440 Mr. R. I. Pocock on Arachnida from the 



although long, are thick, and could only be described and 

 figured as bristle-like as the result of very defective vision *. 



Family Zodariidae. 

 Genus Stokena, Walck. 



Storena nyikce, sp. n. (PI. XIII. fig. 4.) 



Colour. Carapace, sternum, and mandibles deep reddish 

 black ; legs ferruginous ; palpi ferruginous, with the tarsus 

 infuscate ; abdomen greyish black above, paler below, with a 

 median dorsal series of indistinct yellowish spots, paired on 

 the anterior half of the abdomen, united in the middle line in 

 the posterior half. 



Carapace high, its length equal to that of patella and tibia 

 of fourth leg ; clypeus vertical, high, its height from the 

 anterior lateral eye equal to the length of the mandible and a 

 little greater than the length of the ocular area. Eyes of 

 anterior line strongly procurved, the inferior edges of the 

 medians slightly higher than the superior edges of the laterals ; 

 anterior medians the largest of the eyes, about half a diameter 

 apart, about their own diameter from the anterior laterals and 

 a little more than that from the posterior medians ; ocular 

 quadrangle oblong, longer than wide, the posterior medians 

 about a diameter apart, anterior medians and posterior laterals 

 forming a slightly recurved line, anterior and posterior laterals 

 about a radius apart. 



Legs slender, 4, 1, 2, and 3 ; spiny. Palpi with patella 

 and tibia short, the latter with a stout down-bent external 

 tooth ; tarsus long and high, twice as long as patella and 

 tibia taken together. 



Abdomen broadest in its posterior half. 



Measurements in millimetres. — Total length 7 ; length of 

 carapace 4, of first leg 10, of second and third 9'5, of 

 fourth 11. 



Loc. Nyika plateau, 6000-7000 feet {A. Whyte). 



Seems to differ from S. senegalensis, Simon (Ann. Soc. Ent. 

 France, 1885, p. 373), based upon an immature female from 

 Senegal, at least in the pattern of the abdomen and in having 

 the eyes of the anterior line unequally spaced. 



* Simon's statement (Hist. Nat. AraignSes, 1898, p. 376) that foUifera 

 is without doubt identical with P. Lucasii, Vinson, from Madagascar, 

 has no justification in fact.
