M. Transverse diameter of pelvis, including sacrum 1·171 Long diameter of ilium (from lower margin of the crest to sacral surface) ·440 Short diameter of ilium (from acetabulum to upper margin of crest) ·393 Length of acetabular border ·125 Length of ischium ·220 Width of ischium at tuberosity ·124 Length of pubis ·196 Greatest width of pubis ·061 Smallest width of pubis ·027 Long diameter of acetabulum ·139 Short diameter of acetabulum ·118 Long diameter of thyroid foramen ·094 _The Femur_ (Plate VIII., Fig. 4).---The femur is short, with a small oval head, strongly compressed fore-and-aft. It is less out of the axis of shaft than in _Proboscidea_, and has no pit for the ligamentum teres. The shaft is straight and simple, much compressed transversely at the proximal extremity, becoming sub-cylindrical below. The great trochanter is heavy, rugose, and strongly recurved; it is separated from the shaft by a wide and deep digital fossa. The second trochanter is a mere rudimental tuberosity. The condyles are nearly of an equal size, very convex, and are divided by a deep popliteal groove. The condylar tuberosities are low, the internal sends obliquely a ridge three inches long, up and across the axis of the shaft at an angle of 45°, that forms the upper boundary of the popliteal space. The front part of the trochlear faces for the patella are gone in our specimen. _Measurements of Femur._ M. Greatest distal diameter across condyles ·178 Length of condyles ·079 Transverse diameter of shaft six inches above distal end ·121 _The Tibia_ (Plate VIII., Fig. 2).--The tibia is short, straight, and simple, slender in the middle, but much expanded at the extremities. The proximal end is especially massive, with deeply concave articular faces; the internal cotylus is the larger, and has its greatest diameter fore-and-aft, directly at right angles to the greatest diameter of the external.
