About This Book
The paper compares diagnostic characters of two garter snake species in southern Kansas, detailing scale-row patterns, dorsal stripe edges, labial markings, and a postrictal crescent, and maps typical localities for each form. It notes overlapping ranges and a tendency for one species to exhibit traits of the other in the southwest. Examination of many specimens reveals occasional individuals with intermediate characters; one specimen is interpreted as a likely hybrid based on mixed stripe, labial, and postrictal features. Because both forms maintain distinct combinations of characters where sympatric, the author treats them as separate species while acknowledging limited hybridization and morphological convergence in marginal populations.
