Abstract
Due to recent studies and to recommendations made by various taxonomic subcommittees, the descriptions of several genera of anaerobic, nonsporing bacilli were emended and a number of species with these characteristics were reclassified. Because the resultant new names and combinations and the author citations for them were not clearly indicated when the new names and combinations were originally introduced, they are listed here for the sake of clarity. In addition, five new combinations (Fusobacterium aquatile, F. stabile, F. perfoetens, Eubacterium endocarditidis, and E. helminthoides) and a new name (Eubacterium helwigiae) are proposed herein.
