some new African Spiders. 317 



Measurements in vnUimetres. — Total length 2Q ; cara- 

 pace 13; palpus 20; first leg 40, second 36, third 31, fourth 

 42 ; jtrotarsus 4- tarsus of first 14, of fourth 17. 



A female referred to this species gives the following 

 measurements : — Total length 33 ; carapace 15'5 ; palpus 23 ; 

 first leg 36, second 32, third 29, fourth 39 j patella + tibia of 

 first J 4, of fourth 13; tarsus + protarsus of first 10-5, of 

 fourth 14-5. 



Loc. Vredefort Road, Orange River Colony ( Capt. Barrett- 

 Hamilton). 



The male of this new species differs very markelly from 

 that of the other species known to mo in the shape of the 

 tibial apophysis of the first leg, the curvature of the pro- 

 tarsus, and the size of its distal tubercle beneatli. The 

 female is very like that of //. gigas, Poc, from the Trans- 

 vaal, but is much smaller. 



Mr. G. P. Staunton has also recently sent me specimens 

 of //. llamiltoni from Durban. 



Fam. Dipluridae. 

 Genus Bkaciiytheliscus, nov. 



Allied to Brachythele, Auss., but differing in having the 

 tibia of the first leg simple, armed with strong spines, but 

 without a spur. The tarsus of the palp is short and truncate. 



Type B. bicolor, Poc. (Proc. Zool. Soc. 1897, p. 735) 

 {Brachythele) . 



The type of this genus was based upon a single mutilated 

 female example collected by Mr. H. A. Spencer at Durban. 

 Being acquainted only with the female, I was not able to 

 separate tiie species from those of the genus Brachytliele. The 

 discovery of the male by Mr. G. P. Staunton has, however, 

 shown that the species differs from the typical species of 

 Brachythele in the absence of a tibial spur on the first leg in 

 the male. 



In both males and females the abdomen is spotted or 

 banded above. 



The male has long and slender legs ; the protarsus of the 

 first is armed beneath with 1, 1 spines, of the second with 

 2, 1, 2 spines. The palpi are short, the tibia a little exceeds the 

 patella, is inflated proximally below, and armed with two long 

 external spines beneath and one internal. The bulb of the 

 palpal organ is piriform, passing gradually into the spine, 

 which is lightly curved. 



Measurements in millimetres. — Total length 10 ; length of 

 carapace 4-5, of first leg 15, second leg 14, third leg 13, 

 fourth leg 18.
