136 MR, R. 1. POCOCK ON THE SCORPIONS [Mat. 18, 



Tail robust, almost parallel-sided ; conspicuously sulcate above ; 

 the upper surface at least of the four anterior segments minutely 

 granular and furnished in addition on each side with a series of 

 larger granules parallel to the keels ; the first and second segments 

 with the four superior keels strongly developed, granular at the sides, 

 almost smooth, not carinate, but deeply and sparsely punctured below; 

 the third segment also with the superior keels well developed, but 

 more granular at the sides and more closely punctured below, also 

 bearing a faint indication of the inferior lateral keels ; fourth seg- 

 ment with only the superior keel well developed, the rest almost 

 obsolete ; the sides and under surface thickly and coarsely granular 

 and punctate ; the fifth segment very coarsely and thickly granular 

 below and at the sides, the superior keel obsolete behind ; the upper 

 surface hollowed behind. Vesicle ovate, smooth above, granular 

 below, except for two smooth tracts which run backwards from the 

 base of the acnleus ; the rest granular and setose ; a large spine 

 beneath the aculeus, which is of the ordinary form. 



Palpi. Upper surface of humerus minutely granular, the anterior 

 and posterior keel strongly developed and coarsely granular ; anterior 

 surface subtubercular and bounded below by a row of granules ; 

 inferior surface almost smooth, feebly granular only in front and 

 proximallv ; posterior surface furnished with a subtubercular keel ; 

 the whole segment sparselj' setose : bracMum sparsely setose ; its 

 anterior surface granular and subtubercular ; its upper surface 

 behind, its posterior and inferior surfaces smooth and rounded 

 and punctured : manus hairy, with a tubercle at the base of 

 the dactylion the anterior surface, smooth, rounded, neither granular 

 nor costate : dactyli very hairy, moderately long and curved, in 

 contact throughout, neither sinuate nor lobate ; the arrangement of 

 denticles is much the same as in the preceding species, i. e. in the 

 dij'tal third, owing to the enlargement and partial isolation of the 

 distally apical tooth of the separate rows which constitute the median 

 series, the inner series is composed in this part of the digit of pairs of 

 teeth. 



Legs vi\ih femora anteriorly granular, but only subcarinate above ; 

 patellce almost wholly smooth, the fourth pair only slightly granular ; 

 tihi(B of two posterior pairs armed beneath with a spur ; coxcb 

 smooth. 



Pectines projecting beyond the edge of the fourth coxse ; furnished 

 with 23 or 24 teeth, whereof the basal tooth is enormously enlarged 

 but not longer than the rest. 



Stigmata slit-like. 



cJ . Differs from the $ in having the tail much longer {cf. measure- 

 ments), in having the hand longer and armed with a larger and 

 sharper tooth, and in having the basal pectinal tooth like the rest of 

 the series.
