Fusion of the three bones occurs at seven to ten months. The pelvic inlet is elliptical ami is more oblique than in the horse. In a cow Median Wing of crest uf Tuber sacrum sacrum sacrale.

The anterior end of the symphysis lies in a transverse plane through the junction of the third and fourth sacral segments. The dorsal wall or roof is concave in both directions. The ventral wall or floor is deeply concave, particularly in the transverse direction. The cavity is narrower and its axis is inclined .strongly upward in the posterior part. The distance between the acetabuluna and the tul3er coxae is only a little (ca. 3 to 4 cm.) more than the distance between the former and the tuber ischii. The femur has a relatively small shaft, which is cylindrical in its middle, pris- matic distally. The trochanter minor has the form of a rough tuberosity, and is situated higher up than in the horse and encroaches on the posterior surface. The trochanteric ridge (Crista intertrochanterica posterior) connects it with the tro-.
