Orr 1931 Brew Creek, 7000 ft. Nye Co., Nev. Sept. 23, 1931 Lift out the same trap line this morning. Around Cement River around and collected them. One set down in a swampy area likely to harbor shrews or Microtus contained a Lincoln Sparrow. All the rest were empty. No bats tonight. Set out about 1/2 dozen mouse traps baited with rolled oats at the very entrance to a number of large holes which were likely to be those of Dipodomys. Sept. 24, 1931 This a.m. traps contained 1 immature Peromyscus maniculatus and 1 Dipodomys. The Dipodomys was caught just as it was emerging from its burrow. The Manxaroo Rat from this region appear like the species levipes. However the country is entirely different from that in which levipes is usually found. It is tall sage with open meadow covered with juniper. The "clips" have been caught in the meadow and in small ditches along along
