of them were of my creation. I have now rejected two of these, of 

 which I have not yet seen specimens, namely T. albicans and T. 

 brevirostris. And having again carefully compared specimens of 

 the other five species as here given, I cannot regard them otherwise 

 than as distinct ; and I believe Dr. Burmeister would agree with me 

 if he were to examine them, which he acknowledges he has never 

 had an opportunity of doing.

This species is distinguished from T. doliatus by its crested black 

 head and by the want of spots on the inner webs of the lateral rec- 

 trices. Prince Max of Neuwied's bird appears to belong to the 

 former species.

 and the hinder part of the neck is rather more mixed with white. 

 Below, the plumage is much whiter, the sides of the head are stri-
