Mr. Lea's cabinet of Unionidoc is unequalled in the world. It 

 includes many thousands of carefully selected specimens from 

 all parts of the world, exhibiting all the variations from specific 

 types so common in this family. 



Dr. Gould possesses a valuable collection, containing many 

 types of species. 



The most valuable cabinet of West India terrestrial shells is 

 that of Mr. A. D. Brown, of Princeton, N. J., formerly the 

 property of Thomas Bland. Mr. Bland's extensive correspond- 

 ence in the West Indies, and especially with Prof. Poey, Dr. 

 Grundlach, M. Salle, K. J. Shuttleworth, &c., his own collections 

 in St. Thomas, Jamaica and Bermuda, and his intimate relations 

 with the late Prof. C. B. Adams, gave him extraordinary advan- 

 tages and opportunities. Mr. Brown also has a large number of 

 species of terrestrial mollusca from other countries — the whole 

 amounting to three thousand species. 



John G. Anthony of Cincinnati has a fine collection of Ameri- 

 can freshwater shells, principally Melanians, collected by himself. 



The finest cabinet of operculated land shells is that of Mr. J. 

 H. Kedfield, late of New York, now of Philadelphia; he has 

 also a large collection of Marginellid.se, which he has made his 

 especial study. 



The collections of Temple Prime and Wm. Stimpson are ex- 

 ceedingly rich in their respective specialities, the Cyclades, and 

 American marine mollusca. 



Dr. E. Ravenel, of Charleston, S. C, an experienced conchol- 

 ogist, and one who has done much to further the study among 

 us, possesses a valuable cabinet, rich in marine and other spe- 

 cies, determined by Thomas Say. 



There are numerous private collections in this country contain- 

 ing from one to five thousand species; among these may be 

 mentioned those of Hon. E. Cowan of Pennsylvania, U. S. Sen- 

 ator; Theodore Gill, containing three thousand species ; Dr. E. 

 K. Foreman of Washington, D. C, thirty-five hundred species; 

 and R. L. Stewart of New York. 



The cabinet of Geo. W. Tryon, Jr., of Philadelphia, embraces 

 over four thousand species, and many varieties. It includes a 

 large number of American Unionidse and Melaniada^, supplied 

 by Isaac Lea, Mr. Binney, and numerous others : a good suite of 

 American terrestrial shells from Mr. Binney, many West Indian 

 land shells, including a number of Adams' Jamaica species, and 

 of Pfeiffer's (author's examples), and a fine Cuban suite from 

 Prof. Poey; a splendid collection of Achatinelhe from Dr. New- 

 comb, a series of European terrestrial shells (several hundred
