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.
