W.B. Davis 1935. 2 mi. S Payetto, between Payetto and Snake River), Payetto Co., Idaho. June 7. Aldrich caught one Perognathus parvus. The morning was spent in making up skins. About noon I walked to the other side of Snake River, crossing by means of the C. & L. railroad bridge, and hunted for ground squirrels. I found and killed four Citellus leurodon. They were in a cultivated area, having their burrows in the clay-like soil along the fences and the larger irrigation ditches). Here the cover was either tall weeds, mostly Pepper Grass, and Artemisia tridentata. There was a large area of tall Atriplex in an area adjacent in which I heard the single note whistle being given. I hunted only along the fence and an empty irrigation ditch, and actually hunted no longer than 30 minutes. The burrows lacked the typical mounds) as we found them near Murphy, but there were usually groups of burrow entrances clumped together in a small area. The two kinds of squirrels - Abahouensis and leurodon
