from tliera, tlieir lower marg-ins, if anything, a trifle below 

 the level of the centres of the latter, the clypeus considerably 

 longer than a lateral eye's diameter; posterior row of eyes 

 considerably wider than the anterior row and moderately 

 procurved, a line joining the hind margins of the laterals 

 passing slightly in front of the centres of the medians ; the 

 latter oval, a little larger than the laterals, their distance 

 apart about h a long diameter (more or less), their distance 

 from the laterals slightly exceeding a long diameter ; the 

 lateral eyes on each side about a diameter or slightly less 

 apart. 



Chelicera with 3 well-developed teeth on tlie superior 

 margin, the middle one being very large, tlie inferior margin 

 with a strong tooth. 



L^gs with the scopuloj and spines as in X. capensis, sp. n., 

 but the first tibia with only 1-2 inferior spines and occa- 

 sionally witli an internal spine in addition, but no basal spine, 

 Pedij)al]js longish ; the tibia cylindrical, longish, its length 

 (exclusive of tlie process) a little exceeding that of the 

 patella, its upper surface with a strong mesial spine, its lateral 

 process slender, acuminate, straight or slightly upturned 

 distally when viewed from the side, but slightly curved when 

 viewed from below and simply pointed ; tarsus small and 

 narrow, acuminate, tlie apex obtuse, palpal organ narrower 

 than the tarsus, appearing in spirits as in PI. XIV. fig. 27, 

 the apical spine very slender, out-turned. 



? $ . — JB^es more spaced out than is generally the case in 

 the male, the posterior medians often separated by a space 

 only slightly less than a long diameter and generally about 

 1^-1 1 diameters distant from a lateral eye, the posterior 

 medians also often scarcely larger than the laterals. 



First tibia with the distal scopula distinct and occasionally 

 with three inferior spines below in the distal half, th« basal 

 spine always absent. 



Vulva appearing in spirits as in PI. XIV. fig. 28 ; the 

 posterior part with a pair of blackish somewhat reniform 

 convexities, each with an intensely black cavity on the medial 

 side, and separated by a long median keel, Avhich is strongly 

 convex from behind to in front and sharply marked off on 

 each side ; in front of the anterior end of the keel is a small 

 pocket opening posteriorly and visible through the integu- 

 ment as a brown half-moon.
