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 ro—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, 
11 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. 
Habitat: Ceram Sea (1914 M.)!. — MHawaian Islands
