. Bulletin of the Museum of Comparative Zoology at Harvard College. Zoology. WOOD: FLORIDA MIOCENE RHINOCEROSES 381 Appendicular skeleton A fair number of limb elements are preserved and show that the legs were long and slender. This impression of length characterizes the scapula, No. 7447, the ulna, No. 7448, metacar- pal III, No. 7449, the femur, No. 7450, the fibula, No. 7451, and metatarsal IV, No. 7452. The scapula is like that of D. cooki with some similarity to Subhyracodon. The only carpals are a left lunar, No. 7453 and a right pisiform, No. 7454, both resembling D. cooki, with the dif- ferences that the lunar is stouter and the pisiform has less neck. Right metacarpal III, No. 7449, resembles D. cooki, but is considerably larger. The bone is crushed but it is clearly longer and stouter. A left metacarpal IV, No. 7455, agrees closely with D. cooki, but is a shorter bone. Comparison with the same bone in Floridaceras is striking; the metacarpal IV of D. barbouri is 72 per cent as long, but only half of any transverse measurement. A number of phalanges are similar to D. cooki, but are a little stouter and more Figure 2. Diceratherium barbouri. No. 7456, left half of pelvis. A, dorsolateral; B, lateral. X 1/4. Enough of the pelvis and hind limb is present to make further comparisons with D. cooki. The pelvis, 7456, is too frag- mentary for reliable measurement: what there is of it is small and delicate (Fig. 2).
