We have now a large series of specimens of this species. 

 These show a considerable amount o£ variation, due, we 

 believe, wholly to the age of the plumage of different indi- 

 viduals. These variations, as shown by birds from Cozumel 

 Island alone, cover all the differences said to exist between 

 V. cinereus and V. magister, and we do not see how the 

 former can be maintained as distinct.
