 Mr. Lea, President in the Chair. 



Thirty-eight members present. 



The report of the Biological Department was presented. 



The following resolution, presented by Dr. Leidy on behalf of the

Resolved, That the Publication Committee and the Committee on

 Proceedings of the Academy as can be spared, for the suite of Palaeozoic 

 fossils, which have been offered by Mr. J. N. H. Barris. 



The following papers were, on the report of the Committees to whom 

 they had been referred, ordered to be published in the Proceedings. 



Notes on American Land Shells. No. 6, 

 BY W. G. BINNEY. 



The Catalogue of the Terrestrial Mollusks of North America, commenced in 

 the Proceedings of the Academy for November, 1858, and continued in the 

 number for July, 1859, is here completed. The list is believed to contain all 

 the species described as inhabiting Mexico. I have followed the systematic 

 arrangement of Drs. Gray and Pfeiffer in grouping the genera, and the de- 

 cisions of the latter in regard to the synonymy. 



Many Central American species will undoubtedly be added to the list when 

 their geographical range is better known. The species of the Pacific coast, 

 included in the first section of the Catalogue, are omitted here, viz.: Nos. 3, 

 7, 8, 11, 23, 25, 35, 37, 39, 40, 41, 42, 43, 45, 46, 47. 



For additional species, changes of nomenclature, &c, &c, of the section of 

 the United States, see Boston Journal of Natural History, vol. vii., and the 

 Remarks on North American Helicidse by Mr. T. Bland, in Annals of New 

 York Lyceum of Natural History, vol. vi.
