The so-called Common Macaque, or _Macacus cynomolgus_, represents the long-tailed section of the genus, and grows to be a powerful animal amongst the other small Monkeys, over a very wide extent of country. It lives in Java, Sumatra, Borneo, Celebes, Batchian, in the islands from Lombok to Timor, and in the Philippines. It is a quiet and tolerably amiable Monkey when young, but with years, it becomes a wild, savage, and very brutal creature. Even in menageries it is often nasty in its habits, and savage. So bad a character has it, that when the proper name to give it came under the criticism of Fred. Cuvier, he sought out those of all the wickedest and naughtiest men in Lempriere’s Classical Dictionary, and finally considering that _Irus_, who disturbed the domestic peace of the sublimely virtuous, industrious, and persevering Penelope, was the worst of the worst, he fixed his name to that of this Monkey. But Buffon had, not from his bad qualities, or from any resemblance to the Monkey in disposition, his name attached to it long before; so it was called Buffon’s Monkey, as well as the Hare-lipped, although one fails to recognise this condition in its face. To complicate matters, an English zoologist, who knew little of Penelope’s feelings or trials, mistook the word Irus, and wrote it Iris! The word Cynomolgus may be translated “a pilfering or a lewd dog,” so that it and Irus are very appropriate. The huge shoulders of the full-grown adult strike one, and its general clumsiness also. There is a large body, and the limbs are short for it, although the tail is long. The fur is rather short, and is of an olive-brown, spotted with black on the head and body, but it is grey on the limbs, and blackish on the tail. There is no “hare-lip” in this Monkey, but there is no hollow going from the nose to the upper lip as in man, and only a raised line.
