R. 504. Mass of matrix containing two entire skulls and the anterior 

 portion of a third one, together with imperfect limb-bones 

 and vertebras ; from the Orange Free State. The skulls 

 are rather larger than the preceding ones ; in the best 

 preserved example the orbits appear to have been enlarged 

 by fracture. The vertebras arc too imperfectly preserved 

 to admit of the determination of their characters.
