Extracts from the Minute-Book of the Linnean Society. 7G5 



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 HclLv obvoluta of 

 Lamarck being found, apparently indigenous,in Hamp- 

 shire. 



" Sir, — Last Maj?-, 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. 



"1 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-iike 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, 1 shall feel gratified 

 in your presenting them. 



" I am, your most obedient Servant, 



" lOth November, 1830, " JaMES LiNDSAY.
