of body; in Cryptotermes hermsi and many species of the genus; also 

 species of Glyptotermes, Rugitermes, and Procryptotermes. 



Genus Macrotrichomonas Grassi. Large; 3 anterior flagella; trail- 

 ing flagellum well developed, 1-1.5 times the body length; cresta a 

 broad internal membrane, 21-86^ long; parabasal body coiled around 

 the axostyle, 1-13 times; in termite gut. Several species (Kirby, 

 1942). 



M. pulchra G. (Fig. 142, d). 44-91m by 21-41/i; traihng flagellum 

 band-form; cresta large; parabasal body coiled closely 4-10 times; 

 in Glyptotermes parvulus, and many other species of the genus. 



Genus Metadevescovina Light. Moderately large; 3 anterior 

 flagella; a short trailing flagellum; cresta small; parabasal body 

 loosely coiled around axostyle; anterior end of axostyle in a loop;, 

 in termite gut.

 hardi. 



Genus Caduceia Franga. Large; 3 long anterior flagella; trailing 

 flagellum slender, shorter than body; cresta relatively small, l-12ju 

 long; parabasal body coiled around axostyle 2-20 times; nucleus 

 relatively large; in termites. Several species (Kirby, 1942). 



C. hugnioni Kirby (Fig. 143, a). 48-80m by 18-40/i; in Neoterrnes 

 greeni. 



Genus Pseudodevescovina Sutherland. Large; 3 short anterior 

 flagella; one short trailing flagellum; axostyle stout; cresta of moder- 

 ate size; parabasal body large, divided into a number of attached 

 cords; in termite gut. 



P. uniflagellata S. (Fig. 143, h). 52-95^ by 26-60/x; 3 delicate 

 flagella, 30m long; trailing flagellum a little stouter; cresta 11-20^ 

 long; main parabasal body C-shaped, with 7-19 attached cords; in 

 Kalotermes insularis. 



Genus Bullanympha Kirby. Flagella and cresta similar to those in 

 Pseudodevescovina; axostyle similar to that in Caduceia; proximal 

 part of parabasal body bent in U-form around the nucleus and at- 

 tached voluminous distal portion coiled around the axostyle; in 

 termite gut. 



. B. silvestrii K. (Fig. 143, c). 50-138m by 35-100^; cresta about 5.8m 

 long; distal portion of parabasal body coils around axostyle about 

 twice ; in Neotermes erythraeus. 



Genus Gigantomonas Dogiel {Myxomonas D.). Medium large; 3 

 short anterior flagella; a long and stout trailing flagellum; cresta 

 conspicuously large; large axostyle; in termite gut. According to
