Mitcham, sinistral specimen. Finder unknown. 



x'Vs possibly very few have had the opportunity of seeing Dr. James 

 Lindsay's article on his discovery of H. obvoluta at Ditcham Wood, 

 nearly a century ago, I append a transcript of the paper, kindly sup- 

 plied me by Mr. J. W. Jackson, from Transactions Linnean Society, 

 xvi, 765 :— 



March ist, iSji . Read the following letter from Dr. James Lindsay, 

 addressed to Roderick Impey Murchison, Esq., F. R.S., etc., giving an 

 account of the Helix obvoluta Lam. being found apparently indigenous in 

 Hampshire. 



"Sir,— Last May, when searching for land shells, I was surprised to 

 meet with the Helix obvobita, hitherto considered a foreign species, and, 

 I believe, never before noticed in Great Britain. 



" I discovered it, aTong with other Helices, such as Helix nitida and 

 7-ufescens, amongst the moss near the roots of trees in Ditcham Wood, near 

 Buriton, Hants. This shell is found for a considerable distance along 

 the chalk escarpment of the South Downs, facing to the north ; and although 

 more rare than the other species above mentioned, I have collected above 

 twenty individuals. 



" Lamarck describes the French shell as having the margin of the lip 

 white ; but in the Hampshire specimens, when fresh, that part is tinged with 

 red. Lamarck takes no notice of the smooth tooth-like processes on the inner- 

 side of the lip, which in this species are always present. The aperture is 

 triangular ; the mouth a little reflected, forming a distinct sinus internally, 

 and in every other respect answering to the Lamarckian description. 



"Should you consider these observations worthy of the notice of the 

 Linnean Society, I shall feel gratified in your presenting them. 

 I am, your most obedient servant, 



James Linjjsay.
