Dominion Museum, Wellington, New Zealand

Abstract Within its range of variation, the small New Zealand bivalve, Notolepton antipodum (Filhol), includes two Recent and two fossil forms previously described as species. The animal is common around all New Zealand and some details of its ecology and habits are presented. The foot and mantle cavity of the living animal are described and its anatomy briefly outlined. The relationships of Notolepton to Neolepton are discussed. Some details of the movements of the foot, mantle ciliation, and gross anatomy of Pachykellya minima Powell are described and its known distribution is extended from the Subantarctic to North Auckland.
