New genera of Paleozoic Polyplacophora (Mollusca)

Abstract

The opportunity to study some of de Koninck's (1883) type specimens from the Institut Royal de sciences Naturelle de Belgique (RMNS), specimens from the British Museum of Natural History (BMNH), and from the Museum of Comparative Zoology, Harvard University (MCZ) has provided insight into the taxonomic relationships of some polyplacophoran taxa. It is evident that errors have occurred in relating various specimens to taxa which differ significantly. Two examples of this related to a Devonian species in Germany and a Permian species in the United States National Museum of Natural History (USNM) are clarified and illustrated.
