referable to the eastern subspecies, and to the western on just as strong 

 resemblances in other respects. The fact that so little is known of the 

 breeding ranges of the two forms is an added reason for conservative 

 systematic treatment of non-breeding birds. 



Heteroscelus incanus (Gmelin). Wandering Tattler 

 An adult male, a single bird (no. 44655), was shot by Brooks at 

 Careross, the evening of May 25. It was presumably en route to its 

 breeding grounds farther inland. 



Actitis macularia (Linnaeus). Spotted Sandpiper 

 Seen at Careross, May 22. Abundant in the Atlin region. Breed- 

 ing along the lake shore and along stream beds ; inevitably encountered 

 wherever conditions are favorable. During the second week in June 

 unfinished nests and incomplete sets were found; by the third week 

 in July young birds had appeared ; by the middle of August the young 

 were full grown and in the first fall plumage. The last spotted 

 sandpiper was seen at Surprise Lake, September 15. 



Numenius hudsonicus Latham. Hudsonian Curlew 

 One was shot near Atlin by one of the residents of the town, about 

 the middle of May, shortly before our arrival. I saw the mounted bird. 

 This is of interest as an inland occurrence of an usually maritime 

 species ; I know of no other occurrence in British Columbia away from 

 salt water. 



Oxyechus vociferus (Linnaeus). Killdeer 

 At Atlin, May 28, a pair of killdeers were found established in a 

 marsh immediately behind the town. They were seen there several 

 times, but apparently left without successfully nesting. On July 7 

 a single bird was seen on the shore of Lake Como, and on July 10 one 

 was flushed from a marshy spot in dense woods near that lake. These 

 occurrences constitute probably the northernmost records of this 

 species so near the coast, though inland it has been found somewhat 

 farther north, to Great Slave Lake. 



Charadrius semipalmatus Bonaparte. Semipalmated Plover 

 Present at Careross, May 22, and at that time in pairs and evidently 

 ready to nest. Fairly common in the Atlin region ; that is, a pair or
