Léopold de Folin

De Folin wrote on Caecidae for the reports published following the Challenger expedition of 1872-1876.
With Henri Milne-Edwards's son Alphonse, de Folin carried out a survey of the Gulf of Gascony. He worked on board the ''Travailleur'' (a paddle-wheel aviso) in 1880, and on board the ''Talisman'' in 1883, for trips to the Canary Islands, the Cape Verde Islands and the Azores.
De Folin also described the genus ''Oceanida'' of sea snails in the family ''Eulimidae''. Provided by Wikipedia
