The nilgao inhabits open country with scrub or scanty tree jungle, also, in the Central provinces, low hilly tracts with open glades and valleys. He feeds on beyr (Zizyphus jujuba) and other trees, and at times even devours such quantities of the intensely acrid berries of the aonla (Phyllanthus emblica) that his flesh becomes saturated with the bitter elements of the fruit. This is most noticeable in soup, less so in a steak, which is at times not bad. The tongue and marrow-bones, however, are generally as much as the sportsman claims, and, in the Central provinces at least, the natives are grateful for all the rest.

He rests during the day in shade, but is less of a nocturnal feeder than the sambar stag. I have found nilgao feeding at all times of the day. The droppings are usually found in one place. The nilgao drinks daily, the sambar only every third day, and many are shot over water. Although he is such an imposing animal, the blue bull is but poor shooting, unless when fairly run down in the open. With a sharp spurt he is easily blown, but if not pressed will gallop for ever. In some parts of India nilgai are speared in this way. I myself preferred shooting them either from a light double-barrelled carbine or large bore pistol when alongside; the jobbing at such a large cow-like animal with a spear was always repugnant to my feelings. They are very tenacious of life. I once knocked one over as I thought dead, and, putting my rifle against a tree, went to help my shikaree to hallal him, when he jumped up, kicked us over, and disappeared in the jungle; I never saw him again. A similar thing happened to a friend who was with me, only he sat upon his supposed dead bull, quietly smoking a cigar and waiting for his shikarees, when up sprang the animal, sending him flying, and vanished. On another occasion, whilst walking through the jungle, I came suddenly on a fine dark male standing chest on to me. I hardly noticed him at first; but, just as he was about to plunge away into the thicket, I rapidly fired, and with a bound he was out of sight. I hunted all over the place and could find no trace of him. At last, by circling round, I suddenly came upon him at about thirty yards off, standing broadside on. I gave him a shot and heard the bullet strike, but there was not the slightest motion. I could hardly believe that he was dead in such a posture. I went up close, and finally stopped in front of him; his neck was stretched out, his mouth open and eyes rolling, but he seemed paralysed. I stepped up close and put a ball through his ear, when he fell dead with a groan. I have never seen anything like it before or since, and can only suppose that the shot in the chest had in some way choked him. I have alluded to this incident in my book on Seonee; it was in that district that it occurred.

The nilgao is the only one of the deer and antelope of India that could be turned to any useful purpose. The sambar stag, though almost equal in size, will not bear the slightest burden, but the nilgao will carry a man. I had one in my collection of animals which I trained, not to saddle, for such a thing would not stay on his back, but to saddle-cloth. He was a little difficult to ride, rather jumpy at times, otherwise his pace was a shuffling trot. I used to take him out into camp with me, and made him earn his grain by carrying the servants' bundles. He was not very safe, for he was, when excited, apt to charge; and a charge from a blue bull with his short sharp horns is not to be despised. In some parts the Hindoos will not touch the flesh of this animal, which they believe to be allied to the cow. It has much more of a horsey look about it. McMaster says that in some parts of the Coimbatore district the natives described this creature to Colonel Douglas Hamilton as a wild horse, and called it by a name signifying such. He also notices the resemblance of the Gondi name Guraya, to the Hindi Ghora.

[GENUS TETRACEROS.]

Horns four, conical, smooth, slightly bent forward at tip, the anterior ones very short, sometimes rudimentary, which has led to the distinction of a separate species by some naturalists; slightly ringed at the base. The posterior ones situated far back on the frontal bone, the anterior ones above the orbits; eye-pits small, linear; muffle large; feet-pits in the hind feet; no groin-pits; four mammæ; canine teeth in the males; females hornless. The skull is characterized by the large sub-orbital fossæ which occupy nearly the whole cheek. The various species—sub-quadricornutus of Elliot, iodes and paccerois of Hodgson—are but varieties of the following only Indian species.

[NO. 463. TETRACEROS QUADRICORNIS.]
The Four-horned Antelope (Jerdon's No. 227).

NATIVE NAMES.—Chowsingha, Chowka. Jerdon also gives Bherki, Bekra, and Jangli-bakra, but I have also heard these names given by natives to the rib-faced deer (Cervulus aureus); Bhir-kura (the male) and Bhir(female) Gondi; Bhirul of Bheels; Kotri, Bustar; Kond-guri, Canarese; Konda-gori, Telegu (Jerdon). Kinloch also gives Doda, Hindi.

HABITAT.—Throughout India, but not in Ceylon or Burmah.

Tetraceros quadricornis.
