 dorsal to occiput slightly less than that from occiput to posterior nostril. Head and 

 trunk contained 3-^ in tail. Pectorals 2| in head. Dorsal about 100 ; anal about 85; 

 both counted to middle of caudal. Pectorals 9. No ventrals.

DEREPODICHTHYS gen. nov. (LYCODIDiE.) 



A slender deep-sea Lycodid without scales or lat(;ral line and with the ventral fins 

 reduced each to a slender uubranched lilameut, the two very closely approximated, 

 springing from a common projecting base, which is located far forward below the 

 eye, as in Ophidioids. Gill-opening a narrow vertical slit, little wider than base of 

 pectorals. Teeth cardiform, curved, few in number, in narrow bands or irregular 

 single series on jaws, vomer, and palatines. 



Derepodichthys alepidotas, type. 



135. Derepodichthys alepidotus sp. nov. 



Head and body very long and slender, the former resembling a Lycodes in appear- 

 ance, being moderately compressed, with a tiattish occiput and a gently rounded, 

 decurved rostral profile. Mouth slightly oblique, quite at lower side of snout, the 

 lower jaw shorter, fitting within the upper. Maxillary and premaxillary entirely 

 concealed within the thick skin of the upper lip, which is directly continuous with 

 that of the forehead, the upper jaw being therefore nonprotractile. Angle of mouth 

 under front of pupil, its distance from tip of snout 2* in head. Teeth as described 

 under the genus. Eye small, not filling the elongate orbit, the diameter of exposed 

 portion of eyeball slightly less than three-fourths length of snout, the latter 3J in 

 head. A series of large mucous pores on snout and lower part of cheeks ; a second 

 series on mandible; no pores on body. Gill-slit vertical, not continued forward, its 

 loAver end slightly above base of lower pectoral rays. Length of slit one-fourth 

 length of head, slightly less than distance between slits. Head 8i in total length 

 depth of head and body 2^ in head; width of head 2} in its length. Distance from 

 tip of snout to base of ventrals 2Jt in length of head. Distance from tip of snout to 

 front of dorsal 5i in total length; from tip of snout to vent 3| in total. 



Pectorals long and slender, reaching half way to vent, IJ in head. Dorsal and 

 anal confluent with the caudal, concealed in the thick integument so that the rays 

 can not be counted. 



Color in spirits light brownish, the dorsal and pectorals whitish, the anal with a 

 dark margin, which becomes black posteriorly. Lips dusky. Abdominal region 

 blue-black. 



A single specimen, 110 mm. long, dredged oflf Queen Charlotte Island, station 3342;
