There is some doubt respecting the habitat of this species. 

 Waterton's original specimen is stated to have been obtained by him 

 at the " Miribi Creek, about 40 miles up the Essequibo E,iver," but 

 no authentic specimens have of late years been found in Demerara. 

 On the other hand, Count von Berlepsch has recently received speci- 

 mens from Pernambuco, and Gould's examples were supposed by 

 him to have been obtained near the mouth of the Amazons.
