PARALIPARIS ANGUSTIFRONS. 119 
skull is rather concave between the orbits because of the greater height 
of the bones around them. Epicoracoid long, slender, spine-like, more 
than half as long as the head, extending down and back in the flank so 
much that its lower end is nearly one length of the orbit behind the 
base of the pectoral. 
Pectoral of about twenty-four rays divided by an interspace, containing 
three shorter and widely set rays, into a lower group of four and an upper 
group of seventeen rays. Apparently without a ventral disk, but with 
a rudimentary pelvis, Plate XXIX., fig. 2,in which the elements are less 
developed than in either P. fimbriatus or P. latifrons. Vertical fins confluent. 
First ray of the dorsal a very short distance backward of the base of the 
pectoral, near a vertical from the end of the opercle or the vent. Caudal 
narrow, acuminate. Anal origin eight or nine rays farther backward than 
that of the dorsal. 
Uniform black, or lightening to brown in the posterior half; linings of 
the body cavity black. 
Total length three inches or more.

Body compressed, narrow, depth two elevenths of the tota: length, retain- 
ing depth to the mid length then tapering rapidly. Head narrow, short, six 
and one half times in the total length, nearly twice as high as wide ; crown 
convex. Snout short, blunt, rounded, not as long as the orbit. Orbital 
length half of the interorbital width, more than one fourth of the length of 
the head. Mouth wide; cleft rising forward on a gradual incline ; maxillary 
extending farther back than the orbit. Teeth subconical, hooked, small, in 
villiform bands of moderate width, series more numerous than in P. datifrons. 
At the base the teeth are abruptly broadened. Hind angle of operculum 
spine-like, elongate, directed downward. Epicoracoid moderately long 
and slender. 
Vertical fins confluent; dorsal origin on the nape; anal origin about 
ten rays farther backward than that of the dorsal; both well developed ;
