SECOND YARKAND MISSION. 



besides these there appear to be no more on any of the legs. Those of the third and fourth 

 pairs are much the shortest, the latter being a little longer than the third. 



The palpi are short, destitute of bristles and spines, and similar to the legs in colour. 



Thefalces are short, strong, sub-conical, rather projecting, and, excepting a small patch 

 bisected with a white line at their base near the outer side, of a white colour like the 

 clypeus. 



The maxilla and labium are of normal form, and similar to the legs in colour. 



The sternum is oval, hollow-truncate in front, and of a whitish hue. 



The abdomen is of good size, flattened above, projecting well over the base of the cephalo- 

 thorax, much broadest behind, where it is of a blunt-angular form on each side ; the form 

 of the upper side is therefore somewhat quadrangular, the fore part being a little roundly 

 truncated ; the sides, the fore part, and also the hinder extremity (which is abrupt) are 

 rugulose and marked with rows of small impressed points ; these are most apparent as a 

 margin to the fore part and sides. The five normal impressed points are visible on the fore 

 half of the upper side, and the whole of the abdomen is of a uniform white colour ; the spin- 

 ners are tolerably strong, very short, compact, and similar in colour to the legs. 



This spider is allied to, but quite distinct from, T. pugilis, Stoliczka, found in the 

 neighbourhood of Calcutta.

The whole of the fore part of this spider is a dull pale yellow. The cephalothorax 

 slightly tinged with brown, with a pale, somewhat triangular, patch at the occiput ; the 

 falces also being similarly tinged. The abdomen is white, a little suffused on the sides with 

 brownish-yellow, and with a narrow, median, brownish stripe on the fore half of the upper 

 side, emitting some lateral and posterior venose lines ; the usual five impressed spots are also 

 visible on the fore half of the upper side. 



The eyes are small, and differ but little in size, the fore-laterals being rather the largest ; 

 they are seated on white tubercles, in the form of a crescent, in two curved rows, the anterior 

 being the shorter and more curved ; the interval between those of the hind-central pair 

 is less than that between each and the hind-lateral eye on its side, while that between the 

 fore-centrals is slightly greater than that between each and the fore-lateral next to it. The 

 four central eyes form a square whose posterior side is a very little longer than its anterior, 

 and the interval between those of each lateral pair is less than that between the fore and 

 hind-central pairs. The height of the clypeus is less than half that of the facial space. 



The legs of the first and second pairs are long, moderately strong, and scarcely differing in 

 length ; those of the third and fourth pairs are much shorter, less strong, but also of nearly 

 equal length. Those of the second pair appear to be slightly the longest, and the third pair 

 slightly the shortest ; all are furnished with spines, of which there are two longitudinal 

 parallel rows beneath the metatarsi and tibiae of the two first pairs. The metatarsi and tarsi 

 are tinged with reddish yellow-brown.
