granular throughout, but without crests. Bushmanland (Cape Colony), 



German South-West Africa ^. P.brevimanus ^hon.). 



b\ Sides and under surface of 4th caudal segment either with crests or not 

 densely granular throughout. 



a?'. Middle lateral crest on 4th caudal segment strong and well developed, 

 coarsely granular throughout. 



a3. Superior crest in segment 5 more or less obliterated in the middle 

 of the segment by the dense granulation of the sides, which extends 

 here over the superior edges right up to the indistinct row of 4-6 low 

 rounded (rarely conical) granules representing the accessory crests. 

 Cephalothorax finely granular. (Upper surface of 1st caudal segment 

 very flat, as wide as long, with parallel sides, the shagreened area 

 occupying more than half the width of this surface. Hand never 

 thicker than the tibia of pedipalp.) 



a*. Upper surface of 2nd caudal segment with large shagreened 



area extending continuously from anterior to posterior margin. 



South-coast Divs. of Cape Colony .. la. P. capensis (H. &E.). 



h*. Upper surface of 2nd caudal segment with an oval shagreened 



area on its anterior half. North-east Divs. of Cape Colony. 



1/3. P. capensis YStv. frenchi, nov. 

 i3. Superior crest in segment 5 always distinct throughout the whole 

 length and very strong, sometimes slightly weaker in the middle of 

 the segment, flanked here on the inner side by a short acces- 

 sory crest of very coarse, generally sharply pointed or subspini- 

 form, sometimes blunt, tubercles. Cephalothorax rather coarsely 

 granular. 



a^. Segment 4 of tail always decidedly narrower than segment 1, 

 the tail more or less densely hairy. Congo, Benguela, 

 German South-West Africa, Bushmanland (Cape Colony.) 



6. P. villosus (Pet.), 

 fcs. Segment 4 of tail wider or at least not narrower than seg- 

 ment 1, tail sparsely hairy. 



a*". Caudal segments thickly granular at the sides and 

 below, especially in the posterior segments. Legs and 

 pedipalps dark brown to black. Transvaal. 



7. P. transvaalicus Pure. 

 6*. Caudal segments sparsely granular, the posterior seg- 

 ments below more thickly granular. Legs and pedipalps 



yellow. Bushmanland 8. P. schlechteri Pure. 



b'. Middle lateral crest on 4th caudal segment rudimentary, except 

 perhaps quite posteriorly. 



rt7. Tibia of pedipalps strongly prominent on anterior side, its length 

 along the upper side only about twice its width at base of large 

 anterior tooth. Cephalothorax about as long as wide. Bushman- 

 land (Cape Colony), German South-West Africa. 



4. P. IcEvifrons (Sim.). 

 bT. Tibia of pedipalps slender, its length 2^-3 times its width. Cephalo- 

 thorax much wider than long. 



a^. Upper surface of 1st caudal segment flattened, ]orojecting 

 step-like and then suddenly descending perpendicularly at the 

 anterior margin of the very broad shagreened area; 4th and 

 5th segments almost smooth or with a few granules below. 

 Calvinia and Clanwilliam Divs 2. P. calvus Pure.
