Show 1905.] MAMMALS OF SOUTHERN CAMEROON'S. 81 when they come upon them. But some men I found in the region of the Ja bold enough to shoot darts headed with broad and sharp chisel-like blades from their guns, and thus kill elephants. When a native kills an elephant he secures a great prize, for a pair of good-sized tusks are a small fortune to him, and the supply of meat is enough for many villages. At a village on the Benito River I saw where the people, a few months before, had constructed a strong fence at the outskirts of their clearing, where a herd of elephants had been coming of nights to feed. Into the enclosure thus made they had managed to get the elephants, and had killed six or eight of them, shooting them from behind the stockade or from stations in large trees. Natives sometimes find elephants dead. These may sometimes be such as have been wounded by spears of the kind described above ; but I think that they are those that have died a natural death. A large elephant-skull that I once saw lying by a path in the forest had no sockets for the tusks, but only rudimentary holes the size of one's finger. The people say elephants are often destitute of tusks. T he Species of A nomalurus. The A nomctluri, which have in Fa ng and Bulu the generic name " ngui," are among the most strictly arboreal animals that exist. I never saw one, or heard of one having been seen, on the ground ; and I know that when .one falls to the ground wounded, it is helpless, and does not try to run away. They can ascend and descend large smooth tree-trunks or the inside of hollow trees, where an ordinary squirrel could not go. In such places they have a humping mode of progress like that of a Geometer caterpillar, and the sharp-pointed scales on the underside of the tail are pressed against the tree to aid them. They must be much aided also by the wonderful sharpness and strong curve of their claws. The claws of dead specimens were continually catching on things-on other specimens, the side of the vessel, or even my hand when handling them-and holding so that they were not easily shaken off-. I have never seen these Flying-Squirrels on the small outer branches of trees; but they must go on the outer branches, for they leap or sail through the air from one tree to another. I have often asked the natives what these animals eat. The answers showed ignorance : it was commonly said that they eat fruit or nuts ; I was also told that the 11 avemba ngui " (A. bee-crofti) eats " the flesh" of trees, that is, the soft cambium-layer under the bark. A greenish pulpy mass I have seen in the stomachs of some specimens seemed to confirm this. The species just referred to is generally found in the daytime clinging to the inside of large hollow trees, though sometimes, espe-ciallv towards evening, it is seen crouching against the outside of P roc.
