 Key to Species. 



A. Mouth inferior, horizontal, color silvery. 

 B. Teeth one-rowed, 4-4. 



C. Eye i% i n head; no plumbeous blotches along lateral line. — hyostomus. 

 CC. Eye very large, 2%; an interrupted plumbeous lateral band. — dissimilis. 



BB. Teeth two-rowed, 1, 4-4, 1, or 1, 4-4, o. 



D. Sides with a dusky lateral band. — amblops. 

 DD. Sides silvery, no lateral band. — storerianus.

Hybopsis hyostomus (Gilbert). 



Head 4; depth 5^; eye $% . D. 8; A. 8; scales in lateral line 37, 13 

 before dorsal. Body and head very slender; snout long, acute, projecting 

 beyond mouth for half its length; mouth short, wide, inferior; barbels long. 

 Color silvery, everywhere dusted with fine, dark specks. Length 2^ inches. 



Very rare in the state, and, as far as my knowledge goes, 

 confined to the Ohio river. Dr. Henshall recorded it first from 

 the Ohio river at Raccoon Island, 1889, and the writer has taken 

 it twice in the Ohio, at Ironton, May 31, 1899, an & at Bellaire, 

 August 31, 1900. 



Hybopsis dissimilis (Kirtland). Spotted Shiner. 



Head 4%; depth 5. D. 8; A. 7; teeth 4-4; scales 6-40 to 47-5, about 20 

 in front of dorsal. Body long and slender, little compressed, with long 

 caudal peduncle. Head long, flatfish above; snout somewhat bluntly 

 decurved, a little projecting; mouth small, horizontal, lower jaw included; 

 barbel smaller than in H. amblops; eye about 3 in head, somewhat directed 

 upward. Color above dusky or olivaceous, somewhat mottled; sides silvery, 

 with a bluish lateral band, which is sometimes widened into several blackish 

 blotches. In full coloration, one of the most striking of our Minnows. 



This species has been taken in a number of localities in Ohio, 

 and in both the lake and Ohio river drainage, but is nowhere com- 

 mon! Recorded by Kirtland for the Mahoning river and Lake 

 Brie near Cleveland; Hamilton County, "rather common in 

 Little Miami river and O'Bannon creek," Henshall, 1888 ; Frank- 

 lin County, " Big Walnut creek, rare," Williamson and Osburn, 

 1897 ; Stillwater creek near Dayton, rare, R. C. Osburn, 1899 ; 

 Cuyahoga river at Hawkins, R. C. Osburn, 1900.
