DYSDERIDÆ.
A small family of spiders with only six eyes. They have also four breathing-holes in the front of the abdomen; but one pair leads to branched tubes instead of sacs. They are usually found under stones, with their legs drawn up close to their bodies, but can move very quickly when so inclined. Very few species are known, and none are common, in North America. [Fig. 7] is Dysdera interrita enlarged. Below are the eyes as seen from in front.
DRASSIDÆ.
A large family of spiders, varying greatly in shape, color, and habits. Most of them are dull colored, and live under stones, or in silk tubes on plants, and make no webs for catching insects. Their eyes are small, and arranged in two rows on the front of the head. Their feet have two claws and a bunch of flat hairs. The spinnerets are usually long enough to extend a little behind the abdomen. [Fig. 8] is a Drassus, and the eyes as seen from in front.

AGALENIDÆ.
Long-legged, brown spiders, with two spinnerets longer than the others, and extending out behind the body. They make flat webs, with a funnel-shaped tube at one side, [Fig. 24], in which the spider waits. [Fig. 9] is Agalena nævia, the common grass spider.
