Dafila acuia (Linn.). Pintail. 



The pintail was observed commonly in the marshes bordering 

 Rocher River on June 5, and on Slave River, between Fort 

 Chipewyan and Smith Landing, on June 6 and 7. 



Marila valisineria (Wilson). Canvas-back. 



We did not observe the canvas-back in life, but during our 

 return trip saw a number among the ducks which were being 

 salted for winter use at Fort Chipewyan. The marshes about 

 the delta of the Athabaska constitute one of its breeding stations. 



Marila marila (Linn.). Scaup Duck. 



These ducks were several times noted along the Athabaska, 

 between Boiler Rapid and Fort McMurray, May 27 and 29, 

 and were seen on the lower Athabaska on June 3 and 4. We 

 next noted it on the Nyarling on July 9. It was next observed 

 while we were ascending Slave River on October 1, when we 

 noted one near Point Brule*. We also observed a flock of about 

 twenty near Smith Landing on October 6, and noted the species 

 on the following day. It was a common duck in the store-houses 

 at Fort Chipewyan. 



Marila affinis (Eyton). Lesser Scaup Duck. 



The lesser scaup was observed in some grassy ponds on the 

 north shore of Aylmer Lake on August 17. It was conspicuous 

 among the ducks preserved in the store-houses at Fort Chipe- 

 wyan in early October. 



Clangula clangula americana Bonaparte. Golden-eye. 



This fine species was observed nearly every day while we were 

 descending the Athabaska River, May 17 to June 4. It was 

 common also along Rocher and Slave rivers, between Fort 

 Chipewyan and the mouth of the Peace River, June 5 and 6. 

 We saw it also near Salt River on June 27, and near Fort Smith 

 on June 28 and July 4. It was seen on Little Buffalo River on 

 July 9 and 11, and near Fort Resolution on July 16. This
