Abstract
The chromosomes of two similar lymnaeid snail species, Austropeplea ollula from Korea and "Lymnaea"sp. introduced to Australia, were karyologically investigated by using an air-dry method. The diploid chromosome number found in A. ollula was 32, and that of "Lymnaea" sp. was 30. The mitotic chromosome complements of A. ollula were 5 metacentric, 9 submetacentric, and 2 subtelocentric pairs. "Lymnaea" sp. had 5 metacentric, 8 submetacentric, and 2 subtelocentric pairs. Austropeplea ollula is distinguishable from "Lymnaea" sp. by their chromosome numbers.
