1872.] SPIDERS OF PALESTINE AND SYRIA. 271 



The cephalothorax is of a deep glossy black-brown colour, the 

 falees and sternum being similar, but the maxillae and labium much 

 lighter. 



The legs are long and slender, their relative length 4, 1, 2, 3; 

 they are of a dull yellow colour, except the femora, which are black- 

 brown, the tibiae also, in some examples, being slightly suffused 

 with the same. 



The eyes are placed in a position similar to that of the eyes in 

 the typical Enyos, — three in a short, curved, obliquely longitudinal 

 row on either side ; and transversely, between the two foremost eyes 

 of these rows, are two other eyes ; these latter, in the present species, 

 are much the largest of the eight, and are further from each other 

 than each is from the foremost eye of the other three on its side ; 

 these foremost eyes are next in size to the intermediate front ones, and 

 each of them is nearer to the intermediate one next to it than this 

 last is to the hindermost eye on its side, which is the smallest of 

 the eight. The height of the clypeus considerably exceeds half the 

 height of the facial space. 



The palpi are short, of a deep black-brown colour, except the 

 radial and cubital joints, which are dull yellow tinged with reddish 

 brown ; the former is the shortest, and is rather roundly prominent 

 on its outer side, where it is strongly and obtusely produced at its 

 extremity, this extremity being continued on its upperside by a 

 short, strong, pointed, corneous apophysis ; the digital joint is large, 

 oval, produced, and pointed at its extremity, which terminates in a 

 short curved black spine; the palpal organs are well developed and 

 prominent, with a strong, curved, corneous process at their fore ex- 

 tremity on the outer side, and another shorter, more obtuse, and 

 not curved, close to it on the inner side. 



The abdomen is oval, very convex above, and projects over the 

 base of the cephalothorax ; its upperside is black, and the under- 

 side is of a somewhat vinous black hue. The female resembles the 

 male in colour. 



Adults of both sexes were found under stones on the plains of the 

 Jordan. 



Enyo atriceps, sp. nov. 



Male adult, length 1^ line. 



This species is rather smaller than the preceding, and, though re- 

 sembling it in form and general structure, differs in various parti- 

 culars : the clypeus is not so high, being no more than half the 

 height of the facial space ; the cephalothorax is yellow, the caput 

 being of a deep reddish brown-black ; the falees are rather lighter 

 in colour ; the legs yellow, the femora and tibia? slightly suffused 

 with brown ; the palpi also are yellow ; the radial is shorter than the 

 cubital joint, and has a not very large blackish, red- brown, pointed, 

 corneous spine or apophysis in continuation of its outer extremity ; 

 the digital joint is not so large in proportion as that of E. luctuosa, 

 but, like that, its fore extremity terminates in a small curved black 

 spine : the palpal organs are well developed, but not very complex ;
