season- The character of the ground at San Ramon, where a 

 few were undoubtedly nesting, was a broad sand beach, covered 

 with drift-wood, flanked by a few sand dunes, back of which was 

 a series of small lagoons of brackish water, thickly grown to 

 tules. The eggs of this species which are frequently offered to 

 the public by local collectors of Southern California have, so far 

 as my observations have gone, always been taken from the nests 

 of A. beldingi. 



Zonotrichia Icucophrys. White-crowned Sparrow. 



Zonotrichia leucophrys intermedia. INTERMEDIATE Sparrow. 



Zonotrichia leucophrys ganibeli. Gambel's Sparrow. All 

 of the white crowns are abundant about the base of San Pedro 

 during the winter months, and a few are to be seen in the pines 

 during migrations. But few specimens were taken and the 

 comparative abundance of the different species was not deter- 

 mined. 



Zonotrichia coronata. Golden- CROWNED Sparrow. Quite 

 common during the migrations with the white crowns but seems 

 to winter farther south than the bulk of these species. All of 

 the coronata taken in April were moulting and unfit for specimens. 



Spizella socialis arizoncs. WESTERN Chipping Sparrow. 

 Very abundant about the base of the mountain and resident; one 

 was shot at 7000 feet elevation May 10. 



Spizella atrigidaris. Black- chinned Sparrow. Rather 

 common in the hills from the coast to the base of the mountain. 

 I have no specimens from the pine belt, but am sure that its song 

 was heard in May, 1887, at 10,000 feet elevation. 



Junco hyemalis tlmrberi. ThurbEr's Junco. It is quite 

 probable that all of the Lower California records of 07-egonics 

 belong to the present species. I found them about the base of 

 San Pedro in winter with toicnsendi^ and met with them in the 

 Burro Cailon north of Ensenada April 23, the past season. 



Jicnco tozvnsendi. Townsend's Junco. Very abundant 

 throughout the pine region of San Pedro, only reaching the 

 lower elevations in winter. The past season the j uncos were 

 found building upon our arrival in the pines, May 5, but no
