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); fonticola: From the Greek etheo=to strain and stoma=mouth; fonticola=fountain dweller (Ref. 79012).
