III. _Cteniza Moggridgii_, Cambridge (formerly described under the name of _Ct. fodiens_[154]), one of the many builders of a nest of the cork type; I have hitherto found this spider only at Mentone and San Remo. It will probably be discovered in shady valleys in the neighbourhood of Nice. [Footnote 154: _Ants and Spiders_, p. 89.] IV. _Ct. fodiens_, Camb. (_Ct. Sauvagii_, Rossi ex Simon): large nest of cork type; inhabits Corsica. It has been said that the species found near Pisa (_Ct. Sauvagii_) is the same as that which is so common in Corsica, but it is desirable to have further confirmation of this. V. _Ct. Californica_, Camb.--Large nest of cork type. Found near Visalia, about 350 miles south of San Francisco, by Mr. G. Treadwell. VI. _Nemesia cæmentaria_, Latr.--Nest of cork type. Only known with certainty to inhabit the neighbourhood of Montpellier. VII. _N. Moggridgii_, Camb. (formerly described under the name of _N. cæmentaria_, Latr.[155])--Nest of cork type; is found at San Remo, Mentone, Cannes, Hyères, and Marseilles. Its range probably extends some distance to the eastwards, but I doubt whether it does so towards the west, for there I think it likely that it will be found to be replaced by the typical _cæmentaria_. [Footnote 155: _Ants and Spiders_, p. 92.] VIII. _N. Simoni_, Camb.--Nest of the single-door unbranched wafer type, discovered at Bordeaux in May, 1874. IX. _N. suffusa_, Camb.--Nest of single-door branched wafer type, discovered at Montpellier in May, 1873. X. _N. Eleanora_, Camb.--Nest of double-door unbranched wafer type; is found at San Remo, Mentone, Cannes, Vaucluse near Avignon. M. Simon says[156] he has also found it at Digne, in the Basses Alpes. [Footnote 156: E. Simon, _Aranéides nouveaux du Midi de l'Europe_, in "Mém. Soc. Roy. Sc. de Liège," 2^{me}. ser. tom. v. p. 30.] XI. _N. congener_, Camb.--Nest of double-door branched wafer type; discovered at Hyères in May, 1873. XII. _N. Manderstjernæ_, Koch, in Ausserer (formerly described under the name of _N. meridionalis_, Costa).[157]--Nest of double-door, branched, cavity wafer type; is found at San Remo, Bordighera, Mentone, Nice, Cannes, and Hyères (apparently very rare at the last-named place). [Footnote 157: _Ants and Spiders_, p. 101.] XIII. _N. meridionalis_, Costa.--Structure of nest doubtful (see description in _Ants and Spiders_, p. 138). Found near Naples and in Ischia. M. Simon has discovered a spider in Corsica which he considers the same as that described by M. Costa under the name of _meridionalis_, but it seems desirable, in order thoroughly to establish this conclusion, that specimens of the spiders and their nests from these distant habitats should be compared together.
