in their place even a slight convexity. The lower part of the face 

 was prognathic, though evidently not excessively so. The dental 

 arches regrettably show extensive effects of a suppurative process, as 

 the result of which all but one or two of the teeth in the two jaws 

 have been lost, and the height of the alveolar processes was much 

 reduced by absorption. x\ll that can be determined is that the sub- 

 nasal portion of the upper jaw was quite high, and that the palate 

 was enormous.

The lower jaw is large, stout, chinless — though not sloping back- 

 ward at the symphisis, and otherwise primitive. It was doubtless 

 high, but the reduction of the alveolar process through pyorrhoea 

 and absorption does not permit a definite appreciation of this 

 character. 



Although only two badly worn premolars remain in the two jaws, 

 it can nevertheless be clearly seen from the size of their roots, from 

 the alveoli and from the size of the dental arches, that the teeth in 

 this skull must have been very large.
