Extract

During the last four years collections of plankton from deep water have been made regularly on the cruises of R.V. ‘Sarsia’. The opportunity has been taken to study the biology of the scyphomedusa Atolla wyvillei. It was hoped that with material collected from the same area at different times of the year it might be possible to gain some information on the growth and length of life of this medusa. The collections have been supplemented by a number of specimens taken on recent cruises of R.R.S. ‘Discovery II’, and a total of nearly 300 medusae have been examined. The collections were made with the 2 m stramin ring trawl and the Isaacs-Kidd pelagic trawl mostly from the Bay of Biscay.
