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); swaini: Named after an active ichthyologist in the late 1800s, J. S. Swain (Ref. 10294).
Eponymy: Joseph Swain (1857–1927) was Professor of Mathematics and Biology at Indiana University (1883–1891) and a student of the author, David Starr Jordan, whom he followed (1891) to Stanford University and taught there as a professor of mathematics. (Ref. 128868), visit book page.
