Mr. Pratt on the Existence of the Anoplotherium 



bones may be identified with those of the freshwater turtle, consisting prin- 

 cipally of remains of the Carapax ; and two genera, at least, the Emys and 

 Trionyx, have been observed, corresponding with those described by Cuvier 

 as found in the Paris basin. Of the teeth, one is a molar of Palceotherium 

 magnum, another agrees with the first molar of PalcBotherium rninimum, and 

 the third is apparently part of a molar of Anoplotherium commune. Several 

 plates were found, which have proved to be the enamel plates of teeth of the 

 same class of animals, separated from their bony connexion ; and, as many of 

 these plates were observed, it is probable that the animals to which they be- 

 longed were numerous, although so few of their other remains have been found. 

 This may be partly accounted for from the marls in which they occur being 

 in general extremely fragile, and rarely containing a perfect shell; so that it 

 is difficult to separate the fossils from the marls without destroying the former. 

 I was also informed by a quarryman that he had several times observed large 

 bones, which had not been preserved, in consequence of their rotten state. 

 I have reason, however, to hope that in future such interesting remains will 

 not be lost to science, and that other genera of Mammalia may be discovered. 

 As proof of the justness of this expectation, I will next advert to part of the 

 lower jaw of a species of Ruminantia which was found in the lowest bed of 

 the marl, together with a single molar tooth belonging to another similar 

 animal. 



This jaw appears to be closely allied to the genus Moschus ; but the loss of 

 the anterior portion renders it difficult to class the fossil correctly, and the 

 greater width of the corocoid process distinguishes it from any described
