 continent, breeding from Texas to Alaska, and -wintering abundantly from the Middle 

 districts southward to Guatemala, Mexico, Cuba, and Jamaica, Eeplaced in South

1 have found the Shoveller to be abundant in season in all parts of 

 tlie West, and determined its breeding in Northern Dakota, where I 

 found young still unable to i3y in August, on the Mouse Eiver; and in 

 Montana, along the Milk Eiver and its tributaries, where the bird is 

 coiiiiiion through the Rummer. The eggs have not, so far as I know, 

 been described from American si)eciuiens. They measure on an aver- 

 age 2.10 iu length, by 1.50 in breadth ; the shape is as usual in the 

 family; the color a uniform dull, pale, greenish-gray, sometimes with a 

 faint bluish tinge. These eggs were taken on the Yukon; the nest com- 

 plement was eight. Others from the region last mentioned are entirely 

 similar.
