The following table shows the approximate number of 

 genera of the West African Sub-region in each order and 

 their distribution : — 



Section VI. — The Cape Sub-region 



This Sub-region, when extended so as to include the 

 whole country as far north as Angola on the west, and up 

 to the Tana river on the east, is on the whole, after the 

 Malagasy, the most distinct of the four Sub-regions, since it 

 possesses nineteen endemic genera out of a total of ninety- 

 one. Furthermore, its area exhibits a greater range of 

 temperature and humidity than the other Sub-regions, for, 

 while in Natal and Mozambique tropical forest-conditions 

 prevail, giving the fauna a certain resemblance to that of 

 West Africa, in Cape Colony itself a temperate and fairly 

 dry climate is found. Again, in Namaqua-land, to the 

 north-west of Cape Colony, we meet with an open, dry, hot, 

 desert country, the conditions of which closely approximate 

 to those of the Saharan Sub-region. The distinctness of 

 this Sub-region, apart from the mammals, is strongly 

 marked by a very remarkable Flora, as well as by the 

 exclusive possession of many forms among the other orders 

 and classes of the animal kingdom. Among the Edentata,
