A, A 1, 2, 3, and 4 are of the natural size]; A 5, the spider viewed sideways, with the legs removed; A 6, the eyes, viewed from above and in front; A 7, the cephalothorax and falces; A 8, the left hand falx viewed from the inner side; A 9, the fang of the same; A 10, the tarsal joint of the foremost right leg; A 11, one of the two larger and the smallest claw of the same [figs. A 5, 6, 7, 8, 9, 10, and 11, magnified]; B, a mass of earth containing the minute nest of a young spider (_N. meridionalis_); B 1, the lower door of this nest; B 2, the spider [figs. B, B 1, and 2, of the natural size].

Plate X., p. 100, fig. A.--Part of a nest of _N. meridionalis_; B, the new and larger upper door of a nest of this spider, with the former and smaller upper door partially united to it; C, another example of enlargement in the upper door of the same spider, showing traces of two previous doors now incorporated. [All the figures are of the natural size.]

Plate XI., p. 105, fig. A.--The upper part of a nest of _N. meridionalis_ concealed in a plant of Ceterach fern; A 1 and A 2, a minute cork-door, closed and open, which I saw constructed by a very young spider [either _Cteniza fodiens_, or, more probably, _Nemesia cæmentaria_] at the mouth of a hole in the mass of earth containing the nest of _N. meridionalis_ figured at A. This hole may be seen on the right of the fern. B, the door of a small nest of _N. meridionalis_, as seen from above, in its natural position in a steeply sloping bank; B 1, part of the same nest placed in an upright position, and showing the surface door open and the lower door closing the branch; B 2, the same with the lower door pushed across so as to close the main tube; B 3, 4, and 5, different views of this second door. [All the figures in this plate are of the natural size.]

Plate XII., p. 106, fig. A.--The nest of _N. Eleanora_ with the surface door artificially represented as being open; A 1, the outer side of the surface door of the same nest into which mosses of two kinds are woven; A 2, the second door of the same nest; A 3, the spider; A 4, the same deprived of its legs, from a specimen preserved in spirits [figs. A, A 1, 2, 3, and 4 are of the natural size]; fig. A 5, the spider viewed sideways, with the legs removed; A 6, the eyes viewed from above and in front; A 7, the cephalothorax and falces; A 8, the left-hand falx viewed from the inner side; A 9, the fang of the same; A 10, the tarsal joint of the foremost right leg; A 11, one of the two larger and the smallest claw of the same [figs. A 5, 6, 7, 8, 9, 10, and 11, magnified]; fig. B and B 1, the upper part of the tube and door of a nest of _N. Eleanora_ which partially projected beyond the surface of the earth and was clothed with living moss. [Figs. B and B 1 are of the natural size.]
