Neiv South African Scorpions. 25 



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

 anterior median edge 9^ ; width of hand 12i ; length of hand-back 

 10, of movable finger 17, of tail 56 ; width of first caudal segment 6, 

 of fifth caudal segment 4. 



Male (in alcohol). 



The male presents the following differential characters : 



Carapace as long as the first and second caudal segments 

 together. 



Cauda more robust. 



Terya. Whole surface densely and finely granular, the last seg- 

 ment coarsely granular at the sides and behind. 



Sterna minutely granular at the lateral borders in segments 1-4. 



Palps with all the segments much longer than in the female ; 

 hands long and narrow, with very long fingers ; length of hand-back 

 exceeding breadth of hand ; inner part of the upper surface of hand 

 flat, concave distally, weakly granular, nearly smooth in the middle, 

 with two weak secondary keels ; outer part of the upper surface 

 very weakly granular, nearly smooth ; inner edge of hand scarcely 

 denticulate. 



Operculum transversely oval, much broader than long, completely 

 cleft longitudinally. 



Pcctincs with 26-28 teeth, the scape rectangular at the base 

 behind and therefore toothed along its whole length. 



Besides these there are other differences which may be put down 

 to the specimens having possibly been captured in different localities. 

 The colour of the male, for instance, is much lighter, being brown with 

 a large black patch on the carapace on each side of the interocular 

 area, the palps reddish yellow with dark crests, the legs, vesicle, 

 interocular area, and the hands ochraceous ; further, the surfaces of 

 the humerus and brachium are much more sparsely granular, the 

 infero-lateral keels in segments 2 and 3 and the median keels in 

 segment 3 of cauda are crenulated. 



Measurements in Millimetres. Total length 109 ; greatest length 

 of carapace 16 ; width of carapace 15i ; distance of eyes from 

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

 10, of movable finger 25, of tail 65 ; width of first caudal segment 

 6^, of fifth caudal segment 4. 



Male, nearly adult (in alcohol). 



This specimen resembles the female in its coloration and in the 

 granulation of the surfaces of the humerus and brachium ; the 

 hands have the shape of those of the female but are narrower
