sideward. Tongue and roof of moutli papillose and toothless. Gill 

 rakers tubercular. Nostrils single, in a very short wide tube, which is 

 nearer eye than cleft of mouth. Gill opening oblique, entirely above base 

 of pectorals, the length of slit equaling snout and \ eye. A series of 

 6 pores along under side of mandible and interopercle ; none on pre- 

 opercle; 3 above premaxillary, and 2 pairs on snout; no pores along 

 side of body. Sucking disk extremely small, little more than \ diam- 

 eter of orbit, its center and the middle of pupil equidistant from tip of 

 snout; disk separated from vent by a trifle less than its own diam- 

 eter. Pectorals forming a continuous lamella, following the margin of 

 gill ilap and lower jaw, the 2 fins becoming closely approximated in front 

 of sucking disk; fin not notched, the rays decreasing regularly forward, 

 8 to 10 of the anterior rays exserted and elongated, the anterior 4 or 

 5 becoming again shorter and thicker, and wholly free from the mem- 

 brane; pectorals scarcely reaching front of anal, f to i length of head; 

 dorsal beginning over gill slit, the distance from origin of anal to snout, 

 2\ in length; fins all enveloped in thin lax skin, so that it is impossible 

 to count rays accurately without dissection; posterior dorsal and anal 

 rays well overlapping base of caudal, their membranes joining middle 

 of caudal rays. Color light rose-red on body and fins, abdomen usually 

 dusky ; inner face of pectorals, caudal, posterior portions of dorsal and 

 anal, and inside of mouth and gill openings black; peritoneum silvery, 

 with more or less black specking, sometimes nearly black. Several 

 specimens, the longest about 6 inches long, from Albatross Stations 2840, 

 2891, 2892, 2925, and 3076, in depths from 178 to 339 fathoms off the coast 

 of California and Oregon. (Gilbert.) (/^f'Aas black; ovpd tail.)

Head 5^^ in total length, its depth |, and its width f its length. An ex- 

 tremely elongate form, depressed l)ut narrow anteriorly, the head as seen 

 from above appearing shovel-shaped, with truncate snout; nape not 

 elevated and the cheeks not gibbous ; width anteriorly everywhere ex- 

 ceeding depth ; mouth inferior and transverse, overlapped by the short, 

 depressed snout for a distance equaling diameter of pupil; width of 

 mouth nearly twice distance from symphysis of lower jaw to angle of 

 mouth, the latter reaching vertical from snout to front of pupil. Teeth 

 small, weakly tricuspid, in narrow bands, lower jaw containing 10 series 

 in each half, the upper 11. Eye large, 1^ in total interorbital wddth, 

 equaling length of snout, 3i in head. Nostrils with a very short tubular 

 rim. Mucous pores large ; texture of head and body firmer than in most 

 deep-sea Liparids. Gill opening reduced to a narrow slit entirely above 

 tlie pectorals, its width equaling i diameter of orbit. Opercle produced 

 into a narrow spinous process, forming, with its membranaceous flap, a
