  The 
  types 
  of 
  both 
  C. 
  subdiapJiana 
  and 
  C. 
  sciiitillaefonnis 
  are 
  preserved 
  in 
  the

  The 
  holotype 
  of 
  C.

  is 
  broken. 
  It 
  is 
  labeled 
  "smashed

  There 
  are 
  many 
  fragments, 
  but 
  the 
  hinge 
  of 
  each 
  valve 
  is 
  intact, 
  

   and 
  each 
  is 
  figured 
  herein. 
  The 
  fracture 
  of 
  the 
  type 
  dates 
  to 
  Carpenter, 
  for 
  he 
  wrote 
  of 
  his 
  

   misfortune 
  in 
  regard 
  to 
  the 
  shell. 
  

  

  The 
  syntypes 
  of 
  C.

  consist 
  of 
  two 
  double 
  specimens

  a
