Some Instances of Colour-Protection in Mammals 295 
of the one obtaining in animals like the kiang and the gazelles, where protection 1s 
evidently the object. The nilgai is generally met with in open country or thin scrub, 
while the wapiti may be found either in forest or on open hillsides. Considering that 
other deer show protective coloration, it is scarcely likely that the wapiti is an exception; 
nor does it seem probable that the nilgai does not need protection by this means. 
In what way (f at all) such a peculiar type of coloration harmonises with the surround- 
ings of these animals awaits explanation.

The foregoing are only a few out of many striking instances of the harmony existing 
between the colourme and the environment of mammals. Did space permit, other 
difficulties connected with the subject might advantageously have been discussed. But 
I have already largely exceeded editorial limits, and must therefore bring my remarks 
to a somewhat abrupt ending.
