If an insect, a spider, a- scorpion, a centipede, or a lobster be examined, the body will be found to be composed of a series of more or less similar rings or seg- ments joined together; and some of these segments will be found to bear jointed legs (Fig. i). All the animals possessing these characteristics are classed together as the Branch Arthropoda, A similar segmented form of the body is found among worms; but these are dis- tinguished from the Arthropods by the absence of legs. It should be remembered that many animals commonly called worms, as the tomato-worm, apple-worm, etc., are, not true worms, but are the larvae of in- sects (Fig. 2). The angle-worm is the most familiar example of a true worm. The Branch Arthropoda is the largest of the branches of the Animal Kingdom, including many more known species than all the other branches taken together. Our common representatives are distributed among four classes: these are the Crustacea, the Arachnida, the Myriapoda, and 'the Hexapoda. The 9.
