Hab. Eastern province of U. S., north to Washington and Cleveland; in 
winter abundant in Cuba; St. Domingo and Jamaica; Mexico (as far north 
as Colima on west coast) and Guatemala. Resident in Jamaica? 
Specimens from the West Indies exhibit the same variations in 
the extent of black on the forehead, and in the color of the super- 
ciliary stripe, as North American. The portion of this stripe 
anterior to the eye is sometimes white, sometimes bright yellow, 
and sometimes a mixture of the two; but I am entirely unable to 
base a second species upon such diversities. All I have seen from 
Mexico and Guatemala have this stripe white. There is a great 
variation in the length of the bills in different specimens. 
There can be no doubt that this is the Motacilla dominica of 
Linneus. 
This species, although not belonging to either the middle or 
western provinces of North America, was collected at Colima (west 
coast of Mexico), by Mr. Xantus. This is an interesting fact, but 
paralleled by the occurrence at Manzanillo, Mex. (the seaport of 
Colima), of Larus atricilla and Sterna antillarum (frenata), two 
species not known farther north on the Pacific coast, although 
occurring along the whole eastern coast of the United States. A 
specimen, killed June 4, by Mr. March, in Jamaica, would indicate 
that it breeds in that island, as well perhaps as in others of the 
West Indies.
