18/2.] SPIDERS OF PALESTINE AND SYRIA. 337 



some long, black, recurved, erect, bristly hairs on the fore part of the 

 upper side. 



This plainly marked but distinctly characterized Spider is possibly 

 the male of A. candidus (Sim.), which is found in the same locality. 



A single adult male was met with among stones at Jerusalem. 



Salticus cognatus, sp. nov. 



Male adult, length 2f lines. 



This Spider nearly resembles, and is exceedingly closely allied to, the 

 last-described species, £. conveniens ; it is, however, larger. The ce- 

 phalothorax is flatter («. e. the slope forwards, from the middle of the 

 ocular area to the front row of eyes, is much less abrupt, the profile 

 line of the caput forming a more gentle and regular curve) ; the 

 cephalothorax is jet-black, but is entirely without pubescence. This 

 character seemed to be constant in all the ten examples met with, 

 and therefore is not, I think, due to denudation. 



The abdomen is black, clothed with a reddish-yellow pubescence, 

 similar to that of S. conveniens, and very liable to partial denudation, 

 but it was quite unicolorous ; in no example was there any trace of 

 either pale or dark spots on the hinder half. 



The palpi are remarkably similar to those of S. conveniens, but the 

 apophysis at the outer extremity of the radial joint seems to be rather 

 stronger and not bent downwards. The general hue and appearance 

 of the legs is darker than in the other species named, while in some 

 examples there is a large proportion of white hairs and pubescence 

 on them. 



Ten examples of the adult male were found among stones and 

 rocks and dwarf plants near Ain-Ata, on the skirts of the Lebanon. 



Salticus politiventris, sp. nov. 



Male adult, length 2 lines. 



This species, though so very different in appearance, is certainly 

 closely allied to both S. conveniens and the species next to be de- 

 scribed (S. approximans) . 



The cephalothorax is large ; its highest part is in a line with the 

 two hindmost eyes, whence it slopes both backwards and (more 

 sharply) forwards ; there is also a strongish indentation close behind 

 each of those eyes ; it is glossy, of the deepest black-brown, with the 

 ocular area quite black, and a broad marginal band of white hairs, 

 occupying nearly the whole of the sides of the cephalothorax, and 

 running completely round it in front close beneath the eyes of the 

 foremost row. Occasionally an example occurs with this band raised 

 above the margin, showing a brown-black band between it and a 

 narrow white marginal line. Each of the eyes of the second row 

 is, if any thing, slightly nearer to the fore lateral eye on its side 

 than to the hind lateral, but is in the same straight line with 

 them. 



The legs are rather long and tolerably strong ; those of the first 

 and second pairs are the strongest, but not excessively so ; and they 

 are furnished with hairs (both white, yellowish, and black) and spines;
