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

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;
