VI. The Hind Limb. 



Of the pelvis, only the ilium is preserved, but this is very differ- 

 ent from the ilium of Tragulus ; the neck is much shorter, less 

 compressed, and more trihedral in shape ; the plate is broader, 

 more everted, and more suddenly expanded ; the crest above the 

 acetabulum is higher and thicker. What 

 is preserved of the pelvis, therefore, rather 

 resembles that of the true ruminants than 

 of the tragulines. 



The proximal end of the femur is also 

 very different from that of Tragulus ; the 

 neck is much longer and more constricted, 

 and the head relatively smaller ; the great 

 trochanter is higher and more massive, and 

 the bridge connecting this process with the 

 head is more constricted, the digital fossa 

 is much deeper, and the second trochanter 

 more massive and prominent. The shaft 

 appears to be rather more slender. The 

 distal end is very much like that of the 

 modern genus. The rotular trochlea is 

 broad and shallow, with margins of nearly 

 equal height ; it is very long vertically, and 

 but little arched antero-posteriorly. The 

 condyles have but a small fore and aft 

 diameter ; they are of nearly equal size 

 and quite widely separated. Above the 

 external condyle there is sometimes a pit, 

 sometimes a rugosity, for the plantaris 

 muscle. 



The patella is long, narrow, and pointed, 

 resembling that of Tragulus, except for the 

 much diminished thickness of its proximal 

 portion. 



The tibia is of about the same relative length as in the modern 

 type, but the cnemial crest is more prominent ; the outer con- 

 dyle projects considerably beyond the line of the shaft. The 

 astragalar surface is not very deeply grooved and the internal 

 malleolus of only moderate length. The fibula is completely
