202 DEEP SEA FISHES. 
operculum, forward of the bases of the pectorals, first ray with a filament, 
reaching the anal. Vent close to the first ray of the anal, farther back than 
the head by nearly the length of the orbit. Scales medium, spinose, with 
close set, small, sharp, declined spinules arranged in eight or more Jongitu- 
dinal series, hindmost prickles larger extending beyond the edge of the 
scale. The scales of the head and snout are smaller and harsher to the 
touch. The width of the scaly area between the nostrils is equal the width 
of the snout at the lateral angles. Each angle of the snout is surmounted 
by a rosette of small spines. Between the lateral line and the base of the 
first dorsal there are seven rows of scales. Six pyloric appendages. 
Brownish gray, with silvery tint where scales are lost, or silvery gray 
changing to brownish by brown puncticulations ; dorsal darker; linings of 
body cavity and mouth black. Described specimen eight and one fourth 
inches in length.

In shape this species is similar to J/. leucopheus ; its most patent distin- 
guishing features are a narrower snout, a narrower interorbital space and 
the backward positions of the ventrals. Body compressed, tapering to a 
slender thread in the caudal section. Head one fifth of the total length, 
somewhat compressed, width less than the depth and more than half the 
length. Outline from snout to first dorsal convex above the nostrils and 
again at the nape. Snout short, not as long as the orbit, less than twice 
the interorbital space, distance of tip from mavxillaries about equal the dis- 
tance between the orbits which is two thirds of the width across the lateral 
angles at the end. The angles in front of the nostrils are not much pro- 
nounced, apices with groups of small spines. Mouth of moderate size, 
maxillary extending below half of the orbit. Teeth small, in villiform bands, 
subequal, larger in the outer row near the symphysis. Eye large, longer 
than the snout, two sevenths of the head, length of orbits twice their distance 
apart. Barbel small, one third as long as the eye. Suborbital ridge low, 
rounded, scarcely prominent below the hind part of the eye. Dorsal origin 
above the middle of the pectoral; second spine of medium size, serrate, 
robably ending in a filament; base descending steeply backward. Second
