OCCURRENCE OF THE SWAMP LYMNAEA, Lymnaea stagnalis (GASTROPODA: PULMONATA) IN ATLANTIC CANADA

Abstract

The occurrence of the swamp lymnaea, Lymnaea stagnalis (linnaeus 1758). a large,
distinctive, pulmonate snail, has been documented in Atlantic Canada for the first time. It is unclear if the populations reported here are relictual, or whether L stagnalis has been introduced into Atlantic Canada.

On a signata pour la premiere fois, dans Ie Canada atlantique, I?I pre~ ence de la
grande Iymnee des etangs, Lymnaea stagnalis (linne, 1758). un gros escargot putmane caracteristique. On ne sait pas si les populations signatees sont relictuelles ou si L. stagnalis a ete introduit au Canada atlantique.
