This species was first described by LinnEeus, but was afterwards generally confounded with the common Vole of the continent, and thus A. agrestis and A. arvalis are constantly given as synonymous, although the animals are very distinct in nature. A. agrestis may always be dis- tinguished by the character of its second upper molar, which laas five cemental spaces, whereas the same tooth in A. arvalis, as in all the other European Voles, has only four spaces. It seems not a little strange that the last-named.
