Papillifera papillaris, also known as Papillifera bidens, is a species of small, air-breathing land snail with a clausilium, a terrestrial pulmonate gastropod mollusk in the family Clausiliidae, the door snails. This is a Mediterranean species.
In Britain this species is now sometimes called the "Cliveden snail", as in 2004 a very small colony was found to have been living on the estate at Cliveden House, a large stately home in Buckinghamshire, England. Individuals of the species had been living on an Italian balustrade which was imported to Britain in the late 19th century, and have survived at the estate for over a century before they were discovered there. Other introduced populations of P. papillaris can be found across South East England.
Based on some recent research, it appears that there is a somewhat complicated nomenclatural problem with the name of this species. Apparently the name Turbo bidens was not originally applied by Linnaeus to material of this species. See further discussion under "Nomenclature".
The ICZN opinion, number 2176, preserved the name Turbo bidens Linnaeus, 1758, and indicated implicitly that the name Helix papillaris Müller, 1774 was a junior synonym of the same species. However, at this time the meaning of the name Turbo bidens was not fixed with a valid type specimen designation. In 2009 Kadolsky reviewed the nomenclatural history of the name Turbo bidens and concluded that a neotype designation proposed by Falkner et al. (2002) was invalid because it was not based on an existing specimen but on a figure of Papillifera papillaris published by Gualtieri (1742), which did not agree with Linnaeus' description of Turbo bidens, and which Linnaeus did not quote.
