As to the anatomic features of the Diprothotno skull, Professor 

 Ameghino advances in substance the following: 



The skull was of small size, below the mean of human crania. Its 

 capacity could not have exceeded 1,100 c.c, its greatest length 17 cm., 

 and its greatest breadth 11.8 cm. 



The skull possesses a very low vault ; its front is so low that it sur- 

 passes in this feature the Neanderthal cranium. 



The skull was narrow, with the parieties almost parallel and with 

 a contour like that in the Ardopitheci; its greatest lateral diameter 

 did not fall in the region of the parietals as usual but on the frontal; 

 it was highly dolichocephalic, its breadth-length index being about 69. 



The frontal is very long and narrow, as in some of the lower Pri- 

 mates.
