June, Strawberry Valley and Fuller's Mill in July, and at Hemet 

 Lake during the first two weeks in August. One or two unmis- 

 takable horned owl feathers were picked up on June 15, in a 

 dense tangle of shrubbery at the mouth of Murray Canon, just 

 above the floor of the desert. 



Speotyto cunicularia hypogaea (Bonaparte) 

 Burrowing ( )\vl 



A eommoD species in the lowlands on the Pacific side of the 

 mountains, and in San Gorgonio Pass to the north, but appar- 

 ently very rare or entirely absent on the desert side of the range, 

 and not encountered by us higher than the very base of the 

 mountains. It is abundant on the extensive grain fields of San 

 Gorgonio Pass, as at Banning, where it was observed daily; 

 beyond thai point, where deserl brush replaces the cultivated 

 fields, it becomes more rare, though seen as far as Cabezon. 



On the west side of the range, a1 Vallevista, several were 

 seen on the stubble fields or near the edge of the adjoining brush 

 land. It is an abundanl species farther ou1 on the extensive 

 plains forming the San Jacinto Valley. 



Pour specimens were preserved, two adult males, one from 

 Cabezon, May 23 (no. 2129 . and one from Banning, dime 12 

 (no. 2053 . and two immature females from Vallevista, Septem- 

 ber 2 and 1 (nos. 3092, 3093 . The two latter are in fresh fall 

 plumage. 



Geococcyx calif ornianus (Lesson 

 Road-runner 



Observed at hut one point within the mountains, at Ken- 

 worthy (altitude 4500 feel . where, on May 27 and 28, one was 

 noted "singing" near the base of the hills. It is not probable 

 that the species ranges to a much higher altitude in these moun- 

 tains. On the desert slope of the Santa Rosa .Mountains, the hist 

 week in May, and about the middle of dune, single birds were 

 seen from time to time. They were encountered at Cabezon in 

 May, at Whitewater in June, and nt Vallevista in September. 



One specimen was preserved, a half-grown juvenal taken at 

 "Whitewater on dune 5 no. 2072).
