Lamare-Picquot (1785-1873) is a famous french explorator: Mauritius, Indes, Turkey, and also North America from where he tried to introduce in Europe some species, e.g., Psoralea esculenta (the “Picquotiane”) instead potatoes… Lamare-Picquot was a great naturalist, also ethnologist, correspondent of Academy of Sciences and of the Muséum national d’histoire naturelle, in Paris. He obtained some fame because of his theory that reptiles could suckle the milk from udder, a theory classified under the category “prejudices”, by Duméril and Bibron. Lamare-Picquot has given many collections to MNHN, while others were sold (e.g., to BMNH) to finance his voyages.
According to Chaigneau (1982), who consulted the National Archives (AJ 15-548), we learn that his zoological collections were shared at the end of his life between MNHN and different universities:
In Lyon University, we found in the general collection a shell, which was apparently obtained by this sharing in 1865.
