Defunct Linnaean taxonomy. 19th-century artworks of a range of mammals classified according to now mostly defunct Linnaean taxonomy. The system shown here had seven orders of mammals: Primates, Bruta, Ferae, Belluae, Glires, Pecora and Cete. Examples of the first five orders are shown, with the other two orders shown in image C017/8071. The three primates here (across top) are: an ape, an orangutan and a lemur. The other four animals are a seal (Ferae), a rhinoceros (Bruta), a hippopotomus (Belluae), and a flying squirrel (Glires).
