Palaeoscincus costatus , Leidy. 1857. Proc. Acad. Nat. Sci. Philadcl., vol. viii, p. 72, and 1860, Trans. Amer. Philos. Soc. Extinct Vertebrata from the Judith river and Great Lignite formations of Nebraska, p. 146, pl. 9, figs. 49-52. In the collections are a few teeth that cannot be distinguished from the one figured by Leidy in the latter of the above two publications. Of these, an average speeimen is of the same size as the type and has the same number of serrations. As the erowns of some are worn the exact number of serrations that the tooth had originally cannot always be ascertained. Their sides are smooth. They seem to vary little in form but are proportionately thicker, near the base of the crown, than the type.
