R. Zweifel Feb. 22, 1939. Little Panache Creek, Fresno Co., Calif. In April, 1939, Dr. A. H. Miller collected Two adult Rana boylii in this creek, 2 mi. N Mary Hot Springs. At the present time, The streambed at this point is absolutely dry. Downstream about two miles the stream appears to be permanent. There is a thick growth of willows bordering the stream, giving way at places to Baccharis vinnosa and cattails. This area does not have the open sandy stream banks usually characteristic of streams inhabited by Rana boylii, nor were any frogs but Hyla regilla found. At the reported boylii locality upstream there were no trees, the only conspicuous vegetation being Atriplex and grass grazed short by the sheep. Probably after exceptionally wet winters, populations of frogs may temporarily become established here in the semi-desert, but the habitat is certainly marginal. There are three or four small creeks in the drainage of Little Panache Creek which probably have Rana boylii in their headwaters. Uta stansburiana was the only reptile seen. These were common.
