THE GENUS ALBOCOCCUS 199 



all have been isolated from the human or animal body. 

 Acid production and a positive reaction to the Gram stain 

 are recorded, wherever these characters are recorded at 

 all. The following list includes the "species" tabulated 

 by Migula and Chester which appear to be merely syno- 

 nyms of Alb. pyo genes.

As pointed out in Chapter VIII, some of the white 

 cocci of the skin, which come under our general type of 

 Alb. pyo genes, possess distinct pathogenic powers, and
