eminent Swedish Araneologist — Erigone impolita. The radial joint 

 of the palpus is short, and has only two very small pointed pro- 

 jections from its extremity. The digital joint is large, and has 

 a strong conical prominence near the middle, giving it only a 

 little less unusual form than that of Walckena'era pumila. The 

 palpal organs are prominent, complex and furnished with several 

 spines, of which the most remarkable are a long slender one 

 forming a large bold curve from end to end of the organs, but 

 quite free from them excepting at the extromities, and another 

 shorter, stronger, curved one at their fore extremity. 



A very rare spider, of which I have only found three or four 

 examples— among moss in spring time at Bloxworth— during 

 upwards of twenty years. It has also been found in Lancashire 

 and North "Wales. 



WALCKENAERA ELAVIPES. 



Walokenaera flavipes, Blackw., Spid. Great Brit, and Irel. 

 p. 298, pi. xx., fig. 213. 



This spider is about the same size as Walckenaira pumila, the 

 male measuring 1-1 5th of an inch in length, and the female 

 l-14th ; it is also nearly allied to that species, but may be dis- 

 tinguished, not only by the greater elevation of the caput, but 

 also by the absence of the long filiform spine connected with the 

 palpal organs, and the different form of the digital joint. 



The cephalo-thorax is brownish-black, the legs and palpi 

 yellow, and the abdomen black. 



The caput is moderately olevated, the elevation not being con- 

 fined so much, as in the last species ( Walckena'era obmiraj to the 

 occiput, of which the profile of the hinder part is almost vertical; 

 and there is a strong indentation directed backwards from each 

 of the lateral pairs of eyes. The hind-central eyes are 

 placed at the upper side of the fore part of the elevation, and 

 the other three pairs nearly about half-way towards the lower 

 margin of the clypeus. The radial joint of the palpus is con- 

 siderably produced at its fore extremity, which is directed out-
