on the under, as well as the upper, side of the abdomen, lead me to believe that it is of a different, and hitherto undescribed species, though probably very closely allied to some others, especially to Nemesia Manderstjernæ (N. meridionalis, Cambr., described, p. 283); in the present species however the hind-lateral eyes are much larger in proportion than in N. Manderstjernæ.

M. Eugène Simon (l.c.) describes, as N. cæmentaria, Latr., both sexes of a spider found by himself in the Pyrenees and Spanish mountain regions.
Languedoc and Provence are also given as localities, but it is not clear that he has himself found it in these latter parts, certainly not the male.
Two examples of this sex, found in the Pyrenees, and received from M. Simon, are now before me; these correspond, so far, very exactly to the description he gives (l.c.); the female I have not seen.
If the position assumed (p. 271) on Latreille's own authority, that the true male of N. cæmentaria, Latr., (N. carminans, Latr.), has a bifid point to the prolongation of the palpal bulb, it is clear that the present species is distinct from that of Latreille.
M. Simon describes this palpal bulb as having its extreme point "simple et plus effilée" (i.e. more slender than in the preceding species he has described N. meridionalis). That the examples now before me,
