Abstract

Geographic variation and distribution of the five forms of the long-tailed group of the snake genus Arizona are discussed. The recognition of a new form of Arizona elegans in northeastern Mexico necessitates a nomenclatural change for the populations in Texas and Northeastern Mexico. The validity of the subspecies blanchardi Klauber is established. Additional specimens have broadened the known variational and distributional pattern of A. e. expolita Klauber.
