the lower jaw containing the broader-plated tooth de-

to the other fossil Jaws of the Mammoth; they present 
the same specific differences from the Asiatic Elephant, 
and offer no modification that can be regarded as speci-

offers a great contrast with the preceding (fig. 92). 
The specimen (fig. 93), is the posterior part of a large

their digitated summits are longer, and advance further for-
