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. 140.

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. 163. Chthonius rayi, L. Koch. River Wandle. 185
