MERLUCCIUS ANGUSTIMANUS. 183 
physis, a stronger one at the hind ends of the lower jaws. Gills four, a slit 
behind the fourth; rakers more than half as long as the eye, slender, eight 
on the outer edge of the first arch on the upper segment and eighteen on 
the lower. Pseudobranchiz none. Vent below the origin of the dorsal fin, 
some distance forward of the end of the body chamber. 
Fins with slender rather soft and flexible rays. First dorsal short; third 
ray prolonged in a filament, longer than the head. Second dorsal united to 
the first by a low membrane, anterior rays as long as the eye, longest rays 
near the caudal, median rays shorter. Anal fin similar to second dorsal, but 
not so deep, and originating slightly forward of it. Caudal separate from 
the other fins, median rays longer. Pectorals slender, longer than the head. 
Ventrals narrow, of seven rays, two of the uppermost being very long, near 
twice the length of the head. Scales thin, deciduous, covering top and sides 
of head and chin, absent from a small rounded space in front of the vent 
backward of the ventrals. Lateral line about eight scales below the dorsal, 
curved anteriorly, indistinct backward. On the head the sense organs of 
this line are similar to those of Phyciculus rastrelliger, Plate LX XXII. fig. 2, 
but are larger and, in the mandibular series, one or two less in number. 
Brownish, probably reddish in life; purplish to black on the chin, belly 
and sides around the pectorals and up to the dorsal fin; bases of fins 
and hinder parts of caudal blackish. Linings of mouth, throat and belly 
blackish.

Moderately elongate and compressed; depth nearly one sixth of the 
total length; width three fourths of the depth; caudal pedicel slender. 
Head long, one third of the leneth to the base of the caudal, four fifths as 
wide as high, narrower toward the throat; crown broad, longitudinally 
straight, slightly arched transversely, interorbital space one and one third 
times as wide as the eye. Snout long, broader than deep, blunt at the end, 
one and one half te one and two thirds times as long as the orbit. Eye
