_Spilogale phenax phenax._ (C. H. Merriam.) California Spotted Skunk. Very common in valley, foothills and up to 6,000 feet in the mountains. They are fearless little creatures and will readily enter cabins in the mountains and keep the occupant awake by rattling pots and pans while scrambling around in search of food, needless to say creating an awkward situation for the host. They have been known to take up their abode underneath houses in Claremont and take the liberty of scampering around the parlor floor without regard to the presence of human beings. This was a common occurrence in a certain family I have in mind and on such occasions the unwelcome guest was gently ushered to the door without hurting its feelings and peace of mind restored to the household. They are the easiest of all animals to trap and made considerable trouble and embarrassment for me by continually blundering into traps of mine set for other game. I have found these little creatures as high as 6,000 feet in the canyons. _Mustela xanthogenys xanthogenys._ (Gray.) California Weasel. I had always been interested in weasels as to their occurrence and until this year had taken only one in town with a record of only two or three seen along the railroad track. Then in one week four weasels were given me and a record of seven others obtained, all these are from nearby orange groves and from below town along the railroad track where for a long time I have known they occurred. _Scapanus latimanus occultus._ (Grinnell and Swartz.) Southern California Mole. Moles are occasionally caught in orchards and lawns and the characteristic workings are familiar sights in the mountains up to 8,000 feet. Our specimens were all from the valley. _Antrozous pallidus pacificus._ (Merriam.) Pacific Pale Bat. I have taken several of these bats from behind pictures and in the attics of some of the college buildings. I do not know their relative abundance or distribution but they are certainly common on the campus in spring and summer. _Myotis evotis._ (Allen.) Long-eared Bat. This form also occurs in the college buildings and I believe to a certain extent in the mountains.
