He created his own classifying system to arrange the molluscs in his collection, a problem since it was a very particular system opposed to that of his friend, Draparnaud. His collection included 62 species not appearing in l'Histoire naturelle des Mollusques terrestres et fluviatiles de la France (the Natural History of Terrestrial and Fluviatile Molluscs of France) of Draparnaud and was consulted by Gaspard Louis André Michaud (1795-1880) when he wrote the supplement to this work.
