  There 
  is 
  in 
  the 
  Redpath 
  Museum 
  a 
  Carpenter 
  glass 
  mount 
  with 
  7 
  specimens 
  (2 
  pairs) 
  

   of 
  Semclc 
  incongrua. 
  Besides 
  the 
  specific 
  name 
  the 
  mount 
  bears 
  a 
  Carpenter 
  label 
  of 
  

   "Catalina 
  Is. 
  40-60 
  fm. 
  Cooper." 
  This 
  material 
  would 
  be 
  appropriate 
  from 
  which 
  to 
  choose 
  

   a 
  lectotype 
  for 
  the 
  species. 
  

  

  The 
  interior 
  of 
  the 
  shell 
  of 
  the 
  above 
  specimens 
  is 
  pinkish, 
  iiarticularly 
  at 
  the 
  hinge. 
  The 
  

   surface 
  of 
  the 
  shell 
  has 
  coarse 
  concentric 
  lines 
  which 
  are 
  coarser 
  on 
  the 
  right 
  valve. 
  The 
  

   concentric 
  ribs 
  are 
  wider 
  apart 
  on 
  the 
  posterior 
  end. 
  They 
  divide 
  at 
  the 
  umbonal 
  line 
  and 
  

   extend 
  as 
  two 
  ribs 
  over 
  the 
  remainder 
  of 
  the 
  surface. 
  Radiating 
  microscopic 
  lines 
  are 
  de- 
  

   veloped 
  between 
  the 
  concentric 
  ribs. 
  There 
  is 
  a 
  suggestion 
  of 
  brownish 
  or 
  i)inkish 
  rays 
  over 
  

   the 
  exterior. 
  One 
  of 
  the 
  double 
  specimens 
  (broken) 
  measures 
  17 
  mm. 
  in 
  length. 
  Another 
  

   specimen 
  measures 
  18 
  mm. 
  in 
  length 
  and 
  13 
  mm. 
  in 
  height. 
  

  

  A 
  subspecies 
  of 
  this 
  species 
  from 
  the 
  Pleistocene 
  of 
  Deadman 
  Island, 
  San 
  Pedro 
  Harlxjr, 
  

   was 
  described 
  by 
  Arnold.

  In 
  April, 
  1953, 
  William 
  K. 
  Emerson 
  of 
  the 
  Museum 
  of 
  Paleontology 
  at 
  the 
  University 
  of 
  

   California 
  sent 
  to 
  the 
  writer 
  10 
  (2 
  doubles) 
  specimens 
  (no. 
  2389) 
  of 
  S. 
  inconyrua 
  Carpenter 
  

   from 
  Santa 
  Catalina 
  Island 
  which 
  were 
  marked 
  as 
  Cooper 
  Collection. 
  There 
  are 
  no 
  other 
  

   original 
  marks 
  on 
  the 
  label 
  or 
  specimen 
  which 
  identify 
  any 
  of 
  the 
  specimens 
  as 
  type 
  or 
  

   syntypes. 
  One 
  of 
  the 
  specimens 
  is 
  not 
  Scmcle 
  but 
  a 
  Tellina. 
  The 
  remaining 
  9 
  fall 
  into 
  the 
  

   same 
  category 
  as 
  that 
  of 
  the 
  McGill 
  specimens. 
  In 
  the 
  University 
  of 
  California 
  suite 
  is 
  1 
  

   double 
  which 
  has 
  alx)ut 
  the 
  measurements 
  of 
  Carpenter's 
  original 
  dimensions, 
  0.58 
  long 
  (14.74 
  

   mm.) 
  X 
  .40 
  lat. 
  (10.16 
  mm.). 
  The 
  writer 
  includes 
  an 
  illustration 
  of 
  that 
  shell 
  (pi. 
  14, 
  figs. 
  

   7-10). 
  The 
  cardinal 
  hinge 
  area 
  and 
  interior 
  umbonal 
  region 
  are 
  rose-tinted 
  as 
  originally 
  

   described. 
  There 
  are 
  three 
  larger 
  specimens, 
  two 
  right 
  valves 
  24 
  mm. 
  and 
  23 
  mm. 
  length 
  

   each, 
  and 
  a 
  left 
  valve, 
  20 
  mm. 
  length. 
  The 
  whole 
  interior 
  of 
  the 
  largest 
  specimen 
  is 
  rosy 
  and 
  

   rosy 
  pink. 
  The 
  others 
  are 
  white 
  or 
  pinkish.
