ground; it contained one egg. At Calais, Me., ac- 

 cording to the excellent authority of Mr. Boardman, 

 the bird is a common summer resident, and breeds. 

 The eggs have been described as measuring 0.70 by 

 0.65 of an inch ; with a bluish-white ground, with 

 purplish and brownish blotches of several shades, 

 chiefly wreathed about the larger end.

 DENDRCECA DISCOLOR ( V.) Bd. 



Chars. Above, yellow-olive, the back with a patch of brick-red 

 spots ; forehead, line over eye, two wing-bars, and entire under 

 parts rich yellow ; side of head with a V-shaped black mark, con-
