become about the size of half a walnut, and resembled in its nearly semi-circular outline and size the surface of the door of her own nest. I was greatly pleased to be able to watch the creature at the work of excavation, a sight which I believe no naturalist has ever had before.
The legs took no part in the digging, and the palpi were but little used, the mandibles and their fangs being the implements chiefly employed. As soon as a little earth had been loosened and gathered up, the spider walked up to the edge of her excavation and deposited there her mouthful of particles of earth, separating and working the mandibles up and down in the effort to part with the pellet, which had been carried between the fangs and the mouth-organs. Each pellet was very small, and the operation appeared to be excessively tedious and laborious. I had expected to see the spider scrape out large quantities of earth at a time, and either drag it backwards or kick it out behind her as a terrier does when working at a rabbit-burrow; but no, every little pellet removed was carried forwards, and deposited separately on the "tip."
On the two following days, the 17th and 18th November, the spider remained almost inactive, and brooded over the cavity she had made, and which still remained too shallow to conceal or even contain her. At 4 P.M. on the latter day I made a hole for her in the earth, and, after some indecision, she took possession of it.
