  PROCEEDINGS 
  OF 
  THE 
  M 
  ALACOLOGICAL 
  SOCIETY. 
  

  

  Differing 
  from 
  the 
  last 
  species 
  by 
  its 
  smooth 
  apical 
  whorls, 
  more 
  

   convex 
  lower 
  whorls, 
  and 
  more 
  deeply 
  impressed 
  though 
  less 
  

   crenellated 
  sutures 
  ; 
  the 
  sculpture 
  also 
  has 
  a 
  much 
  more 
  decussate 
  

   appearance, 
  and 
  the 
  columella 
  is 
  more 
  obliquely 
  truncate, 
  while 
  

  

  being 
  diffused 
  above 
  into 
  a 
  callus, 
  which 
  is 
  not 
  the 
  case 
  with 
  Itiopiana 
  

   Meneleki. 
  In 
  the 
  only 
  specimens 
  which 
  I 
  have 
  seen 
  the 
  outer 
  lip 
  

   is 
  broken, 
  but 
  I 
  think 
  that 
  there 
  is 
  no 
  doubt 
  that 
  when 
  intact 
  it 
  is 
  

   single 
  and 
  acute.

  Shell 
  differing 
  from 
  the 
  two 
  preceding 
  species 
  in 
  its 
  smaller 
  size 
  

   and 
  more 
  slender 
  and 
  graceful 
  form 
  ; 
  it 
  possesses 
  but 
  10| 
  whorls, 
  and 
  

  

  the 
  sutures 
  are 
  margined.
