however, by having the external surface of the femora of the 

 anal legs granular, only six or seven pectinal teeth, and the 

 high vesicle. 



Measurements in millimetres. — Total length 71; length of 

 carapace 11, of tail 33 ; height of the vesicle 3*3; width of 

 first caudal segment 2*5 ; length of hand-back 9, of movable 

 digit 10 ; width of hand 7*8. 



hoc. Basutoland (R. C. Wroughton). 



Under 0. vnlidus I formerly (Ann. & Mag. Nat. Hist. (6) 

 xii. p. 318) included more than one species. 0. asiaticus, 

 Keys., for example, which occurs at Port Elizabeth, is distinct 

 from the Natal species which I now think is validus, 

 Thorell; 0. capensis, Thor., is also probably distinct, though 

 unknown to me. 



Genus Cheloctonus, Poc. 

 Cheloctonus anthracinus, sp. n. 



Allied to C. crassimanus, Poc, but black all over, except 

 the vesicle, which is ferruginous. The upperside of the 

 brachium and hand much more coarsely sculptured, orna- 

 mented with thick smooth ridges and scarcely visibly punc- 

 tured. In crassimanus the integument of the hand and 

 brachium is densely punctured, the sculpturing forms a much 

 closer and finer reticulation of ridges, and the inner portion 

 of the upper surface of the hand is distinctly granular. 



Measurements in millimetres. — Total length 54 ; length of 

 carapace 7"2, of tail 26, of hand-back 5 5, of movable 

 digit 7-2 ; width of hand 7. 



Loc. Griqualand West (J.ff. Darling). 



Genus HemiSCOKPIUS, Pet.* 

 Hemiscorpius arabicus, sp. n. 



Hemiscorpius lepturus, Pet., Pocock, Journ. Linn. Soc, Zool. xxv. 

 (1896) p. 316 (not lepturus, Pet.). 



Colour. Dull olive-yellow on the trunk ; vesicle clear 

 yellow ; legs testaceous ; chelae reddish yellow ; digits black, 

 with pale tips. 



Carapace longer than the first and second and than the 



* Mon. Ak. Wiss. Berlin, April 1861, p. 426. Peters subsequently cited 

 this genus as Hemiseorpion (op. cit. p. 511, May 1861). He described it 

 originally, however, as Hemiscorpius, although in the editorial intro- 

 duction to his paper, for which the editur and not Peters must be held 

 responsible, it appears as Hemiscorpion. It is curious that Kraepelin in 

 his 'Revision,' does not cite the original reference to the genus nor 

 Peters's admirable figure of the species.
