Class Reptilia
Order Squamata
Suborder Sauria
Family Anguidae
The Anguidae include three genera in North America. Only one species is represented as a fossil in our region, however, and that may be Holocene rather than Pleistocene.


Synonyms. Gerrhonotus kingii.
Van Devender and Worthington (1977) reported the Madrean Alligator Lizard as a fossil from Howell's Ridge Cave and also as occurring at present in a nearby wash. Most modern occurrences, however, were said to be in somewhat more mesic, montane situations.
