O. Memmler 12 Itinerary May 26, Russian Gulch State Park, Mendocino Co., Calif. 200' elev. Blackberry and Wild Rose, traps were spaced about every 20-30 paces. There were 9 traps sprung + without animal. We caught 1 ♀ Sorex pacificus, 2 ♂ Peromyscus maniculatus, 1 ♀ Peromyscus maniculatus and 1 ♀ Sorex vagrans. In addition 4 Rat traps were set in the vicinity of Wood rats nests. One not in sight of any definite house but in the typical habitat was found with a few bits of fur and the intestinal tract were next to the trap which was sprung. Another trap set about 10 paces from a house had a ♀ adult. One set 20 paces from the proper contained an immature ♀. A fourth trap was unsprung and not near a nest but only in the correct habitat. Trees in the habitat were Grand fir, Douglas fir and Law Oak. The ground is allured out with dead branches. It is very dark in the habitat since the trees are large and cast much shade. There is little moss on the ground
