Bartholomew 1941 Dipodomys deserti. July 28 13 mi. N Goldfield, 5100 ft., Esmeralda co., Nevada. I set out 50 mouse traps at 20 step intervals on a level sandy area covered with hopsage (?) and pebbles up to three inches in diameter. I caught about a dozen P. longimembrio, a couple D. merriops and one D. deserti (immature). None of the other members of the party who set out a total of 200 traps caught any of this species. About 1/2 miles from the spot where I set out my traps, in the bottom of the sinka there was an area of fine sand. This immature animal may have wandered out from there for the pebbles made the site atypical for Dipodomys deserti.
