  Arnold's 
  (1906) 
  doubt 
  concerning 
  the 
  correctness 
  of 
  the 
  original 
  label 
  of 
  "Santa 
  Barbara," 
  

   and 
  lack 
  of 
  specimens 
  in 
  later 
  collections 
  from 
  California, 
  has 
  led 
  authors 
  to 
  believe 
  that 
  this 
  

   species 
  has 
  not 
  been 
  found 
  north 
  of 
  the 
  Gulf 
  of 
  California. 
  Grant 
  and 
  Gale 
  (1931), 
  Hertlein 
  

   (1935), 
  and 
  Keen 
  (1937, 
  p. 
  19) 
  made 
  a 
  reasonable 
  inclusion 
  under 
  P. 
  tuinbecensis 
  d'Orbigny, 
  

   1846. 
  

  

  Two 
  syntypes 
  of 
  P. 
  paucicostatus 
  Carix>nter, 
  No. 
  15643b, 
  labelled 
  "Types 
  Sta. 
  Barbara 
  

   Jewett 
  Cooper 
  Catalina 
  Id.," 
  are 
  in 
  the 
  U. 
  S. 
  National 
  Museum. 
  There 
  are 
  also 
  two 
  syn- 
  

   types 
  in 
  the 
  Redpath 
  Museum, 
  No. 
  121, 
  labelled 
  by 
  Carpenter 
  "Type" 
  Sta. 
  Barbara 
  "Jewett 
  

   (? 
  Nicaragua)." 
  Thus 
  Carpenter 
  had 
  doubt 
  about 
  the 
  shells 
  coming 
  from 
  Santa 
  Barbara. 
  

  

  Arnold 
  figured 
  the 
  U. 
  S. 
  National 
  Museum 
  types, 
  and 
  writer 
  has 
  photographs 
  of 
  those 
  

   which 
  are 
  at 
  McGill 
  University. 
  The 
  illustrations 
  and 
  further 
  discussion 
  are 
  reserved 
  for 
  that 
  

   of 
  the 
  Carpenter 
  types 
  from 
  the 
  fauna 
  south 
  of 
  California.

  This 
  species 
  apparently 
  does 
  not 
  belong 
  in 
  the 
  West 
  Coast 
  fauna, 
  but 
  its 
  proper 
  place 
  has 
  

   not 
  been 
  established. 
  Reference 
  has 
  not 
  been 
  made 
  to 
  it 
  since 
  Carpenter 
  (1865h). 
  At 
  that 
  time 
  

   he 
  doubted 
  its 
  proper 
  locality. 
  In 
  the 
  Redpath 
  Museum 
  there 
  are 
  three 
  specimens, 
  two 
  right 
  

   and 
  one 
  left 
  valve 
  marked 
  type 
  by 
  Carpenter, 
  with 
  "Sta. 
  Barbara 
  Jewett." 
  In 
  addition 
  Car- 
  

   penter 
  labelled 
  the 
  specimen 
  "Also 
  really 
  Florida." 
  

  

  Carpenter 
  in 
  the 
  original 
  description 
  stated 
  that 
  all 
  Col. 
  Jewett's 
  specimens 
  were 
  dextral. 
  

  

  The 
  left 
  valve 
  at 
  McGill 
  would 
  then 
  be 
  eliminated 
  from 
  type 
  material. 
  Photos 
  of 
  the 
  

   McGill 
  right 
  valves 
  are 
  included 
  herein. 
  They 
  represent 
  two 
  different 
  species. 
  The 
  shell 
  of 
  

   Figures 
  2 
  and 
  3 
  of 
  Plate 
  2 
  bears 
  a 
  resemblance 
  to 
  the 
  holotype 
  of 
  P. 
  heliacus 
  Dall 
  (1925b, 
  p. 
  

   119-120) 
  as 
  figured 
  in 
  Maxwell 
  Smith 
  (1937, 
  pi. 
  9, 
  figs. 
  5a, 
  5b) 
  and 
  the 
  specimen 
  of 
  Figure 
  

   1 
  to 
  the 
  holotype 
  of 
  P. 
  acanthodes 
  Dall 
  (m 
  Smith, 
  1937, 
  pi. 
  9, 
  fig. 
  3). 
  If 
  either 
  of 
  the 
  speci- 
  

   mens 
  under 
  Carpenter's 
  name 
  proved 
  conspecific 
  with 
  one 
  of 
  Dall's, 
  Carpenter's 
  name 
  would 
  

   have 
  priority.
