For in the zoölogical system also these main-types of the invertebrates do not stand one above the other, but by the side of each other: at most, the radiata, the worms, the mollusca, and the articulata, take their places above the zoöphytes. Only within the main-types, in the classes, orders, etc., do differences in rank take effect; and even here, not without exception.
The central and intertropical parts of the Atlantic swarm with Pteropoda, Crustacea, and Radiata, and with their devourers the flying-fish, and again with their devourers the bonitos and albicores; I presume that the numerous lower pelagic animals feed on the Infusoria, which are now known, from the researches of Ehrenberg, to abound in the open ocean: but on what, in the clear blue water, do these Infusoria subsist?
Radiata, mollusca, feathers, flowers, ferns, mosses, palms, pines, grain-fields, leaves of cedar, chestnut, elm, acanthus: these and multitudes of other objects are figured on your frosty window; on sixteen different panes I have counted sixteen patterns strikingly distinct, and it appeared like a show-case for the globe.
Fishes, though most attractive, must be put in last; for as they are of the highest vitality, so they require the most oxygen and food, and hence should not be trusted until everything in the tank is well a-going. The first tenants should be the hardy varieties of the Sea-Anemones, or Actiniae, which are Polyps, of the class Radiata.
At the distance of half a mile, the vertical piles of pot-stones were much farther apart from each other. Dr. Buckland has described very similar phenomena as characterising the white chalk on the north coast of Antrim, in Ireland. Ventriculites radiatus, Mantell. Syn. Ocellaria radiata. D'Orbigny.
The earlier navigators who discovered it, and first told the astonished world that the substance which they had been accustomed to associate with the idea of the purest and most radiant whiteness had been seen by them lying red upon the ground, attributed the phenomenon to innumerable multitudes of minute creatures belonging to the order Radiata; but the discovery of red snow among the central Alps of Europe, and in the Pyrenees, and on the mountains of Norway, where marine animalcula could not exist, effectually overturned this idea.
In the following Silurian period we find corals, radiata, worms, mollusca, and crustacea, in great number, also all the main-types of the invertebrates; and in the highest Silurian strata there are also to be found representatives of the lowest class of vertebrates, of fish, but still of very low organization and little differentiated.
The sages of geology talked of the pre-Adamic eras, and of man's ending the slowly forged chain, of which the radiata form the lowest link; and then she was told that in those pre-Adamic ages paleontologists find no trace whatever of that golden time when the vast animal creation lived in harmony and bloodshed was unknown; ergo, man's fall in Eden had no agency in bringing death into the world; ergo, that chapter in Genesis need puzzle her no more.

No place could be more convenient for the observation of the Mollusca and Radiata than Cape Venus. At a few hundred paces from the shore is a coral reef, which at low water is completely dry. In the shoal water, between the reef and the shore, is found the greatest variety of the more brittle kinds of coral, and among their sometimes thick bushes, mollusca and echinodermes lie concealed.
