Moore 1931, [illegible] 50 to 30 ft R.N.E., T.I.N. Providence Ints., Joshua Tree Desert, San Bernardino Co., California May 27, 1931 Although insects were extremely abundant, no bats or night hawks were seen during the course of the evening. As we made camp at 4:30 swarms of minute moths hovered about us and were quite annoying as they possessed a bite or sting that set up quite an irritation, especially on the underarm. Quail were heard calling in a wash bottom as the sun set. Redlands, &1700 ft. San Bernardino Co. California. May 26, 1931. We proceeded on to Redlands from Evans Well via Fenner, Ambrey and Victorville.—Ten live mouse traps set at Evans Well last night produced four Peromyscus m. sonoriensis, and one juvenile Notona desertorum, also a juvenile Peromyscus b. rowleyi. I attempted to bring two of the Peromyscus m. sonoriensis back alive in a well ventilated box, but as the temperature stood at 106° at Ambrey they were not able to withstand the heat and died before I reached home. The air was relatively cool where they were trapped and the soil was moist six inches under the surface. On a grassy slope near Evans Well I found a large burrow with soil piled up at its entrance that appeared as if a ground squirrel had been working there. A Phrynosoma was basking in the sun.
