Finally? in the original memoir? descriptive of this 

 supposed new genus? the author has himself expressed 

 doubts of the validity of the characters on which it is 

 proffered. He admits that the specimens he has de- 

 scribed are the remains of a young individual? and that? 

 u in every view? this animal so strongly resembles the 

 Mastodon? but for the singular difference of organization 

 presented by the lower jaw and its tusks? we could not 

 avoid concluding we had obtained a young animal of 

 that species." As regards this jaw itself and molar 

 teeth? they certainly do resemble those of the Mas- 

 todon giganteum, as closely as the same parts in any 

 young animal resemble those of the adult individual. 



Note. — Mastodon angustidens, Cuv. and M. tapiroides, Cuv. Indications of 

 the existence of these species in North America, were given in the Fauna Ame- 

 ricana, pp. 212, 213. Subsequent observations have not yet further confirmed 

 this indication.

Locality. — In Europe these remains abound in the

 They are scattered over a vast range of country in North

 mals have been found enveloped in ice on the north
