30 History of Conchology in the United States. 



compelled the omission of much that would be of interest to the 

 reader, who is referred, for a more complete list of Authors and 

 their Papers, together with accurate dates of publication, to the 

 work at the head of this article, which has furnished us with 

 most of the material for the foregoing pages. 



It will be seen that our several scientific Journals have con- 

 tained a very large number of papers by our best authors — thus, 

 the publications of the Boston Society have those of Adams, A. 

 Binney, Couthuoy, Gould, Prime, &c. The New York Annals 

 those of Adams, Anthony, Bland, Newcomb, Prime and lied- 

 field. The Journal and Proceedings of the Philadelphia Acad- 

 emy have the valuable papers of Say, Conrad, Anthony, Lea, 

 W. G. Binney, Leidy, Prime, Stimpson, &c. The Philosophical 

 Transactions contain many of Lea's extensive articles ; while 

 papers by many of these authors have also appeared in this 

 Journal. 



There are many fine public and private collections of shells 

 in the United States. That of the Academy of Natural Sciences 

 embraces about eleven thousand species. In the arrangement 

 of the Academy's Cabinet, Pfeiffer's system is followed for the 

 terrestrial species, while with the fluviatile and marine shells, 

 the Lamarckian system is generally adhered to, with the intro- 

 duction, however, of many of the more recent genera. 



The splendid collection belonging to Amherst College is a 

 noble monument of the unflagging assiduity and scientific attain- 

 ments of the late Prof. C. B. Adams, who formed it. It em- 

 braces types of all his species and full suites of the shells of the 

 various West India islands, and of Panama. It is esteemed by 

 competent judges the most valuable collection for study in the 

 United States. 



The Boston Society of Natural History, the New York Ly- 

 ceum, the Mercantile Library Co. of Cincinnati, Union College, 

 Schenectady, N. Y. (formerly collection of C. M. Wheatley, of 

 Phcenixville, Pa.), the Agassiz Museum and the Smithsonian In- 

 stitution, each possess valuable collections. 



The largest private collection in this country is that of Dr. John 

 Clarkson Jay, of Mamaroneck, N. Y., numbering 13,4G0 species 

 and numerous varieties. They are arranged according to the 

 Lamarckian system. We have already alluded (p. 169) to his 

 extensive and useful catalogues of his collection. 



Wm. S. Haines of New York possesses twelve thousand spe- 

 cies of shells, including many rare and unique ones. 



Mr. Binney has a small but exceedingly valuable collection of 

 the terrestrial shells of the United States, including many types 

 of species, and also geographical series. The same may be said 

 of the cabinet of Mr. Bland of New York.
