  We 
  enter 
  this 
  with 
  a 
  degree 
  of 
  doubt. 
  Only 
  one 
  specimen 
  occurred, 
  

   which 
  probably 
  belongs 
  to 
  this 
  species, 
  but 
  its 
  condition 
  is 
  not 
  good. 
  

   The 
  type 
  came 
  from 
  Hong-Kong 
  Island 
  (Hinds). 
  Hidalgo 
  mentions 
  

   it 
  as 
  an 
  Australian 
  shell, 
  probably 
  not 
  occurring 
  in 
  the 
  Philippines.

  Young 
  examples

  A 
  very 
  well-marked 
  species, 
  well 
  figured 
  by 
  Ileeve. 
  Originally 
  

   described 
  from 
  the 
  China 
  Sea 
  and 
  Straits 
  of 
  Macassar, 
  found 
  at 
  depth 
  

   of 
  from 
  5-25 
  fathoms. 
  

  

  I 
  may 
  add 
  that 
  Tryon 
  ' 
  is 
  in 
  complete 
  error 
  in 
  attempting 
  to 
  merge 
  

   PL 
  intertincta, 
  Smith, 
  with 
  this 
  species. 
  There 
  could 
  hardly 
  be 
  two 
  

   Drillics 
  more 
  dissimilar. 
  

  

  Hidalgo 
  includes 
  it 
  in 
  his 
  Philippine 
  Catalogue, 
  and 
  Hedley 
  notes 
  

   it 
  from 
  Queensland.

  none 
  

   living,

  and

  basis. 
  

  

  These 
  specimens 
  are 
  placed 
  under 
  spectrum 
  with 
  just 
  a 
  little 
  doubt. 
  

   They 
  agree 
  up 
  to 
  a 
  certain 
  point, 
  and 
  it 
  was 
  thought 
  best 
  to 
  allow 
  

   for 
  a 
  certain 
  percentage 
  of 
  variability. 
  The 
  original 
  examples, 
  

   collected 
  by 
  Mr. 
  Hugh 
  Cuming 
  at 
  Puerto 
  Galero, 
  I. 
  Mindoro, 
  

   Philippines, 
  are 
  described 
  as 
  of 
  thin 
  texture 
  ; 
  also 
  as 
  " 
  a 
  pale 
  oblicj^uely 
  

   plaited 
  shell 
  minutely 
  and 
  delicately 
  ridged 
  across".

  Jask,

  A 
  curious 
  species, 
  isolated 
  in 
  appearance 
  and 
  character. 
  At 
  the 
  

   time 
  of 
  description 
  we 
  compared 
  it 
  with
