Abstract
Turtles are reptiles in which the body is wide and short, and is enclosed in a shell composed of a dorsal shield, the carapace, and a ventral shield the plastron. The shell of three of the species is composed of large external, epidermal, horny plates. These latter consist, in the carapace, of the flattened ribs and the flattened trunk vertebrae which coalesce with overlying dermal bony plates, and are surrounded on the circumference of the shell by a series of marginal dermal bony plates; in the plastron they consist of exclusively dermal plates, there being no sternum. The carapace and the plastron are more or less firmly united by a wide bridge on each side.
