An adult female from Dundy County provides the westernmost record of distribution of the species in North America. The animal was trapped on November 1, 1952, in association with Microtus pennsylvanicus modestus in a marshy area at the Rock Creek State Fish Hatchery on spring-fed Rock Creek. The pelage on the back is notably darker than in S. c. gossii, and resembles S. c. paludis from the Cimarron River drainage in Meade County, Kansas, but in the sum total of its characters it most closely resembles S. c. gossii among named subspecies.
Mustela rixosa campestris Jackson. Least Weasel.—The least weasel occurs in eastern and central Nebraska (see Swenk, 1926:313-330 and Hall, 1951:192) but is known by only a single specimen from each locality of record save for the area around Inland, Clay County (Swenk, op. cit.). Additional records of the distribution of this mustelid in Nebraska are: Hastings, Adams County, 1 (HM); Schuyler, Colfax County, 1 (NGFPC); Goehner, Seward County, 1 (NSM); 10 mi. S of Ord, Valley County, 1 (NGFPC). The last mentioned specimen, a skull only, was obtained from a pellet of an unidentified raptorial bird.
