8. Pomotis catesbyi Cuvier & Yaloncienues. 



Hist. N:it. (les Poiss. vii, 4G9. 



As commonly supposed, this species is Eupomotis aureus [Pomotis vul- 

 garis C. & v.). 



9. Pomotis ravenelii Ciivier & Valenciennes. 



Hist. Nat. des Poiss. vii, 489. 

 This species is anUupo^notis, probably aureus, as supposed by me (Bull. 

 U. S. Nat. Mu3. s, 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 Fomofis incisor C. & V» 

 (1. c. p. 440), belong to the species called by me Lepomis paUidus. 



11. Pomotis solis Cuvier & Valenciennes. 



Hist. Nat. des Poiss. vii, 458. 



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

 probably belong to Eupomotis aureus. 



12. Plesioperca anceps Vaillant. 



(Nonvelles Archives du Mus6um d'Hist. Naturelle, tome 9, p. 37, 1873.) 

 As already supposed by the present writer, this species is the Hadrop- 

 terus nigrofasciatns Agassiz. 



13. Eesox deprandus Le Sueur. 



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

 The type of this species, a large stuifed shin, is an ordinary Esox 

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



14. Leuciscus gardoneus Cuv. & Val. 



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

 Ckondrostoma gardoneum Cope, Trans. Am. Phil. Soc. 1866,393.) 

 The single typical specimen of this species agrees with Noteniigonus 

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

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

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

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

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

 as N'otemigonus 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 other characters," is not reconcilable with 

 my ideas of the genus Ckondrostoma. 



15. Leuciscus spirlingulus Cuv. & Val. 



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



The types are small specimens of Luxilus cornutus (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. U. 

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