24 SECOND YAEKAND MISSION. 



constriction of the caput is very slight ; it is glossy, and of a brownish-yellow colour, rather 

 deepening towards the fore margin. The clypeus is almost obsolete. 



The eyes are small, not greatly differing in size ; they are in the usual position, and occupy 

 the whole width of the forepart of the caput ; the two rows are rather nearer together than 

 in the two former species, but the relative position of the various eyes is very similar. The 

 interval between those of the hind-central pair is double that between each and the hind- 

 lateral eye on its side. 



The legs are moderate in length and strength ; their colour is yellow, and they are fur- 

 nished with hairs and a few spines, but the latter had been mostly broken off. 



The palpi are short, and their colour is yellow, excepting the digital joint, which is 

 brown ; the radial is rather shorter than the cubital joint and has a moderate-sized, red- 

 brown, pointed, tapering, slightly curved apophysis at its extremity on the outer side. The 

 digital joint is oval, of moderate size, and slightly exceeds in length the radial and cubital 

 joints together ; the palpal organs consist (so far as I could ascertain) of a simple, large, oval> 

 convex lobe, apparently surrounded on its outer margins by a long, slender, filiform spine. 



The f alces are strong and massive, a little projecting, roundly prominent near their base 

 in front, and similar in colour to the cephalothorax. 



The maxillce and labium are of normal form and similar in colour to the cephalothorax. 



The sternum is oval, pointed at its hinder extremity, and its colour is yellow. 



The abdomen is rather small, and its form oval ; its colour is a dull yellowish, thickly 

 mottled and streaked above, and on the sides, with rusty red. The fore half of the upper 

 side has an elongate longitudinal marking of a deeper rusty red-brown than the rest, bisected 

 along its length by a fine, but not very clear, yellowish line. The spinners are pale yellow- 

 ish, of moderate size and length, those of the inferior pair being a little the stoutest. 



The female is rather larger, but resembles the male in colours and markings, except 

 that the abdomen is less marked and streaked with rusty red ; the form of the genital aper- 

 ture, which is quite small, is characteristic.

22. CHIRAC AN THITJM ADJACENS, sp. n., PI. II, Fig. 17, <? . 



Adult male : length rather over 3 lines. 



The form of the cephalothorax is of the ordinary type ; in fact, this spider in its general 

 form, structure, and appearance, bears a close resemblance to Chiracanthium nutrix, C. car- 

 nifex, and other allied species. It must, however, be premised that, the spider now described 

 having been preserved in spirit of wine for a long time, its present colours are in all proba- 

 bility very unlike those of the living spider, in which perhaps the abdomen may have been 

 of a more or less green hue. 



The cephalothorax is of a dull brownish-yellow colour clothed with sandy-grey pubes- 

 cence ; the normal indentations are distinct, and a largish depression surrounds the thoracic 

 junction. 



The eyes are rather small, in two transverse rows occupying the whole width of the fore 

 part of the caput ; the hinder row is curved, the convexity of the curve directed backwards ; 

 the front row is shortest and nearly straight, those of the hind-central pair are rather nearer 

 together than each is to the hind-lateral eye on its side, the distance between these being
