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. Mc MILLAN of Juja farm kindly granted a fine bull Wildebeest to 
be shot for the collections 4 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.

Harvey's Duiker has been recorded from Dar es Salaam, Tanga, the Kilimanjaro 
district, and Southern Somaliland. Tt could then be expected that the red Forest- 
Duiker of the Kenia district would prove to belong to this species. MWSince I had 
succeeded in obtaining a specimen myself I found that there appears to be some
