CASTORTDJE. 219 



35747. Fragments of the mandible, showing the cheek-teeth of both 



sides ; from the Lower Miocene of Germany. The pre- 

 molar is of the same size as that of No. 26707, but the 

 true molars are larger, and are also slightly larger than 

 those in the specimen figured by Filhol, loc. tit. The 

 length of the space occupied by the first three cheek-teeth 

 in this specimen is 0,0165, and in No. 26707, 0,0155. 



Purchased, 1865. 



35748. Part of an incisor ; from the Lower Miocene of Harlach, 



near Him, Wiirtemberg. Purchased, 1865. 



31064. Part of the left ramus of the mandible, with the four cheek- 

 teeth ; from the Lower Miocene of St. Gerand-le-Puy. 

 The teeth are slightly smaller than those of No. 40897, 

 the length of the first three being 0,0135. The differ- 

 ence in the size of this specimen and No. 35747 is very 

 considerable, but the other specimens afford such a tran- 

 sition, that it appears impossible to separate them. 



Bravard Collection. Purchased, 1852. 



31063. Part of the right ramus of the mandible, agreeing in size 

 with the last ; from the Lower Miocene of St. Gerand-le- 

 Puy. Bravard Collection. Purchased, 1852. 



31062. Part of the left ramus of the mandible of an immature in- 

 dividual, containing the milk-molar and the three true 

 molars ; from the Lower Miocene of St. Gerand-le-Puy. 

 This specimen agrees in size with the two last.

40901. The right humenis, wanting the head ; from the Lower 

 Miocene of Allier. This specimen is similar to one figured
