Note. — This species is congeneric with the Moxostoma oblongum of authors, 

 but that name {Moxostoma) was first applied to a species of Ptychostomus. 

 Moxostoma then, if used at all, must supersede Ptychostomus. For the genus 

 of which CypHnus oblongus of Mitchill is the type, I would propose the name 

 of Erimyzon, a free translation of the vernacular name of Chub-sucker, by 

 which the species are sometimes known.
