" Monograph ie des Coquilles Bivalves Fluviatiles de la Riviere Ohio, 

 contenant douze Genres et soixante huit Especes." In Annates Generates 

 des Sc. Physiques, Tome iii. Bruxelles, Sept. 1820. 



C. A. Poulson, of Philadelphia, in 1832, translated this last pa- 

 per of Kafinesque's and published it in a small volume entitled : 



" Monograph of the bivalve fluviatile Shells of the River Ohio." 



D. H. Barnes was the next American writer on Shells. He 

 published in this Journal ([1], vi, No. 1, 1823,) an important 

 paper " On the genera Unio and Alasmodonta, with introductory 

 remarks." This article, which contains descriptions of several 

 supposed new species, bears evidence of considerable knowledge 

 of the Naiades. Some of his species were, however, anticipated 

 by Lamarck, who became early acquainted with a number of 

 our Uniones. 



In vol. xiii, of this Journal, Mr. Barnes made a reclamation 

 of his species of Naiades. He also contributed a paper describ- 

 ing five new species of Chiton in vol. vii, No. 1. 1824. Mr. 

 Barnes was one of the earliest contributors to the " Annals" of 

 the New York Lyceum of Natural History, of which Society he 

 was an efficient member. He published three papers in the first 

 and second volumes of the Annals, 1824-28. He was accident- 

 ally killed, Oct. 27, 1828. 



Dr. Jacob G-reen" (deceased) was one of the earliest workers 

 in this department of Natural Science. The following papers by 

 Dr. Green are in the Contributions to the Maclurian Lyceum : 



1. "Description of Helix Pennsylvanicus." Note to a Memoir on Sal- 

 amander, p. 8. Read Oct. 23, 1826. 



2. " Some Remarks on the Unios of the United States." Read April 

 23, 1827. 



3. " Description of two new species of Achatina from the Sandwich 

 Islands." Read May 14, 1827. 



4. "Remarks on Achatina Stewartii." Read Sept. 21, 1828. 



His papers in the Transactions of the Albany Institute con- 

 sist of — 



1. "Monograph of the Cones of North America, including three new 

 species." 



2. "The Dolia of the United States," and 



3. "Notes on American Shells figured in the Supplement to the Index 

 Testaceologicus." All read June 7, 1830. 



He also contributed papers at various times to Doughty 's Cabi- 

 net of Natural History. Vols, i, ii, iii. Philadelphia, 1830-33. 



Dr. S. P. Hildreth, of Marietta, Ohio, a well known contrib- 

 utor in other departments to this Journal, published in the first 

 series, vol. xiv, 1828, an interesting paper on the shells inhabit- 

 ing the vicinity of that town.
