canyons, at Palmers canyon and in other suitable localities. One 

 was taken as high as Kelly's cabin — on Ontario peak, among fallen 

 logs by a cold mountain stream. While setting trap in the run- 

 ways I more than once caught glimpses of them darting along the 

 aisles in the grass. 



Thomomys botta' ptillfscfHS. Rhoads. Southern Pocket Go- 

 pher. Abundant in the valley, often doing much damage in lawns 

 and orchards. 



Perodipiis agilis (igilis. (Gambel.) Gambel Kangaroo Rats. 

 Abundant from \'aliey to Transition zone. I found them abundant 

 at Brown's Flats where the evidences of their digging and their 

 holes are on every side. I have trapped them in brush country, 

 rocky areas, open brushless places, and at the mouth of ground 

 squirrel holes. 



Lepiis nilifoniiciis. (Gray.) Jack-Rabbit. Common in the 

 valley and to a certain extent in the foothills and higher. 



Sylvihigiis ciudiiboiii sanctidit'yi. (Miller.) San Diego Cotton- 

 tail. Abundant in the Lower Sonoran zone. Increasing each year 

 due to the protection afforded by game laws. Considerable damage 

 to young trees is done by cottontails and thev are a great pest to 

 the farmer. 



SyhUiigtis bdiliiiutii'i ciiicrd.ufiis. (Allen.) Ashy Brush Rabbit. 

 Fairly common in the brush. They are not swift runners and rely 

 on escaping by hiding behind clumps of brush, ihis is more t\pi- 

 cally an Upper Sonoran form. 



Felis oregoueusis orcgoiifiisis. ( Rafinesque.) Pacific Congar. 

 Numberless reports are always coming in of Mountain Lions and 

 as usual most of them prove to be unfounded. However authentic 

 records of these beasts are not lacking. I have personally inspected 

 a specimen shot in Cold Water Canyon not more than fi\e years 

 ago. Tradition has it that at one time a mountaineer was actually 

 beseiged for two days in the little cabin at Browns Flats. Lions 

 have been seen at Browns Plats, Cattle Canyon and the north of 

 leiegraph peak. Mountaineers tell me that they are a great deal 

 more common in the San (jabriel drainage. The specimen which 

 I saw was from one ol the trilnitarv canyons to the San Ciabrlel 

 river.
