It consists of a piece of pure white paper, an inch and a half broad, stuck flat on the wall; under this some forty or fifty eggs are placed, and then a quarter of an inch of thinner paper is put round it, apparently to fasten the first firmly.

When making the paper the spider moves itself over the surface in wavy lines; she then sits on it with her eight legs spread over all for three weeks continuously, catching and eating any insects, as cockroaches, that come near her nest.

After three weeks she leaves it to hunt for food, but always returns at night: the natives do not molest it.
A small ant masters the common fly by seizing a wing or leg, and holding on till the fly is tired out; at first the fly can move about on the wing without inconvenience, but it is at last obliged to succumb to an enemy very much smaller than itself.
A species of Touraco, new to me, has a broad yellow mask on the upper part of the bill and forehead; the topknot is purple, the wings the same as in other species, but the red is roseate.

The yellow of the mask plates is conspicuous at a distance.
A large callosity forms on the shoulders of the regular Unyamwesi porters, from the heavy weights laid on them.

I have noticed them an inch and a half thick along the top of the shoulders.
