286 3Ii-. R. I. Pocock on some 



Legs spiny, long and slender, with tarsi scopulate and 

 laterally spined ; no tibial spur on first leg. 



Total length 16 niillim. ; carapace 6 ; palp 11 ; first leg 20, 

 second leg 17, third leg 15, fourth leg 23. 



Loc. King William's Town. 



This is the first publication of the male characters of Slasi- 

 mopus. Unfortunately none of the described females have 

 been recorded from King William's Town. Hence it is not 

 possible to refer this male to either of the three known 

 species. It differs markedly from S. Schonlandi in the compact 

 arrangement of its eyes. 



Genus Acanthodon, Guer. 

 Acanthodon Jlaveolum, sp. n. 



? . — A small pale flavous species approaching A, Thorelliij 

 0. P. Cambr., in size and colour, but hardly likely to be the 

 female of that species on account of the greater length of the 

 quadrangle formed by the anterior median and anterior lateral 

 eyes. In A. Thoreltii this quadrangle is about twice as long 

 as wide, and the distance between the two posterior lateral 

 eyes is greater than that between either of these eyes and the 

 edge of the clypeus. \\i A. Jlaveolum ^ on the contrary, this 

 ocular quadrangle is almost or quite three times as long as 

 wide, and the main ocular cluster lies so far back that the 

 distance between the clypeus and a posterior lateral eye is 

 greater than the width of the cluster. 



Total length 19 millim. ; carapace 8. 



Loc. Near Grahamstown (^Mrs. White). 



Genus Heligmomerus, Simon. 

 Heligmomerus deserti^ sp. n. 



Eyes less compact than in LI. somalicus ; the clear amber- 

 coloured area of the anterior medians more than two diameters 

 apart and at least three diameters from the posterior laterals ; 

 posterior medians larger than anterior medians and at least 

 as large in area as the posterior laterals ; the quadrangle 

 formed by the anterior medians and anterior laterals only 

 about one third longer than wide ; the tubercles of the anterior 

 median eyes separated by a space which about equals their 

 own diameter. 



Total length 18 millim. ; carapace 10. 



Loc. Kalahaii Desert (^R. J. Cunningham).
