river and on Brock's Lake near Camp 1. Near the latter place we were 

 shown a hollow tree where the species was said to have nested. At Camp 4 

 near Nevis is a pump house supplying water to the railroad some several 

 miles away. The engineer in charge told us that ducks frequently entered 

 the attic of his dwelling quarters through an open stovepipe hole and made 

 considerable scratching noise overhead. I climbed up into the space 

 through a man-hole but saw no indication of a nest. Without doubt these 

 must have been Golden-eyes that were attracted to the place but did not 

 find it satisfactory. Our specimens include representatives of two downy 

 broods and one adult taken on Brock's Lake, Camp 1, June 28 and downy 

 young above Nevis, July 6. 



26.* Charitonetta albeola. Bufflehead. — Two females with small 

 broods were seen on Brock's Lake near Camp 1 and afterwards occasionally 

 as far as Ross's Ranch, July 9. Young saw two at Camp 11, Little Sand- 

 hill Creek, September 14. Our specimens consist of downy young, Camp 1, 

 June 28. Also adults and downy young from Buffalo Lake, taken by 

 Horsbrough, June 21 and May and September 1914, who records several 

 nests. 



27.* Oidemia deglandi. White-winged Scoter. — White-winged 

 Scoters were common on the river as far down as Camp 5. There were 

 quite a number on Brock's Lake near Camp 1 and singles and small flocks 

 and pairs were encountered here and there flying up or down the river. 

 Both sexes were present in about equal numbers and a female taken on 

 Brock's Lake July 2 contained an egg nearly ready for deposition. The 

 residents, however, do not know of their nesting in the neighborhood and 

 were as curious as to where they nested as we were. We have another 

 specimen from Buffalo Lake, June 1915, taken by Horsbrough, who says 

 they nest late in the season. 



28. Erismatura jamaicensis. Ruddy Duck. — Dippie reports find- 

 ing eggs at Buffalo Lake, June 14, 1896, and Horsbrough also records a 

 nest there. 



29. Chen hyperboreus. Snow Goose. — We heard of white geese 

 being occasionally seen on the river but did not meet with any. Chas. 

 Sternberg reports seeing one near the Little Sandhill Creek, June 2. This 

 must have been a belated straggler. Horsbrough records both Greater 

 and Lesser Snow Geese from Red Deer and Buffalo Lake respectively. He 

 gives the length of the former as 27 inches but no further corroboration. 

 He is probably mistaken in his diagnosis. 



30.* Chen rossi. Ross Goose. — Two specimens in our collections 

 taken by Horsbrough, Buffalo Lake, September 26 and October 10, 1914. 

 He does not mention the species in his lists. 



31.* Anser albifrons. White-fronted Goose. — We have a speci- 

 men in the museum collection taken by Dippie on the Red Deer River, 

 Sept. 12, 1896. Horsbrough reports a specimen in October 1915. 



32.* Branta canadensis. Canada Goose. — A Mr. Krieger, upon 

 whose land we camped at Camp 1, told us that geese used to nest on the
