Phenacomys intermedius mackenzii Preble
Lemming Mouse
Phenacomys mackenzii Preble, Proc. Biol. Soc. Washington, 15:182, August 6, 1902. (Type from Fort Smith, Slave River, Mackenzie, Canada.)
Phenacomys intermedius mackenzii Crowe, Bull. Amer. Mus. Nat. Hist, 80:403, February 4, 1943.
Specimen examined.—One from Yukon Territory: SE end Dezadeash Lake.
Remarks.—A subadult taken only a few miles from the Alaskan border in Yukon Territory constitutes an extension of the known range of this species to the northwest. The mouse is evidently rare or irregular in its distribution since Alcorn did considerable trapping in the area from which only one was taken.
