the eastern or western form. The specimen in question closely 

 resembles examples from Pennsylvania. Victoria, Tacoma and 

 Seattle were the ouly localities where Martins were noted. 



204. Petrochelidon lunifrons. Cliff Swallow. 



205. Chelidon erythrogaster. Barn Swallow. 



206. Tachycineta bicolor. White-bellied Swallow. 



207. Tachycineta thalassina. Violet-green Swallow. 



With the possible exception of P. lunifrons, which was not noted 

 west of the Cascades, 1 these Swallows were uniformly abundant 

 through the length and breadth of the land, up to an elevation of 

 5,000 feet, thalassina being noted 2,000 feet higher. 



208. Clivicola riparia. Bank Swallow. 



Found breeding along the Thompson River at Ashcroft, and 

 more abundantly at Kamloops. Its distribution in British 

 Columbia is very local. Not included in Messrs. Chapman's or 

 Fannin's lists. 



209. Stelgidopteryx serripennis. Rough-wing Swallow. 



Not as common but of the same distribution as Chelidon erythro- 

 gaster. 



210. Ampelis cedrorum. Cedar Bird. 



A common species, as erratic in presence and abundance as its 

 eastern counterpait. 



211. Lanius borealis. Northern Shrike. 



Two specimens from Vancouver Island are in the collection. 



212. Vireo olivaceus. Red-eyed Vireo. 



I did not find the Red-eye west of the Cascades, but over the interior 

 it was commonly distributed, and a few were found at Lac La 

 Hache. 



213. Vireo gilvus swainsonii. AVestern Warbling Vireo. 



Warbling Vireos abound in Washington and British Columbia. 

 As has been pointed out more fully in the Auk, birds from the 

 northwest indicate the tenability of swainsonii as a subspecies of 

 eastern gilvus. 



214. Vireo solitarius cassinii. Cassin's Vireo. 



This species is represented by specimens from nearly every local- 

 ity in British Columbia, including Vancouver Island, Lac La 

 Hache and Vernon. It is found in the open timber at higher eleva-
