ance in the latter region as far east as Cabezon. In the moun- 

 tains proper it was noted in fair numbers at Kenworthy in May 

 and June, and, the highest record station, at Schain's Ranch, 

 4900 feet, in May. 



Eighteen specimens were taken: Cabezon, four (nos. 1622- 

 1624, 2132), Banning, two (nos. 2036, 2037), Snow Creek, one 

 (no. 2167), and Schain's Ranch, eleven (nos. 1815-1825). 



Zonotrichia leucophrys leucophrys (Forster) 

 White-crowned Sparrow 



Observed migrating in fair abundance during May, at Cab- 

 ezon, on the desert side of the range. Seen elsewhere only at 

 Kenworthy, where a single bird was taken May 24. In southern 

 California this species is largely confined to the desert regions 

 east of the mountains, when' it is a fairly common migrant. In 

 the Pacific slope valleys it is of decidedly rare occurrence. 



Six specimens were taken by the expedition, five at Cabezon 

 (nos. 1617-1621). and one at Kenworthy (no. 2355). 



Spizella passerina arizonae Cones 

 Western Chipping Sparrow 



An abundant species in the higher parts of the mountains. 

 Seen commonly from the altitude of Schain's Ranch (4900 feet) 

 and Strawberry Valley (6000 feet) upward on San Jacinto 

 Mountain, and from Garnet Queen Mine (6000 feet) upward on 

 Santa Rosa Mountain. Not seen in Hemet Valley until after 

 the termination of the nesting season. Early in August flocks 

 composed largely of juvenals were noted in weed-grown fields 

 about Hemet Lake. The middle of August they were conspicu- 

 ously abundant on Thomas Mountain. 



Though not encountered in the lower parts of the mountains 

 proper, the species was noted, rather singularly, at one low zone 

 station at the northern base of the range. In Banning (2300 feet) 

 chipping sparrows were seen at various times during the second 

 week in June, in orchards and gardens in the town, and it accord-
