The femur, humerus, radius, and pectoral girdle have been completely preserved, and the pelvis can be restored except for the distal portions of the pubis and ischium. Partial tibiae, fibulae, and ulnae have been found, as well as sacral ribs, some caudal vertebrae, and two cervical verte- brae. Xot a scrap of skull or jaw has turned up. These elements compare well with their counterparts in the Painted Turtle, Chrysemys picta. The ratios of limb bone lengths â to plastron lengths are similar in both, as are the basic shapes. These facts plus the relative delicateness of the limb bones show- that the legs of Echmatemys septaria callopyge were no better developed than are those of the modern Painted Turtle. One of the cervical vertebrae is most probably a fourth; it appears to be narrower anteriorly than the fourth in Chrysemys, but otherwise resembles it. The other cervical is a characteristic eighth. Hay (1908, p. 297) illustrated a series of limb and girdle bones presumed to pertain to Echmatemys. The similarities be- tween these and the E. s. callopyge material are obvious, and the differences are minor. In view of the paucity of such fossils, 1 see no reason for a detailed comparison at this Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Harvard University.
