  Mr.

  reference 
  to 
  Proc. 
  Z. 
  S., 
  1841, 
  for 
  Sowerby's 
  

   description 
  is 
  evidently 
  a 
  misprint 
  for 
  1833 
  ; 
  and 
  the 
  reference 
  

   to 
  the 
  same 
  work, 
  1845, 
  for 
  C. 
  rostrum 
  seems 
  erroneous.

   Hanley 
  's 
  reference 
  to

  Conch.
