Mr. R. I. Pocock on a new Scorpion. 25 [ 



the lateral portions of the cephalothorax somewhat coarsely 

 granular ; two contiguous lateral eyes on each side. 



Tergites sparsely and bluntly, but somewhat coarsely 

 granular; the third, fourth, fifth, and sixth with a median 

 low smooth keel in front, and one low smooth keel on each 

 side, the seventh bearing on each side above a low eminence 

 terminating behind in a tubercle, and below a subtubercular 

 keel which also terminates behind in a large tubercle. 



Sternites smooth, anteriorly bisulcate. 



Tail mow than five times as long as the cephalothorax, taper- 

 ing gradually from the base to the posterior end of the fifth 

 segment ; the segments above excavated only in front and 

 close to the joint ; the rest of the upper surface flat, or nearly 

 so ; the first segment provided with ten keels, the second, 

 third, and fourth with eight keels, the fifth with seven keels ; 

 the superior keels on the first four well expressed and denti- 

 culate in the posterior half ; the superior lateral keels more 

 prominent and complete on these same segments, but less 

 denticulate than the superior keels ; the rest of the keeks 

 almost smooth, more or less uneven and subtubercular on the 

 first three segments, but on the fourth they are distinctly but 

 irregularly and bluntly dentate ; in the fifth segment the 

 superior keels are almost absent, being represented merely by 

 the edge formed by the slope of the lateral surface at right 

 angles to the upper surface, this edge is sparsely and bluntly 

 dentate, thesuperior lateral keels are well expressed and bluntly 

 and sparsely dentate ; the three inferior keels more strongly 

 developed than in the preceding segments, and strongly and 

 sparsely dentate ; the upper surface of this segment anteriorly 

 obsoletely bicostate. Vesicle. — Upper surface nearly fiat and 

 smooth in front, in its posterior two thirds convex from side 

 to side, and thickly and coarsely granular ; beneath it is flat 

 or slightly concave, and, as also are the sides, coarsely but 

 bluntly granular ; its greatest width is less than one third of 

 its length, and its greatest height or thickness less than one 

 fourth of its length ; anterior half of the aculeus subtuber- 

 cular below, the posterior half spiniform but short, and b.it 

 little curved. 



Palpi: humerus with upper surface sparsely but coarsely 

 granular, and bounded in front and behind by a low, bluntly 

 subdentate keel ; the anterior surface somewhat strongly 

 tubercular and granular ; the posterior surface smooth. 

 Brachium distinctly carinate above, behind, and below, the 

 keels smooth or subtubercular. Manus dilated, furnished 

 with ten complete, mostly granular or subtubercular, strong- 

 keels, the superior internal keel dentate ; the intercarpal
