Nonnula ruficapilla. These were obtained at three places in the Brazilian province of Mato 

 Grosso, adjoining the Bolivian frontier — namely Villa Maria, Engenho do Cap. Gama, and 

 Ponte do Guapore. Villa Maria lies on the upper waters of the Paraguay : Engenho do Cap. 

 Gama (the sugar-mill of Captain Gama) and Ponte do Guapore (the bridge over the Guapore) 

 are situated near together on the Rio Guapore, a confluent of the Madeira, about fifteen leagues 

 below Villa Bella de Matogrosso. One of the skins procured by Natterer at the first of these 

 three stations, and which is now in my cabinet, fully agrees with UppeiVAmazonian specimens. 

 There can therefore be no doubt, I think, that Nonnula r%ijica])illa occurs in these two widely 

 separated localities ; and the probability is, of course, that it will hereafter be discovered to exist 

 in the intermediate region, wherever the soil and vegetation are suitable to its existence. 



Natterer found this species solitary in the forest, sitting on branches near the ground. He 

 describes the iris as dark brown in both sexes, the feet dark brownish grey, and claws black.
