Rh Carapace much depressed, oval, with a feeble median keel posteriorly; anterior border broadly emarginate. Nuchal shield very small, broader than long; vertebrals broader than long, as broad as the costals or a little narrower, much broader in the young, in which the posterior border of the carapace is distinctly serrated.

Front lobe of plastron squarish, posterior angularly emarginate; the width of the bridge contained four or five times in the length of the plastron; the longest plastral shields are the anals, femorals, and humerals; the shortest the gulars, which occupy, however, the whole width of the front border of the plastron; frequently a small intergular shield between the gulars and the humerals. Upper surface of head and temple with an undivided horny scute.
