194 COMMITTEE REPORT 



Azotobacter. The name Acetobacter has been substituted for 

 Mycoderma to characterize the vinegar organisms. 



Among the Coccaceae a new tribe was created for the genus 

 Neisseria. The genus Albococcus is united with Staphylococcus 

 and the new genera Diplococcus and Leuconostoc are added. 



The Bacteriaceae are divided into seven tribes: Chromobac- 

 tereae, Erwineae, Bactereae, Lactobacilleae, Pasteurelleae, Hem- 

 ophileae, and Zopfeae, and the new genera Erythrobacillus, Chro- 

 mobacterium, Zopfius, and Proteus are added. The Lactobacil- 

 laceae, originally recognized as a distinct family, are thus classed 

 as a tribe of the Bacteriaceae. 



For the convenience, particularly of students, we have pre- 

 pared in section IV of this report an artificial key to the families 

 and genera of the Actinomycetales and the Eubacteriales, w r hich 

 we hope may be of value. It should be possible to place a key of 

 this kind in the hands of a student and enable him at least to 

 determine the general generic group to which any organism be- 

 longs. In the case of certain genera the specific types can be 

 easily identified by reference to monographs such as those of 

 Wenner and Rettger (1919) on Proteus, Ford (1916) on Bacillus, 

 Winslow, Rothberg and Parsons (1920) on Staphylococcus, and 

 Winslow, Kligler and Rothberg (1919) on Bacterium. 



Finally in section V of this report we have presented a generic 

 index of the commoner species of bacteria with the names ordin- 

 arily used in the texts and with the new nomenclature indicated 

 by the proposed classification. This list has been prepared by 

 Miss Dorothy F. Holland of the Department of Public Health 

 of the Yale School of Medicine. It is not intended to be exhaus- 

 tive or to deal in any sense with problems of specific identity, 

 but merely to serve as an index of generic reference for the more 

 familiar types. 



II. SPECIFIC RECOMMENDATIONS 



The classification presented by the committee, the key and the 

 generic index, as stated above, represent merely the consensus of 

 opinion of the members of the committee as corresponding to the 

 most natural system of classification indicated by present knowl-
