_Lynx eremicus californicus._ (Mearns.) California Wild Cat. Common in the mountains and ranging over the valley. About once a year a specimen is brought in to be skinned or identified and great stories are told about them. One of the commonest fallacies is that there are two forms in the mountains, one a "Bob cat" with short tail and ear tufts, and the other a true "Link" or Lynx with longer tail and more prominent ear tufts. It is little wonder, however, that such a notion exists in view of the fact of the great range or variations found in these animals. As for actual records of captures. In the summer of 1911 one was shot in the brushy hillsides of Laguna Canyon (Orange Co.) and brought in to the Marine Laboratory. In the spring of 1912 a [F] was shot at the mouth of San Dimas canyon and brought to the college. In December 1914 a [F] in very worn pelage was shot while crossing the Santa Ana river near Prado Beach and brought to me to be skinned. Finally while trapping for foxes in Palmers canyon in March of 1916 I took a male. _Canis ochropus ochropus._ (Eschscholtz.) California Coyote. Common in the brush land above Claremont and in the foothills. The yapping bark is a very familiar cry to any who live near the outskirts of the town and may be heard nearly any evening. Although having camped numerous times in the mountains I have never heard Coyotes above the foothill region. _Urocyon cinereoargenteus californicus._ (Mearns.) California Gray Fox. Signs of foxes in the canyons and along mountain trails are always quite common. Foeces containing seeds of manzanita berries are familiar occurrences. They are fond of fruit and are readily trapped with such bait. In March 1916 three were caught one night at the same place in Live Oak canyon. _Procyon psora psora._ (Gray.) California Coon. Coons are fairly common in the larger canyons where there is an abundance of water. I have seen their tracks in Palmers, Cucamonga and San Antonio canyons. Three were trapped this winter (1916) just above Camp Baldy at an altitude of about 5400 feet. _Mephitis occidentalis holzneri._ (Mearns.) Southern California Striped Skunk. Not very common in this region, found mostly in the Upper Sonoran zone in wooded districts.
