which, according to the figure accompanying Mr. Newton’s paper above referred to, are o f a greenish stone-
colour, with a few dirty stains all over the surface, probably obtained by contact with the materials upon
which they are laid. They measure two inches and three-eighths in length, and one inch and five-eighths
in breadth.
The male has the head and upper part o f the neck white ; between the bill and the eye on each
side a patch of sea-green, which nearly unite on the forehead ; each eye surrounded by a ring of
black, broader behind than in front; on the occiput a broad band o f verditer green; from the lower
mandible down the centre of the throat a streak o f blackish brown, which very nearly approaches the broad
band o f deep bluish black encircling the base o f the throat, and which is united behind to the bluish-
black o f the back and upper tail-coverts ; below the bluish-black neck-collar a crescentic mark o f white ;
wing-coverts white; primary wing-feathers and tail deep brown ; secondaries and tertiaries white on the
inner, and deep blue on the outer web; narrow inner web o f the scapularies white, the broader outer web
deep blue ; breast and abdomen chestnut, fading into buff on the flanks, and deepening into blackish brown
in the centre; vent and under tail-coverts very dark brown; just before each wing a few o f the white
feathers of the sides o f the breast are tipped with black, forming a small oblong patch; bill deep olive, with
a yellower nail ; ¡rides brown; feet dark olive-brown, the webs darker, inclining to black.
The female, as stated by Mr. Yarrell, so closely resembles the females o f the Eider and King Ducks, that
the only difference necessary to be noticed is that the greater coverts and secondaries are tipped with white,
forming two bars, between which is a bluish-black speculum.
The front figures in the Plate represent two males, the size o f life, with a reduced figure o f the female in
the distance, and were drawn from specimens obtained from the Waranger Fjord by Mr. Alfred Newton.
