Fig. 23. a. Cellvibrio vulgaris, Reuszer 122. The soma is straight with 

 rounded ends and with a single polar flagellum of relatively short wavelength. 



b. C fulvus, Reuszer 18. The soma is typically vibrio shaped with a single 

 polar flagellum of relatively long wavelength. 



c. Cellvibriv sp., Haynes B-668. Single polar flagellum with the long 

 wavelength. In this individual the soma is only very slightly curved. 



d. C. vulgaris, Reuszer 122. Polar monotrichous flagella with the longer 

 wavelength. 



e. C. fulvus, Reuszer 102. This shows the same type of organism illustrated 

 in a. In addition to the individuals with the single polar flagellum the rather 

 unusual situation pictured was quite common. With most bacteria in which 

 the new flagella develop before cell division is completed, bipolar or amphi- 

 trichous flagellation is produced. In other words, the distal ends of the daugh- 

 ter cells usually carry the flagella. With the organism pictured it appears as 

 if the region of cell division develops the new flagella. 



f. C. fulvus, Reuszer 102. Polar monotrichous flagellation of same type 

 shown in b.
