  A 
  small 
  stout 
  species 
  attaining 
  a 
  length 
  of 
  about 
  0'05. 
  Length 
  

   of 
  head 
  with 
  opercular 
  apparatus 
  slightly 
  less 
  than 
  the 
  maximum 
  

   depth 
  of 
  the 
  trunk 
  and 
  contained 
  scarcely 
  more 
  than 
  four 
  times 
  in 
  

   the 
  total 
  length 
  of 
  the 
  fish 
  ; 
  width 
  of 
  the 
  caudal 
  pedicle 
  not 
  

   exceeding 
  one-third 
  of 
  the 
  maximum 
  depth 
  of 
  the 
  abdominal 
  region. 
  

   Vertebrae 
  less 
  than 
  40 
  in 
  number. 
  Pelvic 
  fins 
  arising 
  opposite 
  the 
  

   origin 
  of 
  the 
  dorsal, 
  which 
  has 
  14 
  rays 
  ; 
  anal 
  fin 
  with 
  about 
  

   12 
  rays, 
  very 
  slightly 
  nearer 
  to 
  the 
  caudal 
  than 
  to 
  the 
  pelvic 
  fins.

   the
