296 REPORT OP COMMISSIONER OF FISH AND FISHERIES. [72] 



The male is the rough fish described by Pallas as P. cicatricosus. The 

 smoother female is Dr. Giinther's Pleuronectes franTclinii, the sexual dif- 

 ferences being much as in Liopsetta putnami. 



Indeed, as already intimated, we have little doubt that the Liopsetta 

 putnami of the Atlantic is wholly identical with Liopsetta glacialis of 

 the Arctic Ocean, and with Liopsetta dvinensis of the northern coasts 

 of Russia. 



Genus XXXVL— PLATICHTHYS. 



Platichthys Girard, Proc. Ac. Nat. Sci. Phila., 1854, 130 (rugosu8=8tellatus). 



Type : Platichthys rugosus Girard —Pleuronectes stellatus Pallas. 



This genus is composed of a single species, the largest of the small- 

 mouthed flounders, and distinguished from related forms chiefly by the 

 development of coarse stellate tubercles instead of scales. 



ANALYSIS OF SPECIES OF PLATICHTHYS. 



a. Body broad and short, very robust, the snout forming a slight angle with the pro- 

 file ; interocular space broad, with very rough scales ; tubercles or scales coarsest 

 on head and along bases of fin-rays ; lateral line without scales ; ridge above opercle 

 rough; head 3f ; depth, 2 ; D. 58;tA. 42; vertebrae 34; color dark brown, with 

 lighter markings; fins reddish-brown, dorsal and anal each with four or five black 

 vertical bauds ; caudal with three or four black longitudinal bands. .Stellatus, 87.
