Excerpt from Palaeontographical Society, 1856, Vol. 10: British Fossil Echinodermata, Part Second, the Diademadae, Echinidae, Saleniadae, and Echinoconidae; Fossil Malacostracous Crustacea of Great Britain, Part I., Crustacea of the London Clay; British Permian Brachiopoda, Part IV
The subject of the present description is the most complete specimen of fossil fresh-water Tortoise (emys) which has hitherto come under my observation. It was obtained, like the Emys Delabecfiii, Bell, which it most resembles, from the Eocene clay of Sheppey Island, and forms part of the large and instructive collection of Sheppey fossils belonging to J. S. Bowerbank, Esq., f.r.s. It consists of both carapace (t. XXVIII A), and plastron (t. XXVIII B), giving the natural curves, depth, and periphery of the portable abode of the animal. Every constituent bone of the com plex roof of this abode is preserved, and the impressions of every horny scute can be traced, uninterruptedly, upon its uninjured surface. The ﬂoor or plastron is, unfortu nately, not so entire, but its margins are unbroken, exhibiting the characteristic contour.
