APE, a sooty, black, short-tailed, and long-faced representative of the macaques, inhabiting the island of Celebes, and generally regarded as forming a genus by itself, under the name of Cynopithecus niger, but sometimes relegated to the rank of a subgenus of Macacus. The nostrils open obliquely at some distance from the end of the snout, and the head carries a crest of long hair. There are several local races, one of which was long regarded as a separate species under the name of the Moor macaque, Macacus maurus. (See PRIMATES.)
