Head6; depth 10; eye 5| in l*3ad; body much compressed, elongate, 

 tapering to a very slender tail ; head long, moderately compressed, sub- 

 conical, the profile gradually ascending in nearly a straight line from tip 

 of snout to origin of dorsal; interorbital space slightly convex, spiny, its 

 width 4f times in length of head, and slightly greater than diameter of 

 eye; opercles and head generally covered with numerous and strong 

 spines, as described in the generic diagnosis; mouth very large and wide; 

 maxillary extending far behind eye and much expanded at its tip, its 

 length more than | that of head; length of mandible equal to greatest 

 height of body; jaws, voiner, and palatines with narrow bands of villi- 

 forrn teeth, none of which is enlarged; gill rakers 15 on anterior arch 

 below the angle, 3 rudimentary ones above. Anterior pair of nostrils 

 nearly on top of snout and somewhat nearer its tip than to eye, separated 

 by a narrow space and placed immediately in front of middle of eye; 

 behind each posterior nostril a strong spine projecting outward and 

 upward ; pores of the head arranged much as in Bassozetus ; scales minute ; 

 lateral line not to be clearly made out ; 3 rows of minute pores on each 

 side of dorsal, median, and ventral, beginning near head and extending 

 well toward extremity of tail. Dorsal origin slightly behind vertical 

 through pectoral base, its distance from snout nearly 6 times in length of 

 body, its rays moderately long, the longest about as long as snout, and 

 very numerous; anal origin in vertical from twenty-second or twenty- 

 third dorsal ray, its distance from snout 3^ times in length of body, its 

 rays about as long as those of dorsal ; pectoral imperfect, its length in the 

 type equaling that of head; ventrals a bifid filament, placed close to 

 the humeral symphysis, well in advance of pectoral, its length equal to 

 height of body; distance from origin of ventrals to vent nearly equal to 

 length of head ; ventral not reaching vent by a distance equal to length of 

 snout. Color blackish brown. The type (No. 35625, U. S. Nat. Mus. ) is 153 

 mm. in length, from Albatross Station 2230, lat. 38 27' N., long. 73 02' W.,

Body stout in front, tapering behind; tail not greatly exceeding the 

 length of the rest of the fish; head scaly, thick, its top surface flat, with 

 depressed and moderately projecting snout; a pair of minute postnasal 

 spines; a strong and much curved spine on the operculurn; several weak 

 spines on the angle of the preoperculum, and several at the posterior 

 angle of the suboperculum ; mouth moderately large, the lower jaw 

 included; several narrow slit-like pores along the margin of the pre- 

 orbital and suborbital; 2 minute pores on under surface of mandible 

 near its symphysis, and not far behind them 2 long slit-like pores; the
