Three specimens of a rare anthomedusa collected by the R.V. “Sarsia” west of the English Channel, are described and compared with Paragotoea bathybia Kramp, 1942 and have been identified with it.

With age, the number of tentacles increases from one to four and a quadrate stomach with four stomach pouches is developed as the medusa matures.

A quadrate stomach is regarded as significant in determining the affinities of Paragotoea and a new anthomedusan family Paragotoeidae is created for it.

Pending the discovery of more specimens of the Japanese form, Gotoea Uchida 1927, is recognized as distinct from Paragotoea and retained in the family Tubulariidae.
