386 SPOTTED GROUSE. 
conspicuous whitish dots on their inner web besides; the 
secondaries are also dusky, but in them the spots take the 
appearance of bands continued across the whole feather, of 
which bands there are three or four, including the terminal ; 
the inner secondaries become darker and darker as they approach 
the body, the white becomes rufous, the dots are more frequent, 
and they become confounded with the scapulars, and are 
banded and mottled with various tints of black and rusty ; 
the lower wing-coverts, and long axillary feathers, are pure 
white, the outer coverts being marbled with dusky. The tail 
is composed of eighteen feathers; it is cuneiform, very short, 
and entirely hidden by the coverts, except the four middle 
feathers ; the two middle feathers are flaccid, narrow, equal in 
breadth throughout, longer than the others by more than an 
inch, rusty, crossed by chained bands of black, and dotted with 
black and whitish at tip; the two next are also longer than the 
others, nearly whitish, but almost similar in shape, markings, 
and texture, to the longest; the lateral decrease in size very 
fast from the centre, but by regular degrees, and are remark- 
ably stiff, somewhat like those of woodpeckers, wider at base 
and tip than in the middle, pure white at the end and on the 
inner web, the shaft black, and the outer web dotted with 
blackish ; they are deeply emarginate at tip, the inner lobe 
being longer, acute, and singularly shaped.
