This fine darter is rather common throughout the whole State in 

 large creeks and small rivers, being especially abundant in the 

 Wabash Valley and in the Little Wabash, Saline, and Embarras 

 Rivers. A few specimens were taken also in the Illinois.

(Bui. II, 39; Alvordius phoxocephalus: Synop., 501; do.) 



This species, described from specimens taken in Central Illinois, 

 has not yet been found in the northern part of the State, although 

 it is decidedly common from the Illinois River southward, including 

 the Wabash Valley. It occurs in our collections only from the 

 larger streams ; such as the Fox, Illinois, Saline, and Little Wabash 

 Rivers, and Mackinaw Creek.

 the northern part of the State. Our collections contain specimens 

 from the borders of Lake Michigan to Cairo and the Wabash Valley.

 creeks.
