having been taken. Four in Cohuilla Valley and one at Banning. 

 They are abundant Winter residents. 



75. Spizella socialis Arizona Coues. ( Western Chip- 

 ping Sparrow). A $ shot in Cohuilla Valley April 1st answers 

 Dr. Coue's description of this variety, but I doubt if the variety is 

 tenable. Specimens from nearer the coast show all gradations of 

 the crown patch. One was taken at Banning and another at Yuma. 

 They seem to be uncommon in these localities while I found thern 

 rather common at Bear Valley in the open parts of the pine timber. 

 A young male was taken here June nth, which proves that they 

 breed in this locality. 



76. Spizella breweri Cass. {Brewer's Sparrow). This 

 was a common bird in all the localities visited except Yuma, where 

 it probably occurs in Winter as well as during the migrations. They 

 evidently breed in Bear Valley. 



77. Spizella atrigularis (Cab.). [Black- chinned Spar- 

 row). This is not a common bird in the Cohuilla Valley, at least at 

 this time of the year. They were found at all the localities visited 

 with the exception of Yuma, where they probably occur as migrants. 

 A $ shot April 30th at San Bernardino was laying, had probably 

 dropped one egg as the ovary contained three well developed ova. 

 They were rather common in the lower part of Cajon Pass. 



78. Junco hvemalisoregonus (Towns.). {Oregon Junco). 

 Not uncommon in Bear Valley where they breed. 



79. Amphispiza biline ata (Cass.). {Black-throated Spar- 

 row.) Appears to be common in Cohuilla Valley where several 

 were taken between April 5th and 15th. A pair of the birds, 

 together with a nest containing young, was seen on the Mojave 

 River June 5th. 



80. Amphispiza belli (Cass.). {BeWs Sparrow). Not un- 

 common in the Mojave Desert. One was taken in Cajon Pass June 

 4th and two were observed in Bear Valley. 



81. Melospiza fasciata fallax (Baird). {Desert Song 

 Sparrow). Observed only at Yuma which is the only locality 

 visited in which it is found. 



S2. Melospiza fasciata heermanni (Baird.). Hecrtnanii's 

 Song Sparrow). This species is not uncommon in Cohuilla Valley 

 and near San Bernardino. At Yuma they are replaced by variety 

 fallax.
