LIST  OF  THE  CONIDAE  OF  PUERTO  RICO 

By  GEEMAINE  L.  WARMKE 
Institute  of  Marine  Biology,  University  of  Puerto  Eico,  Mayaguez 

The  present  report  adds  five  species  of  Conidae  not  previously 
listed  for  Puerto  Rico  and  several  new  locality  records.  The 
finding  of  Conns  juliae  Clench  in  Puerto  Rico  extends  the  range 
of  this  species  from  Florida  to  the  West  Indies.  The  range 
of  Conus  centurio  Born  is  also  extended,  as  it  had  been  reported 
previously  only  from  Santo  Domingo,  (Clench,  1942).  A  total 
of  11  species  of  cones  have  been  found  to  date  in  Puerto  Rico. 
Locations  of  collecting  sites  are  shown  in  figure  1.  The  species 
reported  are  as  follows: 

Conus  regius  Gmelin 

Reported  as  C.  nehulosus  Solander  by  Dall  and  Simpson 
(1901)  from  Aguadilla.  Additional  records:  Between  Boqueron

(found  alive  by  A.  Phares)  ;  Rincon  Light  House;  Punta 
Cadena;  Mona  Island,  (found  alive  by  M.  McDowell).  Dead 
shells  very  common  on  the  beach.     Live  shells  found  in  reefs. 

Conus  mus  Hwass 

Reported  by  Dall  and  Simpson  (1901)  from  San  Juan; 
Aguadilla;  Ponce;  and  by  Clench  (1943)  from  San  Juan  and 
Mona  Island.  Additional  records :  Mayaguez ;  Punta  Guana- 
jibo ;  Punta  Arenas ;  Cabo  Rojo  Light  House ;  Guanica ;  between 
Patillas  and  Maunabo ;  Boca  de  Cangrejos ;  Punta  Maldonado ;

TAXONOMY  OF  SALT  MARSH   SNAIL,  OVATELLA 
MYOSOTIS,  IN  CENTRAL  CALIFORNIA 

By  EDWARD  G.  PAULSON 
Department  of  Zoology,  University  of  California,  Berkeley 

Early  in  the  course  of  an  investigation  of  the  ecology  of  the 
ellobiid,  Ovatella  myosotis,  in  central  California  salt  marshes, 
it  became  apparent  that  a  number  of  different  names  are  in 
current  usage  for  this  species.  Most  commonly  applied  is 
Phytia  setifer  Cooper,  1872,  but  also  to  be  found  are  Phytia 
myosotis,  Alexia  setifer  and  Alexia  myosotis.  The  following 
is  an  attempt  to  clarify  this  situation. 

The  history  of  the  genus  Phytia  Gray  1821  has  been  recently 
reviewed  by  Watson  (1943).  In  confirming  the  observations  of 
several  previous  workers,  particularly  those  of  Woodward 
(1903),  he  made  the  following  points:  (1)  The  generic  name 
Alexia  Leach  is  clearly  unavailable  for  this  group  since  it  had 
been  used  by  Stephens  for  a  genus  of  Coleoptera  before  its  first 
publication  by  Gray  in  1847,  and  (2)  the  name  Phytia  originated 
through  Gray's  unintentional  misspelling  of  Pythia  and  hence 
must  be  dropped  under  article  19  of  the  International  Rules. 
While  his  first  point  must  be  considered  definitely  established, 
some  doubt  has  been  expressed  of  his  interpretation  of  the  mode 
of  origin  of  Phytia  (see  Burch,  1945).  Although  direct  proof 
of  Gray's  original  intent  appears  lacking,  seemingly  the  indirect 
evidence  on  this  point,  as  amassed  by  Watson,  is  quite  conclusive. 
Particularly  pertinent  is  the  fact  that  Gray,  himself,  twice  cor- 
rected his  error  by  listing  Pythia  Gray,  1821  (not  Phytia)  in 
the  synonomy  of  this  genus  (in  1847,  Pythia  for  Alexia  and  in 
1857  for  Conovolus).  In  place  of  Phytia,  Watson  proposed 
Ovatella  Bivona  Bernardi,  1832,  as  the  oldest  available  name  for 
this  genus,  in  so  doing  accepting  Ovatella  punctata  Bivona 
Bernardi,  1832  (=  Auricula  firmini  Pyaredeu,  1826)  as  the  type 
of  this  originally  typeless  and  heterogeneous  assemblage.  Wat- 
son's suggestion,  however,  has  not  met  with  universal  adoption, 
and  thus  some,  such  as  Harry  (1947)  and  Morton  (1955),  follow 
him  in  the  use  of  Ovatella  while  others,  including  Burch  (1945) 
and  Morrison  (1951),  retain  Phytia.  Watson  is  followed  here 
in  the  application  of  the  name  Ovatella,  not  only  because  such  a 
change  luus  been   shown   to  be   technically  necessary,   but   also

because,  as  pointed  out  by  Morton  (1955),  this  eliminates  the 
frequent  source  of  confusion  inherent  in  the  retention  of  two 
such  similar  names  as  Phytia  and  Pythia  in  the  Ellobiidae. 

The  trivial  name  setifer  has  had  a  rather  confusing  history. 
In  his  original  description  of  Alexia  setifer  Cooper  (1872) 
stated,  "Shell  very  similar  to  A.  myosotis  (of  the  northern  At- 
lantic states)  but  the  young  provided  with  short  deciduous  bristles 
arranged  in  a  spiral  line  just  in  front  of  the  suture."  Such 
bristles,  however,  had  long  been  known  in  the  better  preserved 
specimens  of  Ovatella  myosotis  (see  Clarke,  1855).  Dall  (1885), 
after  comparing  the  shells  of  the  two  forms,  decided  that  they 
were  identical  and  listed  Alexia  setifer  as  a  synonym  of  Alexia 
myosotis.  In  1894,  Cooper,  apparently  accepting  Ball's  ob- 
servations, listed  this  form  as  Alexia  myosotis,  var.  setifer 
Cooper,  1872.  With  the  question  apparently  settled  then,  Dall 
(1921)  inexplicably  resurrected  Phytia  setifer  as  a  distinct 
species.  In  this  he  has  been  followed  by  most  later  workers 
such  as  Oldroyd  (1927),  Keen  (1937),  and  Morrison  (1950). 
Hanna  (1939),  however,  included  Phytia  myosotis  in  his  list  of 
''Exotic  Mollusca  in  California"  with  the  statement  that  no 
recent  published  record  of  a  careful  comparison  of  shells  could 
be  found.  Burch  (1945)  recently  has  discussed  this  problem, 
and  while  retaining  Phytia  setifer  as  a  distinct  species,  he  ex- 
pressed the  need  of  a  comparative  study  to  settle  this  question. 

Such  a  study  was  undertaken  by  the  author.  Forty  speci- 
mens of  Ovatella  myosotis  from  Europe  and  12  specimens  from 
the  east  coast  of  the  United  States  were  compared  with  over  300 
California  specimens  collected  from  San  Francisco  Bay,  Bodega 
Bay  and  Elkhorn  Slough.  In  making  this  comparison,  speci- 
mens of  height  greater  than  6.8  mm.,  possessing  a  thickened 
outer  lip,  were  arbitrarily  considered  to  be  mature.  The  posses- 
sion of  a  thickened  outer  lip  was  not  invariably  an  adequate  indi- 
cation of  maturity.  In  the  first  place,  a  thin  outer  lip  was  not 
found  to  be  a  certain  indication  of  sexual  immaturity  since 
such  individuals  were  frequently  found  copulating.  Further- 
more, the  resumption  of  growth  in  individuals  with  a  thickened 
outer  lip,  with  apparent  resorption  of  the  thickening,  was  found 
not  to  be  uncommon. 

Comparison  of  the  two  forms  revealed  complete  uniformity 
with  respect  to  the  following  characters:

Ratio    of    Height   to    Maximum   Diameter 


Color :  Hyaline  through  brown  and  purple,  with  complete 
intergradation  between.  Apex:  Asymmetrical,  exhibiting  re- 
duced heterostrophy.  Sculpture :  Apical  bulb  smooth,  toward 
end  of  first  whorl  acquiring  spiral  punctuations  which  in  the 
third  and  later  whorls  are  obscured  by  faint  longitudinal  stria- 
tions.  Bristles  present  below  the  suture.  Apertural  teeth: 
Inner  lip  (columella)  2-4.     Outer  lip  0-3.^ 

In  addition  the  ratio  of  height  to  maximum  diameter  was 
computed  for  all  specimens.  The  results  are  plotted  in  figure  1, 
which  compares  on  a  percent  basis  the  British  and  eastern  U.  S. 
samples  with  the  California  specimens. 

From  the  foregoing,  it  can  be  seen  that  there  is  sufficient  uni- 
formity and/or  overlap  in  all  critical  characters  examined  to 
demand  the  decision  that  the  two  forms  are  conspecific.  There- 
fore, I  suggest  that  the  form  previously  known  as  Phytia  setifcr 
Cooper,  1872  should  be  designated  as  Ovatella  myosotis  Drapar- 
naud. 

1  In  Europe  two  subspecies  of  Ovatella  myosotis  have  been  recognized 
on  the  basis  of  the  number  of  teeth  on  the  outer  lip.  Ovatella  myosotis 
myosotis  possesses  0-3  teeth  and  Ovatella  myosotis  denticiilatus  has  3-6 
teeth  on  tlie  outer  lip.  There  is  no  evidence  that  such  a  distinction  can 
be  made  in  Californian  material,  and  all  specimens  examined  must  be 
referred  to  Ovatella  myosotis  myosotis.

This  study  was  made  possible  through  the  generous  response 
of  many  people  to  my  requests  for  comparative  material.  Es- 
pecially to  be  thanked  are  Dr.  Myra  Keene,  Stanford  University ; 
Dr.  Leo  Hertlein  and  Mr.  Allyn  Smith,  California  Academy 
of  Sciences ;  Dr.  Rees  and  Dr.  Galbreath  of  the  British  Museum ; 
and  Dr.  Paul  Holle,  University  of  New  Hampshire.  Finally  I

ANATOMY  OF  MOELLENDORFFIA   (TRIHELIX) 
EUCHARISTUS   (PILSBRY) 

By  TADASHIGE  HABE 
Amakusa  Marine  Biological  Laboratory 

Through  courtesy  of  Dr.  Tokubei  Kuroda,  a  living  specimen 
of  Moellendorffia  (Trihelix)  eucharistus  (Pilsbry)  from  Sayo- 
mura,  Amami-Oshima,  one  of  the  Ryukyu  chain,  has  been  for- 
warded to  me.  This  species  is  rather  rare,  but  was  fortunately 
discovered  by  Mr.  Masataka  Ishimori  during  the  tour  of  his  col- 
lection in  1956-57.  This  is  a  first  opportunity  for  examination 
of  the  soft  parts  of  the  group,  as  well  as  the  species. 

This  species  seems  to  be  endemic  to  the  Amami  group,  and  the 
other  known  species  are  distributed  in  Formosa,  southern  China 
and  Cambodia.  This  group  of  species  is  known  under  the 
subgeneric  term  Trihelix  in  the  genus  Moellendorffia.^  Trihelix 
differs  from  the  typical  Moellendorffia  in  having  smooth  and 
shining  embryonic  whorls  and  in  the  aperture,  the  free  and  very 
peculiar  margin  of  the  parietal  wall  at  the  penultimate  whorl, 
which  bears  two  transverse  sulci  outside  of  the  last  part  of  the 
last  whorl  and  forming  two  tooth-like  folds  inside  of  the  aper- 
ture. However,  in  this  Japanese  species  the  peculiar  armature 
of  the  aperture  is  somewhat  reduced. 

The  general  features  of  the  genitalia  of  this  species  resemble 
rather  closely  those  of  the  Japanese  genera  Yakiichloritis  and 
Nipponochloritis,  but  distinctly  differ  in  the  short  but  thick 
receptaculum  seminis,  stout  penis  sheath,  the  very  short  flagel- 
lum  on  the  penis,  etc. 

Animal  long  and  narrow,  black  in  colour;  mantle  with  three 
black  bands  on  the  white  lung  area;  common  duct  (fig.  8,  c) 
very  long,  but  oviduct  (o)  short  (only  2.9  mm.)  and  thick  stalk 
of  the  receptaculum  seminis  (r)  comparatively  short,  the  length 
about  three  times  the  oviduct,  with  swollen  sac  on  the  distal  end ; 
vagina  (v)  swollen  towards  the  genital  pore  and  two  times  the 
length  of  the  oviduct;  vas  deferens  (d)  very  long  (nearly  17.9 
mm.)  ;  penis  (e)  10  mm.  long  Avith  finger-shaped  flagellum  (f), 
which  measures  only  0.8  mm.  in  length ;  insertion  of  penial  re- 
tractor near  basal  end  of  penis;  penis  sheath  (p)  thickish 
fusiform,  but  the  closer  part  of  the  genital  pore  is  narrowly  con-

LARGER  LAND  SNAILS  OF  SLEEPY  HOLLOW, 

KENTUCKY 

By  JAMES  E.  CONKIN 
Paleontologist,  Union  Producing  Co.,  Beeville,  Texas 

On  November  29,  1953,  in  the  course  of  investigating  the 
geology  and  paleontology  of  Sleepy  Hollow  (2.5  miles  north  of 
Worthington),  Oldham  County,  Kentucky,  I  collected  the  ''dead 
shells"  of  several  larger  land  snails  from  the  surface  of  the  hill 
slopes  at  Black  Bridge  on  the  south  fork  of  Harrods  Creek. 


July,    1957]  THE    NAUTILUS  11 

The  geology  and  paleontology  of  the  area  has  been  described 
(Conkin,  1948,  1950).  The  soil  is  formed  from  the  residuum 
of  the  Silurian  Louisville  limestone  and  Laurel  dolomite ;  the 
latter  forms  the  present  surface  outcrops  of  the  flat  uplands. 
On  the  valley  slopes  and  bottoms,  the  Ordovician  limestones  and 
shales  of  the  Richmond  group  (Waynesville,  Liberty,  and  White- 
water [Saluda]  formations)  are  exposed.  Calcareous  salts  are 
therefore  abundantly  distributed  in  the  soil  of  the  area  for 
use  by  the  snails  in  building  their  shells.  The  bushy  and 
forested  slopes  and  creek  bottoms  provide  excellent  habitats  for 
the  mollusks  of  the  area. 

Because  no  work  has  been  published  on  the  snails  of  the  area, 
and  very  little  on  Kentucky  snails  as  a  whole,  the  recording  of 
even  my  cursory  examination  of  the  snails  of  Sleepy  Hollow 
seems  worthy  of  notice.  Perhaps  this  note  will  engender  indi- 
vidual or  group  study  on  the  part  of  the  local  natural  history 
students,  or  at  least  prompt  collection  of  mollusks  and  their  do- 
nation to  workers  interested  in  pursuing  molluscan  studies  in 
the  region. 

A  list  of  larger  land  snails  from  Sleepy  Hollow  follows: 

Anguispira  kochi  (Pfeiffer) 

Haplotrema  concavum  (Say) 

Mesodon  elevatus  (Say) 

Mesodon  iiiflectus  (Say) 

Mesodon  thyroidus  (Say) 

Stenotrema  stenotrema  (Pfeiffer) 

Triodopsis  alholahris  (Say) 

Triodopsis  fraudulenta  (Pilsbry) 

With  the  exception  of  a  few  duplicate  shells  retained  by  the 
writer,  all  specimens  collected  at  Sleepy  Hollow  were  deposited 
in  the  mollusk  collection  of  the  Natural  History  Museum  at  the 
University  of  Kansas.

12  THE    NAUTILUS  [Vol.    71     (1) 

THE  MOLLUSCA  OF  TETON  COUNTY,  WYOMING 

By    DOROTHY    E.    BEETLE 

Teton  County,  in  northwestern  Wyoming,  has  an  area  of 
2,815  square  miles,  and  is  somewhat  larger  than  the  State  of 
Delaware.  Most  of  the  land  is  in  the  Teton  National  Forest, 
the  Tanghee  National  Forest,  the  Grand  Teton  National  Park, 
and  the  National  Elk  Refuge.  There  are  a  few  towns  and 
ranches  with  an  approximate  population  of  3,000. 

The  Teton  Range  runs  in  a  north  south  direction  for  over 
forty  miles  down  the  western  half  of  the  county.  One  of  the 
most  precipitous  mountain  fronts  in  the  world,  it  came  into 
being  during  the  Tertiary  when  faulting  along  a  north  south 
fracture  lifted  the  west  block  over  7,000  feet  and  tilted  it  west- 
ward. The  chain  of  high  peaks  so  formed  culminates  in  the 
Grand  Teton,  elevation  13,776  feet.  The  east  block  was  de- 
pressed, and  formed  the  valley  of  Jackson  Hole. 

Stretched  along  the  eastern  base  of  the  mountains  are  seven 
piedmont  lakes.  These  lakes  came  into  being  as  glaciers, 
hemmed  in  by  moraines,  melted  back  during  the  Pleistocene. 
Jackson  Lake,  the  largest,  is  400  feet  deep.  String  Lake  is  only 
10  feet  deep. 

The  eastern  half  of  the  county  is  entirely  mountainous,  con- 
taining the  Gros  Ventre  Range,  Pyramid  Peak,  Darwin  Peak, 
Sheep  Mountain,  Mt.  Leidy,  and  the  high  ridges  of  the  Conti- 
nental Divide.  The  northern  boundary  of  the  county  is  over- 
laid by  lava  flows,  a  continuation  of  the  volcanic  cover  of  Yellow- 
stone Plateau. 

Jackson  Hole  is  encompassed  by  these  highlands.  It  is  cen- 
trally located,  and  is  approximately  forty-eight  miles  long  and 
six  to  eight  miles  wide.  The  Valley  floor  is  comparatively  flat, 
covered  with  cobbles  left  by  the  glaciers  and  occupied  now  by 
sage-brush,  grasses  and  herbs.  It  is  drained  by  the  Snake  River 
and  the  many  streams  flowing  into  the  Snake  from  the  surround- 
ing mountains.  With  the  exception  of  minor  areas  in  the 
northeast  and  northwest  corners  of  the  county,  all  waters  flow 
into  the  Snake,  which  turns  west  through  the  Grand  Canyon 
of  the  Snake  River  into  Idaho,  and  eventually  joins  the  Columbia 
River.  The  minimum  elevation  of  5,800  feet  is  recorded  near 
Iloback  in  the  Grand  Canyon  of  the  Snake. 


July,    1957]  THE   NAUTILUS  13 

The  average  annual  precipitation  is  21.5  inches,  more  than 
that  received  by  any  other  county  in  Wyoming.  It  is  dis- 
tributed rather  evenly  throughout  the  year  as  snow  or  rain. 
Snow  has  occurred  every  month  of  the  year. 

The  monthly  mean  temperature  varies  from  13.6  to  61.3  de- 
grees Fahrenheit.  The  summers  are  cool  and  short,  with  an 
average  growing  period  of  sixty  days  in  the  valley.  The  short- 
est growing  season  recorded  at  Moran  since  1911,  when  weather 
records  were  initiated,  was  four  days.  The  longest  was  112 
days.  Temperatures  in  winter  may  descend  to  —  40  and  —  50 
degrees  P.,  with  a  minimum  temperature  recorded  in  the  valley 
of  —  63  degrees  F.  The  low  temperatures,  short  frost-free 
periods  and  the  deep  snows  are  critical  factors  in  the  develop- 
ment of  a  molluscan  fauna. 

The  soils  of  Teton  County  have  not  been  described  in  detail. 
In  general,  the  Teton  Range  and  the  Continental  Divide  in  the 
northeastern  corner  have  acid  mountain  soils  lying  on  granite 
or  ryolite.  The  mountains  in  the  eastern  section  have  a  granitic 
core  overlain  by  sandstones  and  limestones.  The  soil  is  a  brown 
sandy  loam.  In  the  north,  the  volcanic  cover  has  a  mixture  of 
acid  mountain,  sandy  loam,  and  some  limey  valley  soils.  The 
central  valley  of  Jackson  Hole  shows  limey  valley  soils  over- 
lying recent  terrace,  bench  and  bottom  deposits. 

Four  life  zones  are  recognized,  the  Transition,  Canadian, 
Hudsonian  and  Arctic- Alpine.

Prior  to  1956,  the  locality,  Moran,  refers  to  the  town  at  the 
foot  of  Jackson  Lake  Dam.  This  town  is  being  relocated  farther 
north  on  Highway  87-287. 

Aspen  groves  provided  the  most  favorable  habitat  for  ter- 
restial  snails.  The  groves  are  of  limited  extent,  occurring  as 
narrow  bands  or  clumps  around  a  valley  between  the  sagebrush 
and  grass  below  and  the  coniferous  forest  above,  or  in  openings 
in  the  forest.  Furthermore,  the  groves  must  be  divided  into  two 
ecotypes.  According  to  Dr.  John  F.  Reed,  in  a  paper  on  the 
vegetation  of  Jackson  Hole  Wildlife  Park,  two  distinct  types  of 
aspen  community  occur  there,  and  this  seems  true  of  the  rest 
of  the  county. 

The  aspen  groves  adjacent  to  meadows  or  water  or  in  an 
opening  in  the  coniferous  forest  are  characterized  by  closed 
canopies,  moist  subsoil,  and  a  lush  undergrowth  of  shrubs,  herbs 
and  grasses.  Dr.  Reed  has  identified  seventy-eight  species  of 
vascular  plants  in  this  assemblage.  Twenty-five  species  of  ter- 
restial  gastropods  occur  under  these  conditions. 

Stands  on  arid  slopes  are  usually  very  dry,  especially  in  mid- 
summer and  early  fall.  The  exposure  is  generally  toward  the 
south,  and  the  drainage  is  rapid.  Only  thirty-eight  species  of 
vascular  plants  have  been  found  within  these  groves.  Oreohelix 
suhrudis,  Vallonia  cyclophorella,  Vitrina  alaskana,  and  a  broken 
shell  of  Pupilla  were  seen.  The  first  two  speciies  are  also  to  be 
seen  under  similarly  xeric  conditions  in  the  sagebrush  and 
under  talus  of  sedimentary  rock. 

An  aspen  grove  on  a  morainal  deposit  at  Signal  Mountain 
Pond  yielded  sixteen  species  of  gastropods,  the  greatest  number 
seen  in  any  particular  grove.  Almost  all  these  species  could  be 
found  under  the  bark  and  debris  beneath  any  decaying  aspen 
log.  The  animals  were  scattered  apparently  at  random,  seem- 
ingly without  competition  for  food  or  space.  In  the  leaf  litter 
between  logs,  only  Oreohelix  siihrudis  and  Discus  cronkhitei  were 
encountered.  As  should  be  borne  in  mind,  1954  and  1955  oc- 
curred in  a  period  of  dry  years. 

Spruce  fir  forests  lie  in  moist  pockets  of  the  mountain  ranges. 


20  THE    NAUTILUS  [Vol.    71     (1) 

usually  on  the  north  slopes.  In  this  community,  mollusks  are 
generally  confined  to  seeps,  moist  protected  areas,  and  the  banks 
of  mountain  rivulets,  preferably  where  shrubs  and  an  occasional 
hardwood  tree  grow.  Sixteen  species  were  identified  from  this 
assemblage.  The  river  bottoms,  with  an  edging  of  cottonwoods 
and  an  undergrowth  of  willow  and  grasses  also  yielded  sixteen 
species.  Snails  were  scattered  widely  through  the  leaf  litter, 
debris,  in  the  grass  and  even  under  cobblestones  piled  in  the 
dry  section  of  the  river  beds.  This  habitat  is  probably  less  mesic 
than  might  appear,  as  the  cottonwoods  form  an  open  canopy. 

In  places  along  the  rivers  and  lakes  and  in  wet  meadows, 
dense  thickets  of  willow  form  a  growth  approximately  ten  feet 
high.  In  the  thick  piles  of  moldering  leaves,  ten  species  of 
mollusks  live. 

Lodgepole  pine  forest  and  the  sagebrush  communities  occupy 
the  largest  areas  in  the  county.  While  only  two  species  were 
found  in  the  sagebrush,  ten  species  were  found  in  the  lodgepole, 
these  in  limited  quantities.  The  dense  young  stands  of  lodge- 
pole admit  almost  no  understory  of  plants  and  no  snails. 
Mature  forests  are  dry  and  open  with  a  more  abundant  under- 
story. Snails  were  most  likely  to  be  located  under  decaying 
logs,  particularly  hardwoods,  and  not  in  the  pine  duff. 

Grassy  areas  along  ditches  and  in  meadows  yielded  eight 
species.  These  usually  lived  under  stones  and  old  logs  in  the 
area.  Exceptions  were  Oxyloma  decampi  gouldi  w^hich  crawls 
about  on  the  rushes  and  grasses  in  damp  places,  and  Oreohelix 
suhrudis  which  is  to  be  found  at  the  base  of  plants  in  the  scant 
protection  afforded.  Six  species  were  found  in  small  patches 
of  Sphagnum  bog.  Here  the  mollusks  w^re  crawling  through 
the  moss. 

Under  the  rather  arid  conditions  that  prevail  in  Wyoming, 
moisture  appears  to  be  the  limiting  factor  in  the  distribution  of 
terrestial  gastropods.  United  States  Weather  Bureau  Statistics 
(1950)  of  the  annual  average  precipitation  within  the  twenty- 
three  counties  range  from  6.47  to  20.77  inches.  Other  conditions 
being  equal,  hardwoods,  particularly  aspen,  provide  a  preferred 
habitat.  Limestone  or  sedimentary  rocks  offer  a  more  favor- 
able substratum  than  granitic  rocks. 

Thirty-four  species  of  terrestrial  mollusca  were  identified,  the 
most  common  being  Zonitoides  arhoreus,  Discus  cronkhitei,  Oreo-

helix  suhrudis,  Vitrina  alaskana,  and  Euconulus  fulvus  var. 
alaskensis. 

Aquatic  habitats  with  a  mud  or  silt  bottom  seemed  to  provide 
a  more  favorable  location  for  fluvial  species  than  did  gravel  or 
sand  bottoms.  The  latter  conditions  may  be  a  reflection  of  the 
swifter  currents,  leaving  behind  bare  creek  bed  with  a  minimum 
of  vegetation  to  provide  food  and  shelter.  Only  live  mollusks 
were  counted  as  being  present  at  any  station,  although  dead  ones 
washed  down  from  other  localities  were  often  present.  Thirty- 
nine  species  were  collected,  the  most  common  being  Pisidium 
casertanum,  Lymnaea  palustris  and  var.  Wyoming ensis,  Gyraulus 
vermicularis  and  Physa  gyrina. 

Field  work  for  this  report  was  carried  out  during  a  week's 
stay  in  August  of  1954  and  1955  at  the  Jackson  Hole  Biological 
Research  Station. 

The  author  wishes  to  thank  Dr.  Alan  A.  Beetle  for  specimens 
he  and  his  students  have  collected  in  the  course  of  his  studies 
at  Jackson  Hole.  Mr.  Ernest  Roscoe,  Dr.  Herbert  and  Lorna 
Levi,  Dr.  Wendell  Gregg  and  Dr.  George  Baxter  have  con- 
tributed material  for  identification  and  examination  from  their 
collections.  Some  of  Dr.  Junius  Henderson's  material  in  the 
University  of  Colorado  was  examined.  Reverend  H.  B.  Herr- 
ington  identified  the  Sphaeriidae,  and  Mr.  Roscoe  identified  the 
Oreohelix.

By  DOROTHEA  S.  FRANZEN 

Illinois  Wesleyan  University 

In  1920  the  Wisconsin  Geological  and  Natural  History  Survey 
induced  Dr.  Frank  C.  Baker  to  study  and  prepare  a  report  of 
the  fresh  water  Mollusca  of  Wisconsin.  His  studies  of  that 
fauna  resulted  in  his  describing  numerous  species  and  sub- 
species. Many  of  those  holotypes  and  paratypes  are  deposited 
in  the  Museum  of  The  Wisconsin  Geological  and  Natural  History 
Survey,  University  of  Wisconsin.     Because  there  has  been  no 

1  Expenses  incurred  in  travel  necessary  to  prepare  this  list  have  been 
covered  by  Grant-in-Aid  of  the  Illinois  State  Academy  of  Science.

listing  of  such,  types,  I  have  prepared  the  following  list.  The 
procedure  has  been  that  followed  in  the  preparation  of  Part  I 
of  this  series.  Dr.  Baker  used  the  term  type  to  designate  the 
holotype,  therefore,  that  term  is  used  here  and  also  as  a  means 
to  conserve  space  as  suggested  by  the  editor.

GUY   L.   WILKINS:   AN   APPRECIATION 

By  JOSEPH  EWAN 

Guy  Lawrence  Wilkins,  conchologist,  artist,  bibliophile,  was 
little  known  personally  to  Americans  because  he  did  not  visit  the 
New  World.  For  those  of  us  who  in  recent  years  have  visited 
the  British  Museum  (Natural  History)  he  will  be  long  and 
affectionately  remembered.  I  went  to  England  in  1954,  not  as 
a  conchologist,  but  as  a  botanist  in  search  of  letters,  notebooks, 
and  archive  materials  bearing  on  the  history  of  natural  history. 
I  was  introduced  to  Mr.  Wilkins  at  the  'Canteen,'  the  social 
institution  of  the  Museum  where  morning  coffee,  lunches,  and 
teas  are  served  to  the  staff  and  the  public.  Our  British  friends 
waggishly  remark  of  this  as  one  more  break  through  of  the 
Americanization  process  since  the  last  war.  The  staff  and 
visitors  drop  in  for  tea,  a  smoke,  a  chat,  to  discuss,  to  plan,  to 
dissect,  and  for  a  few,  to  swap  secondhand  booksellers'  cata- 
logues. It  was  perhaps  in  this  last  connection  that  I  first 
'found'  Mr.  Wilkins.  To  emend  the  motto  on  the  library's 
facade,  "books  constrain  none,"  except  the  bookcollector  !  Vari- 
orum editions,  states,  and  half  morocco  are  collector's  language, 
and  o.p.  are  his  middle  initials.  And  Guy  Wilkins  was  an  avid 
collector  of  natural  history  titles,  and  of  malacological  books 
in  particular.  He  loved  fine  books  in  fine  bindings,  and  owned 
many. 

"I  have  had  a  few  more  books  which  are  getting  increasingly 
expensive  and  hard  to  get,"  he  wrote  me  last  July.  "The  re- 
print of  Linne's  12th  ed.  Syst.  Nat.  (3  vols.)  is  the  latest  acquisi- 


36  THE   NAUTILUS  [Vol.    71    (1) 

tion,  very  desirable  but  will  have  to  be  rebound,  I  fear.  The 
British  Museum  (Nat.  Hist.)  Catalogue  (8  vols.)  fills  a  corner 
of  my  small  room  but  very  welcome — I  managed  to  get  a  set  just 
before  they  ran  out  of  stock  and  put  the  price  up  for  what  is 
left.  Another  nice  little  thing  was  the  history  of  the  Orkneys 
(Wallace,  1700)  with  a  good  list  of  the  plants  also  shells.  It 
is  in  excellent  condition  (neatly  repaired)  but  cost  me  £2.  Ah 
me !  Why  am  I  so  tempted  by  these  ancient  things  ?  My  best 
treasure  recently  was  a  priced  copy  of  the  Portland  Catalogue 
(1786)  complete  with  a  portrait  of  the  Duchess,  most  unusual  to 
get  that  and  the  annotations  were  by  Francillon,  the  goldsmith 
and  entomologist." 

Wilkins  knew  the  London  libraries  intimately,  and  made  ex- 
tensive use  of  books  and  their  marginalia,  increment  of  past 
owners,  in  the  preparation  of  his  bibliographic  papers.  He  pos- 
sessed a  detailed  knowledge  of  explorers  and  expeditions.  He 
was  an  effective  worker,  modest  and  imaginative.  To  his  co- 
workers at  the  Museum,  he  was  friendly  and  good-humoured. 
To  those  who  came  to  the  Museum  with  shells  to  name,  he  was 
warm  and  sympathetic. 

Born  November  5,  1905,  at  Stoke,  Lewington,  London,  Mr. 
Wilkins  started  his  working  life  as  a  commercial  artist,  and 
joined  the  British  Museum  in  1949.  His  skills  acquired  during 
his  years  as  a  commercial  artist  carried  over  to  his  professional 
career,  and  it  is  likely  that  the  confining  habits  and  close  long 
hours  of  the  drawing  board  impaired  his  health.  He  entered 
the  hospital  December,  1956,  with  granular  eruptive  tuberculosis 
and  died  March  6th,  in  his  fifty-second  year.  He  had  recentlj^ 
modelled  an  exquisite  series  of  marine  invertebrates  for  a 
Scottish  museum  using  newer  techniques  and  colored  by  hand. 

Best  known  to  the  conchologist  are  his  historical  studies  on 
the  Sir  Hans  Sloane  (1953)  and  Sir  Joseph  Banks  (1955)  shell 
collections  at  the  British  Museum,  published  in  the  recently 
inaugurated  Bulletin  of  the  Museum's  Historical  Scries.  His 
earlier  paper  on  Sloan's  shells  in  the  Journal  of  Conchology 
(1952),  and  his  latest  paper,  "Notes  on  the  'Historia  Con- 
chyliorum'  of  Martin  Lister  (1683-1712),"  with  a  portrait,  pub- 
lished in  the  Journal  of  the  Society  for  the  Bihliography  of  Nat- 
ural History  (1957)  will  continue  to  be  consulted.  A  third 
historical  Bulletin  on  the  shell  collection  of  Rev.  Clayton  Mor- 


THE    NAUTILUS  Ul 

daunt  Cracherode,  1730-1799,  trustee  of  the  British  Museum, 
and  antiquarian,  is  in  press.  For  each  of  the  historical  studies 
already  published  he  sketched  a  portrait  as  a  cover  medallion. 
Wilkins'  attention  to  handwriting  and  to  the  interpretation  of 
symbols  (e.g.  ''N.  H. "  for  New  Holland,  or  present  New  South 
Wales,  when  it  appears  on  an  occasional  shell)  will  enhance  the 
value  of  his  work  for  future  students. 

For  me  it  shall  be  Guy  Wilkins  among  his  books,  both  of  us 
listening  to  Alice,  his  charming  wife,  play  the  harpsichord,  in 
their  hearthside  on  Hampstead  Heath — a  precious  memory.

DREDGING  FOR   DEEP  WATER  SHELLS   IN 
SOUTHERN  FLORIDA 

By  PAUL  L.  and  THOMAS  L.  McGINTY 

A  growing  interest  in  deep-sea  shells,  particularly  in  Florida, 
has  encouraged  the  writers  to  record  a  few  observations  and  notes 
concerning  results  obtained  after  five  years  of  operation,  and 
some  2000  dredging  stations  from  aboard  the  cabin-cruiser 
''Triton."* 

These  explorations  were  made  by  Arthur  R.  Thompson,  to- 
gether with  the  authors,  from  a  31  foot  motor-vessel  equipped 
with  power  winch  holding  5000  feet  of  steel  cable,  and  a  swing- 
ing davit  with  block  and  tackle  for  bringing  in  the  heavy  dredges 
and  trawls.  Considerable  dredging  was  done  along  the  lower 
Florida  east  coast  from  Jupiter  southward  to  the  Miami  region, 
and  from  various  points  along  the  Keys  as  far  west  as  the  Dry 
Tortugas.  Greatest  concentration  was  made  at  three  points, 
namely:  Palm  Beach,  representing  the  lower  mainland;  Som- 
brero Key,  the  middle  Keys;  and  Key  West,  the  lower  Keys; 
all  at  depths  ranging  from  10  to  more  than  150  fathoms.  Be- 
cause of  a  marked  dissimilarity  between  conditions  along  the 
Keys  and  off  the  lower  east  coast,  both  as  to  shell  life  and  type 
of  bottom,  we  thought  best  to  comment  upon  each  region  sepa- 
rately. 

Dredging  Off  the  Palm  Beach  Area 

Between  Miami  and  Palm  Beach,  where  the  Gulf  Stream  makes 
its  closest  approach  to  the  mainland,  the  100  fathom  line  runs 
only  about  4  miles  off  shore,  then  gradually  turns  outward  in 
progression  up  the  coast.  With  this  factor  in  mind,  most  of 
our  dredgings  were  made  between  the  Palm  Beach  Inlet  south- 
ward to  a  point  beyond  Delray  Beach,  approximately  25  miles,

and  perhaps  half  that  distance  northward  into  the  Jupiter  area. 
Deep  water  close  to  shore  provided  a  reasonable  means  of  retreat 
in  the  event  of  sudden  violent  squalls,  and  permitted  much  saving 
of  time  in  reaching  and  returning  from  the  deeper  dredging 
stations.  It  also  enabled  prominent  shore  bearings  to  remain 
visible,  even  in  deep  water,  so  that  carefully  taken  compass 
bearings  with  subsequent  triangulation  upon  marine  charts  made 
possible  determination  of  depth  and  position  with  a  considerable 
degree  of  accuracy.  The  latter,  of  vital  importance  in  supplying 
accurate  scientific  habitat  data  for  each  dredge  haul,  also  pro- 
vided means  for  returning  to  the  same  area  should  the  dredge 
contain  exceptional  material.  As  every  experienced  fisherman 
knows  of  certain  ' '  holes ' '  where  the  fishing  is  usually  good,  so 
will  the  dredger,  through  experience,  learn  of  certain  areas 
where  the  shell  life  is  more  abundant,  or  upon  which  the  rarer, 
more  desirable,  species  may  appear.  In  the  process,  one  also 
learns  to  avoid  certain  types  of  bottom  which,  for  reasons  not 
fully  known,  may  contain  an  abundance  of  long  dead  shells,  but 
be  practically  devoid  of  life  at  the  moment. 

Progressing  sea-ward  from  the  beach  the  yellowish  rather 
coarse  sand  (low  in  coral  content  since  sizable  corals  are  rare 
throughout  the  area,  but  largely  composed  of  silica  and  finely 
broken  shell)  continued  more  or  less  unchanged  until  the  reef 
was  attained  in  approximately  15  fathoms,  perhaps  a  mile  off 
shore.  This  scattered  rocky  reef,  rather  poorly  defined  in  depth 
and  continuity,  may  be  entirely  lacking  in  some  areas,  but  else- 
where continue  outward  to  40  fathoms  or  more.  To  the  dredger, 
little  of  importance  appeared,  save  littoral  forms,  until  a  depth 
of  20  to  40  fathoms  over  a  ''live"  portion  of  this  reef  was  ap- 
proached where  a  most  interesting  and  extremely  variable  mol- 
luscan  life  seemed  to  occur.  With  luck,  from  such  a  station,  an 
incredible  assortment  of  sea-life  might  be  brought  up  in  the 
dredge,  ranging  from  many  types  of  sea-weed  to  sponges  of 
weird  shape,  from  gorgonians  to  strangely  shaped  crabs  and 
lovely  brittle-stars,  all  brilliantly  colored  and  seeming  to  cover 
the  spectrum  in  the  wildest  sort  of  array.  Even  the  mollusks 
appeared  to  follow  the  pattern,  with  orange,  yellow  and  red 
far  commoner  than  might  be  expected.  A  rather  spiny  form  of 
Turho  castaneus,  beautifully  shaded  with  various  hues  of  rose, 
and  the  lovely  and  rare  Conus  juliae,  in  red,  were  typical  ex-

amples  of  the  colorful  shells  which  might  be  taken,  on  occasion, 
from  this  reef.  Here  also  lived  the  vari-colored  Pecten  henedicti, 
Mitra  liendersoni  and  M.  moisei,  the  rare  Primovula  carnea  and 
several  recently  described  species  of  Calliostoma.  Oddly, 
Scaphella  jitnonia,  not  too  uncommon  along  the  v^est  coast  of 
Florida,  proved  to  be  extremely  rare,  although  it  did  live  upon 
this  reef.  An  interesting  race  of  small  but  apparently  adult 
Xenopliora  conchyliophora  also  was  noted,  the  shells  profusely 
covering  themselves  by  attaching  small  irregularly  shaped  stones, 
but  strangely  never  attaining  the  larger  size  of  specimens  found 
in  shallower  water.  From  sand  pockets  between  scattered  por- 
tions of  the  reef  came  delicate  Feci  en  chazaliei  {tereinus),  to- 
gether with  Corhula  disparilis,  a  weirdly  shaped  little  bivalve 
resembling  nothing  so  much  as  a  miniature  box  with  tight  fitting 
lid.  Also  brought  up  were  a  number  of  species  which  appear 
to  be  new  northern  records  for  the  east  coast  of  Florida,  namely : 
Casmaria  atlantica,  Turbo  canaliculatus,  Tenagodus  squamatus 
and  Latirus  infundihulum. 

Of  course,  after  handling  tons  of  this  reef  material,  the 
reader  must  appreciate  that  here,  as  elsewhere  in  this  paper, 
space  permits  mentioning  but  a  few  of  the  species  which  were 
actually  found.  The  reef,  unfortunately,  is  a  most  difficult 
territory  to  work,  and  great  care  must  be  used  to  avoid  loss  of 
dredge  and  cable  should  the  equipment  become  snagged  in  the 
rocks  below.  This  was  particularly  so  because,  vdth  the  Gulf 
Stream  nearby,  there  was  generally  a  rather  strong  current  flow- 
ing northward.  Frequently  the  dredge  would  surface  so  heavily 
filled  with  reddish  rocks  and  material  to  be  sorted  that  a  davit 
was  almost  essential  for  hoisting  the  load  into  the  boat.  Be- 
cause of  many  irritants  to  the  hands,  such  as  sponge  spicules, 
urchin  spines,  stinging  corals  and  hydroids,  plus  various  types 
of  anemones,  heavy  canvas  gloves  were  used  while  handling 
any  large  quantity  of  this  material. 

Toward  the  outer  edge  of  this  rocky  reef,  in  about  40  to  50 
fathoms,  the  bottom  contained  more  broken  shell  together  with 
smaller  detached  rocks  or  rubble,  gradually  changing  from  sand 
to  mud.  The  curious  little  Ancistro syrinx  radiata,  resembling  a 
tiny  oriental  pagoda,  lived  in  this  softer  bottom,  as  did  Fusinus 
eucosminus  and  Terehra  floridana. 

Moving  outward  to  a  range  of  50  to  60  fathoms  over  isolated 


40  THE    NAUTILUS  [Vol.    71    (2) 

rubble  patches  in  quite  muddy  bottom,  one  might  hope  to  bring 
up  a  specimen  of  Mitra  antillensis,  perhaps  the  largest  and  rarest 
of  the  West  Indian  miters.  Conus  stimpsoni,  a  pretty  yellow 
species  might  be  taken  at  this  depth ;  also  Fusinus  timessus  and 
Antillophos  heaui,  both  being  new  northern  east  coast  records. 
Generally  speaking  however,  unless  some  rocky  rubble  was  pres- 
ent, dredging  in  this  soft  grey  mud  proved  somewhat  disappoint- 
ing, for  at  times  the  dredge  would  surface  almost  empty  save 
for  a  few  chunks  of  burned  material  resembling  clinkers,  a 
possible  residue  from  ancient  coal-burning  ships  which  at  one 
time  used  this  still  well  traveled  south-bound  steamer  lane. 

At  an  average  depth  of  75  fathoms,  the  desirable  areas  of 
broken  shell  and  rubble  became  even  scarcer,  never  the  less  cer- 
tain patches  harbored  an  amazing  array  of  extremely  choice 
shells,  but  unfortunately  no  great  abundance.  Among  the  prizes 
taken  were :  Pecten  phrygium  and  glyptus;  Liomesus  stimpsoni; 
Cuspidaria  rostrata,  the  largest  east  coast  form  of  this  peculiar 
bivalve ;  Xenophora  longleyi,  an  interesting  deeper  water  carrier- 
shell  which  freely  but  insecurely  attaches  stones  and  broken  shells 
while  young,  later  losing  most  of  them  to  become  almost  ' '  nude ' ' 
at  maturity ;  Murex  heaui,  largely  young,  but  one  unique  colony 
of  beautiful  yellow-brown  adults  was  discovered;  Conus  mcgintyi 
(formerly  mazei),  a  lovely  slender  cone,  very  rare,  its  radula 
highly  transparent  and  extremely  small,  the  species  lacking 
operculum ;  and  Mitra  fluviimaris,  an  attractive  and  rare  white 
miter  recently  named  to  honor  the  Gulf  Stream.  Species  col- 
lected which  appear  to  establish  new  northern  records  for  the 
east  coast  include  XenopJiora  caribaeum,  Conns  villejyini,  Cymat- 
ium  occidentale  and  rehderi,  Murex  heaui  and  Bursa  corrugata; 
all  found  between  70  and  80  fathoms  in  muddy  bottom  containing 
some  rubble. 

Further  off  shore,  in  soft  mud  at  80  to  90  fathoms,  a  lovely 
volute,  Aurinia  georgiana,  was  obtained.  At  times  these  shells 
came  up  in  the  dredge  with  one  or  more  specimens  of  a  pale 
and  strangely  unattractive  deep-sea  anemone  firmly  attached 
to  cover  most  of  the  upper  portion  of  the  shell.  Seemingly  hard 
pressed  for  points  of  attachment,  these  creatures  chose  with  equal 
facility  any  bits  of  stone,  clinkers  or  other  debris  which  might  be 
exposed  along  the  bottom.  Volutes  living  in  this  soft  mud 
tended  to  produce  a  heavy  dark  epidermis  as  protection  from 


October,  1957]  the  nautilus  41 

the  etching  acids  of  these  unwelcome  visitors,  while  those  from 
bottom  with  a  higher  sand  content,  free  from  anemones,  usually 
had  a  thin  and  transparent  periostracum.  Anatomical  observa- 
tions indicated  that  the  male  of  Aurinia  georgiana  is  consider- 
ably more  slender  and  smaller  than  the  female.  At  the  same 
depth,  in  patches  of  slightly  firmer  bottom,  we  were  thrilled  to 
locate  a  few  colonies  of  Calliostoma  psyche,  an  exquisite  cream 
colored  shell  spotted  with  rose,  and  having  that  peculiarly  lovely 
iridescence  found  on  only  a  few  deep-water  shells. 

Mud,  at  105  fathoms,  afforded  optimum  conditions  for  still 
another  volute,  Clenchina  robust  a.  This  species  seemed  to  be  a 
special  attraction  for  deep-sea  anemones,  for  we  noted  instances 
where  these  creatures  had  almost  closed  the  shell  aperture  to 
cause  severe  distortion  of  the  moUusk's  growth.  As  in  C. 
georgiana,  these  volutes  tended  to  form  a  heavy  rough  protective 
periostracum  in  badly  infested  areas,  but  even  so,  severe  erosion 
could  be  detected  on  some  living  specimens  brought  to  the  sur- 
face. Fortunately,  at  a  few  localities  we  found  the  anemones 
less  abundant,  and  the  shells,  with  a  thinner  epidermis,  came  up 
in  perfect  condition. 

Attempts  to  dredge  at  150  fathoms  or  more  were  somewhat 
disappointing.  Very  rarely  a  specimen  of  the  striped  volute, 
Clenchina  gouldiana,  or  an  even  rarer  related  form  (always 
very  small,  cream  colored  without  bands  or  spots)  might  appear 
in  the  dredge  or  trawl.  Generally  speaking  however,  this  soft 
mud  off  the  Palm  Beach  area,  devoid  of  rocks,  offered  little 
reward  with  the  exception  of  a  few  weird  deep-sea  crustaceans 
and  star-fish  plus  some  small  to  microscopic  shell  material  which, 
because  of  its  depth,  proved  of  considerable  interest. 

Dredging  Off  The  Florida  Keys 

Unlike  the  lower  east  coast  mainland,  an  outer  coral  and 
rock  reef  runs  more  or  less  parallel  and  perhaps  5  miles  to  the 
seaward  of  the  low  westward  curving  chain  of  islands  known  as 
the  Florida  Keys.  Extending  for  many  miles,  it  forms  a  most 
serious  danger  to  ships  and  has  long  been  marked  by  a  series 
of  tall  lighthouses  strategically  located  along  its  length.  This 
reef,  submerged  for  the  greater  portion,  may  be  thought  of  as 
replacing  the  beach  off  the  mainland,  and  outward  distances  for 
the  dredger  are  most  conveniently  measured  by  using  it  as  a 


42  THE    NAUTILUS  [Vol.    71     (2) 

startinp:  point.  Between  the  reef  and  the  string  of  Kej^s  lies 
a  long  narrow  body  of  water  called  the  Hawk  Channel,  its 
depth  of  but  a  few  fathoms  affording  good  passage  for  yachts 
and  smaller  vessels  only.  Looking  seaward  from  the  reef,  the 
100  fathom  line  extends  slightly  further  off  shore  than  along 
the  mainland,  approximately  5  miles,  so  the  total  run  from  one 
of  the  Keys  to  attain  this  depth  becomes  10  miles  instead  of  the 
4  miles  noted  off  the  Palm  Beach  coast.  Besides  a  considerable 
loss  of  time,  this  additional  mileage  creates  somewhat  more  of  a 
weather  hazard  since  the  deeper  dredging  must  all  be  done  well 
beyond  sight  of  land,  and  sudden  storms  in  these  open  Gulf 
Stream  waters  become  most  unpleasant  for  small  boats.  Regu- 
lar checks  upon  the  weather,  both  by  radio  and  personal  observa- 
tion, are  certainly  well  advised.  Unfortunately  the  exact  loca- 
tion of  position  becomes  increasingly  more  difficult  at  the  greater 
depths,  since  visual  bearings  become  available  only  wdthin  range 
of  one  of  the  important  lighthouses.  Luckily  these  ranges  are 
considerable,  however,  since  some  of  the  lights  are  designed  to 
remain  visible  up  to  18  miles  at  sea. 

To  the  conchologist,  perhaps  the  most  interesting  factor  con- 
cerning dredging  in  this  region  lies  in  the  presence  of  an  ex- 
tensive more  or  less  flat  rocky  area  knowm  as  Pourtales  Plateau. 
Actuall}^  patches  of  whitish  sand  and  grey  mud  would  seem  to 
indicate  that  its  surface,  at  least,  is  not  composed  entirely  of 
exposed  rock,  and  while  usually  considered  to  begin  at  about  90 
fathoms  and  extend  outward  for  a  considerable  distance,  its 
exact  contour  w^ould  appear  to  vary  somewhat  since  we  detected 
its  presence  in  isolated  areas  as  shallow  as  65  to  70  fathoms,  off 
both  Sombrero  Key  and  Key  West.  As  might  be  expected,  the 
presence  of  rocks  in  the  deeper  water  affords  an  environment  so 
contrasting  with  the  soft  bottom  off  the  Palm  Beach  area,  at  a 
similar  depth,  that  a  number  of  species  of  mollusks  are  confined 
to  one  of  these  areas  alone.  Inside  the  rocky  plateau,  a  much 
larger  proportion  of  species  proved  common  to  both  regions, 
with  depth  ranges  of  most  species  being  almost  identical.  This 
Pourtales  Plateau,  while  certainly  most  interesting  to  w^ork, 
should  hardly  be  thought  of  as  a  grab-bag  for  the  eager  dredger 
however,  for  material  may  be  obtained  only  with  considerable 
difficulty.  The  rocky  terrain  is  extremely  hard  on  dredges,  with 
trawls  being  practically  out  of  the  question,  and  while  we  found 
the  Gulf  Stream  current  somewhat  less  than  that  usually  experi-

enced  off  Palm  Beach,  it  was  sufficient,  at  times,  to  cause  our 
cable  to  twang  like  a  plucked  banjo  string.  For  some  reason 
ancient  dead  shells  far  outnumbered  living  ones,  but  w^hether 
this  indicates  a  decline  of  life  upon  the  plateau  or  is  a  natural 
process  we  hesitate  to  speculate,  although  this  preponderance 
of  dead  material  was  far  less  evident  in  our  dredgings  off  the 
east  coast. 

In  order  that  our  report  of  dredging  off  the  Keys  may  be 
consistent  and  follow  the  pattern  already  established  in  our 
discussion  of  findings  off  Palm  Beach,  let  us  now  return  to 
shallow  water  inshore  and  gradually  work  outward  towards 
deeper  water  and  the  Pourtales  Plateau.  First  we  might  say 
that  dredging  in  the  shallow  water  of  the  Hawk  Channel,  with 
its  eelgrass  and  numerous  bars  and  patches  of  heavy  coral 
growth,  proved  none  too  productive  and  we  believe  other  methods 
of  collecting  serve  better  for  working  this  area. 

A  short  distance  outside  the  reef  which  separates  Hawk 
Channel  from  the  open  sea  the  bottom  gradually  became  a  soft 
sticky  white  marl  supporting  vast  beds  of  eelgrass  and  occasional 
isolated  patches  of  rubble.  On  these  limited  areas  of  harder 
bottom,  the  molluscan  life  seemed  more  abundant,  and  from 
about  20  to  40  fathoms,  over  such  a  station,  specimens  of  the 
attractive  Conus  sozoni  were  obtained.  Sconsia  striata  also  was 
taken  from  this  depth  but  proved  to  be  quite  rare,  apparently 
preferring  an  area  further  westward  in  the  Gulf  of  Mexico  where 
it  is  somewhat  more  abundant. 

A  depth  of  40  fathoms,  over  rubble  bottom  when  it  could 
be  located,  appeared  to  be  a  favorable  habitat  for  a  rather  wide 
range  of  interesting  and  somewhat  uncommon  species.  From 
here  we  brought  up  fine  living  specimens  of  Antigona  strigillina, 
a  lovely  white  bivalve  slightly  over  an  inch  in  diameter  and 
rather  a  rare  shell  in  collections.  Also  found  were  Chama 
lactuca,  the  delicately  fragile  Pecten  chazaliei  (tereinus),  and 
Aeqiiipecten  lineolaris,  the  latter  a  rarity  and  apparently  new 
northern  record  for  this  species.  Among  the  gastropods  repre- 
sented were  the  greatly  elongated  Torcula  exoleta,  its  near  white 
shell  almost  perfectly  matching  the  bottom  color,  and  an  ex- 
tremely lovely  little  rock-shell  known  as  Murex  tryoni.  Another 
collector's  treasure,  Murex  cahriti,  was  taken  occasionally,  with 
a  small  colony  of  unusually  attractive  orange  colored  specimens 


44  THE    NAUTILUS  [Vol.    71    (2) 

luckily  discovered  in  the  vicinity  of  Sombrero  Key.  Other  dis- 
coveries included  Conus  austini,  apparently  a  new  northern 
record,  and  Fusiniis  timessus  and  F.  exicosmius,  the  latter  shell 
seeming  to  suggest  deep  water  and  rarity,  and  almost  exclusively 
confined  to  areas  of  heavy  rubble  or  broken  rocks. 

From  a  depth  of  40  to  50  fathoms  the  pretty  orange-yellow 
Conus  stimpsoni  made  an  appearance,  together  with  the  curiously 
distorted  Distorsio  mcgintyi,  while  at  60  fathoms  Pecten 
phrygiuni  was  present.  Strangely,  from  one  isolated  rubble 
reef  not  far  from  Sombrero  Key  we  dredged  a  lovely  large  yellow 
specimen  of  this  rare  Pecten,  while  a  second  pass  over  the  same 
territory  brought  up  a  smaller  specimen  almost  orange  in  color. 
Previously  we  had  never  seen  this  species  except  in  its  normal 
coloration  of  mottled  rose  and  are  at  a  loss  to  explain  such  an 
unusual  variation,  but  it  serves  admirably  to  demonstrate  the 
value  of  accurately  determined  position  and  the  resulting  ability 
to  return  as  close  as  possible  to  an  exact  area  of  unusual  interest. 

Apparently  a  great  rarity  in  the  volute  family,  Aurinia 
schmitti  was  taken  in  mud  at  depths  from  60  to  80  fathoms,  but 
unfortunately  in  very  limited  numbers  and  seldom  in  perfect 
condition.  As  is  of  interest  to  note,  these  shells  do  not  always 
have  the  heavy  glazing  which  was  thought  to  be  characteristic 
of  the  species.  Possibly  due  to  differing  bottom  conditions,  we 
found  a  few  specimens  which  were  quite  clean  and  free  from  any 
glazing  whatever.  Perhaps  one  of  our  greatest  treasures,  a 
perfect  %  inch  adult  of  the  extremely  rare  Haliotis  poiirtalesi, 
came  from  a  rocky  reef  in  only  65  fathoms  off  Sand  Key,  near 
Key  West.  Another  prize,  taken  in  70  fathoms  off  Key  West, 
was  a  damaged  but  reasonably  fresh  specimen  of  Pleurotomaria 
quoyana,  apparently  the  first  record  of  this  extremely  rare  deep- 
sea  ''slit  shell"  having  been  taken  in  waters  bordering  the 
United  States.  After  rather  extensive  explorations  in  the  Key 
West  area,  we  finally  succeeded  in  locating  a  colony  of  the  rare 
Murex  nuttingi  living  on  a  limited  portion  of  rubble  reef  at  a 
depth  of  75  fathoms.  At  approximately  the  same  depth,  but 
more  widely  distributed,  Bartschia  significans,  a  rarity  appearing 
in  few  collections,  made  an  occasional  appearance  in  our  dredge 
hauls.  Also  at  75  fathoms  we  were  fortunately  able  to  bring 
up  a  few  specimens  of  the  exquisitely  lovely  giant  deep-sea 
Epitonium,  Sthenorytis  pernohilis,   its  lacy  white   contrasting 


October,  1957]  the  nautilus  45 

strikingly  with  a  large  jet  black  operculum.  Our  finest  speci- 
men, 42  mm.  long,  still  living  and  with  operculum  intact,  came 
up  in  the  dredge  in  perfect  condition,  and  was  so  conspicuous  in 
appearance  that  its  presence  was  detected  even  before  the  dredge 
was  brought  on  board.  Certainly  of  all  the  thrills  we  have 
enjoyed  in  dredging  for  shells,  this  must  come  very  near  the 
top  of  the  list.  Another  great  thrill  was  presented  when  we 
brought  up  a  lovely  specimen  of  Murex  heaui  complete  with 
' '  fronds  and  frills, ' '  from  off  Sombrero  Key  in  75  fathoms.  Al- 
though most  collectors  visualize  heaui  as  always  possessing  the 
overly  developed  varices  of  the  often  figured  unique  specimen 
belonging  to  the  National  Museum,  this  is  hardly  so.  At  all 
localities  from  which  we  took  heaui,  and  we  took  a  respectable 
series  from  a  number  of  areas,  we  found  the  "wide  fronded" 
variety  to  be  extremely  rare.  Although  there  is  a  greater 
tendency  towards  emphasis  of  the  fronding  in  young  specimens, 
we  took  but  one  adult  which  possessed  this  characteristic,  and  it 
came  up  in  a  dredge  haul  containing  another  specimen  which 
entirely  lacked  this  peculiarity.  As  a  result  of  our  observations, 
we  feel  strongly  convinced  that  the  wide  varix  is  far  from  being 
a  specific  character  and  should  not  be  treated  as  such. 

Conus  villepini,  a  strikingly  marked  rare  white  cone,  some- 
what elongated  and  irregularly  blotched  with  brown,  was  rather 
closely  confined  to  depths  from  75  to  80  fathoms,  while  two  at- 
tractive rock-living  volutes,  Clenchina  dohrni  and  Clenchina 
florida,  ranged  from  about  75  to  100  fathoms  along  the  Pourtales 
Plateau.  As  is  of  interest  to  note,  neither  of  these  volutes  was 
found  in  the  Palm  Beach  area,  perhaps  due  to  scarcity  of  rocks 
in  deeper  water  off  the  east  coast.  Likewise,  Aurinia  georgiana, 
found  in  soft  mud  off  Palm  Beach,  failed  to  appear  in  the  Keys 
area,  although  a  possible  counterpart,  Aurinia  schmitti,  might 
be  considered  to  replace  it  in  the  softer  bottom  off  the  Keys. 

Aurinia  duhia,  originally  described  and  figured  by  Broderip 
in  1827  from  a  shell  without  locality,  continued  to  remain  a 
puzzle.  His  figure,  showing  a  large  bulbous  protoconch  and  two 
weak  plications  on  the  columella,  it  is  not  quite  like  any  volute 
yet  seen  by  the  authors  from  Gulf  of  Mexico  or  Florida  waters. 
The  early  date  of  publication  rather  suggests  that  the  original 
specimen  might  have  been  taken  in  a  fish-trap  from  one  of  the 
Lesser  Antilles,  but  until  the  original  type  specimen  is  eventually 


46  THE    NAUTILUS  [Vol.    71     (2) 

found  and  examined  it  would  seem  that  the  exact  identity  of 
duhia  must  continue  to  remain  an  interesting  mystery. 

In  white  sand,  at  about  90  to  100  fathoms,  Microgaza  rotella 
was  taken  on  occasion,  providing  the  smaller  mesh  dredges  were 
used,  for  this  species,  in  its  attractive  golden  iridescence,  does  not 
attain  large  size. 

Bursa  tenuisculpta,  although  rare,  was  taken  living  at  115 
fathoms  and  appeared  to  be  confined  to  the  deeper  water  along 
the  Pourtales  Plateau.  The  deep-water  carrier  shells,  Xenophora 
carihaeum  and  X.  longleyi,  had  a  much  wider  depth  range,  speci- 
mens having  been  taken  as  shallow  as  70  fathoms  and  extending 
out  to  the  greatest  depths  which  we  attained. 

In  deep  water,  from  sandy  areas  between  the  rocks,  a  wide 
variety  of  interesting  pelagic  species  were  taken,  including  that 
transparent  jewel,  Cavolina  tridentata,  largest  of  the  deep-water 
flying  snails,  and  the  curious  Herse  columnella,  resembling 
nothing  so  much  as  an  extremely  miniature  milk-bottle. 

In  addition  to  mollusks,  other  interesting  things  appeared  in 
our  dredges.  From  one  reef  off  Sombrero  Key,  in  100  fathoms  or 
more,  Ave  brought  up  pieces  of  a  strangely  beautiful  and  most 
delicate  coral  quite  unlike  anything  we  had  seen,  while  from 
the  same  reef  a  large  pale  whitish  sponge  was  obtained,  replete 
with  villainous  sharp  spicules  which  made  it  most  difficult  to 
handle.  One  trawl  came  up  so  packed  with  small  brittle-stars 
that  the  load  could  not  be  brought  on  board  until  a  part  of  the 
contents  had  been  dumped,  and  long  spined  urchins  also  made 
frequent  appearances  in  loads  from  the  deeper  water,  one  species, 
vividly  colored  in  red  and  yellow,  actually  being  quite  attractive. 
From  a  70  fathom  reef,  off  Key  West,  a  large  and  perfect  basket- 
star,  species  unknown  to  us,  made  a  rather  surprising  appearance. 

Because  of  space  limitations,  no  attempt  has  been  made  to 
mention  all  shells  obtained,  but  rather  an  effort  has  been  made  to 
name  those  species  which  we  feel  to  be  of  greatest  interest  to  col- 
lectors, together  with  depths  and  types  of  bottom  upon  which  they 
were  found.  Although  there  were  exceptions  which  tended  to 
range  over  a  considerable  area,  surprisingly  most  species  were 
quite  closely  restricted  to  the  depths  as  given  above.  Although  the 
*' Triton"  lacked  a  modern  electronic  depth  finder  and  we  were 
obliged  to  obtain  this  data  b}'  other  methods,  we  were  gratified 
to  learn,  upon  a  number  of  dredging  cruises  with  our  friend  the 


October,  1957]  the  nautilus  47 

late  Todd  L.  Moise,  where  the  writers  had  the  great  pleasure  of 
serving  as  invited  guests  and  guides  aboard  his  luxuriously 
equipped  motor-sailer  Escape,  that  our  measurements  agreed 
almost  to  the  fathom  with  those  indicated  by  an  elaborate  elec- 
tronic device. 

In  conclusion,  certainly  no  discussion  of  dredging  in  the 
Keys  area  would  be  complete  without  some  mention  of  the  limita- 
tions imposed  so  frequently  by  weather.  Although  the  region 
affords  delightful  cruising  for  small  boats  and  yachts,  the  open 
waters  of  the  Gulf  Stream  rapidly  become  quite  choppy  in  any- 
thing more  than  a  gentle  to  moderate  wind.  Unfortunately, 
dredging  from  a  small  boat  is  not  only  extremely  difficult,  but 
hazardous  as  well,  unless  the  seas  are  reasonably  calm.  Our 
practice  of  organizing  cruises  to  the  Keys  to  last  something  over 
a  month,  usually  in  June  or  July,  when  light  winds  might  rea- 
sonably be  anticipated,  worked  out  quite  well,  but  even  so,  we 
vividly  recall  one  period  of  a  full  ten  days  during  which  it  was 
too  rough  to  attempt  a  single  haul  with  the  dredge.  The  pleas- 
ures and  thrills  of  deep-sea  dredging  far  outweigh  the  disap- 
pointments however,  so  once  the  material  is  brought  home  and 
mounted  in  the  collection,  perhaps  the  many  difficulties  encoun- 
tered serve  some  useful  purpose  by  causing  us  to  appreciate 
even  more  those  delio^htful  treasures  from  so  far  beneath  the  sea. 


NOTES   ON  LAND   SNAILS  OF  GENERA 
SOLAROPSIS  AND  NENIA 

By  henry  a.  PILSBRY 

In  the  course  of  determining  specimens  of  Solaropsis  from 
Colombia,  I  had  occasion  to  look  over  the  species  of  Guiana. 
Finding  nomenclatural  irregularities,  I  was  led  to  investigate 
the  history  of  several  species  and  to  regulate  their  nomenclature.

Helix  constrictor  Hupe,  1853,  Eev.  et  Mag.  de  Zool.  (2  ser.),  5: 
p.  298. 

This  snail,  characterized  by  the  presence  of  two  deep  pits  on 
the  base,  has  long  been  known  as  Helix  or  Solaropsis  pellis- 
serpentis  Chemnitz,  1795.  Chemnitz's  nomenclature  was  not 
consistently  Linnean  and  is  not  now  admitted,  but  having  been 
accepted  by  Ferussac  and  Dr.  L.  Pfeiffer  this  name  passed  into 
general  use.  Chemnitz  had  used  the  same  name  in  1786  for 
what  is  now  regarded  as  another  species,  and  this  early  use 
was  the  basis  of  Helix  pellisserpentis  Gmelin,  1791.  Beck  in 
1837  recognized  that  two  forms  were  involved,  and  introduced  a 
varietal  name,  cicatricata,  for  Chemnitz's  snail  of  1795.  A  few 
years  later  H.  Hupe  saw  that  two  species  had  passed  under  the 
same  name  and  he  named  the  pitted  one  Helix  constrictor.  Sub- 
sequent authors  have  followed  Pfeiffer 's  incorrect  usage. 

This  species  is  variable  in  size,  diameter  41  to  53  mm.  in  ANSP. 
specimens,  but  I  have  seen  little  variation  in  the  development 
of  the  deep  pits  at  the  periphery  and  base,  though  their  position 
varies  from  directly  opposite  the  aperture  to  a  place  somewhat 
more  anterior. 

Dr.  F.  Haas  (Archiv  fiir  MoUuskenkunde  78:  152)  has  given 
Brazilian  localities  for  this  species  and  the  next,  under  their 
Pfeifferian  names.  The  type  locality  in  Guiana  was  fully  de- 
scribed by  Chemnitz.

Martyn 's  nomenclature  is  not  strictly  Linnean  so  that  his 
name  is  not  valid  as  of  1786,  and  apparently  must  give  way  to 
Helix  undata  Solander,  1786.

October,  1957]  the  nautilus  49 

Helix  coluhrina  Perry,  1811  (Conchology  pi.  15,  fig.  4)  was 
possibly  a  Solaropsis  undata,  but  the  figure  is  so  preposterously 
bad  that  no  certain  identification  is  possible. 

Solaropsis  pellis-hoae  Hupe  (Revue  de  Zoologie,  1853,  p.  299), 
is  a  large  species  apparently  closely  similar  to  S.  undata  (Sol.), 
but  I  have  not  seen  it.  The  locality,  Mission  de  Sarayacu,  Peru, 
is  a  hamlet  in  the  state  of  Loreto,  in  the  Rio  Ucayali  valley  near 
the  75th  meridian  at  about  6°58'  S.  lat. 

8.  U7idata  (Sol.)  has  the  subsutural  and  peripheral  spot  bands 
as  in  S.  cicatricata,  and  dense,  fine  granulation,  also  as  in  that 
species ;  but  the  last  whorl  is  regular,  without  pits.  A  specimen 
measures :  alt.  35  mm. ;  diameter  54  mm.,  5l^  whorls.  Figures 
were  given  in  Man.  Conch.  5,  pi.  58,  figs.  38,  39,  40. 

Solaropsis  anomala,  new  species.     PL  3,  Figs.  1,  la,  lb. 

The  rather  solid  shell  is  like  S.  undata  in  general  figure 
having  a  dome-shaped  spire  and  angular  periphery,  but  it  differs 
by  having  a  modified  last  whorl,  which  on  the  side  opposite  the 
aperture  is  swollen  below  the  suture,  and  in  the  peripheral 
region  it  is  impressed  and  concave  (fig.  la).  The  base  is  broadly 
concave  and  coarsely  striate  radially  around  the  umbilicus.  The 
first  21/2  whorls  are  smooth,  the  following  whorls  are  minutely, 
densely  granulose  on  the  upper  surface,  and  the  last  II/2  whorls 
have  some  coarse  striae  along  lines  of  growth.  The  color  pattern 
is  like  that  of  8.  cicatricata  and  8.  undata.  On  a  whitish  ground 
there  is  below  the  suture  a  broad  band  of  crescentic  to  angular 
reddish  brown  spots  alternating  with  white  ones ;  at  the  periph- 
ery there  is  a  band,  half  as  wide,  of  more  or  less  angular  smaller 
spots.  The  white  peristome  is  reflected  throughout,  and  is 
dilated  half  over  the  umbilicus. 

Height  32  mm.,  diameter  51  mm. ;  width  of  umbilicus  behind 
lip  3.5  mm. ;  fully  6  Avhorls. 

Guiana,  exact  locality  unknown.  Type  85147  ANSP.,  received 
from  the  Philadelphia  Commercial  Museum  in  1903. 

Besides  8.  cicatricata  there  are  two  other  described  species 
of  8olaropsis  having  an  indentation  of  the  last  whorl:  8.  mono- 
lacca  (Pfr.)  and  8.  vipera  (Pfr.).  8.  monolacca,  from  Surinam, 
differs  from  our  species  in  color  pattern.  It  is  described  and 
figured  as  '^braungelb,  mit  vielen  rothbraunen,  kaum  welligen, 
Striemen  gezeichnet, ' '  and  without  the  subsutural  and  peripheral 


50  THE    NAUTILUS  [Vol.    71    (2) 

spot  bands  of  S.  anomda  and  others  of  the  cicatricata  group. 
The  right  lip  margin  is  said  to  be  ''schmal  ausgebreitet, "  not  well 
reflexed  as  in  our  species.  A  comparison  of  the  descriptions  and 
figures  shows  various  other  differences. 

S.  viper  a  (Pfr.),  described  from  a  specimen  from  Brazil  in 
the  Cuming  collection,  is  a  smaller  (37  mm.  diameter)  species 
with  the  typical  cicatricata  color  pattern  and  only  a  quite  small 
sulcus  above  the  peripheral  angle.  The  base  is  banded  and 
less  concave  than  in  8.  anomala. 

A  specimen  before  me,  no.  202991  ANSP.  agrees  well  with  the 
account  of  S.  vipera  except  for  its  larger  size,  50.4  mm.  diameter, 
and  by  having  fewer  basal  spiral  lines  of  dark  dots.  It  is 
labelled  ''Brazil,"  but  is  from  an  old  collection,  origin  not 
traceable. 

Dr.  Vernhout  (1914,  p.  7)  listed  under  ''8.  pellisserpentis"  a 
'^  specimen  collected  by  Mr.  Voltz  .  .  .  which  has  the  peculiar 
pits  of  the  left  side  but  faintly  indicated. ' '  I  doubt  whether  this 
specimen  is  really  referable  to  S.  cicatricata,  which  has  deep  pits 
very  constant  in  a  large  number  seen  in  various  collections.  Dr. 
Vernhout 's  shell  may  possibly  be  the  snail  described  above  as 
;8^.  anomala. 

SOLAROPSIS  UNDATA  BROWNI,  HGW  SUbspecieS. 

The  color  pattern  and  minute  surface  sculpture  are  as  in  S. 
cicatricata  and  S.  undata,  but  the  shape  is  far  more  depressed 
than  8.  undata  and  the  periphery  is  much  more  strongly  though 
bluntly  angular.  It  does  not  have  the  conspicuous  pits  of  8. 
cicatricata.  Height  29  mm.,  diameter  54.6  mm. ;  width  of  um- 
bilicus behind  lip  4  mm. ;  5%  whorls. 

This  race  is  known  by  the  type,  1446  ANSP.,  a  specimen  from 
the  A.  D.  Brown  collection  labelled  ''Peru."  It  was  figured 
as  a  depressed  form  of  ^^>S^.  serpens  Martyn"  in  the  Manual  of 
Conchology  5,  pi.  59,  figs.  50,  51,  52. 

Various  forms  of  the  8.  gihhoni  complex  are  equally  depressed, 
but  they  do  not  have  the  minute  granulation  of  this  subspecies 
and  others  of  its  group.

Nenia  (Andinia)  barcrofti,  new  species.     PI.  3,  Figs.  4,  4a,  4b. 

The  cylindric  shell  tapers  in  the  upper  half  to  a  truncate 
summit  closed  by  a  strongly  convex  plug.  Color  white  through- 
out or  faint  brown  with  a  brown  line  at  the  suture.  The  whorls 
are  only  slightly  convex,  the  last  almost  straight  sided,  shortly 
free  in  front.  Sculpture  of  irregularly  waved  and  frequently 
anastomosing  riblets  which  have  a  slightly  retractive  axial  di- 
rection. In  adult  shells  the  ventral  side  becomes  worn  smooth. 
On  the  latter  part  of  the  last  whorl  the  riblets  are  strong  and 
more  regular,  are  often  brown,  and  vary  in  number  individually, 
as  in  figs.  4  and  4b. 

The  aperture  is  broadly  ovate,  narrowed  at  the  upper  left 
extremity,  white  within.  The  peristome  is  white,  thin  and 
broadly  expanded.  The  superior  lamella  is  marginal,  high  and 
thin,  concave  on  the  left  side,  continuous  with  the  very  short 
but  high  and  arcuate  spiral  lamella ;  a  short  low  branch  at  their 
junction.  The  inferior  lamella  is  strong,  convex.  The  sub- 
columellar  lamella  is  deeply  immersed  and  rather  strongly  de- 
veloped within.  The  principal  plica  is  short,  lateral  and  dorsal, 
and  is  visible  externally  as  a  brown  line.  The  lamella  is  weak 
and  short,  curving  anteriorly  from  near  the  inner  end  of  the 
principal  plica. 

The  clausilium  tapers  distally  to  a  blunt  point  on  the  columel- 
lar  side  of  the  oblique  end,  and  posteriorly  passes  gradually  into 
its  filament. 

Length  35.5  mm.,  diameter  7.3  mm. ;  6  whorls  remaining. 
Length  34.5  mm.,  diameter  7.5  mm. ;  51^  whorls  remaining.

This  fine  Nenia  is  named  for  Mr.  Frederick  J.  Barcroft. 
Through  his  planning,  introductions  and  material  assistance  dur- 
ing several  years,  considerable  additions  have  been  made  to  our 
series  of  South  American  mollusks. 

Nenia  karsteniana  (Dohrn)  and  N.  magistra  (Sowerby)  are 
large  species  from  near  Bogota,  both  resembling  N.  harcrofti 
in  being  truncate  and  with  the  peristome  expanded,  but  in  both 
of  them  the  sculpture  is  less  coarse  and  irregular  and  it  is  far 
more  oblique.  In  N.  harcrofti  the  riblets  are  coarser  and  more 
interrupted,  and  they  run  nearly  parallel  to  the  axis  of  the  shell. 
The  short  principal  plica,  visible  externally  through  the  shell,  is 
unlike  the  karsteniana  group. 


PRUNUM  ROSCIDUM  IN  NEW  JERSEY 

By  R.  tucker  ABBOTT 
Pilsbry  Chair  of  Malacology 

Mrs.  Clara  Burke  and  other  members  of  the  Philadelphia  Shell 
Club  have  been  finding  in  New  Jersey  living  examples  of  an  at- 
tractive marginellid  which  superficially  resembles  Prunum  gut- 
tatum  Dillwyn.  Closer  investigation  indicates  that  these  speci- 
mens are  Prunum  roscidum  (Redfield),  a  species  which  Conrad, 
Dall  and  others  have  erroneously  synonymized  under  the  Miocene 
species,  Prunum  limatulum  Conrad.  Below,  we  give  a  brief 
account  of  P.  roscidum  (see  pi.  4  figs.  4,  4a).

Outer  lip  thickened,  white,  finely  denticulate  on  its  inner  edge, 
and  bearing  along  the  rim  of  the  varix  four  reddish  brown  spots 
— a  small  one  at  the  very  top,  a  broad  one  at  the  center,  another 
broad  one  %  the  way  down,  and  a  small  one  at  the  very  base 
of  the  shell.  Upper  area  of  the  parietal  wall  may  bear  a  swollen, 
white  callus.  Columellar  teeth  white,  the  upper  two  short  and 
almost  at  right  angle  to  the  axis  of  the  shell,  the  lowest  two 
teeth  very  much  stronger  and  more  slanting.     Spire  short. 

Range :  Delaware  to  off  east  Florida.  Records :  Delaware :

leg.,  1940)  ;  27  fms.,  off  Miami  (T.  L.  Moise,  leg.  1954). 

Prunum  guttatum  Dillwyn,  a  southern  Florida  and  West 
Indian  species,  differs  in  having  five  varical  color  spots,  two  of 
which  are  at  the  base  of  the  shell  on  each  side  of  the  siphonal 
canal.  The  lower  two  columellar  teeth  are  shorter  and  weaker 
than  the  two  above ;  the  spire  is  much  lower  and  the  body  whorl 
more  gently  rounded.  P.  horealis  Verrill  1884,  found  in  deep 
water  from  Massachusetts  to  Virginia,  lacks  the  white  spottings, 
has  a  high,  pointed  spire,  and  has  very  weak,  if  not  absent, 
denticulations  on  the  inner  side  of  the  outer  lip.  P.  heali 
McGinty  is  a  smaller  (8  to  12  mm.  in  length),  rosier  form  or 
possibly  subspecies  of  roscidum  from  off  eastern  Florida,  where 
whittish  specimens  also  occur.  The  fossil  P.  limatulum  Conrad 
from  Virginia  appears  to  be  more  like  Verrill's  horealis,  and 
has  a  higher  spire  and  proportionately  broader  aspect  in  the 
upper  part  of  the  body  whorl.

length.  All  paratypes  similar  in  proportions  but  vary  in  size 
from  31  mm.  high  to  50.8  mm.  Left  valve  very  flat  and  pecu- 
liarly compressed  at  the  umbone.  Right  valve  convex.  Byssal 
notch  small  with  three  denticles  on  lower  margin.  Shell  white 
with  left  valve  maculated  with  brown  and  black.  Right  valve 
white.  Both  valves  yellow  at  the  umbones.  Hinge  line  straight 
and  stained  with  coffee-brown  on  interior.  Auricles  very  large 
and  equal.  Auricles  on  both  valves  are  radially  ribbed  with 
three  main  ribs  which  are  squamate.  Ribs  number  nine  or  ten 
and  are  rounded  with  the  tops  of  each,  on  both  valves,  covered 
with  crowded  scales  or  fimbriations  about  half  the  length  of  rib 
starting  at  the  outer  margin.  Sides  of  ribs  and  bottoms  of  inter- 
stices are  smooth.  Both  ribs  and  interstices  rounded  and  of 
practically  the  same  size. 

Holotype  and  several  paratypes  were  taken  at  Escape  Pass 
near  Cape  Leveque  in  N.  W.  Australia  from  tidewater  to  six 
fathoms.  Holotype  in  The  Academy  of  Natural  Sciences  of 
Philadelphia,  No.  225038. 

The  specimens  examined  were  taken  in  shallow  water  at  low 
tide.  Although  Murex,  Cypraea,  Conus  and  Mitra  were  also 
taken  the  only  other  Pecten  taken  near  the  locality  was  P. 
{Comptopallium)  radula  Linne.  P.  radula  is  narrow  and  elon- 
gate with  ten  to  fourteen  rounded  broad  ribs  with  radial  ribbing 
covering  them  and  fine  concentric  lines  crossing  them,  giving 
the  shell  a  granular  appearance.  It  has  no  scales  or  fimbriations 
and  the  left  valve  is  slightly  convex. 

Recently  some  shells  taken  at  the  Palau  Islands  have  many 
of  the  characteristics  of  this  new  variant.  However  the  Palau 
I.  shells  have  a  slight  curve  in  the  posterior  and  anterior  margins, 
the  left  valve  is  not  as  flat  and  the  scales  or  fimbriations  are 
not  as  pronounced.  These  slight  differences  may  be  entirely  due 
to  local  genetic  or  ecologic  variations. 

The  author  wishes  to  acknowledge  and  thank  Dr.  Harold 
Rehder  of  the  Nat.  Museum  in  Washington,  Dr.  Tucker  Abbott 
of  the  Academy  of  Nat.  Sciences  of  Philadelphia  and  Dr.  Leo 
G.  Hertlein  of  the  Cal.  Academy  of  Sciences  in  San  Francisco 
for  their  help  in  identifying  this  shell.

THE  RANGE  OF  THE  SEA  SCALLOP 

By  J.  A.  PosGAY 
U.  S.  Fish  and  Wildlife  Service,  Woods  Hole,  Mass. 

The  range  of  the  sea  scallop,  Placopecten  magellanicus 
(Gmelin),  has  been  variously  reported  to  be  from  Labrador  to 
New  Jersey  (Pratt,  1935;  Miner,  1950),  Newfoundland  to  New 
Jersey  (Morris,  1947),  and  Labrador  to  Cape  Hatteras  (Abbott, 
1955).  A  search  of  the  literature  and  major  museum  collections 
has  been  made  in  an  attempt  to  clear  up  this  confusion  among 
the  most  generally  available  manuals.  From  the  evidence 
gathered,  the  limits  seem  to  be  from  the  north  shore  of  the 
Gulf  of  St.  Lawrence  to  Cape  Hatteras. 

Since  the  sea  scallop  is  an  important  commercial  mollusk,  the 
United  States  and  Canada  maintain  records  of  the  location  and 
extent  of  their  sea  scallop  fisheries.  These  records  show  that  sea 
scallop  beds  of  sufficient  extent  and  density  to  support  a  fishery 
occur  from  Port  au  Port  Bay,  Newfoundland  (Latitude  48°  30' 
N)  to  the  Virginia  Capes  (Latitude  36°  50'  N).  The  animal 
probably  occurs  both  north  and  south  of  the  limits  of  the 
fishery. 

The  uttermost  limit  of  the  range  of  any  sedentary  marine 
animal  is  usually  a  vague  and  shifting  line.  A  specific  locality 
may  be  unsuitable  for  survival  in  most  years,  but  in  occasional 
years  the  environmental  stresses  may  be  reduced  to  the  point 
where  some  fraction  of  the  hardier  members  of  a  population  can 
survive  and  grow.  Therefore,  the  fringes  of  the  range  can  be 
expected  to  produce  only  a  thin  population  in  occasional  years. 

Whiteaves  (1901),  after  investigating  the  records  of  every 
major  expedition  which  had  collected  in  Eastern  Canada,  said 
that  the  most  northern  locality  in  which  the  sea  scallop  has  been 
dredged  was  Caribou  Island,  Province  of  Quebec.  His  reference 
is  Packard  (1867).  Caribou  Island  (Lat.  51°  25'  N,  Long.  57° 
39'  W)  is  well  inside  the  Gulf  of  St.  Lawrence.  No  more 
northerly  record  has  been  found  in  the  literature  which  has 
accumulated  since  Whiteaves'  time. 

The  only  evidence  that  I  have  found  to  support  the  idea  that 
the  sea  scallop  occurs  off  Labrador  is  one  shell  (No.  27271)  in 
the  mollusk  collection  of  the  United  States  National  Museum. 


56  THE    NAUTILUS  [Vol.    71     (2) 

It  is  labeled  "Caribou  Island,  Labrador"  and  cataloged  as  hav- 
ing been  received  from  Stimpson  in  1875  along  with  a  great 
many  other  shells.  There  is  no  mention  of  the  collector.  The 
most  probable  inference  is  that  these  shells  were  either  from 
Stimpson 's  private  specimen  collection  or  the  results  of  some 
dredging  expedition. 

Going  backward  in  time,  the  first  expeditions  which  might 
have  collected  the  shell  are  those  of  A.  S.  Packard  in  1860  and 
186-4.  He  dredged  from  Little  Mecatina  Island,  in  the  Gulf  of 
St.  Lawrence,  through  the  Straits  of  Belle  Isle  and  along  the 
Atlantic  coast  of  Labrador  as  far  north  as  Hopedale.  His 
dredging  locations  are  only  given  verbally  and  the  sea  scallop 
is  mentioned  as  being  found  off  Caribou  Island.  Whiteaves 
correctly  locates  this  in  Quebec.  Packard,  however,  calls  his 
paper  ''A  View  of  the  Invertebrate  Fauna  of  Labrador."  He 
also  acknowledges  that  he  is:  "indebted  to  .  .  .,  Dr.  William 
Stimpson,  .  .  .  for  valuable  aid  in  identifying  the  species  men- 
tioned below."  Stimpson  probably  was  given  his  choice  of  the 
duplicates,  labeled  the  sea  scallop  shell  ' '  Caribou  Island,  Labra- 
dor" and  pla'ced  it  in  his  private  collection.  Later,  he  presented 
part  or  all  of  his  collection,  including  the  sea  scallop  shell  with 
the  faulty  label,  to  the  United  States  National  Museum. 

Dredging  records  for  the  area  in  which  the  southern  limit  of 
the  range  might  be  expected  to  fall  are  scarce.  Chesnut  (1951), 
however,  says  that  fishermen  report  taking  sea  scallops  in  their 
nets  occasionally  while  trawling  off  Cape  Hatteras.  This  is 
about  as  far  south  as  they  would  be  expected  to  occur.  As  has 
been  shown  experimentally  (Posgay,  1953),  juvenile  sea  scallops 
cannot  survive  exposure  to  water  temperatures  above  23°  C; 
mature  specimens  are  killed  by  water  over  20°  C. 

The  average  20°  C.  bottom  isotherm,  at  its  most  northerly 
position,  leaves  the  shore  at  Cape  Hatteras  and  sweeps  gently 
northward  until  it  is  parallel  to  the  bottom  contours  at  about 
the  100  fathom  curve.  Probably  no  sea  scallops  would  be  found 
south  of  Cape  Hatteras  or  in  deep  water  off  the  North  Carolina 
coast.

PROPOSED  REVISION  OF  HALIOTIS  RUBER 

By  Egbert  K.  Talmadge 

In  the  course  of  a  systematic  and  comparative  study  of  the 
marine  family  Haliotidae,  some  interesting  information  came  to 
light  that  may  be  of  interest  to  malacologists.  The  literature 
covering  the  species,  that  was  once  known  as  Haliotis  naevosa 
Martyn,  1784,  was  a  bit  confusing.  There  were  several  names 
and  descriptions  covering  either  closely  allied  species,  or  races 
of  a  species  that  varied  from  locality  to  locality.  The  writer, 
after  an  intensive  study  of  this  group,  feels  that  a  single  species 
is  represented,  but  that  it  may  be  divided  into  three  geographical 
races.  This  proposed  revision  is  based  upon  the  following  in- 
formation. 

The  approach  to  the  problem  was  the  same  method  utilized  by 
ornithologists  in  their  monographic  works,  a  comparison  of 
populations  of  a  species.  Ino,  1951,  had  utilized  this  method  on 
his  work  with  the  discus-kamtschatkana  problem.  Talmadge, 
1956,  had  followed  this  method  in  the  discussion  of  the  Haliotis 
varia.  Others  had  found  this  method  satisfactory  in  working 
with  land  mollusks,  and  it  is  gradually  being  accepted  as  a  basic 
method  of  taxonomy.  By  this  kind  of  comparisons,  the  various 
age  stages,  ecological  populations,  and  pathological  specimens  are 
better  understood,  and  evaluated. 


58  THE    NAUTILUS  [Vol.    71     (2) 

Specimens  were  obtained  in  as  large  quantities  as  possible, 
with  accurate  locality  data.  Various  private,  university,  and 
museum  collections  were  utilized  as  well  as  the  writer's  personal 
collection.  Each  collecting  station  was  plotted  on  a  large  scale 
map,  with  pertinent  data  as  to  average  temperatures,  currents, 
and  the  basic  geology.  Soft  parts  were  obtained  and  studied  in 
conjunction  with  the  shells.  Research  libraries  were  used  in 
order  to  obtain  the  original  descriptions  and  illustrations.  After 
all  the  data  were  assembled  and  compared,  there  appeared  to  be 
a  natural  sequence  of  distribution  and  a  gradual  merging  of  one 
shell  type  into  another  with  similar  animal  parts.  This  is  one 
of  the  best  methods  in  working  with  the  haliotids;  as  has  been 
found  in  separation  of  the  species,  the  soft  parts  are  quite 
distinct. 

Apparently  in  the  southern  part  of  Australia,  a  warm  temper- 
ate region  (Macphearson),  or  the  Flindersian  of  Hedley  con- 
tained a  shell  that  was  rather  elongate,  high  spired,  with  strong 
lamellae.  This  sort  of  shell  merged  into  a  more  ovate,  lower 
spired  population  with  low  rounded  lamellae  as  one  entered  the 
cool  temperate  (Macphearson)  or  Peronian  (Hedley).  This 
kind  of  shell  in  turn  gradually  became  nearly  circular  with  a 
depressed  spire,  no  lamellae,  and  a  distinct  groove  below  the 
siphonal  angle  as  tropical  waters  were  reached  from  around  the 
Capricorn  Islands  or  the  Solandrian  Province.  With  this 
gradual  merging  of  shell  features,  the  animal  parts  remained 
the  same.  Juvenile  shells  were  identical  up  to  around  20  mm. 
major  diameter  and  could  not  be  separated.  A  search  of  litera- 
ture indicated  that  all  of  these  races  were  already  named,  but  due 
to  the  similarities,  there  appeared  to  be  some  confusion  as  to  the 
status.     The  following  names  are  presented  for  consideration. 

IIaliotis  ruber  ruber  Leach. 

H.  naevosa  Martyn,  1784,  Universal  Conchologist,  t.  34. 
H.  ruber  Leach,  1814,  Zool.  Misc.,  p.  54,  f.  23. 

This  is  the  ovate,  thin,  shell,  with  the  medium  spire  and  low 
rounded  lamellae.  The  range  covers  New  South  Wales,  Southern 
Queensland,  and  Eastern  Victoria.  Martyn  in  his  description 
gave  the  locality  as  New  South  Wales,  but  Leach  referred  only 
to  Nova  Hollandia.  If  Leach's  figured  specimen  was  typical, 
the  range  of  the  type  locality  would  be  from  around  Brisbane, 
Queensland  south  to  the  northern  portion  of  Victoria.     If  the

figured  specimen  was  not  typical,  the  range  could  be  extended 
north  to  the  Capricorn  Islands  and  south  to  around  Melbourne, 
Victoria. 

Specimens  from  around  Melbourne  in  the  south  are  not  typical 
in  comparison  with  the  more  northern  specimens,  but  seem  to 
be  intermediate  with  the  South  Australian  race.  By  the  same 
token,  Capricorn  Island  specimens  are  mixed  as  to  populations.

This  race  of  H.  ruber  is  rather  elongate,  thick,  high  spired, 
and  has  coarse  lamellae  crossing  the  shell.  The  animal  parts  are 
the  same  as  specimens  from  New  South  Wales  and  Victoria. 

Iredale  gave  the  type  locality  as  Port  Fairy,  Western  Victoria. 
Population  series  from  that  locality  westward  indicate  that  the 
Victoria  station  is  just  within  the  range  of  this  subspecies.  The 
exact  western  limits  of  the  range  are  unknown  to  the  writer,  but 
a  small  series  from  Cape  Esperence  indicate  that  the  race  ranges 
to  that  general  locality. 

Haliotis  ruber  clathrata  Reeve 

H.  clathrata,  Reeve,  1846,  Conch.  Icon.,  Vol.  Ill,  f .  72. 

In  the  tropical  waters  north  of  Australia,  there  is  a  small, 
nearly  circular,  depressed  race  of  H.  ruber,  that  has  a  depressed 
spire,  a  groove  below  the  siphonal  angle  and  lacks  the  cross 
lamellae  in  adult  shells.  Reeve  gave  Bohol,  in  the  Philippine 
Islands  as  his  type  locality.  Many  authors  have  referred 
clathrata  to  H.  ruber  as  a  juvenile.  As  mentioned  earlier,  juve- 
nile specimens  can  not  be  separated  in  their  early  stages.  Speci- 
mens from  Northern  Queensland  seem  to  fall  into  this  race,  as 
do  specimens  from  Thursday  Island,  northern  New  Caledonia, 
Indonesia,  and  Malaya.  In  some  lots  examined,  muscle  scars 
were  present  in  specimens  not  over  forty  millimeters  in  diameter. 
The  fact  that  muscle  scars  were  present  and  that  no  large  speci- 
mens have  been  found  in  this  tropical  area  as  far  as  known, 
indicates  that  this  northern  race  is  also  much  smaller  than  the 
ruber  s.s.  further  south.     In  a  population  series  from  the  Capri- 


60  THE    NAUTILUS  [Vol.    71     (2) 

corn  Islands,  the  small  round  race  is  indicated,  but  not  until 
Townsville,  Queensland  is  reached  does  the  race  become  separable 
enough  to  warrant  a  subspecific  name. 

The  writer  wishes  at  this  time  to  express  his  appreciation  to 
the  various  private  collectors,  museums,  and  universities  in 
Australia,  Indonesia,  Malaya,  and  the  United  States  for  fur- 
nishing material  and  field  information  pertaining  to  this  study. 
Thanks  are  also  given  to  Stanford  University  and  to  the  Cali- 
fornia Academy  of  Sciences  for  the  use  of  their  research  libraries.

ELLIPTIC   COMPLANATUS   ROANOKENSIS   IN  THE 

NEUSE  RIVER 

By  WALDEMAR  M.  WALTER  and  RICHARD  A.  PARKER 
Department  of  Zoology,  State  College  of  Washington,  Pullman,  Washington 

In  1950  and  1951  the  Neuse  River  Basin  in  North  Carolina 
was  studied  to  determine  the  mollusks  present  and  their  dis- 
tribution (Walter,  1956).  Among  those  collected  were  32  shells 
of  Elliptio  complanatus  roanokensis  (Lea,  1836). 

Empty  shells  of  E.  complanatus  roanokensis  were  taken  from 
six  Neuse  River  stations,  one  in  the  Coastal  Plain,  five  in  the 
Fall  Zone.  Three  of  the  latter  group  of  stations  yielded  live 
specimens.  Prior  to  their  collection  from  the  bedrock  of  the 
river  bottom,  they  were  seen  lying  on  their  sides  in  fast-flowing 
waters  from  two  to  five  feet  deep.  At  least  100  live  specimens 
were  readily  available,  but  most  were  left,  to  conserve  what 
appeared  to  be  a  locally  distributed,  small  population.  At  one 
of  the  three  stations  supporting  live  E.  complanatus  roanokensis, 
about  four  feet  of  fast,  turbid  water  prevented  visual  determina- 
tion of  their  attitude  before  removal.  However,  the  shells  were 
acquired  here  by  lightly  scraping  the  even,  firm  bottom  with  a 
scraper  net.  Since  almost  nothing  but  shells  was  brought  up, 
there  can  be  little  doubt  that  here,  too,  the  big  mussels  were 
lying  on  their  sides. 

Athearn  (1954)  reports  this  form  from  packed  sand  and 
gravel  in  fairly  rapid  current,  but  says  nothing  of  mussel  posi- 
tion relative  to  substrate ;  since  he   describes  the  substrate  as 


October,  1957]  the  nautilus  61 

packed,  a  partly  buried  position  seems  unlikely.  If  the  usual 
position  of  E.  complanatus  roanokensis  in  the  Neuse  River  is  also 
characteristic  of  other  drainages,  then  this  naiad  occupies  a  dis- 
tinctive habitat.  Other  Neuse  Basin  species  were  found  in  the 
usually  described  position  of  freshwater  mussels,  i.e.,  partly  em- 
bedded in  the  bottom  with  the  posterior  exposed. 

The  dorsal  muscle  scars  of  E.  complanatus  roanokensis,  as 
noted  by  Simpson  (1914),  form  a  row  extending  backwards 
through  the  beak  cavity  from  about  the  posterior  edge  of  the 
pseudocardinal  tooth,  whereas  the  dorsal  muscle  scars  of  Neuse 
Basin  E.  complanatus  occupy  only  a  small  depression. 

In  addition  to  the  differing  habitat  and  arrangement  of  the 
dorsal   muscle    scars,    there    is    a    conchometric    difference,    the

reality  of  which  was  tested  as  follows.  The  greatest  diameter, 
height  and  length  of  117  E.  complanatus,  and  32  E.  complanatus 
roanokensis  shells  were  measured  to  the  nearest  millimeter.  Mul- 
tiple regression  analyses  of  these  data  gave  an  objective  com- 
parison of  the  two  groups.  Excellent  simple  correlations  (r) 
exist  among  the  various  dimensions,  and  there  is  good  agreement 
between  the  estimated  slopes  (b)  of  the  bivariate  regressions 
(Table  I)  and  the  ratios  (D/H,  D/L,  H/L)  of  the  appropriate 
mean  values. 

Diameter  was  chosen  arbitrarily  as  the  dependent  variable. 
Since  some  error  was  inevitable  in  measuring  height  and  length, 
the  analytical  method  used  here  is  inexact;  however,  the  relia- 
bility of  the  results  obtained  seems  sufficient  to  validate  the  con- 


62  THE   NAUTILUS  [Vol.    71    (2) 

elusion  reached.     The  equations  arrived  at  for  E.  ccmiplanatics 
(1)  and  E.  complanatus  roanokensis  (2)  are: 

(1)  D  =  -  1.3  +  0.005L  +  0.621H 

(2)  D  =  -  1.3  +  0.147L  +  0.219H 

An  analysis  of  the  errors  of  estimate  from  a  common  regression 
plane  and  from  the  two  individual  regression  planes  shows  there 
is  a  highly  significant  difference  between  the  two  shell  forms 
(Table  II),  thus  substantiating  the  previously  noted  differences. 
The  data  so  far  presented  appear  adequate  to  permit  restora- 
tion of  the  specific  rank  given  the  form  roanokensis  by  Isaac  Lea.

However,  such  a  move  would  be  of  dubious  validity,  if  for  no 
other  reason  than  the  small  number  of  E.  complanatus  roanoken- 
sis shells  studied.  A  second  reason  for  feeling  so  is  that  six 
intergrades  had  the  shell  shape  and  proportions  of  E.  com- 
planatus, but  had  the  dorsal  muscle  scars  of  E.  complanatus 
roanokensis.  Finally,  seven  dead  shells  were  taken  from  a  pile 
of  dried  mud  on  the  base  of  a  midstream  bridge  support  in  the 
lower  Neuse,  four  of  which  were  E.  complanatus,  three,  E. 
complanatus  roanokensis. 

The  latter  three  specimens  were  noteworthy  in  two  ways. 
First,  they  were  among  the  smallest  encountered,  the  range  of 
diameter  being  13-21  mm.,  of  height,  28^6  mm.,  and  of  length, 
56-93  mm.     Second,  these  were  the  only  E.  complanatus  roano-

kensis  shells  seen,  alive  or  dead,  partly  buried  in  such  a  way 
as  to  make  it  appear  they  might  have  been  living  there  before 
exposure  and  killing  by  drouth.  Also  possibly,  of  course,  the 
entire  situation  at  the  bridge  was  an  artifact  of  flood,  of  animals, 
or  other  agency.  The  existence  of  these  three  and  of  two  others 
less  than  100  mm.  long  argues  against  the  possibility  that  the 
large  ones,  of  which  most  were  145-155  mm.  long,  are  a  gerontic 
variant  of  E.  complanatiis. 

A  question  raised  by  the  "bridge  shells"  is  that  of  the  habitat 
occupied  by  the  smaller,  younger  ones.  Where  do  they  occur? 
The  question  is  implicit  in  the  fact  that  the  only  living  specimens 
found  reclining  in  strong  currents  were  large  adults,  although 
two  empty  shells  less  than  100  mm.  long  were  found  in  such  a 
place. 

As  Ortmann  (1919)  and  Athearn  (1954)  have  concluded, 
E.  complanatus  roanokensis  may  prove  to  be  but  a  variety  of 
E.  complanatus  when  critically  studied  over  its  whole  range. 
But,  the  population  in  the  Neuse  River,  as  presently  known,  is  of 
subspecific  rank.

THE  TWENTY-THIRD  ANNUAL  MEETING  OF  THE 

AMERICAN  MALACOLOGICAL  UNION 

July  19-22,  1957 

When  each  annual  meeting  of  the  A.M.U.  becomes  history,  one 
is  tempted  to  describe  it  as  ''best  ever."  Without  dealing  in 
superlatives,  the  1957  meeting  at  Yale  University  was  well 
])lanne(l,  well  attended  and  well  conducted.  Only  the  1956 
meeting  betteri  d  the  registration  of  one  hundred  and  eleven, 
and  tlie  quality  of  the  scientific  papers  was  outstanding. 


October,  1957]  the  nautilus  67 

Mr.  Percy  A.  Morris  of  the  Peabody  Museum  was  the  official 
host,  aided  by  the  Connecticut  Shell  Club.  Visitors  were  housed 
in  freshmen  dormitories  on  the  old  campus  and  made  good  use  of 
the  facilities,  not  the  least  of  which  were  the  benches  beneath 
the  ancient  elms.  The  spirit  of  earlier  students  seemed  to  linger 
about  the  stately  old  college ;  indeed,  the  room  in  Connecticut 
Hall  set  aside  as  A.M.U.  headquarters  reputedly  was  the  bed- 
room of  Nathan  Hale.  Malacologists  too  have  left  their  mark 
at  Yale  University ;  here  Benjamin  Silliman  compiled  his  Journal 
which  ran  to  255  volumes  and  here  Charles  Montague  Cooke 
studied  under  Addison  E.  Verrill.  The  shell  collection  which 
they  began  is  now  cared  for  by  Percy  Morris  who  has  brought  it 
up  to  date  and  adds  to  it  as  the  occasion  affords. 

President  Ruth  D.  Turner  conducted  the  four-day  meeting; 
three  of  the  four  days  were  given  over  to  scientific  papers.  Some 
of  them  were  in  the  form  of  symposiums ;  one  on  medical  mala- 
cology was  led  by  Dr.  Edward  H.  Michelson,  another  which  re- 
ported on  research  work  in  a  U.  S.  Fisheries  Laboratory  was 
conducted  by  the  Director  of  the  laboratory.  Dr.  Victor  L. 
Loosanoff.  The  third  and  largest  on  the  subject  of  the  dis- 
tribution of  New  World  mollusca  and  conducted  by  Dr.  Thomas 
E.  Pulley  occupied  an  entire  afternoon.  Limited  time  curtailed 
most  of  these  interesting  papers  and  no  discussion  was  possible. 
In  all  probability  they  will  be  compiled  and  published  by  the 
A.M.U.  at  a  future  date. 

Kodachrome  slides  furnished  by  members  and  recalling  pre- 
vious meetings  were  shown  out-of-doors  on  a  balmy  evening, 
and  on  another  occasion  reports  of  the  activities  of  member 
clubs  were  made  by  members  who  happened  to  be  present.  The 
annual  dinner  was  highlighted  by  a  brief  talk  by  Dr.  Henry  A. 
Pilsbry  and  by  an  illustrated  accounting  by  Mr.  George  F.  Kline 
of  "Fielding  for  the  Pros." 

At  the  annual  business  meeting,  it  was  announced  that  A.M.U. 
membership  now  is  598,  an  all-time  high.  Miss  Ruth  E.  Coats, 
secretary  of  the  Pacific  Division,  was  present,  reported  a  most 
successful  meeting  of  that  group  at  Santa  Barbara  in  early  June. 
The  new  officers  of  the  A.M.U.  Pac.  Div.  are :  chairman,  Albert 
R.  Mead;  vice-chairman,  John  E.  Fitch;  secretary-treasurer, 
Ruth  E.  Coats. 

The  following  were  elected  to  serve  as  officers  for  1957-58  : 
president,  Aurele  LaRocque ;  vice-president,  R.  Tucker  Abbott ; 


68  THE   NAUTILUS  [Vol.    71    (2) 

2nd  vice-president,  Albert  R.  Mead;  secretary-treasurer,  Mar- 
garet S.  Teskey;  publications  editor,  George  M.  Moore;  council- 
lors-at-large,  Emery  P.  Chace,  Ralph  W.  Dexter,  Percy  A.  Morris, 
Katherine  v.  w.  Palmer. 

A  field  trip  to  the  U.  S.  Fisheries  Laboratory  at  Milford, 
Connecticut,  occupied  all  the  final  day.  Dr.  Victor  Loosanoff 
proved  an  able  host  and  his  guests  were  given  the  opportunity 
to  inspect  his  busy  laboratory  together  with  many  special  ex- 
hibits, then  were  taken  to  sea  aboard  the  two  laboratory  boats 
and  given  an  exhibition  of  dredging  on  several  types  of  bottom. 
The  very  enjoyable  day  was  a  fitting  end  to  the  1957  meeting 
of  the  American  Malacological  Union.  An  invitation  to  meet 
in  September,  1958  at  the  University  of  Michigan  at  Ann  Arbor 
has  been  accepted. — Margaret  C.  Teskey,  Secretary. 


WILLIAM  GILBERT  FARGO 
1867-1957 

As  already  noticed  in  the  pages  of  The  Nautilus  (vol.  70,  no. 
4,  p.  140),  Mr.  William  Gilbert  Fargo  passed  away  at  his  winter 
home  at  Pass-a-Grille  beach,  Florida,  on  Feb.  2nd,  1957,  at  the 
advanced  age  of  89.  A  civil  engineer  by  profession,  Mr.  Fargo 
had  maintained  a  life-long  interest  in  geology  and  natural  his- 
tory, especially  in  ornithology,  and  in  his  later  years  turning 
to  the  study  of  mollusks,  both  recent  and  fossil. 

Mr.  Fargo  was  born  in  the  city  of  Jackson,  Michigan,  on 
December  6,  1867,  the  only  son  of  William  II.  and  Nellie  (Gil- 
bert) Fargo.  After  two  years  of  high  school  where  he  studied 
some  mathematics,  physics  and  chemistry,  Mr.  Fargo,  now  18 
years  of  age,  obtained  his  first  employment  in  an  engineer  and 
survey  office  as  draftsman  and  field  assistant.  Here  he  learned 
to  run  a  Dumpy  level  and  transit.  Shortly  afterwards,  he 
opened  his  own  office  doing  land  and  drainage  surveying  and 
at  22  years  of  age  he  was  elected  county  surveyor  and  custodian 
of  records,  some  of  which  dated  back  to  1823-25,  and  in  1895 
published  a  detailed  property  map  of  the  city  based  on  original 
surveys.  Together  with  practical  experience  gained  in  the  field, 
he  completed  his  engineering  education  by  home  study  and  cor-

respondence  courses.  He  now  commenced  the  surveys  of  several 
river  basins  in  Michigan  for  the  purpose  of  locating  sites  for 
hydroelectric  dams,  the  first  of  these  leading  to  the  construction 
of  the  ''Trowbridge  Dam"  on  the  Kalamazoo  river  above 
Allegan.  In  1913,  together  with  four  other  associates,  he 
founded  the  Fargo  Engineering  company,  its  main  offices  located 
in  Jackson.  While  Mr.  Fargo  remained  active  in  the  company, 
that  is  through  1925,  61  hydroelectric  stations  had  been  designed 
and  constructed  partly  or  wholly  under  their  supervision  located 
in  29  states  of  the  union,  and  5  others  in  Canada  and  elsewhere. 
The  company  also  designed  and  erected  9  major  steam  plants  as 
well  as  many  miles  of  high  tension  transmission  lines.  The 
Fargo  company  was  also  a  pioneer  in  the  design  of  many  new 
types  of  dam  and  spillway  construction  which  since  have  become 
current  practice.  Of  the  many  plants  erected  during  this  period, 
all  are  still  in  full  operation  without  any  serious  failures  having 
occurred,  an  accomplishment  in  engineering  design  and  con- 
struction of  which  the  Fargo  company  can  be  justifiably  proud. 
From  an  early  date,  Mr.  Fargo  had  been  a  serious  and  ob- 
servant student  of  nature  which  was  no  doubt  fostered  and 
strengthened  by  his  contacts  with  the  great  out-of-doors,  as  he 
ran  his  surveys  or  pushed  his  canoe  up  and  down  the  many 
water-ways  of  Michigan  in  the  search  for  power-plant  sites.  In 
1925,  Mr.  Fargo,  then  at  the  age  of  55  years,  retired  from  active 
participation  in  company  operations  in  order  the  better  to  devote 
his  attention  to  natural  history  studies.  He  now  began  to  spend 
longer  periods  at  his  winter  home  at  Pass-a-Grille  on  Boca  Ciega 
Bay  near  the  entrance  to  Tampa  Bay.  Besides  geology,  mineral- 
ogy and  botany,  birds  had  also  been  a  major  interest  since  his 
boyhood  and  he  now  plunged  into  their  study  and  the  collecting 
of  scientific  skins  with  increased  vigor.  Mr.  Fargo 's  accomplish- 
ments in  ornithology  are  too  extensive  to  be  recorded  here.  At 
the  time  of  his  arrival  in  Florida  in  the  early  1920ths,  Pass-a- 
Grille  was  a  part  of  a  vast  expanse  of  sandy  beaches  which 
stretched  northward  to  Indian  Rocks  and  beyond.  As  reported 
by  Mr.  Frederick  Gaige,  formerly  of  the  University  of  Michigan, 
who  often  accompanied  Fargo  on  his  bird  trips,  here  was  a  large 
area  of  salt  grass  marshland,  the  habitat  of  the  seaside  and  sharp 
tailed  sparrows  as  well  as  a  patch  of  mangrove  which  harbored  a 
fine  colony  of  the  yellow  crowned  night  heron.     Here  also,  Mr. 


70  THE    NAUTILUS  [Vol.    71     (2) 

Fargo  collected  the  first  specimens  of  the  grooved  bill  ani  to  be 
recorded  from  Florida.  Outside  of  Florida,  Mr.  Fargo  collected 
in  upper  Michigan  and  made  several  lengthy  canoe  trips  in 
Canada  between  1921  and  1928,  covering  principally  the  region 
between  the  Great  Lakes  and  James  Bay.  In  addition  to  his  own 
collecting,  he  also  financed  several  major  expeditions  to  Texas, 
Mexico  and  the  southwest  under  the  auspices  of  the  Museum 
of  Zoology  of  the  University  of  Michigan,  principally  for  the 
purpose  of  bird  study.  An  expedition  to  Panama,  and  two  to 
the  Great  Bend  region  and  the  Chisos  Mountains  of  Texas  were 
especially  fruitful.  He  also  purchased  the  L.  Whitney  Watkins 
collection  consisting  principally  of  Michigan  bird  skins  as  well 
as  providing  the  funds  for  the  purchase  of  thousands  of  bird 
skins  from  Paraguay,  Guatemala,  Mexico,  Canada  and  elsewhere, 
which  all  w^ere  presented  to  the  Museum  of  Zoology  at  the  Uni- 
versity of  Michigan.  In  1927,  the  regents  of  the  University 
appointed  him  to  the  position  of  Honorary  Curator  of  Birds,  a 
title  which  was  changed  in  1943  at  his  request  to  that  of  Honor- 
ary Curator  of  Paleozoology  in  the  Museum  of  Paleontology  and 
Zoology.  He  was  a  member  of  the  Wilson  Ornithological  Club 
and  of  the  American  Ornithological  Union  besides  several  others. 
He  accumulated  a  very  large  library  on  American  birds  which  he 
donated  finally  to  the  Jackson  County  Audubon  Society.  For  a 
space  of  30  years  or  more,  he  was  a  close  friend  of  the  late  Dr. 
Josselyn  Van  Tyne,  curator  of  birds  at  the  Museum  of  Zoology 
of  the  University  of  Michigan,  also  of  Mr.  Frederick  Gaige, 
formerly  Director  of  the  same  institution.  He  was  instrumental 
in  having  set  aside  a  bird  refuge,  ''the  Palmer  Bird  Haven," 
a  53  acre  tract  on  Sandstone  creek  near  the  city  of  Jackson, 
Michigan. 

As  he  spent  so  much  of  his  time  at  Pass-a-Grille  on  the  west 
coast  of  Florida  where  shells  are  common,  it  was  but  natural 
that  Mr.  Fargo  would  become  interested  in  conchology.  Also 
according  to  information  furnished  by  Mr.  Gaige,  his  interest 
in  shells  may  also  have  been  further  stimulated  by  his  aquaint- 
ance  with  Joe  Lee,  a  retired  British  soldier  who  had  a  small 
shack  on  Long  Key  and  who  helped  to  eke  out  his  meager  pension 
through  the  sale  of  marine  curios  to  tourists  and  visitors.  On 
many  a  trip,  they  traversed  the  beach  together  for  shells,  es- 
pecially after  a  heavy  blow,  or  collected  at  low  tide  at  night  with

a  gasoline  lantern.  In  1938,  the  locality  for  Pliocene  or  Caloosa- 
hatchee  shells  was  discovered  by  Mr.  A.  P.  Cales  in  the  northern 
suburbs  of  Saint  Petersburg  which  thenceforth  was  to  receive 
much  of  Mr.  Fargo 's  intensive  method  of  research.  In  1940,  Mr. 
Charles  R.  Locklin  of  Saint  Petersburg  and  Pontiac,  Michigan, 
joined  in  this  work,  several  tons  of  marl  was  dug  up,  washed, 
screened  and  picked  over,  resulting  in  the  assembling  of  a  very 
large  collection  of  finely  preserved  fossil  shells,  particularly  rich 
in  the  smaller,  less  kno^vn  species.  In  addition,  Mr.  Locklin  ex- 
panded his  collecting  activities  to  other  Caloosahatchee  localities 
so  that  in  the  working  up  of  the  Saint  Petersburg  fauna,  good 
material  from  the  type  area  of  the  formation  would  also  be 
available  for  direct  comparison.  Although  Fargo  and  Locklin 
had  already  made  preliminary  identification  of  much  of  the 
Saint  Petersburg  collections,  the  entire  lot  with  the  exception 
of  the  Turridae  was  submitted  to  the  Academy  of  Natural  Sci- 
ences of  Philadelphia  for  further  study  and  a  final  writeup  which 
culminated  in  the  publication  of  a  special  volume  entitled  "The 
Pliocene  of  Southern  Florida"  and  issued  as  Number  8  of  the 
Monographic  Series  under  the  joint  authorship  of  Olsson,  Harbi- 
son, Fargo  and  Pilsbry.  In  the  course  of  the  Saint  Petersburg 
collecting,  Mr.  Fargo  had  become  interested  in  the  Turridae 
which  partly  through  the  special  method  of  careful  screening 
and  picking  proved  to  be  excessively  abundant  in  both  species 
and  individuals.  This  family  of  difficult  shells  was  worked  up 
by  Mr.  Fargo  and  was  published  as  a  separate  chapter  of  the 
monograph,  the  group  consisting  of  about  87  species,  of  which 
37  forms  were  described  as  new  along  with  4  new  genera.  Cost 
of  publication  and  other  expenses  connected  with  the  Saint 
Petersburg  monograph  were  paid  by  a  grant  from  Mr.  Fargo. 
Since  it  was  realized  that  expanding  real-estate  development 
would  in  the  course  of  a  few  years  cover  the  site  of  the  fossil 
beds,  Mr.  Fargo  and  Mr.  Locklin  promoted  and  finally  succeeded 
in  having  this  interesting  area  set  aside  as  a  park  of  about  26 
acres  so  that  properly  qualified  workers  could  still  be  able  to 
come  here  and  collect. 

Mr.  Fargo  was  a  self-made  man  in  the  best  sense,  who,  having 
achieved  success  in  a  competitive  and  technical  field,  continued 
to  live  simply  and  without  pretension.  He  was  a  modest  and 
highly  sensitive  person,  retiring  and  self  effacing  to  an  unusual 


72  THE   NAUTILUS  [Vol.    71    (2) 

degree,  interested  in  art  and  music,  and  in  all  those  things  which 
contribute  towards  true  progress.  He  never  married.  He  loved 
children  and  they  sought  him  out  and  trusted  him.  At  an  early 
date,  he  began  to  organize  study  groups  for  young  people  which 
he  continued  to  lead  until  well  into  his  eighties.  He  helped  many 
young  men  to  secure  their  higher  education  in  various  branches 
of  science  and  even  in  art.  Fargo  had  a  high  sense  of  civic  re- 
sponsibility and  he  gave  unstintingly  of  his  time  to  the  city  in 
many  hours  of  hard  and  often  thankless  work  to  serve  on  various 
commissions,  all  without  compensation,  until  forced  to  retire  by 
failing  health.  He  served  his  city  for  many  years  as  chairman 
of  a  planning  and  zoning  board  and  in  the  promoting  of  the 
necessary  laws  through  the  state  legislature.  In  the  total,  he 
had  contributed,  over  the  years,  a  large  sum  of  money  to  the  ad- 
vancement of  science,  partly  in  the  financing  of  various  collecting 
expeditions,  donations  and  grants  to  various  museums,  or  for 
publication  needs,  for  the  most  part  given  anonymously.  In 
the  passing  of  Mr.  Fargo,  the  natural  sciences  have  lost  a  true 
friend,  a  man  whose  greatest  joy  was  to  render  service  to  his 
community  and  to  the  advancement  of  his  chosen  fields  of  study.

Mr.  William  H.  Weeks  died  of  heart  trouble.  He  was  87  years 
old.  Mr.  Weeks  had  a  large  hardware  store  in  Brooklyn  until 
illness  compelled  him  to  retire.  He  lived  on  Willoughby  Ave- 
nue. In  his  earlier  days  he  was  a  musician,  and  came  from  a 
musical  family.  He  built  up  a  large  collection  of  shells,  mainly 
from  original  collectors  and  from  missionaries  in  all  parts  of 
the  world,  spending  a  small  fortune  for  shells.  Two  shells  were 
named  in  liis  honor,  ''Helix"  alauda  ivceksiana  Blanes  and 
Fapuina  wceksiana  M.  Smith.  Mr.  Weeks  was  a  kindly  person 
who  radiated  enthusiasm  and  was  always  ready  to  help  be- 
ginners, and  freely  gave  them  of  his  duplicates.     His  collection

GuLELLA  BicoLOR  (Hutton)  IN  FLORIDA. — In  September  1956 
Mr.  Harold  Feinberg  of  the  New  York  Shell  Club  found  a  single 
mature,  live  specimen  of  this  oriental  snail  about  one  block  south 
of  Coconut  Grove  Park,  Coconut  Grove,  South  Miami,  Florida. 
It  is  quite  different  from  any  snails  taken  in  the  east  and  very 
closely  resembles  the  excellent  figure  in  Dr.  Henry  van  der 
Schalie's  The  Land  and  Fresh  Water  Mollus'ks  of  Puerto  Rico 
(Mus.  Zool.,  U.  of  Mich.,  Mis.  Pub.  70,  1948,  pi.  5,  fig.  11a,  lib). 
This  species  has  heretofore  not  been  recorded  from  Florida, 
though  there  is  a  record  from  Charleston,  South  Carolina  (ib., 
p.  69).  It  is  not  mentioned  in  Pilsbry's  Land  Mollusca  of  North 
America,  nor  does  it  appear  in  any  of  the  faunal  lists  from 
Florida.  Unfortunately  no  debris  was  taken  from  the  place 
where  the  snail  was  found  and  hence  no  immature  specimens 
were  collected.  This  species  may  be  presumed  to  be  a  very 
recent  importation,  but,  like  most  molluscan  vagrants,  can  be  ex- 
pected to  make  its  stay  here  permanent.  It  is  widely  but 
sparsely  distributed  in  many  islands  of  the  West  Indies  and 
was  recently  reported  from  Havana.  At  various  times  it  ap- 
peared in  the  genera  Ennea,  Pupa,  Huttonella,  and  Diaphora.

ViviPARus  contectoides  in  Wisconsin. — According  to  Baker's 
monograph  on  the  Gastropoda  of  Wisconsin,  published  in  1928, 
I  find  a  note  that  the  only  record  up  to  that  time  of  Viviparus 
contectoides  in  Wisconsin  was  a  single  shell  found  at  Milwaukee, 
and  of  doubtful  origin.  A  few  days  ago  a  grandson  of  mine 
(Eobert  Chipley),  vacationing  on  the  Chain  o 'Lakes  in  Wanpaca 
county,  brought  me  a  dozen  or  so  living  specimens  collected  on 
the  shore  of  Knight  Lake,  a  small  lake  at  the  upper  end  of  the 
chain.  He  tells  me  that  the  mollusk  was  present  in  large  num- 
bers both  living  and  dead. — Robert  G.  Washburn.

The  Pilsbry  Nautilus 


Vol.  71  JANUARY,  1958  No.  3 

HENRY  AUGUSTUS  PILSBRY 
1862-1957 

Henry  A.  Pilsbry  was  born  December  7/  1862,  on  a  farm  near 
Iowa  City,  in  Johnson  County,  Iowa.  He  was  the  fourth  child  of 
Dexter  R.  and  Elizabeth  (Anderson)  Pilsbry,  both  of  English 
ancestry.  He  was  married  October  20,  1890,  to  Adeline  Bul- 
lock Avery,  whom  he  lost  November  13,  1924.  On  September 
6,  1957,  he  suffered  a  heart  attack  at  the  Philadelphia  Academy 
of  Natural  Sciences,  and  was  taken  to  Jefferson  Hospital,  where 
he  appeared  to  recover.  October  11,  with  his  doctor's  consent, 
he  left  for  his  winter  home  in  Lantana,  Florida,  but  had  another 
seizure  there  on  the  22nd,  and  passed  away  in  his  sleep  October 
26.  He  was  buried  on  the  30th,  beside  his  wife,  in  the  church- 
yard of  St.  Asaph's  which  is  on  Conshohoken  Road,  between 
City  Line  and  St.  Asaph's  Road,  in  Bala  (a  suburb  of  Phila- 
delphia) where  he  resided  during  his  married  life.  The  Pilsbrys 
are  survived  by  two  daughters,  Elizabeth  and  Grace  (Mrs.  Fred- 
erick J.  Barcroft). 

Harry,  which  was  his  Iowa  nickname,  was  educated  in  the 
public  schools  of  Iowa  City  and  at  the  nearby  University  of 
Iowa,  from  which  he  graduated  in  1882  (B.Sc).  He  was  inter- 
ested in  animals  from  an  early  age,  and  soon  was  making  col- 
lections of  them.  At  college,  this  interest  developed  into  a 
desire  for  knowledge  in  paleontology  and  zoology,  especially 
in  class  work  with  Professors  Samuel  Calvin  and  Thomas  H. 
Macbride,  and  on  field  trips,  which  he  felt  privileged  to  share. 
He  first  collected  land  and  fresh  water  shells  at  this  time,  along 
with  his  friend,  Bohumil  Shimek   (1861-1937;  N.50 -.140)2  ^^^ 

1  He  gave  Dee.  8  to  ^' Who's  who  in  America ''  but  changed  it  to  Dec.  7 
(Amer.  men  of  sci.)  because,  as  he  told  us:  *'My  sister  heard  the  clock 
strike  midnight  just  after  I  was  born.  *'

became  a  leading  authority  on  loess  and  its  fossils.  At  first, 
neither  had  any  idea  that  books  had  been  written  about  their 
insignificant  snails  and  mussels,  although  they  had  used  texts 
on  geology  and  paleontology.  But,  through  Prof.  Calvin,  De- 
Kay's  ** Natural  History  of  New  York"  and  Binney  and  Bland's 
''Land  and  fresh- water  shells  of  North  America"  were  obtained, 
and  a  new  world  of  knowledge  was  disclosed. 

After  Harry's  family  left  for  Florida,  several  years  were  spent 
in  various  capacities,  including  that  of  reporter,  with  newspaper 
and  publishing  firms  at  Iowa  City  and  Davenport,  Iowa,  but 
all  his  spare  time  and  evenings  were  devoted  to  the  collection 
and  study  of  mollusks.  During  this  period,  he  met  Dr.  R. 
Ellsworth  Call  (1856-1917)  at  the  Davenport  Academy  of  Sci- 
ences, and  first  published  (1886,  2)^  his  remarkable  skill  at 
drawing. 

He  went  to  New  York  City  as  a  proof  reader  (at  which  he 
had  great  skill)  in  the  summer  of  1887.  But  soon  he  received 
an  invitation  from  George  W.  Tryon,  Jr.  (1838-1888;  P.1888: 
399,  with  portrait)  and  visited  Philadelphia  on  Thanksgiving 
Day.  On  December  1st,  6  days  before  his  25th  birthday,  Harry 
was  installed  as  Tryon 's  assistant  at  the  Academy  of  Natural 
Sciences,  probably  on  the  Jessup  Fund.*  Apparently  he  might 
have  received  up  to  twenty  dollars  a  month  until  he  became  a 
member  (P.1892:505)  about  12  weeks  later  (P.1888  :83).  Tryon 
had  died  quite  suddenly  on  February  5th,  1888,  but  bequeathed 
enough  to  continue  his  work. 

Henry  A.  Pilsbry  succeeded  Tryon  as  Conservator  of  the 
Conchological  Section  (P.1888  :447)  and  as  Editor  of  the  ''Man- 
ual of  Conchology"  (P:405-406).  For  some  years  afterwards, 
the  expenses  of  the  Manual  and  most  of  young  Pilsbry 's  liveli- 
hood came  from  the  sale  of  this  and  other  publications.  Neces- 
sity partially  explained  his  production  of  8  parts  (2  full  vol- 
umes) in  1889,  1890  and  1892,  and  6  in  1891  (the  year  after 
his  marriage),  1893  and  1895.  He  wrote  out  the  text  longhand, 
made  many  of  the  plates  on  lithographic  stone,  which  meant 
that  he  drew  them  as  mirror  images,  and  showed  the  tints  for 
the  colored  and  fine  editions,  which  were  hand  painted  (as  piece

work)  by  Philadelphia  ladies  ^  in  their  homes.  He  also  began 
the  Nautilus  in  1889  (see  ''The  Pilsbry  Nautilus"). 

Frank  C.  Baker  (1867-1942;  N.56 :33,  97-99  &  98-pl.)  as- 
sisted him  in  curatorial  work  during  1889  (P:434)  and  1890 
(P:483),  and  Mrs.  Pilsbry  in  1891  (P:499).  The  American 
Association  of  Conchologists  was  organized  to  assist  the  Section 
in  1890  (P:482;  N.3:140-143)  but  this  promising  society  ap- 
parently broke  down  during  the  "hard  times"  around  1893 
(N.7:83;  10:94).  Charles  W.  Johnson  (1863-1932;  N.46:37, 
73-pl.  &  129),  who  became  Pilsbry 's  partner  in  the  Nautilus 
in  1890,  John  H.  Campbell  (1847-1897 ;  N.10:116),  its  president, 
and  John  Ford  (1827-1910;  N.23  :121-pl.  &  126)  also  were  mem- 
bers. Sherwood  E.  Roberts  (1845-1928 ;  N.42 :37-pl.  &  60),  who 
was  one  of  the  founders  (1866)  of  the  Section,  continued  as 
Treasurer  of  it  and  the  Manual  until  his  death.  Henry  was  to 
outlive  all  these  friends  and  colleagues  of  his  youth,  and  sadly 
to  write  or  edit  their  obituaries. 

Even  with  this  curatorial  help,  young  Pilsbry  undoubtedly 
worked  long  days  and  into  the  night  in  order  to  accomplish  so 
much,  and  one  wonders  that  he  did  not  exhaust  all  his  energies 
in  the  details  of  compilation  and  administrative  work.  Never- 
theless, he  must  have  been  thinking  inductively  all  the  while, 
because  he  finished,  at  the  age  of  32  (1895,  3),  his  "Guide  to  the 
study  of  helices,"  the  most  brilliantly  original,  iconoclastic  book 
that  ever  has  been  written  about  land  snails.  Of  course,  their 
nomenclature  (this  was  8  years  before  the  type  species  "rule") 
and  their  systematics  (with  additions  of  new  data)  have  changed 
much  since  then,  but  this  volume  pointed  the  way  to  all  good, 
subsequent  studies.  And  in  the  same  year,  he  completed  his 
new  classification  of  the  chitons  (1895,  2)  and  published  his 
treatise  on  Japanese  marines  (1895,  18)  collected  by  Frederick 
Stearns  (1832-1907;  N.21:83),  in  addition  to  24  shorter  con- 
tributions. 

Promptly  afterward,  April  2,  1895  (P:211),  he  was  elected 
a  Curator^  of  the  Academy  (one  of  four)  and  made  Professor

replaced  Dr.  W.  S.  W.  Euschenberger  (1807-1895;  N.9:31)  who,  as  Director 
of  the  Conchological  Section  during  the  interim,  had  headed  the  list   of 


76  NAUTILUS  [Vol.  71    (3) 

of  Malacology  (P:563  &  586),  which  meant  he  gave  evening 
lectures;  and  was  given  Edward  G.  Vanatta  (1876-1939;  N. 
52:139)^  for  ''student"  on  the  Jessup  Fund  (P:577).  The 
Academy  building  (1876)  was  completed  in  1894  (P:467)  and 
opened  to  the  public  in  1896  (P:577;  P.1901 :711-pL  A).  Dr. 
Pilsbry  became  Curator  of  Mollusca  in  1901  (P:771).  The  De- 
partment of  IMollusks  was  established  in  1903,  with  him,  at  40, 
as  its  Special  Curator  (N.17,  no.  1,  front  cover;  P.1904:847), 
and  with  Miss  Winchester  as  the  artist  of  the  Manual  (vol. 
16:311).  It  became  the  ''Department  of  Invertebrate  Zoology 
(exclusive  of  Insects)"  in  1919  (P:316). 

In  his  room  (Plate  6)  at  the  top  floor  of  the  Academy,  he 
was  untiring  in  his  mental  exertion.  Impatient  for  results,  he 
seldomed  bothered  with  complicated  techniques,  although  he  was 
an  expert  draftsman.  In  1920,  when  Dr.  Pilsbry  was  57,  his  only 
compound  microscope  was  so  ancient  that  Dr.  Cooke,  Vanatta 
and  I  could  see  little  through  its  clouded  lenses.  He  did  not 
use  a  dissecting  binocular  until  considerably  later.  Habitually, 
his  large  desk  (Pl.7)^  was  piled  high  with  opened  reference 
books,  manuscripts,  bottles  of  preserved  animals,  trays  of  shells, 
and  the  stone  ash-receptacle  for  his  warm  pipes.  But  his  mem- 
ory was  so  good  in  his  prime  that  he  could  pull  out  any  one  of 
them  almost  immediately,  although  this  was  one  of  the  few 
abilities  he  lost  as  he  grew  older.  He  never  was  happy  in  his 
work  unless  he  had  everj^thing  within  arm's  reach,  and  nearly 
w^ould  explode  if  anybody  "disordered"  what  looked  like  a 
clutter.  When  busy,  his  powers  of  concentration  were  excep- 
tional ;  one  soon  learned  that  about  10  minutes  was  enough  con- 
versation;  after  that,  between  puffs,  he  might  answer  "Yes" 
or  "No"  but  he  really  was  not  listening. 

its  officers  (with  the  Conservator  last)  until  1891.  Dr.  Benjamin  Sharp 
(1858-1915)  also  was  ''Director,"  at  least  from  1896  (P:582)  through 
1899    (P:543). 

7  Birth  date  May  2,  1876,  from  his  certificate  of  death  (Jan.  19).  His 
birthplace  was  given  as  Pa.  and  his  father's  name  as  George  V.,  by  his 
wife,  Emma  Greenwood  V.  He  was  still  Assistant  Curator  at  the  Academy 
["of  Fine  Arts"  (sic)].  Unfortunately,  he  left  no  descendants,  for  he 
was  a  fine  and  able  man. 

8  He  was  admiring,  at  87,  a  presentation  copy  from  the  Emperor  of 
Japan.  A  story,  perhaps  mythical,  claimed  that  the  first  question  asked 
General  MacArthur  was:  "How  is  Dr.  Pilsbrv."

Primarily  interested  in  research,  his  collecting  instinct  was  so 
highly  developed  that  at  times  he  seemed  almost  a  little  miserly. 
He  was  not  interested  especially  in  the  exchange  of  shells,  but 
was  extremely  successful  when  he  freely  traded  his  brains  and 
prestige  for  additions  to  the  Academy  collections.  Particularly 
noteworthy,  as  regards  inland  mollusks,  were  his  joint  papers 
on  those  from :  Japan  and  adjacent  regions  with  Yoichiro  Hirase 
(1859-1925  ;  N.39  :67).  Central  and  southwestern  United  States 
with  James  H.  Ferriss  (1849-1926;  N.40:l  &  l-pL).  Mexico 
and  middle  America  with  Anson  A.  Hinkley  (1857-1920;  N. 
34:55  &  37-pl.)  and  Herbert  N.  Lowe  (1880-1936;  N.50:28,  64). 
Jamaica  and  other  West  Indies  with  Dr.  Amos  P.  Brown  (1864- 
1917).  Pacific  islands  with  Dr.  Charles  Montague  Cooke,  Jr. 
(1874-1948;  N.63:33).  Africa  with  Dr.  Joseph  C.  Bequaert. 
As  will  be  noted,  he  outlived  most  of  his  best  friends  and 
students. 

Although  modest  in  his  relations  with  others,  he  was  com- 
pletely self-confident  in  his  research ;  he  knew  that  his  inductive 
reasoning  and  his  taxonomic  intuition  were  better  than  most. 
Perhaps  for  this  reason,  his  worst  papers  (and  actions)  were 
those  printed  in  haste  when  he  learned  that  another  was  studying 
the  same  or  similar  material  (e.g.,  1934,  12).  At  least  during 
his  prime,  he  would  not  put  his  name  on  a  scientific  paper  about 
mollusks  unless  he  did  most  of  the  work  and  all  the  editing. 
For  example,  Dr.  Cooke,  whom  Pilsbry  always  considered  the 
finest  gentleman  he  ever  had  known,  used  to  be  fond  of  stating, 
with  high  modesty,  that  he  never  saw  the  manuscripts  of  some 
of  their  joint  papers  on  Pacific  pupilloids,  although  of  course 
''Montague"  contributed,  all  sorted  into  species  and  genera, 
most  of  the  material.  Except  in  his  youth,  about  the  only  paper 
on  snails  of  which  Pilsbry  was  the  junior  author  was  that  (1902, 
24)  with  Bryant  Walker  (1856-1936;  N.50:28,  59  &  37-pl.). 

One  of  the  best  characteristics  of  Dr.  Pilsbry  was  his  ready 
agreement,  and  in  fact  delight  in  alterations  of  his  earlier  classi- 
fications, if  these  were  based  on  discoveries  of  new  data.  He 
was  well  aware  that  the  natural  content  of  taxonomic  groups 
must  change,  or  at  least  develop  when  more  was  learned  about 
them.  In  his  prime,  he  was  conservative  about  the  artificial  sizes 
of  taxons  (species,  genera,  etc.),  but  became  relatively  less  crit- 
ical of  ''splitting"  during  his  last  decade.     On  the  other  hand, 


78  NAUTILUS  [Vol.  71    (3) 

although  he  readily  brought  his  own  names  up  to  date,  he  was 
irked  by  nomenclatural  changes,  usually  due  to  alteration  of  the 
"rules"  during  his  long  lifetime.  Very  rarely,  when  "in  a 
Puckish  mood,"  did  he  wield  his  prestige  to  establish  dubious 
cognomens ;  thus  he  argued  against  the  use  of  Mesomphix  instead 
of  Haplotrema,  but  contrarily  replaced  Planorbina  guadaloupen- 
sis  by  (Biomphalaria)  Australorhis  glabrata  (1934,  7).  And, 
he  positively  was  pained  by  the  exposure  of  occasional  real  errors, 
such  as  those  caused  by  faulty  optics  (inadequate  microscopes 
or,  when  he  grew  oldest,  his  own  tired  eyes).  Because  his  feel- 
ings would  have  been  hurt,  although  he  would  have  published  a 
correction  immediately,  no  one  ever  told  him  that  figures  274G 
(1946,  11)  and  413C  (1948,  0)  were  actually  one  drawing,  which 
only  represented  the  Succinea. 

In  the  field,  on  his  "vacations"  from  mental  strain,  Henry 
became  the  traditional  U.S.  farm  boy,  who  never  disdained,  and 
in  fact  enjoyed  hard  physical  labor.  Chasing  snails  may  seem 
like  a  sedentary  occupation  to  some,  but  not  to  him  who  has 
tramped  for  miles,  forced  his  way  through  jungles  (with  or 
without  malaria),  climbed  arid  mountains  in  the  blazing  sun, 
and  handled  tons  of  talus,  in  order  to  search  out  living  animals  ® 
in  their  hidden  habitats. 

When  23  years  old,  his  first  long  trip  (1937,  13)  was  to  New 
Braunfels,  Texas,  before  September,  1886  (see  Conch.  Ex.  1:3rd 
p.  of  no.  3),  probably  by  the  way  of  New  Orleans  (1886,  3). 
He  especially  liked  to  reminisce  about  the  1899  expedition  to 
the  Great  Smokies  (N.14:49)  with  George  H.  Clapp  (1858-1949; 
N.62:143),  Ferriss,  H.  E.  Sargent  and  Walker.  He  also  col- 
lected with  Ferriss  on  memorable  trips  from  the  Ozarks  to  Texas 
in  1903  (P:813;  N.16:143)  and  in  the  southwestern  mountains 
(Arizona  and/or  New  Mexico  and  Texas)  in  1906  (N.20:84; 
21:134),  in  1910  (N.24:84)  also  with  Lorenzo  E.  Daniels  (1852- 
1918,  N.32:99,  108-pl.)  and  in  1913  (N.29:60).  He  visited  Cuba 
in  1904  (P:845;  N.26:125),  in  1928  with  Dr.  d'Alte  Welch 
(1929,  2),  in  1938  with  the  A.  M.  U.  (N.52:66-72)  and  briefly 
at  other  times.  Good  collecting  with  "Montague"  in  the  Ha- 
waiian Islands  was  enjoyed  in  1913  (P:702;  N.26:108),  in  1923 

9  Always  important,  but  especially  so  in  the  West  Indies,  where  locality 
records  based  on  "crab"  shells  are  almost  worthless.

on  the  trip  to  AustraUa  (N.37:36)  and  in  1933  (N.47:76). 
During  the  excursion  to  Australia,  he  worked  in  Queensland  and 
on  the  Great  Barrier  Reef  (1925,  1). 

He  reached  his  67th  birthday  on  a  cruise  of  the  *'Mary  Pin- 
chot"  with  the  Hon.  Gifford  Pinchot  (1865-1946),  and  visited 
Grand  Cayman,  Swan,  Old  Providence  and  St.  Andrews  Islands 
in  the  Caribbean  (1930,  6),  Panama  (1930,  12)  and  Cocos, 
Galapagos  and  Marquesas  islands  in  the  Pacific,  during  1929- 
1930  (N.42:143;  43:37).  With  Dr.  Francis  W.  Pennell  (1886- 
1952),  he  collected  extensively  through  northwestern  Mexico, 
where  he  was  very  ill  with  malaria  at  70,  in  1934  (N.48  :33)  and 

1935  (N.49:34).  They  worked  especially  from  Nuevo  Leon  and 
San  Luis  Potosi  to  the  Pacific. 

Between  the  ages  of  31  and  almost  95,  he  went  to  Florida  many 
times:  in  1894  (P:473)  with  Charles  W.  Johnson,  in  1899 
(P:543),  in  1904  (P:845),  and  during  almost  every  winter  from 

1936  (N.50 :141)  to  1957.  He  spent  many  happy  months  (PI.  7) 
on  trips  from  his  winter  home  in  Lantana,  where  he  collected 
especially  with  Paul  P.  McGinty  (1877-1956 ;  N.70 :105),  Paul  L. 
and  "Tom,"  except  when  he  was  visiting  the  Barcrofts.  Of 
course,  these  visits  meant  that  he  was  ''chasing"  snails:  in 
Guatemala  during  1945-1946  (N.59:105)  and  1956-1957,  in  the 
Peruvian  mountains  in  1948  (N.61:144)  with  Axel  A.  Olsson, 
and  around  Argentina  in  1949-1950  (N.63:108).  On  shorter 
"vacations,"  he  also  collected,  by  bicycle  and  auto,  in  Pennsyl- 
vania, Maryland  and  New  Jersey,  in  New  York,  especially  on 
Lake  Champlain,  and  briefly  in  many  other  states.  Again,  he 
outlived  so  many  of  his  favored  companions ! 

Throughout  his  life,  Henry  Pilsbry's  most  outstanding  scien- 
tific contributions  were  his  researches  on  land  snails,  and  he  was 
known  internationally  as  the  pre-eminent  authority  on  Pulmo- 
nata.  At  the  age  of  10  or  11  (1937,  13),  his  first  moUusk  was 
naturally  the  geophile  Pupoides,  and  his  first  paper  (1882)  was 
on  lowan  inland  species.  His  companions  in  Philadelphia,  when 
he  was  27,  recognized  that  his  field  was  ' '  Land  and  Fresh  Water 
Shells  generally"  (N.3:142).  In  the  "Manual  of  conchology," 
series  2,  he  revised  most  of  the  shell-bearing  groups,  beginning 
with  July  1,  1888  (2),  when  he  started  on  the  helicoids  (vols.  4, 
p.  120  to  9,  and  parts  of  13  &  14),  which  always  remained  his 


80  NAUTILUS  [Vol.   71    (3) 

favorites.^*'  After  the  Academy  had  absorbed  the  Manual,  it 
ceased  abruptly  with  the  pupilloids  (vols.  21-28)  on  Nov.  7,  1935 
(9),  when  after  all  he  was  only  72.  He  did  omit  the  Enidae 
and  the  Clausiliidae,  because  he  thought  his  European  material 
insufficient,  the  limacoids  and  other  groups  in  Tryon  's  volumes  1 
and  2,  and  the  Heterurethra.  Also,  often  with  the  help  of 
Vanatta,  he  worked  on  many  slugs,  and  always  was  searching 
for  genera  with  reduced  shells  in  every  family  (1900,  12). 
From  the  times  of  his  ''A  descriptive  classified  catalogue  of 
American  land  snails"  (1897,  13),  which  he  began  at  34,  he 
always  was  looking  forward  to,  and  accumulating  data  and  notes 
for  his  culminating  work  on  ''Land  Mollusca  of  North  America 
(North  of  Mexico) "  (1939,  11  &  1946,  11),  which  he  finished  51 
years  later,  at  the  age  of  85. 

However,  he  was  almost  equally  at  home  in  any  group  of 
mollusks ;  but  he  accented  the  living  ones,  and  seldom  went  back 
beyond  the  more  recognizable  fossils  since  the  Cretaceous  (see 
other  appreciations  in  this  number).  In  addition  to  all  this, 
he  became  the  leading  authority,  since  Charles  Darwin,  on  the 
Cirripedia  or  barnacles,  and  between  the  ages  of  28  (1890,  29) 
and  90  (1953,  7)  published  at  least  25  papers  on  this  crustacean 
group.  Also  when  28,  under  the  seniority  of  William  H.  Dall 
(1845-1927,  N.29:l-pl.;  N.41:l),  he  contributed  a  little  about 
brachiopods  (1891,  13  &  16)  ;  and  even  invaded  the  echinoderms 
when  he  was  51  (1914,  2).  Above  all,  he  was  a  zoologist  of  wide 
ranging  knowledge  and  continuous  curiosity. 

He  always  was  interested  in  zoogeography,  remained  for  much 
of  his  life  a  staunch  advocate  of  ''land  bridges"  (1900,  39,  et 
al.),  but  later  did  recognize  also  the  sporadic  effects  of  ad- 
ventitious dispersal.  He  never  did  think  much  of  Wegener's 
revival  of  "continental  float"  nor  of  Simroth's  "wandering  of 
the  poles."  Like  many  taxonomists,  he  was  weak  in  ecology. 
But,  he  was  much  concerned  with  behavior,  especially  locomotion, 
and  this  affected  thoroughly,  but  perhaps  too  enthusiastically, 
his  classifications. 

Edward  G.  Vanatta  worked  with  him  for  over  40  years,  until 
bedridden  by  atrophic  arthritis  in  1937.  Although  often  they 
seemed  almost  antagonistic  in  their  personal  relations,  Vanatta 

10  Perhaps  this  was  partly  why  he  preferred  the  descending  order  of 
taxonomic  groups,  and  always  put  the  helices  at  the  top. 


January,  1958]  nautilus  81 

and  Pilsbry  were  nearly  perfect  complements  of  each  other. 
Vanatta  was  a  veritable  storehouse  of  technical  knowledge,  per- 
haps the  better  dissector,  and  the  more  patient  teacher.  Vanatta 
was  the  one  who  examined  and  took  notes  on  the  weekly  Academy 
displays  of  new  books  and  periodicals,  classified  them  and  tied 
the  pieces  of  paper  in  bits  of  string  and  then  fetched  the  pack- 
ages when  Pilsbry  started  on  a  new  problem,  and  who  also 
sorted  out  and  brought  up  the  recent  publications  of  most  in- 
terest. Somewhat  phlegmatic  in  temperament,  Vanatta  always 
bore,  with  somewhat  exasperating  calm,  the  fiery,  but  brief  out- 
bursts of  Pilsbry 's  tempers.  When  Pilsbry  was  studying  any 
particular  group,  he  knew  more  about  its  species  than  anyone 
ever  had,  but  Vanatta  was  the  man  to  go  to  when  you  wanted  a 
fairly  close,  quick  identification  of  any  shell  whatsoever.  The 
''Professor"  added  to  the  collections,  but  his  ''Student"  kept 
them.  Vanatta  contributed  greatly  to  Pilsbry 's  greatness,  and 
the  master  missed  his  helper  pitifully  all  those  later  years,  and 
often  seemed  lost  (as  were  things)  without  him. 

Helen  Winchester  (Mrs.  John  E.  Gapp)  was  Dr.  Pilsbry 's 
principal  artist  (P.1912:558)  from  1903  to  around  1950,  and 
illustrated  with  superb  skill,  mainly  in  dry-point  "wash,"  many 
volumes  of  the  Manual  and  of  his  other  papers.  She  learned 
with  him  how  to  use  a  color  spray,  and  made  the  exquisite  plates 
for  the  quarto  monograph  on  New  York  inland  mollusks,  which 
was  finished  in  1925  (N.39:30)  after  7  years  of  work,  but  which 
perhaps  was  their  greatest  disappointment,  because  the  State 
Museum  ^^  failed  to  publish  it.  Such  fine  reproductions  of 
iridescent,  unione  nacre  never  have  been  printed.  A  few  of  the 
anatomic  figures  were  included  in  his  "Land  Mollusca  of  North 
America,"  but  those  on  fresh  water  species  anticipated  studies 
which  have  appeared  since  that  time,  by  himself  and  others. 

For  at  least  two  decades  after  1913  (P:703),  Caroline  Ziegler 
assisted  along  with  Vanatta,  who  was  succeeded  by  Richard  A. 
McLean,  Mrs.  Charles  E,.  Locklin  (daughter  of  Mrs.  May  0. 
McGowan,  at  whose  home  in  Morton,  Pennsylvania,  Dr.  Pilsbry 
lived  during  his  last  summers)  and  John  Dyas  Parker.  J.  Eliza- 
beth Letson  (Mrs.  Bryan;  1874-1919;  N.32:142)  apparently 
helped  voluntarily  in  curatorial  work  around  1897   (P:547)   as 

11  On  his  last  visit,  Dr.  John  M.  Clarke  (1857-1925;  N.39:28),  who 
sponsored  it,  remarked:  "You  know,  Dr.  Pilsbry,  this  book  can't  be  pub- 
lished in  Heaven.'' — H.  W,  Gapp,  in  letter.

later  years. 

Degrees  of  doctor  of  science  were  conferred  on  Henry  A. 
Pilsbry  by  the  University  of  Iowa  in  1899  (when  he  was  36), 
by  the  University  of  Pennsylvania  in  1940,  and  by  Temple  Uni- 
versity in  1941.  Dr.  Pilsbry  received  the  Joseph  Leidy  Mem- 
orial Award  (and  Medal)  in  March,  1928  (Science  67:311). 
He  was  Consulting  Malacologist  of  the  Bernice  P.  Bishop  Mu- 
seum in  Honolulu,  and  Lecturer  in  Zoology  at  the  University  of 
Pennsylvania.  After  1906,  he  was  Foreign  Corresponding  ]\Iem- 
ber  of  the  Academia  de  Ciencias  de  Madrid,  from  1918,  Honorary 
Foreign  Correspondent  of  the  Zoological  Survey  of  India  and, 
after  1919,  Corresponding  Member  of  the  Zoological  Society  of 
London.  He  was  an  Honorary  Member  of  the  Conchological 
Society  of  Great  Britain  and  Ireland,  the  Birmingham  Natural 
History  and  Philosophical  Society,  the  Societe  Royale  zoologique 
de  Belgique,  the  Senckenbergische  naturforschende  Gesellschaft, 
the  California  Academy  of  Sciences  (1932),  the  Sociedad  de 
historia  natural  ''Felipe  Poey, "  the  Sociedad  Malacologica 
''Carlos  de  la  Torre"  and  the  Sociedad  Geologica  del  Peru. 
He  also  was  a  Fellow  (1921)  of  the  American  Academy  of  Arts 
and  Sciences  (Boston),  and  a  member  of  the  Malacological 
Society  of  London,  Sigma  Xi  (Univ.  Pa.,  1922),  the  American 
Society  of  Naturalists  and  the  American  Association  for  Ad- 
vancement of  Science. 

Dr.  Henry  A.  Pilsbry  (at  44)  was  the  first  president  of  the 
American  Conchological  Society  (N.21:94)  in  1907,  and  attended 
a  "Washington  meeting"  at  which  another  organization  was 
considered  in  1914  (N.31 :37-pl.,  which  shows  him  at  51).  On 
April  30,  1931,  he  became  first  president  of  the  American  Malaco- 
logical Union  (N.45:l  &  1-pl.,  at  68)  and  attended  most  of  its 
meetings  including  the  23rd  (July,  1957)  as  a  council  member 
and  Honorary  President  (1936,  N.50:36).  September  22,  1955, 
he  was  elected  Honorary  Life  President  at  the  first  meeting  of 
the  Philadelphia  Shell  Club  (Proc.  do.  1:15);  may  it  long 
flourish  under  the  able  leadership  of  Dr.  R.  Tucker  Abbott,  of 
the  Henry  A.  Pilsbry  Chair  of  Malacology  (1955,  N.68:104). 

As  he  grew  older,  and  lonelier.  Dr.  Pilsbry  became  more 
humanly  lovable,  was  willing  to  spend  time  in  chatting,  and 
mellowed  decidedly  in  his  contacts  with  others.  He  very  much 
enjoyed  his  birthday  parties,  given  during  his  fifteen  last  De-

cembers  by  Anne  Harbison  and  Jeanne  S.  Schwengel.  Also,  lie 
spent  relatively  more  time  on  marine  shells,  perhaps  partly  as 
a  relief  from  his  two  volumes  (really  4)  on  ''Land  Mollusca  of 
North  America"  (1939-1948)  but  probably  more  because  he 
always  recognized  the  popular  trend.  He  did  grow  deafer  and 
perhaps  his  memories  of  recent  happenings  did  become  a  little 
weaker,  although  this  last  was  worst  just  after  his  bout  with 
malaria,  twenty-five  years  ago,  and  from  which  he  recovered  with 
remarkable  resilience.  Physically  he  slowed  down  but,  as  late 
as  1949  (at  86),  he  remarked:  ''Burrington,  I  must  be  getting  a 
little  older ;  when  at  high  altitudes  in  the  Andes,  a  climb  of  more 
than  a  thousand  feet  at  a  time  got  me  out  of  breath!"  In  any 
case,  his  enthusiasm  and  research  drive  never  were  impaired; 
he  corrected  proof  (1957,  7)  in  the  hospital  after  his  next-to-last 
blood  clot,  and  critically  discussed  another  manuscript  (see  p. 
116),  on  which  he  was  working. 

Thus,  Dr.  Pilsbry  outlived  all  his  generation  of  conchologists 
and  companions.  For  at  least  half  a  century,  his  was  the  domi- 
nating inspiration  in  the  field  of  malacology,  primarily  in  Pulmo- 
nata,  but  his  effect  was  great  on  most  groups  of  mollusks. 

Compilations  are  out  of  date  before  they  are  published,  but 
the  increments  of  new  data  and  ideas  are  eternal.  And  so, 
Henry  Pilsbry  is  not  dead !  He  still  is  alive  in  the  memories  of 
his  youngest  friends  and  colleagues,  and  will  live  on  forever  in 
his  ramifying  influence  throughout  the  world.  Although  none 
of  us  can  hope  to  equal  his  contributions,  we  all  together  may 
try  to  fill  in  some  of  the  gaps  he  has  left. — H.  B.  B. 


A  COLOMBIAN  SPECIES  OF  THE  GENUS  RHODEA 

By  H.  a.  pilsbry 

Rhodea  H.  &  A.  Adams  is  a  rather  remarkable  genus  of  few 
species,  confined  to  Ecuador  and  Colombia.  The  etymology  of 
the  name  was  not  given  by  its  authors,  and  remains  dubious. 
It  is  probably  a  senseless  made-up  term,  since  the  Greek  words 
suggested  by  the  spelling  do  not  seem  pertinent. 

Rhodea  barcrofti  new  species.     PL  8,  lower  figs. 

The  shell  is  dextral,  cylindric,  the  apical  fourth  tapering  to  a 
rather  obtuse  summit.  The  tapering  whorls  are  moderately 
convex;  the  last  five  whorls  are  flat,  the  last  whorl  with  a  pro-

jecting  peripheral  keel,  concave  above  it  and  deeply  concave  at 
the  base.  Sculpture  of  close,  stron<?ly  oblique,  straight,  fine 
striae,  remaining  distinct  on  the  last  few  whorls  only. 

The  aperture  is  strongly  oblique,  subtriangular,  the  basal 
margin  straight,  outer  margin  curved  slightly  forward,  inner 
margin  formed  of  a  strong  spiral  callous  ridge,  truncate  at  the 
columellar  base  and  spirally  ascending  the  axis  within,  coiling 
around  a  small  but  distinct  central  cavity  which  viewed  from  the 
base  forms  a  sort  of  false  umbilicus. 

Length  25  mm.,  diameter  in  middle  4  mm. ;  lO^/o  whorls.    Type. 
Length  22  mm.,  diameter  in  middle  3.7  mm.

figured  specimen  No.  211335  ANSP. 

By  its  cylindric  shape  and  prominent  keel,  this  snail  appears 

related  to  B.  wallisiana  Dohrn,  described  from  the  ''upper  Mag- 
dalena  region"  without  more  definite  locality;  but  that  species 
differs  by  its  sinistral  coil  and  larger  size  (length  34  to  36  mm., 
diameter  in  middle  5  to  6  mm.). 

The  smaller  specimen  shown  in  the  right  hand  photograph 
differs  by  having  one  whorl  more  than  the  type.  It  came  in  a 
different  lot,  probably  from  a  different  locality. 

It  is  named  for  Mr.  Frederick  J.  Barcroft,  of  the  American 
Embassy,  in  Bogota  at  that  time,  who  obtained  it  from  the 
Colombian  collector  F.  Medem. 


DR.  PILSBRY   AND   FRESH-WATER   MOLLUSCA 

Dr.  H.  A.  Pilsbry  published  continuously  for  75  years.  Al- 
though his  major  comprehensive  works  were  in  the  field  of  land 
snails,  he  had  an  early  interest  in  the  fresh-water  Mollusca  that 
never  was  lost.  He  collected  and  wrote  about  these  animals  from 
the  very  beginning  of  his  career.  His  first  publication  was  a 
privately  printed  leaflet  published  in  Iowa  City  (1882).  In 
the  introduction  to  this,  Pilsbry  expressed  a  desire  to  exchange 
for  moUusks,  and  particularly  for  land  and  fresh-water  shells. 
In  the  ''Conchologist's  Exchange,"  while  in  Davenport,  he 
carried  an  exchange  advertisement  requesting  fresh-water  shells 
specifically. 

A  perceptive  analytical  mind  coupled  with  lucid  expressive- 
ness was  always  characteristic  of  the  immense  volume  of  work 


January,  1958]  nautilus  85 

published  by  Pilsbry.  He  was  a  master  of  incisive  description. 
His  appreciation  of  the  historic  development  of  malacology,  and 
his  interest  in  geography  and  its  influences,  were  always  re- 
flected in  his  studies. 

A  critical  awareness  of  the  dictum  of  constancy  in  specific 
characters,  and  a  keen  appreciation  of  the  variability  found  in 
many  species,  is  readily  apparent  in  Pilsbry 's  publications. 
Perhaps  no  genus  of  fresh-water  snails  contains  species  more 
difficult  of  apprehension  than  does  Physa.  Pilsbry,  of  course, 
realized  this,  and  his  perceptiveness  of  the  fundamental  reasons 
underlying  these  difficulties  was  expressed  more  than  sixty  years 
ago.  In  a  paper  on  Mexican  Mollusca  (1891,  24),  he  discussed 
the  environmental  influence  on  these  plastic  snails.  The  absence 
of  varices  correlated  with  the  slighter  seasonal  changes  and  the 
absence  of  periodicity  in  growth  is  brought  forth  in  this  work. 
Of  particular  interest  is  his  discussion  of  the  dilation  of  the 
body  whorl.  He  said  (p.  324),  *'I  would  suggest  that  the  form 
in  these  cases  is  correlated  with  an  increase  in  the  capacity  of  the 
air  sack  or  lung,  which  occupies  that  part  of  the  shell.  ...  It  is 
not  unlikely  the  result  of  a  more  continuous  or  prolonged  sub- 
aquatic  residence."  This  phenomenon  appears  to  have  been 
''discovered"  about  once  a  decade  since  then. 

The  same  article  contains  an  excellent  example  of  his  ability 
to  review  bluntly  a  piece  of  work  he  considered  inadequate. 
Of  C.  F.  Ancey's  monograph  on  Pyrgulopsis,  Pilsbry  (p.  329) 
said,  ''This  paper  shows  in  a  high  degree  the  futility  of  writing 
about  things  an  author  knows  nothing  about."  However,  Pils- 
bry also  had  a  flair  for  finding  the  facile  expression  that  could 
so  pleasantly  temper  his  criticisms.  This  is  evident,  for  example, 
in  a  later  work  of  his  on  Mexican  mollusks  (1904,  2)  where,  in 
speaking  of  Physa  osculans  patzcuarensis,  he  calls  attention  to 
Strebel's  earlier  description  of  the  form,  and  comments  (p. 778), 
"He  used  a  preoccupied  name  which  laid  in  ambush  in  a  dense 
thicket  of  text." 

The  most  satisfying  works  to  the  taxonomist  are  those  com- 
prehensive works  that  consider  all  the  known  species  of  a  phy- 
logenetic  group  or  of  a  geographic  area.  This  kind  of  study  also 
provides  the  most  useful  tool  for  those  who  are  applying  the  facts 
of  that  science  in  other  fields  of  biology.  Pilsbry  was  especially 
able  at  such  presentations,  and  a  review  of  his  bibliography  re- 


86  NAUTILUS  [Vol.  71    (3) 

veals  how  productive  he  was  of  these  very  useful  treatises  as 
regards  the  fresh-water  mollusks. 

The  largest  treatise  Pilsbry  published  on  fresh-water  mollusks 
was  co-authored  with  Dr.  Joseph  Bequaert.  The  work  was  a 
monograph  on  the  aquatic  mollusks  of  the  Belgian  Congo  (1927, 
15)  and  was  the  companion  volume  to  his  land  moUusk  volume 
of  that  region.  This  is  a  masterful  treatment  that  reflects  the 
thoughtful  research  and  congenial  cooperation  so  characteristic 
of  Pilsbry. 

The  methodology  of  Pilsbry  in  the  study  of  the  Mollusca  has 
been  appreciated  by  every  scientific  worker  in  the  field.  This 
appreciation  is  recognized  by  statements  such  as  that  made  by 
F.  C.  Baker  in  the  preface  to  his  1945  monograph  on  the 
Planorbidae,  "...  the  terrestrial  pulmonates  .  .  .  have  been 
brought  to  a  high  state  of  precise  classification  from  the  anatom- 
ical studies  of  Dr.  Henry  A.  Pilsbry.  ..."  The  fundamental 
value  of  this  anatomical  approach  to  classification  and  its  appli- 
cation by  other  scientists  is  reflected  in  Baker's  further  state- 
ment, "The  study  of  the  internal  organization  of  the  family 
Planorbidae  has  shown  that,  as  in  the  case  of  the  land  snails, 
the  anatomy  gives  the  only  true  key  to  a  natural  classification." 
Surely  Pilsbry  must  be  credited  with  establishing  the  founda- 
tions for  the  modern  classification  of  both  the  land  and  fresh- 
water gastropods.  F.  C.  Baker  recognized  the  value  of  Pilsbry 's 
contribution  nearly  fifty  years  ago  when  he  dedicated  his  1911 
monograph  on  the  Lymnaeidae  to  Pilsbry  in  grateful  recognition 
of  his  "helpful  advice." 

The  pressure  of  constant  researches,  often  conducted  concur- 
rently on  unrelated  materials,  necessarily  resulted  in  occasional 
lapses.  Pilsbry  was  always  the  first  to  correct  his  mistakes  or 
apologize  for  a  hasty  act.  For  example,  S.  N.  Rhoads  published 
on  the  shells  from  the  vicinity  of  Miami  (N.13 :43-48,  1899). 
Pilsbry  made  all  the  identifications  for  this  paper,  including 
(p.48)  an  MS  name,  Physa  heterosfropha  peninsulae.  This,  of 
course,  was  a  nomen  nudum  as  used.  In  a  later  number  (1899, 
31),  Pilsbry  calls  attention  to  this  MS  name,  and  points  out  that 
the  specimens  were  actually  Physa  cuhcnsis  Pfr.  And  again, 
in  a  note  on  Unionidae  and  Mutelidae  (1893,  12),  he  corrects 
an  error  in  a  paper  previously  published  by  Ihering  in  the 
Nautilus.     At  the  same  time,  he  appended  a  footnote  apology: 


January,  1958]  nautilus  87 

"The  Editor  fears  that  these  errors  may  have  been  due  to 
his  own  hasty  proof-reading,  rather  than  to  defects  in  the 
original  MS. ' ' 

Pilsbry  one  time  wrote  (1917,  1),  ''Rafinesque  has  the  reputa- 
tion of  having  been  a  misunderstood  and  neglected  genius.  It 
is  lucky  that  we  had  few  such  geniuses.  One  or  two  others 
would  have  practically  scrapped  the  nomenclature  of  our  fresh- 
water shells."  This  pithy  comment  was  a  prelude  to  a  discus- 
sion of  certain  of  Rafinesque's  genera  of  fresh-water  shells. 

But  Rafinesque  was  the  cause  of  one  of  the  soundest  policies 
for  taxonomists ;  though  it  is  rarely  practised.  This  came  about 
through  the  efforts  of  two  outstanding  workers  in  the  field  of 
fresh-water  mollusks:  Dr.  Arnold  E.  Ortmann  (1863-1927;  N. 
40:109)  and  Bryant  Walker.  These  gentlemen  were  long-time 
correspondents  and  colleagues  of  Pilsbry.  Both  were  deeply 
interested  in  the  Unionidae,  and,  at  one  time,  undertook  to 
stabilize  the  nomenclature  of  this  family  (1922,  5a).  The  most 
controversial  facet  of  their  problem  was  the  many  species  Ra- 
finesque so  inadequately  described.  Their  introduction  in- 
cluded this  statement,  ''At  the  inception  of  the  work  it  was 
agreed  by  the  authors  that  their  conclusions  should  be  submitted 
to  Dr.  H.  A.  Pilsbry  for  his  criticism  and  that  in  all  cases  where 
they  were  unable  to  agree  his  decision  should  be  final  and  ac- 
cepted by  the  authors."  No  statement  can  better  demonstrate 
Pilsbry 's  stature  in  the  field  of  fresh-water  mollusks.  In  effect, 
this  paper  contains  the  unanimous  opinion  of  three  men  who 
sat  as  a  court  to  resolve  objectively  some  troublesome  problems. 
Dr.  W.  J.  Clench  (N.43:69-70,  1929)  discussed  the  value  of  such 
a  policy  and  reflected  the  opinion  of  every  objective  worker  in 
his  commendation  of  it.  With  this  cooperative  example  before 
us  the  time  well  may  come  when  other  problems  of  limited  extent 
will  be  resolved  by  similar  joint  action  of  a  few  competent 
authorities. 

But  now  the  greatest  authority  will  no  longer  participate.

DR.  H.  A.  PILSBRY  IN  MARINE  MALACOLOGY 

Malacology  may  be  divided  into  several  fields,  that  of  the 
marines  being  the  most  colorful,  and  with  the  greatest  diversity 


88  NAUTILUS  [Vol.   71    (3) 

in  size  and  shape.  Dr.  Pilsbry  's  interest  in  shells,  land  and  fresh 
water,  began  early  in  his  youth,  in  Iowa,  wdth  collecting  when- 
ever and  wherever  he  found  the  time,  \yith  his  characteristic 
curiosity  and  thoroughness,  he  became  more  and  more  interested 
as  his  collecting  progressed.  Desiring  to  know  more  about  his 
findings,  he  spent  as  much  time  as  possible  on  his  shells. 

In  1887,  George  W.  Tryon,  Jr.,  Conservator  of  the  Concho- 
logical  Section  at  the  Academy  of  Natural  Sciences  of  Philadel- 
phia, noting  the  interest  of  young  Pilsbry,  invited  him  to  the 
Academy,  and  suggested  that  he  give  up  his  newspaper  work 
and  devote  his  time  to  the  field  in  which  he  showed  such  interest 
and  promise.  A  few  days  before  Pilsbry 's  25th  birthday,  he 
accepted  Tryon 's  offer  and  became  a  member  of  the  Academy 
staff.  When  Tryon  died,  about  two  months  later,  Pilsbry  fell 
heir  to  his  position  as  Conservator. 

Previously  Henry  Pilsbry 's  whole  interest  had  been  in  land 
and  fresh  water  shells,  but  since  his  predecessor  already  had 
completed  nine  volumes  of  the  Manual  of  Conchology,  Marine 
Series,  and  about  160  pages  of  volume  10,  he  felt  that  he  should 
complete  the  work,  and  with  thoroughness  and  extreme  interest 
began  his  first  studies  on  marine  malacology  with  the  "Mono- 
graphs of  the  Turbinidae  and  Trochidae."  His  inscription  on 
volume  10  (1888,  3)  of  my  copy  reads,  without  further  comment: 
''This  volume  contains  my  first  work  in  systematic  malacology. 
H.  A.  Pilsbry."  But,  the  inscription  on  volume  11  (1889,  1) 
reads:  ''This  is  the  first  complete  volume  I  wrote.  I  spent  at 
least  a  year  of  my  lost  youth  over  it,  and  was  very  proud  of  what 
I  had  done.  Alas!  when  I  learned  enough  to  see  its  faults,  my 
pride  evaporated. — H.  A.  Pilsbry." 

Such  modesty  and  humility  in  the  man  were  astonishing. 
With  no  previous  experience,  by  March,  1890,  when  only  27, 
he  had  amassed  a  volume  of  519  pages  and  67  pages  of  illustra- 
tions, which  was  comparable  to  the  best  works  by  scientists  of 
vastly  more  experience  and  knowledge  of  the  subject ;  and,  in 
many  ways,  his  was  much  more  thoroughly  and  competently 
done.  In  the  next  four  years,  he  completed  four  more  volumes 
of  the  Manual,  and  in  four  more  years  finished  the  last  two 
volumes,  which  ended,  on  his  36th  birthday,  the  17  volumes  of 
the  Manual  of  Conchology,  Marine  Series,  the  hihle  of  profes- 
sionals and  amateurs. 


January,  1958]  nautilus  89 

In  1900,  in  recognition  of  his  intense  interest  and  colossal 
accomplishments  in  the  fields  of  malacology,  he  was  given  the 
well-deserved  degree  of  Doctor  of  Science  by  the  State  University 
of  Iowa.  From  then  on,  his  work  was  constant ;  and  his  publi- 
cations of  untold  value  to  the  collector  and  student,  both  in  the 
field  of  marine  mollusks  and  other  subjects  malacological.  For 
those  who  knew  him,  his  going  is  a  great  loss,  though  future 
years  will  be  filled  with  pleasant  and  enjoyable  memories.  Those 
who  never  knew  him  personally  have  our  deepest  sympathy.

PILSBRY  ON  FOSSIL  AND  MARINE  MOLLUSCA 

Dr.  Pilsbry's  broad  interest  in  mollusks,  like  that  of  Dall,  led 
him  naturally  to  the  study  of  Tertiary  forms,  generally  in  col- 
laboration with  other  authors;  thus  he  carried  on  the  tradition 
set  by  other  members  of  the  Academy,  such  as  Say,  Conrad 
and  Gabb. 

For  many  years,  the  occurrence  of  beautifully  preserved, 
Tertiary  fossils  in  the  Caribbean  region  had  become  known 
through  the  work  of  European  authors,  who  regarded  the  age  of 
these  fossiliferous  formations  as  Miocene,  correlated  them  di- 
rectly with  the  European  section.  The  age  assignment  of  these 
Caribbean  horizons  had  been  changed  to  Oligocene  by  Dall,  the 
principal  Tertiary  authority  in  America  at  that  time.  Pilsbry 
followed  Dall  in  this  assignment  although  later  studies  have 
reaffirmed  their  true  Miocene  age. 

Pilsbry's  first  papers  on  Caribbean  paleontology  began  with 
two  articles  on  the  Panama  Canal  Zone  with  Amos  P.  Brown 
(1911,  8  &  1913,  1).  These  fossils  had  been  collected  by  Brown 
from  dumps  and  fills  resulting  from  the  excavations  for  the 
Gatun  locks.  They  listed  about  136  species  of  which  nearly 
half  were  described  as  new,  the  entire  fauna  being  well  illus- 
trated. The  close  relationship  and  age  of  the  Isthmian  fauna 
with  that  of  Bowden,  Jamaica  and  Santo  Domingo  were  noted. 
They  also  called  attention  to  the  frequency  of  many  character- 
istically Panamic  (Pacific)  genera  (Cymia,  Malea,  Tesseracme, 
etc.)  in  the  Antillean-Isthmian  Miocene,  now  all  absent  or  very 
rare  in  the  curiously  impoverished,  littoral  Antillean  fauna  of  the 


90  NAUTILUS  [Vol.   71    (3) 

present  time.  These  two  papers  have  remained  the  principal 
contributions  to  the  paleontology  of  the  Gatun  I\Iiocene,  although 
some  additions  have  been  made  to  its  fauna  since. 

Along  with  these  studies  on  the  Canal  Zone,  Pilsbry,  together 
with  C.  W.  Johnson,  had  for  some  time  been  engaged  in  a  re- 
vision of  the  collection  of  ]\liocene  mollusks  from  Santo  Domingo, 
which  had  been  obtained  by  William  M.  Gabb  during  geological 
investigations  in  the  years  1869-71.  Gabb,  following  the  earlier 
paleontologists,  assigned  these  deposits  to  the  Miocene.  Whether 
through  the  loss  or  the  lack  of  field  labels,  no  locality  records 
existed  for  any  part  of  this  great  collection,  although  practically 
all  now  is  known  to  have  come  from  the  north  side  of  the  island, 
or  from  beds  exposed  in  the  gorges  of  the  upper  Rio  Yaque  del 
Norte,  or  from  its  tributary  streams,  such  as  the  Mao,  Gurabo 
and  Cana  to  the  west.  Gabb  had  done  some  preliminary  work 
on  the  material,  and  described  many  new  species,  none  of  which 
had  been  figured,  but  his  publications  showed  much  evidence  of 
haste.  In  revisional  studies,  Pilsbry  and  Johnson  differentiated 
many  additional  new  species,  and  described  these  in  a  prelimi- 
nary paper  (1917,  10).  After  Johnson's  transfer  to  Boston, 
the  final  studies  devolved  upon  Pilsbry  alone.  In  his  final  paper 
(1922,  1),  much  more  detailed  and  fully  illustrated,  Gabb's  types 
were  figured  and  their  dimensions  accurately  stated  for  the  first 
time,  besides  the  new  species  described  in  1917.  Pilsbry 's  work 
on  these  Santo  Domingan  fossils  is  a  major  contribution  to 
Antillean  geology,  and  because  of  its  and  the  stratigraphic  re- 
sults of  the  Maury  expedition  in  1917,  the  Miocene  of  northern 
Santo  Domingo  may  be  selected  as  the  type  for  the  w^hole  of  the 
Antillean  region.  Two  smaller  papers  on  this  region  were  that 
in  collaboration  with  B.  Sharp  on  the  Scaphopoda  from  Jamaica 
and  Costa  Rica  (1911,  4)  and  another  with  Brown  on  Miocene 
fossils  from  Colombia  and  Haiti  (1917,  4). 

Two  important  papers  formed  Pilsbry 's  main  contribution  to 
fossil  fresh-water  mollusks.  The  first  dealt  with  material  from 
the  Pliocene  beds  of  the  Kettleman  Hills  and  neighboring  oil 
fields  in  California  (1935,  2).  Pilsbry 's  chief  incentive  in  his 
studies  was  its  intrinsic  interest  as  representing  the  largest 
Pliocene  fresh-water  molluscan  fauna  yet  found  on  the  Pacific 
slope.  Largely  made  up  of  Amnicolidae,  it  consisted  of  about 
23  species  or  subspecies  belonging  to  7  genera,  of  which  2  are 


January,  1958]  nautilus  91 

extinct.  This  fossil  assemblage  differed  conspicuously  from  the 
living  fauna  of  middle  California  by  the  lack  of  Lymnaeidae, 
Ancylidae  and  the  larger  Planorbidae,  old  but  living  groups 
which  are  widespread  in  America  today.  He  concluded  that 
these  Pliocene  beds  had  been  laid  down  in  a  lake  of  considerable 
size  because  the  development  of  so  rich  a  molluscan  population 
would  be  unlikely  in  a  small  one. 

Oil  geologists,  exploring  along  the  valley  of  the  Rio  Magdalena 
in  Colombia,  had  come  across  fresh-water  fossils  at  several  places, 
but  paid  comparatively  little  attention  to  them  at  first.  Even- 
tually these  fossils  were  recognized  as  occurring  only  at  certain, 
fixed  stratigraphic  horizons,  which  could  be  used  as  key  beds  to 
map  and  unravel  complex  geologic  structure  and  as  marker 
horizons  in  drilling  operations.  Attention  to  the  collecting  of 
these  fossils  increased,  and  an  assemblage  of  the  more  important 
species  made  by  A.  A.  Olsson  became  the  subject  of  a  special 
paper  by  Pilsbry  and  him  (1935,  4),  which  also  contained  an 
account  of  the  stratigraphy  by  0.  C.  Wheeler.  The  fresh-water 
fossils  came  from  three  horizons.  The  oldest,  named  the  Los 
Corros  zone,  was  characterized  by  several  large  Potamides  and 
a  new  genus  (Diplocyma)  which  is  nearest  to  forms  from  the 
Upper  Eocene  of  Peru.  These  potamidids  were  associated  with 
corbiculids  (Sogamosa),  suggestive  of  an  estuarine  or  brackish 
environment,  probably  of  Upper  Eocene  age.  The  two  overlying 
horizons,  named  the  Mugrosa  and  La  Cira  zones  and  considered 
Oligocene,  contain  a  very  different  fauna,  characterized  by  river 
melanids  (such  as  Hemisinus  of  very  modern  aspect),  Potamo- 
pyrgiis,  small  naiades  (Triplodon  and  Diplodon),  Mytilopsis, 
Ostomya  and  small  corbulids.  The  La  Cira  zone  is  the  most 
extensively  distributed  elsewhere.  Because  of  its  importance, 
this  paper  and  Wheeler's  were  translated  into  Spanish  and  re- 
published (1941,  3a). 

In  1944  (7)  Pilsbry  wrote  a  short  paper  on  molluscan  fossils 
from  the  Rio  Pachitea  in  eastern  Peru,  which  contained  two  lots : 
one  (marine)  from  the  Cretaceous  and  the  other  (non-marine) 
from  the  Tertiary.  The  Tertiary  ones  include  some  of  the 
genera  (but  different  species)  of  the  La  Cira  zone,  and  the  strik- 
ing resemblance  of  the  two  faunas  undoubtedly  indicates  that 
they  are  about  equivalent  in  age.  This  contribution  also  was 
translated  (1947,  3a). 


92  NAUTILUS  [Vol.   71    (3) 

In  his  later  years,  Pilsbry  wrote  several  important  papers  on 
marine  fossils,  of  both  mollusks  and  barnacles.  One  (1941,  2), 
prepared  in  collaboration  with  Olsson,  described  a  Pliocene  mol- 
lusk  fauna  from  Ecuador ;  it  consisted  of  237  species,  of  which 
54%  belong  to  forms  still  living.  An  unexpected  member  was 
a  large  Cypraea,  of  the  C.  henekeni  group,  characteristic  of  the 
Antillean  Miocene  and  its  first  record  from  the  Pacific  slope  and 
at  such  a  high  horizon. 

Pilsbry 's  final  work  in  paleontology  was  his  report  on  the 
vitrinellids  and  fresh-water  mollusks  contained  in  the  Fargo- 
Locklin  collection  from  the  Pliocene  of  St.  Petersburg,  Florida. 
His  account  of  these  fossils  constituted  the  two  final  chapters 
(1953,  8)  in  the  memoir  on  the  Pliocene  of  southern  Florida  pub- 
lished in  the  monograph  series  of  the  Academy. 

In  addition  to  the  fossil  mollusks,  Pilsbry  contributed  many 
papers  on  the  fossil  Cirripedia,  his  largest  work  (1953,  11)  dealt 
with  some  Cretaceous  and  Tertiary  forms  from  Peru  and  Ecua- 
dor and  was  prepared  in  collaboration  with  Olsson.  The  Creta- 
ceous forms  were  scalpellids  and  represent  7  species  distributed 
amongst  2  genera.  The  Tertiary  ones  were  balanids  from  the 
Oligocene  and  Miocene.  The  balanid  barnacles  are  often  com- 
mon in  our  later  Tertiary  rocks,  but  usually  indeterminable 
unless  the  opercular  valves  are  found  attached  to  the  cup  or  in 
close  association  with  the  separated  valves. 

Among  living  mollusks,  outside  the  Pulmonata,  Pilsbry  worked 
most  extensively  on  marine  gastropods  and  chitons,  and  miich 
less  on  bivalves.  When  he  took  over  the  ''Manual,"  his  prede- 
cessor Tryon  had  completed  9V2  volumes  of  the  marine  series, 
which  included  the  cephalopods.  Tryon 's  extremely  conserva- 
tive views  on  their  systematics  aimed  toward  a  reduction  of  the 
described  species,  which  he  deemed  excessive,  and  so  his  volumes 
bear  the  impress  of  ''lumping"  and  are  useful  mainly  for  their 
wealth  of  illustrations  copied  from  the  older  iconographs.  Pils- 
bry, in  contrast,  worked  directly  with  the  shells,  studied  the 
anatomy  and  radula  when  necessary,  and  hence  was  able  to 
judge  relationships  more  clearly.  Although  Pilsbry  knew  the 
literature  intimately,  he  never  was  a  name  changer,  for  this  end 
alone,  but  a  research  scientist,  primarily  interested  in  the  ani- 
mals themselves ;  and  his  work  derived  its  lasting  qualities  largely 
from  this  distinction.     Systems  of  classification  and  ideas  of 


January,  1958]  nautilus  93 

nomenclature  may  change,  but  the  fundamental  basic  data 
worked  out  by  Pilsbry  remain. 

In  1891  (19)  began  the  important  volume  devoted  to  the 
limpets  or  Docoglossa  and,  as  noted  in  its  introduction,  the  mate- 
rial studied  included  the  collection  of  the  U.  S.  National  Museum 
as  well  as  that  of  the  Academy.  From  1892  to  1895  (2),  volumes 
14  (1893,  11)  and  15,  on  the  Amphineura  or  chitons,  appeared. 
Pilsbry  raised  the  Amphineura  to  class  rank  in  the  mollusk 
phylum.  He  divided  them  into  Polyplacophora,  or  chitons,  and 
Aplacophora  (solenogasters),  which  may  not  be  mollusks.  He 
subdivided  the  chitons  proper  into  superf  amilies,  which  he  named 
Eoplacophora,  Mesoplacophora,  and  Teleoplacophora.  In  the 
Eoplacophora,  the  rare  Paleozoic  forms  belong  to  one  family, 
Gryptochitonidae  Pilsbry  (1900,  18).  Numerous  Lepidopleuri- 
dae  occurred  in  the  Tertiary,  and  a  form  close  to  Lepidopleurus 
has  been  found  in  the  Triassic  of  Germany  (1901,  16).  The 
Mesoplacophora  are  recent.  The  Teleoplacophora  are  the  most 
advanced  chitons.  Pilsbry 's  work  on  the  Amphineura  will  re- 
main a  classic  and,  although  his  classification  has  been  modified 
somewhat  by  a  few  later  students,  its  essentials  remain  largely 
unchanged. 

The  Scaphopoda  and  Aplacophora  brought  to  completion  the 
first  series  of  the  "Manual"  about  20  years  after  its  commence- 
ment. As  in  the  chitons,  Pilsbry 's  ideas  on  classification  evolved 
during  the  course  of  study  and  were  not  presented  fully  until 
the  end  (1898,  28).  A  thorough  review  and  illustration  of  all 
the  living  species  of  scaphopods  then  known  were  given,  and  a 
catalogue  of  fossil  species  was  prepared  with  B.  Sharp. 

Outside  of  the  ''Manual,"  Pilsbry  contributed  numerous 
papers  on  marine  mollusks  from  many  parts  of  the  world.  Sev- 
eral on  marine  Japanese  shells  were  written  with  Y.  Hirase,  for 
whom  he  named  a  lovely  Fleiirotomaria.  In  1932  (12),  Pilsbry 
and  Lowe  published  their  paper  on  west  Mexican  and  Panamic 
shells,  one  of  the  most  important  contributions  to  this  fauna  ever 
produced,  with  its  fine  illustrations  and  detailed  descriptions  of 
many  species,  of  which  121  were  described  as  new. 

In  his  later  years,  Pilsbry  became  interested  in  the  vitrinellids 
and  other  small  shells  often  placed  with  them.  The  true  vitrinel- 
lids appear  to  be  taenioglossate  and  allied  to  the  rissoids,  but 
other  similar  forms  are  rhipidiglossate,  and  several  families  of 


94  NAUTILUS  [Vol.   71    (3) 

distinct  origin  and  lineage  may  be  involved.  Since  Vitrinella 
C.  B.  Adams  (1850)  became  the  basis  for  Katherine  Bush's 
(1897)  Vitrinellidae,  Pilsbry's  first  step  was  to  obtain  a  loan  of 
the  Adams  collection.  Excellent  drawings  of  Jamaican  (1946, 
1)  and  Panamic  species  were  made  by  Helen  Winchester,  and 
eventually  published.  In  close  collaboration  with  Thomas  P. 
McGinty,  the  Florida  forms  received  attention  first  (1945,  7  to 
1950,  2).  The  Pacific  species  also  were  studied  and,  in  collabora- 
tion with  Olsson,  two  fairly  large  papers  on  Panamic-Pacific 
species  were  published  (1945,  12  &  1952,  5).  This  last  fauna 
appeared  much  richer  than  the  Caribbean,  and  comprised  137 
known  species. 

The  preceding  review  gives  but  a  very  incomplete  picture  of 
the  vast  amount  of  work  accomplished  by  Pilsbry  on  marine 
mollusks,  the  hours  of  unremitting  toil,  careful  identifications, 
searches  of  literature,  etc.  Few  malacologists  have  done  so 
much ;  none  have  done  better. — Axel  A.  Olsson. 


HENRY  PILSBRY,  ZOOLOGIST  AND  MAN 

In  Pilsbry,  the  man  and  the  zoologist  became  so  completely 
enmeshed  and  consolidated  through  the  years  that  any  attempted 
separation  would  do  both  violence.  The  same  attributes  that 
made  him  a  great  zoologist  made  him  an  excellent  man.  Among 
them  were:  1)  a  mind  both  plastic  and  retentive  (''wax  to  re- 
ceive and  marble  to  retain")  ;  2)  great  capacity  for  industry 
and  concentration;  3)  skilled  hands  and  clear  eyes,  as  shown  by 
his  delicate  dissections  and  finished,  accurate  drawings;  and  4) 
complete  honesty  in  thought  and  speech.  Other  qualities,  be- 
longing more  to  the  man  but  not  denied  the  zoologist,  were : 
good  fellowship  and  cooperativeness,  a  soft  and  even  voice,  a 
good  sense  of  humor  and  a  love  of  adventure. 

He  was  born  potentially  a  zoologist,  but  this  remained  nascent 
while  the  child  on  the  Iowa  farm  absorbed  the  ways  of  Nature 
among  the  birds,  bees  and  butterflies.  He  might  have  become 
an  ornithologist  or  entomologist,  but  there  were  molluscan  shells 
weathered  or  chipped  from  the  Devonian  rocks,  and  snails  and 
mussels  in  the  Iowa  River  to  be  gathered  and  treasured.  He 
himself  tells  how  at  the  age  of  11,  he  first  saw  the  little  snail 


I 


January,  1958]  nautilus  95 

Pupoides  on  an  apple  tree  and  wondered  how  it  got  there.  This 
was  the  real  beginning  of  his  interest ;  the  zoologist  in  him  fully- 
awakened,  and  he  wondered  about  snails  and  their  distribution 
throughout  his  long  and  busy  life. 

When  he  came  to  the  Academy  in  1887,  it  was  still  in  what 
H.  F.  Osborn  called  its  Golden  Age,  with  Leidy,  Cope,  Ryder, 
Heilprin  and  others  still  active,  and  for  its  sole  purpose  the 
encouragement  and  advancement  of  the  natural  sciences  wher- 
ever they  occurred.  The  Academy  was  poor  but  highly  re- 
spected and  productive. 

In  this  favorable  environment  and  with  practically  full  con- 
trol of  his  time,  Pilsbry  soon  sprang  into  extraordinary  produc- 
tivity, and  so  continued  till  his  death.  The  bulk  of  his  pro- 
digious output  was  original  matter,  based  on  exacting  laboratory 
and  field  work. 

Pilsbry 's  work  was  largely  systematic,  but  it  was  far  more  than 
the  simple  descriptions  of  new  species  and  genera.  His  early 
acceptance  of  evolution  and  his  knowledge  of  paleontologic  suc- 
cession led  to  the  construction  of  phylogenies  that  also  fitted  the 
facts  of  comparative  anatomy.  Knowing  that  the  ecologic  con- 
ditions, under  which  certain  kinds  of  mollusks  live,  were  similar 
to  those  that  furnished  the  raw  materials  for  the  production  of 
fossil  oils,  enabled  him,  by  identifying  the  fossil  shells  in  their 
rock  cores,  to  guide  the  exploratory  drilling  of  oil  geologists. 
On  the  other  hand,  he  helped  health  officers  to  solve  their  prob- 
lems, because  living  fresh-water  snails  are  the  hosts  of  inter- 
mediate stages  of  parasites  of  man  (especially  trematodes)  and 
domestic  animals. 

In  the  mechanics  of  systematics,  his  descriptions  were  well 
founded  on  external  and  internal,  anatomical  characters,  and  his 
nomenclature  on  exhaustive  study  of  the  literature  and  a  reason- 
able set  of  rules.  He  disliked  both  the  extreme  ''splitting"  of 
genera  and  the  pleas  of  nomenclatural  lawyers  who  seek  stability 
in  new  laws. 

In  the  laboratory,  Pilsbry 's  industry  and  powers  of  concentra- 
tion were  best  displayed.  He  worked  late,  often  on  Sundays 
and  holidays,  and  at  night  took  his  work  home.  His  clean  dis- 
sections were  made  with  scalpel  and  needle  under  a  lens ;  never 
with  a  mechanical  micro-dissector.  He  was  a  constant  smoker 
in  the  face  of  a  ''No  Smoking"  sign  in  his  own  office.     When 


96  NAUTILUS  [Vol.  71    (3) 

another  was  present,  he  could  dissect,  smoke  and  converse  at  the 
same  time,  but  if  a  visitor  stayed  too  long,  the  conversation 
slowed  and  became  monosyllabic,  and  there  was  one  shell  collector 
(J.)  in  particular  who  made  long  and  frequent  visits.  One  day 
when  I  entered  his  room,  he  seemed  very  glum.  To  my  ' '  What 's 
the  matter,  Pilsbry ?' '  he  replied :  ' ' Oh,  this  Academy  never  has 
any  luck.  J.  was  just  in  here  telling  me  how  he  was  in  Florida 
and  in  stepping  over  a  log  almost  trod  on  a  big  water  moccasin. 
And  the  thing  never  bit  him ! ' ' 

He  was  even  happier  in  the  field  and,  besides  short  walks  for 
recreation,  took  ''vacations"  whenever  possible  to  more  distant 
countries,  usually  with  other  shell  collectors.  One  of  these  was 
with  Gifford  and  Mrs.  Pinchot  in  their  yacht.  About  this  one, 
Pinchot  telegraphed,  on  the  occasion  of  Pilsbry 's  85th  birthday 
celebration:  "He  was  one  of  the  best  outdoor  men  and  best 
companions  anyone  ever  traveled  with." 

He  was  thorough  and  resourceful  in  finding  his  desiderata, 
whether  they  were  under  logs,  buried  in  the  humus  of  the  forest 
floor,  up  a  tree,  or  in  clefts  of  the  rock  of  a  cliff.  During  World 
War  II,  when  parts  of  our  Atlantic  coast  were  under  military 
occupation  as  a  precaution  against  submarine  landings,  Pilsbry 
was  wintering  with  his  daughter  in  Lantana,  Florida.  He 
wished  to  collect  along  the  shore  but  was  forbidden.  So  he 
induced  his  son-in-law,  who  was  the  Mayor,  to  appoint  him  a 
policeman  and,  with  badge  and  commission,  he  was  free  to  arrest 
the  shells  that  illegally  had  rolled  up  the  beach  on  the  incoming 
tides. 

He  was  fond  of  camping  and  one  of  his  innovations,  designed 
to  keep  his  boots  pliable  and  waterproof,  was  to  pour  hot  bacon 
fat  inside  instead  of  outside.  This  surely  was  an  effective  lubri- 
cant to  prevent  foot  blisters. 

His  intimate  knowledge  of  the  distribution  of  living  snails 
and  their  fossil  forebears  enabled  him  to  postulate  past  migra- 
tions between  North  and  South  America  via  West  Indian  land 
connections.  Also  he  showed  that  the  snails  of  our  Pacific  states 
came  from  Asia  by  the  same  Bering  Isthmus  route  as  did  our 
aboriginal  men  and  large  mammals. 

On  matters  of  Academy  policy  and  administration,  Pilsbry 
always  stood  quietly  but  firmly  for  the  interests  of  scientific 


January,  1958]  nautilus  97 

research  and  advancement.  As  an  example,  when  the  proposal 
first  was  made  to  establish  a  central  office  to  handle  all  clerical, 
accounting  and  similar  functions,  which  previously  had  been 
done  by  each  individual  or  department,  he  strongly  opposed  it. 
But  after  the  Council  had  adopted  and  put  it  into  action,  he 
saw  that  it  saved  the  curators  and  other  researchers  much  time. 
He  then  wrote  me  a  letter,  explained  that  he  had  thought  that 
it  was  a  plan  to  put  the  scientific  departments  under  office  con- 
trol, but  now  saw  otherwise.  Scanning  the  increasing  centrali- 
zation during  the  passing  years,  one  questions  whether  Pilsbry's 
first  position  may  not  have  been  the  better — whether  freedom 
was  not  being  sacrificed  to  efficiency. 

Pilsbry's  home  life  was  simple  and  happy.  So  far  as  I  know, 
he  had  no  hobbies,  except  his  garden.  He  was  not  interested 
in  athletics,  politics  or  art.  Occasionally,  he  enjoyed  the  theater 
and  was  fond  of  reading  the  biographies  of  great  men. — J.  Percy

DR.  HENRY  A.  PILSBRY  IN  FLORIDA 

Dr.  Henry  A.  Pilsbry's  brilliant  pen,  unbelievably  productive 
for  exactly  75  years,  brought  forth  a  vast  source  of  material  of 
particular  interest  to  students  of  Florida  conchology.  Although 
his  many  contributions  covered  land,  marine,  fresh  water  and 
fossil  shells,  his  greatest  interest  was  always  centered  in  the  land 
mollusks.  The  colorful  tree  snails  of  the  genus  Liguus,  confined 
in  Florida  to  the  extreme  lower  mainland  and  the  Keys,  became 
particular  favorites  after  his  review  of  this  group  in  the  ' '  Manual 
of  Conchology,"  published  in  1899  (35).  Feeling  that  much 
remained  to  be  learned  about  the  distribution  of  these  beautiful 
shells,  he  personally  visited  Florida  in  1903  and  made  additional 
collections  to  further  his  studies.  Again,  in  1907,  he  visited 
Florida,  and  together  with  Dr.  Charles  T.  Simpson  made  what 
later  proved  to  be  a  most  memorable  field  trip  to  the  lower 
Florida  Keys.  With  Big  Pine  Key  as  a  base,  a  search  for  tree 
snails  was  made  from  Bahia  Honda  to  Key  West.  The  results  of 
these  findings  were  published  in  his  excellent  work  "A  study  of

vertebrates. ' '— H.B.B.

the  variation  and  zoogeography  of  Ligmis  in  Florida"  (1912, 
14).  This  outstanding  contribution,  together  with  its  superb 
colored  plates,  added  greatly  to  the  knowledge  of  these  lovely 
shells.  Later  he  incorporated  the  work  of  many  Ligmis  enthu- 
siasts and  much  exploration  into  one  volume  to  produce  the  most 
complete  and  finest  work  yet  done  on  the  genus.  This  appeared 
in  1946  in  his  ''Land  Mollusca  of  North  America,"  a  monumental 
work  of  tremendous  importance  which  stands  today  as  a  fitting 
memorial  to  his  great  diligence  and  true  genius. 

In  addition  to  his  outstanding  work  in  the  field  of  land  Mol- 
lusca, Dr.  Pilsbry  made  many  important  contributions  to  all 
other  branches  of  conchology.  Many  sea  shells  were  mono- 
graphed in  his  work  on  the  marine  portion  of  the  "Manual," 
volumes  11  through  17,  which  appeared  from  1889  to  1898.  His 
studies  of  the  Amphineura  (chitons),  which  appeared  in  volumes 
14  and  15,  are  classics  and  a  joy  to  anyone  w^ho  has  ever  used 
them.  He  personally  considered  these  volumes  to  represent 
some  of  his  finest  work.  Numerous  papers  pertaining  to  fresh 
water  mollusks  appeared  in  the  Nautilus  and  other  publications, 
and  in  later  years  he  became  much  interested  in  the  Pliocene 
fauna  of  central  Florida,  at  which  time  he  made  frequent  field 
trips  to  the  vicinity  of  Clewiston  and  Ortona  Locks  where  large 
collections  were  made  for  the  Academy. 

Early  in  1937,  Dr.  Pilsbry  secured  a  cottage  in  Lantana, 
Florida,  and  each  succeeding  winter  visit  to  his  Florida  home 
brought  the  Doctor  new  friends,  plus  a  host  of  notables  in  the 
conchological  world  who  found  their  way  to  his  door.  Frequent 
visitors  were  Dr.  Maxwell  Smith,  Dr.  B.  R.  Bales,  Dr.  Carlos  de 
la  Torre,  Dr.  Jeanne  Schwengel,  Axel  A.  Olsson,  Jay  A.  Weber, 
and  the  writer  with  his  family.  These  winters,  at  home  with 
his  daughters  Elizabeth  and  Grace,  who  acted  as  gracious  and 
able  hostesses  to  assist  in  entertaining  his  many  friends,  were 
certainly  most  happy  ones  for  the  Doctor.  Never  one  to  remain 
idle,  much  valuable  conchological  work  was  accomplished  during 
this  period.  Numerous  field  trips  were  made,  often  with  his 
daughters  assisting  in  the  collecting,  so  that  much  important 
material  was  added  to  the  Academy  collection.  He  visited  Cuba 
for  collecting  with  his  old  friend  Don  Carlos,  and  made  several 
trips  to  St.  Petersburg,  on  the  west  coast  of  Florida,  to  visit 
Mr.  and  Mrs.  Charles  R.  Locklin,  William  G.  Fargo,  Walter  F.

Webb,  Mr.  and  Mrs.  Dan  Steger,  and  many  other  conchologists 
in  that  area.  A  number  of  papers  concerning  Florida  marine 
shells  appeared  at  this  time,  among  them  the  "Vitrinellidae  of 
Florida,"  in  which  the  writer  had  the  privilege  and  pleasure 
of  participation.  This  was  followed  by  Dr.  Pilsbry's  excellent 
work  on  the  fossil  Vitrinellidae  (1953,  8).  During  the  same 
year  another  important  paper  entitled  "Materials  for  a  revision 
of  east  coast  and  Floridan  volutes,"  by  Pilsbry  and  Olsson  (1953, 
6)  made  its  appearance.  The  discovery  of  anatomical  material, 
brought  up  by  deep  sea  dredging  and  formerly  unavailable  to 
students,  permitted  a  revised  generic  classification  of  these  little 
known  Florida  shells. 

During  his  later  years.  Dr.  Pilsbry  spent  at  least  a  portion  of 
his  time  away  from  his  Florida  winter  home  in  order  that  he 
might  visit  his  daughter  Grace  and  her  husband,  Frederick  J. 
Barcroft,  who,  as  a  U.  S.  Foreign  Service  Officer,  was  established 
at  various  posts,  including  Peru,  Argentina  and  Guatemala. 
During  these  visits  to  our  neighboring  countries  to  the  south  Dr. 
Pilsbry  made  many  new  friends,  particularly  in  the  field  of  the 
sciences,  and  did  much  to  spread  a  feeling  of  general  good  will. 
Frequent  collecting  trips  were  arranged  by  Mr.  Barcroft,  and 
the  Doctor,  assisted  by  Elizabeth  and  the  Barcrofts,  again  made 
valuable  additions  to  the  Academy  collection. 

Although  Dr.  Pilsbry  had  an  unusually  long  life,  one  is  amazed 
at  the  vast  amount  of  work  he  accomplished.  Active  to  the 
end,  always  a  prodigious  worker,  he  continued  to  spend  at  least 
a  portion  of  each  year  at  his  desk  in  the  Academy  doing  the 
work  he  so  greatly  enjoyed.  His  regard  and  deep  loyalty  for 
his  beloved  Academy  always  came  first,  but  surely  not  far  behind 
was  his  love  for  the  Nautilus  which  he  served  as  editor  so  faith- 
fully for  so  many  years.     His  guiding  hand  will  be  missed  sorely. 

Dedication  to  his  work,  and  joy  in  its  pursuit  seemed  to  grace 
him  with  a  youthfulness  that  belied  his  years.  His  quick  wit, 
the  happy  twinkle  in  his  eye,  and  the  smooth  rosy  complexion 
which  so  became  him  seemed  to  undergo  no  change  from  70  on- 
ward. Even  at  the  advanced  age  of  90,  he  made  a  dredging 
trip  into  the  Gulf  Stream  in  search  of  deep  sea  specimens. 
Puffing  ardently  upon  his  pipe,  which  incidentally  was  never 
long  extinguished,  one  of  the  last  things  he  told  the  writer  con- 
cerned his  regret  that  illness  had  prevented  completion  of  all 


100  NAUTILUS  [Vol.   71    (3) 

work  planned  for  1957,  but  none  the  less  his  hopes  were  high 
for  a  more  active  and  productive  year  ahead. 

Possessed  of  an  inexhaustible  fund  of  knowledge  embracing 
a  multitude  of  subjects,  he  was  always  a  delightful  person  to  be 
with,  and  those  of  us  privileged  to  have  known  Dr.  Pilsbry  will 
always  remember  his  kindly  manner  and  genial  disposition  which 
invariably  made  friends  at  first  meeting. 

His  many  friends  will  be  pleased  to  know  that  during  his 
final  brief  illness  in  Florida  both  of  his  daughters  were  con- 
stantly at  his  side  offering  love  and  every  comfort,  and  were 
most  solicitous  in  arranging  for  the  best  possible  medical  atten- 
tion at  all  times. — Thomas  L.  McGinty. 


DR.  PILSBRY  AS  A  DRAFTSMAN 

As  artist  at  the  Academy  of  Natural  Sciences  for  a  number  of 
years,  I  have  had  the  great  privilege  of  illustrating  some  of 
Dr.  Pilsbry 's  many  writings.  He  was  always  most  kind  and 
encouraging  during  the  years  of  my  association  with  him,  espe- 
cially when  I  was  timidly  starting  out  on  a  career  as  an  artist. 
So,  I  am  glad  to  have  this  opportunity  of  expressing  my  appre- 
ciation of  his  technical  as  well  as  artistic  ability. 

As  is  probably  well  known.  Dr.  Pilsbry  made  numerous  draw- 
ings himself,  especially  for  the  Nautilus,  because  he  was  not 
allowed  to  take  the  artist's  time.  He  also  did  more  than  one 
plate  of  colored  figures  for  other  publications,  which  he  seemed 
to  enjoy  doing,  and  took  great  satisfaction  in  their  accomplish- 
ment.    We  used  India  ink  'Svash"  for  half  tones. 

He  had  the  advantage  over  other  artists  in  that  he  knew  at 
first  glance  the  salient  points  he  wished  to  bring  out  in  any 
illustration.  While  I  was  still  at  the  Academy,  he  began  to 
assemble  all  his  drawings ;  there  must  have  been  hundreds  of 
them. — Helen  Winchester  Gapp. 


FROM  THE  PILSBRY  CHAIR  OF  MALACOLOGY 

As  I  join  others  in  their  praise  of  Dr.  Henry  A.  Pilsbry 's 
outstanding  scientific  accomplishments  and  express  my  own  per-

sonal  loss  of  a  kindly  mentor,  I  would  like  to  record  Dr.  Pilsbry's 
contributions  to  the  development  of  the  Department  of  Mollusks 
at  the  Academy.  No  man  can  serve  at  the  helm  of  a  museum 
department  for  69  years  without  profoundly  influencing  the 
growth  of  its  collections  and  the  makings  of  its  success. 

Pilsbry  was  25  years  old,  and  had  been  at  the  Academy  for 
only  three  months,  when  he  was  made  Conservator  of  the  mollusk 
collection  on  February  28,  1888.  Consider  the  conditions  and 
circumstances  at  that  time.  The  eminent  George  W.  Tryon,  Jr., 
Conservator,  founder  and  "spark  plug"  of  the  Conchological 
Section,  had  suddenly  died  at  the  age  of  50.  The  well-known 
and  financially  successful  "Manual  of  Conchology"  was  in  its 
10th  volume ;  the  Section  was  highly  organized  with  a  half-dozen 
well-to-do  officers,  over  a  hundred  subscribing  members,  and 
several  committees  of  volunteer  workers;  it  was  conceded  that 
the  collection  contained  more  species  and  specimens  than  any 
other  in  the  Western  Hemisphere. 

This  was  the  bright  side  of  the  picture,  and  to  a  young  and 
inexperienced  man  of  less  ability  than  Pilsbry 's,  this  would  have 
been  an  over-powering  responsibility  and  a  frightening  reputa- 
tion to  uphold.  To  the  new  Conservator,  the  bleak  side  was 
even  more  evident.  The  growing  collection  was  becoming  ser- 
iously overcrowded.  It  was  almost  entirely  uncatalogued  and 
was  housed  in  ill-suited  exhibit  cases  on  the  galleries  surrounding 
the  library  hall  of  the  Academy.  The  "officers  of  the  Section 
were  pressing  for  an  immediate  continuation  of  the  "Manual," 
and  had  arranged  that  most  of  Pilsbry's  salary  would  consist 
of  50  percent  of  the  profits  from  its  sale.  Most  of  the  men 
supporting  the  section  were  a  full  generation  older  than  Pilsbry 
and  had,  for  years,  been  led  by  Tryon 's  dynamic  and  persuasive 
personality.  Although  sympathetic  men  like  S.  Raymond  Rob- 
erts, the  treasurer  of  the  Section  and  the  Academy,  and  John 
Campbell,  an  amateur  conchologist,  put  justified  faith  in  the 
talented  new  man,  it  was  natural  that  some  of  Tryon 's  friends, 
contacts  and  activities  would  fade  from  the  scene.  Tryon 's 
dynasty  was  coming  to  an  end.     The  Pilsbry  era  was  being  born. 

Pilsbry  plunged  himself  into  his  new  job  with  fervor.  The 
next  volume  of  the  Manual  met  its  deadline.  After  a  year,  he 
joined  forces  with  Averell,  a  local  shell  dealer,  and  revived  the 
" Conchologist 's  Exchange"  into  the  successful  and  productive 


102  NAUTILUS  [Vol.   71    (3) 

journal,  the  Nautilus.  In  addition  to  taking  care  of  the  col- 
lection, he  gave  formal  lectures  on  mollusks  to  members  of  the 
Academy.  From  his  accounts  in  the  annual  reports,  evidently 
the  physical  condition  of  the  collection  continually  worried 
Pilsbry.  His  almost  full-time  preoccupation  with  publishing 
research  merely  aggravated  the  situation. 

Pilsbry  was  motivated  by  two  impelling  desires  which  are 
ingrained  in  all  good  museum  men  and  which  overshadowed  all 
other  considerations:  production  of  publications  and  acquisition 
of  new  material.  His  field  work,  correspondence,  personal  al- 
liances and  development  of  projects  were  all  bent  in  these  two 
directions.  Almost  yearly,  he  added  to  his  annual  reports  a 
note  that  ''the  great  number  of  species  and  types  contained  in 
the  collection  of  the  Academy  imposes  a  large  amount  of  corre- 
spondence upon  the  Conservator,  and  no  little  time  is  consumed 
in  the  comparison  of  specimens  for  correspondents.  This  labor 
is  amply  repaid,  however,  by  the  large  mass  of  new  material 
which  it  secures  us,  and  which  could  be  obtained  by  no  other 
means."  From  the  start,  Pilsbry  was  quick  to  profit  from  the 
generous  fund  left  by  Tryon  for  the  purchase  of  shells.  Valu- 
able new  material  was  obtained  from  Fulton  and  Sowerby, 
Morelet,  Moellendorff,  J.  C.  Cox,  Henry  Suter  and  others. 

By  1900,  Pilsbry,  at  the  age  of  38,  had  proved  himself  to  be 
far  superior  as  a  research  man  than  Tryon.  The  mountain  was 
now  coming  to  Mohammed.  Hirase,  Ferriss,  A.  P.  Brown, 
Frederick  Stearns  and  others  were  bearing  gifts  of  priceless 
material  in  return  for  junior  authorship  with  a  leader  in  the 
field.  While  the  venerable  William  H.  Dall  in  Washington  was 
cutting  a  wide  swath  in  marine  mollusks,  Pilsbry  was  concentrat- 
ing on  a  vacant  niche  that  was  dear  to  his  heart,  the  land 
mollusks.  As  the  years  passed,  the  Academy's  collection  swelled 
with  Pilsbry 's  types  in  new  land,  fresh-water  and  marine  species. 
Editorship  of  the  Nautilus  afforded  an  opportunity  for  many 
unique  acquisitions.  His  several  expeditions  further  increased 
the  collection  upon  which  he  could  compose  his  research  tunes. 
During  his  tenure  as  Curator,  the  collection  was  increased  by 
nearly  130,000  lots  or  trays,  about  4000  of  which  were  primary 
types.

By  the  time  Dr.  Pilsbry  was  in  his  late  eighties,  and  even 
though  he  was  still  very  active,  both  physically  and  mentally, 
he  and  his  close  friends  began  to  consider  the  problem  of  a 
successor.  An  old  problem  common  to  most  museums  of  natural 
history  threatened  the  future  of  the  Department.  As  the  cost 
of  living  rises,  even  doubles,  over  the  years,  allotted  budgets  and 
salaries  change  very  little.  Dr.  Pilsbry  was  aware  of  the  dim 
prospects. 

His  friends  rallied  to  the  cause.  What  better  way  to  pay 
tribute  to  the  master  and  assure  the  continued  success  of  the 
Department  than  by  creating  and  financing  a  research  chair  in 
his  name?  In  October  1954,  a  small  fund  was  established  for 
the  formation  of  the  Henry  A.  Pilsbry  Chair  of  Malacology. 
The  initial  boost  came  from  Mr.  Alfred  J.  Ostheimer,  3rd,  of 
Whitford,  Pa.  and  Miss  Anne  Harbison  of  Philadelphia.  Other 
friends  and  admirers  joined  in  supporting  the  fund,  and  within 
two  years  about  two  dozen  contributors  had  brought  the  amount 
up  to  half  of  the  $200,000  goal.  Although  the  fund  is  still  far 
short  of  its  goal,  the  fact  that  the  position  was  filled  was  a 
great  satisfaction  to  Dr.  Pilsbry.  Many  of  the  irksome  details 
of  departmental  administration  and  ''fund-grubbing"  were 
lifted  from  his  shoulders,  thus  permitting  him  uninterrupted 
time  for  his  research. 

It  is  sometimes  difficult  for  an  elderly  emperor  to  slacken  the 
reins  of  control,  but  Dr.  Pilsbry  guided  the  new  man  with 
patience,  understanding  and  grace.  Although  some  of  the  in- 
evitable innovations  must  not  always  have  secretly  pleased  him, 
he  never  once  expressed  disapproval.  He  knew  that  the  same 
problems  that  faced  him  as  a  young  man  were  again  being  tackled 
by  a  new  generation.  He  left  for  Florida  in  October,  1957,  with 
plans  for  another  winter  of  quiet  research,  content  in  the  knowl- 
edge that  the  museum  ''home  fires"  were  still  burning  cheerfully 
in  his  absence.  Once  again,  the  wheel  of  time  turned  its  full 
revolution  on  another  generation.  The  Pilsbry  era  was  coming 
to  a  close,  but  leaving  one  of  the  most  striking  and  glorious 
chapters  in  the  history  of  the  Department  of  Mollusks  at  the 
Academy. — R.  Tucker  Abbott,  Academy  of  Natural  Sciences  of

SCIENTIFIC   CONTRIBUTIONS   MADE   FROM 

1940  TO  1957 
By  HENEY  a.  PILSBRY 

In  1940,  the  American  Malacological  Union  published  a  chro- 
nologic list  of  the  "Scientific  contributions"  of  H.  A.  Pilsbry,  up 
to  and  including  1939.  This  was  not  a  complete  bibliography, 
but  purposely  omitted  most  obituaries,  editorials  without  perti- 
nent scientific  content  and  all  reviews  (except  the  very  few  with 
new  names),  whether  initialed  or  unsigned.  If  the  custom  of 
the  "Zoological  Record"  had  been  followed,  the  unsigned  publi- 
cations in  the  Nautilus  would  have  been  ascribed  to  the  editors, 
as  for  example:  [H.  A.  Pilsbry  &  C.  W.  Johnson].  Recently, 
a  random  count  of  these  omissions  was  made  in  two  volumes,  17 
and  18.  Of  the  editorials  and  obituaries,  mainly  unsigned,  15 
were  found,  of  the  reviews,  mainly  initialed,  30.  If  one  multi- 
plies this  by  34  (half  68  volumes),  one  arrives  at  an  estimated 
total  of  1530,  which  may  mean  that  more  than  half  the  notes 
in  the  Nautilus,  which  probably  were  composed  by  Pilsbry,  at 
least  as  senior  author,  were  omitted.  Since  he  was  a  reporter 
when  young,  signed  the  yearly  reports  of  his  section  and  de- 
partment (Proe.  ANSP.)  and  although  he  wrote  nothing  for 
"Biological  Abstracts,"  an  estimate  between  3000  and  4000 
possibly  might  cover  the  number  of  published  articles  that 
flowed  from  his  facile  pen.  (Numbers  do  depend  on  who  counts 
them.) 

Number  1  of  the  1940  publications  is  included  partly  because 
the  biography  on  pages  one  to  three  was  written  out  by  Dr. 
Pilsbry,  and  his  phraseology  largely  was  retained,  although  of 
course  all  the  encomiums  and  some  of  the  data  were  interpolated 
by  the  A.  M.  U.  editors.  Also  the  list  of  publications  was  based 
on  one  he  had  for  his  own  use,  several  years  before,  so  that  the 
plan  of  omissions  was  based  on  his  judgment,  except  where  the 
A.  M.  U.  editors  were  less  severe.  For  example,  he  omitted  all 
excerpts  from  another  man's  publications,  like  those  in  1900, 
no.  18. 

The  following  pages,  which  attempt  to  bring  his  "Scientific 
contributions"  up  to  date,  do  include  signed  and  unsigned 
fP&B.|  obituaries  and  death  notices  and  also  initialed  editorials 
in  the  Nautilus,  but  omit  brief  remarks  in  "Notes  and  News."

THE  PILSBRY  NAUTILUS 

When  only  26  years  of  age,  Henry  A.  Pilsbry  began  the 
Nautilus  on  May  5,  1889,  with  volume  3,  because  it  succeeded 
(N.3:l)  the  "Conchologist's  Exchange,"  after  a  year's  lapse. 
At  first,  it  was  a  monthly  ^  at  $1.00  a  year  for  144  pages  plus 
covers  and  plates.     His  one  year's  association  with  William  D. 

1  Rarely  double  numbers  (so  marked)  were  issued  and  vol.  23  had  only 
11,  although  with  the  full  number  of  pages. 


January,  1958]  nautilus  113 

Averell  (1853-1928;  N.42:33)  as  its  business  manager  (see 
latter 's  ''Prospectus")  was  none  too  happy  and,  at  the  end  of 
one  volume  (N.4:l),  Averell  was  replaced  by  another  Phila- 
delphian,  at  the  Wagner  Free  Institute  of  Science :  Charles  W. 
Johnson,  who  was  not  quite  a  year  younger  than  Pilsbry,  and 
who  became  junior  editor  and  manager.  Undoubtedly  young 
Johnson  (N.l:vii  of  index)  and  probably  Pilsbry  expected  some 
cash  profit  from  their  partnership.  Since  Americans  tradi- 
tionally have  regarded  basic  (not  immediately  practical)  scien- 
tific studies  as  luxuries  rather  than  necessities,  such  hopes 
crashed  abruptly  during  the  "hard  times"  around  1893  (N. 
7:25).  During  the  next  4  years,  they  often  feared  that  they 
could  not  carry  the  deficits  (N.9:97;  N.10:97)  out  of  their 
moderate  earnings,  until  support  was  guaranteed  by  Bryant 
Walker  and  others  (N.ll:12). 

When  Johnson  (at  40)  went  to  the  Boston  Society  of  Natural 
History,  the  Nautilus  was  issued  at  Boston  (N.17:l)  from 
volume  17  (May,  1903)  until  his  death  (N.46:37)  at  68,^  4  days 
before  the  mailing  of  the  July  number  by  his  Boston  colleagues. 
Throughout  the  42  years  of  the  Pilsbry-Johnson  partnership 
(and  afterwards),  the  publication  was  carried  on  as  a  ''labor 
of  love"  by  two  busy  scientists,  without  salaries,  endowments 
or  dividends,  except  a  small  one  in  the  early  1900s,  which  may 
have  recompensed  them  in  part  for  their  earlier  losses. 

In  1914,  with  volume  28  (N.27:144)  the  annual  price  was 
advanced  to  $1.50;  3  years  later  (N.30:144),  subscriptions  be- 
came $2.00,  and  the  Nautilus  changed  to  a  quarterly  (36  text 
pp.  per  no.)  with  the  first  (July,  1917)  number  of  volume  31. 
During  the  older  World  War,  most  foreign  subscribers  were  lost, 
and  some  financial  difficulties  followed  (N.34 :36 ;  36 :72 ;  38  :108) . 
Because  of  postal  laws,  the  title  pages  and  indexes  of  volumes 
43  to  45  were  added  as  the  last  4  pages  of  their  April  numbers ; 
previously,  from  volumes  3  to  42,  they  had  been  stapled 
separately. 

Dr.  Pilsbry  (then  69)  thought  that  both  editors  should  be 
in  the  same  city;  so  my  association,  as  junior  editor  and  man- 
ager, began  with  the  October,  1932,  number  (p.  37)  and  Phila- 

2  Coincidentally,  Dr.  Pilsbry  died  on  the  94tli  anniversary  of  his  partner 's 
birth. 


114  NAUTILUS  [Vol.   71    (3) 

delphia  again  became  the  post  office  of  issue.  Beginning  with 
vol.  46,  the  removal  of  title  pages  and  indexes  was  made  easier 
by  their  inclusion  in  the  middle  of  each  April  number  (except 
those  for  vols.  54  &  55,  which  were  stapled  in  vol.  55,  no.  1,  and 
vol.  56,  no.  2,  respectively).  The  present  practice  of  volume, 
number,  month  and  year  at  the  tops  of  opposing  pages  began 
with  vol.  48,  no.  1.  The  dates  for  each  volume  have  been  in- 
cluded under  ''Notes  and  News,"  usually  in  the  next  July 
number,  since  vol.  46,  no.  2  (N. 48:69).  Earlier  dates  are  in 
''Scientific  contributions"  (1940,  1). 

After  the  1929  "depression,"  many  subscribers  again  de- 
serted, and  rather  severe  deficits  once  more  became  the  rule. 
During  the  last  World  War,  almost  all  foreign  subscriptions 
stopped,  but  this  largely  was  counterbalanced  by  increases  in 
U.  S.  subscribers,  when  money  became  easier.  But  another  dif- 
ficulty appeared.  Partly  because  of  paper  rationing  during  the 
war,  but  mainly  on  account  of  renewed  and  retroactive  subscrip- 
tions, the  reserve  stocks  of  vols.  52  to  58  rapidly  diminished. 
Apparently  a  similar  expansion  came  10  years  after  1893,  since 
the  stocks  of  vols.  17  to  24  are  quite  exhausted.  Let  future 
managers  beware,  because  a  sale  of  back  numbers  often  has 
abolished  a  bad  deficit ! 

Due  to  inflation,  the  subscription  price  necessarily  has  been 
raised  three  times  in  eight  years:  to  $2.50  with  vol.  63  (N. 
62:145),  to  $3.00  with  vol.  67  (N.66:108)  and  to  $3.50  with 
vol.  71  (N.70,  no.  3,  p.  iii).  Because  of  the  lapse  of  6  months 
between  each  increase  in  printing  costs  near  the  first  of  a  year 
and  the  beginning  of  the  next  volume  with  a  July  number, 
minor  deficits  also  bothered,  especially  in  1949  and  1953,  but 
the  Nautilus  again  is  making  debits  and  credits  meet. 

When  an  estimate  was  made  a  few  years  ago,  almost  half  of 
the  subscribers  were  amateur  hobbyists,  whose  subscriptions  do 
tend  to  rise  and  fall  with  the  times,  and  we  always  have  tried 
to  include  some  papers  in  each  number  for  them.  But,  the 
backbone  of  the  Nautilus,  that  kept  it  going  when  money  be- 
came scarce,  apparently  always  has  been  the  more  continuous 
subscriptions  of  institutions  and  of  professional  zoologists  and/or 
malacologists.  For  this  reason,  if  for  no  other,  the  scientific 
standards,  established  by  Dr.  Pilsbry  during  his  68  years  as 
senior  editor,  must  and  shall  be  maintained. 


January,  1958]  nautilus  115 

At  least  twice  during  September  and  October,  1957,  Dr. 
Pilsbry  implored  me  to  make  sure  that  the  Nautilus  would 
continue,  and  solemnly  was  promised  that  it  would.  The  present 
plans  are  that  Dr.  Charles  B.  Wurtz,  Consulting  Biologists, 
610  Commercial  Trust  Building,  Philadelphia  2,  and  Dr.  R. 
Tucker  Abbott  (Pilsbry  Chair  of  Malacology),  Academy  of 
Natural  Sciences,  19th  and  the  Parkway,  Philadelphia  3,  will 
join  the  staff  as  junior  editors  with  the  understanding  that, 
if  at  any  future  time  either  should  cease  to  be  a  resident  of 
the  Philadelphia  area,  this  would  be  considered  as  a  tendered 
resignation. 

Dr.  Abbott  will  edit  especially  papers  on  marine  mollusks. 
Dr.  Wurtz  will  continue  to  superintend  the  mailing  of  back 
numbers,  take  over  the  actual  mailing  of  each  issue,  and  become 
editor  for  fresh  water  mollusks  and  ecology.  Bernadine  B. 
Baker  (Mrs.  Horace  B.  B.),  11  Chelten  Road,  Havertown,  Pa., 
as  manager,  will  keep  the  books  and  receive  renewals,  new 
subscriptions  and  orders  for  back  numbers.  Since  the  Bakers 
and  the  Nautilus  can  afford  but  one  bank  account,  checks  may 
be  made  out  as  usual. 

jManuscripts,  for  publication  in  the  Pilsbry  Nautilus,  should 
be  sent  to  the  senior  editor,  as  customarily  stated  on  page  ii 
(inside  of  back  cover).  He  has  on  file  all  those  at  the  ANSP. 
or  acknowledged  by  him.  Publication  of  these  may  be  a  bit 
slow  for  a  while,  since  enough  are  on  hand  for  two  future 
numbers,  but  this  rarely  has  continued  to  be  the  case  for  long. 

Two  general  indexes  have  been  issued  by  others.  The  ''Index 
to  the  Nautilus,  vols.  3  to  34,  1889-1921  and  to  its  predecessor  ^ 
the  Conchologist 's  Exchange,  vol.  1,  2,  1886-1888,"  was  com- 
piled by  John  Brooks  Henderson,  Jr.  (Frontispiece;  died  1923) 
assisted  by  Marguerite  Woodward,  and  edited  by  William  H. 
Dall.  It  was  published  in  1927  by  George  H.  Clapp  and  Bryant 
Walker.  About  1933,  its  two  owners  generously  presented  the 
remaining  copies  to  the  Nautilus  and  these  still  furnish  some 
support.  The  "Index  to  the  Nautilus,  volumes  35  to  60,  1921- 
1947,"  was  compiled  by  Aurele  LaRocque,  assisted  by  Geneva 
Smithe  and  Harold  W.  Harry;  it  was  published  in  1951,  and 
is  sold  by  the  University  of  Michigan  Press. — H.  Burrington

NOTES  AND  NEWS 

Type  of  Paludestrixa. — Paludestrina  Orbigny,  1839  or  1840, 
Voy.  Amer.  Merid.  (Moll.),  p.  381,  evidently  was  proposed  to 
replace  Ilydrohia  Hartmann,  1821,  type  Helix  acuta  Miiller, 
1774,  Verm.  II,  p.  100.  Although  the  word  ''substitute"  was 
not  used,  Paludestrina  at  least  included  Hydrohia.  Apparently 
the  first  valid  type  selection  was  made  by  Bourguignat,  1887, 
Etud.  petit.  Paludinidees,  p.  10,  who  designated  H.  acuta  =  P.  a. 
Dr.  von  Ihering's  subsequent  and  invalid  type  selection,  1895, 
Nachrbl.  Deutsch.  Malak.  Ges.  27:128  (Cf.  N.10:119),  was 
useless,  as  our  old  South  American  friend  (1850-1930)  and 
correspondent  must  have  realized  before  1910  (N.24:15). 
Equally  unnecessary  was  Parodiz's  attempt,  1955,  Neotropica 
1 :95-96,  to  replace  Potamolithus,  1896,  by  Paludestrina,  which 
last  remains  what  Orbigny  intended  it  to  be :  an  objective 
synonym  of  Hydrohia.  ' ^ Reqiiiescant  in  pace^'  for  another  60

Collecting  in  Peru  and  Argentina. — A  collecting  trip  was 
always  my  father's  greatest  pleasure  and  recreation.  A  great 
outdoors  man,  he  was  comfortable  in  any  circumstances  and 
equal  to  all  situations.  In  Peru,  we  with  others  made  long  trips 
over  much  wildly  beautiful  country,  besides  short  ones  around 
Lima.  All  were  successful;  he  always  knew  where  the  shells 
were. 

Dr.  Jorge  A.  Broggi  took  us  on  many  delightful  collecting 
trips,  especially  a  five  day  one  to  Paracas  and  Pisco  in  southern 
Peru,  over  the  deserts.  Axel  Olsson  took  us  on  a  fine  camping 
trip  from  Talara  to  Zorritos  and  Tumbes  in  northern  Peru. 
In  1948,  Dr.  Pennell  joined  us  in  one  to  the  mountains  east  of 
Trujillo  and  another  to  Cajamarca,  from  where  we  went  to 
Celendin  and  down  into  the  canyon  of  the  Maranon.  Other 
trips  took  us  to  Tingo  Maria,  Cusco,  Chimbote  and  up  the 
canyon  of  the  Santa  River,  and  Machupicchu.  We  crossed  the 
continental  divide  five  times;  my  father  was  not  affected  by 
the  altitude. 

He  was  not  affected  by  the  heat  either.  In  1950  on  the 
pampas  of  Argentina,  he  enjoyed  the  oven  birds  and  burrowing

owls,  oblivious  to  110  degrees.  We  again  were  visiting  Grace 
and  Fred,  whose  home  was  near  Rio  de  La  Plata,  in  which  he 
collected  at  low  tide.  Together  we  collected  up  the  coast  of 
Uruguay  to  the  Brazilian  border,  and  also  at  the  falls  of  Iguazu, 
near  the  Paraguay  border.  Father  also  enjoyed  the  warm 
hospitality  of  Dr.  Biraben  and  his  wife,  Dr.  Hylton  Scott. 

Good  trips  in  Guatemala  were  planned  for  1957-8,  but  my 
father's  heart  attack  suggested  a  switch  to  a  quiet  winter  in 
Florida,  which  was  cut  short  by  his  untimely  death.  Of  Father, 
at  nearly  95,  one  truly  may  say:  '^He  died  young." — Elizabeth

Resolutions. — We  have  learned  with  great  sorrow  of  the 
death  of  our  distinguished  Honorary  Life  President,  Doctor 
Henry  Augustus  Pilsbry,  Curator  of  Mollusks  at  the  Academy 
of  Natural  Sciences.  In  grateful  tribute  to  his  memory,  we 
recognize,  as  the  world  of  science  already  has  recognized,  the 
conspicuous  abilities  displayed  by  him  in  the  fields  of  Mollusca 
and  Cirripedia,  but  still  more  fully  we  appreciate  the  fact  that, 
as  a  contributor  of  a  vast  amount  of  basic  research,  he  stood 
without  a  peer.  His  judgment  and  scientific  conclusions  will 
guide  many  generations  to  come.  His  leadership  and  helping 
hand  kept  alive  the  greatness  of  the  Academy  and  served  as  an 
inspiration  in  the  founding  of  this  Club.  We  mourn  his  loss  not 
only  on  account  of  these  attainments,  but  also  as  a  man  of  broad 
sympathies,  cheerful  character  and  tender  heart.  Our  sincere 
sympathies  are  extended  to  the  members  of  his  bereaved  family, 
with  a  token  copy  of  these  resolutions. — Philadelphia  Shell 
Club.

THE  NAUTILUS 

Vol.  71  APRIL,   1958  No.  4 


REDISCOVERY  OF  A  RARE  CARIBBEAN  CONUS 

By  R.  tucker  ABBOTT 

Pilsbry  Chair  of  Malacology 

Mrs.  Mildred  R.  Barnes  sent  me  three  specimens  of  a  rare  and 
hitherto  misunderstood  species  of  Conus,  that  she  collected  in 
July  1956  on  the  beach  just  east  of  Boca  Mahos,  Aruba  Island, 
Netherlands  Antilles.  They  are  Conus  armillatus  C.  B.  Adams, 
previously  reported  only  from  Jamaica  and  the  Virgin  Islands, 
and  a  species  formerly  relegated  to  the  synonymy  of  other  species 
of  Conus. 

In  1942,  Clench  (Johnsonia,  vol.  1,  no.  6,  p.  3)  considered  it 
to  be  a  young  specimen  of  C.  regius  Gmelin.  In  1950,  Clench 
and  Turner  (Occ.  Papers  on  Moll.,  Harvard,  vol.  1,  no.  15,  p. 
258,  pi.  31,  fig.  10)  repeated  this  opinion.  They  figured  the  sup- 
posed holotype,  although  that  shell,  according  to  the  magnifica- 
tion given  in  the  explanation  of  plates,  is  almost  twice  the  size 
of  that  from  which  Adams  made  his  description.  I  believe  Adams 
probably  had  several  shells,  but  only  one  badly  worn  specimen 
(possibly  a  young  shell  of  regius)  remained  in  his  collection  when 
Clench  and  Turner  chose  the  holotype.  In  1875,  WeinkaufF  (Syst. 
Conchyl.  Cab.,  vol.  4,  pt.  2,  p.  392)  considered  armillatus  a  syno- 
nym of  C.  proteus  Hwass  =:  C.  spurius  Hwass  on  the  basis  of  a 
probably  misidentified  specimen  in  Dunker's  collection.  In  1864, 
Krebs  (The  West  Indian  Marine  Shells,  p.  3) ,  suggested,  in  error 
I  believe,  that  this  species  was  C.  mindanus  Hwass  from  the 
Philippines. 

Below  is  given  a  full  description,  which  has  so  many  important 
features  mentioned  by  Adams  that  I  have  little  hesitation  in  as- 
suming that  these  specimens  from  Mrs.  Barnes  are  C.  armillatus. 

Shell  13  to  17  mm.  in  length,  solid,  and  ovate-conic.  Whorls  7, 
rounded  at  the  shoulder,  slightly  convex  on  the  sides,  and  flattish 
at  the  base.  Whorls  in  spire  convex.  Ground  color  milk-white, 
overlaid  with  irregular  dark-brown  mottlings  which  may  consist 
of  squarish  or  oblong  splotches  at  times  becoming  axially  con-

118  NAUTILUS  Vol.   71     (4) 

fluent.  Color  of  spire  white  with  narrow,  zigzag  axial  bars  of 
black-brown.  Interior  of  aperture  purple-brown  with  a  revolving, 
narrow  white  band  just  below  the  middle.  Base  of  shell,  inside 
and  out,  a  pale  lavender  or  brownish  lavender.  Nuclear  whorls 
whitish  tan.  Spiral  sculpture  on  the  spire  consists  of  about  6  fine, 
raised  threads;  on  the  body  whorl  there  are  about  20  very  narrow, 
raised,  whitish  threads  bearing  a  series  of  tiny  rounded  beads; 
towards  the  base  the  threads  become  more  grossly  pustulous,  but 
on  the  fasciole  they  are  obsolete.  The  scar  caused  by  the  posterior 
siphonal  filament,  located  on  the  parietal  wall  at  the  top  of  the 
aperture,  is  deep  and  channel-like.  Length  and  width  of  3  speci- 
mens, respectively,  are:  16.5  X  9.4;  15.3  X  8.5;  and  13.0  x  7.5  mm. 

Comparative  remarks:  C.  armillatiis  is  recognized  by  its  laven- 
der base,  and  non-coronate  spire.  C.  armillatus  resembles  C. 
jaspideus  Gmelin  in  size  and  shape,  but  has  fine  spiral  threads 
on  the  top  of  the  whorls  in  the  spire  and  has  a  lavender  base. 
It  differs  from  regius  in  not  having  a  coronate  spire.  Superficially, 
the  color  and  shape  of  this  cone  suggests  a  darkly  colored,  im- 
mature specimen  of  Columbella   mercatoria    (L)  . 

Mrs.  Barnes  also  obtained  at  Aruba  one  of  the  smallest  speci- 
mens of  Strombus  gallus  L.  on  record  (an  adult  70  mm.  in 
length) ,  and  two  cones  which  appear  to  be  Conus  sennottorum 
Rehder  and  Abbott,   1951. 


ELLOBIID  AND  OTHER  ECOLOGY  IN  FLORIDA 

By  J.  P.  E.  MORRISON 

In  the  course  of  a  two  weeks'  visit  to  the  Miami  region  in  No- 
vember 1955,  a  special  search  was  made  for  the  species  of  salt- 
marsh  snails  (Ellobiidae)  living  there  and  on  the  Florida  Keys. 
This  search  proved  so  successful  that  the  ecological  observations 
are  offered  here  in  the  belief  that  at  least  some  of  this  data  may 
be  new  to  others  also.  They  should  be  helpful  in  collecting  the 
species  more  readily,  as  well  as  in  understanding  these  species 
and  their  biology.  Knowledge  of  the  habitats  is  necessary  even  to 
find  some  of  the  smaller  forms  which  live  only  under  rocks  along 
some  of  the  Florida  shorelines. 

At  Matheson  Hammock  Park,  the  small  black  Batillaria  min- 
ima (Gmelin)  was  abundant  in  countless  numbers  everywhere 
on  the  coralline  rocks  along  the  shore.  Nassarius  vibex   (Say)  was 


April,  1958  nautilus  119 

found  in  one  to  three  feet  of  water  in  the  sandy  bottom  at  the 
swimming  beach.  A  walk  (barefooted,  and  carrying  a  small  grand- 
son on  one  arm)  on  the  coralline  gravel  surface  of  the  rock  jetty 
that  surrounds  and  protects  this  swimming  beach  was  somewhat 
painful.  Search  here  under  some  rotting  coconut  husks  in  the 
drift  piled  along  the  high  tide  line  on  the  outer  side  of  the  jetty 
yielded  a  few  live  specimens  of  Pira  monile  (Bruguiere)  as  a 
reward.  Also,  there  were  a  few  Tectarius  muricatus  (Linn^)  in 
the  crevices  of  the  coralline  rocks  just  a  little  above  the  high 
tide  line. 

Travelling  southward  a  mile  or  so  to  Snapper  Creek,  by  out- 
board motor  boat,  we  went  a  mile  up  the  creek  to  get  into  the 
landward  part  of  the  Mangrove  swamps.  A  small  inlet  cut  into 
the  swamp  on  the  north  side  of  Snapper  Creek  was  barren  of 
shells,  but  at  a  distance  of  25  feet  or  so  from  this  inlet,  the  ex- 
pected Melampus  population  was  found.  These  Melampus  coffeus 
(Linne)  were  quite  active,  crawling  all  over  the  mud  of  the 
swamp,  in  the  shade  of  the  mangroves,  when  the  tide  was  low. 
More  than  200  were  picked  up  in  just  a  few  minutes.  Care  taken 
to  completely  sample  the  population  by  collecting  every  specimen 
in  a  limited  area,  including  all  the  small  shells,  paid  oft.  When 
these  shells  were  studied  later,  it  was  discovered  that  Detracia 
clarki  Morrison  is  living  here  in  small  numbers  with  M.  coffeus. 
The  15  specimens  of  cLarki  collected  here  looked  just  like  the 
small  M.  coffeus  when  they  were  all  mud-coated  and  crawling 
on  the  mud  surface  together. 

A  check  of  the  mangrove  swamp  just  behind  the  sand  barrier 
at  the  mouth  of  Snapper  Creek  revealed  Melampus  thriving  here 
also.  In  this  part  of  the  swamp,  only  4  specimens  of  Melampus 
bideniatus  Say  and  6  specimens  of  Detracia  clarki  were  picked 
up  with  more  than  200  of  Melampus  coffeus  in  a  short  time. 
Under  the  logs  and  other  drift  at  the  high  tide  line  on  the  Bis- 
cayne  Bay  side  of  the  sand  beach  barrier  were  found  a  couple  of 
mature  specimens  of  Detracia  bullaoides  (Montagu),  in  com- 
pany with  numerous  Truncatella  pulchella  Pfeiffer  and  T.  cari- 
baeensis  Reeve. 

On  the  return  from  a  sight-seeing  trip  to  Key  West,  a  stop  was 
made  for  swimming  at  Bahia  Honda  Key.  While  the  family,  in- 
cluding the  grandsons,  went  swimming  at  the  beach  on  the  north 


120  NAUTILUS  Vol.   71     (4) 

side  of  Bahia  Honda,  I  stru|2^gled  a  few  yards  into  the  mangrove 
swamp  just  east  of  the  parking  lot,  and  fought  off  mosquitoes 
and  blackflies  for  about  a  half  hour.  Melampus  were  not  too 
abundant  here,  but  were  seen  sparingly  on  the  mud,  or  on  the 
lower  parts  of  the  mangroves.  Only  one  large  Melampus  coffeus 
was  found  living  here.  A  mixture  of  M.  hidentatus  (41  speci- 
mens) and  of  Detracia  clarki  (26  specimens)  made  up  the  rest 
of  this  sample.  Before  the  tide  came  in  too  far,  a  dozen  and  a 
half  of  the  tiny  Cerithidea  costata  (DaCosta)  were  seen  crawling 
on  the  mud  and  the  fallen  mangrove  leaves.  They  were  not  abun- 
dant here,  perhaps  only  one  or  two  every  square  yard,  in  this 
landward  margin  of  the  mangroves.  The  incoming  tide  also  pre- 
vented the  discovery  of  the  exact  habitat  in  which  the  brackish- 
water  clam  Pseudocyrena  maritima  (Orbigny)  lives  in  this 
swamp.  Only  a  couple  of  recently  dead,  empty  shells  of  the 
Pseudocyrena  were  collected. 

On  the  north  side  of  the  small  boat  channel  at  the  northeast 
corner  of  the  parking  lot,  the  shore  is  open,  rocky,  with  a  few 
small  mangrove  saplings  beginning  to  take  hold.  Under  the 
small  rocks  (coralline  limestone)  just  below  the  high  tide  line, 
live  three  minute  species  of  Ellobiids,  along  with  the  tiny  golden 
snail  Syncera.  On  the  under  side  of  these  rocks,  the  tiny  specks 
of  dark  reddish  brown  color  proved  to  be  Pedipes  ovalis  (C.  B. 
Adams) ,  and  Syncera  modesta  (H.  C.  Lea)  ;  those  of  paler  color 
were  mostly  Laemodonta  cubensis  (Pfeiffer) ,  with  two  specimens 
of  Marinula  succinea  (Pfeiffer) .  One  fine  specimen  of  Siphonaria 
alternata    (Say)    was  found  on  one  of  the  rocks  here  also. 

A  three-day  stay  on  Plantation  Key  was  especially  valuable  in 
allowing  time  to  look  for  some  of  the  less  obvious  species.  The 
north  side  of  the  Key,  just  east  of  the  Plantation  Harbor  Yacht 
Club  pier,  is  a  secondary  habitat,  rather  than  a  completely 
natural  one.  It  has  been  filled,  with  a  shore  line  stabilized  by 
a  low  concrete  wall  in  part,  and  with  the  edge  of  the  fill  else- 
where protected  by  a  line  of  coralline  rocks.  At  the  high  tide 
line,  under  the  rocks,  drift  materials,  and  around  the  roots  of 
the  grasses  along  this  margin,  there  is  a  very  definite  zonation 
of  certain  species.  On  this  particular  shore,  the  zonations  of 
habitat  are  very  narrow,  and  the  species  overlap  in  their  occur- 
rence somewhat,  but  still  there  is  a  rather  definite  picture  of  the 


April,   1958  nautilus  121 

zonation,  if  careful  attention  is  paid  to  look  for  it.  Detracia 
bullaoides  (Montagu) ,  Melampus  coffeus,  M.  bidentatus,  and 
Pira  monile  (Bruguiere)  are  all  to  be  found  under  these  rocks, 
with  the  Detracia  furthest  away  from  the  water.  The  Pira  monile 
are  closest  to  the  water  line  in  this  habitat. 

One  low  spot  on  this  northern  shore  of  Plantation  Key  ap- 
parently represents  a  trace  of  the  former  typical  mangrove 
swamp  conditions.  Here  were  found  4  Detracia  bullaoides  of 
large  size;  1  specimen  of  D.  clarki;  10  Melampus  coffeus;  28 
M.  bidentatus  [of  the  small  dwarf  form  erroneously  figured  by 
Binney,  Dall,  and  others  as  Detracia  floridana  (Pfeiffer)  for 
many  years];  and  1  empty  shell  of  Pseudocyrena  maritima 
(Orbigny)  .  A  couple  of  shells  of  Cerithidea  scalariformis  (Say) 
were  drifted  on  this  north  shore,  but  they  were  not  living  in 
this  particular  area. 

The  truncatellas  are  exceedingly  abundant  here.  All  three 
Florida  species  are  living  on  this  shore,  in  slightly  different 
habitat  zones.  Closest  to  the  water,  where  they  are  probably  im- 
mersed at  every  normal  high  tide,  Truncatella  scalaris  clathrus 
Lowe  is  common  on  the  sand  under  the  rocks.  A  little  further, 
that  is  just  a  few  inches  up  the  shore,  T.  caribaeensis  Reeve  and 
T.  pulchella  Pfeiffer  appear.  The  caribaeensis  are  less  common, 
and  burrow  more  deeply  in  the  sand  under  logs  or  stones,  when 
they  are  inactive  in  the  daytime,  than  do  pulchella.  The  T. 
pulchella  population  also  extends  further  landward  into  a 
higher  and  drier  habitat.  T.  pulchella  lives  here  by  the  myriads. 
The  maximum  concentration  of  individuals  of  T.  pulcliella 
Pfeiffer  in  this  place  was  estimated  to  exceed  1,000  to  the 
square   foot. 

On  the  under  side  of  these  rocks  just  a  little  below  the  normal 
high  tide  line,  there  are  tiny  ellobiids  to  be  found.  Sitting  or 
lying  in  the  sun  is  pleasant,  but  searching  every  rock,  and  pick- 
ing off  the  tiny  snails  with  spring-steel  forceps  requires  a  sharp 
eye  and  a  patient,  steady  hand.  Pedipes  ovalis  C.  B.  Adams 
(252  specimens) ,  P.  mirabilis  (Miihlfeld)  (2  specimens) ,  and 
Laemodonta  cubensis  (Pfeiffer)  (2  immature  specimens)  were 
taken  here  in  a  couple  of  hours,  along  with  a  few  young  mussels 
of  the  genera  Crenella  and  Brachidontes,  which  were  attached 
to  the  under  surface  of  these  rocks  by  their  byssal  threads. 


122  NAUTILUS  Vol.   71     (4) 

A  little  to  the  east  along  this  north  shore,  a  small  colony  of 
Siphonaria  alternata  (Say)  was  discovered  in  the  splash  zone 
(intertidal)  near  the  high  tide  line  on  eroding  limestone  rock 
ot  the  natural  shoreline.  Although  it  was  a  simple  matter  to 
collect  100  small  specimens  with  the  point  of  a  knife  blade, 
this  colony  was  apparently  restricted  to  about  twenty  feet  of 
shore  line. 

The  other  Florida  species  Siphonaria  (Patellopsis)  pectinata 
(Linne)  was  found  in  great  abundance  on  the  creosoted  wooden 
jetties  along  the  Golden  Beach  (188th  Street  of  Miami  Beach). 
A  number  were  brought  home  alive,  in  spite  of  undergoing 
some  rough  treatment  over  a  period  of  about  seven  days.  The 
night  after  they  were  placed  in  a  salt-water  aquarium  main- 
tained by  friends,  Mr.  and  Mrs.  William  Foster  of  Falls  Church, 
Virginia,  they  laid  gelatinous  egg  strings,  crowded  with  hun- 
dreds of  tiny  eggs,  on  the  glass  and  on  other  shells.  Subsequent 
check  of  these  tg'g  masses,  and  recovery  of  the  (dead)  empty  larval 
shells  later,  proves  that  this  species  has  a  pelagic  larval  stage  in 
its  life  history,  as  Thorson  (Danish  Sci.  Investigations  in  Iran, 
part  II,  pp.  225-227:  1940)  has  reported  for  the  species  Siplio- 
narin  sipho  Sowerby,  from  the  Persian  Gulf.  The  larval  shells 
of  pectinata  resemble  figure  30  F  on  p.  224  of  Thorson's  paper. 
Does  Siphonaria  alternata  (Say)  have  a  pelagic  stage,  or  does 
the  young  individual  crawl  out  of  the  tg'g  mass,  as  Thorson 
(loc.  cit.,  pp.  227-229)  has  reported  for  S.  kurracheensis  Reeve? 
Otherwise,  why  are  the  colonies  of  alternata  apparently  so 
localized  or  restricted?  In  ecology,  the  two  Florida  species  of 
Siphonaria  exactly  parallel  the  two  species  studied  by  Thorson 
in  the  Persian  Gulf.  S.  alternata  is  found  in  the  splash  zone 
near  high  tide  line,  and  normally  remains  out  of  water  for 
hours  at  every  tide  interval.  In  direct  contrast,  the  Siphonaria 
pectinata  live  closer  to  low  water  mark,  always  wet  in  their 
natural  surroundings,  and  lay  numerous  eggs  in  soft,  gelatinous 
strings.  Their  larvae  pass  through  a  pelagic  stage  after  hatching. 

The  south  or  oceanic  shore  of  Plantation  Key  was  visited 
once.  This  slow  shore  had  apparently  been  partly  cleared  at  one 
time  by  burning  off  the  mangroves  or  other  trees.  Only  a  few 
Tectarius  muricatus  (Linn^)  and  Littorina  angulifera  (Lamarck) 
were  to  be  found  here  on  the  stumps  drifted  up  on  the  beach. 


April,  1958  nautilus  123 

Nearby,  on  and  under  boards,  and  a  low  shrubby  plant  mat, 
Melampus  were  abundant  on  the  lowest,  most  swampy  part  of 
this  shore  line.  Melampus  coffeus  (18)  and  M.  bidentatus  (156) 
were  here  in  about  a  1  to  8.6  ratio.  Both  these  species  were 
extremely  active,  about  5:00  p.m.  just  at  dusk,  after  a  rain,  as 
the  tide  was  coming  in.  Empty  shells  of  Ellobium  pellucens 
(Menke)  were  seen  in  the  drift,  but  no  living  ones  were  dis- 
covered before  darkness  and  the  mosquitoes  necessitated  a 
retreat    from    this    south    shore. 

Stops  were  made  at  several  places  on  the  way  back  to  Wash- 
ington, to  look  for  Melampus  and  Detracia.  The  edge  of  the 
(J.  S.  No.  1  highway  embankment  along  a  tributary  of  the 
Halifax  River,  2  miles  south  of  Allandale,  Volusia  County, 
Florida,  yielded  a  few  Melampus  coffeus  and  M.  bidentatus. 
Nearby,  under  oyster  shells,  etc.,  on  a  fill,  at  the  extreme  high 
tide  level  in  this  estuary,  Truncatella  pulchella  Pfeiffer  was 
found  in  moderate  abundance.  How  much  further  north  along 
the  east  coast  of  Florida,  does  M.  coffeus  live?  A  look  at  the 
map  indicates  that  it  probably  should  be  living  naturally  at 
least  as  far  as  the  north  end  of  the  Halifax  River  estuary 
system,  that  is  about  15  miles  north  of  the  city  of  Daytona 
Beach.  It  is  interesting  to  note  that  this  Volusia  County  record 
on  the  east  coast  is  just  about  five  miles  south  of  the  latitude 
of  the  northernmost  record  of  M.  coffeus  known  to  me  from  the 
west  coast  of  Florida.  That  is,  Hemphill's  record  from  the 
Cedar  Keys. 

To  the  northward,  at  inlets  along  the  road  on  St.  Simon's 
Island,  Georgia;  and  south  of  Murrell's  Inlet,  South  Carolina; 
and  south  of  Myrtle  Beach,  South  Carolina,  along  route  No. 
17,  the  facies  or  aspect  of  the  population  of  Melampus  biden- 
tatus Say  is  changed.  The  M.  bidentatus  in  these  marshes  north 
of  Florida  appear  more  uniform;  the  shells  of  any  one  popula- 
tion seem  much  less  variable  both  in  size  and  color,  than  is 
the  case  in  the  populations  seen  from  the  Florida  Keys.  In  this 
group,  as  in  some  others  known,  there  possibly  are  more  gen- 
erations of  Melampus  per  calendar  year  unit  in  the  subtropical 
climate  of  Florida  in  which  M.  cogens  lives,  than  there  are  to 
the  northward  in  Chesapeake  Bay,  for  example.  With  the  same 
rate   of  variation   per  generation,   we   might   thus   explain   the 


124  NAUTILUS  Vol.   71     (4) 

much  greater  observed  variation  of  shells  to  be  found  in  the 
southern  Florida  populations.  This  change  in  the  populations  of 
M.  hidentatus  seems  to  coincide  with  the  geographic  zone  in 
which  M.  cofjeus  drops  out  of  the  picture,  and  the  common 
Chesapeake  Bay  littorinid  Melaraphe  irrorata  (Say)  shows  up 
in  the  marshes  alongside  hidentatus. 

It  will  be  interesting  for  collections  to  be  made  to  determine 
whether  Melampus  cogens  is  ecologically  restricted  to  the  range 
of  the  white  mangrove,  Rhizophora  mangle,  which  is  known 
from  Brevard  County,  southward,  or  to  the  range  of  the  black 
mangrove,  Avicennia  nitida,  which  is  known  from  St.  Johns 
and  Levy  counties,  southward;  as  well  as  spots  in  Mississippi 
and  Texas. 

At  present  writing,  no  specimens  of  Melampus  coffeus  are 
known  to  me  from  the  United  States  shores  of  the  Gulf  of 
Mexico,  westward  of  the  Cedar  Keys,  Florida.  All  such  records 
in  the  literature  that  I  have  been  able  to  trace,  particularly 
those  from  Texas,  refer  to  M.  hidentatus  which  has  been  mis- 
identified. 

The  distinction  of  Melampus  coffeus  from  M.  hidentatus  and 
from  Pira  monile  is  easily  made,  because  the  sculpture  of  the 
shell  above  the  shoulder  of  the  body-whorl  is  different  in  each 
case.  M.  hidentatus  possesses  spiral  incised  lines  on  this  part 
of  the  shell  (if  not  all  the  way  up  and  down  the  body-whorl) . 

M.  coffeus  has  no  such  spiral  incised  lines  on  the  spire  or 
the  upper  part  of  the  body-whorl.  Pira  monile,  on  the  other 
hand,  shows  a  single  spiral  row  of  epidermal  setae,  or  pit-scars 
after  loss  of  the  setae,  in  the  middle  of  each  whorl  on  the  spire. 


ADDITIONS  TO  TEXAS  MARINE  MOLLUSCA 

By   DONALD   R.   MOORE 
Gulf  Coast  Research  Laboratory,  Ocean  Springs,   Mississippi 

The  marine  mollusks  of  Texas  probably  have  been  studied 
less  than  those  of  almost  any  other  coastal  region  of  the  United 
States.  The  opaque  waters,  the  repetitious  stretches  of  sandy 
beach  and  the  dearth  of  pretty  collector's  items  probably  have 
had  much  to  do  with  this  lack  of  interest.  However,  some  450 
species  have  been  listed  by  various  authors  up  to  the  present 


April,  1958  nautilus  125 

time.  In  1952,  a  resume  of  all  marine  species  reported  from 
Texas  waters  was  published  by  T.  E.  Pulley.  This  paper  is  of 
great  value  because  it  brings  all  records  together  in  a  systematic 
list,  and  is  a  great  time  saver  for  any  worker  on  Texas  mollusks. 

The  species  have  notes  on  their  occurrence  from  Pulley's  own 
observations,  or  else  prior  authorities  are  listed.  Pulley  also 
corrected  a  number  of  errors  of  previous  workers. 

While  at  the  Institute  of  Marine  Science  at  Port  Aransas, 
Texas,  I  collected  and  observed  mollusks  in  the  vicinity  of  the 
station.  Unusually  clear  water  in  the  summer  of  1955  gave  me 
a  chance  to  dive  around  the  jetties  and  to  observe  the  living 
animals.  Some  of  these  species  were  not  listed  by  Pulley,  and 
little  information  was  available  on  others. 

All  the  species  discussed  in  this  paper  were  collected  in  the 
vicinity  of  Port  Aransas.  Most  were  collected  by  myself,  but  a 
few  were  collected  by  other  workers  at  the  Institute  of  Marine 
Science.  This  marine  station  is  located  on  the  southern  shore  of 
Aransas  Pass,  a  jettied  inlet  between  the  Gulf  of  Mexico  and 
Aransas  Bay.  The  pass  is  an  important  ship  channel,  and  is 
maintained  at  a  depth  of  over  30  feet.  Near  the  Institute,  the 
bottom  slopes  down  to  a  depth  of  about  twenty  feet  within  ap- 
proximately 150  feet  from  the  jetty.  The  bottom  consists  of 
sand,  and,  where  the  engineers  had  dumped  them,  piles  of  lime- 
stone rocks.  One  such  pile,  just  east  of  the  laboratory  dock, 
proved  to  be  a  prolific  collecting  ground. 

Most  of  these  rocks  had  many  small  holes  over  the  surface, 
and  in  each  could  be  seen  a  velvet  brown  siphon.  Small  rocks 
taken  ashore  and  cracked  open  were  found  to  be  riddled  with  a 
rock  boring  bivalve,  Lithophaga  hisulcata  (Orbigny).  Pulley 
found  this  species  in  oyster  shells  in  Aransas  Bay  where  they 
must  have  been  very  small  and  few  in  number.  In  the  rocks 
at  Aransas  Pass,  however,  they  were  quite  large  and  extremely 
numerous.  Many  specimens  were  close  to  40  mm.  in  length, 
and  the  largest  measured  42  mm.  Their  burrows,  60  to  70  mm. 
deep,  were  considerably  larger  in  diameter  deep  within  the 
rock  than  at  the  surface.  As  a  result,  an  apparently  solid  rock 
when  dropped  on  the  concrete  jetty  cap  would  easily  shatter. 
Probably  underwater  limestone  structures  would  not  last  long 
in   these   waters.

Members  of  the  family  Arcidae  are  usually  rendered  incon- 
spicuous by  dull  colors  and  a  rough  epidermis.  The  three  species 
found  in  Aransas  Pass  were  no  exception  to  this  rule.  The  larg- 
est and  most  common  was  Area  iimbonata  Lamarck.  Pulley  states 
that  fresh  dead  valves  of  this  species  have  been  found  in  this 
locality,  but  as  far  as  I  know,  no  one  has  reported  living  speci- 
mens from  inshore  waters  before.  Barbatia  domingensis  (La- 
marck) ,  cited  as  Area  retieulata  Gmelin,  was  reported  by  Pulley 
from  the  coral  banks  50  to  100  miles  offshore.  This  species  is 
smaller  than  A.  umbonata,  and  was  much  less  common.  Living 
specimens  were  found  in  the  same  general  area  as  the  preceding 
species.  A  single  live  specimen  of  Barbatia  eandida  (Helbling) 
made  a  new  record  for  the  Texas  coast.  All  these  species  are 
attached  to  rocks  by  a  byssus. 

Two  species  of  Chamidae  were  found  living  cemented  to 
rocks.  Only  one  Pseudoehama  radians  (Lamarck)  was  collected, 
but  it  was  a  large,  fully  adult  specimen  indicating  favorable 
conditions  for  a  considerable  length  of  time.  The  other  species, 
Chama  eongregata  Conrad,  was  found  to  be  more  numerous, 
but  still  rare.  Neither  genus  has  been  reported  from  Texas 
before. 

A  more  common  bivalve  was  Isogonum  alata  (Gmelin). 
Rather  small  live  specimens  were  collected  from  rocks  along 
the  edge  of  the  jetty. 

Among  the  gastropods,  Cantharus  tinetus  (Conrad)  was  to  be 
found  everywhere,  living  on  rocks  and  pilings.  This  species  was 
reported  by  Whitten  et  al  in  1950.  Before  that,  Dall  and  Strecker 
had  both  listed  it  as  occurring  in  Texas.  However,  Pulley  said 
it  does  not  live  in  Texas. 

A  live  specimen  of  Dnipa  didyina  Schwengel  was  something 
of  a  surprise.  This  species  was  described  in  1943  from  the  east 
coast  of  Florida,  and  this  is  the  first  record  from  the  Texas  coast. 

Another  uncommon  species  was  Monilispira  leueoeyma  (Dall). 
One  dead  and  two  live  specimens  were  collected  from  the  rock 
pile  just  east  of  the  laboratory  dock. 

Faseiolaria  distans  Lamarck  has  been  reported  by  Pulley  as 
living  offshore  in  15  to  30  fathoms.  During  the  month  of  July, 
1955,  this  species  was  fairly  common.  Most  specimens  were  found 
under  rocks,  but  one  was  found  crawling.  A  larger  species  of 


April,   1958  nautilus  127 

the  same  genus,  Fasciolaria  (Pleuroploca)  gigantea  Kiener,  was 
not  as  common.  However,  I  found  four  live  specimens  one  day. 
They  were  not  very  large,  200  mm.  to  250  mm.,  and  were  prob- 
ably immature.  Eggcases  of  this  species  commonly  wash  up  on 
the  beach  at  Mustang  Island  during  the  summer  months. 

The  sand  bottom  along  the  jetties  was  also  examined.  A  small 
venerid  clam,  Chione  grus  (Holmes),  was  taken  alive.  This 
species  was  reported  by  Ladd,  1951,  but  not  by  Pulley.  A  live 
Mangelia  cerina  (Kurtz  and  Stimpson)  was  also  found.  Ceri- 
thiiim  floridanum  Morch  and  Nassarius  ambiguiis  (Pultney) 
were  represented  by  worn,  dead  specimens.  Perhaps  these  last 
two  species  were  weathered  out  of  Pleistocene  deposits. 

The  presence  of  an  oceanic  pelagic  pteropod  in  the  Pass  was 
discovered  in  an  odd  way.  The  slender  glasslike  shells  of  Creseis 
acicula  Rang  pierced  my  hand  in  numerous  places  while  I  was 
changing  strainers  on  the  underwater  intake  pipe  below  the 
laboratory  dock.  These  animals  had  been  drawn  into  the 
strainer,  and  had  been  caught  with  the  sharp  pointed  apical 
end  protruding.  The  weather  for  some  time  preceding  had  been 
calm,  the  water  clear,  and  Gulf  water  quite  probably  had  moved 
in  almost  to  the  beach.  However,  the  pteropod  invasion  must 
have  been  of  short  duration,  for  ideal  conditions  do  not  last 
long  on  the  Texas  coast. 

Among  beach  drift  specimens  collected  by  C.  E.  Dawson  and 
Henry  Hildebrand,  several  were  of  more  than  ordinary  interest. 
Epitonium  novangliae  (Couthouy)  is  reported  from  Texas  by 
Clench  and  Turner  in  Johnsonia,  1952,  but  it  is  not  on  Pulley's 
list.   Several  specimens  were   found. 

A  gastropod,  Odostomia  seminuda  (C.  B.  Adams),  was  the 
smallest  specimen  identified  from  beach  drift.  Odostomia  en- 
gonia  Bush  was  scarcely  larger.  This  last  species  has  not  been 
reported  from  the  Gulf  before. 

Several  small  bivalves  were  found  imbedded  in  the  tunic  of  a 
tunicate  washed  up  on  the  beach  by  March  winds.  All  specimens 
were  of  Modiolaria  lateralis  (Say),  a  moUusk  often  found  asso- 
ciated with  tunicates.  Very  small  specimens  were  found,  a  few 
days  later,  attached  to  blocks  of  tar  which  had  washed  ashore. 
This  species  has  not  been  reported  from  Texas  before. 

It  is  impossible  to  say  when  the  rock  living  species  came  into 


128  NAUTILUS  Vol.   71     (4) 

the  Pass,  or  where  they  came  from.  They  probably  lacked  a 
proper  substratum  before  the  Pass  was  jettied.  Those  species 
with  planktonic  larvae  probably  moved  in  shortly  after  a  hard 
substrate  was  provided.  Species  hatching  out  as  bottom  crawlers, 
such  as  Cantharus  tinctus,  would  have  to  immigrate  by  mechani- 
cal means  (on  ship  bottoms,  etc.),  and  would  take  longer  to 
settle.  Whitten,  in  1947,  found  only  one  specimen  of  C.  tinctus; 
I  found  this  species  to  be  quite  common  in  1955.  Although  our 
collecting  methods  were  admittedly  different,  this  species  pos- 
sibly had  just  begun  to  establish  itself,  and  was  quite  rare  when 
Whitten   made   his   survey. 

Most  specimens  mentioned  above  are  in  the  collection  of  the 
Gulf  Coast  Research  Laboratory.

STUDIES  ON  MOLLUSK  POPULATIONS:  Illa^ 

By  R.  STOHLER 
Department  of  Zoology,  University  of  California,  Berkeley 

Dall  (1871,  p.  130)  described  a  variety  of  Chlorostoma  brun- 
neum  (Philippi)  and  gave  it  the  name  fliictuatum.  The  whorls 
of  this  new  variety  were  said  to  be  "marked  with  oblique, 
prominent,  rounded,  short  riblets."  No  type  was  designated 
nor    was    a    type    locality    mentioned. 

Almost  50  years  later,  Dall  (1919)  described  a  new  variety  of 
Ch.  hrunneum,  but  named  it  fluctuosum.  Monterey,  California, 
is  given  as  the  type  locality  and  the  type  lot  is  U.  S.  National 
Museum  Cat.  No.  60055.  The  sculpture  is  described  as  "well- 
marked  obliquely  protractive  ribs  to  the  number  of  18  or  20 
on  the  last  whorl,  reaching  from  the  suture  nearly  to  the  periph- 
ery." Dall  further  states  that  the  variety  is  less  elevated  than 
the  typical  specimens  and  that  the  suture  is  more  depressed. 
Neither  of  the   two  descriptions  is  accompanied  by   figures. 

The  variant  of  the  common  brown  turban  shell  of  the  Pacific 
coast  may  be  found,  in  varying  proportions,  in  almost  any 
population  of  this  species.  Several  careful  collections  were  made 
by  this  writer  in  different  California  localities  by  picking  up 
every  snail  that,  through  foam-sprayed  bifocal  glasses,  appeared 
to  be  a  Tegula  hrunnea;  shells  inhabited  by  hermit  crabs  were, 
however,  immediately  discarded.  In  each  case,  before  leaving  the 
collecting  area,  each  animal  was  carefully  examined  and  an 
accurate  count  was  made;  the  typical  specimens  were  returned 
to  tide  pools  and  all  individuals  showing  the  variation  to  any 
extent,   were  retained  and  later  preserved. 

In  the  accompanying  table  are  given  the  numbers  and  per- 
centages thus  found.  The  percentages  are  calculated  to  indicate

The  two  last  localities  deserve,  perhaps,  special  attention: 
the  populations  collected  are  nearly  identical  in  size  but  the 
number  of  the  variants  reach  here  the  extremes  of  the  entire 
series;  yet  the  two  localities  are  only  a  few  miles  apart  and  the 
general  features  of  the  environment  are,  as  far  as  is  apparent, 
identical,  which  seems  to  rule  out  ecological  factors. 

Another  point,  which  cannot  be  shown  in  any  table,  needs 
special  mention,  namely  the  fact  that  in  any  group  of  the  vari- 
ant (such  as  that  obtained  at  Salt  Point  or  Point  Soberanes,  but 
particularly  the  larger  group  from  Pigeon  Point)  there  is  to  be 
observed  almost  every  possible  intermediate  form  between  the 
typical  smooth  brunnea  and  the  extreme  variant  form.  This 
alone  would  suffice,  as  pointed  out  in  an  earlier  paper  of  this 
series  (Stohler,  1950) ,  to  relegate  the  variety  fiuctuosa  (Dall) 
to  the  synonymy  of  Tegula   brunnea    (Philippi) . 

However,  if  specimens  exhibiting  the  sculpture  described  by 
Dall  are  compared  with  typical  specimens  of  Tegula  aureo- 
tincta  (Forbes)  a  striking  similarity  between  the  two  becomes 
apparent  (cf.  figs.  1  and  2) .  This  similarity  has  convinced  the 
writer  that  we  are  dealing  with  a  case  of  parallel  evolution. 
Presumably,  closely  related  species  have  a  great  number  of  genes 
in  common,  whatever  the  concept  of  the  gene  may  be;  in  fact, 
it  might  be  stated  that  the  more  closely  related  two  species  are, 
the  greater  number  of  like  genes  they  possess.  In  parallel  evo- 
lution, corresponding  genes  in  different  species  undergo  similar 
mutation  trends  and  the  consequent  end  results  would  be  that 
the  species  are  more  similar  to  each  other  than  before. 

In  the  genus  Tegula,  several  series  of  shell  characters  may  be 
regarded  as  the  expression  of  such  parallel  evolutionary  trends; 
among  them  might  be  considered  the  presence — or  absence, 
whichever  did  not  occur  first — of  an  open  umbilicus,  and,  of 
course,  the  sculpture  of  the  shell.  In   T.  aureotincta  the  char-

acter,  described  by  Dall  as  a  variety  in  T.  hrunnea,  is  typical  for 
the  species.  In  T.  brunnea,  on  the  other  hand,  it  seems  to  be  a 
mutation  that  may  or  may  not  eventually  replace  the  smooth 
shell  form;  in  other  California  species,  as  far  as  is  known  at 
present,  this  character  is  extremely  rare  or  lacking  entirely. 

The  idea  that  the  "fluctuosa"  character  is  what  may  be  called 
a  parallel-evolutionary  trait  receives  support  from  the  fact  that 
at  the  time  the  group  at  Salt  Point  was  collected,  there  were 
picked  up  actually  a  total  of  81  "T.  brunnea"  animals;  but  dur- 
ing examination  at  the  shore,  as  described  above,  there  were 
found  among  these  two  T.  pulligo  (Martyn)  one  of  which  also 
exhibits  the  same  "fiuctuosa"  character    (see  fig.   3). 

It  is  considered  that  the  phenomenon  of  parallel  evolution, 
as  discussed  here,  adds  to  the  validity  of  placing  the  "varietal"

MARINE  SHELLS  OF  ILLINOIS  INDIAN  SITES 

By  PAUL  W.  PARMALEE 

Sixteen  years  have  elapsed  since  a  summary  of  marine  shells 
found  in  Indian  sites  in  Illinois  has  been  presented  (Baker, 
1941).  During  these  intervening  years,  archaeologists  have  un- 
covered additional  quantities  of  shells  which  have  not  only 
added  to  the  list  of  species  identified  but  also  to  the  knowledge 
of  the  different  Indian  cultures  and  the  importance  that  mol- 
lusks  played  in  their  daily  lives.  Probably  Dr.  Frank  C.  Baker, 
former   Director,    Museum    of    Natural    History,    University    of 


132  NAUTILUS  Vol.   71     (4) 

Illinois,  Urbana,  did  more  in  the  manner  of  identifying  speci- 
mens, interpreting  data  and  stimulating  interest  in  this  aspect 
of  conchology   than   any   other   individual   in   Illinois. 

All  Indian  sites  in  Illinois  are,  or  were  located  along  some 
body  of  water  and,  as  evidenced  by  the  quantities  of  fresh- 
water mussel  remains  found  in  midden  deposits  and  village 
refuse  heaps,  these  mollusks  provided  an  abundant  source  of 
food  that  was  normally  available,  easily  obtainable  and  un- 
limited. As  an  indicator  of  agricultural  activity,  the  values  of 
some  of  the  larger  and  heavier  species  (e.g.,  blue-point,  Amblema 
peruviana;  washboard,  Megalonaias  gigantea)  were  drilled  and 
evidently  used  as  hoes,  these  often  being  encountered  in  Hope- 
well (500  B.C.-1200  A.D.)  and  Middle  Mississippi  (1200-1550 
A.D.)  village  sites.  Crushed  mussel  shell  was  used  as  temper 
material  in  making  pottery  (primarily  Middle  Mississippi  cul- 
ture), and  often  valves  were  cut  and  fashioned  into  pendants, 
spoons,  dishes  (?),  rattles  and  various  other  ornaments  and 
utensils  (Cole  and  Deuel,  1937;  Deuel,  1952,  et  al.).  Freshwater 
snails,  especially  Anculosa  sp.,  were  often  used  as  beads. 

Marine  mollusks  occasionally  are  found  in  association  with 
Archaic  sites  (8000-2000  B.C.?)  and  somewhat  more  abundantly 
in  Hopewell,  but  not  until  the  apparent  establishment  of 
efficient  trade  routes  or  collecting  parties  by  the  Middle  Missis- 
sippi culture  do  they  appear  in  any  quantity.  Apparently  the 
marine  species  were  especially  prized  by  prehistoric  groups 
occupying  the  midwest  region  and  from  these  shells  they  manu- 
factured a  variety  of  spoons,  pendants,  dippers  and  beads  of 
numerous  types.  Without  exception,  the  greatest  quantity  and 
number  of  species  found  in  any  site  in  Illinois  thus  far  have 
been  at  Cahokia,  an  extensive  Middle  Mississippi  site  in  the 
East  St.  Louis  area  (Madison  and  St.  Clair  counties)  bordering 
the  Mississippi  River. 

The  single  most  comprehensive  work  on  Cahokia  was  done 
by  Moorehead  (1929)  and  included  an  appendix  section  by 
F.  C.  Baker,  which  also  appeared  separately  (Baker,  1923). 
Numerous  illustrations  and  descriptions  of  both  freshwater 
and  marine  species  appeared  in  the  works  of  Moorehead  (1929), 
Titterington  (1938),  and  Baker  (1941).  From  September  through 
December,  1956,  Mr.  Gregory  Perino,  Thomas  Gilcrease  Foun- 


April,   1958  nautilus  133 

dation,  Tulsa,  Oklahoma,  excavated  approximately  one  acre 
of  the  Cahokia  village.  All  bone  and  shell  was  given  to  the 
author  for  identification  and  analysis;  the  quantity  and  variety 
of  species  encountered  serve  as  a  basis  for  this  report. 

Acknowledgments:  I  would  like  to  express  my  gratitude  to 
Mr.  Gregory  Perino  and  the  Thomas  Gilcrease  Foundation, 
Tulsa,  for  their  kindness  in  giving  me  the  faunal  material  from 
Cahokia  as  well  as  permission  to  use  the  data.  I  am  especially 
grateful  to  Dr.  Henry  van  der  Schalie,  Museum  of  Zoology, 
University  of  Michigan,  Ann  Arbor,  and  to  Dr.  Joseph  P.  E. 
Morrison,  Division  of  MoUusks,  U.  S.  National  Museum,  Wash- 
ington, for  their  kindness  in  identifying  certain  specimens.  Com- 
mon and  scientific  names  have  been  taken  from  "American 
Seashells"  by  R.  Tucker  Abbott. 

Rangia  cuneata    (Gray)  Common  Rangia 

Baker  (1941)  refers  to  three  valves  of  this  species  that  were 
found  in  the  James  Ramey  Mound  (Cahokia).  An  additional 
four  specimens  were  recovered  in  the  village  midden  debris  at 
Cahokia  during  the  1956  excavations  by  Mr.  Perino.  Apparently 
marine  clams  were  not  particularly  favored  judging  from  their 
scarcity  at  sites  in  comparison  with  the  quantity  of  gastropods. 

DiNocARDiuM  sp.  Cockle 

A  small  section  of  a  cockle  was  found  by  Mr.  Perino  at  Ca- 
hokia. Specific  identification  is  impossible  but  considering  thick- 
ness and  the  scalloped  margin,  it  was  a  portion  of  a  large  valve, 
quite  possibly  a  species  of  Dinocardium.  A  similar  margin  frag- 
ment was  found  by  George  and  Ethel  Schoenbeck  at  the  Steuben 
Site    (Hopewell),    Marshall   County. 

Macrocallista  nimbosa    (Solander)  Sunray  venus 

The  left  valve  of  an  adult  specimen  was  encountered  in  a 
refuse  pit  near  Cahokia  Mound  No.  34  by  Mr.  Perino.  Although 
this  species  normally  possesses  a  glossy-smooth  shell,  the  pol- 
ished appearance  of  the  shell,  faint  scratch  lines  and  apparent 
smoothing  of  the  posterior  margin  point  to  the  fact  that  it  had 
been  worked  and  possibly  used  as  a  spoon  or  other  utensil. 
None  of  the  valves  of  R.  cuneata  showed  signs  of  having  been 
worked  and  their  use  by  the  Indian  is  open  to  question. 


134  NAUTILUS  Vol.   71     (4) 

Strombus  pugilis  Linne  West  Indian  fighting  conch 

Strombus  alatus  Gmelin  Florida  fighting  conch 

A  single,  unbroken  large  specimen  and  a  fragment  of  the 
upper  whorls  of  another,  "apparently  worked  for  an  ear  or  nose 
ornament,"  were  found  in  the  James  Ramey  Mound  (Cahokia) 
and  listed  as  Strombus  pugilis  alatus  Gmelin  by  Baker  (1941). 
Six  additional  specimens,  5.  alatus,  were  found  during  the  1956 
excavations,  four  in  a  single  large  refuse  pit  that  also  con- 
tained 190  individuals  of  Busy  con  perversum.  One  still  exhib- 
ited portions  of  the  brownish  epidermis.  This  conch  is  rare  in 
Illinois  sites  and  apparently  was  little  used  for  specific  purposes, 
with  one  exception  as  noted  above. 

LiTTORiNA  IRRORATA  (Say)  Marsh  periwinkle 

There  is  one  record  of  a  single  specimen  that  was  found  in 
the  James  Ramey  Mound  at  Cahokia  (Baker,  1923).  Quite 
possibly  this  small  snail,  common  in  the  brackish  water  marshes 
of  northern  Florida,  was  accidently  (or  incidentally)  collected 
by  the  Indian  and  transported  inland.  Apparently  this  peri- 
winkle was  not  preferred,  as  was  the  case  of  Marginella  for 
beads,  since  it  is  an  abundant  and  easily  obtainable  moUusk. 

Phalium  granulatum    (Born)  Scotch  bonnet 

A  section  of  the  outer  lip  of  this  species  was  found  in  a 
refuse  pit  in  the  Cahokia  village  by  Mr.  Perino.  This  shell 
fragment  is  evidently  the  first  record  of  P.  granulatum  from 
Illinois  Indian  sites  and,  as  apparently  is  the  case  with  other 
forms  represented  by  only  one  or  a  very  few  specimens,  probably 
was  collected   incidentally   to   the  preferred  species. 

Cassis  madagascariensis  Lamark  Emperor  helmet 

As  Baker  (1929)  pointed  out,  "Two  large  and  characteristic 
species  of  Mollusca  occur  in  the  Hopewell  group  that  are  absent 
from  the  Cahokia  group,  Cassis  madagascariensis,  and  Cypraea 
exanthema.  This  may  indicate  a  different  trade  route,  perhaps 
with  different  tribes,  because  these  shells  would  appeal  to  the 
aboriginal  mind  on  account  of  their  size  and  striking  appearance 
as  well  as  attractive  colors,  .  .  ."  1  he  emperor  helmet  has  been 
recorded  (Baker,  1941)  from  Calhoun  County  (two  specimens 
in  the  Mus.  Nat.  Hist.,  Univ.  of  111.,  Urbana);  fragments  were 


April,   1958  nautilus  135 

found  in  the  Ogden  Mound  of  the  Liverpool  group  near  Lewis- 
town,  Fulton  County  and  a  single  shell  was  removed  from 
Mound  No.  1  of  the  Montezuma  Group  in  Pike  County. 

A  complete  Cassis  shell  vessel  was  found  with  a  Hopewell 
burial  near  Oakford,  Menard  County,  about  1932  by  a  local 
farmer.  Although  the  shell  was  later  sold  to  a  private  buyer,  the 
Illinois  State  Museum  first  obtained  photographs  of  the  speci- 
men. The  most  recent  record  is  that  of  a  shell  removed  from  a 
Hopewell  mound  (Bedford  Mound  No.  9)  near  Bedford,  Pike 
County,  during  the  1955  summer  excavations  by  Mr.  Perino  for 
the  Thomas  Gilcrease  Foundation. 

MuREX  POMUM  Gmelin  Apple  Murex 

Baker  (1941)  refers  to  a  specimen  which  was  found  with  a 
burial  in  a  Hopewell  mound  (Rose  Mound,  No.  13)  in  Schuyler 
County.  The  shell  was  apparently  in  poor  condition  but  a 
drilled  hole  near  the  anterior  canal  indicated  that  it  had  been 
used  as  a  pendant  or  ornament. 

Thais  haemastoma  floridana  (Conrad)  Florida  rock  shell 
A  single,  partially  broken,  large  specimen  was  recovered  dur- 
ing Mr.  Perino's  work  at  Cahokia  in  1956.  Apparently  this  com- 
mon Florida  species  had  not  been  found  previously  in  other 
mounds  or  village  sites  in  Illinois  and  of  what  use,  if  any,  it 
may  have  been  to  the  Indian  is  questionable  since  the  shell 
bore  no  signs  of  having  been  worked. 

BusYcoN  PERVERsuM  (Linnc)  Perverse  whelk 

The  perverse  whelk  is,  without  exception,  the  most  abun- 
dant large  marine  gastropod  recovered  from  Illinois  Indian 
sites  thus  far,  and  it  has  been  found  in  association  with  all  three 
major  cultural  groups  (Archaic,  Hopewell,  Middle  Mississippi). 
This  shell  evidently  was  prized  highly,  judging  by  the  quantity 
that  has  been  found  and  the  variety  of  uses  to  which  it  has  been 
put.  In  the  case  of  the  Hopewell  Indian  (Deuel,  1952;  et  al.), 
the  shell  dippers,  made  by  removing  the  central  axis  or  colum- 
ella, were  buried  in  mounds  with  the  dead.  Possibly  because 
they  were  more  difficult  to  obtain  since  there  were  fewer  or  less 
well-established  trade  routes,  the  earlier  Hopewell  prized  these 
whelks  even  more  than  the  later  Mississippi  people.  Rarely  if 


136  NAUTILUS  Vol.   71     (4) 

ever  are  complete,  or  even  fragments,  of  marine  shells  found 
in  midden  debris  and  refuse  pits  in  Hopewell  villages,  while 
remains  of  them  are  often  abundant  in  Middle  Mississippi  vil- 
lage areas    (e.g.,  Cahokia). 

No  site  in  Illinois  has  yielded  such  a  tremendous  number 
of  B.  pei'versum  as  has  Cahokia.  Although  dippers  were  made 
from  this  species  by  Middle  Mississippi  people,  they  were  prob- 
ably sought  more  for  their  use  in  the  manufacture  of  ornaments, 
beads  and  other  objects.  At  Cahokia  disk  beads,  cut  from  the 
whorls,  were  abundant  as  well  as  sections  of  the  axis  that  had 
been  drilled  lengthwise.  Complete  small  and  medium-sized 
shells  were  drilled  and  evidently  worn  as  pendants,  as  were 
numerous  pieces  that  had  been  cut  into  a  variety  of  shapes  and 
sizes.  Mr.  Perino  recovered  nearly  300  identifiable  specimens 
of  B.  perversum  during  his  1956  excavations  at  Cahokia  and  a 
large  number  of  sections  and  fragments  that  are  probably  assign- 
able to   this  species. 

BusYCON  CARICA    (Gmelin)  Knobbed  whelk 

Baker  (1941)  points  out  that  the  shell  illustrated  in  Moore- 
head  (1929),  plate  XXXI V,  fig.  2,  "appears  more  like  a  re- 
versed carica  than  a  specimen  of  perversum."  Because  of  altera- 
tion by  working  and/or  the  fragmentary  state  of  many  shells, 
it  would  be  difficult  to  distinguish  B.  carica.  A  few  specimens 
have  been  identified  from  Cahokia  (Moorehead,  1929,  plate 
XXIV,  fig.  16)  but  apparently  it  never  was  collected  in  any 
quantity. 

BusYcoN  CANALicuLATUM   (Linn^)  Channeled  whelk 

One  small  (3  inch)  shell  was  removed  from  a  refuse  pit  dur- 
ing the  excavations  at  Cahokia  in  October,  1956.  It  had  not 
been  recorded  previously  from  Indian  sites  in  the  state  and, 
again,  may  have  been  collected  incidental  to  preferred  species. 
The  absence  of  such  generally  common  species  may  be  explained 
on  the  basis  of  local  collection  points,  i.e.,  possibly  the  Indians 
located  areas  where  preferred  species  (such  as  B.  perversum) 
were  abundant  and  although  a  variety  of  other  species  occurred 
in  the  area  and  were  collected,  they  were  not  taken  in  signifi- 
cant numbers. 


April,  1958  nautilus  137 

BusYCON  spiRATUM    (Lamarck)  Pear  whelk 

Eight  adult  specimens  of  this  rather  delicate  and  thin-shelled 
whelk  were  encountered  in  the  village  midden  debris  at  Ca- 
hokia  by  Mr.  Perino.  None  of  these  shells  showed  signs  of  having 
been  worked  or  used,  although  the  single  specimen  removed 
from  the  James  Ramey  Mound  had  been  drilled  and  apparently 
used  as  a  pendant    (Baker,   1941). 

Fasciolaria  tulipa  (Linne)  True  tulip 

A  single,  somewhat  weathered  specimen  of  a  relatively  large 
individual  was  recovered  from  a  refuse  pit  by  Mr.  Perino  near 
Cahokia  Mound  No.  34.  Because  of  its  only  partially  complete 
condition  specific  determination  is  difficult,  but  the  shell  com- 
pared most  closely  with  F.  tulipa.  There  is  no  evidence  as  to 
its  use  by  the  Indian. 

Fasciolaria  hunteria  (Perry)  Banded  tulip 

Baker  (1941)  refers  to  a  single  shell  of  this  common  western 
Florida  snail  {F.  distans  Lamarck)  occurring  in  the  James 
Ramey  Mound  at  Cahokia.  Apparently  no  additional  specimens 
have  been  recovered  in  the  ensuing  years  since  1922. 

Pleuroploca  gigantea    (Kiener)  Florida  horse  conch 

A  young  specimen,  portions  of  a  moderately  sized  individual, 
a  whorl  section  from  an  adult  shell  and  a  section  of  columella 
of  an  animal  approximately  15-18  inches  in  length  were  found 
in  the  midden  deposit  at  Cahokia  by  Mr.  Perino.  A  portion  of 
the  axis  of  this  large  marine  snail  was  encountered  in  the 
James  Ramey  Mound  (Baker,  1941).  None  of  these  remains  bore 
evidence  of  having  been  utilized  as  pendants,  utensils  or 
other  artifacts. 

Prunum  apicinum   (Menke)  Common  Atlantic  marginella 

Although  Mr.  Perino  encountered  only  one  shell  of  this  species 
during  his  four  months  of  excavation,  they  have  been  found 
in  considerable  numbers  at  Cahokia  (Baker,  1941),  late  Wood- 
land sites  in  Jersey  County  (Illinois  State  Museum  collection: 
specimens  donated  by  Dr.  P.  F.  Titterington,  St.  Louis)  and 
elsewhere.  This  small  snail  was  used  primarily  for  making 
beads,  the  side  of  the  shell  being  ground  until  the  body  cavity 


138  NAUTILUS  Vol.   71     (4) 

was  exposed;  this  and  the  natural  opening  served  for  threading 
the  beads.  Several  thousand  specimens,  forming  a  large  blanket 
which  covered  a  burial,  was  found  in  Powell  Mound  No.  1 
at  Cahokia.  Beads  made  from  this  species  were  encountered 
with  burials  at  the  Dickson  Mound  Cemetery  (Middle  Missis- 
sippi), Fulton  County. 

Oliva  sayana  Ravenel  Lettered  olive 

Numerous  specimens  were  encountered  in  Powell  Mound  No. 
2  and  a  single  individual  in  the  James  Ramey  Mound  (Baker, 
1941).  The  spire  had  been  removed  from  the  Ramey  Mound 
specimen,  possibly  for  use  as  a  pendant,  but  those  from  the 
Powell  Mound  showed  no  evidence  of  having  been  utilized.  A 
single  set  of  approximately  134  "Olivella"  beads  (O.  sayana) 
were  found  with  a  burial  at  the  Dickson  Mound  Cemetery, 
Fulton  County. 

Olivella  jaspidea   (Gmelin)  Jasper  dwarf  olive 

Approximately  85  specimens  of  this  small  snail  from  south- 
eastern Florida  were  found  in  the  Morton  Mound  (F°14,  Mid- 
dle Mississippi)  in  Fulton  County  (Cole  and  Deuel,  1937). 
The  apex  had  been  perforated  and  the  shells  apparently  strung 
as  beads.  Titterington  (1935,  pi.  8,  fig.  c)  found  33  shell  beads 
with  a  burial  uncovered  in  a  western  Jersey  County  mound. 

Cancellaria  reticulata    (Linne)  Common  nutmeg 

A  central  axis  from  this  common  Florida  snail  was  found  in 
Powell  Mound  No.  2  at  Cahokia.  Baker  (1941)  states  that  "It 
was  cut  so  as  to  show  to  advantage  the  spiral  plaits  or  ridges 
on  the  columella  and  its  use  was  doubtless  as  an  ornament, 
possibly  as  a  pendant  for  a  necklace  of  Marginellas." 

Summary 

Marine  mollusks,  especially  the  gastropods,  were  highly  fav- 
ored by  the  prehistoric  Indians  of  Illinois  and  they  were  used 
in  the  manufacture  of  dippers,  spoons,  drills,  beads,  pendants 
and  other  ornaments  and  utensils.  Although  marine  shells  have 
been  encountered  in  Archaic  sites,  and  somewhat  more  com- 
monly in  the  later  Hopewell  Culture  (primarily  Busycon  per- 
versum   dippers) ,   the  greatest   number   and   variety   of  species

have  been  found  in  Middle  Mississippi  sites. 

During  the  last  four  months  of  1956,  Mr.  Gregory  Perino, 
Thomas  Gilcrease  Foundation,  Tulsa,  excavated  nearly  one  acre 
of  the  Cahokia  village  in  Madison  County,  Illinois.  From  the 
tremendous  quantity  of  bone  and  shell  removed,  approximately 
325  specimens  of  marine  mollusks  were  identified  and  6  of  the 
1 1  species  determined  from  this  sample  had  not  been  previously 
reported  from  sites  in  Illinois.  The  forms  new  to  Illinois  sites 
are:  Dinocardium  sp.,  Macrocallista  nimbosa,  Phaliiim  granu- 
latum,  Thais  haemastoma  floridana,  Busycon  canaliculatum  and 
Fasciolaria   tulipa.

REPORT  ON  CONUS  BERMUDENSIS  CLENCH 

By  T.  R.  a.  NIELSEN 

Dr.  Clench  in  Johnsonia  (Vol.  1,  No.  6,  pp.  34-35)  described 
a  new  species  of  cone  from  Bermuda,  however  I  feel  that  the 
following  report  will  add  greatly  to  the  available  information 
on  this  interesting  shell.  This  report  is  based  on  my  findings 
over  a  three  year  period  of  diving,  collecting  and  study,  during 
which  time  I  have  collected  about  three  hundred  specimens  both 
living  and  dead. 

So  far  as  is  known,  Conus  hermudensis  (pi.  11)  occurs  only  in 
Bermudan  waters  and  has  been  found  living  in  water  up  to 
thirty-five  feet  in  depth  (deeper  waters  have  not  yet  been 
explored  due  to  difficult  dredging  conditions)  and  is  to  be  found 
only  in  harbor  waters  and  not  in  the  open  sea.  The  specimens 
upon  which  this  report  is  based  were  collected  by  the  author 


140  NAUTILUS  Vol.   71     (4) 

in  the  following  areas:  Grace  Island,  Spanish  Point,  Hawkins 
Island,  north  side  of  Long  Island  and  Two  Rock  Passage. 

Conus  bermudensis  prefers  a  shell-mud  bottom  fairly  thickly 
overgrown  with  long  marine  grasses  and  is  usually  found  partly 
buried  so  that  only  part  of  the  shell  is  visible  to  the  swim- 
ming collector. 

During  the  late  summer  (Aug.)  Conus  bermudensis  is  often 
to  be  found  in  pairs  (sometimes  in  threes)  adhering  to  each 
other  which  may  indicate  that  this  is  their  breeding  season. 
Living  specimens  of  this  shell  are  fairly  easy  to  obtain  in  a 
few  small  areas,  but  perfect  specimens  (from  a  fussy  collector's 
standpoint)  are  very  rare;  usually  the  shells  are  badly  worn. 

Two  distinct  color  forms  exist;  one  is  pale  pink  with  blotches 
of  darker  pink  or  even  brick  red,  and  the  other  is  pale  orange 
with  blotches  of  darker  orange  or  even  rusty  orange.  These 
two  color  forms  never  merge  and  one  can  easily  differentiate 
between  them.  I  would  like  to  note  here  that  both  color  forms 
can  be  found  in  a  bed  of  these  shells,  indicating  perhaps  a 
sexual  difference  rather  than  a  racial  one.  The  orange  color 
form  seems  to  be  much  harder  to  obtain  than  the  pink  form.  I 
also  wish  to  note  that  on  two  occasions  I  have  taken  a  pure 
white  specimen,  but  these  were  not  albinos. 

Sculpturing  on  mature  specimens  consists  of  seven  to  ten 
incised  lines  covering  the  lower  third  of  the  shell  and  often 
very  faintly  over  the  rest  of  the  body  whorl,  however  young 
shells  often  display  heavy  grooving  over  the  entire  length  of 
the  body  whorl  and  sometimes  these  grooves  were  broken  to 
form  heavy  beading. 

The  operculum  is  very  small,  being  only  about  1/1 6th  the 
length  of  the  aperture  and  is  roughly  oval  in  shape.  It  is  very 
thin  and  light  brown  or  tan  in  color. 

The  perioscutum  is  thin  and  opaque  and  rusty  brown  in 
color,  but  is  usually  badly  worn  in  mature  specimens. 

The  radular  teeth  are  very  tiny,  each  being  about  .23  mm. 
long,  and  are  of  the  usual  barbed,  harpoon-like  kind  found  in 
most  of  the  Conidae    (Plate  12,  fig.  4,  x   300). 

Early  morning  collecting  disclosed  that  Conus  bermudensis 
feeds  on  annelid  worms,  which  the  cone  finds  just  under  the 
surface   of   the    mud-shell   sea-bed.

LAND  SNAIL  DISPERSAL 

By  H.  BURRINGTON  BAKER 

This  will  deal  largely  with  generalities.  Generalities  do  exist 
in  taxonomic  problems,  although  generalizations  or  general 
laws  usually  are  very  dangerous. 

The  first  question  to  ask  is:  What  is  a  land  snail?  The  answer 
is  that  there  is  not  any  such  thing.  In  fact,  one  might  say  that 
no  such  thing  as  a  land  animal  exists.  For  example,  you  readers, 
who  undoubtedly  consider  yourselves  land  inhabitants,  actually 
see  under  water,  hear  under  water,  breathe  under  water  and 
carry  on  all  your  life  processes  in  dilute  salt  water.  You  are 
able  to  live  on  land  only  because  you  make  tanks  of  yourselves; 
in  other  words,  you  really  are  perambulating  aquaria. 

But,  as  compared  to  you,  the  land  snails  are  very  inefficient 
and  leaky  tanks.  None  can  live  actively  except  in  the  presence 
of  water  or  in  humidity  rather  near  the  dew  point.  But  mollusks 
do  have  remarkable  powers  of  aestivation,  and,  some  land  snails 
can  exist  in  a  semidormant  state  during  dry  periods  for  at 
least  as  long  as  5  years.  They  are  able  to  do  this  because  they 
have  in  their  shells  reserve  supplies  of  CaCOg  (calcite  or  arago- 
nite)  to  which  they  can  add,  or  from  which  they  can  subtract 
relatively  large  quantities  during  their  growing  or  adult  life- 
times. In  order  to  prevent  asphyxiation  during  dry  periods, 
they  dissolve  CaCOg,  even  to  the  extent  of  making  holes  in 
their  shells,  in  order  to  buffer  the  CO2  (acid)  content  of  their 
blood.  This  is  correlated  with  the  fact  that  most  desert  snails 
are  calcophiles  (prefer  limestone).  The  reverse  of  this  is  also 
true;  snails  can  live  better  than  most  animals  where  CaCOg 
is  superabundant,  because  they  can  secrete  that  excess  of  lime 
into  their  shells. 

In  this  brief  consideration  of  land  snail  distribution,  paired 


142  NAUTILUS  Vol.   71     (4) 

extremes  will  be  discussed  under  four  headings,  as  follows: 

DISPERSAL  CHANCE  BARRIERS  EVOLUTION 

automotive      ->  large  numbers    (laws)    ->-  ecolo^ic  ->-  major    taxons 

adventitious    ->-  small   numbers    (luck)    ->-  zoogeographic    ->-  speciation 

By  automotive  dispersal,  progression  of  the  snails  by  their 
own  efforts  is  meant.  Although  the  foot  of  some  snails  has  mus- 
cular waves  of  contractions  which  help  them  to  travel,  none 
walks  like  you  do;  all  snails  actually  swim  with  the  beating  of 
microscopic  hair-like  processes,  called  cilia,  on  the  sole  of  the 
foot.  Thus  a  land  snail  really  swims  over  the  land,  along  a 
little  river  of  slime,  which  it  secretes  as  it  goes  forward,  largely 
from  a  hole  at  the  head  end  of  its  foot.  For  these  reasons,  snail 
species  are  proverbially  slow,  but,  in  the  hundreds  of  thousands 
of  years  of  their  history,  they  might  get  anywhere  in  the  world, 
if  some  barrier  did  not  stop  them. 

The  other  extreme  in  dispersal  is  adventitious  or  accidental 
carriage  by  other  means,  e.g.,  by  birds,  by  hurricanes,  etc.  Of 
course  it  also  includes  introduction  by  man,  but  this  usually 
is  called  artificial,  as  opposed  to  natural  dispersal.  Natural 
adventitious  dispersal,  of  course,  takes  place  very  rarely,  which 
means  that  small  numbers  are  involved.  In  this  connection, 
you  should  remember  that  the  land  snails  of  the  Pulmonata 
have  a  great  advantage  over  most  animals,  for  example,  over 
most  operculate  land  snails,  because  they  are  hermaphroditic, 
that  is,  each  animal  has  both  male  and  female  organs  and  can 
fertilize  its  own  eggs.  Thus,  in  such  hermaphrodites,  the  acci- 
dental transport  of  one  juvenile  individual  might  start  a  new 
colony.  On  the  other  hand,  in  order  to  establish  a  species  with 
separate  sexes,  at  least  a  young  male  and  a  female  must  be  intro- 
duced simultaneously;  in  fact,  one  can  prove  mathematically  that 
still  larger  numbers  probably  would  be  required.  To  illustrate 
this  by  a  hypothetic  case,  suppose  that  the  chances  are  a  million 
to  one  against  the  arrival  of  one  animal  by  accidental  transport 
in  a  given  time  period — say  one  year,  which  would  mean  one 
might  expect  several  during  the  last  geologic  era.  Then  the 
chances  would  be  2  billion  to  1  against  the  simultaneous  but 
independent  arrivals  of  two  animals  of  opposite  sexes — 2  mil- 
lion times  as  great,  which  would  not  allow  enough  time  since 
the  beginning  of  the  better  known  geologic  eras  in  the  Cambrian. 

This  naturally  leads  up  to  the  difference  between  large  and 


April,   1958  nautilus  143 

small  number  chance.  Of  course,  automotive  dispersal,  since  it 
takes  place  over  a  broad  front  or  periphery,  involves  large  num- 
bers, while  adventitious  transport  is  rare  and  may  be  limited  to  a 
single  individual. 

The  rather  fundamental  difference  between  large  and  small 
number  chance  may  be  exemplified  by  throws  of  a  die — one  of 
the  pair  of  cubes  used  in  "craps"  or  backgammon.  As  you  know, 
each  die  has  6  sides  with  numbers  of  spots  from  1  to  6.  If  you 
throw  a  die  many  times,  you  can  predict  with  mathematic  accu- 
racy that  1/6  of  the  throws  will  result  in  one  spots  (e.g.,  6000 
throws  means  1000  ±  31.6).  On  the  other  hand,  if  you  throw 
a  die  only  once,  no  one  can  prophesy  that  you  will  get  an  ace.  In 
fact,  mathematically  speaking,  the  same  is  true  of  4  throws,  be- 
cause 4  throws  are  not  significantly  different  from  none.  Even  9 
throws  would  only  reach  the  borderline  of  careful  mathematic 
significance.   Small  number  chance  is  luck,  pure  and  simple. 

Thus,  although  automotive  dispersal  may  be  defined  in  terms 
of  general  laws,  this  is  not  true  of  adventitious  transport.  The 
accidental  arrival  of  one  species  and  the  absence  of  another  may 
be  a  matter  of  sheer  luck.  Thus,  in  any  one  case,  even  though 
my  hypothetic  hermaphrodite  geophile  had  an  advantage  of  2 
million  to  one,  an  operculate  snail,  with  separate  sexes,  just 
might  happen  to  be  2  million  times  as  lucky,  and  be  the  one  to 
get  transported. 

In  time,  dispersal  means  that  each  species  would  occur  every- 
where unless  it  be  stopped  by  barriers,  which  also  have  two  ex- 
tremes, which  I  am  calling  ecologic  and  zoogeographic.  Since  the 
distinction  between  these  two  is  a  matter  of  semantics,  I  must 
define  my  terms.  As  used  here,  an  ecologic  barrier  is  one  that 
involves  only  one  gradient,  in  some  climatic,  physiographic  or 
biologic  factor,  or  complex  of  factors;  it  is  readily  crossed  by 
ecesis,  e.g.,  by  slight  gradual  adaptation  to  changed  conditions 
during  automotive  dispersal.  On  the  other  hand,  I  mean  by  a 
zoogeographic  barrier  one  that  involves  two  opposing  gradients, 
the  crossing  of  which  almost  always  requires  sporadic  adventi- 
tious transport.  Before  proceeding,  let  me  emphasize  that  the 
difference  between  them  is  not  a  matter  of  distance.  As  defined 
here,  either  may  include  thousands  of  miles,  or,  in  some  cases  of 
land  snails,  distances  of  much  less  than  a  mile. 


144  NAUTILUS  Vol.   71     (4) 

An  example,  of  a  large  scale  climatic  gradient  which  provides 
ecologic  barriers,  would  be  shown  by  a  map  which  is  one  of  a 
series  which  I  based  on  the  records  of  the  U.  S.  Weather  Bureau. 
So  far  as  I  am  aware,  no  similar  maps  ever  have  been  pub- 
lished. It  represents  the  distribution  in  the  U.  S.  of  one  aspect 
of  temperature:  The  length  of  the  growing  season.  Each  of 
the  13  color  zones  represents  a  difference  of  30  days, — from 
less  than  a  month  between  killing  frosts  on  the  summits  of 
the  Rockies  to  more  than  360  days  (practically  without  frost) 
in  the  Florida  keys  and  along  the  coast  near  San  Diego. 
Although  they  represent  actual  barriers  to  migration,  the  lines 
between  these  color  zones,  as  you  know,  are  arbitrary;  actually 
the  map  should  show  a  gradual  gradient  of  color  from  north  (or 
high  altitudes)  to  sea  level  in  the  south.  Also,  since  the  data 
mapped  are  means  over  many  years,  they  do  not  represent  the 
conditions  of  any  extreme  year.  This  means  any  zone  may  be 
much  farther  north  in  a  hot  year  and  more  to  the  south  in  a  cold 
one.  These  conditions  assist  ecesis,  in  adaptation  to  cooler  or 
warmer  temperatures.  Of  course,  since  the  spread  of  a  species  by 
ecesis  takes  place  over  a  broad  front  by  automotive  dispersal,  it 
involves  large  numbers  and  general  laws. 

For  examples  of  zoogeographic  barriers  on  a  large  scale,  I  have 
two  other  maps;  one  represents  mean  annual  rainfall,  and  the 
other  the  seasons  in  which  precipitation  exceeds  2  inches  a 
month.  In  each,  there  are  three  zones,  which  run  roughly  from 
north  to  south  and  at  right  angles  to  the  temperature  zones,  and 
in  which  the  precipitation  is  high  and  sufficient  throughout  the 
year.  These  zones  are  in  eastern  U.  S.,  the  Rocky  Mts.,  and  along 
the  Pacific  coast.  These  three  humid  zones  are  separated  by  two 
regions  of  lower  rainfall,  which  involve  two  opposing  gradients 
of  decrease  and  increase.  Thus  a  land  snail  of  humid  eastern 
U.  S.,  in  order  to  reach  the  Rockies,  would  have  to  adapt  itself 
down  a  gradient  of  decreasing  wetness,  and  then  reverse  ecesis 
and  climb  up  one  of  increasing  humidity.  Animals  almost  never 
cross  such  opposing  gradients  by  automotive  dispersal  and  ecesis. 
Adventitious  transport  is  the  method  necessary  and  this  involves 
small  numbers,  perhaps  only  single  individuals,  and  sheer  luck. 
For  land  snails,  the  double  gradients  into  the  prairies  and  steppes 
of  middle  U.  S.  have  formed  a  zoogeographic  barrier  which  has 


April,   1958  nautilus  145 

prevented   automotive  dispersal   more   effectually   than  has   the 
Pacific  Ocean. 

A  fourth  map  represents  an  attempt  to  combine  the  formulae 
given,  but  never  plotted,  by  C.  Hart  Merriam  (1898)  with  data 
on  seasonal  rainfall  corrected  for  temperature  in  the  north.  It 
shows  the  temperature  zones  and  also  shows  (more  accurately 
because  of  this  correction)   the  humid  and  dry  areas. 

These  dry  zones  form  the  boundaries  of  W.  G.  Binney's  (1878) 
and  Pilsbry's  (1948)  major  regions  of  North  America.  Of  course, 
such  maps  of  regions  represent  generalities  rather  than  general 
laws,  because  their  boundaries  should  not  be  lines  but  2  broad 
zones  of  opposing  gradients,  and  also  because  they  only  apply  to 
southern  snails  which  are  not  tolerant  to  cold.  Both  arid  zones 
pinch  out  north  of  the  U.  S.  and  represent  no  zoogeographic  bar- 
riers to  cold-resistant  snails.  Such  species  as  Retinella  electrina, 
R.  binneyana  and  Zonitoides  arhoreus  extend  across  the  conti- 
nent, as  do  the  genera  Vitrina,  Striatura  and  Discus.  But  a 
southern  snail,  in  order  to  get  around  at  the  north  would  need 
to  cross  double  gradients  of  temperature. 

One  is  apt  to  think  of  oceans  as  the  only  zoogeographic  barriers 
to  land  animals.  Of  course,  these  also  involve  two  opposing 
gradients:  down  from  land  to  water  and  up  from  sea  water  to 
land.  As  you  know,  3  major  groups  of  mammals,  the  seals,  sea 
cows,  and  whales,  have  slid  down  the  single  gradient  from  land 
to  ocean  and  become  adapted  in  various  degrees  to  marine  life. 
But  no  mammal  ever  has  crossed  by  automotive  dispersal  and 
ecesis;  these  marine  mammals  have  produced  no  terrestrial  de- 
rivatives. 

For  concrete  cases  of  zoogeographic  barriers,  with  the  sporadic- 
ity  and  pure  luck  of  adventitious  transport,  I  shall  cite  two  ex- 
amples. One  of  these  does  involve  2  or  3  thousand  miles  of  open 
ocean,  but  the  other  deals  with  a  distance  of  about  half  a  mile. 
Both  are  fundamentally  similar. 

The  first  case  is  that  of  5  Hawaiian  genera  of  limacoids  from 
the  Nearctic  (N.A.)  or  Holarctic:  Vitrina,  Striatura,  Retinella, 
Euconulus  and  Godwinia.  In  my  study  (1941)  of  Pacific  lima- 
coids, the  hypothesis  was  advanced  that  they  probably  were  car- 
ried by  migrating  birds.  In  any  case,  they  evidently  arrived  by 
adventitious  transport  for  2  reasons:  1)   Their  differences  in  dif- 


146  NAUTILUS  Vol.   71     (4) 

ferentiation,  that  indicate  they  arrived  at  widely  divergent  times. 
2)  The  luck  that  these  5  were  the  only  arrivals. 

In  regard  to  the  first,  these  differences  may  be  shown  as  follows: 

Vitrina.  Apparently  no  specific  differences  between  V.  tenella 
from  Hawaii  and  V.  alaskana  from  western  N.A.;  incidentally 
the  Hawaiian  name  is  prior.  Probably  Vitrina  is  the  latest  immi- 
grant. 

Striatiira.   At  least  2  endemic  Hawaiian  species. 

Retinella.  Hawaiian  species  3,  which  form  a  poorly  marked, 
typical  section  of  the  subgenus  Nesovitrea,  to  which  our  R.  elec- 
trina  belongs. 

Euconidus.  Hawaiian  species  belong  to  the  very  distinct  sub- 
genus Nesoconulus. 

Godwinia.  A  genus  limited  to  Hawaii  with  2  subgenera,  al- 
though it  is  most  closely  related  to  the  Mexican  Patulopsis  (in 
our  genus  Mesomphix) .  Possibly  Godwinia  has  been  longest  in 
Hawaii. 

To  take  up  the  second  reason:  Since  only  5  genera  arrived,  and 
perhaps  only  5  animals,  this  is  evidently  a  case  of  small  number 
chance.  As  for  the  proof,  why  did  these  5  taxons  reach  Hawaii, 
while  such  genera  of  small  snails  as  Hawaiia,  Zonitoides,  Pristi- 
loma  and  Discus  did  not?  The  first  2  certainly  can  live  in  Hawaii 
since  they  have  been  introduced  by  man.  In  this  connection, 
Vitrina  would  appear  to  be  the  luckiest  of  them  all,  since  it  can 
only  live  at  high  altitudes  in  Hawaii,  and  the  migratory  birds 
are  mainly  shore  species.  Evidently  the  arrivals  of  all  5  genera 
were  simple  luck. 

My  other  case  involves  calcophile  snails  on  limestone  and 
sandstone  around  the  Cumberland  escarpment  of  eastern  Ten- 
nessee and  northern  Alabama.  These  out-crops  are  separated 
from  each  other  by  zoogeographic  barriers,  which  exhibit  2  op- 
posing gradients:  from  limestone  to  less  calcareous  soils  in  the 
valleys  and  back  up  to  rock  on  the  next  outcrop.  The  most 
startling  example  I  have  seen  consisted  of  2  limestone  outcrops 
around  the  cave-sources  of  Battle  Creek,  near  Dove,  Tennessee. 
These  were  separated  by  only  about  half  a  mile  of  valley.  The 
more  eastern  one  was  visited  in  the  summer  of  1928  and  2  new 
species  were  described:  Paravitrea  xmriabilis  (1929)  and  Pils- 
hryna  castanea  (1931)  .  The  former  species  was  found  on  3  other 
outcrops,  mainly  of  sandstone,  but  was  absent  from  similar  inter- 
vening ones.   The  latter  was  found  at  only  one  other  place.    On 


April,   1958  nautilus  147 

return  in  the  spring  of  1929,  I  also  visited  the  western  source.  To 
my  great  surprise,  both  these  species  were  absent  from  this  nearby 
outcrop,  but  were  replaced  by  large  numbers  of  the  northern 
Paravitrea  multidentata,  which  I  had  not  seen  the  previous  sum- 
mer anywhere,  and  by  Zonitoides  lateumhilicatus,  for  which  I 
had  made  a  special  but  futile  search  and  had  collected  a  lime- 
stone outcrop  within  a  few  hundred  yards  of  the  type  and  only 
other  locality,  near  Gurley,  Alabama,  over  30  miles  away.  This 
evidently  exhibits  the  same  kind  of  sporadic  adventitious  trans- 
port, and  population  by  mere  luck  as  does  the  Hawaiian  example. 
To  use  Mayr's  misleading  term,  these  calcophile  snails  on  the 
two  outcrops  are  allopatric  in  the  same  sense  as  are  the  species  of 
Hawaii  and  North  America.  Of  course,  one  must  realize  that 
what  is  allopatric  for  calcophile  zonitids  would  be  sympatric  for 
birds  (or  even  non-calcophile  snails)  ;  a  bird  could  fly  or  even 
walk  a  half  a  mile  in  a  few  minutes.  Again,  Mayr's  terms  repre- 
sent generalities,  not  general  laws. 

For  brevity,  little  will  be  discussed  about  the  last  pair  of  my 
extremes,  under  evolution.  Speciation,  because  of  the  flow  of 
genes  throughout  any  continuous  range  of  a  species,  practically 
requires  isolation  by  zoogeographic  barriers,  and  may  involve 
luck.  This  fundamental  generality  was  pointed  out  about  a  cen- 
tury ago  by  Alfred  Russell  Wallace,  the  great  zoogeographer. 
Incidentally,  his  contemporary,  Charles  Darwin,  although  he 
called  his  classic  book,  "Origin  of  Species,"  largely  neglected  this, 
and  his  discussions  mainly  apply  to  the  evolution  of  major  taxons, 
such  as  genera,  families,  orders,  etc.  The  evolution  of  these  does 
not  require  zoogeographic  isolation,  and  may  follow  general  laws, 
because  fertile  crosses  between  major  taxons  of  higher  animals  do 
not  occur. 

In  fact,  as  best  provable  in  the  mammals,  the  only  land  animals 
with  sufficient  paleontologic  evidence,  the  evolution  of  major 
taxons,  especially  families,  orders,  and  higher  groups,  largely  has 
taken  place  on  big  continuous  land  masses,  such  as  continents. 
The  opposite  was  very  evident  in  the  limacoids  of  the  Pacific 
Islands.  Species  and  sections  were  very  numerous  because  of  the 
isolation  between  the  isles.  But,  all  except  those  derived  from 
adjacent  continents,  probably  by  adventitious  transport,  belong 
to  one  primitive  subfamily,  the  Microcystinae,  and  in  the  Philo- 


148  NAUTILUS  Vol.   71     (4) 

nesiae  even  the  4  genera  I  recognized  are  poorly  differentiated,  as 
Hugh  Watson  reasonably  objected.  In  this  connection,  one  must 
remember  that,  although  the  distances  between  the  Pacific  Islands 
are  greater  than  on  any  continent,  even  Eurasia,  their  total  land 
area  is  not  much  bigger  than  West  Virginia. 

In  conclusion,  let  me  repeat  my  introduction:  Generalities  do 
exist  in  taxonomic  problems,  but  generalizations  or  general  laws 
usually  are  very  dangerous.  In  other  words:  Don't  blindly  accept 
anyone's  hypotheses,  not  even  mine!

STATUS  OF  NEWCOMB'S  ACHATINELLID  NAMES 
By  ARTHUR  HADDLETON  CLARKE,  JR.i 

The  Wesley  Newcomb  Collection  of  mollusks  at  Cornell  Uni- 
versity contains  types  of  most  of  the  126  species  described  by  that 
author.  During  the  course  of  isolating  these  specimens  and  gath- 
ering material  for  a  biographical  resume  of  Newcomb  and  an 
annotated  list  of  his  species,  certain  facts  came  to  light  which 
bear  on  the  authorship  and  dates  of  58  specific  and  "varietal" 
names  in  the  Achatinellidae  attributed  to  Newcomb.  At  first 
inspection,  these  facts  might  be  interpreted  to  mean  that  these 
names  should  date  from  an  earlier  paper  by  L.  Pfeiffer,  but  such 
is  not  the  case.  It  is  desirable  to  clarify  this  issue  now  in  a  separ- 
ate publication  to  avoid  confusion  in  the  forthcoming  report. 

According  to  Waterhouse,  pp.   113  to   160  of  the  Proc.  Zool. 

Soc.  London,  21    (1853)    were  published  on  November  14,  1854 

(see  ibid.,  107 \   71-84,   1937)  .  This  section  contains  a  paper  by

Wesley  Newcomb  on  Achatinella.  Of  the  79  new  species  and  one 
variety  described,  21  species  had  already  been  described  by  New- 
comb  in  Ann.  N.  Y.  Lyceum  of  Nat.  His.,  6:  18-30  (May,  1853)  . 
Until  now,  all  names  proposed  in  these  publications  have  been 
accepted  as  originating  with  Newcomb  on  the  dates  here  given. 

In  June,  1854,  5  months  before  the  accepted  date  of  the  New- 
comb publication  in  the  Proceedings,  the  main  body  of  a  paper 
by  Dr.  L.  Pfeiffer  appeared  in  Malakozool.  Blaetter,  1854  (pp. 
112-145)  .  The  final  two  paragraphs  of  the  paper  (containing  no 
descriptions)  appeared  in  August,  1854.  These  dates  are  given  on 
the  signatures  which  were  apparently  issued  separately.  The 
conclusion  that  the  Pfeiffer  paper  preceded  the  Newcomb  paper 
in  the  Proceedings  is  substantiated  by  the  fact  that  Pfeiffer's 
paper  was  reviewed  in  the  September,  1854  issue  of  Zeits.  fiir  die 
gesammten  Naturw.   (p.  252) . 

In  this  paper,  Pfeiffer  (1)  described  in  his  own  words  50  spe- 
cies and  varieties  later  described  as  new  by  Newcomb  in  the  Pro- 
ceedings (loc.  cit.) ,  (2)  quoted  verbatim  Newcomb's  descriptions 
(loc.  cit.)  of  8  additional  species,  (3)  used  Newcomb's  names  for 
these  58  species  and  varieties,  and  (4)  cited  Newcomb  as  original 
author  in  each  case,  giving  page,  plate,  and  figure  references  to 
the  Newcomb  paper.  These  page  references  differ  in  all  cases 
from  the  pagination  in  the  Proceedings,  but  correspond  in  all 
cases  to  the  pagination  of  two  separate  copies  of  the  Newcomb 
paper  (not  issued  in  the  volume  of  the  Proceedings)  formerly  in 
Newcomb's  personal  library  and  now  in  the  main  library  at  Cor- 
nell University  (Catalog  numbers  9612  D53,  D54) .  There  is  no 
difference  in  plate  and  figure  numbering  between  the  Proceedings 
and  the  separate  copies  of  the  Newcomb  paper,  so  Pfeiffer's  plate 
and  figure  references  are  correct  for  both. 

In  a  footnote  on  page  115  (Malak.  Blatt.,  1) ,  Pfeiffer  states: 
"In  den  Proceedings  ist  die  Insel  immer  Mani  genannt;  nach  des 
Vf.  eigner  Handschrift  lese  ich  Maui,  .  .  ."  From  a  letter  from 
Pfeiffer  to  Cuming,  we  know  that  Pfeiffer  had  seen  Newcomb's 
manuscript  and  most  of  his  type  specimens,  but  the  above  quota- 
tion proves  that  Pfeiffer  had  also  seen  a  printed  copy  of  New- 
comb's paper.  The  agreement  of  Pfeiffer's  page  references  with 
the  pagination  of  the  separate  Newcomb  publication  indicates 
that  this  is  what  Pfeiffer  had  before  him. 


150  NAUTILUS  Vol.    71     (4) 

From  the  evidence  presented,  apparently  the  Newcomb  paper 
was  issued  separately  and  before  the  paper  by  Pfeiffer.  In  order 
to  decide  whether  the  58  names  involved  are  to  date  from  this 
paper  by  Newcomb  or  from  Pfeiffer,  it  must  be  determined 
whether  the  descriptions  by  Newcomb  should  date  from  the 
separate  issue  or  from  the  Proceedings. 

At  the  Paris  1948  meeting  of  The  International  Commission 
on  Zoological  Nomenclature  (see  Bull.  Zool.  Nomen.,  4:  167, 
f53,  May  25,  1950)  it  was  reaffirmed  that  a  recommendation 
should  be  submitted  to  the  Congress  to  include  in  the  regies 
words  to  the  effect  that  the  date  of  a  new  name  shall  not  be  the 
date  of  issue  of  preprints,  reprints,  or  separates  but  shall  carry 
the  date  of  the  volume  in  which  it  is  included.  The  words  pre- 
prints, reprints,  and  separates  may  be  interpreted  to  mean  copies 
of  a  work  which  are  printed  from  the  same  type  as  the  com- 
parable portion  of  the  volume,  i.e.,  separate  impressions  or  "all 
the  same  press-prints"  (Opinion  59) .  This  may  be  contrasted 
with  a  separate  edition,  which  is  not  merely  a  separate  impres- 
sion but  contains  definite  changes  in  type,  arrangement,  or 
orthography. 

A  comparison  of  the  two  issues  of  the  Newcomb  paper  reveals 
several  significant  differences.  The  separate  issue  contains  a  full 
title  page  with  the  date  1854.  The  Proceedings  issue  has  no 
separate  title  page  and  no  stated  publication  date.  The  text  of 
the  separate  issue  begins  at  the  top  of  page  3  and  ends  near  the 
center  of  the  lower  half  of  page  31,  occupying  parts  of  29  pages. 
The  text  of  the  Proceedings  issue  begins  near  the  bottom  of 
page  128  and  ends  near  the  center  of  the  lower  half  of  page  157, 
occupying  parts  of  30  pages.  Under  the  description  of  Achatinella 
cestus,  the  words  "A  fine  skull  .  .  ."  in  the  separate  issue  were 
replaced  with  "A  fine  shell  .  .  ."  in  the  Proceedings.  In  the  sepa- 
rate issue  the  words  tristis  (p.  8,  line  28) ,  porphyrea  (p.  8,  line 
45),  multilineata  (p.  14,  line  12)  and  irixistelina  (p.  14,  line  13) 
have  been  replaced  in  the  Proceedings  with  the  words  A.  tristis 
(p.  134,  line  21),  A.  porphyrea  (p.  134,  line  36) ,  A.  multilineata 
(p.  140,  line  12) ,  and  A.  mustelina  (p.  140,  line  13) .  The  colored 
plates  of  the  two  issues  show  constant  differences  also,  and  in 
general  the  plates  in  the  Proceedings  appear  to  be  more  carefully 
done.

Additional  differences  could  be  cited,  but  it  is  clear  from  the 
preceding  that  the  separate  issue  of  the  Newcomb  paper  quali- 
fies as  a  first  edition  and  not  as  a  preprint,  reprint,  or  separate. 
The  decision  of  the  international  commission  therefore  does  not 
apply  to  the  present  situation,  and  the  names  must  continue  to 
be  ascribed  to  Newcomb.  The  date  of  this  first  edition  cannot 
be  definitely  established,  but  it  is  before  June  1854,  and  prob- 
ably in  that  year. 

The  trivial  terms  of  "Achatinella"  thus  affected  are:  acuta, 
affinis,  albolabris,  ampla,  aplustre,  assimilis,  baldwinii,  biplicata,

NOTES  AND  NEWS 

Monterey  Mollusca,  corrections,  ii — In  our  discussion  of 
"Mollusks  and  Brachiopods  of  Monterey  Bay  and  Vicinity" 
(Proc.  Calif.  Acad.  Sci.,  4th  Ser.,  vol.  26,  no.  8,  Dec.  15,  1948), 
we  named  as  new  Turbonilla  (Bartschella)  bartschi  Smith  ^ 
Gordon  on  pages  222-3,  plate  3,  figure  13,  and  listed  it  on  page 
193.  Since  this  name  proved  to  be  preoccupied,  we  selected  a 
new  name,  T.  (Bartschella)  bartschiana  Smith  &  Gordon  (see 
Naut.,  vol.  62,  no.  3,  page  105) .  Dr.  Joshua  L.  Baily,  Jr.,  kindly 
informs  us  that  this  second  name  is  also  invalidated  by  Tur- 
bonilla (Chemnitzia)  bartschiana  Brown  Sc  Pilsbry  (Proc.  Acad. 
Nat.  Sci.  Philadelphia,  vol.  64,  Dec.  1912,  pp.  509-10,  figs.  4a-6) . 
This  being  the  situation,  we  accept  Dr.  Baily's  suggestion  and 
hereby  rename  the  species  T.  (Bartschella)  pauli,  new  name. 
It  still  is  known  only  from  the  type  specimen. 

On  page  207  of  the  same  paper  on  Monterey  mollusca,  Isch- 
nochiton  (Lepidozona)  golischi  Berry  is  listed  and  its  range 
discussed.  This  is  an  erroneous  use  of  the  name,  which  should  be 
corrected  to  /.    (L.)   gallina  Berry.  /.  golischi  is  a  species  so  far

Trip  to  south  Chile. — I  am  leaving  by  planes  for  southern 
Chile,  on  Nov.  25th,  where  I  will  collect  botanical  specimens  of 
all  classes  for  the  University  of  California  botanical  gardens  at 
Berkeley.  This  work  will  be  mostly  in  the  rain  forests  of  Ant- 
arctic beech  in  the  Cordillera  Pelada,  south  of  Temuco,  and 
across  the  Andes  in  Tucuman  province  of  Argentina.  Needless 
to  say,  I  will  not  pass  up  any  shells  or  fossils.  It  will  be  a  one 
man  expedition  and  I  expect  to  return  by  May  1st. — W.  J. 
Eyerdam. 

Meioceras  lermondi  as  food  for  Penaeus  duorarum? — Ex- 
aminations of  the  stomach  contents  of  the  brown-spotted  shrimp, 
Penaeus  duorarum  Burkenroad,  from  the  Tampa  Bay  area,  have 
shown  the  presence  of  Meioceras  lermondi  (Dall)  quite  fre- 
quently. One  stomach  contained  32  opercula,  a  mass  of  crushed 
shell  parts,  and  six  complete  specimens  of  M.  lermondi  (Dall) . 
This  suggests  that  this  tiny  mollusk  serves  as  a  source  of  food 
for  young  shrimp. — Bonnie  Eldred.  Fla.  State  Board  of  Con- 
servation Marine  Lab.,  St.  Petersburg,  Florida.

Zoogeography:  the  geographical  distribution  of  animals. 
By  Philip  J.  Darlington,  Jr..  1957.  675  +  xi  pp.,  1  pi.,  80  text-figs. 
John  Wiley  &  Sons.  $15.00 — In  the  classic  manner,  the  author  in- 
terprets "animals"  to  mean  higher  vertebrates,  and  "zoogeogra- 
phy" as  limited  to  inland  (land  and  fresh  water)  evidence. 
Keeping  these  two  limitations  in  mind,  his  readable  book  seems 
a  very  valuable  contribution,  and  emphasizes  wisely  the  need 
for  zoogeography  as  a  different  science  from  ecology.  And,  since 
the  mammals  are  the  only  land  animals  about  which  paleonto- 
logic  knowledge  even  approaches  sufficiency,  his  discussions  also 
should  be  of  great  interest  to  students  of  inland  mollusks,  espe- 
cially on  continents.  In  regard  to  islands,  which  naturally  are 
treated  more  briefly,  Darlington  accepts  the  importance  of  ad- 
ventitious   dispersal,    without   land   connections.    For   example,

the  Antilles  are  included  among  the  "fringing  archipelagos," 
with  the  statement  that  "different  kinds  of  vertebrates  are  repre- 
sented in  the  West  Indies  in  proportion  to  their  probable  powers 
of  crossing  water."  But  the  contributions  from  South  America 
are  so  important  (at  least  in  land  snails)  that  one  doubts  "if 
most  of  them  have  come  from  the  west  by  way  of  Cuba  or  (less 
often)  Jamaica."  Since  we  snail-chasers  are  also  human,  the  last 
chapter  on  man  will  interest  everybody. — H.  B.  B.
