 somewhat quadrate in shape, rounded at the apex; it is furnished with hairs only.

The sternum is of a sub-pentagonal form, much broader behind than in front; its colour is dull yellowish-brown, and it is furnished with hairs, leaving two largish, bare, round, slightly impressed patches, not far from each other, in a transverse line near the middle.

The abdomen is short-oval in form, and very convex above; it projects a little over the base of the cephalothorax, and its upper side is of a purplish grey-brown hue, mottled with a pale dull whitish-yellow, and furnished sparingly with hairs. The sides and under side are of a uniform dull whitish-yellow. The spinners (four in number) are, as usual, of very unequal size, those of the superior pair longish, strong, three-jointed, and up-turned, the inferior pair short but stout, consisting of one joint only and pretty close together.

The female (as it is conjectured to be) of this species was described, in the work to which the present publication is supplementary, from examples found at Mentone. There is little doubt now but that it is not Ct. fodiens, Walck., but whether or not identical with the male above described is not absolutely certain. I think myself (with Mr. Moggridge, see p. 195) that it is so, in spite of some differences in the relative size of the eyes, the toothing of the under side of the falces, and the denticulation of the tarsal claws. With regard to the eyes and falces, I am not inclined to lay special stress upon these differences. It is found that in other groups of spiders whose cephalothorax varies very markedly
