In India and Tibet there are two peculiar species of small Antelopes, the true Four-horned and the Brown Indian Antelope. In the former of these, known also as the Chikarah, different from what is found as a natural condition in any other living animal, there are two pairs of well-developed horns; the hinder, which are the larger, being five inches long, in the usual situation; the smaller, an inch and a half long, are close together not far behind the eyes. In the Brown Indian Antelope the anterior pair of horns are rudimentary, and nothing more than knobs. All these horns are straight and conical. Neither species is common. Their size is about that of the Arabian Gazelle; their colour a reddish-brown, becoming lighter below; the hair is coarse; the female is hornless. Captain Kinloch says of them that “four-horned Antelopes are generally found alone, or frequently in pairs; they conceal themselves in long grass or among low bushes, and somewhat resemble hares in their habits. They are seldom to be seen out feeding, but usually jump up at the feet of the hunter and bound away at a great pace.” THE WATER ANTELOPES.[12] The NAGOR, the REITBOK, the LECHÈ, the AEQUITOON, the SING-SING, and the WATER-BUCK are closely allied African Antelopes, with good-sized horns (only present in the males), which are transversely wrinkled, curved forwards, and a little inwards at the tips. Most of them are water-loving animals, and abound in marshy districts on the banks of rivers. The Nagor is a little more than two feet and a half in height at the shoulder, the horns being six inches long, and the tail ten inches. The colour of the long, loose hair is fulvous-brown above, white below. The Reitbok is of a grizzly ochreate colour. Its height is nearly three feet, the horns being twelve inches long. According to Dr. Kirk, the species is “commonly found feeding in small herds; in the heat of the day it rests in long grass, and may be approached within fifty yards before starting. It seldom runs far without stopping to look round. Before again making off it gives a shrill whistle, as it does often when first started. Should the female have young unable to run far, and danger near, she places her foot on the shoulder and presses it to the ground; after which it never moves until almost trodden upon, and is expected to remain in the same spot until the return of the mother.” The Lechè is of a pale brown colour above and white below. Sir John Kirk says it “is a water Antelope, frequenting damp, marshy places, and taking to impassable swamps, among reeds and papyrus. It goes in considerable herds, accompanied by several males, mingling often with the ‘Poku,’ another Antelope peculiar to that region (the valley of the Zambesi). In the distance the Lechè may be known by the peculiar way in which it allows its horns to recline back, almost touching the withers.” The POKU, Vardon’s Antelope of Livingstone, is smaller than
