  One 
  specimen 
  dredged, 
  according 
  to 
  the 
  author' 
  of 
  the 
  species, 
  in 
  

   all 
  respects 
  similar 
  to 
  the 
  type 
  from 
  the 
  Philippine 
  Isles 
  excepting' 
  

   that 
  the 
  spire 
  is 
  a 
  little 
  shorter. 
  I 
  have 
  neither

  this 
  nor 
  can 
  

   I

  its

  Our

  of 
  the

  also 
  found 
  it 
  plentiful 
  in 
  Celebes 
  and 
  at 
  Malacca, 
  from 
  7 
  to 
  

   22 
  fathoms. 
  Our 
  examples 
  vary 
  in 
  body-colour 
  from 
  shining 
  white 
  

   to 
  umber-brown. 
  All 
  are 
  very 
  shining, 
  and, 
  as 
  Reeve 
  remarks, 
  it 
  is 
  

   " 
  a 
  characteristic 
  and 
  well-defined 
  species 
  ". 
  It 
  appears 
  in 
  Hedley's 
  

   Queensland 
  list, 
  and 
  likewise 
  in 
  that 
  of 
  Hidalgo,

  It

  a 
  well-marked 
  shell. 
  This, 
  and 
  

   perhaps 
  tiitens 
  also, 
  might 
  with 
  propriety 
  be 
  transferred
