 the preceding species, the Barhary Partridge has failed to

 Virginian Colin {Ortyj- virfiln'ianus), thousands of which 

 have been brought over from North America during the 

 present century, and turned loose, without having succeeded 

 in permanently establishing themselves. This species is 

 therefore omitted from the present Edition.
