Mr. Saunders[62] gives admirable figures and descriptions which show us at once that these nests, which he discovered in rather elevated situations in the island of Zante, are of the cork type; but, in this case, the entire door does not shut flush with the surface, as in ordinary cork nests, but has a short spur-like projection above and behind the hinge, serving, as is conjectured, like a lever, by pressing on which from the outside the lid may easily be raised.[63] When I come to speak of the manner of constructing and repairing nests I shall have occasion to refer to these nests again. [Footnote 62: Sydney Smith Saunders. Description of a Species of Mygale from Ionia, in Trans. Ent. Soc. London, 1839, vol. iii. p. 160, Plate IX.] [Footnote 63: I must own to some hesitation about accepting this explanation, though I am not prepared to offer any other.] I have not as yet found any nests on the Riviera which can be said to correspond accurately with those of _Ct. ionica_, the only builders of cork nests yet discovered in this district being _Cteniza fodiens_ and _Nemesia cæmentaria_. This latter species is described by Mr. Pickard-Cambridge,[64] in the following terms:-- [Footnote 64: See above, p. 88.] Gen. Nemesia (Savigny). Nemesia cæmentaria. Plate IX. Syn. _Mygale cæmentaria_ (Latr.), _H. N. des Crust._ t. vii. p. 164. _M. cæmentaria_ (Walck), _Ins. Apt._ i. p. 135. Female adult, length 9 to 11 lines. _Cephalothorax_ rather elongate, oval, and somewhat truncated at each extremity; the caput is elevated and rounded on the sides and upper part, but less elevated than in _Cteniza_; the normal grooves and indentations are well marked, and the junction of the cephalic and thoracic segments is indicated by a strong deep impression or cleft, of a transverse, curved, or somewhat bent angular form, the curve or angle directed forwards. The colour of the cephalothorax is yellow-brown tinged with olive, the margins are paler, but have no distinctly defined marginal band. On the hinder part of the caput are three clear brown-yellow longitudinal stripes; the central one reaches from behind the two hind central eyes to the thoracic junction, the lateral ones converge a little to the same point, but do not reach nearly, in fact not much more than half way, to the eyes. The clypeus is of a clear brown-yellow colour also, and on either side of it (extending from each fore lateral eye), is an irregular patch of the same. The ocular region and clypeus are furnished with a few strongish black bristles, and the three yellow stripes above mentioned have a few more, those on the central stripe being the longest and strongest, and disposed in a single longitudinal row.
