Mr. Gould describes his Nyctihius bracteatus as from " Bogota." This may be a correct 

 locality, but, amongst many thousands of Bogota skins examined, we have never met with it. 

 A more certain patria is British Guiana, where Schomburgk obtained a single specimen. Hence 

 it extends over the Amazon valley as far as Pebas, where Messrs. Castelnau and Deville 

 obtained an example now in the Paris Museum. 



Nyctihius bracteatus is a very well-marked species, distinguished by its small size, red 

 colom-ing, and the quadrate white spots on the scapulars and plumage below. It cannot well 

 be confounded with any of the five other known species of the genus, which stand as follows, 

 taking the larger sized first : —
