Lee Amadell 1937 Myotis (sp.) Warm Spring, 4,000 ft., 9 mi. E Amedee, Lassen Co, Calif. May 27, Single adult ? shot over alfalfa field - others seen - probably Myotis. Mouth of Smith Creek Canyon, 5,400 ft., T Mt. Moriah, White Pine Co., Nevada. June 10, Two, one adult ? and one adult & shot over open space next to creek at mouth of canyon. Most of the bats seen were flying down the canyon end out on to the desert. I imagine that they roost in the large caves in the side walls of the canyon and forage over the vast open desert. For several nights we have observed them flying eastward past our camp in the canyon. 2 mi. W Smith Creek Cave, 6,300 ft., T Mt. Moriah, White Pine Co., Nevada June 11, I shot one ? flying about the tops of the willows around our camp. June 12, Shot single ? over camp. Weather colder than night before. There did not seem to be as many bats flying about. June 13, Two adult ? shot. June 14, Four Myotis (sp.?) and one Myotis evotis shot flying over and among the willow trees about camp. All of these were ? bats. The Myotis evotis and the of the Myotis (sp.?) had well developed single embryos!
