Note 3 — BOOK IV.
Reading edition
In his History of Animals, (b. i. c. vi.), he says, that the great classes of animals are Quadrupeds, Birds, Fishes, Whales (Cetaceans), Oysters (Testaceans), animals like crabs which have no general name (Crustaceans), soft animals (Mollusks and Insects). He does, however, call the Crustaces by a name (Malacostraca, soft-shelled) which has since been adopted by Naturalists.
