A LIST OF LAND AND FRESHWATER SHELLS 

 COLLECTED IN THE NEIGHBOURHOOD OF 

 WAKEFIELD. 



By JOSEPH HEBDEN.

 and for much valuable information, I am indebted to my friends 

 Messrs. Wm. Lund and G. Taylor, the former of whom was for 

 many years a most assiduous and successful conchologist.

 desirability of restricting the area of the district.
