406 REV. O. P. CAMBRIDGE ON NEW DRASSIDES. [June 2, 



slightly angulate ; and there is a prominent point or spot of the same 

 hue about the middle of each side. The sides and underside of the 

 abdomen are similar to the upperside ; the sides, however, are 

 tinged forwards with reddish yellow-brown, and the underside has a 

 strongish, longitudinal, central band of a mouse-coloured brown. 



The spinners are rather short, those of the inferior pair much 

 the strongest, those of the superior pair exceeding them in length 

 by the very short second joint of the former. 



An adult female differed in being rather larger, paler-coloured, and 

 the abdomen less strongly marked. The falces also appeared to be 

 less projecting, and the legs are shorter and stronger. The genital 

 aperture is small, of a somewhat semilunar form, margined with red- 

 brown. 



An adult example of each sex was found by myself on low plants 

 near Cairo, in January 1864. 



Cheiracanthium inornatum, sp. n. (Plate LII. fig. 30.) 



Adult male, length 3| lines. 



The cephalothorax, legs, palpi, and sternum of this Spider are 

 yellow, the falces deep red-brown, the maxillae and labium being of 

 a lighter and duller red-brown hue. In general form and aspect it is 

 of the ordinary type. The cephalothorax is covered pretty densely 

 with fine, pale, silky hairs ; it is short, broad, slightly constricted 

 laterally at the caput, whose fore margin is squarely truncated ; and 

 the ocular region is somewhat suffused with reddish brown. 



The eyes are small, in the ordinary position, and occupy nearly the 

 whole width of the fore part of the caput. The clypeus is scarcely 

 equal to the diameter of one of the fore central eyes. The eyes 

 of the front row form a straight line, shorter than the hinder row, 

 which is curved, the curve directed backwards. The eyes of the 

 hind central pair are rather nearer to each other than each is to the 

 lateral of the same row on its side ; and the same relative position is 

 observable with respect to the eyes of the front row. The fore centrals 

 are the largest of the eight ; they form a line shorter than the hind 

 centrals, and each is separated from the hind central opposite to it by 

 an interval about equal to the diameter of the latter ; those of each 

 lateral pair are seated on a tubercle contiguous to each other 

 and in a slightly oblique line. 



The legs are long and slender ; their relative length is 1, 4, 2, 3 ; 

 they are furnished with hairs, and a few not very long nor strong 

 dark brown spines. Each tarsus ends with two claws and a com- 

 pact blackish claw-tuft. 



The palpi are not very long nor strong. The cubital joint is short ; 

 and the radial is rather more than double its length, cylindrical, and 

 its outer extremity terminates in a small, slightly tapering, straight, 

 red-brown apophysis, whose point is a little bent and somewhat un- 

 guiform. The radial joint is furnished with long prominent hairs, 

 principally on the underside. The digital joint is about equal in 

 length to the radial ; it is of ordinary form, hairy, and suffused with 

 brown, and considerably prominent on the outer side. The normal
