I have taken specimens of Salticus gracilis among heath 

 gi'owing in woods on the Caernarvonshire and Denbighshire 

 sides of the valley of the Conway. 



Though M. Hahn has described the female only of this spe- 

 cies^ yet the figure he has given is that of an immature male.

There are several varieties of this spider, some of which have 

 been described by ai'achnologists as distinct species. Crevices 

 among accumulated fragments of I'ock occurring in woods in the 

 mountainous parts of Denbighshire and Caernarvonshire are 

 frequently selected for its abode, and afford it great facilities of 

 escaping from danger. In June the female incloses herself in a 

 cell of white silk of a compact texture, on the exterior surface of 

 which particles of soil, withered moss, and other materials are 

 sometimes sparingly distributed ; she usually attaches it to the 

 under side of stones or dead leaves, depositing in it from 20 to 

 30 spherical eggs of a pale yellow colour connected by fine silken 

 lines.
