The specific term brasiliensis is rather an unfortunate one for this 

 bird, which seems most frequent in collections from Cayenne and 

 Guiana, though since, as Mr. Wallace has informed me, it is common 

 at Para and all along the Lower Amazon, the name cannot be said 

 to be altogether inaccurate. But in what is generally known to or- 

 nithologists as Brazil — about Bahia and Rio — the present bird does 

 not occur, and is replaced by another member of the family. 



This species seems to extend up the valley of the Amazon as far 

 as the confines of Eastern Peru. Specimens from the Ucayali in 

 Mr. Gould's collection are rather more brightly coloured, but present 

 the same characteristic castaneous blotch on the nape as the Cayenne 

 bird, and are not separable from this species.

Mr. Gould has obligingly lent me the type of his description of 

 this Motmot, which, as might be expected from the locality, appears 

 to be different from any other described species. It approaches most 

 nearly to M. Lessoni, which it resembles in the blue border of the
