 H. All attempt to exMbit a Synonomy of the Western North American 

 species of the genera Unio and Alasmodonta, given with part 6 

 of American Conchology. April, 1334. 

 Some of the descriptions contained in the New Harmony Dissemina- 

 tor, not repeated in the American Conchology, were reprinted in 

 pamphlet form by Mrs. Say, New Harmony, Indiana, 1840. 



The American Conchology was intended to contain descriptions and 

 Jigures of all the known species of American Mollusca. The noble under- 

 taking was arrested, by the death of the author, at part 6. The sev- 

 enth number was sufficiently advanced to allow its completion and pub- 

 lication by Mr. T. A. Conrad. A French translation of parts 1 to 5 has 

 been published by M. Chern in his Bibliotheque Conchyliologique, vol. 

 ill. 



NoTK. — I have iJersonally consulted all the works referred to above, 

 vrith the exception of the first American edition of Nicholson's Ency- 

 nyolopedia. This I have not been able to find. [ give its date as 1816, 

 >.n the authority of Ferussac, Mag. de Zool. 1835, cl. v. 59, 60, p. 11. I 

 believe its species to be the same as in the second edition. The dates 

 in the text and index are invariably of the puhlication of the various 

 papers, without reference to the time they were read ])efore any Society. 

 1 u tlie Journal of the Academy, I have been forced to adopt the date 

 )f the general title page of each volume, unless with the signatures, or 

 ■».t the conxmencement of the various parts, some other date is given.
