“…While it is of interest to know that other ruminants such as the deer (Walker, 1954) conform to this pattern for ungulates, the real need now is to examine further species selectively. Thus it is important to know whether representatives of the Chiroptera or Insectivora can be classified with non-ungulates in this context, while there are some species, such as the American mole, that have important anatomical (placental) features common to ungulates but are, in zoological classification, removed from them.…”
