straight and almost vertical direction to the fore lateral eye on either 

 side, dividing the side of the cephalothorax from the clypeus, while 

 the whole of the sides of the cephalothorax, as well as the clypeus, in 

 the present species is undivided by any such band ; in one example 

 only out of many there was a narrow black marginal line, and the 

 clypeus was suffused with brown-black. From S. vaillantii it may 

 be also distinguished by the central longitudinal yellow band on the 

 cephalothorax stopping at the hinder row of eyes, while in that 

 species it runs through the ocular area to the clypeus ; it is also 

 broader in general, though more sharply constricted transversely at 

 the beginning of the hinder slope than in the two species men- 

 tioned. In one example of the present species there was a con- 

 spicuous roundish patch of white hairs near the centre of the 

 ocular area, but quite separate and distinct from the central thoracic 

 band. 



The palpi in all three species are remarkably similar ; in all the 

 humeral joint has a conspicuous tuft of prominent hairs on the outer 

 side near its extremity, but this is perhaps most conspicuous in the 

 present species ; the radial joint is slightly shorter than the cubital, 

 and its outer extremity is produced into a tapering, sharp-pointed, 

 moderately long apophysis ; the digital joint is large, broad near its 

 base, and rather constricted forwards ; the palpal organs are promi- 

 nent near their base, projecting backwards over the radial joint ; and 

 a filiform black spine curves round them, adhering closely to the 

 inner edge of the digital joint. 



The female is rather larger than the male, but resembles it in 

 general colours and character. 



Adult and immature examples of both sexes were found on walls, 

 rocky banks, and among stones on the plains of the Jordan. An 

 adult male was also met with at Rasheiya. 



SALTICUS HELIOPHANOIDES, Sp. nOV. 



Male adult, length rather more than 2 lines. 



This Spider is very closely allied to 5 1 . delectus, Cambr., supra, 

 nearly resembling it in general colours and markings, but distin- 

 guishable by the dark colour of the legs, which are mixed black and 

 brown, especially those of the first pair, and by the absence of any 

 longitudinal curved stripes on the underside of the abdomen, the 

 underside being, in both examples found, of a vinous-brown colour, 

 thinly clothed with short hoary hairs. 



The palpi, while similar in the position and general character of 

 the prominences &c. of the different joints, have all these more 

 strongly marked and developed ; and a similar observation applies 

 also to the palpal organs. The resemblance, therefore, in this 

 Spider to those of the Heliophanus group is more marked than in 

 S. delectus. 



An adult male was found on the road from Kedes to Banias, and 

 another on the road from the Lebanon to Beirut : this last example 

 is considered by M. Simon to be distinct from the former ; but a 

 careful examination of the palpi failed to show any structural differ-
