214 "^"E SPIDERS OF EPPIKG FOREST. 



also. Legs short, strong, adapted for leaping, not greatly spinose, those of the 

 first and second pairs being often abnormally developed. Tarsal Clarvs, two, a 

 claw-tuft being present. 



This is perhaps the most sharply-defined of the spider-famihes^ 

 its representatives being easily recognised by the arrangement 

 of their eyes and by their saltatorial habits. Many of the species 

 are brilhantly coloured, and are in some cases ornamented with 

 beautiful iridescent scales. The Salticidae are for the greater 

 part inhabitants of the warmer regions of the globe. Thirty-four 

 species are recorded as British, but Epping Forest has, up to the 

 present, furnished us with only ten, representing eight genera.
