NEW AND RAR BRITISH SPIDERS. 39 



margin of the curve near the posterior end of the produced portion 

 is a prominence ending in a curved pointed spine directed out- 

 wards. The digital joint is large, of an oval form, and is somewhat 

 angularly prominent towards its fore-extremity on the outer side. 



The palpal organs are somewhat complex, greatly developed, 

 with a curved corneous blunt-pointed hook-like process at their 

 base on the outer side ; a corneous lobe, long and of irregular 

 form, projects considerably beneath and outwards, and a long 

 strong tapering circularly curved black spine issues from beneath 

 their extremity, and has its fine point in near connection with 

 the end of the corneous lobe mentioned above. 



An adult male of this very distinct species was kindly com- 

 municated to me by Mr. W. Evans, of Edinburgh, by whom it 

 was found at Glenfarg, in Perthshire, in 1899. It is allied to 

 Tapinocyba, Sim., and more nearly to Prosopotheca, Sim., but is, I 

 think, distinct from both.
