THE TAXONOMIC STATUS OF THE WYOMING TOAD, BUFO BAXTERI PORTER
The population of toads in southeastern Wyoming named Bufo hemiophrys baxteri by Porter in 1968 is presumed to be extinct in nature, except perhaps for released, captive-bred specimens. It is sufficiently distinct in several respects, and sufficiently isolated geographically from its nearest rela- tive, B. h. hemiophrys, that it should be regarded as a distinct species, forming a superspecies group with B. hemiophrys
Geographic Variation in Toads of the debilis Group of Bufo
In 1938, Taylor (1938,513) for the first time pointed out the existence of two distinct forms of toads in the assemblage previously referred to Bufo debilis. These he designated as the species Bufo insidior Girard and Bufo debilis Girard. Since then much confusion has reigned, especially with respect to the range and status of the southeasterly form regarded as B. debilis
