Cranial and Dental Characters. 



The sagittal ridge may be very strongly marked posteriorly or be 

 obsolete. There is generally a raised flattened tract in front of it, the 

 lateral margins of which have a somewhat lyrate outline. 



The relative length of the postorbital processes varies in different 

 individuals, as also does their curvature. 



The dentition is remarkable for the very small size of the fourth upper 

 premolar compared with the combined lengths of the first two upper 

 molars, its proportional length to theirs being, on an average, as 100 to 

 166, three specimens being examined.
