edges; snout obtuse, gently curved, its length from upper orbit, 

 0.04; dorsal outline of snout at right angles to upper margin of 

 premaxillary; maxillary of eyed side reaching vertical of anterior 

 margin of pupil; upper jaw strongly arched upward and outward 

 anterior to the lower eye; posterior edge of maxillary broad, its 

 greatest width, 0.025; length of maxillary of eyed side, 0.065, of 

 blind side, 0.07; teeth blunt, in a somewhat irregular row, often 

 truncate, some even indented; gill-rakers short and stout, 7 -J- 10, 

 the longest, 0.013. 



Body oval, rather robust, its width 0.20 of its depth; depth of 

 caudal peduncle, 0.11; tip of mandible to anus, 0.29 (varying to 

 0.33); the anus partly on blind side. 



Scales spinous on eyed side, cycloid on blind side (scales rough 

 on both sides in larger specimens). Lateral line with a moderate 

 arch in front, 6 rows of scales between its highest part and the hori- 

 zontal portion, height of curve 11 in straight part, its length 3.5 in 

 straight part (varying to 3 in larger specimens) ; one branch of lateral 

 line extends sharply upward from the nape, for most of its length 

 parallel to the bony ridge; the suborbital branch extends as a semi- 

 circular arch to tip of maxillary, clearing the lower margin of orbit 

 by 0.012, with 18 (to 20) pores; interorbital with 1 or 2 uneven rows of 

 cycloid scales (often with 3 rows of ctenoid scales in larger speci- 

 mens) ; tips of snout, lips of both sides, and the exposed portion of the 

 opercular bones and the ridge anterior to nape on the blind side 

 naked. Fins on eyed side with a few small scales on rays. Dorsal 

 beginning on median line over anterior border of pupil, rising to the 

 fortieth ray, its greatest height 0.13, distance from tip of snout to 

 base of highest dorsal ray, 0.58; fleshy tips of rays free; anal sim- 

 ilar, its highest ray about middle of fin; anal spine present; caudal 

 slightly rounded, 0.20; pectorals broad and rounded, each of 11 

 rays, length, eyed side, 0.16, blind side, 0.11; ventral of blind side 

 slightly anterior, length of each, 0.10, extended to second anal ray; 

 each ventral of 6 rays. 



Color brown, with irregular spots of constant position, 1 spot 

 on lateral line at about the middle of its straight part, 5 to 8 above 

 the lateral line below the dorsal base a distance about equal to the 

 diameter of the eye; similar spots near anal fin, and others in 

 various positions; about 8 vertically elongate spots on dorsal, about 

 7 on anal, in addition to which all the fins of the eyed side are finely 

 spotted. The spots are less evident in larger specimens. "The 

 lower side of the vertical fins is always yellow." l 



An adult female, 289 mm. long without caudal, from Aniwa Bay, 

 Sakhalin Island, is identical with specimens from Alaska. Dorsal, 

 70; anal, 54; pores, 80; gill-rakers, 6-8; length of head, 0.25;
