[U] Pallas thinks that the saiga which is found in Hungary, Transylvania, Wallachia, and in Greece, is also to be found in the island of Candia; and he thinks that the _strepsiceros_ of Belon ought to be considered as such. Buffon, however, was not of that opinion, who referred the _strepsiceros_ of Belon to the class of sheep. THE GAZELLES, OR ANTELOPES. There have been thirteen species, or, at least, thirteen distinct varieties made of these animals; in this uncertainty, whether they are varieties, or species, we thought it best to treat of them all together, assigning to each a particular name. The first of these animals, and the only one to which we retain the generic name of _gazelle_, is the common _gazelle_, (_fig. 153._) which is found in Syria, Mesopotamia, and the other provinces of the Levant, as well as in Barbary, and in all the northern parts of Africa. The horns of this animal are about a foot long, entirely annulated at the base, lessening into half-rings towards the extremities which are smooth. They are not only surrounded with rings, but also furrowed longitudinally by small streaks. These rings mark the years of their growth, which is commonly about twelve or thirteen. The gazelles in general, and this tribe in particular, greatly resemble the roe-buck in the proportions of the body, natural functions, swiftness, and the brightness and beauty of the eyes. These resemblances would tempt us to think, as the roe-buck does not exist in the same countries with the gazelle, that the latter was only a degeneration of the first; or, that the roe-buck is a gazelle, whose nature had been altered by the influence of the climate and effects of food, did not the gazelles differ from the roe-buck in the nature of their horns; those of the roe-buck are a kind of solid _wood_, which fall off, and are renewed every year, like those of the stag; the horns of the gazelles, on the contrary, are hollow and permanent like those of the goat. The roe-buck has also no gall-bladder, which is to be found in the gazelle. The gazelles have, in common with the roe-bucks, deep pits under the eyes, and they resemble each other still more in the colour and quality of the hair, in the bunches upon their leg, which only differ in being upon the fore-legs of the gazelle, and upon the hinder legs of the roe-buck. The gazelles, therefore, seem to be intermediate animals between the roe-bucks and goats; but, when we consider that the roe-buck is an animal which is to be found in both continents, and that the goats, on the contrary, as well as the gazelles, belong only to the old world, we shall be induced to conclude that the goats and gazelles are more nearly related to each other, than they are to the roe-buck. The only characters peculiar to the gazelles, are the transversed rings and longitudinal depressions on the horns, the bunches of hair on the fore-legs, the thick streaks of black, brown, or red hair upon the
