146 Annals of the South African Museum. 



absent from the specimen correctly described by Pocock as the male 

 of granifrons, I may here mention that the scape of the pectines is 

 rounded at the base and free of teeth in the male for about J, in the 

 ? for about -? of its length. 



The following remarks are based on a careful examination of 

 considerably over a hundred adult specimens from various localities. 



The finger-keel is composed of coarse granules, by which this 

 species is generally readily distinguishable from its allies 0. leipoldti, 

 fuscipes, and capensis. Occasionally, although rarely, the granules 

 in the distal part fuse to a short smooth ridge, which, however, 

 never occupies more than ^ of the length of the keel. The granula- 

 tion on the last abdominal sternite of the $? is weak, but never quite 

 absent, and may extend over nearly the whole segment or be reduced 

 to a few mesial granules. The superior process of the tarsi is very 

 rarely almost as long as the lateral lobes, being generally much 

 shorter than these. The number of the spines on the external lobe 

 of the posterior tarsi is remarkably constant. I found four such 

 spines on one of the legs in a single specimen ; in every other case 

 there were only three. The posterior half of the interocular area of 

 the carapace is generally nearly smooth, but in a few specimens (of 

 unknown locality) with very strong granulation the whole of this 

 area was coarsely granular. The maxillary processes are often 

 entirely infuscated.

The Museum has recently received an additional number of well- 

 preserved specimens (in formaline) kindly collected by Mr. B. 

 Pattison at Clanwilliam (alt. 245 ft.). The species lives in burrows 

 alongside of the main street of the village. The total number of 

 adult specimens, which I have been able to carefully examine, now 

 amounts to 22 5 and 15 $ . The external lobe of the tarsus of fourth 

 leg is almost invariably provided with three spines, a single specimen 

 with four such spines being the only exception I came across. In no 

 case is the superior process of the tarsi shorter than the lateral lobes. 

 The pectinal teeth vary as already recorded. The finger-keel is not 

 rarely broken up into granules in its proximal part, so much so, 

 sometimes, that the smooth distal portion only occupies ^ of the 

 length of the keel. The posterior side of the brachium is always 

 furnished along the middle, especially in the distal half, with some 

 coarse isolated granules, in addition to the semicircular ridges
