M. 1350. The nearly complete mandible, wanting the incisors and 

 the articular extremity of the left ramus ; from the Upper 

 Eocene of Caylux (Tarn-et-Garonne), France. This 

 beautiful specimen, in which the teeth are but very 

 slightly worn, agrees very closely with the one figured by

 fig. 10, but is slightly smaller, and the crowns of the two 

 middle premolars appear slightly higher.

 cheek-teeth of the right side except m. 3 ; from the Lower 

 Miocene of Sauvetat (Puy-de-D6me), France. Slight dif- 

 ferences can be detected between the premolars of this and 

 the last specimen. Croizet Collection. Purchased, 1848.

 Caylux. Purchased, 1848.

 from the Lower Miocene of Sauvetat. These specimens 

 are provisionally referred to the present species ; they are 

 somewhat larger than the corresponding teeth of the fore- 

 going specimen, but they are not larger than those of a 

 specimen figured by Filhol in the Ann. Sci. Geol. vol. vii.
