rugose ridge above opercle, with a smaller similar ridge behind it; both 

 sides of jaws with teeth, those 011 blind side stronger; origin of dorsal 

 over middle of upper eye. Color brown, with vague dusky spots; 6 or 7 

 blackish vertical bars on dorsal and anal; similar lengthwise blotches on 

 caudal. Okhotsk Sea, east to Kamchatka. (Steindachner.) Not seen by 

 us. From the excellent figure we conclude that it belongs to Fseuclo- 

 pleuronectcs, although its pharyngeals have not been described. It seems 

 to us nearer to P. americanus than to Liopsetta ylacialis. (pinna, fin; 

 fasciatus, banded.)

Body oblong, with firm flesh. Mouth small, teeth uniserial, incisor-like, 

 compressed, forming a continuous cutting edge. Lateral line straightish, 

 without arch or accessory dorsal branch. Scales imperfectly imbricated, 

 chiefly cycloid in both sexes ; lower pharyngeals small and narrow, sepa- 

 rate, each with 1 or 2 rows of small bluntish teeth. No stellate scales 

 along bases of dorsal and anal. Species mostly European ; valued as food.

Head 3 ; depth 2. D. 68 ; A. 50 ; scales 78. Mouth very small, with small, 

 incisor-like teeth, rounded at tip. Eyes separated by a narrow ridge ; about 

 5 small, prominent, conical, obtuse, bony tubercles in a row above the oper- 

 cle, continuous with the direction of the lateral line, which is straight, 

 without accessory dorsal branch ; tubercle above opercle largest. Scales 

 small, cycloid in all specimens examined. Anal spine present. Grayish, 

 mottled with paler and with round black spots; fins very dark. Bering 

 Sea on both coasts, south to Kadiak; not common. Our specimens from 

 Avatcha Bay, Bristol Bay, Herendeen Bay, Chernofsky Harbor, Grantley 

 Harbor, Chignik Bay, and Robben Island. The above description from a 

 small specimen (No. 28025, U. S. Nat. Mus. ) collected by Mr. W. J. Fisher at 

 Kadiak. The species proves, as suspected by Jordan & Goss, to be a true 

 Pleuronectes, having the lower pharyngeals narrow, separate, with 2 rows 

 of bluntish teeth, (quadrituberculatus, having four tubercles.)
