Extract

The hydroid of the medusa Modeeria rotunda (formerly Tiaranna rotunda) has been found to be the thecate species Stegopoma fastigiatum. The medusa has been obtained from the hydroid and reared to maturity. The stages of development of the medusa are described and figured, and its occurrence and habits are discussed. The affinities of the medusa are considered: it is shown to belong, together with the the genus Chromatonema, to the family Laodiceidae.
