Notes on American Land Shells, No. 4. 

 BY W. G. BINNEY. 



The following Catalogue of American Terrestial Mollusks, is offered in the 

 hope of drawing attention to the subject, and by exciting criticism, to furnish 

 the first step towards an arrangement of the confused synonomy. The list is 

 necessarily incomplete, as but a small portion of the oldest States has been 

 thoroughly searched, and an immense extent of territory remains quite unex- 

 plored. 



The species of the Pacific coast north of Mazatlan, are catalogued separately. 

 The Mexican species will be published in a subsequent paper. 



Reference is made only to authors giving a description or figure of each 

 species.
