This grand species was formerJy taken in abund- 
ance in Scotland, but at this pej'iod it is nearly if

with dusky feathers : beneath tlie eye a small spot 
of w’hite feathers : the head and neck of a dusky 
brown, sprinkled with small greyish white spots : 
the feathers of the hind head elongated, and, with 
those of the chin and throat, dusky black : the 
back and rump dusky ash, marked with innu- 
merable small zigzag white lines : the belly is black, 
with white spots towards its middle, and undulated 
greyish white stripes on its sides : the breast is of 
a fine dark glossy green : the wing-coverts are 
chesnut-brown, finely speckled with dusky, and 
striated with blackish lines ; at their tips pure 
white : the primary quills dusky brown ; the se- 
condaries the same, finely edged with whitish on 
their outer webs : the bend of the wing and under 
tail-coverts pure white : the tail consists of eigliteen

killed near the upper end of Loch Lomond, about thirty-five 
years since.
