ABSTRACT Very little work has been done on the protozoa of Australian termites except for the observations of Grassi (1917), who described the faunas of Porotermes adamsoni Frogg., Coptotermes lacteus Frogg., and a species of Schedo- rhinotermes, and those of Duboscq and Grassé (1927), who worked on Calotermes iridipennis Frogg.
