R. Zimpe Sept. 19, 1957 Kern Co., California The object of today's trip was to collect some Rana boylii in the Kern River. Our first stop was at Hobe Hot Springs. The mountainsides at this locality are covered with a sparse growth of digger pines. By the river, cottonwood and sycamore are dominant. Rana calaverina was common, but no yellow-legged frog could be found. Two striped racers were found by the stream. A large Hermodice multicaudata found in the stream may have just escaped from one of the racers, as the lizard's tail had been freshly lost and the snake bore tooth marks on its neck. Another stop was made at the point where the Kern River crosses the road just north of Isabella. Here the river passes through a wide, arid valley. Again only R. calaverina could be found. Hyla regilla was also present. We next drove back up the South Fork to Onyx. Here the stream is about 12' wide and deeply shaded by cottonwoods. Hyla regilla was the only frog found here. A small Crepidophora tigris which looks most like the desert form was collected by the stream.
