 the lower jaw containing the broader-plated tooth de- 

 scribed by Professor Nesti, are precisely similar in form 

 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-

 the plates, the smoothness of the sides of the line of enamel, 

 and the appearance of the digitated part of the plates even

 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-
