The importance of teeth in the classification of animals, from the days of Aristotle, Ray, Linnæus, Erxleben, Hunter, and their numerous successors, caused the occurrence of abnormalities to be frequently noted. Such, indeed, are found in many groups, e.g. in the Primates, Lemurs, Carnivores, Rodents, Ungulates, Sirenians, Edentates, and Marsupials. Whilst the main subject of this investigation was abnormal teeth in the rabbit, it was thought right to glance at the other groups of mammals, including various rodents besides the rabbit, so as to give greater breadth to the observations. Less attention, perhaps, was paid to the diminution or increase in the number of the teeth in the general groups than to their abnormality in structure or position.
