SUMMARY. Twelve carabao in the Philippines were found to be lightly infected with intestinal amoebae. Trophic forms (12 microns in diameter) of this protozoan possessed a definite ectoplasm and a homogeneous endoplasm. They were found only in stained preparations. The nucleus was similar to that of the cyst. All unconcentrated fecal smears contained at least a few cysts (8 microns in diameter). In these forms the cytoplasm usually contained a large vacuole and one or more irregular chromatoidal bodies. The nucleus (2.6 microns in diameter) possessed a pronounced, deeply staining, uniform peripheral ring and a large irregular endosome. There was no periendosomal ring. This amoeba is designated as Entamoeba bubalus , n.sp.
