286 Mr. 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 millim. ; 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 Stas?- 
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. Schénlandi in the compact 
arrangement of its eyes. 
Genus ACANTHODON, Guér. 
Acanthodon flaveolum, sp. n. 
? .—A small pale flavous species approaching A. Thorellit, 
O. 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. Thorellit 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. In A. flaveolum, 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 /7. 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, Kalahari Desert (R. J. Cunningham).
