516 ORNITHOLOGY AND OOLOGY. 



Female. With the head and body above, dark-brown ; the chin more plumbeous ; 

 the lower part of neck, breast, and under parts generally, except the central region 

 (which is white), duller and lighter brown; a whitish patch in front of the eye, and 

 a rounded spot just behind the ear. 



Length, seventeen and fifty one-hundredths inches; wing, seven and seventy 

 one-huudredths; tarsus, one and forty-eight one-hundredths; commissure, one and 

 fifty-four one-hundredths inches. 



Hob. Northern seacoast of northern hemisphere. 



The Harlequin Duck is very rare in Southern New Eng- 

 land, and is seldom met with here south of the most north- 

 ern portions on its coast. There it is pretty abundantly 

 seen as a winter visitor. It greatly resembles the following 

 in its general characteristics. I know nothing of its breed- 

 ing habits. 



" The nest is composed of dry plants of various kinds, arranged 

 in a circular manner to the height of three or four inches, and lined 

 with finer grasses. The eggs are five or six, rarely more, measure 

 two inches and one-sixteenth by one inch and four and a half 

 eighths, and are of a plain greenish-yellow color. After the eggs 

 are laid, the female plucks the down from the lower parts of her 

 body, and places it beneath and around them." 



HARELDA, LEACH. 



" Harelda, LEACH (1816)," Gray. (Type Anas glacialis, L.) 

 Bill shorter than the head and tarsus, tapering laterally to the end; the nail 

 very broad, occupying the entire tip ; lateral profile of lower edge of upper mandi- 

 ble straight to near the end, then rising suddenly to the prominent decurved nail ; 

 nostrils large, in the posterior half of the bill, their centre about opposite the middle 

 of the commissure; tertials long, lanceolate, and straight; tail pointed, of fourteen 

 feathers, the central feathers very long, equal to the wings ; bill with almost no pos- 

 terior lateral upper angle ; the feathers of the sides advancing obliquely forwards ;
