that of R. stonei, geographically its nearest neighbor, in its strik- 

 ingly small size, the mastoid breadth being 128 mm. in the former 

 and 158 mm. in the latter, with all that this implies in respect 

 to the general size. Notwithstanding this, the nasal bones are as 

 long in R. granti as in R. stonei, while the relative length of the inter- 

 maxillaries is greatly reduced in R. granti, giving very different pro- 

 portions to the parts that enter into the rostral portion of the skull. 

 The antlers in the two forms are also strikingly different, as regards 

 size and weight, and especially in the form of the brow antlers. As 

 regards cranial characters no comparison is necessary with R. montanus 

 or with any of the woodland forms.
