on the right side rough ctenoid, those on the left side nearly or 

 quite smooth; scales on body rougher than cheeks; caudal pedun- 

 cle short, higher than long; dorsal inserted over eye, its middle 

 rays highest; pectoral less than two-fifths head; caudal rounded; 

 anal spine present ; lateral line simple, with a rather low arch in 

 front; a concealed spine behind ventrals; ventral of colored side 

 partly lateral, the other wholly so; anal spine strong. Brownish

PSEUDOPLEURONECTES. 



Body oblong; the scales firm, strongly ctenoid on eyed side in
