BOHEMIAN WAXWING. 
77 
Length, eight and a half inches ; extent, fifteen ; hill, 
three quarters of an inch long, black, paler at the base 
of the under mandible ; irides, reddish, often quite red; 
nostrils, entirely uncovered. From the base of the ridge 
of the bill arises, on each side, a velvety black line, 
bordering the forehead, and spreading on the ophthalmic 
region, and surrounding almost the whole crown ; throat 
also deep black. The anterior part of the head is bright 
bay, behind passing gradually into vinaceous drab ; the 
feathers of the crown are elongated into a crest 
measuring nearly an inch and a half; base of these 
feathers, blackish ; middle white, whole neck and hind- 
head and breast, cinereous drab, slightly tinged with 
vinaceous, and passing by degrees on the posterior parts 
above and beneath into pure cinereous, slightly tinged 
with bluish, which predominates on the rump and upper 
tail-coverts. The black of the throat is somewhat 
margined with bright bay, and is separated from the 
black of the eye by a slight obliterated w hite line. The 
cinereous of the belly and femorals is paler ; the vent 
and lower tail-coverts are chestnut rufous, and the 
feathers very long. The wings measure four and a 
half inches in length, the second primary is somewhat 
longer than the first, the others decreasing in succession 
rapidly. The upper tail-coverts are cinereous drab, 
like the back, the lower whitish gray; quills, dusky 
black, much paler on their inner vane towards the base. 
The first is unspotted, the second has a slight mark of 
white on the outer web at tip. This mark increases 
in size successively on the following, becoming a 
longitudinal spot, much larger on the secondaries, four 
of which are furnished with bright red appendages. 
Each feather of the winglet is broadly w hite at tip, 
constituting a remarkable white spot on the wing, wdiich 
appears to be on the primaries. No yellow w hatever 
is observable on the wing. The tail is three inches 
long, black, broadly tipped with pale yellow for half an 
inch, dark bluish gray at base. Tarse, wdiich is three 
quarters of an inch long, and feet, black.
