cially on the upper part of the back, and are moreover 
sprinkled with white somewhat tinged with rusty ; the 
scapulars and wing-coverts are besides shafted with 
white somewhat dilating towards the point, the scapulars 
being of a deeper black ; the spurious wing and primaries 
are plain dusky, with paler edges, the outer with some 
indications of whitish dots (generally found in grouse) 
on the outer vane, but no regular white spots ; the 
secondaries are tipped with white, and those which are 
next to the primaries nearly plain on their inner web ; 
the primaries are rather slender, the inferior surface of 
the wings is of a very pale silvery gray ; the under 
wing-coverts and long axillary feathers being pure 
silvery white, excepting on the lining of the wing, 
which is dusky blackish ; the wings are twelve inches 
long ; the breast is grayish, somewhat mottled with 
black ; on each side below is a pure white space, some 
of the feathers of which are tipped or banded with 
black ; the large feathers of the flanks are blackish, 
shafted with white, crossed by several whitish bands, 
and sprinkled with yellowish ; a broad oblong patch of 
deep brownish black occupies the whole of the belly 
and vent, the outer feathers being shafted with white, 
and broadly white at the point of their outer webs; 
the femorals and small feathers of the tarsus extending 
between the toes are yellowish gray, minutely waved 
with blackish ; the tarsus measures two inches ; the 
toes are dusky black, and the pectinated row of processes 
long, strong, and dingy whitish ; the nails, blackish ; 
the whole base of the plumage, with the exception of 
that of the neck beneath, which is white, is of a dusky 
gray. The tail ns ten inches long, and in colour, is, as 
well as its coverts, in harmony with the rest of the 
plumage ; the ground colour is blackish, and crossed or 
rather mottled with bands of whitish spots disposed 
irregularly, between which are small additional darker 
spots ; the two middle ones are mottled all over, but the 
others are almost immaculate on their inner vane, and 
at the point, — hence the lower surface of the unexpanded 
tail is of a silvery gray, much darker than that of the
