Stockholm, 1948-1950. Two printed leaves (29.2 x 22.8 cm  and 29.7 x 21 cm ). The first letter typed, with hand-written signature and additional handwriting; the second entirely handwritten, signed and dated.
Two letters, on the stationery of the Naturhistoriska Riksmuseum in Stockholm, from the Swedish malacologist Nils Hjalmar Odhner (1884-1973) 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 these letters, Odhner discusses several topics, including the whereabouts of captain C. O. Johnson, who collected cetaceans, a forthcoming paper on the landsnails of the Galapagos Archipelago, etc. First (1948) letter frayed at right margin, otherwise very good.
