In the preceding papers of this series, we have discussed the succession of animals in two types of aquatic habitats with particular reference to fish. While the data presented are only a minor part of those at hand they have served to illus-trate some of the principles of succession in aquatic habitats. Discussion of other aquatic situations would enable us to point out many more important facts but we must now pass to land habitats. To illustrate principles here we might discuss the development of either forest or prairie animal communities 59
