130 DISTINCTION IXTO SPECIES. 



Mastodon 1st, by tlie length of the lower jaw; 2c?, by the existence of four ridges in 



Longiros- 



tris. the third, fourth, and fifth teeth ; and by various other points. Professor 

 Kaup has so well described what relates to the Mastodon Longirostris as 

 to render it quite unnecessary for us to enter into any description or inves- 

 tigation in regard to it. 



Were it admissible, we should have much to say on the Eppelsheim 

 fossils. Having, through the aid of Professor Kaup, obtained beautiful 

 casts of the collection, we have been enabled to use it with great advantage 

 in the course of our necessary investigations, embracing, as it does, about ■ 

 fifty specimens belonging to Mastodon Longirostris, and thirty specimens 

 of Dinotheriuin, as well as other fossils. 



Under the head of Mastodon Longirostris may be placed, according to 

 Professor Kaup, the Mastodon Arvernensis found in the south of France by 

 Croizet and Jobert, in 1828. This supposed species is said by M. De 

 Blainville to be characterized by a greater number of mammillary eminences 

 than other species, and by a talon in front' as well as behind. Few authors, 

 however, admit it to be a distinct species ; and Professor Kaup considered 

 it to be the young of Mastodon Longirostris. M. Laurillard, on the other 

 hand, believes it to be a Mastodon Angustidens. 



MASTODON SIVALENSIS. 



M^todon This is a new species from the sub-Himalaya Mountains, established 



by Dr. Falconer and Captain Cautley. The teeth are of great size. An 

 ultimate molar, belonging to the upper jaw, measures in length a little over 

 eight inches, and in width three inches; another, belonging to the lower 

 jaw, measures nine inches and a half in length, by three inches and four-
