jaw with a grinder, M. Cuvier hesitates at determining this tooth to he- 

 long to an animal of this genus. 



With these teeth, which are rather smaller than those of Pal&othcrmm 

 medium, two fragments of os humeri, very closely corresponding, as to 

 size, were also found. 



The remains of another species, approaching to the palaotherium, was 

 found by the Professor Herman, of Strasbourg, in the department of the 

 Lower Rhine, in the mountain of Saint Sebastian, one of the lowest in the 

 chain of Vosges, in a calcareous bed mixed with fresh-water shells, and 

 what is very remarkable, covered, as in the beds of gypsum which contain 

 the palaotherium in the neighbourhood of Paris, with several beds full of 

 marine productions. This animal, like the pal&otherium, had both canine 

 and incisive teeth, but it had one molar tooth less, and had not the space 

 which in the paUeotherivm exists between the first molar and the canine 

 tooth. The other observable specific characters of the lower as well as 

 of the upper jaw, leave no doubt that the animal to which these teeth 

 belonged nearly approached to the paltea&er&m. 



Having placed before you a sketch of the interesting discoveries re- 

 specting the genus Palaotherium, I shall proceed to give you a slight view 

 of the discoveries respecting those animals whose remains were found 

 with these, but which did not possess canine teeth : to the genus com- 

 prising which was given the name Anoplotherium. 



It has been already remarked, that among the teeth which Cuvier 

 had discovered, some of the grinders appeared to belong to an animal 

 which had no canine teeth. These grinders, which were thought to 

 somewhat resemble those of the Palaotherium, are found to differ from 

 them in the following respects. The outer surface of the lower grinders 

 has not cylindrical, but conical convexities, narrowing very much up- 

 wards. These convex portions are three in number in the last grinder, 

 and two in the two next. Towards their base, their curve becomes 

 double ; that is to say, that they are convex, not only transversely, but
