198 DEEP SEA FISHES. 
short, four and three fifths times in the total, rounded on the sides and 
below, flattened on the crown, narrowed and pointed at the snout. Snout 
short, four fifths as long as the eye, narrowing forward, prominent, length 
from the teeth equal that from the eye, ending in a bunch of small spines; 
a small spinose angle at the junction of the supranarial with the suborbital 
ridges. Suborbital ridges low, not extended on the preopercle. Skull with 
a median ridve on the snout reaching backward to the interorbital space, 
and with two short, curved ridges between the hind portions of the eyes 
on the crown. Mouth medium, front edge below the anterior nostril, end 
of maxillary a trifle in front of the hinder edge of the orbit. Teeth small, 
subconical, in villiform bands, larger in the outer series of the upper jaws. 
Barbel slender, as long as the orbit. The prominent edge on the preopercle 
descends slightly backward and bears a shallow indentation above the 
rounded lower extremity. Eye prominent, large, longer than the snout, 
three and three fifths times in the length of the head, equal the interorbital 
width. Orbits rising above the space between them. Opercular membranes 
well developed, hinder angle of operculum turned up and backward and 
reaching below the second ray of the dorsal. Base of the first dorsal hardly 
as long as the eye, origin above the axil of the pectoral. Dorsal spine 
smooth, or with one or two small cusps near the base, about two thirds as 
long as the head, including the filamentary extremity. Second dorsal fin 
low, separated from the first by one and one half times the length of the 
base of the latter. Pectorals small, shorter than the first dorsal. Ventrals 
small, bases below the middle of the operculum, forward of the pectorals ; 
upper ray with a filamentary extremity, as long as the first dorsal ray. 
Gill membranes united, free from the isthmus; openings wide. Four 
gills, slits short, that behind the fourth gill very short; rakers absent from 
the front of the first arch, elsewhere rudimentary. 
Vent between the ventrals, nearer to their bases than to the origin of 
the anal, from which it is separated by the length of the snout. 
Seales without spinules, thin, deciduous, with very fine strize, absent from 
the suborbital section and the lower surface of the head. 
Length of the specimen described ten inches. 
Head black; linings of mouth and body cavity black ; muscular por- 
tions and fins brown to blackish.
