THE LEMURS. 33 species, most of which belong to Madagascar, others to Africa, Asia, and the Indian Archipelago; the Zarside, which hail from Sumatra and Borneo; and the Chiromytde, of which the aye- aye is the representative. The Lemuride are divided into four sub-families by Professor Mivart. I, the Indri; II, the true Lemurs; III, the slow Lemurs and IV, the Galagos. The lemur is nocturnal in its habits and noiseless in its movements. Some of its species much resemble the cat in appearance though its four hands unmistakably demonstrate its order. Sir William Jones describes a Slow Lemur (Wycticebus tardigradus), which he had in his possession, as “gentle ex- cept in the cold season, when his temper seemed wholly changed.” This animal expressed great resentment when disturbed unseasonably. From half an hour after sunrise to half an hour before sunset he slept without any intermission, rolled up like a hedgehog: and as soon as he awoke he began to prepare himself for the occupations of his approach- ing day, licking and dressing himself like a cat—an operation — which the flexibility of his neck and limbs enabled him to perform very completely. He was then ready for a slight breakfast, after which he commonly took a short nap; but when the sun was quite set he recovered all his vivacity. “ Generally he was not voracious, but of grasshoppers he never could have enough; and passed the whole night during the hot season in prowling for them. He used all his paws indifferently as hands.” Mrs. Bowdich tells of one of these animals, procured by Mr. Baird at Prince of Wales Island, who shared a cage with a dog to whom he became greatly attached, while nothing could reconcile him to a cat, which constantly jumped over his back, causing him great annoyance. The Tarsier. The tarsier (Tarsius spectrum) is a small, kitten- faced animal with long hind legs, which enable it to leap like a frog. It is nocturnal in habit, and is found in Sumatra, Borneo, and elsewhere. © The Aye-Aye. The aye-aye (Chiromys madagascariensis) is 3
