内容简介: 《糖心app登录失败》the African being round and convex in all its parts. The teeth of the former are composed of transverse vertical lamin? of equal breadth, while those of the latter form rhomboidal or lozenge-shaped divisions. The ears of the Asiatic are also smaller and descend no lower than his neck, and he exhibits four distinct toes on his hind feet: the African on the contrary is furnished with ears of much greater size, descending to his legs, and no more than three toes are visible on his posterior extremities. These differences are so striking and important, and indeed, so far as regards the form of the head and the structure of the teeth, so essential, that it is impossible not to adopt the division which has been founded upon them, and to consider the natives of the two continents as originally and specifically distinct.From the strongly marked group, to the illustration of various species of which the foregoing pages have been dedicated, we pass by a natural and easy transition to an animal, which, although closely resembling them in its zoological characters, and in the cowardly ferocity of its disposition, bears nevertheless a stronger affinity to the dogs, with which it was associated by Linn?us. From each of these groups it is, however, readily distinguished by several obvious and essential characters, of sufficient importance to sanction its separation as a genus, now universally adopted among naturalists.
