South African Arachnida. 153 



in segment 4 very regular throughout, not interrupted in the middle ; 

 in segment 5 distinct and well developed only in the anterior fourth 

 of the segment (and occasionally again quite posteriorly), the rest of 

 the rounded, superior, outer edge more or less thickly covered with 

 irregularly arranged granules, the superior accessory crests repre- 

 sented, much as in capeiisis, by an irregular row of low rounded 

 granules, not distinctly demarcated from the rest. Inferior lateral 

 -crest in segment 5 with the teeth in the posterior half lobe-like and 

 much enlarged. 



Upper surface in anterior segments almost smooth or reticularly 

 -granular laterally, very finely and densely shagreened mesially, the 

 upper surface in the posterior segments smooth. Segment 1 

 flattened above, not grooved mesially, its upper surface considerably 

 longer than wide, with parallel crests, its length a little exceeding 

 twice the width of the shagreened area and about equal to the width 

 of the vesicle ; the shagreened area large, narrower than in capensis, 

 almost flat or very slightly concave, occupying in its widest part 

 almost or quite half the width of the upper surface, constricted 

 posteriorly, then widening again ; upper surface descending suddenly 

 (but not quite so perpendicularly as in capensis) along the anterior 

 edge of the shagreened area, which projects slightly forwards at the 

 middle. Segment 2 less flattened above, especially posteriorly, its 

 upper surface one-half longer than w^ide and about four times as long 

 as the width of the shagreened area, with parallel crests ; the 

 shagreened area moderately concave, especially anteriorly, con- 

 stricted posteriorly, then widened again, longer and narrower than 

 in segment 1, occupying in its widest part only about ^ of the width 

 of the upper surface ; upper surface descending nearly as abruptly 

 as in segment 1 in its mesial part along the anterior edge of the 

 shagreened area. Segments 3-5 deeply grooved mesially, the groove 

 finely granular in segment 3 and sometimes also in segment 4, but 

 smooth in segment 5. 



Upper part of lateral surface more or less finely granular in 

 segments 1-3, the rest of the lateral and the infei'ior siirface smooth 

 between the keels in these segments ; segment 4 granular posterior^, 

 but smooth anteriorly on the sides and below ; ventral surface of 

 segment 5 with a number of minute and some coarse conical 

 granules, which do not, however, form defined secondary crests, the 

 median crest strong, formed of a row of coarse conical granules ; 

 sides of segment 5 smooth along the middle, but with some large 

 .and small granules along the lower part.
