to time been reported in the north, about the Portuguese 

 border. In Southern Rhodesia a few are still found 

 locally, but are, it is to be feared, being gradually exter- 

 minated, notably on the south-eastern border, where 

 Portuguese natives with guns are busy amongst them, 

 In Northern Rhodesia plenty still exist, and the same 

 thing might have been said of many districts of Portuguese 

 East Africa up to three or four years ago ; but the native 

 equipped with the arms of civilization is wearing their 

 number down with amazing rapidity in all but the most 

 remote localities. 



The species further ranges through Angola and German 

 and British East Africa as far as the Tana River. Thence 

 northwards it has not up to the present been met with 

 east of the Nile, and west of that river appears in the 

 form of another species, the Derby eland, which is dis- 

 tinguished by its very much larger horns and richer 

 markings. This fine species extends from the left bank 

 of the Bahr-el-Ghebel from Rejafon the south to at least 

 as far as the confluence of the Bahr-el-Ghazal on the 

 north, and westwards across the Sudan to Senegambia, 

 and is sometimes known as the giant eland. At present 

 no connecting link has been met with between it and 

 the form of the typical species found in East Africa, 

 but thence southwards there is a fairly even gradation 

 of type from an animal with a black back line, white 

 body stripes, dark knee bands, and a small frontal bush, 

 to one whole coloured with no indications of body 

 markings, and large tufts on the forehead and face. 



The white chevrons, or V-shaped markings, sometimes 

 quoted as being distinctive of certain local varieties, seem 

 to appear in individuals of all of them, while absent in 

 others. An old bull eland shot near Inhambane had a 

 pronounced white face chevron and no forehead tuft at
