  Cooper's 
  collection 
  for 
  tiie 
  State 
  Geological 
  Survey 
  of 
  California 
  (1864e, 
  p. 
  155). 
  The 
  

   type 
  material 
  in 
  the 
  U. 
  S. 
  National 
  Museum 
  consists 
  of 
  eight 
  specimens 
  which 
  bear 
  a 
  label, 
  

   "San 
  Pedro. 
  Cooper" 
  and 
  on 
  the 
  back 
  of 
  the 
  label, 
  "15668 
  Cp 
  581." 
  The 
  number 
  appears 
  to 
  

   be 
  Cp 
  581, 
  but 
  it 
  probably 
  should 
  be 
  "Cp 
  587," 
  the 
  original 
  number 
  published 
  by 
  Carpenter. 
  

  

  Arnold's 
  (1903) 
  figure 
  does 
  not 
  represent 
  this 
  species. 
  Perhaps 
  the 
  drawing 
  was 
  not 
  well 
  

   executed. 
  At 
  least 
  it 
  should 
  not 
  be 
  used 
  for 
  identification.

  This 
  species 
  was 
  originally 
  described 
  from 
  the 
  Reigen 
  Mazatlan 
  Collection 
  but 
  it 
  was 
  

   later 
  reported 
  from 
  the 
  Farallon 
  Islands 
  by 
  Carpenter 
  (1864b, 
  p. 
  628, 
  637). 
  The 
  illustration 
  

   of 
  the 
  type 
  belongs 
  in 
  the 
  work 
  on 
  the 
  figuring 
  of 
  tlie 
  Alazatlan 
  Catalogue. 
  Turner

  of 
  the 
  Pholadidae,
