It seems very improbable, however, that it should be mainly intended as a safety place for the eggs or offspring; at least if this were the case we should not expect to find it, as we do, in the nests of very young spiders (fig. B, Plate IX.), which could have no use for it. The large spider and its nest figured at A and A 3 in Plate IX. were taken at Mentone on March 17, 1872, and the following is the technical description of the species, written by Mr. Pickard-Cambridge:-- Nemesia Meridionalis. Plate IX. Syn. _Mygale meridionalis_ (Costa). _Fauna del Regno di Napoli_, p. 14, Pl. I., figs. 1-4, ad partem. Female adult, length 11 to 13 lines. This spider is very nearly allied to _N. cæmentaria_ both in general structure and colours, but it may be distinguished by the more elongate form both of the cephalothorax and abdomen; the colours also of the present species are more distinctly distributed; a well-defined narrow marginal band, irregular on the inside, surrounds the thorax; and the caput has a large curved patch of the same on either side of the ocular area, with a broad tapering band tinged with orange, which runs from immediately behind the eyes to the thoracic junction, where it ends in a point. The transverse diameter of the ocular area is also less in proportion to its longitudinal diameter than in _N. cæmentaria_, and the eyes are all smaller, but placed on a similar oval eminence, and several bristles are directed forwards from the middle of the lower margin of the clypeus, while one or two others are found in the ocular area, and three or four more (long, strong, and nearly erect) form a longitudinal row along the middle of the central tapering thoracic band. The _Falces_ are deeply yellow-brown, with two to three elongate oval patches or short longitudinal parallel bands on their upper sides; in their armature the falces are similar to those of _N. cæmentaria_. The _Labium_ appeared to be less broad in proportion to its height, and the _Sternum_ smaller and of a more oval form than in that species. The _Abdomen_ is similarly marked, though the chocolate-brown markings appeared to be less deep and dense, being more broken up, but still forming several fairly defined, bold, and broad angular bars or chevrons on the upper side. The inferior spinners, though small (like most of the corresponding pair in species of this family), are yet considerably stronger than in _N. cæmentaria_.
