Introduction
The Ulmaridae contains four subfamilies, the Aureliinae, Sthenoniinae, Stygiomedusinae, and Ulmarinae; only the Aureliinae is represented in Australian waters. Von Lendenfeld (1884d) described Aurelia coerulea from Sydney, and it appears to be distinct from Aurelia species overseas. However, with new information about species boundaries in Aurelia, it seems highly likely that other species of the genus are present in Australian waters, remaining to be discovered.
Aurelia is one of the commonest jellyfishes on earth, and indeed, in Australian waters as well. It is easily identified, having a flat body with thousands of short, fine tentacles along its scalloped margin, and four conspicuous gastro-gonadal rings near the centre of the body.
Diagnosis
