those of the Indian species by more than one-fourth, and those of the 

 American Tapir by nearly one-half. 



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. 206. pi. ~. fig. 3. 



Presented by Baron Cuvier. 



824. The crown of an incompletely developed superior molar tooth of the 



Lophiodon tapiroides, Cuv. The original is figured in the ' Ossemens 

 Fossiles,' J 822, torn. ii. pt. 1. pi. 1, and is described in the posthumous 

 edition of the same work, 8vo, 1835, as " Germe de dent d'origine incon- 

 nue, qui parait appartenir a la grande espece de Lophiodon de Buch- 

 sweiler." Presented by Baron Cuvier. 



825. A cast of the middle part of the left ramus of the lower jaw of a Lophiodon 

 with the last three or true molars, and part of the premolar next in ad- 

 vance. The crowns of all these teeth appear to have been worn down by 

 mastication almost to their base, but they have precisely the proportions, 

 and the last molar retains the anterior of the two transverse ridges, 

 which characterize the teeth of the genus Lophiodon, Cuv. The last 

 molar tooth likewise possesses the large posterior lobe or talon which 

 distinguishes this tooth in the Lophiodon from that of the Tapir. The 

 teeth a little exceed in size those of the Lophiodon Isselanus (Grand Lo- 

 phiodon dTssel), Cuvier, 'Ossemens Fossiles,' ed. 1822, torn. ii. pt. ]. 

 p. 184. pi. 3. fig. 3, the antero-posterior diameter of the last molar in that 

 species being one inch eight lines and in the present fossil one inch ten 

 lines. But the depth of the jaw below the middle of the last molar in 

 the present fossil is three inches ; whilst that in the Lophiodon Isselanus, 

 in the figure cited, is scarcely two inches, and Cuvier expressly states 

 (p. 186) that it surpasses in depth the corresponding part of the jaw 

 of the Lophiodon medius (pi. 3. fig. 1.), which has molar teeth of the 

 same size as in the Loph. Isselanus. I propose, therefore, to name the 

 American extinct species of Pachyderm indicated by the present fossil,
