68 Peacock : Helix iieinoralis L. in North-west Lines. 



Conisborough. Two of these we are able to reproduce by 

 permission. Mr. Gould strongly urges the importance of pre- 

 serving relics of this character. ' We all know, only too well, 

 how many interesting relics of Celtic, Roman, Saxon, and later 



periods have been ruthlessly swept away in the course of agri- 

 cultural and other operations ; landowners, farmers, builders, 

 railway companies, and even the War Office have aided in the 

 work.' It is pleasing to know that, at any rate, the pre-historic 

 fortress on Wincobank Hill is to be preserved, having been pre- 

 sented to the City of Sheffield by the Duke of Norfolk. 



Helix nemoralis L. in North-west Lincolnshire. — On p. 36 



of 'The Naturalist,' 1905, I asked if anyone had ever found 

 Helix 7iemoralis, 12300, in Britain, for it is not uncommon in 

 Ireland. A few days before I wrote I had gathered some 

 hundreds of shells from the freshwater alluvium of Kettleby 

 Beck in this parish. They were unsorted when I wrote. 

 Amongst them I find the variety 7ninor (Moq.) + conica (Pascal) 

 + (123)00. It is a slightly weathered and 'dead' specimen, 

 which the Thrush had carried to the anvil stone, but not 

 attempted to break. In my thirty years' experience this shell is 

 unique. — E. Adrian Woodruffe Peacock, Cadney, Brigg, loth
