Lilleland 1933 28 Itinerary July 20 The ground sloped gently to E. Occasional ridges and washes broke the otherwise uniform topography. Vegetation sparse and low growing. Bush that is most widely distributed has terminal spicules much like some cacti - tho bush itself in shape is like saye brush. Understand that bush is an Atriplex (?) Soil varied consider- ably. Some places it would be very sandy and fine - other places gravelly and in still others clayey and alkaline. Caught 8 Perognathus nevadensis, 6 Microdipo- dops, 4 Dipodomys m. levipes and 1 Onychomys leucogaster brevicaudus. Total number of traps set was 64. Caught the Microdipodops in the sandier lighter soil. The Dipodomys were scattered as were also the Perognathus nevadensis. The single Onychomys was caught 25 ft from the road in a clayey flat. When setting the traps I had run out of cotton, and wishing to set the full complement and yet not jeopardize my chance of finding the trap, I had set it out away from bushes. Caught a leopard lizard Crotophytes in, which was watching a live P. nevadensis. Also came upon a Dipodomys m. levipes sitting by a trap, rolled like a ball. Grabbed it and found that it had been caught
