South, African Arachnida. 141 



with neglectus and gramdatus, e.g., in the Divs. of Worcester, 

 Eobertson, and Uitenhage. To the north-east of this coast strip is 

 an area of unknown extent but comprising the Divs. of Graaff 

 Eeinet and Albert, which is inhabited by a variety of capensis which 

 I have called /re? jc/n". 



To the north of the rainy coast strip is a vast dry and elevated 

 area of karroo-like country with very little rain, inhabited principally 

 by the two species neglectus and gramdatus, which are found right up 

 to Bushmanland and German South-West Africa, while to the east 

 gramdatus has been found to occur as far as the Divs. of Victoria 

 West and Uitenhage. The actual northern and eastern limits of 

 these species are, however, not yet known. 



P. calvus has been found in only two localities in the Divs. of 

 Calvinia and Clanwilliam, i.e., within the distribution area of 

 neglectus and gramdatus. It is, however, exceedingly rare. 



In the north-western part of Cape Colony is an extremely arid 

 tract of country known as Great and Little Bushmanland (forming 

 part of the Divs. of Kenhart and Namaqualand) , the fauna of which 

 appears to resemble that of German South-West Africa rather than 

 that of the rest of Cape Colony. In this region no fewer than 

 six species, viz., hrevimanus, IcBvifrons, villosus, schlechteri, neglectus, 

 and gramdatus, have recently been collected by Mr. Max Schlechter, 

 who found them living side by side. Of these the first four are not 

 known to occur in other parts of the Colony to the south of the 

 Orange Eiver, while at least four, but probably all of them, are found 

 in German South-West Africa. From the latter region another form, 

 P. rauclus (Sim.), has been recorded by Simon. 



The only other species which have been described from Cape 

 Colony are P. flavidus Poc, P. ohscurus and iMcliysoha Penth., all 

 from Bechuanaland, but unfortunately the Museum possesses no 

 material from this part of the country. 



Only one species, P. transvaalicus Pure, has been recorded 

 from the Transvaal, and one, P. mosamhicensis (Pet.), from 

 Rhodesia. 



The South African species known to me may be determined from 

 the following table : — 



a. Posterior upper edge of 2nd caudal segment strongly elevated and curved 

 forwards in the middle. Legs yellow. Western Divs. of Cape Colony 

 (from Tulbagh and Worcester Divs. northwards), German South - West 

 Africa 5. P. neglectus Pure. 



h. Posterior upper edge of 2nd caudal segment perfectly straight. 



a'. Sides and under surface of 4th caudal segment densely and finely
