--Gould, Proceedings of Zool. Soc., Part III. 
A FINE and, as far as I am aware, an unique example of this species of Pte7'oglossusioYm& part of the Cabinet 
of Natural History of Munich, so renowned from the circumstance of its containing the collections formed in 
the Brazils by those scientific travellers Drs. Spix and Martius. This fine collection, which is particularly 
rich in birds pertaining to the present family, was in the most liberal manner thrown open for my investiga¬ 
tion, when I hailed with pleasure the appearance of the fine species here figured, exhibiting as it does those 
peculiar markings of the bill which had heretofore been confined to one known sjiecies only, the Pteroglossus 
inscriptus. Its superiority in size and its black under mandible will at all times serve as a distinctive mark 
between the two species. No information relative to its history and manners appears to have been ascertained, 
further than that it was a male, and received from the Brazils, in all probability from near the Amazon.
