It contained grass seeds, among which I found ants at work, and seeds of the same grass still in their husks lay in the gallery leading up to the entrance of this cell; D 1, the same, further freed from the earth, and having part of one side removed, so as to show the interior and the small lower opening leading out from the bottom of the cell.

, p. 88, fig. A.—The nest of Cteniza fodiens, the lower part of which is seen in section lying in the earth, the door is artificially represented as partly open; A 1, surface of the door viewed from above; A 2, the spider; A 3, the spider deprived of its legs, from a specimen preserved in spirits [figs. A, A 1, A 2, and A 3, are of the natural size]; A 4, the spider viewed sideways, with the legs removed; A 5, the eyes, viewed from above and in front; A 6, the cephalothorax and falces; A 7, the left hand falx, viewed from the inner side; A 8, the fang of the same; A 9, the tarsal joint of the foremost right leg; A 10, one of the two larger and the smallest claw of the same [figs. A 4, 5, 6, 7, 8, 9, and 10, all magnified]. Fig. B, the door of a nest of the same kind, concealed by lichens, below which, on the left hand, the doors of two minute nests of Nemesia meridionalis are seen; B 1, the same, with the doors open; C, the door and mouth of tube of a nest similar to that at A; C 1, the upper surface of this door, which is slightly convex.

A, A 1, 2, and 3, of the natural size]; figs. A 4, 5, 6, 7, 8, 9, and 10 as in Plate VII., and magnified; B, a moss-covered lump of earth, in which the door of a nest of the same type as that at A lies concealed; B 1, the same, with the door open; C, the door and mouth of another similar nest, showing the claw marks on its under surface; D, the closed door of a third nest of the same kind; D 1, the same, opened.
