Presented by Dr. Kaup. 



821 . The penultimate molar, right side, lower jaw, of the Dinotherium Cuvieri, 

 Kaup. 



The original was discovered in the miocene tertiary deposits at Che- 

 villy, in the plain of Beauce, near Orleans, and is described and figured 

 by Cuvier, as a molar of his second species of Gigantic Tapir, in the 

 ' Ossemens Fossiles,' 1822, torn. ii. pt. 1. p. 170. pi. iv. fig. 1.

822. The anterior portion of the right ramus of the lower jaw, with the canine 



and four anterior molars of the Lophiodon tapiroides, Cuv. (" Grand 

 Lophiodon de Buchsweiler"). The fourth molar has been displaced and 

 thrown inwards. The first of the three molars in place has two cusps, the 

 three following have each two transverse ridges, with this difference, that 

 in the second and the third the anterior ridge is raised and the posterior 

 one very low : in the fourth the two ridges are equal. The symphysis of 

 the jaw terminates opposite the interspace of the second and third molar. 

 The original was discovered in a quarry of freshwater calcareous 

 (eocene ?) tertiary formation near Buchsweiler in the Department of the 

 Lower Rhine, and is described and figured by Cuvier in the ' Ossemens 

 Fossiles,' 1822, torn. ii. pt. 1. p. 200. pi. 7. fig. 1.
