  We 
  have 
  excluded 
  from 
  the 
  synonymy 
  tlie 
  C. 
  crihraria 
  (Buc- 
  

   cinum) 
  of 
  Lamarck 
  and 
  of 
  some 
  other 
  authors, 
  because 
  at 
  least 
  

   two 
  species 
  apjDear 
  to 
  have 
  been 
  confounded. 
  One 
  inhabits 
  the 
  

   Panama 
  zoological 
  province, 
  and 
  the 
  other, 
  the 
  Caribbean 
  seas. 
  

   The 
  Caribbean 
  type 
  is 
  that 
  which 
  generally 
  bears 
  the 
  Lamarck- 
  

   ian 
  name 
  in 
  the 
  collections 
  of 
  the 
  United 
  States. 
  In 
  Jamaica, 
  

   we 
  have 
  taken 
  several 
  varieties 
  of 
  it, 
  all 
  of 
  which 
  are 
  distin- 
  

   guishable, 
  by 
  slight 
  differences, 
  from 
  the 
  Panama 
  type. 
  Kie- 
  

   ner's 
  figures 
  (Buccinum, 
  pi. 
  16. 
  f

  resemble 
  the 
  Caribbean 
  

   rather 
  than 
  the 
  Pacific 
  type. 
  This 
  author, 
  however, 
  says 
  of 
  the 
  

   species 
  : 
  — 
  " 
  Habite 
  les 
  mers 
  des 
  Indes, 
  I'lle 
  de 
  1' 
  Ascension 
  et 
  les 
  

   cotes 
  de 
  Goree, 
  ou 
  elle 
  est 
  tr^s 
  abondante." 
  And 
  Lamarck 
  

   gives 
  as 
  the 
  habitat 
  of 
  his 
  shell, 
  " 
  les 
  mers 
  du 
  Java, 
  M, 
  Lesche- 
  

   nault." 
  The 
  Caribbean 
  shell, 
  however, 
  has 
  been 
  described 
  by 
  

   Professor 
  Bunker 
  (Zeitschr.

  Whether 
  there 
  be 
  also 
  an 
  Indian 
  species, 
  which 
  

   furnished 
  the 
  Lamarckian 
  type, 
  remains 
  to 
  be 
  ascertained.

  Most 
  of 
  our

  were 
  found 
  at

  We 
  collected 
  

   about 
  75

  is 
  figured
