*The tooth supposed by Dr. Ilarlan to belong to this species, aud which he states is in the possession of Mr. 

 Wagner, I have seen, and am satisfied that it pertains to M. americanus. It is rather smaller than usual, but 

 the transverse angular hills, with the angular unobstructed valleys, are quite characteristic of the latter.
