digits, P. brucei in Nyasa is distinguished from P. briicei elsewhere, 

 as just mentioned, by its white ears, pure white belly, and white 

 digits, each species when meeting its congener having, as it were, 

 emphasized its own distinguishing characters in order to be unlike 

 the other. For P. brucei, wherever found, is already characterized 

 by its pale colour generally, whitish head, and white or pale 

 yellow dorsal spots, while P. capensis, of which P. johnstoni may be 

 looked upon as a modification, has a generally dark colour and a 

 black dorsal spot. 



Thus there seems to be between the two a sort of mutual 

 "repulsion" in their characters, the exact converse of the better 

 known " mimicry." Its object would very probably be that of 

 furnishing the individuals of each species with " recognition 

 marks " by which to kuow comrades from rivals.
