 Walckenaera (id.).

Adults of both sexes of this widely dispersed Spider were found 

 at Jerusalem, the Lebanon, and Beirut.

This Spider is of the ordinary form, colour, and general structure. 



The cephalothorax rises gradually from the hinder part to the 

 caput, which is bluff and rounded, but not elevated, and the normal 

 grooves and furrows are not strongly marked ; it is glossy and of a 

 deep reddish-brown colour, with black margins. The eyes are in two 

 curved rows, of which the foremost is the shortest ; those of the 

 hind central pair are rather further from each other than each is 

 from the hind lateral on its side ; those of the fore central pair are 

 the smallest of the eight, and are contiguous to each other ; the eyes 

 of each lateral pair are seated obliquely on a tubercle. The height 

 of the clypeus is more than two thirds that of the facial space. The 

 legs are moderate in length and strength, and do not differ much ; 

 their relative length is 4, 1, 2, 3 ; and they are of a yellow colour 

 tinged with red. 



The palpi are short and darker-coloured than the legs ; the 

 radial and cubital joints are of about equal length, the former is the 

 least strong, and is produced rather on the outer side in front into 

 a longish, prominent, pointed apophysis, which is a little curved 

 downwards, and has a small, prominent sharp tooth beneath ; the 

 palpal organs are well developed and prominent, and have a circu- 

 larly coiled black filiform spine at their extremity. 



The abdomen is oval and projects over the base of the cephalo- 

 thorax ; it is glossy black and very sparingly clothed with hairs. 



Although closely allied to many European species, this one may 

 easily be distinguished by the form of the radial joints of the palpi, 

 taken in conjunction with its colours, the position of the eyes, and the 

 form of the cephalothorax ; it is perhaps most nearly allied to Neriene 

 herbiyruda (BL). 



Two adult males were found under a stone — one at Jerusalem, the 

 other on the Lebanon. 



Erigone inexpedibilis, sp. nov. 



Male adult, length -£$ of an inch. 



This is one of those puzzling species which, though presenting no 

 strongly marked and easily seized differential character is yet un- 

 doubtedly distinct from any other ; it is allied to E. rurestris 

 (Koch), and perhaps more nearly to Neriene (Linyphia) oblita 

 (Cambr.), and iV. pallipes (id.) ; but perceptible differences in the 

 relative position of the eyes, the armature of the legs, and the
