HARLEQUIN DUCK. 127 



ils cream tint the longest, and, with the skinny part of the bill, form 

 two strong peculiarities of this species. 



The female measures nineteen inches in length, and twenty-seven in 

 extent ; bill exactly as in the male ; sides of the front white ; head, 

 chin, and neck ashy gray ; upper parts of the back and wings brownish 

 slate ; secondaries only, white ; tertials hoary ; the white secondaries 

 form a spot on the wing, bounded b}' the black primaries, and four 

 hoary tertials edged with black ; wlR)le lower parts a dull ash skirted 

 with brownish white, or clay color ; legs and feet as in the male ; the 

 bill in both is marked from the nostrils backwards by a singular heart- 

 shaped outline. 



The windpipe of the male measures ten inches in length, and has four 

 enlargements, viz., one immediately below the mouth, and another at 

 the interval of an inch ; it then bends largely down to the breast bone, 

 to which it adheres by two strong muscles, and has at that place a third 

 expansion. It then becomes flattened, and before it separates into the 

 lungs, has a fourth enlargement much greater than any of the former, 

 which is bony, and round, puffing out from the left side. The intestines 

 measured six feet ; the stomach contained small clams, and some gluti- 

 nous matter ; the liver was remarkably large.

This species is very rare on the coasts of the Middle and Southern 

 States, though not unfrequently found off those of New England, where 

 it is known by the dignified title of the Lord, probably from the elegant 

 crescents and circles of white which ornament its neck and breast. 

 Though an inhabitant of both continents, little else is known of its par- 

 ticular manners than that it swims and dives well ; flies swift, and to a 

 great height ; and has a whistling note. It is said to frequent the 

 small rivulets inland from Hudson's Bay, where it breeds. The female
