This bird, by Dr. Latham, has been thought a variety of 
the Tufted Duck, Anas fuligala ; 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 
fly our friend D. Turner, Esq.
