The genus Ericyinba contains but a single known species and is characterized by 

 having the interopercle and bones of the mandible with externally visible mucous 

 chambers. The single species is found from western New York and Pennsylvania 

 to Michigan and Kansas and southward to Florida. It prefers clear streams, often 

 ascending small brooks, but rarely occurring in lakes. It is locally common and is 

 one of the most remarkable and interesting of minnows. It attains a length of 3 to 

 4 inches, but is not of much value as a bait minnow. It lives fairly well, but is not 

 bright in color nor very active when on the hook. In lieu of better bait it does 

 fairly well for the smaller game fishes.
