Succinea elegans Risso new to the Orkneys, —Amongst a few common 

 species of shells which I received recently from the Orkneys are examples of 

 Succinea ekgans. These have been verified by Mr. J. W. Taylor, and the Recorder 

 tells me that it is a new record for vice-county iii. — J. R. le B. Tomlin {Read

Vertigo angustior Jeff, in Hertfordshire. —In February, 1911, I noticed that 

 in the earth cast up by moles in the low-lying pastures which border the large 

 reservoir at Wilstone, near Tring, there were many bleached shells of mollusca. A 

 section exposed by a ditch which traversed one of the meadows showed that the 

 thin layer of alluvium overlying the chalk was crowded with shells. The associated 

 species suggested that the construction of the reservoir about a hundred years ago 

 had entirely altered the character of the place, transforming swampy ground into 

 comparatively dry meadow land, and, incidentally, destroying the habitat of the 

 mollusca. An hour's search in the mole-hills yielded two specimens of Vertigo 

 angusiior, many V. pygmcea, V. antivertigo, Janiinia viusconim, Vallonia 

 excentrica, Hygroniia hispida, Succinea elegans and Cochlicopa liibrica. In smaller 

 numbers, but conspicuous owing to their larger size, were Helix nenioralis and 

 Htlicigona arbiistortim var. alpesiris, whilst Succitiea pittris And. Limncsairuncaitda 

 were not uncommon. I found two specimens of Cacilioides aciciUa and a few 

 Euconulus fnlvtis^ Caiychium minimum and Pisidium casertanum. — Chas.
