  This 
  may 
  be 
  a 
  monstrosity, 
  but 
  it 
  is 
  very 
  regular 
  in 
  its 
  formation; 
  

   the 
  deep 
  ridge 
  round 
  the 
  dorsal 
  base 
  of 
  the 
  body-whorl 
  is 
  a 
  

   characteristic 
  worth 
  attention.

  Slight 
  doubt 
  accompanies 
  this 
  determination, 
  for 
  the 
  only 
  three 
  

   examples 
  seen 
  were 
  in 
  very 
  poor 
  condition.

  Since 
  the 
  original 
  description 
  was 
  penned 
  I 
  have 
  seen 
  some 
  

   brighter-coloured 
  examples, 
  tinged 
  with 
  yellow-ochreous. 
  The 
  

   mouth 
  is 
  particularly 
  wide, 
  and 
  the 
  sinus 
  well 
  expressed. 
  Apical 
  

   whorls 
  obscurely 
  striate, 
  the 
  acme 
  itself 
  being 
  smooth 
  and 
  vitreous.
