  Tate 
  {I. 
  c. 
  supra) 
  states 
  that 
  this 
  species 
  is 
  peculiar 
  to 
  the 
  

   island 
  of 
  St. 
  Lucia, 
  but 
  he 
  does 
  not 
  mention 
  the 
  fact 
  that 
  it 
  

   has 
  been 
  recorded 
  from 
  Trinidad 
  and 
  Demerara. 
  However, 
  

   it 
  is 
  not 
  mentioned 
  by 
  Guppy 
  in 
  his 
  list 
  of 
  the 
  shells 
  of 
  Trini- 
  

   dad 
  ; 
  and 
  Bland 
  (Ann.

   remarks, 
  " 
  I 
  am 
  satisfied 
  that 
  the 
  information 
  afforded 
  by 
  the 
  

   late 
  Mr. 
  McMurray 
  as 
  to 
  the 
  habitat 
  (Trinidad 
  and 
  Deme- 
  

   rara) 
  of 
  B. 
  aulacostylus 
  was 
  incorrect." 
  Until, 
  therefore, 
  its 
  

   occurrence 
  in 
  those 
  two 
  localities 
  receives 
  confirmation 
  it 
  may 
  

   be 
  regarded 
  as 
  restricted 
  to 
  St. 
  Lucia. 
  

  

  The 
  largest 
  specimen 
  collected 
  by 
  Mr. 
  Ramage 
  is 
  43 
  milli- 
  

   metres 
  in 
  length, 
  six 
  longer 
  than 
  the 
  type 
  described 
  by 
  

   Pfeiffer.

  This 
  species 
  is 
  somewhat 
  intermediate 
  in 
  form 
  between 
  B. 
  

   chrysalis, 
  Pfr., 
  and 
  B. 
  martiaicensis, 
  Pfr. 
  It 
  is, 
  however, 
  

   well 
  distinguished 
  by 
  the 
  sculpture 
  of 
  the 
  apical 
  whorls 
  and 
  

   the 
  pilose 
  punctured 
  striae 
  of 
  the 
  rest. 
  The 
  reflexion 
  of 
  the 
  

   columella 
  also 
  is 
  different.
