Helix cantiana Montagu at Tooting Common, Surrey.— I am not able to 

 trace that Helix cantiana has ever been set down as occurring at Tooting Common 

 — that is actually in London, and within five miles of Charing Cross. As, however, 

 it will in all probability sooner or later be reported from thence, I think that the 

 fact, positively known to me, that it has (quite innocently) been introduced there 

 recently, in 1901, should be placed on record. A young friend wrote to me, in 

 1902 : " My colony of Helix cantiana on Tooting Common is flourishing." This 

 was the first intimation I had of the matter, and I at once asked for particulars, 

 explaining at the same time the scientific importance of placing them on record. 

 My friend replied : "1 did not realise what I was doing at the time. The snails 

 were some that I brought from Hastings, and finding that I had more than were 

 needed for my collection, not wishing to kill them unnecessarily, I placed them on 

 the Common." — William Whitwell {Read before the Society, Sept. 9th, 1903). 



Land Shells at High Altitudes.— During a visit to Switzerland this year we 

 went for ten days to Arolla, at the head of the Combe d'ArolIa, in the Canton 

 Valais. The Grand Hotel Kurhaus, where we stayed, is situated in a pine wood, 

 about 350 feet above the river, and an altitude of 6,850 feet above the sea. The 

 pine wood only stretches for a short distance above the hotel, and as usual no 

 shells were found in the wood, but just above the limits of the trees I found under 

 stones Hyalinia radiatula and var. viridescenti-alba, Conulus fulvus, Patula rupes- 

 tris, and P. ruderata, and also Cionella lubrica. These were all found at an 

 altitude of 7,000 feet or over. During our visit we went one day for an excursion 

 to the Lac Bleu de Lucel, and returning by the Cascade des Ignes, and from there 

 up a very rough stone gully in the direction of the Aiguilles Rouges, we found four 

 specimens of Helix arbustoruni var. alpicola fully 7,500 feet or over. I have never 

 before found shells at so high an altitude, and should be glad to know if they have 

 been found higher than this in Europe. — Edward Collier {Read before the 

 Society, Oct. 14, 1903).
