The folk zoological taxonomy of the Nage people of central Flores (Indonesia) classifies wild mammals into thirteen named folk generic taxa (sensu Berlin). Of these, nearly half denote murids (rats and mice). In addition, Nage employ dhéke, a name that can specifically refer to large commensal rats, to further designate a folk intermediate taxon that subsumes other murid folk generics, thus resulting in a notably more elaborate classification of mice and rats than of other mammals. Murids also receive comparably distinctive treatment in other, special purpose forms of animal classification, and they occupy an especially prominent place in Nage symbolism. The paper considers how these several conceptual orders may be connected, including whether the ethnotaxonomic elaboration of murids may either reflect or be reflected in their symbolic value.
