Lee Arnold 1937 Itinerary June 10, but was unable to get a shot at any of them. At a point about 1 1/2 mi. E Smith Creek Cave we stopped to shoot bats. I shot two Myotis, the species of which we are not as yet sure of. In my traps this morning I caught; Dipodomys microps 9 ♀ - 1 ♂ Peromyscus maniculatus 3 ♂ - 1 ♀ Neotoma lepida — 2 ♂ Perognathus longimembris 1 ♂. In comparing my Dipodomys with those caught by Fitch and Johnson I have found that there are more ♀ animals caught than males. This could be due to several causes but as yet we do not know the actual cause. In as much as June we are going to move camp today I am going to take this opportunity to sum up my opinions of this area. The birds seen near here (3 mi. radius) are: Say Phoebe (nest under ledge in camp) Canyon Wren Prairie Falcon White-throated Swift Pian Jay (1 ad. ♀ & 1 imm. ♂ shot) Warbling Vario Reven
