 culiar noise, that its trachea! artery or windpipe may 

 probably bear some affinity or resemblance to that 

 of some of the Cracidae, in which this organ is great-

 of its external beauty, than for its excellent flavour 

 as a wholesome and nutritious food. 



In size it exceeds all the other Columbine species, 

 being from twenty-seven to twenty-eight inches in
