158 A NATURALIST IN THE TRANSVAAL. 



Three of the crania are those of adults, and three from young 

 persons, the probable ages of the latter being about 12, 13, and 

 14 years. 



All the crania are of the true dolichocephalic type, are 

 platyrhine, except the one numbered 1299 E, and mesognathous 

 except 1299 F. 



The following gives the measurements of the crania and 

 chief peculiarities. 



1299 A. Metopic (persistent mid-frontal suture), showing the 

 outward bulging of the frontal region of the temporal 

 fossa commonly present in this condition, also a shallow 

 depression immediately posterior and parallel to the coronal 

 suture.
