Characteristic forms of this order in northern Asia are the marmots (Arctomys) and the pikas, or tailless hares (Lagomys).
The fauna of the Tibetan Himalaya is essentially European or rather that of the northern half of the old continent, which region has by zoologists been termed Palaearctic. Among the characteristic animals may be named the yak, from which is reared a cross breed with the ordinary horned cattle of India, many wild sheep, and two antelopes, as well as the musk-deer; several hares and some burrowing animals, including pikas (Lagomys) and two or three species of marmot; certain arctic forms of carnivora - fox, wolf, lynx, ounce, marten and ermine; also wild asses.
