362 Wonders of the Bird World 



South Africa than to those from the more adjacent lands 

 of Abyssinia and East Africa proper. 



VI. THE SOUTH AFRICAN SUB-REGION. 



When I first indicated this Sub-Region as a natural one, 

 I was incHned to regard its northern boundaries as the 

 Coanza river on the west, and the Zambesi river on the 

 east. I have, however, lately been forced to admit that 

 the Zambesi seems to form no natural boundary, and the 

 limits of the South African Sub-Region apparently reach 

 the line of 10° N. Lat. and may even extend to the vicinity 

 of the Victoria Nyanza, as such typical forms as Chera 

 progne (the Long-tailed Whydah Bird) and Pyromelana taha 

 (the Taha Weaver-Bird) have been found in the swamps 

 of Equatorial Africa. 



A. The Cape Province. 



This embraces a small area, and includes the Cape Colony 

 to the south of the Orange River and the Karroo. In the 

 latter arid district several peculiar genera and species of 

 Larks are found, and the Cape Province has many charac- 

 teristic species not found outside its limits. 



B. The Natalese Province. 



In the eastern districts of the Cape Colony the Fauna 

 is decidedly different, and shows a peculiar element of its 

 own. From the neighbourhood of Grahamstown and the 

 Peri Bush, near Kingwilliamstown, occur many represent- 

 ative species which extend their range through Natal and 

 the Eastern Transvaal to the Zambesi, or even to 

 Eastern Damara-land. In the latter district a more 

 desert aspect supervenes, and many widely-distributed 

 South African species here exhibit a paler colouration in 

 consequence.
