SECOND YARKAND MISSION. 



a pale, dull yellow colour, furnished with hairs ; and the metatarsi of the fourth pair have 

 calamistra on their upper sides. 



The palpi are rather short, slender, and similar to the legs in colour. 



The falces are moderate in length and strength ; they project a little forwards, and 

 (looked at from in front) are curved, the curves directed outwards, leaving a slightly oval 

 space between them ; their colour is dull brownish-yellow. 



The maxillae, labium, and sternum are of normal form, and rather paler in colour than 

 the falces. 



The abdomen is oval, not very convex above, but projects considerably over the hinder 

 part of the cephalothorax ; it is of a dull brownish-yellow colour, covered with cretaceous 

 white spots and small patches ; four small red-brown spots form nearly a square on the 

 middle of the upper side. In front of the ordinary spinners is a short, transverse, supernu- 

 merary mammillary organ, divided across the middle by a perceptible suture. 



The genital aperture is small and inconspicuous.

 30. CCELOTES TEGENARIOIDES, sp. n. 



Immature male (almost adult) : length 6| lines. 



This spider is exceedingly like a Tegenaria in its general form and appearance. 



The cephalothorax is round behind, but constricted laterally at the caput, and its 

 margins are depressed ; it is of a yellow-brown colour, and hairy, and has the normal indend- 

 ations well marked. 



The eyes are of moderate size, and not greatly different in that respect : they are placed 

 in two transverse curved rows ; the front row is the shorter and less curved, the con- 

 vexity of the curves being directed backwards. The eyes of the hind-central pair are a little 

 nearer to each other than each is to the hind-lateral eye on its side, being separated by rather 

 less than two diameters ; those of the fore-central pair are distinctly larger than those of the 

 hind-central ; they form a line slightly less, though of very nearly equal length, to that
