BEWICK'S SWAN.

the impression that lie Lad recognized an example of this 

 American Swan in an immature bird purchased at a poul- 

 terer's at Edinburgh in February, 1841, and he described it 

 as such. Again, five Wild Swans were found in a poulterer's 

 shop in Edinburgh on the 26th December, 1879 ; and it was 

 stated that four of these on dissection also proved to be 

 C. americanus (Zool. 1880, p. 111). There seems, however, 

 good reason to doubt the correctness of the diagnosis, and 

 some remarks on the subject, with illustrations of the bills 

 of this and Bewick's Swan in the ' Proceedings of the Natural 

 History Society of Glasgow,' vol. iv. p. 318, maybe consulted 

 with advantage by those who are in haste to add fresh species 

 of waterfowl to the * British ' list. 



The vignette represents a front view of a portion of the 

 body of Bewick's Swan ; the anterior part of the descending 

 windpipe being turned aside to show its inner ascending 

 part, the muscles of voice, and the tendinous fascia stretched 

 across from one branch of the forked bone or merrythought, 

 over to the other, by which both portions are supported. 

 This, and other anatomical representations, necessarily very 

 much reduced in size here, will be found on a larger scale 

 in the sixteenth volume of the Linnean Transactions.
