observed the species daily between Nahanni River and Fort Norman. 

 June (') to 10; between "Wolverene Rock and Fort Good Hope, June 18 

 to 21; and frequently on the lower Mackenzie and Peel, June 25 to 

 July 1. At Fort McPherson I noted it on July 4. 15. and Id; and on 

 my return trip saw a few near Fort Providence. July ii!>. 



Larus brachyrhynchus was first described by Richardson from a 

 young female taken at Fort Franklin, Great Bear Lake. May 23, 

 1820." Another specimen, an adult male, killed at the same place, 

 June 7, 182G. and recorded under the name Larus canus? is referable 

 to the same species. Ross next referred to it as a bird of this region 

 under the name Rissa septentrionalis, recording it as common on 

 Great Slave Lake, and as having been collected at Fort Simpson.' 

 Baird, Brewer, and Ridgway recorded specimens taken during the 

 breeding season on Slave River, and at Fort Resolution. Big Island, 

 and Fort Rae : and eggs from Fort Resolution. Fort Raie, Anderson 

 River, and Peel River. They also describe the location of various 

 nests found by MacFarlane. One nest, merely a cavity in the sand, 

 was found on Lockhart River. May 28; another found June 10, near 

 Fort Anderson, was placed on a stump 4 feet from the ground; 

 another found June 21, near Rendezvous Lake, was in a tree at least 

 10 feet from the ground.' 7 Specimens from Fort Resolution and Fort 

 Rae are still in the collection of the National Museum, and the 

 catalogue of the birds there shows that skins were received also 

 from Fort Simpson. Fort Norman, Pee! River, Anderson River, and 

 Great Bear Lake. A specimen collected by Frank Russell at Fort 

 Chipewyan in the spring of 1893 has been examined. 



Larus Philadelphia (Ord). Bonaparte Gull. 



This gull is a common breeder in suitable places throughout the 

 region north at least to the borders of the wooded country. In 

 1901 this bird was first observed on Slave River about 50 miles below 

 Fort Smith, Mackenzie. June 30, when several were seen. A num- 

 ber were observed, and one was collected. 25 miles below there on 

 July 1. and during the next two days the species was found to be 

 common along the lower part of the river. Though doubtless 

 occurring, it was not seen after we reached Great Slave Lake. 



In 1903 we noted three individuals about a small pond 70 miles 

 north of Edmonton, Alberta, May 14. and one near Athabaska 

 Landing. May 15. We next saw the species on the lower Athabaska 

 near Poplar Point, May 30. While crossing Great Slave Lake. 1
