  This 
  shell 
  has 
  distant 
  fine 
  spiral 
  strife, 
  which 
  are 
  usually 
  

   obsolete 
  on 
  the 
  middle 
  of 
  the 
  whorls. 
  Some 
  specimens 
  are 
  

   ornamented 
  with 
  spiral 
  lines 
  of 
  dark 
  brown, 
  and 
  rarely 
  the 
  

   whole 
  shell, 
  except 
  the 
  aperture, 
  is 
  dark 
  brown. 
  Mr. 
  Powis 
  

   disposes 
  of 
  the 
  coloration 
  with 
  the 
  single 
  word 
  albescenie, 
  but 
  

   otherwise 
  his 
  brief 
  description 
  corresponds 
  exactly 
  with 
  our 
  

   shells.

  The
