  it 
  were 
  separated 
  from 
  the 
  other 
  species 
  without 
  the 
  slightest 
  

   difficulty. 
  

  

  It 
  is 
  smaller 
  than 
  P. 
  Capennis^ 
  the 
  only 
  species 
  it 
  can 
  be 
  compared 
  

   with, 
  is 
  different 
  in 
  form, 
  and 
  the 
  style 
  of 
  coloration 
  is 
  also 
  different. 
  

   The 
  general 
  outline 
  is 
  more 
  ovate, 
  the 
  spire 
  shorter, 
  the 
  body-whorl 
  

   larger 
  in 
  proportion 
  to 
  the 
  rest 
  of 
  the 
  shell, 
  and 
  the 
  aperture 
  is 
  also 
  

   larger 
  and 
  almost 
  patulate. 
  It 
  is 
  difficult 
  to 
  describe 
  the 
  colour. 
  It 
  

   consists 
  of 
  reddish-brown 
  and 
  creamy 
  or 
  white 
  undulating 
  lines, 
  the 
  

   reddish-brown 
  colour 
  usually 
  predominating. 
  The 
  white 
  markings 
  

  

  are 
  most 
  conspicuous 
  below 
  the 
  suture 
  on 
  the 
  body-whorl, 
  and 
  they 
  

   are 
  very 
  frequently 
  bordered 
  on 
  their 
  anterior 
  margin 
  with 
  dark 
  

   brown, 
  in 
  some 
  specimens 
  in 
  the 
  form 
  of 
  spots. 
  The 
  apex 
  of 
  the 
  spire 
  

   is 
  pale 
  and 
  pellucid, 
  and 
  sometimes 
  the 
  penultimate 
  whorl 
  is 
  almost 
  

   without 
  colour 
  - 
  markings, 
  being 
  uniformly 
  corneous. 
  In 
  a 
  few 
  

   specimens 
  the 
  reddish-brown 
  colour 
  is 
  replaced 
  by 
  a 
  dark 
  purple- 
  

   brown 
  tint. 
  The 
  dimensions 
  given 
  are 
  those 
  of 
  an 
  average-size 
  

   example. 
  The 
  largest 
  specimen 
  observed 
  is 
  6 
  mm. 
  in 
  length. 
  I 
  have 
  

   named 
  this 
  species 
  after 
  Ur.
