oblique rows of short fiagella; in termite gut (Grassi and Foa, 1911). 



P. grassii Koidzumi. In Coptotermes formosanus; spindle-form; 

 200-300^ by 50-1 20/x (Koidzumi, 1921). 



Genus Deltotrichonympha Sutherland. Triangular; with a small 

 dome-shaped "head"; composed of 2 layers; head and neck with long 

 active fiagella; body fiagella short, arranged in 5 longitudinal rows; 

 fiagella absent along posterior margin; nucleus large oval, located 

 in anterior third; cytoplasm with wood chips; in termite gut. One 

 species. 



D. operculata S. Up to 230/* long, 164/* wide, and about 50/x thick; 

 in gut of Mastotermes darwiniensis; Australia. 



Family 7 Eucomonymphidae Cleveland et al.

 arranged in 2 (longer rostral and shorter post-rostral) zones; rostral 

 tube very broad, filled with hyaline material; nucleus at base of 

 rostrum; in gut of Cryptocercus punctulatus.

 metameric appearance; each ridge with a single row of fiagella; an- 

 terior end complex, containing a nucleus; reproduction by longitudi-
