It was subdivided into bovina, cervina, giraffina, moschina, and camelina; also, a family of ruminating animals, consisting of species with simply rounded horns, which are not twisted in a spiral manner. There are no lachrymal sinuses. It contains the genera bos, bison, bubalus, etc. Ovibos (musk ox), generally ranked under bovidæ, is by some placed with the ovidæ. The oldest known are various species of bos, hemibos, and amphibos in the Upper Miocene of India. The genera bos and bison are found in the Pliocene.
