BIBLIOGRAPHY. A. — GENERAL WORKS. 



This list includes general faunal lists and general descriptive works in 

 North American Oonchology. In all of them are to be found matters of 

 more or less interest to the student of Indiana mollusca. 

 Poulson, C A. A Monograph of the Fluvlatile Bivalve Shells of the 

 river Ohio, containing twelve genera and sixty- eight species. 1832. 

 A trauslation of Rafmesque's older work, which see. 

 Say, Thomas, F. M. L. S. American Conchology, or Descriptions of 

 the Shells of North America. New Harmony, Indiana. 18o0-1834. 

 Illustrated by colored figures from original drawings executed from nature. 

 Conrad, T. A. Monograph of the Family Unionidse. 183-5-1839. 

 Lea, Isaac. LL. D. Observations on the Genus Unio. 13 volumes, 4to. 

 1830-1874. 



These volumes were originally published as portions of the Transactions of the Amer- 

 ican Philosophical Society and of the Journal of the Philadelphia Academy of 

 Sciences. They were afterwards collated and issued separately under the above 

 title. 



A Synopsis of the Family Unionida?. Four editions. 1830-1870. 



This work has almost a complete bibliography of the Unionidse, particularly the 

 American forms. There are also tables of geographical distribution, but these are 

 little more than a mere list of the original localities for the American species. 

 Catalogue of the Unics, Alasmodontas and Anodontas of the 

 Ohio river and ita northern tributaries, adopted by the Western 

 Academy of Natural Sciences of Cincinnati. January, 1849, pp. 19. 

 There are listed in this remarkable little brochure fifty-six species of Unio, six of 

 Margariiuna, and five of Anodonta. The catalogue is remarkable as being the first 

 open expression hostile to the claims of both Say and Raflnesque. It marks the 

 beginning of along and bitter controversy, from the eflfects of which American 

 malacology has not yet fully recovered.
