Geoclemys

Geoclemys is a genus of turtle in the family Geoemydidae. The genus contains a single living species, the black pond turtle (Geoclemys hamiltonii). Two fossil species are also known from the Miocene of Japan: Geoclemys matuuraensis and Geoclemys yudaensis.

Etymology
The specific name, hamiltonii, is in honor of Francis Buchanan-Hamilton, who was a Scottish botanist and ichthyologist.
