196 DEEP SEA FISHES. 
down and backward as a much rounded lobe making the hind margin deeply 
concave above it. 
First dorsal originating above the bases of the pectorals; first spme 
small, weak ; second slender, with small spinules at a moderate distance from 
one another, with a filamentary extremity; base as long as the eye, de- 
scending gradually backward. Second dorsal low, scarcely visible forward, 
separated from the first dorsal by one length of the base of the latter. 
Anal well developed, origin below the middle of the space between the 
dorsals. Ventrals small, first ray with a hair-like filament which reaches 
back upon the anal fin, origin little farther backward than that of the pec- 
torals. Vent close to the origin of the anal, distant from the head Jess than 
two fifths of the latter's length. Scales small, harsh with sharp spines in 
keel-like series, those in the median series larger. Six scales in a row from 
the lateral line to the base of the first dorsal. 
Black, shading to purple over the muscular portions of the body; linings 
of mouth and body black.

Head and body massive ; caudal section elongate, compressed ; greatest 
depth equal to five sixths of the length of the head. Length of the head 
about two thirds of the distance from the snout to the anal fin. Bones of 
the skull firm. Snout large, longer than the orbit, lateral angles moderate 
and separated by a distance equal to the orbital length. On the skull the 
rostral ridges are strong, the median being highest and extended back to 
the interorbital region where it becomes lower and continues to the hinder 
portion of the space. There is a ridge backward from each eye on the 
crown; the skull rises in a bony edge above the orbits; and across the 
angles between the nostrils and the eye the distance is greater than that 
between the lateral angles at the end of the snout. Eye large, equal in 
length to the interorbital width, one and one half times the distance from
