[15] FLOUNDERS AND SOLES. 239 



Habitat. — North Pacific, in rather deep water. San Francisco to Pu- 

 get Sound, and probably northward. 



This small flounder is brought in in large quantities by the sweep- 

 nets off San Francisco. It is of little value as a food-fish. 



Genus V.— EOPSETTA. 



Eopsetta Jordan & Goss, Cat. Fish. N. A., 1835, 135 {jordani). 



Type: Hippoglossoides jordani Lockington. 



This genus contains but a single species, a large flounder which is 

 abundant on the coast of California. It is very close to the genus 

 Hippoglossoides, and its separation as a distinct genus is perhaps hardly 

 justified. 



ANALYSIS OF SPECIES OF EOPSETTA. 



a. Body broadly ovate ; maxillary 2f in head ; teeth in two series above, the inner 

 series much smaller, the outer canine-like in front, gill membranes somewhat 

 united; gill-rakers strong, x + 15; eyes large, 3| in head, separated by a narrow, 

 blunt, scaly ridge; scales small, firm, strongly ciliated, smooth on blind side; 

 anal spine strong ; head 3J ; depth 2£. D. 94, A. 72, Lat. 1. 96. Vertebne 11 -f 32 

 =43. Color, olive-brown, nearly uniform Jordani, 5.

Habitat. — Coast of California, Puget Sound to Monterey. 



This is one of the commonest flat-fishes of the California coast, be- 

 ing found in abundance in shallow water from Monterey northward. 

 It is a good food-fish, and large numbers are dried each year by the 

 Chinese. 



Genus VI— HIPPOGLOSSOIDES. 



Hippoglossoides Gottsche, Wiegmanu's Archiv, 1835,164 (" limanda" = platessoides). 

 Drepanopsetta Gill, Cat. Fish. East Coast N. Am., 1861,50 (platessoides). 

 Pomatopsetta Gill, Proc. Ac. Nat. Sci. Phila., 1864, 217 (" dentata "— platessoides). 



Type : Pleuronectes platessoides Fabricius. 



This genus, as here restricted, contains two closely related species, 

 the one of the North Pacific, the other of the North Atlantic. Both are 

 essentially Arctic species, inhabiting shallow waters in the regions 

 where they are. most abundant.
