  The 
  shells 
  before 
  us 
  seem 
  to 
  be 
  intermediate 
  between 
  this 
  

   species 
  and 
  F. 
  riigosa 
  Sowb., 
  as 
  these 
  species 
  are 
  figured 
  by 
  

   Sowerby 
  and 
  by 
  Reeve. 
  AVe 
  are 
  indebted 
  to 
  Mr. 
  Cuming 
  for 
  

   specimens 
  which 
  enable 
  us 
  to 
  determine 
  the 
  species.
