Certain confusions about the nature of biological classification and the logical difficulties arising from these confusions are discussed. A simple set-theoretic model for hierarchic classification is proposed. It is shown how the model enables us to define the terms commonly used in describing hierarchic classifications, and how theorems may be derived which correspond to the established rules of usage for such classifications. The ways in which the model can be developed to provide an underlying logic for numerical methods of classification are indicated.
