K, YABE ; ON TWO NEW KINDS OF RED YEAST. 



Ill Pasteur s solution it forms a faintly pink deposit, but 

 with no film on the surface ; on potato the tint becomes more 

 vivid, probably under the direct influence of the free oxygen. 



In stab-culture in sugar gelatine a moderate growth is ob- 

 served along the needle track ; but these cells remain colourless, 

 while those on the surface assume gradually a pink colour lique- 

 faction of the gelatine does not take place. 



A temperature of 45°C will not kill the cells within 15 

 minutes, but one of 50° will. Alcohol of 5% retards, of stops, 

 development in nourishing solutions. 



The species is named in honour of the well known Japanese 

 botanist Keiske Ito.
