Inappearance, they resemble certain plants, and one species iscalled the sea-nettle. 3. Radtata.—Another step upward brings us among theradiata, of which the star-fish is an example. The animals ofthis class are all inhabitants of the sea, and are distinguishedby a coriac^eous or calcareous investment. They are verysimply organized, but have tAvo openings and an intestinalcanal disposed in several convolutions, thus showing a decidedadvance beyond the preceding class. 4. MoLLUscA.—Coming to the oysters, clams, and other shell-fish, we find an alimentary apparatus forming a distinct organ, with several convolutions,a liver, and a circulatorysystem, having for its cen-ter a heart with one ven-tricle or chamber, and con-taining a watery rudiments of lungs inthe form of gills or of pul-monary tubes are also pres-ent. To this class belongsthe wonderful nautilus,the shell of which resem-bles a boat, and is used bythe animal as such.*. Fig. 867.—The Nautilus. as ii When the sea is cahn, groups of these animals may be seen navigatingthe surface of it, employing six of their tentacula as oars, and raising the AN ASCENDING SERIES. 593 5. Annulata.—Some naturalists place this class, which in-cludes the sea-worms, below the molkisca, but their oi-ganiza-tion is in some respects more complicated, and especially isthis observable in the circulatory system. 6. Insecta,—In the caterpillar we ascend into the insectworld, in which we meet the brilliant butterfly, the industriousbee, the fiery hornet, the fierce dragon-fly, the blood-thirstymosquito, and the destructive grasshopper. In this class thereis a complexity of organization corresponding with a highergrade of intelligence than we find in any of the foregoing divi-sions.
