This spider may be easily distinguished from Linyphia ericoea, 

 Bl., by the coiled spine at the extremity of the palpal organs, as 

 ■well as by the pattern on the upper side of the abdomen. 

 From Linyphia pullata, Cambr., which it somewhat resembles in 

 pattern, it may be known by its lighter and yellower hue, as 

 well as by its much smaller size, and smaller and roundor digital 

 joint and palpal organs ; these last, although furnished with a 

 coiled, terminal spine, being quite different in other points of 

 structure. 



Occasional among heather towards the end of summer, and in 

 autumn, at Bloxworth. I have also received it from various 

 other parts of Dorsetshire, and it occurs in many localities in 

 England, Scotland, and Wales.

Linyphia exrbbta, Cambr., Trans. Linn. Soc. xxvii., p. 429, pi. 

 55., No. 23. 



The length of the male is l-8th of an inch. 



The cephalo-thorax is of a yellow-brown colour, and when 

 looked at sideways there is a hollow in the profile line just behind 

 the caput. The legs are long, slender, furnished with a few short 

 fine spines, and rather paler in colour than the cephalo-thorax, 

 The palpi are of a similar hue to the legs ; the radial and cubital 

 joints are of about equal length, the former being slightly 

 prominent behind, and somewhat obtusely produced at its 

 extremity in front. From near the fore extremity of the upper 

 side of both radial and cubital joints there projects from each a 

 single, long, strong, tapering bristle. The digital joint is not 

 very large, and has a lobe about the middle of the outer 

 margin ; the palpal organs are prominent and complex ; and 

 among the processes connected with them is one situated towards 

 their base on the inner side, projecting, prominently backwards 

 and outwards ; this process is of a slender form, nearly straight, 

 semi-transparent, and tipped with a kind of tuft of black bristles.
