  A 
  large 
  species, 
  attaining 
  a 
  length 
  of 
  about 
  0*3. 
  Length 
  of 
  head 
  

   with 
  opercular 
  apparatus 
  somewhat 
  exceeding 
  the 
  maximum 
  depth 
  

   of 
  the 
  trunk, 
  which 
  equals 
  about 
  one-fifth 
  of 
  the 
  total 
  length 
  of 
  the 
  

   fish. 
  The 
  rugose 
  ornament 
  of 
  the 
  head 
  and 
  opercular 
  bones 
  very 
  

   fine, 
  but 
  conspicuous 
  ; 
  maxilla 
  and 
  dentary 
  longitudinally 
  striated. 
  

   Pelvic 
  fins 
  arising 
  slightly 
  in 
  advance 
  of 
  the 
  middle 
  point 
  of 
  the 
  

   trunk, 
  with 
  the 
  dorsal 
  fin 
  directly 
  opposed. 
  Scales 
  large 
  and 
  nearly 
  

   smooth, 
  but 
  with 
  a 
  faint, 
  coarse 
  rugosity, 
  most 
  conspicuous 
  in 
  the 
  

   caudal 
  region 
  ; 
  their 
  hinder 
  margin 
  is 
  very 
  slightly 
  convex 
  and 
  not 
  

   serrated 
  ; 
  at 
  least 
  six 
  longitudinal 
  flank-series 
  much 
  deeper 
  than 
  

   broad.

  preserved 
  fish 
  about 
  0'24

  with 
  the 
  

   head-bones 
  scattered;

  The 
  conspicuous 
  rugose 
  ornament 
  of 
  the 
  cranial 
  

   roof 
  and 
  the 
  radiating 
  folds 
  on 
  the 
  angle 
  of 
  the 
  pre- 
  

   operculum 
  are 
  shown

   well 
  exhibited.
