The Commission has declined to fix the neotype of Helix papillaris Müller, 1774 as neotype for Turbo bidens Linnaeus, 1758. As a result, Turbo bidens is not a senior synonym of Helix papillaris (currently Papillifera papillaris). Instead the neotype for Turbo bidens designated by Kadolsky (2009) is allowed to stand.
