  The 
  description 
  in 
  the 
  synopsis 
  

   (p.

  of 
  P. 
  ophryas, 
  belongs 
  here. 
  From 
  P. 
  lethostigrna, 
  it 
  is 
  especially 
  distinguished 
  

   by 
  the 
  more 
  numerous 
  (5 
  + 
  14) 
  gill-rakers, 
  and 
  by 
  the 
  much 
  more 
  spotted 
  coloration. 
  

   The 
  interorbital 
  space 
  is 
  also 
  narrower 
  in 
  specimens 
  of 
  the 
  same 
  size.

  It 
  seems 
  more 
  natural 
  to 
  regard 
  Ancylopsetta

  genera 
  distinct 
  from

   The 
  genus 
  Notosema 
  is 
  distinguished 
  from 
  Paralichthys' 
  " 
  on 
  account 
  of 
  its

  ventral 
  fin, 
  the 
  triangular 
  elongation 
  of 
  the 
  anterior 
  rays 
  of 
  the 
  dorsal

  the 
  

   highly 
  ctenoid 
  character 
  of 
  the 
  scales 
  on

  colored 
  side 
  of

  These 
  char- 
  

   acters 
  are 
  all, 
  however, 
  of 
  degree 
  only,
