From Eastern Ecuador G. chalcothorax extends over the forests drained by the Peruvian 

 Amazons or Maranon. Mr. Hauxwell obtained examples of it at Pebas ; and I have seen speci- 

 mens of it in other collections from Upper Amazonia. 



The upper plumage of G. leucogastra is generally of a dark rich shining copper. This 

 colour extends over the upper wing-coverts ; but the head, the outer margins of the secondaries, 

 and the upper surface of the tail-feathers are of a metallic green with bluish reflections in some 

 lights. The primaries are of a dull black. The black chin seems to be wider in extent than in 

 G. leucogastra, rendering the white throat-patch rather square in form : the breast is coloured 

 like the back. The lower belly is white, the feathers at their bases being black, but broadly 

 tipped with white. The inner margins of the remiges are also white ; but the under wing-coverts 

 are blackish. The under surface of the tail is slaty black, the outer rectrices on each side 

 having the tips and adjacent inner margins of the inner webs of a more or less decided white. 

 The bill and feet are black. The outer (abnormal) pair of rectrices are about an inch in length 

 from their insertion, the second pair rather more than two inches. 



In the female, as in the preceding species, the throat-patch and belly are of a pale yellowish 

 fulvous. 



The following are the dimensions of the examples of this species in my own collection and 

 that of Messrs. Salvin and Godman : —
