. Catalogue of the fossil Reptilia and Amphibia in the British Museum (Natural history) ... By Richard Lydekker ... Reptiles, Fossil; Amphibians, Fossil. 156 CHELONIA. Tropidemys valanginensis (Pictetl) indicates the survival of the genus to the Neocomian. In. a species from the Kimeridgian of Hanover, referred to this genus and figured by Portis2, it appears that there was a median line of small intervertebral shields. Pig. Tropidemys (cf.) langi.—The second neural bone ; from the Kimeridge Clay of Dorsetshire. J. Tropidemys langi, Eiitimeyer3. The type species. Carapace very broad and flat anteriorly. Ver- tebral shields with highly curved anterior and posterior borders. The following specimens are provisionally referred to this species, but there is no evidence to show that they may not be referable to T. expansa, Eiit. 4, or T. gibba, Hab. Europe (Switzerland, and ? England). 44178 b. The second neural bone of the carapace; from the Kime- (Fig.) ridge Clay (Upper Jurassic) of Weymouth, Dorsetshire. This specimen (fig. 38) indicates a smaller individual than the type specimen, of which the 3rd to the 6th neurals are figured by Eiitimeyer in the ; N. Denkschr. schw. Ges. Nat.' vol. xxv. art. 2, pi. vii. fig. 2; it agrees in contour with the 2nd neural of T. expansa figured in pi. ix. fig. 3 of the same. Purchased, 1873. 45920. The first three costals of the right side of a young carapace, not improbably specifically identical with the preceding specimen; from the Kimeridge Clay of Weymouth. The subequal facets for the two lateral surfaces of both the 2nd and 3rd neurals are distinctly shown. The specimen accords well with the larger example of T. expansa figured by Eiitimeyer, op. cit. pi. ix. fig, 3. The contour of por- tions of the first three vertebral shields is preserved. Purchased, 1874. 1 Materiaux pour la Paleontologie Suisse, ser. 2.—Terrain Cretacede Croix, p. 30, pi. i. (1858-60). 2 Palacontographica, vol. xxv. art. 3, pi. xv. (1878
