much the appearance of Lycenchelys paxillus, the cheeks tumid, much pro- 

 jecting laterally, the greatest width of head more than ^ its length. 

 Snout short and broad, much depressed, the head scarcely constricted 

 opposite orbits. Eyes with little lateral range. In the single type speci- 

 men the upper jaw greatly overlaps the lower, the mandibular band of 

 teeth shutting entirely within those on premaxillaries. Teeth in upper 

 jaw ill a single series, 2 or 3 small teeth sometimes present anteriorly, 

 giving traces of an inner series. In lower jaw the teeth are sparsely set 

 in a l)road band anteriorly, becoming suddenly contracted to a single series 

 on middle of sides. None of the anterior mandibular teeth enlarged, 2 or 

 3 of posterior teeth on sides larger and hooked backward. No teeth on 

 vomer or palatiues. Nostril in a short tube. Gill slits wide, reaching to 

 below pectorals, but not extending farther forward below than above. 

 Width of isthmus ^ length of slit. A series of 7 pores along mandible 

 and preopercle; a second series of 7 or 8 extending from snout along sides 

 of head above premaxillaries. Lateral line faint, descending, its position 

 veutial. Dorsal inserted over middle of pectorals, its origin as far from 

 occiput as is the latter from front of pupil; distance of front of anal 

 from snout equals i length of body ; ventrals short, less than length of 

 pupil; pectorals with posterior margin obliquely truncate, the upper 

 rays longest, the lower growing regularly shorter, thickened at tips, the 

 rays 15 or 16, the longest 2^ in head. Scales small, embedded, cover- 

 ing 1)ody and most of vertical tins. A few very small, scattered scales 

 on nape, posterior part of occiput, and contiguous parts of cheeks 

 and opercles. Lateral line single, indistinct, running obli(iuely downward 

 to near base of anal, thence backward, not reaching base of caudal fin. 

 Color dark brown, black on opercles, sides of snout, tins, and lower parts 

 generally ; a broad light bar across head behind eyes, extending down on 

 cheeks; some light mottling on mandible and gular membrane; lower 

 rays of pectorals margined with whitish; lining of mouth, gill cavity, 

 and peritoneum jet black. North Pacific. Two specimens known; the 

 type above described from Santa Barbara Islands, the second from Albatross 

 Station 3210, south of Saanak Islands, Alaska, depth 483 fathoms. 



On this Dr. Gilbert has the following notes: 



"The stomach contained remains of Crustacea. Colors in life, head and 

 body light brown, the lower parts darker; snout, suborbital r(>giou, and 

 a ban<l across pectorals greenish gilt; no light bar on head. Depth 12f in 

 length; head 5*; maxillary 2^ in head; eye 7, equal to interorbital width. 

 Widtli of bone l>etween orbits 17 in head. Snout 3i in head. Teeth above 

 in a narrow band, reaching only about halfway of gape. In the mandi- 

 ble, teeth are absent on posterior f of gape. The gill slit extends a little 

 farther forward below than above. Ventrals as long as pupil. Longest 

 pectoral ray 2f in head. Head wholly scaled behind eyes. Lateral line 

 not evident."
