GENUS non det. 



M. 1492. Two fragments of the symphysial extremity of the right 

 ramus of the mandible, and a fragment of the maxilla, of 

 an Insectivore apparently allied to Erinaceus ; from the 

 Upper Eocene of Caylux, Prance. The specimens are too 

 imperfect to admit of certain determination.

48197. Two fragments of the mandible ; from the Middle Miocene 

 of Steinheim, Bavaria. A perfect cranium and mandible 

 are figured by 0. Fraas, in the ' Fauna von Steinheim,' 

 pi. i. figs. 2-5, under the name of Parasorex socialis. 

 The species differs from the genus Tupaia by the presence 

 of an additional premolar in both jaws, but is otherwise 

 closely allied, and it is not improbable that it should 

 really be referred to the same genus. Purchased, 1 877.
