* The late Mr. G. R. Gray, in the 'Hand-Ust' (ii. p. 11), gives as a synonym 

 of this genus, " Corcu; Bp. 1850." In the 'Conspectus,' Bonaparte does not 

 use tlie name in a generic sense, but separates the genus Corvus into sections, 

 one of which he calls Coraccs and another Cornices. It is therefore a mistake 

 to crecUt Bonaparte with the manufacture of the genera Cora.v and Comix.
