THE AFRICAN HUNTING DOG. 405 
the representative of a rather common intermediate type of 
colour-pattern, in which there is a fair amount of white shown 
on the body and limbs, and the tail is about half black and 
half white. 
The northern part of the Sabi Reserve is covered with dense 
thorn bush, and in the neighourhood of the large Olifants River 
is rather stony. Then comes a stretch of savanna country some 
70 miles in width, after which, in the neighbourhood of the 
Sabi River, the country is the same as that first described. In 
both the first and last the game is of similar character, mainly 
Impala and smaller antelopes, with large numbers of Reedbuck 
in certain localities. Im the savanna country are found mainly 
Waterbuck and the plain-dwelling antelopes. Thus the Hunting 
Dogs in these areas have to adapt themselves to slightly different 
conditions of hunting, and while there is no doubt that in the 
south and north they find that their prey comes comparatively 
easily, in the centre they have to work hard to secure it. 
So far as my observations have gone it seems pretty certain 
that the savanna packs stick in the main to their own country, 
though they occasionally raid north and south into the bush. 
The same may be said inversely of the bush packs, north and 
south. One might, perhaps, recognise some general similarity of 
type between the bush packs of the north and south respectively, 
in which, on the whole, the individuals are larger than are those 
of the savanna country, and agree in being less extreme in 
colour-patterns of their coats. But these animals of the north 
and south probably never came into direct contact with one 
another, whereas the intermediate packs touch each of them. 
Instead, then, of having a gradual transition of type from north 
to south, we find that the extremes have certain affinities in 
common, mainly as regards size, and this may perhaps be 
accounted for by the relative amount of food available for the 
young animals. This is doubtless the foundation for the native 
belief that there are two species of Hunting Dogs within the 
same area, one larger than the other. 
As regards colour-types, however, all agree in their individual 
dissimilarities. 
The following are a few measurements, taken at various times; 
of full grown animals from the Portuguese boundary of the 
eastern Transvaal.
