Ampullaria miamiensis Pilsbry, Pr. A. N. S. P., 1899, p. 365.

Ampullaria paludosa Say. 



This name must be nsed for Say's species as his first name depressa 

 was preoccupied by Lamarck. 



Ampullaria pinli Dall. 



Ampullaria pinei Dall, Naut., XII, 1898. p. 75. 

 Type locality : Homosassa River, Fla. 



Ampullaria rotuxdata Say. 



Sowerby has recently (119, p. 357) referred this species with doubt 

 to palndosa, overlooking Say's statement that the operculum w'as calcareous 

 and Binney's figure in his edition of Say, pi. 75. It is no doubt an Old 

 World species as suggested by Binney. In a recent letter, Mr. Sowerby 

 says that he has "not the slightest doubt that it is a small specimen of the 

 Indian A. cjlohosa Sw\" 



Family VIVIPARID^. 



Genus VIVIPARUS Alontfort, 1810.

Tryon's contention (132, p. 17) that this species should be known as V. 

 lineata Kuster non Yr\. (Con. Cab., Paludina, 1852, p. 10, pi. 2, figs. 6-9) 

 is not well founded. Lineata is preoccupied and linearis (Ibid. p. 19) is 

 "of course'" a misprint for lineata as stated by Tryon (131, p. 197) and 

 Binney (13, P- 295). 



This species has been introduced and fully acclimated in Fairmont Park, 

 Philadelphia, Pa. (Vanatta, 139, p. 84), and in the Public Garden in Bos- 

 ton, Mass. (Johnson, 62, p. 72).
