Rumen ciliate compositions were surveyed on the Bali cattle and the water buffaloes in Indonesia. As the result of survey, 15 genera including 45 species with 15 formae and 11 genera including 37 species with 1 2 formae were identified from the Bali cattle and the water buffalo, respectively. Of the ciliates detected from the Bali cattle, one new entodiniid species was recognized, then described as Entodinium javanicum sp. nov. The ciliate compositions between these two species of hosts were similar to each other, or 30 species detected were common. From the comparison of these faunae with that of the domestic animals fed in neighbouring area, the presence of geographical distribution of the rumen ciliates was strongly indicated. Some ciliate species detected only from the animals of Southeast Asia were discussed on the phylogenetical relationship to the host species. The average density of ciliates per 1 ml of the rumen fluid was 7.8 × 10^4 in the Bali cattle and 1.5 × 10^4 in the water buffaloes, respectively. The ciliates of the genus Entodinium was the most predominant both in the Bali cattle and the water buffaloes.
