32 NATURAL HISTORY IN ANECDOTE, The The fourth sub-family of the Cebide includes Douroucoull. several genera and a number of species, of these the Douroucouli (Wyctipithecus felinus) is one of the most interesting. It is a small monkey, measuring only thirteen inches, apart from its tail, which is eighteen inches long: It is catlike in some of its habits, sleeping during the day, and prowling about at night in search of food, which it finds in fruits, insects and small birds. It has a catlike mew, though it often makes a louder cry more resembling the noise of the jaguar. The Marmosets. The fifth family of the quadrumana com- prises the marmosets, of which there are two genera—the Hapale and the Midas. These are very small, measuring about eight inches without the tail, which is eleven inches long. The marmoset is one of the prettiest of the monkeys, and, though at first shy, soon becomes playful and affection- ate. Marmosets are one of the few species that breed in confinement. Sir William Jardine describes a marmoset who gave birth to three offspring in Paris. One of these, for some reason, displeased her, and she killed it, but upon the others beginning to suck the maternal instinct awoke, and she became as affectionate as she was before careless. “The male seemed more affectionate and careful of them than the mother, and assisted in the charge. The young generally | keep upon the back or under the belly of the female, and Cuvier observed, that when the female was tired of carrying them, she would approach the male with a shrill cry, who immediately relieved her with his hands, placing them upon his back, or under his belly, where they held themselves and were catried about until they became restless for milk, when they were given over to the mother who, in her turn, would again endeavour to get rid of them.” SUB-ORDER I. The lemurs and their allied forms make up The Lemurs. the remaining families of the quadrumana. These are three. The Lemuride, of which there are many
