286 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [62] 



Pleuronectes variegatus Schlegel, from Japan, may belong to Lepidop- 

 setta. 



The same name, Lepidopsetta, has been lately given by Dr. Glinther 

 to a very different genus of flounders. For the group so-called the 

 name M&ncopsetta of Gill should be used. 



ANALYSIS OF SPECIES OP LEPIDOPSETTA. 



a. Body broadly ovate, thickisk; teeth bluntish, subcortical : lower pharyngeals with 

 two rows of blunt teeth. Snout projecting, forming an angle ; eyes large, separ- 

 ated by a prominent scaly ridge. Scales small, mostly ctenoid, those on the head 

 very rough, especially in northern specimens (var. umbrosa); scales of the blind 

 side smooth ; accessory lateral line half length of head. Anal S|)iue present. 

 Head 3f ; depth 2i. D. 80 ; A. 60 ; lat. 1. 85. Vertebrae, 11 + 29=40. Yellowish 

 brown, with numerous round pale blotches Bilineata, 74.

 Pleuronectes perarcuatus Cope, Proc. Ac. Nat. Sci. Phila., 1873. (Alaska.) 



Habitat. — Pacific coast of North America, Alaska to Monterey. 



This species is one of the commonest of the flounders of the Pacific 

 coast, its abundance apparently increasing towards the northward. It 

 reaches a weight of five or six pounds and is an inhabitant of shallow 

 waters. Specimens from Puget Sound and northward are rougher than 

 Southern specimens and constitute a slight geographical variety, for 

 which the name of Lepidopsetta bilineata umbrosa may be used. Th's 

 is the same as the perarcuatus of Cope. 



Genus XXXII.— LIM AXDA. 



Limanda Gottsche, Wiegmann's Archiv, 1835, 100 (limanda). 

 Myzopsetta Gill, Proc. Ac. Nat. Sci. Phila., 1864, 217 (ferruginea.) 



Type: Pleuronectes limanda Linnaeus. 



This genus is closely allied to Pseudopleuronectes, from which it differs 

 only in the presence of an arch on the anterior part of the lateral line. 

 Pour species of Limanda are now recognized.
