"[ HE windpipe in the male of the Golden Eye, is of a curious con- 
ftruction, and the labyrinthic part different from any other, a 
fingular enlargement taking place about the middle. This fwelling 
or ventricofe part, confifts of divers plaits or joints placed obliquely, 
not differing in texture from the other parts of it, and folding over 
each other, fo as to admit of being contracted into a very fhort 
compafs, or dilated to a great diftance, as the lengthening or fhorten- 
ing of the neck may require. In the recent ftate, thefe rings are by 
compreffion capable of being folded into a fpace of little more than 
an inch, but by extending, may be made to occupy four inches or 
more, and being cartilaginous, eafily recover their tone when left to 
themfelves. A perfect idea may be obtained by infpecting the plate 
in the Lin. Tranfaétions above referred to.

OUas trachea of the male of this bird greatly refembles, in the drum- 
like portion of it, that of the Pochard*, but the bony box-like 
portion is elevated, and fcarcely to be diftinguifhed from that of the 
Scaup +, except in being fmaller. The trachea alfo itfelf is of {maller 
dimenfions throughout: thefe comparifons cannot fail to identify the 
fpecies, if properly attended to.
