  We 
  abstain 
  from 
  describing 
  this 
  species, 
  because 
  the 
  only 
  

   two 
  specimens 
  which 
  we 
  have 
  are 
  immature. 
  They 
  resem- 
  

   ble 
  O. 
  -variabilis., 
  but 
  the 
  general 
  form 
  and 
  the 
  aperture 
  are 
  

   wider, 
  and 
  the 
  shells 
  are 
  covered 
  with 
  excessively 
  minute 
  re- 
  

   volving 
  striae. 
  Except 
  in 
  being 
  striated, 
  they
