The British Slugs

Abstract

MR. J. W. TAYLOR has just published part ii. of his admirable “Monograph of the Land and Freshwater Mollusca of the British Isles,” containing a discussion of the slugs of the genus Arion. It is a matter of interest that, notwithstanding the great amount of information gathered in recent years, the beautiful bicoloured varieties of A. ater appear to hold their own as truly endemic inhabitants of Britain. These are three in number, though Mr. Taylor treats the third as merely a subvariety.
