SURVEY OF CLASSIFICATIONS OF BACTERIA 19 



The second complete outline drawn up by Janke (Oesterr. Bot. Zeitschr., 

 78, 1929, 108) is similar to the classification employed by Lehmann and 

 Xeumann (Bakt. Diag., 2 vols., 7th ed., Miinchen, 1926-27). He follows 

 Enderlein in placing Azotohacter in close association with the spore-forming 

 rods. No new generic terms are suggested. His sub-groups of the genus 

 Bacterium are even more closely similar to the genera used in the present 

 edition of the jNIaxual than are the sub-groups of Lehmann and Neumann.
