=Ox.=—The shallowness of the acetabulum is compensated by the greater
size of the marginal cartilage. The head of the femur has a smaller
radius of curvature than that of the horse, and the articular surface
extends a considerable distance outward on the upper surface of the
neck. The round ligament is entirely intraarticular; it is small, and
sometimes absent. The pubo-femoral or accessory ligament is absent.
There are no important differences in the other animals.
