The Pubis and Ischium of the left(?) side are partly 

 preserved. They He, however, at right angles to the 

 bedding, so that only their articular ends are really visible. 



The visible part of the pubis shows the usual two 

 facets ; the posterior for the ischium 6"5 cms. wide and 45 

 cms. long, and the anterior 10 cms. long for the aceta- 

 bulum. 



Not actually united with this fragment but stretching 

 away in front of it is a bone seen in section 15 cms. long 

 and I cm. wide. This is probably the anterior plate of 

 the pubis. 



The Ischium shews its outer border, which is 15 cms. 

 long. The bone is so injured as to be quite indescribable.

The two femora are preserved. They are 35'5 cms. 

 long, 17 cms. wide distally, 9"5 cms. across at 15 cms. 

 from the distal end, and 9*5 cms. across the head. 



Both borders are concave, the posterior somewhat 

 more so than the anterior. The distal end is rounded, 

 and the head is a knob bearing a large trochanter some 

 5 cms. wide and projecting 3 cms. from the general level 

 of the shaft. 



The posterior surface of the bone is much roughened 

 from the middle of the shaft to the proximal end. 



Unless one of the bones purporting to belong to the 

 fore-arm is a tibia, no other bone of the hind limb is 

 preserved.
