Fig. 41. a. CeUiilomonas rossica, Reuszer. Normal, peritrichous flagella. 



b, c. C. hibula, Reuszer. A single curly flagellum was most common but 

 individuals were also seen with several curly flagella. The arrangement is 

 peritrichous. 



d. C. perlurida, Reuszer. This shows a flagellum with the proximal end of 

 normal curvature and the distal end curly. The wavelength ratio of the normal 

 and curly waves is about 3:1. Normal wavelength, 2.9 microns, curly wave- 

 length, 1.05 microns. 



e. C. perlurida, Reuszer. Long curly flagella, peritrichously arranged. 



f. C. perlurida, Reuszer. A normal and a curly flagellum on same indi- 

 vidual. 



perlurida had an average wavelength of 2.9 microns and those of 

 C. hibulo 2.8 microns. ( See Fig. 41. ) Morphologically C. per- 

 lurida and C. bibuki appear to be identical and could well be con- 

 sidered a species of the genus Flnvobacterium.
