  to 
  K. 
  ornatissima, 
  Bens./ 
  but 
  that 
  species 
  has 
  tlie 
  costulse 
  placed 
  

   much 
  closer 
  tocether. 
  

  

  Two 
  of 
  the 
  specimens 
  are 
  larger 
  than 
  tlie 
  type, 
  measuring: 
  diam.

  I 
  have 
  much 
  pleasure 
  in 
  associating 
  Mr. 
  Fulton's 
  name 
  with 
  this 
  

   interesting 
  new 
  species. 
  

  

  Plectotuopis 
  chondrodeema, 
  var. 
  subinflata, 
  n. 
  

  

  Differs 
  from 
  the 
  type 
  in 
  being 
  smaller 
  and 
  paler 
  in 
  colour 
  and 
  in 
  

   having 
  a 
  narrower 
  umbilicus, 
  while 
  the 
  last 
  whorl 
  is 
  more 
  swollen 
  

   and 
  rounded 
  at 
  the 
  periphery, 
  which 
  in 
  the 
  type 
  is 
  subangulate.

  British 
  Museum. 
  

  

  The 
  typical 
  forui, 
  described 
  from 
  Annam,'^ 
  never 
  having 
  been 
  

   illustrated, 
  I 
  have 
  much 
  pleasure 
  in 
  giving 
  a 
  figure 
  of 
  this 
  

   geographical 
  race. 
  Mr. 
  Fulton 
  informs 
  me 
  that 
  he 
  received 
  the 
  

   shells 
  as 
  P. 
  subinflata^ 
  Mabille, 
  but 
  although 
  this 
  name 
  has 
  never 
  

   been 
  published 
  I 
  have 
  embodied 
  it, 
  since 
  it 
  may 
  have 
  been 
  distributed, 
  

   so 
  labelled, 
  to 
  other 
  collectors.
