Equus Burchellii.

The well known group of which the Horse, the Ass, and the Zebra constitute the leading species, is distinguished from all other quadrupeds by the form of their hoof, which is single and undivided, rounded in front, of considerable thickness, and enveloping the extremity of their only apparent toe. They have in each jaw six powerful cutting teeth, accompanied on either side by the same number of grinders with square crowns flattened at the top: the males have two canines in the upper jaw, and frequently in the lower also; and this structure is sometimes shared by the females of the domesticated races. Between the canines and the molars there is a vacant space, which, our readers scarcely need to be reminded, receives the bit, the small but irresistible instrument by means of which man has for ages exercised the most complete control over the services of these useful animals. Although purely and essentially herbivorous, their anatomy, as well as their habits, separates them most thoroughly from the Ruminants, and approximates them in several respects to the Pachydermatous order, with which, in spite of their many discrepancies, both physical and moral, M. Cuvier has associated them. It is needless to point out the incongruity of this union, and it would be equally so to say more of the general form and external characteristics of a group, the principal species of which are so constantly before our eyes.

It may, however, be observed, that it has been proposed to divide it into two distinct genera, the one containing the Horse alone, and characterized by the flowing tail uniformly covered with long hair, by the absence of a line of darker coloured hairs along the back, and by the presence of callous protuberances on the hind legs as well as on the fore: the other comprehending the Asses and Zebras, and distinguished by the tail having a brush of long hairs at its extremity only, by the presence of the dorsal line, and the absence of the protuberances on the posterior legs. Such a division, resting as it does on striking but not very essential differences, may fairly be admitted for the purpose of separating the genus into sections; but can hardly be regarded as founded on characters of sufficient importance to disunite so well marked and strongly connected, as well as so limited, a group. In the same paper in which this new arrangement was proposed, the beautiful animal which we have now to describe was first specifically distinguished by Mr. Gray from the Common Zebra, with which it had previously been confounded, and characterized by him under the name of the Asinus Burchellii. Still there exists so much confusion between the two Zebras, many naturalists falling into the same error with Mr. Burchell, who first remarked the distinction between them, and regarding the present animal as the Zebra of zoologists, and the common one in reality as the new species; while others have absolutely counterchanged a part of the characters of each, and thus made confusion worse confounded; that we cannot do better than describe with some little detail the markings of the individual now before us.

The ground colour of its whole body is white, interrupted by a regular series of broad black stripes extending from the back across the sides, with narrower and fainter ones intervening between each. Over the haunches and shoulders these stripes form a kind of bifurcation, between the divisions of which there are a few transverse lines of the same colour; but these suddenly and abruptly cease, and are not continued on the legs, which are perfectly white. Along the back there is a narrow longitudinal line, bordered on each side with white. The mane is throughout broadly and deeply tipped with black, and is marked by a continuation of the transverse bands of the neck. The lines of the face are narrow and beautifully regular; from the centre of the forehead they radiate downwards over the eyes; along the front of the muzzle they are longitudinal, the outer ones having a curve outwards; and on the sides they form broader transverse bands. From the confluence of these bands on the extremity of the muzzle, the nose, and the lower lip, those parts become of a nearly uniform blackish brown. The tail is white: there is no longitudinal ventral line: and a large black patch occupies the posterior part of the ear near the tip. The hoofs are moderately large, deep in front, shallow behind, and much expanded at their margin.

Of the habits of these animals in a state of nature we know but little. They inhabit the flat parts near the Cape of Good Hope, the common Zebra being confined to the mountains. All the attempts that have been made to domesticate either the one or the other, and to render them serviceable, have hitherto failed; but there seems no good reason why they should not, with proper management, be brought as completely under subjection as the other species of the genus. The subject of the present article, which has now been about two years in the Menagerie, will suffer a boy to ride her about the yard, and is frequently allowed to run loose through the Tower, with a man by her side, whom she does not attempt to quit except to run to the Canteen, where she is occasionally indulged with a draught of ale, of which she is particularly fond.
