DEREPODICHTHYS gen. nov. (LYCODID.) 
A slender deep-sea Lycodid without scales or lateral line and with the ventral fins 
reduced each to a slender unbranched filament, 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 alepidotus, 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 flattish 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 22 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 34 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 
lower end slightly above base of lower pectoral rays. Length of slit one-fourth 
length of head, slightly less than distance between slits. Head 8} in total length 
depth of head and body 2+ in head; width of head 22 in its length. Distance from — 
tip of snout to base of ventrals 2} in length of head. Distance from tip of snout to 
front of dorsal 54 in total length; from tip of snout to vent 3% in total. 
Pectorals long and slender, reaching half way to vent, 14 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. /
