New South African Scorpions. 29 



step-like and then suddenly descending perpendicularly ; segments 

 3-5 convex from before backwards, but concave from side to side, 

 only the third being provided with a small patch of shagreened 

 surface in the middle ; first three caudal segments with ten keels, 

 the three upper pairs of keels weakly granular, but equally developed 

 in each segment (the uppermost parallel, not converging behind), 

 the two inferior pairs smooth in segment 1, weakly granular in 

 segment 2, and more coarsely granular in segment 3, these three 

 segments smooth and polished between the keels ; fourth caudal 

 segment with the uppermost crests weakly granular and all the 

 other crests practically or quite obsolete, its whole surface, with the 

 exception of a very few low remote granules smooth and polished ; 

 fifth caudal segment with the uppermost crests practically obsolete 

 and represented only by a few weak granules, the inferior lateral 

 crests obsolete anteriorly, represented posteriorly by 3 coarse 

 granules followed by 2 large teeth ; upper and lateral surfaces of fifth 

 segment smooth and polished, the inferior surface with a few 

 granules along the middle and 3-4 similar ones scattered on each 

 side, otherwise also smooth and polished ; vesicle with several rows 

 of granules on the lower surface. 



Palps. Superior and anterior surface of humerus roughened, with 

 parallel edges, bordered by a row of granules, the anterior surface 

 with two irregular series of coarse conical granules ; brachrum 

 scarcely roughened on the surface, the front edge with a few 

 granules distributed along its length and a large tooth at the base ; 

 front and hind edges of brachium nearly parallel, only slightly con- 

 verging distally ; hand long and slender, much thinner than the 

 brachium (when viewed from above) ; fingers long, incurved, the 

 movable one two and a half times as long as the hand-back. 



Legs with a row of granules along the upper and lower edges of 

 femora, otherwise almost smooth. 



Pectines shorter than the carapace, with 25-26 teeth, the pos- 

 terior basal angle of the scape produced into a broad prominent lobe. 

 Measurements in Millimetres. Total length 63 ; length of cara- 

 pace 7 ; width of carapace 8 ; distance of eyes from anterior edge 

 3 ; length of humerus (along upper side) 5i, of brachium 6-J, of 

 hand-back 3, of movable finger 7-J-; width of humerus If, of 

 brachium (at base of large anterior tooth) 2J, of hand If; length 

 of tail 38, of first caudal segment 5, of fifth 7 ; width of first caudal 

 segment 6, of fourth of, of fifth 5, of vesicle 4J ; height of first 

 caudal segment 4^-, of fifth 3-f, of vesicle 3. 



A single specimen collected by Mr. Max Schlechter in the Onder
