  Oldroyd 
  (1927) 
  published 
  a 
  copy 
  of 
  Carpenter's 
  description 
  (1865). 
  The 
  measurements 
  

   given

  be 
  corrected

  Bartsch 
  analyzed 
  the 
  characters 
  of 
  the 
  species 
  and 
  distribution 
  and 
  included 
  a 
  figure 
  of 
  

   one 
  of 
  the 
  four 
  syntypes. 
  Those 
  specimens 
  have 
  the 
  label 
  "Monterey

  It 
  is, 
  tlierefore, 
  

   impossible

  the 
  specimens.

  Oldroyd 
  (1927) 
  republished

  after 
  "normalibus"

  correct

  The 
  following 
  lines 
  should 
  be 
  added 
  to

  [Carpenter,

  Bartsch 
  discussed 
  this 
  species 
  and 
  illustrated 
  the 
  holotype. 
  That 
  specimen 
  according 
  to 
  the 
  

   label 
  was 
  collected 
  by 
  Cooper 
  at 
  San 
  Diego. 
  This 
  does 
  not 
  coincide 
  with 
  Carpenter's 
  state- 
  

   ment 
  that 
  the 
  San 
  Diego 
  specimens 
  were 
  collected 
  by 
  Cassidy 
  and 
  that 
  Cooper's 
  specimen 
  

   came 
  from 
  San 
  Pedro. 
  Therefore, 
  one 
  cannot 
  tell 
  whether 
  the 
  locality 
  or 
  the 
  collector 
  on 
  the 
  

   label 
  is 
  incorrect 
  or 
  whether 
  the 
  confusion 
  was 
  made 
  by 
  Carpenter 
  in 
  his 
  description.
