2 mi. W Smith Creek Cave, 6,300 ft. Mt Thorman, White Pine Co., Nevada Lee Arnold 1937 Itinerary June 11, Last night we shot several bats. Most of them were small dark brown Myotis (sp?). Fitch collected one Myotis evotis. I set 45 traps along the ledges of the cliffs on the north side of the canyon. I caught: 5 Peromyscus crinitus 2♂;3♀ 4 Neotoma lepida 2♂;2♀ It was interesting to me to find that Johnson and Fitch who were trapping on the south side of the canyon caught many Peromyscus maniculatus but no Peromyscus crinitus while I caught no Peromyscus maniculatus and several Peromyscus crinitus. June 12, Last night we again shot at bats this time we were not so successful as previously. We got one ♀ Myotis. Inasmuch as we are breaking camp today I left my traps in the same place they were set yesterday. I caught: 6 Neotoma lepida 1Ad.♂;3 Imm♂;2Imm.♀ 4 Peromyscus crinitus 2Imm.♂;2imm♀ 1 Perognathus ♀ It was interesting to note that I caught only immature crinitus in the same trepline that I caught only adults in yesterday. Another point of interest is that I caught two imm. crinitus in the same rat trap. The Perognathus is probably the same one
