an average specimen. In the »Book of Antelopes* the basal length of the skull of 

 this species is stated to be »14 inches* viz. 355 mm. and the greatest breadth to 

 5,2 viz. 131 mm. 



The behaviour of the Kongonis, how they have their sentinels standing on 

 termite hills and so on, has been repeatedly described. They are always wary and 

 sometimes very shy, but show at the same time a certain amount of curiosity. It 

 has been much spoken about the tenacity of life of this Hartebeest. If hit in the 

 right place I think, however, that they succumb as quickly for the bullet from a 

 modern rifle as any other antelope of that size. 



The Kongonis look sometimes more yellowish sometimes more reddish, but it 

 may depend upon the light. 



The specimens which I shot on the plains near Nairobi were infested with ticks 

 of the species Rhipicephalus pulchellus.

Mr. W. N. Mo MiLLAN of Juja farm kindly granted a fine bull Wildebeest to 

 be shot for the collections ^*/i 1911. There was quite a number of this species on 

 the plains belonging to his farm, but on our way further north we did not see any 

 more so that I suppose that Tana river is the northern boundary line of this species 

 east of Kenia. 



The habits and behaviour of this animal has been repeatedly described, and I 

 have nothing of value to add. It is strange to see how big and entirely black this 

 Gnu looks at some distance. When they run with lowered heads they remind in a 

 very striking manner of Bisons in spite of the in reality great difference in size. 



The specimen shot was greatly infested with ticks chiefly Rhipicephalus pul- 

 chellus. 



The dimensions of this skull agrees closely with the corresponding ones of the 

 typical skuU viz. 



Basicranial length 398 mm. 



Greatest breadth of skull 182 » 



Distance from orbit to tip of premaxillary 295 »

Harvey's Duiker has been recorded from Dar es Salaam, Tanga, the KiUmanjaro 

 district, and Southern Somaliland. It could then be expected that the red Forest- 

 Duiker of the Kenia district would prove to belong to this species. Since I had 

 succeeded in obtaining a specimen myself I found that there appears to be some
