  "We 
  obtained, 
  under 
  stones, 
  at 
  low 
  water 
  mark, 
  on 
  the 
  reef 
  

   at 
  Panama, 
  two 
  specimens 
  of 
  a 
  species, 
  which 
  appears 
  like 
  a 
  

   small 
  Conus^ 
  but 
  it 
  has 
  stout 
  ribs 
  transverse 
  to 
  the 
  direction. 
  

   It 
  may 
  be 
  a 
  young 
  Columhella, 
  but 
  it 
  is 
  not 
  the 
  young 
  of 
  any 
  

   shell 
  known 
  to 
  us.

   If 
  Dr. 
  Jay's 
  shell 
  is 
  the 
  same 
  as 
  ours, 
  there 
  must 
  be 
  an 
  error 
  

   in 
  his 
  statement 
  of 
  habitat. 
  We 
  collected 
  70 
  specimens, 
  mostly 
  

   at 
  Taboga 
  and 
  partly 
  at

  Shell 
  with 
  a 
  rhomboidal 
  outline 
  : 
  mostly 
  dark 
  brown 
  ; 
  tuber- 
  

   cles 
  mostly 
  white 
  ; 
  with 
  a 
  white 
  fascia 
  next 
  below 
  the 
  peri- 
  

   phery 
  of 
  the 
  last 
  whorl 
  ; 
  with 
  some 
  of 
  the 
  tubercles 
  partly 
  

   rufous 
  : 
  with 
  eight 
  or 
  nine 
  very 
  prominent 
  transverse 
  ridges, 
  

   which 
  are 
  crossed 
  by 
  ten 
  or 
  eleven 
  spiral 
  ridges, 
  of 
  which 
  three 
  

   or 
  four 
  appear 
  on 
  the 
  spire 
  ; 
  with 
  the 
  intersections 
  sharply 
  tuber- 
  

   culous 
  ; 
  with 
  fine 
  spiral 
  striae 
  : 
  apex 
  acute 
  : 
  spire 
  conic 
  : 
  

   whorls 
  eight 
  or 
  nine, 
  convex, 
  with 
  a 
  moderately 
  impressed 
  

   suture 
  : 
  aperture 
  rather 
  long 
  : 
  labrum 
  rather 
  sharp, 
  strength- 
  

   ened 
  by 
  the 
  last 
  ridge, 
  which 
  is 
  very 
  long, 
  scalloped 
  by 
  the 
  

   spiral 
  ridges, 
  with 
  corresponding 
  plaits 
  within 
  : 
  inner 
  lip 
  exca- 
  

   vated

  with 
  a 
  few 
  wrinkles 
  above 
  and 
  granules 
  below 
  ; 
  

   canal 
  moderately 
  long. 
  This 
  species 
  is 
  much 
  like 
  a 
  Murex.
