  The 
  operculum 
  of 
  this 
  species 
  resembles 
  that 
  of 
  Purpura. 
  The 
  

   species 
  is 
  rather 
  variable 
  in 
  form,

  of

  length 
  of 
  the 
  basal

  anterior 
  canal. 
  

  

  The 
  typical 
  form 
  is 
  rather 
  longer, 
  and 
  has 
  a 
  more 
  prolonged 
  canal 
  

   than 
  the 
  variety 
  from 
  Japan, 
  has 
  more 
  brown 
  colouring, 
  and 
  an 
  

   additional 
  longitudinal 
  rib. 
  All 
  have 
  from 
  seven 
  to 
  eight

  and 
  crenulated

  This 
  speciesis 
  represented 
  in 
  the 
  present 
  collection 
  by 
  a 
  single 
  

   specimen 
  : 
  and 
  it 
  is 
  remarkable 
  on 
  account 
  of 
  the 
  peculiarity 
  of 
  its 
  

   colour, 
  its 
  small 
  size, 
  and
