T. Rodgers -- 1942. 203D Itinerary Sacramento Valley trip, Mar. 6, 7, 8, 9. fine talus that it would not furnish cover for skinks. We turned west again, and at Arbuckle, we turned south to search the floor of the valley for skinks. We spent the rest of the day looking under lumber and debris around abandoned and occupied ranch yards. We found an abundance of apparently suitable habitat, all the associated animals, well-drained porous soil, but no skinks. We feel fairly safe in assuming that skiltonianus has not extended its range onto the floor of the valley in the southern part of the western side of the Sacramento Valley. We crossed the Sacramento River at Rio Vista, the San Joaquin River at the Antioch Bridge, drove southeast through Brentwood and up Marsh Creek. We made a stop 5 mi. SE Clayton, where Dalquest collected a Diadophis and a Lampropeltis and Cook collected a Pituophis. We arrived in Berkeley about 7:00 p.m. Catalog of specimens collected on the trip, extcept about 10 or 15 collected at the first 3 localities by Cook, and about 5 collected at several localities by Dalquest, follows on pp. 204-216.
