Hooper Aplodontia rufa 3 mi. W Drurness, Marin Co., Calif. June 25, 1938 Feathers and I located the colony reported by Taylor, Camp, Ferris et al when they were here earlier (1912?). It is on the ocean drainage side of the hill over which the Pt. Reyes highway passes exactly 1 mi. by my speedometer by road from the Caretski's house at the crest of the hill. The ridge on which they are found faces SE and is densely clothed with chaparral, contrasting markedly with the open grassland and semi-open Bishop pine forest higher up on the ridge and less marked with the Ceanothus-studded opposite slope. Vegetation immediately about the dens: blackberry, baccharis, wild rose, thimbleberry, salmon berry, poison oak, sword fern, brockeh [illegible], monkey flower. I see top of the hill and the opposite slopes are more exposed. The burrows are 6 or 8 in. in diameter with loose dirt before them and open into the hillside generally under a dense sword fern clump. One burrow may open not over 1 ft above a lower one. Feathers took 1 young animal in #1 jump trap. We took this to camp &
