Head and body rather elongate, compressed. Eye situated 

 high up, very small ; its major diameter is a little more than 

 ^ the length of the snout, which is about ^ the length of the 

 liead, which is not quite ^ the total without the caudal. 

 Mouth wide, its cleft very oblique, approaching the vertical, 

 with the lower jaw projecting in repose ; the maxilla, which 

 is widely dilated behind, measures more than half the length 

 of the head ; the premaxilla is a stout bone, firmly attached 

 to the maxilla, which it equals in length. Acute villiform 

 teeth, in rather broad bands uncovered by the lips in the pre- 

 maxillse and mandible, in narrow bands in the palatines, and 

 in a small patch on each side of the head of the vomer ; no 

 teeth on the tongue. 



Gill- openings very wide ; gill-covers complete ; long close- 

 set gill-rakers on the first arch. Pseudobranchiae rudimen- 

 tary, consisting of three or four small lamellae on each side. 



The dorsal fin begins above the origin of the ventrals ; the 

 whole fin is included in the anterior half of the body 

 measured with the caudal. Adipose dorsal rather large, 

 fimbriated. The anal fin begins a little more than a snout- 

 length behind the posterior limit of the dorsal. Caudal 

 forked. Pectorals entire, about as long as the maxilla, and 

 reaching just beyond the origin of the ventrals ; they arise close 

 to the ventral profile. 



Eight large pyloric ceeca. No air-bladder. 



Colours in the fresh state apparently uniform black 

 throughout.
