Etymology: Etheostoma: Greek, etheo = to strain + Greek, stoma = mouth; Rafinesque said "various mouths", but Jordan and Evermann suggest the name might have been intended as "Heterostoma (Ref. 45335); baileyi: Named after Reeve M. Bailey, contributor to the knowledge of North American fishes (Ref. 10294).
