July 17, 1894, and in Scioto creek, Coopersville and Saranac 

 river, Plattsburg, July 19, 1894. 



Dr Meek found it in small numbers in Six Mile creek and Fall 

 creek below the falls. It inhabits clear running water. 



The fish grows to the length of G inches and may be at once 



distinguished from all of the other minnows by its three-lobed 



lower jaw. It is believed that this singular structure of the 



mouth enables the fish to scrape mollusks from their hold on' 



rocks, as its stomach usually contains small shellfish. It takes 



the hook readily.
