  The 
  type 
  material 
  consists 
  of 
  five 
  specimens 
  labelled 
  "Cotypes 
  Jevvett 
  Sta. 
  Barbara." 
  One 
  

   of 
  the 
  specimens 
  has 
  a 
  rough 
  surface 
  and 
  an 
  operculum. 
  This 
  individual 
  is 
  not 
  consistent 
  with 
  

   Carpenter's 
  original 
  description, 
  as 
  he 
  stated 
  tliat 
  the 
  operculum 
  was 
  unknown. 
  Woodring 
  

   made 
  the 
  same 
  observation 
  and 
  inserted 
  a 
  pencil 
  note 
  to 
  the 
  same 
  effect 
  with 
  the 
  type 
  lot. 
  

  

  The 
  specimen 
  figured 
  herein 
  has 
  a 
  Iirown 
  line 
  just 
  below 
  and 
  at 
  the 
  suture 
  and 
  continues 
  

   on 
  the 
  body 
  whorl 
  along 
  the 
  same 
  spiral 
  line 
  (carina). 
  The 
  carina 
  is 
  sharp. 
  All 
  of 
  the 
  other 
  

   three

  are 
  keeled

  they
