262. Vireo bellii pusillus (Coues). 



Least Yireo. — Rare at the Cape region according to Mr. 

 Belding. Mr. Antlionj found it common in willow thickets 

 on tlie northwest coast up to 3,000 feet altitude. Nesting 

 from 500 to 2,500 feet altitude. I obtained specimens on 

 Santa Margarita Island in winter, and found them in May 

 at San Fernando; at Comondu in March; at San Benito in 

 April, and at El Rosario, May 21, 1889. 



263. Vireo vicinior Cones. 



Gray Yireo. — Not many were seen in any part of Lower 

 California by Mr. Belding, who noted them from south of 

 Campo, at an altitude of 3,000 feet in May, 1884; near San 

 Rafael in May, 1885, and the mountains east of Ensenada 

 in April, 1887. 



264. Helminthophila ruficapilla gutturalis Eidgw. 

 Calaveras Warbler. —Mr. Belding reports the bird as a 



rare migrant. He has seen it only in spring at Tia Juana, 

 a town on the boundary line. 



265. Helminthophila celata (Say). 



Orange-crowned Warbler. — A single specimen was col- 

 lected by Mr. Belding at the Cape region in January, 1882. 



266. Helminthophila celata lutescens Eidgw. 



LuTESCENT Warbler. — Common at the Cape region 

 according to Mr. Belding, who has occasionally seen it 

 between the boundary line and San Pedro Martir. Other 

 observers do not mention having seen it in Lower California. 

 On Santa Margarita Island I found it common in January, 

 1888, and at Comondu in March. In San Benito canon I 

 shot a male April 10, 1889, and took a female at El Rosario 

 May 21, 1889. One of the Santa Margarita Island birds 

 which Mr. Ridgway has examined is quite different from the 

 others of the series and may, he remarks, belong to a local 

 race. My visit to the island this year was made too late to 

 find many of the small land species obtained the previous 

 year, and no additional specimens were taken.
