318 Mr. R. I. Pocock on Arachnida from 



Palpal organ with the spine stoutish, blunt at the apex, 

 with a conspicuous crest or keel just above it. 



$ . — Colour the same as in the male ; cljpeus about half 

 as long as the tubercle ; carapace at least as long as patella 

 and tibia of first and fourth legs, a little shorter tlian tarsus and 

 protarsus of fourth, the width equal to the patella and tibia of 

 the second, equal to the fourth protarsus and half the tarsus ; 

 length from fovea to anterior margin a little less than fourth 

 protarsus and than patella and tibia of third leg. 



Measurements in millimetres. — ^. Total length 19 ; length 

 of carapace 10, width 8 ; length of first leg 28*5, of second 

 26, of tliird 25, of fourth 32 ; patella and tibia of first 10"2, 

 of fourth 10; protarsus of fourth 8"8. 



? . Total length 26; length of carapace 11 "5, width 9" 5; 

 length of first leg 28*5, of second ^Q'6, of fourth 32 ; patella 

 and tibia of first 11, of fourth 11, of fourth protarsus 8"5. 



Loc. Barberton, Transvaal [Percy Rendall). 



This species may be recognized as follows from the only 

 other male of the genus known : — 



a. Of small size (carap. 10 mm.) ; protarsus of first 



leg straight ; carapace not longer than patella, 



tibia, and tarsus of palp ; spine of palpal organ 



■with a strong upstanding crest and a blunt point. nigrofulvuSy sp. u. 

 h. Of large size (carap. 16 mm.) ; protarsus of first 



leg basally sinuate ; carapace much longer than 



patella, tibia, and tarsus of palp ; spine of palpal 



organ simple and attenuate vorax, Poc. 



Tiie females of the three species in which this sex is known 

 may be distinguished as follows : — 



a. Ocular tubercle rounder, not very much wider than 



long, and separated from the edge of the carapace 



by a space equalling quite half its length. 



a^. Carapace longer than patella and tibia and than 



tarsus and protarsus of fourth, almost as long 



as tibia, protarsus, and tarsus of third leg; 



length from fovea to anterior border greater 



than fourth protarsus vorax, Poc. 



b^. Carapace as long as patella and tibia of fourth, 

 shorter than tarsus and protarsus of fourth and 

 than tibia, protarsus, and tarsus of third leg; 

 length from fovea to anterior border less than 



fourth protarsus nigrofulms, sp. d. 



6. Ocular tubercle more transversely elongate, the 

 clypeus less than half its length (carapace and 

 leg-measurements as under b'^) murinus, Poc.
