POLYMASTIGINA 397 



body, and an axial filament. Janicki called this complex karyomasti- 

 gont (Fig. 170, a) and the complex which does not contain a nucleus, 

 akaryomastigont (Fig. 170, e). This group includes the forms which 

 inhabit the gut of various species of termites, most probably as 

 symbionts. 



Genus Calonympha Foa. Body rounded; large; numerous long 

 flagella arise from anterior region; numerous nuclei; karyomastigonts 

 and akaryomastigonts; axial filaments form a bundle; in termite 

 gut (Foa, 1905). 



C. grassii F. (Fig. 170, a). 69-90/x long; in Cryptotermes grassii. 



Genus Stephanonympha Janicki. Oval, but plastic; numerous 

 nuclei spirally arranged in the anterior half; karyomastigonts; axial 

 filaments form a bundle; in termite gut (Janicki, 1911). 



S. nelumbium Kirby (Fig. 170, b). 45)u by 27m; in Cryptotermes 

 hermsi. 



Genus Coronympha Kirby. Pyriform with 8 or 16 nuclei, arranged 

 in a single circle in anterior region; 8 or 16 karyomastigonts; axo- 

 styles distributed; in termite gut (Kirby, 1929, 1939). 



C. clevelandi K. (Fig. 170, c). 25-53^ by 18-46/*; in Kalotermes 

 clevelandi. 



Genus Metacoronympha Kirby. Pyriform; one hundred or more 

 karyomastigonts arranged in spiral rows meeting at the anterior 

 end; each karyomastigont is composed of nucleus, blepharoplast, 

 cresta, 3 anterior flagella, a trailing flagellum, and an axostyle; axo- 

 style as in the last genus; in termite gut (Kirby, 1939). 



M. senta K. (Fig. 170, d). 22-92 M by 15-67ju; karyomastigonts 

 about 66-345 (average 150) in usually 6 spiral rows; in Kalotermes 

 emersoni and four other species of the genus. 



Genus Snyderella Kirby. Numerous nuclei scattered through the 

 cytoplasm; akaryomastigonts close together and extend through the 

 greater part of peripheral region; axial filaments in a bundle; in 

 termite gut (Kirby, 1929). 



S. tabogae K. (Fig. 170, e). Pyriform; rounded posteriorly; bluntly 

 conical anteriorly; 77-172ju by 53-97/*; in Cryptotermes longicollis.
