  The 
  text 
  of 
  Duclos 
  (in 
  Chenu 
  111. 
  Conch.) 
  is 
  somewhat 
  

   ambiguous 
  ;

  The 
  Bay 
  of 
  Magdalena 
  is 
  much 
  farther 
  north 
  

   than 
  Costa 
  Rica, 
  on 
  the 
  outside 
  of 
  the 
  peninsula 
  of 
  California 
  

   in 
  latitude 
  24° 
  80' 
  N. 
  Probably 
  a 
  different 
  punctuation 
  

   should 
  have 
  been 
  used, 
  so 
  as 
  to 
  indicate 
  two 
  distinct 
  localities. 
  

  

  We 
  obtained 
  17 
  fine 
  large 
  specimens 
  in 
  the 
  fruit 
  shanty 
  

   before 
  mentioned. 
  They 
  were 
  said 
  to 
  have 
  been 
  taken 
  

   " 
  down 
  the 
  bay." 
  Their 
  condition, 
  and 
  the 
  other 
  shells 
  which 
  

   were 
  with 
  them, 
  fully 
  confirmed 
  the 
  statement.

  If 
  Lamarck 
  and 
  Duclos 
  have 
  sometimes 
  gone 
  into 
  the 
  one 
  

   extreme 
  of 
  excessive 
  multiplication 
  of 
  species, 
  Mr. 
  Reeve 
  has, 
  

   we 
  fear, 
  in 
  a 
  rare 
  instance 
  of 
  error, 
  gone 
  to 
  the 
  opposite 
  ex- 
  

   treme, 
  in 
  uniting 
  with 
  O. 
  reticularis, 
  O. 
  araneosa, 
  and 
  O. 
  

   venulata 
  of 
  Lam., 
  and 
  Duclos' 
  species 
  O. 
  Timoria, 
  O. 
  obesina, 
  

   and 
  O. 
  pindarina. 
  Mr. 
  Reeve's 
  fig. 
  16a. 
  represents 
  well 
  the 
  

   common 
  Caribbean 
  species, 
  O. 
  reticularis, 
  which 
  inhabits 
  the 
  

   islands 
  and 
  main 
  land 
  around 
  the 
  Caribbean 
  sea.
