Abstract
Summary: A soap-tolerant organism, commonly found in face-flannels and sponges, was compared with Bacterium anitratum, Moraxella Iwoffi var. brevis and Alcaligenes viscosus. These organisms have many characters in common. It is proposed that Bacterium anitratum and related organisms should be included in the family Achromobacteriaceae and that the soap-tolerant organism be considered a new variety of B. anitratum with the provisional name Achromobacter anitratum var. saponiphilum. Some problems of classification of these and similar organisms are discussed.
