* It is not often that I hare had occasion to differ from the conclusions of Count 

 Salvadori, whose judgment on vexed questions of nomenclature I have been able to 

 follow in the majority of cases, but his argument for the adoption of the genus Caica 

 seems to me to be the best that could have been employed to secure the rejection of 

 the name. If he had not so cleverly explained the complications which surround 

 its adoption, no one would probably have felt any qualms as to its recognition.
