On Some South African Aviculariidae (Arachnida). 87 



Measurements. Length 17'8 mm. (spinners excluded). Carapace 

 7 mm. long and 6'5 wide; 1st leg 24, 3rd leg 18'5, 4th leg 25'5 mm. 

 long. 



Very similar to S. <ji<jas (Hewitt), especially in appearance; though 

 considerably smaller. Latter however has stouter process to bulb, 

 and tarsus of first leg is far less heavily spined ; 4th tarsal claws 

 of S. gigas have 3 stout basal spines and 4 small ones distally inside 

 the curve; kentanicus has a basal comb of about 5 spines and about 

 5 sharp teeth in curve ; anterior claws also have more numerous, 

 sharper teeth. 



STASIMOPUS NANUS, n. sp. 



Specimens. A. ? (No. B 89, Type) from Smithneld, Orange Free 

 State, collected by Dr. Kannemeyer. 



Colour. Carapace and legs dark olivaceous brown ; lighter around 

 and below ocular tubercle; anterior legs slightly lighter; abdomen 

 dark above and below ; under surface of legs, coxae and sternum 

 dull medium brown. 



Carapace. Subequal in length to patella, tibia, and metatarsus I. 



Ocular tubercle. Subequal to tibia or metatarsus I. 



Anterior row of eyes with their centres in a straight line ; laterals 

 large and broadly oval, transverse to slightly oblique, and much less 

 than a median's diameter from the latter ; anterior medians small 

 and their own diameter apart. Posterior row also practically in a 

 straight line, with a tendency to slight recurvation ; medians 

 subrotund, larger than anterior medians, and not quite so wide 

 apart as anterior laterals ; narrowly separated from posterior laterals, 

 which are oval, subequal to medians in size and more raised ; 

 considerably less than their own diameter from anterior laterals ; a line 

 parallel to long axis of body and touching the outer edge of the latter, 

 would cut the posterior laterals through their centre. 



Labium with 5 teeth, coxae of pedipalps with 8-10. 



Spines. Palps with about 8 distinct spinules at base of tarsus 

 above, and one or two scattered ones on distal upper surface of 

 tibia ; 2 spines on inner surface of tibia and 5 on outer ; and a band 

 of spines down each side of tarsus. Metatarsus I with basal patch of 

 spiuules extending over about -\ of upper surface ; area of spinules at 

 apex of tibia above, very small. Metatarsus II with the basal patch 

 of spiuules extending over about ^ of its surface ; that on the tibia 

 being less in size but greater than on tibia I. Inner surface of 

 tibia I with 3-5 spines; outer surface with about 25 spines. 

 Metatarsus III with about 10 spines on its anterior surface, and
