Lee Arnold 1937 Peromyscus crinitus near Smith Creek Cave, 6,300 ft., Mt. Moriah, White Pine Co., Nevada June 4, Out of 100 traps set on the bottom land of Smith Creek canyon I caught only one P. crinitus. This was an adult ♀. It is interesting to compare this with the seven Peromyscus maniculatus June 7, Out of 30 mouse traps set on the sidehill west of camp I caught 1 adult ♂ Peromyscus crinitus while out of 12 traps set in the flat directly below this spot I caught one Imm. ♀. June 9, Out of 42 traps in the same type of habitat as that of June 7 only SE of camp on the side hill I caught 2 P. crinitus: 1 Adult ♀ and 1 Imm ♂. In this habitat the Peromyscus maniculatus and crinitus seem to be found in about equal abundance. The habitat is characterized by scattered boulders, medium sized jagged rocks, Artemisia, juniper and bunch grass. June 11, 2 mi. W Smith Creek Cave, 6,300 ft., Mt. Moriah, White Pine Co., Nevada Out of 45 traps set in among the boulders and ledges north of camp I caught 5 adults. The habitat was: Steep hillside; large flake-like boulders with frequent outcropping showing the strata and offering ledges
