This species, as Westring remarks, is extremely like E. ru/a 

 or erythrocephala Westr. I am acquainted only with the male, on 

 whose palpi the patellar joint is very short, almost double as short 

 as the tibial joint; it has at its apex a straigld, pointed, coarse 

 bristle or rather spine, coarser than any bristle on the legs. Viewed 

 from in front the tibial joint is almost cylindrical , longer than it is 

 broad, hairy; it is convex beneath. The clava is large, thicker 

 than the thighs of the l:st pair of legs, rather longer than the two 

 preceding joints put together; the lamina has a strong, angular 

 protuberance at the base, as in E. ru/a; the bulbus is very com- 

 plicated and has at the base a large, coarse appendage, curving 

 rapidly forward, as in that species, which appendage however has 

 no backward-directed tooth, nor is there any circular membranous 

 band on the outside of the bulbus; on its under side, nearer the 

 base, may be seen a strong spine or claw curved upwards and di- 

 rected outwards. 



It is in consequence of a communication from Cambridge, to 

 whom I had sent specimens of this spider, that I have been enabled 

 to take up Ner. silvatica Blackw. as a synonym of it. — Menge has 

 kindly favoured me with specimens of his Bathyph. setipalpus: the 

 male is the same as E. silvatica or silvestris 3, but the female spe- 

 cimens I cannot distinguish from E. erythrocephala Westr., with 

 which however Menge's description does not appear to me very well 

 to agree, and I therefore suspect that these specimens do not belong 

 to the form which Menge has described as ? of his B. setipalpus.

This species is very closely connected with the two preceding, 

 especially E. silvatica (silvestris); even the male's palpi are very much 

 alike in these two species. The patellar and tibial joints of E. 

 cequalis Westr. are almost such as we have described those of E. 

 silvatica; the patellar joint however has no spine at its apex, but 

 only a fine bristle, as in the tibial joint, which is about half as long 

 again as the short patellar joint. The clava is rather thicker than 

 the thighs of the first pair, irregularly rounded , at least half as long
