GenusMesojoeniaGrassi. Body large. Flagellar tuft is spread 

 over a wide area. Distinct axostyle, bent at the posterior end. 

 Parabasal bodies two in number. 



Mesojoenia decipiens Grassi. In the termite, Kalotermes. 



Family 4 Hoplonymphidae Light 



Two flagellar tufts; each arises from a plate near the an- 

 terior end of the slender body which is protected by a highly 

 developed pellicular armor. 



Genus Hoplonympha Light. Body slender fusiform, covered 

 with thick, rigid pellicular armor. Each tuft of flagella arises 

 from a plate connected with blepharoplasts at the anterior end. 

 Nucleus near the anterior extremity, more or less triangular in 

 form. 



Hoplonympha natator Light (Fig. 66, a, b). In the intestine 

 of the termite, Kalotermes simplicicornis. 



Family 5 Staurojoeniidae Grassi 



Four flagellar tufts arise from the anterior end. 



Genus Staurojoenia Grassi. Body pyriform. Spherical 

 nucleus central. Four flagellar tufts from the anterior end. In- 

 gest wood fragments. 



Staurojoenia assimilis Kirby (Fig. 66, c). In the intestine of 

 the termite, Kalotermes minor. 



Family 6 Kofoidiidae Light 



Flagellar tufts are composed of several loriculae (per- 

 manently fused bundles). No axostyle, no parabasal body. 



Genus Kofoidia Light. Body spherical. Between the oval 

 nucleus and the bases of the flagellar tufts, there occurs a chro- 

 matic collar. Wood fragments as food. 



Kofoidia loriculata Light (Fig. 66, d, e). In the termite, 

 Kalotermes simplicicornis. 



Family 7 Trichonymphidae Kent 



The body is divisible into two regions: anterior and poste- 

 rior. The surface of the anterior portion is differentiated into 

 one or two thick ectoplasmic layers, densely traversed by 

 numerous flagella. There is an "axial core" or "head organ" at
