192 PALEOBOTANY [BoT. Absts., Vol. VIII, 



de Tausz et Peter. [On the characters common to Bacterium /?, the symbiont of Clostridium 

 Paetorianum of Winogradsky and Bacterium aliphaticum non liquefaciens of Tausz and Peter.] 

 Compt. Rend. Acad. Sci. Paris 171: 1089-1091. 1920. — A comparison is made between the 

 morphological and physiological characteristics of Bacillus 0, which is a symbiont of Clo- 

 stridium pastor ianum, with those of Bacillus aliphaticum non-liquefaciens. The conclusion 

 is reached that they are either closely related strains of the same species or that they are 

 the same strain. The chief points of distinction seem to be such as are related to the life 

 habits of the two, symbiosis in the one case and independent development in the other. —

 Jr., L. a. Rogers, and G. H. Smith. The families and genera of the bacteria. Final report 

 of the committee of the Society of American Bacteriologists on characterization and classifica- 

 tion of bacterial types. Jour. Bact. 5: 191-229. 1920. — The report is divided into 4 sections. 

 In section I, the introduction, reference is made to the preliminary report of the Committee 

 in 1917 and the changes made in that report are noted, namely, (1) the family Mycobac- 

 teriaceae has been elevated to the rank of an order, Actinomycetales, with 2 families, Actino- 

 mycetaceae and Mycobacteriaceae; to the first family have been added 2 genera, Actino- 

 bacillus and Erysipelothrix, the genus Nocardia having been omitted; to the second family 

 has been added the genus Pfeifferella. (2) The family Nitrobacteriaceae has been divided 

 into 2 tribes and the name of the genus Mycodervia has been changed to Acetobacter. (3) In 

 the Coccaceae the genus Neisseria has been placed in a separate tribe; the genus Albococcus 

 is united with Staphylococcus; and the new genera Diplococcus and Leuconostoc are added. 

 (4) The Bacteriaceae are divided into 7 tribes and the new genera Erythrobacillus, Chromo- 

 bacterium, Zopfius, and Proteus are added. (5) The family Lactobacillaceae is reduced to 

 the rank of a tribe of the Bacteriaceae. In section II are given some specific recommenda- 

 tions, including a list of 16 genera the names of which are recommended for adoption. In 

 section III is given the outline of bacterial classification, including characteristics of the 

 orders, families, tribes, and genera; 38 genera are included with the name of the type species 

 for each genus. Section IV contains an artificial key to the families and -genera. Section 

 V consists of a generic index of the commoner forms of bacteria with the names of the common 

 species annexed to their proper generic names. — Chester A. Darling.
