I Hippoglossina Steindachner. 



(Steiudachuer, Ichth. Beitr. V, 13, 1876; type HippoglossMa macrops Steindachner.) 



This genus is very close to Faralichthys, differing chiefly in the dentition, the teeth 

 eing small and uniform in size, arranged in a single row. The scales are ctenoid. 

 'a he eyes are unusually large iu the single known species, which bears a remarkable 

 i\ semblance to Hippoglossoides jordani. The lateral line is however anteriorly arched 

 iii Hippoglossina, but straight in the latter species. (Name a diminutive of Hippo- 

 gloss us. ) 



Hippoglossina macrops SteindacLner, 1. c. Mazatlan, probably from rather deep water. 



2 Eopsetta Jordan & Goss, subgenus nova, for Hippoglossoides jordani Lockington 

 [rfv?, excellent ; jpijrra, flounder), characterized by the biserial upper teeth and by 

 other peculiarities. ^ 



^ Lijopseita Jordan &■ Goss, subgenus nova, for Hippoglossoides exilis Jordan & Gilbert 

 (XvGo, to loosen; 2p7jrra, flounder), characterized by the large, loose scales, biserial 

 upper teeth, and feeble structure.
