Abstract
Abstract A sudden infestation of medusae, identified as Craspedacusta sowerbyi Lankester, occurred in Lake Maraetai, North Island, New Zealand, during the last week of January 1970. Previous records of immature medusae in North Island lakes and of hydroilds in a Dunedin aquarium probably refer to the same species. High water temperatures favoured development of the medusae, but their effect on the ecology of the lake was probably negligible.
