This largest of Ohio darters is widely distributed over the 

 state and generally common. It is found in the quiet waters of 

 streams of all sizes (but more commonly in the larger ones), and 

 in lakes, on gravelly or sandy bottom. Given by Rafinesque for 

 the Ohio and Miami. Kirtland reported it "common," and 

 Jordan, " generally abundant." Hamilton County, " common in 

 Little Miami river and Ross lake," Henshall, 1888; Lorain 

 County, " not very common, taken both in rivers and the lake, 

 abundant in Sandusky Bay and Put-in-Bay, and it formed the 

 bulk of the fishes that I saw among the terns' nests on Rattle 

 Snake Island," McCormick, 1892 ; Maumee river system, rather 

 common, nearly all streams, Kirsch, 1893 5 Franklin County,

To the northward this species is represented by the following 

 variety : 



Percina caprodes zebra (Agassiz). Manitou Darter. 



This variety is found in the northern part of the state, with the typical 

 caprodes. It is known chiefly by the lack of scales on the nuchal region, the 

 rather more slender form, and the shorter vertical bars. It intergrades with 

 the typical caprodes. 



The Manitou Darter has been recorded for the state by 

 McCormick in Lorain County, 1892, as " occuring with the typi- 

 cal form in proportion of about 1 to 3, some specimens showing 

 intermediate stages;" Lake Erie at Sandusky, Cuyahoga river 

 at Hawkins, and Grand river at Painesville, R. C. Osburn, 1900.
