284 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [60] 



ANALYSIS OF SPECIES OF PAROPHRYS. 



a. Body elongate-elliptical ; snout very prominent, forming an abrupt angle with the 

 descending profile ; eyes large, 4-i- in head, separated by a very narrow, high ridge? 

 the upper eye encroaching on the dorsal outline ; teeth small, trenchant, widened 

 at tip ; lin-rays scaleless ; scales cycloid, those on cheeks usually ciliated, espe- 

 cially in northern specimens ; head 3| ; depth 21 ; D. 74 to 86 ; A. 54 to 68 ; lat. 

 1. 105; vertebras H + 33—44; uniform light olive-brown; the young sometimes 

 spotted with blackish Vktulus, 71. 



71. PAROPHRYS VETULUS.

Pleuronectes vetulus Jordan and Gilbert, Synopsis Fish. N. A., 1882, 831. 



Plcuroiiectes digrammus Giinther, Cat. Fish., iv, 445, 1862 (Victoria). 



Parophrys hubbardi Gill, Proc. Ac. Nat. Sci. Phila., 1882, 281 (San Franciscft). 



Habitat. — Pacific coast of North America, Alaska to Santa Barbara. 



This small flounder lives in waters of moderate depth. It is, next to 

 Platichthys stellatus, probably the most abundant of the flounders of 

 the California coast. 



Genus XXIX.— IXOPSETTA. 



Inopsetta Jordan & Goss, Cat. Fish. N. A., 1885, 136 (ischyrus). 



Type: Parophrys ischyr us Jordan & Gilbert. 



This genus contains a single species, closely allied to Platichthys stel- 

 latus, but separated from it by the curious character common to many of 

 our Pacific coast flounders, of having an accessory branch to the lateral 

 line. In technical characters there is not very much to separate Inop- 

 setta from Parophrys, though the resemblance between I. ischyra and P. 

 vetulus is not very close. 



ANALYSIS OF SPECIES OF INOPSETTA. 



a. Body oblong, robust ; snout projecting, forming an angle with the profile ; teeth 

 narrow incisors; interorbital space rather broad, scaly; eyes large; lower 

 pharyngeals each with two rows of coarse, blunt teeth ; scales thick, firm, ad- 

 herent, loosely imbricated, all ctenoid on both sides of body, those on head 

 roughest ; accessory lateral line short. Head 3£; depth 2. D. 70 to 76 ; A. 52 to 

 57 ; lat. 1. 85. Light olive-brown, with dusky blotches, blind side more or less 

 spotted or tinged with rusty Ischyea, 72. 



72. INOPSETTA ISCHYRA.
