 I do not consider this and Vivipara elongata well established 

 American species. If actually found in Florida, they were probably 

 brought from Calcutta, where they both are found. 



Ampullaria urceus, MiiLLER (_A. rugosa, Lam.), is found in Mexico. (Vid. 

 Humboldt & Bonpland, Rec. d'Obs. II, p. 258.) Of its presence in 

 the Mississippi Mr. Say says : The " Ampullaria urceus, L. {rugosa, 

 Lam.) is stated in the books to inhabit the Mississippi River; but 

 I have never been so fortunate as to find it, or to gain any informa- 

 tion relative to it there. Mr. 0. Evans did me the favor to make 

 inquiry at various places on that river, and to exhibit, as somewhat 

 similar, a colored plate of the A. globosa, Swains., to persons from 

 whom information might be expected, and amongst others to some 

 Indians, who in general are known to be accurate observers ; but no 

 one has seen any similar shell in the waters of the Mississippi. I 

 am therefore much inclined to believe that the species is a native 

 of some of the more southern rivers, probably those of Texas. Any 

 information in relation to it, or specimens of the shell, will be very 

 acceptable." (Bixney's ed. p. 195.) See also Haldeman, Mon. p. 11 ;
