smaller laterals, tlieir lower margins on a level with tlie 

 centres of the latter, the clypeus longer than an eye's 

 diameter. Posterior row of eyes strongly procurved, the 

 median eyes distinctly larger than the laterals and nearly ^ a 

 long diameter apart, their distance from the laterals also 

 decidedly exceeding their own length. 



Chelicera with only 2 distinct teeth in upper margin, that 

 corresponding to the proximal tooth of the other species 

 being quite obsolete, the lower margin without teeth. 



Legs scopulated much as in X. capetisis, sp. n.; meta- 

 tarsus I with two basal spines ; tibia I with an inferior row 

 of 3 spines. 



Pedipalps longer than in spoliator^ the tibia attenuated at 

 base, its dorsal side a little longer than the patella and angu- 

 larly produced at apex, the angle ending in a short slightly 

 out-turned spur ; outer distal edge of tibia obliquely truncated 

 and provided with a small, blunt, subcylindrical process, 

 which curves slightly upwards and inwards at apex; tarsus 

 rather broadly ovate, acuminate at apex ; palpal organ very 

 like that of spoliator but larger, the apical spine hook-like, 

 strongly curving inwards and upwards (PL XIV. fig. 31). 



? . — Chelicera sometimes with a minute proximal third 

 tooth. 



Tibia I with small internal scopula and an interior row of 

 2-3 inferior spines. 



Vulva-plate appearing in spirits as in PI. XIV. fig. 32, as 

 broad as long, allied in form to that of spoliator, but smaller, 

 the pair of cavities (light in the figure) separated by a 

 broader keel, which is shallowly grooved longitudinally, its 

 edges diverging anteriorly as well as posteriorly, each cavity 

 with a large dark-coloured convexity behind it, the median 

 groove of the keel deepened anteriorly but not posteriorly and 

 not reaching hind end of the vulva-plate. 



Length of trunk, S '^ , 9 mm. 



§ 2. Species in %vhich the lonr/itudinal f/roove of the vulva of the female is 

 provided anteriorly with ajlcxible towjue-like apiiendaije instead of a 

 pocket. (Spp. 10-l(i.) 



10. Xerophmus communis, sp. n. 

 (PI. XIV. figs. 33, 33 a, & 34.) 



Specimens. — (a) 1 ^ and 3 ? $ from the Willowmorc 

 District {E. H. L. Schoarz). 



c? ityP^)' — Very like X. capensis in form, colour, and in 

 the characters of the eyes, legs, and chelicera.
