The Dutch malacologist M.M. Schepman corresponded with J.C. Melvill and J.R. le B. Tomlin in Great Britain. Melvill assisted Schepman with work on the collection of the Rijksmuseum van Natuurlijke Historie in Leiden, resulting in the description of Latirus eppi. In one of two articles on the matter, Melvill named Schepman as co-author ( Latirus eppi Melvill & Schepman, in Melvill, 1891), in the other he didn’t (Latirus eppi Melvill, 1891). As the second article is earlier dated, the correct name is Latirus eppi Melvill, 1891. Melvill also assisted Schepman with his work on mollusks of the Siboga Expedition. In return for his support Schepman named six species after Melvill: Latirus melvilli, Eulima melvilli, Argyropeza melvilli, Seguenzia melvilli, Scala (Clathrus) melvilli and Surcula melvilli. Melvill in return named two species after Schepman: Argyropeza schepmaniana and Epitonium schepmani. The contact with Tomlin probably also started with the Sibogamaterial. Tomlin, being a specialist in nomenclature, discovered that Marginella abyssicola Schepman, 1911 had to be renamed and introduced Marginella schepmani as nomen novum. In 1920 Tomlin bought malacological literature from Schepman at an auction. Today the combined Melvill-Tomlin Collection is in the National Museum of Wales, including a letter and a postcard written by Schepman. The postcard was addressed to Smith, who probably handed the card over to Tomlin. The letter was written to Del Prete, from whom Tomlin bought some letters, which Del Prete had received from several collegues all over the world. No letters from Schepman to Melvill and/or Tomlin could be traced.
