- 302 REPORT OF NEW JERSEY STATE MUSEUM. 
upper a trifle convex in its inclination while lower is almost 
straight to caudal peduncle. Edges of body slightly trenchant. 
Caudal peduncle compressed, slender, and its least depth about 
half its length. Head moderate, well compressed, deep, and 
upper profile evenly convex from tip of snout to occiput, after 
which it is straight to origin of rayed dorsal. Lower profile of 
head slightly concave to ventral process close in front of base 
of ventral. Snout short, long as broad and with convex sur- 
face. Eye large, a trifle longer than deep, nearly midway in 
depth of head, and a little anterior. Pupil a little longer than 
deep. Mouth well inclined, moderate, curved a little in gape, 
and mandible protruding a little. Maxillary narrow, well in- 
clined, and reaching front margin of iris, distal expansion about 
24 of horizontal diameter of pupil. Lips rather thin. Teeth 
moderately small, conic and in rather narrow bands in jaws. 
Small teeth in bands on vomer and palatines. Tongue rather 
thick, flattened above, slightly minutely asperous in middle, and 
free in front. Nostrils near together, close in front of eye on 
side of snout, anterior simple, and posterior a deep slit vertically. 
Interorbital space broadly convex, becoming trenchant gradually. 
behind. Preorbital 1% in eye horizontally. Gill-opening extend- 
ing forward to front margin of eye. Gill-rakers 5 + 15, lanceo- 
late, and half of eye horizontally. Filaments about */, of latter. 
Isthmus narrow and slightly rounded. Body apparently naked, 
or with traces of minute imbedded scales on posterior portion of 
trunk, about caudal peduncle and base of caudal. Lateral 
line conspicuous, complete, strongly convex for first half of its 
course, and posterior or straight portion with obsolete or in- 
distinct scutes or bony scales forming a narrow keel along 
side of caudal peduncle. Spinous dorsal low, its origin fall- 
ing about posterior margin of gill-opening in vertical, spines 
slender, short and second longest, others graduated more or 
less down. Rayed dorsal with its origin falling well before 
that of rayed anal or about opposite that of spinous anal, 
and with first 7 rays elongated into slender thread-like filaments, 
of which first, which is longest, is as long again as entire length 
of fish. Other filaments graduated down to last which is shortest, 
though second but little shorter than first. Posterior non-fila-
