  Originally 
  described 
  from 
  Formosa. 
  

  

  Judging 
  by 
  the 
  Indian 
  examples, 
  this 
  hardly 
  differs 
  from 
  the 
  variety 
  

   violacea 
  (Hinds), 
  excepting 
  in 
  the 
  pure-white 
  coloration, 
  all 
  the 
  violacea 
  

   I 
  have 
  seen 
  being 
  most 
  delicately 
  tinted 
  the 
  palest 
  lilac.

  Inside 
  the 
  harbour 
  in 
  3-7 
  fathoms, 
  loose 
  stones 
  

   and 
  mud. 
  

  

  It 
  is 
  reported 
  to 
  range 
  from 
  the 
  Red 
  Sea 
  to 
  Japan, 
  Philippine 
  

   Isles, 
  and 
  Australia. 
  The 
  type 
  figui'ed 
  by 
  Reeve 
  came 
  from 
  the 
  

   north 
  coast 
  of 
  New 
  Guinea 
  and 
  Macassar 
  Straits, 
  7-22 
  fathoms. 
  

   It 
  is 
  therefore 
  in 
  all 
  probability 
  widely 
  distributed 
  over 
  the 
  whole 
  

   eastern 
  tropics. 
  I 
  am 
  sorry 
  it 
  cannot 
  be 
  taken 
  as 
  the 
  more 
  typical 
  

   form 
  ; 
  but 
  the 
  name 
  had 
  been 
  previously 
  employed, 
  by 
  Mighels 
  and 
  

   C. 
  B. 
  Adams, 
  so 
  was 
  rendered 
  untenable. 
  2\ 
  nivea 
  proper 
  is, 
  in 
  my 
  

   opinion, 
  only 
  the 
  same 
  shell 
  without 
  the 
  pale 
  lilac 
  tint.

  Originally 
  described 
  from 
  Aden, 
  this 
  variety 
  merges 
  on 
  the 
  one 
  

   hand 
  into 
  the 
  type, 
  and 
  on 
  the 
  other 
  approximates 
  pouloensis, 
  Jouss. 
  

   This 
  latter, 
  however, 
  is 
  a 
  stouter 
  shell, 
  of 
  a 
  uniform 
  dun 
  colour, 
  but, 
  

   notwithstanding 
  this, 
  it 
  is 
  probably 
  only 
  another 
  variety 
  of 
  nivea. 
  

  

  PI. 
  makemonos 
  is 
  known 
  by 
  its 
  pale-brown 
  hue, 
  with 
  longitudinal 
  

   patches 
  of 
  a 
  darker 
  shade 
  crossing 
  it 
  at 
  intervals. 
  

   It 
  is 
  also 
  reported 
  from 
  Japan.
