Hullion 1949 Cotomias amoenus -2- Sept 10 Red Mtn, 5300 ft., 14 mi. S Hayfork Trinity Co. Calif. tolerable. As soon as I drop into a mature forest area down off the ridge they drop out, or in a pure [illegible] chaparral they also drop out. It is the edge between these two elements, or where each is only partly developed that they are found. However, as I worked on up the barren ridges of South Dubabella Mtn., and the forest and chaparral became sparse, and rock more dominant, these chipmunks completely replaced the other species and in some places became quite abundant.
