OJO: TITULO MUY LARGO
In 1949, for the Museum of Natural History of the University of Kansas, Mr. John A. White collected two specimens of the species _Microtus montanus_ in the Bitterroot Valley of Montana, that did not fit the description of any named subspecies. These were laid aside until we could examine the additional specimens from Montana in the Biological Surveys collection in the United States National Museum, some of which previously had been reported by Bailey (N. Amer. Fauna, 17: 31, June 6, 1900) under the name _Microtus nanus canescens_ Bailey [ = _Microtus montanus canescens_]. Our examination reveals that the animals from the Bitterroot and Flathead valleys belong to an heretofore unrecognized subspecies which is named and described below.
