. The alligator and its allies. Alligators. The Skeleton of a division into two articular surfaces. The ventral side of the femur near the proximal end shows a fairly distinct trochantal ridge. The shin or crus is made up of two well-developed bones, the tibia (t) and fib- ula (fb), the former being somewhat longer and con- siderably thicker than the latter. The tibia consists of a cylindrical shaft with en- largements of about equal size at the ends. The proximal end forms most of the knee joint, the distal end articulates with a tarsal element said by Reynolds to represent the fused astragal

The proximal end forms most of the knee joint, the distal end articulates with a tarsal element said by Reynolds to represent the fused astragalus and cen- trale, by Wiedersheim called the astragalus, and said to represent the united tibiale, interme- dium, and centrale (tb, tb'). The fibula articulates by a small enlargement at its proximal end with the femur, and by an enlarge- ment of about equal size, at its distal end, with the fibulare or calcaneum (ca), and with a small facet on the above-mentioned tibiale-centrale -cl FIG. 29.
