MYZOPSETTA, Gill. 



Myzopsetta ferkuginea, Gill. 



Platessa ferruginea St. Rep. 41, pi. 2. 

 Pleuronectes ferrugineus Gthr., Cat. iv., 447- 

 Hab. Massachusetts to New York. 



LIMANDA, Gottsche. 



LlMANDA EOSTRATA, Gill. 



Platessa rostrata H. R. St., Boston Journ. N. H. v., 268. 

 Myzopsetta rostrata Gill, Cat. 51. 



This species, referred with doubt to Myzopsetta in the "Catalogue of the 

 Fishes of the Eastern Coast," belongs probably to Limanda. 



Hab. Labrador. 



LIOPSETTA, Gill. 



This genus is proposed for the reception of the Platessa glabra of Storer, 

 well distinguished by its form and details of structure, as well as its " per- 

 fectly smooth body," an almost anomalous character in the group of genera 

 to which it belongs. 



LlOPSETTA GLABRA, GUI. 



Platessa glabra St., Boston Proc. i., 130; ib, Mem. Am. Ac. viii., 393, pi. 31, 

 f. 1. 

 Hab. Massachusetts. 



Subfamily HIPPO GLOSSINJE Gill. 



HIPPOGLOSSOIDES, Gottsche. 

 Citharus Reinhardt. 

 Drepanopsetta Gill. 



Misled by the ambiguity of the description by Fabricius of the lateral line 

 of Pleuronectes platessoides, " Linea lateralis humilior, recta medietatem 

 oculorum spectat, ventriculum tamen arcu ambiens angulo aperturse branchialis 

 summo terminata," I proposed for it the generic designation Drepanopsetta. 

 That species, however, possessing, like Hippoglossoides limandoides, a straight 

 lateral line, and otherwise agreeing so far as known, Drepanopsetta must be 

 considered as a mere synonyme of the latter. 



Hippoglossoides platessoides Gill. 



Pleuronectes platessoides Fabr., F. G. 164. 

 Platessa platessoides St., Syn. 

 Citharus platessoides Reinh., Kr. 

 Drepanopsetta platessoides Gill, Cat. 

 Hab. Greenland and Newfoundland, (Gill.) 



POMATOPSETTA Gill. 



POMATOPSETTA DENTATA Gill 



Platessa dentata Storer, Rep. 

 Hippoglossoides dentatus Gill, Giinther. 



This species has been erroneously identified with the Pleuronectes dentatus 

 of Mitchill, who described under that name a species of Chcenopsetta, distinct 

 from the one so named by Linnaeus. I propose, however, to retain as its 

 name Pomatopsetta dentata, since the Pleuronectes dentatus of Mitchill be- 

 longs to a widely different genus. 



This is slated by Dekay to be "the summer flounder ," and to be "extremely
