ARANEIDEA. 21 



The cephalothorax is of ordinary form and of a brightish yellow-brown colour, clothed 

 with greyish and iridescent hairs and scales. 



The eyes are in two nearly concentric curved rows, like those of M. connexa and others, 

 the front row being the shortest. 



The legs are moderately long and tolerably strong ; their relative length is apparently 

 4, 1, 2, 3. They are similar in colour to the cephalothorax, the sides of the tibiae being 

 suffused a little with brown, and the tarsi have the appearance of being annulated with the 

 same colour. They are clothed with grey and iridescent hairs; the former disposed some- 

 what in longitudinal lines. 



The palpi are not very long; their colour is pale yellow; the cubital joint is shorter than 

 the radial, and the digital is of a long, narrow-pointed, oval form. Being immature, these 

 remarks on the palpi would, perhaps, not be strictly applicable to those of the adult spider, 

 though the proportions of the several joints would probably be the same as in the immature 

 state. 



Tliefalcen are tolerably long, strong, perpendicular, similar in colour to the cephalotho- 

 rax, and furnished with greyish hairs and dark bristles. 



The abdomen is of a dull yellow-brown hue, clothed thinly with iridescent, scaly hairs. 

 It has two parallel, transverse, slight constrictions near the middle of the upper side ; an in- 

 distinct longitudinal median brown marking, pointed at its posterior extremity, occupies the 

 fore-half of the upper side, followed towards the spinners by a longitudinal series of several 

 less distinct, transverse, curved, brown lines, the convexity of the curves directed forwards. 

 These markings would be probably invisible, except when in spirits of wine. 



Hab. Found on the route across the Pamir from Sirikol to Panja and back, April 22nd 

 to May 7th, 1874. 



Genus CLUBIONA, Latr. 



19. CLUBIONA DELETRIX, sp. n., PI. II, Fig. 14, <? . 



Adult male 2| lines : adult female, 3| lines. 



In colours and pattern this spider is very like Clubiona compta, C. L. Koch, and is still 

 more nearly allied to C. robusta, L. Koch (an Australian species). It is, however, smaller 

 than the latter, and in the palpi differs from both. 



The cephalothorax is of ordinary form, and its colour is brownish-yellow, tinged slightly 

 with reddish-brown towards the fore part of the caput. The normal indentations are dusky ; 

 the junction of the caput and the thoracic segments is marked with a short, fine, longitudinal 

 red-brown line, and the surface is thinly clothed with greyish-sandy pubescence. 



The eyes are of tolerable size, though not very unequal. They occupy the whole of the 

 width of the upper fore part of the caput, and, when seen from above and behind, are placed 

 in the usual two curved lines, the convexities of which are in opposite directions, and enclose 

 a somewhat oval area. The hinder row is much the longest, and the fore-central pair are 

 rather the largest of the eight. Those of the hind-central pair are considerably further from 

 each other than each is from the hind-lateral on its side, the interval somewhat exceeding two 

 diameters. Those of the fore-central pair are separated by about half a diameter, and are 

 rather farther from each other than each is from the fore-lateral on its side ; each fore-lateral 

 eye is separated from the hind-lateral next to it by an interval similar to that which separates
