B. rufus (n. sp.), 



B. rosaceus metalloides. 



Since these cultures are slower in development, the pigment 

 appears somewhat later than in the organisms of group I. In 

 young cultures a large percentage of orange is present, and the 

 cultures never grow black, but keep the orange red tone. Here 

 are included "orange red", and "yellowish reddish" cultures.
