  A 
  single 
  shell 
  from 
  Port 
  Molle, 
  nearly 
  an 
  inch 
  long, 
  differs 
  from 
  

   all 
  specimens 
  of 
  this 
  species 
  which 
  I 
  have 
  examined 
  in 
  having 
  fewer 
  

   ribs, 
  separated 
  by 
  broader 
  intervening 
  sulci, 
  especially 
  down 
  the 
  

   anterior 
  side, 
  and 
  in 
  being 
  yellowish 
  with 
  less 
  and 
  paler 
  blotching 
  

   with 
  reddish 
  purple 
  except 
  within 
  the 
  valves, 
  where, 
  on 
  account 
  of 
  

   not 
  being 
  concealed 
  by 
  a 
  deposit 
  of 
  callus, 
  it 
  is 
  especially 
  vivid. 
  

   The 
  number 
  of 
  cost^e 
  in 
  this 
  specimen 
  is 
  forty, 
  and 
  in 
  typical 
  ex- 
  

   amples 
  there 
  are 
  usually 
  about 
  ten 
  more. 
  Cardium 
  modestum 
  of 
  

   Philippi 
  is 
  also 
  an 
  allied 
  species, 
  with 
  still 
  fewer 
  and 
  stouter 
  ribs, 
  

   numbering 
  altogether 
  about 
  thirty-iive 
  or 
  thirty-six. 
  C. 
  imdti- 
  

   striatum 
  was 
  originally 
  described 
  by 
  Sowerby 
  in 
  the 
  Proc. 
  Zool. 
  Soc. 
  

   without 
  a 
  locality, 
  and 
  subsequently 
  was 
  stated 
  by 
  him 
  to 
  come 
  

   from 
  St. 
  Elena, 
  West 
  Colombia 
  ; 
  but 
  this, 
  I 
  am 
  inclined 
  to 
  tliink, 
  

   requires 
  corroboration.

  The 
  number 
  of 
  ribs 
  in 
  this 
  species 
  may 
  vary 
  from 
  thirty-one 
  to
