144 MOSTLY MAMMALS 



should have a division to itself, may admit of argument ; 

 but at any rate it has many peculiar animals, among which 

 are a number of antelopes. 



Lastly we have the Saharan sub-region, which contains a 

 comparatively limited fauna, passing by almost insensible 

 degrees into that of Northern Africa. 



In some respects, especially in its galagos, the fauna of 

 Africa presents a certain resemblance to that of Madagascar ; 

 but the connection between that island and the mainland 

 was evidently very remote, and must apparently have 

 taken place before the great incursion of antelopes, zebras, 

 rhinoceroses, monkeys, elephants, etc., from the north, as 

 none of these are found in the island. Madagascar, there- 

 fore, is best regarded as forming a zoological province by 

 itself 



Within the limits of a single article it is manifestly 

 impossible to give anything like an adequate sketch of the 

 fauna of such an extensive area, but such points as have 

 been noticed serve to show in some faint degree its richness 

 in peculiar forms of animal life. 



It may be added that North-Eastern Africa has an extinct 

 mammalian fauna of its own, which seems to include the 

 ancestors of the elephant tribe.
