VI. TJie Hind Limb. 



The hind leg is much longer and heavier than the fore leg in 

 all its parts. The disproportion is, however, by no means so 

 great as in Tragulus, but rather resembles the condition'found 

 in MoscJms. In the living animal the increased length of the 

 hind leg was compensated by the greater habitual flexure of 

 the knee and hock joints. 



The Pelvis is pecoran rather than traguline in character. 

 The ilium has a thin and compressed, but rather short and 

 deep, plate-like neck, which expands gradually into the large 

 and everted anterior portion. The outline of the anterior or 

 supra-iliac border is like that of Cerviis more than of Moschus
