belluæ

Century Dictionary and Cyclopedia

1. In the Linnean system of classification (1766), the fifth of the six orders of the class Mammalia, containing hoofed quadrupeds with incisors in both jaws, and consisting of the four genera Equus, Hippopotamus, Sus, and Rhinoceros. It is occasionally used in a modified sense, corresponding to some extent with the Pachydermata of Cuvier, for the perissodactyl as distinguished from the artiodactyl ungulates, though the Linnean Belluæ included representatives of both these suborders of Ungulata.
