84 Rev. F, O. Pickard-Cambridge on 



tooth on either side (above and below) the point of articulation 

 of the fang. 



The basal joint is also grooved on its external lateral sur- 

 face with deep transverse striations, its frontal surface bearing 

 towards the outer margin a few minute setigerous tubercles 

 (fig. VII. 1,2). 



Legs short and slender. Femoral dorsal spines absent (one 

 beneath near apex) ; one genual and two tibial spines ; no 

 metatarsal spines. Metatarsi of first two pairs of legs shorter 

 than the tibiae. 



Palpus of Male. — Humeral joint curved and slightly incras- 

 sated towards the apex (exhibiting on the inner side close to 

 the base a small spine-bearing tubercle, apparently connected 

 with and perhaps working upon the transverse striations on 

 the falces). 



Cubital joint as broad as long, convex above, bearing near 

 its apex, besides a few short hairs, a single stout sinuous bristle. 



Radial joint about as broad as long, wider in front, and 

 somewhat angular and prominent on the upper anterior mar- 

 gin, bearing only a few short hairs. 



Digital joint (viewed in profile) very slightly prominent near 

 the base above. Palpal organs bearing at the base below on 

 the inner side a short, stout, obtusely conical, squarely truncate 

 prominence, curving inwards (viewed from above). This 

 prominence (viewed in profile) is directed backwards as a stout 

 blunt spur (fig. VII. 3, 4). 



Epigyne of female appears as a conical obtusely truncate 

 prominence, very broad (broader almost than long), slightly 

 bilobed at the apex, which is furnished with a small, bifid, 

 chitinous tongue, having on either side two concavities. 



The form of the epigyne is almost exactly similar to that 

 of rurestris, C. K., and I cannot give any character other than 

 the deeper coloration of the cephalothorax and abdomen and 

 the darker red-tinged legs to help to distinguish the two 

 (fig. VII. 5). 



The species was first described by the Eev. O. Pickard- 

 Cambridge, in a list of northern spiders published in 1875 *, 

 from a specimen found upon the Cheviot Hills. No speci- 

 mens have been captured since that time until Sept. 1890, 

 when I myself had the good fortune to discover seven or eight 

 of both sexes beneath stones upon the steep sides of one of the 

 " passes " usually traversed in ascending Mount Helvellyn, in 

 Cumberland. Many more specimens could doubtless have 

 been obtained.
