be the 0. macrolophus, as shown by the whitish on the forehead and over the eye; the description, 
however, answers sufficiently well to O. stelleri. 
The Pica cyanoclilora of Wagler, Syst. Av. 1827, No. 9, Pica, and the Graculus (error for 
Garrulus) mela,nog aster, Vieillot, Nouv. Diet. XII, 1817, 478, referred to this species by authors, 
do not answer at all to it.

CYANURA MACROLOPHUS, Baird. 
Long-crested Jay. 
Cyanocitta macrolopha, Baird, Pr. A. N. Sc. Phila. VII, June, 1854, 118. Albuquerque. 
? Gamdus stelleri, Swainson, F. Bor. Am. II, 1831, 294 ; pi. ]iv. The plate, probably, if not the description. Head 
waters of Columbia. Not Corvus stelleri of Gmelin. 
Sp. Ch. — Crest nearly twice the length of the bill. Tail moderately graduated ; the lateral feathers about .60 of an inch 
shorter than the middle. Fourth and fifth quills longest ; second shorter than the secondaries. Head all round, throat and fore 
part of the breast, black, the crest with a gloss of blue ; rest of back dark ashy brown with a gloss of greenish. Under parts, 
rump, tail coverts, and outer surfaces of primaries, greenish blue ; greater coverts, secondaries, and tertials, and upper surface 
of tail feathers, bright blue, banded with black ; forehead streaked with opaque white, passing behind into pale blue ; a white 
patch over the eye. Chin grayish. Length, 12.50 ; wing, 5.85 ; tail, 5.85 ; tarsus, 1.70, (8351.) 
Hab. — Central line of Rocky mountains to table lands of Mexico. 
This species is very similar to the C. stelleri, but is readily distinguishable on comparison 
The most striking peculiarities are the much longer and fuller crest, the streaks on the forehead 
white, not blue ; and the white patch over the eye, not found at all in stelleri. The head is 
much blacker ; the crest feathers having also a gloss of blue, instead of opaque dark brown. 
The back is dusky bluish ash, not opaque brown. The chin is more gray; the blue of the 
breast extends further forward and is much less abruptly defined. The black bands on the 
wing feathers are more distinct, especially those on the greater coverts, which, obsolete in 
stelleri, are very conspicuous in the other.
