  The 
  holotype 
  of 
  this 
  species 
  has 
  not 
  been 
  found. 
  Oldroyd's 
  statement 
  that 
  the 
  type 
  (origi- 
  

   nal) 
  is 
  in 
  the 
  U. 
  S. 
  National 
  Museum 
  is 
  not 
  correct. 
  If 
  other 
  conditions 
  are 
  equal, 
  the 
  type 
  

   locality 
  depends 
  on 
  whether 
  one 
  accepts 
  Carpenter's 
  (1864b) 
  lines 
  as 
  adequate 
  and 
  the 
  

   original 
  description. 
  If 
  so, 
  Lower 
  California 
  or 
  San 
  Diego 
  would 
  be 
  the 
  type 
  locality. 
  Car- 
  

   penter's 
  (1865) 
  description 
  adds 
  "San 
  Pedro." 
  He 
  did 
  not 
  give 
  measurements. 
  Strong 
  (1930) 
  

   figured 
  the 
  specimen, 
  U. 
  S. 
  National 
  Museum, 
  no. 
  19510, 
  which 
  had 
  been 
  collected 
  by 
  Cooper 
  

   from 
  San 
  Pedro 
  and 
  suggested 
  that 
  this 
  specimen 
  might 
  be 
  the 
  one 
  Carpenter 
  had 
  available 
  

   (1865). 
  This 
  deduction 
  seems 
  reasonable, 
  and 
  in 
  lieu 
  of 
  a 
  holotype 
  or 
  other 
  syntypic 
  ma- 
  

   terial 
  this 
  specimen 
  is 
  the 
  proper 
  shell 
  to 
  be 
  chosen 
  as 
  a 
  lectotype. 
  The 
  writer 
  therefore 
  

   chooses 
  U. 
  S.

  Museum, 
  no. 
  19510 
  (Strong, 
  1930,

  as 
  the 
  lectotype 
  of 
  

   E. 
  tinctum 
  Carpenter. 
  Durham 
  (1937) 
  would 
  have 
  had 
  to 
  go 
  through 
  the 
  same 
  process 
  of 
  

   selection 
  to 
  have 
  determined 
  the 
  type 
  locality 
  as 
  San 
  Pedro. 
  

  

  Strong 
  discussed 
  this 
  species 
  thoroughly 
  as 
  to 
  characters 
  and 
  literature. 
  He 
  figured 
  the 
  

   lectotype, 
  and 
  a

  is 
  therefore 
  not 
  included
