Extract

1. A description of the morphology and life history (excluding metacystic development) of Entamoeba muris is given.

2. The descriptions of species of amoebae found in rats (Rattus norvegicus and R. rattus) and mice (Mus musculus) by previous authors are critically discussed, and it is concluded that one species, Entamoeba muris, is present.

3 Experiments on cross-infection of rats and mice with E. muris are described, together with observations on the course of these infections.

4. The transference of an amoeba morphologically similar to E. muris from Cricetus auratus to rats and mice is described.

5. An account is given of unsuccessful attempts to establish an infection of Entamoeba coli in rats and mice.

6. Observations on the incidence and hostrestriction of E. muris are discussed.

7. The affinities of E. coli and E. muris are discussed and it is concluded that, although E. muris resembles E. coli morphologically, it differs from E. coli on physiological grounds.
