Dicrostonyx richardsoni Merriam. This lemming, which is closely related to D. hudsonius of Labrador, was described from specimens taken at Fort Churchill, where it is abundant. Farther to the north it is represented by closely related forms whose ranges are among the most northerly of all land animals. Hearne's excellent account of this species has been confirmed in almost every particular by later observers.
