Scorpions from East Africa. 117 



xvii. pp. 314-315, April 1896, and related to 0. rugulosus, 

 from Ishiromo, Nyasaland, there described — a species "which 

 it resembles in having the trunk thickly granular above. 

 The two, however, maj be recognized as follows : — 



a. Median eves small, not elevated ; upperside of the 

 brachium more closely and less coarsely gi-anular, 

 the crest bounding it posteriorly weak ; the sculp- 

 tiu'ing of the upper surface of the hand finer, less 

 reticulated, more definitely granular ; upperside of 

 the fourth and fifth segments of the tail distinctly 

 granular ; none of the caudal segments -with dis- 

 tinctly carinate upper edges ; spine-armature of 

 tarsi 3 in front, 4 behind, with a bristle at the distal 

 angle ; pectinal teeth 6 in (j" ; legs piceous ruguhmis, Poc. 



h. Median eyes larger and elevated on a low tubercle ; 

 upperside of brachium covered with tuberculiform 

 granules, and bounded behind by a strong tubercular 

 keel ; upperside of hand covered with a pattern of 

 distinct ridges, formed by the anastomosis of gi-anu- 

 liform tubercles ; these tubercles distinct at the base 

 of the finger ; upperside of fourth and fifth caudal 

 segments not granular, the former segment as well 

 as the third with distinctly carinate and denticulate 

 upper edges ; spine-armature of tarsi 2 in front and 

 3 behind, with a bristle at the distal angle ; pectinal 

 teeth 10 ; legs ochraceous rugiceps, sp. n. 



Measurements in millimetres. — Total length 78 ; length of 

 carapace 11"5, of tail 40 ; width of hand 8'0 ; length of hand- 

 back 10, of movable digit 11. 



Lac. Kota Kota, west coast of Lake Nyasa (Universities' 

 Mission). A single male example was obtained. 



Had it not been for Kraepelin's statement to the effect 

 that the species from the Transvaal that was described as 

 0. IcBvipes is identical with 0. asper of Peters, I should without 

 hesitation have applied Peters's name to the form that was 

 described as new ; for not only is the name asper as appro- 

 priate for this form as it is inappropriate for Icevijies^ but, in 

 addition, the locality Tete, on the Zambesi, whence asper was 

 obtained, is twice the distance from the Transvaal that it is 

 from Kota Kota. 0. rugiceps^ though resembling 0. asper 

 {Iwvijjes) in the number of its pectinal teeth, differs in having 

 the terga granular, the hand and brachium also coarsely 

 sculptured, and the femora of the legs weakly granular 

 externally. In asper {Icevipes), moreover, the distal angle of 

 the tarsus is armed with a spine, not with a bristle as in 

 rugiceps.
