Bufo cognatus Say In James, 1822, Account Exped. Pittsburgh-Rocky Mts., 1: 55 (Philadelphia edition). Holotype: Originally in "Philadelphia Museum" (which is not ANSP—DRF), according to the original; apparently destroyed according to Kellogg, 1932, Bull. U.S. Natl. Mus., 160: 43, who discussed the type. Type locality: "The alluvial margins of the [Arkansas] river," Prowers County, Colorado, USA.
