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. Pectorals 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 and 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. Dorsal spines (total): 0; Dorsal soft rays (total): 13 - 15; Anal spines: 0; Anal soft rays: 18 - 20; Vertebrae: 30 - 32.
