Abstract
LAST year, when considering evolutionary trends in capitate hydroids and medusæ1, I was astonished by the remarkable similarity between some of these forms (Euphysa hydroids and Sarsia medusæ) and the hydroid and medusa of Moerisia lyonsi Boulenger2. The latter and related species of the family Moerisiidae have for some time been placed in the Limno-medusae3, an order which includes such diverse forms as Proboscidactyla (Lar, the posturing polyp of Gosse) and Craspedacusta (the freshwater medusa).
