  This 
  species 
  to 
  the 
  naked 
  eye 
  appears 
  to 
  he 
  almost 
  uniformly 
  

   light 
  pink 
  ; 
  by 
  the 
  aid 
  of 
  a 
  lens, 
  however, 
  it 
  is 
  seen 
  to 
  be 
  coloured 
  

   as 
  described 
  above, 
  and 
  in 
  addition 
  there 
  are 
  two 
  or 
  three 
  white 
  

   dots 
  placed 
  at 
  distant 
  intervals 
  upon 
  the 
  upper 
  margin 
  of 
  the 
  

   whorls.

  The 
  specimen 
  from 
  this 
  locality 
  is 
  shorter 
  than 
  that 
  figured 
  by 
  

   Eeeve, 
  and 
  almost 
  as 
  stout 
  as 
  N. 
  mucronata, 
  A. 
  Adams, 
  which 
  is 
  

   very 
  closely 
  allied.

  The 
  little 
  shell 
  from 
  the 
  above 
  island 
  resembles 
  in 
  every 
  particular 
  

   N. 
  densigranata, 
  said 
  to 
  have 
  been 
  originally 
  found 
  at 
  the 
  Philijipine 
  

   Islands, 
  and 
  which 
  T 
  think 
  should 
  be 
  regarded 
  as 
  a 
  dwarf 
  form 
  of 
  

   N. 
  stir/maria. 
  This 
  species 
  I 
  have 
  elsewhere 
  quoted 
  from 
  the 
  Korean 
  

   Straits.

  The 
  same 
  shell, 
  regarded 
  by 
  Martens 
  as 
  a 
  variety 
  (r-hodostoma) 
  of 
  

   P. 
  tewtvs 
  of 
  Gmelin 
  (Moll. 
  Mauritius, 
  p. 
  241, 
  pi. 
  20. 
  f.

  was 
  

   dredged 
  by 
  Prof. 
  Mcibius 
  at 
  five 
  fathoms 
  depth 
  at 
  the 
  Seychelles, 
  

   The 
  sculpture 
  is 
  of 
  a 
  more 
  delicate 
  character 
  than 
  obtains 
  in 
  

   P. 
  textas, 
  and 
  the 
  spire 
  is 
  more 
  graceful.
