average for the males being 104.1; for the females, 99.7; and 

 for both combined, 101.9. 



It naturally follows that the crania are markedly phaeno- 

 zygous, the bizygomatic diameter averaging 18.4 mm. longer 

 than the maximum frontal (14.7 mm. for males, and 22.1 mm. 

 for females) and even 1.7 mm. longer than the greatest breadth 

 of the skull: 



Prognathism is a prominent feature in the entire series, 

 the average index, Gnathic 1 of Flower, being 106.7 (range 102 

 to 1 1 1.6).
