8. Pomotis catesbyi Cuvier & Valenciennes. 



Hist. Nat. des Poiss. vii, 469. 



As commouly supposed, this species is Ewpomotis aureus {Pomotis vul- 

 garis C. & Y.)- 



9. Pomotis ravenelii Cuvier & Valenciennes. 



Hist. Xat. (les Poiss. vii, 469. 



This species is an Uupomotis, probably aureus, as supposed by me (Bull. 

 U. S. j^at. Mus. X, 38), but the types are too far decayed for certain 

 identification. 



10. Pomotis gibbosus Cuvier & Valenciennes. 



His. Nat. des Poiss. vii, 467. 



The types of this species, as well as those of Pomotis incisor 0. & V. 

 (1. c. p. 446), belong to the species called by me Lepomis pallidus. 



11. Pomotis solis Cuvier & Valenciennes. 



Hist. Nat. des Poiss. vii, 468. 



Only the Philadelphia specimens seen. These are badly decayed, but 

 probably belong to Eupomotis aureus. 



12. Plesioperca anceps Vaillant. 



(NouAelles Archives du Museum d'Hist. Naturelle, tome 9, p. 37, 1873.) 



As already supposed \>y the present writer, this species is the Hadrop- 

 terus nigrofasciatus Agassiz. 



13. Esox deprandus Le Sueur. 



(Le Sueur MSS., Cuv. & Val. Hist. Nat. des Poiss. xviii, 336.) 



The type of this species, a large stuffed skin, is an ordinary Esox 

 lucius L. The cheeks, as usual, are scaly ; the opercles naked below. 



14. Leuciscus gardoneus Cuv. & Val. 



(Hist. Nat. des Poiss. xvii, 316 ; Giintlier Cat. Fishes Brit. Mus. vii, 258. 

 Choudrostoma gardonettm Cope, Trans. Am. Phil. Soc. 1866,393.) 



The single typical specimen of this species agrees with Notemigonus 

 chrysoleucus in most respects, differing chiefly in the short anal (9 or 10 

 developed rays). It must be referred to the genus Notemigonus, of 

 which it possesses the carinated abdomen, backward dorsal, and the 

 teeth 5-5, the edges of the grinding surface strongly crenate. If the 

 specimen is normal, not an accident or hybrid, the species should stand 

 as Notemigonus gardoneus. Professor Cope's statement, that the type 

 of this species (also examined by him in Paris) is " identical with Chon- 

 drostoma in dentition and otlier characters," is not reconcilable with 

 my ideas of the genus Chondrostoma. 



15. Leuciscus spirliiigulus Cuv. & Val. 



Hist. Nat. des Poiss. xvii, p. 321, pi. 506. 



The types are small specimens of Luxilus cornvius (Mitch.). 



16. Gobio cataractae Cuv. «& Val. 



Hist. Nat. des Poiss. xvi, 315, pi. 483. 



The type of this species, as already supposed by me (Man. Vert. E. IT. 

 S., ed. 2d, p. 307), is the Rhinichthys nasutus of authors, which should
