V. GENERIC INDEX OF THE COMMONER FORMS OF 



BACTERIA 



Prepared for the Committee by Dorothy F. Holland, 



Department of Public Health, Yale School of 



Medicine 



The following index is not intended to be exhaustive or to deal 

 in any sense with problems of specific identity. The literature 

 has not been comprehensively studied and no attempt has been 

 made to arrive at conclusions in regard to the priority of specific 

 names. The list is simply an index of reference to show how the 

 names of species commonly found in the literature should be 

 changed to correspond with the generic classification suggested 

 by the committee. Many of the specific names quoted are known 

 to be synonyms, and the list is therefore in no sense a check list of 

 valid bacterial species. Our hope is that those who wish to use 

 the committee classification can by reference to this list easily 

 replace the older form of any specific name by the newer one 

 which it should bear in accord with the generic arrangement pre- 

 sented above ; and in particular that it will facilitate the breaking 

 up of the absurdly incongruous aggregates massed together under 

 the older names Bacillus and Bacterium.
