  Remarks. 
  — 
  The 
  two 
  brown 
  bands 
  and 
  single 
  tooth 
  of 
  this 
  species, 
  

   together 
  with 
  the 
  absence 
  of 
  an 
  umbilicus, 
  may 
  serve 
  to 
  distinguish 
  it. 
  

   The 
  superior 
  termination 
  of 
  the 
  lip 
  is 
  bent 
  down 
  towards 
  the 
  base 
  of 
  the 
  

   columella. 
  It 
  is 
  supposed 
  to 
  be 
  from 
  the 
  collection 
  of 
  Mr 
  Shillaber.

  Remarks. 
  — 
  In 
  its 
  aperture 
  this 
  species 
  has 
  a 
  strong 
  resemblance 
  to 
  

   a 
  Cyclostoma. 
  The 
  superior 
  and 
  inferior 
  portions 
  of 
  the 
  lip 
  do 
  not, 
  

   however, 
  join 
  by 
  one-fifth 
  of 
  a 
  circle 
  — 
  the 
  resemblance 
  is 
  strong 
  in
