The lectotype of Boa carinata Schneider, 1801, has been rediscovered and is now ZMFK 35503, having been transferred in 1977 from the Göttingen Museum, its original location. Its type locality has not been reported previously, but is indicated as "Amboina" on a label with the lectotype. The specimen is redescribed and figured, and conforms with expectations for material from the vicinity of the type locality. A brief history of Schneider and of the syntypes of Boa carinata, now Candoia carinata, is reviewed.

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 relative, B. h. hemiophrys, that it should be regarded as a distinct species, forming a superspecies group with B. hemiophrys.
