[There is no paging. I am indebted to the kindness of Mr. S. Hanley 

 for the date and references to this edition. I have never been able to 

 obtain access to a copy of it, though I have searched for it in all the prin- 

 cipal libraries of Boston, New York, and Philadelphia. The second and 

 third editions are common. The original manuscript is preserved in the 

 library of the Philadelphia Academy of Natural Sciences. This paper was 

 also distributed separately with a distinct title-page, " Descriptions of Land 

 and Fresh- water Shells of the United States."— W. G. B.]
