History of Conchology in the United States. 25 



Prof. Haldeman has published in Chenu's "Illustrations Con- 

 chyliogiques," a "Monographic du genre Leptoxis, Rafinesque; 

 (Anculosa, Say.)" Folio, Paris, 1847, with beautiful plates. He 

 has also contributed several papers to the scientific Journals, 

 among which is an "Enumeration of the Recent Fresh-water 

 Mollusca which are common to North America and Europe, with 

 observations on species and their distribution," in the Boston 

 Journal, iv, p. 468, 1844. This paper, together with the com- 

 parisons instituted by Prof. Adams with our marine species, and 

 by Dr. Binney in the terrestrial shells, has furnished much valu- 

 able information in regard to the geographical range of species 

 over parts of two continents. 



Henry C. Lea, son of Isaac Lea, has evinced considerable tal- 

 ent in the sciences of Conchology and Geology. He has a short 

 paper in the first series of this Journal ; and a more extensive 

 one in the Boston Journal, entitled " Descriptions of some new 

 species of marine shells inhabiting the coast of the United 

 States." He also assisted his father in the determination and 

 description of the exotic Melanians in the collection of Mr. 

 Cuming. 



Charles M. Wheatley, M.A., of Phcenixville, Pa., who has 

 formed an excellent private collection of shells (now the property 

 of Union College), published, in 1842, the first general " Cata- 

 logue of the Shells of the United States, with their localities." 



New species of shells from Maine are described by Dr. J. W. 

 Mighels, in the Bost. Journal, iv, p. 37, January 1842. 



These Catalogues are very useful in stimulating research, and 

 also afford much information regarding the geographical distri- 

 bution of species.
