George Perry’s fossil molluscan taxa, published in the ‘Arcana’(1810-1811)

The fossil molluscan taxa proposed by George Perry in his Arcana are listed and discussed. These taxa, proposed in 1810 and 1811 for shells found mostly in the Paris Basin, with two exceptions have never been cited in a systematic work. The genus-level taxon Aculea Perry, 1810 is shown to be earlier than the synonymous Haustator de Montfort, 1810. ‘Pinus’ Perry, 1811, proposed in a somewhat ambiguous manner and cited as a genus by Sherborn and by Neave, was introduced as Rostellaria pinus, a senior subjective synonym of Clavilithes macrospira Cossmann, 1889. Cassis verrucosa Perry, 1810 is a junior subjective synonym of Cassis cancellata Lamarck, 1803, but is the earliest available name for the species. Conus angulatus Perry, 1810, Aculea angulata Perry, 1810 and Cerithium laevis Perry, 1810 are junior subjective synonyms of Conus deperditus Bruguière, 1792, Turritella imbricataria Lamarck, 1804 and Rhinoclavis striatus (Bruguiere, 1792), respectively. Neotypes are proposed for Cassis verrucosa Perry, 1810, and for Rostellaria pinus Perry, 1811.
