Inopsella, {Jordan and Goss) Jordan, 1887, Rep. U.S. Com. Fish., xiii, (1885), p. 924 [Parophrys 

 ischyrus, Jordan and Gilbert] ; Jordan and Evermann, 1898, Bull. U.S. Nat. Mus., xlvii (3}, p. 

 2641 ; Norman, 1933, Ann. Mag. Nat. Hist., (10) .\i, p. 221. 



Apparently related to Liopselta and Platichthys. Teeth close-set, incisor-like. 

 Lower pharyngeals each with 2 rows of coarse, blunt teeth, the inner row partly 

 differentiated into an inner and a posterior series. Scales similar in both sexes, strongly 

 ctenoid on both sides of body, those on head nearly tuberculate. Supratemporal 

 branch of lateral line with a short posterior prolongation. 



A single species from Puget Sound. 



This genus has been associated by .-Xmerican authors with Parophrys, Isopsetta 

 and Lepidopsetta, on account of the short posterior prolongation of the supratemporal 

 branch of the lateral line. It is possible that the single known " species " of Inopsella 

 from Puget Sound may prove to be a hybrid between Lepidopsetta bilineata and 

 Platichthys siellatiis.
