FOSSIL MAMMALIA. 109 



sufficient to convince the Baron of the identity of this palaeo- 

 therium with any of those of the Parisian environs. He rather 

 inchnes to believe it distinct. In the environs of Mon tabu- 

 sard, near Orleans, where, as we have mentioned, the bones of 

 lophiodons were found, were also found two species of the 

 palaeotherium, different from those of Paris. One must have 

 been rather smaller than the 'palceotherium crassum. Some 

 other debris, apparently of this species, were found near St. 

 Geniez, three leagues from Montpellier. A fragment of a left 

 lower-jaw, containing the four last molars, was found at more 

 than thirty feet deep, in a coquillaceous, hard, and compact 

 stone, which M. Cuvier supposes to be of fresh-water forma- 

 tion. Lastly, in the declivities of the Black Mountain, near 

 Issel, were also contained the bones of a palaeotherium, ex- 

 tremely similar to that of Orleans, and it is not improbable that 

 some debris found in this last place are referable to the species 

 of Issel. 



These species have been called by the Baron, Pal. Velaunum, 

 Pal. Aurelianense^ and Pal. Isselanum. The two last differ 

 principally from the others by the lower molars having their 

 intermediate re-entering angle divided in two at its summit. 



The Anoplotheria, up to the time in which the Baron's last 

 edition was published, were found only in the plaster-quarries 

 of Paris. We have noticed, in a preceding part of this article, 

 some subsequent detections of them. They have two characters 

 not observable in any other animal : feet with two toes, in 

 which the bones of the metacarpus and metatarsus remain 

 distinct, and are not soldered together as in the ruminantia, 

 and teeth in a continued series, without any intervening gap. 

 Man alone possesses teeth of this description, whose contiguity 

 is uninterrupted by any vacant interval. The anoplotheria 

 have six incisors in each jaw, one canine and seven molars, on 

 each side, as well above as below. The canines are short, and 

 similar to the outer incisors. The three first molars are com- 

 pressed, the four others in the upper-jaw are squared, with
