Wood, Thomson, lia Hontan., &c. — In the descrip- 

 tions of New England, Virginia, and other parts of North 

 America, published in the seventeenth and eighteenth centu- 

 ries, occur many notices of the Shells of the country. Of no 

 scientific value, they are still interesting to the Conchologist. 

 As samples, I quote the following: — 



Anonymous. — A perfect description of Virginia; being a full and true 

 Relation of the present State of the Plantation, their Health, Peace, and 

 Plenty ; the number of people, with their abundance of Cattell, Fowl, 

 Fish, &c. &c. &c. London: Printed for Richard Wodenoth, at the
