are densely and completely annulated with more than 45 rings, but this annulation progressively vanishes after the first branch, even though it continues for four millimetres more. The first branch is also densely ringed until it passes a gonophore-bearing pedicel, which, in turn, is completely annulated. The rest of the stem and branches are smooth in general, although sometimes there are a few rings at the origin of branches.

high, but unfortunately her material was too poorly preserved to provide information on the cnidome. Millard’s material had both male and female gonophores, the former being one- to two-chambered, which would agree with our material. However, she indicated that the tentacles of the fertile polyps appear to be persistent, whereas in the present material male gonophores are on completely reduced polyps. In addition, in Millard’s material, groups of annulations are present at branch origins and rarely at other points.
