Uniting to the system of dentition, the general habit and many of the most striking peculiarities of the cats, some of the distinguishing features and much of the intelligence, the teachableness, and the fidelity of the dog, the Hunting Leopard forms a sort of connecting link between two groups of animals, otherwise completely separated, and exhibiting scarcely any other character in common than the carnivorous propensities by which both are, in a greater or less degree, actuated and inspired. Intermediate in size and shape between the leopard and the hound, he is slenderer in his body, more elevated on his legs, and less flattened on the fore part of his head than the former, while he is deficient in the peculiarly graceful and lengthened form, both of head and body, which characterize the latter. His tail is entirely that of a cat; and his limbs, although more elongated than in any other species of that group, seem better fitted for strong muscular exertion than for active and long-continued speed. From these indications it may be gathered that he approaches much more nearly to the feline than to the canine group: we shall therefore follow the example of zoologists in general, by referring him for the present and provisionally to the genus Felis, and proceed to point out more particularly the characters by which he is connected with, as well as those by which he is distinguished from, the rest of that formidable and extensive tribe. In the number and form of his teeth, in the asperity of his tongue, in the conformation of his organs of sense, and in the number of his claws, he accurately corresponds with the legitimate species of the genus Felis. The principal character in which he differs from them consists in the slight degree of retractility of these latter organs. Instead of being withdrawn within sheaths appropriated for the purpose, as in the whole of the cats properly so called, the claws of the Hunting Leopard are capable of only a very limited retraction within the skin, and are consequently exposed to the action of the ground on which they tread, their points and edges being thus rendered liable to be blunted by the constant pressure to which they are subjected, almost to the same extent as in the dogs. The slightest consideration of the uses to which the claws are applied by the whole of the feline tribe, in whom they are, in fact, in consequence of their extreme power and sharpness, organs of offence if possible more deadly and more destructive than the teeth, will teach us that the modification which has just been described in so important a part of their organization, must of necessity be accompanied by a corresponding change in manners and habits; and that convenience alone, and the want of analogous structure in any other animal, could justify us in continuing to class the Chetah among the cats, from whom he differs in so essential a particular.
