_Specimens examined._--Total, 3, distributed as follows: Los Angeles County: San Antonio Canyon, 2800 ft., 1; Palmer Canyon, 2100 ft., 1; 4 mi. N Claremont, 1800 ft., 1. Family URSIDAE =Ursus americanus californiensis= J. Miller Black Bear Eleven black bears were introduced into the San Gabriel Mountains "near Crystal Lake" in November 1933 from the Sierra Nevada (Burghduff, 1935:83). I do not know whether or not there have been subsequent introductions. There are still bears present in the higher parts of the mountains, especially north of the study area, where they seem to be maintaining their numbers. The grizzly bear that formerly occurred in the San Gabriel Mountains was exterminated there some years before the black bear was introduced. Family PROCYONIDAE =Bassariscus astutus octavus= Hall Ring-tailed Cat Large sections of the San Gabriel Mountains are uninhabited by this species, while locally, in the chaparral belt near water, ring-tails are common. Many reports of ring-tails were received from owners of cabins and homes who reside in the canyons at the Pacific base of the mountains. Because of the distinctive appearance of this animal it is likely that many of these reports were accurate. The reports testified to the presence of ring-tails in San Gabriel Canyon, Dalton Canyon, Palmer Canyon and San Antonio Canyon. Hall (1927:41) lists specimens from San Antonio Canyon. Kenneth Hill of Upland told me that ring-tailed cats often have been trapped above that town near citrus nurseries that are regularly irrigated. This species probably is not present on the desert slope of the range. The only specimen that I took was a female weighing one pound and fourteen ounces. It was trapped on March 24, 1951, among granite boulders, beneath scrub oak and bay trees, near the mouth of Icehouse Canyon, at 5500 feet elevation. =Procyon lotor psora= Gray Raccoon The raccoon was one of the most common carnivores in the San Gabriels and was found on both slopes of the range. Tracks were noted and one old male was trapped at the base of the Pacific slope foothills at 1900 feet elevation, and raccoons were captured at several localities from this point up to 5500 feet in San Antonio Canyon. They were noted on Blue Ridge at about 8000 feet elevation foraging around the camp grounds. On the desert slope they occurred down to the lower edge of the pinyon-juniper belt, for example near the mouth of Sheep Creek Canyon. Sign of raccoons was most often found near water; tracks, however, indicated that these animals, along with other carnivores, used fire roads for traveling through the chaparral. In a small draw one-half mile east of the mouth of Thompson Canyon two raccoons were trapped although the only water was a series of small, disconnected seepage pools beneath the valley oaks.
