  This 
  species 
  was 
  described 
  from 
  Cape 
  San 
  Lucas. 
  The 
  type 
  was 
  figured 
  by 
  Dall 
  and 
  

   Bartsch 
  (in 
  Arnold) 
  and 
  in 
  their 
  later 
  monograph 
  (1909). 
  Although 
  Arnold 
  indicated 
  that 
  

   the 
  species 
  was 
  living 
  from 
  Cape 
  San 
  Lucas 
  north 
  to 
  San 
  Pedro, 
  such 
  distribution 
  appar- 
  

   ently 
  was 
  not 
  verified. 
  Arnold 
  also 
  included 
  the 
  species 
  in 
  the 
  Pleistocene 
  of 
  San 
  Diego. 
  

   Jordan 
  (1924) 
  stated 
  that 
  the 
  northern 
  range 
  extended 
  to 
  San 
  Diego. 
  On 
  Jordan's 
  authority. 
  

   Keen 
  and 
  Burch 
  include 
  the 
  species 
  in 
  the 
  southern 
  California 
  fauna. 
  The 
  discussion 
  and 
  

   synonymy 
  are 
  not 
  intended 
  to 
  be 
  complete 
  in
