Characters of a S specimen from Dergvliet : — 



Closely agreeing with the type of X, capensis and with 

 similar palpal organ, but differing in having the lateral 

 process of the tibia of the pedipalp strongly curved near apex, 

 much more strongly so than in X de/phinurus, sp. n., and 

 with a much larger inferior sinus (PI. XIV. fig. 22). 



In the other S c? the first tibia has tlnce inferior spines, 

 and in one case the first metatarsus has two pairs of basal 

 spines. 



The anterior row of eyes are also sliglitly less procurved 

 in this species than in the two preceding species, the lower 

 edges of the medians being slightly below the level of the 

 centres of the laterals. 



Length of trunk 8 mm. 



In the Museum are also 7 ? ? from the Cape Peninsula 

 belonging either to this or the foregoing species or to both, 

 and differing from the ? ? of X. capensis in that the median 

 groove of the vulva is continued anteriorly for some distance 

 beyond the rotund dark plate. It is noteworthy that none of 

 these females, nor the males of X delphinuras and interro- 

 gator, have been found on the northern slopes of Devil's Peak 

 and Table Mountain, which are, on the other hand, the only 

 localities in the Peninsula where the males and females of 

 X. cape7isis have been met with. 



4. Xerophceus flavescens, sp. u. (PI. XI V» fig. 23.) 



1 (J from Kondegat, near Clanwilliam {C. L. Leipoldt). 



Colour pale yellow, the chelicera and anterior part of 

 carapace reddish yellow ; the abdomen pallid, with dark hairs 

 and yellow scutellum. 



Canqjace narrower than usual; anterior median eyes large, 

 touching the much smaller lateral eyes, whose centres are, if 

 anything, a trifle above the level of the lower margins of the 

 medians, the clypeus subequal to a lateral eye in length ; 

 posterior median eyes a little larger than the laterals, about A 

 of a long diameter apart and about a diameter distant from 

 tlie lateral eyes. 



Legs longish, the first tibia with an inner row of two spines. 



Chelicera with 1 strong and 2 feeble superior teeth, tho 

 inferior tooth feeble or obsolete. 



Pedipalps. — Patella decidedly longer than the tibia, the 

 two segments together shorter than the narrow tarsus ; lateral 

 process of tibia long and narrow, bent somewhat downwards 

 from the base, but otherwise straight, reaching nearly to end 

 of tarsal organ and minutely inturued ut the pointed apex^
