  The 
  writer 
  has 
  not 
  pretended 
  herein 
  to 
  make 
  specific 
  (hscriminations 
  which 
  

   must 
  be 
  based 
  on 
  large 
  collections 
  of 
  the 
  forms 
  from 
  the 
  West 
  Coast. 
  Such 
  work 
  

   must 
  be 
  done 
  by 
  those 
  who 
  are 
  situated 
  in 
  the 
  area 
  or 
  have 
  available 
  the 
  proper 
  

   material. 
  It 
  has 
  been 
  the 
  plan 
  herein 
  to 
  make 
  available 
  to 
  those 
  distant 
  workers 
  

   the 
  facts 
  which 
  are 
  not 
  accessible 
  to 
  them. 
  

  

  PREPARATION 
  

  

  In 
  1921 
  when 
  arranging 
  collections 
  in 
  Paleontological 
  Laboratory 
  of 
  Cornell 
  

   University 
  the 
  writer 
  discovered 
  two 
  of 
  Carpenter's 
  lost 
  moUuscan 
  types 
  from 
  

   the 
  Pleistocene 
  inland 
  from 
  Santa 
  Barbara 
  (Van 
  Winkle, 
  1921, 
  p. 
  1-5, 
  PI. 
  15, 
  

   figs. 
  6-11). 
  lliese 
  were 
  in 
  the 
  scattered 
  material 
  of 
  the 
  Jewett 
  Collection 
  which 
  

   Ezra 
  Cornell 
  purchased 
  about 
  1865. 
  

  

  Twenty-three 
  years 
  later 
  93 
  Carpenter 
  "types" 
  were 
  located 
  (Palmer, 
  1945, 
  

   p. 
  97-102) 
  in 
  the 
  Peter 
  Redpath 
  Museum, 
  McCill 
  University, 
  Montreal, 
  Canada. 
  

   The 
  whereabouts 
  of 
  those 
  tyi)es 
  were 
  ])reviously 
  unknown. 
  Details 
  of 
  the 
  Car- 
  

   penter 
  shell 
  collection 
  in 
  the 
  Redpath 
  Museum 
  are 
  given 
  below 
  under 
  that 
  head- 
  

   ing. 
  Photograjjhic 
  negatives 
  were 
  made 
  of 
  the 
  specimens 
  in 
  the 
  Zoology 
  Depart- 
  

   ment 
  at 
  McCill 
  by 
  J. 
  W. 
  Pollack, 
  and 
  the 
  ])rints 
  later 
  finished 
  by 
  the 
  writer. 
  

  

  A 
  grant 
  (No. 
  788) 
  in 
  1945 
  from 
  the 
  American 
  Philosophical 
  Society 
  (Pal- 
  

   mer, 
  1946, 
  p. 
  122-133) 
  provided 
  aid 
  for 
  the 
  search 
  of 
  the 
  remainder 
  of 
  the 
  ma- 
  

   terial 
  ; 
  two 
  additional 
  trips 
  to 
  McGill 
  were 
  included, 
  and 
  more 
  types 
  were 
  found. 
  

   Before 
  1946, 
  examinations 
  also 
  had 
  been 
  made 
  in 
  the 
  Redpath 
  Museum, 
  in 
  the 
  

   Academy 
  of 
  Natural 
  Sciences 
  in 
  Philadelphia, 
  American 
  Museum

  of 
  Comparative 
  Zoology 
  at 
  Har-

  and 
  the 
  Division 
  of 
  Mollusca,

   National 
  Museum. 
  

  

  Inquiries 
  to 
  the 
  Department 
  of 
  Geology, 
  Stanford 
  University, 
  and 
  the 
  De- 
  

   partment 
  of 
  Paleontology, 
  California 
  Acadamy 
  of 
  Sciences, 
  San 
  Francisco, 
  Cali- 
  

   fornia, 
  revealed 
  that 
  no 
  Carpenter 
  types 
  existed 
  there. 
  Four 
  trips 
  were 
  made 
  to 
  

   the 
  Division 
  of 
  Mollusca, 
  United 
  States 
  National 
  Museum, 
  where 
  the 
  greatest 
  

   number 
  of 
  types 
  are 
  preserved. 
  Examination, 
  notes, 
  and 
  checking 
  were 
  accom- 
  

   plished, 
  and 
  the 
  specimens 
  were 
  photographed 
  by 
  the 
  museum's 
  photographic 
  

   staff. 
  

  

  The 
  search 
  for 
  and 
  verification 
  of 
  the 
  existence 
  of 
  types 
  in 
  the 
  Gould 
  Collec- 
  

   tion 
  at 
  the 
  New 
  York 
  State 
  Museum 
  in 
  Albany 
  was 
  facilitated 
  by 
  the 
  employ- 
  

   ment 
  of 
  the 
  author 
  as 
  temporar}- 
  ex])ert 
  in 
  /.oology 
  during 
  1945-1946. 
  This 
  al- 
  

   lowed 
  a 
  first-hand 
  examination 
  of 
  the 
  extensive 
  molluscan 
  collection 
  of 
  that 
  or- 
  

   ganization. 
  A 
  catalogue 
  of 
  the 
  first 
  duplicate 
  series 
  of 
  the 
  Reigen 
  Collection 
  of 
  

   Mazatlau 
  shells 
  was 
  iniblished 
  as 
  a 
  result 
  of 
  ])art 
  of 
  the 
  work 
  (Palmer, 
  1951). 
  

  

  At 
  the 
  request 
  of 
  Dr. 
  llarald 
  Rehder 
  a 
  paper 
  entitled 
  "Illustrations 
  of 
  Car- 
  

   penter 
  West 
  Coast 
  Molluscan 
  Types" 
  was 
  read 
  before 
  the 
  American 
  Malaco- 
  

   logical 
  Union 
  on 
  August 
  15, 
  1946. 
  

  

  A 
  visit 
  was 
  made 
  to 
  the 
  Redpath 
  Museum 
  in 
  the 
  spring 
  of 
  1949 
  for 
  the 
  ex- 
  

   amination 
  and 
  photographing 
  of 
  types 
  which 
  had 
  been 
  found 
  subsequently 
  and 
  

   to 
  check 
  queries 
  concerning 
  previous 
  notes.
