Description. 



Top and sides of the head and neck ash-gi-ay ; rest of upper parts olive-green, 

 brightest on the rump ; beneath dull-white, faintlj' tinged in places, especially on the 

 sides, with yellowish-olive ; eyelids and a stripe over the eye whitish ; a dusky line 

 from the eye to the bill; outer tail feather with a white spot along the inner edge, 

 near the tip. Female, with the ash of the head less conspicuous; the under parts 

 more tinged with olive-yellow. 



Length, four and fiftj' one-hundredths inches; wing, two and seventy-five one- 

 hundredths ; tail, one and eighty-five one-hundredths inches. 



Tills bird is an extremely rare summer visitor in New 

 England. Mr. Allen says he has taken it on Sept. 19 and 

 May 29 : this shows that it passes north to breed, but where 

 it passes the season of incubation we are ignorant. The 

 species itself seems to be a very small one ; and, as the mem- 

 bers are so few, they may be easily overlooked in the 

 forest through the whole season, particularly as they are 

 quiet and retiring in habits. I think that, perhaps, the 

 wilder sections of Maine and New Hampshire may give it a 

 summer home, but of course can only judge from the above 

 reasons. 



Mr. Geo. A. Boardman says in the Am. Naturalist that a 

 few remain in his locality (Calais, Me.) through the season, 

 from which I judge that it breeds there.
