  In  oblique 
view  in  the  aperture,  a  broadly  rounded  prominence  is  seen  in  the  middle 
of  the  columella.

This  small  species  of  the  P.  buschii  group  is  notable  for  its  very  broad 
columella,  with  an  internal  node  or  rounded  prominence.  This  last 
feature  differentiates  it  from  P.  ribeirensis,  which  closely  resembles  intra- 
callosus  in  shape.

shells  this  is  often  scarcely  noticeable.  The  base  tapers  and  is  not  very  con- 
vex. The  suture  descends  very  slightly  in  front.  There  is  an  extremely 
narrow  umbilical  area.  The  aperture  is  oblique  and  ample,  angular  above. 
The  outer  lip  is  thin  and  acute,  and  forms  a  half-circle.  The  columella

This  form  resembles  P.  lapidum  (d'Orb.)  in  shape,  but  differs  by  its 
very  broad  columella  and  diminutive  size.  It  is  rather  closely  related  to 
P.  bnscliii,  though  differing  by  the  rounded  periphery,  which  even  in  im- 
mature shells  shows  the  hardly  noticeable  trace  of  an  angle.  P.  intracal- 
losns  is  an  allied  species. 

A  series  of  eight  shells  from  Hiririea,  Rio  Ribeira,  State  of  Sao  Paulo, 
collected  dead,  but  not  bleached,  has  been  submitted  by  Dr.  von  Ihering. 
The  cuticle  is  olive-green  or  clear  green.  The  shape  is  about  as  in  ribeir- 
ensis.  In  several  shells  there  is  a  very  narrow  umbilical  area,  defined  by 
a  raised  line.  In  the  youngest  shells,  diam.  2  mm.,  the  columella  is  very 
wide,  as  in  ribeirensis,  but  in  the  largest  shells,  length  5.2,  diam.  4.2 
mm.,  it  is  quite  noticeably  narrower.  In  one  shell  of  this  lot  (Plate 
XLI£,  fig.  4)  there  is  a  wide,  lunate,  concave  umbilical  area,  defined 
by  an  acute  black  keel,  the  columella  being  wide,  as  in  P.  ribeirensis.  It 
measures,  length  4.2,  diam.  4  mm.  Further  material  is  needed  to  show 
the  status  of  this  form,  which  for  the  present  may  be  considered  a  race  of 
P.  ribeirensis. 

POTAMOLITHUS    CATHARINE  Sp.  nOV. 

The  shell  is  perforate,  acutely  ovate,  solid  but  strong,  covered  with  an

apex  small,  but  somewhat  obtuse,  entire  in  adult  shells.  Whorls  $%  ,  evenly 
convex,  parted  by  an  impressed  suture,  which  descends  very  briefly  at  the 
aperture.  The  last  whorl  is  strongly  convex  throughout ;  near  the  aper- 
ture it  dilates  a  little.  The  aperture  is  slightly  oblique,  ovate,  fleshy- 
gray  within,  blue-white  near  the  lip.  The  outer  lip  is  thin  and  black  at 
the  edge,  and  with  the  basal  lip  forms  a  half-circle ;  in  profile  its  edge  is 
even.  The  columella  is  heavily  calloused,  the  callus  extending  across  the 
parietal  wall,  where  it  is  less  thickened.  There  is  a  distinct  umbilical

"This  species  is  closely  related  to  the  preceding  (P.  peristomatus]  by 
its  short  shape ;  it  differs  constantly  by  wanting  a  carina,  and  by  the  non- 
reflexed  peristome"  (d'Orbigny). 

"P.  lapidnm  inhabits  the  whole  course  of  the  Parana  and  La  Plata,  from 
well  above  Corrientes  to  Buenos  Aires,  or  from  27°  to  34°  S.  lat;  on 
stones,  clinging  in  great  numbers  to  the  under  side,  at  extreme  low  water. 
It  moves  quite  actively"  (d'Orbigny). 

The  typical  form  of  P.  lapidum,  figured  by  d'Orbigny,  has  an  evenly 
rounded  last  whorl,  though  his  phrase,  "  le  dernier  [tour]  est  souvent 
comme  deprime,"  indicates  that  the  Parana  shells  are  frequently  com- 
pressed around  the  upper  part  of  the  last  whorl.  Mr.  E.  R.  Sykes,  who 
kindly  examined  the  types  of  the  species  for  me,  states  that  one  specimen 
is  so  characterized.  The  aperture  is  ample,  the  lip  not  in  the  least  con- 
tracted and  not  thickened,  the  columella  only  moderately  thickened. 

The  variety  dunkeri  of  Strobel,  from  the  Rio  de  La  Plata  at  Olivos,  near 
Buenos  Aires,  seems  to  differ  from  P.  lapidum  only  by  its  small  size  ; 
length  4,  diam.  3.5  mm.,  with  4  whorls.  It  was  described  from  a  single 
individual,  and  probably  has  no  racial  significance. 

I  have  not  seen  typical  P.  lapidum  from  the  Uruguay  River. 

In  the  State  of  Sao  Paulo  P.  lapidttm  has  been  reported  by  several 
authors  from  streams  flowing  into  the  Atlantic,  as  quoted  in  the  references 
above,  which  I  am  unable  to  control ;  but  I  doubt  whether  the  true  P. 
lapidum  is  found  in  those  waters. 

A  form  of  P.  lapidum  having  the  spire  rather  longer  than  d'Orbigny's 
type  figures  is  drawn  in  figs.  4,  5,  5«  of  Plate  XXXIX.  It  is  from  the 
Uruguay  River,  exact  locality  not  noted. 

At  Paysandu,  Uruguay  a  race  occurs  differing  somewhat  from  typical 


588  PATAGONIAN    EXPEDITIONS:     ZOOLOGY. 

P.  lapidum  (Plate  XLI£,  fig.  5).  The  shell  is  solid,  globose,  with  conic 
spire  longer  than  in  P.  lapidum,  though  the  apex  is  eroded  in  all  speci- 
mens seen.  Aperture  smaller  than  in  lapidum,  somewhat  contracted  by 
an  internal  thickening  and  contraction  of  the  lip  above.  Columella 
narrow.  A  very  narrow  umbilical  area  is  defined  by  an  angle,  which  runs 
very  close  to  the  columellar  lip.  This  race  may  be  called  var.  elatior. 

Length  4.5,  diam.  3.5  mm. 

The  long  spire  separates  this  form  at  once  from  P.paysanduanus,  which 
moreover  differs  in  the  shape  of  the  last  whorl.  In  old  examples  the 
aperture  is  more  contracted  than  in  that  figured,  and  the  spire  is  more  worn.

Potamolithus  lapiditm  stipersulcatiis,  Pilsbry,  Nautilus,  X,  p.  88,  Dec.,  1896. 
The  shell  is  like  P.  lapidum  in  its  globular  shape.  It  is  dark  green, 
usually  with  pale,  irregular  zigzag  markings,  sometimes  confined  to  the 
spire,  and  there  is  usually  an  indistinct  brownish  band  above  the  pe- 
riphery. On  the  last  whorl  an  obtuse  ridge  revolves  not  far  below  the 
suture,  most  prominent  on  the  back  ;  this  is  followed  by  a  concavity, 
below  which  there  may  be  a  second  obtuse  angle.  The  base  is  quite  full 
and  rounded.  The  suture  descends  suddenly  to  the  aperture,  which  is 
therefore  a  little  contracted,  oblique  and  ovate.  The  peristome  is  acute, 
dark-edged,  continuous,  without  trace  of  a  varix.  The  columella  is 
narrow  and  concave,  and  the  parietal  wall  is  only  moderately  thickened.

Development.  —  The  spiral  ridges  appear  only  on  the  last  whorl,  and 
usually  only  on  its  last  half.  Up  to  that  time  the  whorls  are  rounded  and 
the  shape  Naticoid.  At  all  stages  of  growth  the  columella  is  quite  narrow. 

Potamolithus  I.  supersulcatus  is  quite  closely  related  to  P.  tricostatus 
(Brot),  from  which  it  differs  chiefly  by  the  weaker  spiral  ridges,  which  are 
only  one  or  two  in  number,  not  three,  as  in  P.  tricostatus.  These  ridges 
are  not  only  less  emphatic  in  supersukatus^  but  they  do  not  appear  so

early  in  the  development  of  the  individual.  The  narrow  columella  is 
similar  in  the  two  species. 

The  specimens  from  Fray  Bentos  and  Paysandu  (where  only  a  few  were 
taken),  have  no  second  angle  below  the  upper  spiral  ridge  on  the  back. 
It  is  a  very  abundant  snail  at  San  Gabriel's  Island.  Specimens  preserved 
in  alcohol  become  brown  when  dried  ;  and  this  is  also  true  of  most,  prob- 
ably all,  of  the  dark  green  species. 

The  figures  by  von  Iterson,  on  Plate  XXXIX,  represent  a  very  dark 
green  specimen.  They  are  not  so  characteristic  as  that  on  Plate  XLI«, 
which  shows  the  back  of  an  example  with  the  color-pattern  fully  developed.

From  the  sharpness  of  the  outer  lip,  I  am  disposed  to  think  that  none 
of  the  specimens  is  fully  mature,  though  the  largest  one  must  be  nearly 
so,  as  it  is  eroded  like  an  old  shell.  It  differs  from  P.  lapidum  by  the 
longer  spire,  small  size  and  pale  color.  There  are  two  specimens  in  the 
collection  of  the  Academy  of  Natural  Sciences  of  Philadelphia,  three  in 
that  of  the  Museu  Paulista.

The  shell  is  subglobular  with  a  short  conic  spire,  solid  and  strong, 
olive-colored,  more  or  less  streaked  or  mottled  with  black.  The  surface 
is  dull,  lightly  marked  with  fine  lines  of  growth  and  extremely  weak, 
coarse  spirals  ;  3}^  whorls  of  the  spire  remain,  the  apex  being  eroded  in 
adult  shells.  The  whorls  are  strongly  convex,  parted  by  a  deep  suture, 
which  descends  briefly  at  the  aperture.  The  last  whorl  is  convex  through-

This  is  a  larger  species  than  P.  lap^d^l1n  (d'Orb.),  with  the  last  whorl 
decidedly  more  dilated,  the  aperture  more  oblique,  and  a  crescentic  umbili- 
cal area  developed.  When  collected,  the  shells  were  heavily  coated  with 
black  ferrous  material  and  most  of  them  bear  egg-capsules  on  the  shell.

Potamolithus  paysanduanus  v.  Ihering,  Nautilus,  XXIV,  1910,  p.  15,  with 

forms  sinulabris  and  im^ressus. 

The  shell  is  imperforate,  solid,  subglobular,  olive-colored,  smooth  except 
for  weak  growth-lines,  shining.  The  spire  is  very  low,  conic,  the  apical 
whorls  eroded  in  all  the  individuals  seen ;  three  whorls  remaining  are 
strongly  convex.  The.  last  whorl  is  swollen  below  the  suture,  then  some- 
what flattened,  rounded  at  the  periphery  and  base.  The  suture  descends 
abruptly  to  the  aperture  in  fully  adult  shells.  The  aperture  is  somewhat 
oblique,  ovate.  The  peristome  is  black,  with  obtuse,  flat  edge ;  the  outer 
and  basal  margins  are  narrow  ;  the  upper  part  of  the  outer  lip  and  the 
upper  angle  are  wide,  and  the  columellar  and  parietal  margins  are  very 
wide  and  flat,  black,  contracting  the  aperture.

Paysandu,  Uruguay.  Dr.  Florentine  Filippone.  Types,  No.  103,070, 
A.  N.  S.  P. 

This  form  differs  from  P.  lapidum  by  its  contracted  aperture,  the  inner 
and  upper  margins  of  the  peristome  being  heavily  thickened  within,  the 
thickening  covered  with  a  blackish  cuticle.  In  P.  lapidum  the  aperture 
is  ample,  with  no  such  heavy  thickening.  In  the  stage  immediately  pre- 
ceding maturity  the  columella  has  a  moderate  white  callus  within,  and 
the  parietal  callus  is  quite  thin.  The  type  specimen  is  figured.  Six 
others  I  have  seen  show  no  significant  variation. 

With  these  specimens  two  other  forms  were  sent  which  seem  to  be 
phases  or  varieties  of  the  same  species,  but  not  intergrading  in  the  mate- 
rial examined.  Whether  they  occurred  in  the  same  or  in  separate  colonies 
is  not  known. 

Form  SINULABRIS  (Plate  XLIa,  figs.  2,  3).  The  shell  differs  from  typical 
P.  paysanduanus  by  having  a  low  rounded  ridge  behind  the  outer  lip, 
which  is  black,  contracted,  and  has  a  rounded  sinus  above.  The  basal  lip 
is  narrow  and  a  little  retracted.  The  columellar  and  parietal  margins  are 
not  so  broad  as  in  paysanduanus.  There  is  an  excavated  umbilical  area, 
but  it  is  generally  not  distinctly  defined  by  an  angle.  The  shape  is  other- 
wise as  in  P.  paysanduanus.

Form  IMPRESSUS  (PI.  XLI#,  figs.  4,  40).  The  shell  resembles  typical 
paysanduanus  as  far  as  the  middle  of  the  last  whorl,  after  which  it  has  an 
impressed,  concave  zone  a  short  distance  below  the  suture,  and  usually  a 
sinus  in  the  upper  part  of  the  lip.  The  outer  lip  is  thin  and  sharp,  with 
no  external  varix  or  swelling.  The  shell,  under  the  cuticle,  is  light  yellow. 

Length  5,  diam.  4.8  mm. 

Up  to  the  time  of  reaching  the  size  of  adult  P.  paysanduanus,  this  form 
grows  normally.  After  that,  instead  of  forming  a  contracted  aperture,  it 
adds  a  half  whorl,  which  is  distorted  by  a  superior  concave  zone  and  finally 
terminates  with  a  thin  outer  lip.  The  specimens  were  sent  with  typical 
paysanduanus.

POTAMOLITHUS  QUADRATIC  Pilsbry  &  von  Ihering,  sp.  nov. 

(Plate  XLIa,  Figs.  6,  6a.) 

The  shell  is  solid,  imperforate,  light  olivaceous-brown,  lightly  marked 
with  growth-lines,  shining.  The  spire  is  very  short,  y/2  whorls  remain- 
ing, the  apex  being  eroded.  The  penultimate  whorl  has  a  strong  angle 
at  its  upper  third,  is  flat  and  horizontal  above  the  angle,  flat  and  sloping 
below  it.  The  last  whorl  is  bicarinate,  the  peripheral  and  shoulder  carinae 
being  about  equally  strong,  giving  it  a  square  appearance.  The  base 
tapers  to  a  rather  high  ridge,  which  bounds  a  wide,  excavated,  umbilical 
area.  The  peripheral  angle  becomes  obsolete  just  behind  the  outer  lip, 
and  it  is  visible  only  on  the  last  whorl.  The  aperture  is  very  oblique, 
ovate,  white  within.  Peristome  a  little  contracted,  its  face  flat  and  thick- 
ened within,  at  and  above  the  periphery  and  in  the  upper  angle  ;  below 
the  periphery  it  is  thin  and  a  little  retracted.  The  columella  and  parietal 
wall  are  moderately  calloused,  a  groove  in  the  face  running  parallel  to 
their  outer  margin. 

Length  3.9,  diam.  4  mm. 

Paysandu,  Uruguay.     Dr.  Fl.  Filippone. 

This  snail  differs  from  P.  carinifer  in  the  shape  of  the  last  whorl,  the 
much  stronger  upper  keel  (which  is  developed  earlier)  and  in  having  a 
large  umbilical  area.  It  lacks  the  median  keel  and  variegated  colora- 
tion of  P.  tricostatus. 

A  young  shell  2.4  mm.  diam.  consists  of  2>£  whorls,  the  first  il/2  are 
rounded ;  the  keel  at  the  shoulder  then  begins,  rapidly  becoming 
strong.  The  columella  is  very  wide,  its  face  excavated. 

POTAMOLITHUS  CARINIFER  sp.  nov. 

(Plate  XLIa,  Figs.  5,  50.) 

The  shell  is  imperforate,  trochiform,  solid,  blackish-brown  in  old 
individuals,  the  shell  of  a  brick-red  tint  below  the  cuticle.  Surface  lightly 
marked  with  growth-lines.  The  spire  is  very  short,  conoidal.  Whorls 
about  4,  the  earlier  ones  convex.  The  first  half  of  the  penultimate  whorl 
is  convex  ;  then  a  small  carina  gradually  arises  a  short  distance  below 
the  suture,  the  surface  flat  and  sloping  below  it ;  a  little  later  a  strongly 
projecting  keel  appears  just  above  the  lower  suture,  being  uncovered  by 
the  descent  of  the  last  whorl.  The  last  whorl  has  a  strongly  projecting 


PILSBRY:   NON-MARINE  MOLLUSCA  OF  PATAGONIA.  593 

peripheral  keel  and  a  small  keel  near  the  suture,  the  surface  flat  between 
the  keels.  The  base  is  a  little  convex.  The  umbilical  area  is  slightly 
excavated,  but  not  bounded  by  a  ridge  or  keel.  The  suture  descends 
slowly  in  its  last  third  of  a  whorl,  and  then  rapidly  at  the  aperture.  The 
aperture  is  very  oblique,  shortly  ovate,  flesh-tinted  inside.  Peristome 
blunt,  not  expanded.  Columella  concave,  rather  narrow,  its  face  slightly 
grooved.  Parietal  wall  rather  heavy-calloused.

This  species  closely  resembles  P.  microthauma,  from  which  it  differs 
by  the  entire  absence  of  a  varix  behind  the  outer  lip  ;  the  coloration  is 
also  different,  but  the  type  is  probably  abnormally  dark,  being  an  old  shell 
which  has  lost  part  of  the  cuticle.

The  shell  is  trochiform,  solid  and  strong ;  olive-colored,  profusely 
marked  with  irregular  or  zigzag  buff  spots.  The  surface  is  glossy  when 
clean,  with  the  usual  weak  growth-lines  and  minute  spiral  striae.  Spire 
short,  convexly  conoidal.  Whorls  4^  ,  the  first  three  convex.  A  ridge 
then  gradually  appears  below  the  suture,  increasing  to  a  strong  carina  on 
the  back  of  the  last  whorl.  The  last  whorl  has  also  a  thick,  strong  keel 
defining  the  base,  and  a  short  keel,  chiefly  dorsal,  above  the  middle  of  the 
slightly  convex  surface  between  the  two  keels.  The  base  is  flattened,  but 
a  little  convex ;  a  small  columellar  area  is  usually  distinctly  differentiated. 
The  last  whorl  expands  slightly  at  its  termination,  and  then  contracts. 
The  aperture  is  very  oblique,  rounded-ovate,  bluish-white  within.  The 
peristome  is  continuous,  black-edged.  The  columella  is  narrow  and  con- 
cave ;  and,  with  the  parietal  wall,  is  moderately  calloused.

upper  and  lower  keels  are  already  strongly  developed  near  the  lip,  but 
there  is  no  trace  of  the  intermediate  keel,  which  in  adults  is  less  than  one 
whorl  long.  The  two  keels  present  are  very  weak  at  the  beginning  of 
the  fourth  whorl,  the  basal  one  stronger  there  than  the  upper,  so  that 
apparently  at  2>£  whorls  the  form  must  be  Naticoid,  like  P.  lapidum. 
The  next  stage,  at  about  3  whorls,  would  have  a  basal  angle  only,  like 
P.  buschii.  The  columella  is  narrow,  as  in  P.  lapidum,  throughout  the 
neanic  stage.  The  ephebic  stage  is  marked  by  a  slight  expansion,  forming 
a  narrow  and  low  varix.  Fully  adult  shells  are  markedly  gerontic  by 
reason  of  the  strong  post-variceal  contraction. 

The  figures  of  this  species  given  by  Brot  are  unsatisfactory  from  being 
too  small  properly  to  show  its  characters.  The  median  keel  is  shown  too 
low  in  position.  The  original  locality  was  indefinite,  but  comprised  an 
area  including  the  river  in  the  neighborhood  of  Paysandu.  Three  speci- 
mens of  the  original  lot,  received  from  Dr.  Brot,  agree  with  those  col- 
lected by  Dr.  Rush  at  Paysandu. 

POTAMOLITHUS    HATCHERI  Sp.   nOV. 
(Plate  XXXVIII,  Figs.  6,  6a.) 

The  shell  is  imperforate,  turbinate,  solid  and  strong,  pale  yellowish- 
green,  becoming  darker  and  narrowly  streaked  with  dark  green  on  the  later 
half  of  the  last  whorl  ;  on  the  penultimate  whorl  the  color  changes  to  rich 
reddish-brown,  becoming  darker  towards  the  summit.  Surface  glossy,  with 
faint  growth-lines  and  fine,  indistinct  spiral  striae.  >Spire  conic,  high  and 
rather  slender,  the  apex  lost  in  the  type,  a  pit  in  its  place.  Three  whorls 
remain,  the  first  two  of  them  evenly  convex.  The  last  fourth  of  the 
penultimate  whorl  is  very  obscurely  biangular,  the  lower  angle  more  dis- 
tinct than  the  other.  These  angles  are  more  pronounced  on  the  face  of 
the  last  whorl,  and  on  its  later  half  the  upper  angle  rises  into  a  strong  keel, 
the  surface  above  it  concave ;  at  the  same  time,  the  lower  angle  loses  in 
prominence,  and  is  quite  lost  behind  the  lip.  An  extremely  weak  spiral 
ridge  is  developed  on  the  back  below  the  suture.  The  base  is  rounded. 
The  last  third  of  a  volution  of  the  suture  descends  more  rapidly.  There 
is  no  trace  of  a  varix  at  the  lip.  The  aperture  is  quite  oblique,  as  wide  as 
high,  almost  circular,  but  slightly  angular  above.  The  lip  is  obtuse,  thick- 
ened within,  with  a  continuous  blackish  marginal  line.  The  columella  is 


PILSBRY:    NON-MARINE  MOLLUSCA  OF  PATAGONIA.  595 

very  concave,  and  not  wider  than  the  outer  lip,  and  is  bounded  outside  by 
a  linear,  hardly  noticeable  columellar  area.

This  species  is  based  upon  a  single  specimen,  quite  adult  and  to  all 
appearance  perfectly  normal,  yet  so  unlike  other  known  species  that  its  rela- 
tionships are  doubtful.  The  prominent  characters  of  P.  hatcheri  are  the 
elevated  and  tapering  spire  and  the  approximation  of  the  two  angles  of  the 
last  whorl,  the  upper  one  finally  dominating,  while  the  lower  becomes  obso- 
lete on  the  last  half  of  the  last  whorl.  The  absence  of  a  lip-varix  and  of 
a  noticeable  columellar  area,  as  well  as  the  rather  narrow  columella,  are 
features  like  the  P.  lapiditm  group.  The  young  shell,  up  to  the  middle  of 
the  penultimate  whorl,  must  be  ovate,  without  angles ;  but  in  the  absence  of 
immature  specimens,  not  much  can  be  said  of  the  development  of  the  species. 

It  is  named  to  honor  Mr.  J.  B.  Hatcher.

Potamolithiis  dinocJiiliis  Pilsbry,  Nautilus,  X,  p.  87,  Dec.,  1896. 

The  shell  is  globosely  trochoidal,  imperforate,  very  solid  and  thick  ; 
green,  profusely  marked  with  irregular,  zigzag  buff  streaks.  The  surface 
is  smoothish,  with  the  usual  faint  growth-lines  and  indistinct  fine  spiral 
striae.  The  spire  is  conic,  rather  high  when  preserved  entire  (fig.  8),  but 
worn  to  a  blunt  summit  in  all  adult  shells  seen.  There  are  4^  whorls, 
but  only  2^  to  3  remain  in  adults.  The  earlier  whorls  are  rounded,  but 
at  the  beginning  of  the  last  a  small  ridge  arises  a  short  distance  below  the 
suture.  The  last  whorl  is  somewhat  flattened  and  slopes  steeply  to  the 
basal  periphery,  which  is  full  and  narrowly  rounded  or  subangular.  The 
ridge  below  the  suture  is  narrow,  but  well  developed  on  the  back.  The 
columellar  area  is  ill-defined  and  very  narrow.  The  lip  is  strengthened 
by  a  varix,  which  above  the  periphery  is  very  high,  massive  and  recurved, 
but  becomes  weak  at  the  base.  The  aperture  is  very  oblique,  contracted, 
irregularly  rounded,  with  the  margins  built  out  beyond  the  varix,  con- 
tinuous around  the  mouth,  thick  and  obtuse.  The  columella  is  strongly 
concave,  and  moderately  calloused,  not  more  than  the  lip  generally.

Development. — The  series  at  hand  contains  no  young  shells,  one  only 
(PI.  38,  fig.  8)  has  not  yet  formed  the  post-variceal  contraction.  It  ap- 
pears however  that,  until  the  last  whorl  is  reached,  the'shell  has  the  primi- 
tive Naticoid  shape.  The  last  whorl  represents  morphologically  the 
second  neanic  substage  of  such  accelerated  forms  as  P.  microthaiima.  The 
strong  post-variceal  contraction  and  heavy  thickening  of  the  inner  margin 
of  the  peristome  declare  that  the  last  stage  is  distinctly  gerontic. 

P.  dinochilus  differs  conspicuously  from  P.  microthauma,  hidalgoi  and 
peristomattis  by  the  absence  of  a  peripheral  keel,  and  from  P.  orbignyi 
by  the  shape  of  the  last  whorl  and  the  ill-developed  columellar  area.  It 
has  perhaps  more  in  common  with  the  P.  lapidum  group,  especially  in  the 
coloration  and  the  persistence  of  the  Naticoid  form  to  the  beginning  of  the 
last  whorl ;  but  the  very  high,  massive  lip-varix  of  P.  dinochilus  is  a  fea- 
ture unlike  any  of  the  lapidum  group.

The  shell  is  imperforate,  trochoidal,  with  flattened  base  and  conic  spire ; 
moderately  solid.  The  type  specimen  is  dull  reddish-brown,  somewhat 
olive-tinted  at  the  base,  and  olivaceous  blackish  on  the  lip-varix ; .  but 
some  immature  shells  of  the  original  lot  are  dull  olive-colored,  darker  on 
the  keel.  The  surface  is  slightly  marked  with  growth-lines.  The  spire  is 
conic.  There  are  4^  whorls,  the  first  2^  convex;  then  a  keel  appears, 
immediately  above  and  filling  the  suture.  The  last  two-thirds  of  the  last 
whorl  descends  slowly,  the  peripheral  keel  projecting  above  the  suture. 
The  last  whorl  is  flat  and  slopes  steeply  above  the  peripheral  keel,  and  is 
slightly  convex  below  it.  A  very  narrowly  crescentic  columellar  area  is 
defined  by  an  inconspicuous,  but  acute  angle.  The  outer  lip  is  strength- 
ened by  a  moderately  strong  varix,  not  continued  below  the  termination 
of  the  peripheral  keel.  The  aperture  is  extremely  oblique,  rounded-ovate, 
angular  above  and  indistinctly  so  outwardly,  at  the  termination  of  the

A  very  weak  ridge  below  and  near  the  suture  may  be  seen  in  two 
immature  shells  of  the  type-lot,  but  this  is  not  developed  in  the  others. 
The  early  neanic  substage  is  Naticoid,  like  the  corresponding  age  in  P. 
microthaiima.  The  rest  of  the  neanic  stage  is  the  equivalent  of  substage 
2  in  P.  microthaiima.  The  deep  descent  of  the  last  whorl  gives  a  markedly 
gerontic  character  to  the  adult  stage.  P.  hidalgoi  is  therefore  less  evolved 
sculpturally  in  wanting  the  third  neanic  substage,  senile  characteristics 
supervening  earlier. 

The  species  is  named  in  honor  of  Dr.  J.  G.  Hidalgo  of  Madrid,  author 
of  a  beautiful  work  on  the  mollusks  of  the  Spanish  Commission  to  South 
America,  among  many  other  important  labors.

Potamolithus  microthauma  Pilsbry,  Nautilus,  X,  p.  87,  Dec.,  1896. 

The  shell  is  imperforate,  biconic,  very  solid  and  strong.  The  last  whorl 
is  olive-green,  rather  profusely  marked  with  irregular  buff  maculae,  which 


598  PATAGONIAN    EXPEDITIONS  I     ZOOLOGY. 

are  sometimes  absent  on  the  base.  The  lip-varix  is  bright  green.  On  the 
penultimate  whorl  the  ground-color  changes  to  purple-brown  and  the 
markings  disappear,  the  earlier  whorls  being  uniform  dark  purple-brown. 
The  surface  shows  delicate  growth-striae  and  a  very  minute,  almost  effaced 
spiral  striation.  The  spire  is  conic,  with  straight  outlines,  the  apex  entire 
and  obtuse,  though  small.  Whorls  5,  the  early  ones  convex,  the  first  2% 
being  rounded,  without  trace  of  keels.  A  peripheral  keel  then  begins, 
strong  from  the  beginning,  and  projecting  flange-like  above  the  suture. 
The  last  whorl  descends  slowly  from  about  its  last  third  and  much  more 
rapidly  near  the  aperture.  The  peripheral  keel  projects  very  strongly  and 
is  slightly  undulating  ;  and  a  small  keel  arises  below  the  suture,  becomes 
stronger  on  the  back,  then  gradually  decreases.  On  the  base,  midway 
between  the  periphery  and  center,  a  low  keel  revolves,  the  area  within  it 
being  nearly  flat.  There  is  a  very  narrow  crescentic  columellar  area. 
The  outer  lip  is  strengthened  by  a  very  high  and  massive  varix,  which  is 
recurved  above,  with  a  rib  on  its  face  running  to  the  lip-edge,  and  below 
passes  into  the  basal  keel.  The  aperture  is  very  oblique,  ovate  ;  the  outer 
lip  thin  at  the  edge.  The  columella  is  narrowly  calloused  and  regularly 
concave.

Development.  —  The  neanic  stage  is  sharply  divided  into 

(1)  A  lapidum  substage,  in  which  the  shell  is  rounded,  without  keels, 
comprising  the  first  2^  whorls. 

(2)  A  carinate  substage,  initiated  by  the  almost  abrupt  rise  of  the  periph- 
eral carina.    From  a  half  whorl  to  a  whorl  this  is  the  only  keel  developed. 
This  stage  corresponds  to  the  adult  P.  hidalgoi,  and  is  of  brief  duration. 

(3)  The  basal  and  the  subsutural  carinae  begin,  weak  at  first,  becoming 
stronger  near  the  end  of  the  substage. 

The  ephebic  stage  is  announced  by  the  expansion  to  form  the  varix, 
which,  however,  is  not  terminal,  the  whorl  continuing  and  contracting 
beyond  it,  thus  assuming  gerontic  characteristics. 

P.  microthauma  is  related  to  P.  hidalgoi  and  P.  peristomatus,  but  it  is 
a  much  more  evolved  form  than  either,  structures  added  in  the  second

and  third  neanic  substages  of  microthattma  being  superposed  upon  the

Potamolithiis  rushii  Pilsbiy,  Nautilus,  X,  p.  89,  Dec.,  1896. 

The  shell  is  imperforate,  wider  than  high,  biconvex,  very  solid  and 
strong  ;  light  green,  the  last  half  of  the  last  whorl  dusky  green,  the  keels 
rather  bright  green  ;  the  early  whorls  being  dark  reddish-brown.  The 
surface  is  somewhat  glossy,  with  faint,  fine  growth-lines  and  barely  per- 
ceptible spiral  lines.  The  spire  is  convex,  the  apex  obtuse.  Whorls  4, 
but  the  first  is  eroded,  leaving  a  pit,  in  all  the  adult  shells  seen.  The 
whorls  are  convex,  with  seam-like  sutures.  In  the  latter  part  of  the  pe- 
nultimate whorl  the  peripheral  keel  is  usually  visible  at  the  suture.  The 
last  whorl  has  a  very  strong  peripheral  keel,  the  surface  being  concave 
above  and  below  it.  Above  the  concavity  the  upper  surface  is  convex, 
the  convexity  rising  into  a  hump  on  the  back,  then  disappearing,  the  last 
fourth  of  the  whorl  being  flat.  The  base  has  a  thick  and  prominent  keel, 
defining  a  concave  yellowish  columellar  area.  The  outer  lip  has  a  high, 
narrow  varix  at  the  edge.  The  aperture  is  very  oblique,  short-ovate, 
nearly  circular,  with  a  continuous,  black-edged  margin.  The  oblique 
columella  is  very  broad,  with  a  gutter  or  concavity  near  to  and  parallel 
with  the  inner  margin.

Development. — The  youngest  specimens  seen  have  three  whorls  and  a 
diameter  of  3  mm.  They  have  the  depressed  contour  of  adults  and  are 
strongly  carinate  peripherally,  but  the  carina  is  distinctly  weaker  in  front 
of  the  mouth,  apparently  indicating  that  it  begins  when  the  shell  has 
nearly  two  whorls  and  a  diameter  of  about  a  millimeter.  At  the  3  mm. 
stage  the  columella  is  very  broad,  semicircular,  with  a  deep  excavation  and 
rodrlike  inner  border  (PI.  XXXVIII,  fig.  4).  Very  late  in  the  neanic  stage 
the  basal  keel  appears,  the  shell  then  being  about  5  mm.  in  diameter  ;  the 
columellar  area  being  very  narrow,  at  first  linear.  The  rib  or  convexity 


600  PATAGONIAN    EXPEDITIONS  I     ZOOLOGY. 

of  the  upper  surface  is  also  of  late  appearance,  these  structures  belonging 
to  the  third  neanic  substage,  the  second,  or  unicarinate,  substage  thus 
occupying  the  greater  part  of  the  neanic  stage.  The  discontinuation  of 
the  upper  ridge  or  hump  initiates  the  ephebic  substage.  The  marginal 
varix  and  the  absence  of  any  tendency  of  the  last  whorl  to  descend  or 
loosen  its  coil  anteriorly,  show  that  this  species  is  at  its  acme.  It  has 
none  of  the  stigmata  of  senility  which  are  so  manifest  in  P.  micro- 
thauma,  P.  hidalgoi,  etc. 

There  is  some  variation  in  the  degree  of  depression  of  the  whole  shell, 
the  amplitude  of  the  columellar  area  and  in  the  prominence  of  the  hump 
on  the  back,  which  is  sometimes  almost  suppressed.  The  size  also  varies, 
one  specimen  before  me  with  the  varix  nearly  complete  measuring  only 
5  mm.  in  diameter. 

The  relationship  between  P.  rushii  and  P.  iheringi  is  exceedingly 
interesting.  The  two  species  are  similar  in  general  color-scheme,  in  the 
varix,  absence  of  more  rapid  descent  of  the  suture  towards  the  mouth, 
etc.,  but  are  totally  diverse  in  contour,  the  one  being  carinate,  the  other 
smooth  and  Naticoid.  Yet  it  is  significant  that  while  P.  iheringi  has  no 
trace  of  a  peripheral  keel,  the  green  band  occupies  the  same  position  as 
that  coloring  the  keel  in  P.  rushii.

(Plate  XXXIX,  Figs.  2,  za.) 

Potamolithus  iheringi  Pilsbry,  Nautilus,  X,  p.  87,  Dec.,  1896. 

The  imperforate  or  rimate  shell  is  globular-conic,  very  solid  and  strong, 
pale  olive-yellow,  with  a  sharply  defined,  bright  green  band  bordering  the 
suture  below  and  another  immediately  above  the  periphery,  visible  as  a 
narrow  border  on  the  penultimate  whorl  above  the  suture ;  the  columellar 
area  being  also  dull  green.  Very  faint  growth-lines  and  an  almost  effaced 
spiral  striation  are  visible  under  the  lens.  The  spire  is  low  conoidal,  the 
suture  clearly  incised  but  not  impressed.  Whorls  4^  ,  the  first  half  whorl 
usually  lost  in  adult  shells ;  the  rest  are  slightly  convex,  the  last  whorl 
being  globular,  at  first  regularly  rounded,  but  its  last  third  descends  slowly, 
and  is  perceptibly  flattened  obliquely  in  the  peripheral  region,  being  more 
full  and  convex  below.  The  base  is  convex,  but  there  is  a  concave  cres- 
centic  columellar  area  defined  by  an  inconspicuous  angle.  The  outer  lip 
is  strengthened  by  a  moderately  strong  varix,  bevelled  to  the  lip-edge, 


PILSBRY:   NON-MARINE  MOLLUSCA  OF  PATAGONIA.  60 1 

and  weak  at  the  base.  The  aperture  is  quite  oblique,  ovate,  subangular 
above.  The  outer  lip  is  thick  within.  The  columellar  margin  is  some- 
what straightened,  the  columella  very  wide,  flattened  and  excavated,  a 
rather  deep  furrow  running  parallel  with  and  near  to  the  inner  edge.

Development. — The  youngest  individuals  seen  have  3^  whorls,  with  a 
length  of  2.3  and  diam.  of  2.8  mm.  They  are  therefore  more  depressed 
than  the  adult  stage,  and  have  both  green  bands  well  developed.  The 
subsutural  green  band  begins  at  the  end  of  the  second  or  beginning  of 
the  third  whorl.  The  axis  is  wholly  imperforate.  The  columella  is  very 
broad,  half-round,  with  the  excavation  in  its  face  deeper  than  in  adults. 
At  no  stage  are  there  any  traces  of  carinae  or  protuberances. 

I  have  seen  a  long  series  of  this  species.  The  characters  described 
above  are  very  uniform,  and  it  is  readily  known  by  the  Naticoid  shape, 
grooved  columella  and  green  bands.  Named  in  honor  of  Dr.  H.  von 
Ihering. 

POTAMOLITHUS    PHILIPPIANUS  Sp.   nOV. 
(Plate  XLI£,  Figs,  i,  \a,  2.) 

The  shell  is  globose,  solid  and  strong,  light  greenish  yellow,  with  a 
narrow  dark  green  border  below  the  suture,  the  apex  pinkish.  The  surface 
is  nearly  smooth,  showing  faint  growth-lines  and  fine,  very  indistinct 
spiral  striae.  Spire  low,  conic,  the  apex  minute,  entire.  Whorls  4^ , 
convex,  the  last  not  more  rapidly  descending,  distinctly  flattened  periph- 
erally, shouldered  above  the  flattened  zone,  very  obtusely  subangular 
below  it,  the  base  convex,  with  a  rather  wide,  concave  and  crescentic 
columellar  area,  the  lower  portion  of  which  is  bounded  by  an  angle.  The 
outer  lip  is  strengthened  by  a  moderately  high  varix  near  the  margin,  much 
lower  at  the  base,  and  continuous  with  the  angle  bounding  the  columellar 
area.  The  aperture  is  very  oblique  and  semicircular,  the  outer  margin 
being  deeply  arcuate,  the  inner  somewhat  straightened.  The  columella  is 
rather  broad,  with  a  shallow  furrow  on  its  face ;  and  the  outer  edge  is 
somewhat  elevated  near  the  insertion,  leaving,  in  the  type  specimen,  a 
shallow  crevice  behind  it,  not  visible  in  younger  shells.

Development. — The  smallest  specimens  seen  measure  3  mm.  diam., 
2.8  high.  The  peripheral  flattening  is  already  weakly  perceptible.  There 
is  no  trace  of  a  basal  angle  or  columellar  area,  but  the  columella  is  very 
wide,  almost  semicircular,  with  a  deep  excavation  in  its  face.  The  angle 
bounding  the  columellar  area  is  developed  very  late,  appearing  only  on 
the  last  whorl. 

This  species  is  described  from  four  specimens,  none  of  them  perhaps 
completely  mature.  The  shell  figured  is  almost  mature,  but  lacks  the 
post-variceal  contraction  of  the  lip,  which  would  probably  be  acquired. 
Two  of  the  shells  have  a  peripheral  brown  band,  fading  out  at  the  edges, 
and  one  has  a  second  fainter  band  on  the  outer  part  of  the  base. 

Compared  with  P.  iheringi,  this  species  differs  by  its  somewhat  biangular 
shape,  the  lower  varix  and  the  coloration.  P.  paysandtianus  differs  more 
radically  by  its  columella.

The  shell  is  thin,  nearly  equilateral,  pale  straw-yellow,  glossy,  finely 
striate.  The  beaks  are  low  and  broad,  the  embryonic  stage  marked  off  by 
a  contraction  or  gutter.  Anterior  end  almost  symmetrically  rounded;  pos-

I  believe,  entirely  misunderstood  them.  His  Pisidium  argentinum  may  pos- 
siBly  be  P.  sterkiannm  Pils.  For  the  purpose  of  affording  a  basis  for  com-

The  shell  is  fragile,  olive-gray  when  full-grown,  the  young  ones  grayish, 
with  a  yellow  zone  at  the  basal  edge.  The  ends  are  more  abrupt  than 
in  M.  patagonicum,  and  the  beaks  fuller.  The  teeth  are  decidedly  more 
delicate  and  compressed  than  in  M.  patagonicum.

From  the  Rio  Camaguan,  Rio  Grande  do  Sul,  Dr.  von  Ihering  sent  a 
single  specimen  similar  to  M.  argentinum,  except  in  being  shorter  and 
more  globose;  length  7.9,  alt.  7,  diam.  5.2  mm.  If  such  proportions 
characterize  a  race  in  that  river,  it  will  probably  be  considered  as  speci- 
fically distinct.

In  the  fresh  specimens  from  65  miles  north  of  the  Rio  Chico  the  right 
valve  has  below  the  beak  a  horizontal  arcuate  tooth,  with  a  straight 
oblique  tooth  above  it  nearer  the  anterior  (short)  end.  The  laterals  appear 
to  be  smooth.  The  left  valve  has  a  rather  long  slender  tooth,  lower  and 
angulated  in  the  middle,  the  anterior  ramus  stouter  and  longer  than  the 
posterior.  The  lateral  teeth  arise  under  the  visible  part  of  the  umbones 
(while  in  P.  patagonicum  they  arise  beyond  it).  They  are  high  and  tri- 
angular in  profile  (fig.  16).  The  shells  are  light  olive  externally,  with

Specimen  from  a  spring  25  miles  above  the  Sierra  Oveja  are  similar, 
except  that  the  lower  cardinal  tooth  of  the  right  valve  is  stouter.  One 
opened  contained  eleven  young  ones  about  1.6  mm.  long,  almost  filling 
the  cavity. 

The  teeth  are  practically  identical  in  specimens  from  six  lots  examined.

of  another  anterior  to  it.  These  teeth,  especially  the  anterior  one,  are  too 
distinctly  defined  in  fig.  10.  Lateral  teeth  very  short  and  moderately 
strong,  distant  from  the  beaks.

Arroyo  Eke,  near  the  head  waters  of  Spring  Creek,  2400  ft.  elevation. 

This  clam  differs  from  P.  magellanicum  by  the  shorter  anterior  end,  short 
lateral  teeth  remote  from  the  cardinals,  the  anterior  laterals  standing  at  an 
angle  approaching  100°  with  the  posterior  laterals,  on  account  of  the  curva- 
ture of  the  anterior  margin.  In  P.  magellanicum  the  angle  of  divergence 
of  the  teeth  is  decidedly  greater,  and  they  are  longer.  The  cardinal  teeth 
are  almost  obsolete  in  P.  patagonicum,  not  projecting  above  the  level  of 
the  hinge. 

In  the  type  lot,  as  well  as  in  all  the  specimens  from  springs  recorded 
above,  the  surface  is  straw-yellow  and  the  striation  fine  and  even,  without 
periodic  lines  indicating  growth-arrest.  In  specimens  from  small  streams 
in  the  same  region  the  shell  attains  a  greater  size,  up  to  length  6.9,  alt. 
5.8  mm.,  and  is  marked  externally  with  several  darker  concentric  streaks, 
indicating  periods  of  growth-arrest  ;  the  color  is  generally  paler.  This 
form,  which  may  be  called  var.  zonifer,  is  figured  on  Plate  XLVItf,  fig.  9. 
It  is  from  small  streams  on  the  Rio  Chico  fifteen  and  twenty-five  miles 
above  the  Sierra  Oveja.

the  middle.  The  lateral  teeth  are  rather  long  and  not  remote  from  the

It  may  be  well  here  to  correct  the  nomenclature  of  an  allied  genus  of 
the  La  Plata  and  Amazon  basins,  formerly  known  as  Castalia  Lam.,  1819. 
This  name  was  believed  to  be  preoccupied  by  Savigny,  in  l^ermes,  and 
Tetraplodon  Spix,  1827,  has  been  substituted  for  it. 

The  late  Professor  Eduard  von  Martens  wrote  to  me  under  date  of  18 
Oct.,  1893,  as  follows  :  "  Concerning  Castalia,  the  date  of  Savigny's  genus 
of  Annelids  is  given  as  1817  in  Agassiz's  '  Nomenclator,'  it  is  true,  but  I 
am  not  sure  that  this  is  correct.  I  find  Savigny's  genus  first  in  his  Sys- 
tem of  Annelids,  which  is  said  to  have  been  published  in  1820,  whereas 
Castalia  Lamarck  was  published  in  1819,  vol.  V,  part  I,  of  Lamarck's  first 
edition  [of  the  Animaux  sans  Vertebres\ 

"P.  S.  I  have  consulted  in  these  days  the  original  edition  of  L.  Agas- 
siz's Nomenclator  and  I  find  concerning  Castalia  the  note  : 

"  '  Castalia  Sav.,  Syst.  annelid.,  1817.  Savigny  Systeme  des  Annelides, 
presente  a  1'Acad.  des  Sci.  en  1817,  public  en  1826.' 

"It  is  true  that  there  is  also  an  edition  of  the  same  work,  in  folio, 
which  makes  part  of  the  large  '  Description  de  1'Egypte,'  and  to  which  in 
Engelmann's  Bibliotheca  Zoologica,  vol.  I,  p.  581,  the  date  1820  is  given. 
By  general  consense  the  date  of  publication  and  not  the  date  of  finishing 
a  manuscript  and  presenting  it  to  a  learned  body  is  accepted  as  fixing  the 
priority.  I  come  to  the  conclusion  that  Castalia  Lam.,  1819  can  stand 
for  the  shell,  and  Castalia  Sav.  among  the  Annelids  is  to  be  changed."

NOTES   UPON    THE   CHARACTERISTICS   AND   ORIGIN    OF 

THE    NON-MARINE   MOLLUSCAN   FAUNA   OF 

SOUTH   AMERICA.1 

In  the  following  synopsis  I  have  limited  myself  to  a  brief  consideration 
of  data  derived  solely  from  mollusks.  This  course  is  not  due  to  any 
underestimation  of  the  value  of  other  groups  in  biogeographic  work  ;  but 
rather  because  conclusions  drawn  from  a  group  known  to  me  at  first 
hand  have  a  certain  value  which  would  not  attach  to  borrowed  data.  The 
classification  used  herein  is  that  of  the  Manual  of  Conchology  so  far  as 
the  groups  have  been  considered  in  that  work.2 

It  must  constantly  be  borne  in  mind  by  those  comparing  the  distribu- 
tion of  non-marine  mollusks  with  that  of  vertebrate  groups,  that  not 
only  has  evolution  proceeded  more  slowly  in  the  former,  but  migrations 
have  been  slower.  Thus,  when  a  Pliocene  communication  was  established 
between  North  and  South  America,  there  was  a  rapid  and  extensive 
invasion  of  both  areas  by  mammals  ;  but  the  molluscan  invasion  was  very 
much  slower  and  never  extended  nearly  so  far.  Land  and  fresh-water 
mollusks  are  restrained  by  conditions  which  affect  mammals  and  birds  far 
less,  such  as  areas  with  little  forest,  unsuitable  or  very  scanty  rock  on  the 
surface,  or  short  river  systems,  not  well  connected. 

Any  inquiry  into  the  antecedents  of  a  fauna  leads  to  the  question  of 
where  its  component  groups  had  their  rise.  The  rarity  of  land  and  fresh- 
water shells  as  fossils,  and  the  great  antiquity  of  the  family  groups,  renders 
this  question  very  intricate.  The  origin  of  many  groups  is  still  quite  un- 
known ;  yet  most  of  the  larger  families  of  land-snails,  and  a  few  of  the 
fresh-water  groups  may  be  traced  back  with  considerable  certainty,  if  not 
to  definite  centers,  at  least  to  extensive  areas  of  evolution.

2  The  family  groups  of  land  snails  almost  all  differ  widely  in  contents  and  limits  from  those 
of  Fischer's  Manuel  and  other  systematic  works ;  a  fact  of  first  importance  in  dealing  with  the 
distribution  of  the  groups,  and  the  relationships  of  faunas.

—  reach  far  back  in  Palaeozoic  time.    We  have  no  data  bearing  upon  either 
the  time  or  place  of  these  events. 

I.  We  have  first  to  do  with  a  fauna  composed  mainly  of  the  Orthure- 
throus  land-snails1 — forms  which  are  structurally  but  a  step  removed  from 
the  aquatic  pulmonates,  and  now  forming  an  insignificant  element  in  conti- 
nental faunas,  though  still  dominant  in  the  islands  of  the  central  Pacific. 
The    families    ISalloniidce,    Enid<z,   Pupillidce,    PartnKd&%    Ferussacidce, 
Amastridcz,  Achatinellidce  and  Tornatellinidce  are  remnants  of  this  fauna, 
which  was  doubtless  once  nearly  or  quite  world  wide,  and  probably  attained 
its  acme  in  Palaeozoic  time.     The  Heterurethra  (Succineidce,  etc.)  doubt- 
less existed  in  this  early  fauna,  as  well  as  the  Aulacopoda  (EndodonticUz 
are  known  from  the  Carboniferous),  and  the  Helicinidce.     Of  the  fresh- 
water forms  probably  represented  in  this  fauna,   we  may  mention  the 
ancestral  stock  of  fresh-water  pearly  mussels,  the  Cyrenacea,  the  ancestral 
Melanopsidce  and  Melaniida,  and  the  Lymnceidce.     With  the  rise  of  the 
Sigmurethrous  snails,  the  land-snails  of  this  primitive  fauna  declined  in 
all  continental  areas. 

One  of  the  most  remarkable  features  of  the  South  American  fauna  is 
the  extreme  scarcity  of  these  primitive  Orthurethrous  land-snails.  This 
group  is  represented  only  by  a  few  Pupillidce  and  Ferussacidce,  probably 
derived  from  Middle  America  in  the  Tertiary,  and  closely  related  to  Antil- 
lean  and  Mexican  species. 

The  origin  and  early  differentiation  of  the  Sigmurethrous  land-snails  is 
unknown.  At  the  time  of  their  appearance  as  fossils,  in  the  late  Cretaceous 
and  Eocene,  the  modern  families  were  already  more  or  less  clearly  blocked 
out,  so  far  as  they  are  represented  by  known  fossils.  From  the  evidence 
at  hand,  derived  from  the  distribution  of  the  groups  in  the  recent  fauna, 
and  as  Cretaceous  and  Tertiary  fossils,  it  appears  that  the  evolution  of 
these  families  had  proceeded  during  Mesozoic  time  in  two  chief  areas,  for 
which  we  may  use  terms  proposed  in  another  connection  by  Dr.  Theodore 
Gill.

Eogaeic  or  Southern  origin,  but  there  are  also  northern  forms,  derived 
from  Middle  America  ("  Antillia"),  and  a  few  groups  of  ancient  and 
unknown  origin.  These  several  elements  are  as  follows.

development  in  the  Caenogaeic  faunas. 


614  PATAGONIAN   EXPEDITIONS  I     ZOOLOGY. 

Succineidce.     World-wide,  on  all  continents  and  islands. 
Chilinidce.     Autochthonous. 
Amnicolidce.     On  all  continents. 

The  ancestral  stocks  of  these  families  probably  formed  the  earliest 
fauna  of  non-marine  mollusks  in  South  America.  Some  of  the  families 
are  known,  in  other  regions,  to  have  been  established  in  Palaeozoic  times  ; 
and  it  is  likely  that  as  early  as  that  they  were  already  found  in  South 
America.  All  of  them  are  sharply  isolated  groups. 

The  Circinariidce  seem  to  have  remote  affinity  to  Rhytididce  and  Strep- 
taxidce —  both  of  which  evolved  in  the  southern  hemisphere  of  the  Old 
World.  In  North  America  this  family  is  probably  intrusive,  being  repre- 
sented by  a  single  genus  also  found  in  South  America. 

The  Strophocheilidce  have  relations — though  not  close — with  a  series 
of  genera  (Acavidce]  now  found  in  south  Africa,  Madagascar,  the  Sey- 
chelles, Ceylon,  Moluccas,  Australia  and  Tasmania.  The  radiation  of 
this  scattered  group  from  the  Palaeozoic  Gondwana  continent  of  Neumayr 
seems  a  reasonable,  in  fact  the  only  tenable,  hypothesis. 

The  BulfmuKda  have  descended  from  the  Holopod  stock,  probably 
also  of  Gondwana  Land,  since  we  have  no  evidence  of  any  other  ancestry. 

Endodontidce  and  Succineidce  are  world-wide  groups,  even  on  the  most 
remote  islands.  Their  early  presence  in  South  America  is  therefore  likely. 

The  Chilinidce  represent  an  isolated  branch  of  the  primitive  Basomma- 
tophora.  No  scrap  of  evidence  has  been  brought  to  light  to  show  that 
they  ever  existed  elsewhere  than  in  South  America  ;  and  at  present  we 
have  every  reason  to  believe  that  there  they  invaded  fresh  water  from 
the  sea. 

The  Pectinidens  group  of  Lymnceidce  and  the  Ancylidce  are  evidently 
traceable  to  some  very  early  radiation.  Adequate  data  upon  the  soft 
anatomy  and  relationships  of  the  forms  of  the  southern  hemisphere  do  not 
now  exist.

The  hypothesis  of  an  Africo-Brazilian  continent  of  Palaeozoic  and  Meso- 
zoic  times,  first  sketched  out  on  purely  palasontological  grounds,  and  ably

advocated  by  Dr.  von  Ihering  from  the  evidence  of  the  fresh-water  fauna, 
is  essential  to  any  rational  explanation  of  the  distribution  of  land  and 
fresh-water  mollusks. 

The  following  South  American  groups  are  common  to  the  tropical 
African  radiation  center.  Terrestrial  groups  are  marked  with  an  asterisk  (*). 

*  Streptaxidce  (fig.  21).' 
*•  Ackatinufo  (fig.  20). 

*  Veronicellidce. 

Planorbince  (South  American  Planorbis  and  Plesiophysa  close  to  African 

Planorbis  and  Isidord]. 

Ampullariidce  (genera  with  corneous  opercula,  fig.  22). 
Melaniidce  (nearest  to  African  forms). 
Mzttelidce  (fig.  23). 
Etheriidce  (fig.  24). 
Sphceriidce,  of  the  genus  Eupera. 

Such  of  these  groups  as  are  represented  in  the  West  Indies  and  sub- 
tropical North  America,  have  evidently,  from  their  distribution,  relation- 
ships and  the  greatly  diminished  number  of  genera  and  species,  been 
derived  from  South  America,  rather  than  from  some  common  source,  such 
as  Archhelenis.  None  of  them  are  present  as  Mesozoic  or  Tertiary 
fossils  in  North  America, x  and  nearly  all  of  them  are  likewise  absent  from 
European  deposits. 

There  is  a  good  deal  of  evidence  that  most  of  the  above  groups  arose 
in  the  eastern  hemisphere  and  migrated  westward,  and  little  evidence  or 
none  that  any  of  them  moved  in  the  opposite  direction. 

The  Streptaxidce,  Achatinidce^  Ampullariidce^  Melaniidcz  and  Mutelidce 
are  far  more  diversified  in  Africa  than  in  South  America.  It  seems  that 
several  Gondwana  subfamilies  were  not  present  in  the  fauna  of  Archhelenis, 
or  at  least  did  not  extend  so  far  west  as  to  reach  South  America,  though 
they  must  date  back  at  least  as  far  as  some  other  subfamilies  which  are 
represented  both  in  South  America  and  Africa. 

The  primitive  stock  of  fresh-water  mussels  seems  to  have  early  split  into 
two  phyla :  the  one,  Mutelidce,  evolving  in  the  south,  on  the  Gondwana- 
Archhelenis  continent,  the  other,  Unionidce,  in  the  north,  in  North  America 

1  The  Planorbincs  are  found  on  all  continents,  but  those  of  South  America  are  obviously  most 
closely  related  to  the  African  forms.

and  Asia.  The  occurrence  of  both  families  in  the  same  waters  is  evidently 
due  to  migrations,  which  ensued  after  the  families  had  become  differ- 
entiated. The  M^ltelid(Z  attain  their  northernmost  point  in  the  Panuco 
River,  in  northeastern  Mexico,  where  the  family  is  represented  by  one 
species  of  the  South  American  genus  Anodontites. 

Simpson  and  Germain  refer  a  few  African  forms  to  the  South  American 
genus  Diplodon,  and  Germain  has  called  attention  to  the  similarity  of  the 
African  Pseudamcula  to  the  South  American  Prisodon  or  Hyria.  If  the 
resemblance  of  the  shells  proves  to  be  supported  by  the  soft  anatomy, 
then  this  family  at  least  will  be  evidence  of  an  eastward  migration  in 
Archhelenis.  At  present  the  evidence  is  insufficient.  The  possibility  of 
convergence  in  shell-form  must  be  taken  into  account.  Most  if  not  all 
African  Unionidce,  like  the  African  Cyclostomatidce,  Zonitidce,  etc.,  are 
clearly  of  Oriental  derivation.  These  are  northern  Caenogaeic  families 
which  have  invaded  Africa  during  the  Tertiary. 

The  maps  following  illustrate  the  distribution  of  part  of  the  Archhelenic 

groups.

time.  Such  a  hypothesis  finds  support  in  the  presence  of  genera  of  the 
old  Brazilian  type  on  the  island  of  Fernando  Noronha.  Numerous  very 
peculiar  land-shell  genera,  such  as  those  tabulated  in  fig.  25,  have  a  dis- 
tribution not  readily  explicable  on  any  other  hypothesis ;  while  in  still 
other  cases,  allied  but  generically  distinct  groups  are  similarly  distributed. 
It  may  be  noted  that  Bates  has  remarked  that  the  Para  insect  fauna  is

That  the  Amazonian  valley  ever  formed  an  upper  Cretaceous  strait 
connecting  the  south  Atlantic  and  Pacific,  as  claimed  by  Dr.  Ortmann,2 
seems  rather  improbable. 

The  Guiana-Colombian  elevation  has  been  a  secondary  radiation  center  for 
a  number  of  genera  of  autochthonous  South  American  families,  chiefly  the

of  the  Amazon  into  eastern  Brazil  (fig.  28),  while  numerous  other  genera 
from  this  center  are  restricted  to  the  north  and  west  as  in  fig.  29.  The 
Guiana-Colombian  area  also  served  as  a  secondary  center  for  Antillean 
and  Mexican  groups,  entering  by  way  of  the  Caribbean  elevation  and  that 
in  the  Panamic  region.  These  groups  have  spread  southward  as  in 

figs.  30-34- 

A  hypothesis  has  been  advanced  by  Dr.  Ortmann3  that  Archhelenis  of 
the  Lower  Cretaceous  was  succeeded  in  the  Upper  Cretaceous  by  a  land 
bridge  from  tropical  Africa  to  an  area  covering  Guiana,  the  Caribbean  Sea 
and  the  Mexico-Antillean  region  (the  so-called  Mesozonia),  separated  from 
the  Brazilian  island.  By  this  hypothesis,  Antillia  should  be  as  rich  in 
African  or  Archhelenic  types  as  Brazil,  and  in  fact  should  show  a  closer 
resemblance  to  the  African  fauna  due  to  the  later  connection.  This  is

maps  incline  strongly  towards  what  Fiske  would  call  the  "wet  theory."     It  is  not  likely  that  all 
beds  reported  as  Upper  Cretaceous  were  below  the  sea  at  any  one  time.     To  map  an  Upper  Cre- 
taceous epicontinental  sea  to  include  all  the  exposures  of  a  formation  which  included  so  long  a 
period  of  time  is  not  warranted  by  our  present  slight  knowledge  of  the  stages  of  the  South 
American  Cretaceous.

exactly  contrary  to  the  actual  facts  of  molluscan  distribution.  All  African  or 
Archhelenic  forms  which  exist  in  the  Antilles  are  unequivocally  of  the  South 
American  type,  and  certainly  indicate  that  there  was  no  later  migration 
or  communication  from  Africa  in  the  north.  There  seems  little  evidence

1  The  belogonous  and  epiphallogonous  Helicidce  of  South  America  are  clearly  of  northern 
origin.  Whether  such  extremely  peculiar  genera  as  Solaropsis,  Psadara  and  Macrocydis  also 
belong  in  the  same  category,  seems  somewhat  uncertain,  although  such  competent  malacologists 
as  von  Ihering  and  Fritz  Wiegmann  place  these  genera  in  the  Epiphallogona. 

The  heavy,  large  Helices  of  the  Eocene  of  southern  Europe,  such  as  Deutellocaracolus,  Pro- 
thelidomus,  Galactocheilus  and  Fridolinia,  may  perhaps  belong  to  the  group  Epiphallogona  of  my 
arrangement,  rather  than  to  the  Helicinae  where  I  formerly  placed  them ;  yet  if  so,  I  think  the 
supposed  relationship  to  West  Indian  forms  is  not  especially  close.  Like  the  American  and 
European  species  of  Adelopoma,  the  Epiphallogona  probably  reached  both  Europe  and  America 
from  eastern  Asia,  and  from  opposite  directions. 

Dr.  von  Ihering  (Verhandlungen  k.  k.  zoologisch-botanischen  Gesellschaft  in  Wien,  LIX, 
1909,  pp.  420-428)  has  recently  referred  the  belogonous  Helices  (Epiphragmophora)  of  Argen- 
tina and  southern  Brazil  to  the  European  genus  Helicigona  (Campyltea  auct.) ;  but  I  do  not 
believe  that  this  classification  can  be  sustained.  So  far  as  I  know,  the  South  American  Epiphrag- 
mophoras  have  the  spermathecal  duct  very  short,  whereas  Helicigona,  like  all  other  European 
Belogona,  has  a  very  long  duct,  bearing  a  long  diverticulum,  which  is  bound  by  a  membrane  to 
the  oviduct.  These  are  important  differences,  quite  sufficient  to  show  that  Epiphragmophora  is 
not  at  all  closely  related  to  Helicigona,  aside  from  the  different  shape  of  the  mucous  glands,  and 
their  removal  in  Epiphragmophora  from  the  vagina,  upon  which  they  are  invariably  inserted  in  all 
European  Belogonous  Helicidce, 

By  its  short  spermatheca,  Epiphragmophora  differs  strongly  from  all  other  known  belogonous 
Helicidce.  In  other  features  it  stands  nearer  to  Antillean  and  North  American  forms  than  to 
European.  My  former  treatment  of  the  genus  was  too  inclusive.  I  would  now  restrict  Epiphrag- 
mophora to  forms  having  the  spermatheca  short,  removing  all  of  the  Mexican  and  North  Amer- 
ican species  (which  have  a  long  spermathecal  duct)  from  the  genus.

the  Caribbean  Islands  on  the  east,  and  on  the  west  the  region  of  the  Isthmus 
of  Panama,  where  the  interchange  of  forms  has  continued  to  the  present 
time.  That  the  middle  American  elements  are  far  younger  in  South 
America  than  the  Archhelenic,  is  shown  by  their  close  relationships  to 
Antillean  and  Mexican  forms,  very  few  special  genera  having  evolved.  In

most  of  the  families  only  one  or  very  few  genera  have  invaded  South 
America  out  of  a  large  number  in  the  parent  lands.  Moreover,  it  is  notable 
that  they  have  not  extended  far  south  in  the  east,  where  the  Amazon 
valley  has  proved  a  barrier  to  land-snails.  Their  distribution  has  been 
along  the  Andes,  spreading  eastward  in  Bolivia  and  southern  Brazil.

In  molluscan  distribution,  there  is  strong  evidence  against  the  view 
of  Ortmann  (1902,  p.  347)  that  the  northern  margin  of  South  America 
formed  part  of  the  Antillean  continent.  Schuchert's  representation  of  the 
Caribbean  Sea  as  an  old  permanent  basin  seems  preferable ;  but  his  repre- 
sentation of  the  total  submergence  of  the  Antilles  in  the  Middle  Cretaceous

and  again  in  the  Upper  Oligocene1  cannot,  I  think,  be  sustained.  The 
rich  Oligocene  beds  of  Jamaica  (Bowden)  and  Santo  Domingo,  carrying 
a  marine  fauna  of  littoral  type,  occur  at  very  low  levels ;  and  no  deposits 
actually  known  to  be  Oligocene  are  found  on  the  higher  mountains,  which 
I  believe  were  islands  in  both  Cretaceous  and  Oligocene  times. 

The  primary  region  of  radiation  of  the  middle  American  families  named 
above  is  a  subject  too  large  for  adequate  discussion  in  this  place.  So 
much  is  clear :  the  fauna  contains  three  groups  of  diverse  genesis.  The

land-mollusk  evolution.  Some  of  them,  and  the  ancestors  of  all,  doubtless 
had  a  much  wider  range  in  Mesozoic  times.  A  few,  such  as  the  Oleacin-

idee  and  Cyclostomatidcs,  were  abundantly  developed  in  Europe  as  late  as 
the  Miocene,  or  even  linger  in  a  few  forms  in  the  recent  fauna.  These 
European  forms  cannot,  in  my  opinion,  be  looked  upon  as  ancestral  to  the 
Antillean,  but  rather  as  parallel  descendants  of  a  common  stock  derived 
from  the  north,  where  the  old  Scandinavian  and  North  American  land 
areas  were,  at  least  from  time  to  time,  united. 

A  second  element  of  the  Mid-American  lands  consists  of  groups  derived 
from  the  Chinese  or  east-Asiatic  center.  Prominent  members  are  the 
dart-bearing  and  the  Epiphallogonous  Helicidce,  the  Cyclophoridcz,  Dip-

lommatinidce  (Adelopoma],  Clausiliidce,  etc.  These  forms  never  have  the 
old-age  stigmata  of  the  preceding  group.  They  are  developed  in  won- 
derful abundance  and  virility.  Being  known  in  characteristic  genera  of 
American  type  (Pleurodonte,  Cepolis]  in  the  Floridian  Oligocene  island,  the 
advent  of  the  group  in  middle  America  must  have  been  much  earlier.  It 
could  hardly  have  been  later  than  the  beginning  of  the  Eocene,  and  prob- 
ably was  not  later  than  the  Upper  Cretaceous.1 

Finally,  we  have  as  the  latest  faunal  element  in  the  Antillean-Mexican 
area,  a  series  of  South  American  forms  —  Achatinidce,  Bulimulidce, 
Ampullariidce,  Melaniidcz,  Mutelidce  and  some  North  American  forms, 
Unionidce,  Pupillida,  Zonitidce,  Polygyrince,  etc.  These  are,  with  very  few 
exceptions,  unchanged  generically,  and  some  are  specifically  identical  with 
existing  South  or  North  American  forms.  It  is  very  evident  that  such 
Archhelenic  forms  as  exist  in  the  Antilles  and  Mexico  were  not  derived 
directly  from  the  Archhelenic  area ;  they  migrated  in  the  later  Tertiary 
and  Pleistocene  from  the  Guiana-Colombian  center. 

Antillia  has  not  been  an  evolution  center  for  fresh-water  mollusks  or 
fishes,  evidently  because  it  has  never  been  a  very  large  area,  and  has  been 
an  unstable  one,  at  one  time  in  form  of  a  continent,  again  an  archipelago, 
hence  without  river  systems  of  great  extent  or  duration,  such  as  are  essen- 
tial to  the  evolution  of  a  fresh-water  fauna. 

There  is  absolutely  nothing  in  the  distribution  of  mollusks  suggesting 
that  either  South  or  North  America  was  at  any  time  connected  with  the 
supposed  South  Pacific  continent,  or  the  Hawaiian  group.  Even  Juan 
Fernandez  has  a  land-snail  fauna  of  Pacific  and  not  South  American  type. 
The  Hawaiian  and  Polynesian  connections  with  America  mapped  by  Arldt 
(1907)  seem  quite  impossible. 

1  The  American  Clausiliidcz  are  thought  by  Professor  Boettger  to  be  related  to  the  European 
Miocene  and  recent  Pyrenean  group  Laminifera,  but  they  seem  to  me  even  closer  to  the  genus 
Garnieria,  of  the  Indo-Chinese  center.  The  Helicinidce  may  have  arisen  in  Middle  America  from 
an  aquatic  rhipidoglossate  stock,  but  the  very  wide  distribution  of  the  group  in  Polynesia  and 
eastern  Asia  suggests  that  it  is  a  very  old  one,  which  probably  appeared  among  the  first  land- 
snails. 

The  Belogonous  Helices  still  exist  in  high  latitudes  on  both  sides  of  the  Pacific,  being  known 
from  Sitka  on  the  American  and  the  Kuril  Islands  on  the  Asiatic  side.

ARCHIPLATA   AS   AN    EVOLUTION-CENTER. 

Wallace  in  I8761  showed  that  the  South  American  fauna  is  divisible 
into  two  subregions  which  he  called  the  Tropical  or  Brazilian  and  the 
South  Temperate  or  Chilian.  He  calls  attention  to  the  affinities  of  the 
Chilian  diurnal  Lepidoptera  and  the  Carabidae  to  North  Temperate  forms.2 
Dr.  H.  von  Ihering  in  numerous  papers 3  has  recognized  the  two  subregions 
of  Wallace  as  distinct  evolution  centers.  He  concludes  that  these  centers, 
Archiplata  (that  is,  Patagonia,  southern  Brazil,  Chili  and  western  Peru)  and 
Archibrazil,  were  long  isolated  from  one  another  by  an  arm  of  the  sea.  As 
primitive  elements  of  the  Archiplatan  fauna  he  mentions  the  fresh-water 
crab  sEglea,  the  genus  Parastacus,  and  the  mollusks  Diplodon  and  Chilina. 
Negative  characteristics  are  found  in  the  absence  of  the  dominant  Ama- 
zonian genera  of  mussels  and  Ampullariidcz  (which  seem  to  have  invaded 
the  La  Plata  drainage  area  comparatively  lately,  probably  in  the  Pliocene) 
to  which  many  groups  of  land-snails  might  be  added. 

The  geology  of  the  regions  involved  is  so  imperfectly  known  that  we 
have  no  positive  data  for  or  against  the  hypothesis  that  an  arm  of  the 
Cretaceous  sea  extended  across  the  continent,  as  von  Ihering  claims.  This 
is  a  question  only  to  be  settled  by  geological  exploration  of  the  region, 
which  may  perhaps  show  a  Cretaceous  transgression  similar  to  that  which 
involved  eastern  Mexico  and  the  region  northward  in  the  middle  Cretaceous. 
Yet  the  fact  remains  that,  so  far  as  molluscan  groups  are  concerned,  there  is 
but  little  evidence  of  such  an  isolation  of  the  Archiplatan  area.  The  barriers 
to  migration  imposed  by  climate  have  not  been  taken  into  account.  The 
AmpitllariidcB  are  snails  that  have  never,  in  any  region,  been  able  to  extend 
beyond  a  subtropical  climate.  TheGb&Kttfe  (fig.  36)  are  apparently,  like 
the  large  Lymnaeas  in  North  America,  snails  which  cannot  exist  in  a  sub- 
tropical or  even  a  warm  temperate  environment,  however  favorable  maybe 
the  conditions  of  migration.  It  is  instructive,  in  this  connection,  to  com- 
pare the  Lymnaeid  faunas  of  Minnesota  and  Arkansas,  which  show  great 

1  Geographical  Distribution  of  Animals,  II,  frontispiece  and  Chapter  XIV. 

1  Dr.  Scharff  has  suggested  an  explanation  of  this  peculiarity  (American  Naturalist,  Septem- 
ber, 1909,  p.  5  13),  but  his  hypothesis  explains  only  a  few  facts.  It  would  involve  us  in  problems 
more  intricate  than  those  which  it  solves.  Possibly  the  systematic  relations  of  the  insects  in 
question  have  not  been  rightly  estimated.

notis,"  Leipzig,  1907.

diversity,  although  favorably  situated  for  migration. 1  Another  group  which 
is  widely  distributed  in  the  Archiplatan  area,  though  not  confined  to  it,  is 
the  Amnicolid  genus  Littoridina  (fig.  35).  The  absence  of  Amnicolidae 
in  the  Amazon  system  is  probably  apparent  rather  than  real,  since  prac- 
tically no  collecting  of  small  or  minute  mollusks  of  any  kind  has  been 
done  in  that  vast  area.  It  is  likely  that  Amnicolidae  will  be  found  there

in  abundance.  Diplodon,  another  genus  which  Dr.  von  Ihering  considers 
Archiplatan,  is  found  almost  all  over  the  continent,  and  cannot  fairly 
becl  aimed  as  of  Archiplatan  origin.  It  no  doubt  arose  from  the  same 
Brazilian  (and  ultimately  Archhelenic)  stock  as  Hyria,  etc.;  but  like  Unio 
in  the  northern  hemisphere,  it  is  a  hardy  stock  not  highly  evolved  in  its 
phylum,  hence  probably  old.  Compare  in  this  connection  the  Unionid 
and  Pleuroceratid  fauna  of  Alabama  with  that  of  Georgia  and  the  Caro- 
linas.  In  these  adjacent  areas,  which  have  been  continuous  land  since 
very  early  times,  we  have  as  much  difference  in  the  fresh-water  faunas  as 
has  been  shown  to  exist  between  Archibrazil  and  Archiplata.  Rich  faunas 
of  fresh-water  mussels  and  gastropods  are  rarely  found  in  regions  like 

1  At  Davenport,  Iowa,  I  have  found  Lymncea  stagnalis  on  logs  rafted  down  the  river  from 
Minnesota,  but  the  species  has  not  been  able  to  gain  a  place  in  this  fauna  there  or  farther  south  ; 
nor  have  many  of  the  other  northern  Lymnaeidse,  which  must  yearly  be  brought  down  on  drift 
wood  during  the  spring  floods.

southern  South  America,  drained  by  numerous  short,  independent  rivers, 
owing  to  the  difficulty  of  migration  and  the  relative  impermanence  of  the 
individual  streams. 

The  presence  of  peculiar  and  strongly  individualized  land  snails  of 
Brazilian  type  (Scalarinella,  Plagiodontes,  etc.)  in  the  Sierras  of  western 
Argentina  and  the  now  isolated  Sierra  Ventana,  shows  that  long  ago  the 
Brazilian  fauna  extended  at  least  as  far  south  as  Bahia  Blanca,  where  a 
fragment  has  persisted,  isolated  since  the  Pliocene  at  least.1 

Taking  into  consideration  the  climate,  the  rarity  of  large  forest  areas, 
the  aridity  of  large  tracts,  and  the  short,  unconnected  rivers,  we  are  not 
inclined  to  give  much  weight  to  Dr.  von  Ihering's  contention  that  many 
Brazilian  groups  are  wanting  in  "  Archiplata."  So  far  as  mollusks  are 
concerned,  that  area  has  very  slight  claims  to  rank  as  an  evolution  center. 
I  regard  the  Chilian  and  Patagonian  fauna  as  an  impoverished  and  slightly 
modified  extension  of  the  fauna  of  the  old  Brazilian  continent.  The  evi- 
dence for  an  Archiplatan  center  may  be  stronger  in  the  case  of  Crustacea, 
Oligochaeta,  plants  and  insects  ;  but  I  prefer  to  leave  the  discussion  of 
these  groups  to  those  having  first-hand  knowledge  of  them. 

Connected  with  the  Archiplata  hypothesis  is  that  of  Antarctica,  which 
may  here  be  examined  briefly. 

AUSTRAL  ELEMENTS   IN   THE   SOUTH   AMERICAN 

FAUNA. 

The  Austral  or  Antarctic  relationships  of  the  South  American  fauna 
have  been  somewhat  fully  discussed  in  other  volumes  of  this  series,  and 
a  map  illustrating  the  Antarctic  continent  and  its  hypothetical  former  ex- 
tensions may  be  found  in  volume  IV.  I  have  to  deal  here  with  the  evi- 
dence afforded  by  the  non-marine  mollusks,  which,  taken  by  itself,  leads  to 
the  following  conclusions  :  ( i )  There  is  no  evidence  that  Antarctica  was 
ever  an  evolution  or  radiation  center  for  non-marine  mollusks,  though 
there  is  some  evidence  showing  that  it  served  as  a  highway  for  migration. 

(2)  There  is  some  evidence  of  migration  from  South  America  to  Austral- 
asia, but  at  present  no  evidence  of  a  counter  movement  to  South  America. 

(3)  Nothing  in  the  distribution  of  mollusks  would  lead  to  the  hypothesis 

1  Dr.  Ortmann  agrees  with  von  Ihering  in  isolating  a  Chilian  and  southern  Patagonian  land 
mass  of  Cretaceous  age,  but  he  views  it  as  an  extension  of  Antarctica.  The  difference  is  rather 
one  of  names  than  of  things.  Proc.  Amer.  Philos.  Soc.,  1902,  pp.  379,  381. 


630  PATAGONIAN    EXPEDITIONS!     ZOOLOGY. 

that  South  Africa  has  ever  been  connected  with  Antarctica  and  thereby 
indirectly  with  southern  South  America. 

Non-marine  mollusks  having  an  Antarctic  distribution  belong  to  three 
families.  The  evidence  in  each  case  is  briefly  as  follows  : 

i.  The  Bulimulidce,  land  snails  of  South  American  origin,  of  which  one 
genus  (Bothriembrion)  is  found  in  Tasmania  and  southwestern  Australia, 
another  (Placostylus]  in  New  Zealand,  New  Caledonia,  the  islands  of 
Melanesia  and  as  far  east  as  Fiji.  Both  of  these  genera  are  distinct  from 
South  American  forms,  but  they  are  undoubtedly  related  to  the  more 
generalized  of  the  South  American  genera. 

FIG.  37. 


Distribution  of  the  land  snail  family  Bulimulidae.  The  number  of  genera  in  each  area  is  indi- 
cated by  figures. 

The  presence  of  Bulimulidce  in  Australia  and  Melanesia  proves  that 
the  part  of  South  America  connecting  with  Antarctica  was,  or  had  been, 
connected  with  the  old  Brazilian  evolution  center. 

2.  The  Amnicolidce,  a  family  of  fresh-water  snails,  has  one  genus, 
Potamopyrgus,  in  New  Zealand,  Tasmania  and  South  America.  Another 
South  American  genus,  Pofamoltikus,  has  its  nearest  ally  in  the  genus 
Petterdiana  of  Tasmania  and  Australia.  Both  of  these  genera  are  exclu- 
sively fresh-water  groups.  See  pp.  548-550  of  this  report. 


PILSBRY:    NON-MARINE  MOLLUSCA  OF  PATAGONIA.  631 

3.  The  Naiades  or  fresh-water  mussels  found  in  all  of  the  continents,  are 
represented  in  Australia,  Tasmania  and  New  Zealand  only  by  species 
which  have  been  referred  to  the  genus  Diplodon.  This  genus  is  widely 
distributed  in  South  America,  especially  southward.  It  is  a  relatively 
primitive  genus  and  probably  arose  in  South  America,  which,  from  the 
number  of  autochthonous  genera,  was  evidently  an  old  evolution  center 
of  Naiades.  Diplodon  is  unknown  in  the  northern  continents.  Whether 
the  relationship  with  South  American  forms  claimed  for  the  Australia- 
New  Zealand  group  is  well-founded,  remains  to  be  confirmed  by  careful 
comparison  of  the  soft  anatomy. 

The  family  Endodontidce,  and  Gundlachia  of  the  Ancylidce,  have  been 
considered  "Antarctic"  groups,  but  on  evidence  of  slight  value.  The 
Endodontidce  are  an  ancient  group,  world-wide  in  distribution.  No  close 
relationship  has  been  shown  to  exist  between  the  South  American  and 
the  Australian  genera.  The  former  are  unknown  anatomically,  and  the 
relations  of  Australian  and  New  Zealand  forms,  so  far  as  positively  made 
out,  are  with  the  groups  of  Polynesia  and  Micronesia  (Charopa,  Thattma- 
todon,  etc.).  Certain  Tasmanian  species  may  prove  to  belong  to  the 
American  genus  Radiodiscus  Pils.  See  p.  516. 

Gundlachia  is  found  in  Australasia,  South  America,  the  Antilles,  Mexico, 
temperate  North  America  and  also  the  Miocene  of  central  Europe.  This 
wide  distribution  suggests  that  the  genus  may  have  reached  the  southern 
lands  from  the  north.  In  the  United  States  it  has  been  found  in  Cali- 
fornia, Illinois,  Ohio,  New  York,  etc.,  but  only  at  remote  intervals  and  in 
very  narrowly  restricted  areas.  It  is  likely  that  it  will  turn  up  sooner  or 
later  in  the  Oriental  region  and  Africa.  I  hesitate  to  claim  Gundlachia 
as  an  inhabitant  of  Antarctica. 

Pond  snails  of  the  family  Lymnceidce  also  occur  in  all  the  Austral 
lands,  but  South  American  forms  do  not  seem  especially  related  to  Austral- 
asian. While  Endodontidce,  Gundlachia  and  Lymncea  may  have  inhabited 
Antarctica,  no  data  upon  them  now  in  our  possession  goes  far  towards 
proving  that  they  did. 

I  can  find  no  evidence  to  support  Hedley's  contention  that  the  Macro- 
ogona  (Acamdce]  of  Tasmania  and  Australia,  and  the  Rhytididce  of  the 
same  regions,  New  Zealand,  New  Caledonia,  etc.,  are  "of  Antarctic  origin."1 
These  groups  must  have  attained  their  distribution  from  South  Africa  to

Australia  by  way  of  the  Gondwana  continent,  leaving  isolated  genera  by 
the  way  in  Madagascar,  the  Seychelles,  Ceylon  and  the  Moluccas.  To 
this  Palaeozoic  and  early  Mesozoic  land  the  South  African  Endodontidce, 
Peripatus,  etc.,  may  also  belong.  The  evidence  for  an  isthmus  connecting 
South  Africa  and  Antarctica,  as  sketched  by  Forbes,  Ortmann  and  some 
other  palaeogeographers,  seems  unsubstantial.  Nothing  in  the  distribution 
of  non-marine  mollusks  lends  it  support.

The  rather  large  size  of  the  fresh-water  mussels  and  Bulimulidce  pre- 
cludes the  idea  of  their  distribution  as  adult  organisms  except  by  actual 
land  connection.  Some  embryonic  Unionidce  are  probably  carried  by  water 
birds,  but  we  do  not  know  that  this  is  the  case  with  Diplodon;  moreover 
only  short  distances  can  be  so  traversed,  since  unionid  embryos  are  known 
to  die  quickly  out  of  water.  It  is  hardly  conceivable  that  Bulimulid  eggs, 
which  are  smooth  and  not  viscid,  should  be  so  carried.  The  same  is  true

of  the  egg-capsules  of  Amnicolidcz.  It  would  be  absurd  to  suppose  that 
they  could  ever  be  spread  by  aquatic  birds. 

Such  evidence  as  we  have  favors  the  view  that  the  connection  of  South 
America  with  Antarctica  was  transitory,  hence  taken  advantage  of  by  but 
few  genera  of  mollusks,  all  belonging  to  families  richly  developed  in  the 
South  American  center.  So  far  as  non-marine  mollusks  show,  the  migra- 
tion from  South  America  of  a  few  species  belonging  to  three  families  will 
account  for  all  the  common  elements  in  the  austral  lands  of  the  two 
hemispheres.  The  strong  generic  differentiation  of  all  the  common 
austral  groups,  with  the  exception  of  Potamopyrgus  and  probably  Diplo- 
don,  indicates  that  the  connection  was  of  considerable  antiquity,  probably, 
as  Dr.  Ortmann  holds,  not  later  than  Eocene. 

Summary. — The  South  American  molluscan  fauna  is  traceable  to  two 
sources  :  an  ancient  southern  continent  lying  across  the  south  Atlantic 
and  enduring  from  at  least  Palaeozoic  to  near  the  end  of  Cretaceous  time, 
and  to  Miocene  and  Pliocene  to  recent  connections  with  the  middle 
American  area.  Antarctica  was  not  an  evolution  center  for  mollusks,  but 
there  is  strong  evidence  that  a  few  groups  passed  by  the  Antarctic  route 
to  Australasia.  "  Archiplata,"  owing  to  its  physical  diversity  from  the 
Brazilian  and  Colombian  areas,  has  became  a  Tertiary  evolution  center 
for  a  few  groups  of  Brazilian  origin. 

Middle  America  (Antilles  +  Central  America  and  part  of  Mexico)  has 
the  characteristics  of  an  old  evolution  center  of  the  northern  faunal 
group,  its  primitive  fauna  coming  from  the  north,  and  now  showing  phylo- 
gerontic  features ;  a  later  (probably  late  Cretaceous)  element  was  derived 
from  the  East  Asiatic  fauna.  Both  elements  contributed,  during  the  last 
half  of  the  Tertiary,  to  the  South  American  fauna,  and  received  immi- 
grants in  return. 

The  "  Nearctic  Realm,"  so  far  as  the  genesis  of  its  faunas  is  concerned, 
is  composite.

LETTER  OF  TRANSMITTAL. 

Sir  : 

I  have  the  honor  to  transmit  herewith  the  report  on  the  recent  Crus- 
tacea collected  in  Patagonia  by  Mr.  J.  B.  Hatcher. 

The  collection  is  a  small  one,  and  contains,  of  marine  forms,  only  such 
as  are  more  or  less  well  known,  adding,  however,  for  some  of  them  new 
localities  on  the  eastern  coast  of  Patagonia,  a  region  that  scarcely  has  been 
properly  investigated. 

The  most  valuable  part  of  the  collection  consists  of  freshwater  Crus- 
taceans found  by  Mr.  Hatcher  in  the  interior  of  southern  Patagonia :  among 
them  are  several  very  important  new  and  rare  species. 

Very  respectfully,  your  obedient  servant,

INTRODUCTION. 

The  collections  of  Crustaceans  made  by  Mr.  J.  B.  Hatcher  in  southern 
Patagonia  are  partly  marine,  partly  freshwater.  The  following  are  locali- 
ties from  which  marine  forms  have  been  secured  :  they  are  all  close  to  the 
shore,  in  shallow  water,  and  are  situated  —  with  the  exception  of  the  first 
—  on  the  eastern  coast  of  Patagonia.

2.  Gallegos,  at  the  mouth  of  the  Gallegos  River,  South  Patagonia.

Freshwater  material  has  been  collected  at  numerous  localities  in  the 
interior.  This  has  been  numbered  by  Mr.  Hatcher  according  to  stations, 
and  the  character  and  description  of  each  station  is  given  in  the  text 
under  each  species.  All  these  stations  are  situated  in  the  region  of  the 
Rio  Chico  (northern  tributary  of  the  Santa  Cruz  River),  from  near  the  ocean 
up  to  the  foothills  of  the  Cordilleras,  in  47-50°  S.  The  localities  Sierra 
Oveja  and  Sierra  Ventana  are  on  the  Rio  Chico.  Arroyo  Gio  is  in  the 
foothills  of  the  Cordilleras.1  The  highest  altitude  at  which  specimens 
were  obtained  is  at  about  2,000  feet.

PSEUDOBOECKELLA  Mrazek. 

The  original  genus  Boeckella  of  Guerne  and  Richard  (1889,  p.  151), 
created  for  the  preoccupied  Boeckia  of  Thomson  (1883)  was  divided  by 
Mrazek  (1901)  and  von  Daday  (1902)  into  several  genera.  Of  course, 
Mrazek's  names  have  the  priority.  Unfortunately  both  divisions  do  not 
completely  agree,  and  the  names  chosen  by  either  author  are  apt  to  give 
origin  to  confusion.  Generally,  we  may  say  that  Pseudoboeckella  of 
Mrazek  corresponds  to  Boeckella  of  v.  Daday,  and  vice  versa,  although 
Mrazek  puts  B.  bergi  Rich,  into  a  separate  genus  (Boeckellopsis],  while  it 
is  included  in  v.  Daday's  Pseudoboeckella;  and  although  B.  brevicauda 
Brad.,  which  is  included  in  v.  Daday's  Boeckella,  forms  the  genus  Para- 
boeckella  of  Mrazek. 

The  two  species  mentioned  here  have  been  described  by  v.  Daday  under 
Boeckella  (sens,  strict.),  and  seem  to  belong  to  Pseudoboeckella  of  Mrazek.

Locality.  —  First  water  hole  north  of  basalt  ridge,  50  miles  from  Rio

about  47-48°  S.) 

Description. —  Scutum  large,  suboval,  emarginate  behind,  covering  about 
two  thirds  of  the  body.  Of  the  abdomen,  9  or  10  segments  (including 
telson)  are  uncovered.  Eyes  elliptic,  closely  approaching  one  another  in

front,  diverging  behind.  First  cervical  furrow  almost  straight,  second  one 
strongly  curved  backward  in  the  middle,  and  slightly  shallower  in  the 
middle,  but  distinct.  Median  keel  indistinct  anteriorly,  very  distinct  pos- 
teriorly. Lateral  margins  smooth,  only  near  the  posterior  corners,  for  a 
short  distance,  very  finely  crenulated.  Posterior  emargination  with  small, 
somewhat  irregular  spinules,  the  median  one  (end  of  median  keel)  the 
largest.  Supra-antennal  keel  slightly  sinuate,  apparently  smooth,  but 
under  the  lens  there  are  fine  and  minute  granulations. 

Flagella  of  first  pair  of  feet  short,  unequal,  slightly  depressing  the  margins 
of  the  scutum.  Free  abdominal  segments  spinulose,  about  6-8  spinules 
on  upper  side  ;  these  are  larger,  straight,  and  arranged  somewhat  irregu- 
larly ;  those  of  the  ventral  side  are  smaller,  numerous. 

Telson  (fig.  ib]  on  upper  side,  near  base  of  cercopoda,  on  either  side 
with  a  small,  spinulose  tubercle.  Caudal  flap  elongate,  over  twice  as  long 
as  wide  at  the  base,  with  parallel  margins,  sublanceolate  at  the  end  and 
rounded  ;  distal  half  of  margin  spinulose,  with  the  strongest  spinule  at 
the  end.  Upper  surface  with  a  median,  longitudinal  keel  bearing  four 
strong  spinules. 

Cercopoda  almost  as  long  as  the  rest  of  the  body,  thickly  covered  with 
bristles. 

Color  deep  green,  lower  parts  pale  greenish,  mandibles  brownish. 

Size  :  Length  of  body  40  and  46  mm.  Total  length  of  larger  indi- 
vidual (including  cercopoda),  77  mm. 

Remarks. — At  first  there  seemed  to  be  no  doubt  to  me  that  our  speci- 
mens ought  to  be  referred  to  L.  patagonicus  Berg  (1900),  which  comes 
from  near  the  same  region  (Territ.  of  Chubut),  but  a  careful  comparison 
of  our  specimens  with  Berg's  description  reveals  the  following  dis- 
crepancies : 

1.  Of  the  abdomen,  only  10  segments  are  exposed  in  our  species,  while 
in  L.  patagonicus  15-16  are  seen.    Thus  the  abdomen  of  the  latter  appears 
to  be  longer. 

2.  In  L.  patagonicus  the  eyes  are  said  to  be  suboval,  and  not  to  approach 
one  another  anteriorly,  while  in  our  species  they  are  elliptic  and  distinctly 
convergent  in  front. 

3.  The  lamina  caudalis,  in  L.  patagonicus,  is  one  third  longer  than 
broad ;  in  our  species  it  is  distinctly  more  than  twice  as  long  as  broad. 
This  is  the  most  striking  difference.     Through  the  kindness  of  Mr.  A.  J. 


642  PATAGONIAN    EXPEDITIONS  I     ZOOLOGY. 

Pendola  of  the  museum  in  Buenos  Aires,  I  possess  sketches  of  the  caudal 
flap  of  Berg's  species,  which  show  that  it  is  only  very  slightly  longer  than 
broad. 

4.  There  seems  to  be  more  of  a  ferrugineous  color  on  the  lower  side 
of  the  body  in  L.  patagonicus. 

5.  The  size  of  L.  patagonicus  is  smaller,  body  30-35  mm.,  and  includ- 
ing cercopoda,  43-46  mm.,  while  our  species,  without  cercopoda,  reaches 
46  mm. 

Berg  describes  a  male,  while  our  specimens  are  females,  but  I  hardly 
believe  that  the  above  differences  are  due  to  sex,  since  it  is  characteristic 
in  this  family  that  $  and  9  hardly  differ,  except  for  the  smaller  size  of 
the  J1,  and  the  larger  caudal  flap  of  the  tf.  While  the  first  character 
would  apply  to  this  case,  the  second  does  not,  the  caudal  flap  being  much 
larger  in  our  9-  On  the  other  hand,  the  longer  abdomen  in  the  J1  would 
agree  with  the  same  condition  found  in  the  J1  of  L.  bilobatus. 

For  the  rest,  our  species  resembles  L.  angasi  Baird  (1866,  p.  122,  pi. 
12,  f.  i)  from  South  Australia  (Adelaide).  Here  the  general  form  of  the 
body  and  the  characters  of  the  various  parts  are  almost  identical,  and  I 
find  only  the  following  differences  : 

1.  L.  angasi  is  much  smaller  (i  inch  =  25  mm.). 

2.  The  body  is  of  horn-color  instead  of  green. 

3.  The  spinules  of  the  abdomen  are  curved  downward  in  L.  angasi, 
while  they  are  straight  in  our  species. 

In  all  other  respects,  both  species  are  closely  allied,  especially  the  fol- 
lowing important  characters  agree : 

1.  Number  of  exposed  abdominal  segments  :   12  in  L.  angasi  (accord- 
ing to  figure),  10  in  our  species. 

2.  Eyes  of  the  same  size  and  shape  (according  to  figure  of  L.  angasi}. 

3.  Keel  of  scutum,  and  fine  dentations  on  posterior  part  of  lateral 
margins  similar  in  both. 

4.  Cervical  furrows  identical  (according  to  figure  of  L.  angasi}. 

5.  Caudal  flap  absolutely  identical  in  form,  but  it  seems  that  the  margins 
are  denticulated  all  around  in  L.  angasi. 

The  apparently  close  affinity  of  our  species  with  the  South  Australian 
L.  angasi  demands  an  investigation  of  the  relationship  of  it  with  the  other 
known  species  of  the  genus,  and  we  may  state  the  following : 

i.  L.  glacialis  (Kr.)  (see  Simon,  1886).    Arctic  regions. 


ORTMANN:   CRUSTACEA  OF  SOUTHERN  PATAGONIA.  643 

For  a  comparison  with  our  species  this  is  out  of  the  question,  on  ac- 
count of  the  short  flagella  of  the  first  legs,  and  the  very  short  caudal  flap. 

2.  L.  lubbocki  (Brauer),  from  Sicily  and  Algiers,  and  L.  macrurus  Lilj. 
from  Archangel,  Russia  (see  Simon,  1886),  have  a  carina  of  the  scutum 
that  is  sharp  from  its  beginning  at  the  second  cervical  furrow  down  to  the 
hind  margin.     These  two  species  are  closely  allied  to  L.  apus  (L.)  from 
Europe  (see  below),  which  is  in  some  degree  related  to  our  species,  but 
just  in  the  character  mentioned  here  they  deviate  more  considerably  from 
L.  hatcheri,  than  L.  apus  does. 

3.  Of  the  North  American  species  (see  Packard,   1883),  L.  bilobatus 
Pack,  from  Colorado  is  entirely  different  in  the  bilobate  caudal  flap  and  the 
longer  abdomen  (12  segments  exposed  in  the  cT,  16  in  the  $).     L.  couesi 
Pack,  from  Montana  and  Utah  differs  in  the  much  shorter  abdomen,  and 
the  longer  and  distinctly  spatulate  caudal  flap.     L.packardi  Simon  (1886, 
p.  448)  from  California  differs  at  once  in  the  very  short  abdomen,  in  the 
second  cervical  furrow,   which  is  interrupted  in  the  middle,  and  in  the 
median  keel  of  the  caudal  flap,  which  has  7-8  spines. 

4.  Of  the  other  Australian  species  (aside  from  L.  angasi],  L.  viridis 
Baird  (1850,  p.  254,  pi.  17,  f.  i)  from  Tasmania  has  a  distinct  carina  of 
the  scutum,  and  the  caudal  flap  is  oval  (narrower  at  the  base).     L.  mridu- 
lus  Tate  (1876,  p.  136,  and  Brady,  1886,  page  88,  textfig.  E)  from  Ade- 
laide has  the  abdomen  very  short,  and  the  caudal  flap  is  distinctly  spatu- 
late. 

5.  The  two  New  Zealand  species,  L.  kirki  and  compressus  Thomson 
(1879,  p.  260,  pi.   n,  f.  4,  5)  are  also  distinctly  different:  in  L.  kirki  a. 
much  larger  part  of  the  abdomen  is  covered,  and,  although  the  caudal 
flap  resembles  somewhat  that  of  L.  hatcheri,  it  is  shorter.     L.  compressus 
is  entirely  different  in  the  shape  of  the  scutum,  which  is  oval  and  narrow, 
keeled  only  posteriorly ;  the  caudal  flap  is  much  shorter  and  the  margin 
of  the  scutum  is  smooth. 

Thus  there  only  remain  for  comparison  L.  apus  from  central  and 
northern  Europe,  and  L.  angasi  from  South  Australia.  Of  these,  L.  apus 
(L.)  resembles  our  species  in  general  form,  length  of  abdomen  (8  exposed 
segments),  in  the  character  of  the  carina  of  the  scutum;  but  it  differs: 

1.  In  the  second  cervical  furrow,  which  is  interrupted  in  the  middle. 

2.  In  the  caudal  flap,  which  is  oval,  narrower  at  the  base,  and  about 
twice  as  long  as  wide.

3.  In  the  eyes,  which  are  said  to  be  reniform. 

L.  angasi  is  still  more  closely  allied  to  L.  hatcheri,  as  has  been  demon- 
strated above,  especially  the  caudal  flap  is  almost  identical.  This  close 
relation  of  these  two  species  is  especially  interesting  from  a  zoogeographi- 
cal  point  of  view.

Distribution.  —  Swamp  near  Amenkelt  (lower  Santa  Cruz  River), 
Patagonia  (50°  S.,  69°  W.). 

Description.  —  Allied  to  B.  coloradense  Packard  ( 1 883,  p.  338,  textfig. 
19)  from  Colorado  and  (according  to  Lilljeborg)  Fresno,  California,  and 
still  more  closely  to  B.  iheringi  Lilljeborg  (1891,  p.  424,  and  v.  Ihering, 
1895,  p.  178)  from  Rio  Grande  do  Sul,  Brazil. 

The  chief  differences  are  found  in  the  male  claspers  (second  antennae) 
(fig.  2),  which  are  very  robust  and  long  (extended,  almost  as  long  as  the 
anterior  portion  of  the  body).  Basal  joint  subcylindrical,  slightly  curved, 
with  a  distinct  tubercle  (knob)  at  the  base  on  inner  side.  Inner  margin 
in  the  distal  half  with  a  prominent  crest,  the  edge  of  which  is  finely 
dentate.  The  inner  margin  of  first  joint,  between  this  crest  and  the  basal 
knob,  is  concave.  Second  joint  almost  as  long  as  the  first,  compressed 
and  lamelliform,  and  a  little  narrower  than  the  first  joint,  with  nearly 
parallel  margins  ;  slightly  concave  on  under  side  (if  this  joint  is  stretched 
out,  the  concave  side  is  the  outer  side),  curved,  and  near  apex  strongly 
bent,  where  the  margins  form  a  distinct  lobe  on  each  side,  rendering  the 
end  of  the  second  joint  trilobate,  the  middle  lobe  being  strongly  deflected 
from  the  general  plane. 


ORTMANN:   CRUSTACEA  OF  SOUTHERN  PATAGONIA.  645 

In  the  female  the  claspers  are  very  short,  stout,  straight,  slightly  taper- 
ing and  suddenly  truncated  at  the  end,  with  the  outer  margin  produced 
into  a  short  spine.  Ovisac  very  long,  two  thirds  as  long  as  the  abdomen, 
reaching  to  the  penultimate  abdominal  segment ;  its  end  pointed. 

Caudal  appendages,  in  both  sexes,  rather  long,  about  twice  as  long  as 
the  terminal  segment. 

Length  of  body  (in  male  and  female),  about  15  mm. 

Remarks.  —  I  had  drawn  up  the  above  description,  before  I  became 
acquainted  with  vop  Daday's  paper.  After  having  seen  the  latter,  I  was 
at  once  convinced  that  our  specimens  belong  to  this  species,  although  my 
description  does  not  agree  completely  with  that  given  by  von  Daday, 
But  this  seems  to  be  due  to  a  different  interpretation  we  have  given  to 
the  microscopic  image,  and  after  a  renewed  examination,  I  do  not  see 
any  reason  why  I  should  alter  my  original  account. 

The  description  of  B.  ikermgt,  given  by  Lilljeborg,  applies  in  some  de- 
gree, as  far  as  it  goes,  to  our  species.  Lilljeborg  says  that  there  are  a  few 
small  spinules  on  the  inner  side  of  the  first  joint  of  the  male  claspers,  and 
that  the  second  joint  has,  at  the  apex,  a  tubercle  on  the  posterior  margin, 
and  a  tuberosity  on  the  anterior  side.  While  this  structure  appears  to  be 
similar  to  that  found  in  our  species,  the  spinules  of  the  first  joint  are,  in 
the  latter,  represented  rather  by  a  denticulate  crest,  and,  further,  Lilljeborg 
does  not  mention  the  peculiar  laminate  form  of  the  second  joint,  which,  in 
our  species,  has  no  tubercles  or  tuberosities  at  the  apex,  but  rather  lamel- 
liform  lobes.  (The  peculiar  shape  of  this  joint  is,  in  my  opinion,  not  quite 
correctly  understood  by  von  Daday.)  Finally  B.  iheringi  is  smaller  than 
our  species,  only  8  mm.  the  9,  1 1  mm.  the  $ ,  while  B.  granulosa  attains, 
according  to  our  material,  15  mm.,  and  according  to  von  Daday  15-18 
mm.  Thus  B.  granulosa  seems  to  be  different  from  B.  iheringi,  although 
closely  allied  to  it.

2  Sphcsroma  lanceolatum  of  Dana,  Cunningham,  Miers,  belongs  to  this  species.  Studer  (1884), 
who  had  specimens  from  Kerguelen  and  New  Zealand,  as  well  as  from  the  Straits  of  Magellan, 
keeps  both  sets  separate,  and  calls  the  first  by  the  name  of  S.  gigas,  the  second  by  that  of  5. 
lanceolatum,  but  he  does  not  give  any  characters,  so  that  it  is  impossible  to  decide,  whether  his 
5.  lanceolatum  is  really  that  of  White. 


ORTMANN:   CRUSTACEA  OF  SOUTHERN  PATAGONIA.  647 

Locality. —  Punta  Arenas,  several  hundred  specimens,  young  and  adult. 

Distribution. —  Falkland  Islands ;  Tierra  del  Fuego ;  Straits  of  Magellan. 
Shallow  water.  This  species  also  has  been  reported  from  New  Zealand, 
Auckland  Islands,  Australia,  and  Kerguelen  Islands. 

Remarks. —  Our  largest  individuals  attain  the  length  of  about  25  mm., 
by  a  width  of  about  15  mm.  They  all  agree  in  the  essential  characters, 
and  represent  the  typical  form  of  E.  gigas,  as  described  and  figured  by 
Stebbing,  with  the  only  exception  that  in  Stebbing's  figure  of  the  whole 
animal  (pi.  39)  the  outer  ramus  of  the  uropods  is  broader  than  in  our 
individuals,  in  which  it  is  distinctly  narrower,  the  end  being  sometimes 
subacute,  sometimes  rounded.  In  this  respect,  our  specimens  correspond 
better  with  the  figure  given  by  Dollfus,  yet  Dollfus  says  that  there  are 
variations  in  this  respect.

Localities. —  Mouth  of  Santa  Cruz  River,  i  smooth,  14  sculptured  speci- 
mens ;  San  Julian,  3  smooth,  2  sculptured  specimens. 

Distribution. —  Falkland  Islands  and  Tierra  del  Fuego  (region  of  Cape 
Horn).  Shallow  water  to  95  m. 

Description.  —  This  species  differs  from  the  foregoing  in  the  following 
particulars  : 

1.  In  the  smaller  size.     While  E.  gigas  attains  25  mm.,  Dollfus  gives, 
for  this  species,  only  12  mm.,  and  our  largest  is  14  mm.     White  gives 
%    to  i  inch  (18-25  mm.),  but  these  measurements  apparently  include 
E.  gigas. 

2.  In  the  epimera  of  the  peraeon-segments,  which  are  abruptly  bent 
down,  so  as  to  form  a  sharp  angle  with  the  middle  of  the  back,  which  is 
sometimes  cariniform.     This  character  is  very  important,  and  never  found 
in  E.  gigas. 

3.  In  the  sculpture  of  the  posterior  peraeon-segments,  of  the  pleon  and 
telson.     This  sculpture  varies  considerably,  but  in  E.  gigas  there  is  no 
sculpture  at  all. 


648  PATAGONIAN    EXPEDITIONS:     ZOOLOGY. 

4.  In  the  more  narrowed  apex  of  the  telson,  which  may  be  called  sub- 
acute,  and  which  is  a  little  more  produced  than  in  E.  gigas. 

Remarks. — As  regards  the  third  character,  given  above,  the  original 
description  of  White  says  that  the  last  joint  of  the  abdomen  has,  near  the 
base,  a  slight  elevation,  grooved  in  the  middle.  Stebbing  says  that  there 
is,  on  the  telson  of  the  specimen  he  is  inclined  to  refer  to  this  form,  a  longi- 
tudinal groove  between  two  elevations,  and  then  a  carina  running  to  the 
end.  I  have  asked  for  further  information  from  Mr.  Stebbing,  and,  in  a 
letter,  he  kindly  has  furnished  the  additional  character,  that  the  last  three 
segments  of  the  perseon  have,  along  the  hind  margin  of  each,  four  small 
tubercles. 

Among  our  material,  those  specimens  called  the  "smooth  form,"  show 
exactly  the  characters  given  by  White  and  Stebbing :  a  low  elevation  on 
the  telson,  divided  by  a  groove,  and  an  indistinct  median  keel  running 
backward,  so  that  there  is  no  doubt  that  they  belong  to  White's  S. 
lanceolatum.  I  do  not  see,  however,  the  four  tubercles  observed  by 
Stebbing  on  the  peraeon-segments.  The  pleon  and  telson  of  these 
individuals  possess  fine  granulations. 

As  regards  S.  calcarea  of  Dollfus,  the  chief  characters  are,  beside  the 
double  keel  in  the  anterior  part  of  the  telson,  and  the  single  median  keel 
in  the  posterior,  the  distinct  and  prominent  granulations  on  the  posterior 
part  of  the  body,  chiefly  on  the  telson.  This  character  is  strongly  pro- 
nounced, among  our  specimens,  in  those  that  have  been  called  above  the 
"sculptured  form."  These  granulations  are  somewhat  irregular,  and 
assume  sometimes  an  almost  vermiculate  appearance.  This  form  also 
shows  the  four  little  tubercles  on  the  hind  margins  of  the  three  posterior 
peraeon-segments,  observed  by  Stebbing.  There  is  much  variety  in  the 
degree  of  development  of  the  granulations. 

The  fact  that  Dollfus  mentions  a  smooth  form,  and  that  these  two 
forms,  the  smooth  and  the  sculptured,  also  have  been  found  associated  by 
Mr.  Hatcher  at  Santa  Cruz  and  San  Julian,  while  the  typical  E.  gigas  is 
found  not  at  all  at  these  localities ;  and  further,  the  fact  that  among  the 
large  number  of  E.  gigas  collected  by  Hatcher  at  Punta  Arenas  not  a 
single  individual  of  these  forms  has  been  discovered,  is  much  in  favor  of 
the  view  that  they  really  belong  together,  that  is  to  say,  to  White's  S. 
lanceolatum.  All  our  specimens  from  Santa  Cruz  and  San  Julian  differ 
in  the  same  four  characters,  mentioned  above,  from  S.  gigas,  and  further, 


ORTMANN:  CRUSTACEA  OF  SOUTHERN  PATAGONIA.      649 

Mr.  Stebbing  informs  me  that  Dollfus'  5.  calcarea  might  very  well  be  a 
form  of  that,  which  he  is  inclined  to  take  for  White's  S.  lanceolatum. 

The  question  remains,  whether  Dollfus  was  justified  in  calling  his 
species  by  the  name  of  5".  calcarea  Dana.  Dana's  species  came  from 
Tierra  del  Fuego,  but  his  description  and  figure  (1852,  p.  776,  pi.  52,  f.  2) 
do  not  give  any  characters  that  warrant  this  identification,  and  considering 
the  adverse  conditions  by  which  Dana  was  hampered  in  the  preparation 
of  his  figures  and  diagnoses  (see  Stebbing,  1900,  p.  528),  we  had  better 
disregard  S.  calcarea  Dana  altogether. 

As  regards  the  outer  ramus  of  the  uropods,  which  is  given  by  White 
as  an  additional  distinctive  character  of  S.  lanceolatum,  I  cannot  say  that 
it  is  very  distinct  from  that  of  E.  gigas.  It  is  lanceolate,  mostly  rounded 
at  the  apex,  but  sometimes  subacute,  and  offers  about  the  same  shape  and 
variations  as  in  E.  gigas. 

This  species  also  belongs  to  the  genus  Exosphaeroma  as  defined  by 
Stebbing.

Localities.  —  This  species  seems  to  be  very  abundant  in  southern  Pata- 
gonia. Hatcher  has  collected  it  at  about  30-35  localities  in  the  region 
of  the  Rio  Chico  (47-50°  S.),  from  near  the  coast  to  the  Cordilleras 
(highest  altitudes  :  1,750  and  2,000  feet).  It  is  found  in  springs,  small 
streams  and  pools  of  fresh  water,  sometimes  slightly  alkaline  (Arroyo  Gio). 


ORTMANN:   CRUSTACEA  OF  SOUTHERN  PATAGONIA.  651 

Distribution.  —  Although  a  new  species,  some  previous  references  might 
possibly  belong  to  it.  As  we  shall  see  below,  a  locality  from  which  Faxon 
mentions  H.  dentata  inermis,  may  belong  to  this  species,  namely  :  Puerto 
Bueno,  Smyth  Channel,  Straits  of  Magellan.  The  same  form,  H.  inermis 
has  been  mentioned  by  Wierzejski  (1892,  p.  187)  from  a  stream  that  issues 
from  a  lagune  near  Mendoza  (northern  Argentina),  the  water  of  which  has 
an  odor  of  sulphur.  However,  what  this  form  really  is,  remains  to  be  seen. 

Cunningham  (1871,  p.  498,  pi.  59,  f.  14)  mentions  Allorchestes  pata- 
gonicus  from  a  freshwater  stream  near  Punta  Arenas.  He  does  not  give 
any  description,  since  his  single  specimen  was  considerably  injured,  and 
the  figure  is  quite  poor,  and,  no  doubt,  even  incorrect.  It  is  possible  that 
our  species  was  intended,  but  we  have  no  means  of  deciding  this,  and  Al- 
lorchestes patagonicits  must  remain  a  "nomen  nudum." 

Description.  —  Body  rather  robust,  general  form  agreeing  with  that  of//. 
dentata  inermis  Sm.  Eyes  small,  black,  rounded,  about  twice  their  diam- 
eter distant  from  one  another. 

Antennulae  longer  than  the  stalk  of  the  antennae,  a  little  more  than 
half  as  long  as  the  whole  of  the  antennae.  First  and  second  joint  of 
peduncle  of  the  same  length,  third  a  little  shorter.  Flagellum  with  10-12 
joints  in  the  tf,  and  with  8-10  joints  in  the  9. 

Antennas  about  one  third  as  long  as  the  body,  or  even  shorter.  The 
first  joint  of  the  peduncle  short,  the  second  a  little  longer,  the  third  dis- 
tinctly longer  than  the  second.  Flagellum  with  12-17  joints  in  the  tf, 
and  with  9-  1  4  joints  in  the  9.1 

Maxillipeds  (fig.  3,  a)  of  the  usual  form,  but  all  the  joints  are  more 
slender  than  in  H.  dentata  inermis. 

First  gnathopod  of  the  cT  (fig-  3,  &}  '•  Meropodite  with  a  blunt  promi- 
nence on  the  inferior  margin,  which  is  beset  with  a  number  of  setae.  Car- 
popodite  about  twice  as  long  as  meropodite  (measured  from  the  middle  of 
the  articulation  with  meropodite  to  the  middle  of  articulation  with  propo- 
dite),  upper  margin  with  a  sharp  spine  near  the  distal  end,  which  has  a 
group  of  setae  ;  lower  margin  with  a  very  prominent,  lobiform,  rounded 
projection,  the  margin  of  which  is  fringed  with  stiff  setae.  Propodite 
almost  triangular,  almost  as  wide  as  long,  and  about  as  long  as  carpopo- 


number  of  joints  of  the  flagella  of  both  antennulae  and  antennae  varies  with  age:  it  is 
less  in  young  individuals,  greater  in  adults.  Often  the  number  differs  on  either  side;  this  differ- 
ence, however,  is  always  slight,  only  amounting  to  one  or  two  joints.

dite;  palmar  margin  oblique,  nearly  straight,  with  several  rows  of  setae,  which 
become  spine-like  at  the  outer  end  ;  just  below  this  end  there  is  a  group  of 
more  numerous  setae.  There  is  no  excavation  to  receive  the  tip  of  the 
dactylus.  Outer  surface  of  palm  with  an  oblique  row  of  setae.  Dactyr 
lopodite  slender,  slightly  curved. 

First  gnathopod  of  9  (fig.  3,  c]  similar  to  that  of  the  J1,  but  propodite  less 
distinctly  triangular,  and  accordingly,  less  wide  in  proportion  to  length. 

Second  gnathopod  of  J1  (fig.  3,  d}:  meropodite  with  a  triangular,  pointed 
prominence  on  the  lower  margin.  Carpopodite  about  as  long  as  mero- 
podite, with  a  narrow,  pointed  prolongation  of  the  lower  margin,  which 
is  longer  than  the  width  of  the  rest  of  the  carpopodite.  Palm  (measured 
along  the  upper  border)  about  4  times  as  long  as  carpopodite,  triangular, 
swollen,  in  general  form  very  similar  to  that  of  H.  dentata  inermis. 
Palmar  margin  oblique,  very  slightly  sinuous,  with  a  series  of  small  spines ; 
the  lower  (outer)  end  with  a  depression  to  receive  the  tip  of  the  dactylo- 
podite,  and  around  this  depression  with  2-3  stronger  spines.  Dactylo- 
podite  slender  and  curved. 

Second  gnathopod  of  9  (fig.  3,  e)  similar  to  the  first  gnathopods  of 
J1  and  9,  but  meropodite  with  the  prominence  of  the  under  margin  more 
pronounced  (but  not  triangular  and  pointed,  as  in  the  second  gnathopod 
of  the  oT)  ;  process  of  lower  margin  of  carpopodite  a  little  longer  than 
that  of  the  first  gnathopod,  and  palm  still  more  elongated,  distinctly 
longer  than  the  carpopodite,  and  less  triangular  than  that  of  the  first 
gnathopod  of  the  9-  (This  is  very  dissimilar  to  that  of  H.  dentata 
inermis. .) 

Peraeopods  :  First  (fig.  $,/},  second  and  third  of  about  the  same  length, 
fourth  longer  than  third,  fifth  (fig.  3,  g]  about  as  long  as  fourth.  The 
last  (fifth)  extends  backward  a  little  beyond  the  tip  of  the  first  uropod. 
Basipodite  of  third  to  fifth  enlarged,  oval,  that  of  fifth  pair  larger  than 
those  of  the  third  and  fourth.  Hind  edge  of  third,  fourth  and  fifth  ser- 
rated, most  distinctly  so  in  the  fifth.  Accessory  branchiae  on  the  first  to 
the  fifth  peraeopods.  No  ordinary  branchiae  on  fifth. 

Uropods  (fig.  3,  h]  :  First  and  second  with  spines  on  both  rami.  Third 
uropods :  ramus  about  as  long  as  the  peduncle,  only  slightly  extending 
beyond  telson. 

Telson  (fig.  3,  h},  almost  semicircular,  or,  more  correctly,  half-elliptic, 
with  a  pair  of  fine  setae  on  the  rounded  hind  margin.

Brazil). 

9.  Hyalella  meinerti  Stebb.,  from  "  Laguna  di  Espino."2 

All  these  forms  belong  to  the  genus  Hyalella,  founded  by  S.  J.  Smith 
(1874),  and  more  sharply  defined  by  Stebbing  (1899,  pp.  397-398)  in  his 
key  to  the  genera  of  the  family  Orchestiidce. 

H.  dentata  from  the  United  States  differs  from  our  species  (and  all  the 

*As  has  been  surmised  by  Smith  and  Faxon,  this  species  is  very  likely  identical  with  Allorchestes 
knickerbockeri  Bate  (1862,  p.  36,  pi.  6,  f.  i)  from  New  York,  and  possibly  with  Amphithoe  aztecus 
Saussure  (1858)  from  Vera  Cruz,  Mexico.  If  the  latter  should  prove  to  be  true,  the  specific 
name  of  aztecus  should  be  used. 

*  I  have  tried  to  locate  "Laguna  di  Espino,"  but  have  been  unable  to  do  so.  Places  called  by 
the  name  of  "Espino"  are  found  in  Honduras  and  Venezuela  (prov.  Guarico),  but  no  "Laguna  di 
Espino"  is  known  to  me.

rest)  in  the  spiniform  prolongation  of  the  segments  of  the  pleon.  This 
character,  however,  seems  to  be  of  minor  importance,  since  there  are 
intergradations  in  this  respect  between  the  typical  H.  dentata  and  H. 
inermis  in  the  United  States  (see  Smith,  1874,  Fish  Comm.,  p.  647  ; 
specimens  from  Florida).  Faxon  regards  H.  inermis  only  as  a  variety 
of  H.  dentata. 

In  all  other  characters,  H.  dentata  as  well  as  H.  inermis  are  closely 
allied  to  our  species,  especially  the  following  characters  agree  : 

1.  General  shape  of  body  and  eyes. 

2.  Length  of  antennulae  and  antennae.     In  H.  dentata  and  H.  inermis 
these  are  considerably  shorter  than  half  of  the  body. 

3.  Shape  of  the  second  gnathopod  of  the  J*.     Especially  the  propodite 
is  directly  identical,  as  will  be  seen  by  comparing  our  figure  (3^)  with  the 
figure  of  this  joint  of//,  dentata  (cT  ad.)  given  by  Smith  (1874,  Geol.  Surv., 

pl.  i,  f-  3). 

4.  Relative  length  of  the  peraeopoda. 

5.  Shape  of  uropods  and  telson. 

The  chief  differences  are  the  following : 

1.  The  number  of  joints  of  both  antennulae  and  antennae  is  greater  in 
our  species.     Although  these  parts  are  about  as  long  as  those  of  H.  den- 
tata and  inermis,  the  number  of  joints  is  slightly  greater  in  H.patagonica 
(in  dentata  and  inermis,  7-9  in  the  antennulae,  8-12  in  the  antennas;  in 
H.patagonica^  8-12  in  the  antennulae,  9-17  in  the  antennas).     The  joints 
of  the  peduncles  are  a  little  different  in  length ;  while  of  those  of  the  an- 
tennulae, in  H.  dentata  and  inermis,  the  two  distal  ones  are  about  alike, 
the  last  joint,  in  our  species,  is  a  little  shorter  than  the  second.     In  the 
antennae,  the  second  and  third  joints  are  alike  in  H.  dentata  and  inermis, 
while,  in  H.  fiatagonica,  the  third  is  distinctly  longer  than  the  second. 
These  differences,  however,  seem  to  be  of  minor  importance. 

2.  In  the  first  gnathopod  of  the  $  as  well  as  the  $,  the  propodite  is,  in 
H.  patagonica,  distinctly  broader  and  more  triangular ;  the  propodite  has  a 
distinct  lobiform  prominence,  which  is  much  more  developed  than  in  H. 
dentata  and  inermis,  and,  consequently,  the  carpopodite  appears  shorter 
and  broader  in  our  species. 

3.  The  same  is  true  of  the  second  gnathopod  of  the  9 '  the  carpopodite 
and  propodite  are  shorter  and  comparatively  broader  in  our  species,  and 
the  process  of  the  carpopodite  is  more  pronounced.     The  propodite  in  H. 
dentata  and  inermis  is  much  longer  than  in  our  species. 


ORTMANN:    CRUSTACEA  OF  SOUTHERN  PATAGONIA.  655 

4.  In  our  species,  the  meropodite  of  the  second  gnathopod  of  the  '$ 
has  a  triangular,  pointed  prominence  on  the  lower  margin,  while  in  H. 
dentata  and  inermis  this  process  is  blunt  and  obtuse. 

5.  Size  of  our  species  much  larger,  up  to  16  mm.,  while  H.  dentata  and 
inermis  measure  not  more  than  6  mm. 

Thus  we  see  that  H.  patagonica  differs  from  H.  dentata,  and  especially 
from  H.  inermis,  in  some  slight  and  unimportant  features  of  the  antennulae 
and  antennae,  and  in  some  very  marked  characters  of  the  first  and  second 
gnathopods  of  the  $  and  9,  and  in  size.  Nevertheless,  these  three  forms 
seem  to  be  very  closely  allied  in  the  general  shape  of  the  body,  length  of 
antennulae  and  antennae,  and  the  general  shape  of  the  chelae  of  the  second 
gnathopods  of  the  J1. 

It  remains  doubtful,  whether  Faxon's  H.  dentata  var.  inermis  from 
South  America  is  really  identical  with  the  form  of  the  United  States. 
Faxon  says  that  his  Lake  Titicaca  specimens  exhibit  some  differences  in 
the  shape  of  the  propodite  of  the  second  gnathopods  of  the  cT,  but  his 
figure  does  not  reveal  them  in  a  sufficient  degree.  Considering  the  fact 
that  we  possess  several  hundred  individuals  of  our  species,  and  that  they 
all  show  a  great  uniformity  in  their  characters,  and  that  the  differences 
mentioned  above  are  constant  among  them,  it  is  possible  that  also  the 
Titicaca  form  —  of  which  Faxon  had  only  6  specimens  —  might  be  a  good 
species.  As  to  the  specimens  from  Peru  and  the  Straits  of  Magellan, 
Faxon  does  not  give  any  details  of  their  characters,  but  I  suspect  very 
strongly  that  those  from  the  latter  locality  really  belong  to  our  species. 

H.  dentata  var.  gracilirostris  (Fax.)  from  Brazil  differs  at  once  from  all 
others,  discussed  so  far,  in  the  much  longer  antennae,  which  are  half  as 
long  as  the  body.  There  may  be  other  characters  that  differ,  to  which 
Faxon  does  not  refer.  He  had  only  one  female. 

H.  longistilus  (Fax.)  from  Brazil  differs  at  once  in  the  third  uropods, 
which  are  much  longer,  and  in  the  longer  antennulae  and  antennae.  Car- 
popodite  of  second  gnathopod  of  J1  more  oval,  and  less  distinctly  triangular. 

H.  jelskii  (Wrz.)  from  Peru  differs:1 

i.  Antennulae  and  antennae  much  longer,  and  the  antennae  of  the  <$ 

lWrzesniowsky  does  not  give  any  figures  of  his  species,  and  consequently  we  cannot  form, 
in  some  points,  a  good  idea  as  to  their  characters.  Nevertheless  his  descriptions  are  generally 
clear,  and  do  mention  characters  that  show  conclusively  that  his  species  are  different  from  H. 
patagonica. 


656  PATAGONIAN   EXPEDITIONS:     ZOOLOGY. 

are  two  thirds  of  the  length  of  the  body.     Number  of  joints  about  the 
same  as  in  our  species  (antennae  of  <?,  18  joints). 

2.  Shape  of  first  gnathopod  different,  the  carpopodite  large,  distinctly 
longer  (i#  times  as  long  as  propodite). 

3.  In  the  second  gnathopods  of  the  <?,  carpopodite  about  one  third  of 
the  propodite  (expression  ambiguous:   "  dreimal  kuerzer"),  and  propo- 
dite apparently  shorter  than  in  our  species.     For  the  rest,  the  propodite 
seems  to  possess  a  similar  shape,  although  the  spinules  of  the  palmar 
margin  seem  to  be  different. 

4.  The  propodite  of  the  second  gnathopod  of  the  9  seems  to  be  quite 
different,  being  2.yz   times  as  long  as  broad. 

5.  No  accessory  branchiae  on  the  fifth  peraeopods. 

6.  Size  smaller  (5  mm.). 

Thus  it  seems  that  this  species  is  much  more  different  from  H.  pata- 
gonica  than  H.  inermis,  especially  in  the  shape  of  the  antennulae,  antennae 
and  gnathopods. 

H.  hibomirskii  (Wrz.)  from  Peru  differs  from  our  species  : 

1.  Head  shorter,  and  eyes  oval  (not  round). 

2.  Antennulae  and  antennae  longer  (antennae  of  $  over  one  half  of  the 
body).     Number  of  joints  slightly  greater. 

3.  Second  gnathopods  of  <$  apparently  similar  to  our  species,  but  palmar 
margin  cut  into  two  lobes,  and  meropodite  \yz   times  as  long  as  carpo- 
podite.    In  the   9,  the  propodite  is   longer  than  in  our  species,  almost 
twice  as  long  as  wide. 

4.  Size  smaller  (6  mm.). 

Here  the  first  gnathopods  are  apparently  more  like  //.  patagonica  (car- 
popodite hardly  longer  than  propodite).  This  species  resembles  more 
H.  inermis  in  the  first  and  second  gnathopods,  but  head,  eyes,  antennulae 
and  antennae  are  different. 

H.  dyboivskii  (Wrz.)  from  Peru  differs  from  our  species  : 

1.  Eyes  oval,  dilated  below. 

2.  Antennae    longer  (half  as   long  as   body).     Number   of  joints   of 
antennulae   and    antennae    near  that  of  our  species   (antnl.   10-13,  ant- 

H-I5). 

3.  Carpopodite  and  meropodite  of  second  gnathopod  about  one  third 

as  long  as  propodite.1     For  the  rest  the  first  and  second  gnathopods  seem 

l"Zweimal  kuerzer."    This  expression  is  very  ambiguous,  in  a  double  sense. 


ORTMANN:    CRUSTACEA  OF  SOUTHERN  PATAGONIA.  657 

to  resemble  those  of  H.  patagonica,  although  the  description  is  very  short 
and  incomplete. 

This  species  seems  to  be  the  most  closely  allied  form  among  thoSe 
described  by  Wrzesniowsky ;  it  differs,  however,  distinctly  in  the  shape 
of  the  eyes  and  the  length  of  antennulae  and  antennae. 

H.  warmingi  Stebb.,  from  Lagoa  Santa,  Brazil. 

This  species  differs  at  once  and  strikingly  in  the  shape  of  the  propodite 
of  the  second  gnathopod  of  the  d\  which  is  more  oval,  and  in  the  shape 
of  the  first  gnathopod  and  the  second  gnathopod  of  the  9.  Also  the 
antennae  are  much  longer,  so  that  we  do  not  need  to  compare  it  further. 

H.  meinerti  Stebb.,  from  "  Laguna  di  Espino." 

This  is  entirely  different  in  the  third  uropods,  which  resemble  those  of 
H.  longistihts  (Fax.),  and  further,  the  shape  of  the  first  and  second 
gnathopods  and  the  length  of  the  antennae  are  quite  unlike  our  species. 

Thus  we  see  that  the  species  most  closely  allied  to  H.  patagonica  is  H. 
inermis  of  the  United  States.  According  to  Faxon,  this  species  (or  variety) 
is  also  found  in  Peru,  near  Lake  Titicaca,  and  in  the  region  of  the  Straits 
of  Magellan.  Yet  Faxon  regards  differences  in  the  shape  of  the  first  and 
second  gnathopods  not  as  specific  characters,  and  thus  it  is  quite  possible 
that  his  South  American  specimens  represent  good  species,  different  from 
H.  inermis.  I  have  said  above  that  the  differences  of  H.  patagonica  from 
H.  inermis,  although  seemingly  unimportant,  are  constant  among  the 
large  number  of  our  specimens,  and  consequently,  I  am  forced  to  regard 
this  Patagonian  form  as  a  new  and  good  species. 

The  fact  that  the  type  of  fresh-water  amphipods,  represented  in  the 
United  States  by  Hyalella  dentata  and  inermis  extends,  apparently, 
throughout  America,  over  Central  and  South  America  to  the  Straits  of 
Magellan,  while  this  genus  is  found  nowhere  else,  is  very  interesting  from 
a  zoogeographical  point  of  view.

Distribution. — Falkland  Islands ;  Tierra  del  Fuego  ;  Straits  of  Magellan. 
On  the  eastern  Patagonian  coast  this  species  has  been  found  as  far  north 
as  Bahia  Blanca  (Prov.  of  Buenos  Aires),  38°  42'  S.  (Berg,  1900),  while 
on  the  western  coast  it  does  not  seem  to  go  beyond  Trinidad  Channel 
(50°  S.). 

Remarks.  —  According  to  Stebbing,  the  specific  name  of  P.  granulosa 
has  to  supersede  that  of  P.  verrucosa,  having  been  published  (on  Jacqui- 
not's  plate)  not  later  than  in  1847,  while  L.  verntcosa  of  Dana  was  pub- 
lished in  1852. 

The  two  young  individuals  from  Cape  Fairweather  correspond  closely 
to  L.  verrucosa  of  Dana  (1852,  p.  428,  pi.  26,  f.  16).  Both  have  the 
length  of  the  carapace,  27  mm.  The  specimens  from  Punta  Arenas  are 
all  larger,  and  most  of  them  seem  to  be  adult ;  the  smallest,  a  soft  shell 
female,  is  61  mm.  long  (carapace  only),  and  this  one  is  intermediate  in 
sculpture  between  the  young  and  adult  specimens  ;  the  tubercles  of  the 
surface  are  more  crowded  than  in  the  latter,  but  a  little  more  distant  from 
each  other  than  in  the  former.  The  same  is  true  of  the  granulations  of 
these  tubercles,  they  being  less  developed  than  in  P.  verrucosa,  but  more 
strongly  than  in  the  adult  individuals.  Length  of  adult  males  :  92,  101, 
107  mm.;  of  an  adult  female:  72  mm. 

This  leaves  no  doubt  as  to  the  identity  of  P.  granulosa  and  verrucosa, 
the  former  being  only  the  young  stage  of  the  latter,  as  already  Bouvier 
(1896)  maintained.

Remarks.  —  The  specific  differences  of  this  species  have  been  set  forth 
best  by  A.  Milne-Edwards,  and  I  have  been  able  to  verify  them  in  our 
material. 

Henderson's  M.  subrugosa  is  the  true  M.  subrugosa,  although  he  also 
gives,  among  the  synonyms,  Grimotliea  gregaria  (with  a  ?) :  he  states 
expressly  (p.  125)  that  no  specimens  representing  the  latter  form  were 
taken  by  the  Challenger,  and,  further,  he  doubts  the  correctness  of  the 
identification  of  these  two  species.

It  is  doubtful  whether  this  species  is  also  found  in  New  Zealand,  since 
it  has  been  confounded  by  some  authors  with  M.  subrugosa.  A  form 
allied  to  this  is  mentioned  by  Filhol  (1885,  p.  426)  from  Cook  Strait, 
New  Zealand  :  he  distinguishes  it  well  from  M.  stibrugosa,  but  says  that 
it  is  also  not  quite  identical  with  "  Grimothea  gregaria"  and  proposes  the 
name  of  Grimothea  novce-zelandice  for  it.  See  also  Benedict,  1.  c.

as  Milne-Edwards'  adult  male).  It  agrees  well  with  the  description  in 
every  respect,  but  the  spinules  of  the  upper  part  of  the  carapace  are  less 
distinct,  although  present.  The  latter  character  seems  to  be  not  very 
important,  since  a  variety  of  M.  stibrugosa  (var.  australiensis]  also  pos- 
sesses a  larger  number  of  spinules  on  the  carapace  than  the  typical 
subrugosa.

species  :  H.  ovatus  Stps.  (see  Stebbing,  1.  c.). 

Remarks. — The  young  J1  from  San  Julian,  and  the  three  young  $  from 
Punta  Arenas,  of  the  lengths:  2.5-3-3.5-4  mm.,  agree  completely  with 
Dana's  H.  pitbescens,  which  is  said  to  be  one  tenth  of  an  inch  long  ( =  2-3 
mm.) :  the  form  of  the  carapace  is  more  rounded  (less  transverse  than  in  H. 
planatus],  the  walking  legs  (and  sometimes  the  carapace)  are  slightly  pubes- 
cent, and  the  sides  of  the  male  abdomen  are  parallel,  with  the  exception  of 
the  last  joint.  A  young  J1 ,  6  mm.  long  has  the  typical  form  of  the  male 
abdomen  of  H.  planatus,  but  the  form  of  the  carapace  is  less  transverse. 
The  pubescence  is  not  present.  Larger  males  (from  10  mm.  upward) 
acquire  by  degrees  the  greatly  swollen  chelipeds.  Our  largest  male  has 
the  following  measurements:  Length  13  mm.,  width  16  mm.

A.  Milne-Edwards  describes  the  rostrum  of  this  species  as  bifid  with 
two  lateral  teeth  :  in  most  of  our  individuals,  however,  it  is  three-spined, 
the  median  spine  being  entire  ;  only  in  rare  cases  there  is  a  slight  emar- 
gination  or  notch  at  its  distal  extremity.

ORTMANN:   CRUSTACEA  OF  SOUTHERN  PATAGONIA.  663 

We  see  at  once  that,  while  the  prevailing  features  of  the  southern 
Patagonian  marine  fauna  are  made  up  chiefly  by  peculiar  species,  another 
large  part  of  the  fauna  shows  unmistakable  affinities  to  other  Antarctic 
countries.  Looking  more  closely  upon  the  peculiar  types  (group  4),  we 
are  able  to  state  the  following  particulars  with  regard  to  their  relationship 
to  other  parts  of  the  world. 

The  genera  Elminius,  Edotia,  and  Eurypodius  do  not  find  any  closer 
relations  elsewhere.  Exosphceroma  and  Serolis  are  distinctly  Antarctic 
types,  while  the  affinities  of  Rocinela  and  Munida  are  more  or  less  cosmopoli- 
tan. There  remain  only  the  two  Lithodidce  and  Hypopeltarium.  The  Litho- 
didce  apparently  are  to  be  classed  with  those  forms  which  possess  a  kind 
of  bipolar  distribution,  but  where  the  two  polar  areas  are  connected  along 
the  western  coast  of  America.  This  has  been  called  by  the  present 
writer  "  meridional  distribution,"  *  and  such  cases  are  not  considered  to 
belong  to  "  bipolarity  "  in  the  original  sense.  Hypopeltarium,  which  is 
represented  in  European  waters  by  Atelecyclus,  might  be  taken  for  a  case  of 
bipolarity,  if  it  were  not  for  the  fact  that  a  species  of  this  genus  lately  has 
been  discovered  in  the  West  Indian  region.2  This  renders  it  impossible 
to  regard  this  case  (of  Hypopeltaritvn  and  Atelecyclus]  as  one  of  bipolarity. 

Examining  the  Antarctic  types  (group  3),  we  find  that  none  of  them 
can  be  regarded  as  a  representative  of  any  characteristic  Arctic  form, 
although  among  the  five  isopods  the  generic  affinities  need  further  investi- 
gation. This  much  is  known,  that  all  five  of  them  are  hardly  represented 
in  any  part  outside  of  the  Antarctic  regions.  The  same  is  true  of  Halicar- 
cinus,  while  Munida,  as  has  been  stated  above,  is  cosmopolitan. 

Thus,  among  the  forms  discussed  here,  the  bulk  is  to  be  regarded  as 
peculiar  to  this  region,  representing  a  local  Magellanian  fauna.  A  large 
part  of  this  fauna  exhibits  characteristic  Antarctic  affinities,  pointing  to  a 
former  closer  connection  of  the  different  parts  (South  America,  New  Zea- 
land, Australia,  Kerguelen,  etc.).  The  remaining  small  number  represent 
either  immigrants  from  the  north,  along  the  western  coast  of  America,  or 
more  or  less  cosmopolitan  types. 

The  Magellanian  fauna,  according  to  this  material  —  and  this  is  no 
doubt  a  fair  representation  of  the  more  abundant  forms  of  it — is  descended

from  a  general  Antarctic  fauna,  which  has  developed  some  peculiar  local 
types  ;  a  few  elements  of  it  (Elminius,  Edotia,  Eurypodius]  seem  to  be 
altogether  peculiar  to  these  parts,  while  a  few  others  belong  to  different 
sources  ;  some  immigrated  from  the  north,  and  others  are  cosmopolitan 
forms,  the  original  home  of  which  cannot  be  traced.  No  indications  of 
bipolarity  are  found,  that  is  to  say,  in  no  case  are  the  affinities  of  any  of 
these  Antarctic  forms  to  Arctic  forms  closer  than  to  any  other  region  of 
the  earth. 

This  points  distinctly  to  the  former  existence  of  an  Antarctic  fauna 
peculiar  to  the  shores  of  the  supposed  old  Antarctic  continent,  of  which 
fauna  the  Magellanian  is  a  slightly  modified  offshoot,  blended  with  a  few 
types  of  different,  presumably  northern,  origin  and  the  view  is  supported 
that  the  Antarctic  fauna,  in  its  origin,  is  totally  different  from  the  Arctic.1 

With  regard  to  the  fresh-water  fauna  we  may  make  the  following 
remarks. 

Most  of  the  species  recorded  here  belong  to  the  class  of  those  small 
fresh-water  organisms,  for  which  exceptional  means  of  dispersal  (passive 
transport  by  wind,  water-fowl,  etc.)  are  admissible,  and  even  observed,  so 
that  a  more  or  less  cosmopolitan  distribution  is  not  astonishing.  Although 
most  of  the  species  (except  Daphnia  hastata]  are  peculiar  to  Patagonia, 
the  genera  are  universally  distributed. 

A  very  remarkable  exception  to  this  is  presented  by  the  Copepod  genus 
Pseudobceckella.  The  distribution  of  this  and  the  allied  genera  \Bceckella, 
Bczckellopsis,  Par  abac  kelld]  is  almost  exclusively  restricted  to  the  Antarc- 
tic countries  (only  in  S.  America  the  range  extends  into  Brazil).  I  give 
here  a  synopsis  of  the  known  localities,  following  Mrazek's  (1901)  classi- 
fication. 

The  genus  Boeckella  (typ.)  Mraz.  contains  three  species  from  Australia 
and  New  Zealand  (B.  triarticulata  (Thorns),  minnta  Sars,  robusta  Sars). 
To  these  we  have  possibly  to  add  :  B.  gracilipes  Dad.,  gracilis  (Dad.)  and 
Pygnuza  Dad.,  from  Patagonia  and  Chili.2 

Pseudobosckella  Mraz.  contains  the  following  species  :  brasiliensis  (Lubb.), 
Patagonia  and  Brazil  ;  poppei  Mraz.,  S.  Georgia  and  S.  Patagonia;  longi- 
cauda  (Dad.)  and  entzi  (Dad.)  both  from  Patagonia  ;  and  probably  also  : 
dubia  (Dad.)  and  silvestrii  (Dad.)  from  Patagonia.

ORTMANN:   CRUSTACEA  OF  SOUTHERN  PATAGONIA.  665 

Bceckellopsis  Mraz.  possesses  only  the  species  B.  bergi  (Rich.)  from 
Buenos  Aires  and  S.  Patagonia. 

Parabceckella  Mraz.  is  made  up  of  P.  brevicaudata  (Brad.)  from  Kergue- 
len  and  Punta  Arenas. 

This  distribution  is  so  remarkable,  including  only  S.  America,  S.  Georgia, 
Kerguelen,  Australia  and  New  Zealand,  that  this  group  of  genera,  which 
are  no  doubt  closely  related  to  one  another,  clearly  is  to  be  classed  with 
those  freshwater  and  land  animals  that  point  to  a  former  connection  of 
these  regions.1  Under  the  same  head  comes  also  Lepidurus  hatcheri  Ortm., 
of  which  we  have  demonstrated  above,  that  it  is  most  closely  allied  to 
L.  angasi  Baird  of  South  Australia.

PART  VII. 

HIRUDINEA  OF  SOUTHERN  PATAGONIA. 

BY 

J.  PERCY  MOORE, 

UNIVERSITY  OF  PENNSYLVANIA. 

N'OTHING  whatever  was  known  of  the  fresh-water  leech  fauna  of 
the  extreme  southern  end  of  South  America — of  the  entire  region 
south  of  Valdivia  on  the  Pacific  coast  and  of  Montevideo  on  the 
Atlantic  side — until  the  publication  in  1890  of  Blanchard's  account  of 
the  leeches  collected  by  Dr.  Michaelsen  on  the  Hamburg  Expedition  to 
the  Straits  of  Magellan.  In  this  paper  the  following  species  were  de- 
scribed from  Tierra  del  Fuego  and  Punta  Arenas  on  the  Straits  of  Magel- 
lan, all  having  been  collected  at  no  great  distance  from  the  coast  in  ponds, 
lakes  and  swamps :  Semiscolex  variabilis  Blanchard,  Glossiphonia  (Helob- 
delld]  chilensis  Blanchard,  Glossiphonia  (Helobdelld]  michaelseni  Blan- 
chard, and  Glossiphonia  {Helobdella)  scutifera  Blanchard. 

The  material  described  in  the  present  paper  was  collected  inland  along 
the  base  of  the  mountains  at  elevations  as  high  as  2,500  ft,  and  particularly 
from  the  numerous  springs  and  streams  which  feed  the  Rio  Chico — a 
region  from  which  no  leeches  have  hitherto  been  described.  As  regards 
the  number  of  species  the  collection  is  small,  comprising  but  six,  belong- 
ing to  only  two  families.  But  several  of  these  are  represented  by  a  great 
many  examples.  Three  of  the  four  species  recorded  by  Blanchard  from 
southern  Patagonia  are  represented ;  and  two  new  species  are  included, 
both  of  which  possess  functional  nuchal  glands,  which  in  Glossiphonia 
duplicata  are  greatly  developed.  So  far  as  appears  in  the  present  very 
incomplete  state  of  our  knowledge  of  the  fresh-water  leeches  of  this  region, 
the  most  striking  feature  of  the  fauna  is  the  predominance  of  small  glos- 
siphonids  of  the  group  designated  by  Blanchard  Helobdella.  Including 
G.  stagnalis,  which  has  been  found  as  far  south  as  Valdivia,  this  fauna 
includes  most  of  the  known  species  with  functional  nuchal  glands.

SEMISCOLEX. 
SEMISCOLEX   VARIABILIS  R.  Blanchard. 

(Plates  XLIX,  Figs.  1-9;  L,  Fig.  12.) 

Except  for  the  narrower  prostomium  and  smaller  mouth,  the  general 
aspect  is  similar  to  Hczmopis,  a  resemblance  which  is  especially  striking 
in  the  case  of  a  quite  small  individual.  The  larger  specimens  are  some- 
what flattened  posteriorly  and  rather  sharply  constricted  at  the  region  of 
the  sexual  pores,  anterior  to  which  the  body  is  narrower  and  nearly  terete. 
The  arrangement  of  the  eyes  is  shown  in  figures  i  and  7.  The  relative 
position  of  the  pigment  cups  and  the  direction  of  the  axes  of  the  eyes 
are  sufficiently  obvious.  The  pigment  cups  of  the  first  three  pairs  are 
larger  and  more  conspicuous  than  the  others.  No  sensillae  are  discernible. 

Sixteen  pairs  of  quite  conspicuous  nephridial  ducts,  appearing  as  short 
tubes  which  pass  obliquely  backward  through  the  integuments,  open  close 
to  the  posterior  margin  of  annulus  b2  of  every  somite  from  IX  to  XXIV. 
The  anus  is  a  conspicuous  opening  with  lobed  margins  as  in  Hcemopis. 

Like  Blanchard's  types  all  three  of  the  specimens  studied  by  me  have 
the  male  genital  orifice  situated  in  the  middle  of  XII  bi.  In  the  mature 
examples  it  is  a  rather  prominent  four-rayed  opening,  slightly  elevated  on 
a  broad,  low  papilla,  to  support  which  the  annulus  is  lengthened  mesially. 
In  all  three  of  Blanchard's  specimens  the  position  of  the  female  pore  dif- 
fered, ranging  from  XII  a2\b$  to  XII  b6,  being  separated  from  the  male 
pore,  therefore,  by  two  and  one  half,  three  and  one  half  and  four  annuli 
respectively.  The  intermediate  condition  was  exhibited  by  an  example 
from  Punta  Arenas,  Patagonia,  and  to  this  the  three  here  described  are 
exactly  similar.  The  female  pore  in  all  is  a  minute  opening  in  a 
depressed  area  situated  at  XII  bjlbd. 

Annulation. — The  details  of  annulation  of  the  best  preserved  mature 
example  are  exhibited  in  Plate  XLIX,  figs.  2,  3,  5-8,  and  of  the  young 
example  in  figure  4. 

Somites  I,  II,  III  and  IV  are  separated  by  no  distinct  furrows,  though 
slight  wrinkles  may  be  caused  to  appear  on  the  median  part  of  the  head 
between  the  eyes  by  bending  this  region  upward.  These  furrows,  together 
with  the  position  of  the  closely  crowded  anterior  three  pairs  of  eyes,  show 
that  the  first  three  somites  are  uniannulate.  Somite  IV  is  apparently  so 
also,  or  else  aj  is  very  obscurely  distinct,  for,  although  the  distance 


MOORE:   HIRUDINEA  OF  SOUTHERN  PATAGONIA.  671 

between  the  third  and  fourth  pairs  of  eyes  is  somewhat  greater  than  that 
separating  any  of  the  preceding  pairs,  no  distinct  intervening  annulus 
can  be  detected. 

V  is  biannulate;   the  two  annuli  —  (ai  +  a2)  and  aj  —  are  of  about 
equal  length.     The  pigment  cups  of  the  fourth  pair  of  eyes  are  at  about 
the  middle  of  the  anterior  annulus  and  placed  on  the  antero-internal  face 
of  the  sensory  cells.     The  furrow  (ai-\-a2)/aj  is  incomplete  in  the  small 
specimen  and  the  pigment  cups  of  the  eyes  reach  into  IV,  an  appearance 
due  in  part  to  contraction  and  in  part  to  the  position  of  the  head  when 
drawn. 

VI  is  also  biannulate.     On  the  dorsal  surface  a  faint  furrow  (aila2]  is 
present,  extending  about  as  far  as  the  eyes  in  the  larger  example,  but 
detectable  under  the  compound  microscope  for  the  entire  width  of  the 
head  of  the  smaller  one.     The  pigment  cups  of  the  fifth  pair  of  eyes, 
which  cover  the  anterior  face  of  the  sensory  cells,  lie  directly  beneath  this 
incipient  furrow.     The  second  annulus  (aj)  is  quite  distinct  all  around, 
making  the  somite  biannulate  ventrally  as  well  as  dorsally. 

VII  is  triannulate  ;   aj  is  distinctly  longer  than  ai  or  a2  which  are 
obviously  more  closely  associated,  the  furrow  ail 0,2  being  less  distinct 
than  a2/aj,  especially  on  the  ventral  surface. 

VIII  is  quadriannulate.     Of  the  four  annuli  ai  is  just  appreciably  longer 
than  a2  and  shows  a  faint  dorsal  furrow,  bilb2 ;  b$  and  bd  are  distinctly 
shorter  than  ai  and  a2,  and  the  furrow  b$lb6  is  a  trifle  less  deep  than 
the  others. 

There  are  sixteen  distinctly  quinqueannulate  somites,  IX  to  XXIV  in- 
clusive. In  IX  the  relative  lengths  of  the  annuli  are  represented  by  the 
formula  bi  =  b2  <  b$  =  b6  <  a2 ;  IX  bi  and  b2  =  VIII  b$  and  56.  By 
about  XI  the  formula  becomes  bi=b2  —  b^  —  b6<a2,  which  it  remains  until 
about  XXII  where  the  somites  begin  to  decrease  in  relative  and  abso- 
lute length,  owing  to  diminution  of  the  posterior  annuli.  Here 
a2  >  bi  =  b2  >  b$  —  b6. 

XXV  is  quadriannulate,  bi  and  b2  being  smaller  than  a2,  which  is 
again  slightly  smaller  than  aj.  Across  the  latter,  traces  of  the  furrow 
b$lbd  may  be  detected.  Following  XXV  are  two  small  rings  between 
which  the  anus  is  placed.  Although  there  are  no  visible  sensillae  to 
authenticate  the  determination,  these  are  interpreted  as  XXVI  and  XXVII 
respectively.

The  small  specimen  shows  immaturity  not  alone  in  the  condition  of  the 
reproductive  organs,  but  in  the  external  annulation.  Throughout  the 
middle  region  of  the  body  the  secondary  annuli  into  which  ar  and  aj 
are  divided  are  imperfectly  separated.  This  is  expressed  not  so  much  in 
their  relative  size,  which  is  scarcely  appreciably  less  than  in  the  mature 
specimen,  but  very  obviously  in  the  relative  shallowness  of  the  furrows 
bilb2  and  b$lb6  as  compared  with  bzla2  or  a2lb$.  Figure  4  is  a  careful 
camera  drawing  of  the  ventral  surface  of  this  specimen  when  mounted  in 
glycerine,  in  which  medium  the  ganglia  can  be  seen  quite  clearly  and  are 
also  represented  in  the  figure.  Generally  the  ganglia  lie  principally 
within  a2  throughout  the  quinqueannulate  region.  The  subcesophageal 
complex  is  in  VI  and  VII  and  the  supracesophageal  chiefly  in  VI.  On 
the  dorsal  surface  the  furrow  a2\b$  is  distinctly  deeper  than  &2la2,  result- 
ing in  the  natural  division  of  the  five  annuli  into  two  groups  of  three  and 
two  respectively. 

Alimentary  Canal. — The  upper  lip  (prostomium)  is  somewhat  wrinkled 
below,  but  lacks  any  definite  and  distinct  median  sulcus.  The  mouth  is 
small  in  the  preserved  specimens,  scarcely  larger  than  in  a  nephelid  in 
the  larger,  but  relatively  larger  in  the  smaller  one.  Jaws  are  absent, 
though  the  median  dorsal  one  is  probably  represented  by  a  small  rounded 
tubercle  occupying  the  corresponding  position  and  surrounded  by  a  shallow 
trench,  immediately  laterad  to  which  is  a  pair  of  broad,  low,  longitudinal 
muscle  columns,  and  again  beyond  these  a  similar  pair  of  narrower  ones, 
but  no  trace  of  lateral  jaws.  Muscles  and  gland  ducts  enter  the  dorsal 
tubercle,  but  there  are  no  teeth.  A  low,  narrow  fold  passes  between  the 
buccal  chamber  and  pharynx  dorsally,  but  fades  out  ventrally. 

The  pharynx  (Plate  XLIX,  fig.  9)  is  capacious  and  extends  to  the 
region  of  the  genital  pores  in  the  middle  of  XII.  Its  inner  surface  is 
thrown  into  slightly  marked  longitudinal  muscular  ridges.  These  begin 
anteriorly  as  a  dorsal  pair  and  a  median  ventral  one,  alternating  with 
three  much  narrower  ones.  Each  of  the  larger  set  almost  immediately 
divides  into  several,  so  that  for  the  greater  length  of  the  pharynx  ten  or 
twelve  ridges  are  recognizable.  None  of  these  is  strongly  marked  and  the 
internal  surface  of  the  pharynx  is  nearly  smooth  and  regular,  but  shows 
a  slight  tendency  toward  a  triangular  section. 

A  stomach  of  very  simple  character  extends  from  XIII  into  XIX,  where 
it  passes,  without  any  very  sharp  demarkation,  into  the  intestine.  Seven 


MOORE:   HIRUDINEA  OF  SOUTHERN  PATAGONIA.  673 

valves,  which  correspond  in  position  to  the  preganglionic  muscular  sheets, 
divide  it  into  as  many  slight  sacculations,  the  posterior  ends  of  the  last 
of  which  are  produced  into  a  pair  of  quite  rudimentary  caeca,  of  such 
small  size  and  so  closely  embracing  the  intestine  that  they  were  entirely 
overlooked  upon  the  first  examination.  They  scarcely  extend  beyond 
the  limits  of  the  neural  annulus  of  XIX. 

The  intestine  is  somewhat  distended  with  food,  to  which,  in  contrast  to  the 
emptiness  of  the  s'tomach,  the  somewhat  greater  diameter  of  the  former  is 
probably  due.  Its  walls  are  excessively  thin  and  delicate  and  somewhat 
regularly,  but  slightly,  sacculated  for  the  anterior  half.  It  reaches  to  XXIV, 
beyond  which  a  short  rectum  extends  to  the  anus.  That  this  species  is 
not  a  habitual  blood-sucker,  but,  like  our  common  Hcemopis  marmora^is, 
subsists  chiefly  on  small  invertebrate  animals  and  the  organic  contents  of 
mud,  is  shown  by  the  contents  of  the  intestine  and  stomach,  which  consist 
of  remains  of  tubificid  worms,  rhabdocoele  planarians  and  diatoms. 

Reproductive  Organs. — The  reproductive  organs  (Plate  L,  fig.  12), 
while  approaching  in  character  most  closely  those  of  Hcemopis,  yet  exhibit, 
if  the  single  example  dissected  be  entirely  normal,  a  number  of  striking 
peculiarities.  The  pairs  of  testes  occupy  the  interganglionic  intervals 
from  XIV/XV  to  XXII/XXIII  ventrad  of  the  alimentary  canal.  The 
first  pair  presents  the  ordinary  appearance,  but  the  remaining  eight  are  all 
double,  two  closely  appressed  but  perfectly  distinct  spheroidal  testes  with 
separate  efferent  ducts  occupying  each  interval.  The  actual  number  of 
testes  is,  therefore,  at  least  seventeen  pairs  and,  as  the  vasa  deferentia 
extend  some  distance  posterior  to  the  last,  it  is  probable  that  additional 
material  would  permit  of  the  demonstration  of  at  least  one  more  pair ;  and 
a  pair  may  also  occur  at  XIII/XIV.  Both  the  vasa  efferentia  and  vasa 
deferentia  are  excessively  slender,  but  the  latter  in  particular  are  rendered 
very  conspicuous  by  a  thick  covering  of  pear-shaped  groups  of  gland  cells, 
which  are  far  more  thickly  clustered  dorsally  than  ventrally.  Anterior  to 
the  testicular  region  the  glands  diminish  in  number  and  disappear  alto- 
gether in  somite  XII.  At  the  same  time  the  walls  of  the  sperm  duct 
acquire  greater  firmness  and  it  may  be  traced  as  a  tortuous  tube  as  far 
forward  as  the  position  of  the  male  pore,  where  it  bends  mesially  in  a 
recurrent  limb. 

In  somites  XIV  and  XV  each  vas  deferens  becomes  converted  into  a 
closely  coiled,  twisted  and  massed  tube  with  thick  walls  and  of  irregular

diameter,  the  epididymis.  This  passes,  without  any  enlargement  into  a 
special  sperm  sac,  into  a  short  thick  ductus  ejaculatorius  which,  without  any 
apparent  change  in  its  diameter,  is  lost  at  once  in  the  substance  of  the 
prostate  region  of  the  atrium,  into  which  it  enters.  The  atrium  is  straight 
—  not  bent  on  itself — and  is  chiefly  remarkable  for  the  great  size  of  its 
prostate  region,  which  projects  freely  caudad  beyond  the  point  of  entrance 
of  the  ducts  fora  distance  equal  to  more  than  one-fourth  of  the  entire  length 
of  the  atrium,  and  reaches  beyond  ganglion  XIX.  This  entire  region  is 
covered  with  a  layer  of  prostate  glands.  Anterior  to  the  ducts  the  atrium 
becomes  a  thick-walled  muscular  tube  (the  penis  sheath)  which  is  much 
narrower  than  the  prostate  region  and  tapers  somewhat  to  the  external 
end.  It  is  unfortunate  that  no  material  was  available  for  sectioning  to 
throw  light  upon  the  structure  especially  of  the  prostate  end  of  the  atrium. 

The  female  organs  (Plate  L,  fig.  12)  consist  of  a  single  ovary  (that  of 
the  left  side  being  probably  abnormally  absent)  lying  in  the  posterior  part 
of  somite  XII.  The  right  oviduct  (the  left  being  absent)  enters  a  well- 
marked  glandula  albuginea,  within  which  it  is  somewhat  coiled.  It  emerges 
as  the  common  oviduct,  which  is  not  very  clearly  differentiated  from  the 
glandula,  and  enters  the  posterior  end  of  the  vagina,  which  is  somewhat 
enlarged  but  lacks  a  distinctly  separated  ovisac  at  this  point.  The  entire 
female  organ  is  sharply  bent  on  itself  at  the  point  where  the-  oviduct  passes 
into  the  vagina  or  uterus.  The  nerve  cord  passes  to  the  left  of  the  terminal 
end  of  both  atrium  and  vagina. 

In  following  Blanchard  in  placing  this  species  in  Semiscolex,  I  have 
simply  accepted  his  determination,  as  I  have  never  had  the  opportunity  of 
dissecting  any  other  species  of  that  genus,  and  Kinberg's  description  is 
itself  insufficient.  Verrill's  Semiscolex  grandis  and  Forbes'  Semiscolex 
terrestris  are  very  different  and  both  are  true  species  of  Htzmofiis,  though 
the  absence  of  teeth  in  the  former  may  be  considered  by  some  as  a  suffi- 
cient basis  for  generic  separation.  Semiscolex  variabilis  also  evidently 
stands  with  Hcemopis  in  the  distichodont  division  of  the  Hirudinidae,  for, 
although  the  alimentary  canal  differs  from  that  of  Hamopis  and  resembles 
such  a  nephelid  as  Trocheta  in  the  rudimentary  jaws,  valvular  stomach  and 
all  but  absent  caeca,  it  has  the  proportions  of  and  can  readily  be  derived 
from  that  of  Hczmopis.  The  reproductive  organs  resemble  the  latter  genus 
in  the  length  of  the  vagina  and  penis  sheath,  the  enlarged  prostate,  etc., 
though  in  the  absence  of  any  special  sperm  and  ovarian  sacs  on  the  ducts 
it  rather  approaches  Hirudo  and  its  allies. 


MOORE:   HIRUDINEA  OF  SOUTHERN  PATAGONIA.  675 

Semiscolex  variabilis  appears  to  be  a  small  leech.  Blanchard's  speci- 
mens varied  from  10  to  37  mm.  in  length.  The  smallest  example  here 
described  measures  8  mm.,  the  largest,  which  is  poorly  preserved,  about 
23  mm.,  and  the  individual  which  furnished  most  of  these  notes  and  is 
represented  of  natural  size  in  fig.  i  has  the  following  measurements. 

Length,  2 1      mm. 

Anterior  end  to  male  pore,  6.5  mm. 

Width  at  male  pore,  2.  i  mm. 

Greatest  width  (XX),  3.6  mm. 

Diameter  of  posterior  sucker,  1.3  mm. 

Depth  at  male  pore  (about),  .8  mm. 

Greatest  depth  (about),  1.4  mm. 

Two  specimens  come  from  a  "large  spring  30  miles  above  Sierra  Oveja, 
Rio  Chico,  Feb.,  1899,"  Station  22  ;  the  third  is  from  a  "  drying-up  pool 
near  Arroyo  Eke,  Alt.  2100  ft.,  Feb.,  1899,"  Station  43. 

GLOSSIPHONIA  DUPLICATA  sp.  nov. 

(Plates  XLIX,  Fig.  10;  L,  Figs.  16-22.) 

This  species  resembles  G.  (Helobdella)  scutifera  R.  Blanchard,  but  is 
readily  distinguished  by  the  distinctly  double  annuli,  the  form  of  the 
nuchal  plate,  the  metameric  color  pattern,  etc. 

Without  exception  all  of  the  very  large  number  of  preserved  specimens 
are  stout  and  thick,  less  wide  and  flattened,  but  much  deeper  and  more 
strongly  convex  dorsally  than  examples  of  G.  scutifera  preserved  in  the 
same  bottles.  The  anterior  end  is  somewhat  slender,  the  posterior 
broadly  rounded,  the  greatest  width  being  at  about  the  beginning  of  the 
posterior  third.  The  anterior  sucker  is  small,  with  a  contracted  opening 
and  thick  margin  ;  the  prostomium  prominent.  In  almost  all  of  the 
specimens  a  low  elevation  arises  from  the  middle  of  the  sucker,  with  a 
deep  groove  bounding  it  anteriorly.  The  mouth  is  rather  large,  situated 
in  a  thickening  which  represents  the  ventral  portion  of  somite  III,  and  is 
the  center  of  several  radiating  furrows  (Plate  L,  fig.  18). 

The  contracted,  thick-rimmed  posterior  sucker  is  so  strongly  directed 
ventrad  that  it  is  entirely  concealed  from  above  (Plate  L,  figs.  19  and  20). 

Following  are  the  measurements  of  the  type  specimen,  than  which 
some  examples  are  several  millimeters  longer,  as  well  as  relatively  deeper.

Annulation. —  Somites  I  and  II  are  found  in  the  preocular  lobe,  across 
which  a  very  faint  furrow  can  usually  be  detected  and  is  always  quite 
evident  in  the  larger  specimens.  Ill  is  biannulate,  the  first  annulus 
larger.  IV  is  also  biannulate,  the  anterior  annulus  bearing  the  single 
pair  of  eyes,  which  are  generally  lightly  pigmented  and  consequently  in- 
conspicuous. This  somite  is  usually  a  trifle  longer  than  III,  but  in  some 
examples  they  are  equal.  The  example  figured  is  slightly  abnormal,  the 
left  half  of  the  furrow  IV/V  being  displaced  on  the  dorsal  side.  V  is 
likewise  biannulate,  but  is  considerably  longer  dorsally,  where  the  enlarged 
anterior  annulus  is  quite  distinctly  subdivided  by  a  furrow,  which  separates 
a  smaller  ai  from  a  larger  a2.  This  furrow  ends  at  the  margins  of  the 
lips  so  that  ventrally  there  is  no  trace  of  this  subannulation  (Plate  L, 
figs.  17,  18  and  22). 

Although  VI  must  be  reckoned  as  a  triannulate  somite  both  above  and 
below,  it  does  not  show  the  typical  condition,  inasmuch  as  ai  and  a2  are 
rather  closely  united  on  the  ventral  side,  and  aj  is  the  only  annulus 
which  exhibits  any  trace  of  that  development  of  secondary  annuli  which 
is  so  characteristic  of  this  species  among  its  close  allies,  and  even  this 
trace  is  usually  wanting. 

Somite  VII  is  the  first  typical  one.  The  three  annuli  are  of  about 
equal  size  and  each  is  usually  distinctly  subdivided  into  two  nearly  equal 
secondary  rings  by  a  cross-furrow,  which  is  especially  well-marked  on  ai 
and  aj,  and  much  less  distinct  or  even  absent  ventrally.  These  cross- 
furrows  correspond  in  position  with  superficial  annular  lacunae  which 
encircle  each  primary  ring  of  the  complete  somites,  and  they  have  a  con- 


MOORE:   HIRUDINEA  OF  SOUTHERN  PATAGONIA.  677 

stant  relation  to  the  bands  of  circular  muscles.  Each  primary  annulus 
possesses  five  of  these  bands,  between  the  second  and  third  of  which  the 
furrow  passes  on  ai  and  between  the  third  and  fourth  on  0.2  and  <zj. 
VII  aj  is  somewhat  swollen  at  the  mid-dorsal  line,  where  also  the  furrow 
VII/VIII  may  become  obliterated  for  a  short  distance  owing  to  the 
development  of  the  nuchal  gland  on  the  succeeding  somite.  The  nuchal 
plate  may  sometimes  slightly  overlap  VII  aj,  or  the  latter  may  be  some- 
what constricted  mesially  by  the  glandular  swelling.  In  some  examples 
the  cross-furrows  are  not  visible  on  VII  and  they  are  always  less  distinct 
than  on  the  larger  annuli  of  VIII  and  succeeding  somites. 

VIII  is  chiefly  remarkable  from  the  presence  of  the  nuchal  gland.  This 
is  confined  to  az,  which,  as  a  consequence,  is  swollen  and  more  or  less 
elongated  in  the  median  dorsal  region.  The  horny  plate  secreted  by  the 
gland,  which  it  covers  like  a  scale,  is  remarkably  thick  and  conspicuous. 
In  color  it  has  a  very  dark  brown  center  and  a  paler  border.  Unlike  G. 
stagnalis  it  is  broader  than  long,  anteriorly  very  convex,  posteriorly  slightly 
convex  or  straight.  It  slightly  overlaps  or  just  reaches  VIII  #<?  and  just 
reaches  the  furrow  VII/VIII  anteriorly.  But  little  change  is  noticeable 
in  the  character  of  the  somites  to  XXIII  inclusive,  though  the  secondary 
furrows  are  frequently  more  distinct  on  the  somites  immediately  succeed- 
ing the  region  of  the  genital  pores. 

On  XXIV,  which  remains  triannulate,  the  secondary  furrow  is  present 
on  ai  only  and  even  there  has  become  less  distinct.  On  the  ventral  side 
the  annuli  of  this  somite  are  crowded  together  by  the  posterior  sucker. 
XXV  is  biannulate  and  of  much  reduced  length.  The  first  annulus  is 
about  one  half  larger  than  the  second  and  about  equal  to  the  contiguous 
annulus  of  XXIV.  XXVI  is  faintly  biannulate,  aj  being  very  narrow 
and  indistinct.  XXVII  is  uniannulate  and  is  cut  into  two  halves  by  the 
anus,  which  thus  lies  just  posterior  to  XXVI  (Plate  L,  figs.  19,  20 
and  21). 

Pigmentation.  —  From  many  of  the  specimens  the  pigment  had  faded 
altogether,  but  all  of  those  in  which  this  is  not  the  case  show  a  very  evi- 
dent metameric  arrangement,  resulting  in  many  cases  in  a  strongly  annu- 
lar pattern,  which  is  dependent  on  the  disposition  of  the  muscles.  In  a 
typical  example  (Plate  L,  fig.  17)  the  ground  color  is  a  faintly  mottled,  very 
pale  brown,  which  deepens  on  the  margins  and  fades  to  a  gray  on  the  ven- 
tral surface.  Dorsally,  two  broad,  ill-defined,  longitudinal  bands  extend 


678  PATAGONIAN    EXPEDITIONS:     ZOOLOGY. 

nearly  the  entire  length.  They  are  indistinct  anterior  to  the  nuchal  gland 
but  are  usually  conspicuous  from  that  point  to  the  anus.  The  median 
interspace  between  the  bands  corresponds  to  nine  longitudinal  muscle 
bundles,  the  bands  themselves  to  five  each  (they  are  formed  of  six  lines 
of  pigment  cells  corresponding  to  six  intermuscular  lines),  and  the  dis- 
tance separating  them  from  each  margin  to  eleven. 

Annulus  ai  of  each  somite  from  VI  to  XXVI  inclusive  is  much  more 
heavily  pigmented  than  the  others,  and  the  pigment  is  especially  aggre- 
gated on  its  posterior  half,  the  b2  constituent.  Thus  in  such  typical  cases, 
the  dorsum  is  marked  by  well-defined,  narrow,  metameric,  transverse  bands, 
which  become  fainter  anteriorly,  where  they  can  seldom  be  traced  beyond 
VI,  and  altogether  diffuse  posteriorly  on  XXV  and  XXVI.  These  trans- 
verse bands  extend  the  entire  width  of  the  dorsum,  both  mesiad  and 
laterad  of  the  longitudinal  stripes.  Other  examples  are  less  typical  and 
show  the  pigment  spreading  over  aj  as  well  as  bi,  but  the  former  never 
becomes  so  dark  and  is  brown  rather  than  blackish  ;  a2  always  remains 
paler.  The  characteristic  pattern  is  due  to  black  pigment  cells  deep- 
seated  between  the  muscle  bands. 

Reproductive  Organs. — The  male  pore  is  situated  at  ~X.\\aila2y  the 
female  at  XII  a2la^.  The  former  is  the  more  conspicuous,  and  in  some 
specimens,  but  not  in  the  type,  is  in  the  center  of  an  elliptical  disc,  which 
is  wedged  between  the  two  contiguous  annuli.  There  are  six  pairs  of 
testes  (Plate  XLIX,  fig.  10)  of  globoid  form  alternating  with  the  gastric 
caeca  and  filling  up  the  spaces  between  these.  Dorso-ventrally  they  are 
deeper  than  the  caeca,  reaching  the  same  dorsal  level,  but  extending  to  a 
lower  ventral  one.  Though  inter-metameric  in  position,  they  probably 
belong  to  the  somites  in  which  their  posterior  halves  lie,  consequently  to 
XIV  to  XIX  inclusive.  The  vasa  efferentia  and  vasa  deferentia  are 
excessively  delicate  and  can  be  traced  only  with  difficulty.  The  vas 
deferens  of  each  side  passes  dorsad  of  the  caeca  and  mesiad  of  the  testes. 
Reaching  the  posterior  end  of  XII,  it  bends  sharply  mesiad,  traversing 
muscles  and  pharyngeal  glands  ventrad  to  the  ducts  of  the  latter,  and 
reaches  the  ventral  sinus,  through  which  it  extends  caudad,  increasing, 
first  abruptly  and  then  gradually  in  diameter.  The  change  from  the 
minute  vas  deferens  to  the  larger  epididymis  takes  place  in  XIII.  The 
long  epididymal  loop  (sperm  sac)  thus  formed  is  very  conspicuous, 
reaching  to  the  posterior  end  of  XIX,  and,  being  considerably  convoluted 


MOORE:   HIRUDINEA  OF  SOUTHERN  PATAGONIA.  679 

and  coiled  about  its  fellow,  would  if  straightened  out,  have  a  total  length 
somewhat  greater  than  the  entire  animal.  The  external  limb  of  the  loop 
has  a  slightly  larger  and  more  uniform  diameter  than  the  internal  and  its 
walls  have  a  firmer  consistency,  which  increases  as  the  muscular  structure  of 
the  ductus  ejaculatorius  is  assumed.  The  difference  however  is  slight 
In  one  specimen  the  left  epididymal  loop  passes  ventrad  to  the  right  lateral 
nerve  of  XIX  and  then  bends  forward  dorsad  to  the  nerve  cord  and 
reaches  to  ganglion  XVIII.  Just  before  entering  the  prostate  or  atrial 
cornu,  the  duct  becomes  constricted  for  a  short  distance.  The  atrium  con- 
sists of  a  very  small  common  bursa,  opening  to  the  exterior  and  situated 
entirely  beneath  the  nerve  cord,  and  of  two  large  globoid-fusiform  or 
broadly  ovate  cornua,  which  diverge  from  beneath  the  nerve  cord  and 
project  prominently  cephalad,  laterad  and  dorsad  within  the  limits  of 
somite  XII.  Their  somewhat  narrowed  apices  are  joined  by  the  sperm 
ducts  (Plate  XLIX,  fig.  10). 

The  ovarian  sacs  (Plate  XLIX,  fig.  10)  have  no  anterior  lobes  (or  at 
least  none  are  discernible  in  several  dissections)  and  the  two  simple  sacs 
of  irregular  form  lie  in  close  contact  in  the  ventral  sinus  between  the  nerve 
cord  and  the  sperm  sacs.  In  the  case  where  they  exhibit  the  greatest 
development,  the  left  sac  reaches  to  ganglion  XVIII,  the  right  to  XVII. 

Alimentary  Canal. — The  proboscis  (Plate  L,  fig.  16)  is  stout,  nearly 
cylindrical  but  very  slightly  tapering;  the  anterior  end  is  but  little  contracted 
and  truncate  with  fine  denticulations  on  the  margin.  It  reaches  in  the 
retracted  state  from  VII  ai  to  XII  aj  and  receives  at  its  slightly  enlarged 
base  the  pair  of  thick  ducts  of  the  pharyngeal  glands.  These  are  a  loose, 
diffuse  mass  of  unicellular  glands  occupying  on  each  side  the  lateral  por- 
tions of  somites  XII  to  XIV  and  to  a  less  extent  of  XL  There  is  no 
median  lobe  and  the  bundles  of  ducts  from  each  side  remain  independent 
of  each  other.  A  short,  thin-walled  oesophagus  extends  through  XIII  to 
the  stomach  beginning  in  XIV. 

The  stomach  is  thin-walled  throughout  and  resembles  that  of  G.  lineata 
(Verrill)  most  closely,  the  caeca  being  better  developed  than  is  usual  in 
G.  stagnalis.  Six  pairs  of  these  caeca  occur.  The  first,  in  XIV,  are 
very  small  and  may  be  absent  on  one  side,  or  otherwise  asymmetrically 
developed.  In  XV  to  XVIII  are  four  pairs  of  slender  caeca  of  simple 
form,  which  (when  empty)  extend  nearly  half  way  to  the  margins  of  the 
body.  The  pair  of  large,  posteriorly  directed  ones  arises  in  XIX  and 


680  PATAGONIAN   EXPEDITIONS  :     ZOOLOGY, 

extends  to  XXIV  inclusive.  The  intestine  has  the  usual  four  pairs  of 
lateral  caeca  in  XX  to  XXIII  inclusive,  all  of  which  are  dorsad  of  the 
large  gastric  caeca.  The  first  three  pairs  are  sacculated,  the  last  smooth. 
Each  of  the  gastric  and  intestinal  caeca  arises  directly  over  the  correspond- 
ing ganglion  and,  with  the  exception  of  the  last  gastric,  is  confined  to  the 
limits  of  one  somite. 

This  species  must  be  exceedingly  abundant  throughout  the  region  of 
Mr.  Hatcher's  explorations,  as  the  following  list  of  the  localities  and  num- 
ber of  specimens  will  show.

GLOSSIPHONIA  SCUTIFERA  (Blanchard). 

The  reproductive  organs  of  Glossiphonia  (Helobdella]  sciitifera  are  inter- 
mediate in  character  between  those  of  G.  duplicata  and  G.  michcelseni  in 
that  the  vas  deferens  does  not  abruptly  enlarge  to  form  the  sperm  sac  im- 
mediately after  turning  caudad,  as  in  the  former,  nor  yet  retain  its  tenuity 
for  several  somites  further  back,  as  in  the  latter,  but  passes  first  into  a 
region  of  intermediate  diameter  before  again  increasing  to  the  full  size  of 
the  sperm  sac.  That  these  differences  are  constant,  seems  certain  from 
the  verification  of  the  observation  in  repeated  dissections.  The  ductus 


MOORE:    HIRUDINEA  OF  SOUTHERN  PATAGONIA.  68 1 

ejaculatorius  is  relatively  longer  than  in  G.  duplicata  and  frequently  makes 
one  or  even  two  turns  of  a  spiral  in  passing  to  the  prostate  cornua  of  the 
atrium. 

With  the  exception  that  the  gastric  caeca  are  considerably  longer,  the 
alimentary  canal  differs  in  no  important  feature  from  that  of  G.  duplicata. 

There  is  never  any  appearance  of  subdivision  of  the  annuli,  although 
the  superficial  annular  lacunae  are  developed  as  in  G.  duplicata.  In  all  of 
the  specimens  examined  by  me  the  nuchal  plate  is  thin  and  transversely 
elongated,  sometimes  merely  occupying  a  chink  between  VII  aj  and  VIII  ai. 

Blanchard  found  this  species  to  be  very  numerous  in  the  collections 
from  the  region  bordering  on  the  Straits  of  Magellan.  In  the  uplands  it 
seems  to  be  less  frequent  than  some  of  its  allies.

GLOSSIPHONIA  SIMPLEX  sp.  nov. 

(Plates  XLIX,  Fig.  II ;  L,  Figs.  15,  23,  24.) 

The  nearest  ally  of  this  species  is  Glossiphonia  lineata  (Verrill),  from 
which  it  is  distinguished  by  having  somites  III  and  IV  uniannulate  in- 
stead of  biannulate,  and  a  single  series  of  cutaneous  papillae  present  on 
every  annulus  instead  of  three  series  developed  on  the  neural  annuli  only, 
as  in  G.  lineata. 

G.  simplex  is  broad,  flat-bodied  and  thin,  in  which  it  contrasts  greatly 
with  G.  (Helobdelld]  michcelseni  R.  Blanch.,  which  in  annulation  and 
anatomy  it  closely  resembles.  The  annuli  are  very  distinct,  and  the 
margins,  especially  posteriorly,  almost  serrated.  The  oral  sucker  is  small, 
with  thick  margins  and  a  rather  deeply  depressed  center,  in  the  anterior 
part  of  which  the  large  mouth  is  situated  in  somite  III.  The  deeply  pig- 
mented  eyes  are  in  IV  and  are  very  conspicuous,  owing  to  their  large 
size  and  the  nearly  color  less  areain  which  they  lie.  A  median,  slightly 
enlarged  area  on  annulus  VIII  ai  represents  a  small  nuchal  gland,  but 
there  is  no  nuchal  plate,  except  in  two  specimens,  in  which  it  is  very  thin 


682  PATAGONIAN    EXPEDITIONS!     ZOOLOGY. 

and  of  nearly  the  form  shown  by  G.  scutifera.  The  posterior  sucker  is 
relatively  larger  than  in  G.  michcelseni  and,  unlike  that  species,  faces 
ventrad  and  extends  further  forwards.  At  the  same  time  its  posterior 
margin  is  widely  exposed  from  above.  Its  surface  is  roughened  with 
numerous  minute  papillae  (Plate  L,  fig.  24).  A  somewhat  irregular  series 
of  small  cutaneous  papillae  passes  along  the  median  dorsal  line,  usually 
occurring  on  every  annulus  from  the  genital  somite  nearly  to  the  anus. 
Anterior  to  the  genital  pores  they  usually  fade  out  and  may  be  absent 
from  several  of  the  preanal  somites  also.  These  papillae  form  a  strictly 
median  series,  not  a  broken  double  series  as  in  G.  lineata.  They  have  a 
nearly  constant  relative  size  on  the  three  annuli  of  a  somite,  being  longest 
on  a2  and  smallest,  and  sometimes  even  wanting  on  ai.

Greatest  width  (XVIII),  3.7  mm. 
Depth  at  XVIII  about,  .8  mm. 

Annulation.  —  I  and  II  are  coalesced.  Ill  and  IV  are  uniannulate,  the 
latter  containing  the  eyes.  V  is  biannulate,  the  first  annulus  about  as 
long  as  the  entire  somite  IV,  the  second  (0,3}  about  three  fifths  as  long. 
The  furrow  V  aila2  is  sometimes  faintly  developed.  VI  is  triannulate, 
a2  generally,  but  not  invariably,  the  longest. 

The  annuli  of  the  complete  somites,  of  which  there  are  nineteen  (VI  to 
XXIV),  have,  with  the  exception  of  the  first  and  the  last,  which  may  vary, 
a  constant  relative  size  ;  a2  is  the  longest,  ai  the  shortest ;  ai  has  four 
circular  muscle-bands  on  the  dorsal  side,  a2  and  0,3  have  each  five,  except 
that  in  most  cases  XXIV  aj  has  but  four.  XXV  is  biannulate  both  dor- 
sally  and  ventrally.  XXVI  and  XXVII  are  uniannulate,  the  latter  deeply 
cut  by  the  large  anus.  One  distinct  postanal  annulus  is  differentiated 
(Plate  L,  figs.  23  and  24). 

Unlike  most  of  the  material  in  this  collection,  which   was  not  suitably 


MOORE:   HIRUDINEA  OF  SOUTHERN  PATAGONIA.  683 

preserved  for  the  purpose,  many  examples  of  this  species  exhibit  a  part  of 
the  dorsal  sensillae.  In  no  case  could  the  full  number  be  detected  on  any 
one  somite  and  it  is  possible  that  the  dorso-median  series  may  be  wanting. 
At  any  rate  the  pair  most  median  in  position  are  separated  by  a  wide 
interval,  equal  to  about  half  the  width  of  the  body.  Plate  L,  fig.  24,  shows 
their  arrangement  on  somite  XXIV  of  an  individual  in  which  they  were 
especially  prominent. 

Pigmentation.  —  The  color  above  is  a  pale  brownish,  with  a  broad 
median  dark  area  (equal  to  two  thirds  of  the  width  of  the  body)  marked 
by  twenty-four  fine  longitudinal  lines  of  black  pigment  cells,  which  corre- 
spond to  as  many  intermuscular  intervals.  The  two  most  mesial  of  these 
are  much  heavier  than  the  others  and  tend  to  unite  across  the  median  line. 
All  of  these  lines,  and  consequently  the  area,  tend  to  fade  out  both  ante- 
riorly and  posteriorly.  More  superficial  than  the  longitudinal  striae  are 
small  irregular  blotches  and  transverse  dashes  which  lie  between  the  cir- 
cular muscles  and  are  more  or  less  thickly  scattered  over  the  entire  dorsal 
surface  from  margin  to  margin,  except  anteriorly,  where  they  are  very  few, 
and  further  forward  altogether  absent.  These  spots  give  to  the  dorsum 
a  speckled  appearance  not  unlike  what  is  seen  in  many  examples  of  G. 
scutifera.  Of  course  some  individuals  are  lighter,  some  darker.  Many 
examples  have  two  or  three  large  irregular  whitish  spots,  from  which  pig- 
ment is  nearly  or  quite  absent,  in  the  posterior  part  of  the  body.  A  some- 
what unusual  feature  in  members  of  the  genus  is  the  presence  on  the 
ventral  surface  of  submarginal  series  of  irregular,  more  or  less  confluent 
dark  spots,  forming  a  band  on  each  side.  They  are  confined  to  the  middle 
third  of  the  body. 

Reproductive  Organs. — The  genital  pores  are  separated  by  a  single 
annulus,  the  male  being  at  XII  aila2,  the  female  XII  a2laj.  There  are 
six  pairs  of  testes  arranged  as  in  G.  duplicata.  The  vas  deferens  is  dorso- 
laterad  of  the  testes  and  is  met  by  the  six  delicate  vasa  efferentia,  which 
arise  from  the  dorso-lateral  aspect  of  the  testicular  walls.  After  reaching 
somite  XII  the  vas  bends  back  into  a  long  epididymal  loop  as  in  G.  dupli- 
cata, but,  instead  of  becoming  enlarged  at  once  to  form  the  sperm  sacs, 
as  in  that  species,  it  reaches,  without  any  change  in  its  diameter  or  the 
character  of  its  wall,  as  far  caudad  as  XVI  or  XVII,  at  which  point  it 
abruptly  passes  into  the  sperm  sac.  The  latter  may  extend  as  far  as 
XX,  and  the  anterior  end  of  its  efferent  limb  becomes  more  or  less  coiled 


684  PATAGONIAN  EXPEDITIONS!  ZOOLOGY. 

and  looped  in  XII  or  even  extends  into  XL  The  atrium  and  ductus 
ejaculatorius  exhibit  no  features  requiring  special  comment,  which  is 
true  of  the  ovaries  also  (Plate  L,  fig.  15).  The  collection  includes  one 
specimen  of  8  mm.,  bearing  eggs  arranged  in  a  compact  group  at  the 
widest  part  of  the  body.  Others  exhibit  indications  of  having  recently 
borne  eggs  or  young. 

Alimentary  Canal. — The  pharynx  is  about  as  stout  as  that  of  G.  lineata, 
and  when  retracted  reaches  from  VIII  to  XII.  Its  free  end  is  provided 
with  muscular  denticulations.  In  XIII  the  thick  ducts  of  the  pharyngeal 
glands  open  into  its  posterior  end.  These  ducts  are  provided  with  a 
stout  muscular  sheath,  are  single  on  each  side  and  lack  any  cross  connec- 
tion. The  glands  consist  of  a  few  cells  which  are  individually  of  larger 
size  than  in  G.  duplicata  and  are  distributed  sparingly  over  somites  XI  to 
XV  or  even  beyond.  There  are  usually  only  five  pairs  of  gastric  caeca, 
the  first  four  of  which  are  simple  and  of  nearly  equal  size,  the  fifth,  which 
arises  in  XIX,  is  somewhat  spacious  and  reaches  XXII.  The  intestinal 
caeca  are  four  pairs,  alternately  larger  and  smaller,  and,  with  the  excep- 
tion of  the  last,  curve  somewhat  cephalad  above  the  last  pair  of  gastric 
caeca  (Plate  XLIX,  fig.  n).

MOORE:   HIRUDINEA  OF  SOUTHERN  PATAGONIA.  685 

GLOSSIPHONIA  MICH^ELSENI  (Blanchard). 

(Plate  L,  Figs.  13,  14.) 

Among  the  peculiarities  of  the  reproductive  organs  (Plate  L,  fig.  14) 
the  following  are  noteworthy.  There  are  epididymal  loops  (sperm  sacs) 
formed  by  the  vasa  deferentia  as  in  G.  duplicata,  G.  stagnalis,  etc.,  and 
usually  reaching  beyond  ganglion  XVIII.  In  one  respect  they  differ 
strikingly  from  those  of  G.  duplicata  and  as  closely  resemble  G.  simplex, 
viz.,  the  vasa  deferentia  after  turning  remain  of  extreme  tenuity  until 
reaching  XV  or  XVI,  that  is,  for  about  half  the  length  of  the  loops,  and 
then  suddenly  enlarge  into  the  sperm  reservoirs.  This  is  true  of  all  of  a 
considerable  number  dissected.  Before  entering  the  prostates,  the  duct 
is  thrown  into  several  deep  folds,  which  extend  anterior  to  the  atrium  even 
into  somite  XI. 

In  the  form  of  the  alimentary  canal  (Plate  L,  fig.  13),  as  indeed  in 
many  other  respects,  this  species  closely  resembles  Glossiphonia  nephe- 
loides  (Graf.)  (=  G.  elongata  Castle),  a  not  uncommon  species  in  Penn- 
sylvania, New  Jersey,  and  Massachusetts.  A  striking  difference  in  the 
digestive  tract,  however,  is  the  entire  absence  of  the  large  gastric  caeca, 
which  in  other  Glossiphoniae  arise  in  XIX,  and  in  G.  nepheloides  extend, 
according  to  Castle,  through  two  somites. 

The  mouth,  which  is  of  remarkably  large  size,  is  in  somite  III.  The 
pharynx,  which,  when  retracted,  reaches  from  VIII  to  a  point  just  caudad 
of  the  male  pore,  is  stout  and  may  be  extended  to  an  unusual  distance, 
in  some  cases  to  nearly  one  third  the  length  of  the  body.  It  is  nearly 
cylindrical,  but  tapers  somewhat  abruptly  at  the  free  end,  which  is  termi- 
nated by  nine  larger  muscular  denticulations,  arranged  in  three  sets  of 
three  each  and  alternating  with  three  smaller  ones.  Three  longitudinal 
muscular  ridges  continue  these  for  the  entire  length  of  the  pharynx  and 
give  to  its  lumen  the  usual  triangular  form.  They  terminate  at  the  point 
of  entrance  of  the  ducts  of  the  pharyngeal  glands  in  XII  or  XIII.  As 
in  most  small  glossiphonids  of  the  Helobdella  group,  these  glands  are 
strictly  paired.  In  this  species  they  consist  of  a  very  few  unicellular  glands 
of  large  size  arranged  in  a  loose  group  confined  mainly  to  XII  and  XIII, 
though  occasionally  extending  somewhat  into  the  immediately  adjacent 
somites.  The  ducts  are  in  one  pair,  of  large  size  and  strongly  muscular. 

A  short  oesophagus  gradually  widens  into  the  thin-walled,  somewhat

spacious  stomach  which  reaches  from  XIV  to  XIX  inclusive.  The  stomach 
increases  in  diameter  to  about  XVII,  behind  which  a  constriction  occurs, 
followed  by  a  rather  conspicuous  sacculation  in  XIX,  probably  represent- 
ing the  posterior  gastric  caeca  which,  however,  do  not  extend  at  all  caudad. 
Indeed  there  are  no  distinct  gastric  caeca  whatever.  Four  pairs  of  short, 
rather  wide  intestinal  caeca  are  crowded  into  XXI  and  XXII  and  are  fol- 
lowed after  a  constriction  by  a  somewhat  bulbous  dilatation.

any  other  of  the  six  species  included  in  the  collection.

HEMICLEPSIS  TESSELLATA  (Miiller)  Veydovsky. 

A  single  individual,  which  is  in  nowise  distinguishable  from  this  well- 
known  European  species,  was  collected  on  the  Rio  Chico. 

In  demonstrating  the  identity  of  Theromyzon  fallens  Philippi  with  this 
species  Blanchard  has  already  shown  that  its  range  extends  in  South 
America  as  far  south  as  Chili.  Inasmuch  as  it  is  widely  distributed, 
though  by  no  means  common,  in  North  America,  it  may  now  be  expected  to 
occur  generally  over  the  American  continent.  Hemiclepsis  tessellata  is  an 
excellent  example  of  the  wide  distribution  which  some  species  of  leeches

have  attained.  An  equally  notable  case  is  the  Glossiphonia  stagnalis 
(Linn.).  Blanchard  has  recorded  this  species  from  Paraguay1  and  Chili.2 
I  have  specimens  collected  by  Mr.  Trevor  Kincaid  in  Alaska  and  it 
abounds  in  all  parts  of  the  United  States,  Canada  and  Europe.

situ,  the  vagina  only  being  slightly  dis- 
placed to  the  right.  From  a  dissection 
of  specimen  shown  in  Fig.  i.  The  posi- 
tion of  the  vasa  efferentia  is  somewhat 
doubtful,  as  they  could  not  be  distinguished 
with  certainty  from  the  folds  of  the  vas 
deferens,  X  TT
