a beauty, rich dark red 00(345), the broad black band being very 

 distinct. 



From Bunbeg we went on to Burton Port, the end of the railway, 

 and worked Cruit Island the first day. Cruit Island is a long island 

 running north, and at low tide can be reached on foot near the 

 southern end, but we drove some considerable distance, and went 

 by boat, and were landed nearer the northern end. Here we found 

 H. nemoralis at once on the grass, as at Bunbeg, but more variable 

 in colour, as we found several rubella 00000. Type and var. albo- 

 labiata were both again very plentiful, l)ut some of the shells were 

 rather smaller and higher in the spire, ^^'e also found here a few 

 var. a'triiiozonata, but not many. 



The weather turned out so ver\- wet that we could not go out to 

 Aran Island, which is the largest island off this part of the coast ; 

 but as it is nearly all bog-land, we should most likely not ha\e been 

 very successful. So we took train back to Londonderry, where we 

 stayed the night, and next morning, under the guidance of Mr. J. N. 

 jNIilne, of Belfast, who had been with us all the time, we went on to 

 Magilligan in County Derry, where there is a long stretch of sand- 

 dunes. Here we were fortunate enough to come across a colony, 

 restricted so tar as we could make out to a very small area, of a new 

 variety which I think is worthy of a name, as although I have col- 

 lected for a very long time, I have never found anything like it before. 



It is distinctly olive-coloured, going rather darker near the mouth, 

 and the mouth also is the same colour. It is of various band for- 

 mulas, like both roseozonafa and citiinozonata, and I prefer to call 

 it olivaceozonata. 



To sum up the result, there was nearly a total absence of var. 

 rubella, none of the common band formula 00300, and a very large 

 quantity of var. albplabiata. Can anybody explain the reason of this? 



Land and Freshwater Mollusca from Tooting, London, S.W. — I have 



no doubt that it will surprise niuny conchologists — and paiticularl)- Londoners — to 

 be told that Tooling is an excellent habitat for land and freshwater mollusca ; and 

 yet this is perfectly true, for in a field between Tooting and Merton and just out- 

 side the L.C.C. l)oundary I have taken fifty species. It was merely chance that 

 led me to this spot, as, having a free afternoon on Nov. 3rd, 1906, I set out to look 

 for Merton Abiiey — a building which, I believe, now no longer exists, although 

 indicated on the Ordnance Maps. Although the abbey is gone, the name still 

 remains, as there is a station on the L. B. and S.C. Railway — Wimbledon line — 

 called Merton Abbey, and it was while I was prowling round this that I noticed 

 a rather tempting '" watercress bed " on the opposite or southern side of the rail-
