Gmel. 1783) has been thus quoted. But the name of Pallas has, 

 without doubt, the priority in this species, as I have shown above (p. 189), 

 for which both Bechstein's name for this and Gmelin's olor must give 

 way, and I cannot see but that the authors, who only admit one genus 

 of Swans, viz, Cygrms, must adopt the name of Pallas as the oldest 

 for the present species. It is certainly a serious matter to transfer the 

 name, which the Mute Swan has borne so long, to the Hooper, but if 

 we consider the right of priority, there is nothing else to be done. In 

 this case it does not depend upon a question which can be disputed, 

 how the old authors' descriptions can be interpreted (as, for examj)le, 

 with Sterna Mr undo and Stercorarius parasiticus). [See the note under 

 Cygnus gibbus.]
