Further, A. oligaspis agrees in many points with Alhurnellus cli- 

 lectus, Girard, in Proc. Ac. Nat. Sc. Philad. 1856, p. 193, and in 

 U. S. & Pac. li. R. Exp. Fish. p. 259, pi. 57. figs. 9-12 ; and still 

 hcttevwith Alb u melius mnbratilis, Girard, P. A. N. Sc. Philad. I. c; 

 and in U. S. & Pac. R. R. Exp. Fish. p. 260,— both these fishes 

 having been obtained in Arkansas. It is impossible to point out 

 real specific differences without a reexamination of the typical ex- 

 amples. 



Still more obscure are AlbwneUus amabilis, Girard, Proc. Ac. Nat. 

 Sc. Philad. 1856, p. 193 ; and U. S. & Mex. Bound. Ichthyol. p. 51, 

 pi. 29. figs. 10-13, from Texas ; Alburndlus megalops, Girard, I. c. 

 1°, & I. c. 2°, p. 52, pi. 29. figs. 1-4, from Texas ; Alhurnellus 

 socius, Girard, I. c. 1°, & I. c. 2°, pi. 29. figs. 14-17, from Texas ; 

 Alburnus lepidulus, Girard, I. c. 1°, p. 212, from Black Warrior 

 River, Alabama,
