Sycon ampullum sensu Jenkin 1908
Jenkin (1908: 443) described a small Sycon specimen under this name from Wasini Island. The name refers to Haeckel’s (1872: 308) Sycandra ampulla, a species from Brazil. The change of the name to ampullum is a mistake, because ampulla is a noun that is not be changed with the gender of the genus name. The data he provided are insufficient to characterize the species. Jenkin did not indicate whether it was stalked, the main feature of Sycon ampulla, so it will remain unnamed until it is redescribed (see also below under additional species from South Africa)
