Banyuls-sur-Mer, 1935. Single printed leaf (21.0 x 13.5 cm). Handwritten, signed and dated.

Handwritten letter on the stationery of the Faculté des Sciences de Paris Laboratoire Arago Banyuls-sur-Mer, by the French malacologist Alice Pruvot-Fol (1873-1972) to her colleague, the French marine biologist, ichthyologist, parasitologist, and director of the Service des Pêches Coloniales, Robert Philippe F. Dollfus (1887-1976). He 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 obituary in the Journal de Conchyliologie 114(3-4), p. 131. In this letter, Pruvot-Fol thanks Dollfus for trying to research some information, to no avail. She continues with a note on the progress made by her son, who became a geologist and finally she writes that she has obtained the opisthobranch library of another French malacologist [Albert Jean-Baptiste Marie Vayssière (1854-1942)], yet with some gaps remaining. A few years earlier, Pruvot-Fol had described the opisthobranchs collected by Dollfus during his "Mission Robert Ph. Dollfus en Égypte (Décembre 1927-Mars 1929)".
