338 REV. O. P. CAMBRIDGE ON THE [Feb. 20, 



their colour is yellow, slightly suffused in parts with brownish ; and 

 each tarsus terminates with a black claw-tuft. 



The palpi are of moderate length and strength ; they are of a yel- 

 low colour, except the humeral joint, which is brown, and the digital, 

 which is still darker ; the humeral, cubital, and radial joints are 

 thickly clothed with longish bristly white hairs ; the radial is shorter 

 than the cubital, and has its outer extremity produced into a short, 

 strong, reddish-brown, blunt-pointed apophysis, its point bent down- 

 wards ; the digital is of ordinary form, somewhat obliquely truncated 

 at its fore extremity, the truncated part having a fringe of convergent 

 whitish hairs : the palpal organs are of a deep brown colour, very pro- 

 minent, but of simple structure ; they are of a somewhat globular 

 shape, extending far backwards in a pointed form to the underside 

 of the cubital joint. The falces are small, conical, retreating, and of 

 a deep brown colour. 



The abdomen is short, but of a broad, flattened, oval form, trun- 

 cated in a somewhat straight line in front, and rounded behind ; its 

 upper surface has a corneous appearauce, and is of a brilliant glossy 

 dark steel-blue-black colour ; the sides and underside are yellowish 

 white, clothed with grey hairs ; the sides also have some short lon- 

 gitudinal, blackish, dash-like spots or markings ; the steel-blue 

 upperside resembles a sort of plate or covering, which does not ex- 

 tend backwards quite to the spinner. 



All the examples met with were males ; and it appeared to be the 

 most abundant of the Saltici on the plains of the Jordan, among 

 stones and dwarf stunted plants ; it was also found in various other 

 parts of Palestine and Syria. I suspect that the A. canescens (Sim.), 

 if not the female of A. conveniens, must be that sex of the present 

 species, different as it appears to be in the nature of the abdominal 

 integument. Probably A. canescens includes the female of both 

 these species, as well as S. approximans ; for the respective males are 

 very nearly allied in structure, and their females would most likely 

 be very difficult to separate, although the adult males present very 

 good distinctive characters. The present species is also probably 

 closely allied to S. nitidiventris (Luc), but it diffeiVin several strong 

 specific characters. 



Salticus approximans, sp. nov. 



Male adult, length 2 lines. 



In size and general form this species resembles S. politiventris, 

 to which it is certainly nearly allied ; but the cephalothora.v has, be- 

 sides the broad marginal band of white hairs, a similar white spot 

 behind each lateral eye of the front row, and an oblique, short, white 

 bar or band of the same nature on the occiput behind each eye of 

 the third row. 



The legs are similar in colour to those of the foregoing species, as 

 are also the palpi ; but I could not discover any apophysis at the 

 outer extremity of the radial joint ; and there appeared to be no 

 truncation at the extremity of the digital, which was of the same 

 colour as the other joints ; but the palpal organs are very similar.
