282 SPECIFIC DESCRIPTIONS OP 



along tlie middle of the upper side of the abdomen, 

 agreeing exactly with Duges' figures in the TTegne 

 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 orne d'une fine ligne noire longitudinale, 

 un pen ondulee, presentant de nombreuses ramifica- 

 tions, s'etendant sur les parties laterales " (I.e. 

 p. 26). The males before me accord with this descrip- 

 tion, though (as M. Simon also remarks) the " serie 

 de fins accents bruns transverses" is " pen visibles et 

 souvent effaces" (I.e., 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 di- 

 rection ; 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 propor- 

 tionally smaller than that of JY. duMa, or of N. Man- 

 dersfjcrnw, Auss. [N. meridionalis, Cambr.) 



Another difference may here be noted between the 

 present species and the Montpellier ccementaria. M. 

 Simon [in lit.) separates his N. ccementaria from all
