[Footnote 70: The lower door here, as in the branched nest (see above, p. 100), is sometimes united to the silk of the tube below by two nearly triangular gussets of silk, when, instead of being free except at the hinge, as I have represented it (Plate XII.), it is surrounded on either side by silk and only free at the extremity away from the hinge. This does not, however, alter the function of this door in any way. It may be that these lower doors are always attached from below in this way, but it is very difficult to be sure of this, as they readily break away from the surrounding silk, when they appear quite free, as in my drawing. It was not until I adopted the plan of stuffing the tube full of cotton wool before removing the surrounding earth that I detected this fragile attachment.] I have observed some variation as to the exact proportions of these doors, and it is quite possible that in many cases they are specially adapted to meet peculiarities in the curvature of the tube. The nest and spider drawn at figs. A and A 3 of Plate XII. were first discovered by the Honourable Mrs. Richard Boyle at Mentone, on March 26th, 1872, and the following is the description of the species kindly prepared by Mr. Pickard-Cambridge:-- Nemesia Eleanora, sp. nov. Plate XII. Female adult, length 11 to 12 lines. This spider, which has (like _N. meridionalis_) probably been confused with its near ally _N. cæmentaria_, is yet easily distinguished from both by its deeper and richer colouring, as well as by other characters.
