formed by the melting snow. The bird was again noted May 18. On 

 May 26 it was common at the same place and several specimens were 

 collected. 



We have received two specimens, both males, taken near Fort 

 Providence, May 14, 1905, by Mills and Jones. 



Ross lists this species as occurring in the Mackenzie River region, 

 and as having been collected at Fort Simpson;" Baird, Brewer, and 

 Ridgway state that it was taken at Fort Simpson, Fort Resolution, 

 and Fort Anderson; 6 and the bird catalogue of the National Museum 

 shows that it was received also from Fort Rae. Oates records two 

 eggs taken by Collinson at Cambridge Bay, Victoria Land/' J. 

 Alden Loring saw four at Edmonton, September 25, 1894, taking 

 one specimen. 

 Pisobia fuscicollis (Vieill.). White-rumped Sandpiper. 



Ross recorded specimens taken at Big Island, Great Slave Lake,'' 

 and from Fort Simpson, noting the species as rare; € the catalogue 

 of the birds in the National Museum shows that specimens were 

 received also from Fort Resolution and Fort Rae. Baird, Brewer, 

 and Ridgway state that MacFarlane found the species breeding on 

 the Arctic coast [Franklin Bay], and on the Barren Grounds [east 

 of Fort Anderson], and describe eggs collected by him/ Among 

 sandpipers collected by Frank Russell at Fort Chipewyan, and now 

 in the Museum of the University of Iowa, are four specimens of this 

 species taken June 3 to 8, 1893; a specimen taken by Kennicott at 

 Fort Resolution, May 19, 18G0, is still in the National Museum. 



Pisobia bairdi (Cones). Baird Sandpiper. 



This is the sandpiper most characteristic of the Mackenzie region. 

 Its early appearance at Great Slave Lake at the close of the breed- 

 ing season seems to indicate that it nests at no great distance to the 

 northward, though probably not south of the Barren Grounds. 



In 1901 this bird was first met with on the Quatre Fourches marsh, 

 near Fort Chipewyan, where a small flock was seen and a female 

 taken May 24. On May 25, while we were coasting along the north 

 shore of Lake Athabaska to Point La Brie, we encountered large 

 masses of floating ice, on which were feeding several large Hocks of 

 this species, together with smaller companies of turnstones. Two 

 specimens were taken. We next met with the species on Great Slave
