  A 
  whitish-ochre 
  species, 
  twelve 
  or 
  thirteen 
  whorled, 
  sub-pellucid, 
  

   with 
  ventricose 
  whorls, 
  straightly 
  longitudinally 
  costate, 
  and 
  with 
  

   smooth 
  interstices, 
  ribs 
  few 
  in 
  number, 
  about 
  twelve 
  on 
  body-whorl. 
  

   The 
  nuclear 
  whorls 
  are 
  pupiform 
  and 
  expanded, 
  so 
  that 
  it 
  should 
  be 
  

   placed 
  in 
  the 
  sub-genus 
  JVisiUirris, 
  D. 
  & 
  B. 
  I 
  had 
  considered 
  T. 
  icela 
  

   the 
  same 
  species, 
  and 
  am 
  obliged 
  for 
  Mr. 
  Edgar 
  Smith's 
  opinion 
  in 
  

   this 
  matter. 
  All 
  the 
  localities 
  given 
  by 
  me 
  in 
  a 
  subsequent 
  paper 
  ^ 
  

   should 
  be 
  removed, 
  therefore, 
  with 
  the 
  exception 
  of 
  Bombay, 
  to 
  which 
  

   locality 
  this 
  species 
  is 
  at 
  present 
  confined. 
  It 
  appears, 
  however, 
  to 
  be 
  

   the 
  commonest 
  form 
  found 
  there.
