The occurrence of the following mammals was listed by Taylor and Shaw, _Mammals and Birds of Mount Rainier National Park_, 1927, as follows:
Muskrat, _Ondatra zibethicus osoyoosensis_ (Lord). “In lower portions of the park; apparently now trapped out within its boundaries.” Norway Rat, _Rattus norvegicus norvegicus_ (Erxleben). “Here included on the authority of J.

It is believed that the three species above are not now found within the park.
