CHAP, XL] THE ETHIOPIAN REGION. 273 
mammals are represented on the continent of Africa, only 11 of 
which occur in Madagascar, which also possesses 3 families 
peculiar to itself. The following is a list of all the genera of 
Mammalia as yet known to inhabit the island :—

We have here a total of 12 families, 27 genera, and 65 species 
of Mammals; 3 of the families and 20 of the genera (indicated 
by italics) being peculiar. All the species are peculiar, except
