These polyp-heads bear the mouths, and each is surrounded by two rows of tentacles which wave through the water intent upon the capture of the small marine animals upon which the Fennaria feeds. Jelly- fishes grow out from the sides of tlie polyp-heads, and within these the eggs develojJ At times the eggs are cast out before the jelly- fishes are set free, but often the jellyfish escapes from the hydroid and sAvims about, car- rying its eggs with it. The eggs then develop into little pear-shaped larvaj which swim rapidly through the water but soon settle down and change into tree-like hydroids which in turn develop another genera- tion of jellyfislies. In spring and early sum- mer large, pale colored, stocks of Pennaria are found upon rock weed, piles, etc.; but about tlie middle of August small, highly colored stocks, with pink heads, are found in great abund- ance upon eel grass. This was observed by Professor Hargitt in "The American Naturalist," Vol. XXXIV, p. .390. The iSea Plume, fOhelia coiii- iiiissinxihs, Fig. 14), is common upon tlie wooden posts of wharves or attached to stones or sea-weed. The main stems are fully six inches long, and they give rise to spirally arranged branches which run nearly at right angles to the stem. The creature thus resem-.
