title: The life cycle of corymorpha (=euphysora) bigelowi (maas, 1905) and its significance in the systematics of corymorphid hydromedusae.
abstract: 1. Five individuals of the corymorphid jellyfish, Euphysora bigelowi Maas, were collected in 1973 in Monterey Bay, California, for a range extension of more than 8,000 km across the northeastern Pacific Ocean. 2. Larvae released by these medusae were cultured and the resulting polyps, the first known from this medusa genus, are described. 3. The polyps are a Corymorpha, but share some minor characteristics with polyps of the corymorphid genus Euphysa. 4. The polyp and medusa are assigned the name Corymorpha bigelowi (Maas); the systematic implications of this revision are discussed.
