2 mi. S Melba, Canyon Co., Idaho, May 28, Creek Valley there was only the little brown mountain gopher (quadrotus). He said that along the river north of Reynolds Creek that the big blue (townsendii) gopher was the common one. Mr. Adams was alert, though apparently inclined to laziness, and his statements concerning the mammals are, I believe quite correct. He said, also, that there were few skunk, but many coyotes and just a few badgers in the valley. We also stopped just south of the river and inquired about Thomop and Citellus. One rancher whose name I didn't get said he had a few gophers, but that he, like his neighbors, had them pretty well under control. He said he had seen no leurodon but that an animal whose description fitted Ammospermophilus perfectly was to be found in the 'grease wood' area. We didn't stop to investigate because it was late and we wanted to make camp and set out traps yet before dark. Twining and Aldrich each set out 30 traps among the rocks of the cinder butte. I set none, but cooled supper
