A radiological study of the developing dentition of the domestic albino ferret has revealed the presence of four upper and three lower deciduous functionless incisor teeth in each half of the jaw. The presence of the additional upper incisor tooth can only be accounted for in two ways:
(1) It arose as the result of a gene mutation within the closed colony.
(2) It is indicative of the fact that at some early date in the evolution of the Carnivora, four deciduous incisors were functional in each half of the jaw.
