Changes in the Molluscan Fauna of White Lake, Lanark and Renfrew Counties, Ontario, After Thirty Years

---

Abstract

In July, 1965, on a prospecting trip for shell marl with one of my graduate students, I returned to White Lake and spent a few hours collecting Mollusca and marl from the bottom of the lake. The marl fauna will be reported upon later. The object of this paper is to point out an addition to the molluscan fauna of White Lake and an apparent change in the abundance of other species. The most remarkable feature of White Lake this summer (1965) is the extraordinary abundance of a viviparid snail, tentatively identified as the European Viviparus viviparus Linn, which seems to have taken over most of the lake. Further details on it's occurrence are given below.
