Hoffmeister 1942 Sorex palustris June 10 3mi S & 8mi W Big Line, 7700ft, Inyo Co, Calif. Last evening when crossing Big Line Creek at about 7:15 p.m, and at least 1/2 hour before complete darkness, I thought I saw a water shrew in the creek. It disappeared so rapidly downstream that it may have only been a piece of floating debris, but the coloration and proportions suggested a shrew. It was near the shore. This morning I caught 2 water shrews downstream about 150 feet from the place I thought I saw the shrew swimming in the stream last night. One palustris was caught 6 inches from the water's edge in a thicket of dead willow branches. The other was caught in a marshy, grassy spot about 15 feet from the creek proper. One other shrew, Sorex obscurus?, was trapped during the night in the same habitat as the latter S. palustris was caught in.
