SPIDERS 



The members of this family have eight eyes, situated in very much the same position as 

 those of the Argiopidte, but the mandibles are usually weak, the maxilla are inclined over the 

 labium, and the posterior legs have a comb of stiff curved spines beneath the tarsi. The web 

 consists of a tangle of crossing lines, and the spider often constructs a tent-like retreat wherein 

 the egg-sac is hung up. Tarsal claws, three. The legs are devoid of spines.

CHERNETES 

 CHELIFERID^E 



Out of twenty species of false scorpions hitherto recorded as indigenous to Great Britain 

 only one has been taken in this county. The various species can usually be found amongst 

 moss and dead leaves, or beneath stones and the bark of trees. They are unmistakable on 

 account of their possession of a pair of forcipated palpi, like those of the true scorpion.
