Murex Vindobonensis Hoernes — Mayer 1864: 71.

Discussion. As with the species above, this determination was based on two small fragments from Feteirinhas (= Ponta das Salinas) and said to belong to the Murex erinaceus group. Today, this species is placed in the genus Ocenebra Gray, 1847 . Two sub-species are recognized O. vindobonensis vindobonensis (Ĥrnes, 1853), present in the Lower and Middle Miocene Paratethys and eastern Proto-Mediterranean, and O. vindobonensis ligeriana (Tournouër, 1875) from the Atlantic middle Miocene of the Loire Basin, France. This species complex is typically Miocene (Landau et al., 2006c), and we prefer to exclude this record until further verified.
