NOKTH AMERICAN FAUNA. 



[NO. 27. 



in the Athabaska Pass, September 29, 1898.* Seton records the pipit 

 from Clinton-Colden Lake.^ 



J. Alden Loring reported it common at Edmonton, September T to 

 26, 1894, taking two specimens on September 9. In 1896 he found 

 it common above timber line in the mountains 15 miles south of Henry 

 House, xA.lberta, July 3 to 21; and in the early autumn reported it 

 common in the valleys between Jasper House and Smoky River, tak- 

 ing two specimens on Sulphur Prairie, Grand Cache River, about 70 

 miles north of Jasper House, on September 12. 



Cinclus mexicanus unicolor Bonap. Northern Dipper. Water OuzeL 

 This species was first recorded from the region by Bonaparte, who 

 described a specimen in the collection of Mr. Leadbeater, said to have 

 come from Athabaska Lake.'^ Concerning the source of this speci- 

 men, Richardson says : 



Three specimens of this bird were procured by Mr. Drummond near the 

 sources of the Athabasca River, on the eastern declivity of the Rocky Moun- 

 tains, * * * Several specimens, obtained at the same locality and at the 

 same time with Mr. Drummond's, came into Mr. Leadbeater's hands through 

 the Hudson's Bay Company, one of which has been described and figured by the 

 Prince of Musignano in his splendid American Ornithology.*^ 



It is highly probable, therefore, that in this, as in several 

 other cases, Bonaparte was either misinformed regarding the locality 

 of the specimens, or applied the name 'Athabasca Lake,' wdiich he 

 sometimes qualified by the clause " near the Rocky Mountains," ^ to 

 some lake near the source of Athabaska River. 



Mr. Ridgwa}^ has recently revived the name Cinclus unicolor^^ pro- 

 visionally applied by Bonaparte to this specimen, so that the correct 

 location of the type locality becomes highly important. 



Two specimens of this bird, taken by William Brass at Fort Hal- 

 kett, British Columbia, on the upj)er Liard River, December 10, and 

 ' December ', 1862, and now in the National Museum, were recorded 

 by Baird.'* 



J. Alden Loring, in the autumn of 1895, saw an individual of this 

 species in the mountains west of Henry House, and observed three in 

 the same general region in the autumn of 1896. In the late summer 

 of the same year he saw several along streams in the high mountains 

 between Jasper House and Smoky River.
