feet, three (nos. 2305, 2306, 7796) ; Snow Creek, 1500 feet, two 

 (nos. 2307, 8863). In February, 1912, a skin of one was seen 

 at Palm Springs, eaughl recently at the base of the foothills near 

 there. It will be observed that these stations are chiefly within 

 the Upper Sonoran zone, though the species ranges ;i little above 

 and a little below. This is wholly in accord with the preferences 

 of Mephitis elsewhere iii southern California. 



Stomach examination showed in one ease bones and fur of a 

 Microtus; in another case berries and leaves of manzanita to- 

 gether with bones and fur of an unrecognizable species of small 

 mammal; in a third ease the stomach was filled to distention 

 with "Jerusalem" crickets (Stenopelmatus) , while there were 

 fragments of legs and other hard parts of these insects in the 

 feces. A remarkably varied diet is thus indicated. 



Spilogale phenax phenax ('. II. Merriam 

 California Spotted Skunk 

 Specimens secured as follows: adult male. mi. 18!)S. Ken- 

 worthy. 4500 feet, -May 24; young male, no. 1907, Carrizo Creek, 

 3000 feci. June 22; adult male. do. 2302, Cabezon, 1700 feet. 

 May 11. These localities range from high Upper Sonoran down 

 well into Lower Sonoran — the usual zonal range of the species 

 elsewhere in southern California. 



Mustela arizonensis ( Mearns) 

 Mountain Weasel 

 A sine'lc specimen was captured in Tahquitz Valley. 8000 

 feet, July 23. It was caught in a gopher trap, of the box pattern, 

 open at one end. with heavy spring released merely by the 

 animal's pushing against the trigger. This trap had been set 

 in the meadow sod in the usual way for gophers, and the fact 

 that it produced a weasel gives insight into the forage methods 

 of the carnivore. One other instance of the presence of weasels 

 in the region came to our attention: A skin of one was seen in 

 the possession of a cattle man at Fuller's Mill, 5900 feet. July 2; 

 it had been caught in the near vicinity a few days previously.
