The deer of the Eastern Hemisphere mostly belong tothe genus Cervus. The red-deer, C. elaphus, is found in Europe, North Africa, and Asia Minor, and perhaps further eastward ; but in this country and in Central Europe it would have been extinct long ago © had it not been protected. In Kashmir the red-deer is represented by the closely allied hangul, in North- Eastern India by the larger shou. A somewhat similar species to these is the North American wapiti, C. canadensis, still plentiful in the wooded western mountains. Like all the deer, the males of this species fight very much during the pairing season. As an example of this we may quote from Mr. T. Roosevelt, who describes a characteristic battle which he wit- nessed. He says: ‘Two bull elk were engaged in deadly combat while two others were looking on. It was a splendid sight. The great beasts faced each other with lowered horns, the manes that covered their thick necks and the hair on their shoulders bristling and erect.
