thefe birds vary exceedingly before they arrive at mature plumage, 
for in one pointed out by this laft gentleman to me as a female, 
the chin and throat were black: head mottled green and black, in 
the manner of the Pewit Gull, before its final change into deep 
black: wings brown, with a rufous bar: under parts of the body 
pale yellow, but the middle of the belly inclined to rufous: the tail 
dark olive green, with the twa middle feathers nearly black.

TJ F the bird figured by Briffon, and that of Edwards be the fame, 
the laft is by much the biggeit, as appears by the Leverian Mu- 
feum, which contains fpecimens of beth. In Briffon’s bird the lore 
and chin only are black, but in that of. Edwards, the fore part of 
the head, chin, throat, and the wing coverts have a large portion 
of white: the yellow parts in Briffon’s bird are very full and bright, 
but in that of Edwards, of a greenifh yellow.
