THE FISHES OP BERING SEA. 469 



membranes broadly united to isthmus, the gill opening extending a little below the 

 lower edge of pectoral. Skin covered with close-set villous prickles, among which 

 large ones are frequently seen arranged in rather definite longitudinal series, of 

 which there may be two or three parallel with the back and one running near lower 

 line of tail. No smooth areas on sides. Lateral line conspicuous, the plates with 

 short spines directed backward. 



Dorsals separate, the first not notched, comparatively low; the first spine highest, 

 1% in head in type; in other specimens I4 to 1^ in head. Soft dorsal and anal also low, 

 none of the rays reaching base of caudal when depressed. Pectoral longer than head; 

 ventrals IJ to 2 in head. 



Color dull light olivaceous, mottled with darker;' three or four dark bands below 

 soft dorsal, one below spinous dorsal; a black band through eyes and across cheeks, 

 extending onto branchiostegal membranes; seven dusky spots along lateral line, a 

 conspicuous pink blotch, rather larger than pupil, between first and second spots. 

 First dorsal dusky; second dorsal, anal, and pectoral dotted and checked; caudal 

 with faint finely checked cross lines, which deepen to form a dark bar at its base and 

 a broader one toward its tip; ventrals pale; belly mottled. 



One specimen 6 cm. long, from station 3635, ofl' Zapadni rookery, St. George 

 Island, in 23 fathoms. 



Another specimen, barely an inch long, was dredged in 7 fathoms in the harbor 

 of Unalaska. Very numerous specimens were obtained by the Albatross in 1890 in 

 Bristol Bay and south of the Alaskan Peninsula. It was at that time incorrectly 

 identified by Dr. Gilbert with N'. oculofasoiatus. In five specimens of those from 

 Bristol Bay the dorsal contains VIII or IX — 23 or 24 rays, the anal 16 or 17, the 

 pectoral 15 or 16. 



Dr. Bean records Nautiehtliys oculofasoiatus from Unalaska, Adakh, Kiska, and 

 St. Paul. Perhaps he had the present species instead of the more southern Nautich- 

 thys oculofasoiatus. The genus Nautiscus Jordan and Bvermann is closely allied to 

 Nautiohthys, differing in the low spinous dorsal, the base of which is scarcely raised 

 above the nape. The skin is rougher than in Nautichthys, and the anal fin is shorter. 



118. Psychrolutes paradoxus Guntlier. 



JPsychrolutes zebra Bean, Proo. U. S. Nat. Mus., 1890, X, 3. 



Head, 2|; depth, 3. D., — , 15; A., 13; P., 19; eye, 4 in head; width of mouth from 

 angle to angle, IJ; snout, 3^; interorbital, 3^. 



Body short, broad, thick, tadpole shape, the texture soft like that of a Liparid, 

 especially about the head; the skin is limp and smooth, covered with little soft dermal 

 warts, that of the head especially lax, the cheeks tumid and translucent. Ko trace of 

 spines on head, the bones all thin and weak; nostrils each in a short tube; mouth 

 broad, its cleft chiefly anterior, the jaws equal; teeth very minute, none on vomer or 

 palatines; lower jaw with eight large open pores. Gill membranes broadly united to 

 the isthmus, the gill opening extending to slightly below base of pectoral. Lateral 

 line obsolete. Dorsals united, with a slight notch between, the first buried in a ridge 

 of skin, so that its delicate spines can not be counted from without; second dorsal 

 low, similar to anal, both of them free from the caudal. Lower pectoral rays progres- 

 sively shortened, the longest 1^ in head. Ventrals moderate, I, 3, reaching vent, 2^ 

 in head; caudal rounded. 



Color creamy white, with blackish cross-bands, irregular in form and broken by
