The teeth are in two bands in each jaw, the outer band being enlarged : the 

 vomerine teeth also are enlarged.

 the snout. 



The colour is grey : the vertical fins in their posterior third or fourth have 

 a very narrow black edge.

 twice that of the eye. 



The mouth-cleft reaches to the posterior border of the pupil. 



The vomerine teeth are in a broad band of some length. 



The dorsal fin begins above the gill-opening. 



Colours dark brown, pectorals and vertical fins nearly black.

Congromurxna guttulata, Giinther, Challenger Deep-Sea Fishes, p. 252. 

 Congrellus guttulatus, Ogilby, loc. cit. supra. 



This species, if my identification be correct, differs from G. squaliceps, only 

 in the following particulars : — 



The head measured to the gill-opening is more than three eye-lengths shorter 

 than the distance between the gill-opening and the vent, which is not quite a 

 third the length of the tail. 



The snout, which is blunt-pointed, is a fourth the length of the head. 



The diameter of the eye is between half and two-thirds the length of the 

 snout. 



The mouth-cleft reaches to the posterior border of the pupil. 



The dorsal fin begins behind the root of the pectoral fin.
