. The cyclopædia of anatomy and physiology. Anatomy; Physiology; Zoology. 216 QUADRUMANA. monstrated that it is not a Vespertilio but a Lemur, and that it forms in this way a tran- sition from the Lemurince to the Cheiroptera, The author of the article CHEIROPTERA in this Cyclopedia has adopted the same views, and 1 agree with them, including the Galeo- pithecus in my present paper. The Galcojn- thecus, then, is a Lemur, with the extremities connected by a bat-like membrane, or, in other words, surrounded by a thin skin, which they support as the framework of the umbrella sustains its covering. By this singular struc- ture, the animal while jumping is suspended in the air, yet without the power, as the Bats, of a continued flight. The fingers of the hands are not longer than those of the feet, and pro- vided in both with long and sharp incurvated claws. They dwell upon trees in the Indian Archipelago, and feed upon insects, and, per- haps, little birds. They sleep, as the Bats, suspended by their hind legs, with their head downwards. According to the observations of WATERHOUSE, their dentition is as follows : . 2—2 . 0—0 f , incisors, - —; canines, ; false molars, - ; true molars, - —=34>. The form of -&—* 4—4? these teeth is very strange. The anterior incisor of each side in the upper jaw is of a small size and compressed form, suddenly dilated above its insertion in the jaw, serrated at the edge, and presenting three or four nearly equal denticulations. The second in- cisor on either side resembles the first false molar in form, and, like that, has two fangs. The first false^molar is compressed, of a tri- angular form, and has the anterior and pos- terior edges serrated. The second false molar is less compressed than the first, and divided into two nearly equal, acutely pointed, trian- gular cusps ; the apex of the posterior cusp is directed inwards. The triangular grinding surface of each of the true molars consists of three pointed cusps. The
