:{7. Marila collaris (Donovan) 



K.iN(i-NECKED Duck 



Rare migrant. At present known deiinitely from two localities only. Two 

 birds were taken froni a flock of eight or nine on Storey Creek, near Belgrade, 

 Gallatin County, October 10, 1912, by Thomas (Saunders, 1915d, p. 2.S8), and 

 three more were taken from a flock of fifteen in the same locality November 17, 

 1914 (Thomas, MS). Dr. Coucs mentions a specimen of this bird in "Daw- 

 son's collection" (1874b, p. 651) but as the locality and date are unknown, it is 

 doubtful whether the bird came from JMontana. This may be the same Dawson 

 who collected a specimen of the Hudsonian Godwit, "east of the Jlilk Rivei'" 

 and the dnck may have come from that region. Reported from swampy ground 

 in Glacier National Park in suunnei- (F. M. Bailey, 1918, p. 53).
