boss. The lateral condyle is equally high, but it is narrower, and 

 from it a well-marked fairly sharply rounded ridge passes on to the 

 hinder face of the bone. The anterior face of the bone is flat in its 

 lower half. The lower articular surface has a maximum width of 

 175 mm., and a height of 105 mm. 



The femur differs from that of P. stormbergensis in the position of 

 the 4th trochanter and in the greater thickness of the caput femoris. 



Tibia. The right tibia (Cat. No. 3341) is a complete bone, whose 

 total length is 440 mm. The proximal surface has a length of 175 mm.

from the median condyle to the anterior point, and a maximum 

 breadth of 99 mm. The surface is higher on the inner border than 

 on the outer. At the distal end the anterior process stands at least 

 50 mm. higher than the narrower, prominent posterior rnalleolus. 

 The anterior border of the distal end is 111 mm. long, the inner 

 border 83 mm., and the posterior border (parallel to the anterior) 

 76 mm. long. 



This bone is shorter than the tibia of Gryponyx africanus, but is 

 much more robust. The head is the same length but wider. The 

 distal end is very much stouter.
