1920.] Birds of Saskatcheivan and Manitoba. 397 



birds collected in 1014. I had already examined those at 

 Regina in 1915, and I am indebted to Mr. H. H. Mitchell o£ 

 the Provincial Museum there for the loan of those that were 

 needed for comparison. The data on the specimens them- 

 selves are exceedingly full, and Captain Buchanan has 

 furnished me with a list of them, together with notes on the 

 colours of the soft parts, food, etc. ; from this I have quoted 

 when necessary. The nomenclature used is that of the 

 A. 0. U. Check-List of 1910. 



Colym'bus holboelli. Holboell's Grebe. 



Set of five eggs taken on Churchill River, G June ; bird 

 seen at close range. 



Gavia immer. Loon, Great Northern Diver. 

 An adult taken on Reindeer Lake, 8 July. 



Larus brachyrhynchus. Short-billed Gull. 



An adult female taken on Reindeer Lake, 9 July, one 

 more seen on same date ; this is very far east for the Gull. 

 " Iris clear blackish grey ; edge of eyelid surrounding eye 

 deep orange-chrome ; corners of mouth pure orange-chrome ; 

 bill evenly coloured dead yellow ; feet pale Avhitish yellow. ^^ 



Dr. Oberholsor regards this Gull as a subspecies of Larus 

 canus ■*. 



Larus delawarensis. Rino-billed Gull. 



A male taken on Ile-a-la-Crosse Lake, 23 May; adult, except 

 for the black primaries and terminal black band of the tail ; 

 probably a non-breeding bird. "Bill medium dai'k greenish- 

 yellow, with strong black ring around bill a short distance

 bird.
