S. All attempt to exhibit 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 
figures 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.

Note. — I have personally consulted all the works referred to above, 
with the exception of the first American edition of Nicholson’s Ency- 
eyolopedia. This I have not been able to find. I give its date as 1816, 
on the authority of Perussac, 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 publication of the various 
papers, without reference to the time they were read before any Society. 
In the 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 
at the commencement of the various parts, some other date is given.
