iEgialitis semipalmata Bonap. Semipalmated Plover. 



First noted May 23, 1001, when a number were seen on the shore 

 of the lake near Fort Chipewvan. The species was next met with on 

 some low, sandy islands in the lower part of Slave River, where 

 several pairs, undoubtedly breeding, were seen July 3. It was not 

 again noted until we were ascending the Athabaska, where several 

 migrants were seen at Middle Rapid, 40 miles below Grand Rapid, 

 on August 15, and several above Pelican Rapid August 24. 



J. C. Ross reports this species as abundant in summer on 

 Boothia " Walker records several taken in June and July, 1850, at 

 Port Kennedy. 6 Kennicott mentions taking this species at Fort 

 Resolution on May 23, I860. Ross listed it as common in the Mac- 

 kenzie River region and as having been collected at Fort Simpson; d 

 MacFarlane found it quite common on the Arctic coast [Franklin 

 Bay], along Anderson and Lockhart rivers, and between Fort Ander- 

 son and Fort Good Hope/ Sharpe records specimens from Fort 

 Simpson and Horton River.^ The bird catalogue of the National 

 Museum shows that specimens were received from Slave River, Big 

 Island, Fort Resolution, Fort Simpson, and Franklin Bay. Russell 

 records two specimens taken June 2 and 12, 1803, at Fort Chipewvan. 

 where he regarded it as not common." Seton records the bird as 

 breeding on Artillery Lake in 1007.' 1 



.ZEgialitis hiaticula (Linn.). Ring Plover. 



This wide-ranging plover, a regular breeder about Greenland, 

 Cumberland Gulf, and other localities in that region, is included 

 among the birds of the Mackenzie region on the authority of Baird, 

 Brewer, and Ridgway, who state : "An undoubted specimen of it 

 has been taken at great Slave Lake." ' 



Arenaria interpres morinella (Linn.). Ruddy Turnstone. 



This showy species occurs in the Mackenzie apparently only in 

 spring, as it is migrating to its breeding grounds on the shores and 

 islands of the Arctic Sea. 



While Ave were coasting along the north shore of Athabaska Lake, 

 about 10 miles northeast of Fort Chipewvan. May 25, L901, we saw
