Little more is now known respecting this species than was recorded in the first edition of this work, nearly 
twenty years ago. The two specimens from which my figure, was taken had been sent to me by my valued 
correspondent D. Christie, Esq., of Popayan, and I have never received a third example ; the celebrated 
traveller M. Delattre, however, met with it in his rambles, and sent two or three specimens to Europe, one 
of which is in the Museum of the Jardin des Plantes at Paris, the other in the British Museum. The bill 
of the latter specimen is very short, while that of the example in the Jardin des Plantes is fully as long as I 
have represented it in the former edition of my Monograph; and, as well as the specimen in the British 
Museum, is in every respect richer in colour, particularly in the greenish yellow on the sides of the mandibles ; 
the yellow of the rump too is extremely beautiful and well-defined, while the back is ornamented with a 
collar of bluish grey. The harlequin-like markings of the bill in this species not only render it conspicu¬ 
ously different from the other members of its genus, but from every other species of the family. 
The Grey-breasted Arapari is an inhabitant of the mountains, and is only to be found on the highest wooded 
portion of the Andes, for which elevated and cold situations the full and downy texture of its plumage 
admirably adapts it, a feature equally characteristic of the three other species of this form since discovered. 
The specific name given to this bird refers to the beautiful silvery lustre which pervades the fine grey tints 
spread over the breast and under surface. 
The figures are of the natural size.
