  This 
  species 
  is 
  distinguished 
  from 
  imperator 
  by 
  the 
  slenderer 
  form 
  of 
  

   head 
  and 
  body, 
  more 
  conspicuous 
  sinuses 
  and 
  pores 
  on 
  head, 
  larger 
  

   eye 
  and 
  correspondingly 
  narrower 
  interorbital, 
  less 
  deeply 
  bifid 
  

   ventrals, 
  longer 
  pectorals 
  and 
  fewer 
  rays
