HOrilROCAROPSIS ALALOXGA. 127 



SO fiir as may be detennined in comparisons of specimens with more or less 

 inconijilete 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 frtHjucHtly 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 tiie ooze, two as be- 

 ing from sandy and one as being from rock}' 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.E. 



BoTHROCAKOPSis sub gen. n. 



Form slender, elongate, compressed, covered Avith small circular scales ; 

 similar in shape to the typical Lycodes. E\-es large. Vertical fins continu- 

 ous. No ventrals. Body cavit}' 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. 

 Pseudobranchia3 present. 



Though it has a larger pectoral it may be that JIai/uca piisilld Bean 

 belongs to this subgenus. Evidently Bean was right in separating the 

 type of Bothrocara, B. pusilla from his Maynea hnumca.

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-
