same colour), whose angles are obsolete, the ends of the bars only re- 

 maining ; the sides are also marked with a few short irregular similarly 

 coloured lines and spots ; on either side of the longitudinal bar on 

 the fore half are three small but conspicuous reddish-brown spots, 

 forming a slightly curved line. The spinners are long and cylindrical; 

 those of the inferior pair slightly curved, longest, and strongest ; those 

 of the superior pair 2-jointed. 



The form of the cephalothorax is more elongate than in Cheiracan- 

 thium generally ; it is oval, with the lateral constriction at the caput 

 very slight, and the fore part moderately narrow ; the normal grooves 

 and indentations are marked by dusky converging lines. 



The eyes are of moderate size, in two transverse curved rows, the 

 eyes of each of which respectively are equidistant from each other ; 

 the four central eyes form a quadrangular figure, whose hinder side is 

 rather the longest ; the eyes of each lateral pair are placed obliquely 

 but are not contiguous to each other. The clypeus appears to be 

 about equal in height to the diameter of one of the fore central eyes. 



The legs are moderately long and tolerably strong ; their relative 

 length is 1, 4, 2, 3 ; and the genual joints are longer than usual ; they 

 are furnished very sparingly with hairs and a few spines ; each tar- 

 sus ends with two curved pectinated claws, beneath which is a very 

 small claw-tuft. 



The palpi are not very long, but tolerably strong. The cubital and 

 radial joints are about equal in length ; the latter is bent and has 

 at its extremity on the outer side a rather prominent, slightly 

 curved, tapering, sharp-pointed, red-brown, spine-like apophysis ; 

 and near the extremity on the inner side are two spines, one nearly 

 upright, the other shorter but bent and directed forwards. The di- 

 gital joint is dark yellow-brown, oval, pointed before, but not drawn 

 out as in other species of this genus ; it is about equal to, or perhaps 

 a little longer than the radial joint ; the normal spur from the hinder 

 part is obsolete, represented only by a slight prominence. The palpal 

 organs consist of a principal oval lobe broken up at its fore part into 

 several corneous processes, among which is a strongish one, somewhat 

 in the form of an S crook. 



The falces are moderately long, tolerably strong, projecting and 

 prominent towards their base in front. 



The maxilla are strong, of an oblong form, rather broadest at 

 their extremities, straight but slightly inclined to the labium, which 

 is half the length of the maxillae, and of a short, oblong-oval form. 



The sternum is of the ordinary heart-shape, with a slight emi- 

 nence opposite the articulation of each pair of legs. 



A single adult male of this species was found by myself near Alex- 

 andria (Egypt), in April 1864. 



Cheiracanthium equestre, sp. n. (Plate LI I. fig. 29.) 



Adult male, length rather more than 2\ lines. 



The cephalothorax of this species is of a yellowish colour ; it is 

 longer in proportion to its breadth than in many others of the genus, 

 and the lateral constrictions of the caput are stronger, the caput
