168 CATALOGUE OF THE MAMMALIA OF 
mortality, which chiefly occurs in August, we think, deserves 
enquiry.

This species is larger and more robust than the foregoing, has 
a broader snout, much larger feet, especially the fore ones, and 
is, we think, in our district, as on the Continent, the commoner 
species. It affects more moist localities. The dentition is the 
same as in S. hibernicus.
