New South African Scorpions. 27 



except on the anterior median part ; segments 3-6 weakly keeled on 

 the posterior half, segment 7 with a low, broad, coarsely granulated 

 elevation on each side behind, but with no median elevation. 



Sterna smooth, segments 1-4 finely granular at the lateral 

 borders ; last segment smooth in the middle, distinctly keeled on 

 each side, the region between the keel and the lateral margin with 

 a depression posteriorly and a few large and small granules in front 

 of the depression. 



Gauda very wide and robust; the upper surface smooth, granular 

 only in segment 1 towards the sides ; upper crests granular, the 

 terminal tooth enlarged and spiniform in segments 2-4 ; upper 

 lateral crests granular, in segment 5 weak and present only on the 

 anterior half ; infero-lateral crests distinct and smooth in segment 1, 

 weakly crenulated in segment 2, granular in segments 3 and 4 ; 

 infero -median crests obsolete in segment 1, just visible in segment 

 2, weakly granular in segments 3 and 4 ; intercarinal spaces smooth, 

 if a few isolated granules be excepted ; basal segment quite smooth 

 below ; fifth segment robust, less than three times as long as broad, 

 its three inferior keels with strong, sharp teeth ; breadth of second 

 segment equalling its length along the upper median line ; vesicle 

 granular at the base below. 



Palps. All the crests of the humerus coarsely granular, upper 

 surface of humerus sparsely granular, anterior surface with very 

 coarse granules, inferior surface nearly smooth ; upper crest and 

 posterior surface of brachium coarsely granular ; hands hairy, 

 rather flat above and. coarsely granular ; finger-keel moderately 

 strong, granular throughout, secondary keels rather indistinct ; 

 hands moderately wide, the width considerably exceeding the length 

 of hand-back ; inner edge sharply denticulate. 



Leys with the lower edge of all the femora coarsely granular ; 

 tarsi of fourth leg with 1-2 external and 5 internal spines below, 

 and 4 on the external terminal lobe ; superior process shorter than 

 the lateral lobes. 



Opcrculum transversely oval, considerably broader than long, 

 completely cleft longitudinally. 



Pectines with 15-16 teeth, the scape rounded at the base behind 

 and free of teeth for about one-fourth of its length. 



Measurements in Millimetres. Total length 101 ; greatest length 

 of carapace 15i ; width of carapace 14 ; distance of eyes from 

 anterior median edge 10i ; width of hand 11 ; length of hand-back 

 9, of movable finger 16|, f tail 58 ; width of first caudal segment 

 74-, of fifth caudal segment 5. 



Locality. A single specimen labelled " Calvinia " (P. Percival).
