  This 
  species 
  was 
  described 
  by 
  Carpenter 
  from 
  Mazatlan. 
  The 
  types 
  (1 
  specimen 
  and 
  2 
  

   valves) 
  should 
  be 
  in 
  the 
  British 
  Museum 
  (Natural 
  History). 
  The 
  figuring 
  of 
  the 
  species 
  

   belongs 
  with 
  the 
  illustration 
  of 
  the 
  types 
  of 
  the 
  Mazatlan 
  Catalogue 
  and 
  is 
  not 
  included 
  

   herein. 
  The 
  brief 
  discussion 
  is 
  inserted 
  because 
  the 
  range 
  of 
  the 
  species 
  has 
  been 
  extended 
  

   to 
  Unalaska, 
  Alaska 
  (Dall).

  This 
  species 
  is 
  another 
  of 
  which 
  the 
  radula 
  only 
  was 
  described 
  first 
  by 
  Dall.

   the 
  manuscript 
  name 
  of 
  Cari>enter 
  as 
  did 
  Tilshry 
  later 
  (1892).
