BOTHROCAROPSIS ALALONGA. WAT 
so far as may be determined in comparisons of specimens with more or less 
incomplete descriptions. All of the specimens in the collection are of deep 
sea species; ‘they are of uniform darkish to deep black and bear nothing in 
the way of markings to serve as hints to derivation or relationship. Pos- 
sibly such traces occur on younger individuals as is so frequently the case 
with other fishes, 
Of the nine localities from which specimens of the Lycodoids were taken 
five are recorded as being on soft mud, one as being on the ooze, two as be- 
ing from sandy and one as being from rocky bottoms. Aside from the fact 
that two thirds of them were caught on the soft bottom the obsolescence of 
the ventral fins is sufficient evidence of habits similar to those of the Disco- 
boles, or the Eels. 
ZOARCID As. 
Bornrocaropsis sub-gen. n. 
Form slender, elongate, compressed, covered with small circular scales ; 
similar in shape to the typical Lycodes. Eyes large. Vertical fins continu- 
ous. No ventrals. Body cavity short. Pectorals narrow, of thirteen rays. 
Small conical teeth on jaws, vomer, and the palatines. Lower jaw shorter, 
included by the upper. Bones of the skull with large cavities for the 
canals of the Lateral System. No barbel. Six branchiostegals; gill open- 
ings wide; gill membranes united, narrowly attached to the isthmus. 
Pseudobranchie present. 
Though it has a larger pectoral it may be that Maynea pusilla Bean 
belongs to this subgenus. Evidently Bean was right in separating the 
type of Bothrocara, 6. pusilla from his Maynea brunnea.

Br. r. 6; D.-98-102; A. 85-86; V.0; P. 13. 
Lycodiform, compressed, tapering and slender posteriorly ; depth one 
ninth of the total length, or one and six sevenths times in the head. Head 
large, long, one fifth of the total, as wide as high at the eyes, deeper than 
wide across the back, broad and slightly convex on the occiput; interorbital 
space narrow, convex. Snout large, its length one and one half to one 
and two thirds times that of the eye, broad, swollen above the jaws, prom-
