M. Brock 1957 Dicrostonyx July 16 Barrow, Northern Alaska in two lots of two hundred. Animals for each separate date were placed in separate bags. When the bag containing lemmings caught June 7 was emptied, a Dicrostonyx was among all the Lemmus. This individual was prepared as a study skin. I cannot think how this animal could possibly have gotten mixed in by mistake from anywhere else and is therefore considered as coming from Wainwright proper.
