  pronounced 
  pupiform 
  nuclear 
  whorls 
  distinguish 
  it 
  from 
  its 
  congeners. 
  

   It 
  evidently 
  belongs 
  to 
  the 
  sub-genus 
  Nisiturris, 
  Dall 
  & 
  Bartsch. 
  

   I 
  am 
  obliged 
  to 
  Mr. 
  Edgar 
  Smith 
  for 
  first 
  calling 
  my 
  attention 
  to 
  the 
  

   distinctness 
  of 
  this 
  species 
  from 
  sororia.

  Quoting 
  from 
  the 
  original 
  description, 
  this 
  shell 
  exhibits 
  a 
  peculiarity 
  

   in 
  the 
  presence 
  of 
  pseudo-varices, 
  these 
  being 
  simply 
  unequally 
  

   effuse 
  longitudinal 
  ribs. 
  The 
  whole 
  surface 
  of 
  the 
  shell 
  is 
  remarkably 
  

   smooth, 
  white, 
  and 
  shining, 
  the 
  mouth 
  a 
  perfect 
  oval, 
  and 
  the 
  hetero- 
  

   strophe 
  nuclear 
  whorls 
  glassy, 
  globular, 
  and 
  completely 
  reversed. 
  

   It 
  is 
  a 
  rare 
  species, 
  and 
  we 
  have 
  not 
  seen 
  more 
  than 
  twenty 
  specimens.

  A 
  species 
  as 
  yet 
  rarely 
  found, 
  yellowish 
  in 
  hue, 
  with 
  almost 
  straight

  A

  small 
  rufous 
  species, 
  though 
  a 
  few 
  specimens 
  have 
  occurred 
  

   pure

  The 
  ribs 
  are 
  nearly 
  straight, 
  acute, 
  crowded, 
  interstitially 
  

   closely 
  striatulate. 
  The 
  whorls 
  are 
  9-10, 
  with 
  apex 
  bulbous, 
  rufous, 
  

   impressed 
  at 
  the 
  sutures, 
  and 
  tumescent. 
  It 
  only 
  occurred

  This 
  so 
  exactly 
  resembles 
  a 
  Pyrgulina 
  with 
  a 
  simple 
  columella, 
  

   however, 
  that 
  I 
  suggested 
  seven 
  years 
  ago 
  its 
  removal 
  to 
  that 
  genus.
