Recent collections of freshwater mussels (Bivalvia, Margaritaferidae, and Unionoidae) in Kansas included two species previously not documented from the state: Cumberlandia monodonta (Say, 1829), spectaclecase, and Cyclonaias tuberculata (Rafinesque, 1820), purple wartyback. The collections also have provided distributional revisions for five other mussel species.
