CYPRINIDA. 6r 
Apparently a rare species in Ohio. Dr. Jordan (Ohio Rept. ) 
says: ‘‘It is found in the tributaries of Lake Erie and even in 
the lake itself. It also occurs in the southeastern part of the 
state.’’ Since then it has not been noticed by any other collector, 
and the writer has taken it but once, a single specimen from a 
small tributary of the Grand river near Painesville, August 2, 
IgOO. 
Rhinichthys atronasus (Mitchill). BLACK-NOSED DACE. 
Head 4; depth 4%; eye 1% in snout, 4% in head. D. 7 or 8; A. 7; 
scales 10-65-6; teeth 2, 4-4, 2. Body moderately elongate, little compressed. 
Head moderate, rather broad and flattish above; snout moderate; mouth 
horizontal, lower jaw included; barbels well marked in all Ohio specimens 
examined. Color above dark-yellowish olive, much blotched with black; a 
black lateral band passing forward through eye to snout; breeding males 
have the lateral band and the lower fins bright orange or crimson. All color 
markings less evident in females and young, but the lateral, dark band 
always present. 
Distributed over the state and generally common or even 
abundant in suitable localities. It is essentially a ‘‘ brook’”’ 
species, being rarely found in larger streams, but swarming in 
clear, cold spring runs, in company with Chrosomus erythrogaster. 
Hamilton County, ‘‘ common in all the streams,’’ Henshall, 1888 ; 
Lorain County, ‘‘ Spring brook and Chance creek, not common,’’ 
McCormick, 1892; Maumee river system, ‘‘ several from Lost 
creek near Cecil, by Prof. Meek, found nowhere else’’ (in Ohio), 
Kirsch, 1893; Franklin County, Grant’s Run and Plum Run, 
common, Williamson and Osburn, 1897; Knox County, Little . 
Jelloway creek, Parker’s Run, Joe Sapp Run and Shadley Run, 
tributaries of Big Jelloway creek, common or abundant, May 24 
given as a breeding date, Parker, Williamson and Osburn, 1898 ; 
Ohio river at Ironton, Huron river at Milan, Wabash river at 
Celina, Wolf creek at Dayton, North Fork of Licking river at 
Newark, in all of these cases the species has been taken in small 
nameless tributaries rather than in the main stream, with the 
exception of Wolf creek and the Ohio river, R. C. Osburn, 1899 ; 
Cuyahoga river at Kent and Hawkins, and Breakneck creek near 
Kent, R. C. Osburn, 1goo.
