1 HIS bird, by Dr. Latham, has been thought a variety of 

 the Tufted Duck, Anasfuligala ; but he appears not to have 

 seen it. The bill seems partly to warrant his opinion; but 

 if any thing is to be depended on in the plumage, we must 

 consider it a different species. It was sent from Yarmouth 

 by our friend D. Turner, Esq.
