The pair were in full moult in the month of May. The eye-ring is noted as " black ; the lower 

 eyelid greenish grey ; the rest of the naked skin round the eye dark grey ; the iris dark brown ; 

 the feet dark grey, and the claws black." 



A single example of this Bucco occurred in a collection transmitted by Mr. H. W. Bates 

 from Ega, on the Amazons, of which I gave an account in the ' Proceedings ' of the Zoological 

 Society for 1857, so that it must also be found in Upper Amazonia. But it is decidedly a rare 

 species, and to be seen in very few museums. The only example I have been able to secure for 

 myself during many years' assiduous bu'd-collecting was purchased of Madame Verdey, of Paris, in 

 1871, and is labelled " Oyapok," though I am by no means sure of the correctness of the locality. 

 It is represented in the accompanying Plate (XXV.). 



The plumage of this specimen above is generally of a dull black, deep black on the head, 

 and glossed with greenish on the back. The outer secondaries and upper tail-coverts show slight 

 white marginations at the tips. A narrow frontal band joining the eyes and another band round 

 the back of the neck are white. The throat and sides of the neck are white. The white throat 

 is bordered below by a black pectoral band, which is much narrowed in the centre and broadens 

 on each side. This is succeeded by a broader band of coffee-brown, which extends under the 

 wings on both sides. The belly and flanks are greyish black, thickly spotted with white. The 

 interior of the wings is crossed by a broad white band, formed by the inner webs of the remiges 

 being white at- their bases. The tail is black, tipped narrowly with white, and crossed about 

 halfway down by a white bar formed by white blotches on the inner webs of the tail-feathers. 

 The bill and legs are black.
