And now we will leave the nests of the cork type and their inhabitants, and turn to the more intricate group of nests belonging to the wafer type. Following the order indicated in the diagrams, we will begin with the simplest type of all, fig. C, and afterwards take the remaining types one after the other, advancing until we reach the most complex type, G. The nest represented diagrammatically at fig. C, in Plate XIV., is shown of the natural size in Plate XVI., with the spider (_Nemesia Simoni_, Camb.) which constructs it (fig. A 1). [Illustration: _Plate XVI._] It belongs to the single-door unbranched wafer type, of which one example has already been described in the West Indian nest (see _Ants and Spiders_, p. 79, fig. B in woodcut); for, though this latter has a shorter tube and a much stouter silk lining than is the case with its European representative, there does not appear to be sufficient difference to justify their separation as distinct types. This, which is the simplest known form of trap-door nest, is quite new to Europe, and the spider inhabiting it proves also to be one hitherto undescribed; it has received from Mr. Pickard-Cambridge, the name of _Nemesia Simoni_,[138] being so called in honour of M. E. Simon, the well-known arachnologist. [Footnote 138: Mr. Pickard-Cambridge describes _N. Simoni_ at p. 297 below. This species is remarkably well characterized, an assertion rarely to be made in the case of those _Nemesias_ of which, as in the present instance, the female only is known. The elevated, rounded, and glabrous caput at once distinguishes it, not to speak of other peculiarities. Mr. Pickard-Cambridge alludes to the presence, in the specimens forwarded to him in spirits, of two singular indentations on either side of the caput (fig. A 3, Plate XVI.). I did not observe this when these spiders were alive, but I remember that the caput of one of these spiders which had been injured in capture contracted and expanded spasmodically, presenting a painful resemblance to laboured breathing. I have not observed this in other spiders.] During last May (1874) we spent a few days at Bordeaux on our homeward route. While there my sister was fortunate enough to discover a single nest of this type when we were out together on a spider-hunt near the little village of Lormont, which is situated on the opposite bank of the river to that on which the city stands. We subsequently found these nests in tolerable abundance in a deep shady lane near a restaurant called Mon Répos, on the same side of the river, but rather farther up. Here the hedge banks were high, and the soil was composed of a fine even-grained loam of great depth, which permitted the spiders to carry their tubes very far down, some of them attaining a length of 15 inches. This made it very difficult to follow them throughout their whole course and so to assure oneself of the real structure of the nests, but I succeeded in doing this in twelve instances.
