Malaclemmys littoralis. The figures represent the same individual, an adult male 5 inches long, from Rockport, Tex. The tip of the tail has been injured.
From Holbrook, North American Herpetology, circa 1842 (public domain). This is a modified version of a plate from this work at the Biodiversity Heritage Library. I cropped and cleaned up the image quite a bit--removing the yellow cast and enhancing contrast and color a little. More of these images are posted on Wikimedia Commons, and I will be adding more as time allows.
