XXVII.—On the Mammals, Birds, etc., of the Mackenzie River District. By Bernard H. Ross, Esq.
Fort Simpson, McKenzie's River District.
10th November, 1861.
My dear Sir John,—I am happy to acquaint you that I have procured from the Youcon, through the kindness of Mr. Lockhart, who is in charge of that establishment, two teeth and three tusks of the Elephas primigenius, or what Prof. Leidy calls, in his "Ancient Fauna of Nebraska," Elephas americanus. Two of the tusks are moderately-sized portions; but they show clearly the great curve that distinguishes the fossil from the existing species of elephants. The third tusk is of much larger dimensions, not much decayed, and nearly straight. It possibly may belong to some other animal. How curious it is that a tradition exists up the Peace River of some immense animal.
If you do not require the specimens, after examination, might I suggest the British Museum as a proper place to deposit them in?
