The »Kongoni> as Coke’s Hartebeest usually is called in Brit. East Africa, is 
the commonest Antelope on the great plains along the Uganda railroad in the southern 
game reserve, and around Nairobi it is still common, although its numbers are dimi- 
nished where the country has been settled. At Juja farm Kongonis were abundant 
on the open plains. It does not appear to extend its distribution north of Tana river, 
at least not in the interior of the country. It was not seen on the acacia steppe 
south ef Guaso Nyiri, although its companion on the Athi plains, Grant’s Zebra, was 
common there. 
In the »Book of Antelopes» it is quoted from GrpGeE concerning this species: 
»The cows calve during the latter part of November and December» — -—- —. It 
is very possible that some of the cows calve at that time, and some calves which I 
saw in the beginning of April appeared to be a few mouths old, while calves seen 
from the train in the southern game reserve *‘/i2 1910 looked to be more than a 
month old. But Roosrvett’s observation’ on the Athi plains where he says that 
he found »new-born wildebeest and hartebeest calves, and others several months 
old» in the month of May is more in accordance with my own experience. I shot 
for scientific purpose two Kongoni cows the 11 of April and both those contained 
foetuses which were covered with hair and nearly full-grown. The majority of the 
cows appeared at that time te be in the last stages of gravidity. But as already 
mentioned there were also calves which probably had been borne some months earlier 
their number was, however, less than that of the gravid cows. I saw only once a 
Kongoni cow with twins.

As can be seen the measurements of this cow are larger than those of the bull 
which may depend upon the fact that the cow was unusually big, and the bull only
