158 DEEP SEA FISHES. 
together, little behind the humeral symphysis, with a single ray. The dis- 
tance from snout to vent is more than one third of the total length. Scales 
very small, deciduous, entirely covering body and head. Pyloric cca eight 
or nine. Lateral line distinct on the anterior half of the length. The pre- 
opercular spines, or angles, are less prominent and weaker in the young. 
Posterior nostril close to the eye; anterior on a slightly tumid prominence at 
each side of the snout halfway from the posterior to the end and about the 
same distance from the lip. 
Described specimen eight and three fourths inches in length. 
Dark brown; gill membranes, linings of mouth, branchial chamber and 
belly, and fins black.

Body narrow, tapering regularly, nape high ; depth equal length of head 
or two elevenths of the total length. Head moderately compressed, prom- 
inently convex from mouth to interocular space, and rather less so to and 
on the occiput, about five and one half times in the total. Snout short, four 
fifths as long as the eye, rounded, blunt, high in the internarial region, 
covered by scales. Mouth large, cleft descending backward in a wide 
curve to a vertical from the hind border of the eye; maxillary reaching two 
thirds of a diameter of the eye farther back, much widened at the posterior 
extremity, wholly separated from the mouth cleft by the intermaxillaries ; 
intermaxillary not extending farther backward than the hinder edge of the 
eye. Teeth small, closely set in wide villiform bands on intermaxillaries, 
mandibles, and palatines, in bunches on the basibranchials, and in a short, 
crescent-shaped band on the vomer. Eye nearly one fourth as long as the 
head, one and one fourth times in the snout, which in turn is three fifths of 
che interorbital space. A slender spine on the opercle above the base of the 
pectoral. Two short, compressed, rather blunt preopercular spines. Skin 
of head thin, covered with small scales, plainly showing the large mucous 
chambers in the skull beneath it. Pseudobranchiz very small. Gill
