604 REV. O. P. CAMBRIDGE ON EGYPTIAN SPIDERS. [June 20, 



side longest. These four eyes are very large, the posterior ones being 

 rather less than the anteriors ; the two centrals of the front row are 

 larger than the laterals, and further from each other than from the 

 lateral nearest to it, the row itself being shorter than the middle row. 



The legs are long and moderately strong ; their relative length ap- 

 parently 4, 3, 1, 2, those of the fourth pair greatly exceeding the rest ; 

 they are of a straw-yellow colour ; the femora are marked on their 

 outer sides with a broken longitudinal stripe, and faintly annulated 

 with pale yellow-brown ; they are furnished with hairs and nume- 

 rous pale, but not very long nor strong spines ; and each tarsus ter- 

 minates with three pale claws, of which the superior pair are very 

 long and slightly curved, their hinder part finely pectinated ; the 

 inferior claw is exceedingly short, and bent almost perpendicularly 

 downwards; the extremities of the tarsi* (which are subdivided, 

 giving the legs eight joints instead of seven) are also furnished all 

 round with longish slender spines. 



The palpi are of moderate length ; their colour is yellow, and the 

 terminal claw long, slightly curved, and minutely pectinated. 



The falces are moderately long and strong ; they are of a yellow- 

 brown colour, with a dark brown longitudinal band in front, nearly 

 as wide as the falces, and they are furnished in front with numerous 

 hairs and long bristles. 



The maxilla and labium are of a dull brownish hue, tipped with 

 pale yellow. 



The sternum is nearly circular, and of a uniform pale straw-yel- 

 low colour. 



The abdomen is of a yellow colour, rather darker on the sides, 

 spotted and marked with brownish- black, and also with some spots, 

 lines, and patches of white pubescent hairs ; these latter give the 

 Spider a remarkable appearance, the darker markings being much 

 obscured by the general yellowish hairy clothing ; when examined 

 closely, however, and especially when in spirit of wine, the usual 

 characteristic markings become apparent enough. The normal longi- 

 tudinal macula on the fore half of the upperside is of a yellowish 

 brown hue, pointed behind, and with some black marginal spots ; and 

 the transverse chevrons are formed by more or less perfect blackish 

 lines ; the sides are spotted and marked with blackish. 



Three immature females of this Spider were found at the roots of 

 stunted herbage on the desert near Jebel y Silsilis, in Upper Egypt. 



Lycosa FIDELIS.

Lycosa galerita, L. Koch, ^Egypt. u. Abyss. Arachn. 1875, p. 69, 

 Taf. vii. fig. 1. 



The peculiar structure of the palpal organs of the male of this 

 Spider, well represented in Dr. Koch's figure (loc. cit. supra), with 

 some other striking characters, render its identity with L. galerita, 



* The subdivision of the tarsi of this and another allied Sinaitic species (L. 

 pralongipes, Cambr.) will probably necessitate the formation of a new genus for 

 their reception.
