  Dall 
  stated 
  (1870, 
  p.

  that 
  the 
  type 
  of 
  this 
  species 
  was 
  in 
  the 
  Smithsonian 
  Institution, 
  

   No. 
  11847. 
  He 
  made 
  a 
  careful 
  study 
  of 
  the 
  type 
  and 
  decided 
  that 
  it 
  was 
  an 
  "abnormally 
  

   elevated, 
  dead 
  and 
  faded" 
  shell 
  of 
  W. 
  peltoides.

  of 
  this

  was 
  once 
  in

  Carpenter 
  described 
  this 
  species 
  from 
  Mazatlan, 
  and 
  therefore 
  the 
  figuring 
  of 
  the 
  type 
  

   belongs 
  with 
  the 
  illustration 
  of 
  the 
  catalogue 
  of 
  the 
  Mazatlan 
  Mollusca 
  (Carpenter, 
  1857). 
  

   The 
  type 
  should 
  be 
  in 
  the 
  British 
  MuseuuL 
  In 
  papers 
  by 
  Carpenter 
  in
