nearly in colour and markings. The abdomen, however, may be 

 distinguished (if this be a constant character) by the four white spots 

 of hairs on the hinder half of the upperside being stronger, elongated, 

 and the two on either side being almost confluent, forming nearly two 

 parallel longitudinal white bars ; the white transverse marginal bar on 

 the fore margin is also broader, straight, and in its length it only ex- 

 tends to the width of the abdomen. The structure of the palpi, how- 

 ever, readily distinguishes it from S.facetus: the humeral joint has 

 a longer prominence beneath its hinder extremity ; and the apophysis 

 at its fore extremity springs more from beneath than from the side 

 of the joint : it is also stronger, and is almost perpendicular, though 

 a little bent, and inclined backwards ; its extremity shows a kind of 

 transition from the simple to the bifid point, having a sort of notch 

 or indentation (looking like a small tubercle from some points of view) 

 near its point : this distinguishes it from any other species known to 

 me. The radial joint is shorter than the cubital, and has its outer 

 extremity produced into a tolerably strong blunt-pointed apophysis ; 

 and there is a small, sharp, black, tooth-like vertical spine beneath. 

 The digital joint is of a longish narrow oval form. The palpal organs 

 are well developed and greatly resemble those of many others of this 

 group, but are less globular and less prominent than those of the 

 preceding and some other species ; they have a small curved projec- 

 tion beneath at their base, and extend backwards on the inner side 

 in the form of a strong prominent blunt point. 



A single example was met with on low-growing plants on the plains 

 of the Jordan.

Of the ordinary general form and appearance of Spiders of this 

 group, the present species differs very decidedly in the structure of 

 the palpi. The white spots and fore marginal bar on the abdomen 

 are visible, but are less conspicuous than in either of the two last- 

 described species (possibly this may be due to the specimen having 

 been rubbed accidentally and so lost the white hairs which form those 

 markings). The legs are also darker — being black-brown, except the 

 tarsi, which are of a yellow-brown hue. The palpi have the humeral 

 joint short and tumid, and apparently without any basal tooth-like pro- 

 minence ; the characteristic apophysis from beneath its fore extremity 

 is long, strong, and produced into a blunt point much bent or hooked 

 inwards ; the general direction of this apophysis is nearly perpen- 

 dicular : the radial joint is very small ; it has an apparently cylin- 

 drical apophysis of a pale colour projecting forwards on its underside ; 

 and from near the base of this there projects outwards another, small, 

 curved, black, sharp-pointed one ; the digital joint is of ordinary form 

 and size, and has a broad band on its surface thickly clothed with 

 white squamose hairs. The palpal organs are of a more irregular 

 form than those of the last two species ; they have a strong blunt 

 horn-like projection from near their base on the inner side, a short
