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 Carcross, 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
oceurrences 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
