DENTAL SYSTEM 31 which the teeth were in the form of almost a quite simple cone; such a presumably primitive type of dentition being apparently retained among some existing Edentates, like the Armadillos, while it is possible that we should regard the dentition of the existing Cetacea (Fig. 2) as a reversion to the same primitive type. None of the Mesozoic mammals at present known exhibit this simple conical type of teeth, although we have an approximation to it in the extremely generalised genus Dromatherium. Starting then
