rARALIPARIS ANGUSTIFRONS. 119 



skull is rather concave between tlie orbits because of tlic 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 Hank 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 rudimentai'y pelvis, Plate XXIX., fig. 2, in which the elements are less 

 developed than in either P. JiiiihrUUiis or P. lafifrons. Vertical fins coulluent. 

 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 totai 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 

 villiforra bands of moderate width, series more numerous than in P. lafifrous. 

 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 ;
