(Photo-micrograph by Geo. O. Mitchell.) itch-mite and the chigger are familiar examples of these degraded arachnids, and the wood-ticks, dog- and chicken-ticks are common examples of the larger blood- sucking forms. The body in both mites and ticks is very compact, the two body-regions, cephalothorax and ab- domen, being closely fused. The spiders have the abdomen distinctly set off from the cephalothorax. The eyes (fig. 93) vary in number and arrangement, the mandibles are large, each being com- posed of two parts, a basal hair-covered part, the falx, and a terminal smooth, shining, slender, sharp-pointed part,.
