The Smithsonian Institution has endeavored to procure the 

 compilation of a series of Manuals of North American Concho- 

 logy, of which several are now in press, and others in an advanced 

 stage of preparation. The present work, which has been com- 

 piled by Mr. Binney, serves as a companion to the above men- 

 tioned series, and presents at one view the complete bibliography 

 of the references in the other volumes. 



Of the two parts into which the plan of Mr. Binney divides the 

 work, Part I, with its three sections, is herewith presented. Tart II 

 is in press, and will embrace, in addition, a full index of authors, 

 with a list of the publications of each, and a complete alphabetical 

 index of all the names and synonyms, both generic and specific, 

 referred to. 



In order to render the work more perfect, a copy will be sent, 

 as far as possible, to each living author mentioned, who is par- 

 ticularly requested to examine carefully and critically the account 

 of his own writings, and to communicate to the Institution any 

 errors or omissions, or any suggestions for improvement, to be 

 incorporated into au appendix to Part II.
