  The 
  type 
  of 
  this 
  species 
  has 
  not 
  been 
  found. 
  The 
  collections 
  of 
  the 
  British 
  Museum 
  (Na- 
  

   tural 
  History) 
  have 
  been 
  searched, 
  as 
  well 
  as 
  those 
  in 
  likely 
  institutions 
  in 
  America. 
  

  

  Although 
  Carpenter 
  recorded 
  the 
  species 
  from 
  Monterey 
  and 
  the 
  region 
  between 
  San 
  

   Diego 
  and 
  San 
  Pedro 
  (1864b, 
  p. 
  641), 
  San 
  Diego 
  is 
  given 
  as 
  the 
  type 
  locality 
  in 
  Carpenter's 
  

   (1865g) 
  description. 
  There 
  seems 
  to 
  be 
  a 
  difference 
  of 
  opinion 
  among 
  workers 
  as 
  to 
  the 
  spe- 
  

   cific 
  rank 
  of 
  this 
  form.

  This 
  form 
  is 
  regarded 
  as 
  an 
  ecological 
  accommodation 
  to 
  the 
  animal's 
  habit 
  of 
  nestling 
  in 
  

   pholad 
  borings. 
  It 
  is 
  not 
  considered 
  a 
  species, 
  but 
  because 
  specimens 
  identified 
  by 
  Carpenter 
  

   were 
  available 
  the 
  form 
  is 
  figured 
  to 
  show 
  what 
  Carpenter 
  had 
  in 
  mind. 
  The 
  type 
  was 
  not 
  

   found. 
  The 
  specimens 
  figured 
  are 
  from 
  Neah 
  Bay, 
  collected 
  by 
  J. 
  G. 
  Swan, 
  and 
  are 
  contained 
  

   in 
  the 
  U. 
  S. 
  National 
  Museum. 
  The 
  suite 
  consists 
  of 
  four 
  double 
  valves 
  and 
  one 
  single 
  right 
  

   valve. 
  One 
  double 
  specimen 
  is 
  abnormally 
  produced 
  anteriorly 
  and 
  shortened 
  with 
  a 
  thickened 
  

   knobby 
  posterior. 
  

  

  A 
  medium 
  globose 
  specimen 
  is 
  figured.
