SECOND YARKAND 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, hut 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 cubita 
joints together ; the palpal organs consist (so far as I could ascertain) of a simple, large, ovab 
convex lobe, apparently surrounded on its outer margins by a long, slender, filiform spine. 
The falces are strong and massive, a little projecting, roundly prominent near their base 
in front, and similar in colour to the cephalothorax. 
The maxillae 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 upp e3 j 
side has an elongate longitudinal marking of a deeper rusty red-brown than the rest, bisectec 
along its length by a fine, hut not very clear, yellowish line. The spinners are pale ycllo' v ' 
ish, of moderate size and length, those of the inferior pair being a little the stoutest. 
The female is rather larger, hut resembles the male in colours and markings, excep 
that the abdomen is less marked and streaked with rusty red; the form of the genital »P er * 
ture, which is quite small, is characteristic.

The form of the cephalothorax is of the ordinary type ; in fact, this spider in its g enel 
form, structure, and appearance, bears a close resemblance to Chiracanthium nutrix, G- 
nifex, and other allied species. It must, however, be premised that, the spider now descri ^ 
having been preserved in spirit of wine for a long time, its present colours are in all P r °^^ 
bility very unlike those of the living spider, in which perhaps the abdomen may have 
of a more or less green hue. ubes- 
The cephalothorax is of a dull brownish-yellow colour clothed with sandy-grey P 
cence ; the normal indentations are distinct, and a largish depression surrounds the 1 
junction. ^ ^ £ ore 
The eyes are rather small, in two transverse rows occupying the whole width of ■. ^ r ds ;
