314 AFRICAN GAME ANIMALS 



at its entrance into Lake Rudolf, and by Donaldson Smith 

 from Lake Stephanie and the country east as far as the 

 Webi Shebeyli River. The southeastern and southern 

 limits of the race in the Tana district are not yet known. 

 Lydekker has given the racial name nigricans to a small 

 piece of body skin from the Kenia district bearing black 

 blotches separated by narrow, white reticulations, which 

 apparently came from an individual of this race. It is un- 

 fortunate that so well known a naturalist as Lydekker 

 should add to the burden of zoological nomenclature by at- 

 taching a scientific name to a mere fragment of skin of so 

 variable a mammal as a giraffe.

Range. — From the Uasin Gishu Plateau and Lake 

 Baringo northwestward over the highland and desert region 

 of Uganda to the latitude of Gondokoro; east probably as 

 far as the west shores of Lake Rudolf and west as far at 

 least as the east bank of the Nile; limits of range not 

 known. 



The Uganda race has frequently been designated the 

 five-horned giraffe, owing to the occasional development of 

 two small horns at the extreme hinder part of the head 

 behind and above the ears. These so-called fifth horns 

 are never more than mere rounded knobs an inch in height, 

 and are only to be found in some aged bulls. The presence 

 of a fifth pair of horns is not a peculiarity of the Uganda 

 giraffe, but is shared by the reticulated as well and appears 

 to be carried to a somewhat greater development in the 

 latter race. Bony excrescences of equal prominence to the 

 fifth horns also occur not infrequently above the orbits 

 and sometimes as adventitious knobs on the sides of the 

 main horns. In old age the skulls of the bulls produce a 

 great amount of dense bony tissue which greatly adds to
