Species of African Solifugse and Arane^. 21 



Family Heteropodidae. 



Selenops Marshalli, sp. n. (PI. II. fig. 6.) 



cJ. — Colour. Integument ochre-brown, covered with a 

 mixture of golden-yellow and blackish hairs ; legs mixed 

 with blackish. 



Eyes as in 8. atomarius and Spenceri ; those of the 

 median quadrangle strongly recurved, the posterior medians 

 twice the diameter of the anterior medians, with their lower 

 edges only a little lower than the upper edges of the anterior 

 medians, the latter equidistant from each other and from the 

 edge of the clypeus, /. e. a little more than their own radius ; 

 anterior lateral standing high above the edge of the clypeus, 

 about on a level with the lower border of the posterior medians. 



Tibife of first and second legs with seven pairs of inferior 

 spines, protarsi with three pairs. 



Palp with its tibia armed with four apophyses — one infe- 

 rior, large, and irregularly quadrate ; one projecting externally 

 almost at right angles and somewhat conical in shape ; and 

 two much thinner and somewhat spiuiforra, which run forwards 

 to abut against the outer side of the base of the tarsus — of these 

 the outer is blade-like, straighter and shorter, being a little 

 more than half the length of the inner, which is sinuous and 

 upcurled apically ; to abut against its upcurled apical portion 

 the tarsus is furnished externally and basally with a distinct 

 angular prominence. 



Measurements i7i millimetres. — Total length 11; length of 

 carapace b'D, of first leg 2^, of second 28*5, of third 30. 



Loc. Estcourt (4000 feet), in Natal {G. A. K. Mamhall). 



Selenops Whitece, sp. n. (PI. II. fig. 7.) 



(J. — Nearly allied to the foregoing, but distinguishable 

 by the structure of the palpal spurs &c. The lower til)ial 

 apo])hysis has a much wider and deeper notch on its outer 

 side near the base, and its distal edge, instead of being 

 straight and transverse as in S. Marshalli, is more oblique, 

 the whole apophysis being longer than in that species ; the 

 external apophysis, moreover, has its apex not curved down- 

 wards and forwards, but directed straight externally ; of the 

 two forwardly-directed apophyses the outer is thinner, more 

 cylindrical, and less blade-like than in S. Marshalli, while 

 the inner has its upper margin convex in its basal half and 

 concave in the distal, not evenly concave throughout as 

 in S. Marshalli ; and, lastly, in S. Whitem there is uo
