t The older authors apparently derived their nomenclature from the terras 

 in use in falconry ; and it is difficult to tell what their descriptions really were 

 intended for, as in several instances it is evident the Goshawk is mixed up with 

 the Peregrine. Two names have been adopted by modern writers, viz. Falco 

 communis and Falco percyrinus, titles founded by Gmelin on descriptions of his 

 predecessors. The latter has generally been adopted ; but inasmueli as both are 

 said to have yellow irides, they are both open to the same objection, though they 

 are otherwise good descriptions of the Common Peregrine. I prefer in this case 

 to employ the title of Falco communis of Gmelin, founded on the " Faucon " of 

 Brisson and Biiffon. There can be nfi doubt as to the species intended by the 

 latter, as will be seen bv the figure.'^ in the ' Planches Enliuninees.'
