Bondo 1934 Microtus montanus July 14 [illegible], 8900 ft., Mt. Grant, Mineral Co. Nevada. caught two specimens in runways in a grassy bog near placer mine. Some of the runways showed Microtus signs and had bits of cut grass. Some of them were in wet ground and some of were in higher sod. Set 4 trap, but only two Microtus fell victims in my traps. These specimens were nearly black. (Specimen of tall grass found in this bog saved and under date of March 19, 1935 - identified by D. H. L. Mason as Poa scabrella - EHW March 21, 1935)
