Studies in Tasmanian mammals, living and extinct. Number V. Zaglossus harrissoni, Sp.nov.

Among some fossil bones recently recovered by Mr. K. M. Harrisson, from a swamp upon King Island, we have found evidence of a giant Ant Eater, that exceeded very considerably in point of size the modern Monotreme. The evidence is furnished to us in the form of a nearly perfect right femur, and a very small portion of the proximal end of a humerus. We fortunately possess several femora of the modern animals, collected by Mr. L. L. Waterhouse in January, 1916, during a visit to King Island upon Geological Survey Work, and are therefore enabled to make a direct comparison between the Pleistocene, and the more recent Monotremes of that locality. Includes illustrative plate.
