GRISON (Galiclis vitlala), a carnivorous mammal, of the family Mustelidae, common in Central and South America and Mexico. It is about the size of a marten, and has the upper surface of a bluish-grey tint, and the under surface is dark brown. The grison lives on small mammals and birds, and in settled districts is destructive to poultry. Allamand's grison (G. allamandi) , with the same range, is somewhat larger. Another member of the genus is the tayra or taira (G. barbara), about as large as an otter, with a range from Mexico to Argentina. This species hunts in companies (see CARNIVORA).
