184 THE ESSEX NATURALIST. Spiders, and that was of two belonging to James Adams, of Dunfermline. These, too, had been brought over with bananas, and Adams kept one in captivity for two and a half years, during which time it moulted five times, though it increased very little in size. These moults occurred twice a year—one in April and one in October. During six months this one took no food at all, and at one moult it lost a limb, but this reappeared when it next changed its skin. Since the spider observed by myself moulted in October also, it will be interesting to see if it can be kept through the winter, and if it moults again next April. The other specimen that James Adams kept, moulted only once each year, in June or July. He kept this for three and a half years, and it eventually lost its life whilst undergoing a moult. The moult is evidently quite a serious matter, involving far more than the mere casting off of an external coat—it often loses limbs in the process, and runs the risk of losing its life in trying to discard the old integument. However, this particular spider appears to have managed it very well indeed, and besides emerging with all limbs intact and dressed in a richly-coloured new coat, it has presented us with this beautiful specimen of its discarded skin.
