  The 
  specimens 
  described 
  under 
  this 
  name 
  from 
  the 
  Cuming 
  Collection 
  and 
  Jcwctt 
  Collec- 
  

   tion 
  were 
  later 
  identified 
  by 
  Carpenter 
  (1863, 
  p. 
  31 
  ; 
  1864b, 
  p. 
  534, 
  553) 
  as 
  the 
  same 
  as 
  C. 
  bira- 
  

   diafa 
  Sowerby. 
  Carpenter 
  (1863, 
  p. 
  31) 
  corrected 
  Jewett's 
  locality 
  label 
  of 
  "Santa 
  Barbara," 
  

   and 
  suggested 
  that 
  the 
  specimens 
  probably 
  came 
  from 
  "Panama 
  or 
  Acapulco." 
  The 
  name 
  may 
  

   be 
  delected 
  from 
  the 
  list 
  of 
  specific 
  names, 
  and 
  the 
  record 
  of 
  an 
  occurrence 
  of 
  such 
  a 
  Corbula 
  

   from 
  the 
  upper 
  California 
  waters 
  may 
  be 
  eliminated.

  The

  the 
  genus 
  (Vokes, 
  1945) 
  or 
  subgenus 
  (Grant

  is 
  still 
  

   indefinite, 
  for 
  there 
  is 
  doubt 
  concerning 
  the 
  species 
  of 
  Cristofori

  Vokes

  made
