South African Arachnida. 169 



vesicle small, its width only about f that of the widest part of 

 segment 5. 



Segments 1-3 with 10, segment 4 with only 8, strong, coarsely 

 granular keels ; the infero-medial keels smooth or weakly erenular 

 in segment 1, more or less abbreviated posteriorly in segment 4 ; the 

 middle lateral crest in segment 4 rudimentary, except quite 

 posteriorly, very much weaker than the adjacent lateral crests of the 

 same segment ; fifth segment often slightly dilated inferiorly, the 

 infero-lateral crests with the teeth much enlarged and lobe-like in 

 the posterior half of the segment ; superior crests in segments 2-4 

 or 3-4 often with an enlarged but not sharply spiniform posterior 

 tooth, these crests in segment 4 perfectly regularly uniseriate 

 throughout, without trace of dislocation or duplication in the 

 middle ; the superior crests in segment 5 strong and distinct only in 

 the anterior third or half of the segment, the rounded, superior, 

 lateral edges being smooth or almost smooth posteriorly, but 

 •covered in the middle of the segment with low blunt granules, 

 which are continuous with and resemble those on the lateral 

 surfaces; there are no distinct inner accessory crests on the upper 

 surface. 



Upper surface of segment 1 not fiat but hollowed out from side to 

 side and deeply grooved mesially, not sharply demarcated anteriorly, 

 where it slopes downwards evenly and gradually in the middle, the 

 lateral parts of this surface with some coarse or fine granulation or 

 nearly smooth, the crests slightly converging posteriorly; the 

 shagreened area confined to the deep groove, narrow, occupying less 

 than ^ of the width of the upper surface, its length about 4 times 

 its width. Upper surface in segments 2-5 smooth or sparsely 

 granular laterally, deeply grooved mesially, the groove finely 

 granular anteriorly but smooth posteriorly in segments 2-4, smooth 

 in segment 5. 



Anterior segments rather weakly and for the most part sparsely 

 granular between the keels on the lateral and inferior surfaces, 

 segment 1 being almost smooth below ; segments 4-5 very densely 

 covered with low, coarse, rounded granules on the whole of the 

 lateral and inferior surfaces, the granulation even, especially on 

 lower surface of segment 5, where there are no traces of accessory 

 crests, the infero-median crest of this segment well developed, 

 uniseriate or indistinctly biseriate. 



Peclipali^s. — Femur finely granular above. Tibia slender, its 

 length in the 2 2f to nearly 3 times, in the ad. S' 2-|-2f times its 

 width ; the upper surface finely granular or nearly smooth (the latter
