A few specimens apparently identical with others from the Ohio Eiver. 

 This species, like Lepioponms paUidus, Apomotis cyanellus, Campostoma 

 anomalum, Notemigonus chrysoleucus, and Aniiurus natalis, mentioned in 

 this paper, is one of those widely diffused and variable, species the 

 occurrence of which almost anywhere east of the Pacific slope need not 

 surprise any one. 



Genus ALBUENOPS Girard. 



(Hyiopsis of Cope, etc., but probably not of Agassiz.) 



10. — Alburnops missuriensis (Cope) Jordan. 



1872 — Hyiopsis missuriensis Cope, Hayden Survey Wyoming, 1870, 437. 



Hybopsis missouriensis Jordan & Copeland (1876), Check List, 150. 

 Sybojysis missuriensis Jordan (1878), Man. Vert. ed. 2d, 291. 



il^umerous specimens, agreeing closely with Professor Cope'$ descrip- 

 tion, except that the distended stomachs make the apparent depth pro- 

 portionally greater. The teeth are 4 — 4, with strong masticatory sur- 

 face ; the scales are extremely large, 5 — 30 — 3. The mouth is oblique in 

 position and scarcely inferior. The dorsal fin is over the ventrals. In 

 color, these specimens are pale and silvery. 



Genus CYPRINELLA Girard. 

 11. — Oyprinella bubalina (Baird & Girard) Girard. 



1853 — LeucisGus hiibalinus B. & G. Proc. Ac. Nat. Sc. Phila. 391.

 1856 — Cyprinella umbrosa Girard, Proc. Ac. Nat. Sc. Phila. 197. 



. Cyprinella umbrosa Girard (1858), U. S. Pac. R. R. Expl. 260, pi. 58, f. 1-5. 



Cyprinella umbrosa Jordan & Copeland (1870), Check List, 153. 



Many specimens of a very deep-bodied species of Cyprinella^ agreeing 

 well with both G. huhalina and C. umhrosa of Girard. As my specimens 

 can be readily identified with either, I unite the two nominal species in 

 the above synonymy. The male specimens have the snout profusely 

 tuberculate. The teeth are 1, 4 — 4, 1, slightly crenate.
