Twenty-six specimens of the meadow vole, Microtus pennsylvanicus (Ord), were obtained by us in Jewell County, Kansas. Three specimens were taken on June 20, 1963 and 22 were captured on November 1, 1963 south of the Republican River at R6W, T2S, SWI/4 Sec. 4. One meadow vole was taken north of the Republican Rivet at R6W, TIS, Sec. 5 on September 27, 1963. To our knowledge this constitutes the first known record for the meadow vole in Kansas. This species has been recorded in northern Missouri (Enders, 1932), south central and southwestern Nebraska (Jones,. In Press), and in eastern Colorado (Anderson, 1956). The nearest locality as shown by Jones (In Press) is 4 mi. N, 2 mi. E of Hastings in Adams County, Nebraska. The collecting sites in Kansas represent a range extension of approximately 55 miles south southeastward of the Nebraska locality. The one specimen north of the Republican River was taken along with 17 prairie voles, Microtus ochrogaster, on the flood plain dominated by smooth brome (Bromus inermis) with some fireweed (Kochia scoparia) and stinging nettle (Urtica procera). Most of the specimens were trapped south of the Republican River in an area adjoining a spring-fed farm pond. The pond extends north and south with a dam located at the south end. The pond is approximately 100 yards long and 40 yards wide at its widest point. Adjacent to the pond, especially at the north end, is a cattail (Typha latifolia) marsh with numerous peach-leaved willows(Salix amygdaloides). Next to the cattails is a very heavy Kentucky bluegrass (Poa pratensis) mat with large bunches of big bluestem (Andropogon gerardi). Interspersed with the bluegrass is some buckbush (Symphoricarpos orbiculatus), and some dense stands of aster (Aster exilis) can be found associated with the cattails. On the higher surrounding ground there is a community of big and little (Andropogon scoparius) bluestem. Along one of the small tributaries leading into the pond, barnyard grass (Echinochloa crusgalli) is dominant. The majority of M. pennsylvanicus were trapped in the communities dominated by bluegrass, cattail, and barnyard grass. Most of the M. pennsylvanicus were taken where sign was evident in the form of grass clippings, but runways were poorly defined. Other
