This well-known bird is, as I have mentioned before, the only 

 species of Linnseus's genus Bucco. It was erroneously called ca- 

 pensis by him, which renders it necessary to adopt for its name 

 Latham's appellation collaris. Cayenne specimens occur in most 

 collections. Le Vaillant says it is also to be found in Guiana, 

 though Richard Schomburgk does not include it in his catalogue 

 of birds in the third volume of his ' Reisen in Britisch Guiana/ 

 It extends across the branches of the Rio Negro (whence ex- 

 amples were brought by Mr. Wallace) into the wood region of 

 the Peruvian provinces bordering on Brazil, where it was found 

 by Dr. Tschudi.

This is the largest species of the genus and one of the earliest 

 known. It appears to be rather widely distributed, since I 

 cannot find any real difference between Honduras examples 

 collected by Mr. Dyson and those from the Amazons. Schom-
