Lee Arnold 1937 Thomomys bottae 1/2 mi. W Smith Creek Cave, 6,000 ft, Mt. Moriah, White Pine Co., Nevada June 6, Adult ♀ caught on flat area at south bank of creek. The ground where caught was harsh with many small (walnut sized) jogged rocks. The trap was set at the base of a prickly pear cactus—These were apparently roots of which what the mammal was eating.

Moriah, White Pine Co., Nevada. These were in the same type of habitat as the ♀ of June 3—(Smith Creek). In both cases cactus seemed to be part of the diet. In one hole I found particles of grass while in
