  Tlie 
  two

  whorls 
  are 
  fleshy 
  pink

   and 
  the 
  radiating

  with 
  fine

  This 
  species 
  is 
  very 
  nearly 
  related 
  to 
  D. 
  octogomun 
  of 
  Lamarck. 
  

   The 
  eight 
  ridges 
  are 
  conspicuously 
  acute, 
  the 
  interstices 
  being 
  

   flattish, 
  and 
  marked 
  only 
  with 
  cross 
  lines 
  or 
  striae 
  of 
  growth. 
  The 
  

   colour 
  of 
  this 
  shell 
  is 
  white, 
  varying 
  to 
  pale 
  green.

  For 
  full 
  synonymy 
  of 
  this 
  species 
  I 
  would 
  refer 
  the 
  reader 
  to 
  a 
  

   paper 
  by 
  the 
  author 
  on 
  this 
  genus 
  in 
  the 
  'Journal 
  of 
  Conchology,' 
  vol. 
  ii. 
  

   pp. 
  252-264. 
  The 
  animals 
  from 
  the 
  above 
  locality 
  are 
  yellowish 
  or, 
  

   buif, 
  copiously 
  blotched 
  and 
  stained 
  irregularly 
  with 
  blackish 
  grey, 
  

   the 
  sole 
  of 
  the 
  foot 
  being 
  of 
  a 
  uniform 
  buff 
  tint. 
  The 
  shells 
  are 
  of 
  

   the 
  same 
  width 
  (13 
  millim.) 
  ; 
  but 
  one 
  of 
  them 
  is 
  2o 
  millim. 
  long, 
  the 
  

   other 
  only 
  23|, 
  which 
  gives 
  to 
  the 
  former 
  a 
  more 
  elongate 
  appear-

  •This 
  species 
  may 
  be 
  recognized 
  by 
  the 
  elevated 
  squamous 
  character 
  

   of 
  the 
  radiating 
  ridges, 
  which 
  are 
  more 
  or 
  less 
  tinted 
  with 
  pale 
  rose. 
  

   In 
  the 
  young 
  state 
  the 
  apex 
  is 
  more 
  conical 
  than 
  in 
  older 
  shells, 
  and 
  

   the 
  foramen 
  (as 
  is 
  usually 
  the 
  case 
  in 
  immature 
  specimens 
  of 
  this 
  

   genus) 
  is 
  more 
  central.
