  about 
  0-115

  part 
  of 
  the

  The 
  maxilla

  not 
  much 
  arched, 
  while 
  both 
  

   this, 
  the 
  facial 
  and 
  opercular 
  bones 
  are 
  nearly 
  smooth. 
  

   The 
  anterior 
  pelvic 
  fin-rays 
  are 
  broad 
  and 
  flattened, 
  

   with 
  a 
  fringe 
  of 
  conspicuous 
  fulcra 
  (shown

  About 
  five 
  rows 
  

   of

  some 
  of 
  

   those 
  at 
  the 
  beginning 
  of 
  the 
  caudal

  In 
  the 
  

   hinder 
  half 
  of 
  the 
  caudal 
  region 
  the 
  lateral 
  line 
  forms 
  

   a 
  very 
  prominent 
  ridge. 
  The 
  enlarged 
  scale 
  at 
  the 
  base 
  

   of 
  the 
  upper 
  caudal 
  lobe 
  is 
  pointed 
  in

  obtuse 
  behind, 
  

   and 
  finely 
  ornamented 
  with 
  striae 
  of 
  ganoine 
  radiating 
  

   from 
  the 
  longitudinal 
  middle 
  line.
