 The Californian Jay has been hitherto confounded by American ornithologists with 

 the Mexican G. ultramarinus., accurately described by Prince Bonaparte, in the 

 Journal of this Society, in 1825, and afterwards described and figured by Tem- 

 minck in the Planches coloriees, 439. It is strange that the Prince himself should 

 have committed the same error of confounding the two species in his Comparative 

 list of the Birds of Europe and North America, quoting at the same time Audubon's 

 plate and description, which is clearly the Californicus. 



The following are the distinctions between the two species :
