Reflexions on the Monoplacophoran, Neopilina galatheae Lemche

THE discovery of the living representative of the Monoplacophora, of which a preliminary account by Dr. H. Lemche was published in Nature of February 23, p. 413, is a zoological event of the first order. To a malacologist, at any rate, these dredge hauls off the west coast of Mexico which secured no less than ten specimens with three extra shells of Neopilina galatheae in themselves alone more than justify the voyage of the Galathea around the world.
