Of the former no less than eleven are peculiar, including two which there is reason to believe may have been recently carried into other islands by man.

Three species which have a tolerably wide range in the Archipelago, are: (1) The curious Lemur, Tarsius spectrum, which is found in all the islands as far westward as Malacca; (2) the common Malay Civet, Viverra tangalunga, which has a still wider range; and (3) a Deer, which seems to be the same as the Rusa hippelaphus of Java, and was probably introduced by man at an early period.
The more characteristic species are as follow: Cynopithecus nigrescens, a curious baboon-like monkey if not a true baboon, which abounds all over Celebes, and is found nowhere else but in the one small island of Batchian, into which it has probably been introduced accidentally.

An allied species is found in the Philippines, but in no other island of the Archipelago is there anything resembling them.

These creatures are about the size of a spaniel, of a jet-black colour, and have the projecting dog-like muzzle and overhanging brows of the baboons.

They have large red callosities and a short fleshy tail, scarcely an inch long and hardly visible.
