It has been generally admitted that the great variety of this species renders a classification almost impossible. Different countries adopt special names for the varieties which inhabit the localities; the leopard may be termed a panther, or cheetah, or wild cat, or even a jaguar, but it remains a leopard, differing in size, colour, and form of spots, but nevertheless a leopard. I shall therefore accept that name as including every variety. Although the genus Felis embraces in its nomenclature all the various representatives, from the lion (_Felis Leo_) to the ordinary domestic cat, the two principal examples of the race, the lion and tiger, are totally distinct from all others in their natural characters. The leopard is far more daring; at the same time it is infinitely more cautious, and difficult to discover. No lion or tiger can ascend a tree unless the branches spring from within 4 or 5 feet of the ground; even then it would be contrary to the habits of the animal to attempt an ascent, although it might be possible under such favourable circumstances. A leopard will spring up a smooth-barked tree with the agility of a monkey; and there is a small species which almost lives among the branches (F. Macroscelis), from which it leaps upon its prey when passing unconsciously beneath. An examination of the skins of leopards from various portions of the globe exhibits a striking difference in colouring and quality of fur. We find the snow leopard, which inhabits the Himalayahs and other lofty mountain ranges, with a fur of great value, deep and exceedingly close, while the spots are not determined as distinct black, but are shaded off by gray. This species is generally found at altitudes of from 8000 to 10,000 feet, or even higher. In Manchuria and the Corea there is a species which is unknown in India; this is a large animal, with a peculiarly rich and deep fur when killed during winter; the black spots are exceedingly large, and are formed in rings. A skin in my possession measures 7 ft. 9 in. in length; the tail is full, and the fur long; this is unusually beautiful, and it must have inhabited some lofty altitude where the temperature was generally moderate. In Africa the leopards have almost invariably solid black spots, very close together upon the back, and becoming less crowded towards the belly and flanks. In Ceylon there are two distinct varieties-the large panther, generally about 7 ft. 6 in. in length, and a smaller leopard, which inhabits the mountains; in that island of misnomers they are both included in the name cheetah. In India there are several varieties, and the largest is generally distinguished as a panther. There is no animal more commonly distributed in the world than the leopard, and no tropical country is free from this universal pest, unless an island formation has excluded its unwelcome presence.
