The vocal apparatus of this species is peculiar, causing its remarkably raucous voice. 

 Richardson simply states that "a fold of the windpipe enters a protuberance on the 

 dorsal or interior aspect of the sternum at its upper part, which is wanting in both 

 Cygnus ferns and hewickii." Mr. Yarrell, as above, has made the organ the subject of a 

 more extended article. In C. americanus, according to Audubon, the trachea " reaches 

 the curve of the fnrcnla, bends a little upward, and enters a cavity formed on the ster- 

 num, along which it passes to the length of six inches, bends upon itself horizontally, 

 returns, passes up between the crura of the furcula, bends backward and enters the 

 thorax." The external distinctions are the (usually) twenty-four-feathered tail of 

 buccinator, and wholly black bill rather larger than the head, with the nostrils fairly in 

 its basal half; in C. americanus the tail having usually only twenty feathers, and there 

 being a yellow spot on the bUl, which is shorter than the head, with the nostrils at its 

 middle. The superior size of C, tuccinator is another mark, though one not always 

 reliable. Audubon mentions one nearly ten feet in alar expanse, and weighing above 

 thirty-eight pounds. 



I have observed the Trnmpeter Swan on but few occasions, in Dakota 

 only, late in September and during the first half of October, when the 

 birds were migrating southward with great numbers of Canada and Snow 

 Geese and various Wild Ducks. Their loud and strange — almost start- 

 ling — notes were oftenest heard during the night, as the birds passed 

 overhead ; but I also saw some Swans flying in the day time near Fort 

 Stevenson, on the Upper Missouri. According to Dr. Hayden, the 

 birds breed in the Yellowstone region, as they also do, according to 

 other writers, in Minnesota and Iowa. We have other accounts of their 

 breeding in Alaska ; and Dr. Eichardson, who gives it as the common-
