FAMILY: BODONIDiE 



The flagellate multiplies by longitudinal fission after division of the 

 kinetoplast and nucleus. The organism is readily cultivated in hay and 

 other infusions, and it will also multiply on the surface of agar plates. 

 According to Sinton (1912), division of the flagellate takes place once in 

 every four hours, so that in a short time very large numbers are present 

 in the medium. 



Bodo edax Klebs, 1892. — This is another species which may appear in 

 faeces, though less commonly than B. caudatus (Fig. 250). It is slightly 

 smaller than B. caudatus, and more stumpy in form. The two flagella are

approximately equal in length, and both are longer than the body. The 

 organism was studied by Kiihn (1915). In its method of multiplication 

 and cyst formation it is very similar to B. caudatus. 



Genus: Rhynchomonas Klebs, 1892. 

 Stokes (1888) in America described as Heteromita tiasuta a flagellate 

 which was ovoid in shape and provided with one trailing flagellum, over 

 the point of origin of which there exteiided a digital process. Klebs 

 (1892) created the genus RhyncJiomonas for this organism. It was seen 

 as a free-living flagellate in fresh water by Stokes (1888) and Belaf (1915), 

 and in salt water by Griessmann (1913), while Parisi (1910) obtained it as a
