of praeoperculum. Dorsal opposite to anterior third of anal 

 which reaches far beyond vertical through adipose fin and 

 ends near forked caudal. The origin of dorsal opposite to 

 second or third ray of anal, the origin of which is slightly 

 behind middle of length. Origin of ventrals well before middle 

 of length. Anus shortly before anal. Some excessively thin 

 scales and wholly concealed beneath the skin are evident in 

 some places in connection with the luminous organs. Inter- 

 maxilla with about 2 3, maxilla with about 12 large curved 

 teeth, the interspaces between them filled by uniformly short 

 teeth. Mandible with about 10 12 large, curved teeth, with 

 smaller in the interspaces. Vomer with a pair of teeth hooked 

 backward, those on the palatines and pterygoids in a single 

 series, the 2 or 3 anterior enlarged, the posterior gradually 

 smaller. Luminous organs, a black suborbital, posteriorly con- 

 nected with a whitish oblong glandular patch. Two operculars, 

 a dorsal one on the level of eye, connected with a small 

 oblong glandular patch, an indistinct one behind edge of 

 maxillary, one on each side behind the symphysis, 9 between 

 the branchiostegal rays. In the ventral series 4 in advance of the 

 pectorals, the 2 opposite series strongly converging forward, 

 ii between pectorals and ventrals, 5 between ventrals and 

 anal, the anus situated between the fourth and fifth; 23 be- 

 tween origin of anal and caudal, the 4 hindermost behind 

 anal. Third organ of the anal series outside the series, above 

 the interspace between the second and fourth. 13 14 in the 

 lateral series between operculum and vertical through origin 

 of anal, the anterior one outside the series, far above the 

 pectorals, ventrally 2 glandular patches behind each other 

 above the anterior caudal rays; dorsally above them a similar 

 organ. Brownish black above, jet-black below. Vertical fins 

 with dark spots, usually arranged in cross lines. Length 

 over 190 mm.
