Taxonomic procedure, nomenclature

Abstract

Taxa above family rank, not governed by the rules of zoological nomenclature, are provided with short references to date, authorship, and emendations. This is done in the taxonomic headings, following the abbreviated style adopted by the Treatise on Invertebrate Paleontology (Geological Society of America and University of Kansas Press) and explained in the editorial preface to each volume. The same procedure is employed for names of family rank. Families or subfamilies which have been recently revised, or for which a new interpretation is adopted, are followed by a taxonomic summary and discussion.
