Comment

Recognized as a distinct species, rather than a subspecies of Bufo hemiophrys by Packard, 1971, J. Herpetol., 5: 191-193, and most recently by Smith, Chiszar, Collins, and Van Breukelen, 1998, Contemp. Herpetol., 1998: 1. Nevertheless, Cook, 1983, Publ. Nat. Sci. Natl. Mus. Canada, 3, considered Bufo baxteri to be undiagnosable within the context of geographic variation within Bufo hemiophrys (as Bufo americanus hemiophrys) and this has not been adequately addressed by subsequent authors (DRF). See map, description of geographic range and habitat, and conservation status (as Bufo baxteri) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 137.
