strongish prominent denticulations ; the cephalo-thorax also lias 

 a marginal row of similar denticulations. The palpi (of tlie male) 

 are long and slender, the third (or cubital) joint has a strong and 

 nearly porpendicular, pointed spur beneath its fore extremity ; and 

 the second (or radial) joint is broad, obtuse, and 

 rather rounded at the, somewhat produced, fore extremity 

 of the upper side. Tho colour of the cephalo-thorax is a rich 

 glossy, brown-black ; the legs reddish-brown, and tho abdomen 

 black; the humeral (or longest) joint of the palpus (in all 

 tho three species) is armed with denticulations ; and, in the 

 present one, there is frequently a longitudinal, central row of 

 very small, sharp denticulations on the caput. 



This is an abundant spider in most parts of England ; and 

 especially in early summer and autumn, when, after a frosty 

 morning, and gossamer lines are numerous over the grass fields, 

 numbers of both sexes may be found running on the silken 

 threads.

This spider is a little larger than the foregoing, but resembles 

 it vory closely in form, structure and colour. It may, however, 

 be recognised, without much difficulty, by the last joint but one of 

 the male palpus, which, instead of having the produced portion, 

 at the fore extremity of tho upper side, broad and obtuse, has 

 that part rather more produced, and somewhat pointed. It 

 is f ound in the same localities and at the same periods as Neriene 

 atra, but is a much rarer spider, especially in Dorsetshire, where 

 I have only met with it on two or three occasions,
