ADYERTISEMENT, 



The first part of the Bibliography of American Conchology, 

 prepared for the Smithsonian Institution by Mr. Binuey, was 

 published in March, 1863, and embraced the references to de- 

 scriptions of shells by American authors. The second part of 

 the same work is herewith presented to the public, and relates to 

 species of North American shells referred to by European authors. 



In foreign works binomial authors alone have been quoted, and 

 no species mentioned which is not referred to North America or 

 some specified locality of it. 



The third part (in an advanced stage of preparation) will in- 

 clude the General Index of Authors, the Index of Generic and 

 Specific names, and a History of American Conchology, together 

 with any additional references belonging to Part I and II, that 

 may be met with.
