Ampui<IvAria cai^iginosa Rve. 



Ampullaria caliginosa Reeve, Con. Icon., Ampullaria, 1856, pi. XXV, fig 



118. 

 Type locality: Unknown. Not listed by Sowerby in his recent catalogue 



(119, pp. 345-362). 

 Ivisted from several localities in Florida by Dall and Simpson. 



AmpulIvARIA miamiEnsis Pilsbry. 



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

 Type locality : Miami, Dade Co., Fla. 



AmpulIvAria pai^udosa Say. 



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

 was preoccupied by Lamarck. 



AmpulIvAria piNiii Dall. 



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

 Type locality: Homosassa River, Fla. 



AmpuIvIvAria rotundata Say. 



Sowerby has recently (119, P- 357) referred this species with doubt 

 to paludosa, overlooking Say's statement that the operculum was 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. globosa Sw." 



Family VIVIPARIDJi. 



Genus VIVIPARUS Montfort, 1810. 



ViVIPARUS CONTECTUS (Millet). 



This European species has become fully acclimatized at Washington, 

 D. C, and at Philadelphia, Pa. (Bailey, 2, p. 60). 



A^iviPARUS coNTJvCTOiDKS W. G. Binney. 



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

 lineata Kuster non Val. (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)^.
