  Although 
  Dall, 
  (1899), 
  gave 
  the 
  reference 
  to 
  Carpenter's 
  original 
  description, 
  he 
  omitted 
  

   it 
  in 
  his 
  1921 
  summary. 
  Oldroyd, 
  following 
  Dall, 
  did 
  not 
  give 
  the 
  reference 
  nor 
  a 
  copy 
  of 
  the 
  

   original 
  description. 
  Thus 
  the 
  impression 
  is 
  gained 
  that 
  Carpenter 
  did 
  not 
  describe 
  the 
  species 
  

   in 
  detail. 
  

  

  The 
  holotype 
  bears 
  the 
  label, 
  "Puget 
  Sound, 
  Kennerley." 
  The 
  specimen 
  is 
  of 
  both 
  valves, 
  

   but 
  the 
  hinge 
  of 
  the 
  right 
  valve 
  has 
  a 
  small 
  obstruction 
  in 
  tiie 
  umlxjnal 
  area 
  which 
  photo- 
  

   graphed 
  as 
  a 
  dark 
  patch. 
  The 
  two 
  cardinal 
  tcctli 
  in 
  the 
  left 
  valve 
  are 
  conspicuously 
  large 
  for 
  

   the 
  size 
  of 
  the 
  shell.
