E.V. Miller 1940 36. General Account, among small dunes of light brown sand. These dunes were fairly thickly covered with brush, weeds, etc. In the evening I set out 47 live traps for mice around the edge of a planted field and a hay field next to brush. June 4. Took nothing in my live traps and in the others 1 & Dipodomys mericanus, 2 & 1 & Dipodomys ordii. In the afternoon we drove on to the White Sands National Monument, Otero Co., New Mexico. The museum at this place was under construction. The officers present were exceedingly helpful and allowed us to camp and trap in the sands. We camped 4 mi. N W of the Museum. I set out 47 live traps and 67 M. specials for mice. June 5 Took one Peromyscus maniculatus in my live traps and one Dipodomys mericanus, 2 Dipodomys ordii and one Chaetodipus torridus in my wooden traps. On the afternoon of June 4 we picked up a & Badger along the road, 14 mi. NW Carlsbad, Eddy Co., New Mexico. June 7 We camped 17 mi. N W Yndio, Riverside Co, Calif. After dark I set out 47 live traps for mice among sparse brush growing on sand dunes of gray-white sand. June 8 Took nothing in my traps, possibly because of lack of bait. Benson got 2 species of pocket mice, a Dipodomys and a Vimus.
