The Indian Antelope, of which the specimen in the Tower constitutes a remarkable and highly interesting variety, is not only one of the most beautiful, but also the most celebrated species of the group. It occupies the place of Capricorn in the Indian Zodiac, and is consecrated to the service of Chandra or the Moon. In size and form it closely resembles the Gazelle of the Arabs, the well known emblem of maiden beauty, typified, according to the poets, in the elastic lightness of its bound, the graceful symmetry of its figure, and the soft lustre of its full and hazel eye. From this truly elegant creature our Antelope is, however, essentially distinguished by several striking characters. Its horns, which are peculiar to the male, are spirally twisted, and form, when fully grown, three complete turns; they are closely approximated to each other at the base, but diverge considerably as they proceed upwards. They occasionally attain a length of nearly two feet, and are surrounded throughout by elevated and close-set rings. The two horns taken together have frequently been compared to the branches of a double lyre. The extremity of the nose is bare, forming a small and moist muzzle; the sub-orbital openings are larger and more distinct than in almost any other species; and the ears are pointed and of moderate size. The natural colours vary with the age of the animal, but correspond in general pretty closely with those of the common deer. They may be shortly described as fawn above and whitish beneath, becoming deeper with age, and lighter in the females than in the males. The occasional stripes of a lighter or darker colour, which are generally visible on various parts of the body, can scarcely be considered as occurring with sufficient regularity to allow of their being described as characteristic of the species.
