perceptibly, to the spinners. Ventral area black, with a 

 central series and two lateral series of dull pale guttulte. 



Sternum deep sienna-brown, with a pale lozenge-shaped 

 central disk. 



Epigyne of female consisting of a large red-brown, shiny, 

 chitinous plate, narrow in front, springing from a transverse 

 oval chitinous cup, dilating posteriorly, forming a large trian- 

 gular plate, whose posterior angles are produced and slightly 

 procurved. The posterior margin is often a little emarginate, 

 and a broad furrow or depression runs through the middle. 



This portion of the structure is exceedingly variable. It is 

 impossible to give a figure which will represent all the forms, 

 differing somewhat as they do in every specimen. 



The same variability is noticeable also in the females of 

 the closely allied species, monticola and palustris. 



Palpus of male large. Femoral joint black at base, pale 

 yellow at apex ; patella pale yellow ; tibite black, clothed 

 with long hairs ; tarsus deep black, clothed with black hairs, 

 veiy large (larger in proportion even tlian in palustris) ^ fur- 

 nished with a claw at apex. The bulbous process at the base 

 of the organs is very prominent, and the organs differ in 

 character from those of closely allied species, it is, however, 

 so difficult to examine this structure that, since there are other 

 infallible characters for determining the identity of the species, 

 it is scarcely worth while to make a very elaborate analysis 

 of them. 



This fine Pardosa belongs to the group which includes 

 herhigrada, monticola^ and palustris. There is, in reality, no 

 difficulty in distinguishing them from each other, 



Tiiis species, one of the largest of the ^'Pardosas,^^ was 

 exceedingly abundant on the western shores of Poole Harbour 

 in May 1894. They were found very close to the water's 

 edge, lurking beneath the rushes, running swiftly over the 

 herbage during gleams of sunshine. The long hairs on the 

 legs give them quite a feathery appearance, even when 

 running, while the large size and black colour render them 

 very distinct from any other species of the genus. Though 

 more nearly resembling in general appearance j^^^^ustris, yet 

 the form of the epigyne and the slender tarsi of the first pair 

 recall rather monticola, while j^'^^f^^tris, not indeed in general 

 appearance, but both by the form of epigyne and by the 

 dilate tarsi, seems more nearly allied to herbigrada.
