E. LÖNNBERG, ON THE HARNESSED ANTELOPES. 11 



as it seems. the races with well-haired necks live in localities 

 situated higher above the sea level t han those in which the 

 others are at home. It is therefore siiitable to make a com- 

 parison between the locahties within the Cameroon district 

 in which the two races described above hve. All the speci- 

 mens of T. s. knutsoni ha ve been shot on the Cameroon Moun- 

 tain at 3Iann*s Spring which is situated about 7,500 teet 

 above the sea and surrounded by higher mountains. The 

 chmate here and at Cape Debundscha. near the sea. where 

 the other race hves. is quite different. While the lowest tem- 

 perature observed in tlie latter place during many years never 

 has been below + 18^ C. it of t en falls to + 12' C. at Mann's 

 Spring and Mr. Waldau has even observed + 6" C. Higher 

 up it is still less. of course. This means a good deal in a 

 tropical chmate. and serves perfectly as an explanation of the 

 better development of the tur in T. .^. knutson i. The forest 

 there consists of rather sparsely set, moss-covered trees. not 

 interwoven by lianas as the tropical forest of the lowland. 

 but there is a rich undergrowth of herbs and bushes in which 

 the Bushbucks conceal themselves. Here and there are open 

 grass covered plains on which the Bushbucks come out to 

 feed as already alluded to above. Also in the lowland the 

 Bushbucks do not live in the unbroken forest. but prefer t lie 

 edge of the same, near open, or even cultivated places. and 

 often frequent the farms. They live singly and ]Mr. Waldau 

 has only once seen two together. When the v get sea red they 

 ha ve a kind of coughing or barking sound >^hu luiv> wbicli 

 miglit be mistaken as coming from dögs. Their eye-sight 

 appears to be rather weak. Their hearing is probably good 

 to judge from their large ears. but a shot fired at a Bush- 

 buck and missing it does not always scare it away if it has 

 not seen or got the scent of its foe. It may therefore some- 

 timés happen that several shots can be fired wi.thout the 

 animal seeming to lieed them. 



When the Bushbuck is scared and runs. or rather bounds 

 away in big jiunps. it hfts its tail, and the white of the 

 same tlien becomes verv conspicuous. in the same way as the 

 Avhite tail of a rabbit. The lifted tail forms then in the 

 Bushbuck such a signal-» or »recognition-mark>. as it has 

 been called. and may be compared. not only with the rabbit-
