696 JOHN HEWITT. 



metatarsus I scopulate below in the distal fifth or 

 sixth, the under side thickly spined on each side, 

 and also with 1-3 spines along the median line : 

 tarsus I with 1-2 spines on the posterior side but 

 none on the anterior side, III with 4-6 anterior and 

 7-9 posterior spines, IV with 2-3 on the posterior 

 side and 14-15 on the anterior side : carapace with 

 3 low keels, the lateral ones abbreviated behind, the 

 median one continued to the fovea. (Bushman's 

 Drift, near Ashton.) S. brevipalpis PurcelL 



3. Pressed forwards the palp reaches a point about f of 

 the distance along tibia I, the patella subequal to 

 patella I in length : metatarsi I and II scopulate 

 at the apex below, I without strong spines along 

 the midline inferiorly : tarsus I without spines 

 anteriorly but with 1 posteriorly, IV with 10 spines 

 anteriorly and 2 posteriorly. III with only 1 spine 

 on each side : carapace with the 3 keels obsolete, 

 only the median one being distinguishable posteriorly. 

 (Worcester.) S. erythrognathus Purcell. 



II. 1. Pressed forwards the palp reaches a point about ^ of 

 the distance along metatarsus I, the patella very 

 slightly shorter than patella I : metatarsus I not 

 scopulate infei'iorly, with strong spines below both 

 over the median area and at the sides : tarsus I with 

 3-7 spines anteriorly biit 7-8 posteriorly. IV with 

 many spines anteriorly and 8-12 posteriorly : the 

 3 keels of the carapace are flattened, especially the 

 median one. (Grahamstown.) S. schonlandi Poc. 



a. Similar to schonlandi but differing as follows : 



Metatarsus I without strong spines on the 

 median area inferiorly, or only I or 2 : 

 distance between anterolateral and antero- 

 median eyes less than the diameter of the 

 latter (much greater in schonlandi) : 

 median keel of carapace distinct froni the 

 ocular area to the fovea : distal segments 

 of palp brown (red in schonlandi.) (East 

 London.) S. spinipes sjh no%\ 



b. Similar to schonlandi but diifering thus: A 



weak but distinct scopula at apex of meta- 

 tarsi I and II and no spines along the 

 median area of this segment : tarsus I with 

 I spine anteriorly and 2 posteriorly : the
