1. The Order Ungulata contains about 306 known species, arranged in seventy-one genera and thirteen families.
2. Ungulates are found all over the earth except in the Australian Region. In the Malagasy Sub-region there is but one species, which may possibly be a recent introduction.
3. Ungulates are most abundant in the Ethiopian Region, where 156 species occur. Of the great family Bovidae 138 out of 200 known species are restricted to this Region.
4. There are no Bovine Ungulates in the Neotropical Region, and only five (all nearly allied to recent or extinct Palsearctic forms) in the Nearctic Region.
5. In the Neotropical Region there are representatives of only four out of the thirteen families of Ungulates— Tapirs, Deer, Camels, and Peccaries.
6. There are no Deer (Cervidm) in the Ethiopian Region.
7. The New World has only 38 species of Ungulates against 270 found in the Old World.
DISTRIBUTION OF THE CETACEANS AND
In a previous chapter on this subject (Chapter VIII., p. 197) I have already stated the principal facts known respecting the distribution of these two marine orders of mammals and need not now repeat them. But I append a list of the genera with the approximate numbers of the generally recognized species and some general indications of their ranges, and I add some general deductions.
Table of the genera of the Order Cetacea, showing the approximate number of valid species and their distribution.
