chanter major. The third trochanter is absent. The supracondyloid fossa is 
shallow. The proximal extremity is very wide. The head is smaller than in the 
horse, and the articular surface extends considerably on the upper surface of the 
neck. The fovea capitis is a small depression on the middle of the head for the 
attachment of the round ligament. The neck is well defined except above. The 
trochanter major is very massive and is undivided; its lateral surface is very rough.

The trochanteric fossa is deep, but does not extend so far distally as in the horse. 
The distaf end presents no very striking differential features, but the ridges of the 
trochlea are less oblique than in the horse, and converge very slightly below. The 
proximal extremity unites with the shaft at about three and one-half years, the 
distal at three and one-half to four years. 
The tibia resembles that of the horse rather closely, but is somewhat shorter.
