CLASSIFICATION OF BACTERIA 113 



common gelatinous secretion similar to a capsule. The cells 

 are nonmotile. 



Genus : Thiosarcina Winogradsky. 



The colonies form packets similar to the genus Sarcina of 

 the Eubacteria. The cells are nonmotile. 



II Subfamily Lamprocystaceae. 



The cells are formed into families. Cell division takes place 

 first in three, then in two directions of space. 



Genus : Lamprocystis Schroter. 



The cells in the beginning are solid, then hollow, becoming 

 perforated like a net. They separate into small groups and 

 become motile. 



III Subfamily Thiopediaceae. 



The cells are united into colonies. Cell division takes place 

 in two directions of space. 



Genus : Thiopedia Winogradsky. 



The families are formed similar to tubes and are composed 

 of cells arranged in fours and capable of motility. 



IV Subfamily Amcebobacteriaceae. 



The cells are united into colonies. Cell division takes place 

 in one direction of space.
