Inle Lake in central Myanmar is one of the hotspots of freshwater biodiversity in Southeast Asia. A small malacological collection from the lake made by Thomas Nelson Annandale and discovered at the Kyoto University Museum, Japan was examined here. In the collection comprised of thirty specimens, nine species in seven families were identified. The collection also included four species and one subspecies which were newly described by Annandale. Two subspecies, Hydrobioides nassa lacustris Annandale, 1918 and H. n. rivulicola Annandale, 1918, were identified in a single lot. The correspondence of the shell morphology of Lamellidens ferrugineus (Annandale, 1918) between the present study and the original description indicates that the specimen is a paratype of the species. The rediscovered collection provides us with insights into the species definition of Annandale and the molluscan diversity of the lake prior to recent environmental changes.
