Hah. 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 diflerent specimens. 



There can be no doubt that this is the Motacilla dominica or' 

 Linufens. 



This species, although not belonging to either the middle or 

 western provinces of North America, w^as 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.
