T. Rodgers -- 1942 Itinerary Sacramento Valley trip, Mar. 6, 7, 8, 9. were 9 mi. out the road, elev. 300 feet, we had not yet reached the blue oaks. At 12 mi. NE, we were in blue-oak country. Northeast of Smartsville, we stopped several places and found many rocks to turn over, but found no skinks, very few Sceloporus and noted very few centipedes, millipedes and other invertebrates that had been so common in places where skinks were found. The ground was a red soil that had formed by weathering of the basalt rocks. Although the country is high and well drained, conditions under most of the rocks were as barren as if the country had been flooded. At 5 mi. SW Bridgeport, in such country as this, a skink was collected by Sherburne Cook. It was found about 1 foot under the ground, under a rock. At 4 mi. SSW French Corral the soil is lighter and not red. The two skinks collected there (one by Dalquest and one by Rodgers) were found under rocks that had been piled about two deep near the base of a fence. On the north side of the Yuba River, we collected on a hillside about 200 yds.NW of the bridge on highway 20. In about 40 minutes, 4 of us together had about 10 skinks. These were obviously skiltonianus since some were heavy-headed obviously mature individuals, yet much smaller than mature gilberti, and with sharply defined color pattern and blue tail. They were more active than gilberti found earlier in the day and on the day before. On the north side of Marysville Buttes, we camped about 1/2 mile up the canyon from the ranch
