The species name typhosa should be 

 used for the typhoid organism when it 

 is placed in any genus other than Ba- 

 cillus in spite of the earlier use of this 

 species name by Klebs for a different 

 organism. There are two reasons for 

 this: (a) This appears to be the proper 

 course to follow under International 

 Rules of Nomenclature (See Art. 54, 

 p. 54) and (b) there is less chance for con- 

 fusion regarding the nature of this or- 

 ganism among English-speaking persons 

 who may carelessly interpret typhi as the 

 name of a typhus rather than a typhoid 

 bacillus.
