XYIII. Trans- Atlantic Peovince. 



The Atlantic coast of the United States was supposed by Prof. 

 E. Forbes to consist of two provinces : (1) the Virginian, from C. 

 Cod to C. Hatteras, and (2) the Carolinian, extending to Florida; 

 but no data were supplied for sucli a division. The total num- 

 ber of mollusca is only 230, and 60 of these range farther north, 

 1 5 being moreover common to Europe. These two regions are 

 sometimes treated of together as the Pennsylvanian province. 



Dr. Gould describes 110 shells from the coast of Massachusetts 

 south of Cape Cod, of which 50 are not found to the northward, 

 but form the commencement of the proper American type. The 

 shells of New York and the southern Atlantic States are de- 

 scribed by De Kay, in the State Natural History of New York ; 

 this list supplies 120 additional species, of which at least a few 

 are stragglers from the Caribbean province; e.g. Chama arcinellaj 

 Jphigenia Icevigata, Capsula deflorata*
