Mr. S. Hirst oi new Scorpions. 463 



anteriorly in each tergite. First and second tergites with 

 traces of the median keel only. Tergites 3-6 with three 

 rather short granular keels, which are restricted to the poste- 

 rior half of the segments ; the median one is much the 

 strongest and is continued forwards by a dark line. 



Sfernites smooih and shining except for the last one, which 

 is finely granular and has four weak granular keels, the outer 

 pair being indistinct. 



Tail. — First segment of tail the widest, the last two 

 segments slightly narrowed. Caudal keels finely granula?-. 

 In segments 1-3 they are ten in number; the superior and 

 the two uppermost lateral, keels are weak in these segments, 

 especially in the third,, the superior being weaker in the 

 second and third segments than in the first; median ventral 

 keels of second and third segments strong. In the fourth 

 segment the superior keel is practically absent, weak traces 

 of the anterior part of it alone remaining, and the superior 

 lateial has almost disappeared also;, the median lateral and 

 the median ventral keels are absent. Only the inferior 

 lateral keels are present in the fifth caudal segment, and their 

 end granules are enlarged. Intercarinal spaces finely 

 granular ; the granulation in the middle of the ventral surface 

 of the fourth segment is slightly coarser than tliat of the 

 rest of the surface ; a number of the granules of the distal 

 end of the ventral surface of the fifth caudal segment are 

 enlarged, and two longitudinal, almost keel-like series of 

 granules, which converge at the proximal end of the segment, 

 run down the centre of it. Upper surface of the segments of 

 the tail rather weakly excavated and either quite smooth or 

 with a few scattered granules only ; a shallow dorsal depres- 

 sion is present just before the end of the fifth segment. 

 Vesicle very similar in shape to that of iV. andersoni ; it is of 

 fairly large size, but narrower than the last caudal segment, 

 and is smooth, shining, and punctured ; a low and incon- 

 spicuous tubercle is present at some distance below the sting. 

 Chela stout. Its femur is smooth below, but the dorsal 

 surface is furnished with fine granules and has a weak 

 granular keel posteriorly and traces of an anterior keel. 

 Tibia much broader than the femur and than the hand 

 and devoid of granulation. Hand smooth and without any 

 granules ; its fingers rather short, the movable one being 

 about twice the length of the hand-back and furnished with 

 five(?) w^eak series of granules (which are difficult to make 

 out) ; with the exception of the proximal series each of them 

 has a couple of outer granules at the proximal end and a 

 single large granule on the inner side..
