Height 7 or somewhat more, head ^. l / 2 5, eye 8 10, 

 nearly half as long as snout and as interorbital space. Front 

 slightly concave, laterally with 3 low, blunt tubercles. Lower 

 jaw prominent with a sharp point at the symphysis, directed 

 downward. Origin of dorsal and anal opposed, slightly behind 

 the middle of length. Ventrals somewhat before that middle, 

 nearer to anal than to pectorals, not reaching the anal. Pec- 

 torals narrow, reaching to origin of ventrals or not so far. 

 Anus in the middle of the length and in the middle between 

 ventrals and anal. 6 10 vertical, nearly equally large teeth 

 in the intermaxillary. In the anterior third of the maxillary 

 about 30 35 nearly vertical, small teeth, which increase 

 very slightly in size from before backward; behind them 

 stronger teeth, inclined forward, the number of which gains 

 with age to about 20 or more, gradually becoming larger 

 backward. In the anterior part of the mandibula about 15 

 equally small teeth, behind the third a large vertical fang, a 

 second at the end of the series, behind it a series of about 

 70 teeth, all vertically placed and gradually increasing in size 

 from before backward. Vomer with a series of 4 5 curved 

 teeth, the last of which is the largest; 4 6 on the palatines, 

 6 8 on the pterygoids. Luminous organs small: a black 

 suborbital, two operculars above each other, the dorsal on the 

 level of the eye, the ventral on the level of the pectorals. 

 10 between branchiostegal rays, 13 14 in a ventral series 

 between isthmus and ventrals, 4 between ventrals and anal, 

 the 2 anterior of which before the anus; 14 16 between 

 origin of anal land caudal. About 4 behind anal. 9 10 in a 

 lateral series between operculum and the vertical through anus, 

 one or two hindermost distant from the others. A luminous 

 supracaudal patch strongly developed. Brownish, back blackish.
