232 RELATIONSHIPS OF THE COCCACE^ 



Good to very heavy surface growth, of yellow color. Reaction 

 in dextrose broth faintly acid, in lactose broth alkalin or 

 faintly acid. Gelatin slowly liquefied. Nitrates not 

 reduced. 



The following names of yellow, liquefying sarcinae 

 appear to be synonyms of S. flava: S. baccatus, Migula; 

 S. bicolor, Kern; S. canescens, Stubenrath; S. equi, Stu- 

 benrath; S. flavescens, Henrici; S. gigantea, Kern; 5. 

 lactis, Chester ; S. Lembkei, Migula; S.liquefaciens,Fra,nk- 

 land; S. livido-lutescens, Stubenrath; S. mirabilis, Kern; 

 S. Glens, Henrici; S. radiata } Kern; S. sub/lava, Ravenel; 

 S. superba, Henrici; 5. variabilis, Stubenrath. 



It is somewhat interesting to note that none of Lindner's 

 and Gruber's brewery sarcinae fall in this group. Henrici's 

 cultures were from cheese, and Stubenrath's and Kern's 

 from the stomachs and intestines of mammals and birds. 



Besides these typical forms there are a few descriptions 

 in the literature, of similar organisms which, in the light 

 of present knowledge, are harder to classify. The most 

 important of these is the orange sarcina described by 

 Fliigge (1886) under the name S. aurantiaca. S. aures- 

 cens (Henrici), Gruber, and S. aurea, Mace, apparently 

 represent the same form. In our series of five hundred 

 cultures we found one hundred and forty-seven orange 

 micrococci, one hundred and thirty-seven yellow sarcinae, 

 and only eleven orange forms which showed the packet 

 grouping. The latter combination appears, therefore, 

 to be a rare one. In other biochemical characters our
