neio South- African Spiders. 325 



Closely resembling X. communis, sp. n., in cliavacters of 

 carapace, eyes, spine-armature, and scopulie of legs, &c. 



Lengtli of clypeus subequal to the length of an anterior 

 lateral eye. 



Legs rather longish, the first tibia in the J with a few 

 inner scopular hairs. 



Chelicera with a strong inferior tooth. 



Pedipalps of c? longer than in X. communis, the patella 

 as long as the tibia (exclusive of the process), but the two 

 segments together longer than the tarsus ; lateral process of 

 tibia short and stout, the apex suddenly narrowed and claw- 

 like, strongly curved inwards and a little downwards 

 (PI. XIV. fig. 38) ; palpal organ larger and more extensively 

 chitinized than in communis, the apical spine very short 

 (PLXIV. fig. 38 a). 



Vulva of ? nearly but not quite like that of comtnunis, 

 differing mainly in the form of the receptaculum semiuis 

 (PI. XIV. fig. 39). 



Length of trunk, (^ lOi, ? 12 mm. 



14. Xerophceus crustosus, sp. n. (PL XV. fig. 40.) 



1 (^ from East London (/. Wood). 



Allied to X. communis, sp. n., but larger. 



Cat-ajyace mahogany-red, the head narrow ; anterior median 

 eyes with their lower margins situated slightly below the 

 level of the centres of the lateral eyes, the clypeus a little 

 longer than a lateral eye ; posterior row of eyes much wider 

 than the anterior row, the median eyes equal to the laterals 

 in size and at least f of a long diameter apart, distant from 

 the laterals about 1.] times a long diameter. 



Chelicera with weak lower tooth, but strong upper teeth. 



Legs very robust, the first tibia with 0-1 outer and 2 inner 

 spines below. 



Fedipalps. — Tibia (viewed from above) attenuated at base, 

 its length (exclusive of the process) slightly less than that of 

 the patella, the lateral process resembling that of X. coin- 

 munis in shape, but very long, much longer than the rest of 

 the joint, and reaching as far as the distal end of the palpal 

 organ, its distal part slightly curving upwards, the apex 

 pointed and minutely incurved ; palpal organ very like that 

 of A'', communis, the apical spine short (PL XV. fig. 40). 



Lensth of trunk 11 mm.
