Animals of small size and delicate graceful form, which are separated from the deer and oxen by certain peculiarities which approximate them to the swine in their feet. They are, however, ruminants, having the complex stomach, composed of paunch, honeycomb-bag and reed, the manyplies being almost rudimentary; but in the true ruminants the two centre metacarpals are fused into a single bone, whilst the outer ones are rudimentary. In the pig all the metacarpal bones are distinct, and the African Tragulus closely resembles it. The Asiatic ones have the two centre bones fused, but the inner and outer ones are entire and distinct as in the swine. The legs are, however, remarkably delicate, and so slight as to be not much thicker than an ordinary lead pencil. The males have pendant tusks, like those of the musk and rib-faced deer.
