those of Clubiona holosericea. The female deposits about 145 

 spherical eggs of a yellowish white colour, not agglutinated 

 together, in a lenticular cocoon of white silk of a fine- texture, 

 measuring T 3 jjths of an inch in diameter. This cocoon, for which 

 she manifests much solicitude, is inclosed in a cell of white silk 

 fabricated on the inferior surface of a leaf, the sides of which are 

 curved upon it and are retained in that position by silken 

 lines. Towards the end of June or the beginning of July the 

 eggs are hatched ; but the young, like those of all other spiders 

 whose ceconomy is known, do not quit the cocoon till they have 

 completed their first change of integument.

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

 the usual haunts of Clubiona epimelas, which is found, though 

 rarely, in the wooded parts of Denbighshire and Caernarvonshire. 

 The male has the palpal organs completely developed in May, 

 and in J une the female constructs a plano-convex cocoon of white 

 silk of a very fine texture, measuring T 5 oths of an inch in dia- 

 meter, in which she deposits about 154 spherical eggs of a pale 

 yellow colour, not agglutinated together. The cocoon is attached 

 by its plane surface to the under side of a stone or leaf, and is 

 inclosed in a sac of white silk, which also comprises the female.

In the wooded parts of Denbighshire this spider is found 

 among ivy and lichens growing on trees. It spins a large sac of 

 white silk on the under side of leaves or behind exfoliating bark, 

 in which the female constructs a cocoon of a lenticular form in 

 the month of July ; it is composed of white silk of a very fine 

 texture, is T 3 n ths of an inch in diameter, and contains between 30 

 and 40 spherical eggs of a pale yellow colour, not agglutinated 

 together.
