These dimensions are slightly larger than those of the two teeth figured by Gervais and regarded as m. 1 and m. 2 ; but it is quite probable that they are really mm. 4 and m. 1. The present teeth are readily distinguished from those of H. hovinus by their inferior size, and their lower cusps, shallower hollows, and the slighter concavity of the outer surface of the outer columns. They are really intermediate between the molars of H. hovinus and A. alsaticum (Ho. M. 1389); but are, on the whole, nearest to the former. Hastings Collection. Purchased, 1855. 29793.
