LONNBERG, MAMMALS. 47 



top of the muzzle. A whitish band from the upper eyelid to the side of the muzzle. 

 A black spot above the eye extends over the eye as a dark band below the just 

 mentioned whitish one. Behind the eye, above and below, this blackish band is bor- 

 dered by a large whitish patch. The pattern of the adult is thus present, although 

 the colours are not so bright. 



In this respect this species differs from Gazella tkomsoni the kids of which have 

 the same colour as the adult. 



The spreading of the horns of the adult varies a great deal independently of 

 age. In one of the oldest bucks the distance between the tips is only 25 cm., in 

 another 35 cm., and in a third 43 cm. 



For the knowledge about the propagation and growth of this species the follow- 

 ing notes may be of some value: the 29th of Dec. an uterine foetus was found in 

 a female, a quite small calf was taken at Same in Usambara at the end of June, 

 and the first days of Oct. young specimens were found with the horns 10 cm. in 

 length and curved forward. 



The Grant Gazelle is the most common antelope in this district and it is the 

 most beautiful representative of the steppe fauna. It lives always in smaller or 

 greater herds - - sometimes containing hundreds of heads - - often in company with 

 Thomson Gazelles as well as with Kongoni antelopes, Gnus and Zebras at Ngare 

 nairobi, Ngare na nyuki (PI. IV, fig. 1) and Kiraragua, but at other places as well. 

 No antelopes of any kind were, however, seen in the district at the western and 

 northwestern side of the Meru mountain, although wide grass steppes extended there. 

 On the northwestern side of Kilimandjaro again they were very common and not 

 shy as they seldom were disturbed by men there. The herds of Gazelles consisted 

 there only of the present species, seldom any Thomson Gazelles were seen among 

 them. 



The 27th of March a great herd of Gazelles was seen on the steppe at 

 Ngare nairobi. It consisted only of half grown animals and their mothers. In 

 their sandy yellowish coat they have a great resemblance to the often yellowish 

 surroundings and in a certain light and at some distance they sometimes might 

 become unnoticed if they did not show against the horizon. As worthy guards of 

 the herd the old bucks are least shy and they are often seen wandering by them- 

 selves at some distance from the others. They are the last to run away when some 

 danger threatens, while the does and still more the kids in a great hurry speed off 

 the latter with elastic leaps and tail erect, bounding like rubber balls scare the whole 

 herd to flight through their liveliness. The bucks swing their tails uneasily and 

 walk leisurely away, heroically covering the retreat. Then at once when the others 

 have got aAvay the bucks speed away, but stop perhaps soon again and resume their 

 walk. Wounded bucks are not readily abandoned by the herd. The animals stop 

 often in their flight and look back at their leader; a certain uneasiness appears to 

 have got hold of them all (SJOSTEDT). 



The Gazelles that live in the acacia forests eat leaves, pods and pease of the 

 acacias as an examination of their ventricle proves.*
