  record 
  

  

  This 
  species 
  was 
  described 
  from 
  Mazatlan. 
  The 
  illustration 
  and 
  discussion 
  are 
  reserved 
  

   for 
  the 
  work 
  on 
  that 
  fauna. 
  The 
  synonymy 
  is 
  not 
  intended 
  to 
  be 
  complete, 
  except 
  to 
  point 
  

   out 
  references 
  where 
  the 
  species 
  has 
  been 
  recorded 
  from 
  Monterey. 
  Some 
  of 
  the 
  records 
  are 
  

   compilation 
  and 
  do 
  not 
  include 
  original 
  findings. 
  Smith

  its 
  existence 
  at 
  

   Monterey.
