its base on the inner side, and another, much smaller, one on 

 the outer side ; the palpal organs are greatly developed and 

 complex, with various curiously-shaped prominent corneous 

 processes. 



The female is larger than the male, and is remarkable for the 

 large size and form of the process connected with the gonital aper- 

 ture. This process is a notable feature in the- female structure 

 of many spiders, but especially in that of fomales of the genus 

 Linyphia, and affords excellent characters for the distinction of 

 the species. 



Linyphia leprosa is one of our most abundant spiders, being 

 found plentifully nearly all the year round at Bloxworth, and in 

 other localities, in outbuildings of all kinds, lofts, faggot ricks, 

 wood stacks, holes and crevices in walls and trees, especially 

 where the latter are thickly overgrown with ivy. It appears 

 to be equally common throughout the south of England, and 

 is also found in Scotland. Different individuals (of both sexes) 

 often vary considerably in size, some being both larger and 

 smaller than the dimensions from above.

The length of the male is l-9th of an inch, and the female is 

 rather larger. 



This spider is closely allied to Linyphia leprosa Ohl., and 

 resembles it very nearly both in colours and markings. It is, how- 

 ever, generally rathor smallor ; though as Linyphia leprosa varies 

 considerably in size, probably the present species would be found 

 to vary also if a number of examples were compared together. 

 Among other distinguishing characters the following appear to 

 be the chief, and aro amply sufficient for the easy determination 

 of the species. The legs, which are occasionally annulated in 

 Linyphia leprosa, have no trace of annulation in any one of about 

 twenty examples examined. The palpi (of the male), on the cubital
