subkingdom

1 The Embryophyta, or Metaphyta, are the most familiar subkingdom of green plants that form vegetation on earth.

2 It embraces several subkingdoms, and under these there are Classes, Orders, Families, Genera, Species, and sometimes intermediate groupings, all in regular subordination, but variously arranged by different writers.

3 These three classes or subkingdoms, as perhaps they might be termed from analogy with systems of biological classifications, are in technical language: 1.

4 The communication between individuals is especially characteristic of vertebrates, and in the higher members of that subkingdom it plays a very great r�le in aiding the work of consciousness.

5 In the Cambrian, Ordovician, and Silurian the invertebrates were represented in all their subkingdoms by a varied fauna.

6 The "hundreds" make up the province or subkingdom.

7 As compared with later faunas, the animals of the Cambrian were primitive, but their diversity—every subkingdom of invertebrates being represented—is positive evidence that they were not the first inhabitants of the waters.

8 This subkingdom includes two classes of interest to the geologist,—the HYDROZOA, such as the fresh-water hydra and the jellyfish, and the CORALS.

9 This subkingdom comprises at present such familiar forms as the crinoid, the starfish, and the sea urchin.

10 Much or all of this vast differentiation was accomplished before the opening of the next era; for all the subkingdoms are represented in the Cambrian except the vertebrates.
