  be 
  more 
  common 
  than 
  the 
  variety 
  figured 
  by 
  Reeve 
  (fig, 
  152a), 
  which 
  

   does 
  not 
  represent 
  the 
  full 
  dimensions 
  of 
  the 
  species. 
  The 
  largest 
  

   specimen 
  in 
  the 
  Museum 
  is 
  45 
  millim. 
  high 
  and 
  40 
  millim. 
  in

  The 
  sculpture 
  of 
  this 
  species 
  resembles 
  that 
  of 
  the 
  young 
  of 
  P. 
  

   asperrimus, 
  consisting 
  of 
  numerous 
  fine 
  costas 
  bordered 
  on 
  each 
  

   side 
  by 
  a 
  much 
  finer 
  and 
  less 
  elevated 
  one, 
  and 
  all 
  bearing 
  prickly 
  

   scales. 
  The 
  interior 
  is 
  pale 
  olive, 
  with 
  paler 
  radiating 
  grooves 
  and 
  

   a 
  purplish 
  border 
  all

  The 
  colouring 
  of 
  Sowerby's 
  figure 
  is 
  ridiculous, 
  the 
  yellow 
  ground- 
  

   colour 
  being 
  purely 
  imaginary. 
  The 
  type 
  is 
  whitish 
  towards 
  the 
  

   umbones, 
  but 
  light 
  purplish 
  red 
  elsewhere, 
  rayed 
  with 
  a 
  much 
  

   darker 
  tint, 
  the 
  rays 
  being 
  narrower 
  than 
  as 
  depicted 
  in 
  the 
  

   figure. 
  

  

  The 
  single 
  specimen 
  from 
  Torres 
  Straits 
  has 
  the 
  ground-colour 
  

   light 
  purplish 
  red 
  like 
  the 
  type, 
  but 
  the 
  slightly 
  elevated 
  rays 
  are 
  

   white 
  instead 
  of 
  being 
  darker.
