whether of the fore or hind foot cannot be said, as it was mis- 

 placed. Its measurements are as follows : 



Length 36 mm. 



Width at extremities 11, 12 



Least width of shaft 9 



Pelvic Girdle and Extremity. 



The three pelvic bones of the right side are lying with their 

 articular surfaces nearly contiguous, the upper end of the ilium 

 in apposition with the end of the transverse process of the 

 sacrum. On the left side, the ischium and a part of the ilium, 

 also in position are alone represented. Unfortunately of those 

 of the right side the outer end of the ilium and a part of the 

 anterior border of the pubis have been lost. The ilium is an 

 irregular rod of bone, stout and not very brpad with a pointed 

 sacral extremity. Its anterior border is deeply concave, smooth 

 and rounded, and not very thick. Its posterior border is dilated 

 into a thinner expansion below, which is turned outward. 

 Near the extremity, however, the bone again forms one plane 

 and is moderately thick. 



Greatest width of ilium 35 mm. 



Width before the acetabular articulation 26 



On the inner margin near the tip, there is a slight roughen- 

 ing, lying in apposition to the tip of the transverse process of a 

 sacral vertebra. 



Ischium. 



The ischia have a smooth, paddle-shaped extremity, a long 

 tooth-like tuberosity, and a dilated articular extremity which 

 shows facets for the ilium and pubis. The symphysial end is 

 broad, nearly straight on its margin, with rounded angles, and 

 moderately thick. The tuberosity, which is situated about the 

 middle of the bone, is conical, pointed and curved toward the 

 acetabulum. 



Length 84 mm. 



Width of symphysial end 43 



Width of acetabular end 35 



Width of shaft on the proximal side of the tuberosity 21 



Length of tuberosity 25
