ATTIDÆ.
The jumping spiders. The body is usually short, and the head square. The arrangement of the eyes is characteristic, [Fig. 11], a. The two large ones in the middle give these spiders a more animated look than those of other families. The legs are short, and the front pair often stouter than the others. They can walk easily backwards or sidewise, and jump a long distance. [Fig. 11] is the common gray jumping spider enlarged.

THOMISIDÆ.
The crab spiders. The body is usually flat, and wide behind. The front two pair of legs are longer than the others, and so bent that the spider can use them when in a narrow crack. Some of them, like crabs, walk better sidewise than forwards. Like the running and jumping spiders, they make no webs for catching food. The eyes are small, and simply arranged in two rows, [Fig. 12].
