lary teeth biserial, the inner teeth enlarged. Cephalic appendage reaching 

 nearly to base of first dorsal, its length 4| in total. Distance of dorsal 

 from snout 2\ in total, that of the anal the same; the dorsal and anal 

 fins received in a groove formed by the. scales along their bases; ante- 

 rior portion of second dorsal and second anal less elevated than in B. 

 macclellandii. The difterentiations between the developed and nndevel- 

 oped rays of the anal are so .slight that the limits of the so-called anterior 

 and posterior sections of the fin can not be determined. Length of the 

 longest anal ray about 2 in body length. Specimens were obtained by the 

 Blake at the following stations: XCIX, off (iranada, 90 fathoms; CXIII, 

 off Neris, 305 fathoms; CLXXXV, Lat. 25^ 33' N., Long. 84*^ 21' W., 101 

 fathoms. (Goode & Bean.) This species seems doubtfully distinct from 

 B. macclellandii. (atlanticus, of the Atlantic.)

Suborder ANAOANTHINI. 

 (The Jugular Fishes.) 



Vertical fins very long, destitute of true sjiines ; tail isocercal, the pos- 

 terior vertebra' progressively smaller; ventr.-ils jugular, without spines; 

 hypercoracoid without perforation or foramen; no pseudobranchia?. The 

 osteological characters of this group, called by him Gadoidea, are thus 

 given by Dr. Gill: 



" Jugulares Avith the orbito-rostral portion of the cranium longer than 

 the posterior portion, the cranial cavity widely open in front; the supra- 

 occipital well developed, horizontal and cariniform behind, with the 

 exoccipitals contracted forward and overhung by the supraoccipital, 

 the exoccipital condyles distant and feebly developed, with the hyper- 

 coracoid entire, the hypocoracoid with its inferior process convergent 

 toward the proscapula, and the fenestra between the hypercoracoid and 

 hypocoracoid." (Gill, Proc. Ac. Nat. Sci. Phila. 1884, 170.) 



A large and important group, chiefly confined to the cold depths of the 

 ocean and the northern seas. From all other typical fishes they are sep- 

 arated by the entire hypercoracoid. (d^- privative, without; dxavba, 

 spine.) 



a. Caudal fin pre.sent; tail not greatly elongate; hody tapering or coniform behind, 

 with many procurrent caudal rays above and below; suborbitals moderate. 

 b. Frontal bones paired, with a triangular excavated area above, the divergent 

 front.al crests continuous from the forked occipital crest ; ribs wide, approxi- 

 mated, channeled below or with inflected sides; no barbels. 



Merluccud.e, ccxni. 

 bh. Frontal bones normal, not forming a triangular excavated area above; ribs 

 normal; chin with a barbel (rarely obsolete). Gadid^e, ccxiv. 



aa. Caudal fin wanting; tail very long, tapering behind; suborbitals very bro.ad.
