new Oenera nnd Specien of British Spiders. 105 



Palpal organs bearing usual t'alcit'orm process on outer side 

 at haso ; apex of organs on inner side exhibit two short stout 

 spines, curving slightly towards each other, while a third 

 springs from near tiie base of the u[)per of these and curves 

 round and over its apex behind. The bulb bears the usual 

 short, conical, apical prominence common to several of the 

 genus. 



Epiyyne consisting of a deep orifice, oval-triangular; ante- 

 rior margin forming an angle, posterior margin slightly 

 rounded ; otherwise closely similar to those of the allied 

 species. 



P. pygmctum is a much darker spider than any others of the 

 genus ; the eyes are nearer together and the hairs on the 

 clypous are mure numerous. The palpal organs considerably 

 resemble those of ohlonyum and errans^ but the very small eyes 

 of the former and the metatarsal spine of the latter will 

 prevent any confusion. 



This small spider does not seem to be very plentiful, but 

 perhaps has been overlooked. It occurs, however, abun- 

 dantly in and around Carlisle, running upon railings, parapets 

 of bridges, on walls, in buildings, on the pavements, &c., in 

 the mouth of April and again in October.
