over the base of the digital joint, and has a spine-like process 

 beneath its extremity, thus appearing bifid at that part. The 

 radial joint is produced also, but less strongly, on the outer side, 

 its curve being opposed to that of the other apophysis; the 

 extremity of the radial joint appears thus to have had a large, 

 somewhat circular piece taken out of it. 



The palpal organs are moderately complex and very pro- 

 minent. A strong, filiform, red-brown, prominent spine is con- 

 nected with them, and is very conspicuous near their extremity 

 on the outer side. 



I have frequently found this little spider on furze bushes and 

 underwood, as well as among low plants and herbage in woods at 

 Bloxworth and in the neighbourhood. 



WALCKENAEEA ERYTHEOPUS. 



Erioone ERYTHRorus, Westr., Aran. Suec. p. 237. 

 Walckenaera borealis, Cambr., Zoologist, 1862, p. 7967. 



Tho adult male measures l-12th of an inch in length. 



The elevation on the caput is moderate, about the same as that 

 of Walc!cenaerapusilla,~Widi., but more massive; and the spider itself 

 is much larger and differs considerably in colours. The indenta- 

 tions on the sides of the elevation, behind the lateral eyes, are 

 also larger, but do not compress the sides so much. The slope 

 of the ocular area, looked at in profile, together with the profile of 

 the clypeus, is nearly the same as that of Walckenaera pusilla. 

 The eyes of the fore central pair, looked at from in front, are 

 above the straight line of the lateral pairs. 



The cephalo-thorax is of a glossy, brownish-black colour ; the 

 legs and palpi yellowish-red, the latter of rather a paler tinge ; 

 and the abdomen glossy, deep brownish-black. 



The radial joint of the palpus is stronger than the cubital, and 

 has its upper fore extremity, rather on the outer side, produced 

 into a strong apophysis which curves over the base of the digital 

 joint, its bluntish point directed outwards ; from within the cur- 

 vature there issues a rather conspicuous prominent process, also
