Height 7 or somewhat more, head 4'/,—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 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. Brownish, back blackish.
