Thaeler 1959 Species Account Thomomys tawrendi selectus (p.1) Apr.3 3.4 mi. N., 2.6 mi. W. Doyle, 4250 +/- ft. Lassen Co., Calif. This morning while driving along U.S. 395 north of Doyle I noted several large gopher mounds on the W side of the road, just beyond a sign warning (North) motorists of presence of livestock. I set out three sets of gopher traps, two in track from the road a few yards and one on the shoulder. The tunnels of these animals are very large. When they are straight I could put my entire forearm into one. This evening I took one gopher from the set on the shoulder of the road. This area is on a hill side, facing S W and overlooking the Long Valley Creek. It is one hundred feet or so above the stream. The vegetation is open with scattered clumps of brushers. Some at least are sage. The intervening areas are grass covered. The soil is sandy, easily to dig in, reddish-yellow in color. The distance from Doyle was figured from a point where U.S. 395 crosses the seed line between sect. 8 and 17 of T. 25 N., R. 17. E. This point was also used for figuring the T. monticola locality on the Rawland Ranch. I used the Doyle, Calif. 15' quad, 1954 of the U.S.G.S. Apr.5. 0.3 mi. S., 3.0 mi. W Herley, 4020 +/- ft., Lassen Co., Calif. Last evening I set a couple of gopher sets on the south shoulder of the main E-W road into Herley from U.S. 395 at this point. This area is gently sloping
