Paris, 1931. Single printed leaf (27.0 x 21.0 cm). Hand-written, signed and dated.

Hand-written letter (dated 10 May 1931), on Muséum d'Histoire naturelle stationery, by the French malacologist and oyster culture specialist Gilbert Ranson (1899-1972), to the French marine biologist, ichthyologist, parasitologist, and director of the Service des Pêches Coloniales, Robert Philippe F. Dollfus (1887-1976). Dollfus was a son of the malacologist Gustave Frédérique Dollfus (co-author of the famous Les mollusques marins du Rousillon), and was interested in Mollusca himself. Paul Henri Fischer wrote his necrologie in the Journal de Conchyliologie 114(3-4), p. 131. In this letter, Ranson asks Dollfus for a list of current members of the International Commission of (Zoological) Nomenclature. Probably he wanted to shoot them all. Weak horizontal and vertical fold in the middle, otherwise very good.
