The surface structures of rumen ophryoscolecid protozoa in cattle were studied. Various forms of body surface striations were observed, as were species differences which could be classified by optical microscopy, as in the previous study on the rumen ciliates in sheep by two of the authors (Imai and Tsunoda, 1972). Striation forms were similar among individuals identified as the same species but from different hosts. In these results, it is concluded that forms of body striations may be used effectively in discussion of the taxonomy of the ophryoscolecid protozoa. It is considered that it might be reasonable to revise the classification of species classified hitherto by means of the number of caudal spines as mentioned by Lubinsky (1957a), since the form of body striations of E. lobosospinosum and of E. caudatum were almost same. Furrow-like structures were observed on the surface between two ciliary zones of Ep. caudatum, which had no operculum, as well as those of the operculum of Er. bovis. The excretory pore was found in E. caudatum and in Ep. caudatum, but its shape differed from one species to the other. A new pore was recognized at metaphase in binary fission of the ciliate.
