Ncu- South African Scorpions. 21 



granular and smooth only on the tubercle ; seventh segment with a 

 low, median, granular elevation, but scarcely showing a trace of 

 the lateral crests. 



Sterna smooth and polished, the last segment weakly granular, 

 except in front and at the sides where it is smooth ; anterior edge of 

 spiracles straight or nearly so, the posterior edge arched backwards, 

 the space between the edges thus considerably wider at the middle 

 than at the ends of the spiracle and occupied by a yellowish plate. 



Gaud a slender ; the upper crests granular, the terminal tooth in 

 segments 2-4 not or but slightly enlarged (in one specimen, however, 

 enlarged and spiniform) ; upper lateral crests granular, absent on 

 posterior half of the fifth segment ; infero-lateral and median keels 

 obsolete in segment 1, weakly granular in segments 2 and 3, granular 

 in segment 4, serrated in segment 5 ; upper surface granular in 

 segment 1, nearly smooth, with a few minute granules in segments 

 2-3 or 2-4, smooth in segment 5 ; intercarinal spaces more or less 

 granular, the granulation of the basal segment resembling that of 

 the last sternite ; vesicle sparsely granular at base below. 



Palps. All the crests of the humerus, its upper and under sur- 

 faces and the upper part of the anterior side coarsely granular ; 

 upper crest of brachium crenulated but not composed of a row of 

 large isolated granules, anterior lower edge coarsely granular, 

 posterior edge smooth ; posterior surface of brachium with numerous 

 smooth, often laterally sinuated ridges placed in rows to form 

 irregular longitudinal crests ; hands convex above, the whole upper 

 surface thickly covered with low, broad, rounded granules, which 

 often anastomose in the basal half ; finger-keel strong, for the 

 greater part smooth, showing a tendency to break up into granules 

 only at the base ; secondary keels very weak, defined by black 

 lines ; the hands wide, their strongly convex inner edge with blunt 

 granules. 



Legs with the lower edge of anterior femora weakly granular ; 

 tarsi of fourth pair of legs with only 3 spines on the external terminal 

 lobe and no external spines on the under side ; tarsi of the third and 

 fourth pair of legs with 8-9 internal spines on the terminal lobe and 

 the under side together, the fifth spine from the end being some- 

 times on the lobe, sometimes not ; tarsus of the third pair of legs 

 with 4 spines on the external lobe and 1 external spine on the under 

 side as well, which, however, is very small and occasionally absent ; 

 lateral lobes and the superior median process of equal length. 



Operculum cordate, broader than long, emarginate posteriorly, but 

 not cleft longitudinally. 



Pectincs with 9 or 10 teeth, rarely with as many as 11 or 12 ;
