  The 
  general 
  color 
  is 
  brown, 
  with 
  cross 
  reticnlations 
  of 
  black. 
  Sides 
  

   of 
  head 
  and 
  body 
  along 
  base 
  of 
  anal, 
  orange 
  ; 
  anal, 
  caudal, 
  and 
  pectorals 
  

   light, 
  with 
  dusky 
  shadings 
  5 
  dorsal 
  finely 
  mottled 
  with 
  bhick 
  and 
  bear- 
  

   ing 
  six 
  black 
  spots 
  on 
  areas 
  of 
  white, 
  the 
  first 
  of 
  these 
  spots 
  being 
  on 
  

   the 
  sixth 
  ray 
  and 
  the 
  last 
  on 
  tlie 
  next 
  to 
  last 
  spine; 
  a 
  black 
  bar 
  from 
  

   front 
  of 
  eye 
  downward, 
  and 
  another 
  from 
  posterior 
  margin 
  obli(piely 
  

   down 
  and 
  backward. 
  

  

  This 
  species 
  differs 
  from 
  the 
  typical 
  form 
  in 
  its 
  greater 
  compression 
  

   of 
  the 
  body 
  and 
  its 
  increased 
  number 
  of 
  dorsal 
  spines. 
  It 
  seems 
  to 
  

   represent 
  the 
  form 
  described 
  by 
  lioulenger 
  as 
  Blenniojyhidium, 
  which 
  

   genus 
  we 
  can 
  not 
  separate 
  from 
  Opisthocentrus.
