I studied the fauna and flora of Kagamiike, a pond situated in front of the Daibutsuden, the Great-Budda-House, of Todaiji-Temple, Nara. The pond is inhabited by a number of Ischikauia steindackneri SAUVAGE, the fish, which is herbivorous and eats water plant. In the pond there is no water plant now, but we find on the bottom a thick layer of Aphanothece sp. The characteristics, which we recognized in the plankton community of this pond, are as follows : (1) The number of species is poor. (2) The annual fluctuation is small. (3) The dominant species remain almost always the same. Zooplanktonic dominant is Diaptomus japonicus and phytoplanktonic dominants are Melosira spp. (Fig. 3 shows the annual fluctuation of the calculated volume of each plankton species.) The micro-organisms in the bottom mud are shown in the table 3 ; the species are almost the same as those of phytoplankton.
