ing a large, concave, cup-like cavity. Its apex is depressed and 

 its outer margin is clothed with long black hairs. 



The palpal organs exhibit the normal falciform jwocess on 

 the outside at the base, while at the apex are two spur-like 

 apophyses, one stout, black, and sinuous, the other paler and 

 more slender, their points curving across each other. A long 

 circular spine, stout at the base, lies within the concavity of the 

 apex of the digital joint, not easy to see nor of much specific 

 importance (fig. IV. 1, 2). 



The epigyne of the female is not prominent nor produced into 

 a tongue-like or ovipositor-like process. Viewed in profile it 

 forms a short, stout, sparsely truncate, conical prominence 

 (fig. IV. 3, 4). 



The italicized portion of the above description contains 

 specific characters only. 



This species can be distinguished in both sexes from ex- 

 pertus, Cambr., arcanus, Cambr., bicolor, Bl., concinnus, Th., 

 sylvaticus, Bl., and pjrudens, Cambr., by the absence of femoral 

 spines. 



In the male sex, from rufus, Wid., and affinis, BL, by the 

 absence of a tooth in front of the basal joint of the falces upon 

 the inner side. 



From scopiger, Grube, and Warburtonii, Cambr., by the ab- 

 sence of the series of stiff spines upon a prominence on the 

 inner side of the radial joint. From Huthwaitii by the very 

 much larger digital joint and quite short inconspicuous radial 

 joint of this latter species. 



From abnormis, Bl., by its much smaller size and by the 

 large concave radial joint above described ; niger, F. Cambr., 

 is also black in colour, while abnormis, BL, is orange-yellow. 



In the female sex, niger, F. Cambr., may be distinguished 

 from scopiger, Grube, Warburtonii, Cambr., rufus, Wid., and 

 abnormis, BL, by the much more prominent epigyne in these 

 species. Huthwaitii, Cambr., and ajfinis, BL, are much larger 

 spiders. 



This fine spider does not seem to have been described before. 

 Ten specimens were taken by myself on Sept. 18, 1890, 

 beneath loose pieces of stone scattered in abundance upon the 

 summit of Helvellyn. The females were usually found 

 beneath a thin horizontal sheet of webbing stretched across 

 depressions in the soil beneath the stones. 



Genus MiCEONETA, Menge, Simon. 

 This genus contains several small, slender, elegant, fine- 

 legged, active spiders hitherto placed by English arachnolo- 

 gists in the genus Neriene. They exhibit, in common with
