for comparison, it is still more impossible to make such an identification with regard 

 to tlie shape of the horns. Blaine describes 1 the horns of R. redunca ugandce (or as he 

 terms it Cervicapra bohor ugandce) as »short and stout, withoiit a prononnced hook 

 forward ät ends». The horns of both specimens collected by Capt. Arrhenius must on 

 the contrary be said to be very strongly hooked forwards, and with the tips much turiied 

 inwards. This is of interest because Blaine's race R. r. ugandce is typical from Nkole, 

 Uganda, and it could therefore from a geographical point of view have been expected 

 to find this Reedbuck at Rutshuru rather than the more eastern R. r. wardi. 



Two young Reedbuck calves in the collection from Rutshuru 8 / 12 1913 belong 

 without donbt to the same race.

A young $, Rutshuru, 7 / 8 1913; 

 a male skull without skin (ef. fig. 8). 



The colour of these specimens agree on the whole with Matschie's description but 

 it is, of course, as always in Bushbucks somewhat variable. The smaller and somevvhat 

 youngcr, but nevertheless adult buck (with permanent dentition in place) has less white 

 markings and no transverse stripes. In the larger 4 — 5 such may be traced. The same 

 has also a white mesial stripe along the blackish chest.

The measurements of the male skull appear to be a little greater than those recorded 

 by Matschie, 2 but with regard to the female the opposite is the case. 



Okapia johnstoni öclater. 



A young male and a young female both with milk-dentition from Beni 1914. 



The male specimen is somewhat older so that the first molars in both jaws are 

 developed, in the female they are just cutting the gum, but m 1 is a little more developed 

 than ra 1 and its anterior lobe has already become somewhat blackened by the food.
