Gillrakers slender, smooth, 14 to 16 below arch, the longest nearly one- 

 half diameter of orbit. Eyes large, separated by a narrow, knife-like 

 ridge, which is naked, or with a single series of scales. Scales small, 

 firm, rough, those on tail roughest, those on blind side similar, mostly 

 smooth anteriorl3\ Lateral line rising anteriorly, but without arch; 

 dorsal beginning innnediately in front of pupil; anal preceded by a 

 spine; caudal long; pectoral of eyed side one-half length of head; ven- 

 tral reaching past front of anal; pectoral and ventral of eyed side with 

 prickle-like scales. Brownish, nearly uniform, sometimes spotted 

 with darker; fins gra3dsh, irregularly blotched with dusky. Body 

 sometimes sinistral. Length, 18 inches. Bering Sea south to Cape 

 Flattery; a rather abundant shore fish in Puget Sound, and it seems to 

 be still more common northward, being, in Alaska, a food-fish of 

 some importance. Abundant north and south of the Aleutian Islands 

 and in Bristol B^y. Recorded b}^ Schmidt from the Sea of Okhotsk. 



Our specimens from Kamchatka agree in all respects; D. 77 to 84; 

 A. 60 or 61. Pectoral not quite one-half head. Interorbital ridge 

 sharp, with 1 series of scales; gillrakers ,/' -|- 14.

Head, 2>\ in length; depth, 2|; longest diameter of upper eye, 3^ in 

 head; snout (measured from upper eye) 5 in head; maxillary of colored 

 side, 2iT, of blind side, 2^, in head; depth of caudal peduncle equaling 

 its lengtl, ?)i in head; D. 72; A. 56; P. 11; pores in lateral line 91. 

 Upper profile of head continuing the dorsal curve without interrup- 

 tion, there being a slight depression above the eye and an increased 

 corivexitj' o\s. the snout; mandible ver}' heavy, projecting anteriorly, 

 so that its symphyseal profile completes the curve of the snout; a very 

 short prominence at symphvsis directed verticalh^ downward; gape 

 strongly curved and the mouth narrowed anteriorly, so that the max- 

 ilhuy and premaxillary are almost wholly concealed along the middle 

 of their length by the overarching prefrontal; teeth acute, in a single 

 series in each jaw, all except the anterior teeth in each jaw short; at 

 the symphysis of lower jaw the teeth are longer and directed inward, 

 while in the anterior end of each premaxillar}^ the teeth are still more 

 enlarged, and the series on each side describes a strong curve with its 

 convex side toward the median line; maxillary reaching vertical from 

 slightly ])eliind middle of lower eye; nostril tubes conspicuous, the 

 anterior in closest proximity to the upper lip, which it entirely over-
