(a) 28 2 (15 ad.) and 19 ^ (2 ad.) from Zwartmodder : Number 

 of peetinal teeth in ? 15-18, in ^ 19-23 ; length of cephalothorax 

 in ? 16^^-19 mm., in 3' 16J-17|- mm. These specimens are of a 

 much larger size than the types from Naroep, as they measure up to 

 135 mm. ( $ ) and 180 mm. ( <^ ) in length. In the ad. 3^ the tail is 

 4f times as long as the cephalothorax, which is equal to, or slightly 

 less than the femur of the pedipalp in length ; moreover, the upper 

 surface of the hand is less smooth than in the types, being more qr 

 less granular near the denticulate inner margin. In the ad. ? the 

 tail is more than 3f and often nearly four times aS' long as the 

 cephalothorax. 



(b) 2 ad. ? , 8 ad. <y and a number of juv. from Beeststert near 

 Coboop in the north-west corner of Kenhart Div : Large specimens, 

 nearly equalling gigas in size and measuring up to 147 mm. (?) and 

 132 mm. ((3") in length.

 length of cephalothorax in ad. ? 11^-13 mm., in ad. 3 11-12^ mm. 

 In the ad. ? the fifth abdominal sternite is very weakly granular 

 posteriorly or almost entirely smooth, the length of the hand-back 

 generally very distinctly exceeds the width of the hand, and the first 

 caudal segment is generally almost smooth below in the anterior part 

 and sometimes only very weakly granular in the middle posteriorly. 

 In the ad. 3 the first abdominal sternite and often also the second 

 (except laterally) are frequently smooth.
