Cuvier describes two species of beaver found in allu- 

 vial strata. The one, \vhich is nearly allied to the castor 

 fiber, or common beaver, is found in France ; the other, 

 found on the shores of the sea of Azof by M. Fischer, 

 differs from the former, and is named castor trogontherium.

 but somewhat less than the common, is also described by 

 Cuvier, as occurring in the same limestone.
