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



hairs and bristles were wanting (probably rubbed off by accident) ; 

 but some strongish spines remained. The tarsal claws of the first 

 and second pairs have a single small tooth near their middle part 

 underneath ; on the other legs the claws were absent, probably 

 broken off by accident. 



The falces are short, rather strong, directed backwards, and of 

 a brownish orange-yellow colour. 



The abdomen is oval ; its colour is pale yellow, with two broad, 

 brown, nearly parallel, longitudinal, well-defined bands down the 

 centre of the upperside, and a less well-defined marginal stripe of 

 the same colour on each side ; taking the brown portions to be the 

 ground-colour, there are thus three strong longitudinal yellowish 

 stripes on the upperside — a straight one along the centre, and a 

 curved one on each side ; the underside has no markings, being of a 

 uniform pale yellow ; besides darker ones, the whole abdomen is 

 thinly clothed with greyish hairs. 



The adult male (length If line) resembles the female in colours 

 and markings ; the yellow stripes on the upperside of the cephalo- 

 thorax are clothed with white hairs ; and the ocular area has the 

 remains of a yellowish-grey pubescence. The palpi are short, their 

 colour is a dull brownish yellow, and they are furnished with white 

 and black hairs and bristles ; the cubital joint has a group of black 

 bristles near its extremity on the inner side ; the radial joint is 

 rather shorter than the cubital, and furnished thickly with dark 

 bristly hairs on the inner side ; the whole of the outer side is a little 

 produced, and apparently terminates with two small, blunt-pointed 

 apophyses, forming a small fork-like extremity (the hinder apophysis 

 being the least strong, and of a dark brown colour) ; the digital 

 joint is large, of an oval form, considerably exceeding in length that 

 of the radial and cubital joints together ; its colour is yellow-brown, 

 clothed with blackish bristly hairs, and tipped with grey ones ; the 

 palpal organs are large, and consist of a nearly globular pale brownish- 

 yellow corneous bulb, which extends backwards beneath the radial 

 joint. The tarsal claws of the fourth pair of legs are very slender, 

 and have several fine pectinations near and beneath the fore extremity ; 

 I was unable to observe those of the first and second pairs ; beneath 

 the terminal claws in both sexes is a small dark scopula. The central 

 yellow abdominal stripe in the male is much broader than the lateral 

 ones, and has some very fine yellow points, issuing obliquely on each 

 side, near its hinder extremity. These points represent the termi- 

 nations of the ordinary angular bars, or chevrons, here obsolete. 



An adult male, and two adult females were found in Upper Egypt. 

 It is a very distinct species, though allied to Attus lineatus, Koch, 

 and A. bresnieri, Luc. 



Attus memorabilis, sp. n. (Plate LX. fig. 1 10.) 



Adult male length 3 to 4| lines. 



Cephalothorax nearly double as long as broad, and of a flattened 

 form ; its colour is yellow-brown, and of a much deeper hue on the 

 hinder slope than on the sides, with a black margin slightly fringed
