Journal of Herpetology 5(1-2):23-30 ABSTRACT - The finding of a partially complete specimen of the semi-box turtle, genus Emydoidea, from early Yarmouthian (second) interglacial deposits in Seward Co., Kansas, has prompted a reexamination of Emys twentei Taylor. Comparisons of the type-specimen with additional fossil material dating from the late Pliocene of Kansas and with Recent skeletons, indicate that all should be referred to Emydoidea blandingi (Holbrook). The fossil and modern distributions of E. blandingi are reviewed, including archaeologica
