‎Lemche, H.‎
‎A New Deep-sea Mollusc of the Cambro-Devonian Class Monoplacophora.‎

‎ 1957 9 p., 4 figs, stapled. Published in: Nature.On May 6, 1952, ten living specimens of an extraordinary mollusc were discovered. While trawling off the Pacific coast of Costa Rica, the Danish deep-sea "Galathea" expedition hauled these specimens to the ocean surface from a depth of 3590 meters. They were given the name Neopilina galathea and their discovery has been described as "the most dramatic one in the history of malacology." Before that date these limpet like shells were only known as fossils and this was the first time a living representative of the class Monoplacophora was found. It's nearest fossil relative lived in the Silurian 400 million years ago. This is a reprint of the first original description of by Lemche in Nature. On the top right corner of the first page is a stamp reading: ''With the compliments of the author''. We added: Lemche, 1962. The primitive Mollusc that Emerged from Our Oceans (7 p., 2 figs, printed wrappers, published in: Scientia).Needless to say that this paper has great historical value.‎
