NEW SOUTH AFRICAN ARACHNIDA. 307 



Frontal eyes quite separate from each other, about half a 

 diameter or a trifle more apart. The quadrangle formed by 

 the frontal and anterior median eyes is appreciably wider 

 behind. Hind marg-ins of posterior row of eyes in a pro- 

 ciirved line. Posterior median eyes three to three and a half 

 diameters apart. 



Tarsus of palp witli one rather long- stout spine at the apex 

 dorsally, and several much weaker ones. Pocock's figure of 

 the tibia of the palp is quite inaccurate in respect to the 

 :spinulation of the excavation ; the spinules are not arranged 

 in a single row throughout, and are much more numerous 

 than represented in the figure ; distally they occupy two or 

 three rows, and proximally the spinules are considerably 

 longer than elsewhere. 



All the tarsi are scopulate to the base, the fourth being 

 without spinif orm seta; mesially below. Tarsal claws without 

 a comb of teeth, the first having only one large tooth and the 

 fourth one or two. The first tibia has four spines along its 

 outer inferior edge, but none otherwise situated, apart from 

 the two large tubercles. 



The inner dental series of the cheliceras comprises five large 

 teeth. 



The first pair of sternal sigilla is near to the sternal 

 margin.

 Acanthodon hamiltoni Poc, Ann. Mag. Nat. Hist., 7, x, p. 320, 1902. 



The type of this species is without doubt very juvenile. 



The inner dental series comprises five strong teeth and a 

 few small ones basally situated. The coxfe of the legs are 

 without spinules, and alojig the posterior edge of the third 

 ■coxa inferiorly is a strip of moderately fine hairs. The second 

 tibia has a row of eight spines on its anterior side. The band 

 of short strong spines on the anterior surface of the fourth 

 patella extends two-thirds of the distance along the segment. 

 Tlie frontal eyes are very close together; the ocular tubercle 

 is deeply grooved above.
