belong to a recognizable race, one bird from Rocklyn, Lincoln Co., 

 Washington/ and one from Alix, Lacombe Co., Alberta,^ are gray 

 when compared with Ontario birds, and a series of inter-raountain 

 birds might repay examination. Little can be deducted from 

 measurements in the series before me, the Queen Charlotte 

 Island birds are large, the wing averaging 5.53 in. in the three 

 females, while five Ontario females average 5.40 in. 



Note. — Since the above was written I have examined two more 

 of the dark race, one of them a male. 



A NEW FORM OF CHLOEPHAGA HYBRID A. 



BY JOHN C. PHILLIPS. 



While on an expedition to the Falkland Islands in the interest 

 of the Museum of Comparative Zoology in 1915-16 Mr. W. S. 

 Brooks obtained a series of Chloephaga hyhrida from West Falkland. 

 This island form is larger in its several measurements than birds 

 from the Straits of Magellan, and seems to be worthy of separation. 

 It may be known as 



Chloephaga hybrida malvinarum subspec. nov. 



Type from Port Stephens, West Falkland Isle. No. 70476 M. C. Z., 

 adult d^ collected 13th December, 1915, by W. Sprague Brooks. 



Characters similar to C. hyhrida hyhrida from Patagonia and the Straits 

 of Magellan, but larger, especially in length, depth and breadth of culmen. 

 Pileum in the females, paler and more grayish; drab to light drab (Ridg- 

 way, 1912), instead of cinnamon brown. This character holds good for 

 all five of the Falkland Island females and for the M. C. Z. series from 

 the Straits of Magellan region.
