dines, maculosa, macrophthalma, etc., constitute the 

 genus Harengula, well separated from Sardina and 

 Sardinella by their firm flesh and adherent scales. 



The type of Etheostoma should be E. blenni- 

 oides. The name should replace Diplesion, while the 

 genus called Etheostoma by Jordan and Evermann 

 should stand as Poeeilichthys. Some of the sub- 

 genera in this group should stand as distinct genera. 



The genus called Centrarchus should stand as 

 Eucentrarchus Gill and the family of Sun-fishes and 

 Black Bass, as Micropteridae. 



The name Gerres Cuvier should replace Xystce- 

 ma, while the genus called Gerres by Jordan and 

 Evermann becomes Diapterus. The family stands 

 as Eucinostomidae as there is an earlier family Ger- 

 ridae, among insects. 



Histrio Fischer replaces Pterophryne. 



Leucichthys Dybowski replaces Argyrosomus 

 (preoccupied) for the Lake Herrings and Ciscoes. 

 Several new species of these have been described by 

 Jordan and Evermann, from the Great Lakes. 



The Trout Perch of the Lakes should stand as 

 Percopsis omiscomaycus Walbaum, instead of Per- 

 copsis guttatus. The Lake Sturgeon as Aeipenser 

 fidvescens Rafinesque, instead of Aeipenser rubicun- 

 dus Le Sueur as Mr. Hubbs has noted. The Ameri- 

 can eel is Anguilla rostrata (Le Sueur, Sept., 1817), 

 instead of A. ehrisypa Rafinesque (Dec, 1817). The 

 date of rostrata is incorrectly given by Jordan & 

 Evermann. 



Membras Bonaparte replaces Kirtlandia. 



Mierometrus Gibbons replaces Abeona. 



Phyeis Rose replaces Emphyeus and Urophycis. 



Polynemus L. replaces Polydaetylus. 



The generic name Catulus is preoccupied in in- 

 sects. The genus of sharks so named becomes 

 SeyUiorliinus. 



Siphostoma Rafinesque becomes again Syngna- 

 thus, and Lucius Rafinesque reverts to Esooc, while
