Defunct Linnaean taxonomy. 19th-century artworks of mammals and reptiles 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 last two orders are shown; see image C017/8070 for the other five. The examples here are a giraffe, a chamois, a whale and a Grampus dolphin. The defunct Linnaean class 'Amphibia' is shown with two orders: Reptilia (alligator, chameleon, basilisk) and Serpentes (boa constrictor).
