LAND AND FRESH-WATER SHELLS FROM EASTERN CANADA. 



BY E. G. VANATTA. 



The following species of shells were taken by Mr. Bayard Long- 

 while collecting plants in the Magdalen Islands and Prince Edward 

 Island in the Gulf of St. Lawrence. The snail fauna seems to be 

 the usual northern type with the addition of the European Helix 

 hortensis Miill., Hygromia hispida L., and a new Succinea related to 

 western American forms. 

 Succinea bayardi n. sp. Figs. 1, 2, 3. 



Shell rather small, oval, globose, thin, polished, apex red, obtuse, 

 body whorl translucent amber colored, with a few growth striae, 

 whorls about 2\, convex, rapidly increasing, suture impressed. 

 Aperture more than half the altitude, very broadly oval, parietal 



callous, thin, outer and basal lips thin and evenly arched, columella 

 very narrow below, expanded above into a translucent white fold. 



Alt. 5.7, diam. 4.3, aperture alt. 3.8, diam. 2.8 mm. 



Locality. — Indian River, Kensington, Prince Edward Island. Col- 

 lected on August 29, 1912. The types are No. 106,651 in the col- 

 lection of the Academy of Natural Sciences of Philadelphia. 



This shell is very closely related to Succinea oregonensis Lea, but 

 has a lower and more obtuse spire and is a smaller species. It 

 differs from Succinea chrysis West by lacking the opaque streaks, is 

 not green or reddish, and is smaller. I take pleasure in naming this 

 shell after Mr. Bayard Long, the botanist, who collected it. 



Helix hortensis Miill. 



Nineteen specimens were collected at Basin Island near Coffin Id., 

 Magdalen Islands, of which ten were the form 12345, two (12)345, 

 one (123)(45), two (123)45, one 1(2345), one (12345), one 10305, 

 and one 00000; at Grindstone, Grindstone Island, M. I., nine speci-
