Lee Amald 1937 Ammospermophilus leucurus Mouth of Fox Canyon, 4,200ft, 7 1/2 mi. S Pahrum Pk., Washoe Co., Nevada. June 1 Adult ♀ shot at edge of wash. north of Pyramid Lake. It was sitting in the top branches of a bush watching me as I approached. When I shot it fell to the ground. I saw what I thought to be it run down a hole at the base of the bush. Upon running to the bush I saw still another form run down the hole. These were evidently young of the one I shot for the adult ♀ with enlarged mammary glands lay dead on the ground. June 5, Adult ♀ shot 1 mile W Smith Creek Cave, 6,000ft., Mt. Thorizh, White Pine Co., Nev. It was sitting upon a large boulder at the crest of a hill — watching my actions. The ground was coarse and rocky while the shrubbery was sparse - mostly artemisia tridentata and "bunchgrass" with scattered cactus. June 7 An adult ♂ shot within 50 feet of spot where ♀ was shot on June 5, 1937. These two seem to be the only ones living this far from the mouth of the canyon. Henry Creek, mi.
