The eggs, of which the female may lay several hundred, consist of a germ en- closed in a tough coat or egg membrane. As the germ develops, tlie membrane finally bursts and a little wormlike creature emerges. Its bodj'' is made up of a numlwr of rings placed one behind the other. The first of the rings is the head and bears the biting jaws. Certain of the rings that follow bear legs which end in claws. ^ Lq}is, scale; petron, wiug. 29.
