of a plano-convex figure, attached to the under side of stones by its plane sur- 

 face ; it is of a fine but very compact texture, and measures |ths of an inch in 

 diameter : when newly constructed it is white, but becomes reddish before it 

 is abandoned by the young, which, at that early period of their existence, have 

 each inferior mammilla provided with two large and two small papilla?. The 

 female usually remains upon or near the cocoon, to which she is strongly at- 

 tached.

Crevices in stone walls, and the under side of fallen leaves, are favourite 

 haunts of Clubiona epimelas, which is found, though rarely, in the wooded 

 districts of Denbighshire. The male has the palpal organs completely deve- 

 loped in June. In July the female constructs a plano-convex cocoon of white 

 silk, of a compact but very fine texture, measuring ^ths of an inch in diameter, 

 in which she deposits about 150 spherical eggs of a pale yellowish white colour, 

 not agglutinated together. The cocoon is attached by its plane surface to the 

 under side of stones, and is enclosed in a sac of fine white silk, which also in- 

 cludes the female.

This active spider occurs on trees in the woods of Denbighshire and Caernar-

 trunks and branches.

Specimens of this handsome species have frequently come under my obser- 

 vation when exploring the woods and commons of Denbighshire. In July the 

 female constructs a cell of white silk, of a fine compact texture, among the stems
