GEOGRAPHICAL DISTRIBUTION.

It will be apparent from the above tables that, while the 

 living Leinuroidea are confined to the Eastern Hemisphere, in 

 past times some genera were not only common to both Hemis- 

 pheres, but the Order was equally well, if not indeed better, 

 represented in the New, than in the Old, World. Among the 

 Anthropoidea, on the other hand, then, as now, none of the 

 genera were common to both Hemispheres; and a large 

 number of the genera, which then existed, were identical with 

 genera now hving, to a greater extent than among the 

 Leinuroidea. 



II. Tables to illustrate the distribution of the genera of 

 Primates in time, in the different Zoo-Geographical Regions 

 into which the World has been divided.
