Abstract
In July and August 1929 the writer's father, Mr D. K. Kevan, found large numbers of a species of Lymnœa, cleaned out of a warm engine-pond in a timber yard in Leith. These snails showed much variation in the form of the shell, and this made identification difficult.In July and August 1940 the writer revisited the locality, collected a considerable number of living snails from the pond in question, and eventually established that they belonged to the common North American species, Lymnœa (Stagnicola) catascopium, Say.
