cheeks tumid and translucent. No 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 8 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 progressively shortened, the longest 1\ in head; ventrals moder- 

 ate, I, 3, reaching vent, 2^ in head; caudal rounded. Color creamy 

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

 whitish patches; 5 black spots on lower jaw; top of head blackish; a 

 narrow blotch at shoulder; a wider one across first dorsal; a broad 

 one on second dorsal abruptly broadened on body, then narrowed, 

 extending across anal; an irregular bar at base of caudal; a narrow 

 bar and some spots and streaks on the fin; pectoral with 2 curved bars, 

 the inner concave, the outer convex backward, the two inclosing a 

 rounded pinkish or deep orange area. (Jordan and Gilbert.) Alaska 

 to Puget Sound, rather common in water of moderate depth; a remark- 

 able little fish, evidently a degraded Cottoid. Here described from 

 specimens from Unalaska. This species is taken abundantly in shallow 

 water about Kadiak, south of the Alaskan Peninsula, thence westward 

 through Unimak Pass, along the northern shore of Unalaska Island to 

 Iturup Island, and the Pribilof Islands and in Bristol Bay. The 

 depths range from 38 to 121 fathoms. It has been also dredged by 

 Dr. Schmidt off Cape Pestschuzoff, coast of Korea.

 (graUator) . 



Body moderately elongate, tapering into a long and slender tail, the 

 nuchal region elevated. Head large, not compressed or depressed. 

 Eye very large. Preorbital broad. Mouth horizontal, lower jaw 

 included, maxillary extending a little beyond anterior margin of 

 pupil. Teeth in villiform bands on jaws, vomer, and palatines. 

 Gill openings wide, the gill membranes broadly united, free from the 

 isthmus. Gill rakers short, club-shaped; a small oval slit behind last 

 gill arch. Suborbital stay distinct, covered by the rough skin. Nasal 

 spines present; a stout spine before eye; a much larger one on upper 

 rim of orbit; a divided spine at nape; 2 small ones on lower mar- 

 gin of preorbital; a large hooked spine at angle of preopercle; 2 

 smaller sharp spines below the latter; a blunt spine on upper edge of 

 opercle. Skin close set with velvety prickles. Lateral Line distinct,
