60 GENERAL SYSTEMATIC BACTERIOLOGY 



c. Lophotrichic Bactrinius Kendall 



d. Unknown Bacterius Kendall 



C. Spirillaceae: Cells cylindrical, spirally twisted: 



1. Cells rigid, non-motile Spirosoma Migula 



2. Cells motile: 



a. Cell rigid: 



(a) with one or two polar flagella. 



Microspira Schroeter 



(b) Lophotrichic Spirillum Ehr. 



b. Cells flexuous Spirochaete. Ehr. 



D. Chlamydobacteriaceae: Cells enclosed in a sheath: 



1. Cell division always in one plane. . . Streptothrix Cohn 



2. Cell division in three planes, very delicate sheath. 



Phragmidiothrix Engler 



3. As "2", but sheath clearly visible . .Crenothrix Cohn 



4. Cells more or less branched Cladothrix Cohn 



E. Beggiatoaceae: Cells without a sheath, motility by means of an undulat- 



ing membrane. Cells contain sulfur granules 



Beggiatoa Trev. 



Allan J. Smith (1902) follows the Chester (1901) classification 

 consistently. 



Matzuschita (1902) in his Bakteriologische Diagnostik adopts the 

 following simple scheme. 



Matzuschita's Classification of Bacteria (1902) 



Coccaceae: Cells spherical. 



1. Cells in chains Streptococcus 



2. Cells irregularly grouped Micrococcus 



3. Cells in packets Sarcina 



Bacillaceae: Rod shaped Bacillus 



Spirillaceae: Spiral or bent rods: 



Short Vibrio 



Longer, relatively thick Spirillum 



Long, very slender Spirochaeta 



Klocker (translation 1903) in general employed the generic name 

 applied by the one who first named the organism. He recognizes the 

 genera Micrococcus, Pediococcus, Sarcina, Bacterium, Bacillus, Ter- 

 mobacterium, Saccharohacillus, Clostridium and Granulohacier. 



The classification used by Alfred Fischer (1903) in the second edition 

 of his Vorlesungen is given below. 



Fischer's Classification of Bacteria (1903) 



A. Order I. Haplobacterinae. Vegetative body, one-celled, spherical, cylindri- 

 cal or spiral ; single or united to unbranched chains and other growth forms :
