IN NATURE for last year the writer gave a list of the localities for Testacella scutulum which had come under his notice. With a view to making this list more complete, and to obtaining a more definite idea of the distribution of the various species of the genus in the British Isles, the writer would be greatly indebted to any reader of NATURE who could forward to him, localised specimens of Testacella, alive, or preserved in alcohol, the present month being a likely one for the coming above ground of these slugs, which should now be found under logs and stones in the neighbourhood of rich garden soil.
