BONES OF THE PELVIC LIMB 



153 



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 ifie 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 distal 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.
