Extract

In addition to the localities in Europe and N. America, another area for Tertiary Mammals has in very recent times been laid open to view in the Southern part of Argentina, which promises in the wealth of its contents to exceed those previously known. A few scattered remains from the Tertiary beds of the neighbourhood of Santa Cruz in Patagonia were already known more than forty years ago, but it is only lately, through the work of Burmeister and Moreno, and more particularly through the indefatigable researches of Florentino Ameghino, that a more complete insight into this very remarkable fauna has been obtained.

page 457 note 2 The examination of a great number of lower jaws and detached teeth of the genera Abderites, Acdestis and Eponorthus, which I owe to the kindness of Señor Ameghino, shows that the molars in these genera do not agree, either in number or in form, with those of Neoplagiaulax. They greatly resemble those of the Australian Hypsiprynmidsæ, and they are proved to be genuine Marsupials by the incurved angle of the lower jaws. Ameghino also acknowledges them (Revue génér. des Sciences, 1893, p. 77Google Scholar) as Diprotodout Marsupials, to which he also further assigns Plagiaulax, Neoplagiaulax and Ptilodus.
