  The

  The 
  specimens 
  marked 
  by 
  Carpenter 
  as 
  type 
  of 
  Adula 
  stylina 
  Carpenter 
  and 
  preserved 
  

   in 
  the 
  Redpath 
  Museum 
  are 
  from 
  San 
  Diego 
  collected 
  by 
  Hemphill. 
  The 
  lot 
  consists 
  of 
  16 
  

   double 
  specimens. 
  These 
  are 
  not 
  from 
  the 
  two 
  localities, 
  Neah 
  Bay, 
  Washington, 
  or 
  Mon- 
  

   terey, 
  California, 
  mentioned 
  in 
  the 
  original 
  description. 
  Strictly, 
  therefore, 
  these 
  specimens 
  

   are 
  not 
  from 
  the 
  type 
  locality. 
  Hence 
  in 
  choosing 
  a 
  neotype 
  that 
  material 
  from 
  San 
  Diego, 
  

   California, 
  cannot 
  be 
  used. 
  The 
  value 
  of 
  the 
  material 
  is 
  that 
  it 
  was 
  identified 
  and 
  labelled 
  by 
  

   Dr. 
  Carpenter.

  The 
  original 
  description 
  of 
  this 
  species 
  is 
  included 
  in 
  Oldroyd. 
  

   As 
  may 
  be 
  noted 
  by 
  the 
  illustrations 
  of 
  the 
  holotype, 
  the 
  shell 
  of 
  this 
  species 
  is 
  thin 
  and 
  

  

  fragile. 
  There 
  are 
  no 
  teeth, 
  and 
  the 
  hinge 
  line 
  and 
  margins 
  of 
  the 
  shell 
  beneath 
  the 
  beak 
  

  

  are 
  synonymous. 
  The 
  white 
  spongy 
  ossicle 
  inside 
  beneath 
  the 
  beak, 
  extending 
  posteriorly, 
  

  

  may 
  be 
  seen 
  on 
  the 
  holotype, 
  if 
  the 
  shell 
  is 
  tipped.
