in colour.
Limax agrestis, L. Ditto, in gardens and fields ; variable

Family TESTACELLIDAE.
Testacella scutulum, Sow. 1823. In old gardens at
Wanstead; fairly abundant. [More commonly known as T. haliotidea,
Drap., but Mr. J. W. Taylor, F.L.S., has, I consider, conclusively

Helix aspersa, Muller. Plentiful everywhere. Among the
many hundreds of the common snail which I have looked over, I
