  Pteroplatea 
  crebripunctata 
  Peters, 
  Monatsber, 
  Beri. 
  Akad, 
  1869, 
  703. 
  This 
  species 
  

   is 
  very 
  common 
  in 
  the 
  Gulf 
  of 
  California. 
  It 
  is 
  thus 
  described 
  by 
  Dr. 
  Peters 
  : 
  

  

  Breadth 
  of 
  disk 
  twice 
  the 
  distance 
  from 
  tip 
  of 
  snout 
  to 
  vent. 
  Snout 
  with 
  a 
  blunt 
  

   projection 
  ; 
  anterior 
  margin 
  of 
  pectorals 
  undulate, 
  convex 
  anteriorly 
  and 
  posteriorly, 
  

   medially 
  weakly 
  concave 
  ; 
  outer 
  angle 
  sharply 
  rounded 
  ; 
  posterior 
  margins 
  weakly 
  

   convex, 
  the 
  posterior 
  angle 
  rounded, 
  covering 
  outer 
  half 
  of 
  base 
  of 
  ventrals 
  ; 
  spiracle 
  

   without 
  tentacle 
  ; 
  tail 
  (mutilated) 
  with 
  a 
  low 
  fold 
  on 
  its 
  upper 
  edge. 
  Brown 
  above, 
  

   with 
  thick-set 
  black 
  points 
  ; 
  a 
  row 
  of 
  small, 
  close-set 
  yellow 
  spots 
  on 
  front 
  ofdisk 
  ; 
  

   under 
  side 
  yellowish. 
  

  

  I 
  have 
  compared 
  specimens 
  of 
  this 
  species 
  with 
  P. 
  maclura 
  and 
  P. 
  marmorata, 
  anil 
  

   regard 
  the 
  three 
  as 
  unquestionably 
  distinct, 
  although 
  closely 
  related.
