The representation of this species given by Madame Knip on 

 plate 34 of her work is so badly executed that it is impossible to 

 recognize what is intended ; for it certainly resembles no species that 

 was ever seen. Therefore Bonaparte was perfectly justified in

 good idea of this species is obtained. It is very safe to say that 

 unless the originals of some of Madame Knip's plates had been 

 preserved in the Paris Museum to show what the species really 

 were, they would always have remained a stumbling-block to ornitho-
