130 DEEP SEA FISHES. 
and slender posteriorly. The length of the body cavity is about twice the 
length of the head; the total length is ten times the depth. Head long, 
one sixth of the total, subquadrate in transsection behind the orbits, a trifle 
deeper than wide, slightly arched from snout to nape. Parietal region 
broad, flattened; skull with a low median keel, and a narrow interorbital 
space about two thirds as wide as the eye. Snout nearly twice the length 
of the eye, broadened above the jaws, somewhat prominent above the 
end. Mouth wide, horizontal; cleft extending little backward of a vertical 
from the anterior edge of the orbit; maxillary subtending half of the 
eye. Teeth small, conical, in villiform bands on jaws, vomer, and palatines, 
outer. series a little the larger. Eye medium, one half as long as the 
snout on the largest specimen and three fourths on the smallest. Oper- 
culum small, with a membranous flap and a flexible produced upper angle. 
Dorsal fin higher toward the middle of its length, originating above the 
axil of the pectoral. Anal origin below the nineteenth ray of the dorsal. 
Caudal not distinct from dorsal and anal, as long as the eye, sharp pointed. 
Pectorals moderately broad, half as long as the head, blunt pointed, ends 
of rays protruding as a fringe. Scales very small, absent from head and 
shoulders. Lateral line not apparent. Length nineteen and one half 
inches. 
The smallest specimen differs in certain respects from the foregoing. 
The head is two elevenths of the total length, the snout is about one and 
one half times as long as the eye, the maxillary does not reach to a ver- 
tical from the middle of the orbit, and the scales encroach on the bases 
of the fins only in the posterior third of the length, near the caudal. The 
decrease in depth in the hinder portion of the body is very regular to 
the slender extremity of the tail. Pectorals short, three fifths as long as 
the head, rounded and fringed on the hind border. Teeth conical, outer 
series of upper jaws much and of lower jaws but little larger. The differ- 
ences seen on these individuals are mainly such as would exist between 
young and old, viz., shorter snout, larger eye, longer head as compared 
with tail, and fewer scales on the bases of the fins. Length of smallest 
specimen twelve inches. 
Color dark brown or blackish, muscular portions lighter, fins darker.
