The gazelles and chevrotains inhabit only the hottest countries of the Old World; they cannot exist in temperate climates, and still less in those that are cold. They could not, therefore, have ever frequented the northern countries, and have passed, by that means, from one continent to the other; nor have any travellers or historians of the New World, ever pretended to have seen them in that part of the globe. On the contrary, stags and roe-bucks, which inhabit cold and temperate climates, might have passed over the northern lands, and therefore are met with in both continents. We have observed, in our history of the stag, that the Cardian stag is the same as that of Europe; that he is only smaller, and has some slight variations in the shape of his horns and the colour of his hair. We may add, to what has been already said, that in America there are as many varieties among stags as in Europe, notwithstanding which they are of the same species. One of these varieties is the Corsican stag, which is smaller and browner than the common kind. We have also mentioned white stags, and hinds, and have said, that this colour proceeds from their domestic state; this kind is also found in America, as well as our common and small brown stags. The Mexicans, who keep these white stags in their parks, have denominated them _Royal Stags_. It is a native of Germany, and commonly called the _Stag of Ardennes_; and _Brandhirts_, by the Germans: it is at least as big as the large French stags, but differs from them by several particular characters. Its coat is thicker, and of a lighter colour under its belly: its throat and neck is furnished with long hairs, like the he-goat, which has caused both ancients and moderns to give it the name of _tragelaphus_, or _stag-like goat_. There are also a great number of roe-bucks in America: we are only acquainted with two varieties in Europe, the red and the brown; the latter are smaller than the former, but they perfectly resemble each other. The mazame of Mexico, the cuguacu-apara of Brasil, and the cariacou, or forest hind of Cayenne, entirely resemble our red roe-bucks. Comparing the descriptions given of them is a sufficient proof, that all these names denote the same animal. But the temamaçame, which we suppose to be the cuguacu-été of Brasil, the small cariacou of Cayenne may be a variety different from those of Europe. The temamaçame is less, and whiter on the belly than the mazame, in the same manner as our brown roe-buck has a whiter belly, and is smaller than our red one; it seems also to differ by the horns, which is single and without antlers in the figure given by Recchi; but if we consider that our roe-bucks, and stags, have no antlers in the first, and sometimes even in the second year of their age, we shall be inclined to think, that Recchi's temamaçame was too young to have antlers: these two animals, therefore, appear to be only simple varieties in the roe-buck species.
