ramus of the mandible, and a fragment of the maxilla, of 
an Insectivore apparently allied to Hrinaceus; from the 
Upper Eocene of Caylux, France. 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 O. Fraas, in the ‘ Fauna von Steinheim,’ 
pl. i. figs. 2-5, under the name of Parasorex  socialis. 
The species differs from the genus 7’upaia 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, 1877.
