tuberosity, which is enormous ; while on the posterior face is 

 a deep fossa just below the head. The distal end of the 

 shaft is remarkably small, with two concave faces the inter- 

 nal the smallest with a low oblique ridge dividing them. 

 There is a prominent malleolus. 



The fibula (which is a distinct bone) has a small proximal 

 end, and expands slightly below, with a large external mal- 

 leolus.

The pelvis is described from the right and left ilia, which 

 are broken as they expand towards the crest ; the acetabulum 

 is fragmentary, but all the parts remain. The ischium and 

 pubis are only represented by fragments. As figured in 

 Plate V., the acetabulum is restored from a somewhat smaller 

 specimen. The most striking feature of the ilium is the long 

 and somewhat constricted neck. The acetabular border is 

 long and curved forward, thinning gradually as it approaches 

 the crest ; and marked on the iliac surface, near the acetabu- 

 lum, by a slight rugosity for the rectus muscle. 



The ischial border, while less arched, is probably longer ; 

 and the sacral surface, distinctly defined, indicates that the 

 rounded upper border of the ilium rarely reached above the 

 sacral spines. There is a deep groove between the ischial 

 and pubic borders, the latter disappearing about half way up 

 the iliac surface. The gtuteal surface near the acetabulum 

 is much depressed ; aboveit expands into a broad, flat, thin 

 plate. 



The ischium has a stout neck and thick expansion below ; 

 the upper border is very heavy. From what remains of the 

 ischium and pubis we can infer a large elliptical obturator 

 foramen, a short pubic symphysis, a narrow and rather 

 slight pubis, with a small nearly cylindrical neck. The 

 acetabulum is deep, with a thick well-raised border, and a 

 large, oblong, and very deep pit for the ligamentum teres.
