the lake and ascending the river, this duck began immediately to replace in a 

 great measure the other species, and following the stream up till it was 

 inclosed on either side by the canon's rocky sides, the Golden Eyes (per- 

 haps both species) were still present in great numbers. They appeared to 

 enjoy especially fishing in the midst of the rapids, and where the cm-rent was 

 swiftest, allowing themselves to di-ift at will, and regaining their lost positions 

 when so minded by flying up stream, their wings just skimming the surface 

 of the water.

Barrow's Golden Eye has hitherto been known as a bird of the 

 coast, principally from the Atlantic side, where in winter it reaches to New 

 York. Even, however, on the Massachusetts coast it is rare, though a few 

 find their way into the markets each winter. On the west coast, it is known 

 from Sitka and the Yukon, Alaska. It was first obtained in the interior of 

 the United States by Dr. Hay den; afterward by our party in 1872, and 

 since then it has also been reported as a bird of the Rocky Mountains (lat. 

 49°) by Dr. Coues. I am inclined to regard it as a species occumng regu- 

 larly and in considerable numbers on Utah Lake, where our specimens, 

 a pair, were taken, and where the gunners assured ixs they shot more or 

 less every winter, though they considered it less abundant than the preced- 

 ing species, from which they distinguished it by its larger size.
