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 botlif pullesceus. Rhoads. Southern Pocket Go- 

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

 and orchards. 



Perodipus agilis agilis. (Gambel.) Gambel Kangaroo Rats. 

 Abundant from valley to Transition zone. I found them abundant 

 at Brown's Plats 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. 



Lepus calif or metis. (Gray.) Jack-Rabbit. Common in the 

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



SylvUiigus aiiditboni satntidifgi. (Miller.) San Diego Cotton- 

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

 due to the protection afforded by game laws. Consiclerable damage 

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

 the farmer. 



Sylvilcigiis hiirliiiuiiii cinfnisceiis. (Allen.) Ashy Brush Rabbit. 

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

 on escaping by hiding behind clumps of brush. This is more typi- 

 cally an Upper Sonoran form. 



Felis oreyonensis orcyoiwiisis. ( Ralinesque.) Pacific Cougar. 

 Numberless reports are always coming in of Mountain Lions and 

 as usual most of them prove to be unfounded. Howe\er authentic 

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

 a specimen shot in Cold Water Canyon not more than five 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 Flats, Cattle Canyon and the north of 

 Telegraph peak. Mountaineers tell mc that they are a great deal 

 more common in the San Gabriel drainage. The specimen which 

 I saw was from one of the tributary canyons to the San (iabriel 

 river.
