trees, as well as among moss in woods in spring and early 

 summer months. It has also occurred in other parts of England, 

 in Wales, and Scotland. 



WALCKENAERA PERMIXTA. 



Walckenaeka pehmixta, Cambr., Trans. Linn. Soc. xxvii., p. 45, 

 pi. lvii., No. 42. 



This spider is allied to Walchna'dra cristata, Bl., butmay easily be 

 distinguished, not only by its smaller size (the male measuring 

 no more than l-15th of an inch in length), but also by the form 

 of the fore part of the caput, and the structure of the palpi and 

 palpal organs. It is also less deeply and richly coloured. 



The cephalo-thorax is of a dark, rich, brown colour, and very 

 glossy. The caput of the male is elevated, and much porrected 

 in an upward, evenly sloping direction ; and is also divided into 

 two segments by a deep transverse notch or cleft ; but the hinder 

 Blope is far less abrupt than in Walckenmra cristata, and the two 

 segments (of which the hinder one is much the smallest) are less 

 pointed, and not nearly so conspicuously clothed (at their summits) 

 with hairs. The radial joint is considerably produced in front, 

 at its extremity, over the base of the digital joint, and has a row 

 of three short, black, sharp-pointed spines, near together, and 

 directed outwards not far from its extremity. 



Found in some abundance in May, 1863, under decaying 

 rubbish in a swamp at Bloxworth ; but I have never met with 

 it since. It has, however, been sent to me from more than one 

 locality in Scotland, and the North of England. 



WALCKENAERA ANTICA.

The male measures rather moro than 1 line in length, and the 

 female about 1-1 0th of an inch.
