HYDROIDS. 251 They are abundant in the spring. In the middle ofsummer they lay their eggs and perish. But the eggsdo not hatch Medusae like the parent, but each hatchesa little hydroid which is first free, then afterwards be-comes attached to a shell, seaweed, or stone, and fromthis little hydroid others branch till a little communityof hydroids had grown up, as in Figure 478. Fromthese hydroids bud again the Coryne, Figure 479. In some kinds, as Tubularia, Figure 481, the hydroidhas a wreath of coronal tentacles, as they are called,a projecting part called a proboscis, and the medusaegrow in clusters from just above the coronal tentacles. In those called Sertularians and Campanularians,Figure 483, the hydroid has a stem which is covered bya
