(Quoy and Gaimard, 1827)
Nectosome reduced bearing a maximum of 5 nectophores. The nectophores are boot-shaped, with the nectosac occupying most of the foot, and a long, thick pedicular canal running from its apex up through the heel. The flattened base has two facets separated by a central protuberance. The dorsal radial canal is straight, while the ventral one makes several curves. The lateral canals are looped. The large, gelatinous bracts bear a proximal keel for attachment. The dorsal surface of the mature bracts bears several rows of prominent papillae. A very distinctive species. Only the most distorted nectophores in any way resemble those illustrated by Totton (1954).
