spur issuing backwards from the hinder extremity on the outer side 

 is red-brown, a little bent, sharp-pointed, tapering, and thorn-like ; 

 its length is moderate, less than half the length of the joint, and it 

 points outwards. The palpal organs are of the usual form, and 

 almost encircled by a tapering, sharp-pointed spine, which issues from 

 near the middle of their outer side. 



The falces are moderately long and strong, but less so than in 

 many others of this genus ; they project forwards, but are straight 

 and do not diverge laterally from each other. 



The abdomen is not very large ; it is oval, and projects a little 

 over the base of the cephalothorax ; it is clothed with pale silky 

 hairs, and there are some darker prominent ones on the fore part of 

 the upper side. The spinners are yellow and rather short ; the second 

 joint of the superior pair is very short ; the inferior pair are much 

 the strongest. 



The female is a little larger than the male, but similar in colour and 

 other general characters. The genital aperture is short, transverse 

 oval, broken into at the middle of its fore side, and having a strongish 

 yellow-brown, corneous-looking margin. The legs of this sex are 

 also shorter and proportionally stronger than those of the male. 



An adult example of each sex were found in the collection received 

 from Bombay from Major Julian Hobson. 



Cheiracantihum isiacum, sp. n. (Plate LII. fig. 31.) 



Adult male, length 3-| lines ; adult female 4 lines. 



In general form and characters this Spider is very like the Euro- 

 pean species C. carnifex. 



The cephalothorax is not very convex above ; it is of a yellow 

 colour, clothed with short, fine, pale hairs. The ocular region is 

 strongly suffused with blackish brown ; and from each of the hind 

 central pair of eyes an indistinct tapering stripe of the same runs 

 backwards towards the junctional point of the thoracic segments ; 

 the normal grooves and indentations are well marked by converging 

 dusky stripes. 



The eyes are on black spots in the usual position ; they are rather 

 small, and do not differ greatly in size. The height of the clypeus is 

 no more than half the diameter of one of the fore central pair of eyes, 

 which are largest of the eight ; those of each row severally appeared 

 to be as nearly as possible equidistant from each other, the four central 

 eyes forming very nearly a square, the transverse, however, being 

 rather longer than the longitudinal diameter ; those of each lateral 

 pair are slightly obliquely placed on a tubercle, but not quite con- 

 tiguous to each other. 



The legs are long, moderately strong, their relative length being 

 1, 4, 2, 3 ; their colour is yellow, rather paler than the cephalo- 

 thorax, furnished with hairs of different length and strength, and 

 more than the ordinary number of spines ; the most characteristic of 

 these (in the male) are a single longitudinal row of about 12 or 13, 

 not very long, but tolerably strong, beneath the metatarsi of the 

 fourth pair, several others with the last one of this row forming a
