ARANEIDEA. 11 



on the fore-half of the upper side, where also four small brown spots form a square, whose 

 fore-side is rather the shortest ; the two hinder ones of these spots are in a line with the 

 point of the oblong marking ; the spinners- are rather long and strong, those of the inferior 

 pair being much the strongest and nearly double the length of the superior pair ; their colour 

 is brownish-yellow. 



This species is nearly allied to D. lapidicolens, Walck. 



nab. Hills between Sirikol and Aktalla, between the 8th and 13th of May 1874, and 

 on the road across the Pamir from Sirikol to Panja and back between April the 22nd and 

 May the 7th, 1874. 



9. DRASSUS DISPTJLSUS, sp. n., PL I, Fig. 8, g . 



Adult male : length 4| lines ; adult female, 5 lines. 



This spider, which is allied to D. lapidicolens, Walck., is very similar in its general form 

 structure, and appearance to D. interpolator ; it is, however, of a generally brighter hue. 



The cephalothorax is of a brownish-yellow colour, the normal indentations of a darker 

 hue ; the thoracic indentation being deep red-brown. The falces, maxilla, and labium are 

 reddish yellow-brown, the legs and sternum yellow, and the abdomen pale straw-yellow. The 

 cephalothorax is covered with greyish-yellow pubescence. 



The eyes are of moderate size, and not very unequal; they are in the usual position, 

 but the hinder row is not so much curved as in D. interpolator ; those of its central pair are 

 much nearer together than each is to the lateral of the same row on its side ; they are of an 

 oval form, placed very slightly obliquely and less than their longest diameter's distance from 

 each other ; those of the fore-central pair are further from each other than each is from the 

 lateral eye on its side, with which it is nearly, but not quite, in contact. The interval 

 between the fore-centrals is nearly about a diameter, and these eyes form a line rather longer 

 than that formed by those of the hind-central pair : those of each lateral pair are obliquely 

 placed, and are separated by an interval equal to the diameter of the foremost of them. 



The legs are rather long and slender, armed with longish spines, especially on the tibiae 

 and metatarsi of those of the two hinder pairs ; their relative length is 4, 1, 2, 3. Beneath the 

 two terminal claws of each tarsus is a small claw-tuft, with a scopula of blackish hairs along 

 the under sides of the tarsi, and of the first and second pairs of the metatarsi also. 



The palpi ( <? ) are rather short, the humeral and cubital joints are yellow, the radial 

 and digital joints suffused with yellow-brown, the latter being the darkest : the cubital and 

 radial joints are of equal length ; the latter expands a little at its anterior extremity, which 

 is produced (on the outer side) into a rather long, not very strong, slightly tapering apophy- 

 sis : this apophysis is nearly straight, but a little divergent from the digital joint, and its 

 extreme point is bifid ; there is also another shorter, angular prominence, or projection, at 

 the extremity of this joint, on the inner side. The digital joint is elongate-oval, equal in 

 length to the cubital and radial joints together. The palpal organs are simple but rather 

 prominent, their fore-extremity has a somewhat truncated appearance, and is broken up into 

 several corneous spines and processes. 



The falces are neither very long nor strong ; they are straight, and their direction is but 

 a little forwards. 



The maxilla and labium are similar in form to those of D. interpolator. 



The abdomen is of an elongate-oval form, rather truncated before ; it is very thinly
