18 INSECTIVORA. 
Fraas (‘ Fauna von Steinheim,’ p. 4) referred Blainville’s specimens 
to another genus, under the name of Parasorex socialis. It appears, 
from a comparison of Gervais’s specimens with De Blainville’s figures, 
that the two belong to different genera, the former being really an 
Erinaceus. Under these circumstances it appears, on the whole, 
advisable to apply the name arvernensis to the Hrinaceus, and to take 
another specific name for De Blainville’s specimens, which are 
referred below to Plescosorew. 
27825. The nearly complete left ramus of the mandible, showing 
(fig.) all the teeth; from the Lower Miocene of Cournon (Puy- 
de-Dome), France. This specimen is the type, dnd shows 
all the teeth, which agree precisely with those of Hrma- 
ceus, especially in the small size of the last true molar and 
of the three teeth in front of pm, 4; it is figured by Gervais 
in the Zool. et Pal. Francaises, 2nd ed. p. 53, fig. 11. In 
size and form it is very like the mandible of some of the 
smaller Asiatic species’.
