Nyctibius pectoralis, Gould, in Proc. of Zool. Soc. Part VI. 1838. 
This species inhabits the northern parts of Brazil. It is nearly allied to Caprimulgus Jamaicensis, but is 
much less in all its admeasurements ; it is also allied to, but differs from the Caprimulgus longicaudatus of 
Spix. 
The figures are of the natural size.
