Head 5^ in total length; depth 6^; eye 2f in head; snout 5. D. II, 

 8 — about 125; V. 8. Body somewhat compressed; scales small, decid- 

 uous, about 25 vows in an obli([ue line from the vent to the dorsal fin, 

 24 from the upper angle of operculum to the vertical through origin of 

 the anal; interorbital area nearly flat, its width 4 in head; postor- 

 bital part of head somewhat longer than diameter of eye; snout broad, 

 obtuse; nostrils close to eye, the posterior nearly twice as large as 

 anterior one; maxillary extending to vertical through posterior margin 

 of orbit, its length equal to that of head without its postorbital portion; 

 length of mandible 3 times that of snout: intermaxillaries and mandible 

 provided with narrow bands of villiform teeth, those of the mandible much 

 shorter. A minute barbel, about \ as long as snout. Vomer and palate 

 toothless. Gill rakers lanceolate, elongate, 7 + 26, the longest 7 in head; 

 pseudobranchi:e absent; distance of first dorsal from snout nearly 5 times 

 in total length, second or longest ray in the typical specimen twice 

 length of snout; second dorsal almost continuous with the first, its 

 anterior rays the longest, about 4 times in length of head; anal inserted 

 under fourteenth ray of second dorsal, its rays all very short; in a dis- 

 tance equal to length of head, counting back from insertion, there are 33 

 rays; pectoral inserted under first branched ray of first dorsal, its length 

 in the most nearly perfect specimens equaling length of head without 

 snout; ventral origin very slightly behind origin of pectoral under third 

 branched ray of dorsal, reaching nearly to vent when laid back, its length 

 equaling 3 times that of the snout. Branchiostegals 7. Color yellowish 

 gray, lighter below. (Goode & Bean.) In deep waters of the Gulf of 

 Mexico oft' the United States coast, in 321 to 347 fathoms. {nanp6<i, large;

Head about 5| in total length ; depth 7i ; eye 4 in head ; snout 4. D. II, 

 8 or 9 — about 140; P. 13; V. 8; scales about 142. Body more compressed 

 than in B. viacrops ; scales small, cycloid, deciduous, about 25 rows from 

 the vent upward and forward to the dorsal fin, interorbital area flattened, 

 its greatest width 3f times in total length of head; postorbital portion of 

 head twice as long as eye; snout and nostrils normal; maxillary reaching 

 somewhat beyond posterior margin of orbit, its length twice in distance 

 from snout to origin of first dorsal; length of mandible 2k times in snout; 

 barbel slender, long, its length equal to li times orbital diameter. Teeth 

 in narrow villiform bands in each jaw, none on vomer or palatine Ijones; 

 gill rakers very long and slender, numerous, 17 + 35, the longest nearly 6 

 in head; pseudobraucbiie absent; first dorsal of 2 stout spines, the first 

 minute, the second elongate, ^nd 8 or 9 branched rays, its distance from 

 snout 5^ in total; second or longest simple ray nearly 8 times length of
