  It

  an 
  ally 
  of 
  

   Congrogadus.

  The

  the

  Otophidium 
  Gill, 
  gen. 
  nov. 
  

   Type 
  Genypterus 
  omostigma 
  Jordan 
  & 
  Gilbert. 
  This 
  genus 
  differs 
  from 
  Ophidium 
  in 
  

   the 
  presence 
  of 
  a 
  sharp 
  concealed 
  spine 
  on 
  the 
  opercle. 
  The 
  typical 
  species 
  has 
  been 
  

   wrongly 
  referred 
  to 
  Genypterus.

  The 
  Brotuline 
  genera 
  (Bythites 
  and 
  Dinematichthys) 
  have 
  been 
  erroneously 
  placed 
  

   in 
  the 
  Synoposis 
  among 
  the 
  Gadidw. 
  For 
  the 
  characters 
  of 
  the 
  Brotulidw 
  see 
  Gill, 
  

   Proc. 
  Ac. 
  Nat. 
  Sci. 
  Phila., 
  1863, 
  252; 
  1864, 
  200, 
  and 
  1884, 
  169, 
  175. 
  These 
  fishes 
  are 
  

   certainly 
  much 
  nearer 
  the 
  Ophidiidw, 
  or 
  even 
  the 
  Lycadidat, 
  than 
  the 
  Gadidas.
