There are several local races, one of which was long regarded as a separate species under the name of the Moor macaque, Macacus maurus.
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.
WANDERU (WANDEROO), the native name for the species of langur monkeys (Semnopithecus) inhabiting the island of Ceylon; but in India commonly misapplied to the lion-tailed macaque, Macacus silenus (see Primates).
Among these are two monkeys of the genera Macacus and Cercopithecus, a stag (Cervus hippelaphus), a small hare, a shrewmouse, and the ubiquitous rat.
This monkey, Macacus inuus, is light yellowish-brown above and yellowish-white below, with the naked part of the face flesh-coloured.
The Formosan fauna has been but partially ascertained; but at least three kinds of deer, wild boars, bears, goats, monkeys (probably Macacus speciosus), squirrels, and flying squirrels are fairly common, and panthers and wild cats are not unfrequent.
