This can bo only thoroughly explained by accurate figures 

 drawn from sovoral poiuts of view. The radial apophysis, 

 together with the structure of the palpal organs, which differ in 

 oach species, require very closo and correct observation and 

 comparison, to enable tho collector to form any trustworthy 

 determination of the very similarly coloured spiders of this 

 genus. Tho females closely resemble the males in colours and 

 general characters, and can bo readily distinguished only by tho 

 form of the genital aperture. 



Clubiona grisea is a rare spider among woods and debris of 

 various kinds in low damp places at Bloxworth, and in tho 

 neighbourhood, in spring and oarly summer. I have received 

 it in large numbers from the fens of Cambridgeshire. It is also 

 found in other parts of England, as well as in Scotland. 



CLUBIONA TEKEESTEIS. 



Clubiona tekrestkis, Westring, Aran. Suec., p. 395.

 pi. vii., fig. 76. 



Very nearly allied to Clubiona grisea, but of a brighter yellowish, 

 and rod-brown hue, clothed with rather sandy greyish hairs ; and 

 the abdomen has a darker tapering stripo along the middle of the 

 fore half. It may bo distinguished readily by tho form of tho 

 radial apophysis of the male palpus ; in the present spider this 

 is strong, of a crescent shape at its extremity, the anterior limb 

 of the crescent being the strongest ; and between the bases of tho 

 two limbs is a small dark proniinenco. The palpal organs have 

 a strong, sharp pointed spine, curved round bonoath their fore 

 extremity, and projecting on tho outer side. 



Clubiona terrestris is generally distributed throughout Great 

 Britain, and is not uncommon at Bloxworth and in many 

 other localities in this county ; it may be found among debris in 

 hedges, and in angles of walls, concealed in a slender, somewhat 

 tubular, silken web. The length of the female is rather over 

 4 lines, and the male is somewhat smaller.
