SECTION VII.- FINAL CONCLUSIONS

Thus we see that whether we take the Mammals in Geographical or in Systematic order, we arrive at nearly the same result-namely, that the best Primary Geographical Divisions of the earth are six in number. Of these the Australian Region (Neogæa), in which the Mammalfauna is pre-eminently Marsupial, and embraces the whole Order of Monotremes, is by far the most distinct. It is, however, also easy to separate the Neotropical Region (Notogæa), with its one family of Marsupials and numerous Edentates. The remaining Regions (Arctogæa), may be grouped together, but are still separable—on more slender grounds, it is true, into four divisions — the Ethiopian Region remarkable for its abundant Ungulates, the Giraffe, and the Hippopotamuses, the Oriental known by its Orangs, Gibbons, and Tapir, and the Palæarctic and Nearctic, which, no doubt, present many points of similarity as regards their Mammal-faunas, but may nevertheless be properly kept apart. The Nearctic Region, as has been shown above, has been overrun by an inroad from the northern portion of the Old World, but has a strongly developed under-stratum of endemic forms mixed up with some Neotropical types, which are utterly foreign to the Palæarctic Region.
