734 MK. R. 7. POCOCK OX ETHIOPIAN SPIDERS. [Juue 15, 



1st leg ; clypeus nearly as long as the ocular area ; anterior line 

 of eyes slightly procurved, wider than the posterior line ; posterior 

 lateral eyes smaller than posterior median ; radiating grooves on 

 the carapace represented by shallow depressions, with the excep- 

 tion of a deep pit on each side behind the head. 



Mandible armed below with 4 large internal teeth and 4 external, 

 of which 3 are much smaller than the other. 



Distal half of labium and front half of lower side of maxilla 

 armed with strong spicules. Sternum broad, its width between the 

 1st coxffi equal to about half its length ; furnished with a single 

 pair of large sigilla remote from the margin and opposite the coxae 

 of the 3rd leg; coxce of 2nd and 3rd legs armed behind with a 

 cluster of spinules, that on the 3rd greater than that on the 4th. 



Legs — 1st and 2nd pairs stouter than 3rd and 4th ; 4th a little 

 longer than the 1st; tibia of 1st armed internally with 4 spines 

 externally with 8, of which 3 are small and short ; tibia of 2nd 

 with 3 in front and 5 behind ; protarsus of 1st with 8 larger and 

 smaller behind and 6 in front ; protarsus of 2nd with 7 behind 

 and 6 in front ; tarsi unspined ; 3rd and 4th legs almost without 

 spines, one stout one on the anterior side of the patella of the 3rd 

 and spiniform setse on the lower side of the 4th protarsus. Claivs 

 armed with a single long tooth and one or two smaller ones behind it. 



Paljj short, slender, extending just past the patella of the 1st leg, 

 its tibia armed with 1 outer and 1 inner spine, tarsus with 2 outer 

 and 2 inner spines. 



Measurements in millimetres. Total length 15 ; length of cara- 

 pace 7, width 6 ; length of palp 6-5, of 1st leg 11-5, of 2nd lO'S, 

 of 3rd 9, of 4th 13. 



Loc. The Nj'ika plateau 6000-7000 ft., between Lake Nyasa and 

 Lake Tanganyika {A. Whyte). 



The three species of the genus known to me may be readily 

 recognized by the following table : — 



a. Sternum broader in front, its widtli between the 1st 

 legs equal to about half its length ; cluster of spinules 

 on base of 3rd coxa larger than that on the 1st ; eyes 

 of anterior line nearly straight, the laterals separated 

 from the edge of the clypeus by a space which is 

 about equal to three diameters ; posterior median eye 



larger than the posterior lateral whyiei, sp. n. 



h. Sternum narrower in front, its width between the 1st 

 legs less than half its length ; cluster of spinules on 

 base of 3rd coxa larger than that on the 4th ; distance 

 between anterior lateral eye and edge of clypeus less 

 than three times a diameter, the anterior row of eyes 

 being more strongly procurved ; posterior lateral eye 

 larger than posterior median, 

 a'. Eyes smaller and more scattered, the anterior laterals 



twice their diameter from the edge of the clypeus 



and three times their diameter from the medians, 



which are separated by a space equalling twice their 



own diameter ; six spines on the outer side of the 



tibia and protarsus of 2ud leg ; legs more or less
