  Nothing 
  in 
  Carpenter's 
  writings 
  of 
  this 
  species 
  indicates 
  that 
  the 
  type 
  was 
  a 
  fossil. 
  

   Carpenter's 
  statements 
  concerning 
  the 
  habitat 
  refer 
  to 
  the 
  species 
  as 
  of 
  the 
  Recent. 
  This 
  is 
  

   particularly 
  indicated 
  (1864, 
  p. 
  655) 
  in 
  the 
  column 
  of 
  localities 
  of 
  the 
  species. 
  After 
  B. 
  

   aspcnmi 
  and 
  B. 
  armillatum, 
  fs 
  is 
  attached 
  to 
  the 
  Santa 
  Barbara 
  symbol. 
  This 
  symbol 
  is 
  not 
  

   attached 
  to 
  the 
  localities 
  of 
  B. 
  fastigiatum. 
  Bartsch 
  (1911) 
  presented 
  a 
  composite 
  drawing 
  

   of 
  two 
  specimens 
  in 
  the 
  U. 
  S. 
  National 
  Museum 
  collected 
  by 
  Col. 
  Jewett 
  from 
  Santa 
  Barbara 
  

   and 
  quoted 
  by 
  Bartsch 
  as 
  from 
  the 
  "Lower 
  Pleistocene." 
  Dall, 
  Oldroyd, 
  Grant 
  and 
  Gale, 
  and 
  

   Burch 
  followed 
  Bartsch 
  and 
  repeated 
  the 
  Pleistocene 
  age 
  as 
  original. 
  Bartsch 
  is 
  the 
  authority 
  

   for 
  such 
  an 
  age 
  based 
  on 
  his 
  examination 
  of 
  U. 
  S. 
  National 
  ^Museum 
  specimens, 
  which 
  are 
  

   not 
  types. 
  If 
  the 
  type 
  were 
  found 
  and 
  determined 
  to 
  be 
  fossil 
  such 
  a 
  type 
  locality 
  would 
  be 
  

   valid. 
  

  

  Photographs 
  of 
  two 
  specimens 
  which 
  were 
  ideally 
  figured 
  by 
  Bartsch 
  are 
  included 
  herein. 
  

   They 
  are 
  labelled 
  "Sta. 
  Barbara 
  Jewett". 
  They 
  are 
  not 
  marked 
  types. 
  The 
  type 
  of 
  this 
  species 
  

   has 
  not 
  been 
  found. 
  Oldroyd's 
  statement 
  about 
  the 
  type 
  should 
  be 
  corrected 
  as 
  to 
  place 
  and 
  

   number.
