57] STUDIES ON GREGARINES—KAMM 57 



Ellis described the species from western termites. His drawing 

 (my figure 56) compares favorably with that of Leidy except that the 

 posterior end of his is broadly rounded instead of bluntly pointed. The 

 newer specimens are also much larger — 570/x long. Dimensions given by 

 Ellis are 'T. 25/x x 170m, D- 30m x 400m." They correspond with his figure 

 (PI. XVII, fig. 6) if changed to "P. 250m by 170m, D- 300m by 400m. 



This species is considered doubtful because three important characters 

 are lacking, viz. epimerite, cyst and spores. None of the workers has 

 encountered associations.
