  This 
  species 
  is 
  best 
  recognized 
  by 
  the 
  presence

   band 
  from 
  snout 
  along 
  middorsal 
  line 
  of 
  head, 
  thence 
  posteriorly 
  

   along 
  each 
  side 
  of 
  base 
  of 
  dorsal 
  fin, 
  and 
  ending 
  on 
  dorsal 
  side 
  of 
  caudal 
  

   peduncle; 
  no 
  white 
  bars 
  are 
  present.
