From the foregoing it will be observed that the Ethiopian Region 

 contains the largest number of genera of the Primates, viz. : twenty- 

 five, the Neotropical Region next with fourteen, then the Oriental 

 Region with nine, the Palaearctic Region three, and the Australian 

 Region with three. All the species of LEMUROIDEA excepting the 

 species of Daubentonia, Tarsius, Loris and Nycticebus, are natives 

 of the Ethiopian Region. Of the genera of the ANTHROPOIDEA 

 two are common to two of the Zoogeographical Regions, viz. : Pithe- 

 cus and Pygathrix which are represented by species in the eastern 

 portion of the Palaearctic Region and generally, (more particularly as 

 regards the first genus), in the Oriental Region, and one, Tarsius, has 

 species in both the Oriental and Australian Regions. All other genera 

 have their members confined to one Region only.
