  The

  U. 
  S. 
  National 
  Museum 
  which 
  were 
  segregated 
  with 
  the 
  Carpenter 
  

   types 
  may 
  not 
  be 
  tbc 
  true 
  types. 
  They 
  have 
  a 
  label 
  "P.P.C." 
  "Vancouver 
  and 
  Neeab 
  Bay, 
  

   W.T.J. 
  G. 
  Swan." 
  In 
  tbc 
  case 
  of 
  Carpenter 
  authentic 
  types, 
  tbc 
  original 
  label 
  includes 
  the 
  

   word 
  "type." 
  These 
  specimens 
  (two 
  double 
  specimens 
  and 
  two 
  single 
  left 
  valves) 
  would 
  be 
  

   proper 
  specimens 
  from 
  which 
  to 
  designate 
  a 
  neotype, 
  since 
  the 
  original 
  types 
  have 
  not 
  been 
  

   found. 
  The 
  fact 
  tbat 
  the 
  specimens 
  bear 
  Carpenter's 
  initials, 
  and 
  they 
  are 
  Swan's 
  material, 
  

   would 
  identify 
  the 
  suite 
  as 
  original 
  and 
  proper 
  specimens 
  from 
  which 
  to 
  choose 
  a 
  neotype. 
  A 
  

   great 
  deal 
  of 
  Swan 
  material 
  identified 
  by 
  Carpenter 
  was 
  distributed
