Otelka 1943 June 13 2 mi SE Beggum, 1650 ft, Tehama Co., Calif. stream border. The other half were set on dryer, gentle slopes among scattered manzanita, scrub oak, and digger pine. The ground was covered in part with dried grass (largely Avena and Poa); otherwise it was bare. The loose brown soil was mixed with small pieces of a weathered shale-like rock that appears stratified on exposed slopes between layers of granite. One Peomopus trueri (only) was caught on bare soil manzanita near a dead shrub in the vicinity of scrub oak, digger pine, and manzanita, as described above. June 14. Hunted on the southwest slope again this morning, but to the east of yesterday's collecting site. I followed a roadway leading into the Bishop Ranch, which is located in the next valley to the south, but extends to the Beggum Road near our camp. The variety of habitats observed yesterday was again met today except that no black oaks were seen. Instead another species, probably Q. wilgenii, was found with Q. lobata and digger pine along a north-facing drain. 40 traps were placed on a south-west facing slope among scrub oak and Pedestoma spaced
