  Type. 
  Head 
  and 
  abdominal 
  region, 
  wanting 
  fins 
  ; 
  British 
  Museum. 
  

  

  A 
  very 
  small 
  species, 
  apparently 
  not 
  exceeding 
  0-065 
  in 
  length. 
  

   Head 
  with 
  opercular 
  apparatus 
  occupying 
  one-quarter 
  of 
  the 
  total 
  

   length 
  of 
  the 
  fish 
  ; 
  maximum 
  depth 
  of 
  the 
  trunk 
  also 
  equalling 
  

   one-quarter 
  of 
  the 
  total 
  length, 
  and 
  the 
  caudal 
  pedicle 
  robust. 
  

   External 
  bones 
  coated 
  with 
  smooth 
  ganoine. 
  Dorsal 
  fin 
  opposed 
  

   to 
  the 
  pelvic 
  pair, 
  which 
  is 
  situated 
  at 
  the 
  middle 
  point 
  of 
  the 
  

   trunk. 
  Scales 
  large 
  and 
  smooth, 
  the 
  hinder 
  margin 
  slightly 
  

   convex, 
  scarcely 
  serrated, 
  but 
  sometimes 
  provided 
  with 
  from 
  one 
  

   to 
  four 
  slender 
  acuminate 
  denticles 
  ; 
  course 
  of 
  lateral 
  line 
  very 
  

   conspicuous 
  ; 
  four 
  longitudinal 
  series 
  of 
  flank- 
  scales 
  much 
  deeper 
  

   than 
  broad. 
  

  

  In 
  the 
  original 
  definition 
  of 
  this 
  species, 
  Egerton 
  seems 
  to 
  have 
  

   been 
  misled 
  by 
  the 
  distortion 
  of 
  the 
  type 
  specimen, 
  and 
  thus 
  

   supposed 
  the 
  relative 
  size 
  of 
  the 
  head 
  and 
  depth 
  of 
  the 
  trunk 
  

   of 
  the 
  fish 
  to 
  be 
  much 
  greater 
  than 
  now 
  proves 
  to 
  be 
  the 
  case. 
  

   Erom 
  an 
  examination 
  of 
  all 
  the 
  known 
  specimens, 
  the 
  present 
  

   writer 
  is 
  convinced 
  that 
  the 
  above 
  amended 
  definition 
  is 
  a 
  correct 
  

   expression 
  of 
  the 
  facts.
