On the structure of the dental tissues of marsupial animals, and more especially of the enamel

Abstract The author of this communication, after examining microscopi­cally the teeth of many marsupial animals taken from the majority of the families that make up the order Marsupialia, finds that they possess a structural character by which they may be distinguished from other mammalian teeth, subject only to one of two exceptions; In which exceptions, however, the teeth are small and may readily be distinguished from marsupial by their external character. They are the teeth of the Hyrax Capensis, the British Shrews, and the molar teeth of the Jerboa. The author states, that so far as he has had opportunities of ex­amination, the teeth of the various species may also be distinguished, the one from the other. He points out, for instance, that, on com­parison, the teeth of Dasyurus ursinus may be distinguished from the D. macrourus.
