 faint indication of a narrow pahsh wedge-shaped marking on the fore 



half of the upperside The spinners of the inferior pair are W 



strong, and cylindrical, and about three times the length of those of 



the superior pair. 



The female is rather larger than the male, but resembles it in 

 iorm, general structure, and colours. 



The form of the genital aperture is peculiar, but not remarkable 

 in its development ; it consists of two rather small, oblong-oval 

 opposed openings united at their fore part ; and beneath each of them 

 is a round red-brown, shining, corneous-looking, convex boss or spot 



An adult example of each sex was found by myself under stones 

 near Alexandria, in April 1864. 



Genus Drassus, Walck. 



Drassus nigrofemoratus, sp. n. (Plate LI. fig. 12.) 

 Adult male, length 2j lines. 



The cephalothorax of this very distinct species is of ordinary form • 

 its colour is a clear reddish yellow-brown, clothed with a few greyish 

 pubescent hairs on the hinder part, and some longish bristles directed 

 forwards m the ocular region ; the normal indentations are of a 

 deeper, duskier colour. 



The eyes are in two curved nearly parallel rows, the hinder one of 

 which is the longest. The eyes of the fore central pair are the largest 

 ot the eight ; they are separated from each other by about half of an 

 eye s diameter, and each is contiguous to the lateral of the same row 

 on its side ; those of the hinder row are equally separated from each 

 other ; and those of each lateral pair are wide apart ; in fact the 

 position of the eyes is more like that of Gnaphosa than the usual 

 type of Drassus. Dr. Koch seems to have been in doubt to which 

 of these genera to refer it ; but the form of the maxilla appears to 

 me to be decidedly that of Drassus. 



The legs are moderately long and rather strong ; they are of a 

 reddish-yellow colour, except the femora, which are quite black and 

 are furnished with a few hairs and spines ; each tarsus ends with two 

 curved pectinated claws, beneath which is a small claw-tuft or scopula 

 rhe palpi are short and strong, and of a dark yellowish-brown 

 colour The radial joint is, if any thing, rather shorter than the 

 cubital, and has its outer extremity continued in a long, tapering 

 curved, biunt-pomted apophysis, directed upwards and rather over 

 the hinder part of the digital joint; this apophvsis is more than 

 double the length of the joint itself; and extends to half the length 

 ot the digital joint ; this latter joint is of tolerable size and oval form • 

 and the palpal organs are well developed but compact, consisting of 

 several corneous spiues and processes.
