very similar to that of X. crustosus, sp. n., l)ut straigliter ; 

 tarsal organ with the greater part of its underside white and 

 membranouSj with a long, outcurved, very fine filament 

 arising from a small dark mesial sclerite, the inner basal 

 angle produced into a short horn (PI. XIV. fig. 23). 

 Length 8 1 mm. 



5. Xerophams spiralifer, sp. n. 

 (PI. XIV. figs. 24 & 25.) 



Specimens. — 2 S S and 5 ? ? from Hanover, and a rj 

 and ? from Eierlontein, 8-9 miles we.st of Hanover (^S. G. 

 Cronwright Schreiner) . 



6 <S i^ypc^)- — Colour like that of X. capensi's, sp. n. 



Carapace shaped as in X. capensis. Anterior row of eyes 

 very strongly procurved, the medians large, very close to the 

 laterals, and with their inferior margins a little above the line 

 joining the centres of the latter ; clypeus equal to or very 

 slightly longer than a lateral eye ; posterior row of eyes only 

 slightly wider than the anterior row, strongly procurved, a 

 line joining the hind margins of the laterals cutting the 

 medians in front of their centres, the median eyes very large, 

 ovate, separated by not more than ^ of their long diameter 

 from one another and by about a diameter from the laterals ; 

 anterior and posterior lateral eyes slightly less than a poste- 

 rior eye's diameter apart. 



Chelicera and le(js as in capensisy but with fewer spines, 

 the first metatarsus having 1-2 basal spines and the first 

 tibia only 1 inferior spine. 



Fedipalps. — Tibia, viewed from above, turbinate, much 

 broader distally than long, its length, measured along inner 

 Uj)per edge, a little less than that of the patella ; its distal 

 part strongly produced laterally on outer side, the process 

 very 4hick and strong, truncated at apex and bearing on its 

 anterior side a slenderer acuminate process, which is directed 

 forwards almost at right angles to the other and ends in a 

 claw curving downwards ; tarsus large, strongly acuminate 

 and incurved distally, its length very much greater than that 

 of the patella and tibia together (inclusive of the |)rocess), 

 the distal portion projecting for more than ^ of tlie whole 

 length beyond the cavity containing the palpal organ ; palpal 

 organ complicated, bearing two long spines, viz. a white one 

 arising from the middle of the outer edge, thence running in 

 a sligiit curve forwards, and ending just before reaching the 

 a])ex of the tarsus, and an extremely long red spine, which 

 starts at anterior end, and, after describing a spiral ciuve and
