 Society of London for the use of the Society's Rooms, in which the

 promoting in one of its most extensive departments, the object for which 

 the Society was instituted.

* Mr, Yarrell, having- 'since obtained four specimens in addition to those he 

 previously possessed, has more recently entered fully into the differences exist- 

 ing between the Hooper and the new species of Swan noticed above, for which 

 he has proposed, in a Paper read before the Linnean Society, the name of Cygnus 

 Bewickii. The most marked distinctions are in the anatomical structure of the 

 sternum, and of the trachea and its appendages. The external distinctions are 

 indicated by the following specific characters of the allied species, which are 

 given in the paper alluded to : — 



Ci/gnus ferus. Cygu, rostro semicylindrico atro basi lateribusque (his ultri 

 nares) flavis ; corpore albo ; rectricibus 20 ; pedibus nigris. 



Ci/gnus Beicickii. Cygn. rostro semicylindrico atro, basi aurantiaci ; corpore 

 albo; rectricibus 18 ; pedibus nigris.
