A peculiar form of baboon, Cynopithecus, and the singular ruminant, Anoa, found in Celebes, seem to have no relation to Asiatic animals, and rather to be allied to those in Africa.
ANOA, the native name of the small wild buffalo of Celebes, Bos (Bubalus) depressicornis, which stands but little over a yard at the shoulder, and is the most diminutive of all wild cattle.
The nearest allies of the anoa appear to be certain extinct buffaloes, of which the remains are found in the Siwalik Hills of northern India.
The smallest member of the group is the anoa of Celebes.
Large oxen also occur in the Lower Pliocene of India, although not closely allied to the living kinds; while in the same formation are found remains of bison (or [?] yak) and buffaloes, some of the latter being nearly akin to the anoa, although much larger.
Mammals are few in species, but remarkable, especially Macacus niger, an ape found nowhere else but in Bachian; Anoa depressicornis, a small ox-like quadruped which inhabits the mountainous districts; and the babirusa or pig-deer of the Malays.
