Of the rhinoceros, three distinct varieties are enumerated, two with a single and one with a double horn. The most familiar is the _Rhinoceros unicornis_, commonly found in the Brahmaputra valley. It has but one horn, and is covered with massive folds of naked skin. It sometimes attains a height of 6 ft.; its horn, which is much prized by the natives for medicinal purposes, seldom exceeds 14 in. in length. It frequents swampy, shady spots, and wallows in mud like a pig. The traditional antipathy of the rhinoceros to the elephant seems to be mythical. The Javan rhinoceros (_R. sondaicus_) is found in the Sundarbans and also in Burma. It also has but one horn, and mainly differs from the foregoing in being smaller, and having less prominent "shields." The Sumatran rhinoceros (_R. sumatrensis_) is found from Chittagong southwards through Burma. It has two horns and a bristly coat. Wild hog. The wild hog (_Sus cristatus_) is well known as affording the most exciting sport in the world--"pig-sticking." It frequents cultivated situations, and is the most mischievous enemy of the villager. A rare animal, called the pigmy hog (_S. salvanius_), exists in the _tarái_ of Nepal and Sikkim, and has been shot in Assam. Its height is only 10 in., and its weight does not exceed 12 lb. Wild ass. The wild ass (_Equus hemionus_) is confined to the sandy deserts of Sind and Cutch, where, from its speed and timidity, it is almost unapproachable. Sheep and goats. Many wild species of the sheep and goat tribe are to be found in the Himalayan ranges. The _Ovis ammon_ and _O. poli_ are Tibetan rather than Indian species. The _urial_ and the _shapu_ are kindred species of wild sheep (_Ovis vignei_), found respectively in Ladakh and the Suleiman range. The former comes down to 2000 ft. above the sea, the latter is never seen at altitudes lower than 12,000 ft. The _barhal_, or blue wild sheep (_O. nahura_), and the _markhor_ and _tahr_ (both wild goats), also inhabit the Himalayas. A variety of the ibex is also found there, as well as in the highest ranges of southern India. The _sarau_ (_Nemorhaedus bubalinus_), allied to the chamois, has a wide range in the mountains of the north, from the Himalayas to Assam and Burma. Antelopes.
