During a visit to Barro Colorado Island in the Canal Zone in the summer of 1925”, observations in many termites of the family Termitidae, most members of which according to previous examinations contain no Protozoa, resulted in the discovery of small flagellates and amoebae in several species. The most numerous and striking amoebae occurred in Mirotermes hispaniolae Banks and Mirotermes panamaensis Snyder, termites which have wood-boring and wood-feeding habits similar to those of the lower families.1 Previously Cleveland (1923) had found Protozoa in alcoholic specimens of these two species of termites which had been collected from the same locality and preserved in the collections of the U.S. National Museum, but since the Protozoa were in poor condition he was unable to classify them. However, it is probable that they were the same as the amoebae described below.
