 along the middle of the upper side of the abdomen, agreeing exactly with Dugès' figures in the ''Règne Animal'' of Cuvier, quoted above (p. 271); while in M. Simon's Pyrenean spider, the abdominal pattern of the female described by him, does not agree with this: "il est orné d'une fine ligne noire longitudinale, un peu ondulée, présentant de nombreuses ramifications, s'étendant sur les parties latérales" (l.c. p. 26). The males before me accord with this description, though (as M. Simon also remarks) the "série de fins accents bruns transverses" is "peu visibles et souvent effacés" (l.c., p. 25); in one example this pattern is fairly distinct, in the other it is scarcely recognisable.

The present is a larger spider than N. incerta (the male found by M. Simon at Digne); it is also less distinctly marked both on the cephalothorax and abdomen. The position of the eyes is different, and so also is the palpal bulb; in that species the spine describes a simple curve with a strong outward direction; in the present it is slightly but perceptibly sinuous, and its general direction is ''parallel to the radial joint of the palpus''; the spines also at the upper fore extremity of the radial joint are 5-6 in number instead of three. The outer side of the genual joint of each of the legs of the third pair has three spines; that on the left side, however, of one example, has four. The palpal bulb also appears to be proportionally smaller than that of N. dubia, or of N. Manderstjernæ, Auss. (N. meridionalis, Cambr.)

Another difference may here be noted between the present species and the Montpellier cæmentaria. M. Simon (in lit.) separates his N. cæmentaria from all
