194 CALIFORNIA ACADEMY OF SCIENCES. 



British Columbia. John Fannin. Common summer 

 resident. March 20, 1885, only a few seen this year. 



Henshaw, 1879. Present along much of the eastern 

 slope. 



Hoffman. I noticed these birds along the banks of 

 the Humboldt River, north of Battle Mountain, during 

 the last days of May. 



Ridgway. Next to the cliff and white-bellied swal- 

 lows this was the most abundant species of the family. 

 Arrived at Carson April 15, 1868. 



Cooper, 1870. I saw them at Fort Mojave on the 22d 

 of February, but I have seen them at San Diego No- 

 vember 9 and January 27, so that if they do not winter 

 in the State they do not go far beyond it. 



Whidby Island, W. T. Lawrence Wessel. April 2, 

 1885. 



Walla Walla, W. T. Dr. Williams. May 25, three 

 birds; again May 26; still present August 9, 1885. 



213. Clivicola riparia (Linn.) BANK SWALLOW. 



San Bernardino. F. Stephens. Rare migrant through 

 the valley. 



Santa Cruz. Joseph Skirm. Common summer resi- 

 dent. 



Santa Cruz. A. M. Ingersoll. I have collected the 

 eggs here. 



Newberry. Not uncommon throughout California. 

 We occasionally saw this and the next species occupy- 

 ing their characteristic burrows. We sometimes prob- 

 ably confounded them as they are only to be distin- 

 guished by careful inspection. 



Heermann. Abundant. (At Sacramento City?) 



Contra Costa and Alameda counties (precise localities 

 not named). W. E. Bryant. Rare summer resident. 



Nicasio. C. A. Allen. March 19, 1876.
