BIRDS—CORVIDAE—CYANURA MACROLOPHUS. 583 
In addition to the peculiarities of coloration, the bill is much more slender, and the tail less 
rounded. 
The bird figured by Richardson in Fauna Boreali Americana appears to be this species, from 
the white forehead and patch above the eye; the description, on the contrary, applies pretty 
well to stellerc. 
Recognizing fully the close relationship which the present species bears to C. coronata! of 
Swainson, I am yet inclined to consider it as distinct, notwithstanding a previous impression to 
the contrary. Swainson’s species appears to have the same long crest and the white superciliary 
patch, but it is described by him as blue, the sides of the head blackish, the wing coverts 
and tertials with blackish lines. As no mention is made of such lines on the tail, it is presumed 
that they are wanting. Bonaparte says the bird is entirely blue, the head duller, but with a 
bluer crest, the quills and tail feathers obsoletely banded. He adds that the adult has the head 
blackish ; the young with the head blue. Cabanis says that the crest is blackish blue, the rest 
of the head and fore neck more or less blackish according to age. In the present bird the head 
and neck all round are black, and the crest having only a gloss of blue, scarcely appreciable, 
and the tail is very distinctly banded with black. 
There seems to be a regular succession of jays of the present group between two extremes of 
color. Thus, the C. stellerit has the head and neck opaque black, with a frontal wash of dark 
blue. C. macrolophus has the head even blacker, the crest only glossed with blue terminally, 
the frontal wash and a superciliary spot whitish; the tail and wings strongly banded with 
black. C. diademata, Bonap., from southern Mexico, apparently lacks the superciliary white 
spot, the general color is ashy, the rump and abdomen blue. The quills and tail feathers are 
conspicuously banded. It differs from macrolophus in having the crest only black, and the color 
more ashy. C. coronata has the head and neck with the crest bluish, the sides of the head black, 
a whitish frontal and superciliary spot; and finally C. galeata, Cab., (Mus. Hein, 222,) from 
Bogota, has the head entirely blue, the borders of the crest only blackish. 
The Garrulus stelleri of the F. B. A. appears to be the present species, and one strong reason 
for believing it distinct from the coronata is the fact, that Swainson did not identify his supposed 
stellert with the bird he had described only a few years before as Garrulus coronatus.
