ings. We awoke this morning and found ourselves a short distance from the steep banks of the Snake River, and bounded on either side by massive cliffs 150 to 200 feet high. Rock Wrens were singing from the talus slopes below the cliffs, and the young of Prairie Falcons could be heard squawking from a ledge somewhere on the cliff.

Ranch 11 miles west of King Hill and although no Citellus or Marmots were seen, we did collect a large lizard which looked somewhat like Crotaphytus but with a different arrangement of spots. We kept the specimen for identification. A lone Western Towager was seen out in the sage near the ranch evidently stopping here while migrating northward. Davis collected a Pacific Wighthawk near the river below the ranch. We stopped at Rupert for several hours, then continued toward the mountains which already seemed close by. We collected a pair of Citellus oreganus in the foot hills then climbed toward Mount Harrison above. We watched the transition from sage to Utah Jumper, then to Douglas Fir.
