INTRODUCTION
The greater grison (Galictis vittata), a member of the Order Carnivora, Family Mustelidae, is one of two species within the genus Galictis; the other is the lesser grison (Galictis cuja). As a result of the uncertain morphological distinction between these two species, the geographical distribution of these taxa has discrepancies in the literature. The range for the greater grison apparently extends from the extreme northeastern of the Neotropics in Mexico to the central region of South America (including the south of Peru, Bolivia, southern Paraguay, and northeastern Brazil). Only in southern Paraguay does the distribution of the greater grison partially overlap with the northwestern limit of the distribution of the lesser grison, which occurs from the extreme south of Peru, southern Bolivia, and northeastern Brazil to southern Chile and Argentina.
