. Seaside studies in natural history. Marine animals. 44 MARINE ANIMALS OF MASSACHUSETTS BAT. Tlie Campanella. (Campaneltapachyderma A. Ag.) The Campa,nella (Fig. 51) is a pretty little Jelly-fish, not Fig 51 larger than a pin's head, reproduced directly from eggs, without passing through the Hydroid stage. During its early stages of growth it prob- ably remains attached to floating animals, thus leading a kind of para- sitic existence; but as its habits are not accu- rately known, this cannot be asserted as a constant fact respecting them. The veil in this Jelly- fish is very large, form- ing pendent pouches hanging from the cir- cular canal (see Fig. 61), and leaving but just room enough for the passage of the pro- boscis between the folds. It may not be amiss to introduce here a general account of this organ, which occurs in many of the Medusae, though it has very different pro- portions in the various kinds. It is a delicate membrane, hang- ing from the circular tube, so as partially to close the mouth of the bell, leaving a larger or smaller opening for the passage of the water, which is taken in and forced out again by the alter- nate expansions and contractions of the rig. 51.
