Coluber constrictor 20 Aug Haskell Ranch, 10 mi. S. Marysville, Yuba Co., Calif. (A.S. Leopold Ranch). Caught a juvenile racer under a wood plank in a cow field adjacent to a marsh when Pituophis sirtalis was taken (q.v.). The pasture is covered mostly by low grass - 6-7" tall, with a little Bromus and Centauria, the latter in drier spots. Most of the ground is damp, and a little is flooded. The field is separated into several sections by dikes about 12" high running irregularly thru the area, and most of the water is by the dykes. The plank was in the damp (but not wet) center of a low area. The snake was coiled on the matted vegetation beneath the wood, which was about 2 x 3 feet in size, 1/8" thick, in the open (though now in the shade of a fence) sun. When found about 7:30 the snake was inactive, though readily capable of motion. It made no attempt to bite.
