Extracts from the Minute-Book of the Linnean Society. 765 
March 1. Read the following Letter from Dr. James Lindsay, 
addressed to Roderick Impey Murchison, Esq. F.R.S. 
& L.S. &c., giving an account of the Helix obvoluta of 
Lamarck being found, apparently indigenous, in Hamp- 
shire. 
* Sir,—Last May, when searching for land shells, 
I was surprised to meet with the Helix obvoluta, 
hitherto considered a foreign species, and, I believe, 
never before noticed in Great Britain. 
** I discovered it, along with other Helices, such as the 
Helix nitida and rufescens, 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 indi- 
viduals. 
** Lamarck describes the French shell as having the 
margin of the lip white; but in the Hampshire speci- 
mens, when fresh, that part is tinged with red. La- 
marck takes no notice of the smooth, tooth-like pro- 
cesses 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 ex- 
ternally, and in every other respect answering to the 
Lamarckian description. 
* Should you consider these observations worthy 
the notice of the Linnean Society, I shall feel gratified 
in your presenting them. 
** I am, your most obedient Servant, 
T
