be the C. macrolcphus, as shown by the whitish on the forehead and over the eye ; the desci iption,. 

 however, answers sufficiently well to C. stelleri. 



The Pica cyanochlora of Wagler, Syst. Av. 1827, No. 9, Fica, and the Graculus (error for 

 Garrulus) melanogaster, Vieillot, Nouv. Diet. XII, 1817, 478, referred to this species by authors, 

 do not answer at all to it.

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. Tlie 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.
