Female. 
The more important characters of the female are as follows : — 
Legs . — Coxa III with a post-ventral tuft of stifhsh setae, which in 
the basal third or half of the segment take the form of sharp spinules. 
Coxa II without a trace of spinules. Metatarsus III with 2 long spines 
at the apex inferiorly, but none or only 1 or two weak ones on the lower 
surface. Band of spines on anterior surface of tibia II including 3, 4, or 
5 spines or even only 1. Patella III with 5-8 spines along the anterior 
surface, including those on the distal edge ; IV with a band of 9-14 stout 
but short spines, extending about half-way along the segment or less (in 
an immature specimen only 6 spines). 
Chelicerae with an inner row of 5 fairly strong teeth and an outer row 
of 3 or 4 small ones. 
Ocular area about as long as J of the distance from the anterior margin 
of the carapace to the fovea. Posterior median eyes about 1J-2 diameters 
apart and about a diameter distant from the posterior laterals. Posterior 
margins of posterior row in a straight line. Posterior laterals elongated. 
Frontals about J-f of a diameter apart. There are three very long bristles 
on the cephalic area, one between the anterior medians and a pair situated 
midway between the point of origin of this single bristle and the fovea. 
Labium with 2 apical teeth. 
Sternal sigilla . — Three pairs, the first pair submarginak 
Colour . — Carapace and legs olive-brown, the palps and first two pairs 
of legs darker than the hind two pairs of legs. 
Measurements . — Total length 11 *5 mm., length of carapace 4, breadth 
of carapace 3 -25. 
This is an unusually small species. Mr. Gr. van Dam has recently 
taken male and female examples at Wolhuters Kop in the Rustenburg 
District. 
Acanthodon paucispinulosus Hewitt. 
This was described by me (Annals Trans. Mus., V, p. 98) as a variety 
of transvaalensis, to which it is undoubtedly closely related. The spinules 
on coxa III are somewhat stouter but less numerous than in transvaalensis. 
The first sternal sigilla are clearly separated from the margin of the sternum, 
but only very slightly so on one side in one of the types. Patella III with 
about 25-30 or even several more spines along the anterior surface, 
including those on the distal edge : IV with a group of about 40-50 short 
stout spines extending over |— ^ of the length of the segment anteriorly. 
Band of spines on anterior surface of tibia II, including about 4-7 spines. 
The pair of stouter spines posterior to the ocular area is much nearer to 
the anteromedian eyes than to the fovea. 
Acanthodon cp. grandis Hewitt (Annals Natal Mus., Ill, pt. 2). 
From Forbes Beef, Swaziland, and Lochiel, Ermelo District, Mr. A. 
Roberts took female examples which seem to be closely related to grandis 
and also to abrahami. There are three pairs of sternal sigilla, the first pair 
submargina : there is a strip of stiff bristly hairs along the posterior border 
of coxa III inferiorly. The ocular arrangement is slightly different from
