other five at San Jose del Rancho in December. Mr. Belding's mention of 

 difficilis as " rare " may refer partly or wholly to the next species, which, of 

 coarse, had not been separated at the time Mr. Belding's papers were written. 

 It is not probable that E. difficilis breeds anywhere in the Cape Region, 

 although it may possibly do so in the extreme northern portions of the Penin- 

 sula. According to Mr. Bryant, it has been met with by Mr. Anthony at 

 Valladares, during the autumnal migration, and by Mr. Belding in wo ided 

 canons north of San Pedro Martir in May. It is abundant in summer through- 

 out niost of California and regularly ranges northward into British Columbia, 

 wliile a single specimen has been taken at Sitka, Alaska.^ In winter, it is said 

 to go as far southward as Costa Rica.
