Artikelbeschreibung des Verkäufers

All 35 Buccinum names, including 5 names indicated by a single character, described from Newfoundland by Theodor Anton Verkr?zen in the years 1878 to 1884 are discussed. Their original descriptions are translated from German to English. Type material of 24 of them is figured. In addition, shells connected to 14 manuscript names are figured. Part of the type material is preserved in the Naturmuseum Senckenberg, Senckenberg Forschungs_institut (SMF, Frankfurt am Main, Germany) and was already discussed by Kobelt (1883) and Zilch (1969). The whereabouts of the remaining type specimens remained unknown until we discovered them recently in the Natural History Museum (NHMUK, London, United Kingdom), where most of them were acquired in 1911 as part of the Museum Normanianum (Alfred Merle Norman, 1831-1918). In the present paper we figure these type specimens: the ones from SMF for the first time photographed in colour, the ones from NHMUK for the first time ever. We compare these species and forms with each other and with similar species, trying to ascertain their status. Our purpose is to improve the systematic knowledge and nomenclatural stability, hoping to reduce the chaos that hampers the systematics of the genus Buccinum. In particular, the identity and natural history of Buccinum inex_haustum Verkr?zen, 1881 is investigated, a lectotype is selected and the taxon is compared to other species and to interpretations thereof by subsequent authors. We place B.?meridionale Verkr?zen, 1884 in synonymy with B.?inexhaustum instead of with B.?undatum. Furthermore, we confirm B.?gouldii Verrill, 1882 being a junior synonym of B.?inexhaustum. The type material of B.?variabile is found to be heterogeneous, therefore a lectotype is selected to clarify its identity in accordance with the original description, but no nomen novum is produced for this junior homonym. We confirm B.?amaliae Verkr?zen, 1878 and B.?conspicuum Verkr?zen, 1878 being synonyms of B.?undatum Linnaeus, 1758. We confirm B.?elegans Verkr?zen, 1878 being a synonym of B.?terraenovae Beck in M?rch, 1867. In addition, we list the historical details that we could retrieve about Theodor Anton Verkr?zen?s life, to offer the reader a broader context. 94 pp., 71 figs, 9 plates, br. 4.…
