  The 
  shell 
  descrihed

   that 
  author

  1772-3) 
  is 
  very 
  

   much 
  more 
  slender 
  than 
  the 
  form 
  referred 
  to 
  it 
  by 
  the 
  two 
  above- 
  

   mentioned 
  writers, 
  and 
  has 
  simple 
  non-coronated 
  margins 
  to 
  the 
  

   whorls 
  of 
  the 
  spire. 
  

  

  The 
  C. 
  acutangulus 
  of 
  Kiener 
  difi'ers 
  from 
  the 
  typical 
  form 
  of 
  

   C. 
  turrk'ulatus 
  merely 
  in 
  being 
  more 
  brightly 
  coloured.

  acutangidus, 
  Eeeve 
  (Conch. 
  Icon. 
  pi. 
  37. 
  fig.

  appears 
  

   to 
  be 
  a 
  third 
  species, 
  and 
  although 
  agreeing 
  with 
  Kiener 
  s 
  shell 
  

   as 
  regards 
  form, 
  diflPers 
  in 
  having 
  a 
  smooth 
  non-tuberculated 
  spire.

  is 
  unques- 
  

   tionably 
  merely 
  a 
  slight 
  variety 
  of 
  this

  and 
  

   bears 
  no 
  relationship 
  whatever 
  to
