摘要：
Numerous occurrences of undescribed Paleozoic polyplacophorans have been located, and new taxa of Silurian, Mississippian, and Permain specimens have been recently described, problems commonly exist in classifying isolated plates at thr species level. Sizes and patterns of aesthetes show some differences in plate microstructure between Palcozoic and modern taxa. Recently proposed classifications indicate differences of opinion concerning relationships anti inclusion of non-polyplacophoran taxa. A possible, but incomplete, phylogenetic scheme at thr family level is presented. Plasiochiton curiosus n. gen. and sp, is described from the Devonian of Pennsylvania.
