1872.] SPIDERS OF PALESTINE AND SYRIA. 273 



strongly curved ; the clypeus exceeds in height the length of the 

 space occupied by the four central eyes. 



Legs long, moderately strong ; relative length 4, 1, 2, 3 ; destitute 

 of spines, and with but very few hairs (perhaps denuded?) ; those on 

 the undersides of the tarsi are squamose. Each tarsus terminates 

 with three curved claws ; the inferior one very minute ; beneath 

 these are 2-3 straighter, opposed claws. 



Abdomen oval, very convex above ; spinners six, those of superior 

 pair three-jointed, the two terminal joints directed perpendicularly 

 upwards. 



This genus, which I have felt constrained to establish for the re- 

 ception of two Spiders found in Palestine and Syria, appears to con- 

 nect the genera Enyo and Agelena, but to be incapable of inclusion 

 in either of them ; it is also allied to the genus Lachesis. 



ClTH^ERON PRjEDONIUM, sp. uov. 



Female adult, length 2|-3| lines. 



The eephalothorax is of a dark yellow-brown colour, with a broad 

 lateral marginal band of a clear yellow ; the legs and palpi are yellow. 

 The eyes of the hind central pair are oval, oblique and near together 

 but not quite contiguous ; they are much further removed from the 

 laterals of the same row ; the interval between the fore centrals 

 (which are round and prominent) is greater than that between each 

 and the lateral on its side, with which it is almost but not quite 

 contiguous ; the interval between those of each lateral pair is rather 

 greater than that between either of the fore centrals and the hind 

 central opposite to it. The falces are not very long, but strong, 

 vertical, and conical in form, and prominent near their base in front ; 

 they are similar in colour to the eephalothorax ; the maxilla are 

 yellow, the labium brownish yellow, and the sternum yellow, with 

 strong marginal indentations between the basal joints of the legs. 



The abdomen is almost destitute of hairs ; it is of a uniform dark 

 maroon-brown colour above, and yellowish beneath, with a longitudi- 

 nally elongate yellow patch immediately above the spinners ; the 

 inferior spinners are blackish brown, and only half the length of 

 those of the superior pair, which are of a paler yellowish brown, three- 

 jointed, and turned upwards. 



An adult female was found under a stone on the Lebanon, and 

 another in a similar situation at Hasbeiya. 



The colours and markings of this Spider are very like those of 

 some species of Enyo, but its form and general structure are more 

 like those of Agelena and Tegenaria, while the maxillae are nearer 

 to those of Lachesis and Enyo ; and in the position of the eyes it 

 differs from either of the genera mentioned. 



Genus Agelena (Walck.). 

 Agelena syriaca, Koch, Die Arachn. x. p. 1 1 0, pi. 354. fig. 827. 



An adult male, and females adult and immature, of this handsome 

 Spider were found on the Lebanon and at Beirut.
