PI. XI, Fig. 26. 
Specimens. a) I $ from between Khakhea and Kang, Kalahari, Bechuanaland Protectorate. 
Colour of cephalothorax brown, the margins black, the surface sparsely clothed with prone white 
hairs, finely reticulated with black towards the sides, especially on the head, a longitudinal median band on 
the head and a broader stellate area on the thorax without black reticulation; chelicera brown, with infuscate 
stripes; femora, patellae and tibiae of legs (except tibia III) broadly blackened but otherwise yellowish, 
fourth metatarsus also infuscated, the other metatarsi, the tarsi and tibia III, as well as the coxae and 
trochanters, pale-yellowish ; abdomen white on the anterior % of the upper surface and on the anterior % at 
least of the lower surface, black posteriorly, the upper surface also with a median black band which divides 
the white part and expands laterally on the vertical anterior surface, the arms being continued backwards 
on each side over % of the length of the abdomen and terminating in a triangulär dilation, the whole 
forming an anchor-shaped design; the white area on each side of the median dorsal band of abdomen 
forming a large longitudinal oval patch, which is connected posteriorly with the white ventral area; hind 
end of abdomen with a pair of small angular white spots above near the median line. 
Cephalothorax broad in front. Anterior row of eyes procurved, the lateral eyes large, much 
larger than the medians and close to them, and almost their own length from the anterior margin ; posterior 
row of eyes slightly procurved (a trifle wider than the anterior row on one side of the head), the lateral 
eyes larger than the medians but smaller than the anterior laterals, the medians small, elongate, much nearer 
to the laterals than to each other. 
Chelicera robust, the inner margin with 3 strong superior teeth, of which the middle one is a 
little larger than the other two ; no inferior teeth. 
Legs. First pair of legs without spines, the tarsus and metatarsus scopulate; second pair with 
I inner and 2 strong outer spines on the metatarsus below. 
Vulva as in PI. XI, Fig. 26, the fovea longitudinal and very close to the 2 posterior spherical 
brown bodies. 
Length of cephalothorax -f- abdomen 5 b / 4 mm. 
b) 1 $ from Bonche in the Kalahari, Bechuanaland Protectorate, January 1905. Legs and cephalo-
