being thus rather narrower and more drawn out ; the normal inden- 

 tations are not very strong, but are well indicated by converging 

 dusky radii. 



The eyes are rather larger than usual, but in the ordinary position, 

 and seated on black spots, and form two transverse curved rows, 

 occupying the entire width of the fore part of the caput ; the curves 

 are directed away from each other, that of the hinder row being the 

 strongest. The clypeus is almost obsolete, the edge of the fore cen- 

 tral eyes almost touching the fore margin of the caput. The eyes of 

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

 the hind lateral on its side ; and a similar relative position is observ- 

 able in regard to the eyes of the front row. The interval between 

 each fore central eye and the hind central nearest to it is less than 

 the diameter of the latter ; the fore centrals are largest of the eight ; 

 the eyes of each lateral pair are seated obliquely on a tubercle very 

 near but not contiguous to each other. 



The legs are rather long and moderately strong ; their relative 

 length is 1, 4, 2, 3 ; they are of a slightly lighter-coloured yellow 

 than the cephalothorax, furnished sparingly with hairs and a very 

 few spines ; each tarsus ends with two claws, beneath which is a 

 compact blackish claw-tuft. 



The palpi are not very long, but moderately strong. The radial 

 joint is scarcely double the length of the cubital ; it is cylindrical, and 

 has its outer fore extremity prolonged into a tolerably strong, tapering, 

 sharp-pointed, bicurved apophysis, of a dark reddish-brown colour, 

 equal to half the joint in length ; the inner side of the fore extremity 

 also has a small prominence or apophysis. The digital joint is rather 

 large, and equal in length to the radial and cubital joints together ; 

 it is of a dark blackish yellow-brown colour, prominent at the 

 middle of the outer side, and hairy ; the fore part is produced and 

 tapering, like that of nearly all the known species of Cheiracanthium, 

 though not so elongated as in some others. The normal spur directed 

 backwards from the outer side of the hinder extremity is strongly 

 bent downwards and directed outwards ; it contracts rather abruptly 

 towards its extremity, terminating in a fine, sharp-pointed, red-brown, 

 corneous-looking spine. The palpal organs are of the ordinary form 

 and simple structure, and are almost encircled by a slender, tapering, 

 sharp-pointed spine, which issues from near the middle of their outer 

 side. 



The falces are neither very long nor strong; they are straight, 

 projecting, not divergent, and of a yellow-brown colour. The maxillae 

 and labium are of normal form and structure and rather lighter- 

 coloured than the falces. 



The sternum is pale yellow and very glossy. 



The abdomen is oval, considerably convex before, and rather 

 sloping down towards the hinder part ; its fore part projects a good 

 deal over the base of the cephalothorax ; its upper surface is yellowish 

 white, as if covered with confluent cretaceous-looking spots. On the 

 fore half of the upperside is the ordinary elongate macula of a dull 

 dark mouse- coloured brown hue; the sides of this macula are
